CABLE GUIDE FOR CABLE LAYERS Filed NOV. 2, 1950 wnnn, s

In ver/tor Patented Aug. 25,n 1953 IQ,futur-ED STATE si-.PATENT OFFICE 1 Claim. 1

This invention relates to new and useful improvements in cable laying devices and the primary object of the present invention is to pro- Vide a device for plowing in cable, including a cable guide tu-be composed of hingedly mounted complemental sections that are movable relative to each other to receive or release a cable or the like.

Another important object of the present invention is to provide an underground cable layer including a vertical plate having a rear trailing Y edge to which the complemental guide tube sections are hinged and a forward edge that is fixed to a blade having the function of producing a cut Y through which the plate and guide tube will be pulled.

A still further aim of the present invention'is to provide an underground cable layer that is simple and practical in construction, strong and reliable in use, ecient and durable in operation, inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view of the invention in a ditch;

Figure 2 is a plan view of Figure 1;

Figure 3 is an enlarged detail sectional view taken substantially on the plane of section line 3-3 of Figure 1;

Figure 4 is an enlarged detail vertical sectional view taken substantially on the plane of section line 4-4 of Figure 1;

Figure 5 is an enlarged detail horizontal sectional view taken substantially on the plane of section line 5-5fof Figure 1;

Figure 6 is an enlarged detail vertical sectional view taken substantially on the plane of section line 6-6 of Figure 2; and

Figure 7 is a fragmentary perspective view showing the skid spaced from the cutter.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral I6 represents a vertical plate having a straight forward vertical edge I2 and a concave rear edge I 4.

A flat elongated slide plate or skid I6 is fixed by welding or the like to the lower edgeA of the plate I0 and includes a forward end I8 that projects laterally forward from the edge I2. A downwardly and forwardly tapering plow point or Wedge 20 is xed by welding or the like to the upper face of the end I8 and its rear vertical face abuts a pair of spaced parallel blocks 22 that are fixed by welding or the like to the upper face of the skid I6.

A pair of tube-forming channels 24 are secured to the rear edge I4 by a suitable number of hinges 26 to permit movement of the channels 24 toward and away from each other. Pairs of ears 28 are secured to the channels 24 and these ears 28 are joined by fasteners 30 to retain the channels 24 in the form of a guide tube. The lower downwardly and rearwardly curved ends of the channels 24 rest upon the rear end of the skid I6 and the upper ends of the channels 24 are outwardly flared to provide entrance guides 32.

The rear vertical edge of a metallic strip 34 is secured against the forward edge I2 of the plate Ill by a fastener 36 that extends through the strip 34 and a pair of spaced straps 38 between which the strip 34 is received. The straps 38 are xed by welding or the like to the side faces of the plate I0 and project forwardly from the edge I2.

A pair of wings 40 are welded to the lower portion of the strip 34 and taper toward the beveled forward edge of the plate or strip 34 to form a cutter `C whose lower end seats upon the blocks 22 and with the lower forward corner 42 of the plate I0 positioned between the blocks 22.

The rear ends of a pair of back-to-back channel members 44 are secured against the side faces of the plate I0 by bolts 46 and support a boxlike member 48 to the upper wall of which there is fixed a plate 50, A transverse sleeve 52 is detachably secured to the plate 50 and the upper wall of member 48 by one or more set screws 54 that will retain a horizontal pole or rod 56 in the sleeve 52 whereby the device may be guided by two operators holding the ends of the pole 56.

In practical use of the present invention, the forward ends of the beams or channel members 44 are attached to a tractor whereby the device will be pulled through a ditch D. The fasteners 30 are loosened to permit the cable `Ca to be extended through the channels 24.

As the device is pulled forwardly, the cutter C will cut through any obstruction and the plow point 20 will form a channel for the cable.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art.

A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claim.

Having described the invention, what is claimed as new is:

In combination with a cable laying plow including a vertical plate having a rear edge with an upper portion which is straight and slopes upwardly and forwardly and a lower portion which curves downwardly and rearwardly, a cable guide comprising a tube divided longitudinally in thev vertical plane of said plateto provide a pair of complementary sections having front and rear abutting edges, each of said sections having a curved lower portion disposed on said curved lower portion of said rear edge and a straight upper portion disposed on said straight upper portion of said rear edge, hinges connecting the straight upper portion of each section to the straight upper portion of said rear edge, the pivotal axes of the hinges of each section being aligned and parallel to said straight upper portion of said rear edge, registering ears on the rear abutting edges of said sections, and removable fasteners securing said ears together, whereby said sections may be swung apart to receive or release a cable or the like.
