SERPENTINE ARROWHEAD
Abstract
An arrowhead having two cutting edge portions extending
rearwardly from their point of attachment to a frontal blade
portion, and spiraling about the axis of an arrowhead ferrule. Each
cutting edge portion encompasses 180.degree. of the ferrule so that
acting together they cut a plug from the flesh of an animal target.
At their rear points of attachment the cutting edge portions are
fastened by a mechanical interlock to flanges which extend radially
outwardly from the ferrule. The cutting edge portions may be made
replaceable.

Claims
The foregoing is considered as illustrative only of the principles
of the invention. Further, since numerous modifications and changes
will readily occur to those skilled in the art, it is not desired
to limit the invention to the exact construction and operation
shown and described, and accordingly all suitable modifications and
equivalents may be resorted to, falling within the scope of the
invention as claimed.
1. An arrowhead including an elongated body adapted to be
lengthwise mounted on the front end of an arrow shaft with the
center axis of said body coinciding with the centerline of said
shaft, said body including a blade structure having a forward
platelike portion generally triangular in plan shape, the forward
portion being disposed generally in a diametric plane of said shaft
with one of its apices disposed forwardmost, the side marginal
edges of said forward portion diverging rearwardly from said one
apex and terminating rearwardly in elongated blade portions
including forward ends forming rearward continuations of said side
marginal edges, said blade portions, rearward of said forward
portion, being spiraled about said body in the same direction with
the rear ends of said blade portions curving inwardly toward and
secured to said body and intersecting said plane on the sides of
said axis remote from the corresponding forward ends of the blade
portions, said body including rearwardly disposed longitudinally
extending and generally radially outwardly projecting flange
portions disposed in said plane, the rear ends of said blade
portions being secured to said flanges for support of said rear
ends from said body.
2. The combination of claim 1 wherein said rear ends extend through
the medial planes of said flanges.
Description
The arrowhead of the instant invention has a pair of opposite side
cutting edges and the cutting edges are acutely inclined relative
to the longitudinal axis of the head throughout substantially their
entire length. In this manner, the cutting edges of the arrow will
readily slice any flesh into which the arrow is forced.
Many different types of hunting arrows and the like are provided
with cutting edges which extend longitudinally of the associated
arrow and are inclined only slightly relative to the longitudinal
axis of the arrow, but most of these arrowheads include means only
for slitting the flesh into which the arrowhead is shot adjacent
the area of the flesh pierced by the arrow shaft and each slit is
formed in a manner such that it may readily close in a manner such
that free bleeding of big game struck with such an arrow can be
substantially completely eliminated.
Of course, when an archer makes a vital hit on a big game animal,
he hopes for a good blood trail for tracking. Too often this trail
is meager or absent, leaving the bow hunter no recourse except to
abandon his search. Of course, although the hunter may not be able
to trail such big game, substantially all broad headed arrowheads
will kill and the wounded game will eventually die with no benefit
being gained. Accordingly, it is the main object of this invention
to provide a broad-headed arrowhead which will be operable to
completely cut away portions of flesh immediately adjacent the
portion of flesh pierced by the arrow shaft so as to induce free
bleeding which cannot be checked to any great extent by the flesh
closing about the arrow shaft.
While a sharpened concentric ring carried by and spaced outwardly
from all sides of an arrowhead or at least portions of such a ring
might be operable to cut away portions of flesh immediately
adjacent the area of flesh pierced by an associated arrow shaft,
such rings or ring portions do not readily slice through flesh and
are operable to cut the flesh in the desired manner only when there
is sufficient momentum of the associated arrow to drive the ring or
ring portions through the flesh. Accordingly, it is another
important object of this invention, in accordance with the
immediately preceding object, to provide an arrowhead including
sharpened edge portions for cutting away portions of flesh but
which are inclined, throughout substantially their entire length,
at least 30.degree. relative to a plane disposed normal to the
associated arrow shaft.
Yet another object of this invention is to provide an arrowhead in
accordance with the preceding objects and including readily
removable and replaceable cutting edges.
A final object of this invention to be specifically enumerated
herein is to provide an arrowhead in accordance with the preceding
objects which conform to conventional forms of manufacture, be of
simple construction and easy to use so as to provide a device that
will be economically feasible, long lasting and relatively
trouble-free in operation.
These together with other objects and advantages which will become
subsequently apparent reside in the details of construction and
operation as more fully hereinafter described and claimed,
reference being had to the accompanying drawings forming a part
hereof, wherein like numerals refer to like parts throughout, and
in which:

constructed in accordance with the present invention;
FIG. 2 is an exploded perspective view of the two opposite side
components which are utilized to form the arrowhead;
FIG. 3 is a side elevational view of the arrowhead mounted on the
forward end of an arrow shaft;
FIG. 4 is a front elevational view of the arrowhead of FIG. 3;
FIG. 5 is a top plan view of the arrowhead of FIGS. 3 and 4;
FIG. 6 is a side elevational view of a second form of arrowhead
constructed in accordance with the present invention and including
removable cutting blade portions;
FIG. 7 is a fragmentary enlarged sectional view taken substantially
upon the plane indicated by the section line 7--7 of FIG. 6;
FIG. 8 is a fragmentary enlarged sectional view taken substantially
upon the plane indicated by the section line 8--8 of FIG. 6;
and
FIG. 9 is a fragmentary plan view of a flexible panel member
constructed of leather or similar material and through which an
arrow equipped with the arrowhead of the instant invention has been
shot, the flexible panel clearly including an opening cut by the
arrow having two enlarged portions disposed on opposite sides of
the portion of the panel pierced by the arrow shaft.
Referring now more specifically to the drawings the numeral 6
generally designates an arrow including a shaft 8 and a first form
of arrowhead generally referred to by the reference numeral 10. The
arrowhead 10 includes an elongated center body portion referred to
in general by the reference numeral 12 and is formed from two
identical half sections 14 and 16. Each half section 14 includes a
half conical portion 18 and a pair of oppositely directed opposite
side coplanar flange portions 20 and 22 provided with short
generally rectangular slots 24 and 26. Further, each of the half
sections 16 includes a generally triangular point or forward
portion 30.
The half sections 14 and 16 are secured together with the flange
portions 20 and 22 and the point portions 30 disposed in surface to
surface contacting relation in any convenient manner such as by
soldering or brazing. The half conical portions 18 then define a
full conical portion or recess into whose major diameter end
portion the associated arrow shaft 8 may be wedged.
Each of the half sections 14 and 16 includes an elongated thin
striplike blade member 32 which projects outwardly and rearwardly
from the corresponding point portion 30 and defines a rearward
extension of the corresponding side edge thereof. The free end of
each blade member 32 is notched as at 34 and the forwardly facing
edge 36 thereof is sharpened. The blade members 32 are twisted
about their longitudinal axes approximately 270.degree. while the
free ends of the blade members are urged inwardly toward the half
conical portions 18 for anchoring engagement of the notches 34
within the corresponding pairs of registered slots 24 and 26. Thus,
the free ends of the blade members 32 are readily releasably
anchored to the rear end portions of the flange portions 20 and 22.
Of course, if it is desired to sharpen the blade members 32 along
the sharpened edges 36 thereof, it is only necessary to disengage
the notched ends of the blade members 32 from the flange portions
20 and 22 and to renew the sharpened edge 36. However, it is
possible to sharpen the sharpened edges 36 while the blade members
32 are anchored to the flange portions 20 and 22 and therefore the
notched ends to the blade members 32 may be soldered or brazed to
the flange portions 20 and 22 after having their notched ends
engaged in the corresponding pair of registered slots 24 and
26.
From FIGS. 3 and 5 of the drawings it may be seen that the
sharpened edge portions 36 are inclined at least 30.degree.
relative to a plane disposed normal to the longitudinal centerline
of the arrowhead 10 and FIG. 4 of the drawings it may be seen that
the blade members 32 enclose enlarged areas on opposite sides of
the body portion 12 which will be cut away from the flesh into
which the arrowhead 10 is forced.
With attention now invited more specifically to FIGS. 6-8 of the
drawings, there will be seen a modified form of arrowhead referred
to in general by the reference numeral 110 and which is
substantially identical to the arrowhead 10 except that the blade
members 132 thereof are fully removable from the arrowhead 110,
portions of the arrowhead 110 corresponding to various numbered
portions of the arrowhead 10 having been given similar reference
numerals in the 100 series.
The opposite sides of the forward triangular platelike portions 130
of the arrowhead 110 are recessed as at 131 to receive the forward
ends of the blade members 132 and are provided with notched anchor
pins 133 to which the forward ends of the blade members 132 may be
removably anchored by reception of the notched anchor pins 133
through the apertures 135 formed in the blade members 132. Of
course, the rear ends of the blade members 132 are notched as at
134 and may therefore be secured to the rear end portion of the
body 112 in the same manner in which the rear ends of the blade
members 32 are secured to the body member 12.
Of course, the operation of the arrowhead 110 is substantially
identical to the operation of the arrowhead 10 and it may be seen
from FIG. 9 of the drawings that a pair of diametrically opposite
enlarged cutout areas 137 and 139 are formed in the panel 141 upon
the arrowhead 110 being shot through the panel 141.
Of course, as can be viewed from FIG. 4, the curved blade members
32 and 132 do not present any frontal area greater than their
sharpened edge portions toward the front of the arrowheads 10 and
110 and therefore the provision of the curved blade members 32 and
132 does not appreciably increase air resistance to the arrowheads
10 and 110 passing through the air. Further, any tendency of the
associated arrow to rotate about its longitudinal axis will assist
in the blade members 32 cutting plugs of flesh out of the animal
adjacent the portion of the flesh pierced by the associated arrow
shaft by the drilling action of the rotating arrow, its forward
movement, and the configuration of the blade members 32 and
132.
