TO ALL WHOM IT MAY CONCERN: p

Be it known that I, JOHN E. DOWNS, of Lowell, in the county of Middlesex, and State of Massachusetts, have invented new and useful Improvements in Combination Hinge and Fastener for Blinds, and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in so forming and combining a hinge and fastener that it will give the required strength and support to a blind, and also to secure the same in its desired location.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construetion and operation.

Figure 1 represents a front elevation of a window-easement, with blinds hung and provided withmy improved combination hinge and fastener.

Figure 2 represents a plan of the insiderof easement, showing the fastener.

Figures 3 and 4 are details of the combination hinge and fastener.

Similar letters in the different gures indicate corresponding parts.

a represents the easement, b the sill of the window. Near the top and bottom, and on each side of the easement a, and secured to the same, is the "male portion of the hinge @which is supplied with the required vpintle and a suitable flange, with counter-sunk holes, for the reception of the requisite screws to' fasten the same as required. l

I construct the female part of the hinges, both for the top and bottom of the blind, with suitable sockets, d, to receive the pintles; the length of the leaves e andfcorresponding with the width ofthe blinds, the leaves of the top hinges, e e, projecting downward on both Stiles, g and L, so as to receive one or more screws; the leaves of the bottom hinges, ff, projecting upward on both stiles, g and 7i, sufficiently to receive the required number of screws; the length of these leaves, e e and ff, being determined by the width and weight of the blind, projecting across the entire width of the blind, or less, as may he desired.

To the bottom leaves of the hinges ff, the projections z'z' are cast on' or secured to the same, as represented in fig. d of the drawings, by dotted lines, they being furnished with the bushings jj, their length being the thickness of the bottom part of the blind, on the end of which the fastener, t, is secured, by means of a screw. This fastener k is provided with the slats ZZ, through which the screw m passes, forming a guide for the same.

The window sill b is provided with suitable catches, n n, driven into the same vertically, inclining outward. Similar catches are used and driven intothe wall of the house, horizontally with these catches n n. The heels o o, of the fasteners c k, fasten the blind on the inside when closed, and to the walls of the bouse when open, being of themselves self-opernting- I Ordinarily, in common blinds, their construction'is such, the tenons of the slats being so short and shallow, that it affords but very little strength to the blind, and is scarcely, if any, prevention to the sag of the same. And further, the usual short leaves of the hinges are entirely inadequate to support the Weight of the blind, they also being exposed to extreme wet, dry weather, and winds. These several causes tend and result in the sag ofthe blind, causing the slats to become loose, preventing the blinds from being closed, or fastened back when open, making thcmnnservicenble and unfit for use, and oftentimes entirely destroying them.

These common and serious difficulties are entirely obviated in the constructionv and arrangement of my improved combination hinge and fastener.

The female part e e andff, being applicable to the male part of old hinges now used, and can be easily attached te the saine. s n

The leaves e e andff, of the female part of the hinges, are supplied with a suitable rib, to give them the required strength, their length being the width of the blind, if desired, and of suitable width to receive a Sudioicnt number of screws, which fasten it firmly to the bottom, top, and stiles g and h of the blind.

This construction and application of theleaves'e e andff to the blinds, give increased firmness, strength,

t neither wind nor weather affects them, and consequently support, and durability to the same, so much so tha ombination with the fastener,

they are always in perfect working order; and also, this arrangement being in c they are always reliable to shut and fasten, and fasten when open.

What claim as my invention, and desire to secure by Letters Patent, is The combination and arrangement of the. hinge ef, and fastener c, when arranged for the purposes as described and fully set forth.
