SPECIFICATION forming part of Letters Patent No. 270,543, dated January 9, 1883.

Application tiled August "1S, 1882. (Model.)

To att 'whom it may concern: imitations ot' birds and animals, as the caw of Be it known that I, VARREN HERBERT a crow, the crow ot the cock, the moo of a FROST, a citizen ofthe United States, residing cow, doc. at dorcester, in the county of lVorcester and As the diaphragm E is liable to breakage 5 State otl lllassachusetts, have invented a` new by contact with other bodies when the toy or 55 and novel 'loy or Musical lnstrun'ient,of which instrument, as previously described, is carried the following is a specitication. loosely in' the pocket, l have invented a means My invention consists ot' a new and novel ot protecting the same by covering the diatoy or musical instrument, ot' which thet'ollowphragm E with a solid body when the toy or, [c ing is a description, my objects being, tirst, to instrument is not in use and exposing the dia- 6o pi ovide, in a compact and convenient torni, an phragm E to the air when the toy or instrument instrument or toy which will impart a vibrais to be used.

thus making the toy or instrument capable of avast variety of sounds.

I am aware thata toy or musical instrument is made which imparts a reedy sound tothe voice, as does my invention, by the vibration of a diaphragm. It is made in the form of a tube with a diaphragm over one or each end, with au opening in the side of the tubenear the end, into which opening the voice is sent to produce a sound; but in playing such an instrument it must be heldin the position of a ife or flute, and is inconvenient and clumsy; whereas iu my improvement the sound comes in a straight line from the mouth through the instrument, vibrating the diaphragm E in its passage, making the toyor musical instrument of an attractive and convenient form.

If the diaphragm E is entirely shut oi' from contact with the outside air, it will not vibrate, though the diaphragm may be partly covered and still work. l

I can cover the diaphragm E with any suitable material which has one or more openings through which the sound-waves from the diaphragm E can reach the outsidel air, While the openingoropenings maybe made ot' such small size as to leave enough solid material over the diaphragm for the purpose ot' protecting said diaphragm. For instance, a piece of tin with the four small holes, while the tin protects the diaphragm E at the same time.

I am not aware that anything similar in construction to my invention has ever been made; and

That I claim, and desire to secure by Letters Patent of the United States, is-

1. A toy or musical instrument which imparts a reedy or vibratory sound to the voice, made in a tubular or cylindrical forni, with a hole, B, extending through its length, and a hole, C, joining the hole I3, with a diaphragm ot' thin material over the open end ofthe hole C, substantially as described.

2. The combination,with such toy or musical instrument, of a solid material nearly or entirely covering the diaphragm for the purpose of protecting said diaphragm, substantially as shown.

3. The com binatioinwith such toy or musical instrument of r-,yliiidrical shape from M to N, of a tube or hollow cylinder, F, with one or more holes at Gr, which tube or hollow cylinder is capable ot' being turned on such toy or musical instrument so that eitherthe hole or holes at G or the solid portion ofthe tube F can be brought over the diaphragm E, substantially as shown, and for the purpose set forth.
