PatentedNov. so, 1915;.

hinged half molds on the carrier are provided each with a can body ejector or arm which engages the can body when the hinged half mold opensand thus ejects the flanged can body froml the mold and delivers it into the. discharge. chute asthe carrier rotates.

The side guides between which the flanging molds on the carrier pass are provided with converging and adJustable centering gu des, preterablyof a yielding character, or coning tool spindles mounted on thecarrier, one

set at each end of the molds- The carrier is preferably composed of a number/ofseparate heads secured together and rotating as a unit, and it is preferably supported and journaledon a central stationary or nonrotatable sh'aft fixed tothe frame.

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.

One embodimentof my invention, and the preferred one, is illustrated in the accompanying drawing forming a part of this specification.

In said drawing, Figure l is a side elevation of a can body flanging machine embodying my invention. Fig. 2 is anend view. Fig. 3 is a detail, central, vertical section. Fig. l is a detail vertical section on line of Fig. Figs; 5, 6 and. 7 are d,e tailsectionson lines. 5 5, 6+6 and1-77.of Fig; 4 respectively. Fig.8 is a detail perspective. view showing. one of. the Hanging molds of the carrier. Fig. 9 isa detail, section showing the side. guides for'centering the-can bodies and the centering springsor devices, with which the. side guides, are,.pro,-. ided, and Fig; .10 is added section oi onef-I th flan ingamolds; andgo the. fiangin te ers eoact gther with,

' ll epnj msth immsei furnished with an arm 24 connected by a the machine, 12 a continuously rotating carrier, preferably supported :and journaled upon a fixed or non rotating central shaft 13 supported in suitable brackets 14 on the frameof the machine. The carrier 12, for convenience of construction, is preferably composed of a number of separate pieces or heads 15, 16, 17 and 18. The continuously rotating carrier 12 is furnished with a plurality of'fianging molds19, preferably six in number each slightly less than the--can body in length and conforming thereto in diameter, and each havingwa segment or jaw 20 adapted to open and close toreceive and clamp the can body in the mold. The inner or fixed segment-of the mold is preferably made integral with the heads 15 and 16 of the carrier. The hinged or opening and closing segment 20 of the mold is connected to the fixed segment by a hinge or pivot pin 21 and is opened and closed preferably by means of a stationary cam 22 securedto the fixed shaft 13 and fitting in a chamber 23 provided for itfin the carrier heads 15, 16.

Eachof the hinged half molds or jaws 20'is link 25 having a roller 26 which travels in the stationary cam 22 as the carrier rotates. Each of the molds 19 has a registering shoulder or ledge 27 for the free edge 28 of the hinged jaw 20 to shut against. Each member ofthe flanging mold is also provided with an ejector or arm 29 fitting in the corresponding recess 30 of the other member of the mold when the hinged jaw of the mold is closed, and which engages the can body and operates to automatically eject the flanged can body from each member of the mold when the hinged member 20 opens, as will be readily understood from Fig. 8 of the drawing. The ejector arms or fingers 29 are preferablyin separate pieces from the segments of the mold and secured thereto by screws. Two are preferably attached to the fixed member 19. of each mold and two to the hinged member 20 thereof. The can bodies 31 which are to be provided with flanges 32 at each end are automatically delivered one by one to the flanging molds by a delivery chute 33 to which the can bodies are fed by an elevator 34 having fingers 35.

The feed chute 33 is preferably furnished witha curved spring holder 36 for retaining the last can body in the delivery end of the chute 33 until it is forced out of the chute into the open mold 19 on the carrier 12 by the fingers acting upon adjacent can bodies in the chute 33. 7

After the hinged halfmolds or jaws 20 have been closed upon the can by operation of the stationary cam 22 and the connecting links 25,the jaws 20 are held firmly closed during the seaming operation by means of a curved guide or shoe 37 whichisengaged by rollers 38 journaled on arms 39 of the jaws molds and adapted to reciprocate, and each also to be rotated on its own axis. Each of these reciprocating and axially rotating flanging tool spindles is furnished with a spur gear46 which meshes with a central gear 47, the teeth of which are made wide enough to admit of the necessary longitudinal movement of the spindle 45 without disengaging its spur gear 46 from the central gear 47. The flanging tool spindles 45 are automatically reciprocated as required, preferably by means of stationary cams 48 on the frame of the machine, which are engaged by yoke levers 49 carrying rollers 50 for engagement with the cams and pivoted to lugs 51 on the head 18 of the carrier 12, and which yoke levers'have pins engaging grooved collars 52 fixed to the spindles 45, a coiled spring 53 serving to retract the Spindles 45. i 9 Each of, the flanging tool spindles 45 has secured thereto a tool holder or crank arm 54 furnished with a screw stud 55 upon "which is journaled a flanging roller 56, the same being furnished with a curved face or shoulder 57 adapted to coiiperate with the end face or shoulder 58 of the flanging mold 19, 20 to turn or form the flange 32 on the can body 31 as the flanging roller rotates on its own axis and is carried around the interior of the flanging mold by'the' axially rotating flanging tool spindle 45.

The central gear 47, instead of being stationary orfixed to the central shaft 13 is rotated in the opposite direction from the carrier 12 and isfurnishedwith a sleeve 59 surrounding the central shaft 13 carrying a gear 60 which meshes with a gear 61 on the countershaft 62 which meshes with a gear 63 on the shaft 64. The carrier 12 is furnished with a spur gear preferably in a separate piece from the head 18 and bolted thereto, and which meshes with a gear 66 on the shaft 64. The shaft 64 and the gears 60, 61', 63, 65 and 66'and countershaft 62 are duplicated at each end of the ma-. chine and one of the shafts 64 is furnished with a driving pulley 67. 1

After the can bodies are flanged they are discharged from the flanging molds into a discharge chute 68 which delivers them to the elevator or conveyer 69 for'the flanged can bodies.

In order to accurately center the can bodagrenaes end of the can :body, .I provide the 'side guides on the frame of the machine-and.

between which the Hanging molds pass as the carrier rotates with slightly converging and adjustable centering guides .71, the same fitting in slots 72 inthe side guides 70 and securedthereto at one end by screws .73 and fitting at their free ends against adjusting screws 74. The centering guides 71 are preferably off a yielding character or composed 'ofi'flat springs so that the outer ends of the springsm-ay yieldand permitan abnormally long can body .to pass without binding or sticking. The side guides 70 are cut away, as will be readily understood from Fig. 3, toadmit the Hanging rollers into the ends of the can bodies.
