Application filed October 3l, 1901. Serial No.l80,677. (No model.)

T0 a/ZZ whom, t 7gg/ay concern:

Be it known that I, WILLIAM L. EVANS, J r. a citizen of the United States, residing at Washington, in the county of Daviess and State of Indiana, have invented a new and useful Door-Hinge, of which the following is a specification.

The invention relates to improvements in door-hinges.

The object of the present invention is to improve the construction of door-hinges and to provide a simple and comparatively inexpensive one adapted to be readily applied to a door and a door-frame and capable of per` mitting a door to swing in' either direction and of automatically closing the door after it has been opened.

A further object of the invention is to provide a spring-hinge of this character in which the parts may be readily adjusted from the exterior to permit the spring to be tightened should it become loose through. long use.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l'is avertical seetional view of a door-hinge constructed in accordance with this invention and show-n ap plied to a door and a door-frame. Fig-2 is a horizontal sectional 'view of the same'.v Fig.

3 is a similar view illustrating the arranger ment ofthe parts `whe-tithe door is open."- Fig. 4 is a det-ail sectional view illustrating the manner of locking theyoke in an extended position to facilitate assembling the parts' when applying the hingeto a door anda door'- frame. Fig. 5 is a detailvvie'w'of the'leaf or plate which is secured to the"doorf'ran1e.'

Fig. 6 is a similar viewof the-leaf or-'plate"v which is secured to the door.I

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a plate or leaf designed to be secured to va door-frame with its outer face iiush with the adjacent face ofthe saine and provided with lateral wings or extensions 3 to form bearing-faces for rollers 4 of a leaf or plate 5, which is secured to .a door 6. The

tion.

plate l isprovided with a central inwardlyextending approximately semicircular transverse portion 7, and it has apertures 8, located above and below the transversely-disposed portion 7. The inwardly-disposed transverse portion 7 forms an exterior recess for .the reception of a lug or eye 9 of the leaf orplate 5 of the door. The plate 1 is secured to the door-frame 2 by screws or other suitable vfastening devices, and it-has fastened to its u'pper and lower portions 'an inwardlyextending approximately U shaped supportingframe 10, provided at 'its 4front end with iianges or arms 10a, which are perforated for the reception of screws l1 or other suitable fastening devices for securing the supportingframe to the plate 1. f v

The approximately U-shaped 'supportingplate,which has upper and lowerlsid'es, is provided at its inner or rear end with a bearinglopening 12 for the receptionlofYY-the inner or I rear end 13 of a guide-bar 14,which is provided at its outer or front end 15 with a'reduced por- The outer or front end A15 is arranged in a bearing-opening 16 of theinwardly-extending transverse poi-ti'on'7 ofthe plate l and is provided with a groove 17 for thevreception of the blade of a screw-driver for enabling the 'guide-bar 14 to be rotated. The reduced ends ofthe guide-bar, which is round, form jour# The nut 18 isarranged on a'threaded portion 2O of the guide-bar and receivesthe outer or front end of the coiled spri-ng 19,which has its other end engaging a yoke 2l. The yoke 21, which is approximately U-shaped, conforms to the general configuration of the U-shaped supporting-frame, which has' upper and lower sides extending throughthe apertures 8 of the plate 1 and connected byfa verticalpin or pintle 22 to the lug 9 of 'the' leaf 4or plate '5. The pin or pintle is provided at its upper end with a groove for the reception of a screw-driver, and its lower end is threaded 'andenga'ges a 'threaded opening of th e lower side ofthe yoke,

Inals to permit the 'said'guide-bar to be rotated y ,for moving a nut 18 inward and outward to lvary the tension of a coiled spring 19.

IOO

plate 5 is provided at opposite sides with lateral extensions having upper and lower eyes or bearings 23 for the reception of vertical pins or spindles 24, upon which the vertical rollers 4 are mounted. The rollers 4, which extend laterally beyond the door G, as clearly shown in Figs. 2 and 3 of the drawings, are adapted when the door is opened in either direction to form a movable fulerum and to roll on the lateral extensions or wings 3 of the plate 1,\vhereby the coiled spring will'be compressed by the yoke,which is drawn outward by this lnovement of the door. The opening of the door carries the lug or eye 9 outward from the recess or cavity of the center of the plate l to the position shown in Fig. 3, and when the door is released the spring will expand and return the door to its closed position. The pins or spindles are designed to be removable to enable the rollers to be detached, and when the rollers are removed the frictional engagement of the eyes and the plate l will be su'lcient to hold the door in its open position, and, ifdesired, the hinge may be constructed without rollers.

Vhen it is desired to apply the hinge to a door, the yoke is drawn outward to the position illustrated in Fig. 4 of the drawings and is held there by means of a removable pin or plug 25. The pin or plug 22 may then be removed to separate the leaf or plate 5 from the yoke. The plate l and the parts carried thereby are mortised in the door-frame, and the other plate 5 is similarly mounted on the door, afterwhichitiseonneeted withtheyoke. The pin or plug 25 may be readily removed by drawing the yoke outward slightly to free the plug or pin from the plate l, and the hinge is then ready for use.

After the door has been hung the spring can be given the desired tension by opening the door the full width and inserting a screwdriver in the groove of the outer end of the rotary guide-bar, and should the spring become loose or weakened at any point it may be readily tightened in this manner. Should occasion require, the door may be removed by arranging the parts as shown in Fig. 4 and detaching the plate 5, and the groove in the outer end of the rotary guide-bar will then be readily accessible.

In order to facilitate the adjustment of the rotary guide-bar, the lug or eye 9 of the leafplate 5 is provided with a notch or recess 9, adapted to receive the stem or shank of a screw-driver to permit the blade of the same to be readily engaged with the groove of the rotary guide-bar.

It will be seen that the hinge is exceedingly simple and inexpensive in construction, that it possesses great strength and durability, and that it will permit a door to swing in either direction and will automatically close the door. It will also be apparent that the slidable member or yoke receives the nut and prevents the same from rotating on the screw portion of the guide-bar when the latter is rotated for adjusting the spring.
