TQ. ALL WHOM`ITMAY CONCERN: V
Beit known that I, WILMER D. GRIDLEY, of NewBritaimcounty of Hartford, and State of Connecticut, have invented certain new and useful Iinprovements in Curtain-Fixtures; and to ena-ble others skilled in the art to make and use the same, I will proceed to describe itslconstruction and operation by referring to the drawings, in which the same letters indicate like parts in 'each of the figures.
The nature of` this invention will be understood from the specification and drawings, the object oi' which is to Vsecure more complete c pntrol of the curtain, and allow it to be raised and lowered uniformly and easily. In the accompanying drawings- Figure 1 is a face view .of the device as in use.
Figure 2 is a friction-device, through which the curtain-cord passes, which holdsthe curtain in any desired position.
a is the curtain, secured upon a roll in thev usual way. c are the brackets, also secured to vthe jumb or casing in the usual way. d is aspool, to which one end of the curtain-cord e is secured, and winds up and unwinds, to raise and lower the curtain. -,F is a flange-socket case, secured to the casing by scrcwsi' 7L is a pad, made of any suitable inaterial, placed at the base of the socket. z'is a spindle-pad, having a spiral spring, la, arranged upon said spindle, one end of which takes its bearing against the pad z', and the opposite end against the head of the socket-case f, while the spindle t" extends through the knob n, and headed. This socketcase is provided with orifices o o, whichV allow the cord e to pass between the friction-pads 7L i. The spring 7c, acting against the pad z', causes a uniform pressure or friction upon thc cord e sufticicnt to hold the curtain in any' desired position. i v
Thus it will be seen that, by Vpulling the cord e,` the curtain may be rolled up,'and by pulling the tnssel t,
the curtain may be drawn down in the usual way, and,'by the use ofthe friction-device, the curtain can be held in any desired position.
I believe I havethus shown-.the nature, construction, and operationof thisinvention so as to enable others skilled'in the art to make and use the same. l
' What I claim, and desire to secure by Letters Patent as anew improved article of manufacture, isf- A curtaimfriction bracket, consistinglof the socket-casef, friction-pads 7i z', spring c,`..knob nfsubstantially as described. Y I 1 vWlLltIER D. GRIDLEY. [1.. s] Witnesses:
