l Claim. 1

This invention relates to window sash operating devices and in particular rods and levers attached to window sash to facilitate opening and closing the sash where Venetian blinds are used and wherein the sash may be moved without drawing the blinds upwardly to the upper end of the window frame.

The purpose of this invention is to provide means for opening and closing window sash with Venetian blinds hanging over the inner surfaces of the sash.

Where Venetian blinds are used in combination with windows it is difficult, and substantially impossible to raise and lower the sash without draw ing the Venetian blinds upwardly to positions, at least above the center of the window. For this reason numerous devices are used to raise and lower window sash by holding the Venetian blinds outwardly and this pulls the blinds from the supporting elements at the upper ends of the window frame. With this thought in mind this invention contemplates operating devices formed to be attached to the surfaces of window sash with the attaching elements positioned between the ends of the slats of a Venetian blind and the sides of the window frame and connected by cross rods and also in which clamping elements are provided by which the sash may be locked in adjusted positions.

The object of this invention is, therefore, to provide means for attaching operating elements to Window sash whereby sash can be raised and lowered with Venetian blinds hanging over the inner surfaces of windows.

Another object of the invention is to provide window sash operating instrumentalities for raising and lowering window sash with Venetian blinds hanging over the inner surfaces that may be attached to sash of double hung windows without changing the sash, window frame or Venetian blinds positioned thereon.

A further object of the invention is to provide a window attachment for operating sash of double hung windows with Venetian blinds positioned on the inner surfaces of the windows which is of a comparatively simple and economical construction.

With these and other objects and advantages in view the invention embodies a tube having a shaft therein extended across a window and adjustably attached, with brackets, to the sides of the sash and also having clamping elements on the ends positioned to engage the sides of the window frame for clamping the sash in adjusted positions.

Other features and advantages. of the invention will appear from the following description taken in connection with the drawings wherein:

Figure 1. is a front elevational view showing a window with the operating devices mounted. on upper and lower sash thereof.

Figure 2 is a cross section through the window taken on line 22 of Fig. 1 illustrating the mounting of the operating devices.

Figure 3 is a detail showing a section taken on line 3-3 of Fig. 2 illustrating a mounting element at one side of the window, and showing the parts on an enlarged scale.

Figure 4 is a longitudinal section through one of the sash operating devices taken on line 4-4 of Fig; 6 and also showing the parts on an enlarged scale.

Figure 5 is a detail showing a section taken on line 55 of Fig. 2 illustrating a lever or handle for operating the device.

Figure 6 is a detail illustrating one of the clamping elements mounted on the ends of the rods.

Referring now to the drawings wherein like reference characters denote corresponding parts the window sash operating device of this invention includes a tube It), rods II and I2 journalled in the tube, brackets l3 and [4 for mounting the tube on a window sash I5, an arm l6 mounted on the tube, a coacting lever I1 for actuating the rods, and shoes l8 and I9 carried by the ends of the rods and positioned to engage the inner surfaces of the sides of a window frame.

The tube I0 is provided with an enlarged section 20 at the center to which the arm l6, having a knob 2| on the outer end is attached, the inner end of the arm I6 being secured, preferably by welding in a slot 22 in the upper surface of the enlarged section 20 of the tube.

The section 20 of the tube I0 is also provided with an elongated slot 23 through which the lever I1, which is also provided with a knob, as indicated by the niu'neral 24, extends, the inner end of the lever I! being secured in an opening 25 in a sleeve 26 in which the ends of the rods H and I2 are secured, preferably by welding.

The outer ends of the tube It extend through

sleeves

21 and 28 which are provided with set screws 29 for securing the tube in position in the sleeves. The sleeves are mounted on cylindrical arms 30 and 3| that are secured by set screws 32 on rods 33 which extend outwardly from brackets I3 and I4 and, as illustrated in Fig. 2, each of the brackets l3 and I4 is provided with a foot or flange 34 and also an offset sec- 3 tion 35 to provide clearance for supporting struts or beams at the lower ends of Venetian blinds 36.

The outer ends of the rods H and 12 are provided with heads 3! and 38 in which the rods forming the shoes 18 and 19 are carried and the heads are secured on the ends of the rods by set screws 39.

As illustrated in Fig. 4 each of the

heads

31 and 38 is provided with an annular recess 40 and the ends of the tube I!) extend into the said recesses. By this means the heads are free to rotate in the ends of the tube and the rods are resiliently held with the shoes in engagement with the surfaces of the side members 4| and 42 of a window frame by springs '43 that are mounted, with one end extended into openings M in the rods I I and I2, and the other into openings 45 in the end of the tube Ill.

With the parts provided and mounted in this manner, and the brackets 13 and id attached to the inner surfaces of the sash, by screws 45, the sash will be stopped by the shoes :8 and !9 which are shaped to clamp the parts in position until the shoes are moved outwardly by the handle or lever 17.

The handle or lever I1 is moved upwardly toward the arm 18 whereby the shoes l8 and I9 move away from the surface of the window frame and with the parts in this position the sash are readily moved upwardly or downwardly to open Or close the window as may be desired. With the sash in the desired positions the handle 11 is released and the springs 43 urge the shoes against the inner surface of the window frame.

As illustrated in Figure 1, the shoes 18 and [9 on the tube Ii] of the lower sash extend upwardly and the shoes on the tube or rod of the upper sash extend downwardly, whereby the shoes of one sash point toward the shoes of the other sash.

, 4 The stationary handles I6 extend from the sides of the tubes opposite to that from which the shoes or clamps extend.

It will be understood that modifications may be made in the design and arrangement of the parts without departing from the spirit of the invention.

What is claimed is:

In a window sash operator, a tube having an enlarged central section, a sleeve rotatably mounted in said enlarged section, a pair of rods extending inwardly from each end of the tube and attached at their inner ends to said sleeve, a mounting bracket at each end of the tube, an arm fixed to the said enlarged section, said enlarged section having an elongated slot therein and a lever extending through the slot to be fixed to the sleeve for the rotation of said sleeve and rods, a surface engaging shoe at the outer end of each rod adapted to be moved into or out of surface engaging position by said lever, a spring means positioned on each of said rods for urging said shoes into surface engaging position, a sleeve mounted on each end of the tube and a cylindrical arm fixed to each bracket and extending outwardly thereof to engage and support the sleeves on the outer ends of the tube.
