d Application Sled January 28,51909LKV Serial No. 474,835.

To all 'whom 'Zt may concern:

Be it known that I, HARRY B. MCNULTY,

citizen of the United States, and a resident of East Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and use- 'ul Improvement lin Phoiiograph-Reproducers, of which the following is a speciiication, the principle of the invention being herein'explained and the best inode in which I have contemplated applying that principle so as to distinguish it from other inventions. f The object of the invention is the provision of a reproducer for use in a phonograph intended to optionally play upon records having 100 and 200 threads to the inch, re-

spectively, or as they are currently known, two-minute and four-minute records. The subject matter of this application, it should further be explained, has inthe main been divided outv of my co-pending ap lication filed November 9, 1908, Serial3 No. 463,942, wherein such reproducer is shown in conjunction with suitable mechanism for automatically adjusting the same lfor the two uses in question.

Said invention, then, consists of the means hereinafterjully described and particularly pointed out in the claims. j

The annexedy drawing and the following description set forth in detail certain mech- ,anism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing: Figures 1 and 2 are partly sectional and partly side elevational views of a reproduoer embodying the improvements in question, with the stylus lever shown in operative and inoperative position, respectively; Fig. 3 is a perspective view of the stylus lever of such reproducer; Fig. 4 is'a similar perspective Iview of a slightly modied form of such stylus lever;

.and Figs. 5 and 6 are respectively `a per- -lspective view and a transverse section of a stud or pin for supporting the stylus lever Ion the floating weight of the reproducer.

The general features of construction entering into my improved reproducei, will require to be only briefly noted, consisting as they do of a body A. of familiar form wherein is held the usual diaphragm a, and to which is pivotally attached the floating weight a. On the latter is iii turn mounted the Stylus lei-er A'. It is to the construe Patented Oct. 1910.

tion of the stylus lever, and to the manner in which itis mounted uponV the floating weight, that attention .is more particularly desired in the present connection.

Referring lo Fig. 3, lever A will be seen to consist, instead ofthe usual bar, of a 'y sleeve a2 within which is rotatably held a" pinaa, that constitutes the stylus holder kproper. Suitable means, as a transverse pivot pin a* and an eye a5, are provided for attaching the sleeve tothe plate a and to the link a, respectively.` `This sleeve is longitudinally split and provided with an adjusting screw a" adapted to secure the pin a3 more or less tightly therein, as desired. At its outer end such pin'or rotatable portion a.3 of the lever is provided with two Sapphires as a, that constitute the styluses .l

proper, and contact with the record when the reproducer is in use. j Such styluses are disposed at substantially right angles to each other about the axis ofthe in or holder, and are respectively adapted or the fine and coarse line records. Obviously in one angular position of the holder about its axis, the one stylus is brought i-nto operative position, while, in another position of such holder, the other stylus is thus disposed.

Styluses a a are not located at the extreme end of the pin, or holder in the specific structurev shown ,in Fig. 3, but such holder projects a short distance therebeyond and is squared, as at al", so as to permit engagement therewith of a key B that is mounted on the under side of' the annular `holder B wherein the reproducen is seated,

being movable longitudinally in a line with the stylus holder a when the latter is in its -the v numerals two and four respeci tively, facilitate rotation of the key, and

' struction,l it shoul at the same time indicate which stylusv is thus operatively disposed.

lt will be obvious,

endiof the vpin a, constituting the stylus or likey device, and in the form of lever illustrated in Fig. 4, I thus show the rear .end a of the pin prolonged and squared,

adapting it for operation by a key mounted oii the opposite side of the reproducer holder from that illustrated in Figsrlv and .2.

While it has always been fou-nd that a little play is necessary in the pivotal mounting of the stylus lever A ony the floating weight of thereproducer for the reason that the thread of the record is apt to be a trifle distorted in curing the latter, especially where the material used in its construction is Celluloid or of like composition, obviously this distortion will have a relatively greater. ellect in the case of records such as the. four minute records referred to herein, where the .threads are finerv and .more closely crowded together. It 'accordingly becomes desirable to provide forthe lateral oscillation of the stylus lever as well as for its movement labout itstraiisverse axis, and not merely to trust to the looseness of the lit-y ting of the stud C that secures the lever to the plate, or to the looseness of the pivotal pin a* itself in such stud. To this end I provide such stud with a transverse slot c,

or rather aperture,'of circular cross-section,

that is intersected by the vertical slot c in which the lever plays. pivot pin of the lever rest inr the portion of such aperture on either side of the intersecting slot sothatwhile such pin is thus held against dislodgment, it is nevertheless free to assume various angular positions about the axis of the stud. At the same time thevfreedom of its normal movement in the lane of such axis is not interfered with in the least. This articular pivot pin con-v dp' be explained, forms no part of the present invention, being described and claimed in my co-pending application, Serial No. 472,688, filed January 16 1909.

Other modes of applzying the principle of my invention may cmplo en instead of the one explained, change ein made as regards the mechansmherein disclosed,V

rovided the means stated by any of the folowing claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention 1.
