CIibTHESLINE-GLAMP.

Specification of Letters Patent.

Patented July 26, 1921.

Application filed November 4, 1918. Serial No. 260,958.

T 0 aZZ w 7mm it may concern: Be it known that I, HERMAN KrsTNnR, a citizen of the United States, residing in the city of Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Clothesline-Clamps, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it pertains to make, construct, and use the same, reference being had to the accompanying drawings, and to numerals of reference marked thereon, forming a part of this specification.

This invention relates to a clothes-line clamp adapted to clamp lines of different thicknesses, cables, belts, wires or the like, to permit the same to be readily released or put in a gripping position.

The object of my invention is the production of a clamp which shall be simple in construction, efficient in operation, and comparatively inexpensive in cost.

With this end in view, my invention consists in certain novelties of construction and arrangements of parts as hereinafter set forth and pointed out in the claim. lVhile the preferred form of my invention is illustrated in the accompanying drawings, yet it is to be understood that minor changes may be made without departing from the scope thereof.

In the drawings,

Figure 1 represents a front elevation of my improved device.

Fig. 2 represents a vertical section of the same, and

Fig. 3 represents a transverse section taken on line m-m of Fig. 2, looking in the direction indicated by the arrow.

In the drawings, 1 represents a casing made of cast iron or other suitable material, of any desired or convenient shape, provided in its lower portion with an angular bore 2, open from end to end. Communicating with the angular bore 2 and extending in an upward direction, approximately near the center thereof, is a guide-way 3 provided with a contracted portion 4: and an enlarged portion 5, the contracted portion of which receives the eccentric grip 6, and the enlarged portion 5 receiving the handle 7 of the eccentric grip which is adapted to extend outside of the casing 1. The ends 8 and 9 of the enlarged portion 5 provide convenient stops to limit the movement of the eccentric grip handle 7 in either direction. The casing, at one end thereof, is provided with, preferably, an aperture 10 by means of which the device may be suitably attached, suspended or secured to a rope or the like. The eccentric grip 6, as clearly indicated in the drawings, is mounted upon a stud 0r spindle 11 that passes through the casing 1. The peripheral surface of the eccentric grip 6 is grooved or made concaved, as at 12, for the reception of the line 13, and said grooved or concaved portion is further provided with corrugations or teeth 14.

It will be seen that as the rope passes through the bore 2 and between the concaved and toothed surface of the eccentric grip 6, that if it is pulled in the direction of the arrow at no resistance will be offered by said grip, and it can be drawn upon as much as desired; but when drawn in the direction of the arrow 6 the grooved or cor rugated portions of said grip press upon the upper portion of the rope, so that the more strain applied the greater will be the grip upon the rope, when the handle is in the po sition illustrated in Fig. 2 of the drawings.

When it is desired to release the rope, the handle 7 is raised to'the position shown in Fig. 1, and the rope is free to be drawn out. The particular construction of the gripping portion of the grip 6 enables articles to be gripped or held and quickly and readily released without abradlng or destroying its tensile value. The construction of the bore 2, as noted in the drawings, is provided with an angular portion 15, which of itself will, in a measure, act as a grip and has been found in practice to be more efficient than a straight bore.

It will be understood that in practice modifications of the specific structure shown may be made, and any suitable material and proportions may be used for the parts without departing from the spirit of the invention.

What I claim is A clothes line clamp consisting of a solid body having an angular and tubular bore through it, a guide-way provided with a con tracted and an enlarged portion communieating With said bore, and an eccentric grip of the clamp, whereby it may be suitably atpivoted therein, said guide-Way and eccentached or suspended. f 10 tric grip being of less Width than the said This specification signed and witnessed angular bore said eccentric grip being prothis 24th day Of b 1918- Vided in its periphery with a grooved por- 'HERMAN KISTNER. tion provided With corrugations means for Witnesses: engaging and releasing the same from a FREDK C.
