RUDOLPH A. BREITENFELD, OF MADISON, WISCONSIN.

SHADE AND CURTAIN ADJUSTING DEVICE.

Specification of Letters Patent.

Patented Sept. 3, 1907.

Application filed April 9,1907. Serial No. 367,231.

To all whom it may concern.-

Be it known that I, RUDOLPH A. BREITENFELI), a citizen of the United States, residing at Madison, in the county of Dane and State of Wisconsin, have invented a new and useful Shade and Curtain Adjusting Device, of which the following is a specification.

My invention relates to a device for attaching a shade roller of the ordinary automatic spring acting type, and a curtain rod for curtain or drapery to a window frame so that the shade roller and curtain rod may be adjusted to different vertical heights on the windowframe. The curtain rod and shade roller usually occupy positions near the top of the window frame, and thus prevent free ventilation of the room by lowering the upper window sash, but my device allows both curtain rod and shade roller to be lowered any desired distance within the limits of the mechanism and thus permit a free passage of air over both curtain and shade when top window sash is lowered. This ventilation is accompanied by no noise and rustling of the curtain and shade as with present construction, nor is the operation of the shade interfered with. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a front view of a two sash window and frame showing the shade roller and curtain rod with my adjusting device in highest position. Fig. 2 is a side View of the window frame, showing the adjusting device, shade roller and shade, and curtain rod and ourtain in same position of roller and rod as shown in Fig. 1. Fig. 3 is a front view of the adjusting device on larger scale than shown in Fig. 1.. Fig. 4 is a part side view and part section of the adjusting device, including the shade roller and curtain rod and brackets for both roller and rod. Fig. 5 is a section of the elements shown in Fig. 3 along line X-X. Fig. 6 is the cam unlock for lowering. Fig. 7 is an isometric view of a piece for attaching the spring spindle of the shade roller to supporting bracket. Fig. 8 is a cabinet projection of the element shown in Fig. 7 with one lug bent to position. Fig. 9 is a side view of the element illustrated in Figs. 7 and 8 attached to the spring of the shade roller. Fig. 10 is a cabinet projection of a device for replacing the ordinary spring spindle of the shade roller and the attachment illustrated by Figs. 7 and 8. Fig. 11 is a top view of a device for replacing the idler spindle of the shade roller so that the idler end of the roller may be attached to the supporting bracket.

Similar letters refer to similar parts throughout the several views.

The window frame A has attached to the upper portion of uprights the vertical double grooved strips B, shown in detail in Figs. 3, 4 and 5, the two grooves being shown at O C. A hollow block D has flanges E E guiding it in along the grooves C. Formed in the front face of block D are two lugs F and F in each of which is a vertical opening as shown at G, Fig. 5. Lug F carries shade roller bracket H, and lug F carries cur tain rod bracket H as shown in Fig. 4, the ends I and l" of these brackets fitting holes G in lugs F and F respectively, and the bracket ends I and J carrying the shade roller and curtain rod respectively. Secured to the inner face at the top of block D is the flat spring K. This spring is angularly formed at L to serve the purpose of a pawl and again bent at M as shown in Fig. 4.

Formed at intervals along strip 13 are a series of ratchet projections OO, etc. the number depending on length of strip B. The spring K forces the pawl L to engage with the ratchet projection O and holds block D and the shade roller and curtain red at any desirable height. On account of the spring K, this locking action is automatic when blocks D are moved upward so that pawl-L passes above a ratchet O.

In order to lower the shade roller and curtain rod, the shaft P is provided. Shaft P'which may be of any length depending 011 the height of the window, has a handle Q at its lower end by means of which P may be given a partial rotation. Shaft P is journaled in R which is attached to strip B, and in S which is attached to block D. A pin T passing through shaft P in a space between S and the main portion of block D forms a collar which prevents longitudinal motion of shaft P with respect to block D. The upper end of shaft P is cut down to a diametrical plane N, this plane bearing against the face of the end portion M of spring K, as shown in Figs. 4 and 6.

By partially rotating shaft P, the plane face N will raise M to position M (Figs. 4 and 6), disengage pawl L from ratchet O, and thus allow the blocks D and with them the shade roller and curtain rod to be lowered to engagement with any other ratchet tooth O. The pressure of end portion M of spring K on face N, due to spring in the latter, will restore shaft P to its normal position as shown by N, Fig. 6, when turning force is removed from handle Q. This normal position of shaft P allows pawl L to bear on the face of strip B so that pawl L will strike the next ratchet tooth 0 after turning force is removed from handle Q.

An integral part of my invention is means for attaching the spindles of the shade roller to my adjusting device. The spring end spindle is usually flattened, and to receive this flattened spindle I have provided the device shown in Figs. 7, 8 and 9. This consists of a piece formed as shown with a vertical rectangular opening U to receive the flattened spindle, a closing lug V and a projection having a vertical hole W, the latter to receive end J of bracket. After the flattened spindle is placed in opening U, lug V is closed by a blow, thus firmly uniting the two parts. The second lug V is closed when the piece is made.

Fig. 10 illustrates a method of attaching the spring end of the shade roller to my adjusting device by replacing the usual fiat end spindle with the device shown, in which the end Y is driven in the spindle socket and secured by pin Z. A hole W is provided to receive bracket end J as already described.

Fig. 11 illustrates a means for attaching the free spindle end of the shade roller to my adjusting device. A cap a, formed to fit over the end of the shade roller, has a sleeve 0, concentrically attached. A spindle b is fitted to this sleeve, one end of the spindle 0 being formed large enough to receive hole d and the other end headed as shown at f. Some longitudinal motion is allowed spindle b in sleeve 0 to accommodate varying lengths of shade roller and distances between fittings. A hole d is provided to receive one of the bracket ends .I as already described.

The operation of my adjusting device is as follows: A pair oi the adjusting devices shown by Fig. 3 is employed, one being attached to each upright oi the window frame as shown by Fig. 1. It the shade roller g and curtain rod h be at the position shown by Figs. 1, 2, 3 and 4, a slight turn of handle Q will release block D due to disengagement oi pawl L and ratchet O, and the shade roller and curtain rod may be lowered nearly as far as desired. After this height is reached, the turning iorce is removed from handle Q and the next ratchet tooth 0 below pawl K will engage the latter and hold the parts at that height. To raise the shade roller and curtain rod, an upward force is exerted on handles Q, this force being transmitted to blocks D by collar pin '1. The pawl L will pass upward over ratchet teeth 0, engaging the pair of ratchet projections 0 next below, when the upward force is removed from handles Q.

What I claim as my invention and desire to secure by Letters Patent oi the United States, is

1. The combination, in a shade and curtain adjuster, of a double grooved base strip, a double flanged hollow block, having flanges fitted to grooves in base strip, ratchet teeth on base strip, a spring actuated pawl attached to interior of hollow block and engaging ratchet teeth on base strip,

and a shaft with a cam formed as part of said shaft, so

arranged that partial rotation of shaft will cause cam to disengage pawl and ratchet, substantially as described.

2. In a shade and curtain adjuster, the combination of a vertically adjustable block, a shade bracket and curtain bracket attached thereto, a base Strip guiding said block, a spring pawl on said block, ratchet teeth on said base strip and a shaft journaled in said adjustable block, with a cam formed on end of said shaft for operating spring pawl, substantially as described.

3. In a shade and curtain adjuster, the combination of pair of vertically guided and adjustable hollow blocks D, a curtain bracket H and a shade bracket H attached to each hollow block D, a curtain rod h attached to curtain brackets H, a shade roller y, and a block having rectangular opening U and closing lugs V V for attaching spring spindle of shade roller to one of shade brackets H, with a shade roller end formed of cup a, concentric sleeve 6 and headed spindle f for attaching idler end of shade roller g to one of shade brackets H, substantially as described and for the purposes set forth.

In testimony whereof I have signed my name to this specification in the presence of two witnesses.
