JOHN WV. SKILTON, OF DAYTONA, FLORIDA.

HINGE.

SPECIFICATION forming part of Letters Patent No.7f3'7,784, dated April 19, 1904;.

Application filed August 11, 1903.-

embodying a pintle and socket carried opposite leaves of the hinge.

The invention has for an object to provide one member of the hinge with a socket adapted to contain a ball or roller bearing upon which the pintle from the opposite member will rest and to form this socket so as to provide achamber for containing lubricant, whereby a perfect ease of movement in the operation of the hinge is obtained, and the pintle being submerged in the lubricant is thoroughly lubricated and protected against rust where the hinge is used in an exposed position.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings, Figure 1 is an elevation of the hinge with the socket member in section. Fig. 2 is a vertical section on the line 2 2 of Fig. l, and Fig. 3 is a plan of the socket member of the hinge.

Like letters of reference refer to like parts in the several figures of the drawings.

The letter A designates a leaf or securingplate comprising one member of the hinge, and B a similar plate of the opposite member, which plates may be of any desired construction or configuration. The leaf A is provided with a socket A, which is closed at its lower end A and there provided with a curved bottom A upon which a bearing-ball A is disposed. This socket, closed at its lower end, forms an oil cup or chamber to receive the lubricant, and for facilitating the introduction and retaining sufficient oil to thoroughly Serial No. 169,123. (No model.)

fill the socket the upper portion thereof is recessed or enlarged, as shown at A The opposite member of the hinge is provided with a pintle B depending therefrom and adapted to enter the socket hereinbefore described, while the lower end of this pintle is curved or suitably shaped, as shown at B to secure the minimum of frictional contact with the ball or bearing surface at the lower end of the socket.

It will be seen that when the parts are assembled the pintle is provided with a ballbearing at its lower end, upon which the weight of the member carried by the leaf thereof is sustained while this contact and bearing is thoroughly lubricated by means of the oil-cup formed in the socket, thus securing a hinge embodying the greatest ease of movement, as the friction is reduced to the minimum while the bearing members of the hinge are protected by the oil-cup against rust or the entrance of grit by the body of oil which is retained at the upper recessed portion of the cup.

It will be obvious that changes may be made in the details of construction and configuration without departing from the spirit of theinvention as defined by the appended claims.

Having defined my invention and set forth its merits, what I claim, and desire to secure by Letters Patent, is

1. In a hinge, a leaf having at one side a socket member closed at its lower end and provided with an integral bearing-face, a single bearing-ball disposed at the base of said socket and resting upon said face, a pintle member carried by one edge of a cooperating leaf and located within said socket and provided with a contact-point at its lower end bearing upon said ball, and an upper portion for said socket spaced from the base of the pintle.

2. In a hinge, aleaf having at one edge a socket member closed at its lower end and provided with a concave face, a single bearingball disposed at the base of said socket, a
