PROVISIONAL SPECIFICATION.
Improvements in or connected with Small Arms.
We, LEWIS WELLS BROADWELL, and MURRAY HAINES DURST both of
71 Clapham Road, Surrey, Gentlemen, do hereby declare the nature of this
invention to be as follows:-
The objects of our invention are ;
1. To transform or alter the existing Martini-Henry, and other single loader to
a repeating or magazine rifle on the bolt system in combination with any suitable
magazine.
2. To utilize a breech magazine as a cut-off when a magazine arm has to be
used as a single loader.
By our invention, we discard the existing breech drop block and the mechanism
known as the Martini action, or other similar actions, for example, that known as
the Peabody, and alter the breech to take a sliding bolt, we bore out the Henry
barrel to a thin tube, and insert therein, a new barrel of reduced calibre having
attached to its rear end any suitable breech bolt mechanism fitted and fastened
within the old shoe or breech casing, and having a Broadwell-Durst automatic
magazine as described in the Specification of our prior Patent No. 7037 of the
year 1891, or one of any other form properly attached.
The new barrel may be made to fit exactly the enlarged calibre of the old one,
or it may be a little less in diameter and thus have an annular space between them,
as in the new German rifle.
We also produce a cut off by simply turning the magazine to bring a closed part
thereof at the top. This movement shuts off the supply from magazine and affords
a guide for cartridges into barrel when employed as a single loader.

COMPLETE SPECIFICATION.
Improvements in or connected with Small Arms.
We, LEWIS WELLS BROADWELL, and MURRAY HAINES DURST, both of
71 Clapham Road, Surrey, Gentlemen, 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 objects of our invention are;
1. The transformation or alteration of existing Martini-Henry and other single
loaders to repeating or magazine rifles on the bolt system and with reduced calibre
in combination with any suitable magazine.
2. To utilize a magazine as a cut-off when the arm has to be used as a single
loader.
In carrying out our invention, we discard the existing breech drop block and the
mechanism known as the Martini action, or other similar actions, for example,―
those known as the Peabody, the Remington, and substitute therefor a bolt action
of any desired pattern. We bore out the "Henry" or other barrel to a thin tube,
and insert therein a new barrel of the desired reduced calibre having attached to
its rear end any suitable breech bolt mechanism fitted and fastened within the old
shoe, or breech casing, and having attached thereto any suitable magazine but

page_text: preferably a Broadwell-Durst automatic magazine as described in the Specification
of our prior Patent No. 7037 of the year 1891 but the magazine of the service rifle
may be used if preferred as shown at Figures 6 and 7. The new barrel may be
made to fit exactly the enlarged calibre of the old one, or it may be a little less in
diameter, and thus have an annular space between them, shown in Figures 2
and 6.
When the Broad well-Durst automatic magazine is used, we produce a cut-off by
simply turning the magazine slightly in the chamber to bring a closed part thereof
at the top. This movement shuts off the supply from the magazine, protects its
interior from dust or moisture, and affords a guide for cartridges into barrel when
employed as a single loader.
Figure 1 is a section of the transformed arm, and A is the bolt action fitted
within the old shoe or breech casing B of the Martini-Henry rifle. C (Figure 2)
is the recess cut in the sides of said old shoe to receive the Broadwell-Durst
automatic magazine. D is the trigger guard combined with the elongation E
hinged at F, and closed at G, thus supporting and protecting the magazine.
Figure 1 also shows the manner in which the new barrel H of reduced calibre is
located within the old one I, the calibre of which has been enlarged to receive it,
and how the breech action is attached to the new barrel.
Figure 2 is an elevation of the same arm.
Figure 3 is a cross section through the breech at rear end of magazine showing
it in position for feeding its cartridges up to the bolt at J.
Figure 4 is a similar section showing the magazine cut-off by having been turned
slightly to the left, thus covering the opening of the magazine, and thereby
presenting a smooth and uninterrupted guide for the cartridges into the loading
chamber when the arm is to be used as a single loader. a, a, in both figures are
the small projections which serve as grips for turning the magazine, being a
sphere for engaging in recesses c to temporarily lock the magazine.
Figure 5 is a top view showing the new bolt mechanism within the old shoc.
Figure 6 is a longitudinal central section showing the transformation adapted to
the use of the flat magazine similar to that employed in the Lee-Speed and other
repeaters.
Figure 7 is a cross section of the same through L, M.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The novel combination of known parts and devices for the novel purpose of
transforming the Martini-Henry rifle, and other block systems to repeaters, or
magazine rifles with bolt breech loading action and reduced calibre, substantially as
above described.
2. The reduction of calibre by means of boring out the old barrel to a thin tube
and inserting therein a new barrel of reduced calibre in the manner as described
and illustrated.
3. The manner of producing the cut-off, when employing the Broadwell-Durst
automatic magazine by simply turning it, and thus be able to employ the arm as a
single loader.
