CLOTHES-LINE PULLEY.

Specification of Letters Patent.

Patented July 24, 1906.

Application filed June 30, 1905. Serial No. 267.766.

To all whom, it may concern:

Be it known that I, HANNA KOORIE, a citizen of the United States, residing in Paterson, county of Passaic, and State of New Jersey, have invented certain new and useful Improvements in Clothes-Line Pulleys; and I do hereby declare the following to be a full, clear, and exact descri tion of the invention, such as will enable ot ers skilled in the art to which it 'appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, 'which form a part of this specification.

This invention relates to clothes-line pul-v leys, and has for its object to provide a device of this nature with means for preventinglat will the pulley proper from rotating in eit e r direction and the rope from slipping on the pulley under the weight of the clothes.

A further object of the invention is to provide a clothes-line pulley of simple, strong,

and durable construction, easily manufactured and handled, and reliable and effective in o eration.

T e invention consists in the improved clothes-line pulley7 its double-acting springcontrolled pawl, and in the combination and arrangement of the various parts, substantially as will be hereinafter more fully described and inally embodied in the clauses of the claim.

In the accompanying drawings, Figure 1 is a side elevation of my improved clothesline pulley 5 Fig. 2,'a view similar to Fig. 1, the front section of the pulley-frame and the pulley removed; Fig. 3, a top plan view of ig. 1, the fastening-hook not being shown and Fig. 4, a cross-sectional view on line a; of Fig. 1.

In the drawin s, a is the pulley-block, consisting of two ha ves or sections b and c. One of the sections (in the drawings b) is provided with two projecting pins or studs d and e, penetrating the other plate or section c and ada ted to have their ends riveted over said p ate or section c, as at d and e', or secured thereto in any desired manner. Also projecting inwardly from the plates b and c are centrally-arranged pins or studs f and g, meeting about the central portion of the block and forming a pin or axle for the pulley h, which latter is preferably of porcelain or other vitreous material.

The plates b and 'c,'whose major portions are of substantially. circular form, are likewise provided at opposite sides with inwardly-extending projections b c', enga each other in the central plane of the pu eyblock and forming braces for the latter, as will be manifest.

Upon the inner pin or stud d is pivotally mounted a double-ended pawl i, having its outer faces serrated orcorrugated, as at i t, and adapted to bear and bind against the clothes-line m in a manner hereinafter described. The central portion of saidl pawl i is provided with a socket n, in which is arranged a spiral sprin o, the. other end of which bears against the extreme portion of a recess or socket p, which latter is provided for in the fastening end g of the pulley-block. It may be well to remark thatadditional strength an stiffness may be imparted to the pulley-block by providing the meeting portions of the various projections of the two sections b and c with any suitably-shaped tongue-andoove arrangement, such as is shown for i-ilstration at r and s in Fig. 4 and at tin Fig. 3.

When the serrated end ortion 'i' of the pawl 1', is in engagement wit the clothes-line m, as shown in Fig. 1, the spiral spring o will hold said pawl in that position, and the greater the pull onthe rope in the direction of the arrow, Fig. 1, as under the weight of the clothes hung on the lower ortion of the line m the greater will be the inding action of the pawl to prevent the rope'from runnin over or around the pulley. If it is desire to pull the rope in the direction of the arrow shown in Fig. 1, the serrated section 'i' of ypawl 'L is disengaged from the ro e and the serrated section 2 of said pawl is t own into engagement with the rope, whereby the rope can be pulled in the direction of the arrow, but is revented from running over or with the pulley in the opposite direction. The spring o acts to maintain the pawl at either of its two limits of movement where either the one or the other of its serrated end portions bears against the rope.

I do not intend to limit myself to the precise construction shown and described, as various alterations can be made without changing the scope of my invention; but

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the pulley-block, the pulley plroper 'ournaled therein, a pawl pivoted in t e loc in the same plane as the pulley and with its axis parallel with the axis IIO of the pulley, said block having a socket disa spring arranged in said socket and interposed radially of the pulley, and a spring arposed between the end thereof and said pawl, ranged in said socket and interposed between substantially as described.
