11,501,388 W. J. BAKER DEVICE `FCR FCRMING METALLIC OBJECTS Filed' `May 5, 1922 wi am m @MYI mmm J. 27d/fer Fatented July l5, 1924.
WILLIAM J- BAKER, OF ,NEWEORT KENUUCKY- nEvrcE non. lnoruf/ rrive METALLIC planners.
AApplication filed May 5,
To all whom it may concern.'
Be it known that I, lVILLmM J. BAKER, a citizen of the United States of America, and a resident of Newport, in the county of Campbell and State of Kentucky, have invented new and useful Improvements in Devices for Forming Metallic Objects, of
which the following' is a specification.
My invention relates to a device for forming objects such as frames for toy tennis rackets, etc.
An object of my invention is to provide a device for the purpose stated which is adapted to give a smooth and even shape and contour to such objects.
Another object of my invention is to provide a simple and efficient device of this kind.
These and other objects are obtained by means described herein and disclosed in the accompanying drawing, in which:
Figure 1 is a plan view of a device embodying my invention.
Fig. 2 is a sectional view on line 2 2 of Fig. 1.
Fig. 3 is a perspective view of the type of material generally worked upon by de vices of the nature. described in this application.
Fig. 4 is a perspective view of an article formed on a device embodying my inven-/ tion.
The device of my invention embodies a platform or base 5, upon which is mounted a form or pattern 6. In the drawings the pattern is such as is used toform a frame for toy tennis rackets. The pattern is supported above the platform 5 by means of a block 7 and the levers 8 and 9 are pivotally mounted on theA pin 10 extending upwardly from the base 5. A track or frame is mounted on the base and extends about the enlarged portion or head of the pattern 6, said track comprising the strips or blocks 11, 12, 13 and 14. The levers each carry a roller 15 spaced from the pattern 6 at a distance substantially equal to the thickness of the material 16 which is to be formed. The levers also carry blocks 17 which are adapted to engage the metallic strip 16 and to cooperate with the rollers in bending or forming strips 16 about the pattern. The levers engage the strips 11, 12, 13 and 14, said strips serving to support the levers at places intermediate the 192,2. sena; No. 558,775.
ends of the lever. A stop plate 18 is mounted on the base and has an upwardly eX- tending flange 19 which limits the backward movement to the levers beyond the center line of the pattern.
The operation of my device is as follows:
The levers 8 cind 9 are moved to the positions shown in Fig. 1 and a strip 16 is inserted between the rollers .15 and the pattern 6, the ends of the strip resting upon the strips 11 and 14. The levers 8 and 9 are then moved about the pivot 10, thereby causing the rollers to bend and form the strip 16 about the pattern as shown in dotted lines A. As the levers are moved about their pivotal mounting, the'blocks 17 are brought into engagement with the ends of the strip 16, and form the eXtreme ends of the strip 16 about the reduced portion 20 of the pattern 6. The free ends of the blocks 17 are given a form complementary to the reduced portion of the attern 6, in order that 'the block 17 may form the eX- treme ends of the strip 16 about the reduced portion of the pattern 6 as shown in dotted lines B. After the strip 16 is given the desired form the levers are. moved to the positions shown in full lines in Fig. 1, whereupon the frame 21 of the toy racket is removed from about the pattern. The block 7 besides serving as a support for the reduced end of the pattern, is also adapted to support the free ends of the blocks 17 at the time when the blocks 17 come into engagement with the strips 16 from which the frame 21 is being formed. It should be further observed that strip 16 is supported at its eXtreme ends by the members 11 and 14 until such time that said ends are immediately adjacent the block 7, said block serving to support the ends of the strip as the ends of the strip are moved toward the reduced portion of the pattern.
That I claim is:
1. In a device o f the class described, the combination of a base, a pattern mounted on the base, a track extending about the pattern, levers pivotally mounted between the base and the pattern, rollers mounted on the levers and spaced from the pattern at a distance substantially equal to the thickness of the material to be formed about the pattern, the levers being adapted to be moved about their pivotal mountings whereby to cause the rollers to be moved about thepatt-ern, the track being adapted to support tlie levers and the material to be formed.
2. In a device of the class described the combination With a base., of a pattern mounted on the base and having-in part a circular form, a. lever pivotally mounted on the axis of the circular portion of tlie pattern, a roller carried by the lever and l0 spaced from the pattern at a distance substantially equal to the thickness of the. material to be formed about the pattern, means to support a Vmaterial to be formed about the pattern, and means tixedly mounted on the lever adapted to form the material about the non-circular portion of the pattern.
In testimony whereof, I have hereunto subscribed my name this 4th day of May. 1922.
