PATEMNT ERNEST W, PETERSON, OF KANSAS CITY, MISSQURL 'VENDXNG MACHINE.

Application mea May is, serial no. caesar.

To all 'wiz-0m t may concern:

Be it known that l, ERNEST W. PETERSON, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of 'Missourh have inventedl certain new and useful Improvements in Vending Machines, of which the followingis a specication.

My invention relate-s to vending machines of that class in which different articles of merchandise, such as gum, chocolate, etc., may be independently vended in the same machine by depositinga coin and operating a single lever or its equivalent.

One object of the invention is to provide a machine of this character which is inexpensive to manufacture, compact in construction, and free from springs so that it will not be likely to get out of order.l

A further object is to provide a vending machine in which a deposited coin is utilized to actuate the mechanism for the purpose of ejecting an article of merchandise from the machine, said coin being released after delivery of an article and the machine becoming inoperative until another com 1s deposited.

Other objects will hereinafter appear, and in order that the invention may be fully understood, reference will now be had to the accompanyingdrawings, in which:

Fig. l is a vertical sectional view of the machine viewed from the rear.

Fig. 2 is a vertical cross section on line 'II- II of Fig. 1.

Fig. 3 is an enlarged fragmentary section on line III-III of Fig. 1.

Fig. 4 is a rear elevation of the parts disclosed by Fig. 3.

Fig. 5 is a detail plan view of one of the ejectors.

Referring now in detail to the various parts, 2 designates a case which in the present instance has a plurality of verticallydisposed compartments l in which the articles A are stacked. Access is had to the compartments 4 to load the same by a glass or other suitable door 6 connected to the top of the case by hinges 8. Any suitable lock, not shown, may be employed to secure the door 6 in closed position. The lower ends of the compartments 4f communicate with trays 10 into which the ejected articles are delivered and from which they can be readily removed by the vendee.

l2 designates a pluralityof coin chutes equal in. number to the compartments i and extending from the top wall 1st of the case 2 into close proximity with a rocleshaft 16 in the lower portion of said case 2. liach coin chute 12 comprises a stationary upper section 18 and a swiuggable lower section 2G, which latter is provided with a bearing 22 loosely mounted upon a stationary shaft 24 extendingl across the inner rear portion of the case 2.

Each swingahle coin chute section is, preferably, open at its rear portion which .is provided with inturned marginal flanges 25 for guidingl a coin such as B downwardly upon the underlying boss 26 fixed upon the rock shaft 16. The lower front margin of each swingable coin chute section 2O has turned up portions E28 to receive the inturned rear terminals 30 of an ejector 32, the for ward portion of which rests upon the bottoni Se of the compartments fl. lllhe ejectors 3Q, for the salte of economy, are preferably made of wire of suitable gage Yand bent into, j nproximately, itl-form and their forward portions normally rest adjacenttolthe rear portions of the lowermost articles A as best shown by Fig. 2. The rear wall 36 of the compartments #l has slots 38 through which the ejectors 32 may pass when eject innv the lowermost articles A.

Each boss 26 carries integral front and rear arms 4:0 and 4Q, respectively, the former to normally hold the respective swingable coin chute section. 20 back against a stop Maand the latter to cooperate with the respective coin B in swingingn said section 2() forwardly to eject an article.

The rock-shaft 16 is mounted in cylindrical bushings journaled in bearings 52 in the side walls 5e of the case 2. @ne end of said rock shaft 16 extends outwardly through one of the side walls 54: and is bent upwardly to form a handle 56, the upper portion of which projects above a `niard 58 fixed to said guide wall to protect said handle. rlhe guard 58 has a stop 60 to limit the. baeltward'movement of the lever 56, the shaft 16, and the parts mounted upon said shaft The shaft 16 and the parts mounted there on are normally held in backward position as shown by Fig. 2, by a counterweight 62 suspended from one end of a cable 64 running over a sheave 66 and attached at its opposite end to a lever 68 fixed to the rocio shaft 16. The sheave 66 is journaled on the stationary shaft and held 'from lateral. movement by collars 70 lixedly mounted upon said shaft 211'.

Briefly the operation is substantially as follows: On depositing a coin in one of the coin chutes l2, Vlor instance the center coin chute, said coin descends until cheeked by the centrally-disposed boss 2G. The vendee then grasps the handle 56 and swings the .same forwardly until checked h v the lever GS conttuftingthe bottom "wall T!V oit the case 2. The Ylbrward swing of the handle 51) rocks the shatt 1G, together with the parts mounted thereon, causingl the intermediate arm 42 to in'ipinge against the coin and in turn force it against the tront Wall of the respective coin chute section l2, thereby swinging the same forwardly and causing' the associate ejector 32 to push the article A in its path into the tray l0. On releasing.;` of the handle 56 the counterweight 62 rocks the shaft 16 barlnvardly to normal position and causes the intermediate arm 40 to restore the actuated coin chute section 2O against its sto]V The intermediate. arm 42 also releases the coin B and permits the saine t v'all from the boss 26 into the bottom of the case 2. lllhen the intermediate arm l2 rocks forwardly against the coin as above stated, the companion arms 4t2 are also rocked forwardly but as their associate coin chute sections 2() have no coins to impinge against, said arms ll2 pass through recesses 76 in said sections 20 and thus tail to actuate the same and the associate ejectors 32. It the vendee.,l desires to obtain three articles snnultaneouslyim he places a coin in each coin chute, Where-- upon one operation ot" the handle 56 will ellect the siluultanemls delivery of the three articles. Y

Freni the l'm'c/ coixigrA description it will be understood that have provided a vending` machine embodying` the advantages above pointed out, and While l have shown and described the preferred construction, combination and arrangement ol parts, l reserve the right 'lo make such changes as properly fall within the spirit and scope ot' the claim.

Having thus described my invention, What l claim and desire to secure by Letters Patent, is:

In a vending` machine, a case for holding articles to he vended, an ejector for deliver'- ing the articles, a coin chute mounted in the case and consisting ot an upper stationary section and a lower section swingably mounted at its upper end and pivotally connected at its lower end to said ejector to actuate the saine, means for supportinga coin .in said chute, al member to engage the supported coin and thereby advance the chute and the ejector on a delivery stroke and release the coin on the return stroke, and another member for returning the chute and the ejector to normal position on release of the coin.

ln testimony whereof I allx my signature in the presence of two Witnesses.

ERNEST W. PETERSON.
