March 17, 1931. a. w. HAWKINS AWNIIKIv PULLEY AND THE LIKE Filed June 3. 1929 Patented Mar. 17, 1931 UNITED STATES PATEN T OFFICE" AWNING PULLEY AND THE LIKE Application filed. June 3,

My invention relates to means for raising and lowering window awnings and the like by means of a pulley-block, and relates more particularly to a block of special form to be located at one side of a window frame, adapted to receive not only a cord coming up from that side of the awning, but also a cord coming transversely across the window from another pulley over which it has passed and which is connected with the other side of the awning.

One of the principal objects of the invention is to provide a duplex or double-acting block such as is above referred to, in which two cords, one coming up from one lower corner of the awning, and the other coming across from the other side of the Window and thence from that corner of the awning, may be housed, each of said cords having provided therefor a pulley forming part of said block and rotating in a plane substantially parallel with the direction of movement of the cord. Further objects and advantages of the invention will be in part set forth in the following specification, and in part will be obvious therefrom without being specifically pointed out, the same being realized and attained by means of the instrumentalities and combinations pointed out in the claim hereof.

In the practice of raising and lowering awnings, it is usual to provide a cord attached to each front corner of the swingingly mounted awning frame. One of said cords is led upward to the top of the window and over a pulley and down again to a point convenient for manipulating the same. The other of said cords, attached to the other corner of the swinging frame, is led up to the top of the window, over a pulley, and then horizontally along to the other side of the window, and then through a pulley at the first-named side of the window, the last-named pulley being either entirely separate and distinct and in a separate shell from the first-named pullev over which the first-named cord passes, or else, if in the same shell, then being in substantially the same plane as the first-named pulley. In either case, the operation of the cords in raising or lowering the awning is unsatisfactory and ineflicient. By the use of 1929. Serial No. 368,174.

adevice such as my invention which is hereinafter fully described, these disadvantages are obviated.

With the above and other objects of the invention in view, the invention consists in the novel construction, arrangement and combination of various devices, elements and parts, as set forth in the claim hereof, one embodiment of the same being illustrated in the accompanying drawings and described in this specification.

In the accompanying drawings,

Fig. 1 is a perspective View of a device embodying my invention, showing the same hung 1n position upon awindow frame;

Fig. 2 is a transverse section along the line 2-2 of Fig. 1;

Fig. 3 is a back view of Fig. 1; and

Fig.4: is a top view of the same.

In carrying my invention into effect in the embodiment thereof which I have selected for illustration in the accompanying drawings and description in this specification, I i provide a shell or w pulley-frame of special form as shown in the drawings, being duplex or adapted to contain two pulleys or sheaves. The frame comprises two wings or sheavebear ng members 11, arranged approximately at right angles to each other. The pullevshell is hollowed out so as to receive the 30 sheaves 12, and the same is also provided with openings in the front as shown in Fig. 1 and in the back as shown in Figs. 2 and 3.

The pulleys 12 are secured in the pulleyframe in any suitable manner, as for instance by pintles 13, and the pulley frame is provided with a hook 14 which is adapted to be secured to a supporting hook 15 inserted in r the frame of the window or other supporting structure 16.

The operation of my invention is as follows: Referring more particularly to Fig. 1, 16, 16, represent portions of the front and side of a window frame, located substantially at right angles to each other, the pulley being suspended from a point near the angle, and the right-angled wings 11 of the pulley being located in the corner or angle of the window frame. Assuming that the right-hand member is at the side of the window, a cord is brought up from the corner of the swinging frame of the awning and passes over the pulley 12 at that side of the device, and is allowed to drop down again into a position suitable to be manipulated to raise or lower the awning. Another cord is brought transversely across the window frame from the other side of the awning, and passes down over the pulley 12 on the left hand side of the block, the two cords being grasped together and operated so as to raise both corners of the awning at the same time. Owing to the fact that each cord has its own pulley in the shell or pulley-frame, and that the pulleys rotate in planes in which the cords are respectively passing, no entanglement of the cords, or jumping of the cords out of the gorge of the pulleys, is possible, neither can. there be any undue friction.

The advantages of my invention have been fully set forth in connection with the construction and operation of the same.

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

A swivel-suspended pulley-block adapted for raising and lowering awnings, comprising a shell having two portions each of which is approximately one-half of the size of the shell as a Whole, said two portions being integral with each other and substantially at right angles to each other, and a swivel-hook member located at the top of said shell and at the angle formed by the two sides thereof, each of said half portions of said shell containing a rotatable pulley, whereby a duplex block is formed having two pulleys rotating at right angles to each other.

In witness whereof I have hereunto signed my name this 27th day of May, 1929.

GEORGE XV. HAWKINS.
