Gladstone, New York, N. Y. Application May 25, 1935, Serial No. 23,422 3 Claims. (Cl. 84—422) The device of my invention relates to hammers for percussion musical instruments and is particu larly adapted for use with percussion musical instruments in which the tonal elements are of 5 separated members. - The production of musical composition from percussion musical instruments in which the tonal elements are separated, as in xylophones, chimes and similar instruments, is accomplished. by strik 10 ing the tonal elements by means of so-called “hammers” which consist of a hammer member, or head, carried by a ?exible and resilient handle. As the tonal elements are frequently struck with great rapidity, it is necessary that the handle 15 have suf?cient resiliency to return the hammer to its original position after its ?exing due to its percussion with the tonal element. This is the most important element of per cussion hammers, because if the handle is still 20 returning to its original position when the fol lowing tonal element is struck, the produced tone will be imperfect. Further, as the musician always employs two hammers be hollow and made of resilient and ?exible material, the devices have all of the de scribed advantages and that, therefore, they are a great improvement and have many valuable advantages over the present known devices nd are capable of greatly improved and more desir 15 able tonal effects. Without limiting myself to any particular re silient and, ?exible material, I ?nd that vul canized rubber and synthetic resin compositions are particularly suitable for my purpose. While I have referred particularly to the em 20 ployment of my devices with percussion musical instruments in which the tonal elements are sepa and resiliency as otherwise the tone effects will rated from'each other, I do not limit myself to such use as they may be equally advantageously employed with drums and similar musical in 25 struments, in any case where it is desirable to have be irregular and imperfect. both resiliency and ?exibility. or more hammers at the same time, it is essential 25 that all of the handles have the same ?exibility During the production of a musical composi tion upon a percussion musical instrument, the musician frequently ?nds it necessary to rapidly change his hammers, dependent upon the hard ness of the hammer head, in order to obtain the proper tonal e?ects and hence it is desirable that the hammers should carry some clearly de?ned 35 constant resiliency and suf?cient strength to pre vent their breakage during use. Further, the modi?ed forms of my device possess readily recognized insignia indicating tonal values and means for preventing the handle from slipping through the hand of the performer in addition to the advantages above mentioned. I have found that if the handles of percussion and rapidly recognizable insignia indicating the desired device. ‘ The advantages of my percussion hammers will be evident upon a consideration of my ‘speci?ca tion and its accompanying drawing in which 30 similar parts are designated by similar numerals. In the accompanying drawing Figure 1 is a‘ side view of one form of my device, partly broken away for purposes of explanation. Figure 2 is a top view of the device of Figure 1. 35 Figure 3 is a bottom view of the device of Fig Further, because of the force of the blow of the hammer head necessary in the production of some musical compositions it is desirable that 40 the handle portion be of such strength that it will not break under such percussions. The handles of the percussion hammers now employed are made» of rattan, but these possess many disadvantages among which may be men 45 tioned their-non-uniformity and non-rapidity of ure 1. resiliency, their property of remaining bent in stead of returning to a straight position, their loss of resiliency and ?exibility during use and their brittleness resulting in their being fre 50 quently broken during use. ure 5. The percussion hammers of my invention over come all of the above mentioned and other ob jectionable features of the present employed de vices, and present percussion hammers having 55 uniform and. constant ?exibility, uniform and Figure 4 is an enlarged section through the line 4-4 of Figure 1. Figure 5 is a side view of a modi?ed form of 40 my device showing its ?exibility. Figure 6 is a top view of the device of Figure 5. Figure '7 is an enlarged section through the line 'l--'| of Figure 5. Figure 8 is a bottom view of the device of Fig 45 The particular form of the device of my inven tion shown in Figures 1 to 4 consists of a resilient and ?exible hard rubber tubular member I 0, pref erably vulcanized upon both the inner and outer 50 faces, the lower end of which extends into and is ?xedly attached to a spherical knob member I I, which acts to prevent the handle from slipping through the hand of the user. The upper end of the tubular member H] ex 55 2. 2,040,603 tends through and is ?xedly attached to the spherical striking, or hammer, member [2 com posed of soft rubber, and a plug I3 is inserted within and is ?xedly attached to the tubular mem ber l0. ' The plug l3 carries a designating insignia as the numeral 5, and the spherical member H car ries a similar designating insignia as the nu meral 5. The modi?ed form of my device shown in Figures 5 to 8, consists of a resilient and flexible synthetic resin hollow cylindrical member [4, the lower end of which is inserted within and ?xedly attached to a spherical knob member l5, 15 and the upper end of which passes through the spherical striking, or hammer, member IS. The spherical member l5 and the hammer end I6 carry a designating insignia as a red color IT. The ?exibility of the device of Figures 5 to 8 is 20 shown by the dot and dash lines of Figure 5, the resiliency of the hollow cylindrical member I4 bringing the device to its original position as shown by the full lines of that ?gure. The hammer element of my device may be com 25 posed of wood, metal, felt, synthetic resin, cellu loid, Pyroline, bone or other suitable material, but I prefer to employ semi-soft rubber, the soft ness being adapted for the particular purpose for which it is intended, and which may be softer 30 or harder in different hammers, dependent upon the tonal effects desired. The designating insignia may be of any char acter which will designate the particular ham mer possessing a desired physical character, and the spherical member at the lower end of my de vice may be omitted if desired. It will thus be seen that my device possesses the property of greater assurance of the produc tion of proper tones, more uniform tonal results, more uniform ?exibility and resiliency and great er stability than the percussion hammers pre 10 viously employed. I do not limit myself to the particular size, shape, number, arrangement or material of parts speci?cally shown and described as these are given simply as a. means for clearly describing the de— 15 vice of my invention. What I claim is:— 1. In a hammer adapted for use with percussion musical instruments in combination, a hollow resilient and ?exible plastic composition handle 20 and a hammer head carried by one end thereof. 2. In a hammer adapted for use with percussion musical instruments, in combination, a hollow synthetic resin resilient handle and a hammer head carried by one end thereof. 3. In a hammer adapted for use with percussion musical instruments, in combination, a hollow hard rubber resilient handle and a hammer head carried by one end thereof. 30 WILLIAM D. GLADSTONE.
