' ROPE LOCK.

Application filed July 31,

This invention relates to rope locks and in particular to one adapted for use in connection with clothes lines.

A particular object of the invention is to provide a line lock or rope connector which will eliminate the necessity of tying the ends of the rope together and which will securely hold the ends of the rope in their proper spaced relation.

It is well known in the tying of knots, for instance, in a pulley line, that damp weather causes the knots to bind so tightly that it is often impossible to undo the knots. In order to eliminate the necessity of making any knots, I have provided a rope lock having a locking member which is arranged to jam the rope end, the locking piece being so arranged that the harder the rope is pulled away from the rope lock, the greater will become the holding pressure of the locking piece.

It is therefore an important object of my invention to provide a rope lock-in which the ends of the rope may be inserted with a minimum of time and effort and one which will securely hold the ends of the rope firmly together.

To enable others skilled in the art to fully comprehend the underlying features of my invention that they may embody the same in the various modifications in structure and re lation contemplated, a drawing depicting a preferred form has been annexed as a part of this disclosure and in such drawing, similar reference characters denote corresponding parts throughout all the views, of which,

Figure 1 is a view in side elevation, a part thereof being broken away to illustrate my improved rope lock, the lock piece being shown in position to lock a piece of rope therein.

Figure 2 is a bottom plan View of the rope lock as illustrated in Figure 1,-the lock piece retaining screw being clearly illustrated, and

Figure 3 is a view in side elevation of a modified form of my invention in which two lock pieces are employed to hold the joining ends of a rope, this lock piece being so arranged that either end of the rope may be ad justed therein.

Referring to the drawings in detail, my im- 1925. Serial No. 296,570. It

proved rope lock consists preferably of a cast member comprising a top 5 which terminates at its ends in a thickened portion 6 in which are provided openings 7, these ends providing rope eyes for the passage therethrough of the rope 8, or cable, it of course being understood that my locking device is applicable to any kind of rope, cable or tying member. a

Cast integral with the top 5,, are the depending sides 9,which form ahousing for the lock piece 10 which is pivoted as at lljtherein through the medium of the pivot pin 12 which may be peened over on one end to securely retain the same in position. The lock pieceis substantially the width of the housing formed by the depending sides 9 and is shaped in an eccentric fashion to provide a locking surface 13 which may be grooved to permit the rope 8 to seat therein, although this is not necessary. This locking part 13 jams the rope 870 against the top 5 and securely holds the same within the v rope lock. It is particularly pointed out that the lock piece is eccentrically mounted so that anv size rope may be acconr modated in the rope lock. e I

In order to maintain'the lock piece in its jamming position, Ihave made use of a retaining screw 14 which is threaded into one side 9 of the rope lock and is so arranged that its inner end will bear against the surface of the lock piece 10 and will, of course, retain the same in any position to which it may be set. The manipulation of the lockpiecelO is carried out by operating the handle 15 which is of an extended nature'and is provided with a pawl end 16 to facilitate holding the same. This arm 15 andlock piece are integrally cast as is theholder or frame therefor, it being evident that there being only four separable pieces, going to make up my improvedrope lock, all of which can be quickly and efficiently turned out permitting the rope lock to be sold at a minimum cost.

In the modified form shown in Figure 3,

use is made of a holder 17 which is cast in one 95 piece and comprises a top 18similar to the top shown in Figure 1 and having the depending sides 19 thereon, These sides 19 constitute a housing for the

lock members

20 and 21 both of which are identical in shape but are loose ends of rope.

to provide a top and depending sides, the top being extended to provide eye portions for receiving the ends of a rope, an eccentric locking piece pivoted to the sides and having a circumferential groove formed therein, a depending handle on said locking piece, and a retaining screw adjustably carried in one of the'sides and arranged forholding the locking piece in jamming engagement with the p a i In testimony whereof I 'afiix my signature.

their locked position, I have provided there- I a taining screws 25 which are similar to the retaining screw 14 shownin connection with Figures 1 and 2. g

It is quite evident that the ends of the top 18 are extended as at 26 and are provided with the openings 27'whereby rope guiding eyes are provided through which the rope 28 passes, the ends of the rope being caught between the

lock pieces

20 and 21 and the top 18 of the holder and in this position being so securely held that thevpulling apart of the rope from the lock is positively prevented. It is quite evident, therefore, that I have provided a rope lock, which may be used in a pulley line so that one end of the line may be adjusted relatively to the lock without danger of the line pulling apart;

It is quite evident also that I have provided a rope 1001: which does away with the necessity of knotting the ends of the rope together and consequently saves time and labor in the fastening together or joining together two It is quite evident that in the form shown in Figure 3, the rope lock may be employed to GEORGE AGOBIAN. [n 5.

secure two loose ends of rope thus eliminating V the necessity of knotting one end of the rope in one of the eyes formed in the holder.

It is quite evident also thatthrough theuse of afew parts, which may be cast at small expense, I have provided a rope locking device which may be manufactured at small cost and which is efiicient andefiective in its use.

\Vhile I have illustrated and described my invention with some degree of particularity,

I realize that in practice various alterations V therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise alter:

: ingthe arrangement of the correlated parts without departing from the spirit of the invention of the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by United j States Letters Patent is zl. A rope lock comprising a holder formed to provide a top and depending sides, the top being extended to provide eye portions for receiving the ends of a rope, eccentric locking pieces pivoted in the sides and retaining members for holding said locking pieces in jammmg engagement with the rope ends.
