UNITED STATES PATENT OFFECE GEORGE .ivronnrsolv, or iOUGnnEEPSIE, NEW YORK I V I I VENDING MACHINE Application filedhiigust 14, 1930, Serial No. 475,169.

This invention relates to a, Vending ma} as this 1S 2% matter Of detail 1101] iIIVOlVGCl 111 chine for dispensing articles, one at a time the invention and which will have to be and is controlled. by novel'inechanism which p d o s lt local conditions, and also it is released by the insertion of the 'proper coin y be Stated that a number of themilchines 5 which allows one article to be ejected "for each E y be mountedt g in a g 155 @0111 in rt d, caslng if desired.

The object ofthe invention is to provide the d i e as here shown; there s P a novel brake or cushion whereby the con- Vldedv m s P a 10 be veyor on whichis mounted the supports for cured Wlthln a 9 m a to thlsiplate are 10 the articles to be vended, is prevented from m' two 2 2 uplflghts l y the a g 60 a too fast movement after being released.

The forward end of the rod 29 is provided with a collar and a portion 36 which is mounted Within a finger plunger 37 containing a spring so that said plunger 37 may first be moved inward for a short distance without contacting with the collar 35 by which it moves the rod 29. i

A coin controlled lock is provided for this rod, which comprises a coin runway 38 hav ing a coin inserting slot 39; while the rear side of the plunger 37 is cutawayto receive the coin 40 which rests upon a stop 41 secured to the plate 23.

Above the plunger 27 and pivoted to the plate 23 is a latch 42 having a hooked end 43 adapted to engage a notch 44 formed in the rod 29 for locking the same against movement.

Said latch 42 is normally held in a locked position by the spring 45, and is raised to release said rod 29 by the action of the coin 40 which engages with a pin 46 projecting from the rear side of said latch 42, the pin riding up over the coin; the cut-out portion 47 of the plunger 37 pushing the coin 40 against said pin 46 as the plunger is forced inward by the operator; while alter the coin 40 has traveled past the stop 41 it.will drop from p the plunger into a chute which will stack it in the coin box.

The stacking of the coins 40 is accomplished (see Figures 7 and 8) in thefollowing manner.

Below the plate 23 and within the casing is mounted a coin box comprising a box 50 having a chute 51 within which the coin drops from the plunger 37 and runs down an incline 52 striking a stop 53 and falling .on its side in a pile in the holder 54; said coin box being closed by a door 55 having a window 56 and a lock 57 Should it be desired to arrange the lock to be operated by a number of coins, this is accomplished by allowing the first coins to pass through the cut-out and stack up against a stop, while the last or upper coin will register with the cut-out portion and act as the wedge to raise the latch.

The article supports 18 may be formed with .a number of fingers 58 which as the support descends will pass through a stripper or delivery table 59 mounted in the casing.

For preventing the too rapid rotation of the sprockets 15 and a quick descent of the suports 18 I have provided a brake or cushion device, comprising a cylinder 60 closed on its lower end and pivoted to the plate 23 so that it may swing up and down; and this cylinder 60 is provided with a head 61 having a suitable stufiing box through which is reciprocated a stem 62 which has its outer end pivoted to the disk 24 as at 63, while'its inner end is provided with a piston 64 slidably mounted within the cylinder 60 and provided with a small hole 65 through which a liquid such as oil may pass; and it will thus be seen that as the disk 24 rotates, all of the oil in said cylinder 60 will have to pass from one end to the other through the small hole 65 in the piston, thus retarding the quick rotation of said disk 24 and providing a slow movement to the conveyor 16.

I For preventing the operation of the device through the insertion of small coins, slugs, etc. the plate 23 right back oi the cutout portion in the plunger is provided with an opening slightly smaller than the required coin, so that all small coins will drop therethrough and not stay in the plunger.

Having thus described my invention, what I claim as new and desire'to secure by Letters Patent, is-

A vending machine comprising a pair of uprights spaced apart "in parallel relation, a

lower transverse shaft journaled in said uprights near their lower ends, an upper transverse shaft adjustably mounted in said up rights near their upper ends, sprocket wheels mounted upon said shafts, endless conveyors carried by said sprocket wheels, article supports pivoted to said conveyors and adapted to support articles upon them during their downward travel as actuated by the weight of the, articles, an escap-ement wheel secured on the lower shaft, an esc'apement lever coactmg therewith, a cushion device for preventingthe too rapid travel of said conveyor,

comprising a cylinder pivoted adjacent said escapement wheel, a piston mounted therein and a'connecting rod secured to said piston and pivoted to said escapeinent wheel.

In testimony whereof I atfix my signature. GEORGE MORRISON.
