The present invention relates to metal shaping tools or machines and more particularly to a device for the shaping or re-shaping of fenders or the like.

An object of this invention is to provide a sheet metal shaping means which has been particularly designed for the purpose of ire-forming or reshaping fenders, the device embodying means whereby the metal may be re-shaped on a straight line or on a curve.

Another object of this invention is to provide a device of this kind which is so constructed that it can be used with fenders having a relatively deep side flange, the device being capable 1 of re-shaping the inner portions of the fender and eliminating the necessity of hammering or otherwise forcing out dents or the like in fenders.

The above and various other objects and advantages of this invention will in part be described and in part be understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawings wherein:

Figure 1 is a detail front elevation of a device constructed according to the preferred em. bodiment of this invention, showing the pair of bending rollers in operative position.

Figure 2 is a similar view with a part of the front frame removed and showing the bending rollers in another position.

Figure 3 is a sectional view taken on the line 3-3 of Figure 1.

Figure 4 is a detail side elevation partly in section and taken substantially on the line 4--4 of Figure 1.

Referring to the drawings wherein like numerals of reference designate corresponding parts throughout the several views, the numeral 10 designates generally a frame structure which is substantially T-shaped in transverse section and provided adjacent the upper portion thereof with a hand grip 13. This frame 10 comprises an upper leg 11, a vertical leg 12, and a third leg 14, which is positioned on an acute angle to the vertical leg 12 and extends in the direction of the upper leg 11. The lower leg lei terminates at its upper end in a pair of spaced ears 15 between which a shaping roller 15 is rotatably mounted. The shaping roller 16 is mounted on a pivot 17 engaging the spaced ears 15. The peripheral surface of the fixed roller 16, in'the present instance, is convex so that this roller may engage the concave under surfaces of a fender or the like. A vertically disposed guide 18 is secured to the forward end of the upper armor frame member 11 and is also secured to the forward end of the hand grip 13. The guide 18 extends longitudinally of the frame 10, the purpose for which will be hereinafter described. In the present instance, these frame members are formed integral one with another so that a relatively strong frame will be provided. The guide member 18 has a flat front face end the vertical edges of this guide member 18 may be either square or V-shaped, depending only upon the type of guide which may be desired.

A slide or carriage, generally designated as 19, slidably engages the guide 18 and is movable longitudinally of the frame 10, and is adapted to be held in adjusted position on the guide 18 by means of a hand operated screw 20 having a wheel or operating member 21 secured thereto. The upper end of the carriage 19 is provided with a rearwardly extending lug 22 through which the screw 20 projects, and the screw 21) is rotatably mounted in this lug 22 so that as the screw 29 moves relative to the guide member 13, the screw 20 will carry therewith the carriage 19.

A pair of rollers 23 and 24 are rotatably carried by a yoke 25, which is swingably mounted on a pivot 26 secured to the carriage 19 adjacent the lower edge thereof. These rollers 23 and 24 are positioned for coacting relation with the lower roller 16, and when it is desired to re-shape sheet metal or the like, these rollers 23 and 24 may be positioned with the axial center thereof on opposite sides of the axial center of the lower roller 16. The axial center of the lower roller 16 is disposed substantially coplanar with the longitudinal axis of the frame 10. The length of the frame 10 is shown in Figures 1 and 2 and the longitudinal axis is a line drawn vertically through the frame, as disclosed in Figures 1 and 2.

An arm 2'? integral with the yoke 25 and extends along the front face of the carriage 19. This arm comprises a means whereby the two rollers 23 and 24 may be held in laterally adjusted position relative to the lower roller 16, and in order to hold the rollers 23 and 24: in adjusted position on the pivot 26, I have provided a holding member in the form of a bar 28, which is secured. to a pin 29. The pivot or pin 29 is pivotally secured to the upper end of a bracing frame 30, which comprises a substantially iJ-shaped upper portion 31 and a V-shaped lower portion 32, which is integrai with the upper portion 31.

The frame 30 is mounted on outstanding pins or posts 33, there being one post on each side of the carriage l9, and the convergent end of the frame 30 engages the post or pin 26 and holds the yoke 25 against longitudinal movement on this post 26. The pin 29 has a bar 34 extending transversely therethrough which constitutes an operating member so that the holding member 28 may be swung to the desired position. The frame 30 is cut out, as at 35, and the pivotal pin 29 is provided with a stop 36 engaging in the cut out portion or notch 35, thereby limiting the swinging movement of the holding member 28.

In the use and operation of this device, the frame 10, which has the arms 12 and 14 positioned on an acute angle, is adapted to be disposed with the roller 16 on the lower side of the fender and the two rollers 23 and 24 on the upper side. Turning of the hand wheel 21 will adjust the rollers 23 and 24 relative to the lower roller 16, so that this lower roller 16 will press the metal between the two rollers 23 and 24. The handle or grip l3 and the lower end of the frame 10 can then be grasped and the device rolled over the fender or metal, which operation will act to bend the metal on an are.

If it is desired to straighten the metal, the position of the frame can be reversed with the two rollers 23 and 24 engaging on the concave side of the metal and the roller 16 on the convex side. The foregoing procedure will apply to sheet metal such as fenders or the like, where it is desired to roll the metal on a curvature, and in order to do this, the two rollers 23 and 24 will be in the position shown in Figure 1, namely, on opposite sides of the axial center of the lower roller 16.

However, where it is desired to shape the metal without bending it on a curvature, the arm 27 can be swung to the opposite side of the carriage 19 or, in the present instance, to the left, which movement will swing the yoke 25 and raise the roller 24 while lowering the roller 23 into a position substantially with the axial center thereof alining with the axial center of the lower roller 16 and with the longitudinal axis of the frame 10. In this position, the two rollers can be engaged with the metal and slight dents or the like can be removed from the metal or the metal otherwise re-formed and the roller 24 will be disposed in inoperative position laterally of the longitudinal axis of the frame 10.

By providing a carriage operating member in the form of a screw 20 which is threaded into the frame 10 and which swively engages the carriage 19, this carriage 19 can be adjusted to any desired position relative to the lower roller 16 and the carriage will be locked in its adjusted position. By providing at least three rollers, two of which are mounted on the carriage, which can be adjusted to any desired position relative to the fixed or lower roller, the metal can be re-formed without pounding and the surface of the metal is, therefore, left smooth when the metal has been reshaped. Preferably, the rollers 23 and 24 are constructed with a fiat peripheral surface although I, of course, do not wish to be limited to the particular shape of these rollers 23, 24 and 16, as they may be of any other configuration, depending only upon the character of metal which it is desired to work upon and the configuration which it is desired to form from the metal.

It is, of course, imderstood that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.
