Description

Jan. 18, 1944. c. R. BERGMAN CABLE PULLER' Filed Aug. 20, 1945 Patented Jan. 18, 1944 UNITED STATES FATENT QFFICE CABLE FULLER Carl R. Bergman, Minocqua, Wis.
Application August 20, 1943, Serial No. 499,400
3 Claims.
This invention relates to a puller for use by electricians or their helpers in pulling stranded wire or cable or conductors through conduits.
It is particularly aimed to provide a means which readily and expeditiously may be placed on the cable, may be used by inexperienced workmen, which will yield and adapt itself to inequalities within conduits, and which in many instances will enable replacing and positioning the cable in the conduits through pushing by one man.
In addition it is aimed to provide a novel structure generally of bullet shape made of a yieldable plastic material and preferably having reinforced openings therein to enable pins or the like to be driven into a socket thereof which receives the cable.
The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawing illustrating an operative embodiment.
In said drawing:
Figure 1 is a view in elevation showing my improvements in place on a fragment of a con ductor cable;
Figure 2 is an enlarged central vertical sectional view through the puller;
Figure 3 is an end view of the puller; and
Figure 4 is a horizontal section taken on the line 44 of Figure 1.
Referring specifically to the drawing wherein like reference characters designate like or similar parts, I provide a puller generally in the form of a socket or tube at ID, for the most part made in one piece, preferably from any suitable plastic material so that it will be slightly yielding or elastic in order to yield and give in passage through conduits. Such sleeve or body If! is open at one end into a socket ll into which a stranded cable or any equivalent I2 is adapted to be inserted. The present invention accommodates such cable without the necessity of cutting away any of the insulation, and hence it is readily applicable into the socket. At suitable intervals metallic eyelets or reinforcements I3 are embedded in the wall of the plastic, forming openings 14 through which pins l5 are adapted to be driven. Such pins, as shown in Figures 1 and 4 are preferably of a length to extend completely across the bore of the socket II, and it will be noted that the eyelets I3 ar arranged in diametrically aligned pairs so that the pins l5 will at opposite ends be disposed in openings 14 of the eyelets. These pins pass through the metallic strands l6 of the cable, spreading them where necessary, as shown in Figure 4. Preferably a pair of pins I5 are used since they make a crossed arrangement giving maximum strength, arranging each of the pins so that it cannot be pulled loose at either end. The pins l5 preferably are screws as shown although any equivalent may be used.
, One end of the body or sleeve I0 is closed as at I? but may be open in part, but such end in any event will be generally conical or bulletshaped or the equivalent to facilitate its passage with such end I! foremost in the conduit. Such end has an eyelet or metallic tube It embedded therein, forming an opening at l9 whereby a rope or the like may be attached for the purpose of pulling the puller and cable through the conduit.
As a result of the construction, a very effective hold on the cable is provided by the socket in combination with a pinal pin l5, and the structure readily may be pulled with the end I! foremost through a conduit, and since it is made of plastic material, it will yield, spring, or give according to inequalities within the conduit, greatly facilitating the drawing of the -cable. The
puller may be applied instantly and operated by unskilled labor, and in instances I have found that often the cable I2 may be pushed in place by one man, with the puller in place thereon, it being unnecessary in such instances to use the rope or other draw element at the eyelet l9. Also in such instances the yielding, giving. .or flexibility of the plastic puller I0 is of great advantage.
Various changes may be resorted to provided that they fall within the spirit and scope of the invention. I
I claim as my invention:
1. A device of the class described for application to cable to aid'in the positioning thereof in a conduit, the device comprising a tubeof yielding material having a socket or attachment to the cable, said tubing being closed at one end, and at that end being generally of bullet shape, said body having an opening therethrough to enable a pin to be passed through the cable to anchor the latter to the body, said body also havin an opening in diametric alignment with said opening so that the pin at its entering end may extend into the same.
2. A device of the class described for application to cable to aid in the positioning thereof in a conduit, the device comprising a tube of yielding material having a socket or attachment to the cable, said tubing being closed at one end, and at that end being generally of bullet shape, said body having an opening therethrough to enable a pin to be passed through the cable to anchor the latter to the body, said body also having an opening in diametric alignment with said opening so that the pin at its entering end may extend into the same, said body also hav ing aligned openings and a pin passing through the latter openings in crossed relation to the first-mentioned pin to anchor a cable.
3. A device of the class described for application to cable to aid in the positioning thereof in a conduit, the device comprising a tube of yielding material having a socket or attachement to the cable, said tubing being closed at one end, and at that end being generally of bullet shape, said body having an opening therethrough to enable a pin to be passed through the cable to anchor the latter to the body, said body also having an opening in diametric alignment with said first opening so that the pin at its entering and may extend into the same, said body also having aligned openings and a pin passing through the latter openings in crossed relation to the first-mentioned pin to anchor a cable, and eyelets in said openings reinforcing the same.
