Abstract

An auto body and frame puller which includes a generally horizontal box girder base member supported on casters for moving from place to place. An upright post is supported from the base member and has a plurality of vertically spaced eyes for attachment of one block of a block and fall. A winch on the base member is provided for winding in the block and fall cable under power. A hook is provided on a second block of the block and fall for attachment to a portion of the frame to be straightened and a second hook on the outer end of the base member has a chain attached thereto for connection to the opposite side of the frame to be straightened. Operation of the winch causes the second block to move toward the post to pull on the portion of the frame to be straightened. The first block can be hooked into anyone of the eyes on the post to vary the direction of the pull with respect to the horizontal.

An upright post is supported from the base member and has a plurality of vertically spaced eyes for attachment of one block of a block and fall. A winch on the base member is provided for winding in the block and fall cable under power. A hook is provided on a second block of the block and fall for attachment to a portion of the frame to be straightened and a second book on the outer end of the base member has a chain attached thereto for connection to the opposite side of the frame to be straightened. Operation of the winch causes the second block to move toward the post to pull on the portion of the frame to be straightened. The first block can be hooked into anyone of the eyes on the post to vary the direction of the pull with re spect to the horizontal.

5 Claims, 7 Drawing Figures 1 AUTOBODY AND FRAME FULLER BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is directed to an auto body and frame puller.

2. Summary of the Invention The auto body and frame puller includes an elongate base member supported on casters and carrying an up right post thereon. The post has a plurality of vertically spaced block and fall attaching eyes and a winch onthe base member is provided for winding in the cable of the block and fall. An opposition chain is connected to the far end of the base member for connection to the opposite side of the object to which the block and fall is attached so as tospread the device being straightened as the winchis operated.

The primary object of the invention is toprovide a complete self contained auto body and framepuller actuated byan electric winch.

Other objects and advantages will become apparent in the followingspecification when considered in the light of theattached drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of the invention; FIG-2 is a top plan view of the invention;

FIG. 3 is-a bottom planview of the invention;

FIG. "4 is a vertical longitudinal sectional view,taken DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings in detail, wherein like reference characters indicatelike parts throughout the several figures, the reference numeral indicates generally an automobile body and frame puller constructed in accordance with the invention.

The automobile body andframe puller 10 includes an elongate box girderbasemember 11 arranged in generally horizontal relation supported on a transverse horizontal plate 12 having a peripheral upstanding flange 13 rigidly secured thereto. The plate 12 and flange 13 form trays for tools and parts. Casters 14 are secured to the tray 12 on opposite sides thereof for supporting the plate 12 and thereby the base 11.

A rectangular socket 15 is slidably engaged over the base member 11 and is secured in adjusted position therealongby set screws 16. A bar 17 extends horizontally across the bottom of therectangular socket member 15 and supports a pair of casters l8 therebeneath at opposite ends thereof. The socket l5 and casters 18 support the outer end of the base member 11. A generallyrectangular socket member 19 is rigidly secured to the outer ends of the base member 11 and has a chain hook 20 rigidly secured to the upper portion thereof.

along the line 4'4 of FIG. 2, looking in the direction A socket member 21 encompasses the base member 11 at the end thereof opposite the socket member 19 and is rigidly secured thereto by welding of the like. An eye beam 22 has its lower end rigidly secured to the socket member2l and slopes upwardly and forwardly therefrom. A generally rectangular socket member 23 is rigidly secured to the upper end of the eye beam 22 and has an upright post 24 rigidly secured therein ina position overlying and aligned with the base member 11. A pair of angular braces 25 are rigidly secured to opposite sides of the eye beam 22 adjacent the lower end thereof and to the lower end of the post 24 on opposite sides thereof. A second pair of angular braces 26 are rigidly secured to opposite sides of the base member 11 and to opposite sides of the lower portion of the post 24.

the eyes 27. Anelectric winch 32 ismounted on the basemember 11 under the post24 and has a cable 33 wound thereon and extending outwardly therefrom. The cable 33 has its farend connected to a hook 34 which is engaged with a second selected one of the eyes :27. The cable33 is trained overadoublepulley block 35 carryinga hook 36 and is trained over the singlepulley block 30 prior to extending to the hook 34. Operation of the winch draws the cable 33 inwardly so as to move the block 35 toward the block30 to draw the hook36toward the post24.

In the use and operation of the invention base member 11 is rolled under a vehicle to have its frame straightened or some portion of its body straightened and the hook -29 isengaged with one side of the object to be straightened and the hook36 isengaged with the opposed side ofthe same object. The electric winch 32 is then actuated to cause the object to be pulled until straight whereupon the pressure is released. By moving the block 30 to other of the eyes-27 the direction of pull with respect to the vehicle can be adjusted.

The socket member 15 can be adjusted longitudinally of the base member 11 so as to give the desired support when needed. I

Having thus described the preferredembodiment of the invention it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the spirit of the invention.

What is claimed is:

1. An automobile body and frame puller comprising an elongate generally horizontal base member, means supporting said base member for movement from place to place, a post positioned above said base memberand extending perpendicularly thereto with its lower end spaced above said base member, a beam rigidly secured to one end of said base member and sloping upwardly and toward the other end of said base member, means securing the upper end of said beam to said post adjacent the upper end of said post rigidly supporting said post, brace means extending angularly downwardly from the lower end of said post to said base member, brace means extending angularly downwardly from the lower end of said post to said beam, a plurality of vertically spaced eyes secured to said post, a block and tackle selectively connected to one of said eyes, an

electric winch mounted on said base member beneath the lower end of said post with the cable from said block and tackle wound thereon, and means on the outer end of said base member for connecting to one side of an object to be straightened with said block and tackle connected to the opposite side of an object to be straightened.

2. A device as claimed in claim 1 wherein said base member is a generally rectangular box girder member.

3. A device as claimed in claim 1 wherein a tool and parts tray is rigidly secured to one end of said base member and the means for supporting said base memadjusted position thereon.
