VENDIN G-IVIACHIN E.

massoa.

To all whom it may concern Be it lmown that I, E IJAH F. SPAULDING, a citizen of the United States, and resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Vending- Machines, of which the following is a specification.

This invention pertains to improvements in coin controlled vending machines, and has for its objects to provide simple and efficient means to permit vendible articles to be delivered upon the insertion of a proper coin and the operation of devices controlled by such coin.

The invention further comprises novel details of improvement and combinations of parts that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings'forming part hereof, wherein,

Figure 1 is a rear elevation of my improved vending machine, parts being removed; Fig. 2 is a vertical section substantially on the line 2, 2, in Fig. 1, illustrating a coin in position beyond the section line and the machine ready for operation; Fig. 3 is asimilarview showing the parts in operated position, and the ejecting lever or arm locked by the weight after the depositof a lowermost article of a stack; Fig. 3 illustrates a detail hereinafter referred to Fig. 4 is a plan view of the controlling I mechanism, parts'being omitted; Fig. 5 is a detail section substantially on the line '5, 5, in Fig. 4; Fig. 6 is an enlarged detail plan view of member 16; Fig. 7is a detail hereinafter referred to; Fig. 8 is a front view, the casing being removed; Fig. 9 is a front elevation of plate 32; Fig. 10 is a detail section, and Fig. 11 is a detail section.

Similar numerals of reference indicate corresponding parts in the several views.

The numeral 1 indicates a suitable casing or frame having chutes 2, of any suitable construction, adapted to contain articles 3 tobe vended, and at 4 are weights adapted to slide in said chutes and to rest upon the articles 3. Ledges 5 at the bottom of each chute retain the lowermost article, the rear and front portions of the chute being open to admit the lowermost article to be de-.'

livered, as at 3", in a well known manner.

In the form illustrated, the articles as de- Specification of Letters Patent.

A Application filed December 28, 1914. Serial No. 879,244.

' liveredare adapted to pass down a passage 6 in the casing to rest upon an exposed sup porting surface 7 At 8 is a coin slot for each set of the delivery devices thatv may be provided in the machine. Within the eas- 9 rests, whereby said frame may be slid into,

and from the casingthrough the rear door 1, which may be secured to the casing in any suitable manner. Upon the side members offrame 9 a rock shaft 10 is journaled, upon which shaft a weighted stop 11 is secured, shown adapted to. engage a rear bar 9 of frame 9 to retain said shaft in normal position.

Upon shaft 10 one or more levers or arms 12 are pivotally supported respectively beneath the chutes2, and suitably spaced apart according to whether two or more chutes and delivery devices are provided in one casing. Wherethe machine is provided with a single chute and coin slot, one of the levers 12 will sufiice, two of such levers and associate parts being shown in the accompanying drawing. The levers 12 are so hung that 'they normally rest at their upper portions against the bar 9 of frame 9, and such upper portions of said levers are shown normally substantially at one side of the vertical plane of the rear of. chute 2. The levers 12 are adapted to pass under the corresponding chute to push the lowermost article from such chute through its opening 3* when the lever is caused to rock forwardly by a coin interposed between such lever and devices controlled by a push rod or the like 13. For this purpose I have shown the upper ends .of levers 12 each provided with an ejector 14 having the projecting portion 14: adapted to engage the lowermost article of a corresponding stack to eject the same. Ejectors 14: are shown pivotally supported upon pins or the like 15'carried by the levers 12, said ejectors having cars 14* receiving said plus,

which ejectors are suitably is slotted at 14 (Fig. 8) to receive levers 12, whereby, said ejectors are retained from lateral movement upon said levers and are adapted to swing thereon, In .theirnormal positions said,

' ejectors may'rest, against the levers to retain the projections 14 i stack has been ejected, and, weight 4 rests upon the ledges 5, a" projection 4 of said weight will be brought into position to 'engage a projection 12 of the corresponding lever 12 (Fig. 3) to prevent said lever. 12

from returning to norm al'unt il said Weight is removed. I

The'means I have shown for operating the levers l2are as follows: The lower ends 12 of levers12 normally rest above an inclined coin-receiving sliding member 16, to which 1 6 whichrod slides freely throughv a suitable guide or the like in the front wall ofcasing 1., Said member is shown guidedby means of rollers 17', carried upon lugs at the ends of saidmembersadapted to travel in guiding slots 18 in the sidewallsor plates. .of frame 9, said 'rollers and the rod 13 sitlon within frame 9. .Member 16 is pro- "yer-'12 for the passage or deposit -of-a coin"- -therethrough, which opening 'is wider than the diameter of a proper coin. 1 The proper be delivered upon the inclined;

vided with an opening 16*beneath'each le- 'coin 19 is to I surface of 'member16 to slide thereon and be, temporarily. retained beneath thejcor'rereturn stroke of sponding lever 12, as indicated at 19 in Fig.

2. For'such purpose 1 have shown'member' '16 provided with guideways 22 shown I formed between spaced members 20 and 0n'frame-16 (Fig. 6). Themember 21may be a. magnet to attract a spurious token" guideway 22' through an opening 23,,

in member 16 to*dislodge such token-and prevent it from passing under lever 12.

To" temporarily retain coins 12 in order .to operate the corresponding lever 12 when 'member"16 is pushedmwardly,I'provide stops'23, 24c (Figs'l and 6) on member 16 on opposite sides them, to temporarily retain such coin above the corresponding opening 16*, flatwise un der the corresponding lever. 12. At least one stop of"each"pa1r,-such" as 24, is preferably adjustable, and is shown in the form of a screw, meshing in a threaded openingin frame 16, whereby -the head-of the screw may be raised or'lowered to regulate the behind the lower- 6). In such the push rod 13 is secured, 'as to the part maintaining frame 16 in proper sliding po'- part 119 of weighted I member 16 is. pushed inwardly, be] rocked when phish rod 13. is released saidweight under levers;

riding along the same will cause retainer laterally to withdraw its pro-- -jection's25 from beneath any coin or co s of the openings ,16, said stops beingf so spaced apart as to prevent amoinisliding, between passageflthereunder of a coin of proper thickness into position between a pair of posed coin retaining arm 25 for each open.-

Said members are shown slotted ing 16?. at 25 and receiving the screws 24, whereby said members are retained and guided; Said members 25% are so located that, in their normal positions, they overlap a lateral edge of the corresponding opening 16, therebyreducing the normal working area of such openings,'whereby the coins may rest upon the material at the edges of such openings, partly upon the frame 16 and partly up nthe projections 25 (Figs.'1 and position of the parts a coin 19 may be retained beneath an arm 12 'of a lever 12 (Fig. '2), whereby when frame 16 is pushed inwardly by push rod 13, the

coin will engage the arm 12 and tilt the a transversely slidlever," whereupon the projection 1 1- of ejector 14 will engage the lowermost article of the corresponding stack and eject it (Fig.

by engagement with a pin A spring 26,

( on member 16 engaging a projection 28 on retainer 25, normally maintains'retainer '25 pushed to the left in ment with one or more stops 24:. -Member J 16 1S' shown pivotally connected, by a pin with aforked or slotted I Fig. 6, in engage- 16 (Figs. 2 and 8),

arm 11, whereby. when and weight 11 lifted, so that shaft 10 will will cause themem'ber'16 to. return to normal, the shoulder 11" of said weight then 5 To operate the coin retainer 25, upon'the member 16,- 1 have shown f resting upo bar 9"of frame I said retainer provlded. at one end with a dog 29, shown pivoted to retainer 25 at 30,

which dog is adapted, when retainer "16 is to' ride up and beyond' an inclined projection 31 secured on frame 9,

which projection is for- Twardly inclined at 31 (Fig. 7), whereby on the return stroke of ,member 16 the dog 29 pushed inwardly,

the inner face of will engage saidinclined face'31 and'by 25 to slide guiding the coins from'slots 8 to the guide I .ways' 22 on member 16. I have shown a plate 32 normally located ad acent, to the perm t such coin or coins As soon as the dog I I front plate or wall 9 of frame 9 and guided to slide on said frame by means of lugs, or the like 32 resting on the edges 9 of frame 9. Stops 32 on plate 32 retain said plate normally spaced from wall 3 providing space a for the passage of coins and tokens. Plate 32 is shown provided with openings at 32 opposite each guideway 22 of member 16 (Fig. 1) to permit the entrance of coins to said guideway. Member 16 is shown provided with prongs or projections 16 adapted to pass through the openings 32 of plate 32 into the path of coins from slots 8 when the parts are in their normal positions, to

guide said come .upon the guideways 22 of member l6,as shown in Fig. 2. To assure that the coins will not pass down through space a, but will be lodged upon the projections 16 to be guided thereby into the openings 32 said projections are suficiently long to pass across the space a (Fig. 2). For such purpose I have shown front plate 9 of frame 9 provided with openings 9 to receive the projections 16 (Figs. 2 and 8). Member 16 is shown as movable relatively to plate 32, and is adapted to move said plate with it, to assure withdrawal of projections 16 from space a when member 16 is first moved, to prevent coins from then being retained upon the projections 16 dur-- ing operations of the machine, which coins can then pass below and will be guided by ways 33 (Figs. 1, 2 and 3), downwardly to a coin or token outlet 34 of the casing, to be returned to the customer. 1 have shown member 16 provided with projections 16 at its forward corners, to engage lugs or projections32 on the inner side of plate 32, the last named'projections being so spaced from plate 32 that the projections 16' may move freely therebetween, and when member 16 is sufficiently pushed inwardly the plate 32 will be carried with it by said projections. Plate 32 will be pushed outwardly with member 16 on the return stroke, by the engagement of member 16 or its projections 16 with said plate.

Upon plate 32, in vertical alinement with the corresponding guideways 22 of member 16, fingers 35- are pivotally supported at 36, upon brackets 37 on said plate. Fingers 35 are provided each with a projection 35 adapted to extend through a corresponding corresponding guideway 22. The fingers 35 Y are weighted to normally rest upon stops 38 on plate 32 (Figs. 2 and 3) with the projections 35 extending through slots 32 respectively. The fingers 35 also have projections 35 above projections 35 and adapted, when the fingers are tilted, to pass through openings 32 of plate 32 respectively. When a enter the hole in the token by reason of theimpetus given the finger by the stroke of the token on the projection'35 thereby temporarily retaining such token on finger 35f, to prevent such token from reaching the projections 16, so that when member 16'and plate 32 are next pushed inwardly, and the projections 16 are withdrawn within .or behind plate 32 (Fig. 3), such token will be caused to drop below through space a, and out through opening 34. The distance between the plate 9 and the ends of projections 35 and 35 when a proper coin engages projection 35*, is such that the coin can slide between plate 9 and said projections, as illustrated in Fig. 11. If a token way 22, will immediately be attracted by the magnet 21 and be drawn to one side topass through opening 23, to prevent such token from passing beneath the corresponding lever 12. v

E ach lever 12 is shown provided with a pro ection 12 extending forwardly in posi-.

tion over finger 35, and normally in such position as to permit the corresponding finger 35 to tilt, to permit the passage past the finger of a proper coin, but said projection 12 is'in such position that if a washer tilts finger 35 so that the projection 35 enters the hole in the washer, the latter will be caught upon such finger and there temporarily retained because finger 35 will then engage projection 12' and prevent said finger from tilting sufliciently to release the washer, the finger then riding under projection 12 when plate 32 is pushed inwardly, the washer being caused to fall below by reason of the reciprocation of plate 32. The position of projection 12*, also, is such that when lever 12 is retained in the forward position by the projection 4 of weight 4, (Fig. 3) the corresponding finger 35, if tilted by a coin or washer, will engage said projection and one or the other of'the projections 35, 35 will obstruct such coin or washer, whereby su h coin or washer will be directed ness 01 22, (and if it is not attracted by the magnet), it will slide freely between said stops and pass off the rear end of member l6 into a chute leading to the token outlet 34 (Fig. 2). Chute 0 may be secured upon the rear wall of coin receptacle 6, and said receptacle may be removably retained in casing 1 by means of side projections on said chute entering grooves l in the side walls "of said casing, or in any other suitable or welllmown manner.
