No. 294,035. Patented Feb. 26, 1884.

UNITED STATES PATENT OFFICE.

CHARLEs E. HART, OF NEW BRITAIN, CONNECTICUT, ASSIGNOB To THE sTANLEY WORKS, OF sAME PLACE.

SPECIFICATION forming part of Letters Patent No. 294,035, dated February 26, 1884.

Application filed June 7. 1881. llllodel.)

To all whom it may concern Be it known that I, OHARLEs E. HART, of New Britain, in the county of Hartford and State of Connecticut, have invented certain new and usefullmprovements in Strap-Hinges, of which the following is a specification.

My invention relates to improvements in strap-hinges. In my improved hinge the end of one leaf is provided with a coil to receive the pintle, which coil is nearly as long as the leaf is wide. The end of theother leaf is secured to a metal plate having flanges which bear the pintle.

In the accompanying drawings, Figure l is a front view of the said hinge, and Fig. 2 a top and edge view.

The main portion of the leaves A and B are substantially the same as in ordinary straphinges.

0 designates a plate or partial hingeleaf, having studs or rivets a a a a cast thereon, or otherwise formed integral therewith.

At each of the two side edges of the plate 0 flanges b b are formed, the same rising up and projecting from the front flat side of the plate 0, and also extending beyond the edge which is contiguous to the joint, said flanges also being formed integral with the plate. A pintle extends from one flange to the other, and I prefer to have the same cast in. The-leaf B, which has no knuckle or Coil, is provided with an offset, 6, which is near one edge of the plate 0. The offset end of said leaf is provided with holes to receive the studs a,which are riveted down or upset to secure the plate 0 and leaf I B together,while the offset 0 in said leaf brings the under side of the leaf and plate into the same plane, thereby adapting them to be securedto any flat surface,like an ordinary hinge. The leaf A has only one coil or knuckle, d, which is nearly as long as the leaf is wide, and which is coiled around the pintle, as shown. The hinge thus formed is but little, if any, more expensive than one with the ordinary joint, and is of superior strength, especially when used in exposed positions where the joint is liable to rust.

Iam aware that what may properly be called T-hinges have been made with a short leaf at one end,. with a pintle Cast in, and with a strap-leaf having its coil bent around the pintle,:md I hereby disclaim the same; also,tl1at a prior patent shows an ordinary three-knuckle strap-hinge with two flanged plates secured to the leaves thereof, and with the pintle passing through the flanges of said plates,which hinge is also disclaimed.

I claim as my invention The improved strap-hinge consisting of the flanged plate 0, bearing the pintle, the coilless strap-leaf B, secured to the body of said plate, said two parts forming one half of the hinge, and the strap-leaf A, coiled around the pintle and forming the other half of the hinge, substantially as described, and for the purpose specified.
