This invention pertains to the lifting and tilting of a container of fluent materials. Two embodiments are shown, one having a vertical column disposed to carry the secured container to a predetermined height. This apparatus may be fixed or may be movable from and to selected positions. A slot is formed in this column and a reciprocable movable plate is cycled up and down therein. A spur gear and meshed pinion are provided therein. The spur gear is rotated by an arm and cam follower on the end thereof, with the cam follower transverse an angled cam track to provide a determined tilt and rate of tilt. A second and telescoping embodiment is also disclosed for conditions in which the lift may be as much as twelve feet or more. Side and front discharge apparatus is shown. Container securement apparatus includes adjustable pins. A clamping arrangement for cylindrical containers with a tapered end is also contemplated. A battery-powered apparatus is shown particularly for the telescoping apparatus.

Apparatus for lifting and tilting a drum and like containers of flowable materials brought to a lift device whereat the container is lifted to a desired height above the floor, and during said lift a determined tilt is made to an established angle at which the material in the container is discharged, this apparatus including: (a) a base support; (b) a tubular column arrayed in a substantially vertical attitude and secured to said base support; (c) a slot formed in this column and providing an access opening to the interior of said column, this slot extending for much of the length of this column; (d) a container support having a bottom portion adapted to receive and retain the weight of the container; (e) means for retaining the container in a placed condition on the container support during lift and tilting of the container; (f) movable plate positioned within the tubular column, this plate having cam follower-type rollers secured to the plate; (g) U-shaped channel members attached to the column and providing retaining guideways for the cam-follower rollers on the movable plate so that said plate may be cycled up and down the column; (h) a pinion and meshed spur gear carried on and by said movable plate, the pinion fixedly carried on a rotatable output shaft, with the end portion of said shaft extending through said slot and adapted for securing to the container support, and the spur gear carried on another shaft and rotatable thereon; (i) a selectively actuated lift-and-lowering means adapted to move the movable plate and the rollers thereon in the U-shaped tracks including a reversible pneumatic motor having an output shaft on which is mounted a roller chain sprocket which is adapted to cycle a roller chain therein, the roller chain arranged so that both ends are attached to the movable plate, and means attaching the lifting-and-lowering means to the movable plate; (j) an arm secured to said spur gear so as to move said spur gear as the arm is moved, and said arm having a cam follower-type roller thereon; (k) a cam track secured to the column and adapted to receive and retain said roller on the end of the arm associated with the spur gear, this cam track having an angled portion adapted to engage the cam follower and cause the spur gear to rotate a determined amount, this motion causing rotation of the spur gear and meshed pinion so that a determined rotation of the pinion shaft is made, (l) means attaching the output shaft to said container support so that during the lift of the movable plate the secured container is lifted and, when the roller on the end of the arm associated with the spur gear is moved in the cam track, said container support and the retained container are tilted to a discharge position, and the lowering motion is adapted to bring the now emptied container and support to the “start”condition and position; and (m) the end of the tubular column being closed by a base plate on which is secured a bracket adapted to rotatably retain a second roller chain sprocket which is disposed to carry and redirect the roller chain attached to the movable plate, and the base plate carrying a secured stop post having adjusting means to limit the downward movement of the movable plate.
