IMPEOIIEDl DIES EOE HEADING Eems.-

TO ALL WIIOM IT MAY CONCERN: A
Be it known that I, WILLIAM J. LEWIS', of Pittsburg, in the county o Allegheny, and State of Pennsylvenia, have invented a new and useful Improvement in Heading,r Dies; and I hereby declare that the followingVV is a full, clear, andexact deseription'of their construction and operation, reference being had to the accompany-- ing drawings, forming,r part of this specitication, and to the letters of reference-marked thereon.
The nature of my invention consists in.such format-ion ofthe dies as' that the' head ofthe bolt will be embraced by the closing of the gripers on four sides of a hexagon, leaving the two remaining sides open, to alloIvl .the surplus metal to be forced out in that direction by the action of the heading-die, and as the dies open preparatory to another stroke, theV bolt, on being` turned one-sixth way round, will bring .the metal that' was driven out at the open space against a solid portion ot' the dies, which, on the closing of the dies a' second time, will force the projecting metal into the-body of the head, while the overlapping ot the header in the space between the gripers, drives in the Hash or nf or thin sheet of metal that would otherwise be left on the head.
To enable others to understand and make Iny improvement, I will proceed to describe the construction or shape et' 'the dies, by reference to the accompanying drawings, wherein- Figure 1 represents a perspective view ot` the front or operating ends ot' the header and gripng-diesA Figure 2 represents the back ot' the gripers, as seen when closed.
Figure 3 is a front view et' the same.
Figure 4 represents a top view ot' all the` dies,
The various drawings"are'lettered, and similar let-ters denote the saine parts in the several views.
I construct my machine for operating the dies in any of the well-known Ways, and in precisely the same manner as those 1for which a patent was granted to ine on the fifteenth day ci March, 1864, But in order to eicct the result hereinbefore mentioned, instead of the inside of the griping-dies B B being perfectly plain, I have cut an angular groove, S, in the face oIn each, which is intended to give form to the head, while the surplus metal is forced out in the space C C, made by cutting away a portion of the gripingdies B B at the top and bottom, equal to two sides ofthe hexagon. The header A has, on each side, an angular projection, N, as shown at fig., I, corresponding in shape with-the recesses S, cnt in the gripers, while the central verticai parts L L exactly iill the space C, and overlap the edges of the bolt-head in a manner that drives in the flash orfn on the turning of the bolt.,
I claim constructing the dies B B and header A, as hcreinbefore described, so that .said dieswill embrace four sides ot` the bolt-head, and leave two openings t'or the two remaining sides, and space for the surplus iron, said dies and header being so arranged with relation to eachother, that by turning the bolt one-.sixth way round,
Vthe surplus iron and the Hash or iin will be brought in contactwith a solid portion of said-dies and header,
and thereby be driven into the head of the bolt, substantially as herein described and fertile purpose set forth.
' WM. I; LEWIS.
