UNITED STATES CHARLES E. ELKINS AND THOMAS B. SMITH, OF WAGO, TEXAS.

VENDING MACHINE.

Application filed October 23; 1924. Serial No; 745,438.

To all whom it may concern:

Be it known that we, CHARLES E. ELKINs and THOMAS B. SMITH, citizens of the United States, residing at lVaco, in the county of McLennan and State of Texas, have invented certain new and useful Improvements in Vending Machines, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to vending machines, and particularly to machines for vending pencils or like articles The general object of the invention is to provide a very simple, easily operated machine of this character which includes a valve-like receiver having a shape approximately the same as a pencil and adapted to receive the lowest pencil of those contained within the magazine and, when oscillated, to deliver said pencil and prevent the other pencils from being discharged.

A further object is to provide improved means whereby the device may not be actuated to discharge a pencil unless a coin has been deposited. V

Other objects will appear in the course. of the following description.

Our invention is illustrated in the accompanying drawings, wherein a Figure 1 is va front elevation of a pencil vending machine constructed in accordance with our invention, the lower part of the machine being in section;

a I Figure 2 is a fragmentary vertical section showing the manner in which the pencils are discharged v v Figure 3 is afragmentary elevation of the coin operating means, the magazine being in section; V V

Figure 8 isa likeview to Figure 7 but showing the receiver rotated to discharge the pencil; l a

Figure 9 is a. fragmentary elevation of one end of the case 10 showing the operating means on the exterior of the case.

Referring to these drawings, 10 designates opposite walls of a case or cabinet forming part of the vending machine. lVithin this case or cabinet is disposed the pencil magazine 11, and disposed below the lower'end of the case or cabinet is a pencil chute 12. The forward and rear'walls of these parts 11 and 12 are connected by means of the intermediate, outwardly bowed portions 13, as illustrated in Figure 7. These outwardly bowed portions 13 define a chamber within which is disposed an oscillatable receiver 14. This'receiver is cylindrical in cross section, except in its middle or that portion which extends through the magazine 11 or more correctly through the part 13, and is hollow sothat the middle portion of the receiver, as illustrated in Figure'T, forms a semi-circular receptacle, the totaldepth of the receptacle being equal to the diameter of a pencil A. -One extremity of this receiver is oscillatably mounted in a bearing 15 carried upon one sidewall 10 and the opposite end of the receiver is escillatably supported, as will be now de scribed. 7 I V Mounted in a bearing bracket 16 uponthe opposite side wall of the receiver is a longitudinally extending shaft or pin 17 which enters the adjacent end of the receiver 14 and thus supports the latter and constitutes a bearing therefor. This shaft ortpin 17 is held to the bracket 16 by means of a transverse pin 18 which preventsthe shaft 17 from rotating and prevents from any sagging movement. Any means might be used to firmly supportthe endlofthe shaft 17 so that itwill vbe directly in line with'the reangular extension 20. This extension 20 isprovided, as illustrated in .Figurel4, with a laterally projecting curved lug 21.

ceiver 14 and'act as a bearing therefor; A,

Con I fronting this arm or extension 20 is a second arm 22, the lower end of which has a sleeve 23 which rotates loosely upon the bearing shaft 17, and the inner face of this arm is provided with a slight cup-shaped coinsupport 24 which has the. shape of a segmen of a circle thesize ofla coin. v Disposed immediately above the normal position of this cup-shaped coin support 24 is a coin chute 25 which extends downward from the I exterior of v the vending ,machine in any suitable manner, the lower end ofthis chute being angularly cut away, as at 26, so that the rear wall of the coin chute-islower than the front wall: and approximates the upper edge of the cup when the arm 22 is in its rearward position. Th arm--22'is provided with a laterallyprojecting rod 27 to which an operating lever, arm or other operating device exterior to the vending maclnne'mayibe connected so that upon an operation of thisoperating device in one direction'the arm 22l'will'be drawn over in a counter-clockwise direction in Figure 4.-

A coiled spring 28 is connected at one end at one end is attached to the bearing 15 and atthe-other end to the receiverand acts also to return the recciver to-its normal posit io-n. The'spring 28 also acts to force the I sleeve 23 forward to force thearm 22 toward thearm 20"sothat but little more spaceis lefthe-tween the inner faces of'the two-arms than is necessaryto receive a coin in the normal position ofth'eseparts. When, however, the arm 22 .is' turned over'to the position'shownuinuFigure a cam-shaped face 30 which is at the lowerend of the ar1n22 engages a pin ill and this forces the arm 22flaway' from the'arm320against the action ofith-e spring '28 when the arms 20" and are in the'dotted line position shown in Fig-- .ure 5, thus .pern'ntt ng the dropping out. of

thecoin in the normal. positionof the. parts. The

arms

22 and 20 are CllSPOSQ'ClEIS 1llustrated llrFlglH'e l; thearm 20 being some-- what inadvance of the arm'22 and the arm 22*being in such position that the cup 2 l'is disposedimmediately beneath the rear portion 'of the coin chute 25; vAt this time the receiverl 'iis'di'sposed as illustrated in Fig-1 are with: its open face up,-and the lowest pencil A of'the series of pencils within the magazine 11 is resting. in this receiver.

If now a coinbe deposited in the'chute 25, it drops down the chute and lands upon the'cup 24. If now thearm 22 be vmoved forward by means of any suitable. operating mechanism connected with the rod 27, the C0111 will move along until itstrilie's'thelug 21, and after that thearm 20 Will move with the arm 22. This continues until the arms are in a depending. position, as illustrated in Figure 5. The coin up to this time has Ueen firmly clamped between the arms, but when tlnsposition is reached the pin 81 engaging against the cam edge '30 forces the sleeve 23 outwardly, thus separating the two arms so that the coiirm ydrop out; the" iis that the arms have reached'their depending position, the receiver lthasbecome completely-overturned and drops the pencil out, as shown in Figu're 8, the rounded bottom of the receiver being now upward preventingany other pencil from dropping downward through the pencil chute. As soon as th-e'coin has droppedout, the spring 29 will act to return the member 14: to its initial position, and as soon *as the forceha bee-nreleased from-tl1e-arm-22, this-arm will" return to itsnormal position. As soon as the receiver returns to itsnormalposition, a new pencil will dropv into theireceiverand all ready'for -another actuationz' The coin, of course, dr'ops into a-suitable' coin boxlorated helow the arms 20 and 22.-

W hile we do not wish? tohe limited to any particularform of ope "tingmeans ton-the arm L l r," we have illustrated a rod- 27-hounectad to the operattng member 22 crank- ..iiaped at itsend to extend through. a slot -32forined in the case 10;: We have illustrated this rod 27 as being-formed at its BXCI-QDP' ity with-a guide whereby the rod may he osrilla'ted' to'oscillate the-arm 22, but we do not wish to be limited to this as any other means might be used for this purpose.

We have not endeavored in these drawings to illustrate the general design or form of apencil- Yendinggmacl-iinebut only such parts as are necessaryfor an understanding of the operation and actuation of the device,

and while the partsas illustrated have been found particularly"simplebut yet efiicient, we do not wish to be'limited to the details of"construction asthese obviously may be modiiied .in uiany ways without departing two arms when they have reached a pre determined point to thereby permit the dropping of the coin.

2. A coin controlled mechanism including an ,oscillatable member, an upwardly extending arm on the oscillatable' member, a second upwardly extending, jarm approximately confronting the first-named arm and oscillatably mounted, means connected to said second named arm whereby it may be manually oscillated, a coin chute discharging immediately above the normal position of'the second named-arm, a segment-shaped coin cup carried by the second named arm, the first named arm having a lug disposed in the path of movement of the coin carried by said cup whereby said arms may have unitary movement, and means for causing the separation of the arms when the arms have been oscillated to a depending position to thereby permit the discharge of the coin.

In a coin actuated mechanism, an oscillatable member having an upwardly extending arm on one end, a second upwardly extending arm approximately confronting the first named arm and oscillatably mounted, means connected to said second named arm whereby it may be manually oscillated, a coin chute discharging immediately above the normal position of the second named arm, a segment-shaped coin cup carried by the second named arm, the first named -arm having a lug disposed in the path of movement of the coin carried by said cup whereby said arms may have unitary movement, means for causing the separation of the arms when the arms have been oscillated to a depending position to thereby permit the discharge of the coin, and means for returning both of said arms to their normal position after the coin has been discharged.

4. A coin controlled mechanism including a tubular oscillatable member, a bearing supporting one end of the tubular member, a fixed shaft extending into the other end of the tubular member and supporting it for oscillation, the last named end of the member having a radially extending arm, a sleeve mounted upon the shaft and having a radially extending arm approximately confronting the other arm, means for manually oscillating the last named arm and sleeve, a spring yieldingly urging the last named sleeve toward the first named sleeve and yieldingly resisting rotation of the last named sleeve, means yieldingly resisting the rotation of the first named sleeve, and means for causing a movement of the second named sleeve away from the first named sleeve when the arms are in a depending position comprising a pin mounted upon the shaft, the sleeve having a cam face engaging with said pin to cause separation of the arms when the sleeves have rotated sufficiently to carry the arms to a depending position.

5. A coin actuated device comprising two confronting oscillatable members mounted for rotation upon a common axis and having radially extending approximately confronting arms, one of the arms being provided with a coin cup and the other with a lug disposed in advance of the coin received in said cup, means for oscillating the coin cup carrying arm to carry the coin into engagement with the lug to thereby cause unitary oscillation of the two arms, and means for causing a lateral separation of the two arms when the arms have reached a depending position to thereby cause the diseral separation of the two arms when the arms havereached a depending position to thereby cause the dlscharge of the com 1nc-ludmg a member exerting a camming action on one of said oscillatable elements to our signatures.
