Application November 6, 1946, Serial No. 708,161
4 Claims.
My invention relates to electric broilers, and i more particularly to the heating units in the top thereof, and one object is to provide a unit of the above character which contains means for quickly and securely fastening it to the broiler top.
Another object is to provide an installation wherein the heating unit is removably attachable, whereby to save time in installing or removing the same.
A still further object is to provide a handy control in the center of the broiler for securing the said unit in place.
An important object is to design the invention along lines of economy and simplicity.
With the above objects in View, and any others which may suggest themselves from the description to follow, a better understanding of the invention may be had by reference to the accompanying drawing, in which:
Fig. 1 is an inverted view of the broiler top, showing the installation of the improved heating unit;
Fig. 2 is a section on the line 2-2 of Fig. 1;
Fig, 3 is an enlargement of the central portion of Fig. 1; and
Figs. 4 and 5 are, respectively, sections on the lines 4-4 and 5-5 of Fig. 3.
In accordance with the foregoing, specific reference to the drawing indicates the typical domed top of the broiler at Ill, and the terminal plate for the electric current connections thereto at H. The array of heat elements I2 for the top H] is carried by a base plate l3 which is disposed inside the top Iii. formed with a set of posts M on the inside constituting extreme limits for the insertion of the plate l3.
While the terminal plate ll suffices to anchor the plate I3 to the top H] at one side, an additional support must be provided for the latter plate. Thus, the same is formed with an elon gated slot 15 at the center, which allows access to a central post 16. The latter is tapped for the insertion of the threaded shank ll of a thumbscrew l8 directed from the outside of the plate l3.
Ordinarily, the thumbscrew forms a stop against the falling of the plate l3 away from the top it! when the head 18 of the thumbscrew is turned away from the course of the slot l5, as shown in Figs. 3 and 4. However, I have found that the sheet metal material of the plate l3 yields to the pressure of the thumbscrew head after some time, so that the plate becomes loose The latter is of cast metal and is in relation to the thumbscrew and the top in.
I have therefore devised a means to correct this situation.
It is noted in Figs. 3 to 5 that the plate I3 is formed with a cluster of radial indentations H9 in the region of the slot I5. These are designed to form pockets for the head l8 of the thumbscrew, pairs of the indentations being aligned for this :purpose. Thus, after the indentations at any point have begun to yield to the pressure of the thumbscrew head after some time, it is an easy matter to give the thumbscrew a partial turn in a clockwise or advancing direction, as seen in Fig. 3, until the said head seats in the next pair of indentations. The threaded relation procures the advance of the head id in respect to the plate 13 With a progressive grip on the same. It may be mentioned here that the plate [3 ordinarily seats in the curving sides of the top II] with all or parts of its edge, but in the event that the top is only a partial support for the plate, the latter eventually meets some or all of the posts I l and It to secure a firm support in several places.
It will be evident that the plate l3 disposed in the manner described above may be quickly set into the broiler top H) by merely turning the thumbscrew head l8 to the transverse position indicated by finely-dotted lines in Fig. 3. Thus, when the plate has been set in place, a partial turn of the thumbscrew to the position shown by full lines firmly secures the plate in position. Conversely, a backturn of the thumbscrew to the original position enables the plate l3 to swing clear of the top in or to be removed from the same by the disconnection of the terminal plate II. An installation is thus had which not only facilitates the faster production of the broiler, but enables repairs to the same to be made quickly because of the easily removable feature of the heating unit. Finally, it is apparent that the improvement does not complicate the broiler to any extent but is of a simple construction and neat form.
I claim:
l. A structure for securing a plate in the hollow of a vessel comprising a support directed from the bottom of the vessel toward the plate, the latter having an elongated slot opposite the support, and means for retaining the plate to the support comprising a thumbscrew directed through the slot to thread into said support, the head of the thumbscrew engaging the plate from the outer. side when turned away from the slot, and means to lock said head from rotation.

3. A structure for securing a plate in the hollow of a vessel comprising a support directed from the bottom of the vessel toward the plate,.the latter having an elongated slot opposite the sup= port, and means for retaining the plate to-the; support comprising a thumbscrew directed through the slot to thread into said" support, the" head of the thumbscrew engaging the platexfrom the outer side when turned away from the slot,
