VENDING DEVICE.

SPECIFICATION forming part of Letters Patent No. 493,805, dated March 21, 1893.

Serial Ha li-34,894. (No model.)

To all whom it may concern.-

Be it known thatI, JOSEPH GULLEN AYER, of Boston,in the countyof Suffolk and State of Massachusetts, have invented certain new and usefullmprovements in VendingDevices, of which the following is a specification.

My invention relates to that class of apparatus in which articles of known or determinate dimensions, such for example as envelopes, postal cards &c.:are made capable of delivery by the insertion of a coin in such relation with the mechanism as to cause or permit the ejectment of such articles as the consequence of the insertion of such coin.

Its object is to provide apparatus of the class mentioned capable of delivering articles of differing dimensions and value by one operating mechanism, which will be positive in its operation, simple and durable in its construction and adapted to a wide range of use of the character indicated. 1 attain this object by the mechanism illustrated in the accompanying drawings in which Figure 1 is a view in perspective of the exterior of the case containing the mechanism. Fig. 2 is a view of the door that confines the mechanism in the case, detached therefrom. Fig. 3 is a view of the upper tray or article receptacle, removed from the case, with apart of. one side broken away to exhibit parts of its interior. Fig. 4 is a view of the lower tray or article receptacle, removed from the case, with one of its sides partly broken away to show portions of the interior. Fig. 5 is a view in perspective of the mechanism, frame or cage, removed from the case, and containing the operating mechanism, having a portion of its rear wall broken away. Fig. 6 is a vertical sectional view of the entire appa ratus on the line 1, 2, Fig. 1. Fig. 7 is a detailed view in perspective of the cross head with its levers their coin receivers and their ing for the introduction of coins, this coin slot ct having a longitudinal axis slightly greater than the diameter of the largest coin by which the mechanism is designed to be operated also having a detachable door B capable of being secured to the case, as by the introduction of the pins 1). b in the case into the recesses c c in the top of the door and the bolt of the lock d into the slot e in the case, at the bottom, so as to securely confine its contents within the case.

In the front of the door B is an opening sufficient in size to admit of the articles sold to be ejected or withdrawn through it as also to permit the operating knohPto be grasped and withdrawn.

C is the upper article receptacle or tray which when in its proper position occupies the upper interior part of the case A. It is open at its top side for the introduction of articles to be sold therefrom, which articles are placed therein one above the other. I place above them a suitable weight as o by which they are pressed downward; at its bottom the tray O is provided with the ledges f f, which ledges extend forward beneath the front wall 0 of the tray. They support the articles in the tray and serve as guides to diroot the bottom article forward to the opening 9 in the-tray through which itis ejected or withdrawn; atthe bottom of the front wall 0 of the tray isthe slot or opening g of greater size than the largest article designed to be passed through it; vertically attached to the wall 0 by the set screwst' t' passing through the slots j j is the adjustable gage plate h, which plate I preferably attach to the innerside of the wall as shown. This plate can be raised or lowered at will to widen or contract the opening 9 to conform it to the dimensions of the article to be ejected or withdrawn through it and can be retained, after adjustment, in position by the set screws The lower edge of the plate in connection with the ledgesf f form lips between which the article sold from the tray passes. Attached to the rear wall 0 of this tray in the coin chute Z, of which is is the inclined portion lying immediately beneath the coin slot a when the tray is in place in the case. Z is the vertical part of the chute.

D is the lower article receptacle or tray, which when in its proper position, occupies the lower, interior part of the case A resting upon and supported by the posts 8 s s s attached to the case. In the upper edge of its front wall m is the recess 1?. of sufficient depth to form in connection with the lower edge of the front wall F of the hereinafter described mechanism cage E a slot or opening to permit the articles sold from this tray to be ejected or withdrawn throughit. 0 isits rear wall which may be vertically fixed at any desired point in the tray; within the walls of the tray is the horizontal table or follower g attached to the upper end and resting upon the helical spring 7", which spring for the purpose of economizing space I prefer to make conical in form. The spring r rests upon and is supported by the bottom of the tray; the articles to be sold from this tray rest one above the other supported by the table q and spring 1". The upward thrust of the spring on the table causes the articles supported thereby to be elevated in succession as the uppermost article is ejected or withdrawn from the tray. The under side of the cage E confines the articles within the tray, and limits the upward thrust of the spring '1".

E is the before referred to mechanism cage or frame which when in its proper position in the case occupies its central portion resting upon the tray D and itself supporting the tray 0.

()f the cage E, F is the front Wall, G with its bosst constitutes its rear wall; intermediate between F G is rigidly vertically arranged the butment wall H. These walls F, G and H I connect together by the four rods I I, I I; these rods and walls constitute the mechanism cage. I do not confine myself to the use of the rods in connecting the walls F G H as bars, side walls or other suitable devices may be employed.

Central in the wall F. H. are openings to. it through which supported by the walls and guided by the sides of the openings slides and is reciprocated the operating rod L. The rod L extends through the front wall F of the cage terminating in a knob or suitable handle as Psuch as may be readilygrasped by the hand of the operator to draw forward the operating rod L; the pin M passes vertically through the rod L at a point intermediate between the walls F, H, its upper limb to extending upward in front of the hereinafter described sliding carriage J, its lower limb to extending downward in front of the sliding carriage K hereinafter to be described. Between the pin M and the rear of the wall F encircling the operating rod L and retained in position by them is the helical spring N, the backward thrust of which when it has been closed by the drawing out of the operating rod L, against the pin M automatically retracts the rod L;

angles to it is the cross head 0. This crosshead retains and supports in the longitudinal slot 0 at its upper end by means of the pin y the upper lever, Q the pin y acting as the fulcrum of the lever. The cross head 0 supports and retains in the longitudinal slot 0 at its lower end by means of the pin 2 the lower lever B, the pin 2 acting as the fulcrum of the lever. The levers Q R are weighted at their front ends and their extent of tilting movement may be regulated by their form and the depth and form of their respective slots; the butment wall H which limits the forward and backward travel of the operating rod L as hereinafter described is provided with suitopenings S, S through which the forward parts of the levers Q R. travel as the operating rod is reciprocated secured to the butment wall II and passing through openings in the cross head 0. Projecting toward the rear of the cage are the coin ejecting pins T, T. These may be of any desired form. I preferably turn their rear ends downward.

Secured to the rear end of the upper lever Q in the path of travel of a coin inserted into the apparatus is the upper coin receiver U constructed of a vertically arranged plate having its two sides turned rearward to form flanges or lips U U These flanges are farthest apart at the top of the receiver and gradually approach toward each other as they extend downward so that a coin of a known diameter, for which the receiver is designed, when inserted therein will be caught and held between the fianges and all coins of a lesser diameter will fall through the receiver and not be retained therein. The flanges U U extend rearward along the sides of the boss 25 sufficiently to allow the front of the boss to enter the rear part of the receiver, but not far enough to come in contact with the wall G; the office of the boss 15 is to conduct the coin into the receiver. U is an opening in its front of sufficient size to allowthe coin ejecting pin T to pass when the apparatus is operated.

Q is the weighted front end of the lever Q. When in its normal position it rests below the opening S, in the rear of the butment wall H thereby locking the apparatus and preventing its operation unless the lever is tilted by the proper coin inserted into the coin re- IIS ceivers. The lever is also provided atits front end with the finger Q J is the before mentioned upper sliding carriage. Itis supported by, travels upon and is guided by the rods I, I; at its front end is the shoulders J projecting downward immediately in rear of the upper limb to of the pin M. Its rear end is extended downward and rearward to form the recessed lip J On the top side of the carriage are securely arranged one or more spurs or pins J J J in such manner that their points are elevated above the carriage and project forward.

Arranged on the rear end of the lower le ver R in the path of travel of a coin falling through the coin receiver U is the lower coin X in the lever Q.

receiver V designed to receive and hold a coin of lesser diameter than the coin for which the upper coin receiver U is designed. It is provided with the flanges or lips V V and the opening V and is constructed substantially in form as the receiver U except that it is smaller and that a direct line drawn at any point between the flanges V and V would be less in length than any directli'ne drawn at any point between the flanges U and U of the upper receiver.

R is the weighted front end of the and is provided with the finger R K is the before mentioned lower sliding carriage supported by, traveling upon and guided by the rods 1 I havingat its front end the shoulder K projecting upward immediately in rear of the limb w of the pin M. Itis bent backward to form the arm K which arm extends to the rear of the carriage parallel with and sufficiently apart from the upper side of the carriage to allow the front end of the lever R to travel beneath it when the operating rod L is reciprocated and the lever B is not in operation; on the face or lower side of the carriage K are securely arranged one or more pins or spurs-K K K in such manner that their points drop below the carriage and project forward.

The levers Q and R are connected each to the other at their rear ends by the cord W one end of which is attached to the set screw The other end of the cord is attached to the lever B. Any suitable material of proper form may constitute this con nection. It may be a jointed or rocking rod or a chain. I prefer however to carry out this lever R feature of my invention by means of a flexible silken cord which cord may be adjusted in length by means of the set screw X and thereby the levers Q and R with the coin receivers U and V located and retained in position, and also that when a coin is inserted into and held by the coin receiver V its weight will overbalance the levers Q and R and by means of the cord W tilt conjointly the levers, thus raising the front end Q of the lever Q above the butment wall H and opposite the opening S and unlocking the mechanism and rendering it capable of operation.

The operation of the apparatus isas follows and is best shown in Fig. 6 ;A coin of a known diameter and for which the apparatus is designed, as a five cent nickel coin of the United States is dropped through the coin slot ain the case A. It falls upon the inclined part k of the coin chute down which it slides into and drops through the vertical part l of the coin chute, and is by the boss t guided into the coin receiver U. The coin being of greater diameter than the width of the receiver it is caught and held therein between the flan ges U and U ;the weight of the coin over balances the lever Q to. which the receiver is attached, depressing the receiver end and tilting upward its front end Q above the butment wall H opposite the opening S, thus unlocking the mechanism, and raising the finger Q above the plane of the carriageJ behind the recessed lip J ,power as the hand now applied to the knob P contracting the spring N draws forward the operating rod L the cross head 0 the levers Q R and coin receivers together with the coin held in the receiver U. until the coin is prevented from further advancing by its coming in contact with the rear end" of the coin ejecting pin T. The further withdrawal of the operating rod L causes the receiver to be drawn away from the coin, when the coin drops into the bottom of the case to be removed therefrom at will. WVhen the coin drops out of the receiver the finger Q drops into the recess of the lip J of the carriage J resting upon the lip and preventing the weighted front end of the lever falling farther, and the front end Q is in contact with the rear end of the lip and the pins J J J engage the underside of the lowermost article in the tray C resting on the flanges f. f. Afurther withdrawal of the rod L causes the lever Q retained in the cross head 0 by the pin y to press against and push forward the carriage J, sliding on the rods I, I,

and the spurs J J J push forward guided by the flanges f, f the article to be ejected or withdrawn from the apparatus sufliciently through the opening 9 to permit of the article being grasped and fully withdrawn from the apparatus; the rod L may be withdrawn until the cross head 0 comes in contact with the butment wall H when it is prevented from further withdrawal ;-the power being removed from the knob P the operating rod L with the parts attached thereto is at first sufficiently retracted by the opening of the spring N pressing against the pin M to disengage the finger Q from the lip J and allow the lever Q to drop below the carriage, when the lever is supported by and rides upon the bot tom of the opening. S in the butment wall 11. The upper limb to of thepin M then comes in contact with theshoulder J at the front of the carriage J, the continued opening of the spring pushesbackward the rod L and the parts attached thereto, and the carriage J until the rear end of the carriage comes in contact with the butment wall I-I preventing the further backward movement of the pin M and the rod L, and the front end of the lever. Q having repassed through the opening S it falls by its gravity behind the butment H locking the apparatus and preventing itsfurther operation until another coinis introduced into it; during the. movement above described the free front end of the lever B has remained together with the carriage K inoperative, the lever B having its front end reciprocated by the movement of the rod L between the arm K and the carriage K. When a coin of lesser diameter than that of a coin for which the upper coin receiver is designed, and for which the lower coin receiver V is designed;as the present one cent coin of the United States, is dropped through the coin slot a into the apparatus it travels the path described of the larger coin but being of a lesser diameter than the coin for which the coin receiver U is designed, guided by the boss 25, it falls through the receiver U into the coin receiver V where it is caught and held by and between the flanges V and V The weight of the coin so held depresses the rear end of the lever R and overbalances the front ends of both the levers Q and R tilting upward their front ends, the lever Q being tilted by means of the cord W con-- necting the rear end of the levers, the front end Q of the lever Q is raised upward through the instrumentality of the cord W only a distance sufficient to raise it above the bottom of the opening S to unlock the mechanism and permit it to be operated, while the front end R of the lower lever R is tilted upward above the end of the arm K of the carriage K. Power as the hand now applied to the knob P,contracting the spring N draws forward the operating rod L and the parts attached thereto as also the coin in the coin receiver V until the coin is prevented from further advancing by its contact with the rear end of the coin ejecting pin T. The further withdrawal of the rod L causes the receiver V to be drawn away from the coin held in it, which is forced out of the receiver by the fixed pin T and drops into the bottom of the case; when the coin drops out of the receiver the front end R of the lever R falls until the finger R rests upon the arm K preventing its further fall, and its end R is immediately behind the arm K. The further withdrawal of the rod L causes the leverRto push for ward by means of the arm the carriage K. when the pins or spurs K K K engage the upper-side of the upper most article in the tray D and pushes the article forward through the slot or opening 11. sufficiently to permit of the article being grasped and fully withdrawn from the apparatus. The power being removed from the knob P the operating rod L with the parts attached thereto is at first sufficiently retracted by the opening of the spring N pressing against the pin M to disengage the finger R from the arm K when the end of the lever R falls and the lower limb a: of the the pin M is in contact with the shoulder K at the front of the carriage K. The continued opening of the spring N pushes backward the rod L and the parts attached thereto and the carriage K, until the rear end of the carriage K. comes in contact with the butment wall H preventing the further backward movement of the pin M and the rod L; and the front end of the lever Q having repassed through the opening S, it falls by its weight behind the butment wall. H. locking the apparatus. Durin g this last described operation, the free front end of the lever Q and the carriage J have remained inoperative.

The guiding devices and also the contour of the levers Q, R, and the carriages J, K may be modified within wide limits so long as their construction is such as to permit or insure the requisite movements of the parts with reference to the contents of the trays C and D.

It may be observed, in an apparatus constructed according to my invention any desired number of similar combinations of the upper and lower trays and intermediate mechanism cage may be placed in a suitable case, one series above the other and all operated by coins of varying diameter introduced into the case through a single coin slot when the interior diameters of their coin receivers is graded downward, the interior diameter of each receiver between its flanges being greater than that of the receiver immediately below it.

I am aware that prior to myinvention vending machines have been made with carriages capable of being reciprocated and provided with pins or spurs; I therefore do not claim such a combination broadly but WVhat I do claim, and desire to secure by Letters Patent, is-
