In percussion musical instruments for use in combination with organ installations and the like, difficulty has been encountered due to the fact that the resonators or tone in- 5 tensiliers particularly 'for the low notes were articularly long and projected out of the ottom of the sound box of the instrument thereby requiring an extremely large amount of yspace to properly mountthe percussion instrument in an organ or any other place Where space is at a premium. Trouble has also been encountered in percussion instruments due to the mode of mounting or securing the resonators in the sound boi: without adequate facilities for preventing leakage of air.
This invention rel ates to an improved type of percussion musical instrument adapted for use in organ installations and the like, and
constructed with the resonators for the low notes divided into sections projecting in opposite directions from the sound box and parallel to the sounding bars to reduce air friction to cause intensification of the tones.
It is an object of this invention to provide a percussion type musical instrument wherein the use of long resonators is eliminated by the use of sectional resonators projecting in opposite directions from the sound box to permit the instrument to be conveniently mounted in a shallow compartment with both the resonators and the sound bars disposed in a perpendicular position.
It is also an obj ect ot this invention to provide a percussion type musical instrmneut having resonators inserted into grooved openings in the sound box through felt busliings and through washer plates of insu1 ati ug material whereby an airtight or non-lea ing joint is provided between the resonators and the sound box to securely hold the resonators in a suitable position.
It is an important object of this invention to provide an improved percussion type musical instrument wherein the sound box is arranged to receive the resonators constructed in sections with said sections projecting in opposite directions from ,lie sound bof; and parallel to a. sound bar with the inner ends of said resonator sections projecting through 1"" I'QHLER-LEIEBCH COW QF son on ni. .rRUMn-ufr cca-:es
felt bushings and through sound insulatingwasher plates u" i are adjustablv mounted on the exterior c `ie sound box bt* Inca-ns of screws or the like to permit compression of the felt bushing to insure an` airtight fit around the seainiess resonators to securely heid the same in a itable position.
Other and further important objects of this invention will be an arent from the disclosures in the specifica on and the accom-vv panying drawings.
This invention (in a preferred form) is illustrated in tbe drawings and hereinaftery more fully described.

As shown on the drawings:
The reference numeral l indicates a shallow case or boi; wi may form a portion; of an organ and which serves a support within which a plurality of improved percussion type musical instruments may be supported in parallel horizontal relation, thereby requiring a comparatively small amount ot' tloor space. As illustrated in Figure l, three different types ot percussion instruments are illustrated.
The middle or intermediate percussion instrument will now be described in detail. lThis instrument comprises a sound box or sound reflecting memberI constructed ot wood or other suitable material, said box comprising a back wall Q and a front wall 3 which is supported opposite the back wall 2 by means of a top wall l and a bottom wall 5. The ends ot the sound box are closed by end walls 6. The sound box is divided into a plurality ot chambers 7 (Figure 2) formed by a pluralityT of partitions 8 disposed parallel to one another transversely of the sound box. The iront wall 3 of the sound box is provided with a row ot' apertures or openings 9, one for each of the tone chambers 7.
Secured at spaced intervals on the front wall 3 of the sound box are a plurality of screw eyes l() and l1, respectively. Threaded through the upper screw eyes i0 a single heavy silken cord 1Q, and threaded through the lower screw eyes ll are two silken cords 13. The ends of the cords l2 and 123 are secured to tno end screw eyes. The silken cords l2 and 13 are provided tor the purpose of' supportino` plurality of metal or wooden tone bars l-lwhich are graduated in length in the arrangement illustrated in Figure l to produce the required notes oi a musical scale when the sound bars are struck to vibrate thc same.
Each ot the tone bars lst has inserted through an aperture near the upper end thereot a retaining screw l5 each of which projects through a rubber insulating sleeve 1G and through a. suitable Jfelt washer l? engaged on the outer end of each screw between the tone bar and the head ot thn screw (Figure G). The apertured ends of the tone bars lst rest on Lhe cord l2, while the lower or opposite ends oit' the tone bars are disposed between the double cords i3. Each of the tone bars or sound members lst is mounted to permit free vibration thereof in response to a blow imparted thereto to give forth the desired tone. The tone bars are mounted so that each bar is disposed in trout ot a sound box opening 9 each communicating with the sound chamber T for that particular tout` bar. rlhe tone bars lelare arranged with adjacenttone bars four semitones epart thereby aii'iording an arrangement which eliminates the disagreeable tone interference perceptible in pere ion instruments wherein the bars are not mounted by this method. By suspending the tone bars on the single contact points properly insulated at their nodal line insures unhindered and perfect vibrations ot the bars.

The resoiiator tubes which are closed at the outer ends mar be cylindrical, square, oc )enel or of ani.' preferred shape desired. i'
The particular mode ot insertion ot the resonators Q5 affords a tight tit tor the resonators obviating the leakage ot air from the sound box betweer the ref-onato.Y` and the sound box openings in which tlev are engaged. I
The middle percussion instrument is arranged with the re. nators parallel to the tone bars A, thereby ador fr an instrument which requires a small am it ot space when installed in an organ or any place whore the space is at a premium. ln this torm ot nercussion instrumcT the tone bars are' arranged in two gro s, The tone bars for the first group ar mounted on the lett hall of the sound boi-. loolrino; at Figure l` and comprise the tones C, ll). if i ,I .i D. The second group o tone 'bals are mounted on the right halt of the sound box looking at Figure l, and comprise the tones it, F', il, B, G and The tone bars tor each group are ari th the are t hars` near the ends and i i-h t ie other bai". in Ql'aduatcd relation irwardlv t center from both ends ot 'the gr .p portant feature ot the novel arrangement ot the tone bais oit each groin.) lies Iii the 'tact that the tones of adjacent tone lia i irc tour semitones apart which allows increased vollid Lme'roi 3 ment withv one another and are associated with and parallel to a particular tone bar as clearly illustrated in Figure 1. The use of the sectional resonators replaces the single long resonators heretofore used and",
I furthermore, reduces the friction 'of the air over thatl encountered inv long resonators so that in the present method the use of thev sectional resonators reduces the friction of the air traveling in the resonators and thereby greatlljr intensifies the tones produced. Associated with the tone bars G# and A# of the first group and A and B of the second group, are single or onel piece resonators which project upwardly from the top sound l box: wall 4. There areno openings in the bottom sound box wall 5 associated with the tone bars Git, A JHE, and A and B. It will thus be noted that the lower tones of each group of tone bars have sectional resonators associated therewith, while the higher tones only have unitary resonators associated therewith which are graduated in length depending upon the tones.
By providing a percussion instrument with sectional resonators where needed parallel to their respective tone bars, an instrument is provided which may be mounted in a coinparatively shallow recess or box which is highly desirablev in organs and similar instruments where the floor space is extremely limited.
The upper and lower percussion type musical instruments illustrated in Figure 1 are constructed similar to the middle percussion instrument and the resonator tubes for the lower notes of said instruments are mounted in the tone box similar to the arrangement illustrated in Figures 5 and 6 of the drawings. The shorter or high pitched tone bars of the lower and upper instruments are mounted above openings in the sound box front board, and said openings have associated therewith short resonator cylinders of different lengths depending upon the respective lengths or size of the tone bars with which they are associated. The end tone bars of these instruments have sound compartments associated therewith with the compartments for the lower notes having resonator tubes projecting therefrom. The upper The mode of suspension of the tone` and lower percussion instruments illustrated in Figure 1 and the detailed showing of the upper instrument as illustrated in Figures 3 and 8 are not described in detail since an adequate detailed description has already been given in connection with the middlei instrument which covers all of the patentable features of the present invention. While cmbracing the improved mounting for the resonator tubes they do not embrace the use of sectional resonators. The showing of the three types of percussion instruments is used to illustrate the possible combination of percussion instruments of this type for use in organs and similar instruments.
I am aware that many c. anges may be made and numerous details of construction may be varied through a wide range without' departing from the principles of this invention, and I, therefore, do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.
