Description
March 20, 1962 D. R. ANDERSON CEILING MATERIAL HOIST Filed Feb. l5, 1960 INVENTOR.
DA /v/EL R. ANDERSON FI G. Z
L4/Q ATT RNEY port thereon a sheet or board of building material M, PIG. 2, such as a plasterboard ceiling sheet or a Vplywood panel.
When the hoist is tobe used, the head-carrying lifting standard is dropped to its lowermost position where the head frame is convenient to the user. A ceiling board or panel, such as of plasterboard, libreboard, or plywood, is placed on the head frame in a horizontal position, the head frame being disposed at the middle region of the lboard. The head frame is then raised by operating the Winch 31, bringing the horizontal board close to the ceiling structure of the room. The hoist can be Wheeled about to place the board in the desired position. If desired, the head frame can then be raised farther to abut the board against the ceiling. While the head frame is in its elevated position, the board is fastened to the ceiling structure, whereupon the head-carrying lifting standard `is lowered to its loading position, ready for the next operation.
If desired, the hoist head frame may also serve tc support a scaffold board or seat board, not shown, for use in painting, decorating, and other operations.
The hoist can be readily disassembled or knocked-down into the three separable units, 10, 17, and 48, as indicated in FIG. 5, to facilitate transport and storage, and when in such condition can lbe compactly packed. The base and head frame form two of these units, and the extensible ma'st structure, with the three brace bars thereof swung inwardly, forms the third uni-t. If desired, the winch crank handle 43 may be detached and reversed to provide further compactness of the mast structure.
In the modified form of hoist shown in FIG. 6, the lifting cable 45 is trained or looped about a grooved pulley 53 mounted on a bracket 54 welded or otherwise secured to the lower portion of the slidablelifting standard 19, land the end portion of the cable extends upwardly from the pulley and is anchored on a bracket or ear 55 welded or otherwise Ysecured to the guide sleeve 21. This arrangement provides additional mechanical advantage. The hoist of FIG. 6 is otherwise the-same as that of FIG.1.
I claim:
1. A hoist for handling ceiling material and the like, comprising a base, a vertical post upstanding from said base, a tubular lifting standard surrounding and vertically slidable on said post, a guide member spaced above said base and extending about said lifting standard in slidable engagement with said standard, said standard being slidable up and down within said guide member, supporting means connecting said guide member and base, a material support carried by the upper end of said lifting standard, and winch means carried by said guide member at the outer side of said member and including a hoisting cable exterior to said lifting standard and operatively connected to the lower end portion of said lifting standard.
2. A hoist forhandling ceiling material and the like, comprising a base, a vertical post upstanding from said base, a tubular lifting standard surrounding and vertically slidable on said post, a guide member spaced above said base and extending about said lifting standard in slidable engagement with said standard, said standard being slidable up and down within said guide member, three supporting brace bars connecting said guide member and base and being divergent downwardly and outwardly, two of said brace bars being disposed at opposite sides of said standard and lying substantially in a vertical plane of said standard, and the third brace bar lying in a vertical plane of said standard spaced substantially 90 from said first-name plane, -a material support carried by the upper end of said lifting standard, `and winch means carried by said guide member at the outer side thereof and at a region opposite said third brace bar and including a hoisting cable exterior to said lifting standard and operatively connected to the lower end portion of said lifting standard.
3. A hoist for handling ceiling material and the like, comprising a base having an upstanding projection, a vertical post upstanding from said base and having its lower end detachably interfitting with said base projection, a tubular lifting standard surrounding and vertically slidable on said post, a guide member spaced above said base and extending about said lifting standard in slidable engagement with said standard, said standard being slidable up and down within said guide member, inclined brace bars connecting said guide member `and base and being detachably secured to saidV base, a material support carried by the upper end of said lifting standard and having a downwardly extending projection detachably interlitting with the upper end of said lifting standard,
Vand winch means carried by saidv guide member at the outer side of said member-and including a hoisting cable exterior `to said lifting standard and operatively connected to the lower end portion of said lifting standard, the connection of the upper ends of said brace bars to said guide member being pivotal and permitting said brace bars to be swung inwardly close to said lifting standard when said bars are detached from said base and said base I is detached from said post.
4. A hoist for handling ceiling material and the like, comprising a cross-shaped base having four -rigidlyA connected arms extending radially from a junction, a vertical guide post upstanding from said base at said junction, a tubular lifting standard surrounding and vertically slidable on said post, a vertical guide'sleeve spaced above said base and surrounding said lifting standard in slidable engagement with said standard, said tubular standard being slidable up and down within said guide sleeve, said sleeve having thereon a pair of diametrically opposite laterally projecting brackets and an intermediate laterally projecting bracket spaced substantially from said first named brackets, three inclined brace bars having their upper ends respectively connected to said sleeve brackets and having their lower ends respectively connected to three arms of said base, said brace bars being downwardly divergent with respect to each other, a winch mounted on the side of said sleeve opposite said intermediate bracket and including a rotatabletdrum, and a hoisting cable wound on said drum and projecting down- Wardly therefrom exterior to said lifting Vstandard and operatively connected to the lowerend portion of said lifting standard for elevating said standard.
