To all whom it may concern. I I e Mk'onron -HOFHEIMER a citizen of the United States, and a resident of Baltimore, State of Maryland, have in-; vent-ed certain new and useful Improve- Be it known that T,

ments in Coin-Operated Ven'ding-h Iachines, of which the following is a specification.

This invention relates to coin-operated he invention consists ofvending machines. various features hereinafter more particularly set forth By means of said invention described and may be made at comparatively small cost and which is adapted to be attached to the backs of seats for use in places of public assemblage. Certain features of the invention relate to an arrangement whereby one ejector operates in connection with two magazines for the packages, whereby compactness is secured; Another feature relates to simple and efficient means for closing the coin slot or coin chute when the last package in a magazine is ejected therefrom. Other features of the invention will appear from the following description and claims.

In the accompany ng drawings formlng part of this specificationand in which like reference numerals designate corresponding parts, 7

Fig. 2 is a rear elevation of the machine; Fi 3 1s a sectlonal plan view on the line 3 I? of Fig. 1;

Fig. 4 is a front elevation with the front section of the casing removed and showing the back plate and the parts carried thereby;

Fig. 5 is a sectional elevation on the line of Fig. 1;

Fig. (3 is an interior elevation showing the coin detector andjclosure for the coin chute carried by the front plate;

Fi 7 is a front elevation )artl in sec in the claims. it'is sought to} provide a small compact inachine which shall be simple and efficient and one which plate of the casing and constituting one section thereof. 2 is the front plate of the easing having the side walls 3 and 4t and top wall 5 formed integral therewith. The part 1 may conveniently be referred to as the fiat section of the casing, while the section composed of the parts 2, 3, 4c 'and 5 may be called the box-likesection of the casing. 6 and 7 are two upright magazines arranged side by side or' abreastof each other. These maga- Zines are formed of sheet metal, are open at their tops and may be soldered or riveted to the face of the back plate 1. The magazine 6 is provided at its lower end. with frontand back rails 8 and 9 designed to support a stack of packages. The magazine 7 is provided with two similar rails 10 and 11. These magazines are separated a short distance from each other so as to provide at their lower ends a path for the coin, as will hereafter appear. Bridging this space and secured to the front faces of the magazines is' a guide 12 to direct the coin into said space. 13 is an ejectorbar for ejecting packages from the magazines. In the present form of the invention this ejector consists of a reciprocating bar or plate, provided with two sets of teeth 14 and 15. Between these sets of teeth is formed in the bar a recess 16 and at the ends of the teeth are formed smaller recesses 17 and 18. 19 is a dog carried on a stud 20 projecting centrally from the back plateand provided with a coiled spring 21 to' hold the dog in upright normal position, as shown in the drawings, with its point in the middle of recess 16. Secured to the front face of the ejector bar 13 is a coincarrier 22 providing a slot 23 to receive a coin. The outer end of this carrier is provided with a projection 2st. Directly beneath this carrier extends a plate 25 which is cut out of the back plate 1 and extends forward in a horizontal position, thus leaving an opening 26 in the back plate; The rear face of the ejector bar-13 is provided withastop pin 27 which contacts with the end walls of the opening 26 to limit the movement of the ejector bar 13 in either direction. The plate 25 constitutes a rail on which the coin is supported with its upper edge in line with the inner end of one of the packages, as shown in Figs. 5 and 7. The plate 25 extends over the top of the coin receptacle 28 and terminates a short distance from the side walls of the coin receptacle so as to provide inlet openin 29 and 30 thereto for the coins. The coin receptacle is secured to the face of the back plate 1 and is heart-shape in general contour. The front face of the coin receptacle is provided with two wings 81 and 32 whose upper ends provide supports for a rod 33. Centrally located on this rod is a fixed stop 34. 37 and 38 are retractile springs surrounding the rod 33 and operating to hold the collars 35 and 36 respectively against stop 34. Be tween these collars stands the projection 24 of the carrier 22.

The lower ends of the side walls 3 and 4 inclose the sides and bottom of the coin receptacle 28 and so as to provide delivery chutes 39 and 40 on either side of the coin receptacle for the delivery of packages by the ejector. The back plate 1 has a lower extension 42 which is bent forward to form a horizontal shelf 41 which stands a short distance below the casing and directly be neath the opening 43 of the front section of the casing. When a package is discharged from its magazine, it passes beyond the side walls of the coin receptacle and into one of the delivery chutes 39 or 40 and passes out through the opening 43 on to the shelf 41 from which it may be removed by the hand of the patron.

The operation of the parts above described is as follows :'lVhen a coin is received by the guide 12, it enters the space between the magazines and drops into the slot 23 of the carrier 22, and is supported in this slot by the rail 25. The ejector bar 13 is then pulled outward in either direction, the coin moving over the rail 25 until it passes beyond the rail 25 and drops out of the carrier through the inlet opening 29 or 30 into the coin receptacle 28. In the movement of the coin, it engages the lower package in the magazine and pushes it off its supporting rails, the package falling beyond the coin receptacle down one of the delivery chutes 39 or 40 on to the plate 41. In the movement of the ejector bar 13, the teeth wipe over the end of the pawl 19. For example, suppose the extractor bar 13 is pulled to the left, referring to Fig. 4. In this case, the teeth 15 wipe over the pawl and tilt it to the left until the pawl enters the recess 18 at the end of the bars movement. The pawl then moves to upright position by reason of its spring. When the ejector is released its spring 87 returns the ejector and the coin carrier to normal position by the pressure of the collar 35 against the projection 24 of the carrier. In this return movement, the teeth 15 wipe over the pawl 19 tilting the pawl to the right until it comes to rest in its upright position in the recess 16.

If the movement of the extractor bar to the left, as above described, is arrested be same way. Thus, by means of the pawl and teeth, the operator is insured of the delivery of one package and partial or uncompleted movements of the extractor bar to secure unauthorized delivery of a package is prevented.

The magazine 6 is shown as containing a column of chocolate packages 44 and magazine 7 is shown as containing a column of chewing gum packages 45. Resting on top of the packages in magazine 6 is a block 46 having a forwardly projecting lug 47, and resting on the packages in magazine 7 is a block 48. 49 is a lever working on the pivot pin 50 secured to the front plate 2. The upper end of this lever 49 is bent over to form a lip constituting a closure 51 adapted to close the coin slot 52 formed in the top wall 5 of the casing. The lower end of the lever is bent back to form a cam 53. In the normal position of the lever the closure 51 is out of register with the coin slot and the cam 53 is in line with the lug 47, as shown in Fig. 1. When the last chocolate package has been ejected from its magazine, the lug 47 engages the cam 53 so as to throw the lever over and cause the closure 51 to register with the coin slot 52. This prevents the depositing of a coin after the chocolate packages have been exhausted. When the last package in magazine 7 has been ejected, block 48 comes to rest upon the rails 10 and 11 and if a coin is thereafter dropped into the machine, block 48 bars the movement of the coin and its carrier to the left although the ejector may carry the coin to the right for ejecting a package in magazine 7, if the packages therein have not been exhausted. ()f course, the blocks 46 and 47 are interchangeable. by the arrangement of the blocks and lever that if the coin slot is open and a. coin is inserted therein, the machine may be operated to extract a package and the patron may be sure that he will not lose his coin.

54 is a magnet secured to the front plate 1 by stud 55. The upper side of the magnet is'inclined so that a coin passing through the coin slot will fall upon and run down the upper side of the magnet. 56 is a guide pin on the front plate 2 which insures the passage of the coin along the magnet. The

' momentum of the coin traveling. over the magnet is such as to cause it to jump over the guide pin 57 secured to the front plate 2 and against the side wall 3. It then falls upon the inwardly projecting and inclined flange 58 which lies against the front wall 2. This flange 58 is carried by the lower end of the gate 59 consisting of a sheet metal plate carried on the rod 60. The rod 60 extends across the inner side of the front plate 2 and is supported by the side walls 3 and l. The gate 59 is arranged to slide on this rod and is also capableof swinging thereon to and from the plate 2. It is provided at its upper end with the flange 61 projecting toward the plate 2 and extending directly underneath one end of the coin slot 52. It is held in normal position by a spring 63. The sliding movement of the gate 59 is limited by the side wall 3 and the pin 64 extending downwardly from the top wall 5. 65 is a guide wing carried by the gate to prevent the coin from falling laterally oil the magnet. Secured to the front plate 2 is an L shaped rail 66 which is the proper distance from and parallel with the flange 58. The distance of the rail from theflange is such that a proper coin of a proper diameter, such as an unmutilated penny 67, when moving down over the flange 58, will slightly overlap the rail 66, as shown in Fig. 1. The rail 66 is provided with a guide wing 68 projecting at an inclination from the plate 2. Rail 66 is also provided with a right angled flange 69 which terminates at one end in a cam 70. The space between the lower edge of the rail 66 and the flange 58 is of suflicient size to receive a slug or disk of a scant diameter or slightly less than that of a proper coin. This space forms a pocket which constitutes a trap for such a scant sized disk and, of course, is in communication with the coin chute. The coin chute extends from the coin slot between the front plate 2 and wing 65 along over the magnet, thence betweenthe gate 59 and plate 2, over the pin 57 to the wall 3, turning thence along the flange 58 and overlapping the lower edge of the rail 66, thence against the guide wing 68 through the guide 12 and to the coin carrier 22. The coin chute, as thus described, overlaps the lower edge of the rail 66 and communicating with this portion of the coin chute is the pocket for trapping a slug, said pocket lying between flange 58 and the lower edge of rail 66 but not overlapping this rail. The slug of scant diameter cannot pass out of this pocket to ward the guide wing 68 because of the down ward turn of the rail 66 which blocks its passage.

The gate 59 carries a lip 71 arranged to coiiperate with the cam 70. When a coin ispushed into the coin slot 52, it engages flange 61 of gate 59 and thrusts the gate to one side and in'opposition to its spring 63. As the gate moves laterally, its lip 71 moves over the cam/ of flange69, thus moving the gate away from plate 2. If a slug has been trapped in the pocket the movement of the gate by the insertion of a coin opens the pocket and permits the slug to drop down into the coin receptacle but without passing into the coin receiver 22.

The inner edge of the flange 58 is cut away along its inner portion to form a slot 72 narrower than the thickness of a proper coin butsufflcient' to receive a disk of scant thickness. Thus, when a slug consisting of a disk of scant thickness is deposited in the machine, it passes out of the coin chute through this slot 72. Or if it is trapped in the pocket, above described, with its lower edge projecting part way through this slot 72, it will escape when the next coin moves back the gate 59.

If an iron or other magnetizable disk is inserted in the coin slot, it will be deflected by the magnet so as to roll into a by-path along the flange 69 of rail 66, whence it passes between the front plate and lip 68, dropping into the coin receptacle at one side of the carrier 22. Y

7 3 and 7 4 are lips struck up from the sheet metal back plate 1. The lower ends of the magazines may be soldered to these lips, the lips providing a slide way for the ejector bar 13 beneath them and between the back plate and the magazines. 75 and 79 are U- shaped lips on the back plate which engage two lugs like 76 on the side walls 3 and 4:, respectively. 77 is a lug secured to the back plate 1 and arranged to enter a slot in the top wall 5 and be there held by a lock 7 8.

It will be seen that the side walls of the coin receptacle curve outwardly and are surrounded by the outer side walls of the package delivery chutes, these latter converging at their lower ends to a common exit opening and being open at theirupper ends to receive packages ejected from the magazines. The tortuous direction of each delivery chute prevents tampering .Wlth the machine by means of a wire or prod inserted through the delivery or exit opening.

While the preferred embodiment of the various features of the invention is shown in the drawings, it will be understood that many of these features may be variously modified and that various ones ofthem may be used in other relations without,- departing from the spirit or scope of the invention.
