The Table Top Priming Machine uses a unique rotary disk assembly to hold cases as the machine installs primers into the cases. Gravity assists with securing cases in the disk assembly and promotes ejection of the finished cases. The compact construction of the machine makes the machine accessible for individuals or manufactures with limited space to create consistent ammunition at high speeds with limited space. Furthermore, the machine's design allows for any end user to assemble and maintain the machine with general hand tools, which obviates the need for specialized maintenance from the manufacturer. ## Claims ### Claim 1 A Table Top Priming Machine comprising: a. a means to feed a plurality of cases to a rotatory disk assembly; b. a means to feed a plurality of primers to said rotatory disk assembly; c. a means for said rotary disk assembly to insert said primers into said cases; and d. a motor, which rotates said disk assembly. ### Claim 2 (depends on 1) The Table Top Priming Machine of claim 1 where said rotatory disk assembly is mounted at a 45 degree angle. ### Claim 3 (depends on 1) The Table Top Priming Machine of claim 1 where said rotatory disk assembly is comprised of a top disk, extractor disk, flange disk, case disk, nest disk, pin disk, and threaded pin disk. ### Claim 4 (depends on 3) The Table Top Priming Machine of claim 3 where said top disk is further comprised of a staking pin assembly, and at least one eject pin. ### Claim 5 (depends on 3) The Table Top Priming Machine of claim 3 where said extractor disk is further comprised of a plurality of extractor disk pockets of the perimeter of said extractor disk. ### Claim 6 (depends on 3) The Table Top Priming Machine of claim 3 where said flange disk is further comprised of a plurality of flange disk pockets on the perimeter of said flange disk. ### Claim 7 (depends on 3) The Table Top Priming Machine of claim 3 where said case disk is further comprised a plurality of primer locating holes to center said primers in said cases. ### Claim 8 (depends on 3) The Table Top Priming Machine of claim 3 where said nest disk is further comprised of a plurality of nest disk pockets on the perimeter of said next disk, which retain said primers until said primers move to a staking station. ### Claim 9 (depends on 3) The Table Top Priming Machine of claim 3 where said pin disk guides a staking pin into other disks of said disk assembly to push said primers into said cases. ### Claim 10 (depends on 3) The Table Top Priming Machine of claim 3 where said threaded pin disk is further comprised of a plurality of cam features on the perimeter of said threaded pin disk, which actuate a cam follower of a case feed arm. ### Claim 11 (depends on 3) The Table Top Priming Machine of claim 3 where said threaded pin disk is further comprised of a connection means to a spindle, which is connected to said motor. ### Claim 12 (depends on 3) The Table Top Priming Machine of claim 3 where said top disk, extractor disk, flange disk, case disk, nest disk, pin disk, and threaded pin disk are all comprised of at least one threaded hole to accommodate at least one dowel through said at least one threaded hole to sandwich said disks together when bolted. ### Claim 13 (depends on 1) The Table Top Priming Machine of claim 1 where said means to feed a plurality of cases to a rotatory disk assembly is comprised of a collator, a case rotator, and caliber specific case tube. ### Claim 14 (depends on 1) The Table Top Priming Machine of claim 1 where said means to feed a plurality of primers to said rotatory disk assembly is comprised of a vibratory bowl, tube, track feed, and swing arm. ### Claim 15 (depends on 1) The Table Top Priming Machine of claim 1 where said means for said rotary disk assembly to insert said primers into said cases is comprised of a stake finger, a spring loaded staking pin, and an adjustable stake plate. ### Claim 16 (depends on 1) The Table Top Priming Machine of claim 1 where said motor is coupled to a spindle by a clutch whereas said spindle rotates in a hub mounted to a spindle plate and said spindle is connected to said disk assembly with a key. ### Claim 17 (depends on 1) The Table Top Priming Machine of claim 1 where said Table Top Priming Machine is capable of priming up to 50 rounds per minute.
