HINGE. t

SPECIFICATION forming part of Letters Patent No. 540,646, dated June 11, 1895. Application filed November 1, 18951. $erialN0. 527,606. (llomodeli) To all whom it may concern:

Be it known that I, WILLIAM B. DEMING, a

' citizenof the United States, residing at Bentonville, in the county of Benton and State of Arkansas, have invented certain new and useful Improvements in Hinges; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in strap hinges and has for its object the construction of a right angled re-inforcing plate of the class shown in Letters Patent No. 518,309, issued to me on the 17th day of April, 1894, but with an improvement in the construction whereby the plate after passing through the slotted leaf will follow the curvature of the knuckle a suitable distance before the bend is made, to bring the bent section of the plate in line with the verticalcenter of the hinge pin, in order to obviate the necessity of mortising the door jamb or post.

I accomplish the objects of the invention by the mechanism illustrated in the accompanying drawings, in which Figure l is a view in perspective of a straphinge securedto a door-jamb and provided with a reinforcing-plate made in accordance with this invention. Fig. 2 is a detail in horizontal section of a portion of the post and door, and showing the hinge and my reinforcingplate in top or plan view. Fig. 3 is a detail in side elevation of a portion of a hinge in which the reinforcing-plate in the part overlying the strap of the hinge is broadened to cover the full width of the strap and in which the plate is riveted to the hinge. Fig. 4:. is a detail in front view of a portion of a hinge, showing the enlarged slot through which the reinforcing-plate is passed; and Fig. 5 is a top or edge view of the reinforcing-plate detached from the hinge. 7

Similar letters refer to like parts throughout the several views of the drawings.

A represents the door jamb or gate post.

B and B are the two leaves of a strap hinge of common construction save that the space B (shown in Fig. 4:), is deepened to an amount equal to the thickness of a reinforcing plate which will be projected therethrough.

C, is the reinforcing plate above referred to and in the construction shown in Fig. 1, consists of a short bar of strap iron bent at a point about midway between its ends so as to form two plates which will stand approximately at right angles to each other. In the construction shown in my former patent, above referred to, the meeting ends of the two plates form a sharp corner which causes the plate which is thrust through the slot in the hinge to stand tangentially with relation to the knuckle of the hinge.

The longitudinal axis of the knuckle of a hinge when the hinge is properly applied, should be directly opposite the dividing line between the door and post, but where the plate as above described, is tangential to the knuckle it is necessary either to let the plate into the post by mortising, or else leave a wide space or crack between the post and the door.

In my present construction, instead of making a sharp corner at the junction of the two plates I make the inside curve 0 (Fig.5) conforming to the curvature of the knuckle and so proportioned as to align the platewith the axis of the pintle of the hinge instead of presenting it in a position tangential to the knuckle. By this construction, when the hinge is placed as it should be, with the vertical axis of theknuckle opposite the meeting line of the jamb or post, and the door, the plate C will be exactly opposite the meeting line. A neat job will thus be secured without mortising. This reinforcing plate may be sold as an attachment detached from the hinge or it may be permanently riveted, or secured in any other mechanical manner, to the hinge. The plate may also be formed as an integral portion of the leaf of the hinge in which case the right angled attaching plate will have an indented curved portion conmeeting it with the leaf. The part overlapping the hinge may be wide enough to cover the entire leaf or it may be of less dimensions.

Having thus fully described my invention, what I claim as new,-and wish to secure by Letters Patent of the United States, is-

1.- The combination, with. the pintle and leaves of a strap hinge, one of which leaves is cut away opposite to the knuckle or eye of the other leaf, so as to leave a slot when such knuckle or eye is placed in position, of a reinforcing piece bent to form two plates at right angles to each other of which one overlies the said cut away leaf and the other is adapted to pass through said slot, said two plates be ing connected by a section of the piece integral with the two plates but formed around the corner which otherwise would have been made by the junction of the two plates, and thereby affording an unobstructed space for the adjustment of the plates around the knuckle of the hinge whereby the knuckle will occupy the said corner space and whereby the plate passed through the slot will be aligned with the axis of the knuckle, substantially in the manner as described and for the purposes specified.
