CLOTHESLINE FASTENER Filed March 1'7, 1958 Patented June 6, 1939 UNITED STATES PATENT OFFICE CLOTHE SLINE FASTENER Application March 17, 1938, Serial No. 196,382
My invention provides an extremely simple and highly eicient clothesline fastener and, generally stated, the invention consists of the novel devices, combinations of devices and arrangement of parts hereinafter described and defined in the claims. The device, although primarily designed as a clothesline fastener or anchoring device, is, nevertheless, capable oi general use for fastening or anchoring the end or ends of ropes, cables and the like.
The device is of such character that it will very securely anchor a rope or line against pulling strain in one direction but will yield under pulling strain in the opposite direction to tighten the line. The device includes a spring or yieldingly pressed gripping lever that automatically sets to prevent slack pulling movement on the line. The body of the device is an L-shaped structure, preferably a metal casting, provided 20 with an approximately L-shaped guide channel that is open at one side for the application of or removal of the line from the body member. The
clamping `lever has an extended portion that is spaced from but in such close parallel arranged ment to the main arm of the L-shaped body that the complete device may be gripped by one hand and used to release the biting action of the lever on the line.
The above and other features will appear in the description of the commercial form of the device illustrated in the accompanying drawing wherein like characters indicate like parts throughout the several views.
Referring to the drawing: 35 Fig. 1 isa side elevation. showing the improved device applied to one end of the clothesline or the like and anchored to a suitable support;
Fig. 2 is a section taken on the line 2 2 of Fig. 1; 40 Fig. 3 is a section taken on the line 3 3 of Fig. 1; and
Fig. 4 is a section taken on the line 4 4 of Fig. 1.
The L-shaped body is indicated as an entirety by the numeral 5. This body 5 is formed with a relatively long or main arm 5a and a relatively short or depending arm 5b, the extreme lower end of which arm 5b, as will presently appear, affords a clamping abutment 5c. The body 5 is formed with an approximately L-shaped guide channel 6 that extends through the arms 5a and 5b and is open at one side for the lateral application of the rope to the channel or the removal of the rope therefrom, without requiring the rope 55 to be threaded through the channel. On its lower (Cl. 18S-65.1)
or `inner flange the channel 6 is formed with retaining flanges 'I and 8 which keep the rope against lateral displacement when under tension. These flanges 'I and 8 are so spaced from the outer walls of the channel that the rope when slightly kinked may be entered into or removed from the channel. The flange 8, it will be noted, is at the elbow of the channel, while the flange 'I is in the long horizontally extended portion of the channel.
To increase the grip on the rope, the jaw or abutment 5c is preferably formed with a pocket or depression 5.
Projecting from the arm 5a is a ange 9 shown as formed with an eye I0 to which is applied a link Il that is adapted to be detachably secured to an anchoring hook I2 or the like secured to a suitable support I 3, such as a post or wall. The body member 5 in its re-entered angle is provided with a hinge flange or lug I4 to which a clamping lever I5 is pivotally connected by a pin or rivet The short arm of this lever I5 terminates in a clamping jaw I'I that is opposed to and cooperates with the abutment 5c to grip and tightly hold the clothesline, rope or cable y. This jaw l1 is preferably grooved, as best shown in Fig. 3, to hold the clothesline or rope against lateral displacement and to give increased grip on the rope. The long arm of the lever I5 is extended below the long or upper arm 5a of the L-shaped body, in such near parallelism to the latter that the device may be gripped by one hand, preferably the left hand as shown by dotted lines in Fig. l. A coiled spring I8 is interposed between the long arm of lever I5 and the long or upper arm 5a of the L-shaped body and puts the clamping lever under strain to grip and hold the rope or line. v
Fig. 1 shows the device applied to hold one end of a clothesline or the like, the opposite end of which may be anchored by another device, such as shown in Fig. l, or may be simply tied or otherwise secured to any distant support. With the device applied as shown in Fig. 1, it is evident that the operator with the right hand, by pulling clown on the depending end of the line, may put the line under increased tension. By a real hard downward pull on the line this tightening of the line may be accomplishd without releasing the clamping lever. However, to make the pulling action easy, the lever should be released from the line; and this may be easily done with the left hand applied as shown by dotted lines in Fig. 1 and while the depending end of the line is being pulled downward with the right hand.
When the line is under tension and it is desired to give slack to the line, the lever, by the application of the hand as illustrated in Fig. 1, presses the long end of the lever upward, thereby entirely releasing the bite or gripping action of the jaw I1 on the line. This releasing of the line is, of course, necessary as an initial step in taking down the line.
When it is desired to take the line down, it may be quickly detached from the fastening device simply by giving the line slack and then moving the line laterally out of the channel; and, of course, the line may be applied in the channel by reverse operation.
A quite strong spring IlB is `desirable between the long end of the clamping lever and the long or upper arm of the L-shaped body and to overcome this spring requires vconsiderable pressure on the lever. This pressure is very readily and easily applied when the hand grips the body and the Vlever as shown.
A preferred commercial -form of the device has been illustrated in the drawing, vbut it Will be understood -that the same is capable of modication 4as -to details of construction and Varrangement -of parts within the scope of the invention herein disclosed and claimed.
What I claim is:
1. In a'device of the kind described, an approximately L-shaped body having a relatively long upper-and a relatively short depending arm, said .body Abeing formed with an approximately L- shaped guide channel that is open at one side throughout its L-shaped portion, the short arm of said fbody terminating ina clamping abutment,
ka'clamping lever pivoted to said body and having Aa short end acting as a clamping jaw opposed to the abutment-forming portion of said body, said lever vhaving along armspaced from but extending in such near parallelism to the long arm of said body vthat `both may -begripped bygone hand, to release said lever, and a spring compressed directly between vreacting against said clamping tension.
lever and overlying body and normally causing said lever to grip a line.
2. A device of the kind described comprising an approximately L-shaped body formed with an approximately L-shaped line guiding channel, and a spring-pressed clamping lever pivoted to said body, with the short end thereof acting as a jaw opposed to one arm of the L-shaped body, said clamping lever having a relatively long end spaced from but extended in such near parallelism of the main arm of said body that both may :be gripped by one hand to release said lever, and in Which said L-shaped channel is open at one side for the lateral application of a clothesline or the like into said guide channel, the open side of said guide channel having a retaining ange for holding the line against lateral displacement when under tension.
3. In a device of the kind described, an approximately L-'shaped body having a relatively long upper and a relatively short depending arm, said body being formed with an approximately L- shaped guide channel that is open at one side, lthe short arm of said body terminating in a clamping abutment, a clamping lever pivoted to said body and having a short end acting as a clamping jaw opposed to the abutment-forming portion of said body, said lever having a long arm spaced from but extending in such near parallelism to the long arm of said body that both may be gripped by one hand, to release said lever, and a spring, reacting against said clamping lever and body and normally causing said lever to grip a line, and in which said L-shaped channel is provided with retaining flanges, one located at the elbow bend and the other in the long upper leg of said body, said retaining flanges being spaced from the outer Walls of said channel so as to permit lateral passage of the line into and out of said channel, When said line is free from FRANK J.
