Letters Patent No. 111,367, datedFebruary 21,1971.
IMPROVEMENT INv CUTAlN-FIXTURES.
The Schedule referred to in these Letters Patent and mak-lng part of the lame.
I. PHINEAS W. PHILLIPS, of Salem, in thecounty of Essex and Stateot' Massachusetts, have invented certain Improvements in Curtain-Fixtures, of which the following is a specification. A
My invention relates to that form of curtain-fxture in which a coiled spring, in connection with a weight, is used tobalance a shade; and consists in certain devices by which the production of the shade-roller, lin its various parts, is cheapened, simplified, and made more durable in working.
The drawing represents, in'
Figure 1, a partial sectional View of the shaderoller, showing section of cap, wire shoulder, and step.
Figure 2 is a plan view of flanged cap.
Figure 3 is an elevation of the roller, showing the slot.
Figure 4 is a section of shade-roller on the line A B of figs. 1 and 3f Figure 5 is a sectional view of shade-roller, showing the step inserted in the wooden' plug.
Similar letters of reference indicate alike parts vin all the iigures. v Y
A represents the hollow roller, which is made of' wood.
B represents the sha-ft upon which the spring is wound.
O represents the spring which balances the shade.4
One end ofthe spring C is attached tothe shaft B. The other end is bent outwardly, and' secured and retained in the slot D, cut in the wooden. roll A.
The inner end of the shaft B revolves in the step or bearing F. rlhis step is made of metal, struck up by dies into the proper form, and then driven into the wooden 4plug F, which has previously been hollowed ont so as to receive and retain it exactly in the center of the plug. This plug is then driven into and through the hollow roll B to the position shown, where it is properly Secured.
By this means the shaft is certain to be placed in the center ot' the wooden roll A.
rlhe cap G is made oi' metal, with two an'ges, which are made to inclose and hold the end of the hollow roll A, which is very thin and yliahle'to be crushed or broken, accidents which the flanges entirely prevent. l- The flanged cap may be cemented' to the end of the roll to hold it in place. f
The 'end of the shaft `B nearest the end of the roll has a coil of wire, H, ,Wound tightly` around it, and secured to it so as to form a shoulder, against which' 4the flanged cap G presses tightly, thus retaining the and set forth.
The slot in theend of the shade-roller for receiving and retaining the spring should be very narrow andV near the end. The flanged cap closesthe end of the slot and prevents the end of the spring from Working out.
- It is important, in the class of fixtures -which this form of construct-ion represents, that the inner end bearing should coincide with the axis of the cylindrical roll, and the device shown is an effective and economical method 'of securing this result. The shade also runs easier than when the shaft is sim ply driven into the wood, where it soonV wears loose.
In order not to have toolarge a hollow roll, which wouldbe objectionable, the end ofthe roll isrequired to be very thin, and the risk of injury by splitting and breaking is overcome by the flanged cap shown, which incloses and protects the end of the.'roll.'
The plan for retaining the end of the shaft `in its place in the roll by means of the coil of wire, has the merit of heilig the cheapest method of accomplishing this result. Byany other method it would be necessary to use a' larger shaft, andturu or mill down the end projecting through the cap. This is rendered unnecessary by the use of the vdevice shown.
I claim as my invention- A shade-roller, in which the following elements are combined, viz: A iianged metal cap, a hollow slotted roll, and metal step, made and used substantially as described, the whole operating together in the manner and for the purpose set forth.
, I. W. PHILLIPS.
