W ATTORNH Patented Apr. 15, 1930 UNITED STATES WILLIAM FERGUSON, OF FLINT, MICHIGAN SHEET-METAL BUMPING-OU'I. TOOL Application filed may 4, 1928, Serial No.
This invention relates to bumping-out tools to be used in removing indentations from sheet metal, and more particularly for use inbuniping out indentations in automobile bodies due to collisions and accidents, and the invention has for its object to provide a tool of such class, in a manner as hereinafter set forth for reaching a certain part of an automobile body without the necessity of tear ing down the inner frame or supporting structure to get at the indentation in the metal for the purpose of bumping it out.
In removing indentations from the sheet metal body and fenders of an automobile it is now the ordinary practice to hold a metal block or dolly against the inner face of the indented structure while blows are delivered by a hammer to the outer-surface of this structure. It frequently happens however that access to the inner surface of the portion of the automobile that is indented is obstructed by adjacentbraces, beams or backing frame so that the dolly or bumping-out block can not be placed against the inner surface of the indented structure until this obstructing inner structure has been removed.
The present invention is therefore directed to a bumping-out tool or tools having a relatively thin blade-like anvil adapted to be inserted between an indented portion of an automobile and a closely adjacent brace, beam or supporting structure so that the indentation may be bumped out without necessitating the removal and subsequent replacement of the adjacent inner supporting structure.
In bumping out metal the bumping-out tool held against the work should be sufiiciently heavy to cause its inertia of rest to resist the bumping-out blows of the hammer, but when a blade-like anvil such as contemplated by the present invention is employed to back-up the metal surface being bumped-out, the weight or inertia of rest of this anvil may not be sufiicient to resist the blows ofthe hammer.
To overcome this difficulty the present in- 275,216. Renewed September 27, 1929.
vention contemplates a construction in which the blade-like anvil is provided with a relatively heavy handle which is positioned in spaced relation to the anvil where it will be out of the way of the supporting structure 5Q disposed adjacent thesurface to be bumpedout, and the heavy handle and blade are connected by a coupling portion that is sufficiently rigid to impart the blows against the anvil to the heavy handle.
Vith the foregoing and other objects in view the invention consists of the novel con-' struction, combination and arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings, wherein'is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.
In the drawings wherein like reference characters denote corresponding parts throughout the several views Figure 1 is a side elevation, broken away, i of a tool in accordance with this invention 7 for bumping out metal.
Figure 2 is a front elevation of the tool of Fig. 1.
Figures 3, 4 and 5 are respectively sections on lines 3-3, 4-4 and 5-5 of Figure 1.
Figure 6 is a side elevation of a modified form of tool in accordance with this invention for bumping out metal.
Figure 7 is a rear elevation thereof.
Figures 8 and 9 are sections respectively 80 on lines 8--8 and 9-9 of Figure 6.
The tool illustrated in Figure 1 is termed a cowl post 5 con and comprises a handle 10 which may e of polygonal cross section to facilitate the firm gripping of the handle in the hand, and the handle may have any de-" sired length and at one end thereof terminates in a right angularly directed, curved coupling portioirll having a flared part 12 which v v merges into an'anvil 13 disposed substantially,
at right angles with respect to the coupling portion 11 and opposing the handle 10, as well as arranged in spaced relation with respect thereto.
The anvil 13 is preferably given the bladelike construction shown so that it may be inserted between the inner face of the sheet metal structure to be bumped out and an adjacent support or backing. frame, and the outer end of the anvil is preferably made quite thin to facilitate its insertion between contacting or closely adjacent surfaces. The thickness of the anvil may increase from its outer to its inner end as shown to impart to the anvil suflicienrstr'en'gth and stiffness to withstand the blows of the bumping-out hammer. The coupling portion 11 between the handle 10 and anvil 13 is sufliciently rigid to cause the blows delivered to the anvil to be directly imparted to the relatively heavy handle so that the weight of the entire tool will resist di lacement of the anvil under thehammer b ows, and as above stated the handle 10 is spaced from the anvil 13 a sufficient distance to clear a brace, beam or other structure which may occupy the space between the blade and handle during the bumpin'g-out operation. The construction of the entire tool is such that the handle 10 may readily be grasped in one hand to hold the blade 13 against the inner surface of the structure to be bumped out while blows are delivered by a hammer to the outer surface of the indented structure.
The anvil 18 illustrated gradually increases in width fromits inner toward its outer end whereby its outer end will be of greater width than its inner end. The outer corners of the anvil 13 are rounded as indicated at 14. The anvil 13 is disposed upon a slight inward curve whereby the free end thereof will project toward the handle 10. The outer face of the anvil 13 is of arcuate contour longitudinal] and transversely to present a curved sur ace to the metal to beumped out.
The tool as shown in Figure 6 is what is termed a single face spoon and comprises a polygonal handle 15 terminatin at one end in a substantially, ri ht angular y directed, curved tapered cou portion 16 which merges into a len hwise curved anvil 17 opposing and s ace from the handle 15. The outer face 0 the anvil 17 is of arcuate contour. The anvil 17 is upon a sli ht curve and is of less length than the han le 15 but of materially greater width than that of the lat- The'anv'il 17 is disposed substantially at ri t angles to the cou ling portion 16. The ree end of anvil '17 is directed toward handle 15. The handle 15 is not curved a*extends in the same plane throughout. The couplin ;.portion 16 is of the desired length so as'fl, ",r-maintain the anvil 17 an appropriate di na'nce from'the handle 15. The
inner face of the anvil 17 is flat and uninterrupted throughout and its outer face of arcuate curvature longitudinally and transversely. The anvil 17 gradually decreases in thickness from its inner towards its outer end and the major portion thereof is of uniform delivered directly to the handle. In the con-' struction shown in Fig. 1 the handle is made long as compared with the tool of Fig. 6 to increase the reach of the tool and the blade is comparatively thin, whereas in the tool of Fig. 6 the blade is relatively thick toward its rear end and blends into the curved coupling portion 16 to increase the rigidity of the entire tool. Each of the tools illustrated is so constructed that when the handle is grasped in the hand the anvil will lie opposite the hand in s aced relation thereto to facilitate holding t e anvil firmly against the work bein bumped out.
