RICHMOND E. NOLLEY, OF ATLANTA, GEORGIA.

HINGE.

SPECIFICATION forming part of Letters Patent No. 400,003, dated March 19, 1889. Application filed November 27, 1888- Serial No. 291,955. No model.)

To all whom it may concern.-

Be it known that I, RICHMOND E. NoLLEY, a citizen of the United States of America, and a resident of Atlanta, in the county of Fulton and State of Georgia, have invented a certain new and useful Blind-Hinge; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to the class of blind- I hinges that automatically hold the blinds open, the object being to cheapen and improve the construction of such hinges, and to cause them to operate more satisfactorily.

It consists of two leaves loosely pivoted together by a pin in oblong tapering recesses in the knuckles on the said leaves, details of all of which will be hereinafter fully described, and the parts claimed as new pointed out in the claim.

In the accompanying drawings, Figure 1 is a top edge view of the hinge, showing the two leaves. Fig. 2 is a side elevation of the hinge. Fig. 3 is a view of the pivoted end of the hinge. Figs. 4 and 5 are edge views of the two leaves of the hinge, showing the preferred form of the slots. Fig. (i is a cross-section on line aat, Fig. 2, showing the tapering form of the slot and the position of the pin when the blind is closed. Fig. 7 is a section. on the same line as Fig.6, being central to the pivoting-pin, but with the hinge in the position that it will assume when the blind is open. Fig. 8 shows an open blind, and by dotted lines the posit-ion the knuckle assumes when the blind is open, which has also been shown in detail in Fig. 7. Fig. 9 is a view of the hinge when the blind is closed, the parts having assumed the relative positions shown in Fig. (5 in detail.

The hinge shown in these drawings, and that will be hereinafter described, is known commonly as a "mort-ise-hingethat is, the leaves are let into the joint-faces of the windmv-frame and the blind-stile.

In these figures like reference-marks indicate corresponding parts in the several views.

A and B are the two parts of a hinge, the part A having the knuckle a and the part B having the knuckle b. The top part, A, and the bottom part, B, of the hinge are pivoted together by the pin 0, inserted in the oblong tapering recesses a and 1). One side of these tapering recesses a and b is parallel to the axis on which the hinge swings, and the opposite side slopes, as shown in Figs. 6 and 7 It will be observed by reference to Fig. 7 that when the hinge is in the position shown in that figure the pin 0 will lean over to the angle of the ends of the recesses oblique to the axis of revolution of the hinge and will hold the blind open, for the reason that the said pin being, when parallel to the axis of revolution of the hinge, the pivot on which the hinge revolves, it follows that when the pin is oblique to the axis of revolution of the hinge it cannot form the journal, and will act as a lock to prevent the revolution of the hinge.

In Figs. 4 and 5 is shown a notch in the side of the slot extending in the direction of and preferably, though not necessarily, decreasing in size toward and finally dying out at the bottom or smaller end of the tapering recess in the knuckle. This is to prevent any possible forcing of the pin into a vertical position by the wind or other force being applied to the blind without swinging the lower end of said blind in the direction that will force the pin to a vertical position. Ordinarily the friction of the sides of the slots on the pin and the weight of the blind will prevent the forcing of this pin into a, position parallel to the axis of revolution of the hinge; but if found to be necessary, as before stated, these said notches may be used.

It is obvious that this principle is capable of being used in other than mortise-hinges,- and that I do not confine myself to this specific construction of hinge.

, It will be seen that blinds supplied with this hinge do not require lifting to be released, merely requiring to be pressed overin the direction that will force the pin 0 into a vertical position to release the lock, which obviates all danger of the blind being lifted froin its place.

Havingthus described my invention, What I claim as new, and desire to secure by Letters Patent of the United States, is

In a blind-hinge, the combination, with the pin C, of the hinge-lea ves A B, provided, respectively, with knuckles (t I), having the oblong tapering recesses ct I), wherein said pin is seated, one side of said recess being parallel to the axis of thehinge and the opposite side oblique thereto, whereby when the blind is open the pin will lean over to the sides of the recess oblique to the axis of revolution of the hinge, as and for the purpose specified.

In testimony whereof I hereunto afiix my signature in presence of two Witnesses.
