PATENT OFFICE.
ROBERTV J. BETTS, OF MILTON, DELAWARE, ASSIGNOR ONE-HALF'TO THOMAS A. OONNOLLY, OFKWASHINGTON, DISTRICT OF COLUMBIA.
WINDOW-SHADE FIXTURE.
SPECIFICATION forming part of Letters Patent N o. 378,079, dated February 21,1888.
Application filed May 26, 1887. Serial No. 239,431. (No modelf) To all whom it may concern:
Be it known that I, ROBERT J. BET'rs, a citizen of the United States, residing at Milton, in the county of Sussex and State of Delaware, have invented certain new and useful Improvements in Window-Shade Fixtures; and I do hereby declare the following to ,be a full, clear, and exact description ofthe invention, refer ence being had to the accompanying drawings, which i'orm part of this specification, in which- Figure 1 is a perspective, partly broken away, showing my invention. Fig. 2 is a perspective of roller and cord. Fig. Bis a vertical sectional view of the bracket and roller.
My invention has relation to shade-fixtures, and has for its object to provide a construction whereby, lby the employment of a single cord in connection with a peculiarly-constructed bracket, a shade may be rolled up and down and held in any desired position.
My invention consists in the peculiar construction and combination of parts,hereinafter fully described and specifically claimed.
Referring to the accompanying drawings, A represents the top piece of a window-frame to which my invention is applied. Y
Brepresents a shade-roller, and C a shade attached thereto.
D and E are brackets in which the roller B has its bearings, said brackets being secured to the frame-piece A. The bracket D may have any suitable bearing for the reception of the end of the roller B, or for a journal or pintle, b, in the end of said roller. I have illustrated said bracket D as having a vertical slot, d, which is open at the top, but closed at 'the bottom, the journal or pintle being designed to rest -upon the bottom of said slot. The bracket E affords a bearing for the opposite end, b', of the roller B. Said bracket is formed with a vertical slot, F. Said slot is elongated and tapering, being widest at its top and narrowing as it descends. When the end b of the roller B is in the lower portion of the slot F, it iills said lower portion and wedges or binds between the sides of the slot; but when it is in the Iupper portion of the latter it is free to revolve therein, there being ample space left for that purpose.
G represents a cord which passes through an opening,f, in the front of the bracket E, thence around the end b of the roller, and thence through another opening, f', in said bracket E, passing thence downwardly back of the bracket E or between it and the board A, as shown, a slot or recess, f2, being madeA in the back of the bracket for the passage of said cord. A
In operation the cord is pulled by one of its ends or pendants to revolve the roller in one direction, and is pulled by the other end or pendant to revolve said roller in the reverse direction. or pulled, it inthe first place elevates the end of the roller out of the lower portion of the slot and then rotates the roller in the direction of the draft. on the roller 4either in front of the latter, as illustrated in the drawings, or back of the same, and in either case the cord will operate in the same way. Upon cessation of draft on the cord G the end of the roller will drop down in the lower portion of the slot F and bind therein, the shade remaining at any position to which it has been adjusted.
The construction described is very simple and comparatively inexpensive, while at the same time it is Very effective and durable.
The brackets may be made either of wood or of metal, and may be readily applied by unskilfullhands to the purpose for which they are designed. l The threading of the cord through the openings f f and its winding around the end of the roller may also be readily done without difficulty or special skill. If the shade should be heavy or weighted, the cord may be passed twice around the end of the roller in order to secure a better hold thereon; but if ordinary light shades beused it will be sufficient to have the cord pass vonce around the roller. Y
It will be noted that the cord passes directly around the end of the roller', and hence that no metallic pulley is required, thus permitting the iixture to be constructed at very slight'expense. f What I claim as my invention is as follows: l. A shade-tixture bracket, E, having a vertical conoidic slot, F, in its side, said slot taf peringas it descends, substantially as shown and described. Y
When the cord is so .drawn upon rlhe shade may be wound IOU the roller tting in a couoidie slot in the side of the bracket, and thereby preventing the roller froml being turned by the pull of the 15 shade-Weight.
In testimony that I claim the foregoing I have hereunto set my hand this 30th day of 2. The combination, with shade-roller B and bracket E, having slot F and openings ff above the roller B, of the cord G, passing through said openings and around the roller,
5 whereby a pull on the cord will raise the end of the roller, substantially as shown and described. April, 1886.
3. In Window shades and fixtures the combination, with the shade-roller and shade, of ROBERT J' BETTS' ro the cord G, passing over the end of the roller Witnesses:
' R. DALE SPARHAWK,
WILL H. POWELL.
