Improvements in or relating to Cash Registers.
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:-
The present invention will be illustrated and described as an improvement upon
a well-known style of cash register now in extensive use; but some of its features
are applicable to other styles of machines, as will be understood from the descrip-
tion given of the invention. The principal feature of the invention relates to
the employment in the machine of a series of special registers or counters appro-
priated to different special purposes, and their novel combination with the main
totalizing cash register of the machine, and with the operating devices of the
machine; all as will be hereafter more fully explained and particularly pointed
out in the claims.

page_text: The same letters of reference are used to indicate identical parts in all the
figures.
As in the prior machines of this style, the driving mechanism is operated by a
rotary handle A, Figures 1 and 3, which is fast upon the end of a stub shaft which
has secured upon it a gear B meshing with a second gear C, which latter in turn
meshes with a third gear D) which meshes with a fourth gear E fast upon the right
hand end of a rotary shaft F, Figures 3 to 7, which extends entirely across the
machine near its rear side, and has interposed in it near its left hand end a
crank G, Figure 3, to which is connected the upper rear end of a pitman H whose
lower forward end is connected to an arm I, Figure 7, fast upon a rock-shaft J
extending from side to side of the machine in the lower middle portion thereof
and suitably journaled in the framework. Under this arrangement of the parts
each revolution of the operating handle A rocks the shaft J forward and backward
a definite distance.
In the present instance the machine is shown provided with four rows or banks
of keys K, Figures 1 and 2, representing respectively units of cents, tens of cents,
units of dollars and tens of dollars, and there are loosely mounted upon the rock-
shaft J four gear-toothed segments L, Figures 5, 6 and 7, one for each row of keys
and arranged approximately in line therewith. Interposed between the respective
segments L and the rock-shaft J are suitable latches or connecting devices which
co-operate with the inner ends of the keys K in such manner that when a key in
any given row is pressed in and the operating handle of the machine given a
revolution the rock-shaft J at the end of its forward movement will become con-
nected to the segment corresponding to such row of keys, and will carry the seg-
ment with it, as it moves backward, until the segment becomes disconnected from
it by the inner end of the operated key, so that in its backward movement the
shaft carries the segment with it a distance proportionate to the position and the
value of such key. At the next operation of the machine the rock-shaft at its
forward movement will pick up the segment at the point where it left it in its
previous backward movement, and will carry it on forward again to the end of
its forward movement, and if no key in the row corresponding to this segment
has been pressed in at such second operation of the machine the segment will
remain in such forward position and the rock-shaft will return to normal position
alone. The particular means illustrated in the drawings for accomplishing the
results just described are illustrated and explained in detail in the application
before referred to, while other forms of similar devices for the same purposes are
shown and described in various prior patents. It will therefore be unnecessary to
further refer to them here.
Each of the segments L meshes with a large gear wheel M mounted upon a
shaft N above and in rear of the segments, Figures 4, 5 and 6, and each gear M
meshes with a pinion O fast upon the sleeve or hub of an indicator wheel P loose
upon a shaft Q. The movements of the segments L will be thus transmitted to
the indicator wheels P, so that when any segment is carried by the rock-shaft
until it is disconnected therefrom by some one of the keys its indicator will be
moved until the number representing the value of such key is brought to the
indicating point, while when the segment is moved to its extreme forward position
the indicator will be moved to position to expose its cipher at the indicating
point. In the machine illustrated in the drawings there are employed eight indi-
cator wheels, four arranged to effect the indication at the front of the machine,
and four to effect it at the rear. The respective wheels are geared together in the
manner described in the aforesaid application to accomplish this result.
Each of the gears M (or segment fast upon its hub as in Figure 5) meshes with
a pinion R, Figure 4, loose upon a shaft S journaled in the framework in front
of the gears M and extending from side to side of the machine. Each of the
pinions R has fast upon its side a smaller pinion T, Figures 2 and 4, while loose
upon the shaft $ beside such pinion T is a pinion U, of the same size, fast upon
the side or hub of one of the registering wheels V. Fast upon a rock-shaft W

page_text: journaled in the framework in front of and below the pinions above described
are a series of upwardly extending arms X, Figures 4, 5 and 6, each of which
carries an idle pinion Y standing in line with a pair of pinions T U. When the
idle pinions Y are thrown rearward, by rocking the shaft W, into mesh with the
pinions T U, each pinion T will become geared to the adjacent pinion U and its
registering wheel, so that any movement imparted to the pinion T from its driving
segment L will be transmitted to the pinion U and registering wheel. By means here-
after described the shaft W is rocked backward and forward at each operation of the
machine in such manner as to cause the idle pinions Y to mesh with the pinions TU
during the backward movement of the rock-shaft J, so that any movement im-
parted by said shaft to any of the segments during its backward movement wili
be transmitted to the corresponding registering wheel, so that the amount indicated
by the indicator wheel at such operation will be added upon the registering
mechanism. The rock-shaft W has fast upon it a short depending arm Z
Figure 5, to which is connected the front end of a rearwardly extending arm A¹
whose rear end is slotted and embraces the shaft F, and which is provided in
front of said shaft with a latterly projecting stud B' which fits in a cam groove in
a disk C fast upon the shaft F, with the result that at each operation of the
machine and revolution of the shaft F the idle pinions Y will be rocked backward
and forward at the proper times for the purpose above mentioned. When in
their forward position the pinions Y are locked from movement by the engage-
ment with them of fixed locking dogs D¹ fast upon a rod secured in the frame-
work. It will be understood that the idle pinions Y stand out of line with the
pinions R, and do not mesh with the latter as might seem to be indicated in
Figures 4 and 5.
So much of the machine as has been above described is substantially the same
as that illustrated in the aforesaid application, and the explanation which has
been given of it will be sufficient for an understanding of my present invention.
In the present instance the special registers or counters to which the principal
feature of my invention relates are six in number, arranged in two sets of three
each, and there are employed in connection with them six special keys, three
upon either side of the machine, as shown in Figures 1, 2 and 8. These six special
registers and their respective keys may be employed for any six different purposes
desired, as, for instance, for preserving separate records of the sales of six different
classes of goods, or sales from six different departments of a store, or of sales by
six different clerks, and so on. In the present instance, however, the three
registers in the left hand set and their three co-operating keys are employed to
separately register sales made by three different clerks, designated A, B and C by
those letters upon the key-buttons, while the three registers in the right hand set
are employed to register three separate classes of transactions, one being money
paid out on account, another being money received on account, and the third
being goods sold on credit, and the key-buttons bear respectively the words "paid
out," R. on Acc't." and "Credit. The general operation of the machine with
these several special registers consists in pressing in the proper cash keys K,
representing the amount of the transaction, then pressing in one of the keys A,
BC, to cause the amount of the sale to be registered in the counter belonging to
the clerk making the sale, or, if the transaction is not a cash one or is not a sale,
one of the three special keys at the right will be pressed in, instead of one of the
clerks keys; and then the main operating handle of the machine will be given
a complete revolution. Under this arrangement of the special registers it is
desirable that the cash sales made by all three of the clerks A B and C shall be
added into the common total on the main register of the machine heretofore
described, while it is desirable that the amounts added upon the three special
registers at the right side of the machine shall not be added upon such main
register. To this end it is necessary that when any one of the clerks keys ABC
is pressed in the corresponding special register shall be thrown into connection
with the driving mechanism, and both such special registers and the main register

page_text: of the machine be actuated by such driving mechanism; while, on the other hand,
when either one of the special keys at the right of the machine is pressed in it
is necessary that the corresponding special register shall be thrown into connec-
tion with the driving mechanism, while the main register of the machine is thrown
or maintained out of connection with such mechanism, so that when the operating
handle is turned such special register will be actuated by the driving mechanism,
while the main register of the machine will not be actuated. I have provided
novel means for accomplishing these results and bringing about this mode of
operation, which will be explained in connection with the following detailed
description of the special registers and the means for actuating them.
Secured to the lower forward part of the main framework of the machine is a
supplemental frame consisting of two side plates E F¹, of the shape shown in
Figures 1 and 2, and a cross-bar G¹ connecting their lower forward corners.
Journaled at its opposite ends in the plates E¹ F¹ near their rear edges is a shaft H¹,
upon which are loosely mounted eight segments, four at each side of the middle
of the machine, Figure 9. Of these eight segments the extreme right hand one I¹,
Figures 6 and 9, is connected by a link I to a pendent extension of the right hand
one of the four segments L, so that the movements of such segment L will be
imparted to the segment I. The second segment J' is similarly connected to the
second one of the four segments L, so that the movements of such second segment L
are imparted to the segment J². The two segments O¹ and P¹, at the extreme left
of the series of eight, are respectively connected in a similar manner with the
third and fourth segments L, so that the movements of such third and fourth
segments L are imparted to the segments 01 and P. By suitable intermediate
sleeves and connecting arms not necessary to be described in detail, Figure 9, the
segment I¹ is rigidly connected with the segment M¹, so that the movements im-
parted to the segment I¹ by the segment L with which it is connected are trans-
mitted to the segment M¹, the segments I¹ and M¹ being rigidly connected
together and moving in unison. The segments J¹ and N¹ are likewise connected,
so that the movements imparted to the segment J¹ by its connected segment. L
will be transmitted to the segment N¹. The segments K' L' are likewise
respectively connected with the segments 01 P1, which latter, as before explained, are
connected by links to the third and fourth segments L respectively, so that the
movements imparted to such segments 01 P¹ by their connected segments L will
be transmitted to the segments L' K¹.
Under this arrangement and connection of the parts we have mounted in the
supplemental frame, upon the shaft H³, two separate supplemental sets of seg-
ments, each containing four segments connected respectively to the four main
segments L of the machine, with the result that when any one of said main
segments L is moved the corresponding segment in each of these supplemental
sets will be likewise moved.
Mounted in a curved frame Q¹, Figure 10, over each of these sets of supple-
mental segments are three trains of registering wheels, constituting the special
counters or registers before referred to. As seen in Figures 4, 6, 11, and 12,
each train of wheels is mounted upon a shaft R' supported at its opposite ends
in the side arms of a frame S¹, pivoted at a between the side plates of the frame Q¹.
Secured to the sides or hubs of the first four wheels in each train are pinions U¹
adapted to co-operate with the supplemental segments. By means of suitable
springs T, Figure 11, the frames S¹ are normally held in such position that the
pinions U are out of mesh with their respective segments, as seen in Figures 6,
11 and 12, but these springs permit the ends of the frames S¹ carrying the trains
of the wheels to be pressed inward toward the segments and the pinions U
brought into mesh with the segments, so that the latter may drive the registering
wheels. It will be understood that if any particular train of wheels in either set
be thus thrown into gear with the segments of such set the wheels of that par-
ticular train will be actuated by any of the segments that may be moved at the
ensuing operation of the machine, while the remaining trains of wheels, whose

page_text: pinions are out of mesh with the segments, will not be moved. The several special
registers are therefore placed at will in connection with the driving mechanism
by rocking the pivoted frames S¹ in which they are carried into position for their
pinions U to mesh with the supplemental segments, and this is accomplished by
means of the several special keys corresponding to the special registers, in the
manner and by the means to be now described.
Secured to the curved outer edge of the right hand plate E¹ of the supplemental
frame is a plate V₁, Figures 1, 4, 6, 6, and 8, in which are mounted radially to
the shaft H the three special keys which co-operate with the three registers in
the right hand set, while secured to the opposite side plate F1 of the supplemental
frame is a similar curved plate W₁, Figures 2, 7 and 8, in which the three special
keys co-operating with the left hand set of special registers are mounted. The
inner ends of the special keys in each set are guided in a fixed curved plate X¹,
Figures 6, 6, 7 and 9, concentric to the shaft H¹ and secured to the adjacent side
plate E or F of the supplemental frame, while interposed between such plate X¹
and pins Y passed through the stems of the keys are coiled springs Z¹ surround-
ing the key stems and serving to press the keys outward and yieldingly hold them
in normal position. Loosely mounted upon the shaft H¹ between each plate X¹
and the adjacent side plate of the framework is a detent plate A2, Figures 6, 7, 9
and 9, curved concentrically to the shaft H', and pulled downward and yield-
ingly held in its lower normal position by a coiled spring B2. Each of theso
detent plates is provided with three passageways for lugs Cupon the sides of
the key stems, such passageways being of the shape shown in Figure 94, the upper
rear wall or side of each passage way being beveled or inclined downwards
and forwards for a short distance, such beveled or inclined portion terminating
in an abrupt shoulder b, whence the wall of the passage way continues in a line
radial to the shaft H¹; while the lower forward wall of each passage way consists
of a plain beveled or cam surface from the upper to the lower end of the passage
way. When any key is pressed inward a slight distance its lug C, Figures 6*
and 7, bearing against the inner surface of the upper side of the passage way,
will press the detent plate A³ upward and rearward, against the stress of the
spring B2, until the lug C³ clears the shoulder b, whereupon the detent plate will
be pulled forward and downward by the spring and the shoulder will catch over
the lug and hold the key in such slightly depressed position, with its lug
beneath the beveled surface c of the lower forward wall of the passage way and in
the path thereof when the detent plate A2 is pulled rearward. The rear end of
the detent plate A2 has pivoted to it the forward end of a long curved arm D²,
Figure 7, whose rear end is slotted and embraces the shaft F, heretofore described.
The extreme rear end of the arm D³, in rear of the shaft F, is provided with a
laterally projecting stud F which stands in the path of a cam F3 fast upon the
shaft F, with the result that at each operation of the machine and revolution of
the shaft F the arm D2 will be forced rearward by the cam F, and the detent
plate A be drawn in that direction. If, prior to such rearward movement of the
detent plate A3, any one of the special keys has been depressed until its lug C³
has been caught by the shoulder 6 in the passage way in the detent plate the
beveled forward wall c of the passage-way will ride over the lug of such key
as the detent plate is drawn rearward, and will force the key inward to its limit
of movement. When the cam F2 clears the stud on the arm D2 and releases
the latter, toward the end of the operation of the machine, the spring B2 will
immediately draw the detent plate A³ forward and downward, thereby releasing
the key which had been pressed in and permitting its spring 7 to throw it out
to normal position again. Now, each of the pivoted frames S₁ carrying the special
registers has secured to its end adjacent the row of special keys co-operating with
such set of registers an arm G³, Figure 11, which has a projection H which stands
in the path of the projecting pin Y' of one of the special keys co-operating with
such set of registers, so that when any one of such keys is pressed in to its limit
of movement in the manner above described its pin Y₁ will press inward the train

page_text: of registering wheels corresponding to such key and carry their pinions U¹ into
mesh with the supplemental segments, and the adjustment of the parts is such
that this engagement of the pinions with the segments will be effected by the
action of the cam F2 at the end of the forward movement of the segments or very
beginning of their backward movement, while the detent plate will be released
and restored to normal position by the spring 132, and the depressed key be likewise
thrown out of normal position by its spring Z' at the end of the backward move-
ment of the segment, so that the special register will be in gear with the supple-
mental segments during only their backward registering movements, and in this
manner the registering movements of the main segments will be transmitted to
the special register, while their return or resetting movements are independent of
such registers.
For the purpose of normally locking the special registers out of engagement
with the supplemental segments, and preventing each of them from being thrown
into engagement with such segments except when the special key corresponding
to the register to be engaged with the segments is first operated or set, there is
loosely mounted upon the shaft H' at such side of the machine, immediately
adjacent the inner side of the fixed guide-plate X' in which the extreme inner ends
of the keys normally fit, and through which they are projected when the keys
are pressed inward, a segmental locking-plate I2, Figures 6, 6 and 9 which has
three locking projections J2, one of which, in the normal operation of the parts,
Figure 6, stands immediately in the path of the projection H2 of the arm G² of
each of the pivoted frames S¹ in which the special registers are mounted as before
explained. So long as this locking plate I remains in normal position, therefore,
it is not possible to press any one of the special registers inward and engage its
pinions U with the supplemental segments. When, however, any one of the
special keys belonging to the set is pressed inward the locking plate 12 is moved
so as to carry its locking projection J2, which stands in the path of the special
register corresponding to such key, out of the path thereof, and thus permit the
register to be pressed inward into engagement with the segments. To this end
each locking plate 12 is provided with three pins K2, Figures 6, 6 and 7, projecting
laterally from it immediately beneath or inside the adjacent guide-plate X', (dotted
line Figure 9) each of which pins stands in the path of one of the special keys,
whose inner ends are beveled as shown, so that when either one of the keys is
pressed inward its beveled inner end will engage one of the pins K and rock the
plate 12, rearward, against the stress of a spring L2 connected to the plate and
yieldingly holding it in normal position. This rearward movement of the plate I³
will carry its locking projections J2 out of the path of the projections H2 of the
arms G2 of the special registers, so that the register corresponding to the operated
key may be pressed inward, in the manner and by the means heretofore explained,
to engage its pinions with the segments.
With only the mechanism so far described it will be understood that when any
one of the special keys was pressed in the corresponding special register would
be engaged with the supplemental segments, and at the ensuing operation of the
machine the amount indicated by the indicators and added upon the main register
of the machine would also be added upon such special register; and this is true
in the case of the three special registers in the left hand set, which registers are
appropriated to three clerks A B and C and are employed to separately register
the cash sales made by said clerks respectively. In the present instance, however,
the three special registers in the right hand set are not employed to register cash
sales but, on the contrary, to register credit sales, and amounts received on account
and amounts paid out. It will therefore be understood that the amounts registered
upon the three special registers of this right hand set must not be added upon the
main cash register of the machine, and I have provided means for maintaining
the main register of the machine out of connection with the driving mechanism
of the machine whenever any one of the special keys in the right hand set is
pressed in and its corresponding special register engaged with the right hand set

page_text: of supplemental segments. It has been heretofore explained that the registering
wheels of the main register are thrown into and out of gear with the main actuating
segments L by means of the idle pinions Y which are carried by the arms X
fast upon the rock shaft W, Figure 5, which shaft is rocked at the proper times
in the operation of the machine by an arm A which is connected at its forward
end with a short arm Z fast upon said shaft, and fits at its rear end over the
shaft F and is provided with a stud 11 fitting in a cam groove in a disk C¹ fast
upon said shaft F. If the front end of the arm A¹ were simply pivoted to the
arm Z of the rock-shaft W the pinions Y would necessarily be thrown into and
out of mesh with their co-operating pinions T U at each operation of the machine,
to gear the registering wheels with and ungear them from the driving mechanism,
and this was the case in the machine of the prior application referred to. In the
present instance, however, the front end of the arm A¹ is connected to the lower
end of the arm Z by a projecting pin or stud L2 upon the arm Z fitting in a sort
of L-shaped slot M2 in the arm A¹. In the normal position of the parts the pin
upon the arm Z fits in the upper end of this L-shaped slot, as seen in Figure 5,
sc that any backward and forward movement of the arm A' will rock the shaft W;
but it will be understood that if the front end of the arm A¹ be lifted until the
lower horizontal portion of the slot M² is brought into horizontal line with the
pin L on the arm. Z the arm A¹ may be moved backward and forward without
rocking the shaft W. Now, the front end of the arm A¹ is so connected with the
operating devices of the special registers in the right hand set that whenever any
one of such registers is pressed inward and engaged with the supplemental seg-
ments the front end of the arm A¹ is lifted and held in such lifted position during
the operation of the machine, so that the shaft W will not be rocked and the
pinions Y not engaged with the pinions T U, and the registering wheels of the
main register therefore not actuated. As seen in Figure 5 the arm A¹ is pro-
vided in rear of the slot M2 with a second slot in which fits a pin carried by the
upper end of a long arm N2 which is fast at its lower end upon a rock-shaft 02
suitably journaled in the frame-work. At its extreme right hand end this rock-
shaft has fast upon it a depending arm P2, Figures 6 and 6, whose lower end
stands in the path of rearward movement of the locking plate I³ of the right hand
set of special registers, so that when any one of the special keys in the right hand
set is pressed inward and said locking plate forced forward, in the manner hereto-
fore explained, the rock-shaft 02 will be turned slightly in the direction of the
arrow in Figure 5, and the upper rear end of the arm N2 be thereby thrown
slightly upward, and the front end of the arm A¹ lifted into position to permit
it to move forward and backward without affecting the rock-shaft W, as before
explained. Inasmuch as the locking plate I will be held in rearward position by
the operated key until such key is released and thrown outward to normal position,
and inasmuch as such key is not released until nearly the end of the operation of
the machine, it follows that when any special key in the right hand set is pressed
in, to engage its corresponding special register with the supplemental segments,
the connecting devices between the driving mechanism and the main register of
the machine will be thrown out of operative position, and will be maintained out
of operative position during the ensuing operation of the machine, so that the
amount indicated at such operation of the machine will be added only upon such
special register.
For the purpose of necessitating the operating of some one of the six special
keys before the main operating handle of the machine can be turned there is pro-
vided a locking device for the driving mechanism, which normally locks it from
movement, but unlocks it whenever any of the special keys is operated. This
locking device consists of a rock-shaft Q³ extending transversely across the rear
side of the machine and suitably journaled in the framework, Figure 3, and
having fast upon it an upwardly extending arm R² which is provided at its upper
end with a hook co-operating with a shoulder upon the periphery of the disk C,
Figure 5. So long as the parts are in the position shown in Figure 5, the arm R³

page_text: will lock the disk C¹ and shaft F from turning, and consequently prevent any
operation of the machine. Near its opposite ends the rock-shaft Q is provided
with two additional upwardly extending arms S³, Figures 3, 6 and 7, the upper
ends of which arms rest against or stand in the path of the rear ends of the arms D²
whose forward ends are pivoted to the detent A³ and whose rear ends co-operate
with the cams F2 upon the shaft F, in the manner heretofore explained. When
any of the special keys in either set is pressed in the detent plate A³ of such set
is forced slightly rearward, which rearward movement is imparted to the arm D³
connected to such detent plate, and the extreme rear end of such arm will engage
the upper end of the arm S2 of the rock-shaft Q2 and force the upper end of each
arm slightly rearward, thereby rocking said shaft and throwing the upper end
of its locking arm R³ rearward and disengaging it from the shoulder of the disk C³,
thereby unlocking the driving mechanism.
The transfer devices between the registering wheels of the special registers are
as follows: There is loosely mounted upon the shaft H¹ midway between the two
sets of special registers a rocking frame A³, Figures 4, 5, 8 and 9, to whose upper
and lower ends are secured two transverse bars B³ whose opposite ends project
laterally across the two sets of special registers as seen in Figures 1, 2 and 8.
Secured to and carried by the opposite ends of these cross bars B³ are two sets
of curved arms or plates 0%, there being three of such curved arms in each set.
The two cross-bars B³ and the two sets of curved arms C3 are rigidly secured to
the frame A³ hung upon the shaft H¹, and with said frame A³ constitute a rock-
ing frame mounted on said shaft. Pivoted to the upper end of the frame A³ is
the forward end of a long curved arm D³, Figures 4 and 5, whose upper rear end
is curved to the right and at its upper extremity is hung upon a stud E³. A
short distance below the stud E³ the arm D3 has secured upon its side a plate or
block F3 which stands in the path of a cam G³ fast upon the shaft heretofore
described. At each operation of the machine and revolution of the shaft F the
cam G³ will engage the plate F³ and force the arm D³ rearward thereby rocking
the frame A³ and parts carried by it upward and rearward. A coiled spring H³
connected to the arm D³, Figure 4, resets said arm and the frame A³ as soon as
the cam G³ clears the plate F3 on said arm. In this manner and by these means
the frame A3 and parts carried by it are rocked upward and rearward and then
returned to normal position at each operation of the machine. Now, the transfer
pawls 13 are carried by the curved arms C3 of the rocking frame, Figures 4, 4*
and 8, being pivoted to the sides of said arms in position to co-operate with the
ratchets upon the hubs of the registering wheels, each of the four right hand
wheels in each train being provided not only with a pinion U₁, as heretofore
described, but also with a ratchet J³ and a disk K³ having upon its periphery a
single tooth or projection, Figure 12, as usual. Each of the transfer pawls 1³
(except the upper ones) is provided at its lower end with two notches which
co-operate with a spring-pressed detent L³ confined in a housing secured to the
side of the arm C, and between such end and its pivot the pawl is provided with
a notch or cut-away space which forms a shoulder M³. The ratchets of the register-
ing wheels stand out of the path of travel of the engaging ends of the pawls I³
so long as said pawls remain in the normal position shown upon their respective
arms C³, but when the engaging end of any pawl is pressed inward toward the
registering wheels, until the inner one of the two notches in its lower end engages
the detent L³, such pawl at the next rearward movement of the rocking frame
will engage the ratchet of its registering wheel and advance the latter the space
of one tooth, to add a unit of value upon such wheel. Mounted in each of the
pivoted registering frames S₁ between the pivotal support of such frame and the
train of wheels carried by it, is a rod N³, Figures 4ª, 6, 11 and 12, upon which
are mounted a series of spring-pressed holding pawls 03 engaging the ratchets
of the respective wheels to prevent backward movement of the latter. Mounted
upon the rod N³ between the holding pawls 03 of the first four registering wheels
are a series of sleeves P³, Figures 10 and 12. Each sleeve at its right hand end

page_text: is provided with a rearwardly projecting arm Q³ which stands in the path of travel
of the single tooth or projection of the disk K³ upon the adjacent registering wheel,
Figure 12, while at its left hand end such sleeve is provided with a projection R³
in line with the transfer pawl I³ of the next higher registering wheel in the series,
Figures 10 and 12. Now, the projection R³ upon such sleeve normally stands
out of the path of travel of said pawl, but when the sleeve is rocked upon the
rod N³ the projection R³ will be thrown outward into the path of travel of the
pawl, the sleeve being frictionally held in its different position. As each register-
ing wheel completes a revolution the tooth or projection of its disk K³ will engage
the arm Q3 on the right hand end of the sleeve P³ interposed between such wheel
and the next higher wheel, and as the tooth of the disk K³ rides over and clears
the arm Q³ it will rock the sleeve P³ and throw the projection R³ outward into the
path of the shoulder M³ of the transfer pawl, so that at the upward rearward move-
ment of such pawl, as the rocking frame is moved in that direction, the shoulder M³
will contact with the projection R³ and the lower end of the pawl be forced out-
ward and its upper end thrown inward into position to engage the ratchet of its
registering wheel, so that the further rearward movement of the pawl will turn
said wheel and effect the transfer. As the pawl approaches. the end of its move-
ment the ratchet will have been turned so that the face of the ratchet tooth which
is engaged by the pawl will present an inclined surface to the end of the pawl,
and as the latter completes its movement it will ride up over said surface and be
thereby rocked upon its pivot back to normal position, its upper rear end being
thrown outward and its lower forward end inward, so that the spring detent L³
re-engages the outer notch in its lower end. As the pawl-carrying frame and
pawls move backward (downward and forward) to normal position again the lower
end of the pawl will contact with the outwardly projecting point R3 of the sleeve
and rock the latter back to normal position, so that all the parts will be reset at
the end of their backward movement.
It will be seen that the transfer pawls for the upper trains of registering wheels
in each set are placed in reverse position to that of the lower pawls, and provided
with hooked ends to enable them to properly co-operate with the ratchets. This
difference in arrangement is necessitated by the fact that the pivoted frame S¹
carrying the upper train of wheels in each set is placed in reverse position to that.
of the frames carrying the two lower trains of wheels, being pivoted in the fixed
frame at its extreme upper rear end, while the frames of the lower trains of wheels
are pivoted in the fixed frame at the extreme lower forward ends.
Interposed between the registering wheels of each train and the rotary shaft R¹
upon which the wheels are mounted are the usual or any suitable devices for
causing the rotation of the shaft in one direction to pick up the registering wheels
and return them to initial position, and for the purpose of simultaneously reset-
ting all the wheels in either set the following means are provided, reference being
had for convenience to the right hand set of special registers: Fitting against the
inner or right hand face of the left hand side-plate of the fixed frame Q in which
the special registers are mounted, between such side-plate and the adjacent ends
of the pivoted frames in which the special registers are carried, is a curved
segment S3, Figures 11, 12 and 13, provided upon its periphery with gear teeth
adapted to mesh with pinions T3 fast upon the extreme left hand ends of the
shafts R' upon which the wheels are mounted. This segment is mounted to turn
upon the shaft H', in the present instance fitting over the sleeves upon said shaft,
and is mounted upon said sleeves by an open slot which permits it to be slid out-
ward and inward toward and from the axis of the shaft H. In its outer position
the teeth upon its periphery mesh with the pinions T3, while in its inner position
they are disengaged from the pinions. The inner face of the side-plate of the
frame Q against which the segment fits is provided with two curved grooves S
communicating with each other at their opposite ends, Figure 13, in which fits
a stud or pin U³ upon the side of the segment S³, with the result that when the
segment is pulled outward and engaged with the pinions, and then moved forward

page_text: to turn the pinions and shafts and reset the registering wheels, the pin will travel
in the upper or outer grooves, and guide the segment in its movement, and when
at the end of its forward movement, after the wheels have been reset, the segment
is pressed back inward and moved rearward the pins will travel in the lower or
inuer groove and guide the segment in its rearward movement. The segment has
secured to its left hand side an operating handle 3 which fits against the left
hand side of the plate Q¹ of the fixed frame, said side plate being embraced between
the segment and this handle. In resetting the registers this handle is grasped
and the segment drawn outward or radially away from the shaft H¹ until it is
brought into mesh with the pinions 13, and the handle is then pulled forward to
its limit of movement, whereupon, at the release of the handle, a spring W³ con-
nected to the segment will draw the latter inward toward the shaft A¹ again and
then carry it backward to normal position.
