Primary Examiner-Charles W. Lanham Assistant Examiner-Gene P. Crosby Attorney-Bertha L. MacGregor [57] ABSTRACT A tool for pulling out dents in the metal of automobiles. This tool consists of a block having a pair of rod members for insertion into drilled openings in the sheet metal, the tool being adaptable for pulling out dents in areas where access to the rear side of the sheet metal is impossible.

5 Claims, 5 Drawing Figures SHEET METAL PULLER This invention relates to tools for body and fender work and the like.

It is therefore the primary purpose of this invention to provide a sheet metal pulling device which will be used to pull out dents in automobile bodies in areas of the vehicle where access to the rear side of the sheet metal is not available.

Another object of this invention is to provide a device of the type described which will be of blocklike structure having a pair of threaded rods, the rods being insertable in drilled holes in the sheet metal from the front side, the rods being of L- shaped configuration so as to form a bearing surface against the back side of the sheet metal in order that the metal may be pulled outwards in order to repair the damage to the vehicle.

Another object of this invention is to provide a device of the type described which will have eye means for the insertion of jacks or other tools for applying a pulling force upon the metal to be straightened.

Still another object of this invention is to provide a sheet metal pulling device which will include a penplate member for accurately drilling the holes through the sheet metal in order to insert the rods of the device.

Other objects of this invention are to provide a sheet metal pulling device which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and efficient in operation.

These and other objects will become readily evident upon a study of the following specification together with the accompanying drawing wherein:

FIG. 1 is a cross-sectional view taken along the lines 11 of FIG. 2;

FIG. 2 is a vertical side view of the present invention shown in elevation and partly broken away;

FIG. 3 is a plan view of a drill-hole tempered tool for use in drilling holes in sheet metal to accommodate the present invention;

FIG. 4 is a side view of FIG. 3, and

FIG. 5 is a vertical view of a T-bar of use with the invention, the device being shown in elevation.

According to this invention, a sheet metal pulling device is shown to include a rectangular block 11 made of metal or other suitable material. Block 11 is provided with a pair of parallel spaced-apart openings 12 which extend through the entire block 11, positioned centrally between openings 12 is a threaded opening 13 for purpose which hereinafter will be described. One of the openings 12 of block 11 slideably receives an L-shaped rod 14 and the opposite opening 12 slideably receives rod 15 of similar configuration. The ends 14 and 15 of rods 14 and 15 respectively provide a means of engaging the backside 16 of the sheet metal 17 and the front side 18 of sheet metal 17 abuts with the end 19 of block 11 when device 10 is adjusted to pull out the sheet metal 17. The threaded ends 20 of rods 14 and 15, receive nut fasteners 21 which serve to render rods 14 and 15 stationary in order that sheet metal 17 may be pulled upwards. The nut fasteners 21 abut with the end 22 of block 11 when device 10 is adjusted properly and the eyebolt 23 is threaded into opening 13 and provides a means for engaging a jack or other equipment to device 10 in order to apply tension for pulling sheet metal 17 outwards from the internal or other portion of a vehicle (not shown.)

Prior to operating device 10 a dripp tenplate 24 is used in order to properly drill opening 24' through sheet metal 17 in order to place rod 14 and 15 therethrough. Drill tenplate 24 includes a pair of spaced-apart rings 26 having openings 27 for the placement of the drill bit and also includes a central handle 25 for holding tenplate 24 while drilling the openings 24'.

It shall be noted that the use of drill tenplate 24 provides a means of drilling holes 24 so that they will align positively with the rods 14 and 15 which are inserted therein behild sheet metal 17 It shall further be noted that a threaded T-bar 28 having a handle 29 is used on sheet metal 17 in area where the repairman can get behind sheet metal 17.

In use, the rods 14 and 15 are inserted into the opening 24 of sheet metal 17 after the drill tenplate 24 is used. After manipulating rod 14 and 15 so that they overlap, the nut fasteners 21 are tightened upon the threaded ends 20, thus abutting block 11 with the front side 18 of sheet metal 17. With the use of the eyebolt 23, tension is applied to block 11, thus pulling sheet metal 17 outwards, after which the opening 24 are closed with plastic.

What I now claim is:

l. A sheet metal pulling device for auto collision work, comprising a rectangular metal block, L-shaped rod means carried by said block for urging against the back side of sheet metal in places where workman have no access to the back side of the sheet metal, an eyebold carried by said block to provide engagement means for a jack or the like, nut fastener means carried by said block providing adjustment means for said rods and retaining means for said rods of said block.

2. The combination according to claim 1, wherein said block is provided with parallel spaced-apart openings therethrough, said openings slideably receiving the L-shaped rods, said L-shaped rods providing engagement means for the back of sheet metal to be pulled outwards on a vehicle or the like and tenplate tool means provides the proper spacing for drilling the openings for receiving said rods through said sheet metal of said vehicle.

3. The combination according to claim 2, wherein said nut fasteners are removed from said rods in order to manipulate said rods at their short ends within said drill openings of said sheet metal, after which the rods are overlapped so to engage the back side of the sheet metal of the vehicle in order to pull said sheet metal outwards.

4. The combination according to claim 3, wherein said rods are manipulated freely by being disengaged from said block of said device in order to allow said short ends of said rods to be properly placed behind said sheet metal and when said rods are placed within said openings of said block and said nut fasteners are threaded onto the threaded ends of said rods until one end of said block is in abutment with the front side of said sheet metal, and said short ends of said rods serve as bearing means against the backside of said sheet metal when said device is pulled by means of a jack or other device.

5. The combination according to claim 4 wherein said eyebolt is threadingly engaged with a threaded opening centrally between said openings for said rods, and allows a tensile force to be applied to said device by means of jack engaging the eye portion of said eyebolt, thus said device is used to pull said sheet metal outward and said openings of said sheet metal are closed with plastic after said rods are disengaged from said sheet metal by removing said nut fasteners therefrom.

Claims (5)

1.
