Application Marclr 1e, 1945; Srial No. 533,075 mass (01. 53251):

This presentinvention; relates to a device: for restoring the original ,shape of hoods an d/or fenders of automobiles or trucks or partsof other vehicles that have had; theseqpertshdeformed in a collision or otherwise. V v

This so-called jig canbe placed on the floor of an automotive repair shop andcornprises pairs of coacting screw or hydraulic jacks engaging-the deformed part of ahood oriender andrestoring its original shape. The position of the jacks, is adjustable. V t

On the front side of the apparatus and "on either side thereof are-fastened Ttwo a'djustabl'e. arms intended to support theautomobile or other vehicle part to be restoredto; its original shape;v

It will be understood that theuconstructionfof the presentinventionlend's itself readily, to other uses including, for example, pressingvoutzcross head, pins in the installation: of new hearings .in a vehicle part; and:'during the:overhauling; of a". front end assembly the spindle bearings, Wrist:= pins or the like can be pressed out.

InsteadLof wooden..frameiriia'terial as shown herein, the parts appropriate thereto can be made of channel or angle' ironi- To the foregoing objects and others which may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts as will be moresp'ecifically referred to and illustratedjn'the accompany-mg drawingsrbutit is tobe understoodv that changes, variations and modifications mayibe resorted to which fall within the 500138.,Off'fthil'lVQl'ltiDhlfiS claimed.

Figure 5 is a fragmentary vi'ew taken on the 1ine--5'--5 of Figure -3.

In Figure 1, numerals 2 denote base pieces of wood or metal, or other suitable material of sufficient length to give the apparatus the required stability. Vertical columns 3 are attached to the inner sides and approximately at the center of the base pieces 2. To insure a rigid connection between the parts mentioned, inclined braces 4 are secured by screws, bolts, or other fastening means 5 at their lower end to the inner side of pieces 2 and at their upper ends by fastening .taken 2' A means ii-to the columns 3. The latterareeach provided w-ith a pair of series of equidistant holes 'l eXtending parallelly and'adjacent to the 1 narrower edges of the columns 3, These are c01' 1- s d. by W 58138 o os b s. 8, a h e consistingoiapair of parallel beams.

l8 and its work engaging member 20 makes it possible to place the latter in a position in which its curvature is that which the hood or fender portion in engagement therewith originally possessed and which is to be restored.

In order to hold a fender or hood to be operated on in the proper position arms 28 are provided each consisting of a lower inner section 29 and upper outer section 30 telescoped over the former. Section 29 is connected by a knuckle joint to one rp's tiqn of. he iero r pii I of the base pieces 2. The knuckle joint comprises a ball portion 3i constituting the lowermost end of section 29 and a plate 32 aimed to base 2 having an aperture large enough for the section to describe a conical surface, but too small for the ball 3i to pass through.

A set screw 33 is threaded into the upper sec tion 39 and engages the inner section 29 with its inner end. Thus the length of the arm 28 may be adjusted to suit the requirements of a bending or straightening operation. In order to permit a further adjustment of the arms 28, each upper section 38 is made in two portions 34, 35 flattened at the apertured coaching ends and held in a desired angular relation by a screw bolt 35 with a wingnut 31. The top portion 35 of section 39 is longitudinally slotted (38) at its upper end to receive a part of the work which is held in the slot by a set screw 39, threaded into one of the legs of slot by a wing head.

Figure 4 illustrates a modification in which hydraulic or pneumatic jacks are used and which dispenses with the upper cross bars of the upper beam and the lower cross bars of the lower beams. Thus the jacks engaging the top surface of the work are suspended from the lower cross bars of the upper beams and the jacks engaging the bottom surface of the work are secured on the upper bars of the lower beam. In other respects the modification of Figure 4 conforms to the preferred embodiment illustrated by Figures 13.

Each fluid jack used in the embodiment of Figure 4, comprises a base 49 attached by bolts 4| or other fastening means to a cross bar l2 as outlined above, a housing 42 carried by the base 40 and including a pump structure, and two telescopically related pistons 43, 44 slidable in the housing 42. The pump structure consists of a fulcrum link 45 pivoted at one end to the housing 42 and at the other end to a. lever 46 which is a socket for a detachable handle 41 and which is also pivoted to a pump plunger 48.

The innermost jack plunger 44 carries at its upper end a work engaging member 49 which is a duplicate of the member 20 of Figures 1-3 and is secured to its plunger in the same or similar manner in which that member is secured to its screw l8 (Figures 1-3). The embodiment of Figure 4 includes also a pair of arms 28 (Figures 1-3).

Operation If a hood or fender is brought in that is deformed, the screws It! or plungers 43, 44 are sufficiently retracted to permit the insertion of the deformed work portion between the members v20 or 49. The portion of the work extending from the apparatus is clamped in the slot 38' by screws 39. Then the screws or jack plungers are caused to move towards the work and restore the original shape.

It will therefore be apparent that I have devised a very practical and highly efficient apparatus well adapted for the carrying out of all the objects of the invention, and that while I have pair of columns each secured at its lower end by diagonal braces to one of the base pieces and having near either of two longitudinal opposite edges a series of spaced holes, two vertically spaced sets of beams bridging the space between the columns and havin secured to either end a pair of apertured angle irons, bolts, each passing through an angle iron aperture and a selected hole in a column, a plurality of cross bars each countersunk in the upper and lower surface of each set of beams, a flanged bushing interiorly and exteriorly threaded, carried by each cross bar, a lock nut for each bushing, a jack depending from each upper cross bar of the upper set of beams through said bushing and guided by the bushing of a lower cross bar of that set, a jack rising from a flanged bushing carried by the upper cross bar of the other set and guided by a bushing in a lower cross bar of that set, each jack having a work engaging member in confronting relation to another member of the other set, and means adjustably connected to each base piece and adjustable as to length and angularity for clamping and holding the work operated on.

2. An apparatus as set forth in claim 1, wherein said work engaging member includes a soft covering and means securing said covering to said member.
