F. M. WQODS, OF YORK, ILLINOIS.
MACHINE FOR PRESSING SHEET-METAL PANS'.
Specification forming part of Letters Patent N 0. 50,4 [0, dated October 10, 1865.
To all whom it may concern Be it known that I, F. M. .WooDs, of York,-
in the county of Clark and State of Illinois, have invented a new and Improved Machine for Pressing Sheet-Metal Paris; and I do'hereby declare thatthe following is a full, clear,
and exact description thereof, which will enable others skilled in the art to make'and use -:th e same, reference being had-to the accompauying drawings, forming part of this specification, in which- Figure 1 represents a longitudinal vertical section of this invention. Fig.2 is a.horizo1i"- tal section of the same, the line we, Fig. 1-indicating the plane of section. Fig. 3 is an inverted planet the male die or punch detached. Fig. 4 is a detached plan of a piece-of sheet metal as the same appears when taken from.
this machine. Fig. 5 is a longitudinal section of one side of the female die detached. Fig. 6 is a detached sectional'view of the frame which I use for increasing the depth of the die.
'Similar letters ofreference indicate like parts.
from getting wrinkled. The sides of the die are made in sections, and they are held in-pos'ition by adjustable brackets in such-.a manner that by taking a greater or smaller number of sections for the die said die can be adjusted for pans of different sizes. The depth of the dieis adjusted by placing under the die one or more thin frames, whereby said die can 'be accommodated to pans of different depth.
A represents a bench or'table which is sup-' ported by four legs, 13, and the top or platform of which is made of sufficient strength for the occasion. I From this table rise two uprights, 0, the upper ends of which are united by a bar, D, and said uprights form the guides for a beam or gate, E, that carries the punch F, and to which arising-and-fallin g motion is imparted by a treadle, T, or other suitable means. This punch is secured tothe beam by means ofa stein or rod, G, the lower end of which fits in a corresponding socket in the punch, being fastened to the'sanie by a suitable key, so that it can be readily removed and replaced by another punch of larger or smaller size. The form of the punch is made to, correspond to the shape of the pansfto be produced, and from its corners project wings c,.which, .when the punch is depressed, fit into corresponding slots in the corners of the die H, and which serve to depress the corners of the sheet metal uniformly and prevent the sides of the pan. from becoming wrinkled, which they do if the sheet metal is somewhat weaker or softer in one corner than the other corner, and if from this or any'other cause the depressim tit-said sheetmetal is not uniform.
The dieHis arranged under the punch on top' of the table A, and it is held in position by four (more or less) adjustable brackets, 11. These brackets are secured to the table by screws 0, which pass through slots d, as clearly shown in Fig. 2, or by any other suitable means, so that they can be readily expanded oroontracted to correspond, to dies of diiferent size. The die It is constructed of a series of sections, which I are made wed ge-shaped, so that when the same are put together they hold each other in position, and either section is allowed to displace :itself spontaneously and independent of its neighbors. Small wedges or sections f are inserted between the large sections and the cor- 'ner pieces to hold the die in shape, and by removing the'small wedges the entire die can be taken to pieces.
A series of small wedges may be provided to be inserted-in the several sides of the die in order to adjust said die to larger or smaller pans. In order to adjust the die for pans of different depth, thin frames I are provided, which are placed under the "die as required.
The die is provided with a gooove g, near its inner edge and extending all round the same, and a lip, h, on the under edge of the punch is made to catch into this groove. By the action of this lip the requisite groove is turned on the edge of the sheet metal to receive the wire, and a very large number'of pans can be pressed by the aid of this machine in a comparatively shorttime. The pans on leav ing the machine require but little hand-labor to be finished, and. they are all uniform and free from wrinkles.
What I claim as new, and desire to secure by Letters Patent, is-' 1. The arrangementof wings a in the corners of the punch, in combination with correspondin g grooves in the corners of the die, substantially as and for the purpose described.
2. Making the (lie H in sections, substantially as and for-the purpose described.
