HANDCHIME INSTRUMENT

Abstract: A hand held musical instrument is capable of emitting sound through the combination of three elements: a hollow tube (1), a striking member, and a hinge (3) to secure the striking member to the tube. The hollow tube is constructed of an ergonomic shape that allows easy and fatigue-free grasping. For low notes, the slots on the resonating end of the hollow tube are multiple-sized to eliminate buzzing. The clapper is attached to the hollow tube through a combination of a stainless steel axle (10), polymer bearings (11a, 11b) and adjustable tensioning screws (12a, 12b). This combination improves the durability of the instrument yet still allows the musician to adjust the strike fell. The invention also provides improvements in the clapper heads for both low note and middle and high note handchimes. For low notes, the clapper head is constructed of multiple layers that optimize sound quality. For middle or high notes, the rubber clapper head provides multiple settings which allows the musician to easily and precisely adjust the timbre setting.

Description: HANDCHIME INSTRUMENT FIELD OF THE INVENTION This invention relates to a hand held, percussion musical instrument that emits sound through striking a clapper onto the slotted end of a hollow aluminum tube More particularly, the present invention relates to a handchime BACKGROUND OF THE INVENTION The prior art discloses many inventions that cause sound to be emitted by striking a hammer, knocker, clapper, or similar means against a tube, triangle or other object. These devices can be differentiated by, but are not limited to, the sounds that they emit, the striking means itself, the object being struck, the method of attaching the striking means to the device, or the method of playing the device Handchimes vibrate in an infinite number of ways, or modes, when struck by a clapper Only a few of these modes cause the surrounding air to vibrate at a frequency strong enough to be audible to the human ear The lowest frequency vibration, or the lowest pitch, is called the fundamental. The clapper of a handchime drives the generated frequencies Like handbells, handchimes are typically sold in octave or multi-octave sets A handchime, like a handbell, is individually tuned to emit a particular note Handbells are tuned by removing metal from their inner diameter Handchimes are tuned by adjusting the length and/or width of their slots. The handchimes within an octave set vary in cross sectional area depending upon the note the chime will emit Larger cross-sectional areas are used for lower octave or lower note handchimes For example, a three octave or 37 note set of handchimes may utilize three different cross-sectional areas Therefore, in a typical three octave set, 13 notes, which include C4, C#4/D b 4, D4, D#4/E b 4, E4, F4, F#4/G b 4, G4, G#4/A b 4, A4, A#4/B b 4, B4, and C5, are considered lower note or larger cross-section handchimes The balance of the typical three octave set or the remaining 24 notes, C#5/D b 5, D5, D#5/E b 5, E5, F5, F#5/G b 5, G5, G#5/A 5, A5, A#5/B b 5, B5, C6, C#6/D 6, D6, D#ό/E b6, E6, F6, F#6/G b 6, G6, G#6/A b 6, A6, A#6/B b6, B6 and C7 are considered smaller cross-section handchimes and emit middle or higher pitched notes The cross sectional areas of the handchimes will change with respect to each other as a three octave set is expanded to 4, 5 or 6 octaves Few of the devices disclosed in the prior art allow control over the musical tones that are produced Ease of playing or the economical manufacture of the device is at the sacrifice of the overall musical quality of the instrument Lastly, in the devices disclosed that contain moving parts for the striking means, the moving parts are seldom durable over the life of the product One objective of the present invention is to produce a handchime of an ergonomic shape that allows ease of holding and long-term fatigue-free use It is an additional objective of the invention to fabricate the support shaft for the striking member of a sufficient weight such that it requires no additional weight to obtain the proper impact force It is a further objective of the invention to attach the striking member to the main body of the instrument in a manner that allows the musician to set the strike "feel" to their preference yet still allow long life, durability, and ease of operation For middle and higher pitched notes or smaller cross-section handchimes, it is another objective of the invention to design the cross-section of the support shaft to correspond to the various timbre settings of the clapper head for flexible voicing yet still allow for quick and easy adjustments without the benefit of elaborate tools For lower note or larger diameter handchimes, it is an objective of the invention to allow proper sound generation without any discordant overtones such as "slapping" or "pinging " Lastly, for lower note or larger cross-section handchimes, it is a further objective of the invention to eliminate the discordant overtone known as "buzzing" by controlling the width and length of the slot SUMMARY OF THE INVENTION The aforementioned objectives are met by the present invention Handchimes in accordance with the presently preferred embodiments of the invention are divided into three main elements the main body or tube, the striking member or clapper, and the method of joining the clapper to the main body The present invention provides novel features to all three elements The shape of the mam tube offers many advantages Preferably, the tube is designed to be constructed from octagonal cross-section aluminum tubmg This shape is ideal for use by children or the elderly The octagonal cross-section is therefore optimal ergonomically Lastly, to further aid in the comfort of holding and playing, the octagonal tube has a textured powder paint coat for sure gripping and durability The main tube is partitioned into two compartments by an internal plug The plug is preferably constructed of a solid surface and a "waffled" surface on the opposite side The plug has a waffled or voided side to allow deformation or folding of the plug during installation A preferred embodiment of this invention has the plug comprised of remanufactured "NYLON" 6/6 which holds the plug firmly in place despite use, storage, handling, and variations in temperature The position of the plug within the tube is chosen in accordance with the particular note that the chime emits One end of the tube is used to hold the instrument For lower notes, singular-sized slot configurations may encourage the production of a "buzzing" sound due to extraneous resonant frequencies being generated by the combination of the width and length of the slot The present invention, by contrast, eliminates or discourages "buzzing" by adopting a multi-sized slot configuration The multi- sized slot "tunes out" the extraneous frequencies and eliminates the "buzzing " The present invention uses a hinge assembly that incorporates a combination of a stainless steel axle set in a pair of polymer (1 e , "NYLINER") bearings and adjustable via concealed, tensioning screws The axle and polymer bearings seldom need lubrication This combination provides accurate, secure alignment of the shaft assembly and eliminates any looseness or "play" in the instrument The threaded holes for the tensionmg screws allow tight-fitting thread engagement so that the use of a thread bonding adhesive, such as "LOC- TITE" adhesive to impede the movement of the threads during normal use, is eliminated In addition, the tensionmg screws allow the musician to ad)ust the tensionmg on the axle and bearings to set the strike "feel" to his or her preference The musician can simply adjust the tensionmg screws to decrease or increase the tension Less wear is inflicted on the bearings with no loss of durability or longevity of the instrument Thus the combination of these features minimizes maintenance and wear of the instrument An additional advantage of the present invention is seen in the shaft that supports the clapper head The clapper support shaft is molded into its yoke rather than pinned in place The shaft is of sufficient weight to eliminate the need for additional weight at the end of the clapper head to obtain the proper impact force The shaft length for each note is then individually sized to strike the tube at the optimum strike point For middle or high notes or smaller cross-section chimes, the hexagonal cross- section segment of the clapper support shaft also allows for flexible voicing For these notes, the clapper head has six different timbre settings The simple assembly of the clapper head to the support shaft allows the musician to reposition the clapper head to a different timbre setting Because the timbre settings correspond to each side of the hexagonal cross-section of the support shaft, the musician can easily and precisely set the clapper head to a particular timbre setting Further, the female form of the inner dimension of the clapper head, which is hexagonal shaped to align with the support shaft, allows precision indexing of the timbre setting by eliminating torsional strain or twisting of the clapper head around the support shaft The present invention, in its preferred embodiment, incorporates a positioning groove on the clapper support shaft to hold the eccentric rubber bumper relatively fixed in place along the shaft's longitudinal axis The eccentric rubber bumper is circular in shape with an interior hole that is offset from center The groove is located on the support shaft at the opposite end of the clapper head The positioning groove holds the rubber bumper securely in place longitudinally The convenient location of the eccentric rubber bumper, at the base of the clapper shaft, allows the musician to achieve damping by simply rotating the eccentric rubber bumper within the positioning groove rather than sliding the bumper down the clapper shaft Rotating the eccentric bumper impedes the swing arc of the clapper Lastly, for lower notes, the present invention utilizes amulti-layer construction for the clapper head which, in its preferred embodiment, consists of an insert, encapsulated by a synthetic thermoplastic rubber such as "SANTOPRENE" or "DYNAFLEX" and then covered by an exterior layer of flocked "NYLON". The multi-layer construction of the clapper head optimizes the proper sound generation. Other materials were considered and proved effective for the multi-layer construction, such as thermoset rubber in place of the thermoplastic rubber, but the present embodiment was preferred from a cost and performance viewpoint. The clapper head is donut-shaped and contains a core that is a molded "NYLON" insert that does not extend through the clapper head. The inner diameter of the "NYLON" insert, which faces the hinge assembly, has a circular inner diameter and is in the female form. On the opposite end of the clapper head, synthetic thermoplastic rubber is molded around and on top of the "NYLON" insert. A hole is borne through the thermoplastic rubber to allow the clapper head to be seated on the end of the clapper support shaft with the threaded end of the clapper shaft exposed. The clapper head is designed so that the thermoplastic rubber lines the hole borne through the "NYLON" insert. Thus, the clapper head support shaft is not in direct contact with the "NYLON" insert for its entire length. Optimal sound generation is thereby promoted by eliminating any "slapping" sound which results from the support shaft hitting the "NYLON" insert when the clapper strikes the chime tube. Further, the exterior layer of "NYLON" flocking is advantageous over felt clapper heads because it eliminates nuisance "pinging" sounds due to its softer contact surface. Other features and advantages of the present invention are disclosed below.

PREFERRED EMBODIMENTS Figure 1 is an isometric view of the larger diameter handchime The handchime is constructed from an octagonal-sided, aluminum tube 1 Figure 1 also shows the clapper head support shaft 8 and hinge 3 Figure 2 is a cross-sectional view of the larger diameter handchime Tube 1 is partitioned by plug 2 (a cross-section of the "waffled" side of plug 2 is illustrated in Figure 8) into two compartments a hollow open end 1 a and a multi-slotted end lb The position of plug 2 within tube 1 will vary depending upon the particular note and octave that the chime is intended to emit Figure 3 is an enlarged cross-sectional view of the hinge assembly shown in Figure 2 The hinge assembly is similar in both the large and small diameter handchimes Hinge 3, which is made of a polymer such as "ACETAL' , is attached to tube 1 through two fasteners, 4a and 4b The preferred embodiment discloses the hinge elevated from tube 1, however, the hinge can also be flush mounted Hinge 3 has a recessed area on its top surface to place a label 5 and felt pad back stop 6 Hmge 3 is also shaped to allow for a thumb rest Back stop 6 is affixed to hinge 3 to prevent the contact of yoke 7 to hinge 3 and also to limit its swing range Clapper support shaft 8 is molded into yoke 7 Clapper support shaft 8 can be viewed as being comprised of three different segments 8a 8b, and 8c Segment 8a has a circular cross section and is of varying cross section that serves as a positioning groove for eccentric rubber bumper 9 Eccentric rubber bumper 9, which has a circular inner diameter offset from center as illustrated in Figure 9, is placed at segment 8a of support shaft 8 Bumper 9 acts as a damper and allows quick control over volume and response Segment 8b has a hexagonal cross section and constitutes the majority of the length of clapper support shaft 8 Segment 8c has a circular cross section and a threaded end at the tip of clapper support shaft 8 where the clapper head is attached Figure 4 is a cross-sectional view which shows the relationship of yoke 7 to hinge 3 taken at sectional line 4-4 of Figure 3 Yoke 7 can swing freely due to axle 10 Axle 10 joins hinge 3 and yoke 7 via a pair of polymer (such as "NYLINER") bearings 11a and l ib Figure 5 is a cross-sectional top view taken at sectional line 5-5 of Figure 4 Figure 5 shows tensionmg screws 12a and 12b which are perpendicular to axle 10 and can be used by the musician to adjust the strike feel to his or her preference Figure 6 shows a detailed, cross-sectional view of the clapper head assembly for larger handchimes taken at sectional line 6-6 of Figure 2 Clapper head 13 is comprised of a"NYLON" insert core 14, an encapsulating layer of synthetic thermoplastic rubber (such as "SANTOPRENE" or "DYNAFLEX") 15, and an outside covering of flocked nylon 16 The thermoplastic layer is also molded in the inner diameter of insert core 14 so that the 8c segment of clapper shaft 8 has direct contact with the thermoplastic rubber layer 15 rather than the "NYLON" insert 14 Contact with layer 15 dampens any "slapping" that may occur Insert 14 does not extend through clapper head 13 and has a larger inner diameter 14a at its base than at its top 14b, as illustrated in Figure 7 The side of the clapper head 13, facing the hinge assembly, appears in the female form This allows clapper head 13 to slide over the end of segment 8b of clapper support shaft 8 The end of segment 8b coincides to the depth of the inner diameter 14a of "NYLON" insert 14 Inner diameter 14b of clapper head 3 is slid over segment 8c or the threaded end of clapper support shaft 8 Segment 8c extends out over the end of clapper head 13 After clapper head 13 is placed on the end of the clapper head support shaft 8, positioning washer 17 is then slid over this threaded end Acorn nut 18 secures washer 17 and clapper head 13 in place An alternative embodiment of the described handchime is depicted in Figure 10 Figure 10 shows an isometric view of the smaller cross section or middle or higher note handchime As Figure 10 illustrates, the smaller cross-section handchime is composed of a hollow, octagonal cross-sectional tube 18 that is partitioned by plug 2 into two compartments a hollow open end 18a and a single-slotted end 18b The hinge assembly and clapper support shaft assemblies are essentially the same for both the larger and smaller diameter embodiments Figure 11 illustrates a cross-sectional view of the thermal plastic rubber clapper head 19 attachment to segment 8c of clapper support shaft 8 taken at sectional line 11-11 of Figure 10 Typical duoremeter measurements, or rubber hardness, for clapper head 19 in a 3 octave set are as follows 40 shore D, 68 shore A or 80 shore A Duoremeter measurements vary depending upon the desired note and octave that the handchime corresponds to The side of clapper head 19, which faces the hinge assembly, is in the female form Figure 12 shows a cross-sectional view of clapper head 19 taken at sectional line 12-12 of Figure 11 Clapper head 19 is donut shaped and has two inner dimensions 19a and 19b Inner dimension 19a, it made in a female form, is hexagonal shaped, and extends to a depth which is approximately half the thickness of clapper head 19 Because it is in the female form, it allows clapper head 19 to slide over segment 8b of clapper support shaft 8 Inner diameter 19b, has a circular cross section and smaller inner dimension than 19a, which allows clapper head 19 to slide over segment 8c of clapper support shaft 8 The threaded end of segment 8c extends over the width of clapper head 19 After clapper head 19 is placed on the end of clapper support shaft 8, positioning washer 17 is set in place Acorn nut 18 secures washer 17 and clapper head 19 in place Figure 12 also depicts the multiple strike point positions 20a through 20f of clapper head 19 Positions 20a, 20b, and 20f are circular-shaped apertures of varying radii Position 20c is blank Lastly, positions 20d and 20e are slotted apertures with radial edges but vary in length The musician can change the strike position of clapper head 19 by removing the acorn nut 18 and washer 17 and repositioning clapper head 19 on clapper support shaft 8 The instrument is played by holding tube 1 or 18 upright at hollow, open end la or 18a (depending upon the diameter ofthe tube or the note being played) The musician swings tube 1 or tube 18 down using a short "snap" of the wrist which causes the clapper assembly to swing downwards in a limited arc until clapper head 13 or 19 strikes the slotted end (either lb or 18b) emitting the particular note Conclusion In view of the foregoing, it is apparent that the present invention provides novel features that distinguish the invention over the prior art These novel features are summarized below First, in the preferred embodiments, the shape of the main tube offers advantages over the prior art Preferably, the tube is designed to be constructed from octagonal cross-section aluminum tubing Other handchimes disclosed in the prior art are constructed of standard square cross-section tubing, similar to that used for table and chair legs The instant invention is preferable to the square cross-section handchimes because the octagonal cross-section is more comfortable to hold and play Still other handchimes in the prior art are of square cross-section but have rounded edges or have rounded or "bowed" sides The octagonal cross-section is optimal ergonomically In addition, as described above, the hollow aluminum tube is preferably partitioned by an internal plug The position of the plug within the tube is selected in accordance with the particular note that the chime is to emit One compartment or end ofthe tube is used to hold the instrument The plug is waffled on the side that faces the holding end The opposite end, or resonating end, is slotted The prior art discloses examples of handchimes (such as U S Pat No 4,599,932) or musical bells (such as U S Pat No 991,704) that also include a slotted, resonating end The slots in both of these patents are of one size For lower notes, single- sized slot configurations may encourage the production of a "buzzing" sound due to the generation of extraneous resonant frequencies being generated by the combination of the width and length of the slot The present invention, by contrast, eliminates or discourages "buzzing" by adopting a multi-sized slot configuration The multi-sized slot "tunes out" the extraneous frequencies and eliminates the "buzzing " The prior art also discloses numerous means to attach the clapper to the mam body of the instrument Some patents disclose the use of an elastomenc hinge while others disclose the use of a rivet Although the prior art discloses some examples that use metal plates and pins to attach the striking member to the main body of instrument, few of these provide the advantages that the present invention offers The present invention incorporates a hinge assembly that features a combination of a stainless steel axle set in a pair of polymer bearings (l e , "NYLINER") and made adjustable via concealed tensionmg screws The axle and polymer bearings seldom need lubrication This combination provides accurate, secure alignment of the shaft assembly and eliminates any looseness or "play" in the instrument The threaded holes for the tensionmg screws allow tight-fitting thread engagement so that the use of a thread bonding adhesive, such as "LOC-TITE" adhesive to impede the movement of the threads during normal use, is eliminated In addition, the tensionmg screws allow the musician to adjust the tensionmg on the axle and bearings to set the strike "feel" to his or her preference The musician can simply ad]ust the tensionmg screws to decrease or increase the tension Less wear is inflicted on the bearings with no loss of durability or longevity ofthe instrument Thus, the combination of these features minimizes maintenance and wear ofthe instrument An additional advantage of the present invention is seen in the shaft that supports the clapper head The clapper support shaft is molded into its yoke rather than pinned in place The shaft is of sufficient weight to eliminate the need for additional weight at the end of the clapper head to obtain the proper impact force The shaft length for each note is then individually sized to strike the tube at the optimum strike point For middle or high notes or smaller diameter chimes, the hexagonal cross- section segment ofthe clapper support shaft also allows for flexible voicing For these notes, the clapper head has six different timbre settings The simple assembly of the clapper head to the support shaft allows the musician to reposition the clapper head to a different timbre setting The preferred embodiment ofthe invention discloses five different shaped openings of varying radii plus one blank area to allow the musician to adiust the timbre Because the timbre settings correspond to each side of the hexagonal cross-section of the support shaft, the musician can easily and precisely set the clapper head to a particular timbre setting The prior art discloses many instruments that provide a flexible or sliding rubber bumper as a damping means The present invention, in its preferred embodiments, differs from the prior art by incorporating a positioning groove on the clapper support shaft to hold the eccentric rubber bumper relatively fixed in place along the shaft's longitudinal axis The groove is located on the support shaft at the opposite end of the clapper head The positioning groove holds the rubber bumper securely in place longitudinally The convenient location ofthe eccentric rubber bumper, at the base ofthe clapper shaft, allows the musician to achieve damping by simply rotating the eccentric rubber bumper within the positioning groove rather than sliding the bumper down the clapper shaft Rotating the eccentric bumper impedes the swing arc ofthe clapper Another advantageous aspect of the preferred embodiments lies in the utilization of a multi-layer construction for the clapper head that includes an insert, encapsulated by a thermoplastic rubber and then covered by an exterior layer of flocked "NYLON " This multi-layer construction of the clapper head optimizes the proper sound generation The clapper head is donut-shaped and contains a core that is a molded "NYLON" insert that does not extend through the clapper head The inner diameter ofthe "NYLON" insert is larger at the base than at the top The thermoplastic rubber is molded around and on top ofthe "NYLON" insert on the end that faces an acorn fastener A hole is borne through the thermoplastic rubber to allow the clapper head to be seated on the end of the clapper support shaft with the threaded end of the clapper shaft exposed The clapper head is designed to allow the thermoplastic rubber to line the hole borne through the "NYLON" insert Thus, the clapper head support shaft is not in direct contact with the "NYLON" insert for its entire length Optimal sound generation is thereby promoted by eliminating any "slapping" sound which results from the support shaft hitting the "NYLON" insert when the clapper strikes the chime tube Further, the exterior layer of "NYLON" flocking is advantageous over felt clapper heads disclosed in the prior art because it eliminates nuisance "pinging" sounds due to its softer contact surface The presently preferred embodiment for a typical large cross section handchime, such as note D4, consists of an octagonal cross-section aluminum tube, which has a cross-section that is 1-1/2 inches wide by 1-1/2 inches high and a length of 18 inches The plug is inserted 5/8 inches in from the holding end of the tube The resonating end has a multi-sized slot that can be viewed as having two segments The first segment, which opens to the resonating end, has a length of 4-5/16 inches and a width of 3/8 inch The other segment, which is closest to the hinge assembly, has a length of 1 -7/16 inches and a width of 11/16 inches The second slot segment also has radial-shaped edges The length of the clapper support shaft, which extends from the eccentric bumper to the clapper head, is 5-1/8 inches The multi-layer clapper head has a diameter of 1-3/8 inches and a height of 7/8 inches The eccentric rubber bumper, which is located at the base of the support shaft, has a diameter of 11/16 inches and a height of 1/4 inch The presently preferred embodiment ofthe small diameter handchime for note F#5/G 5 consists of an octagonal aluminum tube, which has a cross-section that is 1-1/4 inches wide by 1-1/4 inches high and a length of 10-3/4 inches The plug is inserted 3 inches in from the holding end ofthe tube The resonating end has a single-sized slot, which has a length of 3-9/16 inches and a width of V-≥ inch The slot segment has radial-shaped edges The length of the clapper support shaft, which extends from the eccentric bumper to the clapper head, is 6 inches The multiple timbre setting clapper head has a diameter of 1 inch and a height of 5/16 inches The eccentric rubber bumper, which is located at the base ofthe support shaft, has a diameter of 11/16 inches and a height of 1/4 inch It is important to note that the dimensions for the above handchimes are nominal and will vary from chime to chime as the chime is tuned Finally, although the present invention has been described with reference to two exemplary embodiments, it will be understood by those skilled in the art that the invention is not limited to the embodiments specifically disclosed herein Those skilled in the art also will appreciate that many other variations ofthe specific embodiments described herein are intended to be within the scope ofthe invention as defined by the following claims.
