DETACHABLE SCREEN-DOOR HINGE.

Specification of Letters Patent.

Application filed December 18, 1907.

Patented June 9, 1908.

Serial No. 407,055.

To all whom it may concern:

Be it known that I, JAsoN O. TAYLOR, a citizen of the United States, residing at WVilloughby, in the county of Lake and State of Ohio, have invented a new and useful Detachable Screen-Door Hinge, of which the following is a specification.

The invention relates to improvements in detachable hinges. The object of the present invention is to improve the construction of detachable hinges, and to provide a simple, inexpensive and efficient hinge, designed particularly for use on screen doors, and adapted to enable the same to be easily put on and taken off.

Another object of the invention is to provide a hinge of this character, adapted to be applied to a door frame or casing Without recessin the same.

Wit these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to with out departing from the s irit or sacrificing any of the advantages of t e invention.

In the drawing :Figure 1 is a front elevation of a detachable screen door hinge, constructed in accordance with this invention. Fig. 2 is a rear elevation of the same. Fig. 3 is a vertical sectional view, taken substantially on the line 3-3 of Fig. 1. Fig. 4 is a detail perspective view of the detachable leaf. Fig. 5 is a similar view of the permanently attached plate. Fig. 6 is a detail per- 5 ective view of the pin or stud. Fig. 7 is a etail view of the rotary locking member.

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

The detachable spring hinge comprises leaves 1 and 2, pivotally connected and engaged by arms 3 and 4 of a spring 5, which operates in the usual manner. The leaf 1 is designed to be secured to a screen door by screws 6, or other suitable fastening devices, and the other leaf 2 is detachably secured by the means hereinafter described to a permanently attached securing plate 7, secured by screws 8, or other suitable fastening devices to the door frame or casing, or other suitable support. The leaves 1 and 2 are formed with flanges 1 and 2*, located at the inner edges of the leaves and. arranged at an angle to the plane of the outer faces of the same and projecting outwardly when the hinge leaves are assembled. The flange 2 is shorter than the flange 1 This being the case it follows that the inner face of the leaf 2 is off-set outwardly or forwardly from the plane of the inner or rear face of the leaf 1 to provide a space for the permanently attached plate and to avoid recessing the door frame or casing to accomplish this result. The permanently attached late 7 is provided at its inner face, which is 'tted a ainst the door frame or casing, with a plurality of shallow corrugations 7, which may be arranged in any preferred manner. These corrugations reduce the weight of the plate and lessen the amount of metal in the same without impairing the strength of the plate.

The permanently attached plate is provided with a key hole slot 9, consisting of an enlar ed circular portion and a vertical rectangu ar extension. The key hole slot permits the outer portion of a pin or stud 10 to pass through the permanently attached late before the same is applied to the door frame or casing. The in or stud 10, which is arranged horizontal projects from the outer face of the permanently attached plate, and is provided at its inner end with a rectangular head 11, which fits in a recess 12 in the rear or inner face of the permanently attached plate. This interlocks the stud with the permanently attached plate when the parts are assembled, and the pin or stud is thereby held against rotary movement. The pin or stud is provided at its outer end with aradially arranged lug 13 of a size to ass through the rectangular portion of the key hole slot, and adapted to be engaged by a locking member 14, which engages the leaf 2 and detachably secures the same to the permanently attached plate.

The leaf 2 is provided with a double key hole slot 15, consisting of a circular opening and upper and lower vertically arranged rectangu ar extensions, and adapted to permit the spring hinge to be reversed to permit a door to be hung at either the right or left hand side. The locking member 14 is provided with a key hole slot 16, consisting of a circular opening of a size to correspond with the pin or stud and a recess of a size to permit the member 14 to be passed over the outer end of the pin or stud 10.

The pin or stud 10, which is circular in cross. section, forms a support for the leaf 2 and a combined' pivot and su port for the locking member after the loc ing member is placed on the pin or stud, it is adapted to be partially rotated to carry the recess away from the stud. The locking member is provided with an inclined or angularly disposed cam face 17 for engaging the stud, whereby when the locking member is rotated to carry the recess away from the lug, the said locking member will be tightly wedged between the stud and the leaf 2. The locking member 14 is provided with an arm 18to enable it to be readily rotated by hand, and it has a polygonal wrench-receiving portion 19 to enable it to be operated by a wrench, or other suit able tool. The cam face 17 is located at the wrench-receivin portion, as clearly shown in Fig. 7 of the drawing. The locking member is readily operated to lock or release the hinge.

The permanently attached plate is provided with a central raised portion or boss 20, and it has upper and lower lugs or bosses 21 for interlocking the leaf 2 with the permanently attached plate. The leaf 2 is provided with a central recess 22 to fit the boss 20, and it has upper and lower recesses 23 to receive the lugs or bosses 21. This construction interlocks the leaf 2 with the permanently attached plate, when the parts are assembled, and the pin or stud is thereby relieved of the strain incident to the weight of the door.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is
