UNITED STATES A Patented January 26, 1904.
PATENT ENCE.
PRIMER.
SPECIFICATION forming part of Letters Patent No. 750,624, dated January 26, 1904.
Application led February 12, 1908.` Serial No. 143,050. (No model.)
To aJZZwhom it may concern.-
Be it known that I, JOHN M. EDMUNDS, a citizen of the United States, residing in New York, in the county of New York and "State of New York, have invented certain new and useful Improvements in Primers, of` which the following is -a specification.
` This invention relates' to primer-caps for projectiles, and has for its object to produce an inexpensive andeficient'structure.
In the accompanying drawings, forming a part of this specification, Figure 1 is a sectional view of a. primer-cap. Fig. 2 is an elevational view ofthe same. Fig. 3 is a perspective view of the bridge or anvil Vused in said Similar characters of reference indicate like cap. v
parts throughout the gures.
The primer-plug comprises a cap 4, having an extended iiange 5. In the bottom of the recess 10 ofthe plug is a socket '11, which receivcs the fulminate 12. This socket 11 is suf# ticiently deep to reduce the thickness of the cap 4 at 13, so that the portion 13 will be suf# ficicntly thin to impart the blow from the hammer of the gun tothe fulminate'12.
` For the purpose of holding the fulminate 12 in place I provide a bridge or anvil 14, which is notched or otherwise formed, as at 15, so as to form exits for the escape of the -fire when the explosion occurs so that it may reach the powder. This bridge or seat is preferably pressed into place during the manufacture? of the primer-plug. Y
It will be understood that I do ynot limit my invention to the construction herein 'shown and that other modifications may be resorted to within thep'urview o f said invention.
Having. thus described my invention,. I`
claim- U U l. A primer-plug for pro] ectlles comprising a member provided with an annular, recess a pocket formed in the base` thereof and adapted to contain a fulminate and a bridge or anvil fitted into said pocket for holding said ful- 45 minatefin place.
2. -A primer-plug for projectiles comprising a member provided withl an annular recess a pocket formed in the'base thereof and adapted to contain a fulminate and a perforated bridge 50 or anvil fitted into said pocket for holdingsaid fulmina in place. r f
3. A primer-cap for projectilescomprising a head provided with a pocket to receive a fulminate said pocket being 'suiiiciently deep to 55 materially reducel the thickness ofthe head,\ a fulminatein said-pocket and a perforated bridge pressed into the pocket and upon the fulminate.
4. A primer-cap for projectiles comprising 60 a member having an annular recess, a portion of the wall of which is thin whereby to readily impart a' blow to a fulminate and an anvil secured in said recess for holding the fulminate in place. Y
5. A primercap for projectiles comprising a memberprovided rwith a recess a seat within said -recess adapted to receive a fulminate, a
thin partition at the seatportion to receive and impart the 4blow to the -fulminate from 70 the hammer and a perforated anvil secured within the recess for receiving the blow.
6. A primer-cap for projectiles comprising a member provided with arecess, aseat within said recess adaptedto receive' a fulminate, a 75 thin partition at-the seat portion to receive and impart the blow to/ the fulminate from the hammer 'and an anvil secured within the JOHN M. EnMUNDs.
