, cession and to feed them from a magazine to Cab the playing position, and in some cases the transferring device may also be utilized to remove played records trom the playing position and to deposit them in a suitable receptacle or to reverse the record preparatory to its being returned to the playing position.

The present invention is direct-ed to providing improved means for effecting engagement between a transferring device and a record.

According to the present invention a record transferring device is provided with means adapted to engage the aperture at the centre of the record disc and a point on 'the edge of the record, so that the record isy gripped between its centre and its edge.

The invention is illustrated by way of example in the accompanying drawings as applied to a talking machine having a-record conveyor arranged to swing about a vertical axis.

In the drawings Fig. 1 is a side elevation partly in section of one construction of record conveyor embodying the invention, a record being shown engaged therewith.

Fig. 2 is a plan view of Fig. 1.

Fig. 3 is a plan view similar to Fig. 2

but with the parts moved to release record from the conveyor.

Fig. et is an underside plan view of 'an alternative construction with a record in the engaged position. y

Figs. 5, 6 and 'i' are sectional side elevations oi the'construction shown in Fig. 4, but with the parts in dierent positions.

Fig. 8 is an enlarged sectional view ot a part of the mechanism. 1

Referring to Figs. 1, 2 and 3 of the draw.Y ings, a tapering arm 1 is connected rigidly at its widest end with a hollow vertical post the ords in a magazine P(not shown) and a posi tion over the turntable, and to move said arm l vertically whenv in either of those positions. I

At the free or narrow end of the arm l is fixed a downwardly extending pin le of a size such as is capable of passing into the central aperture of a record. The pin t is provided with an inclined shoulder 5, so that an annular depression is formed between said shoulder and the under surface of the arm 1. rlhe lower end ot the pin 4 is tapered to facilitate entry into the central aperture of a record.

Beneath the other end of the arm l is mounted a plate-like member 6, this member being connected with the arm 1 by means of headed pins 7 which extend through and slide in a longitudinal slot 8 formed in the arm 1.

The plate 6 is provided on its upper surface with a pin 9 which extends upwardly through the slot 8 in arm l, and a spiral tension spring l() is connected between the pin 9 and a luv il extending upwardly from the free end of tie arm l, this spring tend ing to draw the sliding plate towards the free end of the arm. Il "he thickness oi' the sliding plate 6 is substantialiy equal to or Aslightly greater than the thickness of a record to be conveyed and the edge 12 of the plate towards the free end of theI arm is slightly curved, the curve being struck subof the pin 4. lThe curved edge 12 isalso bevelled on the upper side as shown in Fig. l.

Wit-hin the interior 'of the hollow post 2 is provided aspindle 13 capable of rotation within the post 2. The spindle 13 at its upper end extends through the arm l and to the upper end, is rigidly secured a plate la having a part l5 extending radially from the spindle 13. The part 15 carries a in 16 which serves for the pivotal conneetlonl stantially about an axis coincident with that of the plate 14 with a slotted link 17, the

slot of which engages over the pin 9 extendin upwards from the plate 6.

n transferring records singly from the top of a pile in a magazine to the playing position, the arm'1 is moved in known manner intola position over the pile of records. At this point the spindle 13, plate 14 and link 17 occupy the positions, with regard to arm 1, indicated in Fig. 3, and the plate 6 is drawn awa-y from the free end of the arm 1 against the sprin 10 by virtue of the connection between t e slot in link 17 and pin 9.

The post 2, arm 1 and parts supported thereby are now lowered in a manner similar to that shown in British Patent 291,480 until the pin 4 engages in the central apertures of the uppermost records of the pile. The spindle 13 is now rotated through .any convenient meas such as a cam (not shown) drivenby the vmachine motor and the link 17 moves `to permit the sliding plate 6 to be drawn towards the free end of the arm 1 under the pull of the spring 10. The!l movement of plate 6 continues until its bevelled edge 12 engages the edge of the uppermost record of the pile, whereupon that record is caused to move into the position indicated in Figs. 1 and 3, where the edge of the-central aperture is engaged in the annular de ression above shoulder 5. When this positlon is reached movement of plate 6 ceases but link 17 is permitted to continue its movement as spindle 13 rotates by virtue of its pin and slot connection with p ate 6.

lt will be readily understood that by this arrangement the member 6 will move along the arm through distances determined by the size of the top record 'and that records of various sizes can thereore be engaged.

The record is. now gripped between its central aperture and a point on its edge by the pin y4 and the sliding member 6.

The arm 1 is next raised to lift the uppermost record from the pile, and then swung to a position over the turntable and lowered until the end of pin 4 engages or is close to the upper end of the turntable spindle. The spindle 13 is again rotated in post 2 until the end of the slot in link 17 engages pin 9 to draw member 6 away from the edge of -the record engaged thereby, whereupon the record is permitted to slide oil' the shoulder 5 and to fall by gravity on to the turntable for playing.

The pile of records in the magazine may be centralized in known manner by a vertical spindle passing through their central apertures and this spindle may beso mounted as to be capable of being yieldably depressed by engagement with the pin' 4 as the arm 1 is lowered over the pile, to permit said pin to` enter the central apertures.

Similarly, when the device is required to remove a record from the turntable, a yieldably mounted turntable spindle may be used, the spindle being adapted to be depressed from the central aperture in the record when the pin 4 on the arm 1 engages the spindle .upon entering the record aperture.

Figs. 47 illustrate an alternative arrangement according to the invention.

In the construction therein illustrated, an arm 18 having a downwardly extending flange 19 at its edge is secured at the upper end of a hollow post 20 mounted as in the previously described arrangement for longitudinal and rotational movenients. At the outer end of the arm 18 is ixedly mounted a boss 24 from the centre of which a pin 21 extends downwardly. This in has a cutaway portion 22 of a width w ich is slightly greater than the thickness of a record. This cutaway portion leaves a slo in shoulder 23 on the side of pin 21 towards t e post 20. At a point about mid-way of the length of the arm 18 and between the side flanges is rigidly-fixed a sto 25, formed by a piece of bent metal rivete to the arm 18, and this stop has a plane surface which projects just below the level of the flanges 19.

Beneath the arm 18 and on the side of the stop towards the post 20 -is provided a plate 26 on the upper surface of which are supported two short pillars 27, 28, which project through elongated slots 29 formed in the arm 18.

The pillars 27 28 at their upper ends are fixedly connected by screws 30 with a plate 31 above the arm 18and the arrangement is such that plates 26 and 31 are capable of movement together both longitudinally 'of and towards and away from the arm 18.

Above the arm 18 a bell crank lever 32 is mounted for pivotal movements about an axis. pin 33 carried in fixed lugs 34 fixed to the arm 18. nected to a link 35 which in turn is connected -with a lu 36 mounted rigidly on the u per surface o -plate 31. The other arm o the r One arm of the lever 32 is con-l are caused to move longitudinally of the arm 18, the pillars 27 28 sliding in the slots 29. The arrangement, however, is such thatL as rod 38 approaches its lowermost position,

pillar 28 engages with the end of its slot 29,

and the plates 26 and 31 are tilted into the position indicated in Fig. 5'.

A plate member 39 1s attached to the underside of the' plate 26, for limited rocking movement with respect thereto, by means of -a pivot pin 40 which 1s Journaled in a' pair of ears or lugs 41 formed on and depending from the side edges of the plate 26 and suitable apertures formed in the' the other end of member 39 engages .the`

surface of plate 26 so that the edge 43 when l in its lowered position projects beneath the stop 25 a distance which is substantially equal to the thickness of a record.

A plurality of hook members 46 are formed on the platemember 39, adjacent the lug or ear 45, which project below the stop member 25 a distance substantially equal tothe thickness of a record when the member 39 is in horizontal position.

In the position of member 39 indicated in Fig. 5 where no record is engaged, the edge 43 and the hooks 46 are respectively at distances from the pin 21 which are slightly greater than the radiiof 10 and 12 inch records.

All the parts above the arm may be enclosed as indicated in the drawings, by ahood or cover 47.

The operation of this device is as lows:

Assuming the arm 18 to be in position over a. pile of records, of which the upperfolmost is of say 1.0 diametenand restingthereon with pin 21 engaged in the central aperture of the uppermost record and the stop 25 resting on the surface of that record.

YTo take up the uppermost record, the rod 38 is moved upwardly within the hollow post 20 in any convenient manner to rock the bell crank lever from the position indicated in Fig. 5. As a consequence plates 26and 31 move until plate 31 rests on the arm 18 and the end 43 of member-39 drops below .26 and 31 moved toward the pin 21, the endv stop 25. Further movement of rod 38 causes the plates 26 and 31 and member 39 carried thereby to move towards the free end of the arm 18until the end 43 of member 39 engages the edge of the uppermost record. The latter is thereupon caused to slide to a limited extent until the edge of its central aperture engages with the cutaway part. 22 of pin 21 above shoulder 23. The record is now held against the arm 18, between pin 21 and member 39 in the manner indicated in Fig. 6, and the arm can now be raised and swung, together with the record, by rotating post 29 in any convenient manner, to a position over the turntable and lowered to place the record on the turntable. The record is then freed from the conveyor arm 18 by moving the rod 38 downward within post 20, whereupon plates- 26 and 3l and member 39 are drawn to the right in Fig. 6 to disengage the edge 43 from the edge of the record, so that the latter can fall from the sloping shoulder 23 on pin 21 on to the turntable. The parts 26 and 31 and member 39 again occupyv the position indicated in Fig. 5 with regard to arm 18 and when the' latter is raised and swun back over the pile of re'cords in the magazine the member 39 is retained in this position, so that it cannot foul the upper record, the end 43 passing above it and the hooks' 46 outwardly of its edge.

be a 12" record,- then, as therod 38 is raised, bell crank lever 32 rocked and plates 43 of member 39 contacts with the upper surface of the record (Fig. 7) whereby movement of member 39 about its pivot 40 is limited.

In consequence the'hooks 46 are caused to occupy a position in the plane of the record and as movement of the parts 26, 31 and 39 towards the free end of the arm 18 continues, the record is caused to slide as before and is finally gripped between the recess 22 of pin 21 and the hooks 46, and'is ready for transfer to the playing position on the turntable in the manner described above.
