Specification of Letters Patent No. 12,150, dated January 2, 1855.

. To all whom t may concern:

Be it known that I, PETER H. Nimes, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new' and useful Improvement in Curtain or Vindow Shade Fixtures; and I do hereby declare that the same is fully described and represented in the following specication and the accompanying drawings, let-ters, figures, and references thereof.

Of the said drawings, Figure 1 denotes a front view of a curtain roller and its brackets constructed with my improvement; Fig. 2, is a longitudinal section of the same; Fig. 3, is an end view of one of the brackets.

The roller which is shown at A, is provided with but one head, B., that end of the roller opposite to that fixed on the said head being intended to be inserted, supported and made to revolve in the round socket a, of the bracket C.

The pulley head B, consists of a socket b (for the reception of one end of the roller) a pulley barrel c, and a flange or disk d. This barrel, c, which is cylindrical is made to enter, rotate and slide in a round chamber, e, formed in the other bracket, D. The whole pulley head is supported and made to revolve on a stationary pin E, projected from the bracket. Enveloping this pin is a helical spring, F, which is arranged in the chamber, e, and rests at one end against the end of the said chamber, while atthe opposite extremity it is made to enter a smaller chamber, g, bored in the pulley barrel asV seen in Fig. 2, the'object of this last chamber being to enable a larger spring to be employed than could be used were the barrel made solid. That end of the curtain roller which is inserted within the socket', b, is bored axially as seen at h, and far enough to allow the barrel, c, to be moved back into the chamber, e, to the extent suflicient for releasing the curtain roller from the bracket, C. When the flanch or disk, a3, of the pulley is arranged at the proper distance from the bracket, D, the end of the pin, E, is to be upset, or such pin may be provided with a head z', such as will preserve the pulley on the pin against the pressure of the spring.

My object in the above described construction and arrangement of the operative parts applied to the roller and t-he bracket, D, has been to so combine them that they may be entirely separate from the stick or roller, and yet hold together, whereby they may be so independent of the roller as to constitute a marketable fixture which could be sold by hardware dealers and readily applied to any stick or rollers-curtain fixtures as generally found in the market having the roller connected and sold with them.

In various curtain fixtures, the spring is.. either placed in the socket of that bracket which is opposite to the one by which the pulley is supported or it is disposed within the body of the curtain roller and made to act against the journals of such roller. In my improved fixture the spring is arranged within the other or pulley bracket and on a stationary pin and is not in any respect in contact with or within t-he'roller. This enables me to not only attain the advantage above stated, but another viz., that of the direct pressure of the spring in keeping the pulley in place on the end of the roller and preventing itfrom working or slipping of? as it is liable to when the spring is not in contact with the head. The spring is entirely encased so as not to be liable to injury or loss. Other advantages will be obvious to upholsterers or those skilled in making and applying curtain fixtures.

Although the spring when applied to the opposite end of the curtain roller operates in some cases to keep the roller in the pulley socket, yet it does not bear directly against the pulley. "When the spring is placed at the pulley end of the roller and operates against a sliding journal, it has no tendency to maintain the pulley head or socket on the roller and such is liable to work loose and slip off' the roller- A It is therefore to a pulley constructed with its body'c, ymade to slide into a socket, e, of the bracket, that my improvement is specially applicable.

I am aware that .it is not new to support the pulley on a pin fixed in and projecting from a bracket; nor to make the pulley with but one flange or head, CZ, and so as to have its barrel, c, work in a chamber, e. I therefore do not claim such, but

What I do claim is- 1. Arranging the spring in that chamber of the bracket, in which the body of the by an advantage as above stated may be 1o pulley slides. obtained.

' 2. I do not claim making the pulley body In testimony whereof, Ihave hereunto set with a chamber for the reception of a spring my' signature this first day of November 5 or for any other purpose, but A. D. 9.854.

What I do claim is so arranging the seci :PETER H. NILES. ondary or lesser chamber g, with respect to Witnesses: the chamber e, that the spring F, may eX- p R. H. EDDY, tend into both chambers as specied, Wheref j F." I. HALE, Jr.
