TALKING MACHINE.

'Application led May 6, 1925, Serial No. 28,444, and'in Great Britain May 14,1924.

This invention relates to improvements in talking machines and in particular to improved means of mounting a large diaphragm, adapted to play without a soun-d The object of the invention is to enable the diaphragm to be so mounted that it is easily handled for changing the reproducing needle and for inserting the needle in the sound line.

According ,to the invention a talking machine is provided in which a diaphragm of the type referred to above has the stylus holder mountedl at ornearto its edge, said diaphragm being' mounted to rock about a .point substantially diametrically opposite the stylus holder so that the stylus can move both transversely across the'record and vertically.

The diaphragm may be mounted tolie in any convenient plane during playing; for example it ma \lie in a plane inclined to that of the recordfor turntable.

In constructions of talking machine embodying' this invention it may be found advantageous to mount the diaphragm in such a' manner that it can' be moved, when notl in use, into a position substantially parallel with the record, so that the cabinet of the machine shall not require to be of unusual depth between the lid and the motor board.

The invention is illustrated by way of eX- ample in the accompanying drawings in which Fig. 1 is a side elevational view of a machine with the parts in the playing position. 85 Fig. 2 is a similar View to Fig. 1 but with the parts in the non-playing position.

. Fig. 3 is a rear elevational view ona larger scale showing the diaphragm carrying means.

Referring to the drawings, 1 is the dia- 4 phragm carried within a stiff holding rim 2,

said 'diaphragm and rim lying .during playing,'as will be seen from Fig. l, in a plane in- I clined to thatof the turntable 8. VThe stylus holder 4 is mounted on the front or lower end of the diaphragm holding rim 2 and is maintained in position by bolts or the like passed through the rim 2, and a member 5 eX- tending from the centre of the spider v6 and o secured to said stylus hol-der 4 by screws 7 or other suitable means. Upon the rear arms 8 of the spider is mounted, by means of bolts or the like, a flat plate 9 and to this plate is needle across the record during playing.rr

The pillar `17 is rigidly mounted upon a plate 18 adapted to rock about a horizontal aXls determined by bearings formed by screws 19 and lock-nuts 20 carried in lugs 21 upstanding from a plate 22 screwed to the motor board 23,-which engage in recesses formed in the sides of the plate 18. ALugs 24 are provided on the plate 18 to arrest the rotation of the latter in one direction (clockwise in Figs. 1 and 2) by engagement with the plate 22. Movement in the opposite direction is limited by the engagement of the end face 25of the plate 18 with an adjustable stop screw 26 projecting upwardly from the base plate 22. A strong leaf spring 31 is provided on the base plate 22 which serves to maintain the plate 18 and the parts which are carried thereby, in either of the two alternative po-` sitions; i.-e. in the playing position shown in Fig. 1 by upward pressure against the under surface of the plate 18 and in the non-playing position shown in Fig. 2 by upward pressure against the forward end 25 of plate 18. The front end ofthe lug 24 on the same side as screw '26 is cut awayas shown at 27 so that it shall not foul said screw 26 during movement. 28 is a collar, adjustable longitudinally of the rod 16 and carrying a spring 29 which engages with an extension 30 of plate 9 bolted to spider arms 8 to take a portion of the weight which would otherwise rest, through the stylus, upon the record.

The weight with which the stylus restsupon the record can be v aried at will by moving the collar 28 up or Idown the rod 16.

During playing, up and down movement of the diaphragm, necessitated, for example, by a turntable or record -not rotating in al true horizontal plane, takes place about the horizontal axis determined by bearing screws 13 and rod 15, while the movement of the stylus across the record is permitted byrod' 16 rotating about the vertical pillar 17.

, When it is desired to move the diaphragm from the position of playing as shownl in Fig.l 1, the diaphragm is pulled vto the left and the rod 16, pillar 17, and plate 22 are 4moved about the horizontal axis, formed by pins 19, against the pressure of spring 31, untilthe position shown in Fig. 2 is reached; This arrangement obviously requires much less depth between thefturntable and the top of the lid of themachine when closed than would be the case if the diaphragm remained in the raised playing position.

I claim: v

1. In a talking machine of the large diaphragmtype wherein a record turntable is mounted above a motor board, a supporting spider for the diaphragm, a stylus carried by the spider-'and operatively connected to the diaphragm, and means coacting with said stylus to support said diaphragm Jfor playing in a plane inclined with respect to said. I

turntable, said means including a member pivoted to tlievmotor board at one side of said turntable, and means, permitting movement of the diaphragm in vertical and horizontal planes, -mounted on said member and secured to said spider at a point substantially diametrically opposite said stylus.

2. In a talking machine of the large diaphragm type wherein a record turntable-ius mounted above a motor board, a supporting spider for the diaphragm, a stylus carried by the spider and operatively .connected to the diaphragm, and means coacting with s aid stylus to support said diaphragm for playing in a plane inclined with respect to said-turntable, said means including a member pivoted to the motor board at one side of the turn?l in an inclined playing position relative to.

the turntable, said means including telescoping members, and means pivotally connecting one of said members'to the motor board to permit movement of the diaphragm to nonplaying position substantially parallel to the turntable. f

4. A talking machine of the large diaphragm type wherein a turntable is rotatably mounted above a motor board, a stylusl vmounted adjacent the edge of the diaphragm and operatively connected to the latter, means coacting with thestylus to support said diaphragm for playing in a plane inclined with p respect to said turntable and said means including a normally stationary pillar'secured to the motor board at one side of the turn- 5. In a talking machine of the large diaphragm type wherein a record turntable is mounted above a motor board, a mounting for the diaphragm comprising a plate secured to the motor'board atone side of the turntable, a pillar pivotally secured to said plate and adapted to be moved to a position substantially parallel with the motor board, means yiedingly maintaining said 'pillar in an upright position, a rod pivotally mounted on said pillar, means operatively connecting said diaphragm and rod, and yielding means carried by the rod. adapted to engage said lastnamed means when the diaphragm occupiesl a playing position.

6. In a talking machine of the large diaphragm type -wherein a record turntable* is mounted above a motor board, a mounting for said diaphragm comprising a plate 'secured to the motor board at one side of the turntable, a pillar pivotally secured to said plate, means for yieldingly maintaining said pillar in'a substantially vertical position 0r 4in a position substantially parallel with the motor board and means mounted on the pillar and secured to the diaphragm for permitting movement of the diaphragm in vertical and horizontal planes. Y

7. A mounting for a talking machine diaphragm comprising a diaphragm spider, a

pivotally mounted supporting pillar, means connecting said spider and pillar permitting movement of the diaphragm in vertical and horizontal planes, and a yielding element adjustably secured to said last named means and normally having engagement with said spider, said yielding element being adapted to support said lastnamed means when the diaphragm is moved to non-playing position.

' 8. In a talking machine of tlie large diaphragm type wherein a turntable is rotatably mounted above a motor board, a normally upright pillar pivotally secured to the motor board at one side'of the turntable, means including a spider 'for pivotally securing fthe diaphragm to said pillar and adjustable means including a resilient member supported by the pillar and having abutting engagement with the spider when the diaphragm is in playing position, said resilient means being adapted to engage sald motor board to yieldingly support said pillar when the diaphragm is moved to a position substantially parallel with the motor board. 5

In testimony whereof I have signed my name to this specification. v
