The platform I2 is removed at the middle portion of the frame to provide a well 22 in which I arrange my improved tower which is indicated The` toweris mounted upon a .truck 24 which' includes transverse channel 'members 25 and. longitudinal I-beam members 26. The members 25 and 26 are vsecured together. at their ends. `The I-beamV members `26 apertures through which tubular axle supporting members 21 are inserted. The members 21 are held in place as bywelding at 28. The tubular members 21 receive axles or shafts 29 which support roller bearings 30 which latter support wheels 3 I.
Each wheel 3| has ,a plate 32`provided with apertures 33 receiving screws 34 which enter the wheels to hold the plates in place. serves to hold the bearings plate is provided with an aperture 35 which receives a reduced portion 36 on the axle 29.
The axles 29 are received in a pair ofv plates 31. Each V'plate has a ange 31a secured to the frame II` by bolts 31h. The` plate 31 is braced bydownwardly converging angle members `31c. plate 31 has an aperture 31d reduced end portion 353 on the Vaxle 29. Washers 31e are arranged on each side of the plate 31. The wheels are held in place by pins 38 which pass through the portion 360i theshaft.
Upon each endof each of the Ifbeams 26 I secure pins 40 which are upwardly directed and are held in place as by welding at 4 I. Each of the pins slidably receives a tube l42. Thetubes 42 which receives the tubes 42 rest upon the I-beams 26 and thus their I 5a. The plates I5 I4 are free to turn thus permitting are provided with opposedl The plate 32"- 30 in place and each Each' weight is carried to 1 pair of members includes an arcuate boss 5| the wheels 3| on the truck 24. In order yto make the tower adjustable in height I employ novel coupling members which are shown in detail in Figs.
4 to 7, inclusive. Each coupling preferably includes a member 44 and a 45. A pair of the members 44 or four ofthe members 45 may be employed if 1 desired. The member 44 includes a body portion or wing 46 having a semi-cylindrical groove or recess 41 therein. Each of the members45 in#- 48 which are ar-j concludes base portions or wings ranged at right angles to each other and are nected by grooved grooves or recesses 41 and 49 are of a radius corresponding -to the external radius of the tubes 42.'
'Ihe groove 41 includes an arcuate `boss 5|) in-: and each of the grooves 49 *v intermediate Y its` the bosses 4|] andtermediate its length length. `The lower surfaces of I5| engage the top of a tube -42 upon which they are arranged and the upper surfaces ofthe bosses 50 and 5| are engaged by the lower' end of vthe upper tube'which the coupling member'supports. In use the coupling members are mounted upon a tube as-shown in Fig. 7 and suitable fastening members 52 are inserted through apertures 53 in the members k44 and 45.
YTo support the tubular members 421v provide transversely extending horizontal braces 54which are connected to the adjacent' base portions 48, as shown in Fig. '1. Above and below each horizontal brace 54 I arrange intersecting tieA mem-v bers or rods l55 which have, eyes'engaged by ,theV fastening member 52.
In order to brace 51 are secured at their upper ends to one or more sets of the coupling members bythe fastening means previously described."V The lower ends of the guy cables pass over drums 58mounted on the corner plates |5. f y i y '1 By. 'operating ycranks 59 the cables 51 may be tightened or loosened and may be heldby a pawl and ratchet device 80 associated with Yeach drum; Bytightening or loosening the cables 51 the tower kmay be readily arranged in'a vertical position regardless of the slope of the ground onwhich the apparatus rests.,V Y The uppermost set of tubes 42 supports a Ycrown blockv |55Y which comprises a rectangular frame made of channel members andhaving depending pinsj welded thereto at the corners thereof; The pins |56-, likejthe tubes'42 to prevent slipping of the crown block. The crown block includes pulleys r61 over which a cable 88 passes. 1 One end portion of the cable 68 passes" over a lower pulley `69 and onto adrum 10 'where it is drvenfthrough a clutch 1|` from a shaft 12 which is driven by a` beltV 'ory chain 13 by means of a motor 14. YThe other end of thecable 68 has a hook which engages` an eye v16 on a bail secured to a bucket 148'. The bail consists of a channel 19 as shownin Fig. 3 which, ad-V jacent to the lower ends thereof, is provided with aligned shaftsll which are pivotally supported on brackets 8| secured to the bucket by bolts 82. f
l The channels 19 receive the stems -83 lof `T- bearn guide members 84 which are removably connected to the'horizontal braces 54 by the bolts 85. The construction shown permits the 'bucket 18 to dump to the right or left in Fig. 3.V By removing the bolts 85 the T-beam guide membersmay4 be moved` through 90"V andjre-f the entirer tower, guy cablesl or recessed portions 49. The:v Y
' a drum |09where it is driven placed to permit the bucket to dump from either one of the other two sides of the tower.
The tower is shown as provided with a staging V90 which is braced by a member 9| and is held on the rods 42 by bolts 92 which pass through apertures in the rods. Y
Upon the end of the platform remote from the `motor 14 I provide a concrete mixer 93 which has a drive gear 94 driven from a gear 95 on a shaft'l96'by a'chain 91 which is driven from the sprocket -98 on a shaft 99. The shaft 99 is driven by bevel gears |00 from the shaft 12 previously mentioned by clutch means not shown.
The concrete mixerincludes a skip |95 which is vpivoted at |06 and is operated by a cable |91 |08 and extends to from the shaft 12 whichY passes over a pulley by clutch means not shown.
lInorder to move frame sides with U-shaped brackets which slidably Yreceive pipes By sliding outthe pipes they afford ready' means for shifting the apparatus.
In. order to prevent premature dumping of a bucket 18,A I provide a suitable catch |2 whichv may be released to permit to discharge the contents.
In operation the tower is the bucket to `swing `built up tothe desired heightand the bucket is arranged in the correct pins 40, fit into adjacentincluding longitudinal dumping position. The operatorjthen starts theY motor 14 l and,1 performs the various operations incident ,toV power the concrete.;` As theK work progresses the height of the tower may be changedif desired,
' From the'for'egoing description it will beapparent that I have invented a novel mobile eleva; tor, which ,can be economically manufactured andcan -be readily assembled and taken apart and which is highly efficient in use.
