for Rifles, Machine Guns, and Ordnance.
DANIEL FRASER Gun & Rifle Maker 4 Leith Street Terrace Edinburgh in the
County of Midlothian do hereby declare the nature of this invention to be as
follows:-
The first part of my Invention has for its object the further improvement of
Telescopic Sights.
Whereas Sights of this class are objectionable owing to the small field of view,
especially at near distances, rendering it difficult to find the object aimed at and
more particularly if that object is in motion. I have by means of an arrangement,
of the various lenses, secured a larger field than has hitherto been attainable and
I have thus obviated the necessity for placing the eye of the firer close to the eye-
piece. My system also permits of a compact and useful size of Sight.
The Second part of my Invention consists of an improvement in focussing of said
Telescopic Sight, whereby the focus may be adjusted to suit any peculiarity of vision
without danger of alteration at any time from accidental outward contact such as
might occur in stalking game.
The Third part of the Invention consists in placing the Aiming lines in front
of the first or lens nearest the eye, thereby securing a greater radius between the
points of aim, that is, between the aiming lines and the object lens. This arrange-
inent has the effect of making the sight less sensitive and consequently more
accurate than was possible on the original system where the lines were placed in
front of the fourth lens from the eye; while stronger lines may be used as they are
not magnified to the same extent.
The Fourth part of my Invention has reference to the method of focussing the
said lines and the means by which they are attached to the line disc.
The Fifth part of the Invention refers to an improved system of putting together
the Barrels of Double Rifles. With a view to obviate or counteract the effect of
the flip or outward throw given to each Barrel when fired and which is due mainly

page_text: to the packing between the barrels and the ribs, I make the muzzle of each barrel
project one half inch more or less. This plan admits of the muzzles being secured
by one solid piece of metal instead of the many small pieces of packing usually
adopted. It also allows of the muzzles being cut and renewed, when by constant use
they wear wide, without injury to the accuracy of the weapon.
The Sixth part of my Invention refers to an improved direct Striker particularly
adapted to Single Rifles of the Hammerless class; the providing a bracket to carry
the mainspring when the latter is placed under the barrel to admit of the barrel
being detached and a blocking or intercepting Safety Bolt to prevent the Hammer
being jarred out of the bent by a sudden blow on the butt or other part of the
rifle.

for Rifles, Machine Guns, and Ordnance.
DANIEL FRASER Gun & Rifle Maker 4 Leith Street Terrace Edinburgh in the
County of Midlothian 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:
The First part of my Invention has for its object the further improvement of
Telescopic Sights. Whereas Sights of this class, are objectionable owing to the small
field of view, especially at near distances rendering it difficult to find the object
aimed at and more particularly if that object is in motion.
I have by means of an arrangement of the various lenses, secured a larger field
than has hitherto been attainable and I have thus obviated the necessity for placing
the eye of the firer close to the eye-piece.
My system also permits of a compact and useful size of sight.
The Second part of my Invention consists of an improvement in focussing of said
Telescopic Sight whereby the focus may be adjusted to suit any peculiarity of vision
without danger of alteration at any time from accidental outward contact such as
might occur in Stalking game.
The Third part of my Invention consists in placing the aiming lines in front of the
first or lens nearest to the eye, thereby securing a greater radius between the points
of aim, that is between the aiming lines and the object glass or lens. This arrange-
ment has the effect of making the sight less sensitive and consequently more accurate
than was possible on the original system where the lines were placed in front of the
fourth lens from the eye; while stronger lines may be used as they are not magnified
to the same extent.
The Fourth part of my Invention has reference to the method of focussing the said
lines and the means by which they are attached to the line disc.
The Fifth part of the Invention refers to an improved system of putting together
the barrels of Double Rifles. With a view to counteract or obviate the effect of the
Hip or outward throw given to each barrel when fired and which is principally due to
the packing between the barrel & ribs, I make the muzzle of each barrel project one
half inch, more or less. This plan admits of the muzzles being secured by one solid
piece of metal instead of the many small pieces of packing usually adopted. It also
llows of the muzzles being cut and renewed (when by constant use they wear wide)
vithout impairing the accuracy of the weapon.
The Sixth part of my Invention consists of an improved direct striker adapted to
Single rifles of the Hammerless class, also a bracket to carry a mainspring when
lace underneath the barrel, to admit of the Barrel being detached.
The Seventh part of the Invention has for its object the prevention of accidental
premature discharge in the case of rifles belonging to the class last referred to, and
accomplish this by providing a blocking Safety bolt which is put into position by
e breech block and released by pulling the trigger.
In order that my said Invention may be properly understood, I now proceed to
escribe the manner in which the same may be used or practically carried out, making
ference to the accompanying Drawings and to the Figures & letters marked thereon.

page_text: Figure 1. shews the tube into which the object lens is set, the said tube being
divided and having an inner tube or ferrule solid with the outer or object lens end.
On releasing the pinching screw the focus may, be adjusted by elongating or con-
tracting this part when it is secured against any alteration due to the recoil of the rifle
by means of the said pinching or set screw.
Figure 2. represents the position of the line disc in the eye piece.
Figure 3. illustrates the means adopted for the adjustment of the aiming lines, an
arrangement similar in its application to that used in the focussing of the object lens
slide as shown in Figure 1.

In Figure 4. the line disc is represented with the lines in position. The face or 1
rim of the disc is recessed to receive both the upright and lateral lines which are
drawn over the edge and secured by a fine thread tied round the hollow part A.
The method used in constructing the barrels of double rifles and Fowling pieces is
shown in Figure 5. After the barrels are carefully laid and regulated, a block of
metal is inserted between and soldered to each barrel, the muzzles being allowed to
project more or less, the upper rib being also attached to the said metal block, thus
ensuring great strength and rigidity at the muzzle.
Fig. 6. applies more particularly to the Actions of Single barrelled rifles on what is
known as the vertical drop block system. In this case the striker is direct in its
action instead of being placed obliquely or working at an angle as usual. The
improved striker B. is inserted from the rear part of the breech block C. where it is
held in position by the screwed nut D. the said striker being recessed or hollowed on
the under part to allow of the nose of the hammer E. delivering the blow near its
centre.
The mainspring carrier F. obviates the necessity for cutting the barrel to receive
studs or dovetails and admits of the barrel being readily detached.
A blocking safety bolt is shown in Figs. 6 and 7. where a bell crank lever L is
attached to the trigger plate H. One arm N of the lever is operated by the falling
block G. the other arm being brought over the face of the hammer E. and only
relieved by pulling the trigger I. The blocking bolt is placed in the safe or locked
position by means of a wing or projection M on the descending breech block G.
coming in contact with an inclined plane N on the outer end of the bell-crank lever L
thus forcing the reverse end of the lever across the upper side of the hammer E when
at full cock..
The hammer E is released by the action of a rod O moved by the trigger 1. and
engaging with the lever L near its centre.
The action of pulling the trigger removes the overlapping arm of. the lever and the
hammer is left clear.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
1 claim is
First The improvement of what are known as Telescopic rifle sights by simplifying
the focussing arrangements of the object lens and of the line disc contained in the
eye slide, also in regard to the position of said disc, also in the mode of fixing the
said lines.
Second An improved method of constructing the barrels of double rifles and
fowling-pieces as before described.
Third The provision of an additional safety-bolt for single-barrelled rifles
rendering the arms secure against premature discharge, also improvements in th
mechanism used to explode the cap.
