ROPE-CLAMP.

` To 4all who-m 'it may concern America, residing at Columbus, in the county ofFranklin and State of--Oh1o, havey invented certain new and useful Improve-l V tion so that it may be of the principles of SAMUEL ELNo Goon- Be it known that I, l

the United States of FnLLow, a citizen of ments in Rope-Clamps, of 'which the following is a specification. y

The present invention relates to improvements in rope'clamps, and while it is designed especially for use in connection with clothes lines, it will of course be understood that the device is equally applicable for other purposes.

The primary object of the invention is the provision of a device that is facile-in operaapplied to or detached from a rope, that 1s simple and coinpact in construction, and is comparatively ineXpensive in production.

With these. objects in consists in certain novel combinations and arrangements 'of parts, essentially three in number, whereby the clamp is produced as will hereinafter appear. b

In the accompanying drawings I have illustrated two= complete examples of the physical *embodiment of my invention constructdaccording to the best modes I have so far' devised my inventlon. In the drawings: duplex clamp made'according to my invention. ,Fig 2 is a top plan view of Fig. 1. Fig. 3 is a transverse vertical sectional view taken on either lines A-A in Fig. 1. Fig. 4: illustrates a single clamp, of which Fig. `5 is a top plan view and Fig. 6 a side elevation. Fig. 7 is a top plan view of a modified form of the single clamp.

As before stated the device, which is the subject of the invention comprises essenl tiallythree elements vor members, vor at the most, four elements are essential to complete the clamp in either one illustrated.

Referring particularly. to the duplex clamp of Figs. 1, 2 and 3, it will be seen thatl this device includes a pair of lduplicate or complementary clamp plates 1 and 2 formed with guide posts 1a and 2a, and open end slots 3. The plates may be of casty or stamped metal as desired, and as willl be apparent from the drawings the posts 1a and 2a are bent at right angles to the body of their respective plates at the ends, and these posts Specification of Letters Patent.

fit neatly intheslots 3 yat quickly and easily pose' and this ring view the invention aDdleO for the practical application Figure 1 illustrates a or both of the forms plates opposite to the"` Strengthening or reinforcing ribs 4: 4 eX- tend along the longitudinal outer edges of the plates, and in cross section, the body of l PatentedJ an. 4, A1916.

the ends of ythe l integral posts..

the plates, 'or rather the body of each plate'4 is fashioned with an irregular surface as 5, for the purpose of providing a firmer grip 'on the rope than would otherwise be the case.

The two vclamp nected by means l provided with right hand threads 7 and left plates are -directly conof a screw bar which 1s hand threads 8, and the plates are centrallyv i perforated and threaded to receive these screw threads, an annular flange or boss 9 being employed to furnish additional engagement of the threaded parts. A ring or lo'oplO is connected to the end of the screw bar, the latter beingperforated for the purr hand grasp to be used for turning the screw bar, but performs the additional function of a suspending ring for the rope to which the. clamp is attached, as will be described. v

In the form of the invention illustrated in the remaining figures of the drawing a single clamp is exemplified. Here theclamp plate 11 has an angular post or tongue 12, and the plate tongue and slot co-acting as in the other form. The screw bar 15 also performs the same function as the first bar and has the right hand and left hand threads 16 and 17 respectively and a suspending ring 18.-v In the modied form of the single clamp illustrated in Fig. 7 the plate 13b is formed with a slot 3b located near the end of the plate but not open as in the other forms. The .post or tongue 2b fits neatly and is ided in themodied construction is vsuperior to the forms shown with open slots, as it labsolutely eliminates the possibility of disenserves not only asai.

13 has the open slot 14, the

this slot, and in some instances gagement of parts while the post is in the slot.

-The screw than the posts or tongues 1a, 2b and 2a or 12, so that by turning the screw bar the plates may be separated and the tongues disengaged from their slots, as in Fig. 6. When in this osition the an ang e to each ot er and the clamp may be attached to al rope by locating the rope between a tongue'and the screw bar. The

plates are then turned to parallelism with barv is purposely made longer lplates may be turned at the tongues alining with their slots, and the bar may be turned clock-wise so that the threaded engagement causes the plates to clamp on` the rope, and in this manner the device is fixed to the rope.

The duplex clamp isespecially adapted for clamping two ends of rope or cable or the likel together, for looping or shortening, or binding' two parallel strands of rope together, and for many other purposes in connection with awnings, tackle, tents, etc., where ropes are to be attached.

rllhe single clamp is wellvfitted for use, one for instance at the ends of a clothes 7 line, and when so attached, the4 line is suspended by hanging the ring 18 over a nail or hook permanently fixed in place. rlhus the line may be put up or taken down quickly and with little labor,knotting of the rope is eliminated, and the undesirable wrapping of the rope around sharp edges or corners or other projectionsis avoided, thus prolonging the utility and longevity of the rope. The clamp may be slid along the rope to proper or desired position (after irst in presence of two witnesses.

having been loosened) andjxed in adjusted position intermediate the ends of the rope, and the comparatively small size of the clamp makes it so that the clamp will remain on the clothes line and b e wound up iaeaeae therewith Without producing an unsightly lor inconvenient protuberance.

llt will be evident that a heavy duty clamp 'may be made involving these same principles to be used in hauling cables through having anend opening for said tongue forming guiding means for holding the plates in parallelism.

2. rlhe combination with a pair of co-acting clamp plates having threaded openings and each formed with an end slot and a tongue in engagement, of a screw bar having right and left hand threads engaged in said threaded openings.
