MACHINE FOR CUTTING 0R TRIMMING PACKS OF METAL SHEETS.
SPECIFICATION forming part of Letters Patent No. 560,065, dated May 12, 1896.
Application filed December 5,1894. Renewed December 9, 1895. Serial No. 571,598. (No model.)
To all whom it may concern.-
Be it known that I, JOHN G. HODGSON, a citizen of the United States, residing in Maywood, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Machines for Cutting or Trimming Packs of Metal Sheets, of which the following is a specification.
My invention relates to machines for cutting or trimming sheets of metal in packs. Thin sheets of iron or steel are customarily rolled in packs of, for example, eight or more. The edges of the pack as it comes from the rolling-mill are more or less irregular or uneven, and before the sheets can be tinned it is necessary to trim or straighten the edges of the sheets and to square the sheets. Owing to the thickness of the pack and its uneven edges it is a matter of difficulty to start and feed the pack properly between the rotary cutters or feed-rollers of the trimmingmachine. To practically overcome this difficulty, I combine with the feed-table of the trimming-machine swinging or yielding gages or guides for the rough side edge of the pack to fit against, the gages swinging or yielding to permit the projections or inequalities at the edge of the pack to pass, and in order to cause the pack to enter straight and squarely between the feed-rollers and rotary cutters of the machine I combine with the feed-table a sliding clamp adapted to travel upon a suitable guide or bar and to be clamped firmly to the pack at its back edge, so that the pack is forced to travel in a straight line with this clamp and thus properly and squarely enter the machine.
My invention primarily consists in these features or combinations.
It also consists in the novel devices and novel combinations of parts and devices here in shown and described, and more particularly pointed out in the claims.
In the accompanying drawings, which form a part of this specification, I have illustrated at Figure l, in plan view, one good form of machine for embodying my invention in practice, and that which I believe to be the best form therefor now known to me. Fig. 2 is a vertical longitudinal section on the line 2 2 of Fig. 1. Fig. 3 is an enlarged detail perspective view of one of the swinging or yield ing gages. Figs. 4 and 5 are vertical sections on lines 4 4 and 5 5, respectively, of Fig. 1.
Fig. 6 is a side elevation looking toward the Each part is indicated by the samereference-letter throughout all the figures.
In the drawings, A represents the frame of the machine.
B B are the upper and lower rotary cutters between which the pack X is passed to trim off its rough or irregular side edges 00 00.
C C are the feed-rollers by which the pack is fed or forced between the rotary cutters, and O O are the discharge-rollers.
D D are the swinging or yielding gages against which the rough or irregularside edge of the pack abuts as it passes into and through the machine.
E is the feed-table, F the sliding clamp, and F the guide or bar upon which the sliding clamp travels.
G G and G G are two pairs of upper and lower bridges or guides extending between the upper and lower rotary cutters for supporting and guiding the pack as it passes through the machine and is being operated upon by the cutters.
The shafts 13"", upon which the rotary cutters B B are secured, are mounted in suitable bearings B B which fit in the housings B B and are adapted to be adjusted up and down, as required for thicker or thinner packs or to accommodate the wear or grinding away of the rotary cutters, by means of adjusting screws B B The housing B at one end of the shafts B is provided with removable gibs B B secured in place by threaded bolts B to permit the bearings B B to be bodily removed 9 5 and the rotary cutters B B to be slipped off the shafts B when required for grinding or replacing, the opening in the housing 13,
closed by the gibs B being made large enough to permit the rotary cutters to pass through the same. The rotary cutters each consist of a steel disk removably secured to a head I) by bolts 1). Each of the heads I) are adjustable on the shafts B to permit the cutters to be set closer together or farther apart as may be necessary for trimming packs of different widths. The cutter-heads b are secured in place on the shaft B by set-screws b in connection with the spline b on the shafts B The swinging or yielding gages D D are pivotally mounted upon adjustable blocks D, fixed to the table E by set-screws D passing through slots cl in said blocks D, and the swinging or yielding gages D are preferably held in their normal position by springs cl, coiled around the pivot d of the movable gage D. The pack X is placed upon the table and shoved against the gages D D. The gages are held by the springs d against the blocks D firmly in position, and as the force or blow of the pack comes directly in line with the pivot of the swinging gage the gage will not yield at this time, but, on the contrary, serve to properly adjust or position the pack on the feed-table E. When, however, the rough-edged pack moves forward into the bite of the feed-rollers O and rotary cutters B B, the gages D D may readily swing or yield to accommodate any projections or inequalities on the edge of the pack. The feed-table E is furnished with a slot or openin g E to permit the sliding pack-clamp ll to move forward with the pack until the pack is firmly under the control of the feed-rollers C O and rotary cutters B B. The sliding clamp F may be of any suitable form or construction adapted to travel upon its guide or bar F. For convenience, however, its movable or pivoted jaw f is preferably provided with a hand-lever f for closing or locking the clamp and with a dog or lever f for automatically opening the clamp and releasing the pack therefrom after the pack has advanced sufficiently far into the machine to become fully under the control of the feed-rollers and rotary cutters so that the pack no longer requires the guiding action of the sliding clamp. The lever or dog f operates to thus automatically open the clamp by striking against the table E at or near the end of the slot E or against other fixed part or projection on the machine. The sliding clamp F thus serves as a traveling guide for the pack. The upper and lower bridges G G are secured to cross-bars g g, the portion of these bridges which extends between the rotary cutters being made in separate or removable sections, so that by removing these removable sections of the bridges both pairs of the rotary cutters maybe slipped off the shafts B at the end of said shafts opposite the driving-gears. H is the drivingshaft connected by gears h h with one of the shafts B from which the other shaft B is driven by gears 7L h Motion is communicated to the shafts of the feed-rollers O O by the train of gears h 71, h. The feed-rollers O C are furnished with a separate drivingpulley H and are connected together by gears h". The frame A is provided with slots E to permit the discharge-rollers O C to be set nearer to or farther from the rotary cutters as may be necessary to accommodate packs of difierent lengths.
I claim 1. In a machine for trimming or cutting sheet-metal packs, the combination with the rotary cutters and feed-rollers,of a feed-t ble, a pair of swinging or yielding gages on the table for the side edge of the pack to fit against and adapted to swing or yield toward the rotary cutters as the pack advances and a sliding or traveling guide or clamp to hold and guide the pack, substantially as specified. 2.
