Application filed August 14, 1919. Serial No. 317,488. .7 l

To all whom it may concern:

Be it known that I, 'PIETRO BIASUOCI, a citizen of the United States, residing at Yukon, in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Window-Shades, of which the following is a specification.

The primary object of the present invention is to provide a window shade that is capable of being raised and lowered'to the desired points and effectively retained in adjusted positions to the exclusion of spring devices that are usually employed in window shades of ordinary construction, the window shade being raised and lowered by pull cord devices associated with the curtain and shade roller bar.

A further objectof the invention resides i in the provision of a springless shade roller that is positively raised and lowered by in- I dependent pull cord devices, the shade stick cooperating with the bracket bearings of the shade roller for limiting the rising movement of the shade. I

'With the above and other objects in view, the invention consists in the novel form, combination and arrangement of parts herein fully described in connection with the accompanying drawing and in which like reference characters indicate similar parts throughout the several views.

In the drawings, 7

Figure 1 is a fragmentaryview of a portion of a window frame with the present invention in operative position thereon,

Fig. 2 is a side elevational view of the bearing bracket for supporting the ratchet end of the shade roller bearing partially shown in section and illustrating the spring pressed plunger for engaging the, ratchet roller to arrest movement thereof and Fig. 3 is a vertical sectional view through a portion of the bracket shown in Fig. 2, 7

illustrating in side elevation, the reduced end of the shade roller bearing.

Briefly described, the present invention aims to provide a window shade that is adapted to be raised and lowered by independent devices to the exclusion of spring elements, 2'. e., a spring associated with the roller bearing for restoring the same to its initial position or for elevating the shade. In the present device, the roller bearing for the shade extends from opposite sides thereof and is rotatably mounted in bearing brackets, a spring pressed plunger being asi sociated with one bearing adapted to seatin spaced sockets formed on the periphery thereof while a pulley is attachedto the other projecting endof the roller bearing and is adapted to have onee'nd of accord secured thereto which cord will be' wound upon the pulley when the shade is lowered,

andit being desired to elevate the shade, it is only necessary to pull the cord wound upon the pulley to rotate the shade-roller I and wind the shade thereon during which time the spring pressed plunger ratchets over the sockets in the roller bearing and as will be clearly understood, the height of y set position. It is also contemplated that the stick carried by the window shade cooperate with the bearing brackets to arrest the raising of the shade when the projecting ends of the window stick engage the brackets.

Referring more in detail to the accom- .panying drawing, j the reference numeral 5 designates a window frame having a' pair of brackets 6 and 7 secured adjacent the upper ends thereof, which brackets form bearings for the ends of the shade roller 8 shown inFig. 3, and upon which the .win-

dowshade 9 is secured, acurtain lObeing' centrally attached to the shade stickll by which the shade may be lowered, the opp'o' site ends of the stick 11 projecting beyond the sides of the shade as at 11' shown in Fig. 1.

The bracket 6 is shown more clearly in Figs. 2 and 3 and is provided with a cylindrical transverse opening 12 within which a metal bearing cylinder 13 is secured, the metallic cvlinder 13 forming a bearing for the metallic thimble 1 1 secured upon the reduced end 8' of the shade roller 8, the thimble being secured upon the shade roller end by a screw 15. As clearly shown in Figs. 2 and 3, the thimble and reduced end 8 of the shade roller are provided with cooperating sockets 16 into which the pointed end 17 of a plunger is adapted to seat, the stem 18 carried by the lower end of the plunger operating in a cylindrical socket or cut out portion 19 in the bracket 6 and being surrounded by a coil spring 20 extending between the plunger head and the lower end of the socket 18, to force the plunger upwardly through an opening in the bottom of the cylinder lt that registers with the flange recess 19.

The opposite end of the shade roller 8 projects outwardly of the bearing bracket 7 as shown in Fig. 1 andhas the pulley 21- with a consequent ratcheting motion of the plunger 17 and thesocketedthimble 14:, it being understood that the shade is capable of being lowered toany desired point and retained against further downward movement by the spring pressed plunger 17 engaging in the thimble sockets 16. During the lowering movement of the shade, the pull cord 23 being wound upon the pulley 21 and when it is desired toelevate the shade, it is only'necessary to pull upon the cord 23 to cause a reverse rotation of the roller bearing 8 against the ratchet devices in the bracket 6 so that the shade may be raised to the desired height. In the raising of the shade, the projecting ends 11 of the shade stick limit the upward movement of the shade by engaging the lower faces 2% of the brackets 6 and 7 as shown by dotted lines in Fig. 2. With this construction or" shade roller mount, it will be observed that the roller operates to the exclusion of springs for elevating the shade while the shade is capable of being retained in any adjusted position by the tensioned plunger devices disclosed and also, the raisingand lowering thereof is accomplished in an easy and quick manner.

While there is herein shown the preferred embodiment of the invention, it is neverthelesstobe understood that minor changes may be made in the form, combination and arrangement of parts without departing from the spirit and scope of the same as claimed.

What is claimed as new is l. A device of the class described comprising a pair of brackets, a shade roller supported at its opposite ends in said brackets, one or" said brackets having a metallic cylinder arranged transversely thereof, a metallic thiinble on the adjacent end of the shade roller journaled in said cylinder, sockets formed in said thimble and roller end, the bracket having a vertical socket therein, a spring pressed plunger within said socket adapted to be. consecutively seated in adjacent thimble sockets, the other end of the shade roller projecting beyond the other bracket, a pulley secured to the projecting end thereof, a spring finger carried by the last named bracket and overlying the pulley and a cord secured to said pulley for rotating said shade roller.

2. A device of the class described comprising a pair of brackets, a shade roller supported at its opposite ends in said brackets, one of said brackets having a metallic cylinder arranged transversely thereof, a metallic thimble on the adjacent end of the shade roller journaled in said cylinder, sockets formed in said thimble and roller end, the bracket having a vertical socket therein, a spring pressed, plunger within said socket adapted to be consecutively seated in adj acent, thimble sockets, the other end of the shade roller pro ecting beyond the other bracket, a pulley secured. to the projecting end thereof, a spring finger carried by the last named bracket and overlying the pulley, a cord secured to said pulley for rotating said shade roller, and a shade stick carried by the shade and extending from opposite sides thereof adapted for engagement with the shade roller brackets during the rising movement of the shade.

In testimony whereof I aifix my signature.

PIETRO BIASUCCI.
