Specification of Letters Patent.
Patented July 241, twill.
Application filed July 22, 1915. Serial No. 41,241.
To all whom it may; concern:
Be it known that I, Hnnnn'r A. Mrnns, a citizen of the United States of America, residing at Toledo, Lucas county, Ohio, have invented new and useful SoundBoxes, of which the following is a specification.
This invention relates to vibration transmitting needles and the connections there from. t
This invention has utility when incorporated in tone producing and reproducing devices, as talklng machines.
Referring to the drawings:
Figure 1 is a fragmentary side elevation of a talking machine embodying the invention;
Fig. 2 is a View from the left of Fig. 1, with parts broken away;
Fig. 3 is a section on the line IIL-III, Fig. 2, looking in the direction of the arrow, with the valve adjusted to open partially the duct;
Fig. 4 is an enlarged fragmentary detail of a needle lever fulcrum or mounting as to the sound box;
Fig. 5 is a fragmentaryview of the lever from the left of Fig. 4, with parts broken away to show the needle mounting in the lever; and Fig. 6 is a plan view of the valve indicator.
The hollow talking machine arm or duct 1 extends to the sound box casing or housing 2 which carries the needle or stylus 3 in position as to the record 4.
In the duct 1 adjacent the housing 2 is the valve 5 readily adjustable by rotation to restrict the cross-section or effective area of the duct 1 at a point adjacent the diaphragm 6 in the sound box or housing 2. By providing this adjustment, the volume or carrying range of the machine in reproducing may be reduced, but the tones preserved as to delicacy of timber and pitch without introducing any hollow or muffling sounds.
Adherent to the diaphragm 6 by cemented rubber or sound deadening pad 7 is the lever 8. This connection of the lever 8 to the diaphragm is central as to the dia phragm.
"eliminates machine with the reproductlon tones.
The lever 8 has at its fulcrum the opposing notches 9 (shown in end view Fig. 4: and side View Fig. 5) engaged by the knife edge bearings 10, each cemented to a rubber or sound deadening pad 11, pressed into the opposing seats 12 from the housing or sound box 2.
Centrally disposed as to the fulcrum bearing 10, 10,'the lever 8 has recess 14 in which may be a short section of rubber tube or sound deadening pad 15. Forced into this recess 14 and held locked therein by this rubber 15 is the holder or quill 16 for the needle 3, which may be adjustably mounted and held in position by the set screw 17.
The mechanical sounds of the moving parts of the device are effectively checked iiriom transmission to the mechanism herein.
1e mum of resistance and leaves the needle most sensitive for vibration. The action of the rubber or resilient non-resonant means 11 is three-fold: (1) in mounting the knife edges,
(2) in taking up lost motion, and (3) in deadening transmission of mechanical noises of the apparatus. The sound deadener 15 noises from mingling The pads 11 tend to prevent any noises from the quick action. of the lever 8 getting to the sound box from this source, while the pad 7 simi larly acts between the lever 8 and the diaphragm 6.
The valved duct 1 tone volume.
What is claimed and it is desired to secure by Letters Patent is:
permits easy control of of the arms 13 extending.
1. A sound reproducer having a casing said mounting comprising provided on one side thereof with a pair of rubber means between the knife edges and 4 lugs, a '(li'aphragm for the casing, and a the lugs compressible therein as a resilient stylus lever having a mounting on said casnon-resonant mounting for resiliently hold- 10 ing and connected with the diaphragm, said ing the lever in position and insulating it 5 mounting vcomprising a pair of opposing from the casing.
