MARTIN L. MUNSON, OF NEW YORK, N. Y. i romance ,PHonoenAsHio Hons.

To rail wltmn it may concern:

Be it known that I, MAR-rm L. h iUNSON, a

citizen of the United States, and a resident the city, of New York, borough of Manhattan, in the county and State-of New York, have invented a new and Im roved Folding Phonogra h-Horn, of which the following is a full, clear, and exact description.

This invention relates to horns such as are attached to phonograplis or similar instruments for intensifying sound and throwing itin a desired direction.

The object of the invention is to roduce a horn of simple construction WlllOl may be folded so as to occupy a small space, enablin the horn tehscoovenienily carried or packed for transportation... r

The. nvention consists in the construction and combination at parts to'be more'iull described hereinafter, and definitelyset fort. in the claims. I

Reference is to be had to the accompairying drawings, forming a part of this specification, in wlnch similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of the horn, representing the same in its opened or ex Fi 2 is a longitudinal vertical section of the rorn when expanded as inv Fig. 1, and Fig. 3 is a side elevation showing the horn in a folded or collapsed condition. 1

Referring more particularly to the parts, 1 represents the bodyof the horn, which is preferably composed of leather, cioth, metal,

aper, or similar collapsible material. This liody has the same general form as usually found in horns of this kind, comprising a oontracted neck 2, which attaches to a nipple or mouthpiece 3. As indicated, the mouthpiece 3 is preferablyo'f conical form and should be constructed of metal or similar material. At the inner or large extremity of the mouthpiece a lurality of ribs or stays 4 are attached ri d and these sta spref erabl consist of at strips or bars 0 metal,

at sides whereof are attached longitudinally to the body- 1 of the horn. Near their outer extremities these stays 4 are connected by a plurality of links 5, arran ed be-' tween the stays and pivotally attache theres test the oints 6, as will be readily'under stood. 'T was links 5 are formed with centrally-disposed joints 7, which joints ,break inwardly or in the direction of the moutln' piece. At the joints 7 pull-rods 8 attach,

. andf these'extend toward the mouthpiece 3 I and are attached to a movable ring or collar 9. TlllS collar 9 has preferably the form of a When the links 5' are all straightened out or extended, as indicated in Fig. 1, they opcrate to maintain the metal frame of the device in its most expanded condition. The construction of the joints 7 is such that when the horn-frame is opened out, asindicated, the horn will maintain itself in this open condition. When it is desired :to fold the horn, the ring or collar 9 will be grasped and forced in the direction of the extremity of the mouthpiece. In this way the pull-rods 8 oper ate upon the links 5 so as to reak the joints 7. In this Way theouter extremities of the stays or ribs 4 are brou httogether, and when completely folded tie body 1' of the horn will collapse'so that the horn will present substantially the appearance shown in Fig. 3. When in this condition, the horn may he veryconveniently carried about or packed for shipment and may be readily opened out for immediate use when desired.

It should be observed that the metal parts of the horn when attached together consti- I tute a light framework or frame givin the open horn the required form. It 'shou d be understood that when opened out theconnested links 5 constitut'e'a jointed ring completely encircling the bod of the horn.
