Application July 31, 1944, seria1N0.547,491 's Claims. (C1.- 18e-11), This invention relates to a mobile tower. The general object of the invention is to pro vide an improved mobile tower such as an elevator rality of pipes I4 which extend Vthrough. apertures I3 and 13a inplates I5 and I 5a. The plates I5 ' and I5a are secured to thetop and bottom of the frame I'I at each corner. thereof. The pipes I4 are provided with spaced apertures I6 through which pins‘such as bolts `I1 extend. By adjust ing the position of the pins I 1 the position of the pipes I 4 relative to the platform I I may be ad justed. Each. pipe at its lower end has a pair of or hoisting apparatus which is particularly adapted for use in elevating concrete to be poured into wall forms. l A more specific object of the invention is to provide a mobile elevator including a novel tower supporting means. l A further object of the invention is to provide 10 curved arms I8V secured thereto by bolts I9. Eachv o a novel tower construction for an elevator. pair of arms I8 supports a shaft 20 A further object of the invention is to provide whichr2I. in turnk supports a caster or transporting wheel anovel means for mounting a tower member.v . The rods I4 are free to turn„ thus permitting ' Another object of the vinvention is to provide the caster wheels to turn so that the platform may a novel joint for use in building towers and similar constructions. ` be shifted. If the apparatus isv used on a surfaceV _ that slopes, the effective’length of the rods mayr be adjusted by proper placing of the pinsr I1 so An additional object of the invention is to prou vide a novel platform frame construction for a mobile elevator.y o A that the platform vmay be heldin a substantially ` Other objects and advantages of 'my invention will be apparent from the following description horizontal position.` 20 taken in connection withthe accompanyingdraw ings, wherein: . » The platform I2 is removed at the middle por tion of the frame to provide a well 22 in which I arrange my improved tower which is indicated Fig. 1 is a side elevation of a mobile hoisting , The` toweris mounted upon a .truck 24 which' includes -transverse channel 'members 25 ~ and. apparatus embodying the features of my inven tion; _ ' , longitudinal I-beam members 26. The members Fig. 2 is a top plan View of the‘platform with the upper ends of the caster wheel pipes and the tower broken away and with the concrete mixer removed; , - 25 and 26 are vsecured together. at their ends. `The I-beamV members `26 are provided with opposedl 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 sup port roller bearings 30 which latter support Fig. 3 is an enlarged sectional view taken on line 3_3, Fig. 1,' Fig. 4 is a perspective view showing a column coupling member; ' Fig. 5 is a View similar to Fig. 4, showing an other coupling member; Fig. 6 is a fragmentary side elevation showing a column joint and column braces; Fig. 7 is a section taken cn line 1_1, Fig. 6 ; wheels 3 I. 35 ' Each wheel 3| has ,a plate 32`provided with apertures 33 receiving screws 34 which enter the wheels to hold the plates in place.

The. tubes 42 rest upon the I-beams 26 and thus their ' 2,406,335 placed to permit the bucket to dump from either ` weight is carried to 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 1 pair of members 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 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 ` or wing 46 having a semi-cylindrical groove or shaft'l96'by a'chain 91 which is driven from in# 10 the sprocket ~98 on a shaft 99.
