SHADE-HOLDING DEVICE.

SPECIFICATION forming part of Letters Patent No. 765,878, dated July 26, 1904.

Application filed June 3,1899.

To all 1072/0721, it 712/601] concern:

Be it known that I, EDWARD T. BURROWES, a citizen of the United States, residing at and whose post-office address is Portland, in the county of Cumberland and State of Maine, have invented certain'new and useful Improvements in Shade-Holding Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improvement in spring-actuated holding devices for shades and curtains, and it is embodied in the construction and arrangement of parts hereinafter described, and defined in the claims.

The invention relates more particularly to that class of shade-holding devices wherein outwardly-pressed friction blocks or tips are employed, the same being carried by a stick attached to the lower end of the shade and bearing with sufficient friction against the window-jambs to retain the shade in any desired position of adjustment against the constant pull of the spring of the shade-roller.

The above type of holding devices is now well known and largely used. Such devices, however, have been so constructed that it is possible to force the friction-shoes out of the vertical grooves on the window jambs on which they are usually located, thereby causing considerable confusion and trouble. To obviate this objection, enlongated shoes have been used, so that when the curtain-stick is tilted the extended ends of the shoes will hug the bottoms of the grooves, and unless unusual pressure is exerted against the stick the shoes will not escape. Again, in the prior devices generally the tension of the roller-spring has been relied on for drawing the stick up into a horizontal position after being tilted.

The present invention is designed to overcome the objections existing in the devices heretofore made by providing means which can be located within the stick for forcing the stick into its horizontal position after tilting and, further, to provide a construction whereby the heads may be located in grooves and Serial No. 719,226. (No model),

overlapping retaining-flanges canbe successfully employed for-positively preventing the escapement of the heads from the grooves.

The present invention is well adapted for use in connection with open or summer cars, which require fixtures of special size and proportion to stand the rough usage to which they are subjected. Heretofore the confined elongated tip owing to the extended leverage has a tendency to damage the fixture and break off the retaining-flanges of the grooves when the. stick was improperly raised or lowered by grasping the same near the end. My invention is designed to overcome this defect by permitting the successful use of the retaining flange or strip.

A further object of the invention is to provide a special form of head and friction block or pad which will successfully prevent sticking of the head in the groove and allow the fixture to work smoothly irrespective of the point at which the curtain-stick is grasped or moved and, further, to provide a device of the character above indicated which can be easily adjusted to the stick and which will be strong in its various parts and connections. In the accompanying drawings I have shown a fixture embodying the nature and principle of the invention; but I desire it understood that the form therein delineated is employed for the purpose of illustration and that various changes can be made Without departing from the nature and principle of the invention.

In the drawings, Figure 1 is a side elevation of one end of a curtain-stick with its shoe and showing in section a part of a windowcasing and also showing in dotted lines the relative position between the shoe and the stick when the latter has been tilted. is a longitudinal central section through the construction shown is Fig. 1. Fig. 3 is an end elevation of the shoe. Fig. 4 is a plan view showing the cross-section of the adjacent portion of the window-jamb. Fig. 5 is a detail view of the spring-carrying rod, showing the parts in section; and Fig. 6 is a detail view of the holding device attached to a curtain and shown adjusted to a frame.

position,and owing to the length of the settinghead above and below the pivot of the extension the former will be forced back, compressing the spring L, which latter is of considerable strength. As the lifting pressure is released from the stick the tendency of the spring L will be to force the setting-block outward, and its force will be sufiiciently great to reset the shoe in its proper position at right angles to the stick, carrying the stick to its proper hori- Zontal position. As the stick is tilted the ends of the shoes are forced, respectively, into contact with the bottoms of the grooves and the retaining-plates. Should the pressure on the stick be great, the tendency would be to tear the plate off; but, owing to the construction and arrangement of the setting-head, with its spring, the shoes are permitted a tilting movement, thereby relieving the plates from the overpressure which would otherwise be exerted against them. By forming the setting-heads with the one straight side the same is prevented from engaging with the retaining-plates.

It is obvious that the fixture above described can be used in connection with the ordinary and now well-known pinch-handles simply by extending the rods back and applying the handles in the well-known manner. To adjust the shoes in or out to increase or diminish the spring-pressure, it is only necessary to screw the extensions in or out of the thimble on the rods, which latter are held from rotation by the pins Working in the grooves of the sleeves (Z.

It will be noticed that the setting-springs are inclosed within the tubular stick; that the extensions on the setting-heads are also projected into the ends of the stick. This is important, inasmuch as the extension-afl'ords a guide for the moving parts and the springs are wholly concealed. The abutting surface of the heads or shoes are shown slightly curved; but they may be straight, if desired.

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

1. In a shade-holding device, the combination with the window jamb having guidegrooves thereon, of a shade-stick, spring-actuated rods located within the stick, shoes pivotally connected to the rods, springs on the rods for retaining the shoes in a position at right angles to the stick and a retaining-flange on the jamb projecting over the grooves for preventing the escape of the shoes from the grooves, substantially as described.

2. In a shade-holding device, the combination with the window-jambs having vertical guides thereon, of a shade-stick, spring-actuated rods within the stick, shoes pivotally connected to the rods, setting-heads in the stick, means for yieldingly forcing the heads against the shoes and means for retaining the shoes in the grooves, substantially as described.

3. In a shade-holding device, the combination with the window-jambs having guides thereon, of a shade-stick, spring-actuated rods within the stick, heads pivotally secured to the rods and having antifriction-wheels on one side thereof, springs on the rods for retaining the head in proper position relative to the stick and retaining-flanges on the-jambs projecting over the wheels for retaining the shoes in proper position relative to the guides, substantially as described.

26. In a curtain-holding device, the combination of a tubular stick a short inner tube slidably arranged to enter within the end of the stick, a rod slidably arranged within the short inner tube, spring means adapted to move the inner tube outwardly, or toward the end of the stick, means within the stick for limiting the outward movement of the inner tube, a tilting head at the end of the stick, pivotal connection between the stick and the head, and a spring within the stick and surrounding the rod for holding the head normally at right angles to the stick; substantially as described.

27. In a curtain-holding device, the combination of a tubular stick, a head pivotally supported at the end of the stick, a short tube slidably arranged to extend within the end of the stick and having endwise movement therein, spring means within the stick for moving ner tube, a spiral spring within the stick engaging the inner tube and having movement therewith, for holding the head normally at right angles to the stick, and spring means carried by the stick tending to move the inner tube, head and spring outwardly or toward the end of the stick; substantially as described.
