Complete Specification Left, 16th Apr., 1892-Accepted, 11th June, 1892
PROVISIONAL SPECIFICATION.
Improvements in Breech Bolts for Rifles.
I, RICHARD MORRIS of Bennett Park, Blackheath in the County of Kent,
Engineer, do hereby declare the nature of this invention to be as follows:-
When the bolt of a rifle is moved forwards, it has to be turned partly round so as
to bring a projection from its side or two such projections in front of a stop or stops
which hold the bolt in its forward position during the firing, and, before the bolt
can be drawn back, it must be turned backwards to clear these stops.
When the extractor is fixed to the end of the bolt it has to turn with it, which
may be considered objectionable as it involves a wide chase in the breech of the
barrel. Sometimes in order to avoid this turning of the extractor, it is fixed to a
head piece pivotted on the end of the bolt, this involving certain complexity and
weakening of the parts.
My invention relates to means of connecting the extractor to the bolt in such a
manner that it is moved with certainty to and fro along with the bolt but without
turning, as I shall describe referring to the accompanying drawings, which shew my
invention applied to a bolt having at its front two side projections or ears fitted to
enter recesses on turning the bolt partly round.
Fig. 1 is a side view and Fig. 2 is a longitudinal section of the front end of the
bolt with the extractor attached ;
Figs. 3 and 4 are transverse sections respectively on X X and Y Y of Fig. 2
looking towards the front.
Fig. 5 is a side view of the extractor shewn separate.
B is the body of the bolt and E E its two cars. Immediately behind these ears
I turn part of the bolt to a somewhat smaller diameter on which I spring a part,
Romewhat more than a semicircle, of a steel ring R, which has a lateral projection A
and another projection C with an internal groove.
The extractor D is made with an elastic tail piece d which fits into the
groove of C and it is notched down at e to allow one of the ears E to turn freely
through the notch.
The ring R and consequently the extractor is prevented from turning when the
bolt B is turned, by the projections A and C bearing against the sides of the chases
along which the ears E E move when the bolt is advanced and retracted. The tail
piece d forms the spring for the extractor, certain freedom being provided for the
movement by a notch in the front edge of the ring R.
In cases where the bolt has no cars E in front, but has a projection farther back,
the extractor does not need to have the deep notch e.

Improvements in Breech Bolts for Rifles.
I, RICHARD MORRIS, of Bennett Park, Blackheath, in the County of Kent,
Engineer, 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 :-
When the bolt of a rifle is moved forwards, it has to be turned partly round so as
to bring a projection from its side or two such projections in front of a stop or stops
.

can be drawn back, it must be turned backwards to clear these stops.
When the extractor is fixed to the end of the bolt it has to turn with it, which
may be considered objectionable as it involves a wide chase in the breech of the
barrel. Sometimes in order to avoid this turning of the extractor, it is fixed to a
head piece pivotted on the end of the bolt, this involving certain complexity and
weakening of the parts.
My invention relates to means of connecting the extractor to the bolt in such a
manner that it is moved with certainty to and fro along with the bolt but without
turning, as I shall describe referring to the drawings accompanying my Provisional
Specification which shew my invention applied to a bolt having at its front
two side projections or ears fitted to enter recesses on turning the bolt partly
round.
Fig. 1 is a side view and Fig. 2 is a longitudinal section of the front end of the
bolt with the extractor attached ;
Figs. 3 and 4 are transverse sections respectively on X X and Y Y of Fig. 2,
looking towards the front.
Fig. 5 is a side view of the extractor shewn separate.
B is the body of the bolt and E E its two ears. Immediately behind these ears
I turn part of the bolt to a somewhat smaller diameter on which I spring a part,
somewhat more than a semicircle, of a steel ring R, which has a lateral projection A
and another projection C with an internal groove.
The extractor D is made with an elastic tail piece d which fits into the groove
of C and it is notched down at e to allow one of the ears E to turn freely through
the notch.
The ring R and consequently the extractor is prevented from turning when the
bolt B is turned by the projections A and C bearing against the sides of the chases
along which the ears E E move when the bolt is advanced and retracted. The tail
piece & forms the spring for the extractor, certain freedom being provided for the
movement by a notch in the front edge of the ring R.
In cases where the bolt has no ears E in front, but has a projection farther back,
the extractor does not need to have the deep notch e.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
In combination with a rifle bolt, a part ring to hold the extractor sprung on a
reduced part of the bolt and provided with stops to prevent it from turning with the
bolt, substantially as and for the purposes set forth.
