T. M; WALLIS SUPPLEMENTARY BARRELS FOB. REVOLV'ERS.
Patented 0ct.31, 1878.
THGMAS M. WALLIS, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF. ONE-HALF HIS RIGHT TO WILLIAM WURFFLEIN, OF SAME PLACE.
HWIFRQJEMENT lN-SUPPLEMENTARY ARRELS FOR REVQLVER Specification forming part of Letters Patent No. iiet,9$3, dated October 31, 1876; application filed October 19, 1876.
To all whom t't may concern:
Be itkncwn that I, THOMAS M. WALLIS, of Philadelphia, Pennsylvania, have-invented an Improvement in Fire-Arms, of which the following is a specification:
The object of my invention is to render a revolver available for long-range pistol or rifle practice, without detracting from its utility as an ordinary revolver; and this object I at-- tain in the manner which I will now proceed to describe, reference being had to the accompanying drawing, in which- Figure 1 is a perspective view, showing the 'difi'erent parts required in carrying out my invention; Fig. 2, a view of part of the fire-.,
arm when arranged for use as an ordinary revolver; Fig. 3, part of the fire-arm arranged for rifle practice, and Fig.- 4 a section on the line 12 0t the'snpplemental barrel, (Shown in Fig. 3.)
The revolver A differs from those of ordinary construction in three respects only, the
' first being the absence fro'm'the end of the barrel of the usual projecting sight; the sec ond is the formation on the main barrel M of the threaded enlargement a extending a short distance from the end b of the frame; and the third is a threaded orifice, e, in the handle,
.for rcceivin g the threaded end f of the skeletonstock B, of the shape or approximating to the shape of an ordinaryrifle-stock.
When the weapon has to be arranged for rifle practice, a long tube or supplementary barrel, D, threaded internally at the rear end, is screwedonto the threadedenlargement a of the barrel M. The outer end of the tube D is furnished with a sight, h, properly ar-- ranged, in connection with the sight .1, for long-range practice.
. I prefer to lock the tube or supplementary barrel D to the frame of the revolver by means of the basepin H, in the manner shown in Figs. 3 and 4, the tube having on the under side a projection, m, in which is a recess adapted to the base-pin, which thus serves-as alock to maintain the supplementary barrel in its proper position.
Before the barrel can be unscrewed from. the ordinary barrel it will be necessary to withdraw the base-pin. In like manner the latter I must be detached before the supplementary.
barrel can be reattached to the main barrel. When the long supplementary barrel is thus secured to the revolver, the weapon may be used for long range pistol practice; or, by connecting the skeleton rifle-stock Btothat ordinary rifle..
When the weapon has to be used as a revolver, a short supplementary barrel, G, carrying at its outer end the usual sight IL, may be screwed onto the threaded enlargementa,
as shown in Fig.2. a a It is not essential that the supplementary barrels should be secured to the Iiiain barrel by a screw-thread. as other well-known modes of attachment-the ordinary welLknown baywith a stop or sight, h,- and the breech-pin H,
adapted to a recess in the said barrel, all substantially as specified.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
