porated, of Saint Louis, in the State of Missouri, United States of America.
I, ARTHUR THOMAS ASHWELL, of Saint Peter's Church Walk, Nottingham, in
the County of Nottingham, Solicitor, do hereby declare the nature of this inven-
tion to be as follows:
This invention although capable of use in various different relations is shown
as an attachment for the well known form of calculating machine now upon the
market, which is manufactured under Patents No. 12,121 dated 22 August 1888 and
17,126 dated 12 September 1893.
Reference may be had to the specifications of these patents for a detailed explana-
tion of the operating mechanism of the machine, it being sufficient for the purpose
of the present application to illustrate and describe in detail the novel printing
attachment constituting my present invention.
As
The machine illustrating the application of the present improvements is
primarily an adding machine, and is extensively used in banks and counting
houses for listing the amounts of checks or other items and totalising the same.
this and other machines have been heretofore constructed and used the several
amounts of the checks or other items to be listed were printed in a single column
upon a paper strip carried in a supply roll upon the machine and led thence
through the printing attachment. It frequently happens in the ordinary use of
these machines that a very large number of items are consecutively listed, as in
banks, where a single machine may be used each day to list many thousands of
checks; and the result has been that in such instances, owing to the necessity for
printing the amounts in a single column the completed list was apt to consist of
an excessively long column of figures upon a single narrow strip of paper, thus
presenting the list in a somewhat inconvenient form for either examination or
handling and preservation.
It is the object of the present invention to provide a device adapted to receive
comparatively wide sheets of paper of any desired length, upon which the items
to be listed may be printed in successive columns side by side and any desired
length, the length of the columns being regulated as desired within the limits of
the length of the sheet of paper employed. To this end the invention consists in
a novel printing-attachment adapted to accommodate wide sheets of paper for the
purpose described, and by means of which the printing can be readily examined by
the operator at any time desired, and by which a series of columns of uniform
length may be readily and conveniently printed side by side upon the sheet of
paper. The amounts may be totalized at the bottom of each column and carried
forward to the top of the succeeding column if desired, or they may be totalized
only at the bottom of the last column in the series.
Having thus premised a general statement of the nature and object of the inven-
tion I will proceed to a more detailed explanation of it by reference to the accom-

A is the casing of the machine, containing the operating mechanism, which it
is unnecessary to illustrate or describe in detail. B are the numbered keys of the
machine, arranged in a series of parallel rows in the top of the casing, there being
nine keys in each row, as shown in Figs. 1 and 2, and there usually being nine
rows of the keys in the machines now in use. The keys in each row are numbered
consecutively from front to rear (from left to right in Fig. 1) with the nine digits,
and the several rows of keys represent defferent-denominations, that upon the right,
shown in Fig. 1 representing say units of cents, the next to the left tens of cents,
the next units of dollars, the next tens of dollars, and so on to the ninth or left
hand row, shown in Fig. 2, in which the keys represent millions of dollars. On
such a key-board any amount from one cent to 9,999,999 dollars and 99 cents
may be indicated, as will be readily understood without further explanation.
C is the operating lever of the machine, by means of which, after the proper
keys B to represent the amount to be added and printed have been slightly
depressed or set, the addition and printing are effected by pulling the lever C
forward to its limit of stroke, and then releasing it and and permitting it to return
to normal position, such return being effected by a suitable spring within the
machine.
So much of the printing mechanism as is necessary to an understanding of the
present invention is exposed to view by the broken away portion of the casing in
Fig. 1, where the series of type co-operating with the right hand row of keys is
shown. There are nine of such series or rows of types arranged side by side and
close together, one row corresponding to and co-operating with each of the rows
of keys B. The types in each row are arranged in five pairs, as shown, each pair
being carried by an independent type bar or plunger D, the five plungers D in
each row being mounted upon and carried by à sector plate E which is hung at
its extreme forward end upon a transverse rod extending across the upper central
part of the machine, not here shown. Each plunger D is provided with two
pins a, b, the former of which is normally seated in a notch in the edge of the
sector plate E and the latter of which projects through a slot in said plate and
serves to hold the plunger in position and guide it in its movement independently
of the plate E. The uppermost type in each row is a cipher and those below it
represent the nine digits in regular order from one to nine. A roller F, hereafter
referred to, constitutes the platen with which the types co-operate and an inking
ribbon G passes vertically between said roller, and the types.
The foregoing explanation will be sufficient for a general understanding of the
operation of the machine independently of the present invention, which operation

page_text: is as follows: When any key B in a given row is depressed and the lever C then
drawn forward to its limit of movement the sector plate E corresponding to such
row of keys will be first swung upward until its type corresponding to the operated
key is brought approximately to the printing point in front of the centre of the
platen roller F, and then, after being brought to such position, the plunger D
carrying such type is thrown rearward and presses the inking ribbon G against the
roller to print the amount represented by such type upon the strip or sheet of
paper which may be passed between the roller F and the inking ribbon G, after
which, upon the release of the lever C, the parts all return to their normal position.
Before proceeding to a detailed description of the novel printing device, I may
explain that in Fig. 1 the lowermost or left hand key B is partially hidden by a
special key H, which stands in front of such key B in said view. This key H is
the repeating key of the machine, by depressing which and engaging it in its
depressed position any of the keys B which have been previously depressed will be
retained in depressed or set position until the key H is released. By means of
the key H, therefore, whenever any given amount is to be successively printed
several times the proper keys B may be depressed and then maintained in depressed
position by means of the key H while the lever C is operated as many times as-it.
is desired to print the amount represented by such keys. In Fig. 2, also the
lowermost or right hand key B is partially hidden by a special key I, which is the
totalizing key. In addition to the means above described for printing at each
operation of the machine an amount corresponding to the particular keys B which
are operated or set at such operation, the machine is provided with means for
adding together the amounts printed at successive operations and preserving a
total of them, and whenever it is desired to print such total amounts, as at the foot
of a column of listed items, the special key I is depressed and the lever C operated,
whereupon such total amount will be printed upon the strip or sheet of paper at
the foot of the column. The key I is also employed as a releasing or re-setting key;
by means of which if an error be made in depressing the keys B and it be desired to
restore the depressed keys to normal position, it may be accomplished by depressing
the key I before the lever C is operated. The key I is also employed to restore
the keys B to normal position after they have been depressed and held in depressed
position by means of the key H during successive operations of the lever C as above
described. These special keys H and I form no part of the present invention and
are employed in the machines of this character now in general use, so that no
description of the particular means by which or manner in which they accomplish
the results above mentioned need be given here.
Having now explained so much of the old machine as is necessary to an under-
standing of the present invention, I will proceed to an explanation of the latter.
With the type of any character and their suitable operating appliances I combine
a platen or support for a sheet of paper-means for supporting the said platen so
that it can be set in different positions opposite the type, and means for moving the
platen or the paper a step as required to print the lines successively one under the
other in each position of the platen, to print columns of any desired length side
by side.
The platen may be of any desired construction and may be curved to a greater
or less degree of a size to support the entire sheet swinging about the centre of the
curve, or as shown it may be cylindrical.
In such case, as shown in Figs. 1 to 5 there are secured to the rear side of the
casing A of the machine, near its lower edge, two upwardly projecting and out-
wardly curved brackets or side frames J K which serve to support all of the devices
to be now described as part of the novel mechanism constituting the invention.
Journalled at its opposite ends in bearings in the upper ends of the respective side
frames J K is a shaft L upon which is secured a rubber faced feed roller M, in
this instance divided into three sections as shown in Figs. 4 and 5.
At its left hand end, Figs. 2, 3 and 4, the shaft L has fast upon it a ratchet N
with which co-operates a pawl 0, Fig. 2, carried by an arm P loosely hung at its

page_text: forward end upon the shaft L beside the ratchet N, and having connected to its
rear end the upper end of a link Q whose lower end is connected to the rear end
of an arm R which is secured at its forward end upon a rock shaft S journaled
in the side frame K and having rigidly secured upon its end opposite the arm R
an upwardly projecting and forwardly bent lever T, the lever T, rock shaft S, and
arm R constituting a bell crank lever having the shaft S as its fulcrum. A coiled
spring U connected at its upper end to the side frame K and at its lower end to
the arm R serves to pull the latter upward and yieldingly hold the bell, crank lever
and connected parts in normal position. The movement of such parts under the
stress of the spring U is limited by means of a thin arm or plate V carried by the
link Q and contacting at its upper end with a fixed stop pin W. Located within
the machine is a lever X, whose upper end is shown in Fig. 2, which lever is so
connected with the main operating lever C of the machine, by means unnecessary
to illustrate or describe here, that whenever the lever C is pulled forward to its
limit of movement the upper end of the lever X will be thrown rearward and a
stud Y which it carries be caused to contact with the lever T of the bell crank and
press the upper end of said lever slightly rearward, thereby rocking the bell crank
against the stress of the spring U and lowering the rear end of the pawl carrying
arm P, and thus permit the pawl () to slip over and engage the next lower tooth
upon the ratchet N of the feed roller M, with the result that when the operating
lever C is released and the parts return to normal position the pawl O will advance
the ratchet N the space of one tooth and turn the feed roller M a corresponding
distance.
The platen roller F, which is also preferably a rubber faced roller, bears upon
the roller M when the parts are in operative position, as in Figs. 1, 2 and 3, and
the strip or sheet of paper is passed between them, so that when the roller M is
actuated at each operation of the machine in the manner and by the means just
described the paper will be slightly advanced to bring a fresh surface to the
printing line. The roller F is mounted in a frame which is supported by and
adapted to be swung forwardly and backwardly upon and slid longitudinally of a
rod A¹ which is fixed at opposite ends in rearwardly projecting ears upon the
upper ends of the fixed side frames JK this rocking and longitudinal moving
frame constituting the paper carriage of the machine. The rod A is best shown
in Figs. 3, 4 and 5, being also shown in section in Fig. 7, and the opposite ends
of it, where it is fixed in the frames J K in Figs. 1, 2 and 6. The rocking frame or
paper carriage in which the roller l' is supported is best shown in Figs. 3, 4 and 5,
but also in Figs. 1, 2, 6 and 7. It consists of a cross bar B Figs. 3 and 5
provided at its opposite ends with upturned arms C¹ in which the opposite ends of
the spindle of the roller F are journaled, and provided upon opposite sides of its
middle with downwardly extending supporting arms D' whose lower ends surround
and fit the rod A¹, so as to freely turn and slide longitudinally upon the latter.
The paper carriage is thus free to be swung forward and backward so as to bring
the roller F into contact with the roller M, as in Fig. 2, or to carry it upward and
backward and away from said roller as in Figs. 5, 6 and 7, and is also free to be slid
longitudinally of the rod A¹ for a purpose hereafter explained. The right hand
side arm C of this paper carriage is prolonged a considerable distance beyond the
roller F to form a handle E¹ by means of which the frame may be rocked forward
and backward and moved along the rod A' as hereafter described.
Firmly secured at its opposite ends in the upper ends of the side arms C¹ (above
the journals of the spindle of the roller F) is a rod F¹ to the under side of which
is rigidly secured a curved paper guide G₁ extending forward over and fitting
against the upper surface of the roller F, the forward edge of this guide being
cut out as shown in Fig. 4 to form forwardly-extending fingers G₁ with wide
spaces between them. To further guide the sheet of paper around the roller F
there are provided curved springs H¹ Figs. 4 and 5, which are hooked at their
upper rear ends over the rod Fi (in grooves therein) and extend thence through
holes in the curved guide plate Gi and thence forward beneath the fingers G" of

page_text: the latter plate, and around the forward side of the roller F and thence rearward
beneath the same, and are secured at their lower rear ends to the lower paper
guide I' as best seen in Fig. 7 the latter consisting of a sheet metal strip extending
from side to side of the paper carriage, and secured at its forward edge upon lugs J₁
upon the upper surface of the cross bar B' of said carriage, as shown in Figs 3, 5
and 7. The rear edge of this plate I' is curved downwardly as shown, and near its
middle is provided with a depending guide way K¹ for a narrow strip of paper,
Figs. 3 and 6, for a purpose hereafter explained.
At its right hand end the spindle of the roller F projects through the side arm C¹
of the paper carriage and has secured upon it a milled thumb piece L', by means
of which the roller may be readily turned in either direction when thrown back-
ward away from the roller M, as in Figs. 6 and 7. In such position the sheet of
paper upon which the printing is to be done is inserted by placing its upper forward
edge upon the lower guide plate II, Fig. 7. and pressing it forward until it catches
between the under surface of the roller F and the spring guides H¹. Upon then
turning the roller F forward by means of the thumb piece L' at its right hand
end, the sheet of paper will be drawn forward and upward and carried thence rear-
ward beneath the upper guide G¹, and pass thence outward beneath the rear edge
of said guide as it is advanced. When the sheet of paper has been thus inserted
in proper position the paper carriage will be thrown forward and the roller F
allowed to rest upon the roller M as in Figs. 1, 2, 3 and 4, whereupon the movement
of the roller M at each operation of the machine, as heretofore explained, will cause
the roller F to turn with it and advance the sheet of paper. The several sections
of the roller M contact with the roller F in the spaces intermediate the spring
guides H passing around the roller F, as will appear from Figs. 4 and 5.
From the foregoing description it will be understood that upon inserting a sheet
of paper in the manner described and sliding the paper carriage to extreme right
hand position, the left hand end of the roller and left hand edge of the paper will
be brought opposite the printing point, and that with the parts in such position
a column of figures at the left hand side of the sheet of the paper may be printed
thereon by consecutive operations of the machine. It will be further understood
that after such a column has been printed, the paper carriage may be thrown
backward to carry the roller Faway from the roller M, and the roller F be then
turned backward by means of the thumb piece L' at its right hand end until the
head of the printed column is brought back to the printing line, and that upon
then sliding the paper carriage to the left the proper distance and throwing it
forward again and permitting the roller F to rest upon the roller M, the parts will
be in a position to print a second column of figures upon the sheet of paper, imme-
diately at the right of the first column; and that by repeating this manipulation a
series of columns of figures may in this manner be printed side by side upon the
sheet of paper.
The lower ends of the fingers G" of the upper paper guide G, Figs. 4 and 5, are
in about the horizontal printing line along the roller F, and they serve to indicate
when the roller has been turned backward far enough to bring the sheet of paper to
proper position to cause the first amount in the second and succeeding columns to
be printed in the same horizontal line as the first amount in the first column, so
that the heads of the several columns may all stand in horizontal line.
For the purpose of enabling the paper carriage to be readily adjusted laterally to
proper positions for printing the respective columns, and for locking it in its
different adjusted positions while the columns are being printed, and while the
carriage is swung backward and forward, the following means are provided. As
indicated by the spaces separated from each other by the spring guides H¹ in
Figs. 4 and 5, the arrangement of parts shown in the drawings is intended to
permit the printing of five columns side by side upon the sheet of paper; and the
rod A', as shown in those views and also in Fig. 3, is provided with five circum-
ferential grooves M' which are adapted to co-operate with a catch upon the sliding
paper carriage. As shown in Figs. 3 and 7 the catch which co-operates with these

page_text: grooves consists of a short arm N' which is fastened upon the left hand end of
a rock shaft O', which is journaled at one end in one of the supporting-arms Di
of the paper carriage and at its opposite, end in a rearward extension P of one of
the side arms C₁ of said carriage, and has fastened upon it at its latter end an
upwardly extending lever Q' having its upper end shaped to form a finger piece
in convenient relation to the upper end of the handle E for the two to be grasped
between the thumb and forefinger of the operator. A coiled spring surrounding
the rock shaft O', and secured at one end to said shaft and at its opposite end to
the bearing P of the shaft presses the latter in a direction to engage the catch N'
with the grooves M in the rod A¹. The catch may be disengaged from the
grooves in the rod by pressing the upper end of the lever Q' toward the handle E',
which is conveniently done by grasping the two between the thumb and forefinger
and simply squeezing them together. The operator will grasp the handle E¹ of
the paper carriage and the upper end of the lever Q1, and swing the paper carriage
backward to the position shown in Figs. 6 and 7. He will then press the lever Q¹
toward the handle E' far enough to disengage the catch N from the extreme right
hand groove M' in the rod A' (the left hand groove in Fig. 3) and then slide the
paper carriage toward the left, releasing the lever Q' and continuing the movement
of the carriage toward the left until the catch N' springs into the next groove M¹
in the rod A. This will arrest the paper carriage and lock it in proper position
for the printing of the second column. The operator will then turn the roller F
backward (by means of the thumb piece L') until the sheet of paper is brought
into proper position to begin printing at the head of the second column, and will
then swing the paper carriage forward to normal position and resume the operation
of the machine.
In this manner and by these means the printing of the several columns side by
side and at equal distances from each other may be readily effected without the
exercise of any great care or skill on the part of the operator in adjusting the parts
for such purpose.
To further guard against and positively prevent the printing of the columns
upon the paper sheet except in proper relation to each other the following locking
device is provided, which prevents the paper carriage being slid laterally except
when swung backward to the position shewn in Figs. 6 and 7, and which prevents
its being swung forward again to normal position except when its lateral adjust-
ment is such that it is in proper position for the printing of a column of figures
upon the sheet of paper. The left hand one of the two supporting arms D¹ of the
paper carriage in Fig. 3 is extended downwardly below the rod A', and when the
paper carriage is swung backward to the position shown in Fig. 7 this extension of
the arm D contacts with a fixed rod R and limits the backward movement of
the parts. The under side of the rod A¹ is cut away or grooved longitudinally, as
at Si in Fig. 7, and the extension of the arm 11 above mentioned has secured to
it a plate T Figs. 3 and 7, whose upper end fits in said groove S¹ when the paper
carriage is in rearward position, and travels in said groove as the carriage is moved
laterally. When the carriage is thrown forward to normal position the upper
end of this plate T passes out of the groove in the shaft A' and enters one of the
circumferential grooves in said rod. When the paper carriage is in forward posi-
tion, therefore, the engagement of this plate T with the circumferential groove M¹
in the rod A¹ will prevent lateral movement of the carriage, and it will be necessary
to swing the carriage rearward and carry the plate T¹ out of the circumferential
groove and into line with the longitudinal groove, before the carriage can be moved
laterally. Likewise, when the carriage is moved laterally, after being thus swung
rearward, the plate T¹ must be brought into line with another one of the circum-
ferential grooves in the rod A" before the carriage can be thrown forward again to
normal position. The co-operation of this plate T with the circumferential and
longitudinal grooves in the rod A¹ thus prevents the paper carriage being moved
laterally, while in forward position, and when swung rearward it prevents its being

page_text: swung forward again until it is in proper position for the printing of a column of
figures.
The remaining feature of the invention relates to the provision of an automatic
alarm or signalling device, to indicate the approach of the printed column to the
lower end of the sheet of paper, so that the operator may not inadvertently continue
the operation of the machine beyond the proper point for the lower end of the
column, and by means of which, also, uniformity in the lengths of the several
columns may be attained without careful watching on the part of the operator and
consequent interference with his rapid operation of the machine this signalling
device serving a similar purpose in respect to the lengths of the columns of figures
that the signalling device upon the ordinary typewriter serves in respect to the
lengths of the lines. Journaled at its opposite ends in the side frames J K, below
and in front of the shaft L of the feed roller M, is a shaft,A2, Figs. 1 to 7. Rigidly
secured to the extreme right hand end of the shaft A2 at the outer side of the frame J
is an upwardly and rearwardly projecting arm B2, Figs. 1, 3, 4 and 5 and 6, while
rigidly secured to the extreme left hand end of the shaft A2, outside the frame K,
is a corresponding upwardly and rearwardly projecting arm C³, Figs. 2, 3, 4 and 5.
The upper rear ends of these two arms B, C, are rigidly connected by a transverse
bar D, Fig. 3, so that the two side arms and the connecting bar De constitute a
pivoted or swinging frame having the rock shaft A2 for its fulcrum or pivot. A
coiled spring E³ surrounding the shaft A2 at its left hand end, and connected at
one end to said shaft and at its opposite end to the side frame K, presses the swinging
frame upward and yieldingly holds it in the position shown in Figs. 1, 2 and 3. As
indicated in Fig. 2 and clearly shown in Fig. 6, the right hand side arm B2 of this
swinging frame is forked to form a second arm F which has pivoted to its rear end
a striker lever G2 yieldingly held in normal position by a coiled spring H³ and
adapted to be actuated by means hereafter described to sound a gong or signal
bell 12 which is carried by the lower end of an arm or rod Ja fixed at its upper end
in the side frame J. Loosely mounted upon a stud projecting from the arm B
(and hereafter more fully described) is a gear wheel K2, Fig. 1, which meshes with
a pinion L³ fast upon the end of the feed roller shaft L, when the swinging frame is
in its upper normal position, and which becomes disengaged from said pinion when
said frame is depressed in the manner hereinafter described. The normal engage-
ment of the gear K with the pinion L on the feed roller shaft causes the gear K³
to be turned slightly at each operation of the machine. Now, the gear K carries a
trip device adapted to co-operate with the forwardly projecting arm M2 of the
striker Gs, to retract Baid striker and release it and permit its
spring HS to throw it against the gong and sound the latter. As
hereafter described this trip for the gong striker is adjustable around
the gear
Ka and the gear is provided with
⚫ an indicator ог dial
as seen in Fig. 1. In the present instance the gear has 100 teeth, and the indicator
or dial 100 divisions, and at each operation of the machine the gear wheel is advanced
the space of one tooth. By adjusting the trip around the gear wheel, to different
points on the dial, it may be caused to engage the gong striker at different pre-
determined points in the forward movement of the gear wheel from initial position,
with the result that the trip may be adjusted to sound the gong at the end of any
predetermined number of operations of the machine; after which, by depressing
the swinging frame which carries the gear wheel the latter may be disengaged from
the pinion L of the feed roller shaft and turned backward to initial position. To
illustrate, if it be desired to print. columns of figures having fifty amounts in each
column the trip will be set at such a point upon the gear wheel that it will require
fifty forward movements of the latter from initial position to sound the gong. The
operator will, therefore, continue his operation of the machine until the gong is
sounded, which will occur at the end of the fiftieth operation of the machine, and
will then shift the paper carriage and paper to position for the next column, in the
manner heretofore described, and reset the gear wheel to initial position. He will
gong

page_text: then resume his operation of the machine and continue it until the gong is again
sounded, which will occur at the end of the hundredth (or second fiftieth) operation
of the machine; and so on until the sheet of paper is filled with columns of equal
length, each containing fifty amounts.
Having now explained in a general way the purpose and operation of the signal-
ling device, I will proceed to a more detailed description of the construction and
mode of operation. The arm B2 is provided with a hole N2, Fig. 6, in which fits
one end of a stud or small stud shaft Os, as clearly shown in the enlarged detailed
view in Fig. 9. The shaft O2 is provided with an enlargement or collar P* fitting
against the outer side of the arm B of the swinging-frame, and the reduced portion
of the shaft which passes through the hole in said arm is threaded and has
screwed upon its end a nut Qs, by means of which the shaft 02 is rigidly secured
in the arm B³, a washer R³ being interposed between the nut Q and arm B. The
gear wheel K is loosely mounted upon the shaft 0%, and is provided upon its outer
side with an extended hub or sleeve S³ surrounding, the shaft 0%, and upon its
opposite side it is provided with a cylindrical casing T whose end is closed by a cap
or disc U. The gear wheel is held in position upon the shaft 03 by a disc Va
secured to the front end of the shaft Os by means of a screw W³, said disc co-operat-
ing for that purpose with the front end of the hub or sleeve S2 of the gear wheel.
Located within the casing T upon the opposite side of the gear wheel is a coiled
spring X whose inner end is secured to the shaft 03 and whose
outer end is secured to a split friction ring Y tightly fitted within
the casing T, as shown in Figs. 8 and 9. As the gear wheel K³ is turned forward
upon the shaft L by the operation of the machine, in the direction of the arrow in
Fig. 8, it will wind up the spring X2 and put it under tension, so that when the
gear wheel is released and left free to turn backward said spring will serve to turn
it in that direction. The operation of the parts in this respect would be the same
if the outer end of the spring were secured directly to the gear or its casing T³, the
purpose of connecting it with said casing by means of the split friction ring Ya
being to furnish a connection with the gear wheel which will yield when the gear
wheel is turned beyond a certain limit and prevent breaking of the spring.
The gear wheel K³ is provided upon its inner face with a projecting stud A³,
Fig. 8, which is adapted to co-operate with a stop B3 located upon the side arm B³
of the swinging frame, as shown in Fig. 6 and in dotted lines in Fig. 8. When the
gear wheel is in intial or zero position its stud A³ is in contact with the rear end of
the stop B3 and the latter serves to limit the backward movement of the gear wheel
under the stress of the spring X2. As the machine is operated and the gear wheel
turned forward from initial position its stud A³ is carried away from the stop B³.
When the gong is sounded, at the end of a column, and the swinging frame is
depressed and the gear wheel K³ thereby disengaged from the pinion L³ on the feed
roller shaft; as heretofore explained, the spring X³, will turn the gear wheel back-
ward until its stud A³ contacts with the stop B³, thereby arresting the gear wheel
in initial position. The stop B3 upon the side arm of the swinging frame might be
simply a rigid projection on such side arm, but in the present instance it consists of a
short lever pivoted upon said arm and yieldingly held in normal position by a spring C³,
Figs. 6 and 8. This construction and arrangement permits the stop to yield and
allow the stud A3 to pass it in a forward direction if the gear wheel should be turned
forward more than a complete revolution, as might be the case in the printing of
long columns upon a long sheet of paper. For the purpose of printing columns
of anything less than 100 numbers, however, a rigid projection upon the side arm
of the swinging frame would serve the same purpose as the yielding stop, although
the latter is convenient in assembling the parts in that it enables the spring within
the casing of the gear wheel to be readily put under tension by initially turning
forward the gear wheel a revolution or two.
The adjustable trip carried by the gear wheel consists of a pointer D³, Figs. 1
and 9, whose extreme outer end projects beyond the periphery of the gear wheel
and co-operates with the arm M of the striker lever. At its inner end the pointer D³

page_text: is secured to or formed integral with a sleeve E³ surrounding the gear wheel hub
or sleeve S³, and enlarged at its forward end at F³ to form a housing within which
is confined a coiled spring G³, said spring bearing at its outer end against the
disc secured to the front end of the shaft O2, and at its inner end against the
internal annular shoulder of the housing F3. The spring G³ presses the sleeve E³
inwardly and holds the pointer D³ against the face of the gear K, in which position
one or more short inwardly bent fingers H³ upon the outer end of the pointer D³ fit
between the teeth of the gear wheel and thereby lock the pointer to the wheel. The
pointer may be disengaged from the wheel by pulling the sleeve E outwardly
against the resistance of the spring G³, for which purpose the outer surface of the
housing of the sleeve is roughened or milled as shown in Figs. 3, 4 and 5.
The pointer can then be turned around the gear wheel and re-engaged therewith
at any point desired. In Fig. 1 the gear. wheel is shown in the initial or normal
position which it occupies at the beginning of the printing of a column of figures,
and the pointer or trip is set to such position that it will cause the striker to sound
the gong at the end of fifty operations of the machine. This would be the adjuste
ment of the parts for printing columns having fifty amounts. If columns of
twenty five numbers were to be printed the pointer would be turned to the
number 25 upon the dial of the gear wheel, while for columns of 75 numbers it
would be turned in the opposite direction to the number 75 upon the dial. In this
manner by first setting the pointer at any desired number upon the dial the gong
will be sounded at the end of that number of operations of the machine.
For the purpose of facilitating the release and resetting of the gear wheel and
its pointer or trip at the shifting of the paper carriage at the end of the printing
of one column of figures and preparatory to the printing of the next column, the
following means are provided for automatically disengaging the gear wheel from
the pinion of the feed roller shaft by the act of shifting the paper carriage laterally
from the position of one column to another. As seen in Fig. 3 the cross bar D
of the swinging frame which carries the gear wheel K² is provided in its upper
edge with equi-distant notches or depressions J³ and the left hand supporting
arm of the paper carriage in Fig. 3 is provided upon its rear side with a lug K³
adapted to co-operate with the bar D. (See also Figs. 6 and 7). When the
paper carriage is in any one of its proper adjusted positions this lug K³ upon the
arm D will stand in line with one of the notches J³ in the bar D. In Fig. 3 it
is opposite the third notch from the left in that view. If the paper carriage be
now swung backward to the position shown in Figs. 6 or 7 the lug K³ will simply
enter the notch in the bar I and not move the latter, but when, after being swung
back, the paper carriage is slid laterally toward position for the printing of the
next column the lug K³, riding over the inclined side of the notch J³ in which it
had been resting, will depress the bar 12 and thereby swing downward the frame
of which said bar forms a part and which carries the gear wheel K³. This depres-
sion of the swinging frame will disengage the gear Ks from the pinion L2 of the
feed roller shaft, whereupon the gear wheel will be immediately turned backward
to normal position by its spring X³, as heretofore explained.
In the manner and by the means above described, therefore, the gear wheel and
trip for the gong striker are automatically released and reset to normal position at
each shifting of the paper carriage from one printing position to another, so that
having first set the trip at any given number upon the dial of the gear wheel the
operator need pay no further attention to the adjustment of the signalling device so
long as he desires to continue printing columns containing that number of
amounts in each column. When he reaches the end of the first column the gong
will be sounded, and he will swing the paper carriage, backward, shift it laterally
to position for the next column, turn the sheet of paper backward to bring the
head of the column to printing position and then swing the paper carriage forward
to normal position, and proceed with the operation of the machine until a second
sounding of the gong notifies him that the end of the second column has been
R

page_text: reached; whereupon he will repeat the above described manipulation until the
sheet of paper has been filled with columns of uniform length.
The employment of this new printing attachment, for printing parallel columns
upon wide sheets of paper, does not prevent the use of the machine for printing
single columns upon long and narrow strips of paper, as heretofore. In Fig. 3
there is shown in dotted lines a roll of paper strip supported in the framework,
and the strip led thence upward through the paper guide K' heretofore referred
to, whence it would pass forward over the paper guide 1' (Figs. 6 and 7) and thence
upward around the platen roller F, as will be readily understood.
It will be understood from the description which has been given that the inven-
tion, in its broader scope, is not restricted to the details of construction and arrange-
ment of parts which have been illustrated and described, but consists in the new
combinations and modes of operation which have been set forth, and that while
preserving the essential features of the invention in this respect the details of
construction and arrangement may be widely varied. To illustrate, in Figs. 10 to
13 I have shown a modified construction and arrangement of the parts in which,
the swinging frame of the paper carriage, which carries the platen roller F,
instead of being mounted to swing upon and slide longitudinally of the round rod A',
herefore described, has the lower rear ends of its side arms C pivoted at a to ears b
projecting upward from the opposite ends of a sliding frame A' which frame is
mounted upon a fixed cross-bar B rigidly secured to arms or brackets c projecting
rearwardly from the upper ends of the side frames J K, this fixed cross bar occupy-
ing substantially the same position in the modified construction as does the rod A¹
in the construction first described. The frame A is free to be slid longitudinally
upon the bar B, and to relieve the friction between the parts ball bearings are
interposed between them as shown at e, the cross bar being provided upon its
front and rear sides with longitudinal grooves, and the sliding frame A* being
provided with coincident grooves, to accommodate the balls.
The sliding frame A constitutes part of the paper carriage, and accommodates
the lateral adjustments of the latter for the printing of different columns, while the
backward and forward movements of the carriage, to carry the roller F into and
out of contact with the roller M, are permitted by the pivotting or hinging of the
side arms C of the swinging frame to the ears 6 of the sliding frame A at a, as
before explained. So far as the mere hingeing of this swinging frame is concerned
its pivots a might be simply studs or screws projecting from the ears b but in the
present instance its right hand pivot a, Fig. 10, is a rock shaft, which, as shown
in Fig. 13, extends through the right hand side arm C', and through the adjacent
ear upon the sliding frame A, and thence onward to a point adjacent the middle
of the machine, where its left hand end is journaled in a bearing f upon the rear
side of the cross bar B₁ of the swinging frame Figs. 12 and 13.
The fixed cross bar B has secured to or formed integral with its upper side a
longitudinal rib g, which rib, as shown in Fig. 13, is provided at intervals with
transverse notches h, these notches corresponding in purpose and function to the
circumferential grooves M¹ of the rod A¹ in the main construction Figs. 3 and 5,
As shown in
and occupying a similar position relatively to the other parts.
Figs. 12 and 13 the cross bar B¹ of the swinging frame has rigidly secured to it
adjacent the left hand end of the rock shaft a (right hand end in Fig. 13) a sector
plate i which is adapted to travel back and forth in the respective notches h in the
rib g when brought into line therewith and the frame then swung backward and
forward upon its pivotal supports a. As shown in Fig. 12 this plate i is of such size
and so located that when the swinging frame is in forward position the plate will
rest in one of the notches h in the rib g, and prevent the paper carriage being slid
longitudinally of the bar B. When the swinging frame is swung backward to
its limit of movement, however, this locking plate i will be carried forward and out
of the notch h in which it has been resting, so that the paper carriage is then free,
so far as the co-operation of this plate with the notches h in the rib is concerned,
to be slid along the bar B', but cannot be swung forward to normal position again

page_text: except when the locking plate i is brought into line with one of the notches h in
the rib.
The paper carriage is, however, provided with an additional latch or locking
device controlling its lateral adjustments, of which the rock shaft a, Fig. 13,
heretofore referred to, forms a part. As shown in Figs. 10 and 13 this rock shaft
has secured upon its extreme right hand end (left hand end in Fig. 13) an upwardly
extending arm or handle C+, corresponding to the arm or handle Qin the main
construction. The hub of this arm is provided with a projecting shoulder, Fig. 10,
which co-operates with a stop upon the side arm CI of the swinging frame, to
limit the backward movement of the arm and rock shaft a under the stress of the
coiled spring surrounding the rock shaft, as shown in Fig. 13. As shown in
Figs. 12 and 13 the rock shaft has secured upon its opposite end an arm whose
outer end is of substantially the same thickness and stands in line with the locking
plate heretofore described. When the handle C and connected parts are in
normal position, and the swinging frame is swung backward to its limit of move-
ment the outer end of the arm will enter the rear side of the notch h in the rib g
before the rear edge of the locking plate is carried entirely out of such notch,
with the result that the sliding paper carriage is not released from. the notch by
merely swinging the frame backward to its limit of movement, being locked by
the arm before it is entirely released by the plate i. To then release the paper
carriage and permit it to be slid longitudinally of the bar B it is necessary to
press the upper end of the handle C upward or forward toward the finger piece E¹
of the side arm C₁ of the swinging frame, as in the case of the arm Q¹ and its
latch in the main construction. When the arm C is thus pressed toward the
arm C¹ the shaft a will be rocked and its arm thrown rearward out of the notch h
in the rib g, and thereby release the paper carriage and permit it to be slid along
the bar B to the position for printing the next column. In adjusting the paper
carriage, in the ordinary operation of the machine, the frame carrying the platen
roller will be first swung backward to its limit of movement, and the finger piece
of the arm C pressed toward the finger piece of the side arm of the swinging
frame, and then as soon as the paper carriage has been slid laterally far enough
to prevent re-engagement of the locking arm with the notch in the rib g the
arm C will be released, and the spring surrounding the rock shaft a permitted
to press the parts back toward normal position. The action of the spring will
press the arm against the rear side of the rib g, and it will slide along the latter,
as the paper carriage is moved, until it comes opposite the next notch in the
rib g whereupon it will spring into such notch and thereby arrest the paper carriage
in position for printing the next column, and the frame carrying the platen roller
will then be swung forward to normal position and the operation of the machine
be resumed. The arm C and the latch controlled by it therefore serve as a means
for readily determining the positions of the paper carriage.
l
The operation of the signalling device, and its co-operation with the paper
carriage whereby the trip is automatically reset to normal position at the shifting
of the paper carriage from one printing position to another, are substantially the
same as in the construction heretofore described, the only differences being in the
positions of the parts, the swinging frame which carries the gear wheel K² extend-
ing forward from its pivotal support, instead of rearward, and the stop 133 which
arrests the gear wheel in initial position when it has been released by its dis-
engagement from the pinion L² of the feed roller being located at the under side,
instead of at the upper side, of the wheel, as shown in Fig. 10. The notched cross
bar of the swinging frame carrying this gear wheel, which corresponds to the
bar D³ of the main construction (Fig. 3) is shown at D in Fig. 12, where it will
be seen that it co-operates with an arm E secured to and depending from the
forward side of the sliding arm A+ and engaging the rear edge of the bar D*.
This bar is secured at its opposite ends to the upper ends of two arms D5
fastened at their lower ends to a rock-shaft D, to whose extreme right hand end
the arm B³ carrying the gear wheel K³ is secured. When the sliding frame A' is

page_text: moved longitudinally of the bar D', in adjusting the paper carriage from one print-
ing position to another, the lower end of the arm E engaging the rear edge of the
bar D' will press the latter forward and thereby rock the shaft D and throw the
arm B forward and downward, and disengage the gear wheel Ks from the pinion L³,
as will be readily understood.
At the left hand side of the machine, Fig. 11, the arrangement of the parts for
actuating the feed roller M is slightly but not materially different from that shown
in the main construction and heretofore described. The rock shaft S which is
actuated by the contact of the stud Y (on the lever X Fig. 2) has secured upon its
extreme left hand end a forwardly extending arm F to which is pivoted the lower
end of a link G' whose upper end is pivoted to the pawl carrier P carrying the
pawl O co-operating with the ratchet N on the shaft of the feed roller M. The
arm F is provided with two holes a¹, 61, connected by a slot c¹, and the lower end
of the link G carries a stud d¹, which fits in and co-operates with the holes a¹ bl
and may be shifted from one to the other. When engaged with the hole b¹, which
is nearer the fulcrum of the arm or lever F, a less throw will be given the link G⭑
and the pawl-carrier and pawl than when the lower end of the link is swung
forward and its stud engaged with the hole a¹. The adjustment of the parts is
such that when engaged with the hole 61, as in Fig. 11, the pawl O will slip back-
ward over one tooth of the ratchet N and advance the latter the space of one tooth,
at each operation of the machine, while when the lower end of the link is swung
forward and its stud engaged with the hole a', and the pawl will be given twice
as much throw at each operation of the machine and the feed roller and paper
therefore advanced twice as far as under the first mentioned adjustment. By this
means the machine may be adjusted to print the items close together in each
column, or farther apart, as may be desired.
In addition to the paper guides about the platen roller F, I have provided in
the modified construction a pressure roller H bearing upon the upper side of the
platen roller F. The spindle of this roller is mounted at its opposite ends in the
front ends of levers I pivoted to the side arms C₁ of the swinging frame, and
engaged at their rear ends by springs J, Figs. 10 and 11, which serve to press
the roller H into contact with the roller F. The lever I at the left hand side of
the machine, Fig. 11, is provided with three arms, the upper vertically extending
one of which K forms a handle by which the roller H may be lifted out of contact
with the roller F. The roller H is composed of sections which bear upon the
roller F between the spring guides passing around the latter, as will be readily
understood withou. illustration.
While I have shown carriages of certain forms for supporting the platen it will
be evident that the construction may be changed, especially if a different character
of platen is employed, and the carriage or the platen thereof of course may be
mounted to swing or slide back and forth to and from the type in any suitable
manner.
If desired instead of a long roller M, as shown, the platen may be turned by
contact with a single disc or pulley at the centre of the shaft L, or any other suit-
able gear or means from said shaft or other operating part of the machine.

page_text: Improvements in Printing Attachments for Calculating machines.
▲ communication from abroad by The AMERICAN ARITIIMOMETER COMPANY, Incor-
porated, of Saint Louis, in the State of Missouri, United States of America.
I, ARTHUR THOMAS ASHWELL, of Saint Peter's Church Walk, Nottingham, in
the County of Nottingham, Solicitor, do hereby declare the nature of this inven-
tion, and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:-
This invention although capable of use in various different relations is shown
as an attachment for the well known form of calculating machine now upon the
market, which is manufactured under Patents Nos. 12,121 of 22nd August 1888
and 17,126 of 12th September 1893.
Reference may be had to the Specifications of these patents for a detailed explana-
tion of the operating mechanism of the machine, it being sufficient for the pur-
pose of the present application to illustrate and describe in detail the novel print-
ing attachment constituting my present invention.
The machine illustrating the application of the present improvements is
primarily an adding machine, and is extensively used in banks and counting
houses for listing the amounts of checks or other items and totalising the same.
As this and other machines have been heretofore constructed and used the several
amounts of the checks or other items to be listed were printed in a single column
upon a paper strip carried in a supply roll upon the machine and led thence through
the printing attachment. It frequently happens in the ordinary use of these
machines that a very large number of items are consecutively listed, as in banks,
where a single machine may be used each day to list many thousands of checks;
and the result has been that in such instances, owing to the necessity for print-
ing the amounts in a single column the completed list was apt to consist of an
excessively long column of figures upon a single narrow strip of paper, thus pre-
senting the list in a somewhat inconvenient form for either examination or hand-
ling and preservation.
It is the object of the present invention to provide a device adapted to receive
comparatively wide sheets of paper of any desired length, upon which the items
to be listed may be printed in successive columns side by side and any desired
length, the length of the columns being regulated as desired within the limits of
the length of the sheet of paper employed. To this end the invention consists
in a novel printing attachment adapted to accommodate wide sheets of for the
.paper
purpose described, and by means of which the printing can be readily examined
by the operator at any time desired, and by which a series of columns of uniform
length may be readily and conveniently printed side by side upon the sheet of
paper The amounts may be totalized at the bottom of each column and carried
forward to the top of the succeeding. column if desired, or they may be totalized
only at the bottom of the last column in the series.
Having thus premised a general statement of the nature and object of the
invention I will proceed to a more detailed explanation of it by reference to the
drawings accompanying the Provisional Specification, in which Figure 1 is a side
elevation of the right side of a machine such as described and embodying the
present invention, with a portion of the casing of the machine broken away to
expose the printing devices; Fig. 2 a corresponding view of the left side of the
machine; Fig. 3 a rear elevation of the machine with the parts in the position
shown in Fig. 1; Fig. 4 a front elevation of the printing attachment removed

page_text: direction of the arrows in Figs. 6 and 7, with the paper carriage thrown back as

on the line 77 of Fig. 4; Fig. 7 a sectional detail of the grooved shaft; Fig. 8
an enlarged detail of the gear wheel of the bell-ringing device, with its spring
casing in section; Fig. 9 a vertical section of Fig. 8 and associated parts; Fig. 10
an elevation of the right side of the printing attachment showing a modified con-
struction and arrangement of the parts; Fig. 11 a corresponding view of the
left side of the printing attachment; Fig. 12 a vertical section of the same on
the line 12-12 of Fig. 13; and Fig. 13 a detail view partly in rear elevation and
partly in section. The same letters of reference are used to indicate correspond-
ing parts in the several views.
A is the casing of the machine, containing the operating mechanism, which
it is unnecessary to illustrate or describe in detail. B are the numbered keys of the
machine, arranged in a series of parallel rows in the top of the casing, there being
nine keys in each row, as shown in Figs. 1 and 2, and there usually being nine
rows of the keys in the machines now in use. The keys in each row are numbered
consecutively from front to rear (from left to right in Fig. 1) with the nine
digits, and the several rows of keys represent different denominations, that upon
the right, shown in Fig. 1, representing say units of cents., the next to the left
tens of cents, the next units of dollars, the next tens of dollars, and so on to the
ninth or left hand row, shown in Fig. 2, in which the keys represent millions of
dollars. On such a key-board any amount from one cent to 9,999,999 dollars
and 99 cents. may be indicated, as will be readily understood without further
explanation.
C is the operating lever of the machine, by means of which, after the proper
keys B to represent the amount to be added and printed have been slightly
depressed or set, the addition and printing are effected by pulling the lever C
forward to its limit of stroke, and then releasing it and and permitting it to return
to normal position, such return being effected by a suitable spring within the
machine.
So much of the printing mechanism as is necessary to an understanding of the
present invention is exposed to view by the broken away portion of the casing
in Fig. 1, where the series of type co-operating with the right hand row of keys
is shown. There are nine of such series or rows of types arranged side by side
and close together, one row corresponding to and co-operating with each of the
rows of keys B. The types in each row are arranged in five pairs, as shown, each
pair being carried by an independent type bar or plunger D; the five plungers D
in each row being mounted upon and carried by a sector plate E which is hung
at its extreme forward end upon a transverse rod extending across the upper
central part of the machine, not here shown. Each plunger D is provided with
two pins a, b, the former of which is normally seated in a notch in the edge of
the sector plate E and the latter of which projects through a slot in said plate and
serves to hold the plunger in position and guide it in its movement independently
of the plate E. The uppermost type in each row is a cipher and those below it
represent the nine digits in regular order from one to nine. A roller F, here-
after referred to, constitutes the platen with which the types co-operate and an
inking ribbon G passes vertically between said roller, and the types.
The foregoing explanation will be sufficient for a general understanding of the
operation of the machine independently of the present invention, which opera-
tion is as follows: When any key B in a given row is depressed and the lever C
then drawn forward to its limit of movement the sector plate E corresponding to
such row of keys will be first swung upward until its type corresponding to the
operated key is brought approximately to the printing point in front of the centre
of the platen roller F, and then, after being brought to such position, the plunger D

page_text: carrying such type is thrown rearward and presses the inking ribbon G against
the roller F to print the amount represented by such type upon the strip or sheet
of paper which may be passed between the roller F and the inking ribbon G, after
which, upon the release of the lever C, the parts all return to their normal position.
Before proceeding to a detailed description of the novel printing device, I may
explain that in Fig. 1 the lowermost or left hand key B is partially hidden by a
special key H, which stands in front of such key B in said view. This key H
is the repeating key of the machine, by depressing which and engaging it in its
depressed position any of the keys B which have been previously depressed will
be retained in depressed or set position until the key H is released. By means
of the key H, therefore, whenever any given amount is to be successively printed
several times the proper keys B may be depressed and then maintained in
depressed position by means of the key H while the lever C is operated as many
times as it is desired to print the amount represented by such keys. In Fig. 2,
also the lowermost or right hand key B is partially hidden by a
special key I, which is the totalizing key. In addition to the means
above described for printing at each operation of the machine an amount
corresponding to the particular keys B which are operated or set at such
operation, the machine is provided with means for adding together the amounts
printed at successive operations and preserving a total of them, and whenever it
is desired to print such total amounts as at the foot of a column of listed
items, the special key I is depressed and the lever C operated, whereupon such total
amount will be printed upon the strip or sheet of paper at the foot of the column.
The key I is also employed as a releasing or re-setting key, by means of which if
an error be made in depressing the keys B and it be desired to restore the depressed
keys to normal position, it may be accomplished by depressing the key I before
the lever C is operated. The key I is also employed to restore the keys B to
normal position after they have been depressed and held in depressed position by
means of the key H during successive operations of the lever C as above described.
These special keys H and I form no part of the present invention and are employed
in the machines of this character now in general use, so that no description of the
particular means by which or manner in which they accomplish the results above
mentioned need be given here.
Having now explained so much of the old machine as is necessary to an
understanding of the present invention, I will proceed to an explanation of the
latter.
With the type of any character and their suitable operating appliances I
combine a platen or support for a sheet of paper-means for supporting the said
platen so that it can be set in different positions opposite the type, and means
for moving the platen or the paper a step as required to print the lines successively
one under the other in each position of the platen, to print columns of any desired
length side by side.
The platen may be of any desired construction and may be curved to a greater or
less degree of a size to support the entire sheet swinging about the centre of the
curve, or as shown it may be cylindrical.
In such case, as shown in Figs. 1 to 5 there are secured to the rear side of the
casing A of the machine, near its lower edge, two upwardly projecting and out-
wardly curved brackets or side frames JK which serve to support all of the
devices to be now described as part of the novel mechanism constituting the inven-
tion. Journalled at its opposite ends in bearings in the upper ends of the re-
spective side frames J K is a shaft L upon which is secured a rubber faced feed
roller M, in this instance divided into three sections as shown in Figs. 4 and 5.
At its left hand end, Figs. 2, and 4, the shaft L has fast upon it a ratchet N
with which co-operates a pawl O, Fig. 2, carried by an arm P loosely hung at its
forward end upon the shaft L beside the ratchet N, and having connected to its
rear end the upper end of a link Q whose lower end is connected to the rear end
of an arm R which is secured at its forward end upon a rock shaft S journaled in

page_text: the side frame K and having rigidly secured upon its end opposite the arm R. an
upwardly projecting and forwardly bent lever T, the lever T, rock shaft S, and
arm R constituting a bell crank lever having the shaft S as its fulcrum: A coiled
spring U connected at its upper end to the side frame K and at its lower end to
the arm R serves to pull the latter upward and yieldingly hold the bell crank lever
and connected parts in normal position. The movement of such parts under the
stress of the spring U is limited by means of a thin arm or plate V carried by the
link Q and contacting at its upper end with a fixed stop pin W. Located within
the machine is a lever X, whose upper end is shown in Fig. 2, which lever is so
connected with the main operating lever C of the machine, by means unnecessary
to illustrate or describe here, that whenever the lever C is pulled forward to its
limit of movement the upper end of the lever X will be thrown rearward and a
stud Y which it carries be caused to contact with the lever T of the bell crank and
press the upper end of said lever slightly rearward, thereby rocking the bell
crank against the stress of the spring U and lowering the rear end of the pawl
carrying arm P, and thus permit the pawl O to slip over and engage the next lower
tooth upon the ratchet N of the feed roller M, with the result that when the
operating lever C is released and the parts return to normal position the pawl (
will advance the ratchet N the space of one tooth and turn the feed roller Ma
corresponding distance.
The platen roller F, which is also preferably a rubber faced roller, bears upon
the roller M when the parts are in operative position, as in Figs. 1, 2 and 3, and
the strip or sheet of paper is passed between them, so that when the roller M is
actuated at each operation of the machine in the manner and by the means just
described the paper will be slightly advanced to bring a fresh surface to the
printing line. The roller F is mounted in a frame which is supported by and
adapted to be swung forwardly and backwardly upon and slid longitudinally of a
rod A' which is fixed at opposite ends in rearwardly projecting ears upon the upper
ends of the fixed side frames JK this rocking and longitudinal moving frame
constituting the paper carriage of the machine. The rod A¹ is best shown in
Figs. 3, 4 and 5, being also shown in section in Fig. 7, and the opposite ends of it,
where it is fixed in the frames J K in Figs. 1, 2 and 6. The rocking fraine or
paper carriage in which the roller F is supported is best shown in Figs. 3, 4 and 5,
but also in Figs. 1, 2, 6 and 7. It consists of a cross bar B Figs. 3 and 5
provided at its opposite ends with upturned arms in which the opposite ends of
the spindle of the roller F are journaled, and provided upon opposite sides of its
middle with downwardly extending supporting arms D' whose lower ends surround
and fit the rod A', so as to freely turn and slide longitudinally upon the latter.
The paper carriage is thus free to be swung forward and backward so as to bring
the roller F into contact with the roller M, as in Fig. 2, or to carry it upward and
backward and away from said roller as in Figs. 5, 6 and 7, and is also free to be
slid longitudinally of the rod A' for a purpose hereafter explained. The right
hand side arm C₁ of this paper carriage is prolonged a considerable distance beyond
the roller F to form a handle E by means of which the frame may be rocked
forward and backward and moved along the rod A¹ as hereafter described.
Firmly secured at its opposite ends in the upper ends of the side arms C' (above
the journals of the spindle of the roller F) is a rod F¹ to the under side of which
is rigidly secured a curved paper guide G₁ extending forward over and fitting
against the upper surface of the roller F, the forward edge of this guide being cut
out as shown in Fig. 4 to form forwardly extending fingers G" with wide spaces
between them. To further guide the sheet of paper around the roller F there are
provided curved springs H₁ Figs. 4 and 5, which are hooked at their upper rear
ends over the rod F¹ (in grooves therein) and extend thence through holes in the
curved guide plate Gi and thence forward beneath the fingers G₁ of the latter
plate, and around the forward side of the roller F and thence rearward beneath the
same, and are secured at their lower rear ends to the lower paper guide I' as best
seen in Fig. 7 the latter consisting of a sheet metal strip extending from side to

page_text: side of the paper carriage, and secured at its forward edge upon lugs J upon the
upper surface of the cross bar B¹ of said carriage, as shown in Figs. 3, 5 and 7. The
rear edge of this plate I¹ is curved downwardly as shown, and near its middle is
provided with a depending guide way K' for a narrow strip of paper, Figs. 3
and .6, for a purpose hereafter explained.
At its right hand end the spindle of the roller F projects through the side
arm of the paper carriage and has secured upon it a milled thumb piece L', by
means of which the roller may be readily turned in either direction when thrown
backward away from the roller M, as in Figs. 6 and 7. In such position the sheet
of paper upon which the printing is to be done is inserted by placing its upper
forward edge upon the lower guide plate I', Fig. 7, and pressing it forward until it
catches between the under surface of the roller F and the spring guides H. Upon
then turning the roller F forward by means of the thumb piece L' at its right
hand end, the sheet of paper will be drawn forward and upward and carried thence
rearward beneath the upper guide G, and pass thence outward beneath the rear
edge of said guide as it is advanced. When the sheet of paper has been thus
inserted in proper position the paper carriage will be thrown forward and the
roller F allowed to rest upon the roller M as in Figs. 1, 2, 3 and 4, whereupon the
movement of the roller M at each operation of the machine, as heretofore explained,
will cause the roller F to turn with it and advance the sheet of paper. The several
sections of the roller M contact with the roller F in the spaces intermediate the
spring guides H¹ passing around the roller F, as will appear from Figs. 4 and 5.
From the foregoing description it will be understood that upon inserting a sheet
of paper in the manner described and sliding the paper carriage to extreme right
hand position, the left hand end of the roller F and left hand edge of the paper
will be brought opposite the printing point, and that with the parts in such
position a column of figures at the left hand side of the sheet of the paper may be
printed thereon by consecutive operations of the machine. It will be further
understood that after such a column has been printed, the paper carriage may be
thrown backward to carry the roller F away from the roller M, and the roller F
be then turned backward by means of the thumb piece L' at its right hand end
until the head of the printed column is brought back to the printing line, and that
upon then sliding the paper carriage to the left the proper distance. and throwing
it forward again and permitting the roller F to rest upon the roller M, the parts
will be in a position to print a second column of figures upon the sheet of paper,
immediately at the right of the first column; and that by repeating this manipula-
tion a series of columns of figures may in this manner be printed side by side upon
the sheet of paper.
The lower ends of the fingers G₁ of the upper paper guide G1, Figs. 4 and 5, are
in about the horizontal printing line along the roller F, and they serve to indicate
when the roller has been turned backward far enough to bring the sheet of paper
to proper position to cause the first amount in the second and succeeding columns
to be printed in the same horizontal line as the first amount in the first column,
so that the heads of the several columns may all stand in horizontal line.
For the purpose of enabling the paper carriage to be readily adjusted laterally to
proper positions for printing the respective columns, and for locking it in its
different adjusted positions while the columns are being printed, and while the
carriage is swung backward and forward, the following means are provided. As
indicated by the spaces separated from each other by the spring guides H¹ in
Figs. 4 and 5, the arrangement of parts shown in the drawings is intended to
permit the printing of five columns side by side upon the sheet of paper; and the
rod A, as shown in those views and also in Fig. 3, is provided with five circum-
ferential grooves M¹ which are adapted to co-operate with a catch upon the sliding
paper carriage. As shown in Figs. 3, and 7 the catch which co-operates with these
grooves consists of a short arm N₁ which is fastened upon the left hand end of a
rock shaft which is journaled at one end in one of the supporting arms D¹
of the paper carriage and at its opposite end in a rearward extension P₁ of one of
C

page_text: the side arms C₁ of said carriage, and has fastened upon it at its latter end an
upwardly extending lever Q' having its upper end shaped to form a finger piece in
convenient relation to the upper end of the handle for the two to be grasped
between the thumb and forefinger of the operator. A coiled spring surrounding
the rock shaft O', and secured at one end to said shaft and at its opposite end to
a direction to engage
the bearing P¹ of the shaft presses the latter in
The catch may be
the catch N with the grooves M in the rod A¹.
disengaged from the grooves in the rod by pressing the upper end of the lever Q1
toward the handle E', which is conveniently done by grasping the two between the
thumb and forefinger and simply squeezing them together. The operator will
grasp the handle E of the paper carriage and the upper end of the lever Q', and
swing the paper carriage backward to the position shown in Figs. 6 and 7. He
will then press the lever Q₁ toward the handle Et far enough to disengage the
catch N¹ from the extreme right hand groove M¹ in the rod A¹ (the left hand
groove in Fig. 3) and then slide the paper carriage toward the left, releasing the
lever Q and continuing the movement of the carriage toward the left until the
catch N springs into the next groove M in the rod A¹. This will arrest the paper
carriage and lock it in proper position for the printing of the second column. The
operator will then turn the roller F backward (by means of the thumb piece L¹)
until the sheet of paper is brought into proper position to begin printing at the
head of the second column, and will then swing the paper carriage forward to
normal position and resume the operation of the machine.
In this manner and by these means the printing of the several columns side by
side and at equal distances from each other may be readily effected without the
exercise of any great care or skill on the part of the operator in adjusting the
parts for such purpose.
To further guard against and positively prevent the printing of the columns
upon the paper sheet except in proper relation to each other the following locking
device is provided, which prevents the paper carriage being slid laterally except
when swung backward to the position shewn in Figs. 6 and 7, and which prevents
its being swung forward again to normal position except when its lateral adjust-
ment is such that it is in proper position for the printing of a column of figures
upon the sheet of paper. The left hand one of the two supporting arms 11 of the
paper carriage in Fig. 3 is extended downwardly below the rod A', and when
the paper carriage is swung backward to the position shown in Fig. 7 this exten-
sion of the arm D contacts with a fixed rod Ri and limits the backward movement
of the parts. The under side of the rod A' is cut away or grooved longitudinally,
as at Si in Fig. 7, and the extension of the arm 1 above mentioned has secured to
it a plate T Figs. 3 and 7, whose upper end fits in said groove S₁ when the paper
carriage is in rearward position, and travels in said groove as the carriage is moved
laterally. When the carriage is thrown forward to normal position the upper
end of this plate T passes out of the groove in the shaft A' and enters one of the
circumferential grooves in said rod. When the paper carriage is in forward
position, therefore, the engagement of this plate T with the circumferential
groove M in the rod A will prevent lateral movement of the carriage, and it
will be necessary to swing the carriage rearward and carry the plate T¹ out of the
circumferential groove and into line with the longitudinal groove, before the
carriage can be moved laterally. Likewise, when the carriage is moved laterally
after being thus swung rearward, the plate T¹ must be brought into line with
another one of the circumferential grooves in the rod A¹ before the carriage can
be thrown forward again to normal position. The co-operation of this plate T
with the circumferential and longitudinal grooves in the rod A' thus prevents the
paper carriage being moved laterally while in forward position, and when swung
rearward it prevents its being swung forward again until it is in proper position
for the printing of a column of figures.
The remaining feature of the invention relates to the provision of an automati
alarm or signalling device, to indicate the approach of the printed column to the

page_text: normal
lower end of the sheet of paper, so that the operator may not inadvertently continue
the operation of the machine beyond the proper point for the lower end of the
column, and by means of which, also, uniformity in the lengths of the several
columns may be attained without careful watching on the part of the operator and
consequent interference with his rapid operation of the machine this signalling
device serving a similar purpose in respect to the lengths of the columns of figures
that the signalling device upon the ordinary typewriter serves in respect to the
lengths of the lines. Journaled at its opposite ends in the side frames JK, below
and in front of the shaft L of the feed roller M, is a shaft A2, Figs. 1 to 7. Rigidly
secured to the extreme right hand end of the shaft A3 at the outer side of the
frame J is an upwardly and rearwardly projecting arm B2, Figs. 1, 3, 4 and 5
and 6, while rigidly secured to the extreme left hand end of the shaft A2, outside
the frame K, is a corresponding upwardly and rearwardly projecting arm C,
Figs. 2, 3, 4 and 5. The upper rear ends of these two arms B2, C3, are rigidly
connected by a transverse bar Da, Fig. 3, so that the two side arms and the con-
necting bar I constitute a pivoted or swinging frame having the rock shaft A³
for its fulcrum or pivot. A coiled spring E surrounding the shaft A² at its left
hand end, and connected at one end to said shaft and at its opposite end to the
side frame K, presses the swinging frame upward and yieldingly holds it in the
position shown in Figs. 1, 2 and 3. As indicated in Fig. and clearly shown in
Fig. 6, the right hand side arm B of this swinging frame is forked to form a
second arm which has pivoted to its rear end a striker lever G yieldingly held
in normal position by a coiled spring H2 and adapted to be actuated by means
hereafter described to sound a gong or signal bell 12 which is carried by the lower
end of an arm or rod Js fixed at its upper end in the side frame J., Loosely
mounted upon a stud projecting from the arm B2 (and hereafter more fully
described) is a gear wheel K2, Fig. 1, which meshes with a pinion L2 fast upon
the end of the feed roller shaft L, when the swinging frame is in its upper
position, and which becomes disengaged from said pinion when said frame is
depressed in the manner hereinafter described. The normal engagement of the
gear K with the pinion L2 on the feed roller shaft causes the gear K³ to be turned
slightly at each operation of the machine. Now, the gear K carries a trip device
adapted to co-operate with the forwardly projecting arm M² of the gong striker G³,
to retract said striker and release it and permit its spring H to throw it against the
gong and sound the latter. As hereafter described this trip for the gong striker
is adjustable around the gear K3 and the gear is provided with an indicator or dial
as seen in Fig. 1. In the present instance the gear has 100 teeth, and the indicator
or dial 100 divisions, and at each operation of the machine the gear wheel is
advanced the space of one tooth. By adjusting the trip around the gear wheel, to
different points on the dial, it may be caused to engage the gong striker at different
predetermined points in the forward movement of the gear wheel from initial
position, with the result that the trip may be adjusted to sound the gong at the
end of any predetermined number of operations of the machine; after which, by
depressing the swinging frame which carries the gear wheel the latter may be
disengaged from the pinion L2 of the feed roller shaft and turned backward to
initial position. To illustrate, if it be desired to print columns of figures having
fifty amounts in each column the trip will be set at such a point upon the gear
wheel that it will require fifty forward movements of the latter from initial position
to sound the gong. The operator will, therefore, continue his operation of the
machine until the gong is sounded, which will occur at the end of the fiftieth
operation of the machine, and will then shift the paper carriage and paper to
position for the next column, in the manner heretofore described, and reset the
gear wheel to initial position. He will then resume his operation of the machine
and continue it until the gong is again sounded, which will occur at the end of
the hundredth (or second fiftieth) operation of the machine; and so on until the
sheet of paper is filled with columns of equal length, each containing fifty amounts.
Having now explained in a general way the purpose and operation of the

page_text: signalling device, I will proceed to a more detailed description of the construction
and mode of operation. The arm B² is provided with a hole N2, Fig. 6; in which
fits one end of a stud or small stud shaft 0%, as clearly shown in the enlarged
detailed view in Fig. 9. The shaft 03 is provided with an enlargement or collar P³
fitting against the outer side of the arm B of the swinging frame, and the reduced
portion of the shaft which passes through the hole in said arm is threaded and
has screwed upon its end a nut Qs, by means of which the shaft 02 is rigidly
secured in the arm B³, a washer R³ being interposed between the nut Q2 and arm B
The gear wheel K2 is loosely mounted upon the shaft 02, and is provided upon
its outer side with an extended hub or sleeve S2 surrounding the shaft 02, and
upon its opposite side it is provided with a cylindrical casing T whose end is
closed by a cap or disc U³. The gear wheel is held in position upon the shaft O
Ly a disc V secured to the front end of the shaft (3 by means of a screw Ws, said
disc co-operating for that purpose with the front end of the hub or sleeve S2 of the
gear wheel. Located within the casing Ts upon the opposite side of the gear wheel
is a coiled spring X whose inner end is secured to the shaft 02 and whose outer
end is secured to a split friction ring Y tightly fitted within the casing T, as
shown in Figs. 8 and 9. As the gear wheel K2 is turned forward upon the shaft L
by the operation of the machine, in the direction of the arrow in Fig. 8, it will
wind up the spring X and put it under tension, so that when the gear wheel is
released and left free to turn backward said spring will serve to turn it in that
direction. The operation of the parts in this respect would be the same if the
outer end of the spring were secured directly to the gear or its casing T, the
purpose of connecting it with said casing by means of the split friction ring Y
being to furnish a connection with the gear wheel which will yield when the gear
wheel is turned beyond a certain limit and prevent breaking of the spring.
The gear wheel K³ is provided upon its inner face with a projecting stud A
Fig. 8, which is adapted to co-operate with a stop 133 located upon the side arm B
of the swinging frame, as shown in Fig. 6 and in dotted lines in Fig. 8. When
the gear wheel is in initial or zero position its stud A³ is in contact with the rear
end of the stop B³ and the latter serves to limit the backward movement of the
gear wheel under the stress of the spring X2 As the machine is operated and the
gear wheel turned forward from initial position its stud A³ is carried away from
the stop B³. When the gong is sounded, at the end of a column, and the swinging
frame is depressed and the gear wheel K2 thereby disengaged from the pinion L
on the feed roller shaft; as heretofore explained, the spring X, will turn the gear
wheel backward until its stud A³ contacts with the stop 13, thereby arresting the
gear wheel in initial position. The stop B3 upon the side arm of the swinging
frame might be simply a rigid projection on such side arm, but in the present
instance it consists of a short lever pivoted upon said arm and yieldingly held in
normal position by a spring C3, Figs. 6 and 8. This construction and arrangement
permits the stop to yield and allow the stud A³ to pass it in a forward direction if
the gear wheel should be turned forward more than a complete revolution, as might
be the case in the printing of long columns upon a long sheet of paper. For the
purpose of printing columns of anything less than 100 numbers, however, a rigid
projection upon the side arm of the swinging frame would serve the same purpose
as the yielding stop, although the latter is convenient in assembling the parts in
that it enables the spring within the casing of the gear wheel to be readily put
under tension by initially turning forward the gear wheel a revolution or two.
The adjustable trip carried by the gear wheel consists of a pointer D³, Figs. 1
and 9, whose extreme outer end projects beyond the periphery of the gear wheel
and co-operates with the arm M2 of the striker lever. At its inner end the
pointer D³ is secured to or formed integral with a sleeve E³ surrounding the gear
wheel hub or sleeve S, and enlarged at its forward end at F3 to form a housing
within which is confined a coiled spring G³, said spring bearing at its outer end
against the disc V8 secured to the front end of the shaft 02, and at its inner end
against the internal annular shoulder of the housing F³. The spring G³ presses
"

page_text: the sleeve E³ inwardly and holds the pointer D³ against the face of the gear K³, in
which position one or more short inwardly bent fingers H³ upon the outer end of
the pointer D³ fit between the teeth of the gear wheel and thereby lock the pointer
to the wheel. The pointer may be disengaged from the wheel by pulling the
sleeve E³ outwardly against the resistance of the spring G³, for which purpose the
outer surface of the housing F3 of the sleeve is roughened or milled as shown in
Figs. 3, 4 and 5. The pointer can then be turned around the gear wheel and re-
engaged therewith at any point desired. In Fig. 1 the gear wheel is shown in the
initial or normal position which it occupies at the beginning of the printing of a
column of figures, and the pointer or trip is set to such position that it will cause
the striker to sound the gong at the end of fifty operations of the machine. This
would be the adjustment of the parts for printing columns having fifty amounts.
If columns of twenty five numbers were to be printed the pointer would be turned
to the number 25 upon the dial of the gear wheel, while for columns of 75 numbers
it would be turned in the opposite direction to the number 75 upon the dial. In
this manner by first setting the pointer at any desired number upon the dial the
gong will be sounded at the end of that number of operations of the machine.
For the purpose of facilitating the release and resetting of the gear wheel and
its pointer or trip at the shifting of the paper carriage at the end of the printing of
one column of figures and preparatory to the printing of the next column, the
following means are provided for automatically disengaging the gear wheel from
the pinion of the feed roller shaft by the act of shifting the paper carriage laterally
from the position of one column to another. As seen in Fig. 3 the cross bar D
of the swinging frame which carries the gear wheel K is provided in its upper
edge with equi-distant notches or depressions J3 and the left hand supporting arm
I of the paper carriage in Fig. 3 is provided upon its rear side with a lug K³
adapted to co-operate with the bar D2, (See also Figs. 6 and 7.) When the paper
carriage is in any one of its proper adjusted positions this lug K³ upon the arm D₁
will stand in line with one of the notches J3 in the bar D. In Fig. 3 it is opposite
the third notch from the left in that view. If the paper carriage be now swung
backward to the position shown in Figs. 6 or 7 the lug K will simply enter the
notch in the bar D and not move the latter, but when, after being swung back,
the paper carriage is slid laterally toward position for the printing of the next
column the lug K³, riding over the inclined side of the notch J³ in which it had
been resting, will depress the bar D2 and thereby swing downward the frame of
which said bar forms a part and which carries the gear wheel K*. This depression
of the swinging frame will disengage the gear K2 from the pinion L of the feed
roller shaft, whereupon the gear wheel will be immediately turned backward to
normal position by its spring X, as heretofore explained.
In the manner and by the means above described, therefore, the gear wheel and
trip for the gong striker are automatically released and reset to normal position
at each shifting of the paper carriage from one printing position to another, so
that having first set the trip at any given number upon the dial of the gear wheel
the operator need pay no further attention to the adjustment of the signalling
device so long as he desires to continue printing columns containing that number of
amounts in each column. When he reaches the end of the first column the gong
will be sounded, and he will swing the paper carriage backward, shift it laterally
to position for the next column, turn the sheet of paper backward to bring the head
of the column to printing position and then swing the paper carriage forward to
normal position, and proceed with the operation of the machine until a second
sounding of the gong notifies him that the end of the second column has been
reached; whereupon he will repeat the above described manipulation until the
sheet of paper has been filled with columns of uniform length.
The employment of this new printing attachment, for printing parallel columns
upon wide sheets of paper, does not prevent the use of the machine for printing
single columns upon long and narrow strips of paper, as heretofore. In Fig. 3

page_text: there is shown in dotted lines a roll of paper strip supported in the framework,
and the strip led thence upward through the paper guide K' heretofore referred
to, whence it would pass forward over the paper guide I¹ (Figs. 6 and 7) and thence
upward around the platen roller F, as will be readily understood.
It will be understood from the description which has been given that the inven-
tion, in its broader scope, is not restricted to the details of construction and arrange-
ment of parts which have been illustrated and described, but consists in the new
combinations and modes of operation which have been set forth, and that while
preserving the essential features of the invention in this respect the details of con-
struction and arrangement may be widely varied. To illustrate, in Figs. 10 to 13
I have shown a modified construction and arrangement of the parts in which, the
swinging frame of the paper carriage, which carries the platen roller F, instead of
being mounted to swing upon and slide longitudinally of the round rod A', herefore
described, has the lower rear ends of its side arms C pivoted at a to ears b pro-
jecting upward from the opposite ends of a sliding frame A which frame is mounted
upon a fixed cross-bar 13 rigidly secured to arms or brackets c projecting rearwardly
from the upper ends of the side frames JK, this fixed cross bar occupying sub-
stantially the same position in the modified construction as does the rod A¹ in the
construction first described. The frame A is free to be slid longitudinally upon
the bar B, and to relieve the friction between the parts ball bearings are interposed
between them as shown at e, the cross bar being provided upon its front and rear
sides with longitudinal grooves, and the sliding frame A being provided with
coincident grooves, to accommodate the balls.
The sliding frame A' constitutes part of the paper carriage, and accommodates
the lateral adjustments of the latter for the printing of different columns, while
the backward and forward movements of the carriage, to carry the roller F into
and out of contact with the roller M, are permitted by the pivotting or hinging of
the side arms C¹ of the swinging frame to the ears 6 of the sliding frame A at a,
as before explained. So far as the mere hingeing of this swinging frame is con-
cerned its pivots a might be simply studs or screws projecting from the ears b but
in the present instance its right hand pivot a, Fig. 10, is a rock shaft, which, as
shown in Fig. 13, extends through the right hand side arm C', and through the
adjacent ear upon the sliding frame A, and thence onward to a point adjacent
the middle of the machine, where its left hand end is journaled in a bearing f
upon the rear side of the cross bar 13 of the swinging frame Figs. 12 and 13.
The fixed cross bar 14 has secured to or formed integral with its upper side a
longitudinal rib g, which rib, as shown in Fig. 13, is provided at intervals with
transverse notches h, these notches corresponding in purpose and function to the
circumferential grooves M of the rod A' in the main construction Figs. 3 and 5,
and occupying a similar position relatively to the other parts. As shown in
Figs. 12 and 13 the cross bar 13 of the swinging frame has rigidly secured to it
adjacent the left hand end of the rock shaft a (right hand end in Fig. 13) a sector
plate which is adapted to travel back and forth in the respective notches h in the
rib when brought into line therewith and the frame then swung backward and
forward upon its pivotal supports a. As shown in Fig. 12 this plate i is of such
size and so located that when the swinging frame is in forward position the plate
will rest in one of the notches h in the rib g, and prevent the paper carriage being
slid longitudinally of the bar B. When the swinging frame is swung backward to
its limit of movement, however, this locking plate will be carried forward and
out of the notch in which it has been resting, so that the paper carriage is then
free, so far as the co-operation of this plate with the notches h in the rib is con-
cerned, to be slid along the bar B', but cannot be swung forward to normal position
again except when the locking plate i is brought into line with one of the notches i
in the rib.
The paper carriage is, however, provided with an additional latch or locking
device controlling its lateral adiustments, of which the rock shaft a. Fig. 1B3.

page_text: heretofore referred to, forms a part. As shown in Figs. 10 and 13 this rock shaft
has secured upon its extreme right hand end (left hand end in Fig. 13) an up-
wardly extending arm or handle C, corresponding to the arm or handle Qin
the main construction. The hub of this arm is provided with a projecting
shoulder, Fig. 10, which co-operates with a stop upon the side arm C₁ of the
swinging frame, to limit the backward movement of the arm and rock shaft a
under the stress of the coiled spring k surrounding the rock shaft, as shown in
Fig. 13.
As shown in Figs. 12 and 13 the rock shaft has secured upon its
opposite end an arm / whose outer end is of substantially the same thickness and
stants in line with the locking plate i heretofore described. When the handle C
and connected parts are in normal position, and the swinging frame is swung
backward to its limit of movement the outer end of the arm will enter the
rear side of the notch in the rib y before the rear edge of the locking plate i is
carried entirely out of such notch, with the result that the sliding paper carriage
is not released from the notch by merely swinging the frame backward to its limit
of movement, being locked by the arm before it is entirely released by the plate i.
To then release the paper carriage and permit it to be slid longitudinally of the
bar B it is necessary to press the upper end of the handle C upward or forward
toward the finger piece E of the side arm C of the swinging frame, as in the case
of the arm Q and its latch in the main construction. When the arm is thus
pressed toward the arm C₁ the shaft a will be rocked and its arm thrown rear-
ward out of the notch in the rib g, and thereby release the paper carriage and
fermit it to be slid along the bar 13 to the position for printing the next column.
In adjusting the paper carriage, in the ordinary operation of the machine, the
frame carrying the platen roller will be first swung backward to its limit
of movement, and the finger piece of the arm C pressed toward the
then
of the swinging frame, and
finger piece E of the side arm
as the paper carriage has been slid laterally far enough to prevent
re-engagement of the locking arm with the notch in the rib g the arm 'C' will
be released, and the spring surrounding the rock shaft a permitted to press the
parts back toward normal position. The action of the spring will press the arm
against the rear side of the rib g, and it will slide along the latter, as the paper
carriage is moved, until it comes opposite the next notch in the rib g, whereupon
it will spring into such notch and thereby arrest the paper carriage in position
for printing the next column, and the frame carrying the platen roller will then
be swung forward to normal position and the operation of the machine be resumed.
The arm C and the latch controlled by it therefore serve as a means for readily
determining the positions of the paper carriage.
soonl
as
The operation of the signalling device, and its co-operation with the paper
carriage whereby the trip is automatically reset to normal position at the shifting
of the paper carriage from one printing position to another, are substantially the
same as in the construction heretofore described, the only differences being in
the positions of the parts, the swinging frame which carries the gear wheel K
extending forward from its pivotal support, instead of rearward, and the stop 133
which arrests the gear wheel in initial position when it has been released by its
disengagement from the pinion L2 of the feed roller being located at the under
side, instead of at the upper side, of the wheel, as shown in Fig. 10. The notched
cross bar of the swinging frame carrying this gear wheel, which corresponds to
the bar D of the main construction (Fig. 3) is shown at D in Fig. 12, where it
will be seen that it co-operates with an arm E secured to and depending from
the forward side of the sliding frame A' and engaging the rear edge of the bar D.
This bar D is secured at its opposite ends to the upper ends of two arms D5 fastened
at their lower ends to a rock-shaft D6, to whose extreme right hand end the arm B²
carrying the gear wheel K² is secured. When the sliding frame A4 is moved
longitudinally of the bar D', in adjusting the paper carriage from one printing
position to another, the lower end of the arm engaging the rear-edge of the

page_text: bar D will press the latter forward and thereby rock the shaft D and throw
the arm B forward and downward, and disengage the gear wheel K² from the
pinion L³, as. will be readily understood.
At the left hand side of the machine, Fig. 11, the arrangement of the parts
for actuating the feed roller M is slightly but not materially different from that
shown in the main construction and heretofore described. The rock shaft S which
is actuated by the contact of the stud Y (on the lever. X Fig. 2) has secured
upon its extreme left hand end a forwardly extending arm F to which is pivoted
the lower end of a link G whose upper end is pivoted to the pawl carrier P carrying.
the pawl O co-operating with the ratchet N on the shaft of the feed roller M.
The arm F is provided with two holes a¹, 61, connected by a slot c', and the lower
end of the link G' carries a stud d', which fits in and co-operates with the holes a' b¹
and may be shifted from one to the other. When engaged with the hole b', which
is nearer the fulcrum of the arm or lever F, a less throw will be given the link G⭑
and the pawl-carrier and pawl than when the lower end of the link is swung
forward and its stud engaged with the hole a'. The adjustment of the parts is
such that when engaged with the hole b₁, as in Fig. 11, the pawl O will slip back-
ward over one tooth of the ratchet N and advance the latter the space of one tooth,
at each operation of the machine, while when the lower end of the link is swung
forward and its stud engaged with the hole al, and the pawl will be given, twice
as much throw at each operation of the machine and the feed roller and paper
therefore advanced twice as far as under the first mentioned adjustment. By
this means the machino may be adjusted to print the items close together in
cach column, or farther apart, as may be desired.
In addition to the paper guides about the platen roller F, I have provided in
the modified construction a pressure roller H+ bearing upon the upper side of
the platen roller F. The spindle of this roller is mounted at its opposite ends in the
front ends of levers I pivoted to the side arms C₁ of the swinging frame, and
engaged at their rear ends by springs J, Figs. 10 and 11, which serve to press
the roller H+ into contact with the roller F. The lever I at the left hand side
of the machine, Fig. 11, is provided with three arms, the upper vertically ex-
tending one of which K forms a handle by which the roller I may be lifted out
of contact with the roller F. The roller H is composed of sections which bear
upon the roller F between the spring guides passing around the latter, as will
be readily understood without illustration.
While I have shown carriages of certain forms for supporting the platen it
will be evident that the construction may be changed, especially if a different
character of platen is employed, and the carriage or the platen thereof of course
may be mounted to swing or slide back and forth to and from the type in any
suitable manner.
If desired instead of a long roller M, as shown, the platen may be turned by
contact with a single disc or pulley at the centre of the shaft L, or any other
suitable gear or means from said shaft or other operating part of the machine.
