BLIND-HINGE.

Specification of Letters, Patent.

. Patented April 20, 1908,

Application filed October 17, 1908. Serial No. 468,280. 7

To all whom it may concern:

Be it known that I, ANTHONY GEN, a citizen of the United States, residing at Bunkie,

in the arish of Avo elles and State of Louisiana, ave invente a new and useful Blind- Hinge, of which the following is a specification.

This invention relates to hinges and more particularly to, the kind used for supporting Ithas for its object to provide a hinge of that type designed to lock the blind to which it is ap lied in closed position.

Another object is to rovide a device simple in construction an comparatively inexpensive to manufacture embodying few parts and these so arranged as to reduce the tendency of derangement to a minimum.

With these and other objects in view as will more fully hereinafter appear the pres-v ent invention consists in certain nove details of construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and more particularly pointed out in the appended claims, it being understood that various changesin the form, proportion, size and minor details of the device may be made without de arting from the spirit or sacrificing any 0 the advantages of the invention.

In the accompanying drawingsiforming part of this specification, Fi ure 1 is a sectional plan view of a win ow frame and shutter showing the device a plied thereto. Fig. 2 is a perspective view of the hinge.

Similar numerals of reference are employed to designate corresponding parts throughout.

In carryin out the invention I connect the leaves with t e usual face of each leaf is isposed a lug. These lugs are constructed to engage each other when the inner faces of the leaves are brought adjacent each other.

The leaves 1 and 2 may be of any desired metal and are provided on their inner edges with the usual pintle knuckles 3, arranged to interlock in the usual manner, such as by roviding one leaf with a pair of spaced uckles disposed one adjacent either end of the leaf, and the other of said leaves with an intermediate knuckle adapted to fit between the spaced knuckles, the usual pintle 4 enters the openings of the knuckles and holds them connected in the usual manner. A portion of each leaf adjacent its inner or connected intle and onthe inner end is bent throu hout its entire length inwardly, and at rig t angles to the inner face of the leaf and 1gprallel to the pintle'3 forming an offset 5 portions are designed to be coincident with the outer faces of the window frame and blind when the leaves are secured in place as shown by Fig. 1. Thewidth of the main por tion of each leaf is substantially equal to the thickness of the blind and is provided with the usual screw holes 6.

ltiveted or otherwise secured to the inner face of each leaf is a locking lug preferably formed of a single piece of resilient metal of oblong shape and rectan ular in cross section, bent horizontally and at right angles to form arms 7 and 8 of equal length. The arm 8 of one lug is provided with an 0 ening to receive a rivet 9 by means of w ich it is secured to the intermediate portion and on the inner face of the leaf in such a position that the arm 7 will project inwardly with its outer face lying substantially in a plane with the outer edge of the leaf. The arm 8 of the o posite lug is similarly secured to the other leaf but a trifle farther outward so that the inner face of its inwardly rojectin arm 7 will lie substantially in a Iilanewit the outer edge of the leaf. 'Eachof the arms.

7 is corrugated in the d rection'of itsfwidth:

e outer faces of these offset and the lengthof each" arm is substantially 'i the same as the width ofthe oflset portions 5 adjacent theplintle, so that when theleaves are closed as s own by Fig. 1 they will be parallel and the inner face of the corrugated arm 7 of one lug will bear on the similarly formed arm of the other lug. It can be readily seen when the parts are in this posi-' tion the blind will be securely fastened and when it is desired to open the same a push outward on the blind will be suiiicient to overcome the tension of the arms 7.

What is claimed is 1. A blind hinge comprising a pair of leaves substantially right angular in cross section; each of said leaves being provided on its inner face with a locking member, said locking members being constructed to engage each other when the leaves are closed, whereby the blinds are held in closed position.

2. A blind hinge comprising a pair of leaves substantially right angular in cross section, each of said leavesbeing provided on its inner face with a resilient locking member, said locking members being constructed to engage each other when the leaves are closed, whereby the blinds are yieldingly held in closed position. v

3. A blind hin e com rising a pair of leaves, each of saicl leaves eing provided on its inner face witha resilient locking member sinuous in longitudinal section, said locking members positioned to engage each other when the leaves are closed, whereby the blinds are yieldingly held in closed position.

4. A. blind hin e comprlsin a pair of leaves substantia right angu ar in cross section, each of sai leavesbeing provided on' its innerface with a resilient locking member sinuous in longitudinal section, said locking 15 members positioned to engage each, other when the leaves are closed, whereby the blinds are held in closed position.

In testimony that I claim the foregoing as my own, I have-hereto aflixed my signature 2c in the presence of two Witnesses.
