LINE-G RIP.
SPECIFICATION forming part of Letters Patent No. 577,735, dated February 23, 1897.
I Application filed May 18, 1896. Serial No. 591,971. (No model.)
T0 (1, whom it may concern:
Be it known that I, JAMES P. FEeAN,of Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Line-Grips, of
which the following is a specification.
This invention relates to clamps for adjustably holding the ends of lines, such as clotheslines, and has particular reference to that type of such devices in which a lever is formed to clamp the line between itself and a suitable base, the clamping tension of said lever being preserved by the strain of the suspended line or rope.
The object of this invention is to produce a simple, practical, durable, and efficient clamp of this type; and to this end the invention consists in the construction and combination of parts, substantially as hereinafter described and claimed.
In the drawings, Figure 1 represents a perspective view' of a clamp embodying my invention. Fig. 2 represents a similar view from another point and illustrating a diiferent and preferred form of the lower end of the lever. Fig. 3 represents a side elevation of the lever shown in Fig. 2.
Similar reference-characters indicate the same parts throughout the several views.
a represents a base-plate having suitable holes a to adapt it to be attached to a wall, post, or other means of support. This plate is provided with a boss or lug b, which is preferably cast integral with the base-plate, said boss being provided with a pin 0, preferably an integral one, provided with a head a, said pin forming the fulcrum for the lever presently described.
d indicates the lever, having its upper end bifurcated to form two horns d and provided near its mid-length with two pairs of lugs e, which are bent or crimped so as to surround or partially surround the pin 0. This construction provides an easy means for uniting the two parts of the clamp and a durable means for holding them in operative correlation. Below the axial point the lever is pro vided with a cam-shaped projection f at its rear, which is adapted to clamp the end of the rope or line.
The lower end of the lever shown in Fig. 1 is bifurcated to form two curved horns g, between and around which the lower end of the rope or line may be carried or twisted, while in Figs. 2 and 3 I show the lower end of the lever as provided with a single corkscrew-finger or a spirally-curved hook It.
In the operation of the device the line or rope to be clamped is passed behind the lever and under the pin 0 and led over and between the horns cl at the upper end of the lever. The lower end of the rope passes down be tween the cam f and the base-plate and may be drawn so as to pull the horizontal portion of the line taut, when the tension or strain on said horizontal portion will increase the binding action of the cam f against the line or rope and hold it firmly against the base-plate. For additional security the lower portion of the rope may be carried around the horns g, (shown in Fig. 1,) but I find the form of the corkscrew-finger or spirally-shaped hook h a preferable one in that the rope can be simply carried over said hook, when the weight of the rope acting on the said hook increases the binding action of the clamp.
The lever is arranged between the pin and the plate, in such Way that the body of the lever bears against the pin, and so that the for wardly-extending lugs e e do not have to withstand any strain that would tend to straighten them, since they operate merely to hold the lever in the proper position on the pin.
I claim- 1. A line-clamp comprising in its construction a base-plate having a lug I) provided with a pin 0 projecting from one side thereof, said pin being provided with a head, and a lever d inserted between the pin and the base-plate so as to bear against the pin, said pin being provided With a bifurcated upper end, a corkscrew-finger at its lower end, and with a cam portion coactin g with the base-plate, said 1ever also having forwardly-extending lugs e bent around the pin c whereby the strain upon the lever is borne by the pin, and not by the lugs, said lugs coacting with the pin and the head thereof to retain the lever in position, substantially as described.
2. A line-clamp comprising in its construcpin and the head thereof to retain the lever in position, substantially as described.
In testimony whereof I have signed my name to this specification, in the presence of I 5 two subscribing Witnesses, this 12th day of May, A. D. 1896.
JAMES P. FEGAN.
