We HUGH ADAMS SILVER of Sun Court, Cornhill, London, Merchant and Manufac-
turer and WALTER FLETCHER of the same place, Gunsmith, do hereby declare the
nature of our said invention to be as follows:-
The object of this invention is to construct or form the foresights of Revolvers,
Rifles and other like fire arms of a combination of Metal and Ivory in a special
manner.
The employment of Ivory as we propose has the following advantages
1. It is always prominent to the eye of the firer for taking aim.
2. It can be so placed as to be protected from injury during Military or other
exercisc.
3. It is not affected by exposure.
4. It can be easily cleaned.
5. It is not readily stained or discoloured by ordinary care.
6. It can be easily renovated if scratched.
7. It can he made to any desired size and be kept permanently so.
For the purpose of our invention we make the metal part preferably of steel with a
tapered or parallel hole in the back face within or just below the knife edge or of an
angled or a rounded top edge said hole being sunk preferably a little larger at its
neck. Into this hole we cement an ivory pin, stem, stud, or button with the outer
end rounded off and sunk within the face of the metal or be flush therewith or to
project slightly.
Instead of the ivory pin, stem stud or button being cemented in the hole of the
metal fore sight it may be screwed in or be otherwise affixed,

page_text: We are aware that Ivory has been already used with metal foresights of fire arms
but it has only been used as tips, in slots or temporarily attached, and subject to all
the wear and tear of the arm during cleaning, oiling etc. and it has consequently
become useless in a short time.
We are also aware that Ivory foresights have been employed with Fire arins.
Therefore our invention is not the bare application of Ivory as a sighting point to the
foresight of a fire arm, but to the combination of Ivory and metal in the manner
hereinbefore described the ivory being permanently fixed, clear to the eye at all times
and reliable as a sighting point as set forth.
We have mentioned Ivory, which is the best material for our purpose, but any good
substitute, such as the compositions known as Xylonite, Lionite, Parkesine or the like,
could be used for our pins etc.

We have mentioned ivory which is the best material for our purpose but any good

Four examples of our invention are shown in the annexed drawings, a is the ivory
(or other equivalent material) stud, button, or spot piece let into the face of fore-
sight 6 by screwing or otherwise, c is the barrel of the gun.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed, we declare that we claim is
:-
The employment of an ivory (or its equivalent) stud, pin, or spot piece a in the
fore-sight of a revolver, rifle or other like fire-arm cas and for the purposes set
