SHADE-ROLLER BRACKET.

Specification of Letters Patent.

Application filed January 24, 1911.

Patented May 23, 1911.

Serial No. 604,321.

To all whom it may concern:

Be it known that we, MARTIN RHEIN and GABRIEL J. RHEIN, citizens of the United States, residing at Baltimore, in the State of Maryland,have invented certain new and useful Improvements in Shade-Roller Brackets, of which the following is a specification.

This invention relates to improvements in adjustable brackets for supporting spring shade-rollers on window-frames.

In large cities the tenants of rented dwelling houses frequently make changes of occupancy-a tenant moves out and another tenant moves in; each tenant has his own window shades and these vary in width; the windows and window-frames of different houses vary in width and as a consequence of these conditions all sorts and sizes of shade-roller brackets are screwed and fastened to the .wood window-frames each succeeding tenant putting up his own brackets when he moves in and taking them down when he moves out, much to the defacement and permanent injury of the wood work of the window frames. To obviate these objections we have provided shade-roller brackets with improved means for adjustment-a double adjustment of the journal-end ears in the same direction across the base-plate being embodied in each bracket whereby to accommodate with great nicety of fit varying lengths of shade-rollers.

By applying to a window frame our improved brackets which are adapted for any length of shade roller, and to remain permanently on the frame, the owner of a house will prevent all defacement and injury to the wood work that has heretofore followed as a result of the repeated removal and replacing of brackets.

The improved shade-roller bracket is clearly illustrated in the accompanying drawing, in which,-

Figure 1 .is a front view of the upper part of a window-frame showing a pair of the improved shade-roller brackets in position, ready to receive a shade-roller. Fig. 2 is a front view, on a larger scale, of one of the brackets. Fig. 3 is a vertical cross-section of the bracket on the line 3-3 of Fig. 2. Fig. 4 is a top edge view of the bracket. Fig. 5 is a back view showing the side reverse from that seen in Fig. 2. Fig. 6 is an end view of one of the slidable roller bearings.

The base-plate, 1, is provided with two screw-holes, 2, for attachment to the window-frames and has two parallel horizontal cross-slots, 3. A loop, 4, is open to receive a slidable shank, 5, and allow it to move therein horizontally; this loop is provided at both its upper and lower edges with a rearward-turned hook or clip, 6; each hook or clip fits loosely in one of the said two cross-slots, 3, and at the rear side of the base-plate the ends of the two hooks project toward each other, as shown in Figs. 3 and 5. The construction of the base-plate, 1, with the two cross-slots, 3, and then providing the loop, 4, with two hooks which are loose in said cross-slots, enables the loop itself to be adjusted by being shifted or moved crosswise of the said plate, l, either to the right or to the left, as will be presently described.

Two brackets of the character described and two slidable shanks, 5, are Vemployed for supporting eacli'shade-roller. Each of the slidable Shanks, 5, has two ears, 7 provided with bearings or holes for the journal-ends of the shade roller. The ears of one shank have holes or bearings in the shape of a straight slot, 8, see Fig. 3, and the ears of the other shank have bearings in the form of a round hol-e, 9, see Fig. 6; these two forms of hole or bearing are required for the wellknown Hartshorn spring roller. The shank, 5, may be in the loop, 4, so as to locate the ear, 7, at the left-hand side of the loop, as shown in Fig. 2, or by reversing the shank in the loop the ear, 7 may be located at the right-hand side of the loop, as indicated by broken lines in Fig. 2. This reversal of p0- sition of the shank and ear affords a wide range of adjustment for rollers of different length. The metal of the ears, 7, immediately surrounding the slots, 8, and holes, 9,

is swaged or struck up concavo-convex, that is, on one side the face of the metal about or around these holes is depressed or made concave as at, 10, and on the opposite side the face of the metal is bulged or convexed, as at, 11. The two slots, 8, in the bracket of Fig. 3 are reversely bulged, that is, one face of th-e metal ears, 7, shows a slot in a concave, 10, and the other slot in a convex, 11; then of course the opposite face of the same ears shows the reverse. The bulging or convex side, 1l, is the one that should contact with the end of the roller, and by constructing the two ears as shown with a convex 11, on each of the two opposite faces of the ears, it is rendered immaterial whether the ears are positioned at the right-hand i side of the loop, 4, or at the left-hand side,

for in either position a convex, 11, will contact with the roller end. That has been stated rela-tive to the slots, 8, is also true with respect to the holes, 9.

The movable loop, 4, has a set-screw, l2, which enters the loop so that the end of the set-screw will impinge and bear on the slidable shank, 5, and hold it from movement. This set-screw also prevents the loop, 4, from moving by the effect of drawing the two hooks or clips, 6, in tight frictional contact with the rear side of the base-plate, 1.

In order that the hooks or clips, 6, on the rear of the baseplate may have space that will permit them to move, the base plate, l, rests on two blocks or feet, 13, that raise the plate and form a space; one of these blocks at each end of the plate and screws, 14, shown in Fig. 3, keep the parts in position. Two brackets are secured by screws to a window frame as seen in Fig. l and in the operation of adjusting the brackets to receive any particular shaderoller the two shanks, 5, should be set in their respective loops in approximate positions to fit the length ofthe particular shade-roller; and then the journal ends of the shade-roller should be inserted in the slot, 8, of one bracket and round hole, 9, of the other bracket, being careful to observe that the convex face, 11, on the bracket is next to the end of the roller. When the roller has thus been preliminarily placed in position and is loosely held by the two brackets,either one or both of the loops, 4, may be shifted enough to cause the d-esired tightness of it, and when the proper t has-been thus obtained the two set-screws, 12, should be tightened, and it will then be impossible for the roller to accidentally drop from the brackets.

Having thus described our invention what we claim and desire to secure by Letters Patent is,-

1. A shade-roller support having in combination a base-plate; an open loop attached movably to the base-plate and adjustable thereon in a crosswise direction; a shank which fits in said loop and is adjustable therein by sliding in a direction crosswise of the base plate and said shank provided at one end with ears having bearing holes for the journal ends of shade-rollers, whereby the bracket embodies double means for the hold said shank from moving and also holds the loop itself from moving.

In testimony whereof we afiX our s1gnatures 1n presence of two witnesses.
