Abstract
Abstract An improved drumstick and end tip therefor which is affixed to the reduced end of the stick. The reduced end is characterized by an axially elongate bore which is adapted to receive an extending arm of the tip. The tip is of substantially frusto-oval configuration and is characterized by an axial bore of diameter sufficient to fit over the reduced end of the stick. At the base of the bore internally of the tip is the longitudinally extending arm of a length slightly less than the bore in the end of the stick. Affixation of the tip to the stick requires insertion of the stick into the tip bore and concomitant insertion of the arm into the stick bore thereby markedly enhancing frictional engagement between the tip and stick.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
243 words
In a drumstick for transmitting impact forces from an end thereof to a receiving surface, the force transmitting end having attached thereto a tip configured as a surface of revolution the improvement residing in the means of attachment and comprising: a recess formed in the force transmitting end of the stick, said tip being characterized by a bore extending thereinto from a surface thereof, the stick fittingly engaging the walls of the bore when the force transmitting end is inserted therein and the base of the bore being characterized by locating means extending into the bore itself and also into abutting contact with the recess in the force transmitting end of the stick so that working of the tip is effectively precluded because of the relatively fixed relationship of the end of the stick to the base of the bore, said locating means is further characterized as an extending arm of elongate cantilever configuration, and the recess in the stick end being further characterized as an elongate axial bore so that insertion of the former into the latter enhances the frictional engagement of the two, and the surface of the impact receiving end of the stick is roughened so as to enhance frictional engagement with the tip, and the walls of the recess in the end of the stick diverge slightly from the top to the bottom thereof and the walls of said extending arm are configured to fittingly engage the recess walls.
Claim 2
Dependent Claim

In a drumstick for transmitting impact forces from an end thereof to a receiving surface, the force transmitting end having attached thereto a tip configured as a surface of revolution the improvement residing in the means of attachment and comprising: a recess formed in the force transmitting end of the stick, said tip being characterized by a bore extending thereinto from a surface thereof, the stick fittingly engaging the walls of the bore when the force transmitting end is inserted therein and the base of the bore being characterized by locating means extending into the bore itself and also into abutting contact with the recess in the force transmitting end of the stick so that working of the tip is effectively precluded because of the relatively fixed relationship of the end of the stick to the base of the bore, said locating means is further characterized as an extending arm of elongate cantilever configuration, and the recess in the stick end being further characterized as an elongate axial bore so that insertion of the former into the latter enhances the frictional engagement of the two, and the surface of the impact receiving end of the stick is roughened so as to enhance frictional engagement with the tip, and the walls of the recess in the end of the stick diverge slightly from the top to the bottom thereof and the walls of said extending arm are configured to fittingly engage the recess walls.
Claim 3
Dependent Claim
34 words
The drumstick of claim 1 wherein the force transmitting end of said stick is characterized by a protuberance means on the surface thereof for further enhancing the gripping action between the stick and tip.
Claim 4
Dependent Claim
37 words
The drumstick of claim 2 wherein the bore of the tip is characterized by a cooperating depression means therein, said protuberance means engaging the depression means so as to more reliably affix the tip to the stick.
Claim 5
Dependent Claim
31 words
The drumstick of claim 1 wherein the bore of the tip is characterized by a protuberance means which engages the surface of the stick for enhancing gripping connection of the two.
Claim 6
Dependent Claim
29 words
The drumstick of claim 4 wherein the surface of the stick is characterized by a cooperating depression means for receiving the protuberance means in the bore of the tip.
Claim 7
Dependent Claim
257 words
In a drumstick for transmitting impact forces from an end thereof to a receiving surface, the force transmitting end having attached thereto a tip configured as a surface of revolution, the improvement residing in the means of attachment and comprising: a recess formed in the force transmitting end of the stick, said tip being characterized by a bore extending thereinto from a surface thereof the stick fittingly engaging the walls of the bore when the force transmitting end is inserted therein and the base of the bore being characterized by a locating means extending into the bore itself and also into abutting contact with the recess in the force transmitting end of the stick so that working of the tip is effectively precluded because of the relatively fixed relationship of the end of the stick to the base of the bore, said locating means further characterized as an extending arm of elongate cantilever configuration, and the recess in the stick end being further characterized as an elongate axial bore so that insertion of the former into the latter enhances the frictional engagement of the two, the walls of the recess in the end of the stick diverging slightly from the top to the bottom thereof and the walls of said extending arm being configured to fittingly engage the recess walls so as to thereby enhance the frictional engagement between the stick and the tip and to preclude separation of the tip and stick as a consequence of forces perpendicularly directed to the longitudinal axis of the stick.
Claim 8
Dependent Claim
257 words
In a drumstick for transmitting impact forces from an end thereof to a receiving surface, the force transmitting end having attached thereto a tip configured as a surface of revolution, the improvement residing in the means of attachment and comprising: a recess formed in the force transmitting end of the stick, said tip being characterized by a bore extending thereinto from a surface thereof the stick fittingly engaging the walls of the bore when the force transmitting end is inserted therein and the base of the bore being characterized by a locating means extending into the bore itself and also into abutting contact with the recess in the force transmitting end of the stick so that working of the tip is effectively precluded because of the relatively fixed relationship of the end of the stick to the base of the bore, said locating means further characterized as an extending arm of elongate cantilever configuration, and the recess in the stick end being further characterized as an elongate axial bore so that insertion of the former into the latter enhances the frictional engagement of the two, the walls of the recess in the end of the stick diverging slightly from the top to the bottom thereof and the walls of said extending arm being configured to fittingly engage the recess walls so as to thereby enhance the frictional engagement between the stick and the tip and to preclude separation of the tip and stick as a consequence of forces perpendicularly directed to the longitudinal axis of the stick.
