Application tiled May 12, 1910. Serial No. 560,767.

To all whom it may concern:

Be it known that I, FRED I. J UDsoN, residcounty of Nance vand State of Nebraska, have invented certain new and useful Improvements in Vending- Machines, of which the following is a specification.

My invention is a machine for vending peanuts or the like in sacks, and it primarily has for its object to provide a machine for the purpose stated wherein there will be only one major moving part that simultaneously discharges the releasing coin and the vended package, and in which means are provided for keeping the contents of the machine warm.

Briefiy stated the invention provides a machine that is very simple and positive in its action.

Peanuts when placed in small sacks make a very irregularly shaped package and are hard to control in their passage through a vending machine. I have therefore protension springs in the magazines that enga e the sacks in a manner that will 'enable t em to be controlled in their passage through the machine to prevent c o ging or premature discharge from the mae me. A lever is formed with the coin chutes, of which there are two, and this front of themaclnne. It is locked in its different positions by pawls which are released by the coin that permit the lever to be moved from one position to another. The lever has a pusher block so that when itis moved from one position to another it will push a sack off of the rest table into the discharge passage vof the machine to ei'ect the sale.

'lhe invention includes a special construction of article magazine and a heater therefor and it further includes certain devices to protect against the use of spurious coins and also attempts to rob the machine through the article outlet.

a knob exposed at the' tral, vertical, cross section on the line 3 3 of Fig. '2, looking in thedirection of the arrow." Fi section on t e line 3--3 of Fig. 2, looking in the opposite direction to the,arrow. Fig. 5, is an enlarged detail vertical, longitudinal section of the lever and its locking device. Fig. 6, is an enlarged detail, sectional view of the u per end of the lever and the coin slot of the casing. Fig. 7, is a detail, perspective view of the article table the lam carrier and the heater partition. Fig. 8, 1s a detail view of the coin slot closer. Fig. 9, is a detail elevation of the coin detector device and its contents. h

Referring nowl to the aecompanyin drawings in which like letters and numera s indicate like parts in all of the figures, 1 designates the front o'f the casing which has doors 23-24'in its back and a com slot or opening A in its front.

2 designates the bed plate that supports the coin detector mechanism and is covered by a removable cover plate 3, as shown.

A casting 4 is secured on the Vfront of the machine' to hold the pivot 8 on which the combined coin chute and pusher lever is 4, is a central, vertical, cross mounted. The coin chute and pusher lever 9 forms one of the essential features of my invention. The lever 9 is oscillated for a purpose hereinafter to aplpear, by a knob 6 that projects through a s ot 5 in the front wall of the machine, the slot being guarded by a plate 5. Thelever 9 which is best shown in Figs. 5 and 6 comprises a flat body having two parallel coin chutes 9b--9 runnlng from end to end, the entrance to such chutes 9"--9c bein enlarged as at 9", while the lower or exit ends thereof diverge as at 9. The lever 9 has two' sets of ratchet teeth 9e-9' to coperate with the respective pawls 10-10n that are pivoted at 10"-10c and have weighted ends 10d- 10 to hold them 1n their ratchet teeth engaging positions. Stops- 11-11 are provided to limit the movement of the pawls 10--10l when under the influence of a'coin. The upper end of the lever 9 is bent over at 9x to enter a channel way 1x in the casing wall to insure the proper entry of the coin into the chute. The lever 9 carries the pusher block 12 which is secured to the rear side of the lever 9 near its lowerlend.

Within the casing 1 is a receptacle 15 containing a heater 16 of any approved type and having a flat top to form tables 153-13.

above the tables 13 to permit movement of the pusher 12. A'heat delecting table 17 is held within the tube 14 to distribute the heat, as will be clearly understood by referksame in any suitable manner.

ence to the drawings. A

A coin box 16 is supported on cleats 31-32 and a receptacle 15 is held above the Suitable air inlets 15x are provided for the receptacle 15 and a door 15y may be also provided therefor to permit of conveniently entering and removing the heater- 16.

In order to hold the sacks on thev table 13, tension springs 17-172L are provided and the springs prevent the premature moving of the sacks from the tables. Trap doors 19-19a of L-shape in side 4elevation are hinged at 21.-21a and have counter weights 20-20a to prevent any one reaching up through the discharge outlet 18 and' removing the sacks G or H from the respective tables 13.

The coin detector mechanism is best shown in Fig. 9 of the drawings, by reference to which it will be `noticed the plate 2 has a coin entering pocket 2a which merges with and delivers the coin into a runway portion 2" that in turn merges with another runway portion 2C having a movable bottom formed by a balanced lever D that is pivoted at. E and has a long arm D along which the coin travels toward the discarding chute 2d if it be too light in weight. A coin ofthe proper weight, however, will overbalance 'the Weight of the lever D and passageway 2e that leads to the slot A in the casing of the machine.

Asample holder 7 is provided on the face of the machine in which a sample of the goods the machine is designed to vend, may be exposed to the view of the purchaser.

In operation, assume the mechanism to be filled with sacks of peanuts ortho like (the mechanism being filled through the back door 24) and the lamp orvheater 16 burin ing; the sacksr on the table 13 being exposed to the hottest part of the receptacle 15 will be kept warm thereby whilethose above in the magazines are heated to a lesser degree by the passage of' the heated air and gases through the tube 14. The operator next places a proper coin in the pocket'21 whereupon it gravitates downwardly into the pas-` sageway 2e and through the slot A into that one of the .lever chutes B-B whose entrance is in alinement therewith. The coin passes down thechute B or B', as the case may be, and rests on the corresponding pawl 10--10a to move it from engagement with the ratchet teeth on the lever 9 whereupon the operator may move the lever to drop into the cause the pusher 12to push a sack off the table 13 which thereupon drops onto and passes by the trap door 21--21a as the ease may be and falls into the discharge hopper from whence it may be removed through the opening 18 in the front of the casing. As the lever 9 is moved from one position to another the coin will be carried along the respective pawl until it drops between the pawls into the coin box 22, it being understood that the stops 11-11a prevent the discharge of the coin until the lever 9 has been pushed over.

In order, when an article chute becomes empty, that the operation of the machine may be stopped, I provide a coin chute closer mechanism which is composed of a lever 25 pivoted at 26 and having its short arm 28 bent over to form a pin 29 that p'rojects through a hole in the front wall of the casing and in the plate 2 to prevent a coin dropping from the pocket 2a into the passage 2", the plate 2 having an opening 30 to permit the pin-portion 29 to project therethro-ugh. The long arm of the lever 25 projects down to the bottom sack in the chute and a spring 27 is provided which continuously tends to move the lever in a position to project the pin 29 into the path of a coin, it? being understood that so long as the article magazines contain a package the pin 29 will be withheld fromv the path of the coin, as will be clearly understood by refe-renee to Figs. 6 and S of the drawings. It should be understood that there is one coin Kchute closer for each magazine.

Ifrom the foregoing it will be seen that by my construction of machine a sack which is next to be delivered is always kept the hote test by virtue of its resting on the table or platform 13, While the remaining sacks 4are kept Warm by the hot air Hue or tube- 14, as before described.'

The tension springs 17-17a I consider an important improvement in machines of this type las peanuts in small sacks make a very irregularly shaped package and it has always been a hard matter to control them in a vending machine and insure certain delivery without tearing the sacks or clogging 'the machine. By using the springs 1T-1'f, the sacks will reach the platform 13 in the correct position. Then the lever 9 is in one position one column of sacks is resting on the pusher block pushed to the opposite side is releasedbut the edge of the bottom sack rests on the edge of the block 12 until its block is clear out of the chamber. If the springs 17-17a were not in place the bottom sack would have a tendency to tip down edgewise, that is the outer edge would -tip down before the inner edge was released from the block 12. The springs 17--17 hold the sack level and prevent 1t from falling off the platforms until 12, which-When the lever is the sacks are pushed off. lhen the sacks are pushed o the platform 13 they drop down to the bottom and are taken out through the opening 18, as before mentioned.

Should it beattempted to remove the contents of the inachine'through the opening 18 by reaching the arin therein and attempting to take t-he sacks olf the respective tables 13, it will be observed that weighted doors 19--19EL will be encountered and if the lower plate of such door is held down, then that one which is normally held vertical will assume lthe horizontal position and vice versa, so as to always keep the passage closed against some one who may attempt to rob the machine.

From the foregoing description taken in connection with the accompanying d 'awiiigs it is thought the complete construction, operation and many advantages of my invention will be readily understood by those skilled in the art to which the invention appertains.
