The other end of the carriage 22 is mounted on rollers 35 which are adapted to run on rails 3G.

The elevator to which the rear end of the carriage'22 and parts sustained thereby is connected, may be raised and lowered by any suitable hoisting device, such as a cable 37 which may be operated by any suitable means. Stops 38 are secured to the rails 23 lon-'the carriage 22 to prevent downward :movement of the mould longitudinally of the carriage while the latter is being tilted. The

,lowerfront vend ot the mould 2O is provided with plate 40 having a mould therein which is closedby a cap l-l which is provided with ylugs 42 adapted to interlock with clips 43 to 'removably-secure the cap in the plate d0 and close theiront end of the mould. rThis cap prevents the concrete from falling through the lower end of the mould while it is-tiljted and eanbe readily removed while the mould Visbeing rotated to pack the concrete therein, as hereinafter more fully set forth. The flanges 2l"l on the mould are 7 adapted to' rest on bearing-balls la (Figs. 6L Vand 6b). Each ball is held in a socket 45 and on a plug 46 which is adjustably sustained by -a screw 47. By adjusting these balls 44,

vthe mould will be evenly supported so it can be easily moved.

'The operation of the charging apparatus willbe as `follows: A mould 20 will bedeposited upon the carriage 22 by a suitable hoist, as well understood in the art. The chute -24 will then be adjusted so that its --spout 25 will discharge concrete into the mould. A lcharge of concrete will be delivered into thehopper 34, the outlet oiwhich is provided'with a valve 34a by which the discharge from the hopper into the chute 2% may be regulated. VThe screw-conveyor 2G will-be started andthe elevator 3l will be gradually raised. As the elevator is raised, the carriage 22 and mould thereon will be gradually tilted and theV concrete will be ygradually and Icumulatively delivered into l the mould. This results in evenly filling the mould. Alter the mould has been tilted approximately to ythe inclination shown by dotted linesfin Fig. jl, the mould will have received the charge of concrete and the eley the carriage Yis restored to its normal position, this aligning device will cause the carriage to bring the mouldy into true position for entry into the rotating mechanism. For the same purpose, a V -shaped block 52 is secured to the base of the tower 3?) and a recessed member 53 is secured to the elevator.I so that as the latter is lowered, the rear end ot the carriage will also be truly aligned.

A drum 55, the axis ot which is aligned with the axis ot the mould held on the ca 1'- riage 22, is located adjacent one end ot said carriage and adapted to receive the mould from the carriage. Drum 55 is scoured in annular trames 5G, each of which is provided with a series of lugs 57 in which are mounted rollers 5S. The latter are grooved and adapted to travel on circular tracks 5t). These tracks are each secured in a stationary trame 60. Frames 5G are formed in sections for convenience in applying them to the drum. Each track 59 is 'formed of semi-circular sections and each sect-ion comprises a tread-portion (5l and a liange G2 bolted to the trame. The fianges of the sections are disposed on opposite sides of the frame GO so vthat they can be conveniently replaced without removing the frame 60. Guide and supporting rails G4- are secured to the sides ot the drum and the horizontal ilanges of these rails are provided with ball-bearings, such as are shown in Fig. 9 and in detail in 6 and 6b, so that the ilanges 2ll on the mould may be easily moved longitudinally along these rails to bring the mould into and out ot the drum. Shafts (3G are mounted in bearings G7 in the drum and the inner ends of these shafts are each provided with a cam 68 adapted to clamp the Ilanges et the mould against the bearings and to hold the mould against longitudinal movement. .kn arm (39 is secured to the outer end ot each cain-shait (SG. Rods 70 at the outer sides ot' the drum are provided with adjustable stop-collars 7l which are adapted to engage the forked ends of the arm GS) to operate them to shift the cam (3S. Each rod 70 is adapted to be operated by a screw 73 which is held in a lug iet iixed to the drum, and has a screw-threaded engagement with a socket 75 which is adjustably connected to one end of the rod. By turnin the screws 7 3, rods 70 may be operated to release the cams 68 or to cause them to lock the mould in the drum. A gear 7 6 is fixed to the drum and may he driven by any suitable nichanism, as well understood in the art.

A cable 77 and a suitable power-operated winding mechanism 7S is guided b v a pulley S() and connected to the Ytrout end o'l' the mould. as at 79. From the drum 55, the mould will be pulled by the cable 77 onto stationary tracks 82. from which it will be removed in any suitable manner. A cable S3 is adapted to be connected to the iear end et a mould in the drum 55 and to the front end ot a mould in the charging` apparatus. so that the charged mould and the mould which civ has been linished in the drum 55 may be sirotated to cause the concrete to be packed CII -flO

around the mould and to form a hollow pole, well understood in the art.` lVhile a mould is being rotated, the cap 4]. is removed.

The inventionthus exemplifies charging c evenly filled and in which no pit is necessary to receive any portion of the mould While tilted. Also one in Which the charging operation and packing operations of different moulds may be simultaneously performed. Also improved means for locking the mould in the druin.

The invention is not to be understood as :restricted to the details set forth, since these may be modified within the scope of the appended claims, Without departing from the spirit Vand scope of the invention.

Having thus described the invention, what I claim as new and desire to secure by Iietters Patent, is:
