Abstract
Abstract A turnover device for rotating a longitudinal member having a center of gravity and carried by a supporting member having a supporting surface is disclosed. The turnover device has a frame disposed adjacent the supporting member, a tilting member on one side of the frame and a receiving member adjacent the tilting member on the side of the frame. The tilting member and receiving member are movable on the frame. Drive means are connected to the tilting member and the receiving member for moving the tilting member and the receiving member from a normal rest position coincident with or below the supporting surface to a longitudinal member tilting position so that the tilting member engages the longitudinal member and rotates the longitudinal member beyond the center of gravity, thereby causing the longitudinal member to fall back onto the support member during the retracting movement of the tilting member and the receiving member.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
176 words
A turnover device for rotating a longitudinal member having a center of gravity and carried by a supporting member having a supporting surface, said turnover device having: a. a frame disposed adjacent said supporting member; b. a tilting member on one side of said frame; c. a receiving member adjacent said tilting member and on the other side of said frame; 1. said tilting member and said receiving member being movable on said frame; d. drive means connected to said tilting member and said receiving member for moving said tilting member and said receiving member from a nominal rest position coincident with or below said supporting surface to a longitudinal member tilting position above said supporting surface so that said tilting member engages said longitudinal member to lift said longitudinal member off said supporting surface during the rotation of said longitudinal member and rotates said longitudinal member beyond said center of gravity thereby causing said longitudinal member to fall back onto said supporting member during the retracting movement of said tilting member and said receiving member.
Claim 2
Dependent Claim
176 words
A turnover device for rotating a longitudinal member having a center of gravity and carried by a supporting member having a supporting surface, said turnover device having: a. a frame disposed adjacent said supporting member; b. a tilting member on one side of said frame; c. a receiving member adjacent said tilting member and on the other side of said frame; 1. said tilting member and said receiving member being movable on said frame; d. drive means connected to said tilting member and said receiving member for moving said tilting member and said receiving member from a nominal rest position coincident with or below said supporting surface to a longitudinal member tilting position above said supporting surface so that said tilting member engages said longitudinal member to lift said longitudinal member off said supporting surface during the rotation of said longitudinal member and rotates said longitudinal member beyond said center of gravity thereby causing said longitudinal member to fall back onto said supporting member during the retracting movement of said tilting member and said receiving member.
Claim 3
Dependent Claim
15 words
The turnover device recited in claim 1 wherein said tilting member has a serrated surface.
Claim 4
Dependent Claim
15 words
The turnover device recited in claim 1 wherein said receiving member has a smooth surface.
Claim 5
Dependent Claim
27 words
The turnover device recited in claim 1 wherein said drive means oscillates said tilting member and said receiving member between said rest position and said tilting position.
Claim 6
Dependent Claim
27 words
The turnover device recited in claim 1 wherein said drive means reciprocates said tilting member and said receiving member between said rest position and said tilting position.
Claim 7
Dependent Claim
19 words
The turnover device recited in claim 1 wherein said tilting member has a tilting surface provided with a protuberance.
Claim 8
Dependent Claim
19 words
The turnover device recited in claim 1 wherein said tilting member has a tilting surface provided with a cavity.
Claim 9
Dependent Claim
20 words
The turnover device recited in claim 1 wherein said tilting member has a tilting surface provided with a pointed protuberance.
Claim 10
Dependent Claim
20 words
The turnover device recited in claim 1 wherein said tilting member has a tilting surface provided with a pronged protuberance.
Claim 11
Dependent Claim
19 words
The turnover device recited in claim 1 wherein said tilting member has a tilting surface provided with a corrugation.
Claim 12
Dependent Claim
20 words
The turnover device recited in claim 1 wherein said tilting member has a tilting surface provided with a lipped protuberance.
Claim 13
Dependent Claim
46 words
The turnover device recited in claim 1 and having: a. a centering device disposed adjacent said supporting member and engageable with said longitudinal member after rotation of said longitudinal member by said turnover device for returning said longitudinal member to the centerline of said supporting member.
