6 Claims.

This invention relates to a check controlled 'mechanism for a check controlled device and a special check for use therewith.

An object of the invention is to provide a check of such construction and production cost that it cannot be counterfeited profitably together with a machine adaptedY to be operated thereby and not susceptible to operation by simpler checks.

More specically stated, an object is to providea check having relatively rotatable parts and means associated therewith for causing rotation of one of said parts in one direction to impart opposite rotation of the. other of said parts, the check receiving chute and associated parts being so constructed as to be operated by such check but not susceptible to operation of checks not providing suchreversal of rotation.

Other and more limited objects will be in part apparent and in part pointed outhereinafter in .connection with the accompanying drawing wherein Fig. 1 is a fragmentary section taken through a coin receiving chute of a device embodying the invention and showing the v:special check inv the position it assumestherein when dropped into the check receiving chute and before the operating handle has been actuated; Fig. 2 is a transverse section taken centrally through' the check seen in Fig. 1; Fig. 3 is an enlarged detail section corresponding' to the line 3-'3 of Fig. 2; Fig. 4 is a plan View of the check' receiving chute showing the shape of check re-r ceivingA opening adapted for preventing insertion of the check of Figs. 1 and 2 in a ymanner which will result in improper operation of thel r device; and Figs. 5 and 6v are detail views of a modified form of check which may' be inserted with either face presented toward the operating handle, Fig. 5 being a central section and Fig. 6"

being a fragmentary elevation thereof.

In the drawing I have illustrated only aV frag# ment of the coin controlled mechanism, it being understood that the parts illustrated'may form any integral part of a check controlled device of any kind such as a vending machine, phonograph, game or the like. i

The numeral I 0 indicates a check receiving chute having an opening' II in one edge thereof. Adjacent the opening II is a bracket I2 upon which is" pivoted an arm I3 as indicated at I4. The arm I3 is provided at one end with an opening' I 5 which receives av reduced portion I6 of a check stop element I 'I. The element I1 has its inner end adapted to engage the check and is limited as to its extension through the opening II into the coin chute by a xed collar I8. The

arm I 3 is provided with a collar I 9 between which and the collar I 8 is positioned a spring 20 adapted to yieldably urge the element Il toward the position shown in Fig. 1. A spring 2I is provided for toward the position` 6 normally urging the arm I3 l shown in Fig 1. Attached to the end of the arm i3 is a link I4 which, responsive to motion of the arm f3, may operate-acoin controlled de vice. This operation may take the form of closing a Switch 0l" leleaSillga detent ormay actu- 10 ally operate the machine as, for example, by

actuating an article ejector.

At the upper end of the coin chute I Il'v is a coin receiving opening 22' formed in a plate 2'3 p' andof a form to receive the checkshown in 15' Figs. 1 and 2 only when the proper face thereof ispresented toward the actuating handle. One face of the coin chute at a point `opposite the check as it rests on the element Il is a backing 24A of' friction material against which the check 2D v may be urged. Opposite theelement 24 the chute is formed with a boss 25 within which is Journaled one portion of an actuating handle 26. The boss 25 is formed with a removable element 2 the lower end of which denes with the in- 425k f teriorsof the boss 2.5 a cam groove 26. Working in the cam groove 28 is a pinv 29 carried by the handle 26. The inner end of the handle 26 is formed'with socketsSll carrying spring pawls.

3 I` which are adapted to cooperate with-` a ratchet -30 extension 32 on a disk 33 rotatable on the inner face of the4 coinchute and being providedV` with a friction facing 34. yThe operating handle 26 is rotated against the action of the spring 35 to operatethe device and is `returned by suchspring to' normal position after operation.

Thecheck shown in Figs. l andy 2 consists of inner andy outer relatively' rotatable elements 36 and 3l' together with -means operated by the handle 26 and friction bearing rotation of the inner element 36 in a counterclockwise direction to impart clockwise rotation to the outer elem'ent'I-Lv Such means includes a mounting element 38', which is adapted to be held againstrotation by frictional engagement. .'45

with the backing element 24 and within which the inner element 36 is pivoted. Anti-friction means 39" may be inserted between the elements 36 `and 38'. The element 3B has journaled therein aplural'ity of pinions 40. While these pinionsvv g@ rotate about stationary'axes inthe operation of n the device, they will be referred to as planetary gears in view of their relationship to the other elements. These pinions mesh with the externally toothed rotatable gear l36 and with the 55 24 for causing internally toothed gear 31. The gear 31 has a flange 4I overlying a portion of the element 38 as well as an internally extending flange 42 overlying the pinions 40 and preventing escape thereof. The flanges 4l may be swung over to the position indicated after the parts have been assembled. The outer element 31 is provided with peripheral notches 43 adapted to receive the element l1.

In operation the check is dropped into the check receiving chute through the opening 22 thereby assuring proper. orientation vand under the action of gravity assumes the position shown in Fig. 1. The operating handle 26 is now operated in a counterclockwise direction against the action of the spring 35. This will result in rotation of the element 33 and at the same time will produce an axial motion thereof causing a gripping of the check between the elements 34 and 24. The backing element 24 will hold the element 38 against rotation while the continued rotation of the operating handle 26 will impart counterclockwise rotation to the element 36. This will result in rotation of the pinions 40 and consequent rotation of the element 31 in a clockwise direction. Such clockwise rotation of the element 31 will move the element I1 upwardly to the limit of the opening Il. When the handle is released it rotates in a clockwise direction, the elements 33 and 34 remaining stationary for a time, the ratchet 3l, 32 allowing rotation of the handle 26 clockwise without rotation of the elements 33 and 34 until the cam follower pin 29 has reached the point to release the friction grip on the check between the elements 24 and 34 whereupon the check will be kicked downwardly by the element i1 under the action of the spring 29, the check controlled device having been operated through the medium of the link I4. The parts now being restored to normal position the device is ready for a subsequent operation. It is to be understood that any conventional means may be provided for removal of slugs introduced into the machine in an attempt to operate the same.

In Figs. 5 and 6 I have shown a modified form of check which requires no special means such as a plate 23 for insuring proper orientation. This check consists of annular plates 44 having a plurality of pinions 45 journaled therebetween, such plates being held in proper spaced relation by shouldered rivets 46. The annular plates 44 are of such width as to overlap the adjacent edges of a central externally toothed gear 41 and an outer internally toothed gear 48 provided with peripheral notches 49 like those of the previously described check. When this check is to be used in connection with the device shown in Figs. 1 and 2, the elements 33 and34 engage the central gear 41 through the opening in whichever of the annular plates 44 is presented, the other annular plate being engaged against the frictional backing element 24 to hold the pinions 45 in fixed position so that rotation of the gear 41 in one direction will result in 4opposite rotation of the gear 48 whereby the machine will be operated. While I have shown and described the preferred embodiments of my invention I wish it understood that the same may be realized in varying structures and that I am limited only in accordance with the appended claims.

Having thus described my invention, what I claim is:

1. A check for operating a check-controlled device, comprising, in combination, an internally toothed gear, an externally toothed gear and planetary gearing interposed between and meshing with said two first mentioned gears.

2. A check for operating a check-controlled device, comprising, in combination, an internally toothed gear, an externally toothed gear and planetary gearing interposed between and meshing with said two first mentioned gears, said planetary gearing comprising a mounting element carrying one or more pinions and projecting axially beyond said two rst mentioned gears.

3. A check for operating a check-controlled device, comprising, in combination, a pair of annular elements, means for holding the same in special relation to each other, pinions journaled in said annular elements and positioned therebetween, an inner, externally toothed gear and an outer, internally toothed gear meshing with said pinions, said annular elements overlying at least one of said gears.

4. A check for operating a check-controlled device, comprising, in combination, a pair .of annular elements, means for holding the same in special relation to each other, pinions journaled in said annular elements and positioned therebetween, an inner, externally toothed gear and an outer, internally toothed gear meshing with said pinions, said annular elements overlying at least one of said gears and projecting axially beyond both thereof.

5.
