Serial No. 567,833.

This invention relates to hinge connections for members to be pivotally connected to other members and is particularly adapted in mounting seats and covers therefor on water closet hoppers.

The invention consists of novel means for attaching the hinge plates to the seats and covers, the object being to rigidly secure these plates in position without the use of screws or similar elements.

This object is attained by the mechanism shown in the accompanying drawings.

For the purpose of illustrating the invention, one preferred form thereof is illustrated in the drawings, this form having been found to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized, and the invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described except as required by the scope of the appended claims.

Of the drawings Figure 1 represents a plan of a water closet hopper having cover and seat attached thereto by hinge connections embodying the principles of the present invention.

Figure 2 represents a side elevation of same.

Figure 3 represents a rear elevation of same drawn to an enlarged scale with portions thereof in section.

Figure 4 represents a side elevation of one of the hinge connections and its support and showing the cover closed.

Figure 8 represents an elevation of one 1 of the hinge members showing the inner face thereof. Figure 9 represents a side elevation of the support for said hinge member.

Figure 10 represents a section through a portion of the seat and showing means for securing an insulated trunnion thereon.

a Figure 11representsayvertical transverse securedthereto by a tubular member.

Figure 12 represents a horizontal trans verse section showing means for mounting the two-part se'at upon the supports without a cover.

Figure 13 represents a vertical transverse section of, a one-part seat and cover showing the end plates provided with hubs extending into sockets in the seat.

Figure .14 represents an elevation of'the inner face of anend plate provided with a seat engaging stud, and

Figure represents an elevation of the inner face of an end plate used in connection with the seat when no cover is used.

Similar characters indicate like parts throughout the several figures of the .drawmgs.

In the drawings, 10 is a portion of water closet hopper having a flange 11 to which posts 12 are securedinthe usual manner by nuts 13 threaded to shanks 14 extending through the flange 11. r I

The upper end ofeach post 12 is preferably curved forwardly and is provided at its upper end with an opening 15 into which extends a cylindrical hub 16 formed upon anend plate 17, each hub being pro vided with a cylindrical socket 161 at its inner end.

The hubs 16 of the end plates 17 are prevented from being displaced from the supports 12 by means to be hereinafter described. g The upper end of eachplate 17 has a forward extension 18 and on the inner face of each member 17 and extension 18 are two cylindrical lugs 19 whichareadapted to extend into cylindrical holes formed in a rear ward extension 20 forming part of acover Each end plate 17 is provided on its inner face with a semi-annular rib '22, the lower end of which is adapted to abut the forward side of one of-the posts 12 when the cover is in horizontal position, as shown in Fig. 4:, while the opposite end of said rib 22 is adapted to abut the rear of said post 12 when the cover 21 is in raised position, as indicated in Fig. 5.

In each socket 1600 is a collar 17w surrounding the outer end of a cylindrical metal rod 23 which accurately fits a cylindrical hole 23% extending transversely of a rearward extension 24, forming a portion of a two-part seat 25, open at the front and rear, as shown in Figs. 1 and 3. v

Thedistances between the'outer side faces of the extensions 24 is less than the distance between the outer side faces of the extension 20, so that in looking down upon the top of the seat 21 the extensions 24 are not exposed to view..

Between the two extensions 24 is a tubular member 26 of insulating material which retains the two extensions 24 properly spaced apart.

Between these two extensions 24 and in front of the tubular member 26 is a tube 27 of the same length as tubular member 26 and through which extends a metal rod 28, the opposite ends of which are tapered and provided with right hand threads as at 29.

The inner ends of the metal rods 23 are tapered, as at 30, and in contact before these rods are forced towards each other, while their outer ends are upset over the outer ends of the collars 17 w which serve as trunnions for the seat 25.

The holes 2300 serve as guides for the rods 23 so that the tapered ends of these rods will always meet accurately within the tubu- 'lar member 26, substantially midway of its length.

The holes 2300 are first formed in the extensions 24 and. then the rods 23 with the collars or trunnions 17m mounted on the outer ends thereof are forced into these holes 23m under pressure.

At the same time that these rods 23 are being forced inwardly with their tapered ends 30 contacting, an electric current is passed through the rods 23 causing said innor ends 30 thereof to be welded together so that the trunnions 179: are permanently secured in position and cannot be separated from said seat 25. v

Preferably a washer 3000 is positioned between each trunnion 17aa and the outer side wall of extension 24 to prevent said side wall from contacting with any portion of the end plate 17 or support 12.

The threaded ends 29 of the rod 28 are so positioned in the extensions 24 of the seat that the inner faces of the extensions 24 will bear firmly against the opposite ends of the tube 2'T. Y

hen the metal rods 23 have been welded together with the inner walls of the extensions 24 bearing against the opposite ends of the tubular member 26, the separation of said extensions Willbe effectually. prevented and the trunnions 1700 will be rigidly held against the washers 3000 so that they cannot turn relatively to the rods 23.

lVhen this has been accomplished the two parts of the seat 25 are rigidly held together and cannot spread apart, move inwardly or assume inclined positions relatively to each other. When the inner ends of the rods 23 are thus connected together, it is impossible for the cylindrical trunnions 1702 forming a pivot for the seat 25 to be displaced.

One set of lugs 19 oppositely disposed on the end plates 17 have metal rods 19m extending inwardly therefrom into a hole extending transversely of the extension 20 of the cover 21.

The inner ends of these rods 1900 are tapered and in contact before pressure is applied to force them toward each other.

hen such pressure is applied and an electric current is passed therethrough, the tapered ends will be welded together so that it is impossible to separate them and consequently the hubs 16 of the end plates 17 cannot become dislodged from the cylindrical bearings 15 in the supports 12.

The hubs 16 form the pivot for the cover 21 to turn on and the trunnions 1706 form the pivot for the seat 25 to turn on.

g It will be noted that the axes of the trunnions 17m and hubs 16 are coincident so that when the seat 25 and cover 21 are, both raised there can be no movement of one relatively to the other and consequently all chafing is avoided which is a great advantage'as such chafing will-mar the material enveloping the seat 25 and cover 21 and make them unsightly. V 7

There are two distinct operations of weld ing in the assembling of the seat 25 and cover 21 on the supports 12, the first being the welding together of the rods 23 to secure the trunnions 17m to the seat and the next being to secure the end plates 17 in position by welding together the rods 19% in the cover 21.

' To prevent short circuiting in the rods 23 when the rods 19% are being welded together one of the trunnions 17% is surrounded by a collar 31 of insulating material and preferably a paper disk 32 is placed between the trunnion 17m and the washer 3050, as indicated in Fig. 10. I

To further insure against short circuiting it is desirable to have an air space 33 between the outer end of the trunnions 17m and the inner ends of the sockets 1629 as shown in Fig. 7.

By this construction theuse ofscrews and similar instrumentalities is dispensed with and the outer faces of the end plates 17 are smooth and unbroken, thus leaving no depressionsin which foreign substances may lodge.

As before stated, the rearward movement of the cover 21 when in its raised position is limited by the rearward end of the ribs 22 coming into contact with the posts 12.

By this construction of hinge connection, said hinge connections may be secured to the cover 21 or seat 25-or to both the cover 21 and seat 25 after said. cover 21 and seat 25 have been enveloped with-sheets of celluloid or other material without any danger of injury thereto.

In some cases, it is desirable to dispense with the cover 21 and pivot the two-part seat 25 directly upon the posts 12, in which case the upward extensions 18 of the end plates 17 are dispensed with, and an end plate 34 is used, such for instance as that shown in Fig. 15, in which case the rods 23 are secured directly to the hubs 34a: of said end plates 34 and lugs 35 are provided which extend into the seat 25.

This construction is shown in Fig. 12.

In this particular construction just described thehubs 34m extend into the openings 15 in the posts 12 and each plate 34 is provided with stop shoulders 22a; to coact with posts 12 to limit the movement of the seat in either direction. i

In some cases headed collars 36 are disposed in the outer face of the extensions 24 as shown in Fig. 13, the outer ends of these collars extending slightly beyond the outer faces of the extensions 24 into contact with the inner faces of the supports '12, thereby leaving a slight space between the inner faces of the posts 12 and the outer faces of the extensions124. i V

In this construction the end plates 17 are secured in position by welding together the rods 19m in the cover and said end plates 17 have studs 37 extending therefrom through the posts 12 andinto the collars 36.

In the several constructions shown and described, all rubbing against the outer face of the extension 24 is obviated when the seat 25 is raised or lowered.

This is of some consequence as the seat is usually covered with celluloid or similar material and if chafed becomes unsightly.

In some cases the trunnings 1750 may be secured to the seat by a hollow rod 38 extending through seat 25 and trunnions 17m and upset at its opposite ends, as shown in Fig. 11.

By mounting the seat and cover on a water closet hopper by such hinge connections as herein shown and described, a perfectly sanitary construction is provided which has great strength and the elements are permanently retained in position. a

By this construction the use of all screws and similar instrumentalities is entirely disof the hinge connections to getvout of commission.

The construction herein shown and described is particularly adapted for use in rear.

Thestop rib 22 surroundsand .is slightly separated from the periphery ofthe semiannular ends39 :of the posts 12.

The end plates 17 with the rib 22 hide from View the greater part of the. posts 12 when the cover 21 is either in raised or lowered position.-- v
