FRANK RUDOLPHl, OF CHICAGO, ILLINOIS, ASSIGNOR TO AMERICAN (JAN COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.
ROTARY SLlTTING-MACHINE FOR curfm'e SHEET-METAL (BAN-BODY BLANKS.
, To all whom it may concerrt:
Be it known that I, FRANK RUDOLPHI, a citizen of the United States, residing at Chicago,
in the county of Cook and State of Illinois,
have invented a new and'useful Improvement in RotarySlitting-Machines for Cutting Sheet- Metal (Jan-Body Blanks, of which the following is a specification. My inventlon relates to IIDPPOVBIIJGIltS' 1n 1 rotary slitting-machine for cutting metal sheet with the cutters, and Fig. 6 is sheets into can-body or other blanks of a simple, efiicient, and durable construction, by means of which the sheets may be squarely, rapidly, and accurately passed between ro- 'tary slitters and subdivided into can-body or other blanks Without any tendency to cause the sheets to buckle or pass askew betweenthe cutters, and by means of which the bur or turned edge produced by each pair of ro-' tary cutters or slitters may be turned both the same way on each blank or in opposite directions at the opposite edges of each blank, and in which the cutters may be readily adjusted.
My invention consists in the means I employ to practically accomplish thisobject or result as herein shown and describedthat is to say, in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described. 7 In the accompanying drawings, forming a part of this specification, Figure 1 is a rear elevation of a rotary slittingmachine em bodyiug my invention. Fig. 2 is 'a vertical section on line2 2 of Fig. l. Fig. 3 is adetail front elevation, partly in vertical section, showing the cutters arranged for turning the burs in opposite directions onthe opposite edges of each blank. Fig. 4 is a similar View showing the cutters arranged for turning the burs in the same direction on both edges of each blank. Fig. 5 is a detail vertical section show-.. ing the spring gage or stop for squaring the a detail rear elevation ofthe same.
. In the drawings, A represents the frameof the machine. B B are the shafts, to which the rotary cutting-disks CC and feed-rollers. D D are secured. Each of the upper feedrollers D is provided with a rubber or elastic ring d, fitting in an annular groove d,'to

give the feed-rollers an elastic grip .on the Patented Oct. 17, 1905.
sheet and cause the same to feed straight and true between the several pairs of rotary slitters.
Each of the lower feed-rollers D is provided with a reversible metallic tread-ring having a shouldered or raised bearing-face (Z at one end, adapted to oppose the elastic bearing-ring d on the upper roller I). Each of the opposing cutting-disks G O has a beveled peripheral face 0 andcutting edge 0, the two cutting edges of each pair of upperand lower disks O C opposing each other.- "Each of the disks 0 O are removabl y secured'to their respective rollers D D, so that by reversing each cutting-diskeither of its two opposite faces may be placed adjacent to its roller. Each of the rollers D D is provided withan annular shoulder orrecess (13* to receive its cutting-disk C or C.
The'cutting-disks O O are each removably secured to their respective rollers D D by screws cl. The metallic tread-rings 93 on the rollers D are removably and reversibly secured thereto by screws d, the heads d of which fitin shouldered recesses of, with which the tread (Z is provided at its opposite ends or edges to enable the tread-ring to be reversed, so as to bring the bearing-face d opposite the elastic'bearing-ring d on the upper roller D whether the cutting-disks C C be arranged as shown in Fig. 3 orin the reverse arrangement shown in Fig. 4. The rollers I) D are adjustably fixed to the shafts B B in different positions, as may be required, by
set-pins d and tight-fitting friction-plugs al having cam-faces (i bearing against the pins 01 and furnished with square heads (Z for.
turning the same.
F is the feed-table, the same being furnished with a reciprocating feed-slide F, which is connected by a link f with an arm f on a rock-shaftf' having'an arm f connectedby a link f with a crank-army, on the shaft B of the upper cutter C and roller 1).
G is an inclined guard-plate having a curved foot g, under which the sheet-is pushed over the feed-table F into the bite of the feed-rollers D D andIcutting-disks (J C, the inner edge of the feed-table and of this inclined ers and cutters. To square the front edge of the sheet with the cutters and cause the sheet to feed truly and properly into the cutters and feed-rolllers with --i-ts-- front edge parallel are furnished with metallic tread-rings, while to the axes of the cutter-shafts B B ,I provide the inclined guard-plateG with a plurality of pivotal spring-actuated sheet-squaring guards or devices g, the same being pivoted or hinged at g to ears or lugs g on the inclined guard-plate (fr, and yieldingly held in position by springs g". The forward movement of the sheet itself lifts or pushes the pivotal spring-actuated squaring-guard 9 out of the way as the sheet passes into the bite of the feed-rollers D D and cutters C C. The hinged sheet-squaring gages or devices 9 stop or retard the sheet as it is fed forward by the feed-gage F and causes the rear edge of the sheet to bear snugly and squarely against the feed-gage F at the time it enters the bite of the rollers D D and cutters O C.
By combining with the shafts and feed-rollers thereon reversible cutting-disks removably secured thereto and reversible treadrings re-' versibly secured to the rollers on one of the shafts I am not only enabled to turn the burs both in the same direction or in opposite directions, as may be desired, but Iam also enabled to subdivide the sheet into narrow strips or blanks by the rotary cutters, as in the arrangement shown in Fig. 4. The narrow space between adjacent slits or cutsonly equals the thickness .of one cutting-disk and its roller.
As in my invention the rollers on one shaft those on the other shaft are furnished with rubber or elastic tread-rings, the bearing-surface of the metal tread-rings may bealways maintained on a level or proper relation with the cutting edge of the cutting-disks, and consequently all danger of buckling the sheet or the other shaft having reversible metal treadrings, substantially as specified.
2. In a rotary sheet-metal-slitting machine the combination with upper and lower rotating shafts, of rollers and cut-disks on said shafts, the rollers on one of said shafts having elastic bearing-rings, and the rollers on rings furnished each with a raised bearingface, substantially as specified.
3. In a rotary sheet-metal-slitting machine the combination with a pair of shafts, ofrollers having elastic bearing-rings on one ofsaid shafts, rollers having removableaiid; reversible tread-rings on the other shaft, and reversible cutting-disks removablysecured to said rollers on said shafts, whereby the burs may be turned'the same way, or-turned. iu opposite directions, as desired, substantially as,
specified. 1 v FRANK RUDOLPHI. Witnesses: I I I H. M. MUNDAY, I I. ABRAMS.
