The embodiments herein relate generally to firearms and ammunition accessories.
During the reloading of small arms ammunition process there is what's called a crimp on primers. When the primer is removed the crimp also need to be removed. That is achieved by either swaging process or cutting out the crimp. The swaging process is inconsistent and often not very effective. Embodiments of the disclosed invention solve this problem.
An ammunition reloading press primer reamer is configured to remove a primer crimp from a casing and straightening a pocket in the casing. The ammunition reloading press primer reamer has a spring arranged around a base body and arranged against a main body. A shuttle is inserted into the main body with a thrust bearing and held in place with a drilling cable. A tip is inserted into the shuttle and partially surrounded by a roller bearing. A press has a connecting rod attached to the adjustment bolt and joined to a crankshaft with a crankshaft cam. A casing holder is attached to the press and configured to hold a casing. A tool holding arm is attached to the press and further comprising a face plate attached with a plurality of screws. As the crankshaft is pulled down, the tip spins and cuts a beveled ream into the casing.
In some embodiments, an adjustment bolt can be threaded onto the base body with a lock nut. A retaining pin can join the base body to a slot the main body. The base body can laterally slide within the main body.
A housing back houses the main body and is joined to a housing front with a plurality of housing fasteners. An electric microswitch can be attached to the housing front with a plurality of screws.
A decapping die can be configured to remove a primer from a primer cavity in the casing. A vacuum attachment can evacuate the chips during cutting and cools the tip. Engaging the crankshaft can move the press one position and inserts the casing into the casing holder.
The detailed description of some embodiments of the invention is made below with reference to the accompanying figures, wherein like numerals represent corresponding parts of the figures.
By way of example, and referring to
A shuttle 22, is partially housed within the main body 20 with a thrust bearing 66. A drilling cable 38 is arranged through the shuttle 22. A tip 24 is joined to the shuttle 22 with a roller bearing 40.
A housing further comprises a housing back 28 joined to a housing front 30 with a plurality of housing fasteners 32. An electric microswitch 34 is joined to the housing front 30 with a plurality of screws 36. A drilling cable 38 is arranged through the main body 20 and is electrically coupled to a drive box.
A press 50 further comprises a crankshaft 52 arranged through a connecting rod 56 with a crankshaft cam 54. The press 50 further comprises a casing holder 58. The casing holder 58 holds a cartridge case 42. The cartridge case 42 further comprises a primer cavity 44 and a crimped edge 46.
A tool holding arm 60 is attached to the press 50 and is attached to a cover plate 62 with screws 64. A decapping die can be configured to remove the primer 46 from a primer cavity 44 in the casing 42. A vacuum attachment can evacuate the chips during cutting and cools the tip. Engaging the crankshaft 52 can move the press one position and inserts the casing 42 into the casing holder 58.
As used in this application, the term “a” or “an” means “at least one” or “one or more.”
As used in this application, the term “about” or “approximately” refers to a range of values within plus or minus 10% of the specified number.
As used in this application, the term “substantially” means that the actual value is within about 10% of the actual desired value, particularly within about 5% of the actual desired value and especially within about 1% of the actual desired value of any variable, element or limit set forth herein.
All references throughout this application, for example patent documents including issued or granted patents or equivalents, patent application publications, and non-patent literature documents or other source material, are hereby incorporated by reference herein in their entireties, as though individually incorporated by reference, to the extent each reference is at least partially not inconsistent with the disclosure in the present application (for example, a reference that is partially inconsistent is incorporated by reference except for the partially inconsistent portion of the reference).
A portion of the disclosure of this patent document contains material which is subject to copyright protection. The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent file or records, but otherwise reserves all copyright rights whatsoever.
Any element in a claim that does not explicitly state “means for” performing a specified function, or “step for” performing a specified function, is not to be interpreted as a “means” or “step” clause as specified in 35 U.S.C. § 112, ¶6. In particular, any use of “step of” in the claims is not intended to invoke the provision of 35 U.S.C. § 112, ¶6.
Persons of ordinary skill in the art may appreciate that numerous design configurations may be possible to enjoy the functional benefits of the inventive systems. Thus, given the wide variety of configurations and arrangements of embodiments of the present invention the scope of the invention is reflected by the breadth of the claims below rather than narrowed by the embodiments described above.
This application claims priority to provisional patent application U.S. Ser. No. 63/046,052 filed on Jun. 30, 2020, the entire contents of which is herein incorporated by reference.
