Abstract
Abstract An ejecting mechanism for a die press that utilizes the vertical motion of the ram to create a linear sweep of an ejecting plate across the face of the die bed. The ejecting mechanism provides a simple mechanical arrangement of parts which transforms the vertical motion of the ram into a linear motion of a carriage carrying the plate. The carriage is adjustably designed to carry a bouncer plate which both lifts and propels small articles falling from the raised die or a puller plate which pulls articles onto its face and out of the die area.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
193 words
An ejecting mechanism for use with a reciprocating die press or the like including a reciprocating ram movable toward and away from a stationary bed, said ejecting mechanism comprising: an L-shaped operating lever, means fOr mounting said lever for pivotable movement about an axis passing through the intersection of the lever arms, a circular bearing carried by one of said arms, a guide slot carried by said press, said guide slot receiving said circular bearing for transforming reciprocating motion of said press to rotary oscillation of said lever, a carriage mounted for reciprocation relative to the stationary bed of said die press and having a slot intermediate of its ends for receiving the other arm of said lever, ejecting plate means attached to the carriage and coordinated with movement of the ram to sweep the die area of any formed articles, slot means carried by said one lever arm, stud means extending outwardly from said circular bearing and received within said slot means to guide said bearing along said lever arm, and lockable adjusting means carried by said lever for adjusting the position of said circular bearing along the length of said arm.
Claim 2
Dependent Claim
193 words
An ejecting mechanism for use with a reciprocating die press or the like including a reciprocating ram movable toward and away from a stationary bed, said ejecting mechanism comprising: an L-shaped operating lever, means fOr mounting said lever for pivotable movement about an axis passing through the intersection of the lever arms, a circular bearing carried by one of said arms, a guide slot carried by said press, said guide slot receiving said circular bearing for transforming reciprocating motion of said press to rotary oscillation of said lever, a carriage mounted for reciprocation relative to the stationary bed of said die press and having a slot intermediate of its ends for receiving the other arm of said lever, ejecting plate means attached to the carriage and coordinated with movement of the ram to sweep the die area of any formed articles, slot means carried by said one lever arm, stud means extending outwardly from said circular bearing and received within said slot means to guide said bearing along said lever arm, and lockable adjusting means carried by said lever for adjusting the position of said circular bearing along the length of said arm.
Claim 3
Dependent Claim
51 words
The ejecting mechanism as claimed in claim 1, wherein said lockable adjusting means comprises a threaded adjustment screw slidingly carried by said one arm and fixedly coupled to said circular bearing, and a lock nut threadably carried by said screw for locking said adjusting screw relative to said one lever arm.
Claim 4
Dependent Claim
60 words
An ejecting mechanism as recited in claim 1, wherein the ejecting plate means comprises a bouncer plate attached to said carriage, said bouncer plate being formed of spring metal and terminating in a U-shaped bent portion defining a resilient, inclined surface to propel formed articles forward and upward as the bouncer plate sweeps the die area clear of the same.
Claim 5
Dependent Claim
76 words
An ejecting mechanism as recited in claim 2 wherein the plate means includes the puller plate having a slightly sloping face lying above the die bed and terminating in an upturned lip, and means for coordinating movement of the carriage and the ram to urge a formed article to slide up the slope of the puller plate face upon contact therewith and to slide down and off the puller plate as it stops and reverses direction.
Claim 6
Dependent Claim
46 words
An ejecting mechanism as recited in claim 1 further including means for adjustably connecting the plate head means for adjustably connecting the plate head means to the carriage to vary the sweep of the plate head means to meet the various requirements of the die press.
Claim 7
Dependent Claim
80 words
An ejecting mechanism as recited in claim 1 further comprising a pair of slopes carried by the carriage slot and extending through the carriage, one pair of slopes at each end of said slot and extending outwardly from the center of the carriage, whereby said other lever arm, by extending through the carriage, causes reciprocation of the same during movement in a circular path whereby said carriage is directly motivated in opposite directions during cyclic operation of the die press.
