FEEDING MECHANISM FOR SOUND-BOXES.

Application filed October Be it known that I, \Vnmmu \V. Zaonnr, a cit zen of the United States, residing in the city and county of lhiladelphia, State of Pennsylvania, have invented a new and useful Fecdmg Mechanism for Sound- Boxcs, of which thefollowing is a specification.

This invention relates to an improvementin sound recording and reproducing machines and relates more particularly to a mechanism for causing the sound lack of such a machine to move across 'the face of a sound record independently of andin unison with the movement of the groove of the record.

In machines of this character as heretofore constructed, it has been customary for the sound box to be driven or fed across the record by the grooving therein, the result of which has been a wearing away of the sound wave impressions causing notonly a gradual loss of tone quality but also a scratching sound and other unpleasant noises to mar the tone produced.

Figure 1 represents a sect-ional elevation of a machine embodying my invention. Fig. 2 represents a section on linen-01; Fig. 1. Fig. 3 representsa plan of Fig. 1.

For the purpose of illustrat-ingmy invention, I have shown in the accompanying drawings one form thereof which is atresent preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention'is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates the casing of asound reproducing machine the same having a motor 2 therein of the usual construction of which 3 designates a driving gear to which in the present instance, I preferably connect my novel oper- Iaiting means for the movement of the sound t-"designates the sound box carryin theusual needle 5 and secured by a ivota con- I nection (5 to the supporting tubu ar member Specification of Letters Patent.

7 'This arm 7 is movably attached to a suitable bracket 8 and positloned to receive the amplifying horn, as will be readily-understood, the attaching means preferred cousistlng of a swinging joint 9 in order that the arm 7 may be moved readily over the record or swung to one side as the case may be.

10 designates a belt provided in the present instance with perforations 11. adapted to engage the teeth. 12 of a pinion 1? suitably mounted upon a spindle lei secured in standards 15. These standards 15 are secured in any suitable manner to the casing l and form with a. set mld pair of standards 16 a supporting framework in which the belt 11) is mounted and suitably guided by means of the rotatably mounted guide wheels 17. as will be apparent. The belt 10 is positioned adjacent and preferably beneath the arm 7 so that as the latter rests thereon the friction' between the two is sutiicieht' to carry the arm v7 across the face of a record with the movement of the belt, the travel of the box 4 being substantially synchronous with the sound waves of the groove of the record.

Any suitable gearing may he provided for driving the spindle 1+ to actuate the belt 10 it. being 0. course.understood that the gearing must e so designed and constrm-ted as to producean exact and accurate movement of the belt-10. As here shown, the gearing consists of a pinion 18 suitably mounted upon the spindle 14 and in mesh with a gear 19 'rotatabl y mounted on the casing and havingsecured. thereto a second gear 20 which is in mesh with a pinion 21 likewise rotatably mounted upon the casing 1 and having socured thereto a gear 22 cooperating with the pinion 23 to receive motion from the gear 24. which is driven through the medium of a pinion 25 from the gear 3.

It will of course be apparent that the record spindle 26 is driven from the motor 2.at a certain speed and in order that the needle 5 of the sound box travel in coincidence with the sound groove a very careful and exact adjustment of theseveral gears 18 to 25 inclusive must be made in order to transmit suitable movement to the belt 10.

Itwill be seen that the movement of the belt 10 is necessarilya very slow one and the friction due to the weight of the arm 7 is suflicient to carry the latter along with the belt 10 and over the face of the record with while the unpleasant noises usually given out are substantially done away with. I

It will now be apparent that I have devised a complete unitary structure well adapted for the purpose intended and which is'simple in operation and construction, eliminates substantially all of the wear upon the sound record, reduces the scratching and drag of the :needle and gives a clear, pure tone with a maximum of volume.

It will now be apparent'that I have devised a novel and useful construction which embodies .the features of advantage enumerated as desirable in the statement of the invention and the above description and while I have in the present instance shown .and described a preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by LettersPatcnt, is l 1. In a sound recording and reproducing machine, an arm suitably-mounted for swing.- ing movement, a sound box carried by said arm, a belt suitably mounted to support said arm, a motor, and driving means between said motor and belt. I

2. In a sound recording and reproducing machine, an arm suitably mounted for swinging movement, a sound box carried by said arm, a belt suitably mounted to support sound box carried by said am, a framework carried by said casing, a plurality of uide wheels rotatably .mounted in said ramework, a belt contacting with said guide wheels and positioned to'support said arm, a motor, and driving means between. said motor and said belt.

4. In a sound recording and reproducin machine, a casing, an arm sultably mounte for swinging movement relative thereto, a

sound boa carried by said arm, a framework carned by said casing, a shaft in said framework, a gear carried by said shaft, a plurality of, uide wheels mounted in said framework a j acent said gear, a belt having a plurality of openlngs'therein adapted to engage said gear and passing over said guide wheels, a motor, and means between said shaft andlmotor to drive said shaft at a-predetermined speed.

5. In a sound recording and reproducing machine, a casing, an arm suitably mounte 1 for swinging movement relative thereto, a sound box carried by said arm, a frame work carried by said casing, a shaft in said,

framework, a gear carried by said shaft, a

framework adjacent said gear, a belt having a plurality of openings therelnadapted to engage said gear and passing over said guide wheels, a motor, and means between said shaft and motor to proportion the movement of said belt relative to the turning movement of a sound record driven by said motor.
