' which the following is a description.

My invention relates to phonographs and particularly to ports therefor.

In order to secure the best lresults from a phonograph it has been found necessary to make use of horns of relatively large dimensions. Such horns are usually supported from the phonograph cabinet by some form of horn crane so that they extend outward in front of the phonograph to a considerable distance. The'obj-ections to this form of apparatus are numerous; for example, a horn so supported takes up a large amount of room, and it has a tendency to upset the phonographv or toftvvist and bend the parts thereof. Such a horn can-only be partially supported from the horn crane, and it is necessary-in order to secure `stability that a considerable portion of its weight be borne by the reproducer or recorder of the phonograph, and this to a considerable extent interferes with the movements of the phonograph carriage, and imposes wear on the line feed screw. The horn extending out to the front is often in the way of the operator, and it is difficult direct such a horn so supported toward any given point without turning the phonograph bodily around. Again, it is ditlicult to replace the cover upon the cabinet, after the instrument has been used, as t-he horn is always more or less in the way, and it is often found necessary to entirely remove the horn from the phonograph and crane before the cover can be placed upon the cabinet.

It is the object of my invention to do away with the objections which are present in the horns and supports therefor now in common use, and l. obtain these results by mal:- ing my improved horn of such form that it may be support-ed above the phonograph instead of extending out in front thereof, as is the common practice. By making the horn of my improved form .l am enabled to support it from a point vertically above its center of Specification of Letters Patent. Application sled october 14', 1907.

instability which would be caused if the horns now in use were so supported. It is possible to do this with my improved horn for the reason that its center of gravity is at a relatively considerable distance beneath the point -of support. My improved horn is loosely connected with'the reproducer and none of its weight is borne thereby, as has beenthe case With horns supported in the old way, andit therefore does not interferein any way with the movements of thecarriage. The `horn being entirely supported from above at a point vertically over its center vof gravity can readily be turned in any direction so that the sound may bedirectedto any point Without the necessity of vturning the phonograph about to a new position upon the table or other support, and the-horn being suspended above the cabinet takes up but little space in a room, and need not'be removed in order to replace the-cover upon the cabinet, but may be readily pushed to one side to permit. the placing of the cover in position `and the horn need not be removed from its crane when the phonograph is out -of use, but may remain suspended from its crane at all times, and when it is desired toA operate the phonograph it is only lnecessary to A remove the cover and connect the lower end of the horn to the reproducer.

YWith the above .and related objects in View, my invention consists in the parts, improvements and combinations hereinafter set forth and claimed.

In the accompanying drawing, forming a part of this specification, and wherein the same reference numerals areuniformly used to designate the same parts, Figure l is an end elevation of a phonograph provided with my improved form of horn and horn support, the connection between the tube of the reproducer and the horn being shown in section, and` Fig. 2 is a view partly in section Vand partly in side elevation of the reproducer, and a connecting the horn thereto.

l represents the phonograph cabinet and 2 the carriage which is movable transversely of the mandrel 3 and supports the reproducer 4. Of course instead of a reprmlucer, a recorder may be used, as is well understood, the term sound box used in the portion of the means for 2 roscas@- claims being intended to designate either of these devices. vIn the preferred form of my invention, the reproducer or recorder is supported horizontally in the carriage' 2, Aso that the neck 5 through which the sound 1ssues therefrom is substantially vertical.

My improved horn comprises a bell 6, a tapering elbow 7 secured to the smaller end ot the bell, and a tapering tone arm 8 secured to the smaller end of the elbow. The longitudinal aXis of the tone arm and the longitudinal axis of the bell it continued -would meet in an angle which is preferably somewhat less than a right angle. The tone arm is loosely and-exibly connected to the neck 5 of the reproducer by any suitable means The connecting means which I have shown comprises a iiexible rubber tube 9 and a short cylindricaltube 10, the inner diameter of which is somewhat larger than' the outer diameter of the neck 5 of the reproducer, and which is provided with an inwardly extending bead or iange 11 at its lower end, which iits fairly closely -about the reproducer tube but not so close as to bind thereon. Itwill be evident that by reason of the bead 11 this cylindrical tube 10 may be tilted with respect to the reproducer neck 5 through a considerable angle. An outwardly extending bead or iiange 12 is formed on the upper end of the tube 10 over which the rubber sleeve 9 frictionally engages. Supporting means is provided for this 'horn at a point directly in line with the center ot gravity thereof. It is desirable that the horn shall be capable of being turned upon this supporting means so as to face in any desired direction and at the same time, that suiiicient stability shall be secured to retain the horn facing in any direction. i have therefore made the support in the iorm of a rodl-B provided with a. bali 11i which lits within the socket piece 15, secured to thebell 6. This rod 13 isi-supported by the upper end 16 of a horn crane. is shown, the rod 13 is threaded at its upper end and after passing through the end 16 of theupper portion of the crane it has a nut 17 screwed thereon, but it is evident that other forms ot connection may be used. The lower portion of the horn crane comprises a substantially verticalrod 18, which is secured in socket pieces 19 at the back'ot the phonograph cabinet and held in place by'set screw 20. ltis to be understood, however, that other forms of cranes and other means ot' connecting the crane to the phonograph mav be used if desired. The portion 18 of the crane is hollow and the upper,part'16 ot the crane tits therein and is held from rotation relatively to the part 18 by meer et a pin 21 passing through the upper poi ien 16 of the crane, and fitting in shallew notches 22 in the upper end of the crane section 18. As is shown in the drawing, the lower end of the tone arm, which is adapted for connection with the recorder or reproducer 2 is directly beneath the support 13 and the center of gravity of the horn.
