6 Claims.

This invention relates generally to electrically operated sound reproducing machines and is more particularly directed to mechanism for supporting a plurality of records stacked above the turntable of a reproducin machine and operable in timed relation. to other and cooperating mechanisms of the machine to successively release the records .ior disposition upon the turntable for reproduction.

Tlie primary object of this invention is to provide an improved mechanism for machines for reproducing recordings on discrecords, for e'fiecting the delivery of such records of the same 7 or different diameters, one at a time, for dis-' position upon the turntable or.other support in reproducing position.

More specifically, thisiinvention comprehends an automatically operating mechanism for electrically driven phonographs, for successively delivering a series of records stored in a stack formation above the turntable a phonograph, for disposition thereon in'reproducing position, by

releasing the records one at a time from the bot=- tom of the stack and concurrently lowering the remaining stacked records by one position to present another recordin releasable position.

Other objects and advantages flowing from the practicing of my invention will become evident as the description proceeds.

For the purposes of this disclosure, I have elected to show and describe my invention as it may be incorporated in an electrically driven phonograph. such as shown in my co-pending application, Serial No. 392,200, filed May 7, 1941, which matured as Letters Patent No. 2,297,014, dated September 29, 1942, for Magazine phonographs, of which this application is a division, to cooperate in appropriately timed relation with other mechanisms thereof, in the functioning of r the phonograph. However, this is merelyv illustrative,. since, as will become manifest, my invention may be employed to equal advantage in other types of sound reproducing machines, electrically driven or otherwise, where automatic delivery of disc records to reproducing position is essential or desirable.

In the accompanying drawings, I have illustrated a preferred and practical embodiment of my invention; as used in a phonograph of the specific type disclosed in my aforesaid copendlng application, in which Figure l is a View in perspective of ,an electrically driven phonograph embodying my invention.

Figure 2 is a side elevational view of the phonup arm mounted on the motor board 32 and c Figure 4 is a perspective view of a detail of Figure 3.

Figure 5 is a sectional view along the line 5--5 of Figure 3.

Figure 6 is a longitudinal section along the line iiiiv of Figure 5.

Figure 7 is a view in elevation, partly in section, showing the record magazine in readiness to discharge the lowermost record, and

Figure-8 is a view similar to Figure 7 showing the lowermost record discharged from the magazine for disposition upon the turntable.

Referring now to the drawings in detail, in

which like characters of reference are employed to designate similar parts in the several views, the phonograph, as shown, includes a tone or piclra turntable 33 embodying a record centering pin 34. A pair of diametrically oppositely disposed elevators l1 and 58 cooperate in the disposition of a record releasedirom the magazine, generally indicated by the reference numeral 35, upon the turntable, the records being retained in concentric relation in the magazine by the pin-ii vertically movable in the sleeve 38 carried by the arm 40. A knob 4| is provided for raising the pin 31 within its sleeve, to admit of stacking the rec-: ords within the magazine 35. A record support ing arm 50 is rotatableinto position beneath the,

record in the lowermost magazine position to cooperate therewith in supporting the stacked records, except during aperiod of coordination of the phonograph mechanisms'whenone of the elevators coacts with the magazine as a record support in engagement with a record is about to be released. as will be hereinafter explained in reater detail, another swingably mounted am).

42, being provided for reversing the records to I admit of the reproduction of both recordings thereon, and conveying them to the storage re I ceptacle H3 for disposition therein. For detecting the diameter of a magazine released record, a feeler arm 5| carrying a roller 52 is mounted adjacent the turntable 33 while provision is made for automatically 1 stopping the phonograph mechanisms by the actuation of a master switch, by means setlin operationby the clockwise rotation of-the arm 53 which abuts upon the edge includes a system of cams shown in Figure 2, the

shaft 60 carrying the gear 83 being driven through suitable reduction gearing from a motor.

by meansof the pinion 62 in mesh with said gear 3, the other end of shaft 60 is provided with a ear'fl in mesh with pinion 85 to drive the stub shaft 68. The cams on the stub shaft operate pick-up arm and the feeler arm UI, for ex ample, while the cams on the sleeve 68, which is adapted to be coupled to the shaft Oil by the clutch 265, function in the operation of'the record changing mechanism, one of these latter cams, indicated at 15, actuating the mechanism for releasing a record from the magazine, as

hereinafter described.

The magazine includes a series of vanes 36 rotatably mounted above the turntable 33, the

the driving shaft I by the clutch III, as aforesaid. As will be noted, the rotatable'sleeve 14a embraces a column," on which the vanes are mounted for individual rotation independently of said column, the vanes as herein shown being assembled upon said column between the head ,lla and the collar llb, both of which are pinned to saidcolumn, withsuitable spacers 10c interposed between adjacent vanes, to maintain them in vertically spaced relation. Obviously, in lieu of these. spacers, each vane may embody an integral hub to attain the requisite spacing of the record-engaging portions thereof. The head 18a is chambered for the reception of a spring lid, for maintaining the opposed surfaces of the vanes and cooperating spacers in close frictional association and to provide for the rotation of the series of vanes and said column as a unit, for returning the vanes to record-engaging position, when the column is vertically actuated in its bearings lie, as hereinafter described.

-The downward movement of the series of vanes, is produced in a like directional moverecord being released therefrom by the rotation of the lowermost vane clear of the edge of the record positionedthereon, the details of the vane actuating and control mechanism being clearly shown in Figures 3 to 6, in conjunction with Figure 1. The-means for actuating and controlling the vanes is an improvement on the construction shown in U. 8. Patent No. 2,188,769 to Downs.

The records R, which may be of mixed diameter, such as 10" and 12" records, are supported in vertically spaced relation by a series of vanes ll forming the magazine adjacent one side of the motor-board 32, each vane being adapted to engage beneath the under marginal surface of a record to support the records in conjunction with the arm III in stacked position above the turntable 33. The support arm is operated by one of the cams mounted on thecam sleeve. is to.

cooperate with the actuation of the vanes in a manner to release the records one at a time onto the aforesaid elevators l1 and II which are then actuated to lower the record onto the turntable.

rotation of the lowermost vane frombeneath the record to permit the latter to drop onto the ele-- vator 48 which has been raised to receive it, the

arm 50 again swinging beneath the record in the lowermost magazine position, to support the ment'of the column I6, step by step, within its bearing We, the column being supported in its highest position, by the upper end of the segmental extension ll of the sleeve 14a in engagement with the lowermost vane of the series. When the lowermo t vane is rotated out of recordengaging position, hereinafter. described, to a storage position, column 18 moves downwardly until the next vane of the series is engaged with said extension to support the vanes in recordengaging position, and so on throughout the operation of the mechanism Each vane 38 is provided with a lateral projection 11 at its column engaging end, which is formed for abutting engagement with the face of the ledge 18 projecting laterally from the upper end of said segmental extension N, which, in effect, is a continuation of the sloping cam surface 80, which rises from a point just above said ledge to its peak at the opposite side of said extension. Thus, when sleeve Ila and its segmental extension 14 are rotated as a unit, in a clockwise direction, the vertical surface of the ledge pressing against the engaged projection 11 of the lowermost vane 38 urges the vane in a like directional movement out of record-engaging position to a storage position at an angle of 90. degrees thereto. I

In this clockwise rotative movement of the segmental extension 14, the cam surface 80 thereof rides beneath the projection 11 of'the next lowest vane to-support the remaining mines of the series, the peak of the cam surface taking the load, when the ledge 18 reaches its ultimate position in the propulsion of the vane engaged thereby to its storage position. As the rotation of the segmental extension is reversed. in' resp nse to the spring actuation of the lever IS, the recession of the cam surface 80 beneath the vane projection stack, as the downward movement of the elevator 41 is initiated to coact with the like directional movement of the elevator 48 in conveying therecordto the turntable. As: each record is released from the magazine. the vanes and the records engaged therewith are lowered a sufiicient distance to bring the next vane, which becomes the lowest'of the series, into position to be swung laterally for release of the record engaged therewith. See Figures l and 8.

" The lateral movement of each vane in turn is effected in response to the rotation ofthesleeve Ila and its segmental extension 14. by the cam II mounted on the sleeve II which is coupled to abutting thereon produces a controlled downward movement of the record-supporting vanes with the column 16, until this movement is arrested as the projection 11 of the vane in engagement withthe cam-surface drops. onto the led e ll, as the segmental extension reaches its suitable buffer (not shown) of resilient materiah To prevent rotative movement of the vanes slots 82 in the pillar 8|.

2,352,562 above that in engagement with the ledge 78 of the segmental extension of the sleeve Ila, from record-engaging position, I provide a pillar 8| vmally, the projections H of thezvanes above the lowermost one in engagement with said ledge abut upon the portions of the flange between said open end slots to retain the vanes in record-engaging position.

' The sleeve "a, as stated is automatically rotated by the cam 15, the pinion 83 rigid with the lower end of said sleeve meshing with the rack 84 which is connected to one end of the lever 85 for reeiprocation'thereby. The lever 85 is pivotally mounted intermediate its ends, as at 86, the lower end thereof being connected to a fixed surface by the biasing spring 81. An arm 85a integral with said lever 85 carries a cam follower 88 continuously disposed in the pathof rotation of the nose 15a of said cam 15 for engagement thereby to rock said lever 85 counterclockwise, to

- actuate the rack 84 to the left (Fig. 3), causing leeve Ma and its segmental extension 14 to rotate in a clockwise direction to effect the rotation of the lowermost vane through an arc of 90 from its record-engaging position to its storage position, as set forth. The rack 84 is oppositely actuated (to the right) as the lever 85 is rotated clockwise under the influence. of said spring 81, inducing counterclockwise movement of the sleeves Ma and its segmental extension I4 for the disposition of the projection 11 of th! cam surfac supported vane upon the ledge 18 of said tofore explained.

When all of the records have been reproduced. the vanes which have been eachzrotated to storage extension, as hereposition in the successive release of the records from the magazine, may be returned to recordengaging position by raising the column 16 by means of the knob 9il to a position where their respective projections ll are aligned with the The manual rotation of the column counterclockwise permits the vane projections to pass through said slots to abut upon the flange surfaces therebetween as the column is released to move downwardly to its initial position, with the lowermost vane projection bearing upon the ledge 18, as described. This in sures correct alignment of all of the vanes for loading. I

The lower end of the column 16 carries a ratchet wheel 9| rigid therewith which is engaged by a pawl 92 urged into engagement with said wheel by the spring 93, the pawl being pivoted to plate 94. This plate 94 is bifurcated, as at 95, to embrace the rod 96 for sliding movement thereon when column 16 is vertically actuated, the pawl 92 in engagement with the ratchet wheel 9! preventing rotation of the column 16 by the clockwise manipulation of plate 94 is-restrained from ment with said rod 96.
