I, JAMES GRIEVE LORRAIN, M.I.E.E., M.I.Mech. E., of Norfolk House, Victoria
Embankment, London, W.C., in the County of Middlesex, Chartered Patent
Agent, do hereby declare the nature of this invention (as communicated to me
from abroad) to be as follows:-
This invention relates to improvements in cash registers by means of which
certain advantages are obtained.
In it the indications on the dials and the amount of movement of the integrat-
ing mechanism depends upon the amount of movement transmitted from the keys,
these keys being so constructed that the amount of movement of the transmitting
mechanism depends upon the key struck. Each key is capable of moving the
transmitting mechanism a definite amount and to this end the rods of the keys
are slotted to a definite extent vertically so that the slotted part straddles cross
pins arranged on the bottom rail or bar of the frame. On pressing a key move-
ment is transmitted to the transmitting spindle by means of a pin projecting
from the key rod which presses upon a longitudinal rod connected by links.or
levers with the transmitting spindle in such manner that the said movement
causes a partial rotation of the transmitting spindle, the amount of such partial
rotation being proportional to the downward movement of the key. At the
other end of the transmitting spindle is fixed an arc-shaped ratchet against which
pawls are pressed by springs. To the said ratchet is linked a lever, the other end
of which is connected to a toothed segment pivotted in the frame so that the
said segment may be partially rotated with each movement as aforesaid. These
segments gear with pinons keyed to the axles of the dials. The angular move-
ment of the transmitting spindle thus produces angular movement of its corre-
sponding dial the pawls aforesaid fixing the mechanism in each new position
taken up. The release of the said pawls is effected by means of a rod or frame
tilted or angularly moved by a slide and or wedge so as to press upon the said
pawls. At the back of the transmitting spindle counting or integrating gear is
attached in such manner as to sum up the angular movements of the trans-
mitting spindles and so indicate on a dial or other registering device the sum
total contained in the till of the machine.

furt-on-Main, Germany.
I, JAMES GRIEVE LORRAIN, M.I.E.E., M.I.Mech.E., of Norfolk House, Norfolk
Street, London, W.C., in the County of Middlesex, Chartered Patent
Agent, do hereby declare the nature of this invention (as communicated to me
from abroad) 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 by means of which
certain advantages are obtained.
In the invention the indications on the dials and the amount of movement of
the integrating mechanism depend upon the amount of movement transmitted
from the keys, these keys being so constructed that the amount of movement of
the transmitting mechanism depends upon the key struck. Each key is capable
of moving the transmitting mechanism a definite amount and to this end the
rods of the keys are slotted to a definite extent vertically so that the slotted part
straddles cross pins arranged on the bottom rail or bar of the frame. On pressing
a key movement is transmitted to the transmitting spindle by means of a pin
projecting from the key rod which presses upon a longitudinal rod connected by
links or levers with the transmitting spindle in such manner that the said move-
ment causes a partial rotation of the transmitting spindle, the amount of such
partial rotation being proportional to the downward movement of the key. At
the end of the transmitting spindle is fixed an are shaped ratchet against which
pawls are pressed by springs. To the said ratchet is linked a lever, the other end
of which is connected to a toothed segment pivotted in the frame so that the
said segment may be partially rotated with each movement as aforesaid. These
segments gear with pinions keyed to the axles of the dials. The angular move-
ment of the transmitting spindle thus produces angular movement of its corre-
sponding dial the pawls aforesaid fixing the mechanism in each new position
taken up. The release of the said pawls is effected by means of a rod or frame
tilted or angularly moved by a slide and or wedge so as to press upon the said
pawls. At the other end of the transmitting spindle counting or integrating
gear is attached in such manner as to sum up the angular movements of the
transmitting spindles and so indicate on a dial or other registering device the
sum total contained in the till of the machine.
In order that the invention may be more readily understood drawings are
appended hereto illustrating the same.
In these drawings,
Figure I is a plan of what may be termed a quadruplex machine, that is to
say a machine having four banks of keys and four dials.
Figure II is an external elevation of one of the banks of keys.
Figure III is a plan of a part of the bottom rail or pin bar.
Figure IV is a part elevation part section showing how the transmitting
spindle is actuated by the keys.
Figure is a rear elevation of one half of the machine showing the mechanism
for operating two of the dials and also showing part of the releasing mechanism.
Figure VI is a side elevation of the releasing mechanism.
In these drawings similar numerals of reference indicate similar parts.

page_text: Referring now to the several figures, 1 to 9 are the several keys which as will
be hereinafter described bring that part of the dial corresponding with the key
struck to its indicating position, the said dial being marked with numerals corre-
sponding with the keys. Each key rod has a slot 10 of definite length and by
means of these slots the key rods straddle the cross pins 11 which stretch across
orifices 12 in the bottom rail or pin bar 13. Thus each of the keys can be de-
pressed until the top of the slot 10 comes in contact with the cross pin 1.1.
Upon each key rod is a clip 14 from which projects a pin 15 which presses upon
the longitudinal rod 16 connected by a lever or rod 17 with the transmitting
spindle 18 so that when the key is depressed (see Figure IV) it will travel down-
wards until the end of the slot reaches the cross pin 11. In so doing the trans-
mitting spindle 18 will be moved angularly round in the direction of the arrow
through an angular distance determined by the length of the slot in the key rod.
Thus if key be depressed the transmitting spindle will only move through a
small angle on account of the shortness of the slot in the rod of said key 1. On
the other hand if key 9 be depressed the greater length of its slot will cause the
transmitting spindle to be moved through a greater angle. Similarly inter-
mediate keys will cause movement of the transmitting spindle through angles
intermediate between those caused by key 1 and those caused by key 9.
At the end of the transmitting spindle is fixed an are shaped ratchet 19 (see
Figure V) against which pawl 20 is pressed by spring 21. To the said ratchet
is linked a lever 22 the other end of which is connected to the toothed segment 23
pivotted in the frame at 24. This segment gears with a pinion 25 keyed to the
axle 26 of the dial 27. This dial is moved through an angular distance deter-
mined by the amount of angular movement of the transmitting spindle. Thus
(Figure V being still regarded) on movement of the transmitting spindle 18
in the direction of the arrow, the arc shaped ratchet 19, (which has a number of
teeth equal to the number of keys) will be moved as shown by its arrow, lever 22
will be pulled down, toothed segment 23 will be moved in the direction shown
by its arrow and pinion 25, arbor 26 and dial will be moved contra-clockwise.
But as the angular movement of transmitting spindle 18 has been shown to
depend upon the key depressed so the angular movement of the dial 27 will also
depend upon the key pressed and therefore that part of the dial on which is
marked the number corresponding with the key will be brought to its indicating
position, or opposite the window of the machine.
Immediately after the movement just described has taken place, that is to say
after the key has been depressed, spring 21 will force pawl 20 into that notch of
the arc shaped ratchet 19 which corresponds with the key struck and which is
opposite the gripping end of the pawl and the parts will be retained by said pawl
in the position taken up so that the number upon the dial remains displayed as
aforesaid.
Thus it will be seen that the indication given depends upon the key struck and
I shall now proceed to describe how the parts may be released from the position
taken up after each operation of the machine.
The releasing mechanism is best seen in Figures VI, I, and V. Each pawl 20
has an extension piece 28, the extension piece of the one overlapping that of the
other as will be seen in Figure V so that depression of the upper one 28* will
necessarily also depress the lower one 28. This depression, which as will be seen
releases the pawl from the arc shaped ratchet 19, is brought about by depression
of the extremity 29 of the tilting frame 30. This frame is tilted or angularly
moved upon its centres 31 by the movement of the slide 32 in the direction of
the arrow when it will be seen that the inclined wedge 33 comes under the inner
part of the frame and tilts it so as to depress the point 29. Such depression depresses
the extension piece 28 and removes the point of the pawl 20 from the are shaped
ratchet when the parts are brought back to their normal position, namely the
position occupied in the figures, by a spring or springs attached to any convenient

page_text: parts as for example is shown by spring 38 in Figure IV. The slide is moved
by the rod 34.
35 is a box containing the usual integrating mechanism which is actuated by
the movement of the transmitting spindle 18 in such manner as to sum up the
angular movements of the transmitting spindles and so indicate on an integrat-
ing dial the sum total of the angular movements representing the total sum
passed to the till of the machine in the usual way.
36 is a ticket box such as may be used in connection with this as with other
cash registers but which forms no part of the present invention.
37 (see Figure IV) is a retaining pin which it is found convenient to employ to
prevent further movement of the parts when the key has been depressed to its
full extent. When in such depressed position the rod 16 occupies a position
between pins 15 and 37 as will be readily understood.
It is to be understood that the invention is not limited to the precise details of
construction herein set forth as it is obvious that any skilled mechanic may vary
such details to an indefinite extent without departing from the spirit of the
invention.
Having now particularly described and ascertained the nature of this inven-
tion (as communicated to me from abroad) and in what manner the same is to be
performed, I declare that what is claimed is:-
1. In a cash register determining the amount of movement of the indicating
and or integrating mechanism by the amount of movement of the key struck
