BY ATTORNE Patented Nov. 8, 1938 PATENT o-EETCE CLEA'VER Marshall Thomas Joseph Garlinger, Sanr Jose, Calif.

Application June 13, 1936, Serial No. 85,088V

Renewed' July 18,` 1938 14 Claims.

The present` invention relates to improvements in cleavers or subsoil plows and its principal object is to provide a cleaver for use in connection with cable laying apparatus and constructed in 5' suchl a manner as to perform its function with the greatest efficiency while at the same time being easily accessible for repair and exchange purposes.

The present application is a continuation in I0! part ofl my application Serial Number 61,387,

l'e'd January 29th, 1936, ona Machine for layingl cable, pipe and the like and is intended to cover the specific features of a cleaver or subsolli plow describedin said` application, together 1&2 with certain modifications thereof.

More particularly it is proposed to provide a cleaver of this character that is rugged in construction, is streamlined from fro-nt t-o rea-r solas to'ioffer little obstruction and to gradually spread 2W the ground surface for forming a crevice and in which the cable laying pipe is supported i-n such-a manner that it makes no contact with the soila-nd is completely protected from abrasion bythe soil androcks or other cutting agencies contained infthe soil.

Ay further object of the cleaver inY two parts one of which is movable relativeto the otherl so as to give easy access to a-i-blad'e -conned betweenthe two parts.

, A further object of thelinventionis to provide means for holding the movable part of the'cleaver inan'f inactiveposition so that the repair men not only have ample room for repairing, adjusting on replacing of the blade but may also perform 313i these operations in perfect safety and without any danger of the movable section' falling back into place.

A further object of the invention is to provide a structural arrangement particularlywell adapted for the purposes outlined, with braces and fastening means disposed in such a manner that the cleaver when assembled becomes a strong, compact unit capable of meeting all stressesy and strains to which an apparatus of this character is normallysubjected.

Further objects and advantages of my'invention will appear asl the specification proceeds.

The preferred form of my invention is illustrat'edr in the accompanying drawi-ng in which` Figure l' shows a vertical longitudinal section throughlmy cleaver,

Figure 2 aihorizontal section taken along line 21-2 .of Figure l,

Figure-3 aside elevation.I showing a portion of di, theeleaver inalockedlelevatedi-or inactive position,

the invention is to make Figure 4 a modification of my cleaver; and' Figure 5 a Vertical section along line 5--5- of Fig. 4.

While I have shown only the preferred form` of' my invention I` wish to have it understood that various changes or modications may be made Within the scope of the claims hereto attached without departing from the spirit of. the invention.

In its general characteristics my cleaver I is a narrow vertical body tapering to an inclined cutting edge in front and provided with a horizontal cutting edge at the bottom. It is made in two sections 2 and 3', the former being aboxlike structure with approximately parallel side walls 4 converging toward the front as at 5, an inclined rear wall 6, a bottom wear plate 1 and a front wall which is vertical in its upper por'- tion as at 8 and inclined in its lower portionv as. at 9 to form a seat for the blade I Il which is bolted thereto by the bolt II. The blade is provided with a plurality of bolt holes so that it may be advanced as the cutting edge wears off.

The inclined portion 9 isv continued through the body to the rear wall' 6 to brace the cleaver and to form a bearing for the feed pipe l2 which extends obliquely through the cleaver and terminates with a ared end at the bottom of the rear wall of the cleaver. The front wall of the section 2 has an undercut I3` over the inclined portion 9 to receive the rear end of the blade lll- The purpose of the feed pipe is explained in the parent application. Suffice it to say, in this connection, that it serves the general purpose of feeding a cable or the like into the ground at the rear of the cleaver so that the cable`v occupies a position in the bottom of the crevice madebythe advancing cleaver.

The section 3 forms the front of the cleaver. It has an inclined front edge formed with a groove adapted to receive the root-cutter I4 which is held in place by rivets I5. It is plvoted'f on the pin IG which latter is supported in a flange or bar I1 depending from the feed pipe l2 and section 2 of the cleaver, and when ini active position its bottomedge rests on the blade I0. It is firmly heldin place by an eye bolt I pivoted to the pin I9 extending transverselythrough this section and bolted to a cross-rib 20 provided in the bottom of the rst section 2. Blade I0 is further clamped in place by the wedging action of section 3. The inclined seat 8 and the blade aresuitably apertured as at 2I to allow the bolt to move when the front section is swung upwardvon itspivot l0'. The flange |51? isf pro-g vided with an aperture 22 below the pivot I6 so that when the front section is swung upward, a bolt 22 may be inserted through the aperture as shown in Figure 3 for holding the front section in raised position. Any other suitable locking arrangement may be substituted for the means here described.

The rear wall of the front section 3 is grooved as shown at 23 to t over a tongue 24 projecting from the vertical iront face of the main body section 2, whereby the two sections are auto-V matically brought into alinement when the front section is dropped back into active position.

It will be noted that in this manner the front section, upon loosening of the eye bolt I8, either at the bottom or at the eye, may be swung upward and locked in raised position so as to give ready and easy access to the blade l for adjustment, repair or substitution of a new blade. Since the front section 3 is subjected to considerable wear, the entire section, as well as the root-cutter blade I4, may also be easily removed, repaired or replaced. This will increase the operating eiliciency and economy of the entire machine.

A supporting post 25 rises from the cleaver and is used for supporting the cleaver relative to a vehicle described in the parent application.

A groove 26 i'lts the flat sides of the bolt head Il. The groove prevents the bolt from turning when the nut is tightened and also helps to brace the front sections 3 when wedged tightly against the blade lll). The wedging action of the front section is obtained by the angular position of bolt I8 with respect to the corner of front section 3 f through which the bolt extends.

It is understood that instead of bolt Il holding blade l0 in place, the same result can be accomplished by the placing of transverse teeth 2T and a longitudinal key or spline 28 on the lower face of blade l0 and corresponding transverse teeth 29 and a keyway 30 on the upper inclined face of section 2, the above mentioned wedging and clamping action of the front section 3 thus holding blade I0 iirmly in place. To allow for Wear of blade l0, it is merely necessary to loosen the nut on the eye bolt I8 and to advance the blade to the desired position. The nut on the eye bolt is then tightened. 'I'his is a valuable time saving and safety element of my invention.

While shown as a bolt and described as a bolt or teeth and key for holding blade I D in place, it is understood that this is for purposes of illustration only and that any suitable means may be provided for holding the blade I8 in place.
