To all whom itmay concern Be it known that I, PETER WEBER, a citizen of the United States, and a resident of useful Improvements in Talkingand more particularly,

"disk' record having vertically undulating record impressions isoperated upon.

Orange, in the county of Essex and State of NewJersey, have invented certain new and Machines,

of which the following is a description.

- My invention relates to talking machines but not exclusively,

to machines of the type in which a flat or The principal object of my invention is the rovision of improved means for controlling the feeding of the reproducer across the record surface, these means being preferably soconstructed and arranged as to position the reproducer on or withdraw the same from the record, surface simultaneously .with the engagement and disengagement resepectively of the usual feed nut and feed screw. 1 4 Another object of my invention is to pro vide .a novel construction and mounting for the reproducer, whereby the stylus is permitted to follow the record groove regardless of irregularities therein. In conformity with this last named object, I preferably so mount the stylus supporting member. movducer so that the stylus has great freedom in-tracking the record groove and a mount-- ing of small inertia is obtained.

In order that my invention may be better understood, attentionis hereby directed to the accompanying drawings forming part of this specification, and in which- Figure 1- represents an elevation "partly in section of a portion of .a talking machine embodying my invention; Fig. 2 represents a plan view partly in section taken on the hue of F1g. 1 of certain details of constructlon; Flg. 3 represents aside elevation of a modified fo'rm of a detail of construction; and Fig. 4: represents a side elevation partly 1n central vertical section of a modified form of reproducer constructed in accordance with my invention. 7

- In all of the views, like parts are designated by thesame reference numerals.

Referring to the drawings, the sound reproducer 1 comprises a diaphragm 2 mounted in a casing or support 3, an arm 4 hinged to the casing as at 5, and connected to the 5 center of the diaphragm,

and an arm 6 carproducer, asshown, ably with respect'to the body of the reproconduit 24.

rying a stylus 7 and pivoted, as at 8, to the arm 4. The arms 4 and 6 extend substantially parallel to the diaphragm 2. and the surface of a record 9 mounted on the rotatable table or support 9', the .arm' 6- being preferably yieldably held in its central position, as by a tension spring 10 connected to an extension 11 on said arm and a lug 12 depending from the arm 4:.

The reproducer shown and ,described above is adapted for use with records having vertically undulating record impressions, the mounting of the stylus in the pivoted arm 6 permitting the stylus to oscillate laterally and thereby faithfully. follow the rec- 0rd groove regardless of the irregularities therein.

The reproducer is secured to the arm 13 of a sound conveyer or conduit leading to an amplifier 14:, this arm'being provided with a ball and socket

joint comprising twdmembers

15 and 16 connected by a pivot 17, whereby an up and down movement of the reproducer is permitted. 7 the reproducer is limited by the engagement of the member 15 with the shoulder 18 on the member 16. The arm 13 of the sound conveyor is rearwardly directed from the reto a bend 19 whence'it descends vertically as shown at 20 through a bearing 21 in the-to ing. The vertically ected portion 20 of the said arm is preferably closed at its lower end and is provided with a lateral opening 23 in register with the opening in the end of the horizontal portion of an angular sound conduit-2 1 which is rigidly secured to the bearing 21. The opening 23 is made of considerable width so as to permit pivotal movement of the arm 13 Without closing or partially closing the said opening in the The lower end of vertical portion 20 of the arm 13 carries a pivot 25 whereby the said arm is rotatably mounted on abearing 26 which is supported upon and capable .of being adjusted vertically and the 1111151 end of the amplifying horn 14 1 are secured together by

flanges

29 and 30.

Thebearing 21,- as shown, is provided with 31 secured to the top of the motori casing, the vertical portion 20 of the arm 13 being provided with an annular projecting portlon 32 adapted to en- This movement ,of

port the arm 13 when the pivot is su ciently lowered or is removed.

In order to provide means for positively feeding the reproducer across the record surface, I provide a sector 33 having gear teeth 34 upon a flange 35 at the forward end thereof, this sector being supported from the inclined central portion of a bracket 36 by a horizontal pivot 37. The bracket36 is provided at its ends with upper r I gage the portion 31 of the bearing 21 to sugand lower horizontal portions 38 and 39 'respectively, the lower portion 39 being formed with a collar 40 surrounding the portion 20 of the pivoted sound conduit and secured thereto by a screw 41. The teeth 34 on the sector are adapted to beheld by the action of gravity on the pivoted sector in mesh witha suitable driving member, such as a worm 42 mounted on a shaft 43 con nected by

suitable gearing

44 and 45 to the motor shaft or spindle 46 which carries the The sector 33 is provided with an opening 47 through which extends a vertical pin 48 supported by the portion 38 of the bracket 36. This pin extends near its lower end through an elongated radial slot 49 in a fiange50 projecting horizontally from a "downwardly directed porthe sector when .asto'make tion 51 of the sector. By reason of the above construction, the rack 33 is capable of a limited up and down movement about its pivot 37, so as to permit the teeth 34 to be engaged with and disengaged from the worm 42. 'Nuts 62 are threaded on the lower end of the pin 48 to limit the downward movement of the Worm 42 or the motor is removed. J 4 In the embodiment shown in Fig. 1, the teeth on the sector are disengaged from the worm 42 and the reproducer lifted from the record surface by the following mechanism:

lever 53 is pivoted between lugs 54 depending from the arm 13 and is provided at its forward end with a theouter end of which is adapted to engage the member 15 between depending ears or lugs 56. The lever 53 ispivotally connected at'its opposite end with a link 57 provided at its lower end with an enlarged head 58 bearing on the top of the extension 59 on the sector 33, the head 58 being provided W1tha pin 58' extending looselythrough an openln in said extension. This link is preferably ormed in two sections 60 and 61 having a threaded connection as shown at 62 so possible an adjustment of the effective length .of the link. The section 61,is weighted as shown at 63 to hold the head 58 in engagement with the sector, a knurled flange 64 being provided on the section 61 to adjust the length of the link. 'A forked lever 65. provided with a handle 66, extends over the arm 13 and is secured at its lower end to apivot 67 mounted in depending lugs curved portion 55,

68 on the said arm 13, a cam or projection I 69 being also secured to the pivot 67 between the lugs 68 and being adaptedto engage the forward arm of the lever 53. The numerals 70 and 71 represent stops for limiting the movement of the lever 65. It is evident that by merely drawing the lever 65 forwardly, the rear arm of the lever 53 is depressed to cause the link 57 to raise the forward end of the sector and thereby disengage the teeth 34 011 the sector from the Worm 42 and the forward arm of said lever 53 is raised to lift the reproducer from the record surface.

In the modification shown in Fig. 3, the lever 65' is pivoted intermediate its ends, as at 72, to the arm 13 and is provided adjacent its-lower end with a pin or projection 73 adapted to engage the curved portion 55 of the lever 53 to cam the forward end of the latter upwardly and lift the reproducer from the record surface, when the upper end vof the lever 65 is moved rearwardly. The numeral 71 represents a stop for limiting the movement of thelever 65' when the reproducer is lifted from the record surface.

In Fig. 4 I have shown a form of my 'improved reproducer provided with a floating weight. In this figure the arm or lever 6 is provided with a stylus 7, and is support ed, as by a pivot 8, from the arm 4 which is pivoted at one end, as at 74, to a floating weight 75 hinged to the diaphragm casing A or support 1. The'opposite end of the arm 4 is connected, as'by a link 76 to the center of the diaphragm 2. A spring '10 con nected to the stylus carrying end of the arm 6 and to a hook 77 on the floating weight serves to hold the said arm in central position. The. arms 4' and 6 are located substantially parallel'to the floating weight and the diaphragm 2' and are adjustable similarly to the arms 4 and 6 shown in 1 during thetrac'king of the record groove by the stylus.
