PHONOGRAPH-REPBODUCER.

Specification of Letters Patent.

Patented Nov. 24, 1908.

Application filed March 26, 1908. Serial No, 423,383.

To all whom it may concern:

Be it known thatI, PETER WEBER, a citizen of the United States, and a resident of Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Phonograph Reproducers, of which the following is a description.

My invention relates to phonograph reproducers and has for its ob]ect the production of a reproducer having two Styluses, preferably carried by levers which are pivoted to floating weight and said styluses being adafpted to operate u on phonograph records 0 different pitch, or instance, one stylus may be suitable for records having one-hundred turns or threads per inch and the other stylus suitable for records havin two-hundred threads per inch, both of said Styluses, however, being connected to and adapted to impart vibrations to the same diaphragm.

In order that the invention may be more fully understood, reference is made to the accompanying drawing of which- Figure 1 is a bottom plan view of a phonograph reproducer constructed in accordance with my invention; Fig. 2 is a section on line 22 of Fig. 1; and Fig. 3 is a detail view, partly in section, showing the index finger for indicating which ofthe styluses is in operative position.

The reproducer shown comprises a body 1 within which the diaphragm is secured by the clamping rings 3, 4 and 5 represent ing metallic rings or gaskets, and 6 and 7 paper washers. The floating weight 8 is pivoted at 9 to the lug 10 which is secured to the lower end of the screw 11, threaded in the body 1. The floating weight 8 is formed with a central opening 12 and recess 13 within which is situated the stylus carrying flanged sleeve or bushing 14. The CXtQn rior of said bushing is formed with a. pair of flat surfaces 15, and a plate 16, having a central opening adapted to fit upon the bushing is placed thereon, after which a spring washer or dished spring late 17 is placed upon the bushing and a e amping nut 18 is screwed upon the end thereof, so as to secure the bushing in position. The bushing is rotatable with respect to the weight 8, being held in position by frictional engagement therewith and its an ular movement in each direction is limited y the shoulders 19 and 20 formed on said plate 16 in position to engage a stop which IS in the form of a screw 21 threaded-in the wei ht 8. Depending from the lower surface of the bushing 14 are pairs of lugs 22 and 23 respectively, to which are pivoted the stylus levers 24 and 25. The outer end of the lever 24 is provided with a stylus 26 of proper form and size for operating upon a sound record having two hundred threads per inch, and the outer end of the lever 25 is provided with a stylus 27 suitable for operating upon a sound record having one-hundred threads per inch. The inner end of the lever 25 is forked and receives the reduced end of the lever 24, and there is an eye or openin 28 formed in each of said levers through w iich passes the lower end of a link 29. The up per end of said link passes through, the bottom of a'cup 30 which is secured to the center of the diaphragm, and a ball 31 is secured to or formed u on the end of the link so as to form with sald cup a swivel or ball and socket joint, which permits the rotation of the bushing 14 without affecting the con neetion of the stylus levers with the diaphragm.

Thereis an index finger or pointer 32 secured to the lower surface of the bushing 14.

by screws 33, the point of which extends in proximity to the surface of the floating weight 8, and upon the latter are placed indicating figures 34:, whereby the pointer 32 designates which of the styluses is in proper position for operating upon a record surface; thus, if the pointer is o posite the figures 100, as shown in Fig. 1, tl ie stylus 27 is in proper position for operating on record a, and when the sleeve 14 is rotated through an angle of 180 the stylus 26 will be in operative position and the pointer 32 will be opposite the figures 200.

Having now described my invention, what I claim is:

1. In a phonograph reproducer, the combination of the body, a floatin weight pivoted to said body and a pair 0 Styluses car- ,ried by said floating weight, each of which is movable independently of said weight into and out of operative position with respect to the record surface, substantially as set forth.

. 2. In a honograph reproducer, the combination o' the diaphragm, floating weight and connected to said diaphragm, each of said Styluses having an an ular movement independently of said Weig t into and out of operative position with respect to the rec- 0rd surface, substantially as set forth.

3. In a phonograph reproducer, the combination with the body, floating weight and stylus carrier pivoted to said floating weight, of a pair of Styluses carried thereby and movable into and out of operative position with respect to the record surface, substantially as set forth.

4. In a phonograph reproducer, the combination with the diaphragm and floating weight, of a pair of stylus levers connecte to said diaphragm and pivoted upon a support rotatable upon said floating weight,

substantially as set forth.

5. In a phonograph reproducer, the combination of a body, floating weight, a support mounted on said floatin weight, stylus levers connected to said diap ragm and pivoted to said support, said support being n1ovable with respect to said floating weight, whereby either of said Styluses may be brought into and out of operative position with respect to the record surface, substantially as set forth.

6. In a phonograph reproducer, the combination of the floating weight, the spring washer 17, the flanged bushing passing through said weight, means for compressing said spring washer and clamping said bushing and weight together, a pair of stylus levers pivoted to said bushing and a link connected to said levers and passing through the bore of said bushing, substantially as set forth.

7. In a phono raph reproducer, the combination of the diaphragm, floating weight, bushing 14, stylus levers pivoted thereto, a link 29 passing through the bore of said bushing, and a swivel connection between said link and said diaphragm, substantially as set forth.

8. In a phonograph reproducer, the combination of the dia hragm, the cup 30 secured thereto, the link 29 having a ball 31 within said. cup, a stylus lever connected to the other endof the said link, a support for said stylus lever, and a floating weight, said support being rotatable with respect to the floating weight, substantially as set forth.

.9. In a phono raph reproducer, the combination with tie body, diaphragm, and floating Weight, of a pair of styluses of different diameters carried by said weight and connected to said diaphragm, substantially as set forth.

10. In a phonograph reproducor, the combination with the body, diaphragm, and floating weight, of a pair of styluses of different diameters carried by said weight and connected to said diaphragm, and means for imparting an angular movement to the styluses to bring either one into and out of operative position with respect to the record surface, substantially asset forth.

11. In a phonograph reproducer, the combination of the body, diaphragm and floating weight, of a stylus carrier pivoted to said weight on an axis substantially in alinement with the center of the diaphragm, substantially as set forth.

12. In a phonograph reproducer, the combination of the body, diaphragm and floating weight, of a sleeve carried by and rotatable with respect tosaid weight, a stylus lever pivoted to said sleeve and a link passing through said sleeve and connectin said diaphragm andsaid stylus lever, substantial y as set forth.

This specification signed and witnessed this 24 day of March 1908.
