SANITARY TOILET SEAT.

Application filed December To all whom t may concern.' l

Be it known that I, Unrssns R. GRANT, citizen of the United States, residing at Alameda, in the county of Alameda and State of California, have invented certain `new and useful Improvements in Sanitary Toilet Sea-ts, of which the following is a specification.

The hereinafter described invention comprises a hollow sanitary toilet seat which is expressly designed for use in connection with hospitals, railway cars, and public places, although equally as well adapted for home use generally, and the object thereof is the production of a simple, light, sanitary and durable closet seat, one which will withstand the hard usage to which such devices are subjected, and will not warp, crack or become affected by reason of moisture or the water standing in the bow to which it is applied and by Vits construction will afford the user increased room at its forward under side over that afforded by the seats now universally in use. rlhe improved toilet seat is preferably constructed of two metallic sections or members suitably stamped to the proper shape, the upper member `of the seat having applied thereto an outer sanitary coating or "layer Yof hard rubber or other plastic compound. The plastic or rubber covering applied to the upper member of the seat affords a seal for precluding the entrance of`moisture between tlie unity. seam line of the upper and lower sections; gives a proper finish thereto, provides sufficient warmth to prevent undue chilling of the body of the user, and at the same time furnishes an antiseptic surface for the seat. The members c mpriving the seat are suitably stamped into proper shape for a toilet seat prior to the union thereof, the inn-er and outer edges of the lower section are upwardly flanged to receive on their inner faces the outwardly curved edges of the upper section.

To comprehend the invention, reference should be had to the accompanying sheets of drawings, wherein- Fig. l isa front elevation of a closet bowl with the improved seat applied thereto.

Fig. 2 is a bottom plan view of the seat removed from the closet bowl, disclosing the elastic cushions and their manner of attachment to the seat, and the raised pocket is, 192e. serial No. 681,354.

formed inthe forward portion, of the bottom member of the seat.

Fig. 3 is a plan view of the seat illustratdisposed arrow, particularly illustrating ther channeled recess at they under side of the forward edge of the seat.

The numeral l is used to designate any form of a toilet bowl to which the improved seat is hinged ;A 2 the bottom open member of the seat; 3 the upper open member thereof, and .et the layer or coating of hard rubber applied and vulcanized to the upper member 3. Preferably,l the bottom membery 2 yis stamped from a siiigle sheet of metal, Vand the upper member 3 similarly stamped from `a single piece of metal, the stamped members being of elliptical form. The upper memberr 3 when stamped is in the form' of a hollow elliptical shell, the upper surface thereof being gradually downwardly and inwardly curved from. the outer edge portionintermediate the points 5 and 6 to produce the required outline of a toilet seat, conformable to the body of a. user, the material between the points 5 and 6 being slightly VVcurved upwardly into substantially an ogee swell 6, the swell being sufficient to raisev the points 6a to a point above the normal Iplane of the remainder ofthe seat, the uprise caused thereby tending to properly place the user of the seat. The inner edge 6a, as in Fig. 5, is raised to a pointslightly below the normal plane of the upper surface of the seat while rthe outer edge on the same line y-fy is in the same plane with the remaining portion of the outer edge.

The said member 2 is from a point inwardly removed from its forward edge raised and curved upwardly and inwardly on the line 82 to provide a clearance space 8 to the under surface at such portion of the toilet seat. Y

The portion 83 of the member 2 lying forwardly of the space 8 lies in the same plane as the remainder of the member 2 and overlies the forward edge 84 of the closet bowl. The inner edge 9 and the outer edge 9 of the upper member 3 of the toilet seat are slightly i outwardly flanged, and the inner and outer edges l() and 10` of the bottom member upwardly flanged and crimped onto the flanged edges of the upper member when uniting one to the other. Y

While preference is given to a crimped seam. union between the inner and outer edges of the members of the toilet seat, it is obvious that the same may be united in any suitable manner.

hen the said upper and lower members are united, there is produced a hollow toiletseat composed of a substantially flat bottom and an upper metallic shell section, each of Vapproximately clliptical'forin, the exposed top surface of the upper member or section being shaped to conform to the outline of the body of a user thereof, and 'provided adjacent its forward edge with an uprise or swell. i

The upper elastic, plasticv or hard rubber `covering' l for the upper member-provides a comparatively warm and antiseptic covering surface for AVthe seat, one which removes the chill which otherwise would result from contact of the body with a metallic surface,

and at the same time provides a surface' which may be readily cleaned.

To the under face of the member 2 the upwardly curved arms `ll are united, within Vthefi'ee ends of which is mounted the transverse rod l2, which is supported and held by the hinge brackets 13by means o f which the toilet seat is hinged to the bowl 1 in the usual manner.

By reason of the seat being lformed hollowy there is secured extreme lightness, inasmuch as the members composing the seat may be constructed of thin metal.

The clearance space or depression 8 provided in the under face yof the bottom member of the toilet eliminates the danger of excess fouling adjacent the forward end portion thereof. i

There is provided a lid or swinging cover 14: `for use in connection withV the improved toilet seat, the samebeing united in any suitable manner to the hinge connection between the seat and the closet bowl. Like the seat proper, the swinging lid or cover lll is con* structed of stamped metal sheets properly provide a hollow substantially ellipticala pair of coopel* seat, one of said sections forming a bottom Y part of relatively wide liat form, said bottom part having an area of substantially semi-circular shape extending from the inner edge of the seat forwardly, said area extending upwardly in curved relation from the juncture with lthe fiat adjacent portion of the part, to the` central portion of said area at the inner edge thereof and terminating in a plane contiguous to the horizontal plane of the upper edge of the seat, and the other of said sections forming the. upper i part having the edge portions curved `downwardly from the central portion in a predetermined manner, the forwardportion of said upper part being formed with an area extending substantially `above the horizontal plane ofthe upper edge of the seat and spacedfabove the area of the bottom part, said last-mentioned area having the portion of greatest height adjacent the inner edge of the seat and having the remaining portions of the area curving downwardly in all directions into the curvature of the remaining portion of the part to provide abody receiving contour in said seat,v the edges of said sections being formed into interlocking cooperation to retain the sections in seat forming relation. y i t In testimony whereof I have signed my name to this specification.

ULYSSES R. GRANT.
