Vv.Application'lled October 27, 1932. Serial No. 639,884. I

The present invention relates to a device for fastening lines, such as ropes, cables or the like and chiefly for holding clothes lines taut, the invention being specifically applied to that class in which a clothesline .is passed over pulleys attached to supports and connected at its ends so as tofform an endless line which may be shifted in different directions.

The object of the invention resides in the provision of a device of this nature which is exceedingly simple in its construction, inexpensive to manufacture, easy to manipulate, thoroughly eflicient and reliable in use, compact and convenient in its arrangement of parts and otherwise well adapted to the purpose for which it is designed.

jects in view as will appear as the description proceeds, the invention consists in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

Figure 1 is a side elevation of a device embodying the features of my invention.

Figure 2 is a plan view thereof..

Figure 3 is a longitudinal section therethrough,

Figure 4 is an end elevation thereof.

Figures 5 and 6 are transverse sections taken respectively on lines 5 5 and 6 6 of Figure 3, and

Figure 7 is a perspective view of the locking jaw. A

Referring to the drawings inl detail it will be seen that the numeral 5 denotes an oblong body formed at one end with a pair of spaced upstanding parallel coextensive ears 6 through which an axle pin 7 extends and on this pin 7 is rotatable a pulley 8 having a grooved periphery. The ears 6 have inwardly directed extensions 9 which mergeV into a transverse lug 10 rising from the central portion of the body 5 and apertured to slidably receive a shank 11. Fixed to the shank 1l is a wedge shaped locking jaw 12 the inclined face of which is provided with ratchet like lteeth 14 to engage a rope or the like which has been extended tension of the .jawfrom the ro Vextending bore 420 so that the pulley as is indicated to advan- -tage 4in Figure. A spring lvisdisposed about the shank 11 and is ofthe coiltype and. i'mpinges against the lug 10 and against the jaw :12 so as tofurge the jaw l2 to a normally locking position. .A knob 17.pro

ject-s laterally Afrom the jaw 12 vthrough a slot 18 in one of the ears 6 sovtha'trthe knob may be .used to move Vthe jaw against the a pe when so desired. Atthe other end of .the body there rises therefroma lug 19 having a` longitudinally y onevend'of therope may be passed therethrouglrand-knottedv as fis indicated to advantage in Figures 12'and -3- of the drawings.. With the above and numerous other ob- It will be readily appreciated from the above detailed description thatY after Vone .end ofthe rope has.v been engagedwith Vthe lug the other end of the rope may be passed underfthe pulley,J that isbetween the pulley and the body, and-drawn Vtightly and when released will be locked by the wedging action of the jaw on the rope against the pulley.

The present embodiment of the invention has been described in considerable detail merely for the purposes of exemplification since in actual practice it attains the .features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described our invention, what we claim as new is: A p
