CLOTH ES-LINE PU LLEY.

SPECIFICATION forming part of Letters iatent No. 597,765, dated January 25, 1898.

Application filed March 22, 1897. Serial No. 628,792, (No model.) 7

To ttZZ whom it may concern.-

Be it known that I, STEPHEN SUMRIX FAIR- MAN, a citizen of the United States, and a resident of New York city, in the county and State of New York,havc invented certain new and useful Improvements in Clothes-Line Pulleys, of which the following is a specification.

Hy invention consists of an improved construction of clothes-line pulleys, designed to provide a simple and inexpensive pulley adapted for carrying an endless line with clothes on it around the turn at the outer extremity of the line in a horizontal plane, or practically so, as hereinafter described, reference being made to the accompanying drawings, in which' Figure 1 is a perspective View of the improved pulley with part of a line and clothes thereon, illustrating the operation of the pulley. Fig. 2 is a sectional elevation of the pulley and line on line m, Fig. 1.

I provide two stamped or equivalently-constructed disks a and b of sheet metal, each 2 5 with a central perforated hub cdrawn to one side of the disk out of the metal displacedin forming the perforations for application to a center pivot d,and each disk also being formed with radially-extended prongs or sprockets, 0 which are produced by forming notches in the outer margins of the disks, which prongs are bent and expanded laterally to the plane of the pulley for producing the'rope-carrying groove, and the notches eintermediate of the 3 5 sprockets are forlodgmentof the clothes-pins I", so as to admit the line 9 into the groove, said disks being coupled side by side, as shown, with the hubs in opposite relation to each other and together forming out of thin sheet metal a bearing of suitable length and surface for practical use, said disks being soldered or otherwise fastened together. The sprockets 72, of the upper disk and 21 of the lower disk are expanded uniformly, or nearly 5 so, at their bases, as best seen in Fig. 2,-and sprockets h are expanded continuously from the base outwardly, the expansion or outward flare of which is increased a little at the extremities for better efiect in catching the line as it runs on the pulley, but sprockets t' are formed with a considerable return or reentering bend j outward from the expanded base, the purpose of which is to retain the line to better advantage against the tendency of the clothes in, heavy with water, to pull the line out of the groove of the pulley, particularly at times when the line is slack, andpreferably at some greater distance below the disk I) wire ring Z is suspended from the extremities of sprockets iby wires in to prevent the clothes from catching on said extremities and obstructing the lodgrnent of the line within the line-carrying groove.

The pulley thus constructed is suspended on a pivot 01 of any approved bracket 71, suitably deflected to give a downward pitch in the plane of the pulley in the direction from and to which the line runs, that favors the running of the loaded and sagging line into the groove of the pulley.

It will be seen that the construction of the pulley in two stamped disks, forming respective half parts soldered or riveted together, is a very simple and cheap-way of producing such pulleys, and the reentering curves of the sprockets of the lower disk is a simple and edective device for insuring retention of a heavily-loaded line upon a pulley whose plane is horizontal or practically so.

I claim as my invention So The improved clothes-line pulley herein described consisting of two stamped disks of sheet metal each formed with a drawn perforated hub, and with laterally-bent sprocketpoints both projected in the same direction from the plane of the disk, said disks connected together side by side with their lateralprojections oppositely directed, the sprockets of one disk having the reentering curve for retaining the rope, and the guard-wire 9o suspended at a distance from the points of the said renterin g sprockets by pendent wire supports, substantially as described.

Signed at New York city, in the county and State of New York, this 9th day of March, A.,D. 1897.

STEPHEN SUillRlX FAIR-MAN.
