Description

April 1941- w. w. WEATHERFORD 2.237.618
CJI'IOKFR KNOB Filed June 6, 1940 mlla am W Wa/iizerfird [n ventor A iiomey Patented Apr. 8, 1941 UNITED STATES PATENT QFFICE CHOKER KNOB William W. Weatherford, Arlington, Oreg. Application June 6, 1940, Serial No. 339,180
2 Claims.
This invention relates to a choker knob, the general object of the invention being to provide improved means for connecting the knob to a cable so that there is no danger of the cable pulling from the knob.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.
In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a view showing how the knob is used to hold a cable in a choker hook.
Figure 2 is a top plan view of the knob.
Figure 3 is a section on the line 33 of Figure 2.
Figure 4 is a view of the wedge member in the knob.
As shown in these views the knob includes a tubular member I and a wedge member W, the passage I through the tubular member tapers in diameter downwardly from its top to its lower end and the walls of the passage at an intermediate point is formed with an annular and rounded rib 2 and immediately under the rib with an annular rounded groove 3. At the lower part the passage is formed with a large rounded rib 4 which greatly reduces the end portion of the passage and this rib forms a flaring extremity 5 for the bottom end of the passage.
The wedge member is of substantially bulletshaped form and gradually decreases in diameter from its top to its lower end, said lower end forming a point 6 and an intermediate part of the member W is formed with the annular grooves I with rounded rib 8 between them.
The cable C has its strands separated at one end and passed upwardly through the passage of the tubular member l with such strands entirely cover ng the walls oi the passage and the member W is placed in the passage and against the nner circumference of the strands. with the point it terminating opposite intermediate portions of the large rib 4. The grooves and ribs. of the ubular member I and the member W will firmly lock the strands of the cable in position in the device. as shown in Figure 3 so that it is pract cally impossible for the cable to be pulled from the device, after the wedge member has been put in place, the large rib 4 also acting to distort the strands to further increase the wedging action and by providing a flaring lower end 5 the cable can move to a limited extent sidewise where it leaves the device.
This device can be used wherever it is desired to form a knob on the cable and Figure 1 shows one use of the device where the knob is used for holding a cable C in a choker hook H having a lateral passage in its top through which the cable part C passes.
It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.
It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claims.
Having described the invention, what is claimed as new is:
1. A knob for a cable end comprising a tubular part having a tapered passage therein, intermediate portions of the wall of the passage being formed with an annular groove and an annular rib, said rib and groove being located adjacent each other and a wedge member for fitting in a portion of the passage and wedging strands of a cable between itself and the tubular member, said wedge member having on intermediate portions of its walls annular grooves and ribs for cooperating with the rib and groove in the walls of the passage for distorting the strands of the cable and firmly grip the cable in the knob.
2. A knob for a cable end comprising a tubular part having a tapered passage therein, intermediate portions of the wall of the passage being formed with an annular groove and an annular rib, said rib and groove being placed adjacent each other and a wedge member for fitting in a portion of the passage and wedging strands of a cable between itself and the tubular member, said wedge member having on intermediate portions of its walls annular grooves and ribs for cooperating with the rib and groove in the walls of the passage for distorting the strands of the cable
