SHADE-ROLLER.

Specification of Letters Patent.

Application filed April 30, 1913. Serial No. 764,497.

To all whom it may concern Be it known that I, ANDREW MCLEAN, citizen of the United States, and resident of Passaic, county of Iassaic, and State of New Jersey, have invented an Improvement in Shade-Rollers, of which the following is a specification.

The object of my invention is to provide a construction of shade roller in which the pintle shall be longitudinally adjustable, so as to give capacity for adjustment between the end supports, whereby the total length of the distance between said supports for the spring shaft extension at one end and the pintle at the other end may vary and the said shaft extension and pintle of the roller automatically adapt themselves to the distance between the supports at all times. In this manner, the shade roller may be easily installed, as no nice positioning of the bearings apart is required, since any variation in the distance will be compensated for by the employment of a longitudinally adjustable pintle bearing at one end of the roller, the extent of adjustment of which is greater lthan any allowable irregularity in spacing the supports.

My improvements also provide capacity for installing the shade roller in the supports or bearings, by rst inserting the journal of the spring actuated pintle in its support or bracket, and then inserting the fiattened end of the spring shaft into the polygonal hole in its bracket or support, whereby the roller may be arranged close up to the head of the window frame, because no head room is required for adjustment, as is necessary with shade rollers in common use.

My invention consists of a shade roller having a pintle at one end adjustable longitudinally in metallic bearings and having a collar which limits its movement, and a spring surrounding the pintle body and contained within the. roller, one end of the spring bearing against the collar and the other end supported by the inner metallic bearing for the pintle body, whereby the pintle is guided in durable bearings and nor-V mally spring pressed outward, all of which is more fully described hereinafter and more particularly defined in the claims.

My invention will be better understood by reference to the drawings, in which:

Figure 1 is an elevation of a shade roller embodying my improvements, each end of the roller structure being in section for more clearly disclosing the nature of the invention; Fig. 2 is a cross section of the same on line w-; and Fig. 3 is a sectional elevation of the pintle end'of a shade roller having a metal arrel an'dalso embodying my improvenients.

2 is the wooden roller and lmay have the' usual spring shaft 3 and ratchet collar 3a, pawls 8", and spring 4 at one end to make it self-winding, the shaft 3 having the polygonal end 5 fitting a corresponding hole in the supporting bracket 6. In this case, however, the polygonal aperture in the bracket need not be open at the top, as heretofore has been customary. The other end of the roller is bored axially to a considerable depth to pro vide a hole of two diameters, the outer boring 7 having the larger diameter and the inner boring 8 the smaller diameter, the total length of the hole being somewhat greater than the pintle which works in it.

10 isa metallic washer or annular disk which is forced down in the hole portion 7 of larger diameter and seats upon the wooden shoulder 9 between the two -parts 7 and 8 of the hole, the hole in this disk being somewhat less in diameter than the hole 8. Fitting over the end of the roller is the end cap 17 which has at its center an aperture constituting a bearing or guide 18 for the pintle. The pintle consists of a straight piece of rod turned down to different `diameters to provide the operative parts as follows: The body part 13 is extended at 11 through the bearing or guide 18 and provided with a col lar 14 which is of less diameter than the diameter of the hole 7 but which is coniined therein and acts as a stop by coming in contact with the end cap to limit the outward movement of the pintle; the extreme outer end of the part 1l of the body is provided with the journal 12 of smaller diameter, which is received in the bearing 19a in the bracket or support 19; and the eXtreme inner end of the body part 13 is provided with an extension 15 of smaller diameter which is guided through the hole of the washer or annular disk, whereby it is guided in a metal bearing and kept clear of the rough bored hole 8 in the wood. This pintle, furthermore, provides a shoulder 2O between the parts 13 and 15, which may act as a limit stop by coming in Contact with the disk 10 and thereby prevent the inward thrust of the pintle Vcausing its end 12 to pass through the guide bearing 18; but on the other hand,

it insures that the journal end 12 shall always remain extended beyond the guide 18.

Surrounding the body of the pintle is a coilspring 16, one end of which rests against the metallic disk 10 and the other end against the collar 14 of the pintle, with result of forcing the pintle outward with a yielding pressure and allowing it to adapt itself to the bearing in the bracket-19. In this manner the brackets 6 and 19 may be attached to the window frame in approximately the relative positions desired and the adjustability of the pintle will compensate for any inaccuracy in the positioning or distance apart intended or desired. The spring 16 is of a diameter which loosely lits the body part 13 and so as to be held clear of the rough sides of the hole 7 in the wood in which it is housed.

By the employment of my improvements, no skill is required in installing the shade roller and its supports, and no danger will arise by reason of the roller falling owing to the supports being slightly too far apart, as frequently happens with the ordinary constructions of rollers having fixed pintles. No head room is required for inserting the roller in its supports and the adjustment upon the brackets is more easily made than in the rollers having fixed pintles.

In the construction shown in Fig. 3, the roller 2b is of tin `in tubular form and is fitted with a wooden plug 2a having the construction shown in Fig. 1 in respect to the adjustable pintle.

While a self-winding means is desirable for the roller and is commonly employed with my improvement, I do not restrict myself to such use as my adjustable pintle may be employed in the end of any type of roller which is to be supported at each end.

I have shown my invention in its preferred form, but the minor details may be modified without departing 'from the spirit of the invention.

^ Having now described my invention, what I claim as new and desire to secure by Letters Patent, is l 1. In a shade roller, the combination of the roller having a wooden end bored inward with two diameters, the larger being ar' ranged at the outer end, an annular metallic disk set into the bottom of the larger hole of the roller and providing an axial bearing in alinement with the smaller hole, an outer metallic bearing axially arranged with the roller and holes therein and attached to the end thereof, a pintle consisting of a body extending through the outer earing and having an inwardly directed guiding extension working through the hole of the annular disk, and said pintle further having a collar about the body portion to limit the outward movement of the pintle by coming in contact with the outer bearing and also having a journal at the extreme o uter end of the body, and a coil spring surrounding the body of the pintle and having one end pressing against the collar thereof and the other end pressing against the annular disk, whereby the pintle is normally held in an outward position of adjustment but is at all times free to be forced inward in its metallic bearings in adapting the roller to the sup` ports or to compensate for varying distances between the supports.

2. In a shade roller, the combination of the roller havin a wooden end bored inward with two iameters, the larger being arranged at the outer end, an annular metallic disk set into the bottom of the larger hole of the roller and providing an axial bearing in alinement with the smaller hole, an outer metallic bearing axially arranged with the roller and holes therein and at` tached to the end thereof, a pintle consisting of a body extending through the outer bearing and having an inwardly directed collar about the body portion to limit the outward movement of the pintle by coming in contact with the outerbearing and also having a journal at the extreme outer end of the body, and a coil spring vsurrounding the body of the pintle and having one end pressing against the collar thereof and the other end pressing against the annular disk, whereby the pintle is normally held in an outward position of adjustment but is at all times free to be forced inward in its `metallic bearings in adapting the roller to the supports or to compensate for varying distances between the supports.

3. In a shade roller, the combination of the roller body having at one end a shaft having a polygonal end and a winding spring between the shaft and the roller body, a support for the polygonal end of the said shaft, a support having a journal bearing for the other end of the roller, and means at said other end of the' roller for connecting it with the journal bearing of the last mentioned support, consisting of a longitudinally adjustable pintle having a collar intermediate of its ends and a journal at the #xtreme end, metallic guides for the pintle secured to the roller at opposite sides of the collar of the pintle, and acoil spring sur` rounding the pintle and having one end pressing against the collar and the other end pressing upon the inner of the metallic guides.

4. A shade roller, having an end portion bored with a hole of two diameters, the larger extending to the end of the roller,

the pintle and having one end 'pressing 10 against the collar thereof and the other end pressing against the inner metallic guide.

In testimony of which invention, I hereunto set my hand.
