ROWLAND H. MAYLAND, OF NEW YORK, N. Y.

DEVICE FOR PRODUCING A BUZZ EFFECT.

Specification of Letters Patent.

Patented Aug. 17, 1915.

Application filed April 2v 1914. Serial No. 828,999.

T 0 all whom it may concern Be it known that I, ROWLAND I-I. MAY- LAND, a citizen of the United States, residing at Brooklyn, in the county of Kings, city and State of New York, have invented certain new and useful Improvements in Devices for Producing a Buzz Effect, of which the following is a clear, full, and exact description.

The object of this invention is to provide a practical and advantageous means for obtaining a buzz effect accompanying the production of a musical note, either by means of a resonator properly equipped, or in an organ or pipe, that is to say an element providing a resonant air column. The present popular demand for a certain type of music has created a demand for a different effect than that produced by a clear tone.

In a practical application of the invention to tubular resonators, such as are used, for example, in Xylophones, the bottom of the resonator, instead of being permanently closed, is provided with an opening closed by a. thin mica disk held in position by a perforated supporting plate and a retaining spring, the diaphragm being capable of being vibrated upon the vibration of the air column in the resonator to produce the buzz effect. The device may be similarly applied, at .a suitable point, on an organ pipe.

IVhile the foregoing is the preferred construction, the invention comprises a number of features in which variation is permissible and not all of which need be utilized in each instance in conjunction with the remainder.

The scope of my invention will be pointed out in the claims.

In the accompanying drawings: Figure 1 is a side elevation partly in section of my improved device as applied to a Xylophone. Fig. 2 is a vertical transverse section through Fig. 1, one of the resonators being shown in section and the bar thereover in elevation. Fig. 8 is a bottom plan of the resonator tube or the closed end of an organ pipe. Fig. 4 is a sectional view of the rubber gasket. Fig. 5 is a sectional view of the mica buzz diaphragm. Fig. 6 is a sectional view of the retaining cup and spring retaining element. Fig. 7 is a side elevation partly in section of an organ pipe provided with the device of my invention.

As shown in the drawings: 1 is an ordinary Xylophone bar capable of being struck with a hammer to emit a definite tone.

Immediately beneath the center of the bar a resonator tube 2 is located, the air column inclosed by the tube being in tune with the particular bar above the same. The in terior of the tube is partly closed at the bottom by a wall 4 preferably of metal having a central opening 5.

The wall a is an extension of a cylindrical shell 6 having a turned-over edge or abutment 7, which is formed with an opening at S. The buzz device is disposed within the chamber thus afforded and comprises the buzz retaining cup or support 9 with numerous perforations 10 in its bottom fastened by a stud 11 to a retaining spring 12 pivoted on the screw 13.

A mica disk 14 is adapted to rest within the cup 9, and a rubber ring or compressible gasket 15 having a central opening 16 fits within the cup upon the diaphragm. The buzz device is inserted through the open end of the shell 6, introduction of the retaining spring 12 being permitted by the opening 8, as indicated in dotted lines in Fig. 3, and the spring being then turned so as to bear against the inner side of the flange, as shown in full lines in said view and in Fig. 2. The device is then ready for operation.

In Fig. 7, I have shown the same device shown in the other figures applied to a. closed organ pipe, but it is to be understood that the invention is applicable to other forms of organ pipe.

It will be understood that I do not limit myself to the precise construction shown and described, and that various changes are permissible within the scope of the invention, as indicated by the appended claims.

I claim as my invention 1. In a. musical instrui'nent, the combination with means providing a resonant air column, said means being formed with an opening into said air column; of a diaphragm of mica closing said opening and adapted to be vibrated by the vibration of the air column to produce a buzz effect.

2. In a musical instrument, the combination with means providing a resonant air column, of a diaphragm of mica closing an opening therein and adapted to be vibrated by the vibration of the air column to produce a buzz effect, a support adapted to hold the diaphragm in place, and a retaining spring act-ing upon said support.

3. In a musical instrument, the combination with means providing a resonant air column, of a diaphragm of mica closing an opening therein and adapted to be vibrated by the vibration of the air column to produce a buzz effect, and means for holding said diaphragm in place comprising a perforated supporting plate against which the diaphragm rests at its outer side.

4-. In a musical instrument, the combination with an element providing a resonant air column, and means forming a chamber communicating by an opening with said air column, of a buzz producer in said chamber comprising a diaphragm and means holding the same in place closing said opening so as to be vibrated by the vibration of the air column.

5. In a musical instrument, the combination with an element providing a resonant air column, said element having an opening, of a diaphragm closing said opening, and a perforated support against which the outer side of said diaphragm rests.

6. In a musical instrument, the combination with an element providing a resonant air column, said element having an opening, of a diaphragm closing said opening, a compressible gasket interposed between the diaphragm and the portion of the element having said opening, and means exerting presure on the diaphragm to hold the same against the gasket.

7. In a musical instrument, the combination with an element providing a resonant air column, said element having an opening, of a diaphragm closing said opening, a compressible gasket interposed between the diaphragm and the region surrounding said opening, a support at the outer side of the diaphragm, and a spring retainer acting upon said support to press the diaphragm against the gasket.

8. In a musical instrument, the combina tion with an element providing a resonant air column, said element having an opening, of a buzz producer comprising a cup, and a diaphragm held therein closing said opening so as to be vibrated by vibration of the air column.

9. In a musical instrument, the combination with an element providing a resonant air column, said element having an opening,

of a buzz producer comprising a cup having a perforated bottom, and a diaphragm held in the cup against said perforated bottom and closing said opening so as to be vibrated by vibration of the air column.

10. In a musical instrument, the combination with an element providing a resonant air column, said element having an opening, of a buzz producer comprising a cup having a perforated bottom, a diaphragm held in the cup against said perforated bottom and closing said opening so as to be vibrated by vibration of the air column, and a spring retainer secured to said cup and cooperating with a suitable abutment.

11. In a musical instrument, the combination with a tube providing a vibratory air column, of a shell within the end of said tube having an inner wall provided with an opening, and a buzz device within said shell comprising a diaphragm and means for holding the same in position closing said opening so as to be vibrated by vibration of the air column.

12. In a musical instrument, the combination with an element providing a resonant air column, of a diaphragm closing an opening in said element so as to be vibrated by vibration of the air column, and spring means for holding said diaphragm in place.

13. In a musical instrument, the combination with an element providing a resonant air column, said element having an opening and means forming a chamber at the outer side thereof, of a buzz device in said chamber comprising a vibratory diaphragm closing said opening, a support at the outer side of said diaphragm, and a retaining spring acting upon said support.

14. In a musical instrument, the combination with an element providing a resonant air column, said element having an opening and means forming a chamber at the outer side thereof, said chamber having an entrance opposite said opening and a retaining abutment, of a buzz device comprising a diaphragm with support insertible through the entrance of said chamber to close said opening, and a spring retainer connected to said support.
