"sncrrroniui norm FOR TALKING-MACHINES.

Application filed July 15,1907. Serial 1%. 233,736.

To all whom it may concern:

lie-1t known that I, ELLswoR'rH AfHAw- 'rnonxn, a citizen of the United States, re-

siding in Philadelphia, Pennsylvania, have invented certain Improvements in Sectional Horns for Talking-Machines, of which the following is a spec fication. f

My invention relates to sectional horns such as are sometimes used in connection.

- when so fitted together, will berigidlyheld in their proper relation one to another; a further object being to so construct the sectional members of the horn that when they are fitted together, the horn will present,

7 both interiorly and exteriorly, a symmetrical appearance. 1

In the accompanying drawings-:.Figure -1 1s a side elevationof my improved SBCtlOIlEll' horn showing the members of the same fitted together for use, but illustrating themouth piece detached from the bell portion of the horn; Fig. 2 is a similar View illustrating the sections of the horn detached from one another, and fitted one within the other; Fig. 3 is a transverse section on the line a-a, Fig. 1; Fig. 4 is a transverse section on the line 6-6, Fig. 1, but on an enlarged scale, and Fig. 5 is a transverse section on the line 0-c, Fig. 1, likewise on an enlarged scale.

I have, in the present instance, illustrated -my invention as embodied in a horn having abell portion of octagonal cross section, although the invention is applicable to'horns of other contour in cross section. The bell portion of the horn is composed of two sec.- tions 1 and: 2, each of which may consist of a single piece if desired, althoughas shown each consists of four strips secured together by interlocked joints 3'.

horn anequivalent of the joints 3 is pro- Qducedby providing the edges of the sections with projecting flanges 4 and sockets 5 for -the receptidh of said flanges, as shown in Where the sections join each other on each side of the Fig. 3, each flange being slightly offset. from the member on which .it is formed, so as to accommodate the inner wall of the corresponding socket 5, and thus preserve the symmetry of the interior surface of the horns 'Each section of the horn has, at each side a series of pro ecting lugs (3, and to each lug of one section 01' the horn is itastened a swinging book i which engages with a catch 9 on the corresponding lug oftho other section in order to lock the two sections of the horn 1n their proper relation one to another.

In order to insure the proper registry of v the two sections at the mouth piece end of the trumpet, each section is, at that point, thickened on each side as shown at 10, in Fig. 4, two of these thickened portions carrying dowel pins 11 which enter sockets 1-2 in the other thickened portions. At'\the mouth piece end of the horn the bell portion of each section has a projecting semi-circular extension 13, each of these extensions having its edge portion stiffened by means of a wire 14 as shown in Fig. 5, and one edge of each extension has a projecting flange lo-overlapping the reinforced edge of the other section, this construction also serving to maintain the two sections in proper registry with one another.

The month piece consists of a flaring tube 16 adapted to fit over the nozzle formed by the projections 13, and havingin one side an inclined slot 17 which engages a projecting lug 19 on a corresponding portion of the nozzle so as to lock the mouth piece in engagement therewith, when it is properly adjusted upon the, nozzle, ready application for removal of the mouth piece being thereby provided for. stitute, in eii'ect,"part of a screw threaded connection and a complete thread may be used ifdesired.

hen the two sections of the horn are dis-' connected they may be fitted one within the other as shown inFig. 2 so-as to occupy much less space than the complete horn, and when the parts of the hornare thus fitted Patented Oct. 5,1909.

The slot- 17 and lug 19 contogether, they can be conveniently packed in a trunk or sample case.

I claim ,1. A horn for talking machines composed of sections each consisting of a series of strips rigidly united at their edges by means 2. A horn for talking machines composed of sections each consisting of a series of strips having their meeting edges rigidly connected by means of interlocked joints,

the edges of the sections engaging by means of a socket on" one section and a flange on the other section entering said socket, and the sections being secured together-by means of external, separable fastenings.

3. A born for talking machines composed of sections each -cor'nprising a bell member and a mouth piece or nozzle member, said sections having abutting edges, and the edges of the nozzle member being rolled and provided with internal stiffening wires,

4. A horn for talking machines composed of sections each comprising a bell member and a mouth piece or nozzle-member, said prising a bell member and a nozzle member, said sections abutting at the edges, and the nozzle member having an external detachable mouth piece which serves to retain the laterally separable sections ot the said nozzle member in contact with one another.

In testimony whereof, I havesigned my name to this specification, in the presence of two subscribing witnesses.
