l MACHINE' Foa Secam@ can non Application med recenter 2c, 1922. serial No. 607,950.-
To all whom t may concern.'
Be it known that I, SAMUEL E. ALLERTON, a citizen of the United States, residing at Chicago, in the county of Cook and-State of v Illinois, have invented certain new and useful Improvements in Machines for Scoring Can Bodies,lof which the followingis ay specification.
This invention relates to improvements in machines for scoring can bodies.
In prior machines' used for scoring or forming grooves in can bodies, the several cutters have usually been mounted on .the same rotatable shaft. Where the cutters wear away unevenly, this resulted in varyi the depth of the grooves and making it dnicult to tear 0H the strip ,of metal when the finished can was later opened. Furthermore, diliiculty was encountered, due to the springing of the shaft. As the depth of the ooves is only a few thousandths of an inch,
1t has been very diiiicult heretofore to obtain grooves of uniform depth. l
My invention aims to overcome these difficulties by providing means for mountin the cutters on a ri d support, which wi not spring a precia ly, and arrangin the cutters one ehind the other on di erent sup orts, so that each forms a groove indevpen entl of the others.
One ofy the objects of the invention is to accomplish'lthis result by mounting the cutter so that it may rotate on a non-rotatable sup ort, thereby permitting the support to be astened very rigidly.
Another object is to provide a hard bushingA between the cutter and its support, to
re u
body
ce wear. Other objects and advantages will be apparent from the descri tion hereinafter given ofthe preferred 4em odiment of the invention. l
. In the drawingsl Figure 1 lis a top plan view of the ma chine which embodles the invention;
Fig. 2 is a' section on the line 2-2 ofv Fig. 1;
Fig. 3 isa plan view of the blank or can Fig. .li-is an elevation of one of collars; and
Fig'. 5 is an elevation of one of the cutters or scoring knives.
Power 1s transmitted to the ,pulley 1 the driving mounted on a; shaft 2, the latter carryin a' ear13, which drives other gears 4, 5 an 6 irough a series of idler gears 7,l 8 and 9.
rollers are driven b is confined .entirely --As shown in the sectionall view of Fi 2,
the gear 6- is mounted on ashaft .1() w ich rotates in a bushing or bearing 11 and has a collar 12 to prevent endwise movement.
' The shaft has a reduced extension 13 passing through a bearing 14 with a gear 15 on the end `thereoit,-which meshes with a gear 16 above it, thereby driving a shaft 17 parallel to and mounted above the shaft 13. The' bearing is forced upwardly by means of springs 18 and may be adjusted by means studs 18 and 19. The collar 20 is provided with a plurality of projecting 20',
21 in the cutter.v The bushing 22 is held onto the end of the shaft 23 by a plate 22.
.The blank'passin through the machine slides along the eway 24 which'extends i fromone end olthe machine'to the other and passes under the successive 'cutters 21,
25,26 and 27, each of which'is mounted and driven in a manner'similar to the first' one described. Said cutters do not rotate in the each one being set over a little further from the end of the the blank 28 Fig. 3) in parallel lines spaced apart a short distance. The blank before leaving the machine passes between two rollers 29, which draw the blank' from i under the cutters and also iiatten it. These a train of gears 30, 31 and 32. The ui eway 24 may be curved and the axes of t e cutters arranged radially,in grooving a body for a tapering can.
The support for the bushing 22, being nonrotatable, may be very ri 'dly mounted so it will not yield apprecie l as the cutter 21, for exam le, vrotates above the. lower roller 33 wit the blank between them. Furthermore, such wearas does take place bushing, whereas 1t is uniformly distributed over the cutter and the bushing may there- `fore be rotated to prolong its use. vFurthermore, its support 23 may. be very accurately adjusted so as tov rovide for a the exact thousandt s.4 of an inch esired.
By the arrangement I provide, ofcutters mounted in series one behind theother, the
to the lower. side of thel which engage in a plurality of .ra ial slots i same plane, however, but in parallel planes ideway 24 so as to scoreV roove of depth et each groove may be accurately adjusted and no one cutter is dependent for itsy accuracy upon the others, as has been the case heretofore when several cutters have been mounted on the same shaft. 'ln the ma' chimes used heretofore, a large precentage of the can bodies scored have been detective,
whereas with my improved machine the deective products have been almost eliminated. i f" Although the cuttersl in the machine shown in the drawings are positively driven,
they may be mounted asI idlers and turned by the blank dpassing between them and the positivel' I riven rollers beneath. v
What claim is l. lin a machine ofthe class described, a
' rotatable shaft, a stationary support in axial stationary support, a bushing thereon, a rotatable cutter mounted on said bushing, said bushing being adapted tor adjustment tor maintaining said cutter in position to cut grooves of unitorm depth and means tor rotating said cutter.,v
4;, ln a machine ot the class described, a rotatable shaft, a stationary support in axial alinement therewith, a cutter rotatably mounted on said support, and means tor driving said cutter :trom said shaft, said driving means being carried on the end ot said shatt adjacentxsaid cutter. l
5. ln a machine of the class described, a rotatable shaft, a stationary support in axial alinement therewith, a cutter' rotatably mounted on said support, and means tor ioneaa driving said vcutter trom said shaft, mid driving means being carried on the end ot said shaft adjacent said cutter and having a portion engageable therewith.
6. ln combination, two parallel rotatable shafts, means ltor driving one trom the other, a tired support mounted at the end ot one ot said shafts, a cutter rotatably mounted thereon and driven trom said adyacent shaft, and a roller mounted on the' other shaft in the plane ot said cutter. A
7. ln a machine ot the class-described, comprising a bed plate, a series ot stationary supporting membem mounted thereon, a bushing on the end ot each ot said members, a cutter rotatably mounted on each ot' said bushings, said cutters being mounted to rotate in separate and distinct planes parallel to each other, a rotatable shaft passing beneath each ot said supporting members and extending beyond the same, a rotatable shaft labove each ot said last named shafts parallel thereto and terminating adjacent said cutters, gears tor driving one ot said sbatte trom! the otherl in each pair, and means turning with said last mentioned shatts tor rotating said cutters.
8.- ln a machine of the class described, a rotatable shatt, a stationary support in arial alinement therewith, a cutter rotatably carried by said support, driving means 'tor said cutter carried by said shaft, and means tor compensating tor the wear ot said cutter.
9., ln a machine ot the class described, a rotatable shaft, a stationary support in axial alinement therewith, a bushing on said support, a cutter rotatably carried b said bushing, and driving means on said s att for rotating said cutter, said bushing being adjustable. on said support to compensate tor the wear oi said cutter.
lin testimony whereof, l have subscribed my name.,
