Specification of Letters Patent.

Patented Apr. 29,

Application filed April "7, 1903. Serial No. 151,454.

' which the following is a specification.

The main objects ,of my invention are to provide, in a talking machine, an improved sound box support constrained to swing in a fixed plane; to provide means for the ad- Y justment of the support to change the plane of movement thereof; to provide improved means for mounting an amplifier upon said support to move in unison therewith; to provide improved means for connecting a sound box to the support to be carried thereby and to he movable transversely of the plane of movement of the support; to provide means .of communication between the sound box and the amplifier; and to provide other improvements as will appear hereinafter.

In the accompanying drawing, Figure 1 is a side elevation of a talking machine constructed in accordance with this invention; Fig. 2 a fragmentary side elevation of the same partly in section and with parts removed; Fig. 3 a top plan view partly in 4 horizontal section of a portion of the same;

- casing 1 of the usual form, upon which is mounted the" usual turntable 2 for carrying upon its upper surface'a sound record 3. At one side of the motor casing 1 is rigidly attached a rigid supporting bracket 4 which is provided at its outer end with a vertical portion 5 to which is attached a yoke or casing 6 in which is pivoted a sound box arm 16. This yoke or casing 6 ismade adjustable on the bracket 4 by having vertical slots in the arms or sides of the yoke which register with a hole in the bracket through which passes a bolt 7 as shown in Fig. 7 of the drawings. When it is desired to change the height of the plane of movement of the sound boX arm the bolt 7 is loosened, the arm adjusted to the desired position, and the bolt then tightened to hold the yoke firmly in place upon the vertical portion 5.

A modified form of the means for adjusting the yoke in relation to the bracket- 4 is shown in Fig. 8 of the drawings. In this form the arms of the yoke 6 are provided with vertical grooves 8 in Which slidingly engage vertical ribs 9 on the upper part 5 of the bracket. The arms in this instance are also provided with longitudi-' nal slots 10 within which a bolt 11 passing through the bracket is adapted to slide; In this form it will be seen that to adjust the supporting arm of the sound box the bolt 11 is loosened and the yoke adjusted vertically by sliding the same upward or downwardupon the part 5, its motion being guided by the flanges 9 sliding in the groove 8. Upon again tightening the bolt 11 the yoke 6 is held firmly in position.

For supporting the radial sound box arm 16, the yoke 6 is provided with two horizontal vertically spaced crossbars Hand 13, which have oppositely disposed recesses forming hearings to receive the conical ends of a pair of vertical pivots 14 and 15, which are carried in a vertical socket extendin through the inner end of the solid radia sound box arm 16. These pivots are in vertical alinement, and project in opposite directions from the sound box arm, the lower one of these pivots being adjustably retained in position by a set-screw 17, and the u per one being held yieldingly in position ya spiral spring 18, which-is confined in the socket between the inner ends of the pivots. This construction permits the sound box arm to be easily removed from or replaced in its support in the yoke 6.

For supporting a sound box 22 and a horn or amplifier 27, the radial sound box arm 16 has a horizontal circular opening 19, adjacent its outer or free end, in which snugly fits'a cylindrical sound box tube or horn intake 20, integral and coaxial with the ntake end of which is an annular an or carrier of the my bra vertical sound box supporting plate or flange 21. Upon the flange 21 and in communication with the horn intake is pivoted the sound box proper 22, by means of a horizontal screw 23, passing loosely through a lateral extension of the back plate sound box, and'threaded into the flange. The sound box is movable in a vertical plane about its pivot and across the mouth of the horn intake, and is pro vided as usual with a stylus bar 24 and a diaphragm 25.

A sound amplifier or horn 27, or other sound conducting means, has its inner end carried by and communicating with the out let end of the horn intake tube 20, and is also carried, intermediate of itsends, by a horizontal rod or support 26, which contacts against the under side of the horn, and one end of which is rigidly attached to the sound box arm at any suitable point to give the desired inclination .to the horn or sound conveyer.

The rear or carrier plate of the sound box may be provided with a short tube or flange 29, surrounding the opening between the sound box and the horn intake and projecting slightly into the horn intake, thereby directing the sound waves from the sound box into the intake, and limiting the vertical movement of the sound box with respect to its supporting flange 21 and sound box arm 16. This short tube 2 is not essential, but is considered to be a desirable feature of the construction.

in the operation of this machine, the plane of movement of the sound box supporting arm 16 may be adjusted vertically by adjusting the yoke 6 by means of the bolt 11 to bring the sound box 22 intothe proper plane to coiiperate with the record 3, and in this position the sound box is per mitted to yield sutiicicntly in either direction vertically about its pivot 23, to follow any slight irregularities in the record, or to compensate for any inaccuracies in the mounting of the turn-table.

This invention is not limited in its application to the particular cpnstruction herein illustrated, as various changes might be made in the construction shown without de parting from the spirit of this invention, or the scope of the appended claims.
