Referring to
The frame 10 has two vertical tubes 12, 14, a top tube 16 and a bottom tube 18 where each tube can be made of one inch square aluminum tubing. Each vertical tube has a length of forty seven and one half inches and the top and bottom tubes have a length of about sixteen inches. The top and bottom tubes are securely attached to the vertical tubes to form a square frame where the distance between the outside surfaces of the vertical tbes is fourteen and one quarter inches. This distance of fourteen and one quarter inches is the distance between two adjacent studs. Thus, the vertical tubes can be located between two adjacent studs. The ends 20 of the top and bottom tubes extend beyond the outside edges of the vertical tubes by about one and three quarters of an inch. Therefore, the vertical tubes of the frame can be placed between two adjacent studs but cannot fall down between the studs because the ends 20 of the top and bottom tubes extend beyond the stud spacing and rest of the studs.
The bottom tube 18 has a centrally located cutout 22 which has a length that is slightly greater than one and three quarters of an inch. This cutout can be formed by either cutting a notch in the side wall of the bottom tube or by attaching two short pieces of metal which are spaced apart by a distance that is slightly greater than one and three quarters of an inch to the side wall of the bottom tube. This cutout, when located on a stud, will center the bottom of the frame on that stud. Attached to the top tube 16 is a spring loaded clip 24 which allows the top of a panel of sheetrock or plywood to be clamped to the frame. The clip also has a one and three quarters of an inch cutout 26 which is located at the center of the frame. This cutout, when located on a stud, will center the top of the frame on that stud. The spring loaded clip 24 can swivel one hundred and eighty degrees and drop below the top of a panel of sheetrock being carried by the frame to allow the sheetrock to be located close to a ceiling.
A flat relatively rigid member of aluminum 28 which is slidably attached near the bottom of the vertical tubes has a centrally located handle 30 which is provide to lift the frame and a panel of sheetrock or plywood attached to the frame. The height of the slidable flat member 28 is adjustable and can be locked to a desired position with wing nuts which are threaded onto locking bolts. A second flat relatively rigid member of aluminum 32 is slidably attached near the top of the vertical tubes has a handle 34. This handle is provided to allow a worker's shoulder to rest against it.
A flexible strap 40 attached to vertical tube 12 or 14 is provide to sling over a workers shoulder and held in his opposing hand when the frame is being lifted on the workers back. An upper handle 34 at the top allows a worker to carry a panel of sheetrock or plywood with one arm thus freeing the other arm to allow a worker to lower a tailgate, or open a door without setting the sheet of drywall or plywood down
The bottom of the frame is adapted to receive detachable swivel type of wheels 36 which allows the frame and a panel of sheetrock or plywood to be rolled to a work site or used as a stand to provide a vertical cutting table by clamping the material to the top of the frame.
When nailing a four foot by eight foot panel of sheetrock horizontally to a wall, the four foot center line of the sheetrock is aligned with the center of cutouts 22, 26. Thus, four feet of the sheetrock extend out to the left of the center of the cutouts and four feet of the sheetrock extend out to the right of the center of the cutouts, and the cutouts 22, 26 are located at the center of the eight foot dimension of the sheetrock. Now, by placing the cutouts 22, 26 on a stud, the eight foot dimension of the sheetrock spans seven studs where the edges of the sheetrock are located at the centers of the studs at the ends of the sheetrock, and the panel of sheetrock can be easily and quickly nailed or screwed to the studs. In addition, the fourteen and one quarter inch spacing of the vertical tubes will fit between two adjacent studs that are located on sixteen inch centers and, therefore, by placing the frame between two studs the frame will also act as a lining tool when the panel of sheetrock is centered on it.
The bottom 18 allows a worker to install a lower panel of sheetrock raised off the floor properly and still allow the frame to be removed after nailing.
It is understood that the frame 10 can also be used to hold and position panels of sheetrock vertically as well as horizontally.

Attached to the top member of frame 60 is a spring loaded clip 70 which allows the top of a panel of sheetrock or plywood to be clamped to the frame. The clip has a one and three quarters of an inch cutout 72 which is located at the center of the frame. This cutout, when placed on a stud, will center the top of the frame on that stud. The spring loaded clip 24 can swivel one hundred and eighty degrees and drop below the top of a panel of sheetrock being carried by the frame to allow the sheetrock to be located close to a ceiling. A relatively rigid member of aluminum 74 having a swingable handle 76 is securely attached near the bottom of the vertical members of the frame. A second relatively rigid member of aluminum 78 having a swingable handle 80 is securely attached near the top of the vertical members of the frame. When attaching panels of sheetrock or plywood to studs located on sixteen inch centers, the frame of
