sncrecarron forming part of Letters Patent No. 398,752, dai-ed :February Application tiled May 14, 1888. Serial No. 273,822. (No modela To all wh/0711. it muy con/cern:

Be it known that l, CHARLES J. SEYMOUR, oi' Brookline, in the county olf Nort'olk and Siate olf Massachusetts,have invented certain new and useful lmprovemeni s in lioclellinges, ol' which the following is a specieation. Y

This invention has for its objectio provide i'or use on buildings a combined hinge and locking device for outside window blinds or shutters, whereby the blind may be securely `held when fully open ed, fully closed, or at intermediate positions.

The invention consists in a hinge com posed ol,tirst, a fixed member having a horizontal web or plate provided with a central socket. to receive the pintle oi' the swingin member, a series ot sockets concentric with the central socketto engage a vertieally-movable latchbolt on the swinging member, and vertical flanges o r ears adapted to bear on the window-Casin an d provided with holes for attachi n g screws; secondly, a swin `grin g member composed olf a shank or arm adapted to be attached to the blind and havinga pintle formed to enter the central socket of the fixed member and a rib or shelf containing an orifice, and, thirdly, a latch pivoted at one end to the arm ot' the swinging member and having at its swinging end abolt` or stud adapted to pass through the orifice of the rib or shelf of the swinging member and engage either of the outer sockets of the fixed member, and thereby lock the hinge in an;7 desired position, said latch havingl a handle projecting through the blind, whereby it ma)r be operated when the blind is closed.

Ot' the aeeompanying drawings, Vorming a part oi' this speeiieation, Figure l represents a perspective. view ot the hinge with its parts discomxected. Fig. 2 represents a front view of the hinge applied to a blind, the latter being closed.

The saine letters oi.' reference indicate the same parts in both iignrcs.

ln the drawings, a represents the. blind, the upper hinge (not shown) olf which may be oi' any suitable construction. l) rejnesenis the movable member, and c the fixed member, of the lower h in The movable member is composed ot a shank or arm adapted to be attached to the side ot the blind. and bent ontwardly near one end,and there provided with 26, ieee.

a downwardlv-projeetingI pinile, 2, which is,

b v the bent form ot the sl1ank,ot`fsetfrom the side oi' the blind. The shank has a horizontal ledge or rib, 2l, in which is formed an oriiee, l. Said rib l'orms a rest or lsuppfnt for the swinging end of a lateh, d, the other end ot' wliiehis pivoted at e to the inner end ol the member I1. Said latch has a downwardlyprojeeling bolt or sind, 5, which formed to enter the orifice i in the rib 3 and to project below the latter when the latch is depressed.

The xed member of the hingeis composed of a horizontal plate or web, G, and vertical `ears or flanges l() '1,0 formed thereon, said ears being 'formed to bear on the front and side olf a window-easing and provided with holes to receive the screws that secure. the fixed 1nem ber to the easing. The plate or web C is provided with a central socket, l2, which receives the pinlle 2, and with sockets 7 S 9 9, arranged in a curved series concentric with the pintle socket l2. Said sockets 7 S J .fl are adapted to coincide with the oriiiee i in the rib ot' the swinging member, and are formed to receive the stud or bolt 5 of the latch. lVhen said stud passes through the orifice l in the rib and is inserted in one of the sockets '7 S 9, it locks the two hinge members together, as will be readily seen. The arran gement of the sockets 7 S 9 is such that when thelatch-bolt is in the socket T the blind is locked in its closed position, and when the bolt is Vin the socket S the blind is loeked in its opened position; but. when the bolt Ais in one of the sockets 9 the blind is locktal in an intermediate position.

The latch isprovid ed with aliandle, 13, near its swinging end, which projects backwardljv through an, opening, lo, formed for it in the swinging member olf the hinge and in the blind, said handle extending through the blind, so that when the blind is closed a person at the inside can operate the lateh. A loop or guide, y, is attached 1.o the side ot' the blind to limit the upward movement of the latch and prevent its bolt i'rom being withdrawn from the orifice in the. rib 25.

l am aware that the swinging member of a hinge has been provided with a pivoted latch which is adapted to engage notches in the fixed member of the hinge to lock the hinge in different positions; hence I do not claim, broadly, a hinge having a pivoted latch on its IOO swinging member and notches in its fixed member to engage said latch.

My improved hinge differs from any of which I am aware in the following particulars, viz: First, the fixed member is a horizontal plate or web having vertical flanges, whereby it may be attached, and a series of latch-engaging sockets concentrically arranged with relation to the hinge-pintle socket; second, the swinging member is bent or oi'lset at its pintle-carrying end, and is there prQvided with the rib 3,-which strengthens the swinging member, and, by its engagement with the latch bolt or stud at the same time that said bolt is engaged with one of the sockets of the iixed member, holds the latch in place laterally and relieves the latch from all lateral strain.

To insure close contact of the rib 3 with the web or plate (3 around the latch-receiving sockn ets, I provide the under side of the rib with a boss, li, through which the orifice 4c extends. The orifices i 7 S 9 S) are preferably beveled, the orifice i being largest at its lower end, while the orifices 7 8 t) 9 are largest at their upper ends. This enables the rib 3 and. web

or plate 6 to bear on the latch-bolt 5 at points close to each other, so that there will be no tipping strain on the bolt.

That I claim isf In a locking-hinge, the combination f the fixed member composed of the horizontal plate or web having the central pintle-receiving socket, l2, the concentrically-arranged latchreceiving sockets 7 8 9, and the vertical ears or flanges l0 10, the swinging member composed of a shank or arm secured to the outside of a blind and having a pintle, 2, atene end and bent or offset near said pintle, and

provided with the rib 3, having an orifice, 4, and the latch d, pivoted at one end to one end of the swinging member, and having at its swinging end the downwardly-proj eetin g stud or bolt 5, adapted to pass through the oricc of the rib 3 and enter one of the sockets of the fixed member, and also provided near its swinging end with the handle 13, adapted to project through the blind, all arranged and operating substantiallT as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 10th day of May, 1888.
