Improvements in Cash Registering Machines.
I, REGINALD HADDAN, of the firm of Herbert Haddan & Co., of 18 Buckingham
Street, Strand, London, W.C., Patent Agent, do hereby declare the nature of this
invention, a communication to me from abroad by THE NATIONAL CASH REGISTER
COMPANY, of Dayton, State of 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:-
The present invention relates to certain improvements upon and modifications
of the cash registering machines shown and described in letters patent No. 5238,
of March 24, 1891, and No. 18,079, of October 10, 1892, to which reference may be
made for details of description unnecessary to set forth here. The novelty of the
present invention will be hereinafter more fully explained, and particularly
pointed out in the claims.

line 8-8 of Figure 7; Figure 9 an elevation of the printing attachment upon the
vertical section thereof
left hand side of the machine, and Figure 10 a

The same letters of reference are used to designate identical parts in all the
drawings.
The hub of the operating handle A of the machine is loosely mounted upon a
stub shaft projecting from the framework, Figure 1, and has fast upon it a gear
which meshes with a second gear C upon a second stub shaft supported in the
framework. The gear C meshes with a gear 1) fast upon the rotary shaft E, and
the gear D meshes with a gear F fast upon a second rotary shaft G. The shafts E
and G extend entirely across the machine to the left side thereof.
Journaled in the lower middle part of the machine and extending entirely
across the same is a rock-shaft H. Loosely mounted upon this shaft at about
equal distances apart are four gear-toothed segments I, Figures 3 and 4. Mesh-
ing with each segment is a gear wheel J, by means of which wheels and suitable
ז

page_text: intermediate gears the four indicator wheels K, K', K², and K³, Figures 1 and 2,
are geared to the respective segments. These four indicator wheels are adapted to
expose their indicating numbers to view at the front of the machine, and in order
that a similar indication may be exposed at the rear of the machine there are
provided four other indicator wheels K, K, K, and K' having their numbers
arranged in reverse position to those upon the first mentioned wheels, so as to
be read from the rear of the machine. Each of the eight wheels has a gear
fast to its side or hub. Journaled in the framework above the wheels are two
shafts L L extending entirely across the machine. Fast upon the shaft L are two
pinions M M', meshing respectively with the gears of the wheels K and K7, by
which means those two wheels are geared together and caused to move in unison.
Loosely mounted upon the shaft L is a sleeve N having fast upon its opposite ends
pinions N1, N2, meshing respectively with the gears of the wheels K¹ and K,
by which means those two wheels are geared together. The shaft L¹ has fast
upon it two pinions 00¹ meshing respectively with the gears of the wheels K
and K, by which means those two wheels are geared together, while loosely
mounted upon the shaft L' is a sleeve P having fast upon it two pinions P¹ P
meshing with the gears of the wheels K5 and K2, respectively, by which means
those two wheels are geared together. In this manner the movement of any one
of the indicating wheels facing forward is caused to move the corresponding wheel
facing rearward, to effect the same indication at both front and rear of the
machine.
Interposed in the shaft G near its left hand end, Figure 3, is a crank Q which is
connected by a pitman R with an arm S fast upon the rock-shaft H, by which
means at each revolution of the operating handle and shaft G the shaft H is
thrown forward and backward a definite distance. As before stated, the seg-
ments I, which are geared to the indicators in the manner before explained, and
which also actuate the register in the manner hereafter described, are loose upon
the shaft H, and the latter is caused to impart different degrees of its movement
to the indicators and register by connecting the segments I with and disconnect-
ing them from it, and the next feature of our invention consists in improved
means for this purpose. As in the prior machines of this character, a latch or
coupling device is interposed between each segment and the shaft for this purpose,
and each latch co-operates with one of the four sets or series of keys T mounted
radially to the shaft H in suitable guide-plates U V and yieldingly held in and
returned to their outer positions by coiled springs surrounding them between the
two guide-plates and confined between the plate V and pins W passed through
the stems of the keys. Formed upon one side of the lower radial supporting arm
of each segment I is a guide-way X, Figures 3, 3, and 4, in which fits a sliding
latch plate Y, pulled rearward by a spring Z connecting it with the segment,
(dotted lines in Figure 3) and bearing at its rear end against the curved forward
edge of a plate A' fast upon the shaft H, there being one of these plates A¹ beside
each segment I. The plate A' is cut away at its upper rear corner to form a
shoulder B. When the shaft H is thrown forward by turning the operating
handle, the curved forward edge of the plate A moves past the rear end of the
latch plate Y until the shoulder B clears said plate, whereupon the spring Z pulls
the plate Y rearward and causes its rear end to catch over said shoulder. The
result of this operation is that just at the end of the forward movement of the
rock-shaft H the latter will become coupled to the segment I by means of the
plates A and Y, and during its return backward movement will carry the segment
with it until the plate Y is disengaged in some manner from the shoulder B¹ of
the plate A The means for effecting this disengagement is the following:
Pivoted at C to a pendent extension of the segment I, Figure 3, is a bell-crank
plate D whose upper end passes through a slot in the lower wall of the guide-
way X and is loosely pivoted to the sliding latch plate Y. The lower horizontal
portion of the plate D extends forward beneath the front end of the guide-way X,
while in rear of its pivot the plate is provided with a projecting lug between which

page_text: and the underside of the guide-way X is interposed a spring E. This spring
acts, as does the spring Z heretofore referred to, to press the latch plate Y rear-
ward, and one or the other of the springs may be dispensed with without affecting
the mode of operation of the parts. Pivoted to the lower corner of the front end
of the plate D¹ is a trip F¹ whose upper end is pressed outwardly by a spring Gi
interposed between it and the end of the plate D₁. The lower rear end of the trip
bears against the under side of the plate D¹ and limits the outward movement of
its upper end under the influence of the spring E, while said upper end of the
trip is free to yield inwardly to pressure which will overcome the resistance of
the spring G. Whenever any one of the keys T is pressed inward to its limit
of movement its inner end will be projected into the path of travel of the upper
end of the trip F¹, Figure 4, so that when, during the backward movement of
the segment with the rock-shaft, the trip strikes the end of such key it will
be arrested thereby and its pressure against the key will rock the bell-crank
plate I upon its pivot C¹ and thereby throw the latch plate Y forward and dis-
engage its rear end from the shoulder B₁ of the plate A¹, thus uncoupling the
rock shaft and segment and permitting the latter to come to rest at the point
determined by the particular key which has been pressed in, while the shaft and
plate A move on backward to normal position. The inner guide-plate V of each
set of keys has secured to or formed upon it a flange provided with notches H¹
along its curved inner edge, and the front end of the latch plate Y is shaped to
fit these notches when thrown forward to uncouple the segment from the rock-
shaft in the manner above described, and as the plate Y is locked in its forward
position by the curved forward edge of the plate A¹ as soon as its disengagement
from the shoulder 13 is effected it follows that the co-operation of the front end
of the latch plate Y with the notches H serves to positively lock the segment
in the exact position at which it was uncoupled from the rock-shaft, as seen in
Figure 4, and to hold it in such position until at the next forward movement of
the rock-shaft the shoulder B of the plate A' is carried beneath the rear end of
the plate Y and the latter is again moved. rearward by the springs, whereupon its
front end will be disengaged from the notch H in which it has been resting, so
that the segment is free to move forward to initial position with the rock-shaft.
Formed integral with the lower rear end of each plate. A', or otherwise made fast
upon the shaft H, is an arm I bent laterally so that its rear end stands in the
same vertical plane as the rear arm of the segment I. The distance between the
upper side of the rear end of this arm I¹ will contact with the rear edge of the seg-
ment arm just as the shoulder 13¹ of the plate A¹ clears the rear end of the latch
plate Y, so that as soon as said latch plate has been moved rearward by the springs
the segment will be positively moved forward by the rock-shaft. By this means
during the first half of each operation of the machine all of the segments which
have been operated at the preceding operation will be carried forward to initial
position and the indicator wheels caused to present their ciphers at the indicating
points.
For the purpose of holding any key in its inner position after it has been pressed
in the keys are provided with notches which co-operate with lugs upon a detent
plate J supported by radial arms upon the rock-shaft H, there being one of these
plates for each row of keys. Mounted beside each of the plates A¹ is a sliding
latch plate R¹ supported at its rear end upon the shaft H and at its front end upon
a screw Sentering the framework and pulled rearward by a spring T. Each of
these latch plates R' co-operates with the lower end of one of the detent plates J',
the latter normally engaging a shoulder upon the upper edge of the front end of
the plate R¹, as seen in Figure 3, to hold the latter from rearward movement
under the influence of its spring T₁ until the detent plate is lifted by pressing in
some one of the keys T. Each plate R¹ has secured upon its side adjacent to the
plate A¹ and segment an inwardly extending plate U adapted to co-operate with
a stud V¹ upon the side of the latch plate Y. When the parts are in the position
shown in Figure 3 the engagement of the plate U₁ with the stud VI will hold the

page_text: plate Y from rearward movement even when the plate A¹ has moved forward until
the shoulder B¹ has cleared the rear end of the plate, so that while the plate Y
is held in this position no coupling of the rock-shaft to the segment can be effected.
When any key in the series is pressed in, however, and the detent plate J¹ thereby
lifted and its lower end disengaged from the shoulder of the sliding plate R¹ the
latter will be pulled rearward by its spring T and the plate U¹ be carried away
from the stud VI, as in Figure 4, so that the latch plate Y is then free to move
rearward as soon as the shoulder B₁ of the plate A¹ has been carried below its rear
end. The result of this provision is that when no key in any row has been
pressed in the segment corresponding to such row of keys will not be coupled to
the rock-shaft at the end of the forward movement of the latter, and will remain at
rest, while if a key in the row has been pressed in such coupling will be effected. At
the resetting of the segments, during the first half of the operation of the machine,
the studs V upon the latch plate Y will contact with the upper forward corners
of the plates Ui just before the segments have reached their forward limit of move-
ment, and the latches will be forced forward as the studs ride over said plates and
the rear ends of the latches be thereby disengaged from the shoulders B¹ of the
plates A. This is the operation assuming that no key in any row has been
pressed in, but if a key in any given row has been pressed in, as of course will
be the case in the ordinary operation of the machine, then the sliding plate R¹
corresponding to such row will have been pulled rearward by its spring T and its
plate have been carried so far rearward that it will not serve to disengage
the latch Y from the shoulder R' at the end of the forward movement of the parts,
and the segment will therefore remain coupled to the rock-shaft and be carried
backward by it. If, therefore, at two or more succeeding operations of the
machine keys in the same row are operated the segment and rock-shaft will not be
uncoupled at the end of the resetting movement of the segment, the segment at
each operation being simply picked up by the rock-shaft and carried forward to
initial position by it, and then carried backward by it until disengaged by the
operated key.
For the purpose of positively retaining in initial position such elements as are
not coupled to the rock-shaft, and to prevent their being accidentally moved back-
ward by frictional connection or otherwise, the plate U is provided with a
shoulder or hook and the upper half of the stud V upon the latch plate is cut
away to form a flat locking surface to co-operate with such shoulder or hook. The
result is that at the resetting of a segment corresponding to a row of keys in which
no key has been pressed in the segment will not only be uncoupled from the rock-
shaft but will be positively locked in initial position, as in Figure 3.
The purpose of pivoting the trip F¹ upon the plate 11, instead of rigidly secur-
ing it thereto or providing the plate with a simple projection to contact with the
operated key, is to permit the resetting movement of the segment after a key
below the latch plate has been pressed in, the trip yielding when it strikes such
key and slipping over it. But for this the trip might be dispensed with and the
front end of the plate D¹ be made to contact directly with the keys. There may
be substituted for the trip a spring arm secured to the plate D¹ and arranged to
contact positively with pins upon the keys in one direction and to yield and slip
over them in the other, as may be readily understood without illustration here.
Near the end of each operation of the machine all the plates R' are thrown
forward to normal position, permitting the detent plates J¹ to drop behind the
shoulders upon the plates R¹ and release the operated keys, by cams or other pro-
jections Y¹ fast upon the rock-shaft, which projections contact with studs Z' upon
the plates R¹ and force them forward.
The general results above described, of coupling the rock-shaft to the segments
and uncoupling them therefrom at different points by the operated keys, and of
returning the segments to initial position at each operation and uncoupling such
of them as correspond to rows of keys in which no keys have been operated, have
been accomplished in the prior machines heretofore referred to, and our invention

page_text: in this respect relates to the novel and improved means for accomplishing such
old results.
For the purpose of positively disconnecting each segment from the rock-shaft
at the limit of backward movement of the segment, in case by any chance a
segment should remain coupled to the rock-shaft and no key be in position to dis-
engage it therefrom, each of the inner guide plates V has secured upon its side
adjacent the uppermost key in the row a plate W whose lower end stands in the
path of travel of the front end of a plate X secured upon the side of the bell-crank D¹
heretofore described. In case the segment is not uncoupled from the rock-shaft
by the engagement of the inner end of some key with the trip F¹ upon the front
end of the plate D¹ in the manner heretofore described, then the contact of the
plate X with the lower end of the plate W₁ at the limit of the backward move-
ment of the segment will effect such uncoupling.
From the foregoing description it will be understood that when a key in any
set is pressed in and the operating, handle then given a complete revolution the
segment I corresponding to such set of keys will be coupled to the rock-shaft H
and be carried backward with said shaft a distance proportionate to the position
and value of the operated key, and that such backward movement of the segment
will turn the corresponding indicator wheels to expose to view at the front and
rear of the machine indicating numbers representing the value of such key.
Such backward movement of the segment will also be transmitted to the register-
ing mechanism, to add the value of the operated key thereon, and that mechanism
and the means for transmitting the movements of the segments to it, embodying
another feature of our invention, may be next described, reference being had more
particularly to Figures 3, 4, 5, and 6.
The registering wheels are mounted upon a rotary shaft B2 extending entirely
across the machine in front of the shaft E, and journaled at its opposite ends in the
framework of the machine. There are in this instance seven registering wheels
mounted upon the shaft B2, of which the right hand one C¹ is adapted to register
units of cents and co-operate with the right hand set of keys and associated
mechanism, the second one C³ registers tens of cents and co-operates with the
second set of keys, the third one C registers units of dollars and co-operates with
the third set of keys, the fourth one C registers tens of dollars and co-operates
with the ten dollar key of the fourth set, while the fifth, sixth, and seventh wheels
register respectively hundreds, thousands, and tens of thousands of dollars and are
actuated from the wheel C by suitable transfer devices. The four wheels C¹¹ to C+
are driven by the respective segments I, with which they are thrown into and out
of gear for that purpose. In the prior machines of this character shown and
described in the two patents heretofore referred to there was a pinion for each
registering wheel mounted upon the shaft B2, which pinion was in constant mesh
with one of the gears J, so as to be turned backward and forward at the move-
ments of the segment I, and a ratchet and pawl connection was interposed between
the pinion and registering wheel to cause the latter to be turned in one direction
by the pinion and segment but not in the other. In the present machine we
have provided means for positively throwing the registering wheels into and out
of gear with the segments, so that they are in gear with them during the back-
ward indicating and registering movements of the segments, and out of gear with
them during their forward resetting movements, and the ratchet and pawl con-
nections above referred to are thereby dispensed with. This new mode of oper-
ation, and the means for accomplishing it, constitute one of the features of our
Loosely
invention relating to the registering mechanism of the machine.
mounted upon the shaft B³ (or upon the extended hubs of the registering wheels)
for each of the four registering wheels, C₁ to C,
are four pinions D³, one
Figures 5 and 6. These four pinions are permanently geared, directly or in-
directly, to the respective gears which mesh with the respective segments I, as
heretofore described, Figures 3 and 4. The pinions which are located in line
with their co-operating gears J mesh directly with such gears, while those which

page_text: Each
are not in line mesh with segments E2 fast upon the hubs or sleeves of the gears J,
as in the case of the one shown in Figures 3 and 4. The pinions D² are thus
turned forward and backward by the movements of the segments I.
pinion D has fast upon its side a smaller pinion F, and fitting against the same
is a pinion G2 fast upon the hub or sleeve of the registering wheel which is to be
actuated by such pinion D³. The pinions F2 and G being loose upon the shaft Ba
and free to turn independently of each other, it follows that the movements of the
pinions DF will have no effect upon the pinions G2 and registering wheels un-
less the pinions 12 F2 be in some manner connected to the pinions G². For the
purpose of effecting this connection there are provided four smaller pinions H
mounted upon arms I2 fast upon and projecting upwardly from a rock-shaft Ja
extending across the machine below and in front of the train of wheels upon the
shaft B2 One of the pinions H2 is located adjacent each of the pinions 12,
immediately in front of the pinions F2 G2 beside each pinion D2, and the pinion H
is sufficiently wide to mesh with both the pinion F2, Figure 5, and the pinion G²
when thrown rearward into engagement therewith by rocking the shaft J. (It
should perhaps be mentioned that in Figure 3 the pinion H2 is not in mesh with
the pinion D, though the position of the parts make it appear so in the drawing.
The pinion H2 is beyond the pinion D2 in said view, at the left of the latter pinion,
and when thrown rearward into mesh with the pinions FG2 passes behind the
pinion D, Figure 4.)
From the foregoing description it will be understood that so long as the
pinions H2 remain in their forward position shown in Figure 3 the pinions D³
will remain disengaged from their respective registering wheels and be idly
turned by the gears J and segments, but when the shaft J is rocked and the
pinions Hare thrown rearward into mesh with the respective pairs of
pinions F2 G2, as in Figure 4, the pinions D2 will be thereby connected with the
pinions G2 and registering wheels, so that the registering wheels will be
positively geared to the segments I and the movements of the latter
transmitted to them. The rock-shaft J has secured to it a depend-
ing arm L², Figures 3 and 4, to which is pivoted the front end of an
arm M² whose rear end is slotted and embraces the rotary shaft G heretofore
described. A cam 02 fast upon the shaft G co-operates with a pin 12 upon the
side of the arin M2 to throw said arm forward and backward at each operation of
the machine and revolution of the shaft G, and the adjustment of the parts is such
that the arm M will be thrown forward at the beginning of a backward movement
of the rock-shaft H, to carry the pinions H into mesh with the pinions F2 G2, so
that the backward movements of any of the segments I will be transmitted to the
corresponding registering whoels. Before the rock-shaft II has completed its
backward movements, but after the segments I have been given their complete
backward movements, the cam 02 will draw the arm M² rearward again and dis-
engage the pinions H2 from the pinions F2 G2, and they will remain so disengaged
during the forward movement of the rock-shaft and forward resetting movements
of the segments I at the next operation of the machine.
In this manner and by this means the registering wheels are thrown into gear
with the segments at the beginning of the registering movements of the latter,
and out of gear with them at the end of their registering movements, so that
during the time the wheels are to be actuated by the segments they are positively
geared to them, while during the time they are not to be actuated by the segments
they are wholly disconnected from them.
It will of course be understood that by making the pinions G2 of the same size
as the pinions D2 and locating the pinions H2 a little further forward in their
normal position the pinions F might be dispensed with and the pinions G2 be
placed directly against their respective co-operating pinions D2, the employment
of the pinions F2 in the machine shown in the drawings being simply a matter of
convenience in construction. Again, if the construction of the machine were such
as to conveniently permit such arrangement the pinions D2 F2 might both be

page_text: dispensed with and the pinions G2 be arranged in such relation to the gears Jor
segments I as to permit the idle pinions H2 to mesh directly with the gears J or
segments I and the pinions G2, with the same result.
For the purpose of locking the pinions Ha from turning while in their forward
positions, and holding them in proper position to mesh with the pinions F2 13
when thrown rearward, there are provided a series of fixed locking arms or dogs Q
fast upon a fixed shaft R2 and adapted to engage the pinions H² when the latter
are thrown forward, and lock the same, Figure 3.
The transfers between the registering wheels C₁, C² C³, and C are effected by
substantially the same devices as those shown and described in the last of the two
patents, heretofore referred to, and need not be shown and described in this case;
nor need the transfers between the wheel C and the three supplementary regis-
tering wheels at its left, which may be of any suitable form.
The
the
As seen in Figures 1 and 2 the fourth or left hand set of keys contains only one
cash key which is the uppermost one in the set and represents ten dollars.
remaining keys bear letters of the alphabet, which are used to represent either the
different salesmen who operate the machine, or different classes of sales, as is
common in the use of machines of this character. The indicator wheels K and K
are numbered and lettered to correspond to the keys in this set, and all of the keys
co-operate with said wheels, so that when any key in the set is pressed in and the
operating handle given a revolution the indicator wheels K and K will expose at
the indicating point the letter or number corresponding to that upon the key.
These indicator wheels are therefore geared to the fourth or left hand segment in
the same manner that the other wheels are geared to the other segments, but in-
asmuch as only one key in the set co-operates with the registering mechanism
provision must be made for transmitting motion from the segment to the regis-
tering mechanism only when the uppermost key in the set, representing ten
dollars, is operated. To that end the segment E which meshes with the pinion De
which drives the fourth registering wheel C. Figure 4*, has all of its teeth cut
away excepting a few at its extreme rear end. This segment is fast upon the
hub or sleeve of the fourth or left hand gear J which meshes with the fourth
segment I at the extreme left side of the machine. When said segment moves
backward the gear J and segment 2 will be turned forward by it without moving
the pinion 12 until the segment I has nearly completed its backward movement,
whereupon the teeth at the upper rear end of the segment will engage
pinion D and turn it one tenth of a revolution before the segment I is discon-
nected from the rock-shaft H by the ten dollar key and comes to rest, thus turning
the registering wheel C* one tenth of a revolution and adding ten dollars upon it.
At the next operation of the machine and forward movement of the segment I
the segment E, as it moves out of engagement with the pinion 13, will turn the
latter backward one tenth of a revolution to normal position. In this manner
and by this means the segment I is caused to transmit all of its movements to the
indicator wheels, but to co-operate with the ten dollar registering wheel only
when the ten dollar key is operated. In the present instance the pinion 12 has a
circular disk 10 secured to or formed integral with it upon one side, whose
periphery is flush with the ends of the teeth of the pinion and has its rear side
cut away to fit against the edge of a curved plate E secured upon the side of the
segment E The disk Di is thus locked against the plate E' and the
pinion D2 held from turning until, in the forward and downward movement of
the segment and plate the rear end of the latter, which terminates in front of the
teeth upon the rear end of the segment, passes below the notch or cut-away space
in the disk 110, at which moment the teeth upon the segment engage the
pinion D2 and turn the same. In the backward movement of the parts the
disk 110 is returned to the position shown in the drawing by the time the teeth
upon the segment clear the teeth upon the pinion, so that the latter is
always locked from movement except when engaged by the teeth upon the
segment.

page_text: The remaining feature of our invention relates to the printing attachment and
the means for automatically ejecting the printed checks. The gears J, which
mesh with the segments and drive the indicators and registers, are secured upon
the right-hand ends of concentric sleeves A³ free to turn independently upon the
shaft E. The shaft and sleeves extend through and project beyond the left hand
side of the machine and have fast upon their respective outer ends the type-
carriers V, Figures 2 and 9, as shown and described in detail in the aforesaid
Patent No. 18,079. These type-carriers are arranged within a supplemental
frame B3, which has upon its outer or left hand side an inclined guide-way C³,
Figures 7 and 9, in which is fitted to slide a bar or plate D³ carrying at its lower
end a plate E3 projecting to the right beneath the type-carriers, at right angles
to the plate D³, Figures 7 and 10. The plate E³ carries the platen F by which
the paper strips led over the platen are pressed against the type-carriers to effect
the printing. The shaft E extends through a slot in the plate 13 and has fast
upon its outer end a disk G³, Figures 2 and 7, and dotted lines Figure 9, which
disk has formed in its inner side, adjacent to the plate D³, a cam groove in which
fits a stud H3 projecting from the sliding plate 13 mounted in the inclined guide-
way, the revolution of the shaft E thus reciprocating the plate 13 and carrying
the platen upward against and downward away from the type-carriers, as fully
shown and described in said last mentioned patent. There are two paper strips led
between the type-carriers and platen, the upper strip, from which the printed
checks are formed, being carried in a suitably supported roll I³, Figure 2, and led
thence rearward into a guide-way J3 carried by the frame D³, thence passing
upward and forward between a pair of feed rollers R³ $3, Figures 9 and 10, thence
forward through a narrow slot T3 in a cross piece U of the frame B, and thence
forward over the plate E3 and platen F3. The feed rollers R³ S³ are geared to the
shaft E, so that at each revolution of the latter a given length of the strip is fed
forward over the plate while the latter is in its lower position. When it is
then lifted to its highest position it carries the strip against the type-carriers
and effects the printing, while a knife V³ secured to the rear end of the plate E
severs the printed check from the strip against the front side of the cross-piece U³
containing the guide-way T
The detached printed check thus formed may be removed from the plate E3 by
hand, but we have devised a novel ejector for automatically removing the check,
which may be now described: Mounted to slide backwardly and forwardly upon
the right hand inner edge of the plate E is a plate W3, Figures 7 to 10, whose
upper horizontal portion over-laps the top of the plate E3 some distance and slides
upon it, the plate having a depression formed in its upper side to accommodate
the over-lapping portion of the plate W. The plate W³ has projecting laterally
from its outer side a stud which fits in a long slot in the lower end of a curved
lever X3 fast upon a rock-shaft Y mounted in the frame B³. Mounted in a
bearing upon the left side of the lever X3 at the upper end of the slot therein
is a sliding rod or pin A+, surrounded within the bearing by a coiled spring
pressing against a shoulder upon the rod and yieldingly holding it in its normal
position shown in Figure 10. The front end of the rod A stands over the
plate W3, and is widened and serrated for a purpose to be explained. It will be
seen that if the lower forward end of the lever X be moved rearward the serrated
end of the rod A', moving in the arc of a circle struck from the pivot Y3 of the
lever, will engage the upper side of the plate W3, after which any further rear-
ward movement of the lever will cause the rod A* to be forced upward into the
bearing Z3 against the resistance of the spring surrounding it in such bearing.
Such rearward movement of the parts will therefore cause the rod A+ and plate W³
to grip anything placed between them, and if they are then thrown quickly for-
ward they will carry such object with them until they separate as they reach
normal position. Now, the front end of the paper strip as it is advanced by the
feed rollers R³ S3 at each operation of the machine passes over the plate W3, and
by means hereafter described the lower end of the lever X is moved rearward as

page_text: the plate E3 is being lifted to carry the platen F3 against the type-carriers and
cause the knife V³ to sever the check, and after the printing has been effected and
the check severed from the strip the lower end of the lever X is thrown quickly
forward, causing the rod A and plate W³, which have gripped the check
between them, to carry the check forward and eject it from the machine. The
upper rear end of the lever X3 has pivoted to it the lower end of the rod B' whose
upper end passes through a screw cap C which serves to confine a coiled spring
surrounding the rod. When the front end of the lever X³ is moved rearward, as
above described, this spring will be compressed, so that when the lever is released
its front end will be quickly thrown forward to eject the check. By providing
means for positively moving the lever rearward against the stress of the spring,
and then releasing it at the proper time, an operative automatic ejector would be
produced, but we have provided means for positively moving the lever in both
directions, and employ the spring merely as an auxiliary device, as hereafter
explained. As before stated, the lever X is fast upon the rock-shaft Y³, and the
latter has fast upon it near its left hand end, just within the outer wall of the
frame B³, a rearwardly projecting arm D, Figures 7 and S. Pivoted at E6 to a
stud upon the framework is a short lever F whose front end overlies and rests
upon the arm D. The shaft E has fast upon it a gear G4 which meshes with a
second gear H which in turn meshes with a third gear I', and the latter has upon
its side a laterally projecting stud 15 adapted, in the revolution of the gear, to
contact with the rear end of the lever F and rock the latter upon its pivot, as it
passes by and clears the end of the lever. The shaft E also has fast it a
upon
small cam Jadapted to co-operate with the arm D upon the rock-shaft, Y³.
Under this construction and arrangement the operation of the parts is as follows:
At each operation of the machine and revolution of the shaft E the cam J' will
ride under the rear end of the arm D and lift it, thereby rocking the shaft Y³
and throwing the lower end of the ejector lever X³ rearward and cause the grip-
ping devices to take hold of the check. Just as the tail of the cam J clears the
end of the arm 1 the stud upon the gear I will contact with the rear end of the
lever and throw it upward, forcing its front end downward and causing it to
depress the arm D and rock the shaft Y3 and throw the lower end of the lever X³
forward to eject the check. In this manner and by this means the ejector lever
is positively moved in both directions, and a spring action is not depended
upon as
the spring surrounding
The purpose of employing
the rod B heretofore described is this: If the machine should be
operated very slowly the lower end of the lever X3 might be moved forward so
slowly as to simply carry the printed check with it until the latter was released
by the gripping devices, instead of causing it to be thrown still further forward
by the momentum of the part, as is desirable. In such case the spring will
impart a quicker movement to the lever and cause the check to be properly
ejected; but under the usual operation of the machine the lever X will be posi-
tively thrown forward with sufficient speed to properly eject the check, in which
case the spring performs no essential part of the operation.
heretofore.
A suitable receptacle or hood, not shown, is placed in front of the printing and
ejecting mechanism, to receive the printed checks as they are thrown out. The
roll of the check strip is supported upon a stub-shaft A³ projecting from the
side of the machine, Figure 2, and held in place thereon by a segmental guard-
plate B pivoted at its lower forward corner to a shield C³ secured to the frame-
work. By throwing this guard-plate B³ forward the roll I may be slipped off the
shaft A5 or a new roll placed thereon, and upon then throwing the guard-plate 15
backward it will be held by gravity in normal position.
As before stated, there are two paper strips led over the type-carriers and
impression platen, the second of which is a record strip 15, Figures 2 and 9, which
is carried upon a supply roll E supported by a bracket F Fig. 10 depending from
the plate E3 and led thence upward through a slot in the plate ³, across the
platen F3 and thence downward through a second slot in the plate E³ and wound

page_text: around a storage reel G supported upon a second bracket extending forward and
downward from the plate E, and automatically actuated by means described in
Patent No. 18,079, to draw forward the paper strip- a given distance at each oper-
ation of the machine. The slots in the plate E at front and rear of the platen F³
extend outward through the edge of the plate, as seen in Figure 9, so that in
placing a fresh supply of record strip in the machine it may be slipped bodily side-
wise over the platen and does not have to be threaded endwise through slots in
front and in rear of the same as heretofore. There is provided a guard-plate I³
pivoted at its front end to the plate D3 and provided near its lower end with a
notch adapted to fit over a stud J. When the strip is to be removed or inserted
the lower end of this guard plate is pulled forward by means of a knob L³,
Figure 2, and after the strip has been removed or inserted the plate is pushed rear-
ward and its notch engaged with the stud J. To yieldingly hold the plate 15
in its rearward position there is confined in a housing upon the front edge of the
frame B or guide-way Ca spring plunger M5 whose outer end is beveled as
shown and stand in the path of the plate 1. When the plate is swung forward it
rides over the beveled edge of the plunger and forces the latter into its housing,
and the engagement of the plunger with the inner side of the plate yieldingly
holds the latter in forward position while the strip is being removed or inserted,
and when the plate is swung rearward again the plunger springs outward and
yieldingly holds the plate in normal position. The cam groove in the disk G3, by
which the impression plate is actuated, is so shaped, as shown and described in
Patent 18,079, that the platen is given two impressing movements at each oper-
ation of the machine, the first effecting the printing upon the paper strip or check,
after which the check is automatically ejected by the means described, and then
before the strip is advanced for the next check the platen is given its second move-
ment to effect the printing upon the lower or record strip, as fully described in
the aforesaid patent.

vention and in what manner the same is to be performed, I declare that what I
