COMBINED BLADING-TOOL .AND CIRCULAR SHEARS.

Specification of Letters Patent No. 5,994, dated January 2, 1849.-

To all 'whom may concern Be it known that I, JOSEPHF. li`LAi\n EEs,` of Newburyport, in the county of Essex andl lOf the said drawings Figure l, denotes a front elevation of my said machine; Fig. 2, an end elevation of it;,Fig. 3, a central, vertical, and transverse section of it; and Fig. 4, is a vertical and longitudinal section of it.

The first portion of my saidA machine consists of two frames A, and B, the` former of which is supported in a vertical position on a stand or pillar C, and so as to be capable of being freely revolved thereon, The latter is so hinged or jointed to the former byl hinges or joints as seen at a, b, as to be capable of being turned down into ahorizontal position or one at right angles'to that of the frame A. The inferior frame A, is provided with a rest bar, whose oiiice is to support the inferior die holder or holders,jthe

same being seen at c, d, e. The superior frame B, is also provided with a rest bar f, the purpose of which is to carry and Sustain the superior die holders g, L. Each of the said die holders should be so adapted to its bar, as to be capable of being readily adjusted to such position thereon as may be desirable. For this purpose each rest bar on each side of the middle part thereof has a long vertical Slot I, made through it, the

'said slot being extended nearly to the outer end of the bar. A screw pin 7c, projects from each holder, passes through the slot in the rest bar, and has a confining nut Z, on its end which extends beyond the bar, the said nut being caused to act against a washer m, previously placed on the screw pin and made to act against the bar. vBy such contrivances the die holders may be adjusted to any desirable positions with respect to each other.

rIhe superior frame B, is provided. with two spring latches D, E, made and applied to it and the inferior frame as represented in the drawings. Each latch acts in concert with two projections 0, p, one of which` is made to extend froml the upper frame B,

while the other projects from the lower frame A, as seen in Fig. 2. When brought together ythe notch g of the spring latch receives them, and by so doing preserves the two frames inv a vertical plane during the cutting operation. The spindle or pillar C,

which supports the inferior frame A, is made tubular, and receives the shank 7', of a tablet or jaw F, arranged as seen in the drawings.

Directly over the said jaw or tablet is another andsimilar one Gr,-which is fixed to the superior frame'B, and in such manner as to revolve freely thereon, or to allow the said frame to be revolved in a horizontal direction in the shank of the jaw. The lower jaw. is to be raised up against the upper one lso as to enable aperson to confine a plate of tin.or other material between them while being operated on by the dies. The shank r, of the lower jaw rests on one arm of alever s, the said arm of the said lever being caused to project into the standard, while the other arm extends beyond or out of it, and has a confining spring latch t, connected with Yit for the purpose of preserving it in any de.

sirable position, the yfulcrum ofthe lever being at u. VBy depressing the outer arm of the lever we elevate the inner arm of it, and

thereby move the lower aw or tablet up toward the upper one, and so as to confine in position any sheet of tin, which may be placed between said jaws.

The dies or cutters-for cutting a circular path through a plate of metal consist'of a f horizontal circular wheel I', and' a vertical wheel K, each being made to revolve within its supports or holders. One side of the upf per. wheel K, is placed in .contact withA the periphery of the wheel I, and so that the pe-A riphery of the said wheel K, shall extend a very short distance below .the horizontal upper surface of the wheel I. The two dies Y L, M, seen n the drawings and arranged on the other side of the holding'jaws are what' may be termed beading dies. y consist of two vert-ical wheels the lower one and around its periphery, while the upper has a projecting bead c, which is made to rllhey i u, y of which has a crease or groove extending in j '1 tion of cutting a circular plate or space n i' from a sheet of tin, and of beading it in at the same time is as follows. The superior frame B, being turned down into a horizontal position a plate of tin is laid on the lower jaw F, and the lower cut-ting die I, and if desirable to make at the same time a circular bead on the plate, the said plate is also laid on the lower beading die. This being accomplished the superior frame B, is turned up into a vertical position. the periphery or edge of the' superior cutting wheel K, is forced down through' the tin plate. forced into the plate. Next the lower jaw F, is elevated against the plate, and so as to confine the plate between it and the upper jaw, and prevent it from slipping laterally or revolving during the operation of cutting or beading. The whole being t-hus arranged the frames and dies are to be revolved in a horizontal direction around their supporting spindle. While so doing the cutting dies will cut a. circular path throughthev tin plate. The beading dies will at the same time produce a bead on the plate or on thecircular piece removed from it, according as they are set without or within the circle of eut of the cutting dies.

A rod or arm P, projects rearward from the upper frame B, as seen in the drawings. From said arm a gage rod Q, depends, and is so applied to the arm by a slideA and a clamping screw y, as to be capable Vof being slid or moved on the arm and confined in any desirable position thereon. Said gage rod extends down below the pla-ne of junction of the jaws F, G. In cutting circular plates from a st-rip of metal the said strip In doing thisl The upper beading die Vis also' is moved over the lower clamping jaw, until it abuts against the gage rod which being previously set in the right position serves to X the position of the strip of tin pre- -vious to thev removal of each circular plate ordisk therefrom.

ByV my improved 4mode of making the frame which sustains the" cutting wheels their operation may be commenced in any part of the circular path tobe lcut through a plate; for by making the frame 1(0f two frames) A, B, hinged together, and carryingthe cuttingtools or dies as above specified, the upper cutting dies may bereadily forced down through the plate resting on the lower dies and this before the dies are rotated and madey to cut in a circular path.

In lieu of the beading dies, such as will turn f down the edge of the plate at anvangle with the remainder of it may be used.

VVhat I claim as my invention, is-

The combination in one frame constructed as described, of a set of cutting dies and one or more sets of beadingor edging dies, so applied together, and tothe frame as to permit of the easy insertion' of the plate, the commencement of the cut on any part of it, and soV that the plate or sheet of met-al may be ,operated upon simultaneously by both beading and cutting dies when frameqis revolved on its spindle.

In testimony whereof I have hereto set my signature this fourth day of September,

A. D. 184s.-
