l"UNITED STATES PATENT OFFICE,

WILLIAM A. HENN AND MICHAEL D. HELFRICH, OF EVANSVILLE, INDIANA.

HINGE.

Specification of Letters Patent. Patented July 11, 1911.

Application led March 15, 1911. Serial No. 614,654.

To all whom "it may concern:

Be it known that we, WILLIAM A. I-InNN and MICHAEL D. HELFRICH, citizens of the United States, residing at Evansville, county of Vanderburg, and State of Indiana, have invented certain new and useful Improvements in'I-Iinges, of which the following is a specification.

This invention relates to hinges, and more particularly to those for watercloset seats and covers.

The present invention has for its object the provision of a hinge of the character set forth which will be of strong, neat and durable construction and so compact and peculiarly arranged that it will permit a closer roughing in or setting of the bowl and yet permit the seat and cover to stand in upright position, when raised, than has heretofore been possible.

IVith the foregoing object in view, we provide a hinge in which the leaf or fitting for the seat is provided with an eccentric hub with which coopera-tes a spring-actuated friction member so that when the seat is raised to any angle above approximately 45, it will be self-sustained, thus obviating accidental dropping of the seat with consequent damage thereto or to the bowl, and, further, the parts are arranged in a new manner in connection with the hinge post, which latter is peculiarly formed, as will more fully appear hereinafter.

In the accompanying drawings z-Figure 1 is a sectional elevation with certain parts in full lines; Fig. 2, a detail view showing the parts of one of the hinges and a part of the hinge for the cover in relative posit-ion, the hinge post being broken away; Fig. 3, a detail view showing the cam on the seat fitting; and Fig. 4l, a front elevation with the seat in section and broken away, the cover being raised.

The rear part 1 of the bowl is vertically apertured to accommodate the attaching bolts 2 for the hinge posts 8, the latter being provided with forwardly and upwardly extending parts t of tubular form provided with a bridge or web 5 and with ears 6 which have apertures 7. The hinge pintles 8 are received in the apertures 7 and are provided with collars 9 which are adapted to abut the innermost ears 6, said pintles being provided with a portion 8a loosely received in a socket 10, in each inst-ance, in the cover hinge 11 .to which the cover l2 iS Connected.

The cover 12 is, therefore, free to swing upand down and is not sustained in any position except when the seat is also raised.

The seat fittings 13 are secured to the under side of the seat 14 by screws 15 and have upwardly extending parts 16 each provided with an eye or aperture 17 through which the part 8b of the pintle loosely passes, and the parts 16 also have eccentric hubs 18 which are of such width that, with the member 16,they occupy the entire space between-the ears G of a given hinge post. A friction ring 19 receives the eccentric 18 snugly, yet easily, and has a stein 20, which is received in an aperture in the web 5, a coil spring 21 encircling said stem between the ring 19 and the said web and being of` such strength that the ring is held with considerable pressure in frictional engagement with the hubv 18.

The lid or cover 12 can be raised or lowered at willwithout disturbing the seat 16, as it is journaled on the ends 8a. When the seat is raised to an elevation of substantially 45 or greater, the eccentric hubs 18 have turned to such position that they so act with the frictionrings 19 as to insure retention of the seat and insure against liability of accidental dropping. Owing to the forward disposition of the hinge in relation to the bolt 2, due tothe construction of the post 11, the seat, and cover can be swung past the vertical position, even though the bowl is set very close to the wall, so that the employment of our hinge results in economy Vof space occupied by the bowl.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is :e

1. In a hinge, the combination of hinge members pivotally connected together and a spring-actuated friction ring having an eccentric connection with `one of said members.

2. In a hinge, the combination of hinge members pivotally connected together, one of which has an eccentric hub, and a spring actuated friction` ring receiving and engaging the said eccentric hub.

3. In a hinge, the combination with hinge members pivotally connected together, one of which has an eccentric hub, of a friction ring encircling said hub and provided with a stem, and a coil spring encircling the stem and frictionally holding the ring Vagainst the said hub.

4, The combination with a w-atercloset seat, of a hinge therefor, and spring-actuated means adapted for frictional coperation with the hinge members to thereby hold the seat in any desired raised position when elevated.

5. The combination With a Watercloset seat, of a hinge therefor having an eccentric, and means frictionally engaging the eccentric to hold the seat in raised position When elevated.

6. The combination with a Watercloset seat, of a hinge therefor having an eccentric,

and a spring-actuated brake member frictionally engaging the eccentric and adapted to hold the seat in raised position When 15 elevated.

In testimony whereof, We hereunto affix our signatures in presence of two Witnesses.
