39 to provide a roll a disk member 44 is` 41 being slidable in the drum 11. As shown in Fig. 8, there are three apertures 46 in the inner end of the drum 12, and the apertures 46 are registrable with the frankfurter spaces of the frame 23 and register with the apertures 37 formed in the cap 14. A ap 46a may be provided over each of the apertures 46 to close the same, the iiap 46a being suitably hinged to the inner end of the drum 12 so that the ap may swing upwardly. From the foregoing, it will be understood that the rod 42 may be connected to any one of the plungers 40 and manipulated to push a frankfurter, which may be in alignment therewith, out of the frame 23 and out of the drum 12 through one of the apertures 46, the rod 42 being slidable in the drum 12.

It will be understood that the slot 4S in the drum 11 registers with the apertures 46 in the drum 12.

The sandwich-assembling means 20 supported on the bed 19 is located between the slot 45 and the apertures 46. As shown in Figs. 9 and l0, the sandwich-assembling means comprises a lower part indicated generally by the numeral 47, and an upper part indicated generally by the numeral 48, the parts 47 and 48 being preferably of cast metal. The part 47 is elongated and generally trough-shaped, the sides 49 thereof being cut away at 50 intermediate their ends. The trough-shaped part 47 is open at one end and has an abutment 51 at the other end, the abutment 51 being cut away on an arc at 52. Cooperating with the trough-shaped part 47 is the upper part 48, the latter being a generally rectangular plate and provided with a lug 53 at each corner thereof engageable with corner surfaces 53a on the trough-shaped part 47 for support thereby. The plate part 48 has a top 54 extending longitudinally thereof intermediate the sides. Surrounding the top 45 on three sides thereof is a depending ange 55 generally of U shape and having its legs extending to one end of the plate part 48. The outer surfaces of the legs of the ange 55 meet in a ridge 55a, as shown in Fig. 10. As indicated in Figs. 7 and 8, the trough-shaped part 47 carries pins 56 at the underside thereof, one at each end, and the bed 19 is provided with recesses 56a to receive the pins 56, the recesses 56a being so positioned that the trough-shaped part 47 may be aligned with any one of the apertures 46, as indicated in Fig. 8. The plate part 4S may be secured to the underside of a closure member 57 constructed of sheet metal and hinged to a bracket 58 to swing upwardly, the latter being suitably fastened to the bed 19. Two thumb screws 9 may be provided for securing the plate part 48 to the closure member 57, the plate part 48 having two threaded holes, one at each end of the plate member, to receive the thumb screws 59. The thumb screws 59 may be passed through the closure member 57 so that the plate part 48 may be aligned with any of the apertures 46, the plate part 48 always being positioned directly over the trough-shaped part 47.

From the foregoing, it will be understood that when the rods 41 and 42 are aligned with the plungers to which they are hinged, as shown in Fig. l in dotted lines, the rods 41 and 42 may be pushed into the drums 11 and 12, respectively, feeding a roll and a frankfurter to the sandwich-assembling means 20. To assure alignment of the rods 41 and 42 with a frankfurter and a roll, respectively, a leaf spring 60 is secured at one end thereof to the left end of the trough-shaped part 47, the spring being located in a transverse slot 61 formed in the trough shaped part 47 and the spring 60 having a part 62 at the other end of the spring 60 engageable with any of the struts 29 of the frame 22, and movable into the slot 61 in the trough-shaped part 47 against the pressure of the spring 60, the arrangement being such that the part 62 is spring urged out of the slot 61 to resist rotation of the frames 22 and 23 by engagement with any of the struts 29, the rods 41 and 42 being aligned with a frankfurter and a roll, respectively, when the part 62 is so engaged. The part 62 is so shaped that the struts 29 ride over the part 62 against the pressure of the spring 60 when the frames 22 and 23 are rotated in either direction. It will be understood that the frames 22 and 23 are fixed to the shaft 21 and are in alignment with each other, the shaft 21 being rotatable manually by means of the knob 24.

In the operation of the device, the rod 41 is first used as described above to feed a roll to the sandwich-assembling means 20, the roll moving into the trough-shaped part 47 and being opened longitudinally by the ridge 5Sa of the flange 55. Movement of the roll may be arrested by engagement of the latter with the abutment 51 on the trough-shaped part, the sandwich-assembling means 20 comprising the trough-shaped part 47 being positioned s o as to be aligned with the plunger to which the rod 41 1s connected. The rod 42 connected to the plunger allgned with the sandwich-assembling means 20 is then used as described above to feed a frankfurter to the sandwichassembling means 20, the plate part 48 being disposed with the U-shaped depending flange 55 facing toward the frame 23, the latter guiding the frankfurter as it moves into the opened roll. Movement of the frankfurter may be arrested by engagement of the latter with the intermediate portion of the U-shaped flange 55. When the frankfurter is in this position the sandwich is assembled. The closure member 57 may then be opened to the position shown in Fig. 8 in dotted lines, and the sandwich lifted out of the trough-shaped member 47. When the closure member is again in lowered position, the operation may be repeated after first rotating the frames 22 and 23 by the knob 24 until the part 62 engages the next following strut 29 of the frame 22. The preferred practice is to connect the rods 41 and 42 to the outermost plungers 39 and 40, respectively, the sandwichassembling means 20 being positioned as shown in Fig. 8, and exhausting the radially outermost rolls and frankfurters, then progressively moving the rods 41 and 42 inwardly to the next plungers 39 and 40, respectively, and progressively moving the sandwich-assembling means 20 to the next inner position. When the rolls and frankfurters are completely exhausted, the caps 13 and 14 may be removed from the drums 11 and 12, respectively, as described above, and the frames 22 and 23 refilled, and the caps 13 and 14 replaced.

A heating element may be provided in association with the sandwich-making device to warm or cook food while the latter is in the device. In the preferred embodiment of the invention illustrated in the drawings, a sheet-metal water tank 63 is provided under the drum 12 and secured thereto as by welding (see Fig. l of the drawings). Under the tank 63 is a burner unit 64 comprising a suitable fuel reservoir, the unit 64 being supported from the tank 63 by a bracket 65, the latter preferably being welded to the tank. The drum 12 is provided with a suitable inner i11- sulating lining 66 having an opening 67 formed therein. The opening 67 registers with an opening 67a in the drum 2 A baffle plate 68 is located over the openings 67 and 673 and secured to the drum 12 as by welding. The bale plate 68 is perforated to receive one end of a conduit 69, the other end of the conduit 69 opening into the tank 63. The tank 63 is provided with a capped intake conduit 70, and may also be provided with a drain cock 71. A pair of drain conduits 72 lead through the lining 66 into the tank 63. The arrangement is such that heat generated by the burner 64 causes steam to be generated in the tank 63, the steam passing into the drum 12 through the conduit 69 and passing through the perforations in the channeled member 34, warming or cooking the frankfurters in the frame 23.

From the foregoing it will be evident that the sandwich-making device of the invention is unitary and selfcontained, the food articles therein being completely enclosed so as to be kept clean. The device is light and compact, and therefore may be carried easily from place to place, and in this connection it is to be noted that the device may be strapped to the operators shoulders and easily operated while so supported. Another advantage of the device is that it comprises few parts and is easily cleaned.

While the preferred embodiment of the invention is described herein and illustrated in the drawings, various modifications and changes may be made within the principles of the invention and the scope of the claims.
