AWNING-BLIND HINGE.

SPECIFICATION forming part of Letters Patent N'O. 230,355, dated July 20, 1880. Application filed January 15, 1860.

To all whom it may concern:

Be it known that I, WALTER S. STOCKMAN, of Boston, in the county of Suffolk and State of Massachusetts, have invented .certain new and useful Improvements in Window-Shutters, (Case B and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form apart of this specification.

These improvements relate to that class of blinds which are used interchangeably as blinds or awnings; and they consist in the construction and arrangement of parts, as will be hereinafter more fully set forth.

In the annexed drawings, Figure l is an inside elevation. Fig. 2 is a side elevation of the device in use as an awning. Fig. 3 is a cross-section, showing a lower hinge. Fig. 4

is a side view of one of the upper hinges. Fig.

5 is an under view of the hinge, and Fig. 6 is a modification of one of the lower hinges.

In the drawings, A indicates the windowframe; B B, the window-blinds; O, the bolt; D D, the bolt-sockets; E, the leafof thelower hinge; F, the leafoof the upper hinge; a, the

hook-brace for holding the blinds in positionwhen used as an awning; b, the hooks for holding the brace when not in use; 0, the hook or loop on the window-frame for supporting the brace a when in use; d, the bracket for the lower hinge; c, the pintle of bracket; f, the ears on leafE, for engaging with the pintle c,- g, the pivoted locking-block; h, the spring; 1', the bracket for the upper hinge; j, the ear or socket of upper leaf, F, and k the limit-pin or stop.

The casing A and blinds B B are made in the usual manner and in any well-known form, and when made double, as shown, they are provided with the sockets D D and bolt G,

for locking them together when permanently closed and for use as an awning. The socket D is provided at its upper edge with a slit for the passage of the operating pin or knob of the bolt. I

The braces a are, by preference, attached to the blinds, as shown; but it is evident that they may be attached to the casing and be hooked into the blind and swung, as shown in Fig. 2.

The lower hinge is formed by the bracket d,-which is provided with pintle c, and is fastened to the casing, which forms one half thereof. The other half or leaf, E, is fastened to the blind, and is provided with one or more ears,f, which are left open, so as to pass onto or ofi from the pintle ewhen the blinds are swung out for use as an'awning. (See Fig. 3..) The leafE-is also provided witha block, g, having a concave face fitted to engage with the pintle 0. This block is pivoted, as shown, at Fig. 3, and is provided with a spring to throw it into the position there shown and to permit of its turning so as to unlock the hinge when the lower end of the blind is pushed out, and to form a lock or stop to preventthe blind from becoming detached when swung upon the hinges as a blind. As this block g turns with the hinge it is evident thatthe leafE can only be detached when the blind is swung from the top,'or upon the upper hinges, for a slight turn prevents the block g from having a sufficient movement to allow the pintle e to pass out from the earsf. I

The upper hinge is provided with a bracket, t, having a similar pintle to the bracket 61, and a hook-or catch, m.

The leaf F is attached to the blind, and is provided with a swivel socket or car, j, and a pin, it, the pin being shown atFig. 4, and, as shown, when the blind reaches the limit of its movement it engages with a notch in the pintle, which prevents the blind from being lifted by the wind when used as an awning.

It is evident'that this limit-pin may be attached to the pintle and engage with a limitnotch on the leaf F.

The swivel-socketj is provided with a projection, n, which passes under the hook m, and prevents the blind from being lifted when closed.

If it is desired to lock the blind from the inside the pin l (shown in Fig. 6) is us'ed,'and is made to passthrough the leafE into the earf, and when this form is used it is not necessary to use the block g-with it, as in that form the blind can only be detached from the lower hinge by design.

Having thus fully described my invention, block g, in combination with the bracket d, IO what I claim as new, and desire to secure by having pintle e, substantially as set forth. Letters Patent, is- In testimony that I claim the foregoing as 1. Theleaf F, having the swivel-socket j and my own I have hereto affixed my signature in 5 pin kyin combination with bracket i, having presence of two Witnesses.

a notched pintle for preventing the wind from WALTER S. STOGKMAN. lifting the blind and limiting the movement, Witnesses: substantially as and for the purpose set forth. ALICE G. STOQKMAN,
