VENDING APPARATUS Filed May 21, 1931 2 Sheets-Sheet l Patented May 23, 1933 P E'r WILLIAM K. SGHAUWEKER, F CLEVELAND, OI-IIO VENDING ArPABA'rUs Application filed May 21, 1931. Serial No. 539,035.

This invention relates to a vending apparatus of the type wherein the'operating mechanism must be released or operated by means of a suitably shaped tolcen or check, coin, or other device.

The majority of vending apparatus of this character are usually operated by the insertion of a coin of certain denomination, or bv a tolten or check of certain size and configuration. However, considerable di'fficulty has been enperienced'in the use of vending apparatus of this character, since it has been possible to release or actuate the opcrating mechanism of such apparatus by means of slugs, foreign coins of lessvalue than the coin intended to be used in the mach-ine and other devices.

The principal object of the present invention is to provide a vending apparatus that so constructed that the means for actuat ing the same cannot be easily and profitably imitated, with the result that likelihood of the apparatus being dishonestly operated 1s reduced to minimum.

para-tus which is eflicient in operation, and composed of a relatively few number of parts, so arranged that there is small chance of the apparatus becoming inoperative. Additional objects and advantages will become apparent hereinafter.

An embodiment of the invention is illustrated in the accompanying drawings, wherein,

The apparatus comprises a base portion 10, within which is arranged part of the actuating mechanism,'and a magazine portion 11 containing the-articles to be vended, and provided with a suitable opening to enable the customer to remove the article that has been purchased. The magazine 11 is, of course, enclosed in a suitable glass or other transparent enclosure 12-, the latter having an opening, as indicated at-13 in Fig. 3. It should be understood that the maga zine 11 is only partially shown in the drawings, and that the same may extend to any suitable height. A member 14 is secured to the front of the base 10 adjacent one end thereof, for the purpose of receiving the device that effects the release or actuation of the mechanism, which, in turn, causes the article to be deposited opposite the opening in the magazine and in the glass casing.

In order to eliminate to a large degreethe unlawful operation of the apparatus, it is proposed to construct the same to receive a cartridge, indicated at 15 in Figs. 4 and 5, filled with a suitable gas, such as carbon dioxide. The member 14 is shaped to receive this cartridge 15, such cartridge being provided with a reduced internally threaded end 16, within which isarranged a valve'insides 17 When the cartridge is inserted in themember 14, with the reduced end 00- incident with the reduced portion 17a of the passageway 18in the member'li, the cartrid'ge will roll down through the member 14 until it is stopped and properly positioned or straightened by a gate 18a, closing an opening 19 in the front wall of the base 10, which opening is arranged in communica- 9 tion with the passageway 18 through the member 14. The gate 18a is pivotedat 20, and has an extension 21 extending toward the left'of the base, as viewed in Fig, 4,;such extension lying in the path ofan arm22, carried at the inner end of a push rod 23 extending through a member 24 secured upon the outside of the base. This push rod 23 is provided with a handle 25 at itsouter end, A and is normally maintained in its outward ner end a swinging plate 29 normally .held

in position by a spring 30, to hold the cartridge upon the inner end of the apron 27. A U-shaped bracket 31 is secured upon theinside of the base to theleft of the pair of brackets 28, as viewed in Fig. 5, the arms of such U-shaped bracket :31 slidably supporting a rod'32. Connected to this rod is into the bushing 42.

a link member 33, the connection between the rod and link member being so arranged as to provide a lost motion and including a slot 34 in the link member through which extends a pin'35 carried by the rod. The

link member 33 has an offset semicircular end 36, which is pivotally connected at 37 to a crank arm 38 fixed upon a shaft 39 extending transversely through the base of the apparatus and carrying on one of its ends a lever 40 arranged externally of the base. When the lever 40 is moved to the right, as viewed in'Fig. 3, the crank arm 38 is rotated to the right, as viewed in Fig. 4, the

link 33 being likewise moved to the right, which movement of the link, as soon as the pin 35'engages the end-of the slot 34, will cause the rod 32 to move to the right into engagement with the end of the cartridge 15 to push the latter toward the cylinder fitting 41, arranged upon theinside of the right hand end wall of the base, as viewed in Fig. 4. This fitting is provided with a horizontally extending opening, within which is arranged a suitable bushing 42, and which hasits outer end restricted by a packing 43, having a'central opening through which extends the reduced end of a pin 44.

When the rod 32 has moved the cartridge sufficiently toward the fitting 41, the reduced end 16 ofthe cartridge engages the packing 43, while the reducedend of the pin44 depresses the valve pinofthe valve insides'17, andthus unseats the valve to allow the gas within the cartridge to pass The right hand end of the rod 32, as viewed in- Fi 4, is provided with an upstanding bracket 45, having a bifurcated upper end, between the arms of which a piv- A spring 47 is located between the underside of'the dog and the upper side of the rod 32, to normally swing the dog in a clockwise direction, while the'right hand end of the dog, as viewed in Fig. 4, is provided with a hook 48, tapered so as to have two cam surfaces 49 and 50. When the rod 32 is moved to the right, the hook 48 passes into a bayonet slot 51, formed in the plate 29, the cam surface 50 riding upon a curved edge 52 of the slot, until the hook is in line with the offset portion of the slot, whereupon the spring 47 swings the dog to move the hook into holding engagement with the plate. When the rod 32 moves in the reverse direction the shape of the cam surface 49 of the hook is such that the plate 29, is swung outwardly against the tension of the spring 30, thereby allowing the cartridge to roll off the apron 27 and into the base of the apparatus.

The fitting 41 is provided with a recess extending vertically into the fitting, and communicating with the interior of the bushing 42 by means of a' reducedopening 53 formed therein. The recess is threaded to receive a cylindrical fitting 54 passing through the top of the base and screwed into the recess and forming a cylinder. A piston 55 is arranged in the fitting 54, andhas its lower end provided with packing, providing a relatively tight fit between such end of the piston and the walls of'the fitting, this packed end of the piston normally lying over the opening 53 in the bushing '42.

'It is clear that when the cartridge has been moved into engagement with the packing 43 and the valve within the cartridge unseated,that the confined gas willenter the bushing 42 and cause the piston 55 to be moved upwardly within the fitting 54. The fitting 54 is provided, adjacent its outer end, with aligned slots 56, in order to permit an arm 57 arranged in the fitting with its lower end engaging the upper end of the piston, to have slight lateral movement, the purpose of which will be readily apparenthereinafter. r

The arm 57 is pivotally connected at its outer end to the end of a bell crank 58, fixedly associated with a shaft 59 extending across the end of the magazine and rotatably mounted in brackets 60, secured upon the end wall of the magazine. This wall of the magazine is provided with openings 61, through which project arms 62 carried by the shaft 59, such arms 62 being normally maintained. in the horizontal position by means of a spring 63, secured at one of its ends to thetop .of the base and at its other end to a portion 64, formed on-the shaft 59.

The end of the shaft 59, adjacent the rear of the apparatus, has fixed thereto an arm 65 extending partly across the rear of the magazine, and pivotally connected at its end to one end of a link 66, the other end of such link being pivotally connected to an arm 67 in turn carried by a shaft 68' extending across the other side of the magazine and rotatably supported iii/brackets 69 secured to the wall of such side.

.Itshould be noted that the shaft 68 is in the same horizontal plane with the shaft 59, and is provided with arms 70, extending through openings in the side wall of the magazine, corresponding to the openings 61 and aligning with the arms 62, so that the rms 62 and 7 0 form a support for an article 7 1.

From the foregoing it will be seen that when the car tridge 15 is moved into engagement with the packing 43 and the gas released from such cartridge, that the pressure of the gas will cause the piston 55 to move upwardly, and in turn, will move the'arni 57, thereby rocking the shaft 59 against the tension of the spring 63, and through'the operating connections just described the shaft 68, thus causing the arms 62 and to move downwardly to allow the article 71 supported thereby, to drop into the lower part of the magazine opposite the openings formed therein.

Having thus described the manner in wl ich an article may be obtained upon placing the proper cartridge in the apparatus, I will now proceed to point out the mechanism whereby the articles may be successively moved into position upon the supporting arms 62 and 70.

The lefthand end of the shaft 39, as

73 is pivotally and eccentrically connected at 7st. A spring 75, arranged within the base of the apparatus, is also connected to the disc 72 and to the rear wall of the base, the purpose of such. spring being to maintain the shaft 39 in its normal position. The link 7 3 extends upwardly through the top of the base and has its upper end passing through a member 76, secured upon the rear wall of the magazine. This member 76 is provided with what may be termed an eye portion 77, having an inclined wall cooperating with a similarly formed edge 78 of the link 73, whereby, when the disc 72 rotates in the proper direction to move the link '73 upwardly, the lower end of such link will also be moved laterally, while the upper end will rock upon the inclined wall and thus cause the hook 79, arranged at the up 1e1- end of the link 73, to engage an arm 80 associated with a shaft 81 rotatahly supported in brackets 82, secured upon the side wall of the magazine. The shaft 81 is provided with an arm 83, pivotally connected at its outer end to one end of a link 84, the opposite end of such link being pivotally connected to an arm 85 associated with a shaft 86, extending transversely of the opposite side wall of the magazine, and r0- tatably supported thereon in brackets 87.

The shafts 81 and 86 are in the same horizontal plane, and are each provided with downwardly extending hook members 88, the

from the hooks. A spring 91 is connected I to the link 73, adjacent the lower end thereof and to the top of the base 10, in order to facilitate the disengagement of the hook 79 of the link 73 from the arm 80.

WV-hen the cartridge is deposited in the v I.

apparatus and moved in upon the apron 27, the lever 40 is swung to the right, as viewed in Fig. 3, until it abuts a stop pin 92, such movement of the lever causing the rod 32 to push the cartridge into position for the I gas to be released therefrom, and also causing rotation of the disc 72, so as to move the link 7 3 upwardly and laterally until the hook 79 thereof is in engagement with the arm 80. The release of the gas in the cartridge moves the piston 55 upwardly, and in turn, the arm 57, to swing the arms 62 and 70 downwardly to release the article 71.

After the article has dropped from the arms 62 and 70 the lever 40 is released, whereupon the spring 63 returns the arms 62 and 70 to their horizontal ositionand the spring 75 returnsthe disc 2 and shaft 39 to normal position, at which time the lever 40 is in engagement wi h the stop pin 93. I

This return movement of the disc 72 pulls the link 73 downwardly, and the hook 79 of the link being inengagement with the arm 80, the shafts 81 and 86 are rotated to cause the hooks 88 to move outwardly and to allow .an article 71 to fall upon the arms 62 and 70,

at which time the apparatus is in condition to be used by another customer.
