Abstract
Abstract An apparatus for straightening damaged automobile frames or bodies utilizing a rigid structural ramp capable of supporting a vehicle. A preferably hydraulic power source capable of imparting alternatively a compressive or a tensile force to the damaged frame or body is adjustably mounted on a wheeled post which slidably travels a continuous track circumventing the ramp. The ramp is provided with improved chain anchoring openings. A chain can be used for a applying tensile force to the frame directly or indirectly to the frame by connecting a chain first to the anchoring opening, then to the damaged frame, and then to the hydraulic power source. Using two wheeled posts on the continuous track, a rotatable, pivotal, cross bar can be attached at its respective end portions to the wheeled posts. With the power source mounted on the cross bar, repairs can be made to the roof, or interior portions of an automobile (see FIG. 10).

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
231 words
An anchoring system for anchoring the end of a continuous length of chain to a surface on a machine, such as for example a vehicle frame straightener, to anchor the chain length to the machine to prevent any movement of the anchored portion of the chain with respect to the machine, comprising: a. a four-sided opening in said surface having four, straight sides with opposed connecting corners, said opening having sufficient size to receive into and through it the continuous chain length with a minimum width in its central portion greater than the maximum width of each chain length of the length of chain, and b. notched means for preventing removal of the continuous chain length from said opening, said notched means comprising two elongated, opposed slots of equal length, each of said slots being openly connected to opposite ones of two of the opposed corners of said four-sided opening and having a length at least as great as the largest width of each link of the length of chain, a central portion of the continuous chain being located down through said opening with space, separated links of the continuous chain length being located in said opposed slots, with the links extending vertically with respect to the surface, and with the central portion of the continuous chain length being anchored hanging loosely through said opening between the links in said slots.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
59 words
The anchoring system of claim 1, further comprising peg means for sealing said opening and further securing the central portion of the chain length down in said opening, said peg means comprising an elongated member placeable vertically down within said opening and having a four-sided cross-section in a lateral plane, corresponding to the size and configuration of said opening.
Claim 4
Dependent Claim
12 words
The anchoring system of claim 1 wherein said opening is square shaped.
Claim 5
Dependent Claim
26 words
The anchoring system of claim 1 wherein said opening is diamond shaped, and said slots are located at the ends of the longer dimensional opposed corners.
