FRlCTlON-HINGE.
SPECIFICATION forming part of Letters Patent No. 301,164, dated July 1, 1884.
Application filed January 23, 1884. (No model.) I
To all whom, it may concern:
Be it known that we, ROBERT S. RoBsoN and J OI-IN LOUGHREY, citizens of the United States, residing at Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Friction- Hinges or Supporting Devices for Mirrors,
' Transoms, &c., of which the following is a full, clear, and exact description, reference to being had to the accompanying drawings, making part of this specification, in which- Figure l is a plan of ourimproved friction hinge or supporting device. Fig. 2 is an enlarged vertical section of the same on the line w w of Fig. 1. Fig. 3 is a view of one of the leaves of the hinge and the pintle projecting therefrom. Fig. 4 is a vertical section thr'o ugh the other leaf of the hinge. Fig. 5 is a view of the spring detached.
Our invention relates to certain improvements in frictional hinges or supporting de vices, which are particularly adapted for supporting bureau mirrors, transom windows, swinging screens, &c., where it is desirable 2 5 to prevent the frame or article supported from oscillating too freely on its pivots; and our invention consists in a friction-hinge or's'upporting device for mirrors, transoms, 820., composed of two leaves'or portions, one provided with a circular orifice, with slightlyenlarged or countersunk ends for the reception of a pintle projecting from the other leaf, said pintle being flattened on one side to form a longitudinal recess for the reception of a curved spring, which is adapted to turn with the pintle and produce the desired friction between it and the walls of the orifice in which itis placed, while the opposite ends of the spring bear against shoulders at the ends of the recess of the pintle, and also fit closely into the countersunk ends of the orifice in which the pintle turns, thus securely locking the latter in place and preventing the separa tion of the two leaves of the hinge.
In the said drawings, A B represent the two leaves of our friction-hinge or supporting device, which may be made of any suitable form to adapt them for the purpose for which they are to be employed. These leaves 5 AB are connected together by a pintle, b, which is preferably cast in the same piece with the leaf A, but may be made separate and afterward cast within or otherwise immovably secured thereto. The leaf B is pro vided with an orifice, 0, extending entirely 5 through it from one end to the other, for the reception of the pintle I), each end of the orifice 0 being slightly enlarged or countersunk, as seen at (1, Figs. 2 and 4. That portion of the pintle b which lies within the orifice c is flattened or cut away on one side, as seen at e, forming between the shoulders f f a longitudinal recess, within which is placed a stiff spring, D, which is curved outwardly from the center toward each end 6, by which construction it is caused to take a bearing at three points only--viz., at the center of its length on the pintle b, and at each end,6,against the countersunk end of the orificecof the leaf B thus producing the desired amount of friction between the pintle and the walls of the orifice c, to prevent the mirror-frame, transom, or Y other article supported by the device from oscillating too freely on its pivots, and causing it to remain fixed at any angle in which it may be placed. The upper surface of the spring is curved or rounded transversely to correpond to the curvature of the walls of the orifice 0, thus preventing undue wear and it will be seen that the spring 1), which turns with the pintle b, besides producing the desired friction between the moving and stationary parts of the hinge, also serves to lock the pintle securely within the orifice c, as the opposite ends 6 of the spring lie partially below the level of the tops of the shoulders ff of the recess 6, against which they bear, and also fit snugly up into the enlarged or countersunk ends (1 of the orifice c, as seen in Fig. 2, thus preventing the easy withdrawal of the pintle 0 from the orifice c of the leaf B, and causing the two leaves to be securely held together as repintle and at each end against the countersunk ends of the orifice c, and having its ends partially below the level of the tops of the shoulders f f, substantially as and for the purpose described.
Witness our hands this 21st day of January, A. D. 1884.
ROBERT S. ROBSON. JOHN LOUGHREY.
In presence of- P. E. TESCHEMAOIIER, W. J. CAMBRIDGE.
