Abstract: 14,062. Guess, E. June 24. Receipts, checking and recording. - Cash is inserted into appropriate openings in the device,and then passed on to three tills for copper, silver, and gold, while the amount is indicated, and also added to the amount already registered, by moving corresponding indicators on a switchboard. The dials may be situated at any distance from the switchboard, and any number of switchboards may register the total receipts at one place. The switchboard consists of a plate a carried by a casing and having four sets of horizontally sliding knobs b, b<1>, b<2>, b<3>, Figs. 3 and 4, marked and coloured respectively to represent a certain number of farthings, pence, shillings, or pounds. Each knob is carried by a plate c, Fig. 7, sliding in guides c<1> fixed on the back of the plate a. Each plate c has a cam plate c' carrying a rack l with which engages a pawl l<1> pivoted to the plate a. The cams, when the indicators are moved, engage the levers d, d, d', d<3>, Figs. 3 and 4, which are for farthings, pence, shillings, and pounds respectively, and which are moved a greater or less distance according to the indicator knub which is operated. The levers are pivoted at d<4>, d<5>, d<6>, d<7> respectively, are returned to their positions by springs g, g<1>, g<2>, g<3>, governed by dash-pots h, h<1>, h<2>, h<3>, and carry contacts e, e<1>, e<2>, e<3> which travel over metallic teeth f, f<2>, f<3>, f<4> carried by insulated segmental blocks f<1>, f<5>, f<6>, f<7>. Each contact consists of a pivoted metal piece controlled by a spring e<6>, and faced with an insulating-material, so that contact is only made on the return movement. The number of teeth on each block corresponds to the number of units of farthings, pence, shillings, and pounds for which the device is intended. The levers are moved outwards to a greater or less extent according to the shape of the operating-cam, and the distance thereof from the pivot of the lever. Each lever has a contact-cheek e<8> which rubs on an insulated block f<1>, f<5>, f<6>, f<7> and completes an electric circuit and rings a bell i or other signal. It also sends a current through one of three incandescent electric lamps carried on the casing. The lamps are of different colours, viz., white for copper, red for silver, and yellow for gold. A trigger k, Fig. 7, is pivoted below each plate so as to engage with the plate c<2> when the levers are in their normal positions, but, when a lever is raised, the trigger releases the plate, while a pawl l<1>, gearing with the rack l, allows the plate to pass to the right or left. The recording-device consists of a casing divided by a vertical partition into two parts, in which are the dials and the mechanism respectively. There are five dials for representing respectively farthings, pence, shillings, pounds, and multiples. The dials have hands or pointers with knobs for turning back to zero, the knobs being covered by a pivoted locking-frame. The hands are moved forwards by an electrical step-bystep movement. Fig. 11 shows the operating- mechanism for the shillings' dial. The axle q carrying the hand carries also a ratchet-wheel r having twenty teeth, representing the number of shillings in a pound. A rod s forms a continuation of the core s<1> of a solenoid s<2>, and to it is pivoted a weighted or spring pawl r<2>, which is tripped by a fixed stop r<4> when the circuit is completed, and thereby engages the ratchet-wheel. A spring r<5> returns the rod s, and a spring r<6> prevents backward rotation of the ratchet-wheel. The axle has a single tooth q<1> to complete the circuit once every revolution of the ratchet-wheel actuating the pound hand. For this purpose, the tooth may engage a pivoted lever q' having contacts q<3>, q<4> dipping into mercury cups q<5>, q<6> included in the circuit of the next solenoid. A spring or weight q<7> raises the contacts again. The electric circuits are shown in Fig. 15. The movable contacts e, e', e', e' and sliding contacts e<8>, Figs. 3 and 4, are in electrical communication with one another and with the batteries z, z<1>, and the teeth f, f<2>, f<3>, f<4> are connected to the solenoids of the corresponding indicating-devices t, t<1>, t<2>, t<3>. The other terminals of the solenoids are connected to batteries z<1>, z<2>. The contacts f are connected to the indicating- lamps j, j<1>, j<3>, which are also connected with the battery z and bell i. The mercury cups q<5> are connected to the solenoids, to the other poles of which the other mercury cups q<6> are connected. The terminals on the switchboard are represented at x, and are placed on the top of the casing and enclosed in a removable casing a<2>, Figs. 3 and 4, while those of the recording-dials are shown at y and are contained in a separate compartment of the dial casing. The cash is placed in a slot u<6>, Fig. 16, and enters a semicircular casing u', which is the only part projecting above the counter, falling into one of four radial triangular receptacles forming a wheel w. The receptacles are then rotated one quadrant by pulling forwards a lever w<7>, controlled by a spring w<12>. A bevel pinion w<5> turns with the lever w<7> and operates a bevel pinion w' loose on the spindle of the wheel. A spring pawl w<3> on the pinion w<4> engages with a ratchetwheel w<2> fixed on the spindle, and thereby turns the spindle upon which the wheel is mounted. The coin is then visible through the transparent panel in the right hand compartment, and on the next movement is discharged into the locked-up drawer u<1>. To prevent the receptacles w from being tampered with, they are locked in position by the end of a double-armed spring lever w<8>, which is withdrawn before the receptacles are to be turned by projections on the ends of the levers w<7>, w<8> engaging at the commencement of the outward movement of the former. In addition, a bell v<3> is rung by means of the hammer v<2>, the doublearmed spring-controlled lever v, v<1>, and the ratchetwheel w<2>. The casing u' is secured to the casing u by spring arms u' engaging with studs u<5>. These can be disengaged only when the drawer is opened. The Provisional Specification states that either or both registering and adding dials may be used with the switchboard.
