UNITED STATES" PATENT OFFICE f 1 2,568,859 I f PORTABLE DERRICK CRANE Henry F. Illies, Fosston, Minn. Application September 26, 1947, Serial No. 776,256

This invention relates to a derrick crane adapted to be mounted on a small motor vehicle and while adapted generally for supporting, raising and lowering or conveying heavy objects is especially adapted to provide a support for an'-- auger such as is employed for digging post holes and by means of which the auger may be adjusta- -bly supported with respect to the vehicle, lowered gradually as it advances into the ground,

subsequently raised out of a hole dug thereby for lifting the dirt out of the hole with the auger thereby leaving a clean hole ready to receive a post or pole, and by means of which the auger may be swung through a horizontal arc relatively to the vehicle on which the derrick crane is mounted for positioning the auger at any desired location with respect thereto.

Still another object of the invention is to provide a portable derrick crane of the character previously described having an extensible jib or spar by means of which the supporting means attached to the auger or other load may be extended or retracted relatively to the derrick crane mast for positioning the auger or load at various distances or radii with respect to a given point of the vehicle to afford means whereby the auger may be employed on the opposite side of a fence,

' trench or other obstruction from the supporting vehicle of the derrick crane.

Still another object of the invention is to provide a derrick crane as previously described having driving means of relatively low horsepower -for actuating the hoisting rig for raising and lowering the auger or other thereby.

Still a further object of the invention is to provide a portable derrick crane having a novel frame structure for securely mounting it on a load supported motor vehicle and by meansof which the derrick thereof, and wherein:

Figure 1 is a perspective view of the portable derrick crane;

Figure 2 is an enlarged side elevational view of a portion thereof, and

Figure 3 is-an enlarged perspectiveview of the 1 Claim. (Cl. 212-55) bearing in which the upper end of the crane and mast is journaled.

Referring more particularly to the drawings, for the purpose of illustrating a preferred application and use of the invention, a jeep type truck is shown in Figure 1 at 5 in broken lines with the frame, designated generally 6 of the derrick crane -1 shown mounted thereon.

The frame 6 includes upright corner posts 8 which rise from the vehicle 5, adjacent the four corners thereof; the two rear upright posts 8 being secured to the rear corners of the vehicle 5 and the two forward posts 8 being secured to theends of a transverse supporting bar 9 formed of angle iron. The posts 8 are connected at their upper ends by a rectangular frame l0 formed of longitudinally extending side members and transversely extending end members which are braced to each corner post by diagonal braces H. The frame 6 also includes longitudinally extending side members I 2 which join at their ends with the lower ends of the corner posts 8 located at corresponding sides of the ehicle 5. The frame 6 also includes upright side posts l3 located intermediate of the ends of the frame and which are connected to the longitudinal side members I! and the side members of the frame portion I0, located thereabove and which are likewise braced relatively to the frame portion I I) by additional diagotively to said platform 'I 6 by diagonal brace mem- "bersl9.

The platform It supports an upwardly opening socket 20 in which is 'swivelly supported the lower end of a substantially uprightmast 2|, form- 'ing a part of the derrick crane 1 and which is journalled near its upper endin a bearing br naled in a cap 24which, as best seen in Figure' 3,

is provided with two pairs of ears 25 which project radially from the periphery thereof for receiving between each pair-orsaid" ears-the re.-

gearbox. nally atone end thereoftothe-brace 34.-and has stricted end 26 of a brace rod 21. The ends 26 are fastened between the ears 25 by fastenings 26 and said pairs of ears are spaced from one another so that the tie rods 21 can extend downwardly and forwardly therefrom in diverging relationship to be secured at their forward ends to the two front and upper corners of the frame 6, as clearly illustrated in Figure 1.

As best illustrated in Figure 2, the derrick crane I has a'boom, designated generally 29' projecting substantially at right angles'from' adjacent the upper end thereof. The boom 29 includes an inner tubular section 30 the inner end of which is formed integral with or suitably rsecured-to the mast 2| and the opposite, outer end of which telescopically receives the other section-'"3lioffthe boom 29 which protrudes beyond theouterend of the section 36 and which'is provided, adjacent able elevation and has a pair of sleeve members 59, forming a part thereof and which are mounted for swivel movement with respect to the clamp 58 and in each of which is clamped an elongated guide tube 60. The two guide tubes 60 support a pair of rods 6| which are reciprocably mounted therein and which are provided, at corresponding ends thereof with out-turned portions 62 carrying clamps 63 at the terminal thereof which are secured to the ends of the arms 51. The guidetubes 60 extend rearwardly across one side of the brace 34 and are guided for swinging movement relatively thereto by a rod 64 which its outer end, with a depending bifurcated-hanger 52 in which is journaled a pulley 33. The boom e26 is braced relatively to the mast-2|wbya brace 34, the lower end of which is=fixed-to-or formed said section 30. Thebrace-fl is reinforced-relatively to'the mast 2 l by a; brace 35 and additional bracesmay beprovided, if required. A-chain or flexible member 36 is attached to the brace -34,

. adjacent the upper end of the latter, and F has a :pin 31: attached to its -freeend for selective engagement in longitudinally spaced openings '38 of thcrboom section-3|, fora-purpose which will hereinafter becomeapparent.

A platform .39 is supported between and. on

' themast 2l-andabrace34 for mounting al-motor 44, preferably a-small electric motor having a H driven shaft 4| provided -with a-tpulley 42. second platform 43. is: supported by 'themasti l,

below and toone side. of theplatform-N'for supporting a-gearbox 44 containing reductionrgearing, not shown, and having-arshaft fi project- 42 and -46- for driving -.the shaft 45 f-romwthe shaft 4| and,-.as seenin Figure 1,-a shaf t. 48,projects fromthe gear box flkatright anglesto'the isdisposedparallel to the brace 34 and spaced therefrom by spacing members 65 which connect the rod-'64, adjacent its ends, to the brace 34.

It will be-readily-apparent from the preceding descriptionthat the weight of the auger 56 on thecable 54 will tend to cause the boom section 3| to telescope into the boom section 30 so that the pin 31 'willfun'ction'to retain the 'boomsec- "tion 3| in an extendedposition, variable dependauger motor and z-also the motor 40. In order ing from one side thereofand carrying a (pulley-c 46. An endless belt 41-isetrainedover the pulleys shaft and 'isdriventherebyat a reduced-speed by the reduction :gearing contained within. said A vbracket 49 fastened-longitudian upper, .outwardlyoff-set .end .formingrar :bearto extend the boom 29, the cable 54 can be slacked off to allow the auger 56 to cometo .rest on theground'and by providing additional slack in 'the-cab1e-54'the boom section '3l may be readily extended. The auger 56 ismanually guided in drilling a hole in-theearth: and as the auger penetrates-the earth the cable 54 is slacked off. When a hole of the-.desireddepth hasbeen drilled, I the motor 40 is energized 'for revolving the drum or 5 shaftw56 for rewinding' the cable '54 thereon to thereby extract theauger 56 from the drilled 'hole and r at the "same time extract 1 the loose dirt' with the auger leaving-a clean hole in which-a post or p'ole maybe inserted.

When the auger-=56 is raisedand'l'owered the -guide-tubes60 and clamps--59 willswing relatively to the clamp 58 'and'mast 2|, and therods 6| will slide within said guidetubes 60. ".By extending theboom 29 for-positioning thea'uger 56 at a'greaterdistance from the mast '2! and the rearend of the vehicle 5,-it-will'bereadily apparent that the augermay be utilized-onrone ing for one end of a shaft or drum.'5I,--the-OPP -a 55 site endofwhich-is journaled inthebrace34. A pulley 5l is keyed to thershaftor-drum-jfl adjacent its last mentioned .endto be driven by the :shaft 48 by means ofan endless-belt52- which i trained-overthe pulley5l and overarpulley .53 keyed to the shaft- 48 so that .the 4 shaft or drum 5!! will be driven at a reduced speed: shaft 4| of. the motor 40.

A cable or other suitableflexible hoistingmemby the side of an obstruction and-while the vehicle I is disposed on the opposite side thereof under "circumstances where said vehicle 'camiot be moved across theobstruction. Likewise, the mast'll may rotate in-its journals'20, "22 and 24 "for swinging the entire-derrick crane 1 -tln'ough="an arc of approxi'niately180 and sothat the auger 56 may be utilized at anyposition withinsaid arcand at various radii relatively to the mast thus accommodating the derrick crane l for'use at positions which might otherwise be inaccessible to the vehicle 5. When the derrick crane "I is not in use theguide tubes Gil-may be moved inwardly of the clamping sleeves 56.and the auger v56 may be swung toward and secured etowthe brace 34 to facilitate transportation-thereof. wIt :will be readily apparent that-the tie-rodsflwill assist materially in supporting theweightzof the auger '56.

The frame 6 and majority of-the.derricklparts 1 may be formed-oftubularrmetali as illustrated in Figure 3, or said parts may be of solid construction.

While the portable derrick crane has been described in connection 'With the handling of an auger, constituting a preferred utilization there- .of, it will be readily apparent that any other load may be substituted for the auger 56.

Various other modifications and changes are likewise contemplated and may obviously be resorted to, without departing from the spirit or scope of the invention as hereinafter defined by the appended claim.

I claim as my invention:

A portable derrick crane comprising a mast supporting frame adapted to be secured to the sides and ends of a motor vehicle and supported thereby, an upright mast swivelly supported on the frame beyond one end of the motor vehicle, an extensible boom projecting outwardly from the upper portion of the mast and disposed in a horizontal plane, said boom comprising an inner section rigidly secured to the mast and an outer extensible section telescoping into said inner section through the outer end of the inner boom section, said outer extensible section being provided with a plurality of longitudinally spaced openings, a pulley journaled on said outer extensible section adjacent its outer end and outwardly of the inner boom section, a driven winding drum supported by the mast, a flexible member having one end secured to and wound on the drum and extending from said drum over the pulley and terminating in a depending load is supportin a load.
