ELECTRIC WAFFLE IRON.

Application filed May 31,

My invention relates to electric wafile irons and the object is to provide a simple, inex- .pensive and highly eflicient device of said kind and the use of whichenables an operator to bake one waflle while the batter for another one is being poured. Other objects of the invention and details'of construction are hereinafter set forth and illustrated in the accompanying drawing in which Fig. 1 is a side elevation of a preferred form of my device and Fig. 2 is a rear elevation of Fig. 1 with opposite side portions of the device removed.

Fig. 3 is a detail side view of the rear upper part of Fig. 1 showing the hinged parts of the device in two selective positions.

Fig. dis a modification of Fig. 3 and a toasting attachment added.

Fig. 5 is a side elevation of Fig.1 moditied to include both front and rear hinge devices.

Fig. 6 is an enlarged partial rear view of Fig. 5 showing mainly the hinge details about as at line 66 in said Fig. 5.

Referring to the drawing by reference numerals my device comprises triple electric heating elements, designated A for the top one, B for the center one and C for the lower one and all suitably connected by hinge means of variable construction as Wlll presently be fully described said hinge construction being such in all cases that the heater sections are separable selectively from eachother. In Figs. 1 and 2 the heater section C is fixed to a flared base 10 having an inlet aperture 11 for insertion of an insulated electric cable 12 the wires of which are suitably diverged within the side base andadapted to complete circuit to. resistance coils (not shown) in all the heater sections, said wires to sections A and B being designated 12 and 12 respectively. It will be understood that the adjacent faces of therespective sections may be of any suitable design but arranged so that when the device is closed the said faces are spaced apart, and

the adjacent perimetral edges of said sections preferably beaded or rounded as 13. 14

and 14 are two parallel outwardly directed handles on the front parts. of sections A and B respectively. 15 and 16 are respectively, upper and lower pivot pins rearward of and in alinement with the upper and lower flanges 13 respectively of center heater B,

said heater B having two horizontally spaced rearwardly directed cars 17 in which' said I 1927. Serial m5. 195,271.

pins arejournaled. The upper pin 15 also pivotally engages the rearwardly directed cars 22 of heater A whereas the fixed lower heater C has like cars 19 for pin 16. Ears 22 of section A have each a rearward projection with a downwardly exposed face 22 and cars 19 have a rearward projection with a-vertical face 19 adapted to be engaged by face 22 when sections A and B are raised together as to dotted line position in Fig. 3. If, however only section A- is raised'it swings on pivot 15 as to full line position in Fig. 3 and its face 15 stops against the vertical rear face 19 of the cars 17 on section B. It

is obvious that the center heater B has up- I wardly and downwardly exposed heating areas whereas section A has only a downa horizontal pin 21 protruding slightly both ways from. the outer sides of said ears 1 1-. In this instance section B has no ears 123, but the ears 19 of section C are provided each with and inwardly opening curved groove 19*, concentric of pivot 16. 'Ihus when heater sections A and B are raised together by handle 14 the projecting ends of pin 21 will be guided in. the grooves 19 when said two sections are swung back as to dotted line position in Fig. 5. I

It is now obvious that when a person desires to make waflies in the form of my device shown'in any of Figs. 1 to 6 inclusive he'zfirst closes circuit to the device so all the sections will get'properly heated. Then the operator raises sections A and B and pours "batter on the upwardly exposed heated-area of section G. Then sections A and B are let down on top of the batter which begins to bake atonce, having two heated areas for the purpose. Then while this waflie is being baked the top section is raised from section B and batter is put on the face of said latter section and the cover section A is allowed to be swung downwardly to rest thereon. It is also obvious that an operator can first place batter on the top of section B and then later on top of section C, but either way one wafile will be baking while the other is being and the pins 16 in horizontal spaced 15 position causing the center heater B to remain upright. 37 are U-shaped spring clips adapted to be slipped under the'section B and upwardly so the inwardly sprung upper arm parts 57 can be employed to hold bread slices against either or both of the heated faces of section.

It may be advisable in theconstruction of my device to have the pivoted connections slightly loose or in slotted apertures of the ears to provide for slight spreading of the sections when the batter expands right after being'placed in the device.

. What I claim:

1.- An electric wafile iron comprising three flat heating sections'arranged normally in vertical alinement, and lying concentric of each other, the center section having upwardly and downwardly exposed heating areas, the top section having a downwardly exposed heating area and the lower section having an upwardly fexposed heating area, vertically spaced hinge means connecting the adjacent sections, rearwardly directed ears on said center section comprising journal means for an upper and a lower hinge pin, ears on said upper and lower sections hinged respectively on said upper and lower pins, means on the front end of each of the two top sections for engagement to' selectively lift the top section on said upper pin and to both be engaged to'lift both upper sections away from the lowest section on the lower of said hinge pins.

2. The structure specified in claim 1, and a base for rigidly holding said lowest section. in horizontal plane.

3. The structure specified in claim 1, said ears of the upper section having a. rearwardly and downwardly exposed projection rearward of the hinge pin, and said lowest section having a vertical and rearwardly exposed face adapted to be engaged 'by said first projection when the two upper sections are swung upwardly and rearwardly on the lower hinge pin and when said upper sections are in a plane at an obtuse angle ,to the heating face of the lowest sectipn.

In testimony whereof I aflix my signature.
