(Cl. 153—73) 2 1 The present invention has for its purpose to The present invention relates to an improved machine for impressing strengthening ribs or beads in the cylindrical surfaces of can bodies and the like. Such strengthening beads are con overcome all of the di?iculties encountered with machines of the prior art. . , . A primary object of the invention is to pro vide a machine capable of forming in the side walls of can bodies, reinforcing ribs, grooves or beads of greater depth and uniformity than has ventionally employed in can bodies toprevent denting or collapse thereof and to make possible the use of lighter sheet metal stock than would been possible heretofore. i otherwise be possible.‘ In order to decrease the A further object is to provide means for pre thickness of the sheet metal employed in the manufacture of can bodies, attempts have been 10 venting slippage between the inner and outer beading rolls of can beading ‘machines, or, in other words, between the can supporting man drels, the can bodies and the beading rolls. Another object. is to provide‘ means which will made to form the strengthening beads of maxi mum depth, thereby to compensate for the strength and stiffness ordinarily imparted to th bodies by heavier stock. - ‘ In accordance with conventional methods and 15 make it possible to apply greater beading pres sure to the can bodies,‘ yet which will- facilitate machines, prior to the present invention, passage of the side seams through the bight be~ strengthening beads have been formed in the tween the mandrels and the beading rolls. cylindrical side walls of can bodies by the use of A further object is to provide means for sup can body supporting mandrels having peripheral grooves formed therein, and cooperating can body 20 porting the free ends of the internal beading rolls or can supporting mandrels, to the end that beading rolls positioned exteriorly of the can‘ they may withstand greater beading pressure bodies and having complemental ribs thereon. applied thereto by the external beading rolls. In these machines, the bodies are rolled between Still another object is to provide an improved the mandrels andthe beading rolls, and the beads thereby impressed. An example of a ma 25 means for rotating the can body supporting man-. drels and, in combination therewith, to provide chine of the prior art is shown in the patent to improved means for imparting positive rotation to the beading rolls, irrespective of their radial positions relative to the mandrels. Kreuger 2,081,042. In such'machines, the can bodies are subjected to the action of instrumen talities of this type and the strengthening beads are ‘formed therein by cooperating ribs and 30 . Other and further objectsand advantages of the invention will be apparent to persons skilled in the art, from a consideration of the speci?c grooves on the surfaces of the beading rolls and can supporting mandrels, respectively. The roll ing force is transmitted from the can supporting mandrel, through the can body thereon, to the embodiment of the invention shown in the ac companying drawings, in which: exteriorly positioned beading roll, by means of 35 a plurality of rubber rings interspersed between the bead forming or die rings of hardened metal. .

A cylindrical turret extension 2|, connected to the head |‘|, projects lateraly, co axially with the shaft l3, toward the opposite The sleeves 55 have bearing assemblies 51, 58 at their opposite ends, in which spindles 59 are jour~ end of the machine, where it is secured to a large 20 nalled. Each spindle carries on its rear end a spur gear 22, journalled on the shaft l3 upon spur gear 60 and on its forward‘ (end a beading , bearings 23. The turret extension 2| comprises a cylindrical portion 24 of reduced diameter and another cylindrical portion 25-‘ of large diameter mandrel 6|, composed of alternate rubber and steel rings 62, 63, the latter having, beading grooves 64 formed in their peripheries. The man connected thereto‘ by a radial’ Web 25' provided 25 drel is provided at its rear end with a hub 65 with a plurality of pairs of guiding, bores 25, for terminating in a spur gear'56, and at its forward the reception of‘ can body carrying rods 21, 28,, end with a hub (ill, screwed’ onto the spindle 59 described in detail below. At the end adjacent and having a reduced‘ portion58 for the reception its connection to the gear‘ 22, the turret extension of a ‘roller 99, held in place by an end cap 10, is provided with an inwardly projecting flange 30 restrained against endwise movement by a screw 29‘, similarly provided With bores 39 for‘ support ‘H and against rotation byv a dowel pin 12. ing and guiding the rods 21, 28. It will be apparent that, by this construction, It will be noted‘ that the‘ turret IS, the turret the rings 62, 63 may be removed and others sub extension 2| and the‘ large spur gear 22 are all interconnected for rotation upon the stationary shaft |3 in unison. The shaft carries a cam barrel 35', secured against rotation by a key 36, stituted, to accommodate can bodies of various sizes and to produce strengthening beads of various spacings and depths. , The turret heads l6 ‘and H are provided’ with a plurality of radially disposed bores or slideways ‘i5, 76, which receive supporting means for the and having a pheripheral cam track or groove 31 formed therein, provided with an advanced sec tion at its upper portion and a retracted section 40 beading rolls Tl, positioned radially inwardly of at its lower portion. Cam following rollers‘ 38, the outer beading rolls or mandrels 6|.

In other words, the rods 21, 28‘ and the can body engaging members carried‘ thereby, in Figures 7, 8 and 10, each beading roll support comprises a rack sleeve 18 slidably mounted in one of the bores or slideways l5, ‘l6 and having on. At its upper end, the sleeve terminates in a’ heavy compression springs 83, 84, bearing up wardly against a bearing bracket v85 provided with 9, depending stem 86, slidably received in the bore of the sleeve ‘l8 and having a nut 81-, threaded on its projecting end, ‘below the sleeve 18. The springs 83, 84 normally‘ maintain the which reciprocate as the turret revolves, serve 55 ‘bearing bracket 85 in the upwardly projected‘ to move the cans to and from operative relation position, as determined by the engagement of’ to the beading instrumentalities. As indicated in Figure 4, an infeed star wheel or spider 45‘, fast on a shaft 46, is positioned ad jacent the bottom of an infeed chute 41, down which the container bodies roll by gravity from the preceding machine in the line. The star wheel 45 is- rotated. in timed relation to the ro tation of the turret, so that can bodies are fed the nut 87' with the end of the sleeve 18, leav ing a space 88 between the lower face of the bracket 85 and the upper surface of the plat form 88. A cap 89, secured to the bracket by screw 99, secures the bearing assembly 9| thereto. Each bearing assembly 9| (Figure 10) supports one end of a spindle or shaft 92 for the beading roll 11, made up of a plurality of alternate rubber into the spaces between the rods 21, 28, the. end 65 and metallic rings 93, 94, the latter beingpro guide plates 40, 4| and the cradle members 42, vided with outwardly projecting beading ribs 95, 43, when the rods are intheir retracted position, positionedin alignment with the heading grooves as shown at the bottom of Figure. 2. As thecans move around with the can. holders on the turret, and as they are advanced by the movement of the rods, they are supported by a curved, for wardly leading guide p1ate48 until they have been placed upon and are supported by the bead ing mandrels, hereinafter described.
