CAN-BODY-FLANGING MACHINE.

Specification of Letters Patent.

Patented Feb. 8, 1910.

Application filed December 19, 1906. Serial No. 348,509.

To all whom it may concern:

Be it known that I, EDWIN V. SWAN- onnx, a citizen of the United States, residing in Maywood, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Can-Body-Flanging Machines, of which the following is a specification.

My invention relates to improvements in machines for Hanging bodies of sheet metal cans or other vessels preparatory to seaming the heads or covers thereon.

The object of my invention is to provide a can body Hanging machine of a simple, strong, eHicient and durable construction, .by means of which the bodies of sheet metal cans or other vessels may be rapidly and cheaply Hanged, in which the Hanging may be done gradually by a kind of drawing action without injury to the stock, and in which the cooperating Hanging disks or tools may separate or yield in respect to each other to accommodate the extra thickness of stock at the side seam of the can body, and by means of which the can bodies may be provided with uniform, true and perfect flanges so that hermetically tight and perfect double seams may be fomed by and between the seaming flanges of the can body and of the can body or cover.

My invention consists in the means I employ to practically accomplish this object or result. That is to say, it consists in a pair of'rotatable cooperating Hanging disks or tools, one having an internal or concave operating face or edge and the other an external or convex Hanging face or edge, and one movable or oscillatory in respect to the other, as required to turn the Hange.

It also consists in connection with such Hanging disks or tools in having one of them slightly separable from and yieldingly ield against the other to adapt the same to accommodate the extra thickness of stock at the side seam of the can body, and in combining therewith a yielding or cushioned supporting ring or chuck fitting inside the can body to support the same in true circular form during the Hanging operation and movable with the movable Hanging disk or tool and mounted on the rotary Hanging head which carries the two opposing Hanging disks or tools.

My invention also consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described and more particularly specified in the claims.

In the accompanying drawing forming a part of this specification, Figure 1 is a side elevation of a can body Hanging machine embodying my invention. Fig. 2 is an end view. Fig. 3 is a horizontal section on line 33 of Fig. 1. Fig. t is a detail central vertical section through one of the Hanging heads. Fig. 5 is a detail section on line 5-5 of Fig. 4 and Fig. 6 is a detail face view of the yielding or cushioned can body supporting ring or chuck which is mounted on the rotary Hanging head and which fits inside the can body to support the same in true circularshape during the Hanging operation. Figs. 7 and 8 are detail diagrammatic face views of the cooperating concave and convex Hanging disks or tools; Fig. 9 is a detail sectional view of the Hanging tools showing them in diHerent positions from that illustrated in Fig. l; and Figs. 10, 11 and 12 are detail views illustrating the operation and its gradual or drawing like action 111 producing the flange.

In the drawing A represents the frame of the machine.

B is a rotary Hanging head reniovably secured by screw threads b to its shaft B which is journaled in suitable bearings B on the frame of the machine.

C is the convex faced rotary Hanging disk or tool which is fixed to the rotary Hanging head or immovable in respect thereto, the same fitting in a suitable annular recess 6 in the rotary Hanging head B, and having a convex circular shoulder or Hanging face or edge C fitting inside and engaging the end of the can body X and operating in conjunction with the movable concave Hanging disk or tool D to turn the flange m on the can body X. This relatively fixed or stationary rotary Hanging disk or tool 0 is secured in place on the rotary Hanging head B by a face or wearing plate B which is preferably of brass or like metal and the inner edge of which overlaps the outer edge of the Hanging disk or tool C.

D is the cooperating movable or oscillatory rotary concave Hanging disk or tool, having an inside concave operating face or edge D the same rotating with and being mounted movably upon the rotary Hanging head B, preferably by means of a movable ring D having a circular opening (Z surrounding the hub b of the rotary flanging head B, and to which the flanging disk or tool D is secured by interengaging flanges (Z (Z and connecting belts or screws (Z rubber or other elastic cushions or springs (Z being inserted bet-ween the ring D and the heads (Z of the bolts (Z to enable the tool D to separate slightly or yield laterally in respect to the cooperating tool C sufiicient-ly to accommodate the extra thickness of the stock at the side seam of the can body. The rotary concave fianging disk or tool D is caused to rotate with the flanging head B by a radial guide pin (Z F is the yielding or cushioned supporting disk or chuck which flts inside the mouth of the can body X to support the same in true circular shape during the flanging operation and which moves with the movable concave flanging disk or tool D in respect to the rotary flanging head B and flanging disk or tool C while rotating with the rotary flanging head B and flanging'disks or tools C D. This supporting chuck or disk F is preferably held yieldingly in position as required by anaxially arranged spring F the opposite ends of which are connected to the head B and disk F by connecting buttons f f The axial spring F cooperates with annular wedging or tapering grooves or faces f (on the disk F) and b (on the rotary flang ing head B) to hold the can body supporting disk or chuckF yieldingly in position against the thrust of the movable flanging disk or tool D. The flanging tools C D have also parallel faces C D respectively at right angles to the convex face C of the tool C and concave face D of the tool D between which parallel faces the flange is received as it is turned or formed on the can body.

The movable concave flanging disk or tool D and the parts which move therewith are given the necessary oscillating movement in respect to the rotary flanging head B, preferably by means of a movable ring or strap Gr having a slot 9 and provided with a flange g engaging a flange (Z on the ring D and which ring or strap Gr 1S connected to a vertically reciprocating slide G actuated by a crank G on the countershaft G through the connecting rod or pitman G To give a cushioned or yielding action to the movable flanging disk or tool D, a spring G is preferably interposed between the two parts G and G of the connection between the ring or strap G and the slide G The slide G reciprocates in a suitable guide G on the frame of the machine, and it is provided with a horizontally extending slot or guideway g through which motion is communicated to the chuck or clamp disk H by which the can body X is clamped upon the rotary flanging head B and the yielding or movable can body supporting disk or chuck F carried thereby.

To give the can body clamping or chucking disk H the necessary in and out move ment to clamp the can body and also the necessary up and down movement with the movable flanging disk or tool D and yielding can body supporting chuck or disk F, the disk H is mounted upon an inwardly swinging and vertically movable lever H having a bent arm 7t furnished with a roller 7L fitting in and engaging the horirontal guide 9 of the slide G and which is movably connected to a stationary bracket H on the frame by a pin 7L2 extending through a vertical slot it in the bracket H The first portion of the downward movement of the slide G thus causes the arm H to swing inward toward the rotary flanging head B about the pivot 12, as a center and thus clamps the can body, and the further downward movement of the slide G is then caused to impart a parallel downward movement to the clamp or chuck H and its operating arm H by reason of the slot 7L Locking and releasing levers if 7r pivoted at it if to the stationary bracket H and pivotally connected together at their meeting ends, the lever it having a lip 71 overhanging the pivot pin 7L and the lever 705 having a lip it projecting under and en gaging the pivot of the roller 7L serve to lock the lever H in its closed position while permitting it to move down with the flanging disk D and can body chuck or support F, and serve, on the upward or opening movement of the slide G to permit the arm H and clamp disk H to swing outward to release the can.

The driving shaft B is furnished with fast and loose driving pulleys B B" and motion is communicated therefrom to the shaft G through the connecting chains and sprocket wheels K K I K K K. The machine is preferably made double or with two rotating flanging heads, one on each end of the shaft B and the other cooperating parts being, of course, duplicated.
