PIVO TED HAND TOOL FOR REMOVING DENTS IN SHEET METAL Filed Aug. 50, 1944 Mill; 7k
T Q /Q Patented Feb. 10; 1948 UNITED STATES PATENT OFFICE PIVOTED HAND TOOL FOR. REMOVING DENTS IN SHEET METAL Meredith E. Rohde, Aurora, 0010.
Application August 30, 1944, Serial No. 551,961
1 Claim. 1
This invention relates to new and useful im-' provements in tools for working low spots in sheet metal such as the body and fender of an automobile.
An important object of the present invention is to provide a simplified tool for the convenient reaching of dents and other malformations in fenders and other sheet metal surfaces.
Another important object of the invention is to provide a tool for removing dents and other depressions in sheet metal surfaces by a pick or tap action of a hammerlike element;
Still another important object of the invention is to providea tool for removing or raising low spots in sheet metal surfaces wherein a tapper and an anvil are employed in union, the anvil serving as a marker for the location of the dent while the tapper operating under a fender or other sheet metal article can be operated to tap the low spot accurately with said anvil serving both as a backing and a marker.
Various other important objects and advantages of the invention shall become apparent to the reader of the following description.
In the drawings- Figure 1 is a side elevational view of the tool.
Figure 2 is a top plan View.
Figure 3 is a diametrical sectional view of the anvil.
Figure 4 is a cross section taken on line 4-4 of Figure 1.
Figure 5 is a side elevational view of one of the tapper tips.
Figure 6 is a side elevational view of a modified form of tip.
Figure 7 is a side elevational view showing a third form of tip.
Figure 8 is a fragmentary transverse sectional view showing a modified form of pivot means.
Referring to the drawings wherein like numerals designate like parts it can be seen that numeral 5 denotes an elongated rod having an offset portion 6 at one end with a handle 1 extending therefrom.
The other end of the rod 5 has a yoke 8 provided with inturned pintles 9 which bear into recesses in the side of a disc shaped anvil I which is sufiiciently weighted to serve as an anvil or backing when operating on work.
The disc ID has rounded off upper and lower edges, at its periphery and is formed with a central opening II, the upper side of the opening as shown in Figure 3 flaring into a deeper extent as at l2 and a flare at l3 at the bottom side of the anvil. Obviously the anvil is rotatable within the yoke a, so that either the top or bottom side of the anvil may be used against work and that is the purpose of having the two at cliiferent depths flares l2, l3.
A striker or tapper unit is employed in conjunction with the parts above specified and this consists of an elongated rod having a'bowed portion 14, curved backwardly as at I5 and substantially under the bowed portion [4 as at IS. The end portion of the portion l6 has an upstanding leg ll internally threaded to receive the threaded shank l8 of a conical shaped tapper tip 19. This tip is shown larger in Figure 7 and modified in Figures 5 and 6. Figure 5 shows a tip [9a having a rounded off apex 20, while Figure 6 shows a tip I9b having a truncated apex 21. These tips can be used under certain conditions and kinds of work.
A pivotal connection is provided between the bowed portion l4 and the handle 1 and this consists of an inverted U-shaped connector 22 to which the handle I is properly welded as at 23. The depending portions of the conector 22 are formed with openings 24, 24 for properly receiving ball- bearings 25, 25 which also bear in openings 26 in diametrically opposite side portions of the bowed rod portion l4. In order to obtain the correct bearing surfaces between the ballbearings 25 and the connector 2'2 and bowed portion l4, a bolt 21 provided with a nut 28 i disposed through the connector 22.
A modification of this pivotal connection is shown in Figure 8 wherein the side portions of a connector are denoted by reference character 22a and through these side portions is disposed a bolt 21a, passing through a pair of two-way bevelled bearings 29, which are portions bearing in opening of a bowed rod portion Ma corresponding to the bowed rod portion l4, Figure 1. Obviously the correct bearing relation of these parts can be obtained by tightening or loosening a nut 28a on the bolt 21a.
An anchor member 29 is provided on the bowed portion M of the tapper rod and from this extends a tension spring 30 to an anchor 3| on the top of the connector 22. The purpose of this spring 353 is to always maintain the tapper tip away from the work, always maintaining the rear end portion of the bowed portion I4 away from the handle 1 so that it can be pressed by the operators hand in swinging the tapper toward the work.
In the operation of the tool, it can be seen that the anvil I0 is positioned over the low spot in the work, by the left hand of the operator, while the to strike theglow point of the work and in spite.
of the fact that the tip fl9 may behidden from; View, the anvil ID will serve as a, marker and the tip will always strike the point underlying the openin I l in the anvil. Thus itcanbe seenthat the tool can be accurately operated at all-ti1nes.
The curved shape of both members 5 and 6-is better adapted to contours of moder autornobile bodies and fenders, making possible the reaching of more inaccessible damage also making possible use of the tool when clearance on the reverse side is limited.
While the foregoing speci fication sets forththe invention in specific terms, itist he understood that numerous chan e s in the shape, size and materials may beresorted towithout departing from the spirit and scope of the invention as claimed hereinafter.
Having describedthe invention what is claimed as new is;
"A'sheet metal reforim ing tool comprising an anvil member, a. striker member, said an vil memher, being provided withan elongated arm, said striker member being provided with an elongated arm extending in th'ejsame'general direction as theanvil arm,sa id anvil arm being provided with an offset portion defining a handle, the free end portion of the striker arm being curved inwardly and into the space defined by the offset portion of the anvil arm, a U-shaped connector having its bight portion secured to the free end of the handle portion of the anvil arm, said curved free end portion of the striker arm being formed with openings, spaced from its free end at a pair of diametrically opposite pointsvand; opposed to the leg portions of the connector, the leg portions of the connector being formed with openings opposed to the openings of the striker arm, ball bearingsinterposed between the leg portions of the connector and the last mentioned portion of the striker arm and being seated in the opposed openings, and contracting means between the leg portions of the connector, said curved free end portion of the striker arm being provided with a spring extending and connected to the handle portion of the anvilarm.
