T 0 all 'whom it may concern: Beit known that I, DELos HOLDEN, a citizen of the United States, and a resident of following is a description.'

`My invention relates to phonographs o r talking machines and more particularly. to phonographs or talking machines of. the cabinet type having a movable cover which contains the usual horn or sound amplifier.

The principal object of my invention is to provide an improved device of this character having one or more covers which may be opened or closed without forming a break in or interrupting the continuity or varying',

the length of the sound conveying passage or passages through which the Sound Waves from the reproducer pass to the atmosphere, the generic invention and one species thereof being claimed in an application, Serial No. 763,702 filed by me on' April 26, 1913 and entitled phonographs or talking machines. In this application I shall describe and claim another species of the invention.

In order that the invention `Irl-aye be more' clearly understood, attention is hereby directed to the accompanying drawing forming a'part of this specification and in Figure 1 is a view partly 'in vertical Vsection and 'partly in elevation showingv a talkiing machine embodying a form of..my invention comprising a plurality of covers and amplifiers, the covers being shown in open position in dotted lines; Fig. 2: is a view of the same partly in plan and partly 'in hori- 1 zontal section; and Fig. 3 is a view similar to Fig. 2 of a talking machine containing another embodiment of lily invention.

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

Referring to the drawing and more particularly to Figs. 1 and 2 thereof, the cabinet shown comprises -a base or body portion 1 and hollow covers 2 pivotally'supported in' a manner hereinafter more fully described. `A horizontal partition plate or other similar support 3 extends across and is secured in any suitable manner to the top'of the raten-tee Een. i, raie.,

body portion of the cabinet, the'partition plate supporting on its lower Side a casing 4 which incloses Ya motor (not shown) for rotating vthe turntable or support 5 upon which the sound record 6 to be reproduced is sound conveying armrS which isprovided at its rear with a downwardly extending portion communicating with andlpivotally supported by 'a tubular sound conveying 'member 9. The sound conveying member 9- is stationary and may besecured to the cabinet in any suitable Way, as by means of 'brackets 10. form of my invention shown in Figs. 1 and 2, extends transversely of the cabinet from Vone side to the other and is preferably of increasing cross section from the point at which the sound waves from the reproducer are discharged into the same bythe .arm 8 The said member 9, in the I toward its opposite ends at the sides of the W5 cabinet. The ends of the sound conveying member 9 are provided with forwardly extending outlet portions 11, the axes of which are parallel and are located at ,the intersection of the top surface of the support 3 and the outer surfaces of the side walls of the cabinet. Each of the covers Shown in Figs. 1 and 2 comprises aside wall 12, a rear wall 13, and a top wall 14, the inner edges of the top and rear Walls of one cover being adapted to contact with the corresponding edges of the top and rear walls of the other cover when the covers are closed,'as shown axial alinement with one of the portions 11 .of the sound conveyer 9. The sound conveyers are so connected to the parts 11 as to permit ralsmg or lowering of the coversa-nd -the amplifiers connected thereto without forming a. break in or interrupting the continuity or varying the length of the sound passage at the points where the Same are connected. Each part 11, as shown, is provided with aportion 16 .itting within the smaller end of the amplifier with which it communiioo cates, the amplifier bearing against a circular collar 17 on the part 11. A rod 18 Vhaving headed ends bearing respectively against the rear end of the part 11 and a bracket 19 in the amplifier serves to hold each amplifier in proper position with respect to the sound .and amplifiers shown in Figs. 1 and 2, and in that the stationary sound conveying member,9 with which the arm 8 communicates extends only to one side`of the cabinet, the

connection of the same with the sound amplifier being identical with that disclosed vfor each amplifier in Figs. 1 and 2. The single cover of the device disclosed in Fig. 3

will, of course, have two side walls, whereas the covers of the device of Figs.` 1 and-2 have but a single side wall.

Inboth forms of the invention herein disclosed, each cover and the sound conveyer movable therewith vare mounted for l pivotal movement about the same horizontal axis, which latter coincideswith the ceny ter or axis of the Itubular member X11 and the smaller endof the amplifier and with the axis of the rod 18. There is a continuous sound conveyer of fixed or-uniform length extending from the reproducer to 'the exit of the amplifier regardless of the vposition of the cover or covers, the amplification due tothe tapering of the soundconduit beginning at a Ipoint adjacent the reproducer arid i continuing gradually to the exit of the sound conveyen The reproducer and the record 'support are adapted to remain in operative relation to each other regardless of the p0- sition` of the cover. l Itis understood Ithat my invention is not limited to the precise apparatus shown, but

maybe varied within the scope of the appended claims without departing from the spirit of my invention.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is as follows:
