MACHINE FOR SWAGING SHOE-TIPS.

Specification forming part of Letters Patent No. 28,888, dated June 26, 1860; Reis-sued June 16,

186s, No. 1,500. x

To all whom it 'may concern:

Be it known that I, GEORGE A. MITCHELL, of Turner, in the county of Androscoggin and State of Maine, have invented a new and useful Machine for Swaging or Shap ing Boot and Shoe Tips from Blanks of Sheet Metal; and I hereby declare that the follow-ing specilication, in Vconnection with the accompanying drawings and references marked thereon, constitute a lucid, clear, and exact description of the construction and use of the same.

Referring to said drawings, Figure l, denotes a plan or top view. Fig. 2, a side elevation. Fig. 3, a central and vertical section on line A, B, of Fig. l, and showing parts beyond. Fig. 4, an end elevation of it. Fig. 5, denotes a blank ready for swaging, and Fig. G, denotes the same blank after being swaged, or made into the tip by my ma chine.

Invention-The nature of my invention consists of the die box die, plunger and guide, so arranged and operated in relation to each other that flat sheet metal blanks, or other substance are instantly formed into the required shape to conjoin with the toe of the boot or shoe and constitute a protecting tip, all as will be hereafter seen.

Construction-To enable persons skilled in the art to which my invention appertains to construct and carry out the same I will describe it as follows.

I construct a platform of wood, seen at A, in which is firmly framed two posts, seen at B, and united near the top by cross bar C. A suitable block, seen at D, is firmly secured to posts B, to the top of which is secured the die holder E, made of iron and provided with screws F, passing through each of its four sides, for holding the die G, therein, and in any desired position.

Two iron ways or tracks seen at H are secured to the posts B, and in which a metal plunger` I, is fitted to freely drop slide and be guided therein to correctly direct the follower J, to, and into the die G. This follower is rmly secured to the plunger I, by its upper end being dovetailed to the lips a, thereof and stopped by ledge c, all of which are cast on, and withplunger I. The lower end of follower J, is shaped exactly of the desired form to be given the tip, and then the same is impressed into a pattern or mold, and then .the die G, is cast therein, leaving the cavity in it just as large as the follower. Then the follower is finished down or reduced in surface the thickness of the plate for the tip.

I now form a guide, seen at K, which is secured to the die G, by screws z'. This guide has a slot cut through it, the lower portion being the same shape and size of the portion of the metal plate which is to form the upper part of the tip, when applied, and completed. This slot is longer than the cavity in the die, its edge corresponding with, but receding a little from the cavity quite around its surface, so that when the metal plates are cut of the shape as seen at Fig. 5, and so that their rounding surface will just fit into slot in guide K, the follower J, by an instantaneous dro-p or movement will by its plunger I, form this metal plate seen at Fig. 5, into a tip, seen at Fig. G, (and patented to me Jan.5, and Dec-7, 1858,) so as to need no trimming, so far as shape is concerned. The inner upper corner must be rounded to prevent its wearing the Lipper leather, and this is done by tumbling 7 them in a rolling cask with saw dust, or any other suitable substance.

USc.-Tlie use of my invention is obvious from the description of its construction.

The handle L, of plunger I, is seized by thev hands of the operator, and raised until it pinches and is held up by pin L, passing up into tapering slot N, and impinging against its sides. The blank seen at Fig. 5, is then placed in the guide K, and above the die G, and the pin L, is then seized and brought down, with plunger I, and follower J, with a blow which instantly forms the tip, as seen at Fig. G.

What I claim as my invention and desire to secure by Letters Patent is The combination of the die G, guide K, die box or holder E, and follower J, arranged and operated in the specific manner described, and for the specific purpose fully set forth and described.
