1. A trimmer for cartridge cases comprising:
a base;
a bearing housing mounted to said base;
a shaft inserted into said bearing housing;
means for holding said shaft within said bearing housing attached to said shaft;
a cutter assembly mounted to said shaft, said cutter assembly further comprising a notched cutter with a first cutting edge for an inside chamber, a second cutting edge for length, and a deburring edge arranged so three distinct cuts are made on the mouth of said cartridge case;
a case holder housing mounted to said base with an opening axially aligned with said shaft;
a cartridge case holder mounted within said case holder with an opening shaped to match said cartridge case’s external dimensions and a shoulder stop for indexing on the shoulder of said cartridge case;
means for turning said shaft;
a flywheel flush mounted to said shaft further comprising a slot that allows said notched cutter to extend through said flywheel assembly such that said flywheel assembly does not prevent said notched cutter’s edges from cutting said cartridge cases, means to mount said notched cutter to said shaft, and at least one set screw in said flywheel assembly which fits within said notch such that cutting pressure when said trimmer is in use causes said notched cutter to resist wobbling due to said set screw filling said notch.
2. A trimmer for cartridge cases as described in claim 1 further comprising a notched support plate mounted beside said notched cutter;
a guide mounted to said notched support plate to hold cartridge case neck in a desired position relate to said notched cutter and also serves as an outside deburring edge for said cartridge case; and
the notch in said notched support plate aligned with at least one of said set screws in said flywheel such that said set screw may pass completely through said flywheel and into said notch in said notched support plate.
3. A trimmer for cartridge cases as described in claim 2 further comprising two aligned set screws which fit into notches on said notched cutter so that in addition to holding said notched cutter in position they also allow said notched cutter to be shifted as desired; and
two aligned set screws which fit into notches in said notched support plate so that in addition to holding said notched support plate in position they also allow said notched support plate to be shifted as desired.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
Having described my invention in such terms as to enable those skilled in the art to understand and practice it, and having identified the presently preferred embodiments thereof, I claim:
1. Pitching apparatus for simulating a plurality of different pitches, said apparatus including
(a) a plurality of pitching machines, each including means for engaging and propelling a ball through the air to simulate at least a first kind of pitch and a second kind of pitch, each of said pitching machines being adjustable between at least two operative positions,
(i) a first operative position for delivering said first kind of pitch, and,
(ii) a second operative position for delivering said second kind of pitch; and,
(b) mounting means including a common base for said pitching machines to move each of said pitching machines between
(i) a first delivery position from which a ball is propelled from the pitching machine through the air, each of said pitching machines occupying a selected space on said base when in said first delivery position,
(ii) a second standby position different than said first delivery position, each of said machines when moved to said second standby position being moved on said base completely out of said selected space such that another of said machines can be moved into and occupy said selected space; and,
(c) means for obscuring each of said pitching machines when said pitching machine is in said first delivery position such that a batter is unable to discern the orientation of said pitching machine in said first delivery position.
2. Pitching apparatus including
(a) a plurality of pitching machines, each including means for engaging and propelling a ball through the air; and,
(b) mounting means including a common base for said pitching machines to move each of said pitching machines between
(i) a first delivery position from which a ball is propelled from the pitching machine through the air, each of said pitching machines occupying a selected space on said base when in said first delivery position,
(ii) a second standby position different than said first delivery position, each of said machines when moved on said base to said second standby position being moved completely out of said selected space such that another of said machines can occupy said selected space; and,
(c) means for obscuring each of said pitching machines when said pitching machines are in said first delivery position such that a batter is unable to discern the orientation of said pitching machine in said first delivery position.
3. A method for propelling a ball through the air for a batter to hit, including the steps of
(a) providing a plurality of pitching machines each including means for engaging and propelling a ball through the air, one of said pitching machines being operable to deliver a first kind of pitch and another of said pitching machines being operable to deliver a second kind of pitch; and,
(b) mounting each of said pitching machines on mounting means to move each of said pitching machines on a common base between
(i) a first delivery position from which a ball is propelled from the pitching machine through the air, each of said pitching machines occupying a selected space on said base when in said first delivery position, and
(ii) a second standby position different than said first delivery position, each of said machines when moved on said base to said second standby position being moved completely out of said selected space such that another of said machines can occupy said selected space;
(c) providing obscuring means for positioning to obscure each of said pitching machines when said pitching machine is said first delivery position such that a batter is unable to discern the orientation of said pitching machine in said first delivery position;
(d) positioning said obscuring means to obscure each of said pitching machines when said pitching machine is in said first delivery position;
(e) moving said one of said pitching machines to said first delivery position and into said selected space;
(f) operating said one of said pitching machines to deliver said first kind of pitch to the batter;
(g) moving said one of said pitching machines out of said selected space;
(h) moving another of said pitching machines to said first delivery position and into said selected space; and,
(i) operating said another of said pitching machines to deliver said second kind of pitch to the batter.
