Original application January 29, 1936, Serial No. 61,387. Divided and this. application June 13, . 1936, SerialNo. 85,087 ‘ v 1 8 Claims. (01. 280-3315) The present invention relates to'improvements in a coupling and aligning device 'andtis divisional to my application, Serial Numberv?lg38'7, filed January 29, 1936, on a Machine for laying: cable, .5. pipe and the like. In the latter application I described a cable laying out?t comprising a tractor or otherdraft means, a reel carrier and a cable laying machine adapted to draw a crevice through the earth sur face, to feed the cable into ‘the crevice, to cover the crevice over the cable andto tamp the cover age in a single and continuous operation. After a complete reel has been‘ fed into the ground in this manner it is. necessary to dis~ connect the reel carrier from. ‘the cable laying ' ’ Further objects and advantages of my inven tion will appear as the speci?cation proceeds. ' The preferred form of my invention is illus~ trated in the accompanying drawing in which , Figure 1 shows the cable laying out?t ‘in side elevation. - Figure 2 shows a top plan View, on an enlarged scale, of my coupling and, aligning means, ' Figure 3 a side elevation of the same, - _ Figure 4 a transverse section taken ‘along line 4-4 of Figure 2, and Figure 5 a transverse section taken along line 5-5 of Figure. 2. 15 ' machine, to pull the carrier‘. toward a'new reel, While I have shown only the preferred form of to exchange the old reel for _ a new one, to my‘ invention I wish to have it understood that various changes or modi?cations may be made within the scope of the claims hereto attached without departing from the spirit of the inven tion. Particularly ‘I wish to have it understood that while in the present speci?cation I have de scribed my coupling and aligning means in con manoeuvre the reel carrier back into operative proximity to the cable laying machine and tore-, couple the same. i . ‘ . . 1 " V In view of the heavy weights‘ involved and in view of the fact that in field operations ‘the ground‘ is always uneven. and difficult to work on, the re-coupling is a dif?cult task, very time-con 25 suming and accompanied by ‘ hazards for ‘ the operators. As a matter ‘of: fact, ini-presentt?eld operations, much more time is usually spent in a day's work on the re-coupling operations tha on the actual laying of the cable. I 30 means for determining the intensity of the draft required for a particular operation. , ' It is the principal object of the present inven tion to provide a coupling and‘ aligning means which allows the re-couplingkto be effected ex peditiously and without any hazards to the oper ators. - It is further proposed to provide a coupling and aligning means which is‘power-operated or otherwise and which may use'the power of the tractor or other draft means for furnishing the power required. 40 More particularly it is proposed to combine an aligning means with the coupling means. whereby the reel carrier and the cable laying machine are ?rst drawn toward one another and into align ment with one another until respective “parts 'of the reel carrier and the cable laying machine have reached, a desired relative‘position in which nection with a cable ‘laying out?t, 'the'principles of the invention are not con?ned to this particué paratus are to be coupled, particularly under difficult conditions as are found in general ?eld operations. 7 g ‘ I. I Referring to the drawing in detail it will .be noted that the cable laying out?t shown in Figure 1 consists of the tractor I; the reel carrier 2 and the cable laying machine 3. The latter'has been described in the parent application and is, only brie?y referred to herein as comprising a frame 4, a pair of wheels 5 supporting the same rela tive‘to the earth surface, a subsoil cleaver 6 ad justable relative to the frame to draw a furrow or crevice through the earth surface, a feed tube 1 for guiding the cable 8 from the reel 9 to a 40 point l0 at the rear end of the cleaver, back-?ller blades l I for covering the furrow or crevice after the'cable has been laid and a roller l2 for tamp ing the coverage for the cable. .
