WILLIAM cLEEsATrEL, 0F BUFFALO, NEW YORK.
ME-TVAL-FORIVIING MACHINE.
To all whom it may concern.'
Be it knownA that I, WTILLIAM CLEESATTEL, a citizen ofthe United States, residing at Buffalo, in the county of Erie and State of N ew York, have invented a new and useful Improvement in Metal-FormingMachines,
of which the following is a specification.
My invention relates to metal forming ma chines.
More particularly it relates to improve# ments in machines for bending and forming sheet metal plates into such irregular and fianged forms as mud-guards for automobiles and the like.
The objects of my invention are to provide a machinel for the accurate, perfect and rapid formation of plates variously and irregularly curved, to form perfect anges thereon and to form such plates with rapidity and uniformity hitherto unattained.
Further objects Vand the operation of my invention will be understood from the following specification and from the drawings herewith in which,
Figure 1 is a rear elevation of my machine. Fig. 2 is an end elevation, the driving pulley and idler being omitted for clearness. Fig. 3 is a detail section on the line 3 3, Fig. 1. Fig. 4 is a detail. section on the line 4 4, Fig. 1, showing the parts in position to form a plate with a comparatively sharp curvature or curved upon comparatively short radii. Fig. 5 is a similar view, the parts being adjusted to form the plate with the desired flange substantially in plane. Fig. G is a detail section upon the line 6 6, looking toward the right in Fig. 4, showing the forming or die rolls. Fig. 7 is a detail of one of my adjustable bearings, hereafter described. Fig. 8 is a detail perspective of a part of a mud-guard formed on my machine.
The frame 10 of the machine carries upon it two heavy bearing-castings 11. Mounted in the castings 11 are two bearings 12 which,
are adjustable in vertical plane by means of screws 13. These bearings support the shaft 14 upon which is rigidly mounted the female roll-die l5. Mounted in vertical plane in bearings hereafter described is the shaft 16 which has rigidly mounted upon it the male roll-die 17. These two shafts and their rolldies are positively driven at equal speed by the following gearing: A driving shaft 18 upon which are mounted the ordinary beltpulleys carries the gear 19, which meshes with the gear 20, which is in rotation upon Specification of Letters Patent.
a vcommon shaft with a gear 21, whichj is in mesh with a gear 22, which is rigid upon the shaft 14, which shaft also carries the gear 23 which is in mesh with a gear 24 of equalfdi- Patented J an. 4, 1916.- i Application med Maren 9, 1915. seriai No. 13,150. I i i ameter and'rigid upon the shaft 16. It Qw'il'lfr be seen that by this train of gearing powerful action is given to the shafts 14 and`1'6` and to the die-rolls 15 and The roll-die 15 has end flanges 25 for turn.-
ing up the Aedges of the metal plate to be formed which overlap the vends of the vroll-v die 17 leaving intervening spaces correspond-` ing to the thickness of the meta-l treated.' To assist further in the perfect Hanging of the plate l'pivot to the bearing castings 11 the p ange bars 27, which` are spaced apart equally with the end flanges 25fand ride upon them.v llhese flange bars 27 hold the flanges formed by the dies while the plate is being curved as presently described.
To facilitate remov'al'and replacement ofv the die-roll 17 or the insertion of another similar roll of different size toadapt the machine to metal of different thickness the upper halves of the bearings of the shaft 16 are pivoted to the bearing castings, as shown at 28 in Fig. 3, and the free ends of these bearings are held by swivel-bolts 29 which are pivoted to the bearing castings and which take through slots in the ends of the` pivoted bearing members and are held by hand-nuts 38 which screw down upon the said bearing members. i
In order to form the plate and side flanges.-
as above described and also to give any lon-v gitudinal curvature desired mount sliding bearings 30 in the bearing castings to the rear of the bearings ofthe die-rolls and preferably on lines slightly vout of vertical, as shown. These bearings carry the shaft 31 of the idler roll 32, and these bearings are adjustable simultaneously and substantially equally by means of the screws 33, sprockets 34 and sprocket chain 35. This roll 32 is thus adjustable in and out of the path of travel of the sheet metal through the dierolls, and may be lowered entirely out of saidV path as shown in Fig. 5, or may be brought into the path of travel as shown in Fig. 4. Then in the path as shown in said last-mentioned figure, it will deflect Yand curve the metal upon a constant radius if the adjustment of the bearings of said idler roll remains constant; but if the said bearingsy are adjusted Yduringil'the process by means of said screws, sprockets and sprocketchains, the curvature will be varied according to the change of adjustment made. By so changing the position of the vidler roll during the process of formation of the plate any desired degree or change of curvature may be secured. It is now to be observed that, as the plate 26 is thus being curved by the idler roller, the flange bars 27 hold the side flanges in proper position and prevent buckling or other irregularity While the plate is being curved. rind it is also to be noted that, as the shafts la and 16 are much longer than the roll-dies l5 and 17 and as the bearings of the shaft 14 are adjustable, by the use of dies of if'arious lengths, contour, or diameter, plates may be formed of different Widths and forms.
In Fig. 7 have shown one of the bearings 30 provided with a. pointer 36 and a scale 37 stamped into the bearing casting. By means of this pointer and scale the projection of the idler roll into the path of the plate may be deiinitely determined and the curvature of the plate also accurately predetermined.
Having thus described my invention, I claim:
l. .ln a machine of the type described, in combination With positively and equally driven male and female roll-dies, end-flanges upon said female die overlapping the ends of the male die with suiiicient intervening space only for the side fianges of the metal plate and flange bars pivotally secured to a fixed portion of the machine having their free ends riding upon the flange ends of said female roll-die and spaced equidistantly with said end fianges, to insure the perfect formation of the side anges of the plate.
2. In a machine of the type described, the combination of positively and equally-driven male and female roll-dies, said female die having end flanges overlapping the ends of the male die with sufficient intervening space only for the side flanges of the metal plate and flange bars pivotally secured to a fixed portion of the machine, said parts coacting` to produce the transverse shaping, with means for curving the plate longitudinally immediately following the transverse shaping comprising an idler-roll. mounted in ad justable bearings to project said idlerfroll to a greater or less degree into the path of travel of the plate through said dies and means for adjusting said idler-roll.
