Corresponding and like parts are referred to in the following description, and designated in the several views of the accorn panying drawings, by similar reference characters.

The casing of the vending machine comprises a bottom 1, a lower back section 2,

county of Jefferson anda State of Kentucky, have invented certain and sides 3 forwardly pr integral. Th

movably retained in place integrally with the sides with a mirror sight; opening portions 3 an having upper portions 3 of L reduced width.

These parts together with a ojecting tray a are preferably e front 5 of the casing is reby lugs 6 formed 3, and is provided 7 and a horizontal row of 8 closed by glass panels 9. carrier comprises a plate 10 rear edges of the side d which is provided at its inner s The article side with vertically extending angular members 11. plate provide These members together with the article receiving compartments 12 in front sides of which are vertical slots The upp er portion of the plate 10 constitutes the upper back section of the casing, and the lower portion thereof extends down-- wardly into the casing in forwardly spaced relation with tion 2. A top 14 is secured to the edge of the plate 10 by closes the upper partments 12.

respect to the lower back secupper hinges 15, and it ends of the casing and com- .A lock 16 carried by the front 5 and engaging the top 141 prevents the unauthorized removal of the former and the unauthorized opening of the latter. A door 17 resting upon the inclined upper edges 18 of the sides 3, secured at its lower edge to the upper edge of the lower back section by hinges 19, and secured in closed position by a that free access may lock 20, is provided in order be gained to the dispensing mechanism of the machine for the purpose of inspection or repair.

The machi the purpose ne is especially designed for of vending cakes of soap in factories, ofiices and the like, and the cakes of soap 21 are arranged ments 12 and ends of guides 22. A wardly extending within the comparttherein by the front downwardly and forpartition 23 is secured supported within the casing below the guides 22, and

is adapted to direct the articles pushed from the compartments 12 into the tray 41. The

partition 23 24 to permit is provided with side flanges it to be bolted to the sides 3.

A coin receiving drawer 25 is located within the casing in rear of the partition 23, and is removablethrough one of the sides 3. The drawer 25 is slidably mounted upon the bottom 1 between guides 26, and is provided with a lock closed positio 27 by which it is secured in n.

Each of the guides 22 comprises a plate 28 resting upon and bolted to a rib 29 formed integrally with the lower back section 2 and a flange 30 extending rearwardly from the upper end of the partition 23. The plates 23 are provided with side flanges 31, the front portions 31 of which are higher than their rear port-ions 31 The flange portions 31 are located within the lower ends of the compartments 12-and the articles 21 are supported directly thereby. The plates 23 are provided vith openings 32 located above the drawer 25 so that when a coin is released from one of the pushers 33 it will fall into the drawer. The pushers 33 are slidably mounted upon the plates 23 between the flanges 31, and are provided with coin receiving slots 3t which gradual ly increase in width in the direction of the lower sides of the p hers. The pusher-s '2 are provided with horizontal grooves 35 which intersect the slots 3t and which open out through the ends thereof and receive coin stops 36. The coin stops 36 prevent the passage of coins through the slots 3% until the pushers 33 have been moved far enough to carry their slots 3t beyond the forward ends of the stops. When the pushers 33 reach this position the lowermost of the articles 21 will have been discharged from the compartments l2 and the coins will pass through the slots 3d and openings 32 into the drawer 25. The pushers 33 are yieldingly retained in retracted position against stops 3'? by springs 38 secured to the pushers and lower back section 2, and when in this position there coin slots 34 are partly closed by the stops 36. The pushers 33 are adapted to be moved forward 1y by pulls 39 of U-shape. The side members 410 of the pulls 39 pass through slots etl in the compartnient forming members 11 and lots 42 in the front 5, the slots opening out through the lower ends of the parts in which they are formed in order to permit the removal of the article carrier and the front The inner ends of the pull members are connected to trunnions which are carried by the pushers 33, and they are secured to the trunnions by cotter keys 4st. The cross members 45 of the pulls 39 provide hand grips, and secured to the pull members 40 between the pull members t5 and the front 5 are cross pieces as which when the pushers 33 are in normal position contact with the front 5. The pushers 33 are held against any but forward and rearward sliding movements on the plates 23 by the flanges 31 and the coin stops 36.

A gravity actuating detent 4:7 is provided for each pusher 33. The detents 47 rest upon the pushers 33, and have their rear ends pivoted as at L3 to the lower back section 2, and are provided at their forward ends with depending hooks i9 which when the pushers 33 are in normal position occupy a position slightly forward of the front ends of the pushers. The detents 4C7 extend over the coin slots 3t and are notched as at 50 to accommodate the lower ends of coin chutes 51 which communicate at their lower ends with the slots. In their under sides the detents 1? are provided with cam portions which are arranged slightly in advance of openings 53 in the front sides of the coin chutes 51. During the initial phase of the forward movement of the pushers 33, the upper edges of the coins contact with the cam surfaces and raise the detents 4-? far enough to carry their hooks out of the path of the carriers. After the coins pass the cam portions 52 they contact with the under sides of the detents 1 7 and support the detents until the carriers 33 have been moved far enough to carry the coins beyond the front ends of the steps 36. whereupon the coins will pass through the slots 35 and openings into the drawer and the detents 4:7 will fall until their books as contact with the upper sides of the pushers 3 W hen the pushers 33 are released they will be returned to their normal positions by the springs 33, and when they reach such position the detents 47 will gravitate to their normal positions.

A follower is mounted upon each stack of the articles 2i, and carries a sign 55 hearing the word Empty. hen all of the articles 21 in any of the compartments 12 have been sold, the follower 54: will rest upon the flange portions 31 with the sign in front of the opening 3 registering with the empty compartment.

The distance that the stops 36 extend across the slots 34: depends upon the diam eter of the coin representing the price of the articles Lit, and this distance is such that the stops 36 will support a proper coin and thus permit the actuation of the pusher-s 33 while a smaller coin will pass freely through the slots 3 and openings 32 into the drawer All parts of the machine are made of metal, and the casing, article carrier, front 5, top 14-, door 17, and partition 23 are preferably made of aluminum. If desired the machine may be used for vending articles other than soap.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation of the vending machine will be readily apparent to those skilled in the art to which it appertains. While I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made therein when desired as are within the scope of the invention as claimed.
