OWEN JOHN PITTS CBIOK, OF LONDON, ENGLAND, ASSIGNOR '10' VICTOR TALKING MACHINE COMPANY, A. CORPORATION OF NEW JERSEY rmo mncnmn Application filed May 10, 1930, Serial No. 451,428, and in Great Britain June 12, 1929.

This invention relates to improved means for holding disc talking machine records and in particular to improved means for holding disc records by engagement with their central apertures.

The device forming the subject of the invention is intended primarily for use with the record conveying mechanism of a magazine talking machine whereby a series of records are fed singly and in succession from a magazine to the playing position on V the turntable, although it is to be understood that it may also be used for other purposes, such as retaining a record in position on the turntable of a talking machine. The record holding device according to the present invention comprises a member having a recess formed in it and adapted to be inserted in the central aperture in the record, and a member movable with regard to therecessed member and adapted to be inserted with the recessed member in the central aperture in the record and after insertion to move said record with regard to the recessed member to engage a part of the edge of the central aperture ofthe record within the recess. 7 s

The invention is illustrated by way of example in the accompanying drawings as applied to a swinging conveyor arm adapted to transfer records singly from a pile in a magazine to the playing position on the turntable. j v p In the drawings 7 Fig. 1 is a view in sectional elevation of the conveyor arm and record holdin device with the parts in the normal position.

Fig. 2 is a view in elevation of the record holding device about to engage the uppermost record of a pile.

Fig. 3 is a view in elevation showin a record completely engaged by the holding device. v

Fig. '4 is a; view in elevation showing the parts in the positions they take up torelease the record from the holding device.

Fig. 5 is a view similar to Fig, 1 illus-' .trating hand controlled means for operating "the holding device.

' Referringto thedrawings (Figs. 1 and 5 an arm 1 in the form of an inverted channel shaped metal pressing is fixedly mounted at the upper end of a post 2 which is itself arranged for movement both vertically and horizontally in known manner in a suitable hearing sleeve 3.

At the free end of the arm 1 is fixedly secured a downwardly extending hollow rod 4 the external diameter of the lower end of which is such that it can enter within the central apertureof a record. Also at the end of the arm 1 is fixedly mounted a downwardly extending bell-shaped abutment member 5 surrounding the hollow rod 4. For the purpose of mounting the hollow rod 4 and the abutment member 5 in position on the arm 1 the rod 4 is provided with a shoulder 6 near its upper end and the part of the rod above the shoulder is screw threaded externally. This screw threaded part of the rod 4 is passed through an aperture 7 in the bottom ot the abutment memberv 5 and a similar aperture 8 in the end of the arm and fixing of the rod 4 and abutment member 5 in position is effected by means of a nut 9.

The rod 4, near its lower end and on the side towards the post 2 is provided with a recess 10 of a vertical width slightly greater than the thickness of a record and the upper edge of this recess 10 lies in substantially the planerof the lower'edge ll of the abutment member 5.

A pin 12 is mounted for sliding movements within-the interior of rod 4, said pin being provided with an enlarged head 13 housed within an enlarged portion 14 at the upper end of the passage through the rod 4 whereby the downward movement of the pin 12 islimited.

In the rod 4 and the pin 12 near their lower ends are formed

slots

33 and 34 re-.

Spectivly, these slots lying in alig1 :1ment with one another in theT'central vertical plane of the arm, so that the slot 33 in rod 4 bisects the recess 10. The

slots

33 and 34 together form a housing for the hooked shaped end 15 of -a stiff wire spring 16 anchored at its other end in a slot 17 in the l shoulder 6 on rod 4 by means of an anchoring screw 18.

The width of the hook 15 is substantially equal to the diameter of the rod 4 and in its normal or rest position projects in part from the slot 33 at the side of rod 4 away from recess 10 as shown in Fig. 1. The hook 15 storing force of the spring 16 to be obtained.

. A. fixed pin 21 is arranged to lie transversely of the slot 34 in sliding pin 12 and in a position where'it can engage the bent portion 22 of the spring 16 adjacent the hook 15 when the sliding pin 12 is suitably moved.

In operation, to feed a record 35 from the top of a centrally aligned pile (Fig. 2) the arm 1 is swung horizontally and lowered in known manner to engage the lower end of the rod 4 in the central aperturesof the records at the top of the pile, the record centering pin 36, if used, being yieldingly mounted to recede before the downward thrust by the end of pin 12. As the end of the rod enters the aperture in the uppermost record, the hook 15 is caused, by engagement with the edge of the aperture, to recede into the

slots

33 and 34 in the manner shown in Fig. 2, the spring 16 being thereby placed under tension. When however, the recess 10 in the rod 4 registers with the wall of the aperture in the top record the pressure of spring 16 is exerted to move that recordto the left in Fig. 2 and the record is now firmly engaged in the recess bythe hook 15.

It will be noted that no sliding movement of the record next to the uppermost can take place asthe top record slides over it, since the unrecessed lower extremity of the rod 4 is engaged within the central aperture of that record.

The uppermost record now held in recess 10 by hook 15 lies in contact with or close to the edge 11 of the abutment member 5, so that no tipping movements of the record can take place as the arm 1 is raised and swung to transfer the record to the turntable or playing position. v

. The arm 1 having reached the position where the record is over the turntable, said arm is lowered in known manner and during the lowering movement the transferred record is released from the rod 4 and permitted to fall on the turntable. The release of the record is effected as follows:

As the arm 1 is lowered, the lower end of pin 12 engages with the upper end of the central turntable spindle. I movement of arm 1 therefore, results in the pin 12 being thrust longitudinally of the rod 4. By this means the transverse pin 21 is caused to engage the bent portion 22 of spring 16 in such a manner that the spring is deflected and the hook again caused to Withdraw into the

slots

33 and 34, at the same time pushing against the wall of the central aperture in the record and removing it from recess 10. The record thereupon slides off" the rod 4, falling on to the turntable with its central aperture over the turntable spindle, in which position it is ready for playing.

Means are also provided to permit a record held on rod 4 to be removed by hand.

F or this purpose there is provided a lever 23 (Figs. 1 and 5) in the form of a fiat plate, one end 24 of which contacts with the underside of the arm 1, while the other end 25 projects through a slot in the enlarged part 6 of the rod 4 and into a recess 26 formed in the enlarged upper end of pin 12. The size of recess 26' is such that the pin 12 is capable of the movementsnecessary for the automatic operation described above independently of lever 23. The lever 23 intermediate its length is provided with a finger knob 27 and the part of the lever 23 abovethe knob engages within a slot arranged diametrically of a short hollow boss 28 fixedly mounted on the under side of the arm 1 by means of a screw 31. A transverse fixed pin 29 extends across the slot in member 28 and through an elongated slot 30 in the lever 23 to, retain the latter in position while permitting limited movements thereto about the fulcrum formed at the point of contact of the end 24 of the lever with the underside of arm 1.

It will readily be seen that by grasping the arm 1 and lifting the kn0b.27, the pin 12 can be raised within rod 4 to move hook Further downward 4 15 in the manner described above to disengage a record from recess 10.
