'Application filed October 29, 1920. SerialNo. 420,457.

To all whom t may concer/n.' Y

Be it known that I, F RANK A. SELL, a citizen of the United States, residing at Portland, in the county of'Multnomah and State of Oregon, have invented certain new and useful Improvements in a VValile-Machine; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same.

The object of the invention is to provide a comparatively simple and efiicient apparatus for cooking waflles without necessitating the turning of the waflie iron and hence under such conditions as to materially expedite the operation of preparing` the waffles, it being understood that the device is especially 'designed for use in those establishments such as hotels and restaurants where waffles are prepared in large quantities or must be prepared quickly in order to promptly fill orders; and with this object in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the drawings, wherein:

Figure 1 is a side view of an apparatus embodying the invention.

Fig. 2 is a longitudinal sectional view of the same.

Fig. 3 is a transverse sectional view on the plane indicated by the line 3-3 of Fig. 2.

Fig. 4 is a horizontal section on the plane indicated by the line 4-4 of Fig. 2.

In the drawings it has been deemed suicient to show a single unit of the apparatus embodying the invention with the explanations that any desired number of such units may be used in a battery for attention by the same operator if required, to suit the demand of the establishment, said unit consisting essentially of an oven 10 provided at opposite sides with longitudinal tracks 11 for the support of a walile iron 12, upper and lower burner tubes or equivalent heating units 13 and 14 being arranged respectively above and below the plane of the tracks for applicationl of heat simultaneously to the upper and lower sides ofthe waffle iron. Preferably the top of the oven is provided with the downwardly convergent battle plates 15 meeting adjacent to the upper burner or heating unit, with steam and smoke outlets 16 at the upper edges thereof, and where gas is used as the fuel the upper burner tube is Patented Nov. 1, 192.1.

provi-ded with downwardly and outwardly directed orifices 17 so as to project the flame in such directions, indicated by the arrows 1n Fig. 3 as to cause the heat to impinge effectively upon the upper side of the waliie iron to insure a substantially equal application of heat to both the upper and lower surfaces and thus to cook the waffle equally on both sides without necessitating the turning thereof or removal of the iron from the oven after it has been inserted thereinto.

The furnace may be provided with a forj wardly projecting rest 18 to receive and support the iron when withdrawn from the oven so as to permit of the raising of the upper section 19 of the arms to expose and permit the removal of the waliie, a stop 20 being arranged at the forward edge of said rest to limit the forward movement of the iron.

Also the front of the oven may be provided with a suitable draft regulator 21.

The iron preferably consists of lower and upper sections or members hinged as indicated at 22 with the upper member provided with a handle 23 by which it may be raised to expose the waffle, and the lower member of the iron is provided with transverse front and rear bars 24 for terminal engagement with the tracks l1 to support the iron in its movement into and out of the oven.

The joint by which the upper and lower sections of the iron are connected consists of the twin ears 25 on one section between which is interposed the ears 26 of the other section, and a hinge pin 27, which extends through a slot 28 in one of the ears so as to permit of upward movement of the upper section of the arm as the waiiie rises. A stud 30 on the upper section of the arm is adapted for engagement with a seat 31 to prevent disalinement of the hinge members as the sections separate, and at the front or free end of the upper section are provided studs 32 for engaging seats 33 in the cross bar 24 for a similar purpose. In the construction illustrated the waffle iron'is made of elliptical form in plan as being the most economical in the matter of space occupied, the longer axis of the ellipse being disposed longitudinally of the oven so that when a plurality of oven units are arranged side by side, the lateral space occupied may not be such as to cause inconvenience to a single operator in attending to or serving a plurality of said units.
