VIRCKS ym m ATTORNEYS United States Fatent O ice 3,314,553 WALLBOARD DEVICE FOR WALLBOARDING CEILING William A. Vircks, RED. 1, Stetsonville, Wis. 54480 Filed Feb. 9, 1965, Ser. No. 431,384 8 Claims. (Cl. 214-1) My invention relates to improvements in wallboard devices for placing wallboard on ceilings of rooms and the like.

The primary object of my invention is to provide an easily handled and operated device for quickly and accurately applying a wall board to ceilings, roof joists and overhead floor joists and the like from the floor so as to obviate the use of scaffolding, ladders and braces which are oftentimes both time consuming and expensive.

Another object of the invention is to provide a device of the character and for the purpose above indicated which will enable wallboard to be lifted to the ceiling and held in a sag free position relative thereto until nailed and which will perform the above function without gouging of the bottom surface of the wallboard.

Still another object is to provide a device for applying wallboard to ceilings which is easy to move about from room to room, foldable and collapsible for convenience in transportation and storage or wheeling, which will not get out of order from prolonged use and is comparatively inexpensive to manufacture and use.

Other and subordinate objects also within the purview of my invention, together with the precise nature of my improvement, will be readily understood when the succeeding description and claims are read with reference to the drawings accompanying and forming part of the specification.

In the drawings:

Describing my invention in detail with reference to the drawings by numerals, in the preferred illustrated embodiment thereof, my improved wallboard lifting de vice comprises as its basic elements a base 1, a column assembly 2 and a head 3. The base comprises two base Patented Apr. 18, we?

plates It} and 11 best seen in FIGS. 1 and 5 respectively which are secured to the column assembly by a weldment or other suitable means in spaced apart relationship. The lower plate 11 is permanently secured at the bottom of the column assembly in a plane normal to the axis of the column assembly. The plate 10 is spaced vertically there-from and is parallel thereto.

In the embodiment illustrated, each plate has six side edges of alternate short and long dimension as is clearly illustrated. The plates have been rotated on the base assembly before being permanently secured thereto so that the long and short sides are in arcuate alignment. The upper plate Ill has the upper end of a leg 12 permanently secured thereto as by a weldment or the like. The attachment is located radialy and arcuately of the plate ltl adjacent one of the short edges thereof. The leg 12 is composed of tubing or the like and has a bend 15 which provides that the lower section of the leg will be normal to a floor or support on which it. is to be used. The leg has a caster 16 secured to the lower end thereof. A strut I2 is permanently secured at one end thereof to leg 12 at a point adjacent the lower end of the leg 12 and is disposed radially inwardly and secured permaneatly to the plate ll at its other end. As can be seen in FIG. 5, this strut is secured to that portion of the plate 11 which comprises a short edge.

The base 1 comprises two additional legs 13 and 14 with associated struts l3 and I l which are substantially identical in configuration to the leg 12 and strut 12. These legs and struts are permanently attached thereto. The legs 13 and M are pivotally connected to the upper plate Id by means of a bolt and nut assembly 17 and 18 respectively or other suitable means. The bolts pass through appropriate holes (not shown) in the upper plate llll adjacent the other two short edges of the plate dill. The lower plate 11 has holes 19 and 20 formed therein adjacent the other two short edges thereof as can be best seen in FIG. 5. These holes are adapted to receive the downwardly turned ends of struts l3 and 141. Cotter pins 21 and 22 are passed through transverse bores (not shown) at the ends of these struts and secure the struts to the plate for pivotal movement.

A cover 23 for the lower base plate 111 is provided which has an opening 27 therethrough adapted to mount the same on the column assembly between the two base plates. This cover functions in one position thereof to lock the struts against arcuate movement. Locking of the struts, in turn, locks the legs in an extended position in which they are spaced relative to each other through an arc of a proximately degrees.

The cover 23 has a body portion 24 identical in configuration and slightly larger than the base plate 11. Three flanges 25 extend downwardly from the major edges of the body portion 2d. Openings 2d are provided between the ends of the flanges 25 as clearly illustrated in FIG. 5.

The cover plate is shown in its raised position in FIG. 5. In its lowered position as illustrated in FIG. 1 its function of locking the struts is clearly illustrated.

While the base has been described as comprising three legs, with struts and base plates and a cover suitable in shape for use with this number of legs, it is clear that more than three legs may be used as desired and that the use of more than three legs is within the purview of this invention.

The column assembly 2 is of telescoping form with a cylindrical lower outer bottom section of pipe or the like which has an opening 32 at its upper end. An upper inner telescoping member 31 is received within the opening 32 of the member 30. The member 31 as can be best seen in FIG. 4, has a cross sectional shape such that it provides an annular space between the two members. In the embodiment illustrated, this member is of rectangular configuration. A flexible member 33 in the form of a cable or the like is disposed as illustrated in FIG. 4 between these two members and is secured to the lower end of the upper inner member 31. The purpose of this flexible member will be made apparent hereinafter.

The lower outer telescoping member 30 has a slot 34 at its upper end which communicates with the upper opening 32. Flanking this slot 34 are two plates 35 and 36 which are permanently secured to the upper end of the member 30. A shaft 37 is supported by these two plates and, in turn, mounts a roller 38 thereon. The roller has a peripheral groove 38 adapted to receive the flexible member 33. The shaft and roller are so mounted on the plates 35 and 36 that the flexible member extending downwardly therefrom will be aligned with the annular space between the members 30 and 31 as best seen in FIG. 4 and FIG. 6.

A winch assembly 40 is mounted on the lower outer column member 30. The Winch functions to extend the telescoping members and raise the head which is secured to the upper end of inner member 31. The winch comprises two plates 41 and 42 which are secured to the lower outer telescoping member 30 as can be best seen in FIG. 4.

A spool 43 is mounted between the plates 41 and 42 by a shaft 44 having a handle 45 connected thereto by an arm 46. One of the circular flanges 47 of the spool 43 is oversized forming a Wheel and has slots 48 provided in the periphery thereof. The plates have slots 49 as seen in FIG. 2 adjacent the periphery of the oversized circular wheel flange 47. The slots receive a bolt and nut assembly 50 which is adapted to engage any of the slots 43 in the periphery of the circular wheel flange 47 to lock the spool against rotation. One end of the flexible member 33 is, of course, permanently secured to the hub of the spool 43 (not shown).

The head comprises two plates 51 and 52 secured along one edge by a hinge assembly, preferably of the piano type, which comprises alternate knuckles 54 secured to the plate 51 and knuckles 55 secured to the plate 52. A post 53 is rigidly secured to the underside of the lower plate 52 and is adapted to extend into a recess in the upper end of the upper inner telescoping member 31 which recess is identified in FIG. 6 by the reference numeral 56.

Permanently secured to the upper head plate is a plurality of radially extending strut members 57. Secured to the outer end of these radially extending strut members 57 is a frame assembly 58 of a shape similar to that of wallboard and having dimensions slightly less than the conventional wallboard dimensions. The frame assembly 58 is formed of a peripheral member 59 and transverse members 59'. The peripheral member 59 may be a single deformed tubular member or it may be composed of several lengths of pipe secured together at their ends. The frame assembly 58 is so disposed relative to the plates 51, 52 that one of its major sides is aligned with the piano hinge assembly 54, 55. To this side of assembly 59 are secured one or more flange members 60 and a dependent brace arm assembly 61. The flanges extend outwardly of the side of the frame assembly to which they are secured and turn upwardly as best illustrated in FIG. 1. Their upward extent is of such a dimension that they extend above the plane of the upper side of the frame assembly a distance slightly less than the average thickness of Wall boards. Their horizontal extent is approximately two inches.

The arm assembly 61 comprises two elongate elements 62 and 62' rigidly secured to the frame assembly 58 at their upper ends and converge at their lower ends and are rigidly secured to a plate 63. The plate 63 has a notch therein of a size and shape adapted to bear against the cylindrical member 30. As can be seen in FIG. 2, the arm assembly 61 extends inwardly approximately 20 degrees from the vertical.

The operation of the device is as follows:

With the head pivoted on its hinge to the position shown by the solid lines in FIG. 7, a wall board 70 may be positioned thereon to be supported by the flanges 60. When so positioned the lower longitudinal edge and upper longitudinal edge of the wallboard, as well as the side edges thereof, are spaced beyond the limits of the frame member 58. On the operation of the winch mechanism, the telescoping members elongate. The head is lifted upwardly while still in a tilted position until the upper edge of the wallboard contacts the joists or structure 71 above. Because the frame is tilted from the vertical the wallboard on contact with the structure 71 above will tilt to the right as indicated in broken lines in FIG. 7. Upon further rotation of the winch 40 and raising of the inner telescoping member 31, the frame will be further til-ted on its hinge until the frame assumes the position as seen in FIG. 8.

Since post 53 is loosely received within the opening 56 of the inner upper telescoping member 31 for rotation therein, the upper longitudinal edge of the wallboard 70 can adjust itself to align with the edge of previously installed wallboard 73 as shown in FIGS. 7 and 8.

By reason of the fact that the post 53 can rotate freely in the opening 56 and because the slot in the side of plate member 63 is circular to conform to the outside of the lower cylindrical telescoping member 30, it is clear that the frame may be freely rotated to effectively enable the winch and frame to be advantageously positioned with respect to a corner, obstacle or side wall of the room for easy operation of the device.

If by inadvertence the base has been positioned too close to the previously installed wallboard 73, the head, on the contacting of wallboard 70 with the edge of wallboard 73, will shift the apparatus slightly to the left as seen in FIG. 7 to more readily and quickly align the wallboard for fastening to the structure 71 above.

The upper surface of wallboard 70 and/or the lower surface of structure 71 can be preconditioned as with a suitable adhesive to secure the wallboard thereto. By reason of the fact that the frame 58 is slightly smaller in size than the wallboard to be used therewith and further by reason of the fact that the flanges 60 are offset, 21 marginal portion of the wallboard 70 is presented for the reception of nails, staples or the like which may be used to secure the wallboard to the upper structure 71.

By reason of the fact that the arms 57 extend down- Wardly and inwardly from the frame 58, and are constructed of resilient material such as steel, a certain amount of give is permitted between the frame elements 59 and 59' and the double plates 51, 52. This give enables the frame 59 and the cross members 59 to urge the wall board 70 firmly against the upper structure 71. Sagging of the wallboard is avoided during nailing or securing of the wall board to the upper structure 71 through this operation.

When the tubular member has been extended to a condition as just described, a single operator can lower the bolt 50 into engagement with the slots 48 in the spool flange 47 to hold the telescoping members in this extended position. The single operator can then without danger of the wallboard falling secure the same to the ceiling through suitable fastening means.

It can be seen that the device can be shifted on its casters 16 from one position in a room to another. Moreover, the apparatus can be moved from room to room in a single building. When it becmes desirable to move the apparatus to another location, the device can be disassembled as follows:

With the device in a position such as that illustrated in FIG. 7 but without a wallboard 70 positioned thereon, the head may belifted to remove the post 53 from the opening 56. After removal of the head, the cover 23 may be lifted and the legs 13 and 14 rotated to a position adjacent leg 12 substantially as shown in FIG. 9. In this position the apparatus is readily suited for transportation.

While the novel apparatus has been set forth above as being used with wallboard, it will, of course, be clear that sheet material and slabs of various compositons may be used with the above device.

While there have been pointed out the fundamental novel features of the invention as applied to a preferred embodiment, it will be appreciated that various modifications and changes in the form and details of the device may be made without departing from the spirit and scope of the invention. It is intended that the patent grant be limited only as indicated by the scope of the following claims.
