' TALKING-MACHINE ATTACHMENT.

cation.

My invention relates to machines commonly known as talking-machlnes, and has for its object to providea simple and eiificient device for supporting the sound-conductor which is 'usually employed for conveying the sound from the vibrating diaphragm to the amplifying-horn; and the object of my invention is to so arrange the said support that the reproducer may freely swing in a horizontal plane and at the same time to permit a vertical movement of the said reproducer to follow any up-and-down movement or wabbling of the record and to always maintain the said reproducer in correct position in relation to the record; With my device it is also possible to readily and easily remove the sound-conductor, together with the reproducer, from the machine.

Other objects of invention will appear] from the detailed description, and thefeatures of novelty will be pointed out in the appended claims.

Referring to the drawings, which illustrate a specific embodiment of my invention, Fig. 1 is a side elevation of so much of a talkingmachine as is necessary to explain my invention'. Fig. 2 is a sectional View of the same on line. 2 2 of Fig. 1. Fig. 3 is a horizontal section on the line 3 3 of Fig. 1. Fig. 4 is a plan view of a portion of the sound-conducting tube. Fig. 5 is a perspective view of the supporting bracket, and Fig. 6 is a detail View of another form of joint.

A represents a portion ofthe talking-machine, which is provided in a convenient locationas, for instance, on one side-with a socket B, into which is adapted to project one end of the bracket (1, the said bracket 0 being secured in position in the socket B by means of a set-screw B. The bracket 0 at its upper or free end is bent into a substantially horizontal flange, as shown at C, the Said portion C being provided with a neck or projection D, upon which is adapted to be placed the end of the amplifying-horn E. The sound-conducting tube F carries at its one s ecification of Letters Patent.

end the reproducer G, which cooperates with the sound-record H, which may be of any suitable construction and may be driven in any convenient manner. The tube F is bent into a substantially upright portion F, said upright portion F being split at its upper end to receive and accommodate a rounded member I, having a spherically-convexed surface I, which cooperates with a corresponding concave surface D on the portion 0 of the bracket 0. At the bend of the tube are located lugs F between which extends an eyelet J, provided with a rounded stem J, projecting into a member C of the bracket C. A pivot K extends through the lugs F and the eyelet J, thus forming ahinge which permits the reproducer and the tube F'to swing in a vertical plane, the stem J serving as a pivot to permit the reproducer to swing in a hori- The curve 1 and the curve D are each struck from the center of the pivot K, so that the tube F is free to swing in avertical plane to a certain'extent without breaking the connection betweensaid tube .15 and the amplifying-horn E. It will be noticed that the diameter of the upright portion F of the tube F is smaller than the diameter of the projection D and of the amplifying-horn E, so

that there are no obstructions to the free passage of the sound from the tube through the horn to the'outside air.

' The member G 'may be provided with a reduced angular portion a, which fits into a slot 6 of the bracket 0, so that the said member G is adjustable upon said bracket 0, being held in any position by a thumb-screw a, screwing upon a screw-threaded stem cl of the member 0 as clearly shown in Fig. 5. With this construction it-is not necessary for the parts to be made as accurately as would be the case if this member C were not adjustable.

The rounded member I and the tube F might be made in one section instead of separately, as shown. I

To prevent the reproducer and the tube from dropping too far when the record is not in position or when the tube and reproducer are swung aside, I provide a stop L, which abuts against the member 0 and prevents the said tube F and reproducer from dropping too far.

In order .to secure a proper engagement of the stop L with the edge of the bracket mem ber C in their position of said stop, the said edge is given the shape of an arc of a circle,

the center of which is upon the axis of the vertical stem J. (See Fig. 3.)

When it is desired to remove the tube F and the parts attached thereto, together with the reproducer G, from the machine, the said tube F is swung at substantially right angles to the position shown in Fig. 1 and then tilted up until the upright portion F is free from the portion C, whereupon the tube F, with attached parts, may be easily lifted from the member 0 until the stem J is free from said member C and then completely removed.

When it is not desired to make the tube F, the lugs F and the stop L in one piece, I may provide a separate device, such as illustrated in Fig. 6. In this case the collar M is sprung around the tube F, near the bend thereof, and secured in position by the thumb-screw N, it being understood that the band 0 snaps around the upright portion F of the tube F. The lugs F, the stem J, with the eyelet J, and the pivot K, are secured to this band 0 and also fastened to the collar M. The stop or lug L in this case is also secured to or forms part of the collar M. This device is easily adjustable upon the tube and affords an efficient substitute when for any reason it is not convenient or desirable to make the tube F, the lugs F and stop or lug L in one piece.

It will be seen that with my device as described the reproducer is free to swing in a horizontal plane, the stem J acting as a pivot, and is also free to swing in a vertical plane upon the pivot K, while at the same time the reproducer is held upright and is prevented from wabbling, and thus losing in efiiciency.

Various modifications may be made without departing from the nature of my invention.

While the drawings show the member C adjustable vertically on bracket C, such adjustable construction is not absolutely necessary, and the member C may form a rigid part of the bracket, if desired.

Iclaim as my invention and desire to secure by Letters Patent 1. An attachment for talking-machines comprising astationar support or bracket having a spherically-concaved surface with a central aperture for the escape of the sound, a soundconductingtube provided at one end with a spherically convexed member arranged to swing adjacent to said concave surface, a reproducer at the other end of said tube, a vertical stem or spindle pivoted to a member of said bracket, said member having an edge concentric with said stem, and said tube having a stop adapted to engage said edge, and a horizontal pivot connecting said stem with said tube.

2. An attachment for talking-machines comprising a stationary member having a spherically-concaved surface and an aperture therein for the escape of the sound, a sound-conducting tube, a spherically-convexed member adjustably fitted on one end of said tube adjacent to said convexed surface, a reproduccr carried by the other end of said tube, and a universal joint for supporting said tube.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
