PELATIAH OSGOOD, OF IVATERVILLE, MAINE, ASSIGNOR TO THE EAGLE SHADE ROLLER COMPANY, OF BOSTON, MASSACHUSETTS.

CURTAIN-FIXTURE.

SPECIFICATION forming part of Letters Patent No. 266,191, dated October 17, 1882.

Application filed January 28, 1882.

To all whom it may concern:

Be it known that I, PELATIAH ()seoon, of \Vaterville, in the county of Kennebec and State of Maine, have invented a new and useful Invention in Side-Cord Curtain -Fixtures, of which the following is aspecification.

The invention relates to a metallic packingbox and ratchet combined, and also a packing made of a fibrous material or ordinary wicking, for the purpose of holding a side-cord curtain-roller against the weight of the curtain, and a lip or tongue to hold the end of a knotted cord, as hereinafter described.

Heretof'ore side-cord rollers have been held by various kinds of springs and frictions secured to the roller or brackets in such a manner that they do not fully answer all the purposes t'or which they were intended.

The object of my invention is to provide a more perfect mechanism in the construction of a side-cord fixture, by which the roller shall be held against the weight of the curtain by the use of the packing-box and packing against the end of the roller, and also a lip or tongue to hold the cord.

In the accompanying drawings similar letters of reference indicate like parts.

Figure 1 is a longitudinal section, showing the roller in a completed state as it is hungin the bracket when ready for use, showing cord, packing-box, and ratchet with lever holding the cord. Fig. 2 is a transverse section, showingthera-tchet,packing-boxC,andfibrouspacking G. Fig. 3 shows asectional view ofpacking-box O and packing Gr. Figs. 4 and 5 show the same view of packing-box O as is shown in Figs. 2 and 3, except the packing G, instead of which a spring, H, is used for asimilar purpose. Fig. 6 shows the ratchet as connected with the bracket. Figs. 7 and 8 show the mannerofl'iolding the cord between the flanges of the roller by means of a lip or tongue cast upon the flange, as is shown in Fig. 1.

In Fig. .l, A is the roller.

B is the metallic end of the roller, which revolves in the packing-box O. This metallic box contains a fibrous material or common ordinary wicking, as is shown in Figs. 2 and 3, (indicated by letter G.)

(No model.)

E is a screw passing through the metallic box into the roller.

F is the lever which holds the cord, and is attached to the bracket, so that the projection or pawl upon the lever, as is shown in Fig. 6, drops into the ratchet D upon the packing-box O, which prevents the boxfrom turning in the revolving ot' the roller as the curtain is being drawn down. By tightening the screw the packing contained in box 0 is firmly pressed against metallic end B, which causes a sufficient friction to hold the roller against the weight of the curtain at any point desired. By drawing the cord out from the curtain the pawl of the lever F is lifted from the ratchet D, which allows a free movement of the roller, so that the weight of the curtain revolves the roller and carries the curtain to any part ot' the window. The pawl on the lever is then allowed to drop into the ratchet I), which holds it and prevents the roller from turning.

If desired, the curtain can be drawn down while the pawl is in the ratchet D, the roller end revolving against the packing in the box, while the box is held by the pawl.

It will be seen that by this method of operation a curtain of any weight can be used upon the same roller.

L is a lip or tongue cast upon one of the flanges of the roller. Between these flanges the cord that operates the roller is fastened. The ordinary way in which the cord isheld is by drawing one end of it through ahole made in the flange close to the roller. A knot is then tied in theend of the cord to prevent it from pulling out. The object of this lip or tongue L is to hold the knotted end of the cord without being obliged to pass it through a hole in the flange, as in the former case.

Fig. 7 shows in section the metallic. lip or tongue L, with the knotted end of the cord N passing under and behind it. The cord can he slipped in or out sidewise when desired.

Fig. 8 is a section, looking across the roller near the top. This shows the cord N passing under the lip or tongue L. This lip or tongue, if desired, can be cast or placed between the flanges of the roller, and will serve thesame purpose to hold the cord as if cast upon the flanges, as herein described, and shown in the drawin gs.

I-Iavingdescribed my invention, what I claim as new, and desire to secure by Letters Patent, 1s

1. In combination with a side-cord curtainroller, a metallic packing-box and ratchet, made or cast in one piece, and adapted, with its inclosed packing, to hold the roller frictionally, whereby either the box may beheld from turning by a pawl engaging the ratchet, or the curtain may be drawn down by force applied to overcome the friction of the box, or by releasing the ratchet the box may revolve with 15 the roller, substantially as described.
