page_text: improvements in Cash Registers and Indicators.
I, HERBERT JOHN HADDAN of 67 Strand 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, 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 :-
This invention relates to improvements in cash registers and indicators designed
for the use of storekeepers and others as a means of accurately registering the
total cash receipts for any given period of time, as a day, for instance, and for
indicating to the customers that the amount paid has been registered, by disclosing
to their view such amount upon figured tablets.
The novelty of the invention will be herein set forth, and distinctly pointed out
in the claims.
In the accompanying drawings:
Fig. 1, is a sectional side elevation with portions of the framework broken away,
of a cash register and indicator embodying the present improvements.
Fig. 2 is a side elevation of the machine, with a portion of the removable cover
broken away to illustrate the locking mechanism.
Fig. 3 is an enlarged detail elevation, partly in section, of the bolt mechanism
for locking and releasing the drawer.
Fig. 4 is an enlarged side elevation of one of the operating keys and weighted
dog secured thereto.
Fig. 5 is an enlarged plan view of the drawer-locking plate.
The same letters of reference are used to indicate identical parts in all the
figures.
In the present invention I provide rearward extensions to the side arms of the
vibrating frame E, which extensions are formed into weights L, which may be
either integral with the side arms of the vibrating frame, or may be connected
thereto and made adjustable if desired, thus producing a counterbalanced vibrating
frame that will re-set itself and return the keys to its normal position after every

operation. In this manner the unequal strain on the vibrating frame occasioned
by inequality in, or improper location of, the springs, is entirely avoided.
The next feature of the invention consists in providing the key-dogs M, which
are pivoted to the keys O and work in slots in the lateral extensions a thereof,
with forwardly turned weighted ends b, in such manner that the dogs are held in
constant engagement with the teeth c of the registering disks, as seen by reference
to Figs 1 and 4. The same advantages are obtained here by the employment of
counterbalanced dogs, as in the case of the vibrating frame.
The next feature of the invention consists in securing a weight N to an inwardly
projecting arm or extension of the wing G, Fig. 1, in such manner that the weight
causes the re-setting of the wing and operates the bell-hammer O, thereby dis-
pensing with the spring formerly employed for this purpose.
The improvements above designated not only materially cheapen the construction
of the machine but they render its operation more certain and reliable, and there
is nothing about them to break or possibly get out of order, and this is very
important when it is considered that machines of this class are generally operated
by persons supposed to be hostile to their use, and who often subject them to the
most severe usage possible.
The next feature of the invention consists in the employment of a lock to be
secured to any convenient part of the case, and preferably located within the
same, but accessible by means of a key in the possession of the proprietor, and
with its bolt so arranged that by projecting it, it engages with some of the
operating parts of the machine in such manner as to lock the entire machine and
prevent its being operated or tampered with during such times as it is not desired
to be used in the ordinary course of business.
As an additional illustration of this feature of the invention reference is inade
to Fig. 2 where P represents the lock secured to the inner side of the removable
cover or lid d of the case A; e the keyhole of the lock, extending through the lid,
and the bolt, which, when projected, engages with the stop-lug g upon the
trip-rod R.
It will be readily seen from this construction, that by locking the trip-rod R
the vibrating frame is thereby locked and the keys held up and prevented from
being depressed.
While this is the preferable application of the lock, it is obvious that it might
be applied to any of the operating parts of the machine, excepting the keys
separately, with the same result, for all the parts of the machine operate and
co-operate simultaneously when any of the keys are depressed.
The remaining features of the invention relate to the drawer-locking and
releasing mechanism, and are illustrated particularly in Figs 1, 3 and 5, where S
is a lever or arm journalled in ears h, preferably forming part of a metal support T
secured to the upper wall of the drawer compartment, and which lever is held
up by a spring i in constant engagement with the front cross-piece of the vibrating
frame E. The rear end of this lever has pivoted to it a bolt U, which is confined
in a vertical aperture in an enlarged recessed projection j of the support T. The
lower end of the bolt is bevelled as shown, and the projection j, which extends
into the drawer compartment, is provided with a horizontal slot k opening towards
the front and having its mouth flared or bevelled, as shown at 11. Upon the
rear side of the drawer, which is suitably recessed, is secured the locking plate V,
provided with a transversely elongated opening m, and having its rear edge
bevelled off.
It will be seen from this construction that when the drawer is pushed in, the
plate V passes into the slot k, raises the bolt U which instantly thereafter drops
and engages with the walls of the opening m in the plate, as will be readily
understood.
W is any suitable projecting spring which is compressed when the drawer is
locked, and which, when the bolt is raised by the operation of any of the keys,
partially propels the drawer from its case.

page_text: To insure the more perfect working of the drawer, I provide rollers n, which are
recessed in each side of the drawer compartment in the bottom of the case, and
upon which the drawer rests and travels.
The advantages of the above construction of the drawer mechanism will be
apparent when it is understood that these machines are frequently required for use
on soda fountain counters, where there is more or less slop, which is apt to get into
the drawer compartment and cause the wood to swell and the drawer to bind.
I am enabled, by the means above referred to, to make the drawer sufficiently
small to counteract the effects of the swelling, and at the same time, by means of
the plate V and the flaring mouth of the slot k, to always insure the proper locking
of the drawer whenever it is pushed in.
Having now particularly described and ascertained the nature of said inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is :-
1. In a cash register and indicator, the combination with a series of keys of
fixed values, a series of tablets, and registering mechanism, said tablets and regis-
tering mechanism being operated at each stroke of any of the keys, of the
vibrating frame E, having its rear part weighted, substantially as described, whereby
said frame automatically re-sets itself and causes the return of the keys, as and
for the purpose specified.
2. The combination in a cash registering and indicating machine having a series
of registering disks provided with teeth, of keys C, arranged as described, and
provided with slotted extensions through which pass the upper ends of the dogs M
pivoted to the keys, and having forwardly pendent weighted extensions 6 for
causing the constant automatic engagement of the dogs with the teeth of the disk.
3. In a cash register or indicator, the combination with the tablet-supporting
wing G, tablet-rods F, and bell-hammer O, of the weight N secured to the sup-
porting wing, whereby the action of said wing in re-setting itself and sounding
the bell is rendered automatic, substantially as described.
4. In a cash register and indicator, substantially such as described, the combi-
nation with the case A, of a lock P applied thereto and adapted to engage with
one of the operating parts of the machine, whereby the machine may be locked to
prevent its operating, substantially as described.
5. The combination with the vibrating frame E, of the lever S baving pivoted
to its rear end the vertical bolt M confined in an opening in the head ; which is
provided with a slot k having a flaring mouth, and the money drawer or till K
provided with the locking plate V having the elongated opening m, the parts
constructed and arranged substantially in the manner and for the purpose specified.
