This invention in general relates to coin op erated devices and more particularly to a new device for recording pluralities of coins of differ:-

entpredetermined denominations;

Coin mechanisms previous to thi invention usually were dependent upon the action of gravity upon thecoins for registration or the :deterpalpation of their values. Such devices frequently were rendered inoperative by the insertion of deformed coins or debris. The electrical or mechanical means responsive to coin in gravity. devices are required to be of exceedingly sensitive construction, particularly when adapted for use with relatively light-weight coins. Motor driven coin device usually were dependent upon an element for carrying the coins in pockets or to displace a plurality of obstructions in order to register values. This .type device is also subject to frequent failure when encountering deformed coins. or debris which would jam the pockets-or disturb'the natural functionof theprojections.

In the present invention all of the above difficulties are completely overcome in the novel means employed whereby the coins. of different denominations are. conducted to respective conduits and are forced by motor driven means to travel through separate predetermined paths in .a naturalrolling motion to displace registering elements proportional to the diameters of the different coins. Deposit of deformed coins or other debris, which is passed through an appropriate entrance aperture, will readily pass through the device without interruptin or injuringt-he mechanism. p

A principal object of. the invention is the, provision ofamotor driven coin registering device wherein coins of each denomination are urged through predetermined pathways to displace a registering element predetermined distances in accordancewith the diameters of the respectivecoins.

A further object of the invention is the provision of a motor driven rotary means whereby a single coin responsive member is displaced a predetereach having different contours, whereby a motor driven member responsive to the coins movements in the said passageways will be displaced predeter mined distances dependent upon the diameters of the coins deposited therein.

These and other objects and advantages will appear in one embodiment ofthe invention, in

which: a

- Fig. 1- is a top plan view of the device.

. Fig. 2 is a side elevation of the device. showing a section taken through section lines 2.2, Fig. 1.

Fig. 3 is aside elevation same as Fig. 2 with v Fig-.5 is a diagrammatic elevation showing the mechanism of Fig. 4 in changed position.

Referring to'Figs. 1 and 2, aplate l serves as a frame for retaining the various elements to be described. An electric motor 2 is pivotally suspended on a fixed shaft 3 secured at one end to the frame I. The'motor drive shaft lextends through a clearance hole 5 in'the'plate l and serves as a frictional drive roller. It is apparent that the motor and its drive-shaft 3 are capable of lateral movement with respect to the plate i by virtue of the pivotal mounting 3; [A frictional drive wheel 6, having a resilient rim and an integralpinion'l-afi'ixed concentrically thereto, is carried on anaxle 8 secured at one end to the plate I. A pressure roller 9 is rotatably secured to an axle i0 affixed to an arm ll; The-arm is pivotally mounted-to the plate I bystud |-2'.- A

spring l3 secured to'thearm I! at one end-and suspended by a fixed bracket 14 at its opposite end,- is provided to urge the-roller 9 in contact with the drive shaft-4. Thus the drive shaft 4 is urged by rollerB into frictional, contact with the drive wheel 6. The motor bearings supporting the shaft 4 are relieved of large frictional stresses and at the same time frictional driving con-tact between the drive shaft 4 and the rim of the drive wheel 6 is constantly maintained. A rocker menu-- ber i5 is freely suspended on axle 8 and serves a a hanger for the axle of the coin roller l6, which roller carries a resilient tire for engagement with the rims of coins. A- ear l1 integral with the roller i6 is meshed with and driven by pinion]. Thusit can be seen from Fig. 2 that when the drive shaft 4 is rotated in a clockwise direction, the roller Iii will rotate in the same direction. An arm l8 integral with hanger i5 is adapted to operate lever 19 through the medium of a pivotally mounted link 23. Lever i9 is pivot-p ally mounted to the frame I by stud 20 and urged in one direction by spring 2I attached to the lever Y at 22 and secured at its opposite end to bracket I I.

Thus the hanger I 5 and the roller I6 are normally held in the position shown Fig. 2 by a stop provided by bracket I4 in the path of the arm I8.

A ratchet-wheel 24 is aflixed to the plate I by screw 25 located concentric with the stud 29. This wheel is adapted to turn freelyon its hub and in this particular embodiment is made from insulating material. A pawl 26 is loosely mounted to one end of lever I9 and urged toward the wheel by a spring 21. A pair of contact springs 28 and 29 are secured to the frame I by a bracket 30 and conventional insulation means. The working end of spring 29 is formed to provide detent engagement with the teeth of the wheel 24. Thus it can be seen that when the lever I9 is oscillated through a predetermined distance, the wheel 24 will b moved by the pawl 26 in a direction shown by arrow, Fig. 2. This movement will momentarily close the contacts of the contact springs 28 and 29 a given number of times dependent upon the displacement; of lever I9. In this particular embodiment of the invention, runways are provided for coins of three different diameters. The runway assembly comprises three tracks 3|, 32, and 33, having different working face contours to carry three coins; namely United States nickel, dime, and. quarter. The tracks'are held in spaced relation by separators 34, 35, 36, and 31. The tracks and separators are secured to the plate I by screws 38 and spacers 39. The coins of different diameters are fed by suitable conduits, not shown, into the respectivetracks 3I, 32, and 33 usually after they have passed through a coin-sorting and slug-eliminating device, also not shown.

Referring to Fig. 3 and assuming that a United States nickel is deposited in the outer track 33 and assuming that the electric motor is in operation and the coin wheel is turning in the direction shown by arrow, the opposite edges of the coin will wedg between the surface of the track 33 and the adjacent periphery of the roller I6 and be moved downwardly by the roller which will simultaneously move away from the track. This movement will displace the lever I9 to momentarily close the contacts 28 and '29 one time as previously described. Thence the coin will pass from the bottom of the device in a path shown by arrow. The action of the spring 2| will then return the lever I9, the link 23, and the roller I6' be closed a greater number of predetermined times.

Fig. 5 illustrates the pass-age of a coin of largest diameter by virtue of the track 3I having the longest face. This embodiment was adapted to move the lever I9 shown Fig. 3 andthe ratchet wheel 24 an angular distance sufficient to close the contacts 28 and 29 five times. Referring to Fig. 2., it is apparent that since the hanger I5' is pivoted about the axis of axle 8. the cradle carrying roller I6 will likewise follow an are centered through the axis of axle 8. therefore, the working faces of the tracks 3|. 32 and 33 are arbitrary with reference to the center of axle 8 a d y may be proportioned to cause a coin to displace the roller an increasing distance dependent upon the length of the working surface of the arbitrarily positioned track. Thus it has been shown that successive coins of difierent denominations deposited in the proper runways will operate contacts 28 and 29 in accordance with their diameters to initiate a suitable electrical device to register the predetermined value of the coins inserted. It is obvious that the oscillating motion transmitted to the lever I9 by coins of various diameters may be employed to operate mechanical devicesrather than the electrical contacts shown. It is also'obvious that the range of movement of the lever I9 may be altered by changing the tracks to provide various ranges of movement of the lever I9 or various commutations bythe contacts. It is also apparent, and it is intended to be covered in the scope of the appended claims, that a modification of the device in which alternate construction provides the same relative motion between the wheel 6 and the runways by maintaining the rotar roller IS in a fixed position and pivotally mounting the runways about their upper screw 38 and transmitting the resultant runway movement to lever I9.
