IMPROVEMENT IN METALLIC BLINDS' FOR wmoows, 8w.

Srpecification forming part of Letters Patent No. 34,l62, dated January 14, 1862.

To all whom it may concern.-

Be it known that 1, CHARLES NEER, of Albany, in the State of New York, have invented, made, and applied to use a certain new and useful Improvement in Metallic Blinds; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of my said invention, reference b'eing had to the annexed drawings, making part of this specification, wherein- Figure l is a plan of part of the-blindframe. Fig. 2 is an elevation of the upper end of a blind fitted with my -improveinent Fig. 3 is a vertical cross-section showing the upper and lower ends. of the blind, and Fig. 4; is a sectional plan at the linens 217.

Similar marks of reference denote the same parts.

My said invention relates, firstto a metallic strip receiving the tenons of the blind, applied to and combined with a metallic frame in a peculiar manner; second,to the construction of metallic slats applied in said frame, and, third, to the manner of fastening the slats.

In the drawings, a a are the vertical stiles made from fiat wrought-iron bars, and connected to each otherv by the cros bars or rails b I). These stiles a a stand across the ends of the rails b b and present their edges at the sides of the blind. The rails I) hate connected'to the stiles either by passing the end of the-rail through a mortise in the flat stile, as shown at l 1, or else by bending the end of the rail at right angles, as at 2 2, to form a flange and attaching the stile by rivets. This method of forming the metallic frame for blinds enables me to use comparatively light iron, and at the same time attain great strength and stiffness in the said frame,,fo'r the wide cross bars or rails b I) prevent the blind from sagging, and the vertical stiles render the blind stiff lengthwise of the frame;

0 c are strips of thin'sheet-iron bent or folded into the shape represented, and perforated with holes at the proper distance apart for receiving the tenons of the blind-slats, and these strips 0 c are kept from the stiles a sufficiently for introducing said tenons by means of wooden strips 3 and rivets passing through the three thicknesses secure the I the tenons; but I prefer that said strips 0 be on the inside of the stiles, as seen in Figs. 2 and 4.

The metallic slat cl, Fig. 3, is similar to that shown in my paten't'of June 15,1858; butmy improved slat eis shown in Figs. 2 and 3, and is formed of a metallic sheet attached at its lower edge by the cross-wire 4, at which point it turns, and the upper ends of the slats swing open, and are connected by a vertical rod f, (the same as in my aforesaid patent.) In this form, however, the blinds would be apt to drop open. I therefore provide the disk or washer 5 at one or both ends of one or of sev: eral of the slats, said washer setting over the wire 'and having-a groove to take the edge of the slat, so'that the two turn together, and 6 is a perforated spring setting over the afore said rod 4 and giving the required friction against the washer 6 to keep the said slats from falling and retain the same in any position to which they may be turned. The slats may shut against the flange 10 of the strips 0 c. The metallic blinds, formed as aforesaid, are to be mounted on hinges of any desired character, and the wooden casing usually surrounding the window-sash, and to which the said metallic blinds will be attached, is to be protected from fire by the metallic lining g and airspace i. This metallic lining is to be attached at the rabbet next the blind by nails, as at 7, and kept from contact against the face of the wood by nails 8 S, that project from the casing, while the nails 9 9, that pass through perforations in said metallic lining, retain the same in place. By this arrangement an air-space is left between the iron and the wood-work, effectually rendering the same fire-proof.

To prevent the metallic slats being turned,

1 make 'use of a vertical bar it, united by hinges 11 to thestiles e. and so fitted as to be .by the cross bars or rails b b, the parts receiving the tenons of the blind-slats, as set forth.

2. The metallic slats e e, attached at their lower corners and provided with the disk 5 and spring 6, for the purposes and as setferth. 3. The bars h, hinged to the blind-frame, as set forth, so that they can be turned against the slats to keep them shut, as specified.

In witness whereof I have hereunto set my signature this 28th day of January, 1861.

CHARLES NEER.
