Specification of Letters Patent.
Patented Feb. 8, 1921.
Original application filed March 29, 1919, Serial No. 286,192. Divided and this application filed September 4, 1919. Serial No. 321,544.
from the fenders, door panels, tonneaus,
cowls or other sheet metal parts of vehicles and the like, without injury to the paint or enamel.
The subje t-matter of this application has been divided out from my co-pending application forimprovements in metal working tools. filed March 29, 1919, Serial No. 286,192. patent issued September 16, 1919, No. 1,316,451. r
According to the present practice whenever a fender or other sheet metal part of an 7 automobile is bent or damaged in any manner, the indentation is removed by a process known as hand-peening. This process consists in placing a templet under the damaged part of the sheet metal and pounding upon the other surface thereof with a ham mer. This cracks the enamel, and, while the surface may be entirely smooth when the job is finished, yet this hand-peening is a long and laborious task. Usually the damaged fender or other sheet metal part of an automobile is removed and the work done in the shop. with the result that several hours of time is required and the owner is put to a considerable amount of expense. According to the present invention, the bumps or indentations can bebent back into place without hand-peening andan approximately smooth surface obtained, after which the ironing or shaping rollers disclosed-in my co-pending application can be used, if necessary, to remove the unevenness that may still remain and produce. an absolutely smooth and finished surface. Repairs of this kind can be readily made Without any considerable loss of time and at a minimum expense.
' With these and other objects in view, the
invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.
For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in which:
Figure 1 is a side elevation of the tongs or U-shaped frame which is provided for carrying the sheet metal shaping elements, one set of the said elements being indicated by dotted lines, and a portion of the tongs being broken away to show one of the slips in the arms thereof;
Fig. 2 is an end view of the tool with a set of shaping elements carried thereby, said tool being shown as applied to an indented sheet metal article and in the position assumed preparatory to manipulating the tool to bend the dented; portion of the sheet metal article back into shape, said sheet metal article being shown in section;
Fig. 3 is a perspective view showing the tool as applied to an indented portion of. an automobile fender, the said fender being shown in section;
Fig. 4: is a sectional view through the two arms of the U-shaped frame or tongs, showing the T-headed clamping bolt which is used for swinging the arms of the frame toward each other, a portion of the bolt being broken away;
Fig. 5 is an end view of the U-shaped frame or tongs, showing the hinge structure at the closed end thereof;
Fig, 6 is a detail view of one of the pressure feet which is used in connection with the transverse pressure bar shown by Fig. 2 Figs. 7 and 8 are detail views showing another form of stake head which is of an elongated formation; and,
Fig. 9 is a detail View of a roller attachment which may be substituted for one of the stake heads, if desired.
Corresponding and like parts are referred to in the following description and. indieated in all the views of the drawing by the same reference characters.
In the particular embodiment of the in-- vention illustrated by the drawing, the main frame has a substantially U-shaped formation and. includes two corresponding and upon the U-shaped frame.
opposed arms 1 and 2 which are hingedly connected to each other at the curved or closed end of the U-shaped frame, as indicated at 3. The two frame elements or arms 1 and 2 are each longitudinallv slotted, as indicated at 4, to receive a clamping bolt5.
This bolt has a T-shaped head 6 which isv adapted to engage any selected one of a series of notches or serrations 7 in the frame member 2, and which will move freely through the slot 4 of the frame member 2 when it is disengaged from the said notches and turned into alinement with the slot. The free end of the clamping bolt 5 is threaded to receive a nut 8, said nut being formed with a lateral handle 9 by means of which it can be readily rotated. A flanged washer 10 is fitted upon the clamping bolt 5 under the nut 8 and rests upon the frame member or arm 2 when in operative position. It will be obvious that this T headed clamping bolt can be quickly placed in position or removed therefrom and that it c: n be readily adjusted in the slots 4 and positioned at any desired point After "the bolt has thus been properly positioned the arms 1 and 2 of the U-shaped frame can be swung forcibly toward each other by manipulating the handle 9 and screwing the nut 8 downwardly upon the bolt.
The extremities of the hinged frame or tongue members 1 and 2 are formed with tapered sockets 11 which detachably receive correspondingly formed tenons 12 of the pressure and shaping elements. The tapered formation of the tenons enables different sizes and forms of pressure and shaping. elements to be used interchangeably with each other, and to be easily detached from the frame by tapping thereon. In Figs. 2 and 3 the tool is illustrated as applied to a sheet metal fender A' for the purpose of pressing out a large dent B .therein.
A pair of pressure feet 13 engage the fender A on opposite sides of the indented portion 13 thereof, said pressure feet being provided with eyes l'which are loosely received bythe arms or reduced ends 15 of a transversely disposed pressure bar 16. The middle portion of thepressure bar is shown as slightly enlarged and provided'with av-tenon 12 which is received within the socket 11 of the upper frame member or arm 1 of the U- shaped frame. The eyes 14 are looseupon the arms 15 of the transverse pressure bar so that the pressure feet .13 can be moved toward or away from each other, as may be desired, and are freetohave the limited tilting or rocking movement which may be necessary to seat themselves properly upon the curved surface of a sheet metal article such as an Heads 17 at the ends of the arms 15 retain the eyes-14 upon the transverse pressure bar and prevent the pressure feet 13 from becoming disengaged therefrom. Thelower faces. of the pressure feet 13 may be slightly concave so as to conform to the curvature of a crown fender or like article, and may have a protective covering 18 of rubber or like material applied thereto so that there will be no danger of scratching or marring the paint or enamel by the application of the pressure feet thereto.
The lower arm or frame member 2-is provided with a suitable shaping element such as the large stake head 19. As shown by Figs. 2 and 3 this large stake head is substantially semi-spherical in shape, although it will be obvious that different sizes and shapes of stake heads may be used interchangeably, depending upon the size of the indentation B in the fender, and also upon the character of the article being worked upon. The base of the stake head is formed with a tenon 12 which is removably received within the socket 11 of the lower frame member 2. This stake head 19 is brought into engagement with the convex side of the indentation B, as indicated by Fig. 3, after which the handle 9 is manipulated to screw the nut 8 down upon the clamping bolt and forcibly move the members land 2 of the U-shaped frame toward each other. The stake head will then operate to press out the dent B, and the U-shaped supporting frame can be manually manipulated in all directions to assist in-bending and straightening out the sheet metal in the necessary and proper manner. This manual manipulation ofthe U-shaped supporting frame in varying directions enables the pressure to be distributed in the desired manner so that the indented portion of the metal can be bent approximately back into its original shape without difficulty and the tool maintained under proper control, as the clampingbolt is tightened and the operation proceeds. With the arrangement of shaping elements shown by Figs. 2 and 3 the concave side of the indentation B is straddled by the pressure feet 13 and the 2 and 3, and in Figs. 7 and 8 I have illus trated a stake head 20 which has an elon: gated formation, and which may be used to advantage under certain conditions, different types of shaping and forming'ele- .ments being necessary for work upon different styles of fendersand other sheet metal automobile parts. Under similar conjzlitions,
it may be also desirable to substitute a forming element such as the roller 21 for one of the stake heads. This roller 21,. which is shown by Fig. 9, is journaled between the arms of a forked frame 22, said framebeing formed with a tenon 12 which will fit in either one of the sockets 11. This roller could be substituted for the stake head 19 in the arrangement illustrated by Fig. 2..
vIn the operation of the tool, if it is desired to remove a dent from an automobile fender or other sheet metal article, the parts may be assembled in the manner indicated by Figs. 2 and 3. The stake head or other forming element corresponding to the stake head is brought forcibly into engagement with the convex side of the indentation B and the tool manipulated in an up and down direction or upwardly and downwardly oscillated as the nut 8 is screwed down on the clamping bolt 5, thereby bending the indented portion of the sheet metal fender back to approximately its original shape.
If it is desired to completely iron out all of the minute irregularities in the sheet metal article and leave an absolutely smooth and finished surface, the operation-may be completed by using the shaping and forming rollers which are disclosed in my before-mentioned co-pending application, SerialNumber 286,192, patent issued September 16, 1919, No. 1,316,451.
lVhile I have specifically described my invention with reference to the particular embodiments thereof which are illustrated by the drawing, it will be understood that the principle of the invention is susceptible of being used for removing indentations or unevenness from any sheet metal surface, and that the details of the invention can be modified in various manners within the scope of the appended claims, without departing from the spirit of the invention or sacrificing the advantages thereof.
