UNITED STATES PATENT OFFICE.

MARY F. OANNEY, OF GROVELAND, MASSACHUSETTS.

WIND=INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 387,338, dated August 7, 1888.

Application filed April 6, 1888. Serial No. 269,781. (No model.)

To aZZ whom it may concern:

Be it known that I, MARY F. CANNEY, a citizen of the United States, and a resident of Groveland, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Wind-Instruments, of which the following, taken in connection with the accompanying drawings, is aspecification.

This invention relates to improvements in wind-instruments, and it is carried out as follows, reference being had to the accompanying drawings, wherein- Figure 1 represents a side elevation, and Fig. 2 represents a central longitudinal section, of the improved wind-instrument. Fig. 3 represents a cross-section on the line A B shown in Figs. 1 and 2.

Similar letters refer to similar parts when ever they occur on the different parts of the drawings.

a represents a cylinder having open ends and provided midway between its ends with a solid partition or diaphragm, a, soldered or otherwise secured in an air-tight manner to the said cylinder (1, as shown in Figs. 2 and 3.

Within the cylinder (4 are arranged on opposite sides of the partition or diaphragm a the packed movable pistons b b, as shown in Fig. 2, and to each of such pistons is secured the inner open end of the reed pipe or horn 0, provided with a vibratory reed, 0, common to fish-horns and similar wind-instruments. The horns 0 c are connected together at a proper distance apart by means of the staywires d d, which pass outside of the cylinder at, thelatterhavinglongitudinal guides aaonits exterior surface for receiving said guidewires and to enable the cylinder (6 to be grasped without interfering with the free motion of such guide-wires when the instrument is sounded.

The instrument is operated as follows: The

operator holds the cylinder a in one hand and grasps the outer end of one of the horns c with the other and moves the cylinder (4 forward and back relative to the connected horns c c, or vice versa, thus causing the air to be intermittently admitted through the horns into the spaces between the stationary partition a and the movable pistons b b and to be intermittently forced out from such spaces through the reed-openings, thus causing each horn to be sounded while being moved rapidly toward the central partition, a. During such reciprocating motion of the horns or the cylinder (6 the bent ends d d of the guide-wires d (I serve as stops against the outer ends of the cylinder a to limit the movement of said parts, so as to prevent the inner ends of the horns or the pistons b b from coming in contact with the stationary partition a. By means of this instrument powerful intermittent sounds are produced, making it very useful as a foghoru or as a calling or signaling wind-instrument, or for other purposes.

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claim The wind-instrument as described, consisting of the cylinder a, having the partition or diaphragm a, and a pair of movable sounding-horns, 0 (2, provided with pistons b b and connected together for operation, as and for the purpose set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 29th day of March, A. D. 1888.

M ARY I GANNEY.
