To all 'whom 'it may concern:

Be it known that I, CHARLES M. LINDE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Coin-Operated WVending-Machines, of which the following is av specification.

My invention relates to an improvement in the class of vending machines employing a rotatable measuring-cup' normally registering with the outlet in the base of a magazine and filled from the contents thereof consisting of the supply, in bulk, of the article (pea-- nuts, candies,and'the like) to be vended, the cup being normally locked in that position against rotation to effect em tying it of its contents for delivery thereof, ut ada ted to be unlocked to permit such rotation t ough the medium of an inserted coin of proper denomination.

The object of my invention is to improve, in matters of detailupon a certain vending machine in the class referred to, now on the market, to the end, more particularly, of protecting it against imfproper or -fraudulent operation, and that o more reliable.

In the accompanying drawings, Figure 1 is a view in front elevation of the complete machine; Fig. 2 is an enlargedI broken section on line 2, Fig. 1 Fig. 3 is a broken section on the rendering its operation irregular line 3, Fig. 2, viewed inthe direction of the arrow, and showing the parts of the operating mechanism in their normal Epolsition; Fig. LLis a similar view on line4,

2, regarded in the direction of the arrow, but showinglthe parts of the operating mechanism in t by a partial turn of the shaft and wherein the delivery-cup is in incomplete registration withthe discharge-opening leading to it from the bottom ofthe magazine; Fig. 5 is a section on the line 5, Fig.` 3, and Figs. 6 and 7 are perspective views, respectively, of the segrllliental head and lever coperating therewit The base 8 of the machine is a hollow body,

consisting, in practice, .of a malleable casting with a dish 9 near the bottom of its front side, -rinto kwhich the contents of the. cup are dumped for their delivery.` The base, which is closed at its back by a key-locked door (not shown) is surmounted by a magazine 10 of'transparent glass, through, which to dise position to which they are brought play the supply of the commodity, seating about the open top of the base and closed at its top by a cap 11 secured in place by boltrods 12 screwing into sockets 13 disposed about the base-top, whereby the magazine is clam ed between the latter and the cap.

Al of the operating mechanism is secured on a flanged front-plate 14, which covers the front side of the opening through the base 8 and has formed on its face to extend transversely thereof an elongated lever-housing chamber 16 of rectangular cross-section,

4having one end deflected at 17, the chamber being open throughout its length at the inner face vof the front-plate. A circular coin-insertion opening 18 is yformed in the plate 14 above the chamber 16, and said vplate also has formed u on itsrear or inner side, near the bottom t ereof, at an offset 19, an arch 20 to afford the lip of a discharge-chute, hereinafter described. A shield 21, of the general inwardly-tapering form represented,

-1s ri idl fastened at its wider, open end to the ac of the front-plate and forms at its lower part, with the arch 20, the dischargechute 22 leading to the delivery-dish 9. The

inner, closed end of the tapering` shield carries, centrally, an internally-threaded nipple 23; and the top of the shield is open lengthwise and registers with the open top of the base 8. An operating shaft 24, provided on its outer end with a hand-wheel 25, by which to turn it, is journaled in the center of they front-plate and nds bearing at its inner end in a recess 26 in the corresponding end of the nipple 23, which abuts against a forked lug 27 dependingfrom' the roof of the base 8;

and a thumb-screw 28 is passed through the bifurcation in the lug into the threaded end of the socket to bear against the rear face of the lug and afford a sup ort for the shaft at that end, being secure against accidental turning by a set-screw 29. A cup 30 formed a in a skeleton-frame 31 of the general tapering form illustrated, surrounds, at the disksha ed heads on the frame-ends, the shaft 24 witliin the shield 21, being secured on the shaft, to turn with the same, by a cotter 32 passed through it and through a boss projectmg centrally from the outermost-head of the cu device. The cup normally registers fu y with the opening in the top of the base in order that it mayobe filled by gravity from the magazine; and by turning the cu to empty its contents, as hereinafter descrl ed, 1

scribedg'and a stop-lug 34 is provided on the plate at one end of that bearing. Directly above the bearing 33 is rigidly secured on the back of the plate 14, below its flange, an arcshaped bar 35 carrying a leaf-spring 36 on one end, a bent finger 37 on its opposite end terminating in a cam 38, and between its ends a finger 39 having a deflected end-section 40 and adjacent to the finger 40 a pawl x41 is loosely ivoted to hang on the bar 35 and is provi ed on its free end with two 30 14 by a coiled spring 48.

'teeth 42 and 43. A segmental head 44 is secured through its hub 45 by a cotter 46 to the shaft 24 in osition to extend at its outer edge below t e bar 35, and bevoverlapped, for its confinement, by the fingers 39, 40. On the inner face of this head is formed to extend concentrically with the hub an opcncollar 47 which is connected from one end with a lug 147 on the back of the'plate This'spring, by its connection with the shaft 24, tends to hold the cup 30 resiliently in registration with the opening in thc top of the base. On the rear face of the head 44 is formed a segmental ratchet 49 into the path of which the pawl 41 depends. One end of this ratchet, at a point beyond its teeth, is penetrated by a pin 50, which extends entirely throu h the segmental head and, in the nor-ma position of 40. the latter, registers with the center of the com-insertion opening 18, being resiliently held against protruslon beyond the base thereof by a spring 51 engaging the rear end ofthe in and fastened at one end to a lug 52 -on the ack ofthe head 44. Adjacent to the pin another, headed, in 53 reciprocably penetrates the segmental) head, and o is engag'led at the head on its inner end b. tb e free en of a sprin 55 extending from t e lug 52.

50 An arc-shape 'groove 56 1s formed in the `outer face of the head 44 concentric with its axis and intersects a circular coin-recess 118 therein which registers with the opening 18 when the head is in its normal position. The pin 53 projects into the groove 56 at one side of the circular recess and the cam 38 extends into the path of the inner end of the pin. At-the opposite side of the circular rez cess 118 a tongue 57 (Fig.v 2) projects into the glrxoove 56 from the edge of the .opening .18.

the chamber 16 and conformmg to the general shape thereof is a lever 58 of the form most clearly illustrated in Fig. 7. 'It is fulcrumed between its ends on a vertical pin, at 59, extending transversely through the chamber and terminates at one end in an angular section 60 presenting at its extremity a shoulder 61 into the path of which the free end of the spring 36 projects; and another shoulder 62 plojects into the path of two successive teet 144 and 244 projecting from the inner face of the segmental head 44 near one end thereof. Upward movement of this end of the lever is prevented by the lug 34. The opposite end of the lever 1s offset and extends at an angle to coincide with the deflected end of the chamber 16 and has projecting from its inner face a V-shaped stud 63 in the path of the groove 56.

In the normal condition of the parts, represented in Fig. 3, wherein the cup 30 is in full registration with the'discharge from the magazine and so held by the sprin 48, (While an end of the segmental head 44 I ears against a side of the arch 20 which thus serves as an abutment to prevent undue rotation of the cup by the spring), a coin, as a penny, is required to be inserted through the opening 18 into the recess 118 to permit overturning of the cu for effecting delivery of its contents. Wit 1 the coin/inits recess 118 in the segmental head 44,'I which is normally stopped against more than initial turning by the tooth 144 upon it encountering the end of the lever 58 in 1its path, turning the shaft 24, at the handle 25, to turn the cup-frame causes the coin carried by the head to encounter the stud 63 lin its path, and by continued turning of the head the coin, in press ing against a cani-suface of the stud to force it outwardly, turns he lever on its fulcrum 59 in the direction to move its end 60 inwardly, thereby tripping it totake the shoulder 62 out of the path of the teeth 144 and 244 on the segmental head and permitting the latter to be freely turned, that is, until sto ped by abutting against the side of the arc 20 opposite that against which it normally abuts. In the resultant position of the cup 30 its contents empty into the shield 21 and chute 22 and thence drop into the delivery-dish 9, from which the operator may ather them. In attaining this position t e cup cannot be returned to its normal position until its delivery-movement has been completed, being lprevented by engagement of t e pawltoot 43 with a ratchettooth. When the ratchet 49, in so forwardly turning the cup, clears the pawl, and the handle 25 is released to permit the spring 48 by its recoil, to retract the parts to normal position, the ratchet, in the return movement of the head 44, by engagement with the pawltooth 43, kicks and turns the pawl to extend in the direction of inclination represented in Fig. 4, wherein its tooth 42 is presented to the back of the ratchet-teeth, so that any attempt, while the parts are returning to normal position, to turn them meantime in the direction for loperating the machine is prevented by the obstruction of the pawl in engaging its tooth 42 with the back of a ratchettooth. When, in forwardly turning the shaft, the inner end of the in 50 encounters the cam 38 in its path, t e pin is therebyfraudulent operation of the machine wouldbe possible, since the operator, after emptying the cup as the result of using .a coin, -could return it to partially register lwith .the discharge-opening from themagazine, thus to the position represented in Fig. 4, thereby permitting it to refill by holding it by the handle 25, in that position, and thereupon reversing the movement to empty the cup, and this fraudulent operation could be repeated until the magazine was emptied. Another means is provided, inthe second tooth 244on the head 44, for preventing fraudulent operation of the machine by the use of an annular washer instead of a coin.

Such a Washer, of proper size, Would operate the same as a com untll, 1n passing the camstudv63, the latter' registers with the hole in the washer, When the force of the spring 36 would turn the lever 58 to protrudethe stud.

through the washer, thereby presenting the tooth 244 to engage with the adjacent end of the lever in the attempt to further turn the handle 25, and thus frustrating the` operat1on.

It will be observed that in the movement of the segmental head, which moves in frictional contact, for steadying it, with the bearing 33, its groove 56 rides over the stud.

63 and the pin 53, the latter being cleared by the stud in encountering it in either direction of the movement, since the cam-end of the stud operates, in turning the head 44, to force the pin out of the-groove against the resistance of the spring 55. This, however, leaves thepin, in the normal position of the parts, as an obstruction in the groove against insertion, at the opening 18, of a Wire or other instrument along the grooveto engage the stud-equipped end ofthe lever 58 and turn it upon its fulcrum against the resistance of the spring 36 to free the segmental 'head and permit the shaft 24 to be turned,

thereby to fraudulently operate the machine. The tongue 457 at the oppositel side of the opening 18 the recovers the entrance to the groove to prevent insertionat that point therein of such an .instrument to engage the 'lever-end 60 and force it, against the resistance of the spring 36, to take that end out of the path of the teeth 144 and 244 and thus permit the machine to be operated Without usin a coin for the purpose.
