Specification of Letters Patent.

Patented Aug. 15, 1905.

Application filed May 28, 1904. Serial No. 210,153.

.To all whmn it may concern.-

Be it known that I, ENOCH J. Ruoron, a citizen of the United States, and a resident of Parkers'burg, in the county of Wood and State of l/VestVirginia, have invented a certain new and useful Improvement in Phonographs, of which the following is a specification.

One object of the present invention is to attach a phonograph to and operate the same by the driving-belt of the ordinary sewing-machine or the like.

Another object is to simplify and improve the construction and operation and to reduce the cost of manufacture of the phonograph.

Other objects Will appear hereinafter.

One form of the invention is illustrated in the accompanying drawings, forming part hereof, in which- Figure 1 is an end ele vation of a sewing-machine and phonograph attached thereto. Fig. '2 is a plan view, partly in section, of the phonograph. Fig. 3 is an end elevation of the same, partly broken away to show more clearly certainparts; and Fig. 4 is a front elevation of the same, also partly broken away.

Referring to the drawings, the referencenumeral 1 marks a sewing-machine end frame, and 2 the table. 3 marks the usual treadle; 4, the usual belt driven from said treadle, and 5 the usual fly-wheel-driven by the belt. Inasmuch as the sewing-machine is a well-known article, its details need not be more particularly described; but it may be remarked that the sewing mechanism is and preferably should be disconnectible in order that the noise of running the same may be avoided when the phonograph is in use.

The reference 6 denotes a base-board which is adapted to be placed on the table 2, and 7 marks a spring-clamp for holding the board and phonograph in position on the table.

The reference 8 denotes a sheet-metal framework preferably stamped out of one piece and bent into shape and locked together by lugs 9 to form a rigid construction.

1O denotes a rod or shaft which, by preference, is fixed in and projects at one end beyond the box-like part of the framework 8, and 11 designates a tie-rod for holding the boxlike part rigidly together in addition to the lugs 9, or the shaft 11 may rotate and form an axis for members of the train of gears hereinafter mentioned.

The rod or shaft forms a support for the record holder and its driving gear. The

holder shown in the drawings consists of leafsprmgs 12, which have their ends made fast in the gear 13 and have their outer surfaces curved to fit the inside of the hollow record.

and which have their middle portions formed into loops 14, united by straight parts 15. The parts 15 are connected by a screw or pin 16 with the end of the shaft 10 and rotate on said screw or pin when the said rod or shaft 10 is fixed, and the like is true of the gear 13 in such case. The looped ends of the holdersprings are, by preference. of greater diameter than the holder is where the springs are bent to connect them to the gear 13that .is, the holder is of greater diameter at the end thereof farthest from the gear 13. The springs compress as the record 17 is slid on. The described holder gives a firm grip on the record at all times and prevents the same from working loose, while permitting of its ready removal at any time.

The gear 13 and record-holder are driven from the belt 4 by means of a belt-pulley 18, the shaft 19, to which the pulley is fast, and the pinion 20, which is fast on the shaft 19 and which meshes with the gear 13. The speed of the gear is controlled and varied by the following devices: A disk 21, loose on the shaft 19, is connected by leaf-springs 22 to a collar 23, fast on the shaft 19, and weights 24 are fastened to the springs 22, so as to bend said springs and move the disk 21 along the shaft 19 whenever the speed of the shaft 19 rises beyond a given rate, and a brake device is provided against which the disk 21 is drawn by the weights, said brake being marked 25. The brake 25 is carried by an arm 26, which is held between the shaft 10 and theframe 8, and the position of the brake 25 may be varied by means of a screw 27, which has a groove 28 therein which engages with the arm 26. By turning the screw 27 the position of the arm 26 may be varied, thus varying the point at which the weights bring disk 21 into contact with the brake 25.

The speaker or reproducer 29 is mounted on a tubular elbow 30, which is pivotally connected by a hollow ball-and-socket joint 31 to a carrier 32. A pin-and-slot connection 33, between the members of the ball-and-socket joint, allows the speaker to rise and fall in order to put on and take off records. The carrier 32 slides on a guide 34, which is sleeved on the feed-screw 35 and which is held from rotating by a rib 36 on the base of the frame 8 and a cooperating lug 37 on the carrier. The carrier 32 is also provided with a point 38, which is adapted to engage with the thread of the screw 35 to connect the guide and screw, and so to cause the screw to move the guide and carrier along. The reference 39 denotes a horn connected frictionally with the carrier 32. The screw 35 is driven from the gear 13 by a reducing-train 40. When it is desired to run the speaker back, the carrier 32 is lifted until the point 38 is disengaged from the screw 35, when the guide and carrier may he slid back.

What I claim as new, and desire to secure by Letters Patent of the United States, is

1. A phonograph having its holder formed of springs fixed to a driving-gear.

2. A phonograph having its record-holder formed of leaf-springs fixed at the end to a driving-gear and looped inward and connected with the axis of said gear.

3. In aphonograph, a driving-gear, a shaft on which said gear rotates, and a record-holder formed of leaf-springs fixed to said gear and looped inward and rotatably connected with the shaft, in combination.

1. In a phonograph, a record-holder consisting of leaf-springs, a gear to which said springs are made fast, a shaft carrying said gear, and means for connecting said springs with said shaft, in combination.

5. In a phonograph, a drive-shaft, a beltpulley fast thereon, a drive-belt touching said pulley at one point only,a record-hold er geared to said shaft, and an automatic brake device, in combination.

6. The combination of atreadle-driven belt, a driven pulley to which said belt is practically tangent, and a phonograph driven thereby, with a brake device interposed between the belt and record-holder.

7 The combination of a driving-belt, a driven pulley to which said belt is practically tangent, and a phonograph driven thereby,

with an automatic brake device for regulating the speed of the phonograph.

8. In a phonograph, a belt-driven shaft, a collar fast on said shaft, a disk loose on said shaft, springs connecting said collar and disk, weights carried by said springs, and an adjustable brake normally disengaged from and against which said weights draw said disk, in combination with a record-holder actuated by said shaft.

9. In a phonograph, the combination with a feed-screw, a guide sleeved on said screw, and a reproducer-carrier slidable on said guide transversely to and adapted to be engaged with said screw.

10. In a phonograph, the combination with a feed-screw, a guide sleeved on said screw, a carrier movable on said guide transversely to and connectible and disconnectible to and from said screw, and a reproducer pivotally connected with said carrier.

11. In a phonograph, the combination of a feed-screw, a guide sleeved thereon and movable therealong, means for preventing rocking motion of said guide on said screw, a carrier slidable on said guide and thereby connectible and disconneetible to and from said screw, and a reproducer pivotally connected with said carrier.

12. In a phonograph, the combination of a frictionally-driven shaft, adisk movable along and rotating with said shaft, weights for moving said disk along said shaft, and a brake normally disengaged from and against which said weights draw said disk, with a recordholder actuated by said shaft.

Signed at New York, in the county of New York and State of New York, this 23d day of May, A. D. 1904.
