Specification of Letters Patent.

Application iled April 20, 19111. Serial No. 833,023.

T0 all whom t may concern:

Be it known that 1, JOHN M. GAMBON, a citizen of the United States, and a resident of the city of St. Louis and State of Mlssouri, have invented a new and useful lmprovement in Window-Shade Fixtures, of which the following is a specification.

My invention relates to window shade luixtures and particularly to that type which holds the shade in position at any height to which it is raised.

Among the principal objects of my 1nvention is to provide a simple and inexpensive window shade fixture which will keep the shade from sagging in or out at any point to which it is raised and which will guide the shade so that it will wind andv unwind evenly. i l Further objects are to Aattain certain other advantages, as will more fullyI appear hereinafter.

The invention consists in the parts and in the-arrangements and combinations of parts as will be set forth more lfully hereinafter.

ln the accompanying drawings, which form part of this speciication, and in which like reference characters refer to like parts throughout the several views, Figure 1 1s a front elevation of a shade fixture embodying my invention showingrv it applied to a car window; Fig. 2 is an end elevation of the shade xture shown in 1, the window and parts of its casing being shown in section; Fig. 3 is an enlarged front elevation of the roller of the shade fixture shown in Fig. 1; Fig. t is a detail section of the tension pulley and its associate parts taken on the line 4.-4 on Fig. 6; Fig. 5 is a section on the line 5-5 on Fig. 6; Fig. 6 is a section on the line 6-6 on Fig. 5; and Fig. 7 is a detail diametric section through one end of the Shade roller. i K ,Y While for the purpose of illustration l have shown my improved shade xture applied to a shade especially adapted for carV windows, it is to be understood that my invention is not limited to this use but may be used on any other type of window or door.

In the construction which l have shown,

a shade 1 is fastened at one end to a roller 2 and is wound upon this roller lin the `ordi- -nary way. Fitted over each end of the roller 1 is a hollow Adrum 3 which is fastened thereto by nails or screws L1. The outer circumferential surface ofthe drum 3 is conical with the diameter of its outer end corresponding to the diameter of the roller 2 together with the shade 1 fully wound thereon,

rammen npr. e, reis.' A

and the diameter of its inner end correspondi ing to the diameter of the roller 2 together with the shade when it is fully unwound from the roller. In the conical outer surface of the drum 3 is a `helicahgroove 5, which has the same'number of turns between the Iouter'and inner ends of the drum as there fastened to the outer end of the drum 3 in any suitable manner and is engaged in the groove 5. The drum 3 is provided with an integral pin 7 in the center of its outer face. Thepins 7 are mounted in vertical slots 8 in the brackets 9 which are fastened by screws or nails l0 to the inside faces ofthe sides 11 of the window casing.

To the lower or free end of the-shade 1 is fastened a rod 12, the ends of which extend beyond the sides of the shade into grooves 13 in the inside faces of the sides 11. rlhe grooves 13 extend from the top to the bottom of thesides 11. .Each end of the rod 12 has a slit 14 therein extending a short distance is a bracket 16 which is fastened by screws `or nails 17 to the inside face of the side 11 and'which has 'two arms 18 and 19 vextending at right angles to the side 11. rlhrough the arm 18 passes a screw-threaded rod 20 which has at one end'a knurled head 21 and a knurled lock nut 22 and which is fastened at 5 the other end to one end of a tension spring 23. The other end of the spring 23 is hooked over a hook 24 secured in a stirrup 25. Jour- `naled in the stirrup 25 is a grooved pulley 26 about which the cord 6 passes. ln the arm 19 are two holes 27 for the cord 6 to pass through. The arm 19 is on a level' with the top face of a hinged board 28 which, vin this instance, forms the window sill. The hinged board 26 has anotch 29 cut along each edge to permit its ends to pass by the arms 19 of the brackets 16.

In the operation of 'my improved shade fixture, asthe shade 1 is lowered by pulling upon the rodv 12 in the usual manner, and as the shade 1 unrolls from the roller 2, the

6 which may result from stretching. The

tension of these springs 23 can be adjusted by turning the lock nut 22 and the head 21. In case a strong side pressure is placed upon the shade 1 suflicient to overcome the tension of the springs 23, the pulleys 26 will hit the under sides of the arms 19 and prevent the shade from sagging beyond a certain point. The friction of the parts holds the shade 1 in any position that it is put. Theshade 1 will wind or Vunwind evenly from the roller 2, and one end of the rod 12 cannot be raised higher than the other end so as to bind it, because each end of the rod 12 is connected to 'one end of the roller 2, and as one end of the rod 12 is moved it turns both ends of the roller 2 the-same amount and consequently moves the opposite end of the rod 12 also the same amount.

It is apparent that various changes can be made in the particular construction which I have shown and described without departing from the spirit of my invention, and I do not wish, therefore, to be limited to this exact construction.

What I claim is:

1. In a shade fixture, a shade roller, a shade adapted to wind on said roller, a conical drum secured te each end of said roller, and having a helical groove in its circumferential face, a rod secured to the free end of said shade, pulleys connected by springs to the Window casing near the bottom thereof, and a cord secured at one end to each drum and adapted to wind in said groove toward the smaller end of said drum, each cord passing around one of said pulleys and connected at its other end to the corresponding end of said rod, said springs operating to hold said cords taut.

2. In a shade fixture, a shade roller, a shade adapted to wind on said roller, said roller having a conical drum at each end thereof, each drum having a helical groove in its circumferential face, a rod secured to the free end of said shade and having its ends fitting into grooves in the sides of the window casing, a cord operatively connected at one end to each drum, to wind or unwind as said shade is unwound or wound respectively, said cords in Winding on said drums moving toward the smaller ends of said drums, and a pulley over which each cord passes, the other end of each cord being connected to the corresponding end of said rod.

3. In a shade fixture, a shade roller, a shade adapted to wind on said roller, said roller having a conical drum near each end thereof, each drum having a helical groove in its circumferential face, a rod secured to the free end of said shade, a pulley connected by a tension spring to the window casing near the bottom of each side thereof, a cord operatively connected at one end to each drum and arranged to wind on or unwind from said drum as said shade is unwound or wound respectively, said cords in winding on said drums moving toward the smaller ends of said drums, each cord being connected at its other end to the corresponding end of said rod, and means for limiting the upward movement of each pulley.

4. In a shade fixture, a Shade roller, a shade adapted to wind on said roller, a conical grooved drum fastened to each end of said roller, a cord secured at one end to each drum and connected at its other end to the corresponding side of the free end of said shade, said cords winding on or unwinding .from said drums as said shade un- Winds or winds respectively, said cords in winding on said drums moving toward the smaller ends of said drums, and means for guiding each cord between its ends.

Signed at St. Louis, Missouri, this 18th day of April, 1914.
