TOILET SEAT 2 Sheets-Sheet 2 Filed Aug. 1, 1945 Inventor 35 /05 y M/W Patented Aug. 24, 1948 UNITED STATES FATN'E' FFICE TOILET SEAT Edison William Conner, Detroit, Mich. Application August 1, 1945, Serial No. 608,262

1 Claim. 1

This invention relates to toilet seats of that type having an electrical heating or resistance coil incorporated therein, so that the seat may be heated and brought to an agreeable temperature.

The primar object of the present invention is to provide a toilet seat of the above kind which is comparatively simple in construction and may be expeditiously manufactured in an economical manner.

A more specific object of the invention is to provide simple and eflicient means for mounting the resistance or heating coil within and insulating the same from the toilet seat.

The exact nature of the present invention will become apparent from the following description when considered in connection with the accompanying drawings, in which:

Figure 1 is a top plan view of a toilet seat constructed in accordance with the present invention.

Figure 2 is a bottom plan View thereof.

Figure 3 is an enlarged transverse section taken on line 33 of Figure 1.

Figure 4 is a diagrammatic View of the heating or resistance coil.

Figure 5 is a view similar to Figure 1, of a modified form of the invention.

Figure 6 is an enlarged transverse section taken on line 6-5 of Figure 5.

Figure 7 is a fragmentary horizontal section through an end of the seat shown in Figure 5, drawn on an enlarged scale and taken substantially on the plane of line 1-1 of Figure 6.

Figure 8 is a diagrammatic view of the heating or resistance element, forming part of the construction shown in Figure 5.

Figure 9 is a view similar to Figure 3, showin a further modification.

Referring in detail to the drawings, the seat shown in Figures 1 to 4 inclusive is of the type embodying an endless ring having a rearward enlargement 5 to which are attached the usual hinges 5 for mounting the seat upon the closet in the usual manner. The seat proper comprises an inverted channel 1 of rounded cross section having an inwardly directly horizontal flange 3 along its edges, and a flat bottom plate 9 closing the channel at the bottom of the seat and marginally secured to the flange B by bolts [0 or the like. The seat may be made of any sanitary material, the inverted channel 7 being molded or pressed into shape. Mounted at suitable uniform intervals within the channel 1 is a series of vertically disposed insulator discs H having central openings l2 through which is threaded or strung a suitable heating or resistance coil l3 whose ends terminate at the back of the seat and enter a further insulator M mounted in the channel I. As shown, the insulator l4 may comprise the body of an attachment plug receptacle so that the heating coil may be connected with a source of current by the use of an ordinary attachment cord. Each insulator disc I! is provided with a peripheral groove as indicated at 15 to receive the intermediate portion of a U-bolt 15 whose ends extend through the outer wall of the channel I and has nuts I! adjustably threaded thereon. By adjusting the nuts H, the insulator discs may be adjusted to place the heating or resistance coil under tension, thereby maintaining all portions of said coil out of contact with the seat proper. The U-bolts preferably support the insulator discs in spaced relation to the walls of the seat, and it will thus be seen that the heating coil is eiiectively insulated from the seat proper. In practice, the heating coil is threaded through the insulator discs and the U-bolts are engaged in the peripheral grooves of said discs. This assembly is then inserted in the channel 8 and the U-bolts are effectively secured in place. The bottom plate 9 is then attached to the channel so as to complete the assembly, it of course being understood that the ends of the heating coil are first suitably connected with the insulator 0r receptacle l4. Obviously, the supply of current to the heating coil may be suitabl controlled, such as by means of a switch carried by the attachment cord used to connect the heating element with the source of current,

In the embodiment of Figures 5 to 8 inclusive, the seat is of the bifurcated type in which the seat is divided at the front as at iii. In this form, the channel la is of substantially C-shape in plan and is provided with the rearward enlargcment to intermediate its ends, which carrice the hinges 6a. Within each side portion of the channel 1a is mounted a series of uniformly spaced insulator discs Ila having peripheral grooves Ilia in which the intermediate portions of U-bolts Ilia are seated. The ends of the U- bolts lEa extend through the outer walls of the side portions of channel la and have nuts Ila adjustably threaded thereon, as with the form of Figure l. The heating coil in this embodiment consists of spaced portions l3a connected in series at It by means of a wire which extends through the coil portions l3a and may be suitably insulated from the latter. One coil portion 13a is located in each side portion of the channel la and threaded through the adjacent insulator discs Ha. At the front insulator disc of each side portion of the seat, the adjacent heating coil portion I 3a is anchored by passing the adjacent part of the wire l8 through a washer I9 that is disposed against the forward side of the foremost or forward insulator disc as shown in Figure 7. The ends of the heating coil are passed into a receptacle or insulator Ma at the back of the seat and mounted in the wall of the channel 7a, as with the form of Figure 1. Abottom plate 911 is provided for closing the bottom'of the inverted channel la, said plate 9a being flat and of substantially the same C-shape form in plan as the channel 1a. Channel 1a has the inturned flange 8a along its edges to which the plate 9a is marginally secured by bolting or the like at 10a. It will of course be understood-that ..the insulator discs II a are centrally apertured as at 1211 to have the portions of the heating coil threaded or strung therethrough.

As shown in Figure -9,-the U-bolts lfib'may be vertically disposed with their zends ,passing through the bottom; plate 917, thus' mounting :the heating coil 3h on said bottom" plate. for: removal with the latter from the channel "lb. .Inthis case,:the U'-bolts' will embrace the insulator .discs llb for sumcient'portions of their circumference to hold them in i the desired position.

.In use, the heating coil is simply energized by permitting and causing current to'flow therethrough, whereupon the coil effectively warms the seat2proper and:brings the;same to'an'agreeable temperature.

It will be seen that I-havetprovided 'a very simple and durable'heatedtoilet seat that may be expeditiously and economically manufactured and that will'insure long continued satisfactory service. The channelmember may be made'of suitable metal :or enameled ware butit-is preferably made of vari-colored substantially transparent or translucent plastic material.

What I claim is: A sanitary toilet seat comprising a casing composed of an inverted channel having an inwardly directed flange along its edges, a flat plate closing the channel at the bottom, and means passing through the margin of said plate and said flange for removably securing said plate to the channel, arseriesxof centrally apertured insulator discs "disposed in spaced relation within the channel, said insulator discs being provided with *peripheral grooves, U-bolts having their intermediate portions engaged in the grooves of the insulator discs and having nutted ends passing "through "a wall of the casing, said U-bolts removably supporting the insulator discs within the casing in a vertical position and in spaced relation to the walls of said casing, and a heating g0 coil strung through the centers of the insulator discs so as to be maintained-out of contact with the channeleand the plate, the ends of the U- boltsv passing .through the outer sidewall of the casingtoprovideforlateral adjustment of the insulator discs and-tensioning of the heating-coil.
