William B. Hunt, Montgomery, Ala.

Application March 2,

2 Claims.

This invention relates to improvements in hinges.

In the mounting of certain doors, notably automobile doors, it is necessary not only to hinge the door but to provide a resilient bumper means which is so placed as to be put under compression as the door is closed in order to prevent the door from rattling. This bumper must also be adjustable in some manner in order to compensate for 0 wear as it occurs both in the bumper and in the hinge itself. With these points in mind, it is the primary object of my invention to provide a combination hinge and bumper in which the bumper element is a part of the hinge and in which the bumper element is readily adjustable in order to take up for wear as it occurs.

Another object is to provide a hinge and bumper unit of this kind in a simple, practical and durable form.

The foregoing and other more specific objects of my invention will be made apparent in the course of the following detailed specification, reference being had to the accompanying drawing, wherein Figure 1 is a horizontal and fragmental section through a door and jamb showing my improved hinge and bumper unit in use thereon.

Figure 2 is an inside elevation of the inner face of the hinge leaf carrying the bumper element.

Figure 3 is an enlarged cross section through the bumper element alone.

Referring now with more particularity to the drawing, my improved hinge is designated generally at A and shown as in use in connecting the door B to the door support or jamb C. The hinge A comprises two similar hinge leaves or plates 5 and 6, each having one edge provided with spaced eyes "I arranged in interfitting relation and receiving the hinge pin 8 to pivotally connect the twoleaves. The leaf 5 is secured by screws 9 to the door B and the leaf 5 is similarly secured at H] to the jamb C. The eyes i are offset somewhat from the plane of the leaves 5 and 6 in such manner that, when the door Bis fully closed, there will be a narrow space between the two leaves.

The foregoing completes the hinge structure, per se, but in accordance with my invention one leaf, as 5, is provided near its free end with a longitudinally and medially extended groove or recess l which is cut deeper near the free end of the hinge leaf and gradually diminishes in depth toward the other end to thus provide a cam-acting face l2 angularly extended relative to the inner face of the hinge leaf. The deeper end l3 of this groove is spaced some distance from the free end it of the hinge leaf 5, thus leaving a shoulder I5,

1938, Serial No. 193,425

and through this shoulder is provided a bore l6 extended longitudinally along the center line of the hinge leaf and in a plane parallel with the groove face [2.

The bumper element D takes the form of a rubber or other resilient block of generally rectangular shape but having one edge I! faced or beveled off from end to end at an angle corresponding to the angle of the groove face l2. The block D is of such width as to nicely fit into the groove H and, the edge I! being placed against the cam-acting face 12, it will be readily evident that the opposite or working side N3 of the block will stand parallel with, but spaced outwardly from, the inner face of the hinge leaf 5. It will also be noted that by adjusting the position of the block D in the groove H, the projection of the block from the hinge leaf 5 may be readily varied.

For the purpose of adjusting the block D in the groove II, I provide the screw l9 which is journaled through the bore I6 and is locked against axial displacement by engagement of its head 20 with the outer end M and by a collar 2| which is secured on the screw and bears against the inner face of the shoulder E5. The threaded end of the screw i9 th n extends parallel with the groove face l2 and enters loosely a bore 22 which is cut through the bumper block D from end to end and parallel with the edge ll. A rod or pin 23 is extended transversely and rigidly through the block D at right angles to the bore 22 and traversing the same. This pin 23 has a diametrically extended and tapped recess 24 which receives the threaded end of the screw as shown.

In use the screw i9 is adjusted to draw the block D toward the deeper end of the groove l l in which position the block will contact the hinge leaf 5 as the door B is closed and will be compressed slightly to put a tension on the door such as will prevent rattling.

As wear occurs the screw 89 may then be adjusted to move the block D along the groove Ii towards its shallower end and thus increase the projection of the block from the hinge leaf 5.

It is understood that I may vary from the specific assembly herein shown and described, so long as such variations lie within the spirit and scope of the appended claims.

I claim:

1. A hinge comprising a pair of leaves pivotally connected at one margin, one of the leaves being formed with a transversely extended recess tapered inwardly from a relatively deeper to a relatively shallow portion so as to form a cam surface disposed angularly relatively to the inner 10 beyond the inner face of the leaf.

2. A hinge comprising a pair of leaves pivotally connected at one inturned margin to provide an intermediate space, one of the leaves being formed with an elongate, tapered recess transversely extended on its inner face, a resilient bumper element slidably confined within the said recess, and means for adjusting the location of the bumper element within the recess.

WILLIAM B. HUNT.
