to be as follows:-
An instrument or apparatus in the form of a tube, fitted with a reflector at the
breech end, or a reflector on a piece of metal or other substance fitting tightly in
or on the action of the Rifle. The reflector, which may be of glass or polished
metal is attached at such an angle as to reflect the rifling from breech to muzzle or

I WILLIAM JACKMAN JEFFERY of 226 Strand, London in the County of
Middlesex, Gunmakers Salesman 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:—
This invention is designed for the purpose of inspecting the barrels of Rifles and
other firearms. The apparatus or appliance is inserted into the breech of the Rifle
or other firearm, the muzzle then being directed towards a light and then the
reflection of the rifling and bore of the barrel is shown on the mirror which is
fitted in or on the said instrument or apparatus, thus enabling the chamber and
rifling to be examined to show whether rust, leading or dirt has accumulated in
the cartridge chamber or grooving and rifling of the rifle.

In these drawings A represents the metal case or body part of the apparatus,
B. the oval shaped glass or polished metal mirror, which is set at an angle of about
45° to the axis of the apparatus, C. shows the nose or nozzle which is inserted at
its front end into the cartridge chamber of the rifle, and its other end is cut at an
angle corresponding to that at which the mirror is set & forms a stop for retaining
the mirror in its proper position, D. represents a small screw which secures the
nozzle part C. to the body part A.-E. E. are eyes fastened to the end of the
apparatus & its case for the purpose of attaching a chain to for connecting
the apparatus and case together-F represents a metal cap which forms a
protecting casing for the instrument guarding it from damage & dust.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The construction of an instrument apparatus or appliance for inspecting or
examining the insides & cartridge chambers of Rifles.
2. The apparatus, instrument or appliance can be used in other breech loading
fire arms.
