W. H. BEACH, CF CHICAGO, ILLINOIS, ASSIGNCR TO J. S. BEACH, OF BALLSTON SPA, NEW YORK.
IMPROVEDIWACHINE FOR SWAGlNG SHEET METAL.
Specific ation forming part of Letters Patent No. 3 M347, dated February 5, 1861.
To aZZ whom, it may concern.-
Be it known that I, V. H. BEACH, of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Machine for Swaging and Pressing Sheet-Metal Plates for Rechng Purposes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification', in which- Figure l is a side view of my invention;
' Fig. 2, a transverse vertical section of the same, taken in the line x x, Fig. l.
Similar letters of reference indicate corresponding parts in the two gures.
This invention relates to a machine for swaging and pressing sheet-metal plates to form an improved roofing of peculiar construction. rIhe plates have semi-cylindrical ridges swaged at each side of them, and the portions of the plates between the ridges are pressed perfectly fiat and smooth and are held under pressure while the ridges are swaged, perforated with nail-holes, and the holes countersunk.
'Ihe object of the invention is to obtain a machine which will perform the desired work expeditiously and perfectly, so that the roofing previously alluded to may be economically applied, and a tight and durable roof obtained.
To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.
A A represent two uprights which are attached to suitable bases, B, and ab c are traverse-bars, which connect said uprights and are permanently secured to them.
C is a pressure bar or plunger which is htted between the uprights A A, and has dies D D attached to it,one at each side. The dies D are metal bars extending the whole length of bar C, and they have their ends fitted in vertical guides E, which are attached to the inner surfaces ofthe uprights. The under surfaces or face sides of the bars C are grooved longitudinally,l said grooves being of semicircular formintheir transverse section,as shown clearly at a' in Fig. 2.
F is a screw which passes through nuts d in The lower end of this screw is fitted in a step, e, on the upper surface of bar C.
In the bars or dies D D there are fitted vertical punches G. These punches have shoul- -ders f on them of convex form, as shown clearly at Fig. l. Each punch has a spiral spring, g, on it, and these springs have a tendency to keep the punches elevated.
H H are bars which are placed one at each side of the traverse-bar b, but are not attached to it. The bars H are male dies, their upper edges or faces having a semi-cylindrical ridge, h, corresponding inversely in form to the grooves a in the bars D, as shown clearly in Fig. 2. The ends of the bars H H are fitted in the guides E, and are allowed to slide freely therein, the bar resting on the upper ends of screws I, which work in nuts i in the lower traverse-bar, c.
The operation is as follows: The metal plates J to be operated upon are placed on the traverse-bar b,which serves as a bed-piece, and the bar or plunger C is pressed down upon it by turning the screw F. By this arrangement the bodies of the plates are pressed out perfectly fiat, so as to form plane surfaces. The edges or sides of the plates project out beyond the sides of the plunger C and bed or traversebar b, and while the center or body of the plate is under pressure the bars or dies H H are screwed up by turning the screws I I, and the convex ridges h of the bars or dies H force the sides of the plate into the female dies D, and the sides of the plate will consequently be swaged so as to form semi-cylindrical ridges. (See Fig. 2.) After the bars or male dies H are forced upward and the sides of the plate swaged, the punches G are forced down and the ridges of the plate perforated and countersunk, the shoulders f of the punches depressing or forcing down the ridges around the perforations. The faces of the dies H are perforated, as shown at b, Fig. l, to receive the punches. In case curved plates are required for curved roofs, the bed-piece, plunger, and dies are curved, so as to effect the desired result.
By this invention metal plates may be swaged at their sides, and their center parts or bodies compressed perfectly hat, the work done very quickly and in a perfect manner.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
2. In combination with the bar or plunger C, bed-piece b, and the dies D D H H, the punches and countersinks G, arranged essentially as and for the purpose set; forth.
WM. H. BEACH.
