FREDERICK JAMES nlvirson, or SYDNEY, new scorn warns, AUSTRALIA.
Application filed January 10, 1914, Serial No. 811,455. Renewed October 10, 1919.
To all whom it may concern Be it known that I, Fnnnnnion Janus EMPSON, a subject of the King of Great Britain, residing at Sydney, New South Vales, Australia, have invented new and useful Improvements in T alking-Machines, of which the following is a specification.
My present invention relates to improvements in talking machines and the like and more particularly to a sound controller therefor. The advantages of my improvements will be apparent to those skilled in the art from an understanding of the following specification in connection with the annexed drawings which diagrammatically illustrate only some of the specific embodiments Which my invention is adapted to take.
In these drawings, Figure 1 shows one form of my invention arranged to control the sound passage in the tubular connection 'which operatively connects the tone-arm with the horn of a talking machine, the valve parts'being shown just closed. In the remainingfigures, I have not repeated the ph'ono raph parts such as the tone-arm and horn, Tut for simplicity show merely the valve parts; Continuing with a brief description of the drawings, Fig. 2 illustrates the valve parts of Fig. 1 still further seated or adjusted relative to each other; Figs. 3
and 5 show two modifications of the valve parts illustrated in their just seated posi tion; and Figs. 4 and 6 respectively illustrate the valve parts of Figs. 3 and 5 still further seated on each other.
I will now describe the specific devices of the drawings,- reserving it to the claims to point out the novel features and to define the scope of the invention, it being understood that the claims will be given the due range of equivalents to which they may be entitled in view of the art.
1 is th'ebase portion of the tone-arm of a phonograph having a swiveling connection at 2 with the tubular coupling 3 between which and the small end of the horn 4 is clamped the flanged base portion 5 of the soft, flexible rubber throat 6 by means of the screws 7. 8 is aplug valve on the valve stem 18 adapted to be given axial adjustment from' a position well away from the circular lip ormouth 9 of the throat, wherein the loudest-or double forte playing effect is obtained, through intermediate positions to one wherein the valve is just in contact Specification of Letters Patent.
TALKING-MACHINE.
Patented May 18, 1920.
Serial No. 329,891.
with said lip, and thence to positions beyond with a gradual diminuendo from said double forte effect to double pianissimo; and vice versa as the valve is withdrawn or operated in the reverse direction.
The actual means is not illustrated by which the listener can adjust the valve to modulate the tones sympathetically at will to conform with the constantly changing e:; pression effects proper to the selection being played, because this means is not the subject matter of my present patent.
The throat member of Figs. 1 and 2 should be so made that its lip 9 is very thin and so that its wall gradually thickens from said lip to an imaginary circumferential line 10, between which and the base of the throat the material is so thick that it is relatively non transmitting to the sound-waves. The result is that when the valve is just seated on the lip 9, the tone is not abruptly diminished as compared with the immediately adjacent open position of the valve, because the sound can still pass by and through said lip and, to a diminished extent, through the taperthickness zone of the throat between this lip and the part 10 beyond which it is assumed the throat wall is so thick that it is substantially non-transmitting to sound.
It follows that when the plug in Fig. 1 is still further adjusted toward the throat, it pushes against the thin lip and thickens it, with resulting diminution of tone by the mere fact of said thickening. Also, the plug then begins to enter the mouth of the throat and, as in Fig. 2, can be caused to contact with and cover the sound transmitting Zone of the throat to an increasing extent up to the line 10. The valve prevents the sound from passing through this soundtransmitting zone to the extent that it covers it, and since this zone gradually thickens to a condition of substantial non-transmissi on to the sou nd waves, it follows that the entering valve causes a delicate diminuendo on entering, and a delicate crescendo on being withdrawn. Also, there is no sudden break or marked contrast at the moment the valve either closes or leaves the lip of the throat.
Fig. 3 differs merely in showing, compared with Fig. 1, a longer sound-transmiting Zone between the lip 9 and the nonsound-transmitting portion 10. The result is that this portion is so flimsy that it folds back on itself, as shown in Fig. 4:, carried on the advancing valve, but the general cf" feet is the same that the plug can be adjusted at will to cover the sound-transmitting zone to any desired extent to produce corresponding differences in tone in the playing of the instrument.
Fig. 5 merely differs in forming the throat of Figs. 1 or 3 with an initially inwardly directed lip 9 to give it all the more natural tendency to fold inwardly described.-
lVhere the valve slides in the throat as in Figs. 1 and 2, it may with advantage be made of a smooth surfaced material like hard rubber, but where it does not, as in the remaining figures, it may be made of soft, elastic rubber.
lVith the device of my present invention, a great range of expression effects is obtainable from sharp contrasts obtained by quick movement of the valve, to smooth crescendo and diminuendos.
