HINGE FOR WATER-CLOSET SEATS.

Specification of Letters Patent.

Patented Feb. 16, 1915.

Application filed November 14, 1913. Serial No. 800,897.

To all whom it may concern Be it known that I, PAUL SH'WAB, a citizen of the United States, a resident of the city of Jersey City, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in Hinges for Water-ClosetSeats, of which the following is the specification.

This invention has for its object the production of a seat that will automatically lift and be retained in an upright position when not required for use, and although applicant is aware that devices of this kind or having these functions have been known to exist, most of the well-known self-raising seats are provided with cumbersome weights, or if a spring is employed, the mechanism is rather complicated. --Applicant has endeavored to remove all complications, to make all parts exposed and easily repaired and to make any part that may bebroken cheap in replacement.

The advantages and details of construction of this device will be fully set forth as the specification progresses.

The following is what I consider the best means of carrying out this invention, and the accompanying drawings form a part of this specification, in which Figure 1, is a bottom plan view of the seat and shows the arrangement of the parts when the seat is raised. Fig. 2, shows the seat depressed, this view is in perspective and shows the position of the separate parts. Fig. 3, is a side elevation partly in section of the device as shown in Fig. 2. Fig. 4, shows a modification. Fig. 5, shows certain of the modified parts removed.

Similar reference numerals indicate like parts in all the figures where they appear.

At 1, I have shown a seat of ordinary construction shape and design, but without the cover that usually is to be found hingedly attached to the seat. At 2 and 3, the usual hinge posts are shown that are of a sufficient length to pass through and tobe secured to the basin or bowl. Extending between the posts 2 and 3 and secured therein by means of set screws 4 and 5, I have arranged a shaft or rod 6. This rod should be round and of a sufiicient size to reliably support all of the parts that will be secured to it. Arranged upon the rod 6 and at certain distances apart, are hinge leaves 7 and 8 which extend under and are secured to the seat by screws or by any other suitable means.

Each of these hinge leaves 7 and 8 is provided with an upwardly extending post as shown at 9 and 10 respectively and as the operation of the hinge leaves must be ac companied by a relative motion of the posts 9 and 10, I prefer that the posts and hinges shall in each instance be formed integral. The hinge leaves and posts are free to revolve upon the shaft 6, to any desired ex tent.

Secured to the shaft 6 and at about midway between the hinge leaves, I arrange a block 11 which is a clamp into which the spring 12 is secured. The spring 12 may be a strip or leaf spring secured at its lower end to the block 11 as described and at its upper end being provided with a perforation through which a suitable rivet or screw 13 may pass.

Arranged at right-angles to the spring 12 and secured thereto by means of the screw or rivet is a second spring 14, which may be a strlp spring or may be provided with a plurality of leaves as shown. This springv 14 extends outward past the posts 9 and 10, and has its outer ends more or less firmly secured to collars or guides 15 and 16 arranged upon the posts 9 and 10. These collars 15 and 16 are free to move longitudinally upon the posts 9 and 10 and are also free to rotate thereon to an extent that will be determined by the motion of the spring 14.

The operation of this hinge may be readily understood from the foregoing description, but it will be observed that when the seat is depressed, the posts 9 and 10 moved by the hinge leaves 7 and 8, will carry forward the ends of the spring 14 and the upper end of the spring 12. Now when the pressure is removed from the seat, the springs will return to their normal fiat and straight position and the seat will be raised to a Vertical position as shown in Fig. 1. I have taken care that the location and dimensions of all of the parts shall be such as to allow an easy operation of the seat and a positive return to the vertical position without undue strain upon the springs or upon any of the supporting parts thereof.

In Fig. 4, I have shown a modification wherein the spring is a coiled spring, both ends of which terminate under the seat as shown at 21 and 22. This spring indicated at 20, has a loop 23 formed at about mid-length and a clamp somewhat similar to the clamp 11 as shown at 24 engages the loop 23, and by virtue of its secure position 4 upon the shaft 6 assists in obtaining the proper tension in the spring; I have, however, discovered that the clamp 24: may be omitted and a hook 25 as shown in Fig, 5 may be substituted therefor. This; hook may be screw-threaded and I would then produce a screw-threaded hole 26 in the shaft 27 to accommodate the hook 25.

"Other means may be employed for securing the ends of the shaft 6' and other modifications may be made within the scope of the appended claims, but I prefer the whole as shownand described. 7

Having carefully and fully described my invention what I claim and desire to secure by Letters Patent; 'i's A device of "the --character described comprising a plurality of hinge leaves pro vided with extensions, a bar extending through said hinge leaves, a spring upon said bar and a block for securing said spring in operable position upon said bar, said spring being provided with flexible extensions-adapted t'o engagethe extensions from said hinge leaves as herein specified.

2; A wa ter closet seat having a plurality of posts a shaft between said posts, hinge leaves upon said shaft, provided with extensions; spring secured to said] shaft, and an additional spring" arranged between said extensions asherein specified and for the purpose set forth.

3'. A water-closet seat having a plurality of posts, a shaft between said posts, hinge leaves upon said shaft, extensions from said hinges, movable collars upon said extenslons, a sprlng secured to sald shaft, an additional spring secured to said movable colsaid hingeleaves, and a block upon said shaft secured to one of said springs in combination with an ordinary water-closet seat and supporting posts therefor, as herein specified.

Signed in the city, county and State of New York, this 29th day of October, 1913.

I v PAUL SHWAB.
