Specification of Letters Patent.

Patented Feb. 3,1914.

To all whom it may concern Be it known that 1, CHARLES PALMER, a subject of the King of Great Britain and Ireland, residing at London, in the county of Middlesex, England, have invented certain new and useful Improvements in Cash- Registers, of which I declare the following to be a full, clear and exact description.

This invention relates to cash registers and has more particular relation to that class of cash registers provided with coin displaying mechanism for displaying the coins received as payment for purchases for which the machine is operated to record.

The primary object of the present invention is to provide a coin displaying mechanism of simple construction and convenient in form and location.

Another object of the invention is to so locate the displaying mechanism with relation to the indicating mechanism to enable one to see at a single glance the amount of the transaction as recorded in the machine and indicated by the indicating mechanism and the amount tendered by the customer as shown by the coins received which are exhibited by the coin displaying mechanism.

The invention has been shown as applied to a cash register of the type shown and described in Letters Patent of the United States issued to Thomas Carney on September 6, 1892 and numbered 4182,161 but it will readily be seen that the invention may equally as well be applied to any other form of cash registering machines.

With these and incidental objects in view the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and a pre ferred form of embodiment of which is hereinafter described with reference to the drawings which accompany and form part of the specification.

Of said drawings: Figure 1 is a sectional view of a machine of the type described in said United States Letters Patent with the present invention applied thereto. Fig. 2 is a top view of the invention, portions of the mechanism being omitted or broken away for the sake of clearness. Fig. 3 is a detail top plan view of a portion of the coin carrying belt and its driving pinion.

The operation of the machine to which the present improvements are applied is substantially the same as that shown and described in the above mentioned Letters Patent but for convenience may be briefly described as follows. The machine comprises a series of operating keys 20 pivotally mounted on a transverse shaft 21 hung between the side frames 22. Each key 20 is adapted when operated to raise and lower a key coupler mechanism 23 of well known form. The key coupler 28 is pivotally mounted in side frames 22 and extends above all the keys 20 to the rear of the shaft 21.

The coupler 23 is provided at one end with a pin 24 projecting into a transverse slot 25, formed in a vertically movable bar 26, so as to raise and lower said bar at each operation of a key 20 and consequent reciprocation of the key coupler 28. The bar 26 is guided in its movements by a stud 27 mounted on the main frame and projecting into a slot 28 formed in the lower end of said bar 26. At its upper end the bar 26 is formed with oppositely-facing racks 29 and 30 which alternately engage a pinion 31 mounted on a transverse shaft 82. Rack arm 29 is provided with a lug 33 which is arranged to ride on opposite sides of a flange 34:, mounted on the side frame of the machine, and thus hold the respective racks to mesh with pinion 31. This construction is old and well known in the art and it will readily be seen that an operation of a key 20 and the consequent reciprocation of key counler 23 will result in a rotation of shaft 32.

Mounted to rest on the rear end of each of the keys 20 are a series of standards 35, each of which carries at its upper end a flag 36 of well known form and adapted to indicate the amount registered at an operation of its appropriate key. At an operation of one of the keys 20 its appropriate indicator flag 36 will be raised and held in such position to expose to View, through a suitable opening in the cabinet (not shown), the numerals carried thereby.

The coin displaying mechanism of the present invention is arranged to extend across the machine just below the indicator sight opening. The coin displaying mechanism consists of a continuous belt 37 inclosed in a suitable inclosing casing 38 provided with an opening 39, to receive the coins tendered in payment of purchases, and a glass front 40 through which coins received for the last three purchases may be exhibited.

The belt 37 consists of a continuous flexible band 4E1 (see Fig. 3) provided on its outer surface with protecting strips 42 and having evenly distributed upon its surface strips 43 of greater thickness than strips e2, said strips T3 being provided evenly to divide the belt into sections of a. size sufficient to receive the coins tendered in a single trans action. Suitable operating mechanism hereinafter described, is provided to advance the belt the distance of one section at each operation of the machine to present an empty section at an opening 89 in the inclosing casing.

On its inner side the belt is provided with rack teeth 44 and at one end passes around an idle pinion or bearing 45 and at the other end passes around driving pinion 46. The pinion or bearing 45 is pivoted in plates 4-7 and 4:8 capable of adjustment to keep the belt taut.

The driving pinion 46 is mounted on the upper end of a shaft 49 the lower end of which is provided with a small pinion 50 meshing with a large .gear 51 pivoted at 52 to a platform 53 mounted on cross piece 5% of the main frame of the machine (see Figs. 1 and 2).

The gear 51 has mounted fast on its upper side a driving ratchet 55 adapted to be actuated by a pawl 56 mounted on a reciprocating lever 57 pivoted at 58 to the platform 53. The lever 57 receives its reciprocating movement from a link 59 pivoted at its forward end to lever 57 at 60 and bifurcated at its rear end to straddle shaft 82. An antifriction roller 61 mounted on link 59 plays in a cam groove 62 of a box cam 63 rigidly mounted on the rotation shaft 32. Upon a rotation of shaft 32 as before described the link 59 will be given a longitudinal reciprocation to actuate lever 57 thus forming a one way acting driving connection for the display belt through the medium of the intervening mechanism above described, viz., lever 57, pawl 56, ratchet. 55, gear 50, shaft 49 and driving pinion 46. A pawl 64 may be provided in constant en gagement with the ratchet 55 to act as a stop to prevent backward rotation of said ratchet.

At its outer end the lever 57 is provided with a shoulder 65 adapted, at the reciprocation of said lever to strike one end of a pivoted lever 66 to cause the other end of said lever to engage ratchet 55 to destroy its momentum and thus prevent an overthrow of the same and a consequent excessive feed of the display belt.

When the belt has been advanced an extent sutlicient to cause the inserted coins to reach a point over the pinion 46 they will drop from the belt into the hopper 67 at the upper end of a chute (3S and pass down through said chute into a receptacle 69 located in the base of the machine.

The general operation of the machine is as follows: lVhen a purchase is made and coins are tendered in payment thereof the coins thus tendered are inserted in the displayer through the receiving opening and are received in the section of the display belt which stands just below the receiving opening. At an operation of amount keys representing the amount of purchase the dis play belt is advanced through the medium of the mechanism above described to an extent suflicient to cause the coin containing section to move away from the receiving opening and the next empty section to the right to assume a position adjacent the receiving opening. The coins received are thus displayed through the glass cover of the displayer casing and as said displayer is located just below the sight opening through which the indicators representing the amount of purchase, may be viewed, it serves as a. check on the operator. In case of any dispute as to correctness of the amount of change, the amount tendered may plainly be seen by both customer and proprietor or clerk, as well as the amount of purchase as represented by the indicators displayed. By watching the displayer the customer may note whether or no the operator places the full amount tendered into the machine. As the coin passes down into a locked receptacle in the base of the machine, stealing of any money by the operator is thus prevented.

Vhile the form of mechanism herein shown and described is admirably adapted to fulfil the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein disclosed for it is susceptible of embodiment in various forms all coming within the scope of the claims which follow.
