To all whom, it may concern:

Be it known that I, ROBERT An'rnonr HARD CASTLE, a subject of the Queen of Great Britain and Ireland,residing at Leeds, in the county of York, Kingdom of Great Britain and Ireland, have invented new and useful-Improvements in Machinery or Apparatus for Punch ing, Embossing, or Shearing Metallic=Plates, of which the following is a specification.

Thisinvention relatestoamachineforpunehing and embossing or shearing metallic plates of various kinds for various purposes,and may be used with advantage to perforate and emboss boiler-plates to receive tubes or stays. Themaehinecomprisesupperandlowerbeds or gauntries rigidlyconnected together,with a space between them, a saddle able to slide on he cylinder on one saddle,with ram that carries one die or part die or tool, the corresponding die or part die or tool being mounted on the other saddle, and meanswhere by-said saddles can be traversed simultaneously or otherwise along their respective beds or gauntries.

Figure 1 of the annexed drawings is a sectional elevation of the machine; Fig. 2,an end elevation.

A is a lower bed or gauntry; A, an upper one. They are shown as made of I malleable but, if desired, may be of other material or construction. Between these, at the ends, are columnsor uprights B B, the whole being bound firmly together by bolts 0 O O O, as shown,or in any equivalent manner.

D is a saddle on the under side of the upper gauntry, A, to whichis fixed a suitable tool, as shown. This tool is a cupped die or matrix, E, such as described and claimed in my other specification of same date for Letters Patent of the United States, Serial N 0. 206,569, filed June 29, 1886.

F is a saddle on the lower bed or gauntry, A. This carries in the example illustrateda hydraulic cylinder, G, and ram H. (The saddle F and cylinder G may be in one piece, if desired.) On the rain H is or are mounted a tool or part or part-s corresponding to that or those on saddle D. As illustrated, there is a. flat-ended punch, Lwith its hub or carrier 1, as described and claimed in my other specification above referred to.

It will be evident the arrangement might be reversed, the cylinder and ram being then carried by saddle D.

The two saddles D and F are capable of movement along their respective beds when operated by means of screws D and F, respectivcly, andgcar-wheels D and F, which are connected by means of the intermediate gearwheel, J, to which is attached the handle J,

so that the two saddles with the tools can be moved simultaneously along the gauntries A and A to suit the positions of the requiredembossments or operations on a plate under treatment. When it is required to change or adjust the tools, the intermediate wheel, J, is moved out of gear with the wheels D and F, so that the screws D and F can be moved independently of each other for the adjustment or change required, after which the wheel J may be replaced into gear with wheels D and F K is a spiral spring connected to the cylinder G by the rod K, for accelerating the recession of the ram H, (after effecting an embossmeut.) Said rain is made hollow to admit the said spring and rod, and is provided with a plate, I-I,at its lower end for thespring K to act upon while returning the plunger or ram, the upper end of the spring taking a hearing against the nut K on the rod K.

If the saddles be connected with the punches and the embossing-matrix or other tools coaxial, the two saddles can evidently be simultaneousl y moved along their respective beds or gauntries by means of the screws and gearing provided for the purpose, so that they can be traversed from one end of the machine to the OlhGI lllil-l) is to say,acrossaplate under treatment--thus commanding allsuch parts of such platein the direction of the required line of embossnionts or other operations,and the plate can be moved longitudinally to bring it into position for each embossment or other operation by hand or otherwise.

In adjusting the tools to each other, or in changing or replacing either of them, the abovedescribed saddles may be disengaged from each other, moved separately, and afterward be reconnected. For actuating the hydraulic ram in the direction required for punchi ng,embossmg, or shearing, either an accumulator or a ICO hand or power hydraulic pump may be employed, the recession of the ram after each forward stroke being effected by the recoil of the Spring.

The punchesand dies or other tools may be applied either singly or otherwise, so as at one operation to produce either one or a series of holes and cmbossments or other work.

If an ordinary punch and die be substituted {or the embossing punch and matrix, the machine will do ordinary punching, the pitch of v the holes produced being determined by the traverse screws and gearing in connection with she movable saddles. If shear-blades be used,

I c' the machine can be employed for trimming the edges or otherwise parting of plates.

What I elain'i is- 1. A machine for punching, emhossing, or shearing metallic plates, comprising in combination an upper and a lower bed or ganntry, connected together so as to form a compact frame-work, a movable saddle on each bed or ganntry, means for moving them simultaneously or separately,

ble saddles ahydraulic cylinder and a ram on which can be mounted required tools,whereby the said cylinder and ram are movable to any point within the range of the machine, substantially'as described, and for the purpose specified.

l l \connected together so as and on one of said mova- 2. A machine for punching, embossing, or shearing metallic plates,comprising an rnper anda lower bed or gauntry,connected together so as to form a compact frame-work, a saddle on each bed or gauntry, a hydraulic cylinder and ram, and a spiral spring within said hy: draulic cylinder and ram for causing the :sapio recession of said ram after a punching, em bossing, or shearing has been effected, sul stantially as described.

3. A machine for punching, embossing, or shearing metallic plates, comprising in combination an upper and a lower bed or gauntry, to form a co npaet frame-work, a sliding saddle on each bed or gauntry,thc screws and gears for moving said. saddles along said beds or gauntries, and ah 1 draulic cylinder and ram carried by one of sat-'1 saddles,whereby the line of action of the tool or tools is'always on the center of said cylinder, substantially as described.
