liill PatentedNov. 14, 1933 UNITED STATES PATENT OFFICE MAGAZINE TALKING MACHINE Application December 30, 1927, Serial No. 243,713, and in Great Britain January 19, 1927 18 Claims; (01. 274-10) This invention relates to improvements in and relating to talking machines and in particular to improved means whereby records may be removed in turn from a magazine, or a pile of records, and be conveyed to and deposited on the turntable of the machine for playing.

The invention relates in particular to machines of that type wherein the means for transferring records from the magazine to the turntable includes an arm swingable between a position over the magazine and a position over the turntable.

Among the objects of the invention are, to provide record transferring means which are quiet and reliable in operation, and enable the change of record to be effected in the least possible time, and to enable the record magazine to be reduced merely to a pile of records with means for cen tering the same. No expressly constructed container for the records is required. The improved record changing means are adapted to deal with both or 12" records, and records of these different diameters can be piled one on another in any order desired and be dealt with without special adjustment of the record changer.

The invention consists in a record transferring means of the kind referred to where-in the record engaging means on the swingable arm comprises a plurality of radially arranged arms, preferably resilient, the ends of which carry means such as hooks adapted to grip the edge of the uppermost record of the pile.

The hooks lie normally upon the circumference of a circle of slightly less diameter than the rec-v ord to be engaged and several sets of resilient arms may be provided, preferably super-imposed one on another so that records of another size may be transferred from the pile of records in the magazine to the turntable.

The hooks are disengaged from the edge of the record by means of a spider, the arms of which engage the under surface of the resilient arms to lift the latter when an upward movement relatively to the swinging arms is imparted to the spider.

The invention is illustrated by way of example in the accompanying drawings, as applied to an automatic magazine talking machine as described in my co-pending application Serial No; 243,712, filed December 30, 1927, Talking machines.

In the drawings:

Fig. 1 is a plan view of part of a talking machine to which the invention has been applied the record transferring means being shown in full lines in the position over the turntable and in dotted lines in the position over the magazine.

Fig. 2 is a perspective view of the transferring means in position where'the uppermost record in the magazine is engaged.

Fig. 3 is a perspective view similar to Fig. 2 the transferring device having made part of its movement towards the turntable.

Figs. 4 and 5 are front and end elevations looking from beneath and the left respectively in Fig. 1.

The machine comprises a base plate 1 supporting on its underside an electric motor 2 (Fig. 4) having the usual governor 3 and geared to drive a turntable spindle 4 journalled in the base plate 1. The usual turntable 5 is provided on spindle 4 and a sound arm and sound box (not shown) are mounted in the usual manner to swing horizontally about a vertical axis so that the stylus may traverse across the record. Supporting means for a pile of records comprise an arm 6 extending from one side of base plate 1 which arm carries a sleeve 7 having a plate 8 at its upper end upon which plate the records 10 rest. Within the sleeve 7 slides a spindle 9 which also passes through the central apertures in the records 10 piled upon the plate 8 (Figs. 2 and 3) to centralize the records in the pile.

The records 10 are transferred from the pile in the magazine one at a time to the turntable by transferring means which engages and moves the uppermost record of the pile.

The transferring means comprises an arm 12 having outwardly and downwardly projecting branches 30, '31 and mounted to rotate about a fixed axis situated at a point on the base plate 1 equidistant from the centralizing spindle 9 and turntable spindle 4. The axis is formed by a spindle 13 rotatably and vertically movable in bearings 14, 15 supportedby a casting 16 secured to base plate 1. The means for rotating the spindle 13 and thereby swinging the arm 12, is of the kind described in my co-pending application herein identified consisting of a curved lever 17 pivoted on the base plate 1 at 18cm end of the lever carrying a downwardly extending pin which engages in an aperture in a block 19 mounted to slide between the arms of a yoke 20 fixed to the spindle 13. The yoke'20 is formed integral witha ring 21 resting upon a shoulder'on the spindle 13 and the connection between said ring 21 and spindle 13 is effected by means of a spring and ball catch the ball 22 of which engages in a. recess in the ring 21,

the ball 22 being pressed into the recess by'a spring 23 carried on a ring 24 fixed to the spindle 13. By this means the arm 12 and spindle 13 is made capable of being moved independently of yoke 20 and lever 17, for example to permit records to be placed in 'or removed manually from the magazine.

The lever 17 is rocked about its pivot to swing the arm 12 between its extreme positions, by the engagement of its end 26 with a projection 27 on a horizontally moving plate 28.

This plate (Fig. 1) is caused to move once backwards and forwards when the turntable is empty and a record is required to be fed theretofrorn the magazine, this movement of plate 28 being effected by cam mechanism carried on a rotating cam shaft 29 adapted to be clutched at the appropriate time to the turntable spindle 4i or some other constantly rotating part of the machine as described fully in the specification of my co-pending application No. 243,712.

The means for engaging a record to lift it from l the magazine and to deposit it upon the turntable comprises three arms 32, radiating from a boss 33 fixedly mounted beneath the point of juncture of arm 12 and its branches 30 and 31 and these arms lie, one beneath the arm 12 and one beneath each of the branches 30 and 31. The arms 32 are in the form of light steel pressings connected to leaf springs 32' which in turn are connected to the boss 33 whereby the arms 32 are resiliently mounted. The arms 32 are inclined downwardly and are provided at their lower ends with hooks 34 formed by bending the ends of the arms and these hooks are adapted toengage under the edge of a record. The hooks 3a in the normal position, when no record is engaged, lie upon a circle slightly less in diameter I than the record to be engaged.

The centre of the boss 33 from which the arms 32 radiate lies, when the arm 12 'is in one extreme position, exactly over the record centering spindle 9 and in the other extreme position exactly over the turntable spindle 4. The boss 33 is provided with a downwardly extending sleeve 33 and-with a central aperture which registers with the passage through the sleeve 33 and with an aperture in the arm 12. .A spindle 35 is mounted so as to be capable of a limited vertical movement in the sleeve 33, the boss 33 and the aperture in arm 12, and the upper end of this spindle 35 is furnished with a head 36 which forms a stop to limit downward movement of the spindle 35. Near the lower end of the spindle 35 is rigidly fixed a three-armed spider 37 the arms 38 of which extend so that their ends lie beneath the arms 32. A clearance is left between spider 37 and the lower end of sleeve 33' and by raising the spindle 35 and the spider 37 carried thereon, the arms 32 may be lifted so that the. hooks 34 move radially outwards until they lie upon a circle slightly greater in diameter than the record which the hooks are adapted to engage. The lifting of the spider 37 may be effected manually by means of a lever 39 secured to the underside of the arm 12 through a leaf spring 40 and connected with a knob 41 by means of a short rod 42 extending through the arm 12. This lever 39 is provided at its free end with a pair of arms 39' which extend below the spider 3'7 and carry a pin 43 which engages the under surface of the spider to lift it when the knob 41 is raised. The

spider is also adapted to be lifted automatically in a manner yet to be described.

The. hooks 34 are engaged with the uppermost record in the pile by weight of the arm 12 during a downward movement of the latter, the hooks first engaging the surface of the uppermost record and then being spread outwards until the hooks 34 pass over the edge of the record.

Vertical movements are imparted to the spindie 13 and arm 12 both before and after the movement of the arm 12 from the position over the magazine to the position over the turntable and vice versa. The first vertical move ment'in feeding a record from the magazine is a lifting movement .to raise the uppermost record in the magazine to a plane where it can be swung to a position over the turntable without meeting any obstruction. The next vertical movement is a lowering movement over the turn table whereby the release of the record from the grip of the hooks 32 is efiected in a manner yet to be described, the next is a lifting movement preparatory to the return swing of arm 12 towards the magazine and the final vertical movement is the lowering movement to permit hooks 32 to engage the edge of the next record in the magazine. The means for imparting these ver tical movements to the transferring device comprise a rocking lever i i arranged beneath the base plate 1 and pivoted intermediate its length at 45, one end of which lever 44 engages beneath and is movably secured to the lower end of the spindle 13 while the other engages a box cam 46 fixedly mounted at the lower end of the cam shaft 29. The box cam 46 is provided with depressions 46' in appropriate positions which permit the lever 44 to rock at the proper time.

The record centering spindle '9 is also capable of up and down movement and its movements take place in synchronism with those of the arm 12 through a pivoted lever 4'? one end of which supports the spindle 9 by engagement with its 1 lower end while the other end of said lever d? rests beneath and rises and falls with that end arm 12 during the up and down movements of the latter. The pin 49 also serves to maintain the arm 12 raised when the latter is moved manually into an intermediate position such as when placing records in or removing records manually from the magazine, by resting with its lower end upon the flange 16"on casting 16. To allow" the necessary time for what may be, when the magazine is nearly empty, a lifting movement of considerable extent of arm 12 before swinging movement of said arm 12 towards the turntable commences, the projection 27 on plate'28 does not contact with the end 26 of pivoted lever '17 until cam shaft 29 has rotated -a part of a revolution and the plate 28 has travelled a given distance. The time occupied by arm 12 in moving vertically when over the turntable is of very short extent and it is desirable therefore that the return swing of the arm 12 shall commence almost simultaneously with the commencement of the return movement of plate 28. To this end a lever 51 is pivoted intermediate its length on the pivot 18 of lever 17 and one end of lever 51,

the other engages a surface 53 on plate 28. As the plate 28 moves to the right in Fig. 1 the lever 51 rotates in a clockwise direction with regard to lever 1'? until the latter is moved by projection 27, the end of lever 51 remaining in contact with surface 53. 'As soon as the direction of movement of plate 28 is reversed lever 51 is moved in a counter clockwise direction and owing table spindle 4. This engagement results in the lifting of spider'37 with regard to arm 12 whereby arms 32 are spread outwards and the record freed to fall gently upon the turntable.

In order that the apparatus may be capable of dealing with records of various sizes a plurality of sets of flexible arms are provided.

In the drawings two sets of flexible arms 32 are illustrated, one for 10" and the other for 12" records, one set being arranged above the other, and the hooks 34 of the upper set lie upon a circle of greater radius than that upon which lie those of the lower set. The upper arms 32 may carry spacing studs (not shown) to hold the upper and lower arms spaced from one another. It will readily be seen that when it is desired to disengage a record from the hooks 34 on the upper arms 32 the spider 3'? is raised as previously described to first lift the lower arms 32 which then engage the upper arms to raise these latter.

The operation is as follows:--

To charge the magazine the arm 12 is raised and swung into an intermediate position where the pin 49 rests upon the flange 16 on the casting 16. In this position the levers 44 and 4'? are rocked, owing to the connection of lever 44 with the lower end of spindle 13, so that record centering spindle 9 is raised. The placing of records in the magazine is thereby facilitated and the records are correctly centralized.

The arm 12 is then returned by hand to the position over the magazine and allowed to drop. Levers 44 and 4'? are permitted to return to their former position and spindle 9 is lowered so that no obstruction is oflered to the downward movement of the record engaging means, the lower end of spindle 35 entering the central apertures in the records. The lower ends of the arms 32 engage the surface of the topmost record in the magazine and as the lowering movement of the arm 12 continues the arms 32 spread until hooks 34 pass over the edge of the record and grip the edge.

If the uppermost record is a 10" record the hooks 34 of the lower set of arms 32 engage the edge of the record, the hooks on the upper set spreading outwards beyond the edge of the record as shown in Fig. 3. If the uppermost record is a 12" its edge is enga'gedby the hooks 34 on the upper set of arms 32 the hooks on the lower set remaining in contact withthe surface of the record but spreading sufficiently to permit proper engagement of the upper set of hooks.

The arm 12 remains in this position until the cam shaft 29 commences to rotate whereupon the lever 44 is rocked by box cam 46 and spinesamo dle 13 and arm 12 are raised together with the record engaged by hooks 34.

The arm 12 is next swung to a position over the turntable 5 by the engagement of projection 27 on plate 28 with the end of pivoted lever 17. When the arm 12 reaches the position shown in full lines in Fig. 1 the lever 44 is again permitted to rock by the box cam 46 and the arm 12 is lowered until the lower end of spindle 35 contacts with the upper end of the turntable spindle 4. The spider 37 is thereby raised with regard to arm 12 and its arms 38 engage the undersides of resilient arms 32 to push the hooks 34 outwards and the record is released to fall upon the turntable. As previously stated the vertical movement of arm 12 in this case is of comparatively small extent. The arm 12 is next raised by cam 46 through lever 44 and is then swung back to the position over the magazine by the return movement of plate 28 towards the left in Fig. 1. When over the magazine the arm 12 is again permitted to drop and the hooks 34 pass over and engage the edge of the now uppermost record in the magazine in the manner previously described.

The means employed for removing a record from the turntable when played may be of any suitable kind such as that described in my copending application No. 243,712 previously referred to.
