Application led october 21,1920. Serial No. 418,435..

il '0 all whom t may concern Be it known that 1, Parini KiiUsE, a citizen of the United States, residing-in the borough of Brooklyn, county of Kings, city and State of New York, have -invented certain new @and useful improvements in F langing Machines for Can Bodies, of which the following is a specification.

rlThis invention relates to can machinery or devices,'and aims to provide improvements therein.v

ln the practical art of.' can making, considerable dificulty has been encountered in developing amachine or device capable of satisfactorily flanging can bodieswhich are polygonal in sliape, especially at a speed for quantity production.

.The present invention provides a machine capable of producing satisfactory flanges, upon can' bodies of polygonal shape,and capable of performing the Hanging operation .at a rapid rate. v. thermore provides `a machine or vdevice in -whichthe construction is simple,"ecie`nt and durable. f An embodiment of the invention is illustrated in 4'the accompanying drawings, wherein Fig. 1 is a longitudinal, sectional view of the middle and one end or side of said embodiment. c

Fig. 2- is a view similar to Fig. 1, showing the parts in a different operativejposition.

Fig. 3 is a sectional view, at right angles to the section in Figs. 1 and 2.

associated parts. l

Referring to said drawing, X indicates a can body. y

The numeral 10 designates the means for turning over the edge or edges of a can body,

for the purpose of forming'a flange, such as indicated by the letter Fig. 2.

Suitable means 11`are providedjfor conlining the can body, preferably both eXteriorly and interiorly, during-,the flange forming operation,

lThese means preferably comprise the outer or Yfemale form 12, comprising tile separable bodies 13 and 1&1, andthe male form 15. 1.

The part 14 ofthe 'form conveniently forms a part of a :spider or drum 16, uponv an axial support 1.17. rlhe part 13 of the form is conveniently mounted on an arm 1i, pivoted, as indicated at 18, uponla slide 2f) The invention fur l rig. i is a dean View of the Slide 20, and

' ners, 32, and preferably wipe or slide past having movement toward and from the oper end of the can body. A spring 22, serves to press the arm 17, carrying the part 13, away from its closed position, and a cam 24, adapted to contactwith a roller 25, on ,the arm-17, serves for moving the part 14 to its closed position-L The form 15'is conveniently connected t.'- anfd carried by 'the slide 20, s and, hence, moves with the slide into and out of the can body X. Bolts 21 serve to-connect the forni 15 to the slide 20. v

The edge-turning or flange-forming means 10, are also conveniently carried by the slide 2O.y The ange-turning means 10 preferably comprises a plurality of segments 30,

preferably havinga movement along radial 'the planes f the sides of the can bodies, turning such vedges over and forming thereon a ange rThe liollow or female forni 12 is formed with aocorner 32, against or around which the edge of the 'can body is turned to form theflange, and there is a space 33,

Moreover,

ofthe can body closely adjacent 'to the corthe turned edges, and further preferably Means are provided for limiting or dctermining the amount of projection of the -edge portion of the body X over or beyond the sliulder or corner 32, on the form 12 thereby determining the width of the flange a2, and also bringing about a uniformity in the width of said flanges These means are conveniently 4in the form of a shoulder or step 34 on the segments 30. When the segments are collapsed, the shoulder 34 projects beyond the edges ofthe can body, and, when the slide or slides 20 move the group or groups of segments toward the can bodies inrtlie forms 12, the segments enter the can j' beyond the corner 32, which allows the edge "portion of the` can body to turn.

Athe segments 30, preferably engage the edge body until theshoulder 34 strikes the edge of the can body, and, if'this contact is made prior to the timethe slide 2O completes its movement, the canv body will thereafter move with the slide and segments 30 thereon, thus being centered or located by the action vof said slide, segments, and shoulder 34 thereon. Means, .such as .springs 37, vided for normally collapsing the segments 30, and means, s uch as a wedge-block; 39, is conveniently provided for spreading or eX- panding the segments. Slots 41 inthe segments 30, admitlof movement of the said segments on the bolts 21. The wedge-block 39 isA preferably carried upon a rod 47 slidably mounted in the slide 20. A spring' 50'serves for normally retracting the rod 47, and a cam 52,'acting upon a roller 53on the. said rod 47, serves to press said rod, to' cause the wedge-block 39 A' erably controlled by a cam 55 engaging a roller 56 on the said slide 20.

A vplurality of'v confining 'means 11, and flange-forming meanslO, constituting a unit, are provided,` and these' units are preferably arranged symmetrically around a shaft or axial support 117 ,n as shown in Fig. 3. The cam 55' is `arranged co;aXially,'or upon the shaft 117. The cam"24 is also preferably arranged co-axia'lly with the shaft orsupport 117. Y, .l

The cams 24, 52, and 55, on the one hand, and the confining means, or edge-turning or flange-forming means, on the other hand, are made relatively movable, whereby a conided. Tothis end, the unit or units" of conining and :edge-turningmeans are-preferably made rotatable, such rotation being conveniently effected through"4 the shaft 117. Rods 60, passing through the side frame of the machine, and fastened to the cam 55,

prevent said cam f rom turning. .The cam,24 is 'conveniently connected to tie-rods 62,

connecting the lside frames ,of the machine.

Where two. ends of a can body are to be flanged, as is usually the-case, thelanging construction is duplicated on opposite sides of the machine. v l

Operation: Can bodies from a. chute l70,

4pgeferably `drop into the portions 14 of the f K.

rm 12, during the rotation of the forms During this part of the movement, the springs 22. act upon the arms 17 to-separate or spread the part13 of the form from the part 14, and the cam 55 acts on the slide 2O,v in such manner as to draw the part 13 ofthe form,- and the male form 15, out' of the path of the can body as it drops into the part 14 of theform 12. .Thereupon, the cam 55 acts 'to push the slide'20 toward the can body, and the form 15 enters the can body, and, thereupon, or si' may be pro-- with .the cam 24, and pushes the arm 17,

carrymg the part 13 of the form 12, toward the part 14,'to close the form.

When the slide 2O moves toward the can body, the group 4of segments 30 are collapsed, and partially enter the can body. The vshoulder 34 thereof, if the cans are not propproperly located position.

When the part 13 is closed upon the p art 14, so as to confine the vcan body, cam 52 acts upon. roller 53 ofthe rod 47, carrying the wedge-block 39, and causes said wedgeblock to spread or expand the segments 30 of the die or edge-turning'means 10. The extent vto which the segments 30 project into the can body being limited by the shoulder' 34, the width of the'flange formed in the can body by the expansion of thesegments is constant. The movement of "these segments against the projecting edges lof the can body causes 'these' projecting' edges to be turned around the-'corners 32 of the form, thereby forming the flange Preferably, the segments act to slide against the sides of the turned over'e'dge, and presses and flattens the-said edges or flanges against the form.

Thereupon, the roller 25 passes off of the cam 24, allowing the spring 22 to push away the arm 17, thereby moving away the partl 13 of theform, and opening the form.4 The cam 55 thenac'ts upon the slide 20, through the roller 56, to 'withdraw the form 15. At

this instant, the canv body may be discharged. tinuously working `machine may be pro-- rl`he discharge is conveniently effected by arranging the machine so that the form opens,
