UNITED STATES PANAGEOIIS M. TRICAS, F LOS ANGELES, CALIFORNIA.

PHONOGRAPH REPEATER.

Application filed March 18, 1924. Serial No. 700,057.

To all whom it may concern:

Be it known that I, PANAGEOTIS M. TRIoAs, a citizen of Greece, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Phonograph Repeaters, of which the following is a specification.

My invention relates to phonograph repeaters, and consists of the novel features herein shown, described and claimed.

The objects and advantages will appear from the drawings and specification.

The drawings illustrate the invention.

Figure 1 is a fragmentary top plan of a phonograph record mounted for operation and a phonograph repeater embodying the principles of my invention in position for use, the repeater being extended for a. twelve inch record and as seen looking downwardly in Fig. 2, as indicated by the arrow.

Fig. 2 is a vertical diametrica-l sectional detail as indicated by the line 22 in Figure 1.

Fig. 3 is a fragmentary plan of the phonograph repeater adjusted for a ten inch record.

. Fig. 4 is an enlarged cross sectional detail on the line 44 of Fig. l.

The details of the phonograph repeater are as follows:

The turntable 1 is mounted on a vertical rotating spindle 2. The felt pad 3 is mounted on the turntable 1 and the disc record 4 is mounted on the pad 3, the spindle 2 extending through the center of the record 4.. A pad 5 is mounted upon the record 4 and the spindle 2 extends through the pad 5. d

The phonograph repeater is stamped and formed of sheet metal. The dished hub portion 6 is mounted upon the pad 5 with the spindle 2 extending through the center of the hub. The pad 5 serves as a friction device tending to rotate the repeater. The arm 7 extends radially from the hub 6 and has a long slot 8. The arm 9 extends radially from the hub 6 substantially at right angles to-the arm 7 and the pick up blade 10 extends from the arm 9 and the track arm 11 extends from the pick up blade 10. An inner track bead 12 extends upwardly from the edge of the pick up blade at the junction of the blade with the arm 9 and along the inner edge of the track arm 11. A track flange 13 extends upwardly along the outer edge of the pick up blade 10 and track arm 11, the bead 12 and flange 13 converging and coming nearly together at their outer ends to make the track having a wide receiving end and a narrow discharge end. An ear 14 extends outwardly from the outer end of the track and a button 15 is fixed in the ear and extends down wardly. p v

An extension track plate 16 has a. slot 17 through which the shank of the button 15 extends, the head of the button being below the extension plate. A track flange 18 extends upwardly from the outer edge of the plate 16 and is adapted to register with and form an extension of the flange 12 when the repeater is adjusted for a ten inch record as in Fig. 3. A bead 19 extends upwardly from the plate 16 and is adapted to register with and forman extension of the bead 12 when the repeater is adjusted for a twelve inch record as in Fig. 1.

An arm 20 extends from the plate 16 under the arm 7. A button 21 has a shank ertending through the slot 8 and fixed in the arm 20. The slot 8 has gear teeth 8 along one side. A pin 22-is fixed in the arm 20 and extends upwardly through'the slot 8. A pinion 22 is mounted uponthe pin 22 in mesh with the gear teeth 8 and a knurled head 22 is formed integral with the pinion 22 and the upper end of the pin 22 extends through the head 22 and has a head 22 fitting loosely so that the head 22 and pinion 22 will rotate freely upon the pin 22 and so that by manipulating the head 22 the plate 16 may be moved from the position shown in Fig. 1 to the position shown in Fig. 3 and vice versa.

An enlarged neck 24 extends from the plate 16 and forms an extension of the flange 18. A guide bar plate 25 extends from the neck 24. An extension guide bar plate 26 fits upon the plate 25 and has a long slot 27. A button 28 extends through the slot 27 and is fixed in the plate 25. The slot 27 has gear teeth 29 along one side and the knurled head 30 carries a pinion engaging the teeth 29 and is secured in place by a pin 30 fixed to the plate 25 so as to form an adjustable sliding connection between the plates 25 and 26 and so that by manipulating the head 30 the guide plate may be lengthened assho'wn in Fig. 1 or shortened as shownin'l ig. 3.

The adjustable guide bar 25-26 is spaced from the parts 20 and 7 and the edge 31 is straight and finished so that the needle 32 will slide smoothly along the edge 31.

The needle 32 hearing against the edge 31 will hold the repeater from rotating and when the needle travels inwardly beyond the inner end of the edge 31 the repeater will be released and will rotate until the pick up blade 10 comes around and passes under the needle and picks up the needle, and then the needle will move outwardly on the arm llbetween the bead 12 and flange 13 and over the extension track plate 16 and drops in front of the edge 31 and holds the repeater from further rotation and repeats the record.

Thus I have produced a phonograph repeater comprising a friction hub, a pick up bla'd'e carried by the hub, a track extending from the pick up blade, an extension track slidi'ngly connected to the track, overlapping arms extending from the extension track and from the hub, means for securing the arms together in'adjusted positions, and an extensible or contractible guide arm carried bythe extension track.

A stop. 32 extends upwardly from the outer end of the edge 31 so that when the needle passes from the track to the guide bar it will strike the stop and not pass over the stop.

7 Various changes may be niadewithout departing from the spirit of my invention as claimed.

I claim:

1. An adjustable phonograph repeater comprising a flat hub adapted to fit upon a spindle'oif a phonograph and bear upon a record, an arm extending from the hub, a pick up blade extending from the arm, a

track extending from the pick up blade, a second arm extending from the, hub substantially at right angles to the first arm, and an extension track means adjustably connected to the first track and to the second arm.

2: An adjustable phonograph repeater comprising a hub portion, a pick up blade extending from the hub portion, a track ex tending from the pick up blade, an arm extending from the hub, an extension track slidably connected to the first track and to said arm, and means for holding the extension track in adjusted position.

3. In a phonograph repeater, a hub, a

pick up blad carried by the hub, a track leading from the pick up blade, an extension track slidingly connected to the outer end.

of the first track, overlapping arms extending from the hub and from" the extension track, and means for adjustably connecting the ovelapping arms. v I

4. An adjustable phonograph repeater comprising a flat hub adapted. to fit upon a spindle of a phonographand bear upon a record, an arm extending from the hub, a pickup blade extending from thearm, a track extending from the pick up of the blade, a second arm extending fromthe hub substantially at right angles to the first arm, an ear extending outwardly from the outer end of the track, a button fixed in the ear and extending downwardly, an extension track plate having a slot through Which the shank of the button extends, the headof th'e button being below the extension" plate, an arm extending from the extension track plate and overlapping the second arm, and means for adju'stably connecting the overlapping arms together. I

In testimony whereof I have signed my name to this specification.
