MAGHINE no.3. sIMULTANE uSLY-"FLANGING D DOUBLE" SEAMING THE ENDS on METAL "CONTAINERS 1 Application filed N'ovemb'e'r 7, 1929, Serial No. 405,366, andiii Great Britain J'une 4, 1929.

This invention relates to machines for simultazneously flanging and double seaming the ends of. metal containers, and it .has for its object certain improvements whereby the desired operations may be'efi'ected inv a much more rapid and efficient manner than is possible with machines forthispurpose as generally c0nstructed=..

According to this invention the container is supportedby' means of chucks'which,in the known manner, are inserted in the flanged end closures-previously applied. to the container; The'fianging: is eiiected by meansof a roller mounted upon an arm having a radial movement towards and away from. the rear face of the chuck, and in a plane. at .a right angle-to the-plane of rotation of the said chuck The arm is spring'actuated in-onedirection and is positively operated against the action of. the. spring'at the desired intervals to-cause the roller thereonto act upon the end of the container, a roller is also provided cooperating with' the'chuck during the flanging operation. Otherrollers arranged in a known manner eifectt'he curling and flattening operations.

The invention; further provides improved means for presenting the containers to the chucks. V

A machine embodying the present inventlOIlz conveniently ,comprise a suitable frame supporting coaxially disposed suitably spaced. shafts. driven, in. any suitable manner, each of said-.shaftsat. inner end beingprovidedwithabody carrying spindles also-a1; ranged. axial alignment and disposedin planes parallel'to the axis ofthe shafts carry-.

Figs. 5 and 6 are perspective views showing certain details.

Figs. 7, 8, 9 and 10 are views showing the various stages of the process of placing the ends upon a container.

Referring to the accompanying drawings 1 indicates the base of the machine mounted upon which are brackets 2, 3 having formed integral therewith bearings 4, 5 in which is carried a horizontally disposed'shaft 6, which extends from end to end of the machine.

Freely mounted upon the shaft 6 and extending through a bearing 7 formed integral with abracket 8, is a sleeve 9. Disposed at points near each end of the shaft 6, and keyed thereto are pinions 10, 10 disposed within gear boxes 11, 11 revolubly mounted upon the saidshaft and provided at diametrically opposite points with bearings 12, in which are carried horizontally disposed shafts 13 which extend inwardly of the machine and at their inner ends carry chucks 14, the said shafts 13, being supported at points near their inner ends by means of bearings 15.

Ihe bearings 15, which are arranged to slide in a horizontal plane are carried within channels or recesses 16, formed in bodies 17 extending between and formed integral with the bearings 12, and substantially rectangular shaped plates or bodies 18, formed'integral with the inner ends of bosses 19, surrounding the shaft 6 and cast upon the gear boxes 11, 11.

Disposed within the gear boxes 11, 11 and splined upon the shafts 13 are pinions 20 with whichengage the aforementioned pinions 10, the arrangement being such that when motion is transmitted to the shaft 6 in a manner to be hereinafter described, the chucks 14 are caused to revolve.

Mounted upon the shaft 6 and secured at its ends to the bodies 18 is a tubular body or sleeve 21, which in effect serves to rigidly connect the gear box 11, with the gear box 11. The aforementioned sleeve 9 is at its inner end provided with a flange 9 by means of which the said sleeve is secured to the gear box 11 in order that when motion is transmitted to the sleeve from a main drive shaft 22, provided with fast and loose pulleys 23 and 24, respectively, and a pinion 25, which engages with a pinion 26 keyed to the said sleeve. 9, the gear boxes 11, 11, are revolved about the shaft 6. 27 indicates a countershaft mounted in bearings 28, 29 carried upon or formed integral with the brackets 3 and 8' respectively and having mounted thereon a pinion 30 with which engages a pinion-31 keyed to the sleeve 9 whereby motion is imparted to the said countershaft.

Keyed upon the countershaft 27 is a sprocket wheel 32 from which motion is imparted to the shaft 6, by means of a chain 33,

which passes around the said sprocket wheel 32, and a second sprocket wheel 34, upon the said shaft 6.

Disposed upon either side of the machine and carried upon the upper ends of pairs of standards 35, 35 and 36, 36, respectively, are horizontally disposed girders between which is supported a substantially arcuate member which extends over the centre of the machine and carries upon each of its sides adjustably mounted brackets37, each provided at their lower extremities with bearings 38, 39 in which are mounted spindles 40, which carry supporting rollers 41, curling rollers 42, 43 and flattening rollers 44, such as shown in Fig. 2.

45, 45 indicate vertically disposed brackets or frames mounted upon the base of the ma chine and mounted upon each of which is an annulus 46, provided upon its respective faces with cam surfaces 47 and 48 such as indicated more clearly in Fig. 5, and with which cam faces engage rollers 49, 50 mounted within slotted lugs 51 formed integral with the upper portions of each bearing 15, the arrangement being such that when the gear boxes 11, 11 are in motion, the bearings 15 are reeiprocated longitudinally of the machine.

In order to cause the shafts 13, to be reciprocated with the bearings 15 the said shafts are provided with collars 15 15 The shape of the cam surfaces 47 and48 is such that, when the chucks 14, which as will be readily seen from the foregoing description, revolve bodily around the shaft 6, are travelling through a certain portion of their path of rotation about the shaft 6 they are caused to move toward each other to grip the container in the manner shown in Fig. 7, and carry it successively into engagement with the aforementioned rollers 41, 42, 43, and 44, after which the said cam faces cause the chucks to separate and release the said container.

Mounted or formed upon the inner faces of each of the standards 35, 35, are lugs 52, 53

which form bearings for spindles 54, upon which are pivotally mounted the outer ends of levers 55, the inner ends of which are bifurcated and carry spindles 56, upon which are mounted flanging rollers 57.

Carried by means of brackets 58 and projecting from the inner face of each of the bearings 15 is a cam 59, and mounted upon each of'the spindles 56, in the path of movement of each of the said cams, is a roller 60, the purpose of the cams being to engage with the rollers 60, and cause the levers to be moved against the action of springs 55, and toward. each other as the container is brought under the edge of the supporting rollers 41, to increase the flange on the end blanks there of and at the same time form a flange upon each end ofthe wall of the said container in cover. flanges to extend beyond. said body flanges,'means= for curling the cover flanges. inwardly down and. overthe body flanges,

means for. flattening the flanges so curled,

the-manner shown in Fig. 8. v I

1 The containenafter passingunder the-ac; tion of flanging rollers 57, is successively moved into engagement with the pairs of curling rollers 42, 43 where it is operated upon in the manner shown in Fig.9, after which it is moved into engagement with the flattening rollers 44:, in the mannershown in Fig.10'.

61 indicates acradle into which the'containersare placed, and in which they are fed to the chucks; the said cradle being-carried upon the outer endseof bodies 62, revolubly mounted upon the sleeve'2l as shownrmore' clearly in Fig. 5 in. which the said cradleis'to be seen in its lowermost p'ostion and resting.

upon rollers 63, 63, mounted upon a spindle 64 carried by a bearing 65 formed upon the inner end of an inclined lever 66 pivotally mountedat its outer end upon a shaft 67 car'- ried in bearings 681noun'ted upon the base 1.

The inner end of the lever 66 is normally supported upon the upper endof a piston rod 69 connected at its lower end toanv oil filled dashpot 7 O. Clamped aroundthe sleeve 21 are semi-circular bodies 71, 71?, provided with outwardly extending portions or members 7 2, 72", respectively, which projectfrom opposite sides of the saidsleeve, and. are so designed thatwhen the sleeveis' in rotation they successively engage with the inner end of the lever 66;

When one or other of the members '72 or z 7 2 engages with the'inner end of the lever 66, the said lever is raised, the cradle together with the container therein thus being the chucks, the respective member 72 or 72*, I

as the case may he, passes out of contact with the end of the lever 66, and permits the same together with the cradle to return to-its lowermost position, the cradle itself being pro vided with a slot 73 through which the said member passes after moving out of contact with the lever. I 7

Whilst the cradle is being raised, the piston-rod is caused, by means of a spring acting upon the dashpotpiston, to rise intoits uppermost position, in which position it is ready to subsequently permit the cradle to be eased gently into lowermost position. I,
