Abstract
Abstract An installation for a truck cover comprising a bow pivotally mounted on an axis on the sides of a truck body, said bow extending from the axis thereof to a position adjacent the front end of the body where there is mounted a rotary shaft with a cover rolled on it, the cross piece of the bow being attached to the leading end thereof; said bow including legs extending to the opposite side of the pivot axis for a short distance with cables attached to extreme end portions thereof and wound on the shaft so that when the shaft is rotated in one direction the cover is mechanically extended to completely cover the truck body and when the shaft is rotated in the opposite direction the cover is wound on the shaft.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
204 words
The combination with a container having a bottom, side and end walls and an open top, and a cover therefor, a rotary shaft extending transversely of said container adjacent an end thereof, the cover being rolled about said shaft and having leading end, means to turn the shaft in both directions, a bow, said bow including a pair of side members, means pivoting the side members on an axis intermediate the ends thereof to the side walls of the container, said bow including a cross member parallel to the shaft, the leading end of the cover on the shaft being connected to said cross member, a cable having an end connected to wrap on said shaft, at least one of said bow side members including an extension beyond the pivot axis, the pivot axis being intermediate the ends of the arm of the bow, the other end of the cable being connected to the extending end of said bow side member, rotation of the shaft in one direction tensioning the cable and pivoting the bow in one direction extending the cover over the truck body, rotation of said shaft in the opposite direction drawing the bow back and wrapping the cover onto the shaft.
Claim 2
Dependent Claim
204 words
The combination with a container having a bottom, side and end walls and an open top, and a cover therefor, a rotary shaft extending transversely of said container adjacent an end thereof, the cover being rolled about said shaft and having leading end, means to turn the shaft in both directions, a bow, said bow including a pair of side members, means pivoting the side members on an axis intermediate the ends thereof to the side walls of the container, said bow including a cross member parallel to the shaft, the leading end of the cover on the shaft being connected to said cross member, a cable having an end connected to wrap on said shaft, at least one of said bow side members including an extension beyond the pivot axis, the pivot axis being intermediate the ends of the arm of the bow, the other end of the cable being connected to the extending end of said bow side member, rotation of the shaft in one direction tensioning the cable and pivoting the bow in one direction extending the cover over the truck body, rotation of said shaft in the opposite direction drawing the bow back and wrapping the cover onto the shaft.
Claim 3
Dependent Claim
38 words
The combination of claim 1 including a one-way clutch brake for said shaft holding the same in selected position, and means for releasing the one-way clutch brake so as to allow rotation of the shaft in either direction.

Dependent Claim
199 words
A truck cover for an open truck body having a side wall comprising a shaft adjacent one end of the truck body, means to rotate the shaft in either direction, a flexible free-ended elongated cover member on the shaft, rotation of the shaft in one direction winding the flexible cover member onto the shaft, a cable wound on the shaft in a direction to wind the cable on the shaft upon rotation of the shaft in a direction opposite to the direction of rotation of the shaft in winding up the flexible cover member, a lever pivoted to the wall of the truck body at a point removed from the shaft, the fulcrum of said lever being intermediate the ends thereof, one end of the lever being secured to the free end of the flexible cover member and the other end of the lever being secured to the opposite end of the cable from the shaft, rotation of the shaft to wind up the cable causing the lever to move to unwind the flexible cover member and carry it over the truck body, and rotation of the shaft to wind up the flexible cover member uncovering the truck body.
Claim 9
Dependent Claim
199 words
A truck cover for an open truck body having a side wall comprising a shaft adjacent one end of the truck body, means to rotate the shaft in either direction, a flexible free-ended elongated cover member on the shaft, rotation of the shaft in one direction winding the flexible cover member onto the shaft, a cable wound on the shaft in a direction to wind the cable on the shaft upon rotation of the shaft in a direction opposite to the direction of rotation of the shaft in winding up the flexible cover member, a lever pivoted to the wall of the truck body at a point removed from the shaft, the fulcrum of said lever being intermediate the ends thereof, one end of the lever being secured to the free end of the flexible cover member and the other end of the lever being secured to the opposite end of the cable from the shaft, rotation of the shaft to wind up the cable causing the lever to move to unwind the flexible cover member and carry it over the truck body, and rotation of the shaft to wind up the flexible cover member uncovering the truck body.
