and to means .for ,heating or retaining the heat and to means b-ylwhichrthe various movements 'in such articles.

The @invention relates to: means by which the sandwiches are .stored the dispensing drum;

The objects of the invention are:

To provide a dispensing apparatus having a carrierinwhichalargenumber of articles :tobe

doors "l i, l2 and i3 are hinged at their rear ends I as by hinges l4 and are each provided at their,,; 5 7

forward ends with a hasp and staple [5, with which a suitable look (not here shown) may be used, the doors thus formed being openableto replenish the stock of sandwiches in the carriers, or for other access to the interior of the casing.

Disposed within the casing are three frames 2% built preferably of angle-iron, there being one These frames have each a pair of angle-iron members 2|, which members support bearings 22. Each carrier is pro- 4' vvided with ;a shaft 23, journalled in a pair of these Secured to the shaft 23, as by apin 24 is a hub 25. 26 is a disc concentric withthe shaft 23 and secured to the hub 25 as by rivets 27. The periphery of the disc 26 is partially cut away l 20 to leave protruding equally spaced lugs 28, there being one lug for each of the article holding pockets. .29 is a cylindrical shell concentric with shaft 23 and having flanged portions which ,25 At its opposite end the shell 29 is provided with flange portions,32 which are secured as by rivets to an annular disc 33. q 34 area plurality of radie allyldisposed partitions which extend from the shell .29 outward between the discs 26 and '33, .30

being secured to these discs as by welding. The spacesbetween the partitions, form pockets 35, injwhich pockets the individual packages are disposed.

The carriers thus constructed are given a step.35 by step movement by plungersflll, there being an individualplunger for each carrier, these plungers are coupled to, and ,their movement controlled,

by coincontrol mechanisms 4|, one for each plunger, these mechanismsbeing purchasable in o the open market and described in detailin patents such as #2025321, January 7, 1936. For each plunger there is a plunger arm 42 which is hingedly connected as by a .pin @3 to a plunger Y link 44. The plunger link Mhasla fork 4iwhichfla5,

. link has a limited movement along theperipherv of thedisc 2% before engagement of the end 46 of the linkwith the .1ugl28 takes place. i Disposed above thelink M is a latch armrifl hingedly connected as by a pin 51 to a portion '52 55 spring secured as by screws 56 to the frame memengagement.

At its opposite end the rocker bar, carries a downwardly turned latch portion 66, substantially identical in construction with the latch 53. Secured to the under side of the latch arm 531s a cam member 6| which is adapted to be engaged and raised by a cam 62.

, able engagement.

forming a part of the frame.

through the opening and into the chute.

Cam 62 is pivotally mounted on the link 44 by a pivot pin 63. 64 is a stop, and 65 a spring urging the cam 62 against the stop.

I0 are discharge chutes, there being one for each of the carriers. These discharge chutes extend from the exterior of the casing I!) through suitable openings therein into proximity to the periphery of the carrier.

II are arcuate bands one for each carrier. Each band is concentric with, and lies adjacent the periphery of its carrier, though not necessarily in intimate proximity thereto. The band is supported at one end by a frame member I2, about level with the center of the carrier, and at its opposite end as by a bar I3, also From the bar end of each frame, a continuing arcuate extension band I4 extends above the carrier center and has side walls I5 extending into supporting engagement with the frame 20. Each band is interrupted or otherwise provided with an opening I6 which is alined with the chute III so that when any pocket of the carrier reaches the pocket position -A, Fig. 6, it comes into alinement with the opening I6 and the chute III, and the content of the pocket is free to slidev outward and discharge TI is an arcuate shutter exterior to the band I4, this shutter having an opening I8, shown in register with the opening I6, and being slidably mounted so that it may be shifted with respect to the band to close the opening. I9 are guides holding the shutter "II, in such slid- At its upper end the shutter 11 is provided with an outwardly turned flange or lug 86. BI is a chain secured at one end to the lug and at the opposite end supported as by a pin 82 extending from the carrier frame.

N The shutter 11 is shiftable when its corresponding door (II, I2 or I3) is open, by pulling upward on the chain 8| to shift the shutter opening. I8 relative to the opening I6, and effect closing of the latteropening during filling of the pockets.

65 is a dog pivotally secured as through a pin, and bracket 86, to a frame member 37, this dog being resiliently urged by a spring 88 into engagement with the lugs 28 in succession to prevent retrogressive movement of the carrier.

89 is an electrical ,heating pad substantially concentric with and lying adjacent to the cylinsupported by frame members 90.

BI is a cable carrying circuit Wires 92 leading to this heating pad, the cable 9! having a continuation 93 extending beyond the casing and leading from a suitable source of current.

95 is a bracket secured to the bar I3. 96 is a block of insulating material fixedly carried by the bracket 95; 91 a contact point carried by the block, and 98 a circuit lead. 99 is a second block of insulation carrying 'a complementary contact point IIIIJ. The block 99 is pivotably carried by the bracket 95 and has an arm II which extends through a slot I62 in the slide I1, and through an opening I63 in the band extension I4 and has an extension I64 adapted to be held against the inner surface of the band I4 by an article, such as a sandwich, I05, within the pocket in the position 35B adjacent the openings I6 and I8. I06 is a spring acting on the arm IIII, which spring when the pocket in the position 35-A is empty, brings the points 91 and I60 into contact, and completes the circuit to a signal light IIlI on the front of the casing, indicating that the pocket is empty.

In the use of the device, one of the doors-t (II, I2 or I3) covering a carrier therebelow is opened and the sandwiches or other articles to be dispensed are dropped into the pockets 35, the latch arm 56 being raised from engagement with the lugs 28 and the carrier being advanced step by step as filling is carried on. As filling I progresses the filled pockets move toward alinement with the openings I6 and I8, through which discharge is effected into the chute 10. At some time before this point is reached the chain 84"" is grasped and the shutter 11 raised to close the opening I6 and permit complete filling of all the pockets. After filling has been accomplished the chain 84 is released and the shutter 'I'I allowed to drop to place, reestablishing alinement of the openings I6 and I8 and allowing immediate discharge of the article from the pocket which is in the position 35-A. The door above the carrier is then closed and locked, the operation being repeated for each of the three carriers shown, or for as many carriers as there may be, should the casings accommodate a different number than are shown.

With the carriers filled, the customer drops a coin of the proper denomination in the coin slot of the coin control apparatus II and pushes in the plunger related thereto. This inward movement slides the fork along the rim of the disc 26 and brings the cam 62 into engagement with the cam member SI, and, the move ment of the plunger continuing, raises the latch arm 50. This movement disengages the latch 53 from lug engagement at about the same time that the end 46 of the plunger engages a lug the latch 53 to accomplish this disengagement tilts the arm 51 upward, where it rests on top of the latch arm 50, and moves the latch 60 downward into the path of a lug in the position 28-'-B. Continued movement of the plunger 42 shifts the disc 26 a full pocket space. In accomplishing this shift the cam 62 slides under the cam member BI during the time that it is necessary for the latch 53 to be raised to permit the passage therebeneath of a lug moving from the position 28C, and after such lug movement has been accomplished the cam clears the cam member 6|, allowing the latch arm to drop and the latch 53 to resume lug engaging position. This movement also permits the cam 5'! 'in the position 28A.
