rlhe invention relates to machines for the manufacture of sugar wafers or the like, and it consists in the novel construction and combinations of parts as hereinafter set forth.
ln the accompanyino drawings, illustrating the invention, the lletter a, designates an oven inclosure of sheet metal havingl bestoslining o, to prevent undue escape of heat, said oven having an upoer segmental recess of substantially the same length as the diameter of the oven.
o, is a base lying within such inclosnre and upon which a rotary circular table al, rests, through centrally located ball hearings (Z, such table having anti-friction roller supports e, at the circumference or outer portion thereof, said` rollers having movement and bearing upon a Acircular track f, supported from the base o. This table has a segmental portion thereof lying without the oven in the segmental recess thereof.
(j, g, represents a` radially arranged series of baking pans which have small securing screws g', unit-ing the pansto the table lol, a number of such screws, usually 16, being provided, as shown. These pans g, g, have each hinged covers g2, g2, carrying at their free ends rollers li, one roller being provided for each cover, said rollers normally engag- Specification ot Letters Patent.

serial no. entre ing an. arcuate track e", located above the same within the segmental. oven recess and serving lo keep the covers tightly closed. during;` the cooking of the pan contents.
lhe oven inclosure o, is of cylindrical form, having` an arched cover a', and a, straight or vertical front wall (l2, of chord character extendingI from said cover o', down to the rotary table al. ln this way the upper portion of the oven lying above the rotary table is provided with a cylinder wall j, ex tending" through an arc of about 210 degrecs, an arched cover, and a vertical front Wall. ln order to raise the covers g2, y2, of the baking pans when it is desired to remove the contents thereof and recharge the same, the rollers i, li., of such covers, as they' emerge with the pans through the vertical front Wall a2, (which is suitably cut away for this purpose as shown in Fig. 3 of the drawings) pass upon ay cani track la, where-- by the hinged covers are gradually lifted to an angle of about (l0 degrees and closed again before the haltingpans reenter the inclosure.
llintonlatically operating means are provided for feeding the dough to the pans, such means consisting; in a feed chute or spout Z, the mouth Z, of which is controlled by a plate valve m, having extensions m', upon opposite sides of its pivot m2. This pivot rod m32, is provided at one end with a` four branched wheel n, the branches n", of which are adapted to engage pins o, o', of the baking pans, cach pan having two pins. ln this way as the baking pan approaches the wheel a, the lirst pin o, strikes a branch n', of the wheel and turns the saine, together with the attached valve, through an arc of ninety degrees, whereby the valve is opened, as shown in full lines in Fig'. 6. As the pan is about to pass to the other side of the Wheel n, the pin o', is caused to strike another arni of the Wheel n, whereby such wheel and the Yalve is turned again to the same extent, closingI the valve as shown in dotted lines in said ligure. The contracted.
mouth Z', of the chute or spout Z, is provided with a slidevalve 79, below the valve m, whereby the speed of the discharge of the dough may be controlled.
Q, is a horizontal power shaft having bevel gear connection Q', with a vertical shaft g2, which is keyed to the rotary table r, is a damper in ventilating pipe r', eirtltl tending upward from the center of the arched cover or the oven. i
s, are radial braces for the oven walls located above the rotary table and from which the track z', is suspended.
In orderfto accomplish the cooking of the wafers and to heat the oven l have shown a gas pipe t, having'parallel branches t', located below the baking pans, said parallel branches having upward projecting burners t2, located in close proximity to the pans and below the saine, whereby the llames from said burners are caused to strike directly upon the bottoms of the -pans as they move pas'tsuch burners. A. similar' heating device u, located above the baking pans at a point in the oven beyond the heating device lirst referred to, its downward projecting burners u, being arranged in close proximity to the closed hinged covers of the pans,
'whereby the tops as well as the bottoms of vthe wafers will be perfectly cooked.
A simple and elicient machine for the purpose is thus provided, only one attendant being required, whose duty it will be to remove the wafers from the baking pans as the covers thereof are raised.
Having described the invention, what l claims-and desire to secure by Letters latent is:
l. In a machine of the class described, the combination olf a cylindric -oven having an upper recess of substantially the same ,length as that of the diameter of the oven,
a rotary table within said oven and having a portion thereof lying without the oven in said recess, a radially arranged series ol? baking pans upon said table, said pans having each a hinged cover `provided with an end ibller, 'a cam track located within the said ficessaof the oven and. with which the end :rollers'of the pan covers have engagement,
to raise and lower the same upon movement of the table.
2. ln a machine of the class described, the combination of a cylindric oven having an upper recess, a rotary table within said oven and having a portionthereof lying without the ov'en in saidrocess, radially arranged series of baking pans upon said table, said pans having each a. hinged cover, a cam track located within the recess ol. the oven and with which the end rollers of the pan covers have engagement to raise and lower the same upon movement of the table, and an arcuate track within the oven and with which the end rollers of the pan covers have engagement to keep said covers closed.
3. In a machine of the class described, the combination ot' ay cylindric oven having an upper recess, arotary table within said oven and having a portion thereoit" lying witliout the oven in said recess, a circular tra-ck, supporting rollers carried by the circumferential portion ot' said table and traveling upon said track, a radially arranged series of baking pans upon said table, said pans having each a hinged cov'er, a cam track located within the recess of the oven and with which the end rollers of the pan covers have cngagoinent to raise and`lowcr the same upon 'movement of the table, an arcuate track located within th oven and with which thc end rollers of the pan covers have engagement to keep said covers closed, and a feed spout for dough loca lcd in said oven recess over the table.
et. In a machine o'lI the class described, thc combination of an oven, a rotary table, baking pans carried by said table, and a lccd spout for dough having a valve provided with a star wheel, said baking paus having each pins having engagement with said star wheel to automatically open and close said valve.
5. in a machine of the class described, the combination of an oven, a rotary table having a small portion thereof located withoutl the oven, baking pans carried by said table, and adapted to pass with said table without the oven, a feed spout for dough located without thc oven over said table and having a valve provid cd with a star wheel, said baking pans having cach pins having engage nient with said star wheel to automatically control said valve.
Guin a machine of the class described, the ,combination of an oven, a rotary table having a small portion thereof located without the oven. baking paus carried by said table and adapted to pass with said table without the oven, a i'eed spout for dough located without the oven ovcr'said table and having a valve provided with a star wheel, said baking pans having cach matically control said valve, said spout having a slldc valve tor controlling the speed of the dough discharge.
