TOILET SEAT Filed April l5, 1948 Patented Apr. 24, 1951 YUNITED STATES PATENT. OFFICE Albert Calderon, Atlanta, Ga.

Application April 15, 1948, Serial No. 21,111

jThis invention consists of anvimproved toilet seat and means or a device which has for its object three main purposes; 1) for facilitation of theA excretion of the waste from the human system; (2) for the saving of toilet paper; and (3) for sanitation.

An object is to provide an improved toilet seat which is simplification of the device and structure shown and described in my prior application for patent on Toilet Seat, Serial No. 19,272, .filed April 6, 1948, and more particularly with reference to the means for causing movable or slidable sections interposed in opposite sides ofthe seat, to be normally held in, in alignment with respect to the widths of said sides, and to slide .or shift outwardly under the weight of a person reposed on the seat in use, to cause the thighs and buttocks to be spread, separated or pulled apart and the area surrounding the rectum to be stretched when excreting fecal material, to facilitate and ease excretion of waste material so as to maintain said area or parts as well as the seat and bowl in clean and sanitary condition by reason of confining the excretion and saving on the use and expense of toilet paper.

Another object is to provide a toilet seat with slidable sections at the sides, adapted to move in and out on inclined planes, means being provided Ato normally cause the sections to move upwardly and inwardly on said planes to positions in alignment with the sides of the seat when the latter is not in use and said sections adapted to move outwardly and forwardly with respect to each side of the person using the seat to pull apart, spread or separate the thighs and buttocks and stretch the area surrounding the rectum thereby facilitating excretion of waste material and preventing contact ofthe fecal material with parts surrounding the rectum to retain the same clean and save toilet paper.

with the above and otherobjects in view, my Y 5 Claims. (Cl. li-2,37)`

Referring to the drawings, I0 designates a toilet seat of conventional character and any suitable durable material, having the bight portion I I attached at the back edge to a closet 4bowl in any desired manner, and provided witharcuate sides I2 terminating in spaced forward ends I3, so that the seat as shown'is of substantially horseshoe shape. The sides I2 of the seat I0 intermediately or at the points of greatest lateral curvature or projection are provided each with a transverse forwardly angled slot or recess I4 in its upper portion so that the two slots diverge forwardly in obtuse angled relation to each other to receive similarly related oppositely inwardly and outwardly slidable or movable top plates or sections I5 each provided with roughened, crisscross or corrugated top surfaces I6 so that surface friction with the thighs and buttocks of a person reposed or sitting on` and using the seat, is increased.

The front and rear ends of the slots, recesses or grooves I4 and the corresponding coacting and intertting ends of the sections I5 at each side,

are'parallel and extend diagonally entirely across the sides I2 from the inner edges to points adjacent or short of the outer edges thereof forwardly from the inside to the outside and said sections conform to the curvature, shape and plan of the portions of the sides I2 determined by the ends of the slots I4 and are concave on the inner edges and convex on the outer edges the same as sides I2.

rIhe slots I4 extend entirely across the thicknesses of sides I2 which as with the entire top face or surface of the seat Ill are generally convex as indicated at I6 and flat and on a horizontal plane at the bottom face or surface as at II including the base or bottom portions below slots incline generally outwardly, the longitudinal bottom inner portions or top surfaces I9 thereof for the lengths of the slots of less than half the width of the slots and seat sides, sloping from a point substantially intermediately of its height or thickness but preferably slightly below the halfway point being inclined downwardly toward the outside but terminating short of the trans-I verse center or less than half the wdthof the sides I2 or cross section thereof and terminating in a shallow or short vertical wall or surface forming an inwardly facing shoulder 29. From this point, the bottom of the slot I4 or top surface of the bottom wall thickness formed by the 5 slot, is inclined or sloped in an opposite direction or inwardly as at 2l, being elevated toward the outside and terminating in such direction by a similar but shallower short vertical wall or surface formingfl a second outer .inwardly` facing 10 shoulder 22 still slightly inwardly ofthe transverse centers of the sides I2 but medially to a vertical outer wall or surface 23 formed by a". vertical cut-out or recess 24 in the sides I2 at .the` outer ends of the slots I4. The top surfaces`25" 15 from walls or surfaces forming inwardly facing..- shoulders 22, incline or slope outwardly,to.outwardly facing vertical walls 23, iniinclinedplanes parallel to the inclined planes of the innerportions or surfaces I9 but oppositely at the oppositesidesIZ of theseat l0.

The sections I5. are similarly formed to. oppose thebottom portions-of sides I2 of .reduced .thickness where said sides are .provided with the slots I4, .that'is,v the :bottom portionsconstitute the. lower half portions or.. thicknesses. of thewall. portions ofithe sides I2 at .the.slotsl-.l4.integral with thef'remaining.portionsr'of the. seat,fw.hile. the plates orsectionsl 5fconstitute the upperhalf. portions orthicknesses of the wallpcrtions of. the sides I2.at.theslots:l4 therein. Thebottomsur.- faces ofthesection .I 5 have. outwardly sloping. or inclined inner .portions or .bottom .surfaces .25 iat the: inner portions of-.the sides.of.the seat of greatest thickness. or vertical. dimension, but. transversely or .cross.sectionally, surfaces 25 and thedepending .inner portionsof sections I5 forming thersame,Y are spaced...from,. parallel. ,tol` and. moreshallow, shorter or narrower transversely than the opposed similarly inclined top surfaces I9 and .terminate in outwardly.facingshallowor short vertical walls or surfaces forming shoulders 2l' opposing andparallel to wall surfaces or;stop. shoulders 2G." From the upper ends of shoulders 2l, inwardly inclined bottom surfaces 28 vare provided considerably spaced from, opposing 'and' parallel 'to .surfaces'2l butlocated normally ine wardly ofor in inner .vertical planes and higher horizontal planes and above same in offset or staggered relationwithrespect to'their inner and outerk ends or marginal limits extending diagonally as shown in Figure l.

4 parted from sections I5 or otherwise formed and attached thereto in any suitable manner as by screws 36.

Slidable sections I5 have pairs of inclined parallel end ribs 31 slidable in guideways or grooves 38 in the vertical Walls of slots I4 in which sections I5 are loosely received and move with a sliding fit, Anti-friction means are provided between sections I5 and the bottom portions of sides I2'formedby slots, recesses or 'grooves I4, and morev particularly between inclined surfaces I9 and 26, and 25 and 30, respectively. As shown, spaced parallel anti-friction cylinders or rollers 39.--are\ journaled at their ends or shafts in and carried by section I5 at semi-circular grooves llinsurfaces 26 to roll on surfaces'IS, or vice versa, andsimilarspaced parallel cylinders or rollers` 4I` are" journaled at the bottom walls formedby. slots I4, in semi-circular grooves 42 in surfaces 25, to roll againstsurfaces 30 or on which thelatter move, or vice versa.

In this way, sections l5 at opposite sides I2 -of the seat lareadapted tomove out and'down the inclines, and in andup same, in opposite directions. However, sections I5 are normally held .in and up or in raised positions alignedwith sides I2 as by any number of springs 43 .having their ends seated` inisockets or countersinks or'counterbores 44 to retain the springs in position toy normally move the sections inwardly, upwardly and rearwardlyand raise themin their guidewaysA or sliding mounts to positions inalignment'with sides I2 at slots I4.

Normally, a: person has to excretel the waste from his body twice' dailylandthese operations cause more or less-strain. Thisstrain which is detrimental and .unfavorable takes .one form or another, for example separating the thighs andv squeezing the stomach, or by pulling apart the buttocks with the handsrandat thesame time tioned discomforts. seat of horseshoe shape, the buttocks rest on Owing. to the weight of the person exerted on these sections or plates they will slide outward: because each of these plates rests on inclined planes built in the base of the seat. The cylindrical rollers facilitate the sliding of plates Ior sections.

countersinks 44 are used to bring back the sections or plates as soon as the Weight is removed"- from it. When a person sits on the seat, automatically the plates move outward and owing to people dirty not the rectum but the surrounding area of the rectum when eimretingv fecal material. Therefore; the surroundings stretched by th`e-present 'improved toiletv seat, are freed from contacting fecal material, thus saving toilet paper. lThe latter being true also accomplishes the second purpose of vthis device. The third purpose of the device, for sanitation, is accomplished vthroughthe elimination of the act of cleaning the surrounding area of the rectum. This device therefore is helpful inexcreting' the waste,` very sanitary' and most 'economical.`

Although the seat as shown inthe drawings is round or substantially round, the preferred form is substantially oval in shape; therefore, vit will The springs which are held in position by the two pairs ofv be understood that the shape can be either oval or round, but preferably oval.

Y I do not mean to confine myself to the exact details of construction herein disclosed but claim all variations falling within the purview of the appended claims.

What l claim is:

1. An improved toilet seat comprising a body having spaced apart side portions, upwardly opening transverse stepped slots formed in said side portions, the bottom surface of each of said slots being inclined outwardly and downwardly and including intermediate vertical portions, a separate seating section disposed in each of said slots and having a lower surface complementary to said bottom surface, and resilient means disposed between the vertical portions of said section and said slot and adapted to constantly urge said section inwardly and upwardly whereby said sections are normally disposed inwardly and upwardly and are moved outwardly and downwardly by the weight of a person positioned on said seat and said sections.

2. An improved toilet seat comprising a body having spaced apart side portions, an upwardly opening transverse stepped slot formed in the top of each of said side portions, the bottom surface of said slot being inclined downwardly and outwardly and including intermediate vertical portions, a movable seating section in each of said slots, the lower surface of each of said sections being complementary to said bottom surface and inclined downwardly and outwardly for slidable engagement with said slot bottom surface, resilient means disposed between the vertical portions of each of said slots and the associated movable section and adapted to constantly urge said section inwardly and upwardly, and means depending from said section adapted to engage said side portion for limiting the inward movement of said section.

3. An improved toilet seat as set forth in claim 2 wherein the front and rear walls of said slots are formed with elongated grooves therein extending parallel to said slot bottom surface, and said sections include flanges on the opposite ends thereof slidably engaging in said grooves to prevent removal of said sections from said slots.

4. An improved toilet seat as set forth in claim 2, wherein anti-friction means are disposed between said section bottom surface and said slot bottom surface.

5. An improved toilet seat comprising a body having spaced apart side portions, a transverse upwardly opening slot formed in each of said side portions, a movable section disposed in said slot, said slot and said section being formed with stepped outwardly and downwardly inclined slidably confronting bottom surfaces, the steps of said bottom surfaces being adapted to abut each other for limiting the outward motion of said section, spring means interposed between said steps for constantly urging said section inwardly and upwardly, and means depending from said section and adapted to engage said side portion for limiting the inward motion of said section.
