To all whom it may concern:
Be it known that I, CHARLIE America, residing at Bay City, in the county of Bay and State of Michigan, have invented certain new and useful Improvements in Sound-Control Mechanisms for Talkingl\lachines, of which the following isa speci- This invention relates to sound control mechanisms for talking machines.
One object of the invention is to produce a simple and economical device for regulating and controlling the'volume of sound emitted from the tone horn of a talking machine.
Another object is to provide a device of this character that can be controlled during playing, by the operator at any distance from the machine. a
A further object resides in the provision of a tone horn of a talking machine with a valve or muflier for controlling the volume of sound emitted therefrom and provided with means for operating the same.
lVith the above and other objects in view,
the present invention consists in the'combination and arrangement of parts hereinafter 'more fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claim, it being understood that changes ma be made in the form, size, proportion an minor details without departing from the spirit or sacrificing any of the advantages of the invention.
In the drawings z- Figure 1 is a sectional view ofa cabinet talking machine with the device positioned therein.
Fig. 2 is an enlarged plan view of the device.
Fig. 3 is an enlarged side elevation of the device.
In the drawings 1 indicates a cabinet talking machine of the type now in general use. The usual compartment 2 is provided in said cabinet, through which the tone horn 3 eX- tends. The tone horn is provided intermediate its length with a valve or mufiler 4 rigidly secured to an arbor 5 mounted to oscillate in suitable bearings formed in the tone horn. The arbor 5 is oscillated through the instrumentality of an arm 6 secured to J. Bobs-- anew, a citizen of the United States of the arbor5 ata point located eXteriorly of the horn 3.
NVithin the compartment 2 is located aflat bar 7 slidably mounted on a bracket 8 fas- Patented Feb.18, 1919.
tened to the'interior wall of the cabinet 1. 1
One end of said bar 7 is provided with a series of notches 9 ada ted to engage a pin 10 fixed in the side of t is cabinet 1 adjacent the bracket 8.
A. lever 12: is pivoted to the side of the cabinet 1 by means of the pin 11,.bu't'spaced therefrom, and-one end of which is pivoted to the end of the bar 7 by means of the pivot pin 13. The lever 12'is spaced'fr'om the bar 7 by means of said pivot pin 13. The opposite end of the lever 12 is pivoted to a second lever 14 as shown at 15, and this second lever 14 has its opposite end pivoted to the arm 6,
by means of the pin .16. v
A spring 17 has one end attached to a pin 16, while its opposite end is attached to the side of the cabinet 1. This spring has a tendency to hold the valve or mufiler 4 in its closed position.
' The bar 7 is adapted to be moved by means of a cord or rope 18 attached to the free end of the bar and terminating in a tassel 18 which extends through an aperwhich cord is adapted to be fastened to the end ofthe cord or rope 18 by a snap fastener adapted to hook into a ring concealed in the tassel 18".
From the foregoing it will be apparent that it is only necessary to pull outwardly on the rope or cord 18 to open the valve or mutiler to any' degree desired, thus by pulling outwardly and releasing the cord 20, which will open and close the mufiler or valve 4, (through instrumentality of the bar 7 lever 12 and 14 and arm 6) the operator can. enunciate the music as the record is being played. If a certain volume of tone is desired, the operator by elevating the auxiliary cord 20, (as shown in dotted lines in Fig. 3) hooks one of the notches 9 in the bar 7 over the pin 10, thus holding the valve or muffler 4 in any desired position, from which it can be disengaged by pulling outwardly on the string 20.
By providing the auxiliary cord 20 it will he appareni'; thatbhe operator of the talking machine may sit any desireddistanee or angle in front of same, and control the volume of Sound emitted from Hie tone horn.
\Vhat I claim, is:
In a talking machine provided Wii-h a tone modifier normally held closed, means for operating such modifier from a distant point and holding the same in an adjusted position. consisting of a member mounted to reemmas eeivo hofh a pivotal and a longitudinal movement and having a series of teeth in its lengbh, an element to oo-aet with the teeth to hohl the member in the adjusted position, and a flexible operating member extending from. the pivotal and longimdinally movable member to admit of the two-fold movementheing imparted thereto from any required point distant from the machine.
in testimony whereof I aflix my signature.
CHARLIE J. BUUSFIELD.
