JERSEY CAMDEN, NEW JERSEY,

A CORPORATION OF TALKING mcnmn' Application filed July 28, 1925,

This invention relates to improvements in talking machines of the type embodying a sound reproducer in the form of a large diaphragm carried at'the end of a member capable of swinging across the record, and in particular to an improved method of mounting the diaphragm so that it will play in a position inclined or at right angles to the plane of the record and when not in use can be folded down to lie approximately parallel with the record.

The principal object of the invention is provide means whereby when the diaphragm is folded down into the horizontal position its lower edge, ,at which the stylus bar is pivoted, is moved forward, or advanced in front of the position which itoccupies during playing, with the consequence that the whole of the diaphragm when lowered can be brought into the space available in a talking machine cabinet bonstructed for the ordinary sound arm machine of to-day even though the diameter of the large diaphragm is greater than the distance from the sound arm pivot of the ordinary machine to the turntable centre. In the ordinary machine of to-day the sound arm is pivoted as a rule quite close to the back of the cabinet and the new attachment may be fixed in precisely the same position as at present occupied by the pivoted sound arm.

According talking machine of the type referred to above is provided in which when the diaphragm is moved on the swinging supporting member from its playing position to a non-playing position substantially parallel with the rec 0rd, the diaphragn is also moved bodily in a direction away from the axis of rotation of the swinging member and towards the side of the machine remote from the said axis of rotation.

In the preferred construction, the diaphragm is mounted to rotate about a horizontal axis carried by a member which is itself carried on the member in such amnnnerastobecapableofrotationabout a horizontal axis, the movements of the diaabolltthese two horizontal axes taky and under the consong to the invention therefore, a

trol of a. rod pivotally connected at or near the edge of the diaphragm and sliding in friction bearings in the swinging member and in a direction substantially parallel to the longitudinal axis thereof The invention is illustrated by way ofexample in the accompanying drawings in which Fig. 1 is a side elevation of the apparatus the parts being showniin the playing position.

Fig. 2 is a similar view to Fig. 1 with the parts in the non-playing position. Fig; 3 is a plan view of the diaphragm carrying means the diaphragm itself being omitted for the sake of clearness and Fi 4 is a rear elevation of a part of the diap ragm showing the method of connection to the carrying means.

I Referring to the drawings, 1 is a member adapted to rotate about a vertical axis determined by bearings formed in a member 2 screwed to the motor board 3. The member 1 is furnished with a short upwardly extend-. ing arm 4 having a wide outer end 5. This 7 wide end 5 extends between a pair of lugs 6 formed on the end of a long member 7 adapted to swing across the record 8 as the part 1 rotates in its bearings.

The connection of lugs '6 and wide end 5 is effected by passin a pin 9 through holes formed therein'an securing itb nuts 10 at the ends so that member 7 is capa le of being swung upwards about pin 9. A spring butter 11 is provided beneath the member 7, said spring pressed plunger 12 moving in a 19 and engaging w1th a stud Ben the underside of the arm 4 so that only a portion of the weight of the parts pivoted on the pin 9 rems'on the record. At the outer end of-the arm 7 are formed lugs 14 between which is pivoted one side 15 of a 7 plate 16, the connection being by means of screwsflpassedthroughthelugslimdinto thickened parts of the plate 15. The other sideflfioftheplate 16carrieslugs2 1 (Fig. 3) to Ihidl the diaphragm 22 is pivotally by means of screws 23 spa-tutu in brackets M secured to tbedmphragllhaldhgringligilmd2.

on the bloc In the construction illustrated the diaphragm plays in a osition at right angles to the record and W en in. this osition the plate 16 slopes upwardly at an 0 tuse angle from the member 7 towards the diaphragm.

The line'through screws 23 about which the diaphragm ivots is at a short distance above the lower'e ge of the diaphragm, and pivot the holding ring, or preferably to the block 25 which carries the stylus holder 26 and is itself connected to the holding ring, is a small bracket 27 to which is attached a rod28 adapted to slide smoothly in friction bearings 29, 30, mounted on the member 7. When the diaphragm is raised into the playing position the bracket 27 forms a stop limiting the rearward movement of the od 28, the block 25 engaging with the inner ace 27 of bracket; 27 and thereby determining the fully raised position of the diaphragm. When the diaphra m-is folded down parallel with the rec'- ord t e rod 28 is drawn forward in its friction bearin s 29 and 30, the bracket 27 ivots l 25, and the diaphragm an plate 16 at the same time moveabout the bearings 23 and 17, the plate 16 gradually assuming an almost horizontal position as shown in Fig. 2.

I The position of axis 17-17 being fixed with regard to the member 7 the axis 23-23 is moved through an arc of a circle and when the diaphragm is turned down occupies a position corresponding to the point shown in Fig. 2 which is at a greater distance from the axis of rotation of member 7 than when in the position shown in Fig. 1, The diaphragm 22 is therefore moved bodily to the tical right in Figs. 1 and 2 and the top 31 of the diaphragm in the lowered osition does not project to the left beyond t e member 2.

The bearings for the rod 28 are in the form-- of sleeves 32 and 33 mounted in the member 7 and within which are provided felt pack-' ings 34 to ensure smooth movement of the rod. Between the sleeves 32, 33 is a recess in which rests the spider'35 of the diaphragm when in thelowered osition. In the underside of the rod 28 is ormed a notch 36 which when the diaphragm is in the raised position engages with a bent spring 37, so that the diaphragm can only be moved from the verposition by the exertion of a certain force.
