UNITED STATES PATENT OFFICES 2,602,951 SELF-LINE CLEANING PULLEY William H. Zimbalist, Brooklyn, N. Y. Application July 3, 1948, Serial No. 37,019 g 8 Claims.

characters in each of the views and, in which:

Fig. 1 is a longitudinal sectional view through a pulley made according to my invention, indieating a clothes line in dot and. dash lines.

Fig. 2 is a section On the line 2-2 of Fig. 1 with part of the construction shown in elevation and with parts broken away.

Fig. 3 is a section on the line 3-3 of Fig. l; and

Fig. 4 is a detailed view of one of the wiper elements which I employ, detached.

In the construction shown, I provide a pulley which is fashioned from two substantially similar casing parts l6, If), each part having inwardly set hub portions l I, II for support of the pulley axis l2 in the form of a rivet pin. The casing parts, when assembled, by riveting together two projecting flaps or flanges l3 as by the rivet I4, and by turning-over hook flange portions, as at I5, form a disc-type casing having two tubular admission and discharge extensions, as at It and II, as clearly illustrated in Fig. 1 of the drawing, and also shown in Fig. 3 of the drawing. The hook-shaped flanges l5 are formed on wall portions 18, which join the tubular portions II, as clearly seen in Fig. 3 of the drawing and these wall portions are pressed outwardly to form a longitudinal channel I9 for purposes later described.

Mounted on the rivet pin M is a coupling or hanger loop 20.

Arranged around the axis I2 are a series of ball bearings 2|, note Fig. l, which are arranged between the separate parts 22, 22' of the pulley which is disposed in the casing, these pulley parts beingsecured together by welding, as indicated at 23 in Fig. 1 of the drawing. In conjunction with the casing or the separate parts [0, l0 thereof, still more particularly, in connection with the tubular extensions l6, l! are two similar wiper elements 24, each element comprising a twisted wire strand having a long mounting end 25 and a short mounting end 26, the intermediate portion of the strand having a suitable brush body 21 of ring-like or annular construction. In. other words, that part of the twisted strand, on

Ids-256.6)

. 2 which the brush body is arranged, is shaped into circular form, so as to provide an opening 28 centrally of the brush body which is preferably smaller in diameter than the outside diameter of the clothes line tobe passed therethrough, which clothes line is indicated in dot-dash lines at 29 in Fig, 1 of the drawing and also indicated in Fig. 3 of the drawing. In assembling the parts of the pulley casing, two of the elements 24 are arranged between the walls It in the channel I9 with the long ends 25 of the elements overlapping each other, as clearly seen in Fig. 3 of the drawing. In final assemblage of the casing parts, the walls l8 are preferably crimped together, as indicated at 30 in Fig. 3, so as to securely bind the elements 24 in position to maintain the openings 28in suitable centralizedposition within the tubular portions 16 and H of the casing. 7

With this construction, it will be apparent that, as the clothes line 29 is passed around the pulley, the clothes line will be frictionally passed through the circular or ring-like wiper elements, or brush bodies 27 of the wiper elements and any deposits that may be present on the line will be removed and the line kept clean for the intended use. It will be recommended that, preparatory to using the line, the line will be run through the pulleys a number of times for this purpose.

By constructing both parts of thecasing and the pulley of similarly shaped members'and'by utilizing two wiper elements o-f similar construction, the cost of producing the entire device is materially simplified. Thus the pulley can be sold at a relatively reasonable price. While in the present construction, I haveillustrated certain types of wiper or cleaner elements, the structure of these elements may be modified to suit the intended uses, particularly in pulleys of any type or kind. In some instances, where a strand-like body is passed around a pulley member, these elements may be utilized for any purpose consistent with the results that may be desired.

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

l. A clothes line cleaner comprising two substantially similar casing parts forming a hollow body, in which a pulley is mounted for free rotation, tubular projections on said body, the easing parts having abutting wall portions between said tubular projections, said wall portions having registering recesses on adjacent surfaces thereof opening into said tubular projections, wiper elements arranged in the tubular projections and having overlapped mounting ends disposed in said recesses, means securing the casing parts together, and means retaining the mounting ends of said elements within and against displacement from said recesses.
