NEWMAN H. HOLLAND, OF WEST ORANGE, NEW JERSEY, ASSIGNOR TO THOMAS A. EDISON, INCORPORATED, OF WEST ORANGE, NEW JERSEY, A CORPORATION OF NEW JERSEY.

rrronoenarn.

To all whom. it may concern.-

Be it known that I, NEWMAN HJHOLLAND, a subject of the King of Great Britain, and a resident of West Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Phonographs,- of which the following is a description. 7

My invention relates to phonographs and more particularly to those adapted for use for commercial purposes, although obviously the invention may be used in connection with other types of phonographs.

The principal object of my invent-ion is to provide an improved recorder and reproducer support, preferably carried by the traveling carriageor carrier arm, and provided with means for operating the same so as to bring either the recorder or reproducer int-o operative position with respect to the record surface, or for bringing the parts into such position that both the recording and reproducing styli are entirely clear of the record surface so that the record cylinder can be removed from or placed on its support without contacting with either ofsaid styli, and the traveling carriage can be shifted without injury to either the record or the reproducer and recorder. A sound conveying tube to which an amplifying horn or other sound conveyor may beapplled is provided, and the recorder and reproducer are connected with this tube in such a way that when the recorder is inoperative position,

the interior thereof is in communication with the said tube, while the interior of the reproducer is entirely out of communication therewith, and vice versa. Means are also provided for rendering inoperative the mechanism for feeding the reproducer and recorder across the record surface when the support is being adjusted to place one stylus V position and remove the other Inorder that-my invention maybe more fully understood, attention is hereby directed to the accompanying drawing forming a.

part of this specification and in which Figure 1 is a central vertical sectional Specification of Letters Patent. Patented Dec. 31, 1912. Application filed amber is, 1911. Serial in, 653,154. 1

view of one embodiment of my invention, some of the parts being shown in elevation. Fig. 2 is a plan view thereof.

In all the views like parts are designated by the same reference numerals.

Referring to the drawings, reproducer 1 provided with stylus 1 and recorder 2 pro vided with stylus 2 are supported in a frame or slide 3. These instruments may be of any approved construction; but I prefer to arrange the reproducer at an angle to the recorder, as shown in the drawings, and to mount the reproducing stylus 1 in the lower surface of an offset 4 on the lever 5, which latter is pivoted to the reproducer casing and connected at its inner end to the diaphragm (not shown) of the reproducer. The neck 6 of the reproducer is formed with a substantially horizontal extension 7 from which depends a downwardly directed portion 8, the

end of which is pivoted as shown at 9 within an opening 10 in the upper part of the. frame or slide 3, this opening communicating with the substantially horizontal bore 11 of the slide 3. The pivotal mounting of the repro ducer permits the same to adjust itself to the eccentricity or other irregularities in the the bore 11 being closed at the end remotefrom that in which the tube 15 is received. This tube is pivoted, as shown at 16, between parallel ears 17 on the hollow member 18, which latter is provided with a sound passage forming a continuation of the sound passage in the said tube and is adapted to be connected with a sound amplifying horn or other sound conveying means (not shown). The tube l5 is capableof a considerable movement about'the pivots 16; so that my improved device is capable of adjusting itself to records differing in diameter to a large extent. The tube 15 is formed with a lateral opening 19 adapted to register with the opening 13, 14 and also with an opening 20 adapted to register with the opening 10, these openings in the said tube being so arranged that when one of them is in register with its corresponding opening in the slide, the other opening in the slide is closed by the tube. With-this arrangement, commuing in inoperative position and'out of communication with the interior of the sound conveymg tube 15;

In order to prevent rotation of the slide 3 on the tube 15', I provide a screw or other similar guide 22 secured to the tube 15 and having its shank extending through a longitudinal slot 23 in the slide 3. Thisslot is made of such a length that the ends thereof when brought into engagement with the screw 22, limit the movement of the said slide on the said tube so as to position the openings '19 and 20 respectively in register with the corresponding openings in the slide 3.

In order to provide convenient meansfor shifting the slide 3 on the tube 15, I pivot a lever 24 as shown at 25 to one of the cars 17 on the member 18 and connect the upper end of this lever, as by a link 26,-to the said slide. The numerals 27 and 28 represent screws or other suitable means for connecting the ends of the link 26 to the lever 24 and to the slide 3 respectively. The opening in the link 26 through which the member 28 passes is preferably slightly elongated as shown at 29 to permit the slide to move to a limited extent without imparting its movement to the lever 24.

In order to prevent damage to the. surfaceofthe record or to the stylus in engagement therewith, while shifting from one instrument to another, I provide means for elevating the tube 15 and the parts carried thereby during such shifting. In the embodiment of my invention shown, I employ a lever 30 pivoted as at 31 to a fixed partof the traveling carriage (not shown), the upper surface of this lever being formed -with a cam surface 32 adapted to beengaged by the pin 33 on the lower arm of the let-er 24. The pivot 31 is located to one side of the vertical plane passing through the center of the pivot 16, and the cam 32 is so shaped that when the lever 24 is swung from either extreme position to midposition, the upwardly extending finger 34 on the lever 30 comes into contact with the lower surface of the tube 15, and raises the latter, 1

the said tube and the portion 34 of the lever 30 being permitted to drop when the lever 24 passes beyond its midposition. As shown in the drawing, the lever 30 moves a. slight distance before contacting the tube 15, the clearance thus provided, together with that obtained by the slot 29 permitting my improved device to adjust itself to theirregularities in the record surface without affect-- ing the lever 24. 7

As stated above, my invention also contemplates the provision of means for render ing inoperative the mechanism for feeding the traveling carriage (not shown) and the 'reproducer and recorder and other parts supported by said carriage across the record surface, these means operating simultaneously with the shifting from one instrument to the other. As shown, the feed nut 35 is supported by lever 36 pivoted to a member 37 secured to the traveling carriage not shown). A spring 38 connected to the said lever 36 and the lower end of the member 37 tends normally to hold the feed nut 35 in engagement with the feed screw 39, The arm 40 of the lever 36 is provided on its upper surface with a cam 41 adapted to be engaged .by the lower. end of the lever .24

whereby movement of the lever 24 causes the nut- 35 to be raised out of engagement with the screw 39. The cam 41 is provided with a depressed central portion for holding the lever 24 in its midpositionand is I formed to permit engagement pf the nut 35 with the screw 39 when the said lever 24 is in either of its extreme positions.
