Improvements in Cash Registers and Indicators.
I, HUGO COOк, of Dayton, Ohio, United States of America, Mechanical
Engineer, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by,
the following statement :-
My invention relates to a printing attachment for cash registers, for printing
both detached checks and a permanent record; and its novelty will be herein set

The same letters of reference are used to indicate identical parts in all the
figures.
Inasmuch as the novelty of my invention lies entirely in the printing attachment
I shall describe ouly so much of the remainder of the machine as may be necessary
to explain the operation of this attachment. The general construction of the
machine, so far as here shown, is substantially the same as that shown and described
in Letters Patent of the United States No. 464,294, granted me December 1, 1891,
to which Patent reference may be had for more detailed illustration and description
of the various parts.
The main driving shaft of the machine is a revoluble shaft A, Figs. 1, 2 and 4,
upon whose right hand end (not shown) may be secured a suitable handle for
turning it. At its left hand end the shaft has secured upon it a crank arm B which
is connected by a link C to a crank arm D fast on an oscillatory shaft E. Loosely
mounted on the shaft E are four gear-toothed sectors F, only two of which, the
left hand ones, are located in the portion of the machine illustrated in the
drawings. Each of these sectors meshes with a gear wheel G which in turn meshes
with a gear H fast on the hub of an indicator wheel I, there being four indicator
wheels in the machine, one geared to each sector, and representing respectively
units of cents, tens of cents, units of dollars and tens of dollars.
Each of the segments F as shown in Fig. 4 carries a latch J consisting of a bent
arm pivoted at its lower end to a lug depending from one of the radial supporting
arms of the segment and projecting at its upper and outer end toward the periphery
of the segment. Its outer end is provided with a recess M and just below the

page_text: angle of the arm the inner edge of its vertical portion is cut out to form a recess b
and above it an engaging shoulder c for a purpose to be presently explained.
A spiral spring secured at one end to one arm of the segment and at its
opposite end to the arm J near its angle tends to pull the arm rearward
and throw its outer end upward. A pin pupon the side of the segment
limits the play of the arm in a downward direction. Fast upon the side of
the arm J is an arm P whose upper end or nose is wider than the body of the arm.
The laterally projecting portion of the nose of this arm normally bears against
the forward side of a cam lug r upon the inner face of a radially sliding plate s
which holds the arm J in the position shown in Fig. 4 against the tension of the
spring which tends to pull it in the opposite direction. The plate s is supported
on the framework at its outer end by a pin passing through a slot in the plate, and
at its inner end is provided with a slot which embraces the central oscillatory
shaft E while a spiral spring t constantly tends to pull it rearward and withdraw
its lug from engagement with the nose of the arm P on the arm J and permit the
spring to pull the latter rearward. The plates is normally held in the forward
position (shown in Fig. 3) by a detent plate O which co-operates with the series
of keys N of the bank to which the actuator and associated parts now being
described belong. This detent plate is segmental in form and is supported by
radial arms upon the central shaft E. It is provided on one side with a series of
detents w which are adapted to engage notches in the stems of the keys N when
the latter are pressed inward as seen in Fig. 4. The keys as shown are carried in
segmental guide plates and are surrounded by spiral springs interposed between the
inner guide plate and the pins passed through the keys which springs yieldingly
hold the keys in and return them to normal position. When any key is pushed
in, the inner end of its stem strikes the bevelled side of its co-operating detent w
and rocks the detent plate O slightly upward as it passes the detent, and the latter
then engages the notch in the key and holds it in this inward position as shown in
Fig. 4. A spiral spring a connected to the lower end of the detent plate O tends to pull
the plate downward and hold it in the position shown in Fig. 4 in which position a
tooth y upon the side of the plate engages a notch in the upper edge of the plate s
before described, and normally holds the latter plate in its forward position,
against the tension of the spring t tending to pull it rearward.
Fast upon the shaft E between the plates and the segment F is a cam
plate K in the same vertical plane as the arm P upon the arm J before described,
while upon the side of the plate K next to the segment F and in the same
plane as the arm J is a lug L. The periphery of the cam K at the side
of the lug L is cut away as shown at e for a purpose to be presently
explained. A pin or lug a¹ projects from the side of the cam K into the plane
of the lug upon the inner side of the plates and in the normal position of
the cam K stands at the rear side of the lug r as shown in Fig. 4. If when the
parts are in the position shown in Fig. 4 where the laterally projecting portion
of the nose of the arm P bears against the forward side of the lug and holds the
arm J in its outer position the handle is revolved and the shaft E thereby oscillated
forward and back, as before described the lug L will just clear the rounded face of
the shoulder c on the arm J and will pass by it in both directions without moving
the arm J, but if before the handle is revolved, any one of the keys N is pushed
inward and the detent plate O thereby thrown upward as before described, the
tooth y on the lower end of the detent plate will be withdrawn from the notch in
the plates and the latter be thereby released from said plate; but it will be held
from moving rearward under the tension of its spring t by the engagement of the
pin a' on the cam K with the rear side of the lug but as the shaft E and cam K
oscillate forward, the pin a' is carried below the lug r so that the spring t can then
pull the plate s slightly rearward, its movement in such direction being arrested
either by the engagement of the tooth y with a shoulder above and in front of the
notch in the plate or determined by the length of the slots in its ends. This
rearward movement of the plates withdraws the lug from the nose of the arm P

page_text: and permits the spring i to pull the arm J slightly rearward until the arm P
engages and rests upon the periphery of the cam K, the nose of the arm P as
before explained being wide enough to engage both the lug r and the cam K. This
engagement of the arm P with the cam K is then the only thing which prevents
the spring from pulling the arm J still farther rearward. Such being the case, as
soon as the cam K is moved forward and downward until the cut out space é in
its periphery is brought beneath the nose of the arm P and the lug L into line
with the recess b in the arm J the spring; will pull the arm J farther rearward and
engage the recess with the lug L. This will connect the shaft E with the segment F
so that when the shaft begins its backward movement it will carry the segment
with it until the outer projecting end of the arm J below the recess M strikes the
inner end of the key which has been pressed in, whereupon the arm J will be
arrested by the key and rocked far enough on its pivotal support to permit the
lug L to slip out of the recess 6 and thereby disconnect the oscillating shaft from
the segment, the former returning to its initial position alone and the latter
remaining at the point where it has been arrested by the engagement of the arm J
with the operated key. The inner end of the operated key enters the recess M
in the outer end of the arm J and the engagement of the nose of the arm P with
the periphery of the cam K holds the arm J in this position during the further
return movement of the cam K and shaft E, and the arm and segment thereby
become locked to the key and cannot move in either direction until the key is
released. Just as the shaft completes its backward stroke a set screw carried by
an arm fast upon the shaft E strikes the rear side of a lower extension of one of
the radial supporting arms of the detent plate O and rocks said plate slightly
upward, thereby releasing the operated key and permitting its spring to throw it
outward to normal position. The adjustment of the parts is such that the shaft E
completes its backward stroke shortly before the operating handle reaches its
initial position and the shaft is moved slightly forward again to the position seen in
Fig. 4 before the handle reaches such position, so that when the handle comes to
rest, the set screw has been moved out of engagement with the extension of the
detent plate and the spring has pulled the latter downward again to normal
position, so that when another key is pushed inward it will be caught and held by
its co-operating detent as before explained. During the return upward movement
of the cam K, the pin a' engages the bevelled lower portion of the rear side of the
lug and forces the plate s forward to normal position as shown in Fig. 4. and the
tooth y reengages the notch in the plate s.
The adjustment of the parts is such that when the sectors are in the position of
the one seen in Fig. 4 the indicator wheels I all stand with their zeros exposed at
the reading opening in the casing of the machine. As the sector is carried
backward with the shaft E, in the manner before explained, the indicator wheel is
turned forward from zero, and when the latch plate J engages the operated key
and the sector is arrested the number upon the indicator wheel which corresponds
to the operated key will be exposed at the reading opening.
The gear wheels G, which are driven by the sectors F and in turn drive the
indicator wheels I (as well as the registering wheels I', Fig. 4,) are fast
upon a series of concentric sleeves mounted upon the shaft Q, Fig. 4.
The gear
at the extreme right of the machine, not shown, is fast upon the right hand end of
the inner sleeve; the second gear is fast upon the end of the second sleeve; the
gear G shown in Fig. 4 is fast upon the third sleeve, and the next gear to the left,
which drives the fourth indicator wheel, is fast upon the outer sleeve.
Upon the extreme left hand end of the sleeves are secured four type-carriers R,
Figs. 1, 3 and 5, each bearing a zero and a series of nine type figures representing
units, from 1 to 9 inclusive. In addition, the right hand carrier, which is made
wider than the others, has a $ type beside each of its numbers. The extreme left
hand type carrier and the extreme right hand gear wheel G (not shown) are fast
upon opposite ends of the inner sleeve, Fig. 10, so that this type carrier and the
indicator wheel which represents units of cents will turn together. The next type

page_text: upon
carrier is fast upon the same sleeve as the second gear wheel G from the left of the
machine, so that this carrier and the indicator wheel which represents tens of cents
will turn together. The third type carrier from the left is fast upon the same
sleeve as the gear wheel G shown in Fig. 4, so that this carrier and the indicator
wheel which represents units of dollars turn together; while the type carrier
the extreme right and the gear wheel upon the extreme left are fast upon the same
sleeve, so that this carrier and the indicator wheel representing tens of dollars turn
together. The arrangements of the parts is such that when a number upon any
indicator wheel is brought to the reading opening the same number upon the
same number upon the corresponding type wheel will be brought to the printing point.
The shaft Q, Fig. 4, is a revoluble one and is geared to the shaft A near the left
hand side of the machine, at a point not shown in the drawings. Like the shaft A
it makes a complete revolution at each operation of the machine.
Secured upon the left hand side of the machine is a framework S, Figs. 1, 2, 3
and 5, within which the type carriers above-mentioned, and other associated parts
hereinafter described, are located. Fitting in an inclined guideway in the outer
wall of this framework, at T, Figs. 1 and 2, is a sliding bar U, Fig. 3, which
carries at its lower end an integral plate V projecting inward, at right angles to
the bar U, beneath the type carriers R, Figs. 1, 3, 5 and 10. This plate V carries,
among other things, an impression platen W, which co-operates with the type-
carriers R.
Fast upon the outer end of the shaft Q, Figs. 1, 2 and 3, is a disc X fitting
against the outer side of the frame S and sliding bar U. This disk has upon its
inner face a cam groove Y, shown in dotted lines in Fig. 3, and in solid lines in
Fig. 34, in which groove fits a stud Z upon the outer face of the bar U, Fig. 10.
The result of this is that when the shaft Q and disk X are revolved, in the
direction of the arrow in Fig. 3, the bar U is slid back and forth in its guideway
in the frame S and the plate V and impression platen W moved away from and
toward the type-carriers R.
The
paper strip A', from which the checks are cut, is carried on a reel B', from
which it is led rearward and upward beneath spring clips C¹ on the frame S, Fig. 5.
Thence between a feed-roller D¹ and the flanges E' of a cylinder F¹ which bear
against the feed roller, as seen in Fig. 2, thence forward through a guide chute
between an upper plate G¹ and lower plate H₁; and thence forward over the
plate V and platen W, beneath the type-carriers R. In Fig. 5 the plate V is in
nearly its uppermost position, with the platen W nearly in contact with the type-
carriers R, having been lifted to this position by the cam groove Y in the disk X,
acting upon the stud Z of the bar U. The plate V carries at its rear edge a
shearing block or knive I', Fig. 5, which co-operates with the forward edge of the
plate G¹ to sever the paper strip and form the detached check. In Fig. 5 the parts
are shown in the position which they occupy when the operating handle of the
machine is in its normal position of rest. During the early part of the operation
of the machine, as the handle moves forward from normal position, the plate V is
lowered away from the type-carriers, so that the paper strip can then be fed over it
from the chute between the plates G₁ H₁, and as the handle comes on around to
normal position again, after the type-carriers have been moved in the manner
heretofore described to bring to the printing point their numbers which correspond
to the operated keys, the cam groove in the disk X lifts the bar U and plate V
again, causing the block I' on the rear edge of the plate to shear off the check
from the paper strip, and the platen W to press it against the types to effect the
printing. After the check has been severed from the strip and printed, it is
removed from the machine by hand, as hereinafter referred to, the forward end of
the check being within easy reach of the operator at the edge of the plate V.
The feed-roller D' and flanged cylinder Fare driven by a train of gears from
the shaft Q, as shown in Figs. 2 and 3, the uppermost one of which gears is
fast upon said shaft just inside the outer wall of the frame S. The flanges E' on
the cylinder F! are cut away for a portion of its circumference, as seen at the

page_text: lower side of the cylinder in Fig. 5. The check strip will be fed along only
while the flanges E¹ bear against the feed-roller, so that when these cut-away
spaces come opposite the feed-roller, the movement of the strip ceases.
The
adjustment of the parts is such that they come opposite the fecd-roller just
before the shearing block I, in the upward movement of the plate V, reaches
the plate G¹, to shear off the check. While the check is being severed and
printed the check-strip remains at rest, and it does not begin to move again
until the next operation of the machine has advanced far enough to lower the
plate V and carry the block I¹ below the plates G¹ H'.
Hung by arms J' in a swinging frame K¹ carried by a sleeve fitting over the
type-carrier sleeves, Fig. 10, is an inking roller L', Fig. 5, arranged to travel over
the faces of the type-carriers to ink the type. To the supporting side arm of the
frame K is pivoted the upper end of a link M whose lower end is pivoted to
the outer side of a disk N' fast upon the end of the oscillatory shaft E, Fig. 4,
heretofore described. It will be remembered that at each complete revolution
of the driving shaft of the machine the shaft E' is oscillated forward and back-
ward. As the shaft E and the disk N' oscillate forward, in the direction of the
arrow in Fig. 5, the link M¹ draws the frame K¹ downward and moves the inking
roller L over the face of the types. During the backward oscillation of the
shaft E and disk N¹ the type-carriers are set at the proper numbers, the frame K¹
and inking roller lifted to normal position again, and the impression platen brought
up to effect the printing, as before described. A spring O', Fig 1, coiled around
the shaft P by which the arms J¹ are hung to the frame K and bearing at
one end against one of the arms J', yieldingly presses the inking roller against
the faces of the type-carriers.
Hung upon the shaft P is a thin arm or plate Q' which fits between two of
the type-carriers and has its lower end extended downward and rearward over the
platen W. One end of the spring O', above described, bears against the upper
end of this arm, as seen in Fig. 1, and tends to press it rearward and throw its
lower end downward. When the plate V and platen W are lowered at the
beginning of the operation of the machine the spring O' throws the upper end
of the arm Q' slightly rearward, until it is arrested by the cross-bar of the
frame K¹. This causes the lower end of the arm Q to project below the type-
carriers R, so that as the plate V is lifted, during the second half of the operation
of the machine, the end of the paper strip which projects over the plate is caught
between the arm Q1 and the platen W before or at the time the check is severed
from the strip by the block I and plate G', and the detached check is then held from
displacement by the arm Q' until the printed is effected, said arm being pressed
upward, against the resistance of the spring O¹, as the platen is lifted to the
position shown in Fig. 5.
In addition to the printing of the detached checks I provide for the printing of
each amount upon a permanent record-strip R'. This strip, which, for convenience,
may be narrower than the check strip, is carried upon a supply reel or spool S¹
loose upon a shaft T carried by a support depending from the plate V. From the
spool S¹ the strip is led up through an opening in the plate V, Fig. 5, thence for-
ward over the platen W, thence down through a second opening in the plate, and
thence forward around a storage spool U₁ loosely mounted upon a shaft V¹
carried by a support W₁ projecting forward and downward from the plate V.
One flange or disk X' of the spool U has a toothed or milled edge, with which
co-operates a pawl-tooth Y carried by an arm hung on the shaft V¹,
Figs. 3, 5, 11 and 12. The pawl tooth itself is on a short arm Z2 pivoted to the
outer end of the arm Z'. A lug on the arm Z fits against the inner face of a
flange on the disk X, indicated by the dotted lines in Figs. 5 and 12, the flange
being embraced by the tooth Y and lug Z and permitting a very limited play of
the arm upon its pivotal support. A spring Z confined in a recess in a lug Z
on the side of the arm Z' bears at its lower end against the upper side of the
arm Z and yieldingly holds the tooth Y' in engagement with the edge of the

page_text: disk X. Whenever the arm Z' is swung upward the tooth Y₁ will carry the
disk with it, turning the spool U₁ and drawing the check-strip R¹ from the
spool S¹, over the platen W and winding it on the spool U. During the down-
ward movement of the arm Z' the spring 7 permits the tooth Y¹ to slip over the
edge of the disk X' and a pawl Z³ carried by the frame V and spring-pressed
against the edge of the disk at its opposite side prevents any backward movement
of it.
The arm Zis swung up and down, to turn the disk X, in the following manner
and by the following means: A plate A2 pivoted at its lower end to the side of
the machine at B2 bears at its upper end against the record-strip wound on the
spool U¹, a spring A3 at its lower end yieldingly holding it there. This plate has
in it a slot C, Fig. 1, which embraces the disk X' and forms an arm D' on the
right hand edge of the plate. This arm is cut off, or made shorter than the main
body of the plate, and in the drawings is shown bent slightly forward, out of the
plane of the body of the plate. The arm Z which carries the pawl-tooth Y¹ rests
upon the upper end of this arm D2 of the plate A2, Fig. 12. It results from this
that when the plate V is lowered, at the beginning of the operation of the machine,
the pivotal support V₁ of the inner end of the arin Z will be lowered, while the
outer end of the arm will be held up by the arm D2 of the plate A³, so that the
pawl-tooth Y will turn the disk X¹ and spool U₁. When the plate V is lifted
again, near the end of the operation of the machine, the inner end of the arm Z¹ is
raised again and the arm resumes the position shown in the drawings, a spring V⚫,
Fig. 11, coiled around the shaft V₁ and secured at one end to the shaft and at its
other to the arm Z' constantly pressing the latter against the upper end of the
arm D³. It will thus be seen that at each operation of the machine the lowering
and raising of the plate V causes the spool U to be turned and the record-strip R¹
to be drawn from the spool S', over the platen W, and wound upon the spool U¹.
The main purpose of the plate A' and arm D' is to regulate the feed of the
record-strip, since, for the operation so far described, a fixed stop supporting the
outer end of the arm Z' would be sufficient. As the record-strip is drawn from
the spool S¹ and wound on the spool U₁, and the size of the roll upon the latter spool
gradually increases, it is evident that if the spool continues to be turned the same
portion of a revolution at each operation of the machine a gradually increasing
portion of the strip will be drawn from the spool S' and wound upon the spool U¹
at each operation, and the record numbers will be printed farther and farther apart
upon the strip. I overcome this difficulty and maintain a regular and even feed of
the strip by means of the co-operation of the plate A and its arm D' with the roll
upon the spool U₁ and with the pawl-carrying arm Z. It will be seen that the
lower down and the nearer the shaft V₁ the point of engagement of the arms D'
and Z is, the greater will be the movement of the outer end of the arm Z' rela-
tively to the edge of the disk X' at each operation of the machine, and the higher
up and farther away from the shaft V₁ such point of engagement is the less will be
such movement of the arm Z. It will also be seen that as the quantity of the
paper strip wound upon the spool U₁ increases the plate A' will be gradually
moved forward and the point of engagement of the arms D' and 7 gradually
moved upward and farther away from the shaft V₁ upon which the arm Z¹ is
pivoted. The result is that the gradually-increasing size of the roll upon the
spool U causes a gradually decreasing movement of the spool, and thus sub-
stantially the same length of strip will be wound upon the spool at each operation
of the machine, whether the spool be nearly empty or nearly filled.
The printing of the amount upon the record-strip by the types on the carrier R
is not effected simultaneously with the printing of it upon the check-strip, but at
the beginning of the next operation of the machine, after the detached check has
been moved by hand. As seen in Figs. 3 and 3ª, when the parts are in their
normal position of rest the stud Z on the bar U rests in a slight depression of the
groove Y at Y. The bar U has been lifted to its highest position, and the print-
ing effected by the passage of the point or cam Y³ under the stud Z, and as the

page_text: depression at Y' came under the stud the bar U has been slightly lowered again,
thereby releasing the check which had been printed and permitting it to be drawn
out. This has left the record-strip R' immediately below the types, and as the
disk X is turned forward at the beginning of the next operation of the machine
the depression Y' in the groove is carried from under the stud Z and the higher
point or cam Y engages it and lifts the bar U and plate V again and the platen W
presses the record-strip R' against the types, to effect the printing.
It will thus be seen that at each operation of the machine the amount indicated,
registered, and printed upon the check-strip at the preceding operation is first
printed on the record-strip; then as the platen is lowered away from the types the
record-strip is fed along and a blank space upon it brought to the printing point,
the end of the check-strip being at the same time fed along to the printing point,
over the record-strip; then the amount corresponding to the operated keys is
indicated and registered and the type-carriers moved to the proper positions to print
that amount; then the platen carries the check-strip up against the types to effect
the printing of the amount upon it; and then, as the parts come to rest in normal
position, the platen is slightly lowered from the types, to release the printed check,
and it is drawn out by hand.
In addition to printing upon the check-strip and record-strip the amount of each
sale indicated and registered, I provide means for printing upon each check its
consecutive number, date, and such other matter as may be desired. In the center
of a cylindrical recess in the cylinder F, Fig. 5, is mounted a shaft F2, extending
the length of the cylinder and supported at its ends in the heads thereof. Upon
this shaft are mounted a series of consecutive numbering wheels G³, Fig. 6, and a
series of dating wheels H', the former actuated automatically, to cause the primary
wheel of the series to be turned one number at each operation of the machine, and
the latter adapted to be set by hand in the usual manner. Owing to the relatively
small diameter of these numbering and dating wheels only one longitudinal row of
their types project at one time far enough outward to have their faces flush with
the edges of the flanges E', so that only one row can make an impression when the
cylinder F¹ is given a revolution and the types brought against the surface of the
roller D', the latter roller acting as an impression roller in its co-operation with
the types carried by the cylinder F, and as a feed-roller in its co-operation with the
flanges E' of the cylinder F', as heretofore described. Adjacent to the cylindrical
recess which contains the type-wheels G H I place upon the surface of the
cylinder F such type matter as may be desired; in this instance "A. B. & Co.,
2359 Broadway, New York. Pay Cashier "; while immediately to the left of the
consecutive-numbering wheels, in the printing line, I place either "No." or the
sign "" to designate "Number."
When the machine is at rest, with its various parts in normal position, the type-
wheels in the cylinder F¹ are at the upper side of the cylinder, and the fixed
type-matter is upon the forward side of the cylinder. The number, date and other
matter have been printed upon the front end of the check-strip A', which now rests
upon the plate G¹, ready to be fed forward at the next operation of the machine.
At such next operation the strip is fed forward, with this printed matter upon it,
the type-carriers R and platen W print the amount of the sale upon it behind the
other printed matter, and the check is cut off by the shearing block, while at the
same time the cylinder F has made another complete revolution and printed its
matter upon the check which is to be issued at the next succeeding operation of
the machine. Thus at the end of each operation of the machine there is a partially
printed check on hand, ready to be fed forward and severed from the strip and
have the amount of the next sale printed upon it. One of the printed checks, as
it is delivered from the machine, is shown in Fig. 9.
An inking roller 12 for the type upon the cylinder F is journalled at its ends
in the frame S and geared to the cylinder, as seen in Figs. 2 and 3.
The set of consecutive-numbering wheels G' may be of the usual or any suitable
construction, and the primary wheel of the set may be actuated at each operation

page_text: of the machine in any convenient manner. In the present instance a pin G' carried
by the pawl arm G', as seen in Fig. 7, co-operates with a cam lug G³ upon the
framework, Fig. 2. The pin G³ of the pawl arm rides over the cam G' at each
revolution of the machine, thereby rocking the pawl arm and causing the pawl G'
to advance the primary wheel one number. A spring G7 resets the pawl arm after
the pin G has passed the cam G' on the frame. A pawl G prevents backward
movement of the wheels.
It may not be desirable at all times to feed out and print a check at each opera-
tion of the machine, and for that reason I provide means for throwing the feeding
devices for the check-strip into and out of operation at will. The feed-roller D¹
is loosely mounted upon a shaft J' which is eccentrically journalled in the frame S,
as indicated by the dotted line of one of its bearings in Fig. 4 and as seen in
Fig. 8. The shaft J projects outside the frame S, as seen in Figs. 1, 2 and 8, and
has splined upon its outer end a thumb-piece K2 for turning it. It will be seen
that by turning the thumb-piece K2 and shaft J to the left, Figs. 3 and %, the
feed-roller D will be carried away from the flanged cylinder F so that the revo-
lution of the roller and cylinder will not feed or print the strip A¹ passed between
them. By turning the thumb-piece K and shaft J to the right again the roller D'
will be carried back into co-operative relation with the cylinder. As seen in
Fig. 1 the base of the thumb-piece K has in it two notches K and K which
co-operate with a lug K on the side of the framework. Within the thumb-piece
is a recess, as seen in Fig. 8, in which recess a spiral spring K is confined by a
nut K screwed upon the outer end of the shaft J. This spring presses the thumb-
piece inward and yieldingly holds one of the notches K K in engagement with
the lug K on the frame. By slipping the thumb-piece outward and turning it
until the opposite notch engages the lug K' the feeding devices may be thrown into
or out of operation at will.
This device is particularly useful where it is desired to print an additional
amount upon a check already delivered from the machine. Thus in using the
machine in a restaurant, if, after a check has been delivered to a customer, he
gives an additional order, the attendant will take his check to the machine, depress
the proper keys to indicate and register the amount which is to be added to the
check, turn the thumb-piece K backward, to throw the feeding rollers out of
operation, place the lower end of the check upon the plate V beneath the type-
carriers, and then give the operating handle a revolution. This will cause the
additional amount to be indicated aud registered, and printed upon the check, and
at the beginning of the next operation of the machine it will be printed upon the
record-strip. In this manner several additional amounts may be printed upon a
check already delivered, if necessary, and each amount will also be duly printed
upon the record-strip.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
