HINGE-.L

SPECIFICATION forming part of Letters Patent No. 614,098, dated November 15', 1898-.

Application filed October 13, 1897. Serial No. 655,648- (No model.)

To (ZZZ whom it mag concern.- I

Be it known that I, MARTIN GALLAGHER, a citizen of the United States, residing in the city and county of Philadelphia, State ofPennsylvania, have invented a certain new and useful Improvement in Hinges, of which the following is a specification.

My invention relates more particularly to a hinge in which two plates are movably affixed to and revolve one upon the other when a door or shutter to which said hinge may be attached is opened or closed. i

It relates especially to and is an improvement upon the hinge invented by me and for which I filed an application in the United States Patent Office on April 23, 1897, Serial No. 633,440, allowed September 13, 1897.

The object of the present improvement is to render more efficient and easy the operation of said hinge bythe application of ballbearings thereto; and it consists of novel de-, tails of construction, all as will be hereinafter fully set forth, and particularly pointed out in the claim. 7

Figure 1 represents a plan view of a hinge embodying my improvement. Fig. 2 represents a side elevation thereof, showing it as applied in double arrangement to an extra heavy door. Fig. 3 represents a perspective view of the portion thereof that .is affixed to the door-frame, and Fig.4 represents a perspective view of that portion that is affixed to the door.

Similar letters of reference indicate corresponding parts in the several views.

My improved hinge consists of horizontallydisposed plates 0, (used in either single or double arrangement) rigidly secured to the vertically-disposed supporting-plate C or equivalent devices, said plate being secured to the door-frame A by any suitable means, that shown being the screws 0. In case the hinge is used in its single construction the horizontally-disposed plate 0 may be secured to the door-frame by a screw extension, prong, or such means, as well as by the plate 0 D designates a bracket or flap adapted to be secured to the sides of the door B, to which bracket are attached flat horizontallydisposed plates F, which are pivotally affixed to the horizontally-disposed plates 0 by means of the pivot-pin o and the openings f and c The vertically-disposed plate 0 is usually.

concave, and the door-frame made of similar form' to receive it, as shown, in order to allow,

of the free movement of the door-plates F when the door is opened or closed; 1

In using the hinge it is first attached to the door-frame. Mortises or slots which are the' width or depthof the combined thickness of the three or two plates used are formed in the edge of the door, extending parallel to the top and bottom and at right angles to the edges thereof, into which mortises the horizontallydisposed'plates are slipped and the same se-' cured to the door by means of the bracket D and its screws D. The hinge can also be se cured to the upper and lower edges of said door without in the least affecting its practicability. v

The above forms the subject-matter of my former application referred to.

My present improvement consists in forming channels, annular grooves, or ballways 0 upon the upper and lower faces of plates 0, as well as upon the inner faces of the plates F, as designated by F, to correspond with grooves c, and placing in said grooves balls or spheres F Figs. 1 and 2, upon which spheres plates F revolve or turn, it being obvious that all friction is thus reduced to a minimum and the swinging of the door or shutter or other article to which the hinge is, attached is rendered absolutely free and unhampered and the strength or exertion to be applied in opening or closing the door is of the smallest. The said spheres not only operate as perfect ball-bearings or antifriction means, but they also act as eflicient and perfect pivots, holding the fixed and movable parts of the hinge assembled and in juxtaposition, enabling the hinge to be used without the ordinary pivotpin as efficiently as with one and thereby performing a double function at one and the same time, which are the essential and novel results of my improvement.

In extra heavy doors the hinge may be used in double arrangement, as shown in Figs. 2, 3, and 4, and provided with and connected by suitable scrollwork, which imparts to the same the appearance of being one hinge.

Any suitable material can, of course,.be

used in the construction of my improved annular grooves or ballways in their upper and under surfaces, of a bracket adapted to be secured to the sides of a door, flat horizontally-disposed plates secured in the bracket, adapted to be seated in a mortise in the edge of the door, and spaced to embrace the horizontal plates, respectively, of the door-frame plate and having annular grooves or ballways contiguous to the grooves or hallways of the plate embraced thereby, and bearing-balls in said grooves or ways whereby the door member of the hinge is antifrictionally and pivotally connected to the door-frame member, substantially as described.
