HINGE.

sPEcIPICATION forming part of Letters Patent No. 365,552, dated June 28, 1887.

Application filed June 21, 1886. Serial No. 205,775. (No model.)

To all whom it may concern.-

Be it known that I, WARREN H. TAYLOR, of Stamford, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Butts or Hinges, of which the following is a specification, reference being had to the accompanying drawings, illustrating my improvements,

in which-- Figure 1 is a view of the hinge open. Fig. 2 is a view of the hinge closed, and partly in section through the knuckle.

It is well known that the advantage of a loose-joint butt is based upon the fact that it is more convenient for attachment to the door, and for hanging and unhanging the door, and that its cost is less than that of a fast-joint butt of the same size and quality. In durability, however, the fastjoint butt has heretofore proved superior, by reason of the greater num-- her of bearing-surfaces on which it carries the weight of the door.

Heretofore loose-joint butts have been constructed with asingle hearing at the point ofintersection of the knuckles of the two leaves. In some cases-such as iron buttsthe knuckles have borne against each other, while in but-ts of a better quality a washer of steel or other metal has been inserted between the knuckles of the leaves to form a hearing. In either I case, however, the entire weight of the door is borne by only one bearing, which, in case of severe strains, owing to heavy doors, causes the butts to crush and wear rapidly.

The object of my invention is, while retaining the advantages of a loosejoint butt, to increase its durability by providing an additional hearing at the end of the hinge-pin. I do this by inserting into the pin-hole of one leaf ablock or step of steel or other hard metal or substance, and so adjust the parts that one leaf of the hinge will bear upon both the upper end of the hinge-pin and upon the ably fixed thereto, so that it does not revolve when the upper knuckleis turned on the lower one; but this is not of the essence of the invention.

Referring to the letters upon the drawings, X X indicate leaves of the hinge. A indicates the hinge-pin rigidly inserted in the lower knuckle of leaf X and hearing at its upper end against the block or step B, inserted in the pin-hole or socket A of the upper knuckle of the leaf X.

G is a steel washer surrounding the pin A,

interposed between the abutting faces of the two knuckles D and D. This washer I consider desirable generally in connection with the bearing for the end of the hinge-pin above described; but, as before stated, it may or may not be used. It might be dispensed with, for example, in light hinges not liable to sustain much weight or strain. When it is used, however, it will be seen that the weight of the door attached to the leaf X is borne jointly by the block or step 13 and the washer O, instead of by the latter only, as in the usual construction. This will give two bearings instead of one, which will add to the ease of operation of the door and to the life of the hinge.

Obviously the pin might be inserted in the upper knuckle and the block or step in the lower without departing from my invention.

Having described my improvements, what I elaimis- 1. A loose-joint hinge constructed with two bearings, one formed by theblock l3 and hingepin and the other by the two knuckles of the hinge, substantially as set forth. 2. Ahinge consisting of the combination of a leaf, X, having a hinge-pin, A, a leaf, X, having a pin-hole or socket, A, a bearingblock or step, B, inserted in the pin-hole and forminga bearing for the end of the pin, and a washer, O, interposed between the leaves, substantially as set forth.

In testimony whereof I have hereunto subscribed my name.

VARREN H. TAYLOR.
