PIVOTAL SUPPORT FOR MIRRORS TRANSOMS, 80C.

SPECIFICATION forming part of Letters Patent No. 341,636, dated May 11, 1886.

Application filed February 26, 1886. Serial No. 193,339. (No model.)

To all whom it may concern:

Be it known that I, OSCAR PAUL BREITHUI, of Villiamsport, in the county of Lycoming and State of Pennsylvania, have invented a new and useful Improvement in Pivotal Supports for Mirrors, Trausoms, &c., of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which Figure lis a front elevation, partly in section, showing the application of my improved support to a mirror-frame. elevation showing a different method of applying the same support to a mirror-frame. Figs. 3, 4', and 5 are side elevations of difl'erent forms of pintle-support. Fig. 6 is a side elevation of the half of the support containing the pintle. Fig. 7 is a front elevation showing one form of my improved support, partly in section.

Similar letters of reference indicate corresponding parts in the different figures of the drawings.

The object of my invention is to provide an improved support for tilting mirrors, transomlights, and doors designed to remain in the position in which they are placed.

My invention consists in a hinge formed of three partsa conical pintle, a socket adapted to receive the conical pintle, and a support for the projecting end of the pintle, the conical pintle being held in frictional contact with its socket, so that when the pintle is turned in its socket, or the socket is turned on the pintle, they will be retained in position by friction. The socket A is bored conically to receive the conical end of the pintle B, and is provided with apertured cars a, for receiving the screws by which the socket is secured to the mirror or its frame. The conical pintle B is secured in the socket A by riveting its smaller end down upon the socket, as shown in Figs. land 2, or by means of a screw inserted into the smaller end of the conical pintle and pressing upon a washer, Z), resting against the side of thesocket A.

As there are various ways of securing the pintle B in the socket A, I do not limit or confine myself to any particular method. The larger end of the conical pintle B is squared,

Fig. 2 is a front forming a shank, c, which is fitted to a sup port, 0, secured to the mirror-frame or mirror. The support 0 is formed of a base-plate, d, and an arm, 6, projecting from the plate at right angles and bent upward parallel with v the plate, as shown in Fig. 3. The plate (I is apertured to receive screws by which the support is held in position for use.

There are two methods of applying my improved hinge to a mirror or transom window, which are shown in Figs. 1 and 2. In Fig. l the socket A is secured to the mirror-frame D, and the supportC is secured to the uprights f, which support the mirror. The shank c of the conical pintle B rests upon the arm e, and is received between the upwardly-bent part of the arm and the base-plate (1. I11 Fig. 2 the hinge is reversed, the socket A being secured to the uprightsf, and the support 0 being attached to the mirror frame D and hooked over the squared end of the pintle B.

Instead of forming the support 0 of a baseplate and an arm, as above described, I may make it of a plate, offset or bent. twice at right angles, to form, in connection with the surface to which it is applied, a hearing for the squared end of the pintle. In some instances I bore the shank 0 transversely, and provide an angleplate, 71, having a pin, i, adapted to be received in the aperture of the shank, as shown in Fig. 5. Then the shanks of the piutles B are held against turning, as in Fig. 1, and the socketsA are turned thereon by the turning of the mirror or transom, the friction between the socket and the pintle will be sufficient to hold the transom or mirror in any position in which it may be placed, and the same result will be secured when the socket is held stationary and the pintle revolved thereon by the turning of the mirror or transom, as shown in Fig. 2.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a pivotal support for mirrors, transoms, &c., the combination of the conicallybored socket A, the conical pintle B, fitted to the socket, and means for supporting the pintle, substantially as herein shown and described.

2. As an improved article of manufacture, arm, 0, substantially as herein shown and Ge a pivotal support for mirrors, transoms, 8m, scribed. formed of a conic-ally -bored socket, A, provided with apertured ears a, a conical pintle, OSCAR PAUL BREITHUT' 5 B, secured movably in the socket and having \Vitnesses:
