Claim 1
Independent Claim
243 words
A press including a body having an upwardly opening elongated and upstanding material compression chamber formed therein, upper and lower pressure pistons operable longitudinally in said chamber, support means supporting said upper piston for reciprocation between an upper position spaced above the upper end of said chamber and a lower position displaced downwardly into the upper end of said chamber, said support means also including means supporting said lower piston for movement in said chamber between a lower position and an upper position spaced thereabove and substantially flush with the upper end of said chamber, a material fill discharge outlet shiftable laterally of the upper end of said chamber between a first position disposed on one side of said chamber, a second position disposed in registry with the upper end of said chamber and a third position out of registry with and disposed to the remote side of the upper end of said chamber, and drive means operatively connected to said outlet and said pistons operable to sequentially (1) maintain the upper piston in its upper position while lowering the lower piston to its lower position and shifting said discharge outlet from its first position to its third position through its second position, (2) simultaneously raise said lower piston to an intermediate position spaced below the upper end of said chamber and lower said upper piston to its lower position, and (3) then raise said upper and lower pistons to their upper positions.
Claim 2
Dependent Claim
243 words
A press including a body having an upwardly opening elongated and upstanding material compression chamber formed therein, upper and lower pressure pistons operable longitudinally in said chamber, support means supporting said upper piston for reciprocation between an upper position spaced above the upper end of said chamber and a lower position displaced downwardly into the upper end of said chamber, said support means also including means supporting said lower piston for movement in said chamber between a lower position and an upper position spaced thereabove and substantially flush with the upper end of said chamber, a material fill discharge outlet shiftable laterally of the upper end of said chamber between a first position disposed on one side of said chamber, a second position disposed in registry with the upper end of said chamber and a third position out of registry with and disposed to the remote side of the upper end of said chamber, and drive means operatively connected to said outlet and said pistons operable to sequentially (1) maintain the upper piston in its upper position while lowering the lower piston to its lower position and shifting said discharge outlet from its first position to its third position through its second position, (2) simultaneously raise said lower piston to an intermediate position spaced below the upper end of said chamber and lower said upper piston to its lower position, and (3) then raise said upper and lower pistons to their upper positions.
Claim 3
Dependent Claim
59 words
The combination of claim 1 wherein said support means includes a pair of upper and lower beams pivotally supported intermediate their upper and lower ends for oscillation about vertically spaced generally parallel horizontal axes extending transversely of said beams intermediate their opposite ends, said pistons being connected to one pair of corresponding ends of said beams for oscillation therewith.
Claim 4
Dependent Claim
35 words
The combination of claim 2 wherein said drive means includes rotary cam means disposed between the other pair of ends of said arms and coacting cam follower means carried by said other pair of ends.
Claim 5
Dependent Claim
16 words
The combination of claim 1 wherein said material fill discharge outlet comprises a gravity flow outlet.
Claim 6
Dependent Claim
58 words
The combination of claim 4 wherein said body includes a generally planar upper surface portion upwardly through which Said chamber opens, said discharge outlet being slidingly engaged with said upper surface portion whereby the latter closes said discharge outlet to the discharge of material therefrom except when said outlet is registered with the upper end of said chamber.
Claim 7
Dependent Claim
75 words
The combination of claim 1 wherein said support means also supports said upper and lower pistons for oscillation about the center axis of said chamber, said drive means also including means operable to rotate said pistons in selected directions during upward movement of the lower piston to its intermediate position and the upper piston to its lower position and to rotate said pistons in the opposite directions during their subsequent movement to their upper positions.
Claim 8
Dependent Claim
20 words
The combination of claim 6 wherein said drive means for rotating said pistons includes means for inversely rotating said pistons.
Claim 9
Dependent Claim
71 words
The combination of claim 1 wherein said support means includes a pair of upper and lower beams pivotally supported intermediate their upper and lower ends for oscillation about vertically spaced generally parallel horizontal axes extending transversely of said beams intermediate their opposite ends, said pistons being connected to one pair of corresponding ends of said beams for oscillation therewith, said press including means adjustably limiting downward movement of said lower piston.
Claim 10
Dependent Claim
134 words
The combination of claim 1 wherein said support means includes a pair of upper and lower beams pivotally supported intermediate their upper and lower ends for oscillation about vertically spaced generally parallel horizontal axes extending transversely of said beams intermediate their opposite ends, said pistons being connected to one pair of corresponding ends of said beams for oscillation therewith, said drive means including rotary cam means disposed between the other pair of ends of said arms and coacting cam follower means carried by said other pair of ends, said rotary cam means being journaled for rotation about an axis generally paralleling said axes, whereby a plurality of side-by-side pairs of pairs of upper and lower beams may be actuated by means of a plurality of rotary cam means spaced along the same rotary shaft.
Claim 11
Dependent Claim
133 words
