Application July 19,

1 Claim.

This `invention relates to vending machines of that class which isshown and described in Patents Nos. 1,806,814of- May 26, 1931-; 1,827,900 of Oct; 20, 1931; 1,864,847 of June 28, 1932 and 1,876,510 of Sept. 6, 1932, all of which were issued to me forA vending machines and their parts, and the present invention relates more particularly to means for detecting the presence of slugs and counterfeit coins by exposing the same to the viewof the-purchaser as well as to the next customer and the public, so that in this way should aperson operate the machine with either a. slug or counterfeit piece of money it will be placed on public view at once and will remain in `view until the next-purchase is made.

In this manner the use of slugs and counterfeits will be discouraged and detected at once.

The object' of the present invention is to provide means whereby the coins as soo-n as they have eifected the tripping `of the operating mechanism to `.allow the delivery to take place, will be exposed to view of the public.

Another object'` of the invention is to provide asimple, durable and foolproof machine, containing fewV parts and. cheap to construct.

With these and other` objects in view, my invention consists in certain'novel construction and combination oiparts that will hereinafterbe fully describedand claimed, and further illustrated in the accompanying drawings which` form a part hereof and in which like gures of reference referto correspondingpartsfin all of the Views, and

itisunderstoodthat-slight changes may be made `without departingffromthe spirit of the invention.

Figure 1 shows the front elevation of a. vending machine showing my invention, but without the manually operated drive for the conveyor.

Figure 2 is a vertical sectional view of the same, but without the detailed lock and lock operating mechanism, as any of the styles shown and-described in my above referred to patents may be employed.

Figure 3 shows a sectional view, taken on the line 3--3 of Figure 1, showing the coin exposing device. I

Figure 4 is a sectional View taken on the line 4--4 of Figure 2, to illustrate the coin exposing device.

Figure 5 is an enlarged sectional view of a portion of `the machine showing the application of the manually operated conveyor device.

Figure 6 is a partial cross sectional view of the manually operated conveyor device.

Poughkeepsie, N. Y.

1935,` Serialy No. 32,247

Referring to the drawings: As many of the parts shown are the same as those which were described in my- Patent Number 1,876,510 I have for the sake of clearness and comparison, given themthe same reference numbers as those used in the above patent, in which I show a frame composed of a base III towhich are secured the two uprights I I within which are rotatably mountedthe transverse shafts I3 and Ill, which carrythe conveyorv combination sprocket and gear wheels I5 for the conveyor chain I6, to which are attached the article supports I8 having the arms I9.

Upon thefront or downward travelingpart of the conveyor I6 these supports I8 are heldinahorizontal positionby the arms lcontacting with the chain I6, and upon the rear or upward travel of the conve-yor, these supports are folded against the chain outl of the way, themachine being loaded from the front and no articles being supported upon the rear of the conveyor, and the length of chain beinggoverned by thesizfe and number of articles `that'the machine is to hold when loaded.` The articles are placed upon the supportsV I8, andasthe conveyor travels downward are deposted one by'one upon the slotted shelf 59 bysthe flngersof the supports I8 in such a mannerthat they maybe removed by the purchaser through the opening 10 in' the front of the casing 1I; Any

desired size, shape and design of casing may be employed.

The lock employed in this form ofthe machine is the same asthat shown andy described in-my Patent No; 1,876,510 and comprises the coin entering slot 39 in the coin runway'38; the push "rod 131; thelock 42, and'operating `mechanism therefor.

For receiving the coins 40 as they leave the lock after having released the same, and for exposing them to the View of the public, I have provided at a point below the shaft I3 and rotatably mounted in the upright II, a shaft 12, and on the same plane therewith and in the forward end of the casing 1I, I have placed another parallel shaft 13, and upon these shafts 12 and 13 there is mounted upon the rollers an endless belt coin conveyor 14, which is operated by a sprocket wheel 1li` mounted upon the shaft 12 and driven by a chain 11 from a sprocket wheel 18 mounted on the shaft I3, in such a manner that the belt conveyor 14 will travel the required distance forward for each discharge or vending movement of the article conveyor I6, or a suflicient distance so that the coins 4I) as they are discharged fro-m the chute 38 will drop upon the coin conveyor 14 and be exposed through the glass table 19, remaining upon the conveyor 14 until the next purchase takes place at which time they will drop into the coin box 58.

In my Patent No. 1,876,510 and as shown in Figures l, 2, 3 and 4 of this application, the article conveyor I6 is operated by gravity caused by the weight of the articles being vended, but in the modied and preferred form shown in the Figures 5 and 6, the article conveyor I8 is operated in a positive manner by a hand lever 8|, operated by the purchaser.

This hand lever 8| is pivoted at its lower end as at 82 to the casing 1| or some other part of the machine and may be reciprocated through the guide slot 83 formed in the glass table 19, or other part of the casing; an-d in its normal position a portion of it contacts with the end of the plunger 31.

To the upper portion of the lock plate 23 are secured two brackets 84 having transverse bearings within which are freely rotatably mounted the shafts 85 which carry the flanged guide rollers 8S which support and guide a toothed rack 81, which is in mesh with and is adapted to rotate a spur gear 88 freely rotatably mounted on a shaft 89 located in the upright To this same shaft 89 is secured in a rigid manner a ratchet wheel 98 engaged by a pawl 9| mounted on the side of the gear 88, in such a manner that by the movement of the rack 81 in one direction the pawl 9| will engage the ratchet 98 and drive the shaft 89, while when the rack 81 is moved in the opposite direction the pawl 9| will travel over the teeth of the ratchet 90 and the shaft 89 will remain idle.

Upon this shaft 89 is also secured a spur gear 92 which is in mesh with and rotates the combined sprocket and gear l5 upon which the conveyor I6 is mounted.

For reciprocating the rack 81, there is provided an arm 93 which is pivoted at its lower end as at 94 to the plate 23 and is connected at its upper end to the rack 81 by a link 95.

To normally retain the rack 81 in the position shown in Figure 5, the arm 93 is provided with a transverse hole 96 through which extends one end of a rod 91 which is slidably mounted in` a bearing 98 on the plate 23; said rod 91 having a head 99 held in contact with the arm 93 by a spring |00 and stop |0| mounted on said rod 91; the inner end of the rod 91 contacting with a pin |02 on the release wheel 24; said arm 93 held under tension by the spring |83 attached thereto and to the plate 23.

To actuate the arm 93 against the tension of the spring |83 for the purpose of moving the rack 81 inward, there is provided a rod |22, the outer end of which is pivoted as at |23 to the hand lever 8|, and the inner end of which is slidably mounted in a bearing |86 attached to the end of one of the shafts 85, and abutting the arm 93.

The proper coin 40 having been inserted into the slot 39 to release the lock mechanism which is described in my Patents Nos. 1,827,900 and 1,864,847, the operator pushes inward on the hand lever 8| toward the casing 1|, which in turn presses inward on the end of the plunger 31 to operate the escapement, and at the same time moves inward on the rod |22 causing the arm 93 to move inward toward the back of the machine and carrying with it the rack 81 which rotates the gear 88 to release the rod 91 from the pin |02, allowing the escapement to operate, as a brake only.

After the hand lever 8| has reached the limit of its inward movement, it is vpulled outward or back tol its original position and on this outward travel the gear 88 by the action of the pawl 9| and the ratchet 98 will rotate the shaft 89 and thereby the gears 92 and |5 imparting a positive downward movement to the conveyor I6 to bring the articles into a delivery position, one at a time.

It will thus be seen that in this manner the action of the conveyor is rendered positive and the weight of the articles to be vended is not depended upon to move the conveyor.

The gravity method was not positive as the weight of the articles varied and grew less as they were removed.

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

In a coin display means for vending machines comprising a casing, a transparent shelf carried and forming a part of the casing, a coin receiving chute adjacent one end of the shelf, an endless coin receiving belt in the casing, a Coin storage chamber beneath the belt, said belt being of a width greater than the diameters of the coins deposited thereon and having an unobstructed surface adapted to have its upper stretch presented under the coin chute to receive the coins thereon in Various positions before being conveyed to the storage chamber, said belt having its side edges spaced from the side walls of the casing a distance less than the diameters of the coins, and means for imparting movement to the belt.

GEORGE MORRISON.
