Improvements in Cash Registers and Check Printers and Tills.
We, THE NATIONAL CASH REGISTER COMPANY LIMITED, of 356 Strand, London,
W.C., Manufacturers, do hereby declare the nature of this invention, a communication
to us from abroad by The National Cash Register Company, of Dayton, Ohio,
United States of America, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement ;-
In its general construction and mode of operation our present machine is similar to
that shown and described in Patent No. 13,832, dated June 23, 1896; and our
invention consists in certain improvements based upon that machine, but applicable
to others as well, which will be hereafter fully described and pointed out in the
claims.

Our present machine, like the aforesaid prior one, is designed to indicate to the
customer and bystanders the amount of each sale, to add into one common total
the amount of all sales made and registered, to print. the amount of each sale upon
the paper record strip carried within the machine, and also upon a paper check or
ticket strip, the printed portion of which, constituting the check or ticket, is
projected from the machine at each operation and severed from the strip; and also
In addition,
preferably, to date and consecutively number such checks or tickets.
our present machine also prints the date and consecutive number of each transaction
upon the record strip before referred to, such dates and numbers being printed
opposite the amounts representing the respective sales. The improvements forming
the subject matter of our present invention relate chiefly to the printing attachment

page_text: and to means intermediate the operating keys or levers and the registering
mechanism, by which such mechanism is actuated and by which also the type
wheels of the printing attachment are set at each operation.
In the prior machine there were employed three sets of cash keys, each containing
nine keys, and representing respectively units of cents, tens of cents and units of
dollars; but in the aforesaid application it was stated that a large number of sets
of keys might be employed to advantage, under the plan of construction and mode
of operation described, and accordingly in our present machine we employ, and will
illustrate in the drawings and describe in the specification, six sets or groups of cash
keys, representing respectively units and tens of cents, and units, tens, hundreds and
thousands of dollars, so that at a single operation of the machine any amount from
one cent to $9999.99 may be indicated, registered and printed, as hereafter
described.
.
The operating keys or levers by or through which the registering mechanism is
actuated and the type wheels set consist of the levers A fulcrumed on the shaft B
and resting at their rear ends on a cross bar C of the frame work in the lower ends
of vertical slots in a guide plate D secured to the rear side of the frame work.
Mounted above the front ends of the levers A, in the inclined cross-plate E of the
frame work, are the setting keys F, consisting of the straight stems resting at their
lower ends upon the front ends of the respective levers A or adapted to be pressed
downward into contact therewith, and carrying at their upper ends numbered
buttons representing their respective values. The levers A are arranged very closely
together side by side, and to accommodate the nine setting keys and their numbered
buttons to the narrow space occupied by each set of levers the keys of each set are
arranged in an inclined double row in the plate E of the frame work, so that the
lower end of each one of the key stems may rest upon or immediately above one of
the levers A. In addition to the several sets of cash keys there are the four special
keys G, each co-operating with a special lever A, as described in the former
application.
Arranged in guide plates above the rear ends of the levers A are the vertical
indicator rods H, one resting upon or supported immediately above each lever.
Their uppers ends are so bent as to bring the indicators I of each group into compact
order one behind another, as shown. The rods Hare provided upon their rear sides
with shoulders or projections J which co-operate in the well known manner with the
pivoted supporting bar or wing K to temporarily support the exposed indicators at
the end of each operation of the machine.
Pivoted to the side of each lever A near its rear end is the lower end of the
vertical lifter arm or plate L. These lifters are provided upon their forward sides
or edges with the fingers M, which fingers with the recesses or mouths formed by
them, co-operate with the rear transverse rods N of the rocking registering frames
mounted upon the shaft O, each frame consisting of two end plates or arms P hung
at their forward ends upon the shaft O, and the cross rod N and a cross bar
connecting said plates. There is one of these rocking registering frames for each set
of keys, and the nine lifters L of each set are all arranged to co-operate with the
single rod N of the frame above them. The fingers M of the lifters of each set are
arranged at graduated distances from the rod N with which they co-operate, so that
the uniforin vertical movements given said lifters will move their co-operating
registering frame different degrees. The lifters L are provided upon their rear
sides or edges with the cam shoulders R6 adapted to co-operate with the cross bar S
of the frame work. When any lifter L is raised by the depression of the front end
of its connected lever A its flanges M passes upward between the rod N and the
bar Qof its registering frame and the engagement of the cam shoulder Re upon its
rear side with the lower forward edge of the cross bar S throws the lifter forward and
causes its recess or mouth above the finger M to embrace the rod N.
The rear
edge of the lifter, beneath its shoulder R, is of such shape that in its further
upward movement the lifter may accommodate itself to the movement of the rod N
in the arc of a circle concentric to its pivot 0, and the shape of the finger M of the

page_text: lifter and of the rear side or edge of the cross bar Q of the registering frame are
such that when the finger M. fully enters the space between said bar and the rod N
and begins to lift the registering frame it becomes locked or coupled thereto, so that
after the registering frame has been slightly moved by the lifter the two becomes
so connected that neither can move independently of the other, with the result that
from the time the lifter begins to move the registering frame until the frame is
returned to substantially normal position the lifter and frame, and consequently the
lever A to which the lifter is pivoted at its lower end, are compelled to move
together.
Each of the registering frames has rigidly secured to it, directly or indirectly, one
of the gear toothed sectors T, Figures 1 and 3, by which the registering wheels are
actuated to register the values of the operated keys, the registering wheels being
mounted in a rocking frame U pivoted upon a transverse shaft V in such manner that
the pinions of the registering wheels may be thrown into and out of gear with the
respective sectors T to cause the movement of said sectors in one direction to he
transmitted to the registering wheels and said rocking movements of the frame U, to
gear and ungear the registering wheels and sectors, being effected by suitable cams
fast upon a rotary shaft W and co-operating with anti-friction rollers mounted upon
the ends of the rearwardly projecting arms of the frame U. The transfers between
the several registering wheels are also effected by cams fast upon said shaft W and
actuating the transfer pawls of the several wheels through the medium of levers X
pivoted upon the shaft V above referred to. There being nothing novel in this part
of the mechanism it need not be here described more at length.
The levers A and their lifters L are operated by power transmitted to them through
the medium of the universal bar or frame Y overlying the entire lot of levers A in
rear of their fulcrum shaft B, and hung at its opposite forward corners to the side
frames of the machine so that its rear edge is free to rise and fall. By the means
described in the aforesaid application, which means is illustrated in the accompanying
drawings, but which need not be here described in detail, the rear ends of the
levers A become attached or coupled to the rear edge of the universal bar or frame Y
whenever the front ends of the levers are slightly depressed, as may be done by
pushing downward the setting keys F. By means hereafter described the rear edge
of the bar Y is given a definite movement upward and downward at each operation
of the machine, moving from its normal position shown in the drawings upward to
its limit of movement, and then downward to a point below the normal position
shown, so as to release the keys which are attached to and have been carried upward
by it, at the very end of the operation, after which it moves upward slightly to its
normal position of rest.
From what has been heretofore said about the connection of the lifters with the
registering frames, and the necessity for their moving together after once becoming
connected, it follows that the positive movement given by the bar Y to the operated
levers A and lifters, positively returning them to their normal position at the end of
each operation, will also serve to positively return the registering frames to their
normal position, the operated lifters becoming uncoupled or disconnected from the
frames as the latter reach such position. The registering frames themselves are
therefore thus positively moved in both directions, from normal position and back to
it. This enables us to dispense with the resetting springs heretofore employed for
yieldingly holding the registering frames in and returning them to normal position.
In prior machines of this character where the levers A were operated directly by the
hand of the operator depressing their front ends to their full limit of movement,
there was no positive means provided for resetting the levers and the lifters and
registering frames, and the gravity of the bar Y and the stress of the springs
connected to the registering frames were depended upon for that purpose.
machines of the aforesaid patent, while positive means was there for the first time
employed to reset the parts, and consequently the springs were not needed to return
the registering frames to normal position, yet after they had been returned thereto
and the lifters disconnected from them some means was required for holding them in
In

page_text: normal position and preventing accidental displacement of them therefrom, and for
this purpose the resetting springs connected to the registering frames were shown in
the drawings of the aforesaid prior patent. Where, however, as in our present
inachine a large number of sets of keys are employed, and a correspondingly large
number of resetting springs for the registering frames would be required, it follows
that when any considerable number of said frames were actuated at any given
operation of the machine the resistance of their springs which would have to be
overcome would add materially to the load of the machine. In our present machine,
therefore, while dispensing with the resetting springs and relying upon the positive
movement of the parts to return the frames to normal position, we have provided
means for effectually preventing their accidental displacement therefrom, and for
positively holding or locking them in said position, except when they are to be
actuated in the operation of the machine. In the first place we have provided means
common to all of the frames for locking them in normal position so long as the
operating handle and driving mechanism of the machine are in their normal position
of rest. This lock, however, is released at the beginning of each operation of the
machine, so that so far as it is concerned the registering frames are then all free to
be moved. To still further lock them, therefore, and to permit only those to be
moved which correspond to the groups of keys in which levers A have been set and
connected to the universal bar Y, so that only those are free to move which are to be
actually employed at that operation of the machine, we provide a second set of
locking devices, there being one locking device for each registering frame and such
locking device being controlled by the keys or lifters co-operating with such frame,
in such manner that unless the Jocking device be released by or consequent upon the
operation of some key in that set the frame will remain locked. These two locks
may now be described.
Mounted in bearings A¹ upon the under side of a cross bar R of the framework,
against whose forward side the upper rear ends of the sectors T normally rest,
Figure 3, is a rocking shaft C¹ extending from a point slightly to the right of the
sectors to a point adjacent to the left side of the machine, Figure 1.
Fast upon
this rock-shaft are a series of forwardly projecting arms or fingers D¹, one beside each
sector T, and each sector has projecting from its side a stud or pin E¹ adapted to
co-operate with the adjacent arm D¹. In the normal position of the parts shown the
arms D¹ fit against the under side of the pins E¹ so that no one of the sectors can
be moved without depressing the adjacent arm D¹ and consequently rocking the
shaft C¹ and thereby depressing all of the arms. The shaft C is normally locked in
the position shown, thereby locking all of the sectors in normal position, by means
of an arm F1, Figures 1 and 3ª, upon the left hand end of the shaft and depending
therefrom and in the normal position of the parts resting at its lower end upon a
cam G' fast upon the rotary shaft W heretofore referred to. So long as this cam (¹
reinains immediately beneath the arm F¹ as in Figure 3ª the shaft C will be held
locked in normal position, but as soon as the cam is carried from under the arm Ft,
as it is at the beginning of each operation of the machine, and consequent rotation
of the shaft W, the shaft C¹ will be released and left free to yield and be rocked
forward by the forward movement of any one of the sectors T, as will be readily
understood. At the end of the operation of the machine, as the parts come to
normal position again, the cam G¹ will ride under the arm F¹ again and thereby
return the rock-shaft C¹ to normal position and throw up all of the arins D¹, which
latter will engage the pins E¹ on the sectors T and insure the complete resetting of
the latter, bringing them up against the bar R.
The second one of the two locking devices above referred to may be next described,
as follows.
Loosely mounted upon the rear cross rod N of each of the rocking
registering frames is a locking frame H¹, Figures 3, 4, and 5, consisting of
two end plates hung upon the rod N and a cross bar or plate rigidly connecting
them. The two end plates are extended upwardly and rearwardly and shaped to
form locking dogs I which rest against the forward face of the cross bar S of
the framework heretofore referred to. The forward face of this bar is provided

page_text: near its upper edge with a longitudinal recess or groove in which fit the rear ends
of the locking dogs I' when the parts are in normal position. A spring suitably
applied to the locking frame yieldingly press it rearward and causes the dogs to
engage the groove. In this instance the spring is confined in a bore in the cross
bar of the registering frame which carries the locking frame, and bears on
a sliding block or plunger J¹ fitted in the bore and pressing at its outer end
against the front edge of the cross bar of the locking fraine H, Figures I
and 4. Now it will be seen that when the parts are in their normal position
of rest with the dogs engaged in the groove in the bar S, the registering
frames will be locked from movement, so that it will be impossible to displace
any of the sectors T from normal position. Any one of the registering frames
may be unlocked, however, by swinging its locking frame H¹ upward and forward
until the dogs I of such locking frame are disengaged from the groove in the
bar S. Now, each of the lifters L is provided upon its front edge near its upper end
with a shoulder Z, which when the lifter is moved upward contacts with the cross bar
of the locking frame just as the finger M of the lifter passes upward in front of the
cross rod N of the registering frame, and forces the locking frame H¹ upward and
forward out of locking position just as the lifter begins to move the registering
frame. In this manner the operated lifter in any given set unlocks the registering frame
immediately before it begins to move such frame, while all of the registering frames
corresponding to sets of keys in which no key and lifter are operated remain locked.
In this manner and by this means all of the registering frames are normally locked
by their respective locking frames H¹, and at each operation of the machine those
franes which correspond to the sets containing the operated keys are automatically
unlocked to permit the operated lifters to actuate them.
By the employment of these locking devices, particularly those last described, we
ain enabled to dispense with the resetting springs for the registering frames and
thereby lighten the load of the machine, and at the same time insure the perfect
operation of all the parts. The form and arrangement of the locking devices may be
varied without departing from this feature of our invention, since so far as we am
aware we are the first in the art to devise an automatic locking device of any sort for
the purpose described.
For the purpose of preventing the simultaneous operation of two keys in the same
set, and the consequent inaccuracy in registration which would result therefrom, we
employ the locking devices shown in Figures 1, 3 and 4. As there shown there is a
transverse shaft K₁ extending from side to side of the machine above and slightly in
rear of the projected rear ends of the levers A, in rear of the vertical guide plate D.
Strung upon this shaft are a series of circular locking disks L¹ having beveled or
rounded edges. There are eight of these disks for each set of levers, one disk
overlying the space between each two adjacent levers, with the lower forward portion
of its beveled edge fitting between the ends of the two levers. The disks are slightly
wider than the space between the keys, so that if it be attempted to simultaneously
lift the rear ends of any two keys in the same set the intermediate disk or disks L¹
will become wedged between such two keys and prevent their upward movement.
When, however, the rear end of a single key is lifted it will pass between the forward
edges of the two disks on either side of it and force them apart.
The means heretofore referred to for giving the universal bar Y its upward and
downward movements at each operation may be next described: The operating
handle M' is fast upon the end of a short shaft N1, Figures 2 and 4, which is
journaled in a bearing in the right hand side frame of the machine and which has
fast upon its inner end a gear 01 meshing with a gear P¹ which in turn meshes with
gear Q fast upon a shaft R. This shaft R¹ extends from a point about the middle
of the machine, Figure 1, to the right through and some distance beyond the right
and side frame, fitting at its outer end and in the outer side plate of the printing
attachment, hereafter described. Towards its left hand end it has a bearing in the
ight hand one of the two backwardly and forwardly extending frame plates S¹. Fast
pon this shaft R¹ at the left of the gear Q¹ is a cam disk T¹ which co-operates with

page_text: roller U¹ upon a stud projecting laterally from the front end of an arm X' fast upon
or formed integral with the universal bar Y. At each revolution of the operating
handle this cam T¹ will depress the front end of the arm X¹ and thereby lift the rear
edge of the bar Y. If a disk provided with a cam groove, in which the roller U'
might fit, were employed instead of the cam T', then the one cam would serve to
move the arm V' and bar Y" positively in both directions; and this substitution might
be readily made; but in constructing the present machine there was not convenient
room for the employment of a disk large enough to contain a proper cam groove for
the purpose, and we therefore provided the following additional means for giving the
bar Y a positive downward movement: Hung at its forward end upon the shaft R¹,
above described, is an arm or lever W' whose rear end carries a roller V' underlying
and fitting against a cam Y' fast upon the rotary shaft Wheretofore described.
This lever W is provided on its under edge near its rear end with a pendant
projection or swell which rests upon the rounded upper side of a lug upon the upper
surface of the bar Y. The shape of the cam Y¹ and adjustment of the parts are such
that the lever W₁ is snugly confined between the cam and the bar Y during the
entire upward and downward movement of the latter, so that the bar is positively
moved in both directions by the cams T¹ and Y¹, the same as though a disk containing
a cam groove were employed instead of the cam T', as heretofore suggested.
By means of a train of gears intermediate the gear Q' and the shaft W, Figure 4,
the latter is geared to the operating handle and is given a rotation at each operation
of the machine.
The remaining features of our invention relate to the printing attachment, by
which the numbers, dates and amounts of the various transactions are printed upon
the paper record and check strips and the latter projected from the machine and the
Journaled at its left hand end in the left
printed check or ticket severed from it.
hand one of the two frame plates $1, Figures 1, 3 and 3B, is a shaft A2 which extends
to the right through the second plate S', and on through the right hand side frame
of the machine. Fast upon this shaft near its left hand end is a gear B2, Figure 3B,
meshing with the left hand one of the six sectors T, while fast upon the extreme
right hand end of said shaft is the right hand one of the type wheels C2 bearing two
sets of type numbers, each representing the nine digits, the two sets of numbers
being separated at diametrically opposite sides of the wheel by dollar marks, which
latter normally stand at the printing points vertically above and below the axis of the
wheel. Mounted upon the shaft A2 are five concentric sleeves D2, each having fast
upon its left hand end a gear B2 meshing with one of the sectors T and upon its
extreme right hand end one of the six type wheels C2, each of which, excepting the
light hand one above described, bears two sets of type numbers each representing
the nine digits and separated by ciphers.
Owing to this gearing of the type wheels to the sectors and downward and forward
movement of any of the sectors at a given operation of the machine, to register the
values of the operated keys in the manner before explained, will also operate to turn
the corresponding type wheels and cause them to bring to the printing points the
numbers representing the values of the operated keys, and while such numbers
are at the printing points the paper strips are forced against the type by platens
hereafter described and the printing thereby effected, after which, during the latter
part of the operation, the type wheels are returned with the sectors to normal
position.
Immediately at the left of the type wheels C2 adjacent the side frame of the
machine, is a type wheel A5 which is fast upon the right hand end of a short
sleeve A° surrounding the sleeves D2 and extending to the left through the side
frame of the machine. Secured upon its left hand end is a beveled gear B.
Figures 1, 3 and 4, which meshes with a beveled pinion C5 fast upon the rear end
of a forwardly extending shaft D³ whose front end projects outside the casing of the
machine and has secured upon it an index disk E5 co-operating with a fixed
pointer and provided with a milled thumb piece by which the shaft can be turned.
The type wheel A5 bears upon its periphery two diametrically opposite duplicate

page_text: characters or letters, in this instance the first eight letters of the alphabet, while the
index disk E5 is provided with the same letters or characters. When said disk is
turned until one of its letters is brought opposite the pointer F, the two correspond-
ing type letters upon the wheel A5 will be brought to the two printing points. The
sleeve which carries the wheel A has fast upon it at the right of the gear Ba
ratchet G with which co-operates a holding pawl in the form of a bent lever H5
whose forward end extends downward from the pivot of the lever and projects into
the path of a cam I5 fast upon the rotary shaft R heretofore described.
A spring J5
connected to the lever H³ normally holds its rear end in engagement with the
ratchet G so that when the shaft D5 is turned in the direction of the arrow, Figure 1,
to bring some letter upon the index disk E³ opposite the pointer F5 and the
corresponding type letters to the printing point the engagement of the pawl lever
with the ratchet will hold the parts in the position to which they may be turned.
They will remain in this position, during the operation of the machine, until after
the printing has been effected, wherenpon the cam I will contact with the lower end
of the lever H5 and throw its rear end upward, out of engagement with the ratchet,
whereupon the parts will be reset to normal position by a coiled spring K5 surrounding
the shaft D and secured at its front end to said shaft and at its rear end to the fixed
bearing of the rear end of said shaft. As explained in the prior application these
devices are employed for the purpose of designating either different classes of
transactions, or sales made by different clerks, and preserving a record showing the
character of the transaction represented by each amount printed upon the record
strip and check strip, or the particular clerk by whom each sale was made.
At
Mounted at the right of the type wheels C2 upon an axis concentric with that of
the wheels, are the consecutive numbering wheels E2. The primary one of these
wheels is advanced one number at each operation of the machine by a cam F2,
Figure 9, fast upon the rotary shaft R¹, heretofore described, said cam at each
operation of the machine reciprocating the pawl G2 which said wheels are actuated
in the usual well known manner. These consecutive numbering wheels are provided
with double series of numbers diametrically opposite each other so that types
representing the same numbers are always presented at the two printing points.
Immediately at the right of the wheels E2 is located a fixed disk H2, Figure 3B,
bearing in the printing line the type character "No." representing the word
"number," to be printed immediately at the left of the consecutive number.
the right of the disk H2 are the dating wheels, consisting of the two "day" wheels I²
and J, and the "month" wheel K². These wheels are fast upon the left hand ends
of three concentric sleeves I mounted upon a shaft M2 upon whose left hand end the
consecutive numbering wheels E² are mounted. Fast upon the right hand end
of the sleeves L2 at the right of the side frame plate N2 of the printing attachment,
are index disks 02, P2 and Q2, the former being fast upon the sleeve which carries
the month wheel K², the second upon the sleeve which carries the day wheel J²
and the third upon the sleeve which carries the day wheel 12. Each of these index
disks is provided with a projecting flange having a milled edge, by which the disk
may be turned to adjust the wheels. Fast upon the extreme right hand end of the
shaft M² is a metal thumb piece R2 which said shaft may be turned for the purpose
of resetting the wheels E² to zero, the usual means intermediate the shaft and the
wheels for that purpose being employed.
From the foregoing description it will be seen that there is a single printing line
at the upper and lower sides of the several sets of wheels, each line containing at its
left hand end first the type letter and the wheel A5, then next the type numbers
upon the wheels C², representing the amount registered, and at the right thereof
type numbers representing the consecutive number of the transaction, and at the
right of the consecutive number and character representing the date, so that the
date, consecutive number and amount of the transaction, and the letter indicating
its character, may be printed in a single line at each printing point.
The impression platens and means for actuating them, and the means for inking
the types, may be next described: Each platen in the present instance consists of a

page_text: long metal bar S2 having a strip of rubber confined in its side adjacent to the type
wheels. This platen is carried, in the manner hereafter described, upon the front
end of an arm U2 forming an integral part of a thin cross bar or plate V2, Figure 6,
bent to form ears at its opposite ends by which it is hung upon a rod W2 mounted
at its outer end in the frame plate N2 of the printing attachment and at its opposite
end in the main side frame of the machine, Figures 9 and 10. At its end adjacent
the latter frame the cross bar V2 is provided with a projecting arm Ws to whose
outer end is connected a coiled spring X2 whose front end is connected to the side
frame of the machine. The same ends of the cross bar V2 is likewise provided with
vertical arms Y2, that of the upper bar extending downward and that of the lower
bar extending upward, and the upper end of the lower arm Y2 fitting against the
rear side of the lower end of the upper arms. The lower one of these platen
supporting frames is also provided with a forwardly extending arm Z2 whose front
end is curved upwardly and bears against the periphery of a rotary disk A³,
Figure 10, fast upon the rotary shaft W heretofore described, said shaft extending
to the right through the right hand side frame of the machine and on across the
printing adjustment and having its extreme right hand end journaled in the frame
plate N2 of the printing attachment. The engagement of the arm 72 with the
disk A³ normally holds the platen supporting frames in the position shown, with
the platens retracted from the type wheels, against the stress of the springs X2
tending to throw the platens against the types. The disk A³ however is provided
with two notches (or with a wide cut away space and a deep notch and when one of
them is brought opposite the end of the arm 72 the platen frames will be no longer
held in normal position against the stress of the springs, but the latter will be
permitted to throw the platens against the types.
In this manner at each operation of the machine and complete revolution of the
disk As the platens will be thrown against the types and retracted to normal position
twice in succession, for a purpose hereafter explained.
In order that the platens may strike the types a quick short blow and be instantly
retracted therefrom they are secured to the front ends of the arms U2 of the platen
supporting frames, in the following manner: Each of said arms has secured upon
its front end, opposite the cross bar S2 which carries the rubber strip, a block B³.
Near its opposite ends each of these blocks is provided with a vertical bore
cominunicating at its lower end with a smaller hole in the front end of the arm U²,
Figure 9. Coiled springs C³ are confined in these bores and screw pins are
passed through them and screwed into the platen bar S2, the springs being confined
between the heads of the screws and the bottom of the bores in the block 133.
When the platens are drawn toward the types by the action of the springs X2
the arms U2 of the platen supporting frames are arrested by contact with stops D³
projecting from the main side frame of the machine, before the platens have
struck the types, whereupon the momentum of the platen bars S2 carries them
onward against the types, overcoming the resistance of the coiled springs (3, and
as soon as they have struck the types they are instantly retracted therefrom
by said springs, before the platen frames are moved backward toward normal
position by the action of the disk A³. In this manner a very quick sharp blow
of the platens against the types is obtained, and clean clear printing thereby
produced.
The means for inking the types may be next described as follows: The supply of
ink is carried in a reservoir E³ located in fixed position immediately in rear of the
type wheels, its top immediately above and its bottom below the horizontal plane of
the axis thereof. This reservoir is filled with a sponge or other absorbent filling F³
which is saturated with ink and is exposed along the open top and bottom thereof.
Pivoted at its lower end to the frame plate N2 is a vertically extending arm H³, Figure 2.
This arm has pivoted to its outer side at its upper end two forwardly extending curved
arms 13 J³, to the forward ends of which are secured the extreme right hand ends of
two transverse inking strips or pads K³ L³, Figures 6, 9 and 10, the former in the
normal position of the parts resting upon the top of the ink reservoir and the latter

page_text: pressing against its bottom. Each of these inking strips consists of a metal strip
extending transversely across the type wheels and provided upon its side adjacent
said wheels with an inking pad of suitable material. At its extreme left hand end
the strip K is supported and guided in a slot in a plate M³, Figures 9 and 10, pivoted
upon the main side frame of the machine and yieldingly held in its normal position
against a suitable stop Q8 by a spring R³. The strip L³ at its left hand end rests
upon the curved upper edge of a plate N³ secured to the side frame of the machine.
Under this construction and arrangement of the parts, if the upper end of the
arm H³ be thrown forward the inking strips K³ L3 will, by such movement be
brought to position immediately above and immediately below the printing lines
across the type wheels at the opposite sides thereof, Figure 2ª. Now, at the proper
time in each operation of the machine they are moved to such position by the action
of a cam Q5 fast upon the extreme right hand end of the rotary shaft W before
referred to, said cam bearing against a projection upon the inner side of the upper
end of the arın H³ to force the latter forward against the stress of the coiled
spring R tending to hold it in normal position. The adjustment of the parts is
such that immediately after the cam Q5 has moved the parts to the position men-
tioned, with the inking strips across the printing lines, the first of the two notches in
the disk A³ will be brought opposite the end of the arm 72 and the platens be
thereby permitted to be thrown against the type wheels by the action of the
springs X2 in the manner heretofore described. At such operation the platens will
contact with the outer faces of the inking strips and force said strips against the
types, to ink them, the platens being instantly retracted by the springs C3 and
then lifted to normal position by the cam disk A³, in the manner before explained,
and the inking strips also following them slightly away from the types. Immediately
after the inking of the types the cam Q which has thrown the inking strips for-
ward to inking position will clear the projection upon the arm H, and the latter
will be retracted by the spring R5, carrying the inking strips back to normal
position. Shortly thereafter, in the operation of the machine, the second notch or
cut away space of the disk A³ will be brought opposite the end of the arm Z2 and the
platens be again thrown against the type wheels. At this second operation the
inking strips will be out of the way and nothing will interpose between the platens
and the type wheels excepting the paper strips hereafter described, so that the
printing upon said strips will be then effected.
The paper record strip heretofore mentioned is carried upon a reel S and led
thence upward over a guide rod 13 thence forward beneath the lower inking strip L³
and between the lower platen and the type wheels, and thence over a second guide
rod U3 and downward around a storage reel W. This storage reel has fast upon its
inner end adjacent the side frame of the machine a ratchet X³ with which co-operates
a reciprocating pawl, Y³, hereafter referred to, and by which the ratchet is advanced
the space of one tooth at each operation of the machine and the reel thereby turned
to draw forward the record strip after each printing operation. A holding pawl 73
engaging the ratchet prevents backward movement of the reel.
The paper check strip A4, from which the printed checks or tickets delivered from
the machine are formed, is carried in a roll upon a reel B* secured to the outer side
of the side frame of the machine near its upper end. From the rear side of said
roll the strip is led downward through a guide chute C', Figure 9, thence forward
hetween a pair of feed rollers 1 E, thence onward above the upper inking strip K³,
across the upper sides of the type wheels, through a second guide way F and out of
the machine beneath a vertically reciprocating knife bar G4 mounted at its outer end
in a guide way in the frame plate N2 and at its inner end on guides upon the main
side frame of the machine, Figure 10. The rollers D, E are geared together and
intermittently turned to advance the paper strip by means of a mutilated gear or
segment H fast upon the shaft W beside the disk A³ heretofore described. At each
revolution of said shaft the teeth of the gear H+ will engage a pinion I which in turn
meshes with a pinion J fast upon the spindle of the lower roller E and meshing
with a pinion K fast upon the spindle of the roller D. The rollers D' E' may

page_text: consist of ordinary feed rollers, but we prefer to employ combined feeding and
printing rollers, one roller bearing the type matter and the other acting as an
impression roller to co-operate therewith. In the present instance the roller D' is
the impression roller and the roller E' beneath it the printing or type roller. The
latter may bear any suitable type matter, that usually employed being the business
card of the proprietor of the establishment, with instructions to pay the cashier the
amount of the check, the attachment of the present machine producing, for instance,
such a check as that shown in Figure 8. For the purpose of inking the type
roller E there is employed the inking roller L upon the left hand end of whose
spindle is the pinion I above mentioned. This roller I is inked by a saturated ink
pad M contained in a second ink reservoir N, Figure 9, secured upon the front end
of a frame O whose rearwardly projecting arms are hung upon a rod P extending
from the frame plate N2 to the side frame of the machine. The pad M4 does not
normally bear against the under side of the roller I, but rests a short distance
beneath it, and at each operation of the machine is moved upward against the roller
by the action of a cam Q fast upon the shaft W and co-operating with a projecting
lug Rupon the front side of the reservoir N+ near the middle of the latter, the lug
resting upon the periphery of this cam and the cam operating to lift the reservoir
and press the pad against the roller L' at each operation.
The left hand or inner end of the knife bar C heretofore described is secured to a
vertically reciprocating plate or bar S* suitably guided upon the outer face of the side
frame of the machine, Figure 10, and normally held in its upper position by a coiled
spring T
In its forward edge this plate S4 is provided with a notch U with which
co-operates a cam V4 fast upon the rotary shaft R¹ heretofore described. At each
operation of the machine and rotation of said shaft the cam V4 will engage the
notch U and depress the plate S' and knife bar G at the proper time to cause the
printed check to be severed from the projecting front end of the strip A', such
severed check then resting upon the horizontal top of the angle plate W which forms
a sort of housing for the parts beneath and in rear of it. The vertically reciprocating
bar S carries the pawl Y³, heretofore referred to, whose lower end co-operates with a
ratchet Xs upon the storage reel W³ to turn the latter at each operation of the
machine and draw forward the record strip.
From the foregoing description it will be seen that the date, number and amount
of each transaction are printed in a single line transversely of the record and check
strips. Heretofore neither the date nor the number of the transaction has usually
been printed upon the record strip, merely the amount being printed on said strip,
while on the check strip the number and date, the amount, and the advertisement or
business card have been printed in order longitudinally of the strip. In such case
paper strips of about one third the width employed in our present machine have been
used, and the result has been that each check formed from the check strip consumed
about three times the length of the strip necessary in the present machine to form
such check. The check strip was theretofore used up much more rapidly in such
machine than in our present one and a new supply had to be placed in the machine
much more frequently than is necessary in our present machine where the checks are
formed by narrow transverse pieces cut from the end of the strip. Under the old
management also it was not possible to print the dates and numbers of the transactions
on the record strip without considerable complication of the mechanism, nor without
the necessity of advancing said strip so far at each operation of the machine as to
render the arrangement entirely undesirable, if not wholly impracticable.
The machine is provided with the usual forwardly and backwardly sliding money
drawer X adapted to be locked when moved to closed position by the rear end of
a lever Y, Figure 3, which catches in front of the upper edge of the rear wall of
the drawer and holds it in closed position. The front end of said lever Y* stands
in the path of a cam Z fast upon the left hand end of the rotary shaft R',
before referred to, by which cam the lever is rocked and disengaged from the
drawer at each operation of the machine, and the usual spring behind the drawer
permitted to throw it open.
