PULLEY-LINE SUPPORT.

Specification of Letters Patent.

Patented Mar. 15, 1921.

Application filed October '15, 1920. Serial No. 417,107.

T 0 all whom it may concern Bev it knownthat I. CHRISTOPHER ANDER- soN, a citizen of the United States, and a resident of Harrison, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in Pulley- Line Supports, of which the following is a specification.

This invention relates to an improved support for. pulley lines which can be swung out of the way when it is not used, but can be securely fastened in position to permit easy manipulation of the line.

The invention consists of certain details of construction which will be hereinafter more fully described and finally embodied in the claims.

The invention is illustrated in the accompanying drawing. in which Figure 1 is a top view of my improved pulley line support, and Fig. 2 is a front view thereof. Fig. 3 is a detail section on line 33 in Fig. 2, and Fig. 4 is a view showing one manner of securing the device in various positions.

The support is preferably fastened to any part of a building, usually a window casing or porch, which support is illustrated at 10, and a supporting fixture 11 is secured in position and this in turn supports the swinging bracket 12, which preferably consists of parallel arms 13 which are hinged at one end, as by the bolt 14., to the ears 15 of the fixture 11 and are spaced apart and also braced in such spaced position by suitable tie-rods 16. The arms 13 are obliquely a ranged at their outer ends, as at 17. and are, utilized to support, by means of the eye or.v knuckle 18. the box 19 which supports thev pulleys.

The swinging bracket 12 is usually in ther supported by means of a bracing rod 20 fastened at its outer end to the top arm 13, and on its upper end swinging on the p1v= cars 18 are fastened to the ends of the swinging bracket by a bolt 22. In order to permit the securing of the box in adjusted posi' tions I provide a bar 23 which is fastened to the side of the box. as at 24, and slides under the top arm 13. A. clamping bar 25 is arranged over the top arm 13 and screws 26 passing through the plates 23 and 25 clamp these plates in position to lock the box 19 in its adjusted position.

Thebox 19 is provided with two shaft 27 and 28 which are provided with gears 29 which are in mesh.v so that the shafts will rotate together, and one of the shafts, such as the shaft 28, has its two ends extending from the box or casing 19 so that it can be used either right or left'handed by attaching the hub 30 of the crank, handle 31 to either of such projecting ends 32 of the shaft 28.

A pulley 33 is secured to the shaft 27 and a pulley 34: to the shaft 28, the pulley 3i be ing made wide enough so that the pulley line 35 can be passed over the pulley 34 and once around it and then around and over the pulley 33. In front of each of said pulleys. that is, centrally located at the open end of the box 19, are arranged wires 36 which have their extremities secured in the side wall of the box and are formed intermediate of said ends into loops 37 which loops act to guide the pulley line to and from the pulleys and prevent the line from jumping from said pulleys, whereby the smooth op eration of the pulley line is always assured.

It will be evident from this description that the device can be used either righthanded. or left-handed. since if it is to be used to the left it is only necessary to turn the swinging bracket upside down and place the handle 32 on the other end of the shaft 28. and the locking bar 23, with its clamping bar 25., secured to the other side of the box. provision being made for this by placing perforations in both sides of the box to receive the screws 38. by means of which the bar 23 is secured.

In pulley line supports an essential is stability, and as the pullev line is usually used but a short while with heavy loads on it, it is desirable that a device he provided that combines such stability with ease of operation and adaptability for swinging it Qfrom its normal holding position when it is otal bracket 2 secured above the fixture 11.; I

The box 19 is arranged to swing. since tha .y In Fig. 4 I show roughly one form of holding this device in position. which means gincludes a bracing cord 39. which is usually piece of rope, such as sash cord or clothes line. which is fastened. for instance, as at to one of the tie-bars 16, and two hooks 41 "7* 42 are provided. secured at suitable places on the back porch or alongside the support of the line. the hook 42, for instance, being used when the device is employed in holding the pulley line with clothes on it,

and When the line is not in use and it is desired to slacken it, the hook or eye 41 is used. This makes it possible to use the line and keep it taut, and also to let the line hang relaxed, without untying and re-adjusting the line itself. 7

permit the pulley line to be passed once around before proceeding to the other pulley.

2. A pulley line support comprising a swinging bracket, an open-ended box secured to the end of the bracket, 21- pair of shafts in the box, gears on the shafts,fa 20 handle on one shaft, pulleys on the shafts, and wires extending across the open end of the box, the wires being formed into closed loops for guiding the pulley line. 7

3. A pulley line support comprising a 25 supporting bracket adapted -to swing, a box pivotally secured to'the end of the bracket, means within the box for supporting pul-; leys, a handle for operating the pulleys, and a bar secured to the box and adjustable rel- 30 ative to the bracket.

In testimony that I claim'the foregoing, I have hereto set my hand. this 11th day of October. 1920. r

CHRISTOPHER ANDERSON.
