Improvements in Bullets for Rifled Fire Arms.
I, SAMUEL CLINTON STEWARDSON, of Santa Anna, in the County of Coleman,
State of Texas, one of the United States of America, Stockman, do hereby declare
the nature of this invention and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement:
My invention relates to improvements in bullets for rifled fire arms.
It is a well known fact that when an ordinary rifle has been fired a dozen or
more times the inner surface thereof becomes foul and dry destroying the accuracy of
the arm and requiring the same to be frequently wiped out and cleaned. In order
to overcome this objection and to prevent the rusting of the inside of the barrel
I have devised an improved form of bullet, the same consisting of a lead projectile
of proper size having an opening leading into the rear end thereof and terminating
at a point adjacent to the centre of the projectile, a laterally projecting opening
extending entirely through the projectile, and a recess or cavity upon the outer
surface thereof located at a point near its rear end.
The invention is clearly illustrated in the accompanying drawings, in which,
Figure 1 represents a side elevation of a bullet constructed according to my
invention.
Figure 2 is a similar view taken at right-angles to Figure 1.
Figure 3 is a vertical longitudinal section, and
Figure 4 is a cross-section through the laterally extending opening.
Like reference numerals indicate like parts in the different views.
The bullet 1 is made of any suitable size and shape and has an opening 2
extending longitudinally thereof leading from the rear end of the bullet and
terminating at a point adjacent to its center. The said bullet is also provided with
a transversely extending opening 3 and has an external recess or cavity 4 there-
on which extends entirely around the outer surface of the bullet as clearly shown.
The openings 2 and 3 and the cavity are filled with heavy grease or other
lubricant, and when the same is discharged from the cartridge the said grease is
expelled from the bullet coating the inner surface of the barrel of the rifle with
a thin film of oil. Actual practice has demonstrated the face that a rifle may
be fired an almost indefinite number of times without becoming dry and foul
and destroying the accuracy of the same. Furthermore by the use of bullets
constructed according to my invention the inner surface of the barrel is at all
times coated with grease or oil preventing the rusting thereof. The necessity
for the constant cleaning of the barrel is thereby obviated. I have found that
ordinary beef tallow is the most effective lubricating material with which to fill
the openings 2 and 3 and the cavity.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
1. A bullet having a cavity upon its outer surface filled with grease or other
lubricating material.

page_text: 2. A bullet having a transversely extending opening in it filled with grease
or other lubricating material.
3. A bullet having a longitudinally extending opening in its rear end
terminating at a point adjacent to the center thereof, and a laterally extending
opening leading outwardly from the end of said longitudinal opening, the said
openings being filled with grease or other lubricating material, substantially as
and for the purpose described.
4. A bullet having a longitudinal opening leading from the rear end thereof and
terminating at a point adjacent to its center, a laterally extending opening leading
outwardly from the upper end of said longitudinal opening, and a recess or cavity
in the outer surface of said bullet, the said opening and said cavity being filled
with heavy grease or other suitable lubricating material, substantially as and
for the purpose described.
