The object of this invention is to provide an apparatus for economically fastening the sheet-metal bottom on a sheet-metal vessel and at the same time forming the curled bead on the rim of the vessel, as more fully hereinafter set forth. In the drawing Fig. 1 is a vertical sectional view showing an apparatus capable. of carrying out-my metho p Fi 2 is a detail cross-sectional v 1ew showmg the parts in osition at the com- Referring to the drawing annexed by refcreme-characters, 5 desi ates a base having formed on it a central circular boss 6, at the base of which is formed an annular groove 7 formin one-half of the rim-bead die. The other ha f of the rim-bead die is formed in two dielates 8 removably resting upon the base an provided with a complementary die-groove 9.
Upstanding from the center of the boss 6 is a ri 'd post 10, and slidingly'fittin down overt is post is a sleeve 11 which epends from the top wall of a cylindrical form 12 whose lower ed e sliding lly embraces the outer wall of the 0s 6. his form 12 is taered upwardly and is held in its up position y means of a strong coil-spring 13. I Reci rocatingl su ported (by meails not shown; above t e orm, is a die-head 14 whose lower edge 15 is cylindrically shaped and is adapted, when the die-head 1s fprced down, to embrace and fit around the u per end of the form 12. Within this dieead is formed an annular semi-circular diegroove 16, and centrally within the diehead is mounted a circular plunger 17 havin an upstanding guide-pin 18 and a air 0- expansible e01 springs 19 normally orcing the plunger downwardly to the limit of its downward movem'ent,this limit brin 'ng the lower face of the plunger 17 on a p ane below thedie-groove 16.
The open-ended, tapered can or bucketbody 20 is sli ped down over the form 12 with its rim-e ge lying in the dieroove 7, this ed e being preferably sli ht y flared outwardly before the bucketbo y is put on the form. Previously formed in the bucketbody, by pressing the metal annularly inwardly, is an inwardly-extending open bead 21,- this bead being ositioned at a distance from the bottom point where it willrest upon the top edge ,lar flange 23 exten in out the area of the ing the bottom ge of the bucket, at 'a of the form 12 when the rim edge is resting previousl formed and shaped as described, is thus? seed on the form, the bottom disk 22 is dro ped into placeon the bead 21, this bottom 'sk being toward the bottom edge of the buckety, which flan lies against the interior of the bucket-bo and is desirably previously curled inwardly slightly.
After the parts of the bucket are thus placed on the form, the die-head is forcibly moved downwardly. The first result of the downward movement of the die-head is to cause a downward movement of the form 12 a ainst the action of ring 13 and thus curl t e rim-edge of the ucket body by means of thedie- grooves 7 and 9. Further movement of the die-head downwardl crushes or flattens the bead 21 and curls the ttom rimedge of the bucket-body and the flange 23' inwardly to thus not only solidly interlock these flanges but also to solidly clamp the bottom-plate against the bead 21. The spring-pressed p unger 17 serves not only to assist in curling the bottom flange of the bucket, but also to clamp the bottom plate solidly in position ainst the head throughttom plate durin all the operations, the normal position 0 e the plunger 17 being such that it desirably comes into contact w1th the bottomplate 22 at about the same moment that the die-groove 16 comes in contact with the bottom rim of the vessel. In this way, it will be observed that the entire operation P of beading the rim-edge of the vessel and" fastening in the bottom plate is accomplished with one stroke ofthe die-head.
