| 241 | Metal container forming apparatus | US586023 | 1975-06-11 | US4007620A | 1977-02-15 | Joseph J. Urban |
| An improved apparatus for forming drawn and ironed containers from metal blanks. A duplex drive mechanism rotated by a single motive device translates rotary into recipricatory motion by means of pivoted levers, transmitting it to the reciprocating carriages of a pair of juxtaposed machines through linkages having disengagable latches so that one machine may be disconnected while the other remains in operation. A pair of disc-like cams are provided, one operating a stripper punch disposed within an ironing ram used to advance metal blanks through successively smaller forming dies. The other cam is used to control the operation of a redraw die disposed about the ironing ram and which acts in concert with the ram to redraw blanks fed into the machine. Each carriage is articulated, force being applied to a rear portion of the carriage through linkages coupled to a source of motive power. A toggle linkage for operating the stripper punch is also carried by the rearward portion of the carriage. The ironing ram itself is carried by the forward portion of the carriage, the articulation joint in the carriage serving to isolate the forward portion from lateral forces applied to the rear portion. | ||||||

| A tray moves beneath a punch to catch a part which is knocked downwardly out of the punch as the latter is retracted. Thereafter, the tray is shifted rearwardly from the punch along a generally arcuate path and with an accelerated motion so as to throw the part away from the punch with a positive slinging action.

| 243 | Knockout arrangement for presses | US44568274 | 1974-02-25 | US3878706A | 1975-04-22 | BERRY GORDON C; KEITHLEY HARRY E |
| A vertically reciprocable press slide is provided with knockout pins reciprocably supported by the slide for movement between extended and retracted positions relative thereto. The pins are reciprocated between extended and retracted positions by a lever mechanism which is actuated by a cam mounted on the press frame and a cam follower mounted on the lever mechanism. The cam follower is engaged by the cam during upward movement of the slide to both extend and retract the knockout pins. During downward movement of the slide the cam follower idles relative to the lever mechanism whereby the knockout pins remain in the retracted positions.

| 244 | Cap making machines | US3738147D | 1971-06-28 | US3738147A | 1973-06-12 | FORD G; WAITE P |
| A twin-tool press for a machine for making caps for bottles and other containers from metal foil includes two tool sets for blanking and forming caps from the same strip of foil arranged so that the line between their centers is inclined at an angle of about 60* to the longitudinal axis of the strip. The blanks simultaneously cut by the two tools therefore form two rows down the length of the strip. The two tools sets comprise two punch assemblies carried on a horizontally reciprocating plunger and co-operating, stationary, die assemblies. The metal foil strip is intermittently fed between the assemblies and the plunger is reciprocated so that the assemblies co-operate to effect blanking and forming operations during the periods when the foil is stationary. The caps are retained inside the punches as the plunger retracts after a blanking and forming operation and the punch assemblies include ejector rings for ejecting the caps from within the punches. The ejector ring of the upper punch is arranged to operate subsequently to that of the lower punch so that the two caps, which are formed simultaneously, are ejected successively to reduce the risk of the caps jamming or wedging as they drop down into the mouth of a cap delivery chute.

| AN EJECTOR ASSMELBY FOR EJECTING BLANKS FROM THE DIE AREA OF A PRESS HAVING MULTIPLE DIES. THE DIES ARE ARRANGED DIAGONALLY ACROSS THE PRES BED, AND THE EJECTOR ASSEMBLY IS POSITIONED ON ONE SIDE OF THE PRESS SO THAT SOME OF THE DIES ARE REMOTE FROM THE ASSEMBLY. THE ASSEMBLY COMPRISES A KICKER ARM PIVOTABLY SUSPENDED FROM THE PRESS ABOVE THE DIE AREA, AN ELONGATED KICKER SLIDE, A STATIONARY SLIDE HOLDER MOUNTED ON THE PRESS ON WHICH THE KICKER SLIDE IS GUIDED INTO AN OUT OF THE AREA OF THE REMOTE DIES, AND LINKAGE MEANS CONNECTING THE KICKER ARM WITH THE KICKER SLIDE TO TRANSLATE ARCUATE MOTION OF THE ARM INTO LINEAR MOTION OF THE SLIDE. A CAM MEANS ON THE PRESS RAM ACTUATES THE KICKER ARM IN TIMED RELATIONSHIP THEREWITH WHEREBY THE SLIDE EJECTS BLANKS FROM THE DIE AREA.

| THE DISCLOSURE IS OF AN IMPROVED MECHANISM FOR EJECTING A WORKPIECE FROM A MATRIX AFTER FORMING THEREIN AND INCLUDES A ROCKER SHAFT CARRYING AN ADJUSTABLE CAM PIVOTED THEREON ON AN AXIS PARALLEL TO THE AXIS OF THE ROCKER SHAFT, A LEVER HAVING AN EJECTING ARM AND A FOLLOWER ARM, THE LATTER ENGAGING THE CAM ON THE ROCKER SHAFT.

| A COLD FORMING PRESS WHEREIN THE ARTICLES ARE EXPELLED FROM THE MATRICES BY RECIPROCABLE KNOCKOUT PINS RECEIVING MOTION FROM A RECIPROCABLE CONNECTING ROD OF VARIABLE LENGTH WHICH IS DRIVEN BY A CAM. THE CONNECTION BETWEEN THE KNOCKOUT PINS AND THE CONNECTING ROD COMPRISES A FIRST BELL-CRANK LEVER ONE ARM OF WHICH IS COUPLED TO THE ROD AND THE OTHER ARM OF WHICH IS CONNECTED TO A FIRST LINK IN SUCH A WAY THAT THE AXES OF THE OTHER ARM AND THE FIRST LINK MAKE AN ANGLE OF AT LEAST 150 DEGREES IN THE STARTING POSITION OF THE CONNECTING ROD, A SECOND BELLCRANK LEVER ONE ARM OF WHICH IS COUPLED TO THE FIRST LINK, AND A SECOND LINK WHICH COUPLES THE OTHER ARM OF THE SECOND LEVER WITH A COMMON PUSHER FOR THE KNOCKOUT PINS AND WHOSE AXIS IS AT LEAST NEARLY PARALLEL TO THE AXIS OF KNOCKOUT PINS IN STARTING POSITION OF THE CONNECTING ROD. EACH KNOCKOUT PIN IS ADJUSTABLE AXIALLY WITH REFERENCE TO THE PUSHER.
