yprinciple oftheinv'ention being herein ex-fV plainecland the best mode in which' I have 10 of Which the' ollowing'i's aspecitication, the

contemplated applying that'principle, so as to distinguishitfroinother inventions'.

` .The present `1"n`vention relates in 'general to talking machines, and is intendedparticu- ,larly to provide protection forthe delicate mechanismemployed vinsnch machines.

The'general objectof the invention, therefore, is to provide a protective inclosuie for talking 4machines which Will still allow the swinging movement of the tone-arm, and

which will also alloii/ easy access" to the reproducing mechanismlv Y Other advantages 'of the invention will appear irnr` the I'detailed descrip tion*y Wh ich follows.

To the accomplishmentofthese and related ends, said invention, then, consists of the means .hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms inl Whichrthe principle of the invention may be used` In said annexed drawings z--Fignre 1 is a side elevation of a machine embodying my invention, certain parts being diagrammatically shown; Fig. 2 is a top plan, certain parts being diagrammatically shown in alternative positions; Fig. 3 is a front ele fz tion, and F ig. 4 is a section on the line A A of Fig. 2.

In the drawing I have diagrammatically shown the inclosnre 1, which incloses the motor for rotating the record disk 2. I have furthermore shown the record disk 2, the

sound reprodncer 3. the sound conveying means 4, and the horn 5, diagrammatically,

as these do not enter into the present invcntion but are of any usual type. IHerea'lter I shall refer to the record 2 and the reproducer 3 as the sound reproducing meehanism, the sound conveyor or ,tone-arm 4 being supported so as to permit itsforivard end to swing oversaid record, while its rear vend wnUGENnA hnnnniapnn offene g "Iheinyention proper, comprises an inclosing box, orv'cabinet which is adapted to rest in )on the box ,lithat forms the inclosure 'for thetalki'ng machine, proper. This `box, includes aV 4relativelyfixedpart 7 having a skeleton Ab ase, that` isy adapted to removably rest `upon the4 topv edge of the box 1 inclesing the ,talkingA machine; Such box-part-7 is oponin froiiff and to its respective lateral edges, are pivoted tnioslmilar parts S and 9,

these partsbeingsecnred to the .fixed part 7 by lvertical h1 i'1`g'es 1'0 and 11respectivcly.

yThe parts 8 and 91nay be provided with 'suitable knobs y or handles.

catches, suclias :12,5it'or retaining them in closed position, in which position, they. together with' the fixed part '7, completely 'inclose the top ofjb'ox l with the recordQ and the-Forward.portion of the sound conveyer 4.

The rear Wall ofthe box is provided with 'an elongated opening through' which the 'tone arm' extends. Ilo the ,rear Wall ofk the box is secured ya second-box which' is consti- O tntedpftwo separate parts M and 1 5 which are hinged lrespectively'to the rear Wall on vertical hinges' 1G and 17. These parts are providedv ivith iinperforate bottoms but their top Walls are formed withcomplementary semi-circular openings 18 and 19, While their rear Walls are formed with substantially quarterfcylindrical recesses 2O and Q1. The usual bracket 2Q is secured to the inclosure 1,

and has a vertical post 25 which tits Within the recess 20--21, and is further provided with an arm Q3 Which forms a bearing for the tone-arm and amplifier. The tone-arm is also provided belonT this bearing with a. pivotal post 24, that is supported on said bracket 22.

In use, the double box is placed firmly upon the inclosure 1 for the motor. The tone-arm extends rearwardly through the apertured rear wall of one box, upwardly through the bearing provided by the bracket, the amplifier thence l'nojccting through the opening provided by the two complementary parts of the second box. The complementary pivoted parts ot' the larger box may be swung open to each side so that the sound reproducing mechanism is completely accessible. After a record has been secured in place and the stylus properly positioned, the box is closed, and con- "I atented Apr. 21, 1914..4

and with spring,

sequently the vdelicate parts of the reproducing mechanism are amply protected, and at the same time the harsh mechanical sound of the mechanism is deadened or destroyed.

The amplifier has its usual support from, and bearingin, the bracket. This part of the mechanism is, protected by the complementary pivoted parts which form what may be termed the rear box. It will be noted that this rear box prevents any dirt from getting into the front box through the opening necessary for the movement of the amplifier. At the same time, however, the two parts of the rear box may be swung wide open to each side so that the parts are completely exposed if desired. By the use of' my invention, then, all the delicate mechanism which forms a talking machine may be completely protected from dirt and dust and at the same time the protective in- 'closure destroys to a large extent, the mechanical sounds which are so undesirable in' machines vof this class.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed,

I therefore particularly point out and distinctly claim as my invent-ion 1. A cabinet for a talking machine of the kind having an amplifier and a swinging sound conveyor supported on a bracket projecting rearwardly from the box inclosiug said machine, lsaid cabinet comprising a relatively fixed part open in front and having a skeleton base adapted to removably rest upon the top edge of said box said fixed part also having ahole in its rear Wall for .being adapted to completely inclose the top said sound conveyor; two similar parts vertically pivoted to the respective lateral edges of said relatively xed part, said parts of said box; and a second box secured to said rear wall, said second box including two parts pivotedl to said wall on vertical axes and formed with complementary, substantially seinrcircular openings in their top walls, so as to be adapted to inclose the rear portion of said sound conveyer without interfering with its movement.

2. A cabinet for a talking machine of the kind having an amplifier and a swinging sound conveyor supported on a bracket pro! jecting rearwardly from the box inclosing said machine, said cabinet comprising a relatively fixed part open in front and having a skeleton base adapted to removably rest upon the top edge of said box said fixed part also having a hole in its rear wall for said sound conveyor; two similar parts vertically pivoted to the respective lateral edges ot said relatively fixed part, said parts being adapted to completely inclose the top of said box; and a second box secured to said rear wall, said second box including two parts pivoted to said wall on vertical axes and formed with complementary, substantially quarter-cylindrical recesses in -the outer sides of their rear walls, so as to be adapted to inclose the rear port-ion of said sound conveyer without interfering with its movement.

Signed by me this 27th day of August, 1910.
