CORPORATION OF NEW JERSEY.

PHONO GRAPH.

Application filed April 5, 1911.

To all whom it may concern:

Be it known that I, About! F. GALL, a citizen of the United States, 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 descrip tion.

My invention relates to phonographs and more particularly to an improved connection between the reproducer and sound conveying or reproducer arm of a phonograph.

The principal object of my invention is to provide an improved connection particularly adapted for use with a meclumically fed sound conveying arm whereby the reproducer is capable of adjusting itself to irregularities in the record groove and of being readily lifted from the record surface.

Another object of my invention is to provide. an improved means for lifting the re producer and positi ning the same on the record surfa e.

)thcr objects of my invention will appear more fully in the following specification and appended claims.

in m'der that my invention may be more fully understoorh attention is hereby directed to the accompanying drawing forming part. of this specification and in which l 'igure l is a side elevation of my improved device applied to a reproducer and reproducer arm: Fig i? is a central vertical section of the re n'oducei' arm and my improved connection, the reproducer being shown in side elevation; l ig. 3 is a plan view of the reproducer and the connection for securing the same to the reproduccr arm; Fig. 4 is a section taken on line -l---l of Fig. 3; and Fig. 3) is a fragmentary elevatioi of my improved positioning means.

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

Referring to the drawings, the numeral 1 represents a reproducer provided with a stylus arm 2 having connected therewith at its lower end a reproducing stylus f5. lhe arm 2 is provided on opposite sides thereof with pivots 4. whereby the same is pivotally mounted in brackets 5 mounted on av plate 6 which is secured in any desired way to the body of the reproducer.

The numeral 7 represents a hollow neck adapted to be connected with the sound con- Specification of Letters Patent.

ve-ying arm 8 by a hollow connection 9 so that the sound vibrations may be transmitted from the reprmlucer to any suitable amplifyingmeans (not shown). The connection 9 comprises a hollow member 10 adaptet to be detachably engaged with the outer surface of the neck 7. the member 10 being provided with a substantially hemispherical socket 11 adapted to receive a sound conveying member 12 having a curved outer surface fitting loosely in the socket 11. The member 10 is connected to the member 112 by alined pivots '13, on which it is horizontally movable. The side of the member 1'. opposite to that engaged within the member 10. fits loosely in the substantially hemisplwrical socket 14 formed in a sound conveying member 15 which is adapted to detachably engage within the sound conveying arm h. the member 15 being pivoted l'or vcrti 'al movement relatively to the member 19, by alincd pivots lb secured to the member 12 and having their axes at right angles to the axes oi the pivots 13. The axes of the pivot l3 and in. as shown in the drawing. all lie substantially in the same plane. In order to permit 'l'rcc movement of the member 10 with respect to the member 15. these members are spaced a slight distance apart. as shown in Fig. l. the pivots l3 and 16 extending through cars or brojections l7 and .18 respectively on the membcw 10 and 15 rcspcc tively lleccsscs l1? and 20 of sutlicient size to loosely receive the projections 17 and 1% but coacting therewith to limit the lateral as well as the up and down movement of the reproducer are formed opposite the said projections in the members 15 and 10 respectively. The members 10 and 15 are provided with open ended longitudinal slots 10 and 15' so as to permit them to yieldingly engage the neck T and the arm 8 respectively. The slots in each nember are preferably placed diau'ictrically oppositeeach other, those in the member 15 being adapted to engugc a vertical rod in the arm 8 to prevent the connection 9 from turning in the arm 8 and to limit the inward movement of said connection. By means of the above described connection, the reproducer is given sutlicient play vertically and laterally of the record groove to permit it to follow the irregularities in the record surface.

For positioning the reprodueer with respect to the record surface, I provide an arm or lever 20 having a substant ally flat horizontal portion 21 provided at its right hand end with a curved portion 22 embracing the member 12 and mounted at its ends on the pivots 10 outside of the pro ections 18. The opposite end of the portion 20 is provided with a substantially vertically ex tending portion 23 curved at its upper end as at 24 from which last named portion, the lever projects to the left as shown at 25, being provided at its left hand end with a finger hold 26. The portion 23 is provided with an aperture or recess 27 inclos ing a pin or projection 28 secured to the reproducer. The aperture 27 is provided at its lower portion with inclined converging walls, as shown, and is of sufiicient size to permit the projection 28 to move freely therein when the reproducer is trackmg the record. By grasping the arm or lever 20 at the finger hold 26. the lever may be lifted to bring the projection 28 into engagement with the inclined walls of the aperture 27 so as to position the reproducer centrally with respect to the arm 8 as shown in Fig. 5 and also to permit raising of the reproducer from and positioning of the same on the record surface. The arm 20 has a tendency to move by gravity into engagement with the reproducer; and in order to prevent said engagement while the reproducer is tracking the record groove, a slot 29 is formed in the portion 21 of the said arm, the righthand end of thisslot engaging with the upper pivot 13 to prevent downward movement of the left hand end of the said arm.

While I have described and shown the preferred embodiment of my invention, many changes may be made therein without departing from the spirit thereof; and I do not. therefore, wish to be limited to the specific structure shown and described.

What I claim as new and desire to secure by Letters Patent of the United States is as follows 1.
