Improvements in Apparatus for Cutting Wads, and for similar
Purposes.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, 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 :-
My invention has for its object the cutting of wads for shot gun cartridges,
such cutting being accomplished with greater cleanness and accuracy than has
heretofore been obtained.
In the following description I have set forth in detail, certain mechanism
embodying the invention; such means constituting but one of various mechanical
forms in which the principle of the invention may be used.
-
In the accompanying drawings :-
Figure I represents a side elevational view of my improved cutter illustrating a
form designed for the application of hand power.
Figure II represents a front elevation.
Figure III represents a partial vertical central transverse sectional view of the
mechanism as illustrated in Figure I.
Figure IV represents an enlarged and exaggerated axial sectional view of the
cutter proper.
Figure V represents a similar view of a modified form of said cutter.
Figure VI represents a similar view of a second modification.
Figure VII represents a partial vertical central transverse sectional view of the
mechanism embodying the modification of the cutter proper shown in Figure VI.
Figure VIII represents a horizontal cross-sectional view taken upon line 8-8 of
Figure VII; and
Figure IX represents a detail view illustrating one stage in the cutting operation
on a piece of wad material.
A cutter member A is suitably mounted in a retractible carriage B sliding upon
The
guide C and operated by a hand lever D, and is formed with a central bore a.
outer surface of the lower end of said cutter member is given a conical or bevel
surface a¹, inclining downwardly toward the cutter axis; the inner surface of the
said end is also given the form of a conical or bevel surface forming a cutting
surface a², inclining upwardly toward said axis, the said axis being coincident with
the cone axes. The said two surfaces intersect in a circle, the surface a² therefore
terminating in a cutting edge a³.
A plug E of cylindrical form is secured in the lower part of the machine frame
and projects perpendicularly into an aperture ƒ formed in a table portion F of the
said frame. The upper surface or base of said plug is located in the plane of the table
surface and the plug axis is in the same straight line with the axis of cutter
member A. The upper edge e of the plug forms a circular cutting edge whose

page_text: diameter is less than that of a circle having the edge a³ for its circumference and
greater than that of a circle having the upper extremity of said surface for its
circumference.
The plane of edge e is made perpendicular to the plug axis and the direction of
the motion of the upper member A is parallel to said axis.
The downward movement of the carriage may hence cause the surface a² to
impinge upon the edge e, the edge a passing through the plane of said edge e.
In the operation of the cutter illustrated in Figure IV, the edge a³ passes through
the wad material as shown in Figure IX. The distance of projection below the plane
of edge e is such that the edge as completely severs the material. Such severing
occurs before the surface is caused to impinge upon edge e and on examination of
the wad it is found that the lower edge has not been cleanly cut, but on the contrary
exhibits a shredded or ragged appearance. The surface a² now impinging upon the
edge e, such ragged or shredded portion projecting beyond edge e is cleanly cut off
thus leaving the entire surface of the wad even and smooth.
In practice the difference in diameter between the plug and the bore a is made
very small so that the wads may be successively pushed up through cutter
member A as shown in Figure III, with little compression..
Where it is desired to apply my invention to the cutting of smooth holes, the form
of the member A is varied as shown in Figure V and a die G having a cutting edge g
is introduced in the table F, the operation being the same as above described,
the edge g taking the place of edge e of the plug.
When it is desired to cut both wad and hole smooth, the plug, die, and form of
upper member shown in Figure III are used, both the inner and outer conical
surface being caused to impinge a cutting edge, respectively that of the plug and
that of the die. Such arrangement is illustrated in Figure VII.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
1. In a cutter the combination of a cutting edge, a cutting surface terminating in
a cutting edge, and means for causing said surface to impinge upon said first named
edge, substantially as set forth.
2. In a cutter the combination of a cutting edge, a cutting surface terminating in
cutting edge, and means for causing said surface to impinge upon said first named
edge, and said second named edge to pass through the plane of said first named edge,
substantially as set forth.
.3. In a cutter the combination of a cutting edge, a cutting surface inclined to the
plane of said edge and terminating in a second cutting edge and means for causing
said surface to impinge upon said first named edge, substantially as set forth.
4. In a cutter the combination of a circular cutting edge, a conical cutting surface
terminating in a second circular cutting edge coinciding with the circumference of a
circle greater in diameter than that of a circle whose circumference is said first
edge, and means for causing said surface to impinge upon the latter, substantially
as set forth.
