PROVISIONAL SPECIFICATION.
Improvements in Back Sight Protectors for Rifles.
JOHN ELSDEN MARTIN Gunsmith 20 Exchange Square Glasgow and DAVID
REID Telegraph Mechanic 281 Dumbarton Road Glasgow do hereby declare the
nature of this invention to be as follows:-
The sight protector is made in two parts hinged together. The one part is made
so that the undersides slide on either side of the flap of backsight & between the
flap & bed of backsight. This holds the protector secure & covers the upper
portion of backsight.
The other part of the protector folds over, covering the remainder of backsight
& is kept in position by both parts clasping at each side.
We claim that this backsight protector lies flatter & holds tighter than the
patterns at present in use.

COMPLETE SPECIFICATION.
Improvements in Back Sight Protectors for Rifles.
We, JOHN ELSDEN MARTIN, Gunsmith, 20 Exchange Square, Glasgow, and
DAVID REID, Telegraph Mechanic, 281 Dumbarton Road, Glasgow, 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 relates to a protector for back-sights for rifles and it has for its
object to construct a simple and effective protector.
The sight protector is made in two parts hinged together. The one part is made
so that the undersides slide on either side of the flap of back-sight and between
the flap and bed of back-sight. This holds the protector secure and covers the
upper portion of back-sight.
The other part of the protector folds over, covering the remainder of back-sight,
and is kept in position by both parts clasping at each side.
And in order that our said invention may be properly understood we have here-
unto appended an explanatory sheet of drawings, whereon:-
Fig. 1 is a plan view of our protector.
Fig. 2 is a view looking from below.
Fig. 3 is a side view, and
Fig. 4 an end view.
Referring to the drawings:-
The protector consists of a piece of metal a to which is hinged, at b, a second
piece of metal c. The metal piece a is flanged over, on its underside, at d, d', so
as to slide over and catch on the back-sight. The metal is or may be also bent
over at the end e. The hinged cover piece c is simply dished so as to leave a wall
or rim around three of its sides the fourth side being flat and hinge-jointed to the
piece a. The hinge is, preferably, made to project up at the back of the protector
as shown at Figs. 1 and 3. At g and y¹ the wall of the cover c is bent inwards, as
shown more particularly at Figs. 2, 3, and 4, and to receive these bent parts grooves
or cuts h, h', are made in the sides of the picce a. By this arrangement, when the
cover is brought down level with the part a, as shown at Figs. 1 and 2, the parts g, g',

grip action the ends i, i, of the piece a arc, preferably, slightly bevelled.
With our improved protector the part a can be slid over the sight and then the
cover e pressed down and locked. The sight is thus securely protected. To take
off the protector, the cover is pressed upwards until the parts 7, g', override the
edges of the grooves h, h, when the protector can be casily taken off.
Fig. 3 shows the protector with the parts a, c, bent back to show the groove h
and in Fig. 4 the part a is bent back on the cover c so as to show the flanges d
and d¹.
Our improved protector lies flatter and holds tighter than the patterns at present
in use.
Having now particularly described and ascertained the nature of our said..
invention and in what manner the same is to be performed, we declare that what we
claim is :-
A back-sight protector for rifles made substantially as herein before set forth
with reference to the drawings annexed.
