HINGE CONSTRUCTION FOR TOLET SEATS Filed Sept. 20, 1945 the bottom edge 3| of shelf 2 is a coil spring 39 covered at least in part by matching cups 40'.

From the above, it will be obvious that by the mere tightening of nut 30 on the threaded end 21 of shaft 26, the coil spring 32 will compress against the bottom edge of shelf 2, thereby applying tension to bolt 26 so as to force it down tightly against hinge pin 25, which is connected to seat 3. Pin 25 is thus forced tightly against the spaced walls 1 of hinge bracket 6, applying braking friction thereto. Because bracket l2 is pivoted freely on the outer end of pin 25, no braking action is applied to the cover by the tightening of nut 30.

Likewise, to apply frictional braking action to the cover 4, nut 38 is tightened on the screwthreaded lower end 36 of clamping bolt 35. It is again obvious that no braking action is h applied to seat 3 by the tightening of nut 38 because the hinge bracket I5 is pivoted to the free outer end of pivot pin 2 I.

By this 'novel construction and arrangement of parts, any desired amount of braking friction-can be applied to the pivotal connections of both the seat 3 and cover li, so asto control their movements from a horizontal to a vertical position. Thus, by tightening

nuts

30 and 38, such braking friction may be applied to the hinge or pivot pins 2| and 25 to hold the seat 3 and cover 4 against accidental movements, in the tilting position indicated by dotted lines in Fig. 1. v

and numerous. For instance, on ships,trains, or planes, lwhere the bowl is subjected to tilting movements, the desired amount of braking action may be applied to both the seat and cover so as -to prevent either one or both from accidentally falling from a vertical to a horizontal position and thus interfering with the user or one cleaning the bowl, f

While I have described a commercial form of my invention, it should be obvious that the same could be changed or modified withoutk departin from the spirit of the attached claims. v

What I claim is: I 1. A friction hinge construction for pivotally connecting a toilet seat andv cover to one another and -an underlying toilet bowl, said friction hinge construction comprising cooperating hinge brackets having aligned apertures and carriedone by the bowl and one by the seat, 4cooperating hinge brackets having aligned apertures and carried one by the bowl and the other by the cover,

a hinge pin lcarried-by the cover and extending through aligned apertures of the cooperating bowl and seat brackets, a hinge pin carried by i the seat and extending through the aligned apertures of the cooperating bowl and cover brackets, and friction braking means applied to the opposite hinge pins, whereby the frictional braking action applied to one hinge pin will control pivotal movements of the seat and the frictional braking action applied to the other hinge pin will control pivotal movements of the cover. v

2. A friction hinge construction for pivotally connecting a toilet seat and cover to onek another and an underlying toilet bowl having a rearwardly projecting supporting shelf, said friction hinge construction comprising .cooperating hinge brackets having aligned apertures and carried one by the bowl and one by the seat, cooperating hinge brackets having .aligned apertures and carried one by the bowl and the other by the cover, a hinge pin carried by the cover and extending through aligned apertures of the. cooperating bowl and` seat brackets,y a hinge p in carried by the seat and extending through the aligned apertures of the cooperating bowl and cover brackets, bolts extending through said supporting shelf and having hooked upper ends overlying said hinge pins, and tensioning devices on the lower ends of said bolts working agha'inst the underside of said supporting shelf, whereby the irictional engagement bet-Ween said hinge'pins'and cooperating hinge brackets may be varied to control the pivotal movements of said seat and cover.

3. A friction -hinge construction for pivotally connecting a toilet seat and cover to one another and an underlying toilet bowl having a rearwardly projecting supporting shelf, said friction hinge .construction comprising cooperating hinge :brackets having aligned apertures and carried one by thebowl andone by the seat, cooperating hinge brackets having yaligned apertures and l carried one by the bowl and the other by the cover,

` 30 The benefits of this arrangement are obvious a hinge pin carried by the cover and extending through aligned apertures of the cooperating bowl and seat brackets, a hinge pincarried by the seat and extending through the aligned apertures of the rcooperating bowl and cover brackets, clamping .bolts extending loosely through said supporting shelf and having hooked upper ends overlying said hinge pins at points adjacent the hinge brackets carried by said bowl, adjusting devices on the lower ends of said bolts working against the underside of said supporting shelf,l

whereby the frictional engagement between said hinge pins and cooperating hinge brackets may be varied to control the pivotal movements of said seat and cover, andspring means interposed between said adjusting device and said supporting shelf.

4. A friction hinge construction for pivotally` connecting a toilet seat and cover to one another and an underlying toilet bowl having a rearwardly projecting supporting shelf, said friction hingeconstruction comprising a pair of laterally spaced hinge brackets, each having spaced Walls providedwith aligned apertures and supported by and projecting upwardly from said` shelf, apertured hinge brackets carried by the seat and cover respectively and positioned adjacent opposite bowl supported brackets with their apertures aligned with those of their respective cooperating bowl supported brackets, hinge pins carried by the :cover and seat respectively and extending through the aligned apertures of opposite cooperating bracketsclamping bolts extending loosely through said supporting shelf and having hooked upperends overlying said hinge pins intermediate the walls of each of said rst men.

tioned hinge brackets, tensioning devices on the lower ends of said bolts working against the under side of said supporting shelf, whereby the frictional engagement between said hinge pins and said cooperating hinge brackets may be varied to control the pivotal movements of said seat and cover.

6..A.friction hinge :construction for pivotally connecting a toilet seat and cover to one another and an underlying toilet bowl, said friction hinge construction comprising spaced hinge brackets secured to the bowl, a hinge pintle carried by the seat and journalled for rotation. in one of the said hinge brackets, a hinge pintle carried by the cover and journalled for rotationin the other of saidspaced brackets, and friction braking means applied to the opposite pintles, Wherethe frictional braking action applied to one pintle will control movements of the seat and frictional braking action applied to the other of said pintles will control pivotal movements of t -e cover.

7. A friction hinge construction for independn ently connecting a toilet seat and cover to one another and to an underlying toilet bowl, said friction hinge construction comprising :coaxial hinge pintles located to the rear of the seat and cover and .adapted to be journalled to the toilet bowl, the seat being mounted fast on one of said pintles and tbe cover being mounted fast on the other thereof, and independent friction-braking means applied one to each of said hinge pintles, whereby the irictional braking action applied to one hinge pintle by its respective braking means will control pivotal movements of the seat and frictional braking action applied to the other hinge pintle by its respective braking means will control pivotal movements of the cover.

3. in combination with a toilet bowl, coamal Y:inge pintles horizontally disposed at the upper .rear portion of and journalled to the toilet bowl, a toilet seat having its rear portion mounted fast on one of the hinge pintles, a toilet cover having its rear portion mounted fast on the other of said hinge pintles, and independent friction braking means applied one to each of said hinge pintles,

whereby the frictional braking action applied to one hinge pintle by its respective braking means will control pivotal movements of the seat and frictional braking action applied to the other hinge pintle by its respective braking means will control pivotal movements of the cover.

9. In combination, a toilet bowl having a flange projecting from its rear portion, axially-spaced bearing brackets mounted on the shelf of said toilet bowl, coaxial hinge pintles pivotally mounted one in each of said bearing brackets, a seat anchored fast on one of said hinge pintles, a .cover anchored fast on another of said hinge pintles, anchoring bolts extending upwardly through the shelf of the bowl and through oppo site of the spaced bearing brackets and equipped with head-acting portions frictionally engaging the upper portions of the hinge pintles, and means on the opposite end of said anchoring bolts for yieldingly biasing the bolts in a downward direction.
