PHONOGRAPH-REPRODUCER.

Specication of Letters Patent.

Patented Feb. 9, 1915.

To ally whom it may concern.'

Beit 'known' that I, FRANK L. DYER, a citizenof the United States, and a resident of Montclair, in the county of Essex and State of'New Jersey, have made a certain new and useful Invention in Phonograph- Reproducers, of which the following is a description.

My invention relates to phonograph reprodueers, and my object is to provide an effective andnovel means for mounting a pair-.of reproducing styli connected to the diaphragm of the reproducer in such a manner that either may be simply and effectively adjusted into `position to coperate' with a" record groove of adistinctive character, so that, for example, a lstylus adapted to cooperate with a'- record having 100 threads per inch anda stylus adapted to coperate with"y a record having 200 threads per inch may be' mounted in the same reproducer.

" In carrying out my invention, I preferably mount the stylion one end of a pivotally supported -stylus lever, the styli being disposed-fon opposite sides of the centerline 'ofsaid' lever, and provide means for swinging said lever through an arc about an axis approximately parallel to the center line of saidlevier for the purpose of lowering either stylus, into ,operative position, while raising theoth-'en-,out 'ofsuch position.

. Otherf-.objects of my invention reside in the`v construction of parts and combinations of elements ias. described in the following specific-ation' and particularly pointed out in the appended lclaims.

Attention lis hereby directed to the accompanyingl drawings forming part -of .this specification, in which the same reference charactersareused throughout to denote corresponding parts, and in which- Figure. 1 represents a 'vertical' section through a--reproducer embodying my inven tion, certainl parts thereof being shown in elevation; :Fig.v-2 is a bottom plan view of the sameand Figf is a fragmentary end view. of the reproducer shownin Fig. 1 lookingin'` theydirection of thel varrow shown in connection therewith. 1

Referring to the drawings, thediaphragm 1 is horizontally mounted in the reproducer body or sound box ,2, `being fheld between rings 3 and secured in lace by the clamping f ring 4,which isthrea ed within depending annular flange 5 of the reproducer body in the Vwell known manner. The weight or supporting member 6 is pivotally supported by the horizontal pin 7 which is mounted in vertical -block 8 which is formed integrally with or is secured to the substantially vertical pin 9 which is threaded within or is otherwise rotatably secured within the member 10. The member 10 has formed integrally therewith or secured thereto the horizontal pin 11 which is pivotally mounted in the clamping ring 4 and the flange 5 of the reproducer. The member 10 is thus secured inside the clamping ring 4, the outer end of pin 11 extending into a cutaway portion 12 of the depending flange 5 of the reproducer body. The lever` or manipulative member 13 is secured to this outer end of pin l1 and extends up through recess 12 to form a handle by which the pin 11 may be rotated' through a limited arc, the walls 14 of the recess 12 forming stopping means for limiting such motion. Any suitable means may be provided for retaining the pin 11 and connected parts in any adjusted position. I have shown the spiral spring 15 encirclin the in 11 and confined between the'borc o the dlamping ringe andthe adjacent surface of member 1() for frictionally holding the j 16 bearing upon the upper surface of member 6 to force the same downwardly, The pin 17 is provided extending from the surface of supporting member 6 at a point diametrically opposite from the pivotal mounting of said member, said pin coperating with a stirrup 18 depending from the lower surface of flange 5 of the reproducer body to limit the downward and lateral movement of supporting member 6 in the well known manner. Stylus arm or lever 19 is pivotally supported on horizontal pin 20, which is held by lugs or ears 2l. These ears 21 may be formed integral with the lower surface of weight 6, or they may be integral with a member supported by said weight 6 and having rotative movement relative thereto to afford greater lateral movement to the stylus or Styli carried by the stylus lever 19. Iha've shown such a mounting in the drawings, in which lugs 21 are integral with a member having a portion 22 mounted ord of a diferent inthe lowersurface of supporter f3 and extending b'ackwvardly apir a horizontal direction from al.. the pin 23 rising from the end nl. oti'set portion 22 and having a head ing upon the upper surface of weight upported rotatably in said member 6 24 re 5 fi in any other convenient manner to form a substantially vertical pivot in the said member. T he lever 19j is connected by the link to thc center of diaphragm 1 in the Well .lin/mn manner. The stylus lever 19 is farniedat its end opposite from that to Y which the link 25 is connected with a forked Portion, the prongs of the fork extending on opposite sides of the center line of lever l5?, and each carrying a stylus 26. One of these stvli is adapted to co-act with a record of a certain character as for example, a record having 100 threads per inch, while the other stylus is adapted to co-act with a. reccharacter, as for example, one having 200 threads per inch. These styli are so formed and are so positioned as to properly co-act with their appropriate records When stylus lever 19 is swung through a certain predetermined angle about the pin llas an axis.

In Fig. 3 one stylus 26 is shown in operative position for trackinga record having 100 threads per inch, While the other stylus 26, which is adapted to track a 200 thread record, is shown elevated out of operative position.

I t is to be understood that While I have described the preferred form of my invention, I am not necessarily' limited to the exact construction of parts disclosed, but may modify the same within the terms of the appended claims.
