REPEATING ATLPAELAT'US Application filed Qctober 25, 192 3.

To aZZ whom iii may concern:

Be it known that l 11 3615 id. DAVEN- Born, a citizen oi the United ates residii at Camden, in the iounty or Camden a tale of New new and usetul Improvements in Repeating; Apparatus for Talking Machines of which the following is a specification.

One object of my invention is to provide improved apparatus of a durable character which will be etltective after the playing of record to automatically cause the record to be repeated.

Another object is to so make my improved tus that it can be readily applied my; machine and will be adjustable to 1L records of different sizes. These objects, and other advantageous ends which will be described hereinafter, l. attain in the following; manner reference being; had to the accompanying drawings in which Figu e 1 is a fragmentary top plan view of inv improved apparatus illustrates in the position assumes when mounted upon a talking machine, certain of the elements or the talinng machine being illustrate in dot-end-dash lines figure 2 is an elevation looking in the direction of the arrow Figure 1; certain of the parts being illustrated in section, gure 3 is an enlarged 'l ra mentary plan view of certain of the parts shown in Fin;- ures i and 2 parts dotted lines, 7l( A -1. E gine 1 is a iia ientary section taken on the line 4 i 01 Figure 2 and drawn on an enlar. ed scale, and

Referr'ng to the draw-7ings 6 represents the top or a talking machine cabinet above which the i" mounted;

record turntable by a center post or shaft 8 in the usual manor. A tone arm 9, which be of any construction capable of swinging in ver tical and horizontal plane, has sound be); 10 thereon adapted to co-act with a record placed upon the turntable 7, in the usual manner.

A bracket 11 is secured to the top 6 of the talking machine cabinet at one side of the turntable 7 and this bracket has an entension 12 providing a pivot 13 for a swing- TALKING- MIAQI-HNES.

A, suspension rod 15 is connectet to the end it; of the be n1 1-5: and has a weight 17 thereon adapted to move the hooked end 18 of the beam "ly under oer operating conditions. described. The weight 17 may oned within the cabinet and the "he cabinet may be provided with a to permit the rod 15 to extend the top 6 into the cabinet so that ht will not be exposed to view. A Frame 19 has one end pivoted at 20 to bracket 11; said frame having a worm i thereon whic is connected to a friction dish roller .22 adapted to frirtionally engage the nder surface oi? the turntable 7 as shown in i is the worm 21 will be rotated.

is secured to the shaft 24- and cranli' pin piv tally connected to The the link 28 is pivoted at 29 33 which is ally slid gun oway 31 formed in the top of 11. The rear part of the linlc adjacent the head blorl: 30 recess v2 therein. the inner end of which is beveled as shown 33 in Figure e head block 30 has a pin 34 lreely slidthe lower end o? a linlt or pitnian 28. upper end oil 1 to a nead blo 7 I q therein the rear end which is ad t- ;aged by a plate spring 35 which 0 the head blo'h 30. The spring 35 has a portion v-rhich extents above the top of the head block said portion being provided with a slot 36 adapted under certain conditions to engage a pin 37 on the beam 1 lhe plate spring normally tents to more the pin 34; toward the link and when the recess is entirely in trout of the pin the forward end of the pin :34 will l moved by the spring; into the recess and this n'iovement of the spring will cause its upper end to move out of engagement with the pin 37 on the beam 14. A swinging movement of the link 28 on its pivot 29, however, will cause the beveled part 33 to push the pin 34 rearwardly and also move spring 35 rearwardly and place it under tension. The top of the i springxiis preferably bent forwardly as shown at 38 in Figures 2 and 5 to permit the pin 37 to flex the top end of the spring 35 forwardly when the spring .35 moves upwardly as will hereinafter be described so that the pin 37 can enter the slot 36 to assume the position illustrated in Figures 2 and 5.

The friction wheel 22 is held in engagement, with theturntable 7 due to the connection of a spring 39 which is attached to the frame 19 and to a lug 40 on the bracket 11. A latch lever 41 is pivotally connected at 42 to the bracket 11 and has a torsion spring 43 adapted to move the lower arm 44 of the lever-41 intoengagement with the frame 19 under certain conditions and move thefriction roller 22 downward out of engagement with the turntable 7. The upper arm 45 of the latch lever 41 has a hook 46 thereon adapted to engage over a shoulder 47 on a latch 48; said latch being pivoted at 49 to the beam 14 and being located adjacent a side surface 50 of the bracket 11. A trip lever 51 is pivoted at 52 to the bracket 11 and has a shoulder 53 on its lower arm 54 which is adapted under certain conditions to engage over the top 55 of the frame 19 at a position remote from its pivot 20. The upperv arm 56 includes a section 57 adjustably pivoted thereto at 58 as shown in Figure 2. The beam 14 is adapted to extend under the tone arm and the parts of my inventionare operativeafter the playing of the record to lift the tone arm through the medium of the .beam 14; thebeam 14 slanting so as to cause thetone arm to slide downwardly toward the pivot 13 and then be lowered with the reproducing needle in the outer grooves of the record. 'Figure 2 shows the parts in the position which they assume just prior to the time in which the reproducing needle will be lowered into the outer. grooves of the record.

A clamping band 59 is secured to the part 60 of the tone arm which receives a pivotal movement in a horizontal plane and said clamping band 59 has a projection 61 which .is connected to a link 62. The link 62 as medium of the projection 61and link 62 to push the arm 44 upwardly out of engagement with the frame 19 and thereby permit the friction roller22 to again engage the turntable 7. It will be noted that the upper :arm'56 of the trip lever 51 is offset so that the weight of the'upper arm normally tends to move the lower arm 54 to cause the shoulder 53 to move over the top 55 of the frame lever 41.

Considering that the crank pin 27 is moving downwardly, as shown in Figure 2, to move the beam 14 downwardly due to the connection between "the link 28, head block 30, spring 35 and pin 37, the tone arm, having been previously swung to its outermost position, will be lowered to present the needle t0 the outer grooves of the record. When the crank pin 27 reaches its lowermost position the hook 46 of the latch lever 41 will be moved over the shoulder 47 of the latch 48 and the arm of the latch lever will move down into engagement with the frame 19 and swing the frame 19 against the action of the spring 39 to move the friction roller 22 down out of engagement with the turntable 7. The section 57 of the trip lever 51 being free of the tone arm will allow the shoulder 53 of the arm 54 to move overthe top 55 of the frame 19 and thereby prevent the frame 19 from moving upwardly until the tone arm again strikes the section 57 which will not occur until the nextrepeating action.

After the record has been completely played, the end 66 of the trip arm 63 will have been actuated so as to inove the adjusting screw 67 into engagement with the arm 44 of the latch lever 41 and the latch lever will then be swung against the action of the spring 43 to pull the hooked end 46 out of engagement with the shoulder of the latch 48 and to move the end 44 of the lever 41 away from the frame 19. The pin 34 having previously moved into the recess32 so as to free the pin 37 ofv the spring 35, the counterweight 17 will sn ing the beam 14 on the pivot 13 and will lift the sound box out of engagement with the record and, due to the slant of the beam 14, the tone arm will slide downwardly thereon until it engages and moves the section 57 of the trip lever 51 and will then move the shoulder 53 away from the top of the frame 19. The frame then being released will be moved by the spring 39 to cause the friction roller 22 to again engage the turntable and thereby actuate the worm 21 to turn the crank and to thereby effect the movement of the head block 30 and spring upwardly so to'cause the pin 37 to engage through the slot 36 as previously described and a continued movement of the crank will cause the beam 14 to be moved downwardly having been caughtby the spring 35 and the sound-box will be lowered so as to cause its reproducing needle to again engage the outer grooves of the record to repeat the playingof. the same.

turning theadjusting screw 67, the timing of the releaseof the latch lever can be varied to suit different requirements as to the size of the playing portion of a record,

1,444,171 are and the section 57 of the trip lever 51 can also be swung into various positions so as to vary the position at which the release of the frame 19 by the arm 54 will be accomplished.
