A. FERBER, OF ELIZABETH, NEW JERSEY.

OPERATING WIN D OW-BLIN DS.

Specification of Letters Patent No. 20,996, dated July 27, 1858.

To all whom t may concern.'

Be it known that I, A. FERRER, of Elizabeth city, in the county of Union and State of New Jersey, have invented a new and useful Improvement in VVindow-Blinds; and I do hereby declare that full, clear, and exact description of the same, reference being had to the annexed 'drawings, making a part of this specification, 1n which` ligure 1, is a face view of a window blind constructed according to my improvement. Fig. 2, is a section of ditto, taken in the line a', Fig. 1. Fig. 3, is also a section of ditto, taken in the line y, y, Fig. 1.

Similar letters of reference indicate corresponding parts in the several iigures.

This invention consists in having the rod to which the slats are attached, tted in one blind, and having the slats attached to the rod, and the rod secured to the slide as hereinafter shown, whereby the rods cannot obstruct the light nor serve as encumbrances as hitherto, nor the slats be allowed to turn or move casually. The invention improving the appearance of the blind and also rendered it more durable than those of usual construction.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents the frame of a blind, which is of rectangular form, a, a, are the stiles, and .71, the top and bottom traverse pieces.

B, represents the4 slats, the ends of which have tenons c, formed, on them as usual, said tenons being fitted in holes in the stiles as in the ordinary way. To one end of each slat B, a. metal plate al, is attached. These plates project at right angles from the inner sides of the slats, and each plate has a slot e, made in it, said slots having oblique positions relatively with the ends of the slats as clearly shown in Fig. 2.

C, is a rod which is fitted in a rabbet f, in one of the stiles a, and adjoining the ends of the slats to which the plates CZ, are attached, the rod C, is of square form and its outer side is .iiush with the stile in which it is fitted. The rod C, is secured in its rabbet by screws g, which pass through oblong slots 71 in the rod C, see Fig. l. To the side of the rod C, pins z', are attached, said pins projecting from the rod at right angles and fitting in the slots e, of the plates (Z. v

In the rod C, a mortise y', is made and a the following is a l spring lc, is placed in said mortise, said spring being attached to the stile as shown at Z. This spring is constructed of wire of suitable thickness with a coil m, formed in it and its outer end is bent inward so as to form a shoulder or catch as shown at n. Directly over the mortise j, a plate D, is secured and a slot o, is made in said plate.

From the above description it will be seen that by moving the rod D, up and down, the slats B, will be opened and closed, when the slats are closed the shoulder n, of spring 7c, will project through the slot o, of plate D, and form a fastening and when the slats are turned open or partially open, the shoulder n., will bear with sufficient pressure against the inner side of the plate D, to prevent the slats from casually turning.

By this improvement the rod C, does not obstruct the light in any degree as the ordinary rods, and the slats are securely connected to the rod, they are not liable to become detached as in the usual mode of connection where staples are used. The slats also when their tenons become worn, cannot be moved casually, they will remain in the position in which they are placed in consequence of the friction produced by the spring c.

Another and important advantage is that the rod C, being Hush with the stile a, it cannot when the blinds are closed interfere with the window sash, as is frequently the case with the ordinary blinds especially when applied to frame houses, in which the window casements generally have narrow stiles and the blinds when closed brought quite near the sashes.

am aware that the rods of blind slats have been connected to the ends of the slats and arranged in various ways. A patent for instance was granted to L. S. B. Ellithorp, June 26th, 1855, for an improvement in window blinds in which the tenons of the slats were forked and the rods connected to them. A patent was also granted to T. Christian March 2d, 1858 for improvement in window blinds in which pulleys were attached to the ends of the slats. Both the cases above referred to diier essentially from mine.

I do not claim broadly operating the blind slats by a mechanism connected with one end of them, nor do I claim broadly a rod attachment at the ends of the slats, but,

Having thus described my invention what Stevens and I claim as new and desire to secure by Letslats B, as shown in combination with the 10 ters Patent, is, spring la, tted Within the mortise y', and at- 1. The rod C, fitted in one of the stiles a, tached to the stile a, the Whole being afrof the blind and provided With pins z', Which ranged substantially as and for the purpose 5 are itted in oblique slots e, in plates d, atset forth.

taehed to the ends of the slats, the parts ANDREW FERBER. being arranged substantially as and for the Witnesses: purpose set forth. J. L. BUCKLEY,

2. I also claim the rod C, attached to the MICH. HUGHES.
