WILLIAM ERASTUS WILLIAMS, OF CHICAGO, ILLINOIS.
TOOL FOR MAKING WHEEL-DISKS.
. Specification of Letters Patent.
Patented Jan. 23, 19117.
Application filed June 12, 1915. Serial No. 33,699.
To all whom it may concern:
Be it known that I, lVILLIAM ERASTUS WILLIAMS, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented a new and useful Improvement in Tools for Making lVheel-Disks, as set forth in the annexed specification.
My invention relates to the tools required to form a sheet of metal into a disk by tapering corrugations across the sheet.
The invention is set forth in the claims.
Reference will be had to the accompanying drawings in which- Figure 1 is a perspective View of a partly formed disk. Fig. 2 is a perspective view of a completely formed disk. Fig. 3 is a sectional elevation through my tools, or dies as they may be called, in position ready to press or form a corrugation. Fig. 4 is a view similar to Fig. 3 showing the same parts in different position. Fig. 5 shows the working devices of Fig. 4, looking from the right in that figure, parts being broken away on the line 5-5. Fig. 6 is a plan of the bottom dies. Fig. 7 is a plan of the punch.
In the drawings 1 indicates a sheet in which there have been formed a few corrugations 2.
3 indicates a complete disk, wherein the dotted line 4 Fig. 2 indicates the joint of the two ends, which joint is welded brazed or otherwise suitably connected.
In place of starting with a fiat sheet as indicated by Fig. 1, I may form the sheet up into a cylinder and then corrugate the cylinder to disk form. in which case the dies will be slightly. modified to suit the work.
5 indicates my bottom die which is provided with a tapering cavity 6 and side sections 7 which have substantially the contour of the required finished disk.
8 indicates a pressure pad or stripper block of ordinary construction used in die work.
9 indicates a crosshead of any ordinary form of any suitable press or forming 10 indicates a punch block shaped like the cavity to be formed in the sheet between the corrugations. The block 10 is hinged by a pin 11 to a link 12 hinged by a pin 13 to the cross head 9.
Fixed to the link 12 there is a spring 14 power actuated which holds the block 10 in the position shown in Fig. 3 when not under pressure.
The nose 15 of the block 10 is curved the radius of curvature being substantiallv equal to the length of vthe corrugations in the sheet and this slides in the stripper block or pressure pad 8 and down the front narrow wall 16 of the die block 5 as the block descends in doing the work. As the block descends, under pressure of the press cross head, it rocks on the pin 11 and rotates on its heel 17 as a center and thus pushes down a tapering corrugation as desired drawing the Hat sheet until the part 1 of the sheet operated upon passes from its position in Fig. 3 to the position shown in Figs. 4 and 5 wherein 18 indicates the bottom of the corrugation.
But one corrugation is formed by the punch at a time. The sheet is fed forward at intervals the right distance for each operation. As the punch forms one corrugation the top faces of sections 7 of the bottom die form or rather keep the top surface of the plate of sheet 1 to the form of the adjacent corrugations so that actually two corrugations or a summit and a valley are formed each time the punch acts.
The dotted lines in Fig. 1 show on the flat sheet the wedge shaped sections 19 which form the vertical sides of the corrugations. The spaces 20 become the top faces and 18 the bottom faces of the corrugations.
A flange 21 is usually formed on the edge of the sheet or disk by making the sheet Wider than the length of the corrugations across the sheet, and then holding this portion flat by means of the pressure pad or stripper block during the punching. Dies of the ordinary kind are not adapted to make this sort of a corrugation because they act on the sheet at only one point of contact at a time which has the effect of tearing the sheet or buckling it up.
l/vhat I claimis:
1. In apparatus of the class described, the combination with a recessed die of a coacting die pivoted intermediate its ends to a plunger, whereby it may rest throughout its length upon the material to be formed yet rocks to accommodate itself to unequal resistance on opposite sides of its pivot.
2. The combination with a die having an elongated recess of a depth gradually increasing with the distance from one end, of a coacting die having a salient face and pivoted between its ends to rock in the axial plane of said recess.
3. The combination with a die having an elongated recess of a depth gradually increasing in passing from one end, of a centrally pivoted die having a salient face for coacting with the recessed die, and means for applying forming power to the centrally pivoted die at the pivotal point.
4. The combination with a die having an elongated recess of a-depth gradually increasing in passing from one end, of a coacting salient faced die, a power plunger, a link pivoted at one end to the plunger and at the other to the central portion of the second die, and a guide limiting the bodily swinging or the latter die as it is advanced by the plunger.
5. The combinatior with a die recessed to form in one side of a sheet metal strip transverse corrugations gradually decreasing in depth in passing toward the opposite side, of a centrally pivoted coacting die having corresponding salient portions and arranged r'or swingingbodily about one end while the pivotal point is advancing, and means for accurately guiding the salient die into the recess of the other die.
6. The combination with a die having a recess which gradually increases in depth in passing from one end and a curved guiding face at the deeper end, of a coacting salient die arranged for rocking on a central axis and swinging bodily about an axis near the end opposite said curved face, and a guide member holding the advancing end of the salient die in position to engage said curved face.
7. A device of the class described composed of a female die provided with taper ing side sections adjacent to a tapering cavity adapted to fit the outline of a segment of a corrugated disk, a punch adapted to coact with the cavity in the female die, said punch secured near its middle to a crosshead by hinged means and a spring acting to hold the punch in normal position with respect to its pivot.
8. A female die, a punch connected to a crosshead by linked connection and adapted to coact with the die in forming a tapering corrugation and to rock in its movement in the die.
9. A femaledie, a punch connected to a crosshead by linked connections and adapted to coact with the die in forming a tapering corrugation and to rock'in its movement in the die and a spring to hold the punch in normal position. 1
