Be 'it lmoivn that .I. NEWMAN H. 'HOL- LAND, a'subject'of tlieKiiifr of Great Britain.

and a, resident ofdllfest Orange.' in the :county of Essex and State 'of New Jersey,

have invented certain new and useful .Intv

proveniente in.'Phonograpli-Reproducers of which the following is a description.,

producers and more particularly to phono-l graph-reproduce@ adapted to operate fon sound' records having` record undulations of the Aup 'and down or hill and dale type.

A-The principal .object of' luy invention is the provisionof an iniproved mounting for the stylus lever forming apart ot the 1re-1.

producer whereby tlie'stylus will be'capable of tracking the record groove'faith'l'ully re- 'jump from its proper position-across the :side Walls of the record 'groove Sired' balance .is provided. for' in rny "inven-l tion by shaping' the ioating 'Weight' sym- 'metrica-lly with respect to the laxis about which its later'alrnovement takes. place.

Other objects of. my. inventionreside in theA improved details of. construction and combination of parts la'ereinaftajl 'I'nore fully described and claimed.

The pivoting',t means comprising the L- shaped bracket 13, 14 and the stud 1C are of vervsmall weight relativel)` to the weight 17 and the downward pressure of the latter on the stylus is accordingly tar in excess ot'vthat due to the sa-id pivoting means.

It will be understood that mv invention is not limited to the precise details and construction shown but iuay be varied within the scope ot the appended claims without departing from the spirit ot' mv invention.

, Having now described inv invention what I claim as new and desire to protect bv Letters Patentis as follows:

l. In a device of the class described, the. combination of vibratorv means, a s vmmctrical weight. means for pivoting said weight for movement about an axis parallel to said The pivoting\ vibratorv means and also t'or lateral oscillameans may weigh about 1.5 grams and the tion about its` axis ot' svmmetrv. afstvlus weight about 1S grams.

It will be seen that the weight 1i' is not supported by the. pivotinr means l?. 1l and 1G and is movable longitudinally or axially ot' the stud 1G: and in order' to preventI displacement ot` the said weight :trom the saidV stud and also to limit the downward move-j',

meut ot the said weight upon the disengagement of the reproducer from arecord, a pin :2G secured in the weight 17 and is confined within the stirrup or loop 2T secured to and extending downwardly from the sound bon-` bod'v. referring to Figi -.l. it will be seen that thc lower portion of the loop 2T lis in the shape of a vertical V; so that upon the disengagement ot the reproducer from the record.v the projection 2G is guided b v the loop-to a position in the vertical center line of the loop. and the weight 1T and the st vlus lever carried thereb)1 arc eiiectivelv centered.,

ln operatiolnthe weight lshould always beaA up against the enlargement 1S onilae stud ib. ln order to assist inniaintaining the weight in tl'iipositionwith respect to thestud; -l )')iet'erablv emploiv aspring'QS tending to press the !..shaped bracket l?. 1l downwardl)v toward the weight. One end of thisspring bears against the wall ol the recess 29 in the arm 12. the other'end presslever supported bv said weight and connected with said vibratoiv means. an d\a stylus carried b v said lever. thc pivot of said lever beinf.;Y spaced from the axis of s vmmetrv Yot' said weight and being' located between saidV st vlus and-said axis ot s vmmetrv. substantiall)1 as described.

i). In a device of the classdescribed. the, combination of vibratorv means. a s'vmf metrical weight. means 'for pivoting said weight for' movement about an axis parallel to said vibrator)v means 'and also lor lateral oscillation about its axis of s vmmetry, re silient meansl for maintaining/said pivot-ing means and said weight in proper relative position. a st vlus lever supported b vsa'id weight and connected with said 'ibratorv means. and a st'vl'us carried liv said levcrgthe pivot of said lever-bein;r spacedfrom the axis ot' `s)v/1mnetr v ot said weight and being located-between said st vlus and said axis of svnnnetrv, substantially as described.

3. In a device of the class described, theV combination ot vibrator-v means. a symmetrical weight. means for pivotirr;y said weight,- for movement rabout van axis; parallel with `aid vibratonv means 'and also ior 'lateral oscillation about its axis ot svmmetry.- a1 st vlus lever supported b v said weight. and

In a. device of the class described, the combination of vibratory means, a symmetrical weight, means for pivoting said weight for movement about an axis parallel to said vibratory means and also for lateral oscillation about its axis of symmetry, said means permitting movement of said weight along its said axis of symmetry, resilient means tending to maintain said pivoting means and said Weight in proper relative positions, a

' stylus lever supported -by said weight, and

ing means to hold the same in operative relation to said Weight, and a stylus lever supported by said weight and connected with said vibratory means, substantially as described.

7'. In a device of the class described, the combination ovibratory means, a symmetrical weight, means for pivoting said Weight 30 foi" movement about an axis parallel with said vibratory means and also for lateral oscillation about its axis of symmetry, the weight 'of said pivoting means being less than that of said symmetrical Weight, a

stylus leversupported by said Weight, and means connecting said stylus lever to said vibratory means, substantially as described. This specification signed and witnessed this 27 th day of June, 1913.
