SPECIFICATION formingpart of Letters PatentfNo. 722,912, dated March 17, 1903.

Application iiled October 17, 1902. Serial No. 127,708. (No model.)

To all whom t may concern: A

Be it known that 1, CHARLES A. SoHE1F,a citizen of the United States of America, residing at Wilkinsburg, in the county of Alleghenyand State of Pennsylvania, have invented certain new and useful Improvements in Window-Shade Adjusters; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, which forma part of this specification.

The object of my invention is a device for windowshades, being a Vmethod of raising and lowering the same by means of cords, as will be hereinafter more particularly described. K

In the accompanying drawings, forming a part of this specification, Figure l is a window-frame shown in perspective and having my device attached thereto. Fig. 2 is a view of a window-frame, showing my device thereon with the shadelowered part way down the frame. Fig. 3 is an edge view of the cord side of the window-frame with my device shown thereon. Fig. et is a plan and edge view of my shade-hanger for the iXed spindle of the roller. Fig. 5 is the hanger used in Vmy device for the rotatable spindle of the shaderoller. Fig. 6 is a sectional view of the double reversible pulley used by me in my device as attached to the window-frame. Fig. 7 is an edge view ot' the cord-fastening device.

In the drawings, A A designate the window-frame.

A is the window-pane.

C is the cord that passes across the window-frame, (seen in Fig. 1,-) over the pulley, to the hanger C. (Seen in Fig. 4.) C2 is the hanger at the opposite end of the -roller B. j

These hangers are differently formed, as will be seen by reference to Figs. 4 and 5. The hanger C has a slot c, terminating in a circular opening c', tor fastening and securely holding the end of the cordC. vLower down on this hanger 'is the openingc2 to` receive the non rotatable spindle of the Vshadefroller. c3 cB are springs made integral with the hanger C and are so formed that when the spindle is placed between them it is held securely therein and prevents any rotation. The other hanger C2 has the slot c4, ending in the circular opening c5, and the opening c6 to receive Acord straight down a short distance.

the rotatable end of the shade-roller, the opening c5 and slot c4 being for attaching and securely holding the end of the cord C..

C4 is a fastening device for the cord C5, having the slotted opening to receive said cord and lock the shade-roller at any desired position on the window-frame. This fastening device is securely attached tothe windowframe on-the right-hand side by small nails at the lower edge. n ,Y

D is the pulley-frame, secured to either side of the window-frame at the top, as seen in Fig. l, by means of smallnails.v These pulleys are made double, so as vto be used on either side-of the frame and to allow for a re- -V turn passing of the cord C, as seen in Fig. 3.

The hubs of these pulleys are bored out to receive a pin or nail to serve as an axle and hold them in place. In these pulley-frames D, I provide openings d5 d5 forV the purpose of reversing the pulley Dwhen itis placed 0n the under side of the window-frame at the top, which is often desirable. To do this, the pin d3 is inserted through theholes d5, then through the pulley, and into the window-frame. The cord C is irst attached to the hanger C', then passed up and through the pulley on the left side of the window-frame, then across and through the groove in the pulley nearest the window-frame, then down along the frame to a point where it is desired to locate the fastening device C4. A loop in the cord is then made and the end'carried upand through the outside `groove of the pulley, where itis securely fastened to the hanger C2. A piece of the cord of desired length having first been cut, from Ythe cord G is here -attached to the loop above mentioned and then passed through the fastening device C4. lThis portion of the cord I have designated as C5 and the loop as c7. My device is then ready to receive the shaderoller, which maybe yeasily and quickly attached.l When vit is desired to lower the shade, all that is necessaryby means of my device isteV release. the cord vfrom the .fastening device CA1 bypulling the end of the The cord being thus released will permit the shade to drop to any desired height on the window-frame by its own gravity, Where it can be stopped at will and held in place simply by the operator giving the cord an up- IOO ward movement, whent will enter the groove in the fastening device C4 and lock the shade in position. By this simple movement it is readily seen that the shade can be raised and lowered to any desired height on the window, thusaffordinglightandventilation. Bythese simple devices, constituting my invention, I am able to accomplish the same results noW claimed by more complicated inventions and at a greatly-reduced cost to the inventor and purchaser.

The frame D for receiving the double pulley D therein is fastened by nails d4, While the pulley is adjusted to the frame D by a nail d3. The pulley D has the annular grooves d2 d2. Before adjusting the ordinary spring shade-roller B to the hanger C2 it is necessary to remove the rotatable spindle and in its place substitute an ordinary wire nail having a head, leaving about a quarter of an inch projecting out, where it will rest securely in the groove portion c6.

Having thus fully described and shown my invention, what I claim as new, and desire to secure by Letters Patent of the United States,

'reame l. In a Window-shade adjuster, the hanger C having the spring-Wings c3; slot c; slot o2 and opening c in combination with the cords C C3 and hanger C2 substantially as described and shown.

2. In a window-shade adjuster the hangers C and C2 each having the opening formed with the reduced slot and the hanger C' havspring-Wings c3; cords C and C3 in combination with the pulleys D; frames D and holder C4, substantially as described and shown.

3. In a Window-shade adjuster the combination of the brackets, the pulleys each having a pair of grooves, the pair of hangers each having an opening with reduced portion and one of the hangers having a pair of spring- Wings, the shade-roller mounted in the hangers and the cords connected to the hangers and passing over the pulleys.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing Witnesses.
