VENDING-MACHINE.

Specification of Letters Patent.

Patented Aug. 8, 1911.

Application filed November 15, 1906. Serial No. 343,488..

To all whom it may concern:

Be it known that I, J oHN SCHMIDT, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented a new and useful Improvement in Vending-Machines, of which the following is a specification.

rThis invention relates to vending machines, and particularly to machines for vending cigars.

It has for its principal objects to produce novel mechanism adapted to feed cigars from a box or receptacle to the delivery mechanism of the machine; to produce a novel mechanism in conjunction with said feeding mechanism whereby cigars may be delivered one by one, or in predetermined numbers from the machine; and to attain certain advantages hereinafter more fully set forth.

The invention consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed. v

ln the accompanying drawings which form part of this specification and wherein like symbols refer to like parts wherever they occur, Figure 1 is a view showing a portion of the case in section and one of the side frames removed to show the mechanism, the parts being in normal position; Fig. 2 is a view of the mechanism partially operated; Fig. 3 is a fragmentary view showing the reverse arrangement of the respective ratchets for the feed-apron rolls; Fig. 4 is a section on line 4-4 of Fig. 3; Fig. 5 is a detail vperspective view showing relative arrangement of feed aprons and delivery cylinders; Fig. 6 is a longitudinal section through the delivery cylinder; Fig. 7 is a detachedview of the resilient false bottom for the pockets in the delivery cylinder and the securing plate therefor; Fig. 8 is a view showing the actuating mechanism at one extreme of its movement; Fig. 9 is a detail view showing the action of the actuating pawl and latchtripping hook during the return stroke of the actuating bar; and, Fig. 10 is a fragmentary View partly in section showing the guard or retainer in coperative relation to the delivery cylinder.

The actuating mechanism of the machine illustrated in the accompanying drawings is of the coin-actuated type, and, in many respects, is substantially the same as that disclosed in U. S. Letters Patent No. 811,501,

granted to J. Heinrich, et al., on January 30, 1906.

The mechanism of the entire machine is incased within a housing 1. comprises a base-plate 2 having upturned side portions 3 to which are attached extension-plates 4. The side portions 3 and extensions 4 constitute the side-frames, and they are provided with bearings for the several cross-shafts of the machine.

A box 5 having an open end is supported on an incline so that cigars contained therein can be discharged by gravity upon an endless apron or belt 6. The apron 6 is adapted to convey cigars to a rotatable delivery-cylinder 7 having parallel peripheral pockets 8 extending longitudinally thereof. The pockets 8 of the delivery-cylinder are provided with false bottoms 9. These false bottoms are yieldingly supported by springs 10 which are loosely held within the pockets by plates 11 having turned-over end portions 12 under which the ends of the springs rest. The pockets in the delivery-cylinder, as shown in the drawings, are adapted to receive a single cigar, with the exception of the pocket 8a which is of a depth suflcient to receive two cigars, the purpose of which will be hereinafter explained.

Mounted at a slight distance above the delivery-cylinder, just a little in advance of a pocket in the normal position of said cylinder, is a shaft 13. Above this shaft 13 is arranged an endless apron or belt 14 which is adapted to travel downwardly on its side toward the cigar box or receptacle 5. The apron 6 is carried by a shaft 15 and a roll 16 mounted on a shaft 17. Loosely mounted on the shaft 17 is a sprocket wheel 18 having a hub portion which is provided with a series of ratchet teeth 19. The sprocket wheel 18 is yieldingly held with its ratchet teeth in engagement with a pin 20 on the shaft 17 by a spring 21. The teeth 19 are so formed that they will hold against the pin only when the sprocket wheel is rotated in one direction. The apron 14 is carried by a shaft 22 and a roll 23 mounted on a shaft 24. A. sprocket wheel 25 is loosely mounted on this shaft 24 in alinement with the sprocket wheel 18 on the opposite shaft 17. The sprocket wheel 25 is provided with ratchet teeth 26 similar to the teeth 19 on the wheel 18 but formed the reverse thereof. Aspring 27 yieldingly holds the sprocket The frame Y wheel 25 with its ratchet teeth in engagement with a pin 28 on the shaft 24. Fas-y tened to, or integral with the sprocket wheel 25 is a gear wheel 29 which is adapted to mesh with a pinion 30 on the shaft 13. An endless chain 33v passes around the sprocket wheels 18 and 25 and idler sprocket wheels 31 and 32. A spring 34 connects the chain at points between the idlers 31 and 32 and sprocket wheel 25 to maintain a tension upon said chain to take up the slack and keep it tight upon the sprocket wheels. The chain 33 is attached to a projection 35 on an oscillatory lever 36 pivoted near the base of the machine. This lever has a slotted or bifurcated portion 37 which engages a stud 38 on a horizontally-movable actuating-bar or plunger 39. A spring 40 yieldingly holds the oscillatory lever and plunger in their normal forward positions, and acts to restore the parts after the machine has been operated. c

The plunger 39 carries a spring-pressed pawl 41 which is adapted to engage a ratchet wheel 42 iXed on the shaft of the delivery cylinder. The delivery-cylinder is normally locked against forward rotation by a bell-crank pawl 43 which engages a second ratchet wheel 44 fixed on the shaft of the delivery-cylinder. One arm of the pawl 43 normally engages the ratchet wheel 44 and the opposite arm is connected by a link 45 to a dog 46. The free end of the dog 46 lies within a coin-passage and is adapted to be lifted by a coin which is moved toward the dog by the plunger 39. lvhen the dog 46 is lifted the bell-crank pawl 43 will be moved out of'engagement with the ratchet wheel 44, thereby leaving the delivery-cylinder 7 free to be rotated by a continuation of the inward movement of the plunger. The coin-controlled features and arrangements of coin-passages are substantially the same as disclosed in the Patent No. 811,501 hereinbefore referred to, and therefore will not be herein described in detail.

During the operation of the machine the coin X is passed successively through the coin-passages to the positions indicated in Figs. 1 and 2, and finally is pushed out through an opening 47 into a suitable receptacle (not shown) which may be provided, or simply dropped on the bottom of the case, as shown in Fig. 8.

In the operation of the machine, the plunger 39 upon being pushed inwardly will, by reason of its pawl 41 engaging the ratchet wheel 42 rotate the delivery-cylinder 7 a distance equal to the distance between the pockets 8. The moving plunger also rocks the lever 36. The endless sprocket chain 33 also travels with the oscillating lever to which it is attached. l/Vhen the plunger 39 is relieved of inward pressure the spring 40 will cause the lever 36 to swing outwardly and thereby move the plunger and sprocket chain to normal posit-ion. Thus it will be seen that the delivery-cylinder will be rotated during the inward movement of the plunger, but remains stationary during the return stroke owing to the ratchet and pawl arrangements, and that the sprocket-chain is caused to travel first in one direction and then returned to normal position. The arrangement of the ratchet teeth on the respect- ive sprocket wheels 18 and 25 is such, that during the inward movement of the plunger 39, the feed apron 6 is caused to travel in the direction indicated by arrows to feed the cigars to the delivery-cylinder, while the apron 14 remains stationary. During the return stroke of the plunger the apron 14 is caused to travel while the apron 6 remains stationary.

It is preferable that the feed-aprons 6 and 14 be made of elastic material so that a cushioning eHect is produced, and thereby prevent the cigars from being crushed or broken. By alternating the movement of the feed-aprons, jamming or wedging of the cigars is avoided, and perfect feeding of the cigars is accomplished. The cigars are received into the pockets upon the yielding false-bottoms 9. The depth of the pockets to the false bottom is approximately onehalf the diameter of a cigar, so that a cigar contained therein will project outside to prevent a. second cigar from entering, as clearly illustrated in Figs. 1 and 2. In Fig. 2 the parts are shown partially actuated. The parts are moving in the direction indicated by arrows. As the delivery cylinder is ro tated the cigar contained within the pocket is carried underthe roller 13 which is rotating at this time in the proper direction to assist the passage of said cigar thereunder. The yielding'false-bottom is depressed while the cigar is being thus carried forward under the roller. Aguard or retainer 48 is concentricallyV arranged relative to the delivery-cylinder and spaced therefrom a sufiicient distance to permit t-he springs 10 to react and restore the false-bottom to normal position, and also prevent binding or crushing the cigar during the continuation of rotation of the delivery-cylinder. As shown in F ig. 10 this retainer 48 is conveniently mounted on the side frame opposite to that on which the actuating mechanism is mounted. It extends substantially the length of the delivery-cylinder, and is of a width suff icient to retain a cigar within a pocket, as shown, until the machine is o-perated to deliver a cigar. The cigars are dropped by gravity from the delivery-cylinder into a trough 49 fro-m whence they rolloutside of the case through an opening 50.

While I have shown a machine adapted to deliver one cigar at a time, it is obvious that the respective pockets can be made of a capacity to receive and deliver a plurality of cigars. It will be noted that I have herein made provision for delivering two cigars from one of the pockets upon the insertion of a single coin. Thus at regular intervals the machine pays out two cigars for the price of one.

Obviously, my machine is capable of considerable modification within the scope of my invention, and I do not wish to be limited to the specific construction shown and described.
