IMPROVEMENT IN CURTAIN-FIXTURES. I

Specification forming part of Letters Patent No. 122,356, dated January 2,1872.

To all whom it may concern: y

Be it known that I, CHAUNCEY BUCKLEY, of Meriden, in the county of New Haven and State of Connecticut, have invented a new Improvement in Curtain-Fixtures 5 and I do hereby decla-re the following, when taken in connection with the accompanying drawing and the let ters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawing constitutes part of this specification and represents, in

Figure l, a side view of a portion of the roll with the iixture attached; Fig. 2, an end view; Fig. 3, a" longitudinal central section, enlarged to double the usual size; andin Fig. 4, a modification of the friction-plate and ratchet.

This invention relates to an improvement in the curtain-fixture patented to L. L. Sawyer July 11, 1871, of which this applicant is one of the assignees; the object being to attain the same result by a cheaper construction, and one less liable to get out of repair; and it consists in the construction of the pulley, upon which the cord is wound, from plates of sheet metal secured together and to the roll, in the manner as fully hereinafter described 5 and also in the arrangement of a disk upon the ratchet, whereby the friction is made adjustable and outside the curtain-roll.

A is the curtain-roll, formed from wood in the usual manner. The pulley is formed from two circular plates or disks, B C, cut from sheet metal, and may be of a thickness to sustain themselves, or may be beaded in the process of stamping, whereby a thin metal may be used.

- Centrally between these two plates a barrel, D,

is arran ged,the length of which determines the space between the two plates, and centrally through the barrel and two plates is arranged a barrel, E, of square or irregular form, as seen in Fig. 3, the perforations through the head corresponding, so as to tit closely on the barrel E. This barrel E is of suiiicient length to extend into the roll and thus prevent the pulley from turning independent of the roll. Through this barrel a screw, F, is. passed into the roll, the head bearing directly or indirectly upon the outer disk or plate C, and thus securing the parts of the pulley together and to the roll. H

is the ratchet which holds the curtain when rolled up, as in the patent of Sawyer before referred to. This ratchet, being loose on the screw or spindle F, is held with sufficient friction to support the curtain. This friction I accomplish by a disk or plate, I, outside the ratchet, and

to form a bearing for the roll I form a shoulder on the screw by placing thereon a sleeve, L, or otherwise,so as to form a space between the disk and the head. This bearing upon the disk presses the disk onto the ratchet, the pressure being adjusted by turning the screw more or less hard down to adapt the tiXture to curtains of different weight, heavy curtains requiring a greater friction than light curtains. While this ratchet prevents the curtain from falling, the

friction is only to such an extent as to allow 'the curtain to be drawn down in substantially the saine manner as in the Sawyer patent before referred to.

I have represented the disk as placed outside the ratchet, the two being separate and detached pieces; but the saine object is accomplished by having the disk and ratchet in one piece, as in Fig. 4, lugs projecting from the edge of the disk outward, as at a, to serve the purpose of teeth to engage the pawl. I there-4 fore do not wish to confine myself to the disk and ratchet as detached parts.

I claim as my invention- 1. A pulley for curtain-tixtures, consisting of the two plates B C, arranged upon the barrel E, and secured in position by the screw or spindle F passing through the said barrel into the roll, and the head bearing directly or indirectly upon the outer plate.

2. In combination with the roll A and a pulley iXed to the end ofk the roll, I claim the frictionplate or disk I outside the said pulley, and the friction made adjustable bythe screw F, substantially as set forth. whether the said friction-plate be separate from or a part of the ratchet.
