' 'PHONOGRAPH.

Application filed April 15,

lb oll zelhom ttmoy concern:

' Be :known that LJoHN F, Orr, a citizen of the United States, and a resident of Orange, in thecounty of Essex and State of New d'ersey, have invented certain new and useful Improvements in Phonographs, of

' which the following is a description.

My invention relates to means adapted to cooperate with the feed screw of a phonograph for imparting a p1'ogressive movement to the sound boxlcarriage and coming upon records having either one-hundred or two hundred threads per inch.

My invention relates more particularly to feedingmechanism of the general type shown and broadly claimed in an application filed by me on J anuaryr 20, 1908, Serial No. 411,834, and has for its object the provision ofzimproved means for locking the worm against rotation, for unlocking the same and transmitting the rotation thereof to .a gear which cooperates wlth a rack or abutment for feeding the carriage,

for shifting or sliding the worm gear and for locking said shifting means, all as will be more particularly set forth and claimed.

Reference is hereby made to the accompanying drawing of which- Figure l'is a plan view of a portion of a v phonograph showing my invention applied thereto, and Fig. 2 is a section on line 2-2 of Fig. 1.

The phonograph shown 18 of ordinary form and comprises a base or body 1, a main shaft 2 journaled therein and provided with a feed screw 3 of fine pitch, such as one-hundred threads per inch, and a drive pulley 4. The sound box carriage 5 slides upon the back rod 6 and there is fixed rack or abutment '7 carried by aframe 8 which is secured to the rod (3. Secured to the carriage 5 by the screws 9, and extending forwardly therefrom, is an arm 10. This arm is provided with a socket 11, and within the same and secured by the set screw 12 is a forwardly extending pin 13 which carries at its end a locking disk 1i having a. stud 15. "here is a, worm gear 16 journaled on said pin 13 and engaging the thread of the feed screw 3. This gear is slidablc along the pin 13. There Specification of Letters Patent.

{Jare anumber of sockets 1T formed-in the face of the worm gear 16, each ofwluch is adapted to receive the stud 15 of the disk 1 1 for locking these parts together when the gear 16 is in its extreme forward position. Integral with said gear is abevel gear 18 l which is adapted to engage a similar gear 19 i when the gear 10 is in its extreme rearward l position. In this position the disk 1d and gear 16 are out of locking relation and the gear 18 rotates the gear 19. Thelast named gear is journaled on a vertical pin 20, the

lower end of which is provided with a disk 21 which supports the gear 19 and there is a pin 22 extending downward from said disk into engagement with a groove 23, formed on the hub of the gear 16. The upper end of the pin 20 is provided with a head 24, in the lower surface ofwhich are formed a number of notches or depressions 25 adapted to receive the upper end of a locking bolt 26 situated within a socket formed in the arm 10 and pressed upward by a spring 27 There is a sleeve 28 rotatable upon the pin 13 and formed with a bevel gear 29 which engages the gear 19, and with a spur gear 30 which engages the rack 7. The head 24 is provided with indicating numerals or indicia 31 which cooperate with a pointer 32 secured to the arm 10 for designating the rate of feed of the sound box carriage.

lVhen the parts are in the position shown in Fig. 2, the worm gear 16 is locked to the disk 14, being held in locked position by the pin- 20 and stud 23 carried thereby. In this position the worm gear 16 is incapable of rotatioh and therefore acts as an ordinary feed nut to feed the carriage at a rate suitable for operating upon records having one-hundred threads to the inch, and'the indicating nuvinera-ls 100 upon the head 24% are opposite the pointer 82. i/Vhen the head 24 and pin 20 are rotated through an angle of 180 the worm gear 16 is unlocked from the disk 1% and the bevel gearv 18 brought into mesh with the gear- 19. l/Vith the parts in this position the gear 16 is rotated by the feed screw 3 and imparts a rotation in the op )0- site direction to the spur gear 30 and the fat-- ter by reason of its engagement with the rack 7, imparts a forward progressive movement to the sound box carriage at a rate suitable for opera'ting upon records having two-hunilt) - sa-itl leetl screw, rotary means engagr 'nu-nt aml s'aiil screw. means sii iporting the with saiil tirst nametl rotary n'ieans, substantired threads per inch, St1i(l rate of speet being designated by the numerals 2G0 whicl are then opposite the pointer Having now described my invention, what I claim is:
