SHADE-FIXTU RE.

SPECIFICATION forming part of Letters Patent No. 623,535, dated Apnil 25, 1899.

Application filed January 17, 1899- b'eliflil NO- (N 11105613 To all whont it 'nuty concern:

Be it known that I, WILLIAM H. GARLAND, of Kansas City, Jackson count-y, Missouri, have invented certain new and useful Improvements in Shade-Fixtures, of which the following is a specification.

My invention relates to shade-fixtures, and has reference particularly to an improvement in that class of devices used for arresting the rotation of the roller at any desired point, the object in this connection being to produce a device which is more positive and reliable in action than those commonly used, and which also embodies with an ornamental appearance simplicity, strength, and cheapness of construction.

To this end the invention consists in (-.er-'

tain novel and peculiar features of construction and combinations of parts, as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawin gs,i n which Figure 1 represents a face view of a shadefixture embodying my invention. Fig. 2 is an end view of the same. Fig. 3 is avertical section taken on the line III III of Fig. 2. Fig. 4 is a top plan View of the fixture as it appears in Fig. 2. Fig. 5 is a perspective View of the same with the parts detached.

In the said drawings, 1 designates the shaderoller shaft, and 2 the spool for the actuatingtape, (not shown,) whereby the spool is rotated in one direction or the other and the shade (not shown) wound or unwound, or in lieu of this construction a shade-roller of the spring variety may be employed.

3 designates a boss projecting axially outwardly from the spool, or if a roller were employed said boss would project radially from the same. This boss is provided with a crossbar 4 at its outer end extending diametrically of and projecting beyond the sides of the boss, said projecting ends being braced by means of the integral ribs 5, connecting them with the spool. At its ends said cross-bar 4 is provided with the outwardly-projecting stop-flanges 6 and at its center with a recess 7 and with a central journal-opening 8, which extends axially of and nearly to the center of the spool. (See Figs. 3 and 4.)

9 designates a spindle of the roller, said spindle fitting snuglyin the journal-opening 8 and provided at its outer end witlra flattened or rectangular portion 10. It is also provided with a collar or enlargement 1 1, provided at its inner end with a flange 12, which fits in recess 7, so that its outer face shalllie about in the same plane with the face of the cross-bar4. At diametrically opposite points, by preference, the collar 11 is provided with longitudinal notches, one wall of each notch being abrupt, as shown at 13, and the other wall beveled, as shown at 14.

15 designates a bracket provided with a central opening 16 sufficiently large to admit of the free revolution therein of the collar 11, but not sufficiently large to permit the flange 12 of said collar to pass through. This bracket is stamped to form the outwardly-projecting U-shaped guides 17, which extend radially of opening 16, and the bracket as a whole is just short enough to fit snugly between the stop-flanges 6 of cross-bar 4, but exceeds the latter slightly in width and is provided with the parallel inwardly-projecting flanges 18,v which are adapted to bear against the side edges of said cross-bar, and in order to secure said brackets upon the cross-bar the flanges 8' are cut away at the points 18 in order that the end portions of said flan gesthat is, those portions outward of the recesses 18may be bent inward, as at 19, against the inner face of the cross-bar 4, outward of the boss 3, as shown in Fig. 5. Before, however, these flanges are bent around said cross-bar, as described, the cylindrical sliding dogs 20 are fitted in the U-shaped guides 17, and when the parts are properly assembled said dogs may slide outward until arrested by the stopflanges or inward until such movement is limited by engagement with the collar 11.

The parts being properly assembled and the flanges 19 bent around the cross-bar 4, as described, the roller may be mounted in supporting-brackets (not shown) in the customary manner,- and the shade will be raised or lowered by manipulation in this case of the tapes (not shown) or by the usual method if the shade be of the spring variety.

In operation the roller will turn freely in the direction indicated by the arrow, Fig. 2, because the dogs slide freely up the inclined wall 14 of the topmost notch of collar 11, and when such movement is terminated the uppermost dog 20 by gravity will engage the corresponding collar-notch, and thereby prevent movement in the opposite direction to that indicated.

Vhen it is desired to wind the shade in the direction opposite to that indicated by the arrow, the operator first rotates the roller in the direction indicated, so as force the topmost dog outward until it bears against the periphery of the collar, and then rotates it or permits it to be rotated, accordingly as it is of the drop or spring type, rapidly in the opposite direction, in order that by centrifugal force the dogs,as they successively assume positions above the collar, shall remain at the outer ends of the guides 17, and thus clear the'abrupt wall 13 of the uppermost notch. As the shade is adjusted to the desired extent the movement of the roller is retarded by the operator in the customary manner, and immediately thereafter, the centrifugal force being removed, the dog 20 which happens to be ascending will slide downward, and automatically engaging the topmost notch of the collar will arrest further movement of the roller, as will be readily understood.

I am aware that shade-fixtures have been patented provided with spindles having a notched collar and radially-sliding dogs for engagement with said notches; but I am not aware of the existence of a device embodying the structural features of this invention.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a shade-fixture, a spindle, provided with a notched collar flanged outwardly at its inner end, a shade-roller rod, a sleeve secured thereto and provided with a boss having a cross-bar at its outer end and journaled upon said spindle, and provided with flanges projecting outwardly from the face of the cross-bar, and with a recess in the face of the cross-bar which receives the flange of said collar, a bracket fitting against the face of the non-recessed portion of the cross-bar and provided with a central opening which embraces snugly the collar of the spindle, with radial guides which register with said opening, 1

and with side flanges fittingsnugly against the side edges of the cross-bar and secured there to, and sliding dogs fitting loosely in said guides and adapted at times to engage the topmostnotch of the collar, and limited as to outward movement by the flanges fitting against the outer ends of the bracket, substantially as described.

2. In a shade-fixture, a shade-roller rod, a sleeve mounted thereon, a cross-arm at the outer end of said sleeve, provided with a recess in its face and a flange projecting outwardl y from each end,a spindle fitting loosely in said sleeve at the center of said cross-bar, and provided with a notched flanged collar, a perforated bracket to fit against the face of said cross-bar between said end flanges, and

against the outer face of the collar-flange of' the spindle to hold the atter reliably in position; the perforation of said bracket snugly embracing the notched collar of the spindle, sliding dogs fitting in said bracket-guides and adapted to reciprocate between the spindle and the cross-bar flanges, and flanges project ing from the bracket and embracing the side edges and inner face of the cross-bar, substantially as described.

3. In a shade-fiXture, a shade-roller rod, a sleeve mounted thereon and provided at one end with a cross-bar having a recessed face and a journal opening centrally of said recess, a non-rotatable spindle engaging said opening and provided with a notched collar having a flange fitting in said recess, a bracket formed with a central opening to snugly embrace the said collar, with radial guides, and with flanges adapted to be clamped around and upon said cross-bar to secure the spindle and the bracket in position, and sliding dogs arranged to reciprocate in said guides and engage said notched collar, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.

\VILLIAM II. GARLAND.
