WALTER n. MILLER, or n es;

COMPANY, or wash onancn,

1501i it may concern: .gBe itknown that I, WALTER H. MILLER, a citizen of the United States, and a resident of Orange, in the county of Essex and State oft-New Jersey, have invented 'certain new useful Improvements in Phonographs, at which the following is a specification.

My invention relates to phonographs and articularly to phonograph horns and means gar supporting the same, and to an improved arrangement whereby a permanently. positioned section of the horn may be connected with the movable reproducer; It has been mmmon heretofore to project the horn forwardly from the machine and to'support it lnovably upon a horn crane or equ1valent-.-

device; Inforder to avoid'the' objections incident to this form of arrangement of tzrn an to permit the'use of a horn sufficiently large to obtain the best reproduction, it has been proposed tomount a section of the horn rigidly'or rotatively upon some portion of .the machine or a bracket connected there- -With and thus permit the horn to extend from the rearof the machine overthe ma-,.; chine and in front thereof; but in all such devices of which. I am awareit has been found necessary, n mak ng connections bemounted and the neck of the phonograph reproducer which in the phonograph and tide a telescopic connection or its equivalent tween the horn so rigidly or rotativelyf t!" so that thecommunication between the reproducer neck and' the permanently positioned horn section may be maintained not- '=jwithstanding the jmovement of the repro- ,ducer. These telescopic or-equivalent connections, so far as Iain aware, have been so arranged that bending and twisting. stresses have been imposed upon the telescoping parts. In a devicelconstructed in accordance with my improvements all such bending and twisting and'similar stresses are eliminated and the telescopic "connection is enabled to perform. its function without stresses or strain of any kind. This'result is accomplished by rigidly and permanently connecting a tube, refer-ably cylindrical in formt'and having th elements of its walls parallel to one another, in such a position thatiits longitudinal axis is parallel to the path traversed by the phonograph reproducer' in its movement transversely to the- 7 form of construction which will secure result may be used, Wltlllllth scope of my NEW JERSEY, ASSIGNOR. TO NEW JERSEY PATENT NEW JEnsnY, A conronarroivor NEW JERSEY.

record surface. One end of this tube comif tapered telescoping section-is connectedfwith the neck of the phonograph reproducer and travels within-the cylindrical tube as the reproducer mores to and fro. Since 'the travel of the 'reproducer is in a line parallel to the principal axis of the fixed tube, the member connecting the tube to the reproducer neck snnply slldes back and forth' in the said fixed tube. in straight lines without creating any stress or strain of any nature? It is desirable that the hollowmember which slides in thefixed tube be so arranged that it can be disconnected from the neck of the reproducer and for this reason I construct the said sliding hollow member in sucha fashion that it is capable ofQuniversal motion with respect to the tube wherein itslides. Any this inventionbutl have shown and prefer to make the. sliding member tapering 1n form,

7 the smaller end being that communicatingv with the reproducer neck'and having the edges around'the opening in its larger end turned inward somewhat so as to form in thisneighborhood what is substantially a ball joint.

, 'In'order. that my invention may be more fully understood, reference is hereby made to the accompanying drawings which form a part of this" specification and wherein the,

same numerals offreference areuniformly used to designate-the same parts. j I

In the drawings Figur'el 1s a front elevational view, showing my improved; horn and connections appliedYto aphonograph which latter is shown in dotted lines; and Fig. 2 is a detail sectionalview,showing-the slidable member for connecting the fixed tube and the reproducer neckin itsraised" position in which" it can be disconnected fromthe neck of the reproducer. y

In the drawings the numeral 1 indlcates the phonograph to which my improvement is applied. I have-found it convenient to connect my rigid tube, which is arranged. "parallel to the path traversed by the'phonograph .reproducer, to the phonograph by means of a bracket secured to the rear of the phonograph and extending upwardly and forwardly and toward the end of the instru-' ment 'n su'cha manner that the rigid tube on the centrat-longitudinal line'of the in jl th' of t nated by the reference numeral t,v It is to be understood that, while I prefer to provide the common supporting means for the mouth piece4 and the rigid tube 3 in the neighborhood: of one end of theinstrum'ent and at a Shortdistance thereabove,'these devices may as that which I have described and shown.

As the phonograph is operated the traveling .drel-Iof'thephonograph. In this movement the slidable member 6 iscarrifed with the. ,reproducer and telescopes'within the tube 3- wlthout any-stress or strain other than the slight friction of-one body} moving. in a right line lon itudinally within the other. When arecor hasbeen playedand'it is desired i tomovetliei-reproducer back to-' its original ashion, so'as, to 'diseggage the feed-nut lower face of the bracket substantially strument and at the'bnd thereof opposite the the 7 be ishaped mouth piece, is connected to made; to rotate in a. horizontal plane as is common.

The 1 I e reproducer' is indicated by the. reference numeral 3 and the permanently tube which parallel-to the prises the bell shaped mouth-piece as desigbe supported from the phonograph cabinet by any convenientform of support, as well The member .for connecting the neck of the reproducer 5 to the cylindrical tube 3 is j designated-by the reference numeral 6. This hollow member is tapering in form and its smaller end-is prefera ly removably connectis preferably formed .uponthe member-6 and serves to, determine the position of the elbow -7 thereon. The larger end of the meman inwardly bent lipgor flange 9 which makes substantially a ball joint so that the member v G-m'ay' be moved to one sidevor upw-ardly as j shown in Fig. 2 without. disturbing the cominunication' e tween the member 6 and the carriage which bears the rep'roducer having the neck 5 moves transversely to themanosition the reproducer is raised in the usual from thefeed-scremand is'moved toward machine and subst ing 1 ducer, substantially as set forth.
