HINGE FOR AWNING-BLINDS.

SPECIFICATION forming part of Letters Patent No. 310,076, dated December 30, 1884:.

Application filed October 8, 1883.- (N0 model.)

To ctZZ whom it may concern:

Be it known that I, PATRICK K. OLALLY, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Blind or Shutter Fixtures, of which the following is a specification.

This invention has for its object to provide improved devices for hanging outside windowblinds, so that they can swing on vertical pivots, like the ordinary blinds, or be disconnected from their lower pivots and inclined outwardly from the building, so as to serve as awnings; and to this end the invention consists in the improvements hereinafter described and claimed.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a perspective view of a window-casing viewed from the inside, showing a half-opened blind provided with my improvements, the blind being connected to the casing by both of its hinges. Fig. 2 represents a perspective view, showing the blinds swung outwardly at the bottom, the members of their lower hinges'being disconnected. Fig. 3 represents an edge view of a blind connected to the casing by both of its hinges. Fig. 4; represents an edge view of a blind swung outwardly at the bottom, as in Fig. 2. Fig. 5 represents a perspective view of the lever which constitutes a member of the lower hinge, and a brace to hold the blind in the position shown in Figs. 2 and 4. Fig. 6 represents a perspective view of a part of a hinge.

The same letters of reference indicate the same parts in all the figures.

In the drawings, a a represent outside blinds or shutters of ordinary construction,and 1) represents a window-casing to which said blinds are connected.

0 d represent the hinges which connect the blind to the casing. Each hinge has a fixed member or pintle, 2,which is rigidly attached to the casing, and a socketed or swinging member which receives said pintle and swings with the blind. The socketed member of the lower hinge, c, is a bent lever, e, pivoted to the inner surface of the blind by means of a socketed plate, f, secured thereto, and having at one side of said plate a shorter arm, 3, containing the socket 4, which receives the pintle, and at the other side of said plate a longer arm, 5, which stands at about a right angle with the arm 8. The socketed member of the upper hinge, d, is a plate, h, having the pintlesocket at one end, and pivoted ati to the edge 5 5 of the blind, (instead of being rigidly secured t11ereto,) so that the blind can swing outwardly from the casing at its lower end on said pivot 4. without disturbing the connection of the members of the upper hinge, as shown in Figs.

2 and 4.. The plate h of the upper hinge may be of the common construction, (shown in Fig. 6,) only one screw being employed to secure it to the blind, the other screw-holes being left vacant. \Vhen the members of the lower hinge are connected, as shown in Figs. 1 and 3, the shorter arm 3 of the lever e is in a horizontal position, and the longer arm 5 in avertical position, and rests against or is in close proximity to the inner side of the blind,where it is held by a suitable catch, 8, secured to the blind, the arm 5 being sprung into place behind said catch. The blind can now be turned on both hinges in the usual manner. When it is desired to convert the blinds into an awning,they -7 5 are secured together by a locking device, and the movable members of the lower hinges are disconnected from the fixed members by turning the levers c on their pivots so as to raise the arms 3 from the pintles, as shown in dot- 8o ted lines in Fig. 3. The lower ends of the blinds are now free to swing outwardly on the pivots i,which connect the upper hinges with the blinds. When the blinds are swung outwardly as far as desired, the longer arms 5 are secured to studs or other suitable fastening devices on the casing, and act as braces to hold the blinds in their inclined position, as shown in Figs. 2 and 4. The membersof the lower hinges may be again connected by restoring lever e is arranged at such height relatively to 9 5 the pintle or fixed'member of the lower hinge that when the longer arm 5 is engaged and held by the catch 8 the shorter arm 3 will be moved downwardly onto said pintle to sucha degree that it will wholly sustain the weight of the blind, so that no considerable strain will be exerted on the pivoted member h of the upper hinge. This function of the lever eviz., supporting the weight of the blindis an important one, because the pivotal connection of the upper hinge to the blind makes said hinge incapable of supporting the weight of the blind to any considerable extent. In case, however, an upper hinge were employed which is capable of supporting the weight of the blind,this function need not be exercised. The sockets 4 in the arms3 are enlarged or countersunk on' the under sides of said arms, as shown in Fig.5,to facilitate the entrance of the pintles into the sockets. The pintles of the hinges are preferably curved to conform to the arc of a circle in which the sockets 4 move in slipping on and off the pintles. Said curvature is not essential, however, as the sockets 4 may be made sufficiently large to'readily engage with straight pintles. The part of the lever e that is pivoted to theblind may be sunk into a recess in the face of the blind, instead of being contained in asockct in the platef,in which case said plate would be fiat; or a screw eye or eyes may be substituted for the socketed plate. The outer end of the arm 5 may be formed with an eye to engage a stud 011 the casing, as shown, or may be formed with a hook to enter an eye on the casing.

Theblinds, when adapted for use as awnings, may be held at different inclinations by means of studs or securing devices placed at different points on the casing; or the arm 5 may have a series of slots adapted to receive the head of a screw eye or button on the casing, said screwcye being turned half around after its insertion into one of said slots, and thus caused to hold the arm 5.

hen the blinds are to be used as an 'awning, they should be securely locked together.

I am aware that hinges for awning-blinds have been made by which the blind might be swung on said hinges, as is usual, or swung out at the bottom in form of an awning. I donot broadly claim such invention.

1. The combination,with a window blind or shutter, of an upper hinge composed of two members, one member being fixed to the casing, and the other member pivoted to said blind, substantially as described.

2. The combination, with ablind or shutter, of an upper hinge composed of a member fixed to the casing and a member pivoted to the blind, and a lower hinge consisting of a fixed member attached to the casing and a socketed arm pivoted to the blind, the longer lever of said socketed arm having a loop or device to retain the blind in its inclined or awning po sition, substantially as described.

3. The combinatiomwith a blind or shutter, of an upper hinge constructed substantially as described, and a lower hinge consisting of a member fixed to the casing and having a curved pintle, 2, and a socketed arm pivoted to the blind in such position that its socket will turn in a curve corresponding with that of the pintle, and aproplever, 5, attached to said socketed arm, substantially as described.

4. The comhinatiomwith a blind or shutter, of an upper hinge consisting of two members, one member hinged to the blind and the other fixed to the casing, and a lower hinge consist ing of a fixed member on the casing having a curved pintle, and a socketed arm pivoted to the blind, the arm provided with a loop to pass over said pintle, the other arm of said lever serving as a support to'the blind when swung outward into position as an awning, all the parts being constructed and relatively arranged, substantially as described.

In testimony whereof I have signed my name to this specification ,in the p resenceof two subscribing witnesses, this 6th day of October, 1888.

PATRICK K. OLALLY.
