Letters .Patent N 100,341, dated March 1, 1870.

menovsn commu-FIXTURE.

The Schedule referred to in these Letters Patent and making part of the lame.

To all whom lt muy concern:

Be it known that we, JAMES TURNBULL and WIL- LIAM TURNBULL, of the city of Vancouver, in the county of Ulaik, in the Territory ot' Washington, have invented a new and improved Curtain-Fixture;

and exact description ol' the saine, reference being had tothe accompanying drawings, and to the figures and letters ot reference marked thereon. f

Ourl invention consists ot` a cylinder or pipe, O, in which is placed a pulley, A.

Figure 1 shows the construction of a variety, where the. cap I screws on at either end.

Figure 2, the pulley A, stem F, and center.and tangs G. v

Figure 3 shows a construction where lugs, K, are used in fastening the pipe O to the wall, in their ends being screw-holes.

Figure '4 shows ,a piece of metal intended to be placed on the edge ot' the curtain.

Ihe curtain-cord passes around the pulley A, the pulley being in the lower turnot' the cord.

Ihis pulley A is peculiarin having a boss on either side, seen at G, tig. 2, and ou plan at A, lig. 1 The diameter is almost as great as at the inner part of theppc C.

The pipe C is provided with a slot, B, in which A rises or falls freely, it being open at the lower end in order to put in the pulley.

rlhe bosses described above prevent the pulley from falling out ot' the slot.

Around the stom F a spiral spring, D, is coiled, which presses the curtain-cord in the lower turn through the. pulley A, and its center and tangs G, all ot' which is within the pipe C except a 'small partof the periphery ot' the pulley A, seen at a, tig. 3.

The ends ot' the pipe may benishedin many ways; the inventors u sh to describe three ways of so doing: First, by a cap, I either inside or outside the pipe C, fastened by screws around its circumference; second, bya cap fastened by a pin, rivet, or screw passing through the shell in the direction ot'the diameter; or, third, by a plug of wood introduced on the inside of the pipe, or on the outside, as in the manner of the metal one described for No. 2.

In addition to the lugs K, the inventors describe another method of fastening the'pipe G tothe jamb. viz:

A large hole, H, is bored through. thc outside of the pipe ou each end, (see gs 1 and 3,) large enough to allow a screw-head to pass through tieely. The inside 'running through the eye-hole `in A, make a center therefor; or the tangs may be drilled, and a rivet put through. An annular groove, E, may be made ou the stem F.

The piece L, lig. 4, is made of a flat piece ot metal, through which holes are pierced for sewing or attaching to the'cloth, and at the side is a projection, through which is a large hole, large enough to allow the curtain-cord J to pass freely. or twisted, s0 that its face or flat part is at right augles to that on the curtain. This piece might be cast instead of being made in this way. n

v Its use is for this purpose:

When the window is up, the wind sometimes dashes the curtain and stick violently against the wall, marring it or objects near, and damage is done sometimes to other windows; `the curtains get to rattling' and break the glass. 1t is also useful for another purpose, that ot' keepingthe curtain straight on the roller as it is raised or lowered.

The reason for using a spring in connection with the cord-pulley, is that all cordage is slack at times, and tense at others, as it may be dry or, damp, and by the means described above, these dililculties are overcome, and the curtain is always'iu adjustment for use.

Claim. v \Ve claim the slotted pipe C, the spiral spring I), stem F, tangs G, pulley A, lugs K, and holes H; also piece L, and manner ot' making cap I, when used in combination as described, and for the purpose set forth.
