WILLIAM C. ROE, OF PITTSBURGH, PENNSYLVANIA.

PHONOGRAPHIG ATTACHMENT. 7

Application filed May 5, 1919. Serial No. 294,859;

Be it known that I, EWILLIAM C. Ron, a

citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Phonographlc Attachments, of which improvement the followingis a specification.

My invention relates to improvement in phonographic'attachments for starting and sto ping the mechanism used to rotate the table carrying the record. The object of this invention is to produce a mechanism of this kind having the following characteristics, viz

1. The capacity of starting the mechanism by the movementof' the tone arm.

2. Of automatically stopping the machine at the end or completion of any record, regardless of its length and without special or previous adjustment or arrangement, and

Finally, the production of a stop and start mechanism for phonographs having a minimum ofparts with a maximum of strength therein, and which can be made at small cost.

I accomplish these objects by means of the device hereinafter more specifically de-' scribed, reference being had to the accompanying drawings forming part hereof, in which I Figure 1 is a plan view of the top of the machine,

eferring to the said drawings, and par ticularly to Figures 1-7 inclusive; 1 isthe box or receptacle within which the actuating mechanism of the usual construction is secured. 2 is the table or platform which is centrally mounted upon. the spindle 3i which is adapted to be connected with the actuating mechanism (not shown) in the usual manner. The said table is adapted to carry the record 4. 5 is the tone arm of the usual construction and is supported on one side of the box in the usual manner. 6' is a worm gear on one end of the shaft .7 which meshes. with the toothed pinion 8 on the s indle 3. The opposite end of said shaft 2 is also provided with a Worm gear 9 which meshes with the pinion 10, which is integral with or secured to the thimble 11} which is mounted on the spindle 12. 13 is a toothed pinion-loosely mounted on the upper end of the thimble 11, said toothed pinion being free to move in one direction onl when engaged by the serrated or toothe edge of the arm 14, which is connected to and carried by the tone arm 5. 15 is a friction washer mounted on said thimble 11 between the shoulder thereon and the lower side of the loose pinion 13, the function of said washer being to produce sufiicient friction to hold the pinion against movement momentarily, whereby the continued rotation of the thimble causes the ball 16 to be wedged against the thimble, locking the pinion '13 to the thimble and causingt thesshiftable member 17 to move or swerve toward the right to the extent of the play between the teeth of the toothed arm"14, the teeth of the pinion, thus throwing the hooked end of the arm 18, which is integral with the shiftable member 17 out of engagement in the notch b in the edge of member 19. Under such conditions the retraction of the spring 20 one end of which is connected gagement with the'inner surface of the periphery of the table 2, as shown in dotted hooked end of arm 18 in contact with the edge of both members 19 and 23. .It will be seen that the member 17 is pivoted on the shaft 3, and that the arm 18 is intregal' to the lines Figure 1 stopping the same. The said members 19 and 21, with the member 23 and the auxiliary parts thereof, constitutes the stop'and start mechanism. The said member 21 comprises a substantially circular plate-mounted on the pin 24, on which is also mounted the member 19, the said member 23 having a handle or projecting arm 25, which constitutes the usual stop means, as by throwing the said handle, as shown in dotted lines. Figure 1 carries the highest curved portion e,-of said member 23 into engagement with the hooked end of arm 18, throwing the samel out of en gagement with the notch b, and permitting the retraction of the spring 20, as heretofore described, to carry the brake arm 22, into contact with the inner surface of the rim of the table, stopping the same. The compression spring 26 one end of which is secured to the upwardly projecting prong g, on the member 23 and the opposite end rong d on member 21, serves to throwt e handle 25 into, and out of operative position.- Each of said members 19 and 23 are provided with, respectively, re cesses h, k in which the prong d on member 21 projects, the length of said recesses limiting the rotary movement of both said members. The spring 27 serves to hold the with the member 17,. though it may be secured thereto in any suitable manner. It

will thus be seen that the rotation of the member 17 will cause a corresponding "rotation of the arm 18, the outward extremity of which arm engages the member 19 in the slot 6. I

With this arrangement of my invention, it' will be seen that when the phonograph needle is carried into operative engagement with the grooves of the record, the teeth of thev arm 14 will pass into engagement with the teeth on the pinion 13. The pinion 13 is arranged to rotate relative v to the pinion 10, to permit such engagement between the said teeth on the arm 14 and- The result is that the pinion 13 is locked into engagement with the shaft 12 through the action of the ball.

The whole member 17 is then rotated on the shaft 3, and the-outer extremity of the arm 18 is lifted out of the slot 6 in the to the position indicated by the dotted linesof Fig. 1, wherein the arm 14-engages the trigger projecting inits path which is shown in ig.-1 and Fig. 9, extending upwardly from the rotatable member 19; the motion of the member 14 further to the right will rotate the member 19- about the point 24 until the hooked endv of the lever 18 will fall into the notch B on the member 19, the arm 18 being drawn into the said notch by the spring 27.

The rotation of the member 19 will cause the brake arm 22 to move clock-wise about the center 24, and to become disengaged from the peripheral flange of the table 2, where, consequent to the action of the automatic' stop mechanism hereinbefore de scribed, said brake arm maintained the brake contact carried at its end in frictional engagement with the platform or-turn-table 2- to prevent its rotation. The turn-table will now rotate clock-wise, and the operator will place the needle of the phonograph reproducer in the record groove at the start thereof, whenceforth, the tone arm 5 will be rotated clockwise to the end of the rec-' 0rd, when it-will again come to rest and Whenever automatic starting of the turntable rotation is not desired, the turn-table may be started or stopped by manipulating the handle 25in the one or the other direction to place the brake 22 into or out of engagement with the turn-table flange.

in Figures 14 and 15 I show a modified form of my invention and which is preferred, on account of its greater simplicity, to that illustrated in Figures 1 to 13 inelusive. In said Figures 14 and 15, .28 is a spindle which is adapted to be connected with the drivingmechanism (not shown) in the usual manner. The said spindle is provided with a worm 29, which meshes with Ill] a gear wheel 30 on one end'of the shaft 31,

the opposite end of said shaft having a worm 32 which meshes with and transmits power to the gear wheel 33 which is mounted on the lowerend of the spindle 34, the ,lower end of which is supported in a bearing formed in the shiftable link 35. .The opposite end of said link is pivotally connected to and mounted on, one end of the link 36, the opposite end of said link being mounted on the pin 37 and terminates in a handle 38. A thimble 3-9 is mounted on said spindle 34 and supports a gear wheel 40 loosely mounted on the upper end of said spindle 34. The said gear Wheel 40 meshes with the teeth or serrations on the end of the arm 41 which is connected to the tone arm of the machine in a similar manner to arm 14. 42 is an arm one endof which is mounted on the thimble 43 which is mounted on the pin connecting links 35 and 36. The opposite end of said arm terminates in a hooked portion adapted to engage in a notch n on the member 44, which member is mounted on the pin 45 and is provided with a handle 46 and a hooked prong 47 adapted to engage over the arm 42. The projecting finger 48 and the brake arm 49 are also provided. 1

In Figures 16 and 17 I show another modification of my invention. In said figure 50 is the box or receptacle; 51 and 52 are respectively, the table and record thereon; 53 is the spindle adapted to be connected to the operative mechanism 'in the usual manner. The said spindle has mounted thereon a gear wheel 54 which meshes with and transmits motion to the gear wheel 55 on one end of the shaft 56, the opposite end of said shaft having mounted thereon the worm 57 which meshes with the gear wheel 58 mounted on a pin 59 secured in the plate 60. 61 is a similar gear mounted upon the pin 59 above the gear wheel 58. The said gear 61 meshes with the gear wheel 62 on the spindle 63 which is mounted on one end of the shiftable link 64. The opposite end of said link is connected to the vertically disposed pin 65 to the upper end of which one end of the arm 66 is secured. The upper end of said spindle 63 has mounted thereon the loose gear 67 which meshes with'the .teeth or serrations on the end of the arm 68, which is attached to the tone arm 69 in a manner similar to arm 14. The said arm 66 projects towards the outer periphery of the table and is provided with a recess an, adapted to engage the brake arm 69 of the stop and start mechanism. The

said stop and start mechanism comprises a plate 70 carrying said brake arm andhaving an upwardly projecting prong 71to which one endof a sprlng 72 issecured, the opposite end of which spring 72 is connected to a pin in the frame of the machine. The saidplate is provided with the usual start lever 73 and the stop lever 74.
