JAMES F. SNAPP, OF GARZA, TEXAS.

CURTAlN-FIXTU RE.

SPECIFICATION forming part of Letters Patent No. 506,344, dated October 10, 1893.

Application filed April 23, 1893. Serial No. 472.211- (No model.)

To to whom it may concern:

Be it known that 1, JAMES F. SNAPP, a citizen of the United States, residing at Garza, in the county of Denton and State of Texas, have invented certain new and useful Improvements in Curtain-Fixtures; and I do declare the following to' be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and t0 the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in window shades and means for supporting and operating the same.

The invention in the present instance resides in the peculiar combinations, and the construction,arrangement and adaptation of parts, all as more fully hereinafter described, shown in the drawings and then particularly pointed out in the claim.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which Figure 1 is a front elevation of my improvements. Fig. 2 is a perspective view of the bracket at one end of the bar. Fig. 3 is a longitudinal section of the upper roller. Fig. 4 is a perspective detail of the cap at one end of the upper roller, showing also the gravity pawls.

Like letters of reference indicate like parts throughout the several views.

Referring now to the details of the drawings by letter, A designates the upper roller which is provided at one end with a pintle or spindle a while at the other end there is a cap piece A within which is arranged the pawl mechanism.

B are the pawls pivoted on the end of the roller and adapted to engage the notches b in the pintle or spindle O rotatably mounted in the end of the roller and having a squared portion to engage in a bracket in' the usual manner: there is no spring in this roller. The pintles or spindles of this roller are journa-led in the usual manner in brackets D which may be secured to the window casing in the usual way, or they may be secured to a bar Ewhich bar is provided with holes 01 for the reception of screws or other means whereby it is secured in place.

F is a bar somewhat longer than the shade roller and upon each end of this bar is sleeved a sheet metal bracket and sleeve G which is bent to embrace the end of the bar to which it is secured in any suitable manner, and provided at the outer end with a depending bracket or lugfand with a piece f which covers the end of the bar to which it may be secured in any suitable manner. In these depending lugs or brackets are journaled the ends of the spindle g of the shade roller H which may be of any well known form of spring roller. The bar F is supported from the upper roller by means of the cord, ribbon or chain I which has its ends secured to the said bar near the ends thereof as shown at '8, and this cord, chain or ribbon is wound upon the upper roller and is secured thereto at points about midway the length of the cord as seen at I it is so arranged that as it winds upon the roll upon one side of its points of connection therewith it unwinds therefrom upon the other side of its points of connection; the cord is bent upon itself at its center andthe depending portion depends from near the center of the length of the upper roller. As it winds upon the center it unwinds from near the ends and the bar and shade are lowered; as it unwinds from the center it winds upon the ends and the shade and its roller and the bar are raised. The bar and the shade are automatically held in their adjusted positions by the pawls. To throw the pawls out of engagement with their notches it is only necessary to give the cord a sudden jerk which will throw the pawls out and the bar is free to be lowered by its own weight. It is wound up against its weight by the cord.

Modifications in detail may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages; for instance, the bar E may be entirely omitted as hereinbefore stated, and any means which may be employed as a substitute for said bar, I should consider as the equivalent thereof.

In testimony whereof I alfix my signature in presence of two Witnesses.

JAMES F. SNAPP.
