VERTlCALLY-ADJUSTABLE SHADE-HANG ER.

SPECIFICATION forming part of Letters Patent No. 684,009, dated October 8, 1901.

Application filed March 16, 1901. Serial No. 51,516. (No model.)

T 0 ctZZ whom, it may concern:

Be itknown that LWILLIAM A. TEW, a citizen of the United States, residing at Bowling Green, in the county of Wood and State of Ohio, have invented certain new and useful Improvements in Vertically-Adjustable Shade-Hangers; and I do declare the following to be a full, clear. and exact description of the inve ntion,such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in vertical] y-adj u stable shadehangers designed especially to raise and lower the shade for the purpose of ventilation; and it consists of slotted socket-plates designed to be secured to the window-frame adjacent to the sash of the window and provided with a shade-carrying hanger secured to a ratchet -plate longitudinally movable within the socket-plates, and a springactuated pawl adapted to hold the shade-carrying plates at different heights, means being provided to raise the shade-hanger, and the latter designed to fall by gravity when the pawl is disengaged from the ratchet-teeth in the edge of the longitudinally-movable plate.

Another feature of the present invention resides in the provision, in combination with the socket member and the longitudinallymovable hangercarrying plate, of an adjusting-screw whereby the socket member and hanger-carrying plate may be held in frictional contact with each other for the purpose of partially breaking the force of the hanger. in cases where the shaderoller is heavier than usual.

My invention will be hereinafter more fully described and then specifically defined in the appended claims and is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which drawing.

Figure l is a perspective View showing my improved adjustable shade-hanger as applied to the frame of a window. Fig. 2 is a vertical sectional View through the socket member and the ratchet-plate. Fig. 3 is a rear elevation, and Fig. 4. is a detail view, of the socket-member blank before being bent to form a socket to receive the hanger-plate. Fig. 5 is a detail view showing the bracketarm and lug brazed thereto.

Reference now being had to the details of the drawings byletter, A designates a socketplate, made of any suitable material and of a single blank which is longitudinally slotted, as at A, said slot terminating a short distance from the ends of said member and the ends of the slots serving as stops to limit the' upper and lower throw of the hanger. This .socket member is bracket-shaped in cross-section, and in its flanged longitudinal edges screws may be passed through the metal, whereby the device may be attached to the frame of a window. The upper end of said member A is slitted, as at a, a short distance in from one end of the member, and intermediate the inner two arms formed by said slitting is a recess B. The inner edges of the arms 0 C on either side of said recess form the side walls of the recess and are apertured, as at O, to receive the pin D, on which the pulley Eis journaled. The upper ends of the arms 0 are preferably bent inward and in close contact, forming a shield over said pulley. The arms F F, which are integral with the member A, are apertnred to receive screws G.

The bracketarm H for supporting the shade-roller has a lug H secured thereto by brazing or otherwise, which passes through the longitudinal slot in the socket member,

and after passing through an aperture in the J pole-supporting-bracket T is securely fastened tothe sliding or longitudinally-movable plate K, which is located within the socket member. This plate K has notches K along one of its edges at intervals apart, said notches being adapted to be engaged by the nose of the pawl L, which is pivoted on a pin M, carried in a lug on the socket member. The nose of this pawl passes through an aperture in the wall of the socket member and is disposed in the path of the notches in the edge of the longitudinally-movable plate K to hold the latter at different heights. A spring N is mounted on said pin M and has one end scoured-to the pawl, while its other end rests against the socket member, said spring serving to normally hold the pawl in the path of said notches. A string R has one end secured to the pawl L near its edge and extending downward to convenient reach of the operator, who by pulling down on the string releases the pawl from the engaging notch in the longitudinally-movable plate within the socket member and allows said plate, with the shade-roller and also the curtain-pole bracket T, to drop. The string is passed up through the socket member over the pulley at the top, and its other end is fastened to the pole-supporting bracket T, and by pulling down on the portion of the string which passes through the socket member the bracket-carrying plate may be raised to its highest position.

In order to break the force of the dropping shade-roller, I provide a screw S,which passes loosely through an aperture in the downwardly-projecting end of the bracket-arm, which projecting portion is sprung outwardly from the socket member. This screw then engages in a threaded aperture in the plate K, and by turning the screw toward the socket member the lower end of the bracket is drawn toward the plate K and the two caused to bear frictionally against the opposite faces of the socket member, thus serving to make the dropping of the shaderoller and its attachments gradual.

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

1. A vertically-adjustable shade-hanger consisting in combination with the socket member and pawl and plate engaged thereby, a bracket-arm and lug carried by the latter, and passing through a slot in said socket member and secured to said plate, a screw passing loosely through the lower end of said bracket-arm, and engaging in a threaded aperture in said plate, and means for raising the bracket-arm, as set forth.

2. A bracket-retaining socket member,consisting of a plate of metal having its ends slitted forming arms, a recess intervening between the inner of said arms, the latter designed to form supports for a pulley-carrying pin, when bent at right angles to the flanges of said socket plate, combined with the bracketarm and plate secured thereto, a lug secured to said bracket-arm and working in an elongated slot in said socket-plate, as set forth.

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