UNITED STATES PATENT OEEIcE.
RICHARD MONTGOMERY, OF NEW YORK, N. Y.
IMPROVEMENT IN MACHINES FOR MANUFACTURING WAVED AND CORRUGATED METAL PLATES.
Specification forming part of Letters Patent No. 24,882, dated July 26, 1859.
To a/ZZ whom it may concern: A
Be itknown that I, RICHARD MONTGOMERY, of the city, county, and State of New York, have invented an Improved Device for Making TVaved and Corrugated Plates; and I do hereby declare that the following is a full and exact description of its construction and operation, reference being had to the accompanyin g drawing, and to the letters of reference marked thereon, so as to enable others skilled in the art to use my invention.
The drawing represents a perspective view of the machine.
Two rolls I J are arranged (one above the other) between the u prights E F of a suitable frame E F S T. The lower roll J has fixed bearings in the uprights E F, while the upper roll I has its bearings in blocks C D, which can be moved up or down in vertical slots in the uprights E F. Screws A B work through female screws in the cross-pieces H G and bear with their lower ends against the upper surfaces of the blocks C D, so as to limit the vertical play of the blocks C D. It will be seen that by screwing down the screws A B the blocks O D, and with them the roll I, will be made to approach the lower roll J, so as to decrease the distance between the surfaces of the two rolls or the open space between them, through which the Inetal to be rolled is intended to pass. The journals K L of the two rolls extend through the block D and upright F, respectively, and the ends of the journals K L are provided with cog-wheels M N, gearing into each other, so as to cause the rolls to revolve against each other whenever Inotion is communicated to one of the rolls, which latter is done by means of a crank-pulley or other suitable device attached to the shaft of the lower roll J, extending beyond the upright E. The cogs of the wheels M and N are of sufficient length to keep the wheels in gear during all adjustments of the blocks C D required for practical purposes. The rolls are each provided with a series of ribsP Q R and depressions or recesses I Q R. These ribs are of a uniform height above the cylindrical body of the rolls, and each of the ribs extends in a continuous zigzag or waved line around its roll, the ribs being parallel to each other, as fully shown in the drawing. These ribs of the two rolls are so arranged in relation to each other that the ribs of one roll will fit into the recesses formed between each two of the ribs of the other roll, and vice versa. Both ends of each roll near the bearings are provided with smooth cylindrical shoulders O of a diameter smaller than that of the ribs.
When a metal plate is to be rolled, power is applied to the crank or pulley at the end of the shaft of the roll J after the upper roll I has been adjusted to a suitable height above the lower roll J by means of the screws A B, and the red-hot metal plate is passed toward the rolls so that its front edge is caught between the two rolls,when the revolutions of the rolls will commence to draw the plate through the space between the rolls. During this process the ribs of the rolls will form the surface of the plate into waved corrugations eXtending lengthwise of the plate. Then the whole length or nearly the whole length of the plate has passed through between the rolls, the motion of the shaft of roll J, and consequently the revolution of each of the rolls, may be reversed by reversing the motion of the crank or other suitable means, which will cause the plate to move back. TVhen the whole length or nearly the whole length of the plate has again passed through between the rolls, the motion of the rolls is again reversed, as above described, thus working the plate back and forth until nished. After each passage ot' the plate through between the rolls the screws A B may be turned down a little, so as to force the roll I toward the lower roll, thus causing the corrugations of the plate as it is worked back and forth to become gradually deeper, while the-metal becomes correspondingly thinner.
It will be seen that by always reversing the mot-ion of the rolls at a certain distance from the edges of the plate, instead of allowing the entire length of the plate to pass through between the rolls, smooth margins will be left along the front and rear edges of the plate.
The side margins of the plate passing through between the smooth cylindrical shoulders O will-also be kept smooth, and these side margins will bethicker than the other parts of the plates, because the shoulders O are of smaller diameter than the ribs of the rolls, and thus leave a wider space between these shoulders than what there is between the corrugated surfaces of the rolls.
As the ribs are not cylindric, but ot' a zigzag shape or waved shape, the plate after having been worked through these rolls will also rep ture of the waved corrugated, metallic plate with margins of greater thickness than the middle, as patented to me on the 21st of June,
1859, is faci1itated,whi1e a portion of each corrugation is formed at the same time, as described.
