ADJUSTABLE BEARING FOR CURTAIN-POLES.

SPECIFICATION forming part of Letters Patent No. 495,332, dated April 11, 1893.

Application led November 16 1892. Serial No. 452,160. (No model.)

.T0 all whom t may concern,.-

Be it known that I, JOHN HEIMKE, of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Adjustable Bearings for Shade- Rollers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in adjustable bearin gs for shade rollers, and consists in the novel arrangement and combination of parts as will be more fully hereinafter described and set forth in the claims.

The object of my invention is to construct an improved bracket bearing for the support of shade rollers and which is adapted to be adjusted to suit dierent lengths of shade rollers. Itis especially designed for houses which are built for rental and in which a number of dierent tenants often live, and

as there is such a variety in the length of` shade rollers, it is necessary either to provide horizontally adjustable brackets, or else change the brackets to conform with the rollers. The presumption is that a proprietor could place the brackets constructed after my invention, in the building when in the course of construction, and thus when a new tenant occupies the room, it would not be necessary for them either to alter the rollers or put up new brackets, asin nine cases out of ten the tenants rollers would be of a different length than the occasion required.

Another difficulty which is overcome by the use of my improved bracket, is the necessity of adjustment of the brackets, to allow for the perfect operation of the roller, as the improved bearing is especially designed for use in connection with the spring rollers which are now generally used.

In the drawings: Figure 1 is an elevation of' a window-casing with parts broken away, and showing my improved invention supporting an ordinary shade roller. Fig. 2 is a side elevation of my invention. Fig. 3 is an end elevation of same looking from the right hand at Fig. 2. Fig. 4 is a reversed end elevation of the device. Fig. 5 is a top plan view of the same. Fig. 6 is a longitudinal section taken on aline X--X in Fig. 5. Fig. 7 is a perspective View of my complete invention. Fig. 8 is an end elevation of the bracket providing a bearing which completes the necessary pair, for the successful operation of the shade roller.

Referring to the drawings: 1 indicates a window-casing having my adjustable curtain brackets 2 secured thereto by screws, and set brackets 2 being in horizontal alignment near the top of the casing in order to support the shade roller 3 which is mounted therein. The bracket bearing 2has all of its parts mounted upon a plate 4of elongated rectangular form and which has projecting at both ends lugs 5 .provided with apertures 6 through which screws are adapted to be inserted to screw the device to the frame 1. Projecting upwardly from said plate 4 is a plate 7 which is of the entire length of the device exclusive of the lugs 5 and which is of less width than the plate 4. rlhe sides 8 of the plate 7 are inwardly inclined toward each other to form alocking guide for a sliding shell 9, the same consisting of a plate having depending inwardly inclined sides l0, the entire construction being substantial-ly about one-half the length of the guide-plate 7. The inner faces of the projections 10 present an outline coinciding with the side faces 8 ot' the guide-plate 7 and it is necessary in order to join the two together to slide the plate'eQ over the guide 7 fromone end of same. VThe plate 4 is provided upon one side with projecting lugs 1l having pins 12 projecting upwardly at right angles therewith and upon the same side of the sliding shell 9 is a projection 13 which is located intermediate of the two ends of same and substantially of about one-half its length and said pins 12 are adapted to limit the reciprocatory movement of the shell 9.

In the construction of this device it is necessary to slide the shell 9 upon the guide 7 before placing the pins 12 in position. Proj ecting upwardly from the shell 9 and at right angles therewith at one end,is a standard or plate 14, the edge ofwhich is curvilinear in design and which has secured upon the outer face thereof, a plate 15 substantially oval in form and which is designed to strengthen the bearing portion of the plate 14, said projection 15 only occupying a small space near the upper and outer sides of said plate 14. Proj ecting downwardly into the plate 14 and pro- IOO ' as the widening of the slot is only upon the inner edge of same, an inwardly projecting portion 18 is left, the object of which is to prevent an undesired withdrawal of the projecting pin 19 in the end of the roller 3. The

shell 9 at a point adjacent the end from which the plate 14 extends, is provided with a screwthreaded opening 2O which extends downwardly through the top plate, and which is adapted to receive the threads upon an ordinary thu mb-screw 21, by means of which the sliding bearing can be normally securedv in any desired position upon the guide 7. The rectangular opening 17 is adapted for the reception, as before stated, of the pin 19 upon the'roller 3.

As is well known the pins upon spring rollers, are or more specifically one of the pins, the same being the one in connection with the spring mechanism, is provided with chamfered sides, the same admitting of the passing of the pin through the opening 16 and the projection 18 prevents the disengagement of said pin 19 from its position in the opening. y

The other member of the pair of bracket bearings is shown in Fig. 8, the same consisting of parts exactly similar to the construction above described, except that a circular aperture 22 is used in place of the rectangular opening 17. v

The application of the roller to the bearings is well known, and therefore needs no specific description.

The bearings as herein described are equally as well applicable to the old style of curtain rollers minus the spring attachment, as the circular pins in the ends of same can be placed in the openings 17 and will be successfully operative therein.

The adjust-ment of the bearing is very simple as in an ordinary sized'bracket, the stroke of adjustment is fully an inch and a half, the entire length of the device being about two inches. It will therefore be seen that with adjustable bearings for both ends of the roller, a dierence of three inches in the length of the roller can 'be accommodated, that is in case the length is of increase. The

entrance of the opening 16 is slightly flared outwardly in order to guide the admittance of the pin 19. To adjust the bearing it is necessary to unloosen the thumb screw 21 and slide the bearing along to the desired point where it will remain normally stationary upon the resetting of the thumb screw 21.

Having fully described my invention, what I claim is- 1. An improved shade roller bearing bracket having a base plate provided with a longitudinal dovetailed rib and with projecting lugs adjacent both ends and upon one side of said plate, pins projecting outwardly from said lugs, and a sliding bearing-plate carried by said base plate and provided with a dovetailed groove for receiving said rib, and with a lug projecting at one side and between said pins 5 substantially as set forth.

2. An im proved shade-roller bearing-bracket having a base plate of elongated rectangular form and provided with a longitudinal dovetailed rib, perforated lugs projectingfrom the ends of the plate, projectinglugs adjacent both ends and upon one side of said plate, pins projecting outwardly from said lugs at right angles thereto, and a sliding bearing plate having a dovetailed groove adapted to receive said rib, said bearing plate being provided with a lug projecting between said pins; substantially as set forth.

3. An improved shade roller bearing bracket having a base plate and guide, abearing plate with downwardly and inwardly inclined sides, the same adapted to be slid upon the guide from one end, lugs upon the side of the base plate, ay projecting lug substantially one-half the length of the bearing plate and `located intermediate of its length upon one side, pins projecting from said lug against which said lug upon the `bearing plate is adapted to strike in its reciprocatory movement to determine the length of same, and an upwardly proj ecting plate at right angles with said bearing plate at one end of same, said plate havinga projecting portion upon one of its sides and an opening through said plate and projecting portion to provide a bearing for the pin upon one end of the shade roller, substantially as set forth.

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