ASSEMBLING MECHANISM FOR CAN BODIES AND HEADS.

Be it known that I, JAMES A. GRAY, a citizen of the United States, residing at San Francisco, California, have invented certain new and useful Improvements in Assembling Mechanism for Can Bodies and Heads, of which the following is a specification.

My invention relates to means for feeding can heads to be assembled with the can bodies, my object being to provide a feeding mechanism which will depend upon the presence of the can body in" controlling the feed of-the head to be assembled therewith, that is to say, as long as the can bodies are fed to the chuck in proper order and time, the heads to'be assembled with these bodies will also be fed to the chuck; but when, for any reason, the feed of thecan bodies be comes irregular or ceases, the feed of the heads will also be arrested. I

The invention consists in the features and combination and arrangement of parts here inafter described and more particularly pointed out in the claims.

In the accompanying drawings Figure 1 is a plan view of a chuck for assembling the heads and bodies of cans with my feeding mechanism in connection therewith; Fig. 2 is a detail View of a stack of can heads with the devices directly adjacent thereto in sec tion, which devices form parts of the feeding mechanism; Fig. 3 is a longitudinal sectional View through the feeding mechanism and the chuck with parts in elevation; Fig. 4 is a plan view of the crimping dies for uniting the head and can body, this view showing one part of the die moved inwardly and the other in its outermost position; Fig. 5 is a detail view of one-of the -plungers for operating the dies.

In these drawings, 1 indicates a chuck having a recess or opening at 2 of substanthe can head, said in its lower portion,

chuck having mounted,

ental form, as shown die members 3 of segm these, and each being adapted to move radially in relation to the 4 indicates a vertically'movable plunger or head having its lower face shaped to conform at 5 to the shape of the can head, and 6 indicates a vertically movable plunger or carrier for the can body, which is shown in position thereon at 7.

are introduced into the chuck from a Way or opening9' at one side thereof,fand for this purpose I-employ a over the edge of the can thrust plate or feeder 10' moving on guide- I ways 11 extending out from the chuck, the said thrust plate being reciprocated in the guides through. any suitable connection, a portion of which is pivotally connected to the thrust plate at 13. The can heads are arranged in a stack or pile at 14, the lowermost one resting upon movable supporting members 15,. one on each side of the guldeway, and in the form of arms pivoted at the points 16 to the guide .frame or bracket, and connected together at 17 by a pin and slot. These supports are operated to and from the position shown s of a link 17 connected with a controller lever or arm 18 by a pivot at 19, the said controller lever being pivotally mounted at 20 and having a curved end in the path of the can body 7 on its way to the" ehuck. On each side of the guideway I employ an arm or retainer 21 pivotally mounted on the guideway frame at 22, and each having a roller 23 on its forwardly extending arm to be engaged by the side edge of the thrust plate or feeder 10, which side edge, at the front and rear corners. The retainers 21 have arc-shaped jaws which are serrated and are curved to conform to the periphery of the heads.

In combination with a chuck, a'reciprothe chuck to be positioned by the plunger 1 in proper relation to the can body for the crimping action of the dies. The forward movement of the thrust plate will also result in spreading the forward arms of the retainers 21, and causing their serrated areshaped arms to grip the next to the lowest can head to hold this, together with the pile or stack of can heads, against falling down while the thrust plate is performing its function, and this supporting effect of the stack or pile of can'heads will be maintained so long as the thrust block or plate is in its forward movement for delivering i the can head to the chuck the stack resting on the plate itself after it releases the roller 23.
