CQINfCONTROLL'ED VENDlNG-IiVIACHINE.

To allv whom, 'it .may con/cern: l

Be it known that LSIDNEY L. LONG, a citi- Zen of the United States, residing at Minneapolis, in the county of Hennepin and State of vending machines of that general class in.

which the weight of a'deposited coin serves Ism.

One objectof the invention is to providea i -machine which will insure the delivery of the articles when a coin of proper value is inserted, 3 so that therewill be no risk of the intending, purchaser losing money if he fails to prop-v erly operate or to depress the actuating-lever fully at the first attempt.

A further object ofthe invention is to pro.- vide a machine of this character in which after the operating movement of the lever Y has been started it will be impossible to force it to return to initial position until after it has completed. the full discharging movement, thus preventing manipulation of the` machine and the delivery of more than a sinf gle article in return for each coin inserted.

With these and other objects inv view, as will more fully hereinafter appear, the invention consists inthe novel construction and arrangement. of parts hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportion,si`ze, and minor details of the structurernay be made without departing from the spiritV or sacrificing any of the advantagesv ofv the invention. 4 K v In the accompanying drawings, Figure 1 is a sectional elevation of a coin controlled vending-machine constructed in accordance` v devicesv in advance of a complete depression of the operating-lever.y Fig. 4 is a detachable perspective view of the coin-receiving bucket and the catch connected thereto.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings. 4

' tained in a suitable casing 1, which may be Patented ivrach 27, 1906.

of ornamental character, and at the front of the casing is a delivery-table 2, on which the `goods, are discharged, the articles being deyivered through a suitable 'openin that is shielded by a hood 3. The front o? t 'ing also carries a slotted plate 4 for the passage of an operating-lever 5 and has a slotted he casescutcheon '6 in alinement with the endl of the coin-chute. Within the casing is a magazine 7, adapted to contain the articles to be delivered, suchas smallpackages of chewinggum or candy, the delivery being accomplished by a slide 8, adapted to suitable vguides 9, carried by the casing. To the inner wall ofthe casing is secured la cast baseplate 10, havin a bearing for the reception of one end of a s aft 11, the Ashaft being provided with a support in the form of a bracket projecting from the front Wall of the casing. To the outer end of the shaft is secured a rocker-arm 13, that extends u ward through ltheslot in the said slide and orms anactuating means therefor.

To the inner end of the shaft 11 is rigidly secured a bell-crank lever 14, having two i tegral with the base and serving as a stop for i limiting movement of the lever. lTo the upper end of the lon er arm 15 is pivoted a pawl 18, that is normal y held in a central position -or in the general plane ofthe arm 15 bymeans of a coiled Atension spring -19 that lis connected at its lower end to a lug 20, projecting from' the arm 15, the spring serving to permit swinging movement of the Ipawl in both directions. The pawl is adapted to engage the teeth of a rack 21, carried by the baseplate 10 and arranged on a curved line struck from the aXis of the shaft 1 1, the pawl traveling freely over the teeth as thelever is moved in both directions, but when 'once in mesh with the rack-teeth serving to fpositively pre'- vent any return movement a ter the movement in either direction has commenced and the return movement cannot be permitted under any circumstances until a full stroke of i the lever has been accomplished. -Y To the shorter arm of the bell-crank lever 14 is pivoted a bell-crank lever 25, the longer arm 26 of which is provided at its outerend with a coin-receiving cup 27, disposed at the end of the coin-chute 28, -the bottom lof the coin-cu having a slot of such size as to permit of t e passage of coins orvother articles of smaller diameter than that of the coin necessary to operate the machine. The longer arm of the lever is connected to the lug 20 by means of a light tension-spring 2S, and the shorter arm 29 of said bell-crank lever is in the form of a catch that is adapted to engage with the rear end of the operating-lever 5.

The operating-lever 5 is loosely mounted on the shaft 11, being heldin proper position on said shaft by an auxiliary sleeve or collar 32,

and the front end of the lever is normally held in elevated position by means of a strong tension-spring 33, extending between the lever and a lug carried by the frame, the lug serving also as one of the supports for the frame. The rear end of the lever is pointed in order that it may be properly engaged by the catch 29, and downward movement of the rear end of said lever is limited by a pin 37, carried by the arm 16 of the bell-crank lever 14, so that the stress of the spring 33 is thus transferred in part to the bell-crank lever 14, and the upper arm 15 of the latter is held against the stop-lug 17. When the parts are in normal position, the lever may be depressed without effecting any movement of the ldischargeslide until after a coin has been inserted. On the insertion of a coin, if of proper value, the coin will pass down through the chute vand will be caught in the cup of said lever, its vweight overcoming the stress of the light tension-spring 28 and causing the catch 29 to engage the rear end of the operating-lever 5. When the lever is depressed, its rear end will carry the catch 29 with it, and this movement will be transmitted to the bell-crank lever 14 and through the lever 14 to the shaft 11 and the delivery-slide, causing the discharge of the lowermost article in the ma azine. The discharging movement of the ever causes the pawl 18 to engage with the teeth of the rack 21, and during this movement the pawl is shifted to aposition at an angle to the general plane of the arm 15, so that the radial distance between the axis of the shafts 11 and the end of the pawl when the latter is engaged with the rack will be less than the normal distance when the pawl is straight, sothat when once the pawl is engaged with the rack it will be impossible for any backward movement to occur unless some of the parts break, and if the pawl is released before its `full downstroke is accomplished it will remain in the position to which it has been moved, so that the downstroke may be completed at any time, and thus secure the delivery of the article and avoid danger of the loss of the money inserted and the non-delivery of goods. In order to prevent the disengagement of the catch 29 from the end of the operating-lever, the lug 17 has a threaded opening for the passage of a screw 40, having a lock-nut 41. The end of this screw is disposed immediately above the catch 29 during all the time the latter is in engagement with the operating-lever after the movement of the latter has been started, and it will be observed that the outer face of this catch is disposed on a curved line struck from the center of movement of the shaft 1 1 so that the screw will at all times be in position to prevent disengagement of the operating-lever from the catch should the operating-lever be moved for only a portion of its stroke. On the release of the operating-lever if the full stroke has been accomplished the pawl will move to the opposite angle and will travel rapidly over the teeth. of the rack 21 under stress of the heavy tension-sprinfT 23. The coin deposited in the cup 27 comes into contact with a spring 42 at a point near the limit of downward movement of the operating-lever, and the coin will thencebe elevated, or rather will be held from further downward movement, while the cup continues its downward movement and effects the discharge of the coin.

In the coin-chute is placed a magnet 45, which serves to deflect any paramagnetic disk or slugs which may be inserted in the machine.

Having thus described the invention, what is claimed is- 1. In a coin-controlled vending-machine, the combination with a delivery-slide, of a shaft, means for operatively connecting the slide and shaft, an operating-lever loosely mounted on the shaft, a bell-crank lever secured to the shaft, a spring-held pawl carried by one arm of the bell-crank lever, a rack for engaging the pawl, the distance between the fulcrum-point of the lever and the point of the pawl when the latter is disengaged from the rack, being greater than the distance between said fulcrum-point and the rack-teeth, thereby preventing rearward movement of the pawl in advance of the complete stroke of the bellcrank lever, a pivotally mounted coin actuated pawl carried by the shorter arm of the bell-crank lever, the outer face of said pawl being on an arcuate line approximately concentric with the axis of the shaft, and an adjustable screw serving to prevent release movement of the pawl until the completion of the delivery operation.
