DAMPER FOR TALKINGP'WIACHINES- Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed January 6, 1906- Serlal No. 294.9%.

To all whom it may concern.-

Be it known that I, JOHN C. SoHLEIoHER, a citizen of the United States, and a resident of Mount Vernon, in the count of Westohester and State of New York, ave invented certain new and useful Improvements in Dampers for Talking-Machines, of which the following is a specification.

The subject of this invention is a reproducer damper for talking 7 machines, and while disclosed herein as being associated with the type of machine wherein the record is in the form of a rotative horizontal disk said invention is also well adapted for machines using a cylinder-record.

It has been found in practice that the presence of dust or other foreign matter or abnormal irregularities on the record, particularly of the disk form, causes vibrations of the stylus-arm and the stylus mounted therein, which are magnified at the reproducing-diaphragm and produce harsh and discordant sounds. In addition it is desirable at times to modify and soften the sound thus reproduced.

My invention is designed to obviate th former defects in reproducersand also to equip the reproducer so that its tones and sounds shall be modified.

While the invention is disclosed in the accompanying drawings and set forth in the subsequent detailed description as being in the form of an attachment for reproducers, the improved device can be so embodied in connection with the reproduoer as to constitute a permanent part thereof.

There are other important features connected with the invention, which, besides those alluded to, are clearly hereinafter explained.

In the accompanying drawings, forming part of this speclfication, Figure l is a side view showing a familiar form of reproducer embod g my invention. Fi 2 is a somewhat slmilar view, the damper eing applied. Fig. 3 is a sectional view disclosin' a modification of Figs. 1 and 2. Fig. 4 1s a detail view of a modification, showmg the springarm provided with a pivoted dog.

Referring more articularly to Figs. 1 and 2, A represents t e ring or sleeve 'of the sounding-box, B the diaphragm thereof, 0

the stylus, and Of the stylus-arm in which the stylus is mounted, all of whichparts are of the ordinar well-known construction, and

therefore nee not be further described. Un-

the ring or shell A of the sounding-box,

whereby a lateral turn engages the ends in position. v This leaf-spring D carries a spring member or arm E, which may or may not have a cushion e. will suffice for the purpose. The bow of the leaf-spring admits of an adjusting-screw F being tapped theretbrough, so as to bear on the free end of the spring member or arm and force it toward the stylus-arm to restrict its vibrations and the vibrations of its stylus.

In Fig. 3 I have illustrated the construction in which the bow leaf-spring E is indi-- cated and the spring-adjusting screw F is represented at one side of thee ring-arm G. The diaphragm oint or nee e is referred A bit of tubular rubber to by C.- It wil be observed in this construction, that the free end of the spring E equipped with the same damper material prev1ously alluded to.

In Fig. 4 I have shown a construction in which a sprin arm G, similar to the arm E,

on the free en of which a dog H is pivotally mounted, so as to ada t it to be turned between the end of sai spring-arm and the stylus-arm and forced toward said stylus? arm by screwing in the adjusting-screwto" thereby dampen the sound, or turned out of the wa so that the end of the spring-arm will 0 y be inter osed between said parts and forced towar the stylus-arm by screw- I ing in the adjusting-screw.

I do not wish to be understood as limiting myself to the precise construction and arrangement of arts shown, but reserve the my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A dampening device for talking-machines, embodying an arched bridge, a spring-arm one end being free and a dog pivoted on the free end of said spring-arm, sub stantially as described.

2. A dampening device for talking-ma- .right to all mo ifications within the scope of chines, embodying an arched bridge, a

spring-arm one-end being free, a dog pivoted on the free endof said s ring-arm and means carried by said arched ridge for forcing said spring-arm inwardly, substantially as described.

3. A dampening device for chines, embodying a spring-arm one end .adapted to be secured -to the sounding-box thereof and the other end being free and a dog pivoted on the free end of said springarm, substantially as described.

4. A dampening device for talking-machines, embodying a spring-arm one end adapted to be-secured to the sounding-box thereof and the other end being free, a dog pivoted on the free end of said spring-arm, and means for forcing said spring-arm inwardly, substantially as described.

5. In a reproducer for talking-machines, the combination of the sounding-box and a dampening device embodying an arched bridge mounted on said sounding-box, a spring-arm mounted on said sounding-box one end being free and projecting over the stylus-arm, and a dog pivoted on the free end of said spring-arm, substantially as described.

6. In a reproducer for talking-machines, the combination of the sounding-box and a dampening device embodying an arched bridge 'mounted on said sounding-box, a

spring-arm mounted on said sounding-box.

one end being free and projecting over the stylus-arm, a dog pivoted on the free end of said spring-arm, and means for forcing said spring-arm toward said stylus-arm, substantially as described.

7. In a reproducer for talking-machines, the combination of the sounding-box having notches and a dampening device embodying an arched bridge the ends adapted to be inserted into said notches and turned to engage said sounding-box to removably secure it thereon, a spring-arm removably secured on said sounding-box onev end bemg free and projecting over the stylus-arm and means adjustably mounted in said arched bridge for forcing said spring toward the stylus-arm,

substantially as described.

8. In a reproducer for talkingmachines, the combination of the soundingox having notches and a dampening device embodying an arched spring-bridge the ends adapted to talking mabe inserted into said notches and turned to engage said sounding-box to removably secure it thereon, a spring-arm removably secured on said sounding-box one end being free and projecting 0VeI the stylus-arm-and means adjustably mounted-in said arched s ring-bridge for forcing said spring toward t 1e stylusarm, substantially as described.

9. In a reproducer for talking-machines, the combinationof the sounding-box having a notched flange and a dampening device embodying an arched bridge the ends adapted to be inserted into the notches in the flange of the sounding-box and turned to engage said flange to secure'it, a spring-arm one end secured to the sounding-box and the free end the combinatlon of the sounding-box having a notched flange and a dampening device embodying an arched bridge the ends adapted to be inserted into the notches in the flange of the sounding-box and turned to engage said flange to secure it, a spring-arm one end secured to the sounding-box and the free end projecting over the stylus-arm a piece of dampening material on the free end of said spring arm, and means for forcing said spring-arm toward said stylus-arm, substantially as described.

11'. In a reprbducer for talking-machines, the combination of the sounding-box having a notched flange and a dampening device embodying an arched bridge the ends adapted to be inserted into the notches in the flange of the sounding-box and turned to engage said flange to secure it, a spring-arm one end secured to the sounding-box and the free end projecting over the stylus-arm, 'a iece of dampening material pivoted on the ee end of said spring-arm, and means for forcing said spring-arm toward said stylus-arm, substan tially as described.
