ISAAC VAN HAGEN, OF CHICAGO, ILLINOIS.
MACHINE FOR FQRMING CORNER-PIECESl FOR SlfOVE-BOARDS.
SPECIFICATION forming part of Letters Patent No. 355,235, dated December 28, 1886. Application filed March 17, isses. serial No. 195,599. (No madri.)
To all whom. it may concern:
Beit known that l, IsAAo VAN HAGEN, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvementsl in Machinery for Forming Corner-Pieces for Stove-Boards, of which the fol lowing is a specification, reference being had to the accompanying 4drawings, and to theletters of reference marked thereon.
The object of this invention is to bend, or bend and corrugate, the corner-pieces used with that class of stove-boards which are composed of a sheet or sheets of metal attached to a wooden base, and in which, necessarily, the corners ofthe wooden base would be exposed without the presence of acorner-piece separate from the sheet or sheets forming the main cover of the board.
In the accompanying drawings, Figure 1 is a vertical section of my improved machine in one of its positions. Fig. 2 is a similar view showing the machine in another position. Fig. 3 is a top view of the machine in the position shown in Fig. 1. Fig. 4 is a top View of the machine in the position shown in Fig. 2. Figs. 5, 6, and 8 are details. Fig. 7 is a perspective view of a corner-piece made by the machine constituting my invention.
Similar letters of reference indicate similar parts in the respective figures.
A is the frame or support of the machine, which is provided with standards a b. In these standards are supported shafts c d, which are geared together by toothed wheels e f. The shaft c is supported in Xed bearings,while the bearing for the shaft d in the standard a is provided with a movable upper box, g, and with an adj usting-screw, a', whereby the pressure on the shaft d may be regulated at pleasure. The bearing for the other end of the shaft d is pivoted to a support, b', 'which' is attached to the top plate, b, by means of the screw b.
' The end of the shaft d which projects beyond the support b is provided with a ring, d', to which is attached a spiral spring, d,which is connected at its other end to a hook, d, fast ened to the frame A. The shafts c d are provided with corrugating rollers or wheels c d', which extend beyond the front standard, a.
The frame A is provided with supports c c, (see Fig. 3,) to which is hinged by pins e f a strap or yoke, B, having a cross-bar, D. To the cross-bar D is riveted a bar, E, formed in the shape of an arch, in which is a hole through which passes the pin g', which is loosely attached to the disk G, and enters the projection g on the bar D. The arched bar E also forms a support for the disk G. To the upper part of the strap or yoke BJis hinged at g a spring strap or latch, C.- (Shown elevated in dotted lines in Fig. 4, and closed or latched in full lines in the same gure.)
F is a second disk, which fits over and concentrically with the disk G. The disk F is provided at its center with a pin, 71.', which passes loosely through the bar H, and is held in position by means of a washer, h, and pin h. The bar H is attached to the strap or latch C by means ofthe thumb-screws h4, which are provided with adjusting-nuts h5, by means of which the distance between the bar H and the strap C can be regulated. The bar H is provided with small wheels ti-one near each end-to relieve the friction between the bar H and the disk F when the latter is revolved.
The disk Gis provided with pins j, as shown in Fig. 6. These pins are for the purpose of holding the blanks 7s in position by means of the holes k. The disk F is grooved at k for the purpose of receiving the pins j and to allow the faces of the disks F and G to be brought close together.
In operation, supposing the machine to be in the position shown in Fig. l, the latch C, together with the bar H and the disk F, is lifted up, asshown in dotted lines, Fig. 4. The movable box g is raised up from the shaft d, and the spring d will then operate to raise the corrugated roller d from thecorrugated roller c. Four segmental pieces, 7c, of tin or other metal, are placed upon the disk G, the pieces being held in position by means of the pins j and holes 7c. They are then clamped between the disks F and Gby means of the latch C, the hook Z of which springs upon the under side of the strap or yoke B. The edges of the pieces k will extend beyond the edges of the disks F and G, and pass between the corrugated rollers c d a distance equal to the part to be bent over and corrugated. rIhe upper shaft, d, having been forced down by the screw a', so as to press the corrugated roller d onto the metal,
[OO f theyoke B is gradually allowed to fall to the positionV shown in Fig. 2. I The crank .I is vturned as the yoke falls, and the edges of the segmental pieces 7c will be bent to a right angle and at the same time corrugated. The number of revolutions having been given to the corrugating-rollers necessary to effect the oorrugating and bending of the corner-pieces, the upper bearing of the shaft D is loosened, the hook Z of the latch C is released by means of the handle I, and the latch C and the disk F are again elevated, as shown in dotted lines, Fig. 4,When the segmental pieces k, ,now formed into corner-pieces, are removed.
While I prefer to operate upon four plates or corner-pieces at one time, it'is obvious that a greater or lesser number maybe coincidently treated.
By the use of my invention great `rapidity of operation and accuracy of finish are effected. Having described my invention, I claim- 1. In a machine for bending and corrugating, the combination of a frame, adjustable corrugatingrollers', a hinged yoke having a. cross-bar, D, and spring-latch C, clamping- 25 disks F G, bar H, and adj usting-screws h, subf stantially as and for the purpose specified.
2. In a machine for bending and corrugating, the combination of a frame, ladjustable corrugating-rollers, hinged yoke having a 3o cross-bar, D, and spring-latch C, releasing-1ever I, clamping-disks F and G, bar H, having the wheels i, and adjustingscrews h, substantially as and for the purpose set'forth.
3. The clamping-disks F and G, one disk 35 having pins j, and the other disk being provided With a groove, k, substantially as and for the purpose specified.
In testimony whereof I have hereunto set my hand and seal.
