Description
tinted sans @stent JOHN DAWSON JAMES, JRmOF WASHINGTON, DISTRICT OIv COLUMBIA, ASSIGNOR TO HIMSELF, ADOLF BODE, AND JACOB- C. OUTWATER, OF NElVARK,` NEW JERSEY.
Leners Patent N 100,413, dared March 1, 1870.
IM'PROVEMNT IN TINWORKERS TONGS.
'l'he Schedule. referred to itx/these Letters Patent and making part of the same.
To allwhom @t may concern:
Be it known that I, JOHN DAwsoN J AMES; Jr., of
Washington city, and District ot' Columbia, have in` vented certain new and useful Improvements'in Tin- Workers Tongs; and Iv do hereby declare that the fo lowing is a full, clear, and exact description of the same, reference heilig had to the accompanying draw- `ing and'to the letters of reference marked thereon,
herewith, is to facilitate the operation of tin rooiing,:
dispensing as it doeswth the tedious work with grooving-iron and.mal1et, as no'w practiced.-
The nature of my invention consists in so forming the jaws of the tongs that when they are applied to the seams of the sheets ot' tin or other roofing material, the same having been previonslymade or thrown up'vertically by the ordinary tongs now in general use, the projecting poltion of the longest seam shall be forced down horizontally with the roof, or at rightanglesto the short seam and the main sect-ion of the long seam, and in the desired and proper position 4to he pressed down by the mallet, or for the action 0i' my improved swage, which forms the seam-joint.
,To enable `others skilled in the art to make. and use my invention, I will now proceed to describe its construction and operation.
A A' are the levers or handles, and are pivoted at a.
B B are the jaws, and are connected to the leversy A A in the usual manner. These tongs may he cast or made in anyl other ordinary manner, and of any suitable metal.
C is a. guide or check-plate, and is cast with the jawI B, or otherwiseattached thereto. This plate C actsv as a projecting lip or flange on the jaw, serving, when the tongs are in use, to prevent their coming .in contact with the roof', in order thatthey may properly work the seam, and to assist in forming the double seam-joint. The form of these jaws is clearly shown in the drawing,-B heilig recessed, and B having a solid l projecting head or face, the contour' of which corres.
ponds exactly with the recess, so that when the jaws are broughttogether the head fit-s exactly in the re cess, only leaving a space between the two sutiicieut forthe thickness of' the metal to be worked. \Vhen the tongs are applied to the metal seams, it gives to the saine by its pressure exactly-the shape or forni shown in outline by b b.
Having thus fully described my invention,
XVhat'I 'claim therein as new, and desire tosceure by Letters Patent of the.United States, is
The levers A A aws B l and ruide or checkplate C, when the same are constructed, combined, and arranged as described.
4In testimony whereof I have signed my name to this specification in the presence of' two subscribing wit nesses.
