SPECIFICATION forming part of Letters Patent No. 739,954, dated September ZQ IQQQ 7 i Application filed ce ber 81 1902. Serial No. 134,413. (No model.)

To all whom it may concern:

Be it known that I, GUSTAVE HARMAN VILLY, a subject of the King of Great Britain and Ireland, residing at 5 Longford Place, Iiongsight, Manchester, in the county of Lancaster, England, have invented certain new and useful Improvements in Connection with Horns for Phonographs, Ear Instruments, and for Like Purposes, (for which I have made application for Letters Patent in Great Britain, No. 20,1l6, and dated 15th day of September, 1902,) of which the following is a specification.

This invention relates to improvements in connection with horns or trumpet-like sound distributors or collectors for use upon phonographs, gramophones, and other like instruments and also for ear-trumpets, fog-horns, and other sound distributing and collecting devices, the obj eet being to provide a horn or trumpet-like device which can be folded when not in use, so as to be capable of ready transportation and for placing within the case of the phonograph or in the pocket of the user when it is to be applied to an ear instrument or the like.

The accompanying drawings represent one form of the invention.

Figure 1 is an elevation of the complete or erected horn. Figs. 2, 3, and 4: are detail views illustrating the manner in which the horn can be collapsed or folded. Fig. 5 is a perspective-view illustrating one convenient application of the improved horn to aphonograph. Fig. 6 is a detail view on an enlarged scale.

In carrying my invention into effect in one convenient manner when making my folding horn for use, particularly in connection With a phonograph or like instrument, I make the end a of trumpet-like or curved configuration with an enlarged outer end and a smaller end at the interior of the conoidal-like form. I make this enlarged and trumpet-like device by employing a series of strips b, of paper, wood, linen, or other preferably flexible material, the foundations of which I prefer to make of linen or the like, so as to form a hingelike connection 0 between each of the strips, the members I) of which I arrange so that while lying close together when extended there is a dividing-line between them about which they can be folded upon the base of linen or the like connecting-web upon which the paper or other material is mounted. The longitudinal hinged edges 0 of the flexible segments or sectors 1) are curved in such manner that although the segments when opened out cannot lie in the same plane they can either be folded together in a zigzag manner, so as to lie parallel to one another, as shown in Figs. 2 to 4, or extended by springing or buckling into the requisite trumpet or belllike form, as shown in Figs. 1 and 5. The angles formed by the meeting of the hinged segments when extended form, as it were, ribs, giving rigidity to the trumpet form. The outer ends of the segmental-like strips I prefer to protect by a bent or turned-over edging cl of metal, making the connection rigid by pressing a portion of the strip of metal or other binding material into the edge of the paper or the like foundation.

' Upon the extreme member c of the series of strips I) thus formed into one band I provide eyelets f or other clip-like devices for enabling snap projections 77. on the opposite end strip 9 to be engaged therewith and when thus engaged to form a completed trumpet-like sound-distributer.

Instead of arranging eyelets or hooklike 'clips upon the outer membersof the series of strips I may make one to engage with the other by forming a beadlike connection or flange upon one member, into which the corresponding projecting or engaging portions of the other may enter, as shown in Fig. 6. IVhen providing for an extension and a long funnel-like carrier for the builtup trumpet-like end a to engage with, I sometimes make a conical tube Z, the enlarged end of which engages with theinner end of the trumpetterminal a, while the smaller end of the cone engages with the receiver m of the phonograph or enters into the rubber or other tubular or flexible connection which may. be employed for use upon any particular instrument. I prefer to make this extended or carrying member Z for the collapsible trum pet from paper or other suitable material built up in a similar manner to that hereinbefore described to my collapsible end, or the cone may be made in a short length in one piece, or it may be made telescopic when so desired.

When providing for a flexible connection at the extreme end of the cone Z, I attach a length of rubber or the like tubing 11, which I bind with metal or other band at the end for the purpose of inserting it upon the funnel 0 of the phonograph-reproducer, and I stiflen the combination trumpetand funnel with flexible end by providing one or more bars 1) of metal or the like stiffeners which support the funnel by means of elastic or other connections q, arranged upon the cone end and suspended from the projecting stiffening hook or members p, carried from the metal end or binder of the flexible tube a.

When constructing a funnel or tube for an ear-trumpet or for a fog or speaking horn or the like, I employ the same method of building up the segments to form the expandingsurface, modifying the arrangement of the inner end to suit the connection that is to be made therewith, so that'when the trumpet is in use it can be extended and a large outer area exposed for the collection of sound and when not in use it can be folded, each segment upon the other, so as to occupy but little space-that is to say, a trumpet such asillustrated in Figs. 1 to a would be suitable as an ear-trumpet. r

I am aware that it has hitherto been proposed to form conical or pyramidal horns from cardboard provided with a linen foundation; but such horns have been made up from a single flat scored sheet or from a number of flat triangular strips having straight edges. Such horns could be developed or laid out upon a flat surface. Owing to their formation if such horns were made collapsible they would have to be sustained in their conical form by additional sustaining means, or if they were made self-sustaining they could not be made collapsible. In contradistinction to this my collapsible horn could not be made up from a single flat sheet, as each strip has to be made with curved edges, and when the strips are flexibly secured together at such curved edges the whole or complete surface so formed cannot be laid out or developed on a flat surface. My horn, owing to the curvature of the edges of the strips, is self-sustaining and requires no additional stiffening or sustaining devices, although when it is desired to collapse the horn this may be effected by forcibly straightening and folding the strips one against the other in the manner hereinbefore described with reference to Figs. 2, 3, and 4. The horn when erected oflfers a decided resistance to such straightening or folding sufficient to render it self-sustainin g against all ordinary shocks liable to be encountered; but it is found that when one strip has been forcibly straightened or folded I against another the equilibrium of the trumcollapsed.

I do not limit the application of my invention to any particular method of building up the segments or to any special curve or configuration of the same, and I vary the method of jointing and stiffening them to suit the material from which the strips are constructed and the foundation or base fabric upon which the flexible material forming the strips is secured.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A collapsible but selfsustained phonograph-horn, ear-trum pet or the like comprised of a number of flexible strips having curved meeting edges substantially as set forth.

2. A collapsible but self-sustained phonograph-horn, ear-trumpet or the like comprising a number of flexible strips having curved meeting edges and mounted on a flexible foundation, substantially as and for the purposes hereinbefore set forth.

A collapsible but self-sustained phonograph-horn, ear-trumpet or the like comprising a number of flexible strips having curved meeting edges, a flexible foundation for said strips and means for detachably securing the two extreme strips together, substantially as set forth.

4. A collapsible but self-sustained phonograph-horn, ear-trumpet or the like comprising a number of flexible strips having curved meeting edges, flexible connections between such edges and protecting means on the outer exposededges, substantially as set forth.

5. A phonograph-horn, ear-trumpet or the like comprising a rigid conical tube and a collapsible trumpet-shaped mouth the latter be ing made up of a number of flexible strips having curved meeting edges, and flexible connections at such edges, substantially as hereinbefore set forth.

6. A horn of the class described comprising a rigid conical tube, and a collapsible trumpet-shaped mouth made up "of a-number of flexible strips having curved meeting edges, said mouth being connected to said rigid conical tube, substantially as described.

7. A horn of the class described comprising a rigid conical tube, and a collapsible trumpet-shaped mouth made up of a number of flexible strips having curved meeting edges, said mouth being telescopically connected to I said conical tube, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

GUSTAVE HARMAN VILLY.
