TALKING-MACHINE.

Application led .Tune 26,

To all w fiom t may concern:

Be it known that I, CLINTON E. WOODS,

- a citizen of the United States, residing at Vaterbury, in the county of New Haven and State of Connecticut, have invented a new andv useful Improvement in Talking-Machines, of which the following is a specification.

`- rlhis invention relates to talking-machines,- and particularly to the manner of mounting 'theAV Sound-'conveying Varm which supportsy the sound-boxof such machines, and to the manner of assembling certainV associated` elements of such machines.

Theprincipal object of this invention is to provide new and improved means for mounting the movable sound-conveying arm of a talking-machine so as to allow the usual freedom of movement ofthe sound-boxv carried by said arm and to cooperate with said 'arm inproviding a smooth, sound-tight and unobstructed passageway for sound. v

V .Another objectl of` this invention is to provide new Vand improved means for connecting ysaid movable arm to the stationary amplifying member or'horn, which means may 'be quickly and easily assembled and taken apart.

Infthe preferred embodiment of the inventionfthere is provided in a talking-machine the usual supporting deck `mounted in the cabinet in any suitable manner and having a -suitablylocated circular aperture extending 'conveying arm,there is 'therethrough to permit the passage of Sound from a'sound-conveying arm to an amplifying member or horn. To form the female member of a swivel joint for said soundprovided a flanged annular plate, of Which the face portion rests' flat upon and is supported by'isaid deck, and the Vflange portion projects down- `wardly through the aperture therein to form a tube. f The male member of said joint comrises a second annular late havino a tubul) p b larportion extending through said aperture, being journaled in the downwardly-projecting tube-portion of said first, annular plate and supported by the face portion thereof. Fromthe `upper face of said second plate, there rises a marginal flange whichvis turned inwardly at its upper end to form a lip to engage the collared base of the sound-conveying arm, which is secured thereto by a suitable hinge.

The invention is susceptible of embodiment in various forms, one of which, for the Specification of Letters Patent.

purpose of illustrating the invention, has been shown in the accompanying drawings, in which` Figure 1 is a plan view of a sound-box, sound-conveying arm and mounting therefor, in accordance with this invention; and Fig. 2 is aside elevation, partly in section, of the Supporting deck, Sound-conveying arm and associated parts of a talking-machine.

Referring now to Fig. 2, there is shown theusual supporting deck 1 mounted Vin any usual manner in the talking-machine. A turntable 2, carrying record-tablet 3, is also Shown. Suitably positioned with respect to the turntable, there is provided an aperture extending through the supporting deck l. vAn annular plate 4 rests on the upper face of thedeck, registering with the aperture therein,v and has a downwardly projecting 'cylindrical or tubular portion 5 fitting snugly within said aperture; l

` A second annular plate 7 rests freely upon 'said plate 4, andhas a downwardly-projecting tubular portion 6, fitting freely within of plate 7 there rises which is inturned to form a lip 9. The inner edge of the lip 9 is grooved so as to holda gasket 10 which may be of rubber or a marginal flange 8 any usual packing-materia A tubular sound-conveying arm 12 is provided at its base with a collar 11, which may be integral with the arm or may be secured thereto in .any suitable manner. The collar 11 isV fitted into and yieldingly engaged by the gasketed lip 9. A portion of the flange 8 and lip 9 is cut away to receive an ear 13 which may project from the rear of collar 11 as shown in Fig. 1 or from the front of said collar and is slidinofl en aUed by shoulders 14 of the cut-aivayy pogrtibn. A pin 15 passes through corresponding holes in the flange 8 and in the ear 13 to provide a sound-conveying horizontal axis, ear 13 and portion 8 forming arm 12 may be swung on a the pin 15,

together a` hinge.

Supported at the outer end of the soundconveying arm 12 in any suitable manner, as by an elbow 16, there is provided the usual or any desired form of sound-box 17, here shown as a convertible sound-box equipped with two Styli, one of which may be the usual reproducing-needle and the other a jewel-point, so that records of any type may From the face comprising the plate 7 which be played by a Simple adjustment of the sound-box.V

The sound-conveying arm 12 is allowed the necessary' range of movement toward Y and away'from the recordtablet by the hinge 13, the contacting of its base portion upon the plate 7 serving as a stop to limit its downward movement when there is no record tablet to receive the stylus, while its upward movement is limited by the pressure of the gasket 10 on the collar 11. v Freedom of movement for the arm 12 about a vertical axis is provided by the swivel joint bears on the plate 4, the tubular portion 6 of which is journaled in the tubular portion 5 thereof. In order to decrease the bearing surface of this swivel joint, the underside of the plate 7 may be countersunk and the inner side of the flange 5 may be countersunk as shown in Fig. 2. To limit the travel of the soundbox in a plane parallel to the record tablet,

' the outer edge of the plate 7 may bev recessed to form shoulders 18'which Aabut againsta suitable stop as the screw 19, which is set` in the plate 4.

To secure the neck 20 of the amplifying member or horn in its proper position relative to the deck 1, there is provided a flanged annular plate 23 which registers with the apertures in said deck, and theinner edge of which is countersunk to receive the base .of fthe tube 5 for' facility in assembling.y

To' secure the plates 4 and 23 to theV deck, there are provided screws 24 which pass through holes inthe deck, which register vwith corresponding countersunk holes in the yplate -neck 2O fits snugly within the iange 22 of 4 and threads in the plate 23. The

the plate 23 andv is secured thereto in any desiredv manner as by screws 21. The upper end of'fthe neck 20 is of the same internalV diameter as the tube 6 and is set so as to contact evenly with the lower end thereof,

thus providing a smooth passageway for` Y sound.

In assembling the mounting for the soundc'onveying members of the talking machine, the plate 4 is first set in place onthe Vdeck 1. The plate 23 to which the neck 20 is held secure is then fitted on the base of the tube 5. The plates 4 and 23 are then secured to they deck by the screws 24, adjustment for varying thickness of the deck 1 being allowed by reason ofthe space between the basel of the tube 5 and the face of the countersunk portion of the plate 23.' AThe soundconveying arm 1 2 is hlngedto the` plate 7,

Y an upwardly-extending portion o-said tubu- `ginal flange rising from Ysaid second plate .and inturned to loosely enc1rclesa`1dcollar and having a cutaway portion to receive saidY Y which is then journaled inthe tube 5. The stop 19 is then screwed inuntil its head rests on theplate 7 and-the assembling of the mountingis complete. 'While the details yof the preferred ernbodiment of the invention have been Vdescribed with much particularity, Vthe invention is not limited to the specific details shown since these maybe varied within the terms of the appendedA claims, without departing from the spirit of the invention.
