THOMAS WARBURTON KELLET, of 16, Old Hall Street, Liverpool, in the County
of Lancaster, Printer and Stationer. "IMPROVEMENTS IN AND APPERTAINING TO
MACHINES FOR CHECKING AND FOR RECORDING THE AMOUNTS OF MONEY OR
OTHER QUANTITIES RECEIVED, PAID, OR TO BE RECORDED."
This Invention is designed, 1st, to give extra security to employers in the collec-
tion of accounts. By its use a receipt printed with the amount, date, and name of
the firm is obtained at the same time that a duplicate impression is made on a
running tape, which remains in the machine for future examination.
In the operation of setting the machine to any given amount of cash, that amount
is added to the amount previously on the index of the register wheels.
The mechanism of the machine consists of two sets of wheels, which we will call.
the stamping and the register wheels, driven by an intermediate pinion. This pinion
has a lateral motion on the winding shaft, and is acted upon by an adjustable slide
so as to gear into any wheel at the option of the user.
The periphery of the stamping wheels from which the impression is taken consists
of 12 teeth and 12 corresponding interstices. In the recording register the pence
wheel has 12 teeth, and is fitted on an eccentric centre; the other wheels of
recording register have 10 teeth each, and a ratchet wheel on the side, and revolve
on fixed boss centres.
The motion is conveyed from the pence wheel to the first wheel of the shillings
by a hook pawl, which rides upon the edges of a cam, shield, or washer placed
between the wheels, and in which there is a suitable indentation to allow the hook
pawl to come into action when required to move the first shilling wheel one tooth.
The first shilling wheel acts on the second shilling wheel when necessary. There
are ten teeth on the second shilling wheel, and also on the ratchet of the same, and
there are five indentations on the cam shield between the second shilling wheel and
the first pound wheel for the hook pawl to fall in, consequently this pound wheel
is moved five times for each revolution of the previous wheel; all other wheels are

pawls are so arranged that each ratchet will pass under the pawl of the wheel below
them in the series without acting on it, the said wheel being held in place by a
follower on the bracket attached to the adjustable slide. This enables the "register
to be broken at any point, so that the wheel will add any single number on any
wheel separately and give a correct total on the register.
"
The figures on the register wheels may be cut on the face of the teeth or in the
interstices as required.
On the printing wheels the printing figures are cut in reverse, on the face of the
teeth in relief, and are engraved or otherwise delineated in the interstices so that
they can be read easily. The figures on the interstices shew through a protected
slit in the case.
"
The stamping wheels are on a moveable shaft, which has what may be termed
fingers" or "drivers," which when the shaft returns return the whole of the wheels
to zero, this return being caused by a spring acting on the shaft. The wheels are
prevented going beyond zero by stops.
A ribbon passes immediately over the stamping wheels and moves a given
distance for each impression. Laterally over this passes a carbonized ribbon, and
over this is inserted the paper upon which the receipt is given; the pad acts directly
over the latter so that the impressions on the receipt and the duplicate ribbon are
identical.
This register can of course be adopted to any currency or system of addition, and
can be elaborated so as to print with ink if desired.
This machine is constructed to be carried in the pocket but may be made of large
size.
The mode of using is as follows:-
1st. Bring the slide (to which the before-mentioned sliding bracket is attached)
over to the extreme right hand, and wind up by means of a projecting stud or.
moveable key in a given direction (the person holding the key has alone access
to the register), the wheels at this time being held in position by a stop. On
moving the slide opposite the pence wheel and turning the key in the reverse
direction any desired figure from 0 to 11 can be exhibited at the slit. This figure
will be the one that on striking the machine, as hereafter described, will be stamped
on the receipt given and on the tape register; the same number will also be added
on the register wheel. The other wheels are set and actuated in a similar manner.
2. The impression on the receipt cannot be obtained until the slide is placed on
the opposite end to the winding action. The action of stamping returns the figures
shown in the slit to zero, so that a second impression cannot be got (except cyphers)
without resetting the machine.
3. To stamp the impressions insert the receipt form in the slit and press the end
of the machine.
