UNITED STATES PATENT OFFICE. I

Specification of Letters Patent.

Patented Feb. 6, 1906.

Application filed December 31. 1904.. Serial No. 239,241.

To all whorn it may concern:

Be it known that I, JAMES T. BROWN, a citizen of the United States, residing at 1524- First avenue, in the city, county, and State of New York, have invented a new and useful Folding Phonograph-Horn, of which the following is av specification.

My invention relates to a horn especially adapted for use with phono raphs or similar devices; and it consists in the constructions, combinations, and arrangements herein described and claimed.

The objects of my invention are to provide a simple and durable form of collapsible horn which can be conveniently adjusted and which will be held rigidly it its expanded position.

Referring to the accompanying drawings, forming a part of this application, and in which similar reference-symbols indicate corresponding arts in the several views, Figure 1 is a si e elevation illustrating one embodiment of my invention in its expanded osition. Fig. 2 is a side elevation, partly In section, showing the collapsibleportion of the horn in folded position. Fig. 3 is a sectional view on the line 3 3 of Fig. 1. is a detail sectional view illustrating a preferred form of latch for locking the two pertions of the horn to ether.

Referring espeeia l to Figs. 1 to 4, 1 indicates the rigid mout piece of a horn, which may be formed of any suitable metal, and which is rovided with a tapered annular portion 2 or expandin the foldable portion of the horn. The fol able portion of the horn comprises a stiff sleeve 3, preferably formed of metal, to which an annular series of stifl ribs 4 are pivoted at 5. The sleeve 3 is provided with a tapered annular flange 6 for limiting the outward swin of the ribs 4 about their pivots 5, the limiting-flange 6 of the sleeve and the ex anding portion 2 of the mouthpiece preferab y being constructed with the same taper for the purpose of securely clamping the ribs 4 rigidly therebetween.

In the construction shown the ribs 4 are constructed of strips of metal bent in U- shaped form for clamping the ed es of the suitabl -arranged sections 7, of eather or other exible material. This construction permits a supporting means, such as a chain 12, to be secured near the outer ends of the ribs, thereby enabling the horn to be supported without undue strain.

The mouthpiece 1 carries a suitable latch 8 for securely locking thetwo portions of the horn together. As shown, especially in Figs. 1 and 4, this latch may be formed of sheet metal pivoted at 9 to the mouthpiece and provided with a lip 10 for engaging theend of the sleeve 3 when the parts are assembled, a thumb-piece 11 being provided for depressing the latch when it is desired to separate the parts of the. horn.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. Ahorn comprising a mouthpiece, aflexible portion, and cooperating means on said mouthpiece and flexible portion forv expanding the latter and clamping it in expanded position, substantially as described.

2. A horn comprisinga mouthpiece, aflexible portion, and cooperating tapered means on said mouthpiece and flexible portion for expanding the latter and clamping it in expanded position, substantially as described. 3. A horn comprising amouthpiece, aflexible portion, cooperating tapered means on said mouthpiece and flexible portion for expanding the latter and clam ing it in expanded position, ble portion on position, substantially as described.

4. A horn comprising a mouthpiece, aflexible portion, an annular flange carried by the flexible portion for limiting its expansion, and an expanding portion carried by the mouthpiece for expanding the flexible portion a ainst said flange, substantially as' describe 5. A horn comprising a mouthpiece, aflexible portion, a tapered annular flange carried;

by the flexible portion for limiting its expanand means for oeking said flexi the mouthpiece in expanded sion, and a tapered expanded portion Citl'llBd by the mouthpiece for expanding the flexible portion against said flange, substantially as described. I

' 6. A horn comprising a rigid mouthpiece section and a collapsible section, said collapsible section being expanded by a movement of one of said sections relatively to the other.

7. A horn comprisinp a rigid mouthpiecetelescoping within the latter and the latter section and a collapsib section, the former being expanded by a relatively longitudinal telescoping Within the latter and operative movement of one of said sections.

to expand the latter by a movement relative JAMES T. BROWN 5 thereto. Witnesses:

8. A horn comprisin a rigid mouthpiece- Mrs. L. H. SHERMAN, section and a collapsible section, the former FRANK CAPEK.
