. @ECZRIG GRIDDLE.
Application filed September 12, 1925, Serial No. 56,046. Renewed September 27, 1927.
More particularly my invention comprises improvements in the griddle top and the mounting of the heating elements thereln, and also to the structure of the base and the mounting of the insulating element therein.
In the accompanying drawings, wherein I have illustrated the best embodiment of the principles of my invention now known to me, Fig. 1 is a front elevation of the electric griddle, broken away in partial section along the line II in Fig. 2 to show parts; Fig. 2 is a bottom plan view of the griddle top on reduced scale; Fig. 3 is an end view of the electric griddle looking from the left in Fig.
1, the same being broken away in partlal section along the line III-III in Fig. 2; Fig. 4: is a. detail in section showing the means for securing the ends of the heating elements; Fig. 5 is an enlarged detail in :0 section along the line VV in Fig. 2; Flg.
6 is a broken plan view of theinsulatlng element and its pan, and Fig. 7 is a perspective of the locking member which connects to gether the bottom parts.
Referring in detail to thedraw1ngs,A represents the griddle top which 1s supported by. the inclosed base B, the base being supported at proper elevation by the feet C. represents the heating elements mounted in the top. E represents the insulating member, usually a mat of suitable material, such as asbestos felt, and which is contained in a pan F mounted in the base B.
The construction of the top, as shown, is as 5 follows.
'1 represents the top plate whose polished upper surface forms the cooking surface. This plate maybe of steel, cast iron or other suitable metal. I
0 To the under surface of the plate 1 are attached the two transversely disposed end bars 2 and the center bar 3. The bars 2 are set sufficiently in from the end of the plate 1 and the bars 2 and 3 are short enough to allow the plate 1 to rest'on the top of the base B with the bars 2 and 3 within the base, and the bars 2 are spaced inwardly frorrnthe ends of the plate 1 forv the same purpose.
The bars 2 and 3 are secured to the under side of the plate 1 by means of bolts 4:. I have shown nine of said bolts employed, one at each end of the bars and one attheir centers. The bolt heads are countersunk below the top surface of the plate 1 and the depression over the bolt head being filled level with the top of the surface with added metal by welding, as indicated at 5, and the weld being then ground and polished to produce a smooth surface uniform with the remainder of the plate. a
6 represents the front and rear bars of the structure, being angle-bars with their vertical flanges turned downwardly and their horizontal flanges turned inwardly. The bars 6 are stepped inwardly from the edge of the plate 1 so as to be within the .base B when the griddle is in place, the griddle being supported by the plate .1 which rests on the top of the base B and extends horizontally outside of the latter.
The bars 6 are held in place against the under side of the bars 2 and 3 by means of the end bolts 4 which extend through the bars 6, nuts 7 being screwed on said bolts up against the bars 6.
Between the bars 2 and 3, the horizontal flanges of the bars 6 are thickened upward- 1y, as by welding the metal strips 8 thereon, upon which thickened portions rest the ends of the heating elements or heaters D or the blanks D which may be substituted for certain of the heating elements when the degree of heat to be employed is less than that furnished by a full set of heating elements. The end portions ofsaid heaters are reduced in thickness from below, and there is a slight clearance or looseness of fit so that expansion is allowed for The shoulders 9 on the underside of the heaters clear the bars 6 sufficiently to permit longitudinal expansion without binding and they also prevent cu!!- tact between the electric terminals 10 of the heating elements and adjacent portions of the griddle structure should the heaters be misplaced relative thereto.
11 is a pressure plate which is attached to the bars 2 and 3 and bears upwardly on the heaters, thus insuring good terminal contact between the heaters and the top plate.
The plate 11 is sutficiently narrow to avoid contact with the terminals 10.
The three bolts 4". which extend through the centers of the bars 2 and 3 also extend through the plate 11 and the nuts 7 are screwed up against said plate.
12 represents bolts which secure the corners of the plate 11 to the bars 2 said bolts having their heads countersunk into the upper surfaces of the bars 2 to enable the top platelrtolfitflat on therbars and nuts 13 beingscreavedfup onsaid bolts 12 against the plate 11. i
- The plate 11 provides a thermal path to disseminate heatfrom the lowersides of-the heaters D a-nd'the b'a-rs 2 a-nd-3; a-nd frein the blanks or spacers D which may be Substituted for some of the heaters D.
