CLOTHESLINE PULLEY.

Application led January 24, 1923. lSerial No. 614,528.

To a! whom t may concern:

Be it known that l, HANS ADELMANN, a citizen of the United States, residing .at New York city, borough of the Bronx, in

'c the county OffBronx and State of'NeW fc-rk, have invented certain new and useful mprovements in. Glothesline Pulleys, of which the following is a specification.

rihis invention relates to pulleys such as are used for the hanging of endless clothes lines or other analogous ropes or cords.

Among the objects of the invention is to provide a pulley including a frame, so designed or constructed as to make it impossible for the line to become wedged between the wheel and the frame and which will permit free transmission through the frame of the knot or knots that may be formed in the line.

[another Object of the invention is t-o provide an improved form of guard or shackle the plane of which is at right angles to that of the frame, and so constructed as to make it impossible for the line to become snarled or fouled while passing the wheel. I

A still further object of the improvement is to improve the means for assembling the several parts of the pulley as to make it not only reliable and rigid but also of the neatest and most practical nature.

With the foregoing and other objects in view the invention consists in the arrange ment and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or .suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which likeI reference characters designate the same parts in the several views, and in which-` Figure 1 is a side elevation of my improved pulley.

Fig 2 is a vertical transverse section on the line 2-2 of Fig. 1. Y

Fig. 3 is a plan view of the shackle show ing its preferred form and indicating in dot and dash lines its relation to the wheel.

By the term pulley as used herein I Wish to be understood as covering the entire construction to avoid confusion of terms with respect to the wheel of the pulley.

Referring now more specically to the drawings l show my improvement as comprising three and only three principal parts,

a frame l0, a wheel 11 journaled within the frame, and a shackle or line guard 12. These three parts 'are assembled and held permanently in fixed relation to one another by means of.l a pivot bolt 13, the ends of which are preferably upset to make as neat a construction as possible. Y

The frame comprises a structure of generally U-shapc having Atwo spaced leg por'- tions 1()a terminating in bearings having aligned holes 14 through which the bolt 13 projects. The top or crotch portion 15 of the frame is provided with a hanger hole 16 next adjacent to which portion the sides of the frame are looped outward forming a large Oval or curved opening 17 joined to the straight portions of the legs at shoulders or knees 18, the two knees being spaced from each other approximately the same distance as the width of the periphery of the wheel and directly between which knees the periphery of the wheel rolls. The leg portions of the frame diverge from said knees toward the pivot bolt, and located between the bearing portions of the legs is a hub portion 19 of the wheel, the ends of which are adapted to bear against one or the other of said bearing portions of the leds to prevent undue movement of the wheel lengthwise of ther pivot.

The Outer or remote sides of the bearing ends of the legs are recessed at 2O for the reception of the shackle 12. This member comprises two parallel sides 21 having holes 22 registering with the holes 14 and through which the pivot bolt passes as shown in Fig. 2. The depth and width of the recesses or notches formed in the legs corresponds exactly to the cross section of the fiat portions 21 of the shackle so that the outer surface of each iiat portion constitutes a continuation of the outer surface of the adjacent frame leg. Each flat portion of the shackle is locked in rigid position with respect to the plane of the frame at right angles, the upsetting of the pivot bolt serving to make the structure practically integral, but with the wheel free to spin around the pivot bolt. The end portions 23 of the shackle correspond approximately in shape to the opening 17 of the frame, leaving ample Vroom for any knot formed in the line to pass freely therethrough in either direction. The portions 2e of the shackle between the at sides 21 and theloopsV Qare bent inward into close proximity'to theflanges 25 o'fthe Wheel.

As shown in Figs. l and 2 the body of the Wheelis providedwith a'succession of pits 26 which are designed to receive the knots of 1Q Y i 1,476,787

in pivot ends, a Wheel rotatable within the frame, an endless shackle connected to the remote outside portions of the pivot ends of the frame at right angles to the plane of the frame, and a pivot bolt passing through the sides of the shackle, the ends of the frame, and the hub of the Wheel, holding said parts permanently together, the outside portions of the pivot ends of the frame being recessed to receive the side portions of the shackle, the cross section of the shackle sides being the saine as the depth and Width of said recesses, and the end portions of the shackle being looped to form `enlarged openings for thepassage of knots `formed inthe line.
