Application vlzlet'il'oveifiiber 1G, 1915. serialNo. 615529.

To all whom 'it 'may concern:

Be it known lthat I, ALBERT W. PAUL, a

citizen of the United States, residing at Chicago Junction, in the county Aof Huron `and State 4of Ohio, have 'invented certain new and useful Improvements in Shade-Rollers, of which the following isa specification. My present invent-ion 'relates to @a new and improved shade roller; and the primary object thereof is to provide 1a device of this character that affords facilities for fini-ng the upper end fof the shade thereto and provides for the accommodation of shades of various widths.

Another object of this invention is to provide an improved shade roller that nmay fbe constructed entirely of nietal yparts which will of course insu-re its longevity yet vl'not materially add to its weight Jor `the cost of manufacturing. y

A further Objectis to provide a shade roller which includes means for preventing binding of the coil actuating spring thlus providing `for Lfthe rcomplete operati'ven'ess lof the device at all times and guarding against breakage of the spring.

A still further object 'of the `invention is to provide Aa device of `the type fin fq-uestion that is extremely 'simple in construction and which, it is believed may he manufactured at a minimum cost. l

Various other objects and Vadvantages will become apparent during rthe 'conti-nuance of the following description.

The above and 'other 'objects 'which will become apparent, are accomplished by such means as are shown in their preferred form in the accompanying drawings, described in the following specification and then more specifically pointed out in the appended claim.

ln the accompanying drawings wherein. like characters designate like parts throughout the several views;

Figure l is a view in side elevation showing my invention in its preferred embodiment; the shade being shown broken away.

Fig. 2 is a View in longitudinal section.

`Fig. 3 is a fragmentary view showing in detail certain means for retaining the shade in place.

Fig. i is a view in section taken on line m4-of Fig. 3.

Fig. 5 is A1a view in 'section taken on line 5-5 'of Fig. 2.

Fig. 6 is a View in section taken on line l6--6 of Fig. 2. i I F ig. y7 is a perspective view of a detail. Fig. 8 is la simi-lar view. p Fig. 9 is a fragmentary view of afdelitional means y ln the drawings the numeral 10 designates the body portion of my improved shade roller which, in the present embodiment, is shown in the form 'of a tubular member `constructed of sheet metal. At one end the body 9 10 is for-med 4into an annular 4offset portion 11. -In practice a cap l5 is arranged at 'one end olf the body 10 v'and lhas an inturned flange 16 for engagement with `the fofl'set portion Ill. A disk i7 Sis carried within the cap l5 and is #provi-ded with a'centrall opening y18 and 1a pai-r preferably diametrically opposite Lpawl seats 19. Ehen 'the pawlseats assume 'this position `a pair :of paw-ls 20 lmay be @mounted therein :as :shown 'in ABeyond lthe disk 17a ibearing 2:1 islmount `ed in the cap l5 while fthe outer marginal edgejof the Ylatter is fben't inwardly as aft"22 to hold the parts 'in their `relative positions.

The body .10 is slotted intermediate its `ends as at '23 yso las to receive tongues 2i on the bearing '215. fllhe tongues 24 'are preferably bent into the :posi-tion shown 'in Fig. '2 'so .that their outer edges he flush with-the v.periphery fof `the body. order Ito engage a coil spring, such as will presently be described, the bearing 2a farther pron `yided with a pair of substantially parallel tongues 26.

A shaft 27 is now provided, one end there of projecting through the coincident opening in the disk 17 and being flattened as at 28 for engagement with a. suitable bracket (not shown) on the window frame. The other end of the shaft is loose with respect to the bearing 25 yet may be supported in connection therewith as will be presently pointed out. A coil spring 29 has one end fined to the shaft 27 as at 3() while its other end 3l has connection with the bearing 25, Ln View of the fact that the tongues 26 bear against the adjacent portion of the coil spring, tightening of the latter upon the shaft 27 is prevented and at the same time a bearing for the shaft 27 is provided. It

-for securing the shade in place.v

ics

has been found that by adapting this structure in preference to journaling the inner end of the shaft 27 in the bearing 25, not only saves much time and labor in the manufacture of the device but also serves, etliciently, the function performed.

rI`he shaft 27 is further provided with a ratchet 32 which is engaged by the pawls 20 as shown in Figs. 2 and 6. As the pawls 20 are slidable within their respective seats it will be understood that one of the pawls will always move by gravity into engage ment with the ratchet irrespective of the position of the roller when the latter is rotated and stopped gradually.

In order to attach the end of the shade 33 thereto the body 10 is provided with a plurality of stamped ears 3st which engage the said shade in the manner clearly shown in Figs. l, 3 and-4. While this form of securing means has proven very advantageous I find it advisable to employ a second roller 35 that is split longitudinally as at 36 so as to be positioned about the body 10 and the shade 33 in the manner shown in Fig. 1. rIhis second .roller constitutes an auxiliary clamp for substituting the clamps Vor ears 34C at one end of the shade roller, and when this second roller or clamping sleeve is employed, the unused clamping ears may be pressed into the respective apertures from which they were Struck up, thus av0iding obstruction to the clamping sleeve 35. After the second roller has been positioned Y into place all liability of the shade becoming disengaged from the body l0 is eliminated.

At its outer end the second roller 35 carries a cap 37,' which, in turn carries a trunnion 38. The trunnion 38, in the use of my device is received within a suitable bracket (not shown) on the window frame. Thus itwill be understood that by drawing the roller 35 outwardly the length of the device will be extended so as to accommodate shades" of diierent widths or be used in connection with window frames whereon Y the brackets are spaced a greater distance apart.

From the foregoing it is believed that the advantages and novel features of my invention will be readily understood and, therefore, further detailed description is deemed unnecessary.

In reducing my invention to practice I End that the forni referred to herein as the most practical and preferred embodiment is the most efficient, but realizing that certain conditions will necessarily v ry in concurrence with the adoption of my device, I desire to emphasize the fact that various minor changes in the details of construction and in the proportion of parts may be resorted to when required without sacrificing any of the advantages of my invention as defined in the appended claim.

Having thus fully described my invention,

what I claim as new and desire to secure by i Letters Patent is :V

In a shade roller, a tubular body having tongues extending inwardly, a member iiX- edly seated in said body by its engagement with the tongues of said body, said 'member hav'nig parallel elements extending toward one end of said body, a helical spring having one end fixedly engaged with said member and coiled around said parallel elements, and a shaft extending through said spring and through said end of the tubular body and having the other end of said spring secured thereto, whereby'one end of said shaft is held against said member between said parallel eiements, and whereby said cylindrical body may be rotated with relation to said shaft. f-

In testimony whereof I aiiiX-my signature in presence of two witnesses.
