MACHINE FOR SHEABING on PUNCH'ING SHEET METAL.
SPECIFICATION forming part of Letters Patent N.377,7s0, dated February 14,1888.
Application filed J une 13, 1887.
.To all whom it may concern:
Be it known that I, LONGLEY Lnwrs SAGEN- DORPH, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Machines for Shearing and Punching Sheet Metal, of which the following is a specification.
The severalfeatures of my invention andthe advantages arising from their use, conjointly or otherwise, will be apparent from the following description.
In the accompanying drawings, forming part I of this specification, Figure 1 is a front elevation of my machine adapted for shearing, the legs being omitted. Fig. 2 is a top view of the machine, as shown in Fig. 1, the top of the frame-work and the toggle-arm mechanism being removed. Fig. 3 is a sectional elevation, the section being taken at the line 3 y, Fig.1,springs D being omitted. Fig. 4 is a front elevation of a machine embodying my improvements and adapted for punching. Fig. 5 is a plan view of thetable of the machine shown in-Fig. 4. Fig. 6 is a perspective view of one of the female dies receiving the punches illustrated in .Fig. 7. Fig. 7 is a perspective view of one of the punches used on the machine. Fig. 8 is a sectional e1evation, thesection being taken at the line or m, Fig. 4. Fig. 9 is an end elevation of the machine shown in Fig. 4, springs D being omitted. Fig. 10 is a perspective view of part of a roofing-plate punched in the machine shown in Fig. 4.
The frame A A supports the brackets 13,
and also the mechanism for operating the bar 0. The bar 0 is hung from the top of the frame-work by heavy springs D, which tend to raise it. It is guided in its movements by guides at the sides of the frame-work, in which the ends of the bar fit.
Serial No. 241,220. (No model.)
ble B and the cross-brace A,- and is securely attached to the latter. The vertical portion of the angleiron J carries the lower shearing ends vertical rods m, which have attached to their lower ends the clamping-bar m and provided at'their upper ends with the nuts m',
which prevent the rods m dropping through j the arms m. The springs m surround the rods m, and, pressing against the bars at above and the clamping-bar m below, tend to press the clamping-bar m downwardly.
To adapt the machine for punching, the
shearing-bars and angle-iron, and preferably,
also, the'gages and arms supporting them, are
removed and other attachments made. to'the machine, as illustrated in Figs. 4, 5 and 7.
Each of the punches H has its lower face beveled, as shown in Figs. 4 and 7, and one edge provided with the-bevel h, preferably making an angle of about onehundred and thirty-five degrees with the front face of the punch. To the rear face of the punch the guide-plate h is attached. The corresponding female die consists of a'shoe, I, which is at tached to the cross-brace A, and is provided with an opening to receive the die proper, I. The die I is provided with the opening i, which is shaped to receive the punchH and its attached guide-plate h. The plank B, forming the table in front of the machine, rests on the brackets B, and is preferably of such thickness as to make its top level with the top of the shoes I.
The mode of operation of the device is as follows: In shearing, the sheet or sheets to be out are put under the shear-blade J, with one edge against the gage Z or k, as necessity requires. The bar 0 is now lowered by means of the toggle-arm mechanism. The clamping bar 111. strikes the sheet and is pressed strongly too against it by the springs m as the bar continues to descend, and to cut the sheet ofmetal between the upper and lower shearing-bars, J and J. The clamping device is particularly valuable in connection with the shearing de' vice herein described, because in their joint use there is no drawing of the metal, and no allowance for drawing of the metal need be made upon the gage, whether one sheet or twenty be cut at a time.
In punching, the sheet of metal is placed under the punches H and against the guide-plates h. The bar 0 is now lowered, and the punches descending cut from the edge of the sheet the cleats p, as shown in Fig. 10. The beveled face h of the punch does not descend far enough to complete the cutting of the cleat from the sheet, so that the cleat is merely bent over at the edge of the female die, forming a crease, so that when the cleat is folded completely back on the line of this crease it is placed at right angles to the edge of the sheet. This constitutes one step in the preparation of the sheet for roofing purposes.
What I claim as new, and desire to secure by Letters Patent, is-- 1. In combination with the bar 0 and toggle-arm mechanism for operating the same, the shearing-bar J, angle-iron J, and shearing-bar J, and cross-brace A, substantially as and for the purposes specified.
2. In combination with the bar 0 and toggle-arm mechanism for operating the same, the shearing-bar J, crosspiece A, table 13, angleiron J, lower shearing-bar, J and clamping mechanism, substantially as and for the purposes specified.
3. In combination with the bar 0 and toggle-arm mechanism for operating the same, the shearing-bar J, cross-piece A, table B, angleiron J, lower shearingbar, J bars m, rods m, nuts m springs m, and clamping-bar m substantially as and for the purposes specified.
4. In combination with the bar 0 and toggle-arm mechanism for operating the same, the shearing-bar J, cross-piece A, table B, angleiron J, lower shearing-bar, J, bars on, rods m, nuts m springs m, and clamping-bar m, arms L, and gage Z, and arms K, and gage k, substantially as and for the purposes specified.
5. In combination with bar 0 and togglearm mechanism for operating the same, shearing-bars J J", and angle-iron J, and punches H, and dies I, the punches and dies being interchangeable with the angle-iron and shearing-bars, substantially as and for the purposes specified.
6. In combination with the bar 0 and toggle-arm mechanism for operating the same, the cross-brace A, shearing-bars J J, angle-iron J, and punches H, and dies I, the punches and dies being interchangeable with the angleiron and shearing-bar, substantially as and for the purposes specified.
