HlNGE' FOR AWNING-BLINDS.

SPECIFICATION forming part of Letters Patent No. 231,655, dated August 31, 1880. Application filed April 23, 1880. (Model) 10 all whom it may concern:

Be itknown that I, CHARLES P. DEARBORN, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Blind-Hangings, (Case 13,) of which the fol lowing description, in connection with the accompanying drawings, is a specification.

This inventioi'l relates to improvements in blind hangings or hinges of that class which permit the blinds to swing separately about a vertical pivot, or both turn out at bottom on horizontal pivots at the tops of the blinds to permit the blinds to serve as an awning.

In a patent of the United States heretofore granted to me, No. 202,935, I have shown and described a lower hinge the socket portion of which is made vertically movable, so as to remove the said socketed part from the hingepintle when it was desired to turn outward the bottom of the blind to enable the blind to serve as an awning, the entire weight of the blind during such operation resting upon the upper hinge.

My present invention is an improvement on the hinge described in the said patent, and relates, chiefly, to providing a hinge of this class with lockin g devices to prevent it from being lifted or disengaged from the pintle by a person outside the house. I have also shown the said socket portion pivoted on a stud, so as to move in the arc of a circle, which makes a stronger, more easily operated hinge, and one of less cost.

the other figures; and Fig. 8, a detail of part of the lower hinge, to show more clearly the provision herein made to lock the blinds open when the blinds swing, as usual, on the vertical pintles.

In the drawings, (it represents the casing or fixed part of the building, and b the side rail of a blind.

The upper hinge, c (1 cf, is as in my patent referred to, c carrying the upper pintle, d being attached to the blind, the socket 6 being connected loosely with part (I by a pivot,f, as in Fig. 3. The meinberg ofthe lower hinge, to be attached to the casing or building, has a pintle, h, and a lateral projection, with a fastening-stud, i, or notch, and a stop,j, to prevent the blind being accidentally lifted from the upper hinge. That member of the lower hinge to be connected or move with the blind is composed of a plate, 70, having holes 2 to receive screws, by which to attach it to the blind, and of a movable socket part, 1,

preferably pivoted to the part It; by a pivot, 3, so that the said socketed portion may be turned in the arc of a circle when being lifted from the pintle. This socketed part has one part of it (marked m) prolonged to form one portion of the socket-part locking device, the other co-operat-ing part being arnovable stop, a.

In Figs. 1 to 6 thcpart m is made as a hook, and the part it as a segmental plate pivoted at '4, and having a pin, 5, by which to turn the plate. When the platen is as in dotted lines, Fig. 1, the socketed part cannot be lifted or moved from its engagement with the pintle from the outside of the blind; but when as in full lines, Fig. l, the socketed part may be turned on the pivot 3 and lifted or removed from the top of the pintle, to permit the lower endof the blind to be turned outward, as in Fig. 3.

The socket part I has a handprojection, 0, to be grasped by the person opening the blind, if it is desired to detach the socket portion from the pintle. Extendingfrom thelowerend of the socket portion is a short arm, 1), which, when the blind is opened, falls behind the projection 2', before referred to, of the fixed member g, or into a notch in the said member,'to

hold the blind open when swung outward on the vertical pintles. When the blinds are to be closed from the inside the plate a or n is disengaged from the socketed part Z, permitting the latter to be lifted just far enough to elevate the projection 12 above the projection 2'. This obviates lifting the blind when it is to be unfastened an d closed, which is customarily done in blinds now commonly in use of the Charles Parker class, such lifting of the blind to enable it to be closed resulting very frequently in lifting it a little too far when the blind is thrown from the building.

The device for holding the two blinds together when being used as an awning may be of any usual construction.

In Fig. 7 I have shown a modification illustrating the application of a locking device for the socketed part when the same is slotted, as at 6, to slide vertically on pins 7, as illustrated in my patent referred to. In the said figure the movable member of the locking device (therein distinguished by the letter W) has a slot to permit it to be guided by and turn on apin, 8, when,as in full lines, the part a meets the upper part of the movable soeketed member and looks it, so that it cannot be lifted; but when in the position shown in dotted lines the socketed part may be freely lifted from the pintle.

I claim 1. The pintle member g, provided with the projection '13, combined with the socket portion 1, made detachable from the pintle while the weight of the blind is supported by the upper hinge, and provided with a projection), to cooperate with the projection of the fixed member g, to hold the blind securely when opened, substantially as described.

2. In a hinge for awnin g-blind s, the plate It and the socket portion Z, pivoted thereon, as described, and provided with the hand-projection located at the inner face of the blind, to permit it to be turned about the pivot 3 and disengage the socket from the pintle, whilet-he upper hinge supports the weight of the blind, in combination with the blocking device, to cooperate therewith and prevent the socket part from being lifted from the pintle, as set forth.

3. In a hinge for awning-blinds, the plate It and socket portion Z, pivoted thereon, provided Willi the hand-projection 0, located at the inner face of the blind, substantially as described.

4. In a hinge for awning-blinds, the plate k and socket part I. pivoted thereon, provided with a handle portion, 0, and hooked projection 112, combined with the movable plate, to engage and hold the said hooked portion m, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES P. DEARBORN.
