' D I I2 INVENTOR. RICHARD c MALESKI ATI'ORNEYS ARROW TIP I'IAVING REPLACEABLE CUTTING BLADES BACKGROUND OF THE INVENTION The present invention relates to the field of arrowheads or arrow tips and, more particularly, is concerned with broadhead arrow tips in which the fins or cutting blades are replaceable.
Arrow tips of the type to which the present invention is directed are used for hunting game and generally include a plurality of knife-edged blades which increase penetration of the arrow and sever the veins and arteries of an animal to bring about a more rapid and more humane kill. It is important for maximum effect that the knife edges of the cutting blades be extremely sharp so that the arrow will penetrate more easily and insure a severing of veins and arteries. To obtain extreme sharpness, it is known in broadhead arrow tips to employ safety razor blades which are normally provided with a finely honed cutting edge. In some broadhead arrow tips, the blades are glued in place and the entire tip is discarded when the blades become dull. In others, such as disclosed in US. Pat. No..2,880,000, the razor blades are replaceable.
Broadhead arrow tips which are adapted to receive replaceable blades, are advantageous for several reasons. Firstly, the blades can" be replaced whenever they become dull and, therefore, a sharp head is easily maintained. Secondly, the replaceable blades can be removed when the arrow is in storage so that injuries from an otherwise sharp instrument can be avoided. Furthermore, the broadhead arrow tips with the replaceable cutting blades removed can be used for practice shooting without causing extensive damage tothe target or dulling the head. Of course removing the' blades results in a change in the weight of the arrow which can cause slightly different flight characteristics and, therefore, from the bowmans standpoint, it is desirable to have a broadhead arrow tip construction which provides a minimum net change in weight when the cutting blades are removed for practice.
SUMMARY OF THE INVENTION The present invention resides in an arrow tip adapted to receive a plurality of replaceable cutting blades and thus form a broadhead arrow tip. The arrow tip includes an elongated body having coaxial front and rear end portions and a plurality of longitudinal bladereceiving grooves extending along its periphery in circumferentially spaced relationship. The body also has annular groove extending circumaxially about the body and intersecting each of the plurality of blade-receiving grooves. A blade locking member having an annular shape, suchas such as example a snap ring, extends around the body in the annular groove to engage a plurality of the replaceable cutting blades mounted 34 the body. Blade retaining means is connected to the front end portion of the body and cooperates with each of the plurality of blade-receiving grooves to hold the replaceable cutting blades. The cutting blades have attachment apertures which register with the annular groove when mounted in the body portion and tips engaged by the retaining means. The blades are easily removed, replaced, or installed by moving the annular locking member.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a broadhead arrow tip embodying the present invention.
FIG. 2 is a side elevation view of the arrow tip shown in FIG. 1.
FIG. 3 is a longitudinal sectional view of the broadhead arrow tip shown in FIGS. 1 and 2.
FIG. 4 is a transverse sectional view of the broadhead arrow tip as seen along the sectioning line 4-4 of FIG. 3.
DESCRIPTION OF THE PREFERRED EMBODIMENT FIGS. 1-4 show an arrow tip, generally designated 10, which is adapted to receive three replaceable cutting blades 12, 12 to form a broadhead arrow tip. The arrow tip 10 is shown mounted at the forward end of an arrow shaft shown in part for convenience.
The arrow tip 10 comprises an elongated body member 16, a nose peice l8 and a resilient snap ring 20. The body member 16 is cylindrical and the intermediate portion of the body tapers inwardly toward the front portion 24 which is also cylindrical. Th rear portion of the body member 16 defines an axially extending mounting bore 22 which permits the member to be mounted at the forward end of the arrow shaft 14. The cylindrical front portion 24 projects coaxially from the forward end of the member 16 and serves as a support for the nose piece 18.
. The nose piece 18 has the external shape of a pointed projectile and mates at its rear extremity with the tapered external surface of the body member 16. The rear portion of the noxe piece is formed as an internally chamfered skirt section 26 which contains a central, mounting bore 28 reamed to a size permitting the nose piece to be press fitted onto the projecting body portion 24.. e
As seen most clearly in FIGS. 3 and 4, a plurality of longitudinally extending grooves 34 are formed in the external surface of the body member 16 to receive the replaceable blades 12. The grooves 34 are equally circumfe'rentially spaced and extend from the forward end of the body member 16 adjacent the rear end of the nose piece 18 along the tapered external surface of the member toward the rear portion of the member. The grooves have a width which accommodates the cutting blades 12 and support the blades so that they project radially from the member 16. It is contemplated that broadhead arrow tips having two or more replaceable blades can be formed according to the present invention by providing a number of longitudinal grooves corresponding to the number of blades.
At a position between the front and rear end portions of the body member 16, and annular groove 36 extends circumaxially about the body member and intersects each of the longitudinally extending grooves 34. The width of the annular groove 36 is approximately equal to the width of the' snap ring 20 so that the ring 20 can be accommodated within the groove and resiliently engages the body member 16 in the groove to prevent it from shifting in the axial direction along the member.
In accordance with the present invention, the replaceable cutting blades 12 are secured to the body' member 16 by means of the nose piece 18 and the snap ring 20. The blades 12 may be formed from safety razor blades by sectioning the blades along a diagonal so that the cutting edges of the blades, when mounted in the longitudinal grooves 34, are at an angle to the axis of the body member and taper away from the outer surface of the body member at the front end portion. The blades are sectioned so that an attachment aperture 42 registers with the circumaxial slot 36 and permits the snap ring 20 to be laced through each of the blades at the forward end of the aperture to lock the blades to the body member 16. in addition, the pointed forward ends or tips 44 of the blade sections are cut at an angle which permits the tips 44 to project forwardly through the grooves 34 into the rearward facing opening of the skirt section 26 of the nose piece 18 when the attachment apertures 42 are engaged by the snap ring 20. The skirt section 26 therefore, captures each of the blades 12 at their tips 44 and prevents the blades from being dislodged from the grooves 34 at the forward end of the arrow tip 10.
It will also be noted that the longitudinally extending grooves 34 are recessed into the body member 16 at a depth slightly greater than the circumaxial groove 36. As a consequence, the blades 12 rest in the member 16 at a slightly greater depth than the snap ring 20 and the snap ring 20 remains engaged with the annular groove 36. With the snap ring 20 laced through the blades 12 at the forward end of the attachment apertures 42 and also engaged with the annular groove to prevent it from shifting axially along the body mmber 16, the blades 12 are prevented from shifting in the longitudinal direction and, the blade tips 44 can not be disengaged from the skirt section 26 of nose piece 18. The blades 12, therefore, are firmly locked in the body member 16 by the snap ring 20.
Removal of the cutting blades 12 from the arrow tip is readily accomplished by means of the snap ring 20. As seen most clearly in FIG. 4, the snap ring 20 has a discontinuity or missing segment forming a gap 50 which, in the preferred embodiment of the invention, is slightly larger than the width of a cutting blade 12. The ring 20 is rotated in the annular groove 36 of the body member 16 until the gap 50 registers with one of the longitudinal grooves 34. The cutting blade 12 in that one groove is then shafted slightly rearwardly to disengage the tip 44 and is lifted out of the groove 34 and away from the body member 16. The process is repeated for each of the other blades until all of the blades are removed. Since the snap ring 20 and nose piece 18 remain attached to the body member 16, the net change in weight of the arrow tip 10 associated with the removal of all blades 12 is limited to the combined weight of the blades themselves and the principal weight of the broadhead tip found in the body member 16, the nose piece 18 and the snap ring 20 remains attached to the arrow shaft. With the blades removed, the arrow tip maintains its streamlined configuration and the nose piece 18 provides a point which is adequate for penetrating practice targets.
installation of the cutting blades 12 is also a simple operation. With the gap 50 of the snap ring 20 registering with a groove 34, a blade 12 is installed in the groove 34 with the blade tip projecting into the skirt section 26 of nose piece 18. The snap ring 20 is then rotated through the attachment aperture 42 until the gap 50 registers with the next groove. As each blade is installed, it is individually locked in place and remains so positioned without any cooperation from blades in the other longitudinal grooves 34. When all of the blades 12 are installed, the snap ring 20 is rotated to place the gap 50 between two of the grooves 34 as seen in FIG. 4 and the assembled broadhead is ready for use.
It will thus be seen that the arrow tip 10 is readily adapted to the installation and removal of replaceable cutting blades and that the blades once installed are securely anchored to the arrow tip to form a well balanced, light weight construction.
