Improvements in Cash Registers and Indicators.
1, HERBERT JOHN HADDAN, of the firm of Herbert & Co. Patent. Agents of
18 Buckingham Street, Strand, W.C. London in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention a communication to me
from abroad by The National Cash Register Company, of Dayton, in the 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 invention relates to improvements in cash registers and indicators designed for
the use of store-keepers and others, and has for its object an improvement in that
class of machines. Its novelty will be herein set forth and specifically pointed out in
the claims.
In the accompanying drawings
Figure 1 represents a side elevation of a portion of a well known form of cash
register having my improvement applied thereto and having the rear side of the case
or cabinet removed and a portion of the frame-work broken away and some of the
operating parts on the opposite side of the machine removed.
Figure 2 is a sectional side elevation of the lower and rear side of the machine, and
showing the parts not illustrated in Figure 1.
Figure 3 is a rear elevation of a portion of the machine.
Figure 4 is a detail of the locking-bar and the rear ends of the keys.
Figure 5 is a detail of the arresting devices for the vibrating bar.
Figure 6 is a detail of the wiper-block and tripping-dog for actuating the wing.
The same letters of reference are used to indicate identical parts in all the
figures.
"The frame-work A, which supports the working parts of the machine, is inclosed in
the usual case or cabinet B, having in its lower portion a drawer-compartment, in
which is fitted a money-drawer or till C.
Dare the operating-keys pivoted on the shaft E, their front ends projecting through
slots in the front of the case B, and provided with numbered finger-buttons, while on
their rear ends rest the usual tablet-rods F, carrying numbered indicating-tablets at
their upper ends and provided with shoulders a, which are engaged by the supporting
wing G to hold up an elevated tablet-rod in the usual manner. The wing G has at
one side an upward extension H, which carries the gong-hammer, and is provided
with a wiper-block b, engaged upon the operation of a key by the tripping-dog c,
carried on the upper rear end of the bell-crank 1, which is pivoted, as at i, to the
frame A of the machine, and at its lower forward end is connected by slot and pin
connection at e to the one of the side arms Jon the vibrating bar or frame K which
extends across all the keys and is moved by the operation of any one of them to
actuate the wing I and gong-hammer through the medium of the bell-crank and
tripping-dog e in the usual well-known manner. A flat spring, bearing on the
extension Hat one end of the wing, and at the other end a coiled spring g, connected
to an upwardly-extending arm h, secured to the wing and to a fixed point of the
frame-work, serve to yieldingly hold the wing G, extension H, and gong-hammer in
their normal positions. Pivoted to and depending from a lug i, extending rearwardly
from the wing G, is a link L, the lower end of which is pivoted to the outer end of
the lever M, which is pivoted to a support at j, Figure 3, and carries at its inner end
the locking-bolt N, which, when the drawer is closed, engages the slotted locking-
plate O, secured to the upper rear side of the drawer, and holds the latter in its closed
position. When a key is operated and the wing G pressed backward through the
inechanism before described, the link Land outer end of the lever M are depressed
the inner end of the lever M lifted, and the bolt N freed from the locking-plate O,
whereupon the drawer is propelled from its compartment by the spring P.

page_text: The registering mechanism may be of any suitable character; but in the machine
illustrated in the drawings it is of one of the usual well-known forms employed in
such machines, consisting of two banks of individual registering wheels (shown in
dotted lines in Figure 1) carried on longitudinal shafts supported in a supplemental
frame Q, the squared ends R R of which shafts are shown in Figure 1. The wheels
of the lower bank are actuated by the weighted dogs k, pivoted to the keys D, and the
wheels of the upper bank are actuated by and register the revolutions of those of the
lower bank in the well known manner.
Heretofore in this class of machines the vibrating bar K has been hung by its side
arms Jon the pivotal shaft E of the operating-keys, and its principal function was to
furnish a common actuator for the supporting-wing and the gong-sounding and
drawer-locking mechanisms. In my present improvement I give this bar additional
functions to perform the first arises from so constructing and arranging it and com-
bining it with the operating-keys as to constitute it a key-coupler which locks together
all keys which are displaced from their normal position at substantially the same time
and compels uniform movement in their further operation. For this purpose I hang
the bar K by its arms on a shaft S, located above and in rear of the pivotal point of
the keys, and provide the lower rear edge of the bar K with a rearwardly extending
flange, extending its entire length and resting on the upper sides of the keys. The
upper side of each key, just in rear of the flange 7 of the bar K, is provided with a
slotted lug, which forms a hook m, whose open mouth is in close proximity to the rear
edge of the flange 1. It results from this construction and the pivotal arrangement of
the bar K above the keys D that when a key is operated the Hange will enter the
mouth of the hook m and the key be thereby locked to the bar K, as shown by the
dotted lines at 1 in Figure 1. If two or more keys are started at the same time, they
will all become locked to the bar K in the same manner, and if any key-button is
released by the operator its key will be carried on down and the registration of its
value effected by the depression of the other key or keys which were started
with it.
Another feature of my invention consists in combining a key-arrester with a
movable bar, which extends across a series of keys and is moved by the operation of
any one of them, and, further, in combining such bar and arrester with a series of
keys which are so constructed that each of them becomes locked to said bar when
partially operated, for it will be evident that if the keys are locked to said bar from
the time they are displaced from their normal position until they are returned to such
position, and a key-arrester be applied to said bar in such manner that the bar is
arrested and held at any point where the key is released before full operation and
cannot be reset until the key is fully operated a single key-arrester so combined with
such bar will act as a common arrester for all the keys and prevent the resetting of
any one of them, when partially operated, until it has been operated to its full extent.
As one form of such arrester, and as a suitable method of combining it with such
bar, I have secured to one of the side arms J of the bar K a notched plate or rack T,
having downwardly-presenting teeth. Pivoted to the frame A at a point above this
rack is a bell-crank U, whose lower vertical arm n is provided with a shoulder o,
which, owing to the weight of the horizontal arm p of the bell-crank and the pivotal
arrangement of the latter, normally bears against the rack T, and when the latter is
lifted by the operation of a key and the lifting of the bar K slips over and acts as a
pawl for engagement with the teeth of the rack, so that if the key and bar be released,
at any point in their upward travel the shoulder o will engage a tooth of the rack T
and hold the bar K and the key which is locked to it at exactly the point where they
were released. Projecting laterally from the side arm.) in rear of the rack T is a
pin which as the key and bar K reach their full limit of upward motion, strikes the
under side of and lifts the horizontal arm p of the bell-crank U, as shown by the
dotted lines at 2, Figure 1, and throws the vertical arm away from the rack T,
thereby disengaging the shoulder o from the teeth of the rack.
V is a weighted latch for holding the arm and shoulder o away from the rack
until the key and bar K are reset. It is pivoted. at to the frame-work A, and its

page_text: upper rear ends has a lateral projection or is made of such width as to extend beneath
and bear upward against the under side of the arm J, as shown in Figure 5, being
normally held in such position by the gravity of its enlarged and weighted opposite
end. When a key is operate. and the bar K and arm J lifted the forward weighted
end of the latch drops upon the stop-pin t, causing the latch to assume the position
shown by the dotted lines in Figure 1. As the operation of the key continues and the
arm Jis lifted and the piny strikes the under side of the arm p of the bell-crank U
and throws its arm a away from the rack T, the lower end of the arm n flips over
the upper rear ends of the latch V and is held by it in the position shown by the
dotted lines in Figure 1 until, as the operated key and the bar K and arm J return
to their normal position, the under side of the arm J strikes the upper rear ends of
the latch Vand moves the latter back to the position shown by the solid lines in
Figure 1, thereby releasing the arm which then falls by gravity against the rack T,
ready for a fresh operation. It results from this construction and arrangement that
whenever any key is substantially displaced from its normal position it cannot be
returned to such position until it has been operated to its full extent and its total
value registered. This feature of my invention, therefore, while useful in a machine
provided with a series of individual registering wheels-one for each key and each
turned one number by the operation of its key, as above described-is perhaps more
valuable in a machine provided with a registering wheel common to and actuated to
different degrees by a series of keys of different values, for in such machines it is
absolutely essential to accurate registration that each key operated he actuated to its
full extent. So far as this feature of my invention is concerned I do not wish to be
limited either to the particular form of arresting devices applied to the vibrating har
or to the particular manner of locking the keys to said bar, it being sufficient for the
purposes of the invention that there he a movable bar common to and moved by each
of a number of keys, each of which keys becomes locked to said bar when operated,
and an arrester which engages the bar and prevents it being reset until the operated
key has been actuated to its full extent.
The combination of the arresting devices with the movable bar extending across the
keys forms a novel and valuable feature of my invention independently of the locking
of the keys, to said bar, and may be advantageously employed in machines where the
keys are not arrange to be locked to the bar-an instance which will be herein-
after pointed out in connection with the description of other features of my
invention.
The next feature of my 'nvention consists in combining with a movable bar common
to and moved by each of a number of keys and an arrester for such bar a locking-bar
actuated by said movable bar when any key is operated to lock the unoperated keys
from operation. Any usual or suitable locking bar may be used in this combination;
but I have devised one of novel form and operating in a novel manner, and which of
itself constitutes a novel feature of my invention aside from its combination with the
movable bar and arrester. This novel locking-bar (lettered W in the drawings and
shown in cross-section in Figure 2) extends across the rear of the machine slightly in
rear of and a little above the ends of the operating-keys D, and is pivoted at its ends
in the sides of the frame-work A or other suitable supports, so as to oscillate freely in
its bearings. It may be a flat bar of any suitable shape, in cross-section-such as
oval-or, as illustrated in the drawings, it may be substantially semi-cylindrical in
form, having its side next the ends of the keys cut away or flattened. Rigidly
secured to this bar at one end is an arm X. (in this instance by a collar Y and set-
screw w,) the forward end of which arm is connected to an extension of one of the
side arms J of the vibrating bar K by slot-and-pin connection at v. It results from
this construction and arrangement of the parts that when key is operated and the
bar K and arm J lifted the forward end of the arm X will be lifted with the arm J
and the locking-har W be rocked to the position shown in Figure 4, thereby moving
over the ends of the unoperated keys and locking them from operation. The bar W
is so shaped and arranged in such proximity to the ends of the keys that a slight
oscillation of it by the partial operation of any key is sufficient to cause it to move

page_text: over the ends of and lock the unoperated keys, and, inasmuch, as the bar K is
arrested and held at any point less than full operation by the arrester before described
and cannot be reset until actuated to its full extent, it results that after any key has
been substantially displaced from its normal position the bar W moves over the ends
of all the unoperated keys and beneath the end of the partially operated key, so that
the latter cannot he reset nor any of the other keys operated until the partially
operated key is further operated and its full value registered. The partially operated
key could not be reset before full operation for the further reason that it is locked to
the flange of the bar K by its hook m and must move with said bar; but this locking
of the keys to the bar K is independent of the operations of the bar W, and if the
keys were of the ordinary construction, provided with no hooks and free to move up
and down independently of the bar K, the result above described would be the same,
for the partially-operated key when released would fall until its rear end rested on
the upturned flat side of the bar W. but could go no farther. So far as this feature
of the invention is concerned, therefore, the bar W operates both as a key-locking and
key-arresting bar. The locking bar W may, however, he dispensed with and the
unoperated keys still be held from operation while any key is displaced from normal
position, for the upward extensions m' of the lugs which form the hooks m for
coupling the keys to the bar K have their forward faces curved in the are of a circle
of which the pivotal shaft J of the bar K is the center and the adjustment of the parts
is such that when the bar K is lifted the rear edge of its flange l, will move up the
forward curved faces of the lugs, in close proximity thereto, until it passes above their
upper ends, as shown by the dotted lines in Figures 1 and 2. It will thus be seen
that whenever the bar K is lifted by the operation of any key its flange 7 will lock all
the other keys and hold them locked till the operated key is again returned to normal
position. As the locking bar W and the upward extensions m' of the lugs serve
substantially the same purpose either the one or the other or both, may be employed,
as desired.
Another feature of my invention relates to novel means for preventing the operation
of the keys while the money-drawer is open. It may be employed either in connection
with or independently of the other features of the invention above described, although
in the present case I have shown all my improvements associated together and applied
to one machine. Loosely pivoted to one of the side arms Jof the bar K is a pendent
latch-arm Z, which is normally held in the position shown by the solid lines in
Figure 1 by a lateral projection w, Figure 5, on the upper end of the vertical arm a
of a bell crank A', pivoted to the frame work of the machine, as shown in Figure 1,
and whose other arm y is connected to the horizontal arm of a second bell-crank B¹
loosely pivoted to any suitable support in this instance hung on the bearing end of
the locking-bar Wand whose vertical pendent arm a extends down into the drawer-
compartment and carries an adjusting screw . When the drawer is closed, its
upper rear end hears against the forward end of the screw and holds the two bell-
cranks and the arm Z in the position shown by the solid lines in Figure 1. When a
key is operated and the drawer released and partially propelled from its compartment,
a coiled spring e pulls the two bell-cranks into the position shown by the dotted lines
in Figure 1, whereupon the arm Z falls against the side of a bracket lug d', projecting
inwardly from the frame-work A, and as the key and the arm J and bar K reach their
limit of motion the lower end of the arm Z moves over and rests upon the base of the
lug d and thereby latches the arm J and bar K in the position shown by the dotted
lines in Figure 1. In this position of the parts the locking bar W is in the position
shown in Figure 4. all the unoperated keys are locked by it, and the operated key
cannot be reset, both because it is locked to the bar K, as shown at 1 in Figure 1, and
because if it were not locked to the bar K the bar W would prevent its resuming its
normal position. When the drawer is again pushed in, its rear end strikes the
screw b, carried by the pendent arm a' of the bell-crank B, and throws the two bell-
cranks back to the position shown by the solid lines in Figure I, thereby causing the
lateral projection won the upper end of the arm x of the bell-crank A to knock the
lower end of the latch-arm Z off the bracket-lug d, whereupon all the parts are free

page_text: to resume their normal positions of rest (shown by the solid lines of Figure 1). For
the purpose of throwing out of operation this mechanism actuated by the opening and
closing of the drawer, so that the machine can, when desired, be operated with the
drawer either open or closed, I provide a lever (, pivoted to the frame-work at e¹,
and whose lower end extends over and rests against the lug when the lever is in
the position shown by the solid lines in Figure 1; but when its handle is pulled
forward until the spring-detent g' taken into the notch the lower end of the lever is
thrown backward, so that when the drawer is opened the projection we on the upper
end of the arm a of the bell-crank A' strikes against and is arrested by the lower end
of the lever (and holds the arm Z away from the lug d', so that said arm moves
freely up and down with the movements of the bar K, but its lower end cannot move
over and be caught upon the lug d'.
