ADJUSTABLE HINGE.

SPECIFICATION forming part of Letters Patent No. 61 1,468, dated September 27, 1898. Application filed March 29, 1898. Serial No. 675,532. (No model.)

T0 at whom zit may concern:

Be it known that I, CHARLES M. ELKINs, a citizen of the United States, residing at Wakefield, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Butt-Hinges, of which the following is a specification.

The object of this invention is to provide an adjustable butt-hinge for doors in order to prevent them from binding at the j amb by reason of swelling of the wood or otherwise. I'Ieretofore if a door was set too close to the jamb or if the butts were not accurately located it was necessary to plane off a part of the door or the casing or to remove the door from its hinges and the butt from the casing, plug up the old screw-holes and form new ones, and then replace the butt, with no certainty that the door would then hang properly.

By my improvement, without removing the door from its hinges or marring the paint or wooden surfaces, the desired adjustment of the door with relation to the jamb may be readily effected. This is accomplished by means of the novel construction of the butt giving adjustability to its parts, as will now 'be described.

The peculiarity of the device is that the leaf of the butt which is securedtothe door-casing is made in two sections or parallel members, one sliding upon or with relation to the other. The part or member permanently fixed to the casing has top and bottom horizontal flanges, forming ways for the movement of the other member, and also a transverse central opening, with a projecting perforated lugat each end thereof, through which a screw passes, the lugs not being internally threaded. The sliding member of the butt has a central hub or protuberance extending through the transverse opening in the fixed member and internally threaded to receive the screw which passes through the unthreaded perforations of the two lugs, such screw being headed at each end in the outer face of said lugs, so that it cannot move lengthwise. Hence when the screw is turned by a screwdriver applied to its nicked head its rotation gives a movement forward or back to the sliding member having such threaded hub and of which the socket which receives the pintle of the hinge is also a part. It follows that turning the screw will move the door on its hinge nearer to or farther from the jamb and ease it where too snug or tighten it where too loose, and also that one or other of the hinges maybe thus adjusted,as desired, without in any case removing the door from its hinges.

In thedrawings, Figure 1 is an elevation of part of an opened door and its casing connected by my improved butt or hinge. Fig. 2 is a view of the same parts in elevation, showing theirposition when the door is closed. Fig. 3 is a horizontal section on line 3 3 of Fig. 2. Figs. 4:, 5, and 6 are respectively front, edge, and back views of the duplex leaf or member of the butt by-which adj ustability of the door is attained; and Fig. 7 represents the several parts of the butt detached.

A represents the door, B the edge of the door-casing to which the hinges are secured, and O the jamb or part of the casing against which the face of the door abuts when closed.

D is one member of the hinge, fixed in the edge of the doorflush with the surface of the wood and having'the usual pintle d to enter the vertical socket of. the duplex member of the hinge mounted adjustably on the casing. This duplex member comprises the portion E, formed with rearwardly-extending lugs E at each end of a central opening F. and with top and bottom flanges e parallel to each other and extending forward to serve as ways for the sliding movement of the adjustable portion. This adjustable part of the duplex member consists of the fiat body F, having at one edge the vertical socket f for the hinge-pintle d and on the back an internallythreaded protuberance F, extending through and somewhat shorter than the opening E between the lugs E. These lugs have unthreaded perforations in line with the axis of the screw-thread in the protuberance F, and a screw G, threaded only along its central portion, passes through the alined lugs and protuberance and is providedat each end witha head G, abutting against the outer face of the lugs. Hence this screw cannot move lengthwise; but when rotated its central threads, engaging in the threaded hub or protuberance F, move the sliding part F, having the socket f, and consequently carry the door A toward or from the jamb O. The

fixed portion E of the duplex member of the hinge is secured to the casing B by screws H, which are inserted and removed through corresponding but enlarged holes h in the sliding part F.

The construction may be somewhat modified without departing from the spirit of my invention, Thus the top and bottom flanges e may be dovetailed or be formed on the sliding part instead of the fixed part of the butt, or they may be omitted and the protuberance F have a bearing for its slight and infrequent movement on the sides of the opening E I claim as my invention- 1. A butt-hinge having one duplex member comprising a fixed portion having a transverse central opening and rigid lugs with unthreaded perforations in alinement at the ends of such opening, and a sliding portion formed with a rearward protuberance extending through said opening and internally threaded in line with the perforations .in said lugs, in combination with a screw engaging centrally in said threaded protuberance, turning freely in said lugs and headed at each end to prevent longitudinal movement, substantially as set forth.

2. In a butt-hinge, a duplex member consisting of a fixed portion with a transverse central opening, rearward lugs at the ends of said opening and forwardly-extending terminal flanges, in combination with a sliding portion fitting the face and between the flanges of the fixed part and havinga threaded hub or protuberance working within and of less length than said opening, and with an adjusting screw engaging Within said protuberance, passing through perforations in said lugs and headed at each end, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

CHARLES M. ELKINS.
