To all whom it may concern:

Be it known that I, PETER WEBER, a ci ti zen of the United, States, and a resident of Orange,-,jn-the county of Essex and State of New Jersey, have invented certain'new and useful Im rovements in Phonographs, of which the Following is a description.

My invention relates to phonographs of the type wherein'the sound box is carried on atraveling'carri'age to which a progressive movement is imparted by means of a rotatmg feed screw, so that the reproducer orreco'rderstylus 'traces a spiral path with respect to the record surface. It has been the to, rovidea feed screw of fine pitch which wil advance the traveling carriagea distance of one one hundredth of an inch for each revolution of the mandrel. More recently, howevcliy; it has been found possible to manufacture-a sound-record in which the recordfiroo ve has two hundred turns or threads to t e inch, so

that it is desirable to provide a phonogra h' in which the feed of the carriage will be suit of'this description. In view of the fact, "however, that there are already thousands of phonographs in use in w'h1ch the feed screw advances the carriage one one-hundredth of an inch per mandrel revolution, and a vast number of records are also in use having a pitch of one one-hundredth of an inch, it is desirable to provide means which may readil be applied to such phonographs where y the feed screw may be driven at one-half the speed at which it has been heretofore driven-,such means also permittin the drivin speed, so t at the phonograph can be used interchangeably with sound records having either one hundred or two hundred threads per inch, and my'invention has for its object the provision of interchangeable means of this character which may be readily applied to a phonograph and in which, when so ap plied; the parts may be readily shifted with respect to each other; so as to drive the feed screw-at the desired rate of speed. Reference .is hereby made to the accom panying drawings, of whiclis Figure 1 is a lan view showing a portion of a phonograp constructed inaccordance of'the same, and

-of the feed screw at its usua of a well-known form and comprises-a base 1, formed with anupright2 havinga center 3 which supports one end of the mandrel shaft 4, which carries the mandrel5. A. drive pulley 5 is secured to the shaft 4, and is adapted to receive the drivin belt from the motor. A drive gear 6 is xed to the ,shaft 4. Parallel tdthe mandrel shaft 4 and" in the rear thereof is the-feed screw shaft 7, one end of which is sup orted upon the pivot pin or center 8, carrie by the upright 2. A gear 9 is fixed to the shaft 7 and tably mounted-on a movable pin 11 which is supported in a boss formed on the upri ht 2. The gear '10, when in the position 0 Fig. 1, is in 'engagem.e'ntwith the gears 6 and 9, and the sha shaft 4 through thegears 6, 10 and 9 which are roportioned for driving'the'snatt i and fe mg the'sound- .box' carriage 21'Rat the proper speed for g'perating-upon asound record, t e pitch o which s onesone-hundredth of an i'nch.- The pin 11 is; provided with a knob or head 12 ,for moving the same longitudinally therebi from engagement wit the gears 6 an '9, A set screw 22 may be provided for holding the pin 11 in any desiredpo'sition;

In order that the shaft Z may be driven at a speed suitable for operating upon a record having two hundred threads per inch, -I provide a frame or en port 1 3 which is mounted upon; the end" o the .p1n 8 WlHCh 'roj ects beyond the upright 2, i said frame eing angularly adjustable upon said pin and adapted to be clamped in'a .fixed os 1- tion bymeans of a set screw 14. I118 frame carries agear'train' composed. of spur gears 15,16, 17 and 18. The frame 13 may be moved in a direction parallel with the axis of'the shaft 7 so as to bring the gear 18 into and out of engagement withthe gear i). When the gear 10 is in the position of Fig. 1 for driving the shaft'T at a speed for 0 9erating upon records having 'one hun red threads tothe inch, the frame 13 will preferabl occupy the position shown in Flgs. 1 an 2, although, of course, it could occupy a position in which the gear l8 engages the ear 9, provided the gear 15,1s not 1n engageeve the ,,wou d be is adapted to bedri'ven by a gear 10 rotat 7 isldriven from the removing the car 10 mentqwith thegear 6; In thiscase, how-Q ars carried by the. frame. 1 3 dgriven as idlers, thusintroducing 1 Lil unnecessary friction. When the frame 13 is adjusted upon the pin 8 from the position shown in full lines, Fig. 2, to the position in dicated in dotted lines, the gear 15 will be brought into engagement with the drivin gear 6, and thegear having been moved out of engagement therewith, the shaft? will be driven through the gear train 6, 15, 16, 17, 18 and ,9, and these gears are so proportioned that the speed of the shaft 7 will be suitable for feeding the sound box carriage with respect to a sound. record having two hundred threads per inch. All that is necessary to-convert the machine into one suitable for a record of one hundred threads to the inch is to move the frame lfilinto the osition shown in the drawing, securing it y the set screw 14, and then move the gear 10 into the osition shown, which operation can be readi y understood and performed by the ordinary user of a phonograph. The frame 13 is preferably provided with a projecting foot 19 which is adapted to restupon the upper edge of the upright 2 when the frame 13 is in the position shown in dotted lines, Fig. 2, thereby supporting the frame 13 in its operative position.

The honograph shown in Figs. 3 and 4 is simi ar in its general features to that of Figs. 1 and 2. The guide rod 20- in the machine of Figs. 3 and 4 is situated above the shaft 7 and upon its outer end may be secured the frame 13, which is similar to the frame 13 and which carries the gear train 15, 16, 17 and 18 adapted to operatively connect the gears 6 and 9 carried by the shafts 4 and 7. The frame 13 has a foot 19 adapted to rest upon the upright 2, and a set screw 14 is provided for holding the frame 13 in its inoperative position as shown in full lines, Fig}. In this position the gear 18 will necessarily be out of engage ment with the gear 9, and it is therefore unnecessary to move the frame 13 in a direction parallel to the axis of the shaft 7'. In all other respects the device of Figs. 3 and 4 is the same as that of Figs. land 2.

It will be noted that in my invention the frame of an existing type of phonograph is made use of unchanged, the only changes which must be made to the same to adapt the machine to operate on one hundred and two hundred thread records interchangeably, being the substitution of the sliding stud 11 for the fixed stud for carrying the interme-- diate gear 10 of the existing gear train between the mandrel shaft and the feed screw shaft, this stud 11, of course, being lengthened, and the substitution of the prolonged center 8 for the feed screw shaft for the short center for the feed screw shaft found in the existing one hundred thread machine. On the prolongation of the center 8 is placed the supporting frame 13 carrying the gear train as above described.

gears fixed thereto, of an upright carrying centers supporting one end of each of the Having now described my invention, what I claim 1s:

1. Ina phonograph, the combination of the mandrel and feed screw shafts having same, one of said centers being prolonged, a support pivotallymounted on the prolongation of said center, said support carrying 1ntermeshing gears adapted to be moved 1nto and out of engagement with said fixed gears, substantially as described.
