1 The present inventionreiates .to an improved phonograph of the type comprising, in combination, a reproducing device provided with a cirby which any selected record may be transferred from said magazine to the said circular plate, and inversely.
The said apparatus is chiefly characterized in 10 that the'device employedto' transfer the record from the magazine to the circular plate and in versely, consists of a fork or analogous device provided with membersfor seizing the record,
, the movements of said fork or analogous device 16 being such that said members for seizing the record are movable upon a given constant path between two stationary points, one of them being located above the said circular plate and the other being situated at'a point in space before which the selected record is brought by a suitable displacement of said magazine.
According to another feature of the invention, the fork or other seizing device is pivotally mounted on a frame which is adapted to turn 26 about a stationary axle pin and is connected, by a crank and a link, to a suitable fixed point, whilst a cam secured to the said frame actuates the said fork or like device.
' According to a further characteristic of the '80 invention, the selecting device which controls {can be placed in or out ,of gear engagement by means of the selecting device. V
., Further characteristics of the invention will be set forth in the following description.
46 In the accompanying drawings, which are given solely by way of example: I Fig. 1 is a u tic elevational view of an apparatus constructed inconformity to the invention, said apparatus being represented in moment when r the record leaves the magazine.
Fig. 2is an-analogous view, showing the reconi at anintermediate point on its path, and
vl 'ig. 3 a similar viewinthe position in which 86 therecordisadjacent the circular plate.

-' 5 is a plan view of the device controlling cular plate for rotating the record, a magazine 6 containing the record, and an automatic device" the record carrying fork.
Fig. 6 is a partial elevational view showing the device adapted for releasing the record which is placed upon the circular plate.
Fig. 7 shows a modified form of the magazine. Fig. 8 shows a general view of a phonograph with the details ofthe electric circuit. Fig.9 is a partial section on line 9-9 of Fig. 1.
In the form of construction represented in Figures 1 to 6, the apparatus comprises a stationary frame consisting of uprights 1 "and horizontal cross-pieces 2. Upon the table formed by the said cross-pieces is mounted a reproducing device 3 of the acoustic or the electric type, whose stylus 4 movesover a record carried by a rotatmechanlsm.
Beneath the cross-pieces 2 is mounted a megazine 6 containing the records. In the present construction, the said magazine consists of a semicylindrical support in which are formed equidistant'grooves '7, each'of them being adapted to 30 receive a record 8. All of the records have the vertical and parallel position, and are side by side. The support 6 is movable in the direction of the arrow 1 or in the contrary direction, and is carried and guided by rods 9 which 86 are secured to the frame.
The magazine 6 can be displaced in any suitable manner, and for instance by means of a selecting device 10, of a known type, and provided with a sprocket wheel 11 adapted to drive a shaft 14 by means of a chain 12 and a sprocket-wheel 13. Said shaft carries a pinion 15 in gear engagement with a rack lfisecured to the support 6.
Upon the shaft 17 of the driving wheel ll'is moimted a cam 18. A lever 20 pivotally mounted 06 uponapin21bearsuponsaidcam20 throughthe' intermediary of an arm 19. The outer end of the lever 20 carries-a portion of a crown-wheel- 22, whose position in height will thus depend upon the position of the cam -18 at its point of contact with the arm 19. The said cam 18 and the sprocket-wheel 15"actuating the rack 16 are so constructed that one unit rotation of the wheel 11 of the selecting device 10 assures alternately on the one hand a unit displacement of the rack 16 and hence of the magazine 6, and on the other hand the descent of the toothed member 22.
The apparatus further comprises a mechanism for the transfer of each record 8 from the magazine 6 to the phonograph plate 5. and inversely. A frame 24 is pivotally mounted upon a horizontal axle pin 23 secured to the uprights 1, said frame carrying two parallel and lateralplates 25. Upon the said frame is mounted an electric motor 26 (Fig. adapted to drive-by means of the worm gearing 27--28a shaft 29 journalled in lugs 30 and 31 pertaining to the frame 24. The shaft 29 drives-by worm gearing 32-33 or the like-a shaft 34 journalled for example in one of the plates 25; said shaft carries a disc 35 on which is pivotally mounted, in the eccentric position at 36, a link 3'! which is pivoted at the other'end to a stationary shaft 38 HOT secured to the uprights 1. Thus when the motor is in operation, and under the action of the crank-disc and the link 37, the frame 24 will oscillate between two extreme positions, as shown in Figures 1 and 4 and Figure 2.
Upon the shaft 34 is keyed a pinion 39 (Figures 1 and 5) en aging a gear-wheel 40 which is keyed to a'shaft 41 mountedin the plates 25 and carrying a cam 42 which is in contact with a roller 43 situated at the rear end of a fork 44.
The said fork 44 is pivotally mounted on a spindle 45 secured to said plates 25, and the distance between the two parallel branches of the fork somewhat exceeds the diameter of the records 8. At the end of each branch of the fork is mounted a device for seizing one of the records 8,
Esaid device may consist (Fig. 6) of a forked bracket 46 mounted at the end of a shaft 47 which is slidable in the end of the arm 44. A spring 48 urges the forked bracket in the direction of the arrow f, for the engagement of said bracket with the record 8. The releasing of the bracket from the record 8 may be assured by any suitable means, for instance by mechanical or electric means. In the device shown in Fig. 6, the shaft 4'1 ends in knob 49 co-operating with .1 a stationary ramp 50 (Figs. 1 and 6); said ramp tion (the arm 19 being between two projections of the cam 18, as shown, in Figs. 1 and 2). Due
to this gear engagement. the pinion 51 and the shaft 4'7 will make half-a-revolution.
The mechanism is completed by devices 52 for guiding the record 8 when it begins to rise.
and by stops 53 with which the record makes contact somewhat before the end of its movement towards the plate 5.
The operation is as follows. Under the combined sction'of the oscillations of the frame 24' and of the cam 42. the fork 44 oscillates between two extreme positions (Figs. 1 and 4).
for which the shafts '47 of shid fork will be.
- is regulated by the selecting device 10. It will be supposed that the record to be employed is the first record on the left (Fig. 1). For this position of the magazine 8, the curved toothed member 22 is in the raised position. The first record 811 is thus raised out of the magazine. The form of cam 42 and the movement of frame 24 are such that the first part ab of the path of shafts 47 is vertical, and thus record 8a rises vertically, it being guided by the device 52. This vertical rise is necessary, in order that the record may be released from the magazine, this being particularly important in the case of the intermediate records.
The path then becomes curved from b to c, due to the form of cam 42 and the record 8a, which is now released from the guide 52, assumesan inclined position (Fig. 3). The record finally arrives at 8d, upon the plate 5, as shown in Fig. 4.- At the end of the stroke of the fork 44, the knobs 49 situated at the ends of the shafts 47 make contact with the stops 50 and recede, thus releasing the record.
The operation for the return of the record to the magazine 6 is effected in an analogous manner.
As the records carry the record on both sides,
it is necessary that they shall be laid upon thev instance, this record -8a is laid upon the plate 5 with its left-hand side downwards (Fig. 1). If the selecting device 10 is moved by one unit, the cam 18 will now offer arecessed part to the arm 19 (as herein represented), and the pinion 15 will be out of engagement with the rack 16 of the magazine 6 (for instance by separating the teeth of pinion 15 by a space twice as large as that of the teeth of rack 16), and hence the said magazine will remain in the fixed position, while the toothed member 22 descends. In this-position, the same record 811,-
which is the first to the left, for instance, will be again seized, but when in coincidence with the toothed member 22, the pinion 51 is nowrotated and makes half-a-revolution, thus turning the record 8a to a like degree, and hence the record .will be laid upon the plate 5 with its right-hand side down (Fig. 1). On the return movement, the pinion 51 will turn the recordin the other direction, and thus the record will be placed in the magazine 8 in the same position as at the start.
when the selecting device 10 is operated by another unit, this'will remove the toothed member lrrowflmrinthecontrsrydirection), on,byenslternstemotion,intheesseofan operation by separate units. Obviously. the

The following descriptionwillshow together with Fig. enampleofsuchletustingmesns. Itisilrst en ma shaft 41 is mountedsdisciiS providedwithsnotehfl. A lever 6'! is benotedthstthemeshingsesrwheelsmsnd- W mounted at 58 and is pros-1 with a point 59 and a finger 60. Said point is adapted to engage said notch 56, whereas the tinger 60 is adapted to actuate a piece 61 against a reaction spring (not shown). The piece 61 in turn actuates a contact 62. Electric current is supplied by the wire 63 up to a contact 64 on the selecting device 10. This-contact may be operated by a coin and is of any known type. From contact 63 the wire leads to the motor 65 adapted to drive the turntable 5. The wire enters the motorat 66 and leaves it at 6'7, it then passes over a contact 68 on the motor 26 foroperating the oscillating frame and returns to the source.
Contact 66 is connected by a wire 69 on one hand with contact 62 and, on the'other hand, with a contact 70, the latter being operated by the sound arm 3. Finally, the second point of contact '70 is connected by a wire 71 with contact 62 and contact 68.
The operation is as follows: A coin being introduced into a suitable chute on the selector 10, contact 64 is'closed and current is supplied to motor 65 which begins to rotate. Contact 62 being normally closed, the motor 26 also rotates and the forked member 44 raises the record. The rotation of motor 26 continues until point 59 engages notch 56, lever 5'7 being then rotated and opening, by means of finger 60 and piece 61, contact 62. The motor 26 stops and at this moment the record is already situated upon turntable 5.
The member 44 at the end of its motion and while lowering the record has actuated by means of finger 72 a piece 73 which in turn provokes the rotation and lowering upon the record of arm 3 due to suitable ramps (not shown). When the record has been played, the arm 3 occupies a position adjacent contact 70 and closes this latter. Thus current is again supplied to motor 26 which latter begins to rotate, disengages point 59 thus closing contact 62. Arm 3 is raised and brought aside and record 8a brought back into the magazine. When at the end of its track arm 44 actuates, any spring operated lever and opens contact 64. In this way roller 43 is displaced upon half the periphery of cam 42 when the record is raised out of the magazine and upon the second portion of this cam when bringing the record back into 1 in any suitable manner.
The said invention is not limited to the forms of construction herein described and represented, which are given solely by way of example, and for instance, the device 46 for seizing the records may have any suitable form, such as a fork, a clamp, or the like.
Having now described my invention, what I claim as new and desire to secure by Letters Patent is:
1. In a record changing mechanism according to claim 3, the further feature residing in that said clamping means are adapted to yieldingly engage the selected record, and fixed stops are adapted to cooperate with said seizing means for releasing said record when in position upon said rotary plate and in the magazine.
2. In a magazine phonograph, a record changing mechanism comprising means for conveying a selected record from the magazine onto the rotary record supporting plate, selecting means controlling the displacements of the magazine, a
relatively fixed toothed member operatively connected with said selecting device, a shaft provided on the conveying means and supporting the record carrying members, and a pinion mounted on said shaft and adapted to temporarily cooperate at will with said toothed member on its path from the magazine toward said rotary plate and inversely for overturning said record.
3. A record changing mechanism comprising clamping means for positively seizing a record in the magazine, conveying means pivotally supporting said clamping means and adapted to positively raise a selected record out of said magazine to convey and to lay it on the rotary plate of the phonograph and to bring it back into the maga- 'zine after it has been played and to follow thereby 'a continuous path, a cam actuating said conveying means, a motor controlling said cam, an oscillating frame pivotally supporting said cam and said conveying means, and means for oscillating said frame.
4. In a record changing mechanism accordingto claim 3, the further feature residing in that record-guides are provided over the record magazine for avoiding the rotation of said clamping means and thus for maintaining the raised record in a vertical plane until the record has completely left the magazine.
5. A record changing mechanism according to claim 3, wherein said frame oscillating means consist of a crank and link device operatively connecting said motor and said frame.
