fky/m @aai? United States Patent 3,305,219 BUILDING BOARD LIFTER Frank Rhodes, 1724 Claremont Ave., Pueblo, Colo. 81005 Filed Oct. 23, 1965, Ser. No. 503,365 Claims. (Cl. 254-1391) The present invention relates to a new and improved building board or dry wall lifter apparatus and more particularly relates to a new and improved assembly machine designed for raising and holding in position building wall boards or dry wall components that are too heavy for one or more men to handle with convenience. The apparatus of the invention is'used for placing and holding boards for being applied to ceilings from ceiling heights of 5 feet 3 inches to 9 feet 6 inches, and for wall applications from the floor to 11 feet 6 inches high, and can be built for greater heights as may be desired.
One of the advantages of the present invention is that it picks the board from off of the floor, moves it with great facility on the machine, which has rubber Wheel casters or the like, to a desired location for application in holding it in place on the ceiling until it is secured to such wall or ceiling. The apparatus of the invention is adapted to receive and hold a 4 foot by 12 foot board through a 30 inch door as long as there is clearance for the board to turn through the door.
By means of the present invention, one man is capable of handling boards of the aforementioned size, or the like, and there are no other known lifting means of comparable advantages, features and objects as those of the present invention with the characteristics here set forth.
The main object of the present invention is to provide a machine for lifting and applying, as well as holding in place, sheet rock or dry wall for being nailed or applied in the construction of ceiling. The machine is adapted to handle other types of Wall board such as Bison Board, Buffalo Board, plywood sheets and Plyscord, among others.
The above and other objects and advantages of the invention will become apparent upon full consideration of the following detailed description and accompanying drawings in which:
FIGURE 1 is a perspective view of the building board lifter means of the present invention showing the essential and preferred arrangement of the present invention;
FIGURE 2 is a cross-sectional view taken along lines 2-2 of FIGURE 1;
FIGURE 3 is a cross-sectional viewfof a base support construction taken along lines 3-3 of FIGURE 1;
FIGURE 4 is a cross-sectional view taken along lines 4-4 of FIGURE 2, showing a detailed construction of the arrangement thereof;
FIGURE 5 is a cross-sectional view in part taken along lines 55 of FIGURE 4;
FIGURE 6 is a cross-sectional view of the tilt locking lever mechanism in detail according to the preferred embodiment of the present invention;
FIGURE 7 is a cross-sectional viewtaken along lines 7-7 of FIGURE 1; and J FIGURE 8 is a broken-away view of the apparatus taken along lines 8-8 of FIGURE 7 in accordance with the preferred embodiment of the present invention.
Referring now to the drawings, there is shown a main frame 10 provided with a set of upright bars 12, 14 for said frame, a wench assembly 16, an intermediate carriage 20, 21), and a main carriage or building board lifter apparatus 22, 22.
A pair of cables 26, 26 is threaded on each side of the carrier and adapted to wind on a cable drum 28 over a pulley 3t 30, under a pulley 32, 32, then back over pulley 34, 34, and'lthen over pulley 36, 36, and then connected to the cable clamp 88, 88, mounted in the main carriage guide roller assemblies 86, 86, which are connected to the main carriage assembly 22, by means of 80, and which moves with the main carriage. Thus the main carriage assembly 22 may move up and down on the intermediate carriage assembly by means of guide roller assemblies 86, 86, in the main carriage assembly. The intermediate carriage assembly 20, 20 moves up and down on the main' frame 12, 12, 14, 14, in FIG. 1, and is guided by guide roller assembly 40, 40, which is sta tionary with the main frame 12, 12, 14, 14, and the guide rollers in the guide roller assembly 42, 42, which move with the intermediate carriage 20.
The main frame is rolled up to the edge of the material to be lifted, and as is evident from the illustration in FIGURE 1, the material 50 is placed on a side edge and is then lifted onto a lip 52, 52, at the bottom edge of the main car-riage 22, and then laid back against the main carriage 22. The main carriage is lifted to clear the floor by winding cable 26 onto the cable drum 28. By turning the crank of the Wench assembly 16, the material 51) is lifted as desired until the crank of assembly 16 is stopped and then it is locked in place by means of a ratchet and dog 56. Then the lifter of the main frame is rolled to a desired location for application of the material 59 to a given position for installation. The cable 26, 26 is wound onto the drum 23 until the main carriage carrier 20 stops against the top of the intermediate carriage 20 where it is again locked in position by means of the ratchet and dog 56. The material is then tilted to posi tion by setting in a nearly vertical position for wall application or to a horizontal position for ceiling application or to any position along line 62, FIG. 2, by means of adjustment of tilt clamp means 70 illustrated in FIG. 6 and described in more detail hereafter. The cable is then further wound onto the cable drum 28- and the inter. mediate carriage 20, 20 raises carrying the main carriage 22 with it to a desired position for application of the material 51 When the tilt lock lever 70, mounted on the main carriage assembly 22, is moved in the direction indicated by the arrow 72 to the position open from what is shown in FIG. 6, it moves a link 74 which moves the locking arm 76 for releasing the clamp at 78 which clamps onto 82, FIG. 7, which is part of the main carriage roller assembly 86 and which allows the main carriage to tilt at pivot in the direction of the arrow 82, FIG. 7, to a desired tilt for applying the wallboard as described above. When the tilt locking lever 70 is moved back to the position as shown in FIGURES 6 and 7, it rotates the link 74 back to a position that is passed deadcenter at lever 84, thereby holding the tilt locking lever at a position which clamps the main carriage at 78. This arrangement allows the operator to release the main carriage tilt lock 70 by moving only one lever with great facility which may also be used to tilt the carriage and then lock the main carriage in its new position by moving the lever back to its original position. This clamping arrangement thus allows the main carriage to be set to any angle from substantially vertical to horizontal and back again.
In the main carriage hinging device, as shown at 92 in FIG. 2, sleeve 95 is fitted so that it can slide back and forth from position as shown by arrow 92, or to a position as shown as element 96 or 98, respectively. When the sleeve is in position as shown by arrow 96, it covers the leg hinge, a portion of the leg 100 and a sufficient portion of the part of the main carriage 22 to which the leg is hinged, to hold the leg in a rigid position with respect to the main frame and in a position to pick up sheets of building board. After the main carriage is tilted to the horizontal position or nearly horizontal position, the sleeve may be moved to position as shOWn at 98, at which position the sleeve no longer covers the leg 1% or the hinge, and the main carriage leg 100 will fold or hinge down, reducing the width of the main carriage, as shown as component 60.
This arrangement allows the main carriage to be reduced in width to 24 inches and also allows the main carriage to be used in clothes closets, halls, and other places of limited size.
Therefore, the device is designed to raise and hold in position building wallboards of conventional size and dimensions, and other fiat components that are too heavy for one or more workmen to handle with convenience. The device of the invention places wallboards for ceiling application from 5 feet 3 inches to 9 feet 6 inches high, and for wall application from the floor to 11 feet 6 inches high, and can be built for greater height within the scope of the invention.
The invention has the advantage of picking the wallboard off the floor, moving it with ease on rubber wheel casters, or the like, to a desired place for application and holding the wallboard in place until it is secured to the wall or ceiling. The device of the invention will take a 4 feet by 12 feet board through a 30 inch door providing there is an end clearance for the board. One man can operate and control the apparatus of the invention and can handle any board that is being installed with its aid. The device of the invention is capable of handling sheetrock and will handle other types of wallboard such as Bison Board, Buffalo Board, plywood sheets and Plyscord, among others.
