REPEATING ATTACHMENT FOR PHONOGRAPHS.

SPECIFICATION forming part of Letters Patent No. 722,616, dated March 10, 1903.

Application filed June 19,1902. Serial No. 112,350. (No model.)

To all whom it may concern:

Be it known that I, DAVID PETRI-PALMEDO, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented new and useful Improvements in Repeating Attachments for Phonographs, of which the following is a specification.

This invention relates to an attachment for sound recording and reproducing machines; and the object of the invention is to provide simple mechanism for easily and conveniently repeating portions, such as single words or short sentences or a single bar or fugue of a I5 recorded speech or a piece of music, respectively.

The invention in one simple and convenient embodiment thereof is shown in the accompanying drawings,forming a part of this speci- 2o fication, and in which- Figure 1 is a side elevation of certain of the parts of an Edison phonographembodyin g my improvements. Fig. 2 is a front elevation of the same.

Like characters refer to like parts in both figures of the drawings.

I have shown in the drawings a simple organization of parts for the purpose of representing the character of the invention, and by the same in order to repeat any part of a record upon the cylinder of the instrument the feed-screw mechanism must be temporarily disengaged, the speaker or reproducing-diaphragm must be lifted from the record, and the reproducing-stylus set back a certain distance. The reproducingpoint must be brought in contact with the record again and the feed mechanism put in cooperative relation therewith. These functions I accomplish by a single motion of the hand, as will be clear from the following description of my attachment.

In the drawings, A represents the mandrel of an Edison phonograph; B, the wax cylinder upon which sound is recorded.

Ois the so-calledspeaker-arm, that carries the speaker,with its diaphragm and reproducing-point I. This speaker-arm is guided at one end on a rod D, and at the other end it to the rear endof the speaker-arm, engages a feed-screw H, which being actuated by a spring-motor causes the speaker-arm to travel laterally across the record; but when the speaker-arm is lifted from the ledge E the feed-screw and feed-nut G and H are disengaged, allowing the speaker-arm to be shifted back and forth on the guide-rodD independently of the feed mechanism.

All of the foregoing description pertains to the well-known apparatus of the Edison phonograph, and my improvements are shown incorporated therein.

For repeating single words, short sentences, &c., I provide'a hinge K, having wings or pieces L and L, by means of which it rides on the ledge E of the phonograph. Two projections M and N are provided to the lower part of the hinge. Between these stops fits the projecting lug X of the speaker-arm with a clearance. On the upper half of the hinge is provided a small antifriction-roller O, that rests against the circular portion of the speaker-arm, containing the reproducing-diaphragm, or the so-called speaker-ring. Ber tween the two halves of hinge K, I place a small elastic rubber bag R, which is connected by a rubber tube Q with an elastic bulb B. On pressing the bulb R the rubber bag is inflated, the upper part of the hinge/is lifted up, and in turn lifts the speaker-arm from the ledge E. Next by its own weight the speaker-arm slides down upon the antifriction-roller O and to the left against the stop M. On releasing the pressure on the bulb R the feed mechanism is again engaged, and the speaker-arm is again caused to ad- Vance by virtue of the feed mechanism. The

lug is caused to travel from the projection M toward the projection L, then takes the whole hinge along with it, and at any time that a repetition of a word or sentence, 860., is desired the speaker-arm can be set back a small distance by pressing on the bulb R in the manner thus described, thus causing the diaphragm to repeat. The wings L and L frictionally hug or straddle the ledge or rail E of the frame to a degree sufficient that when the attachment is at rest and the sound-reproducing device is moved backward in the manner indicated the projection M when engaged by the lug X will resist or stop further backward motion of said sound-reproducing device.

The invention is not limited to the construction hereinbefore set forth, the same being shown and described simply for the purpose of indicating the nature of my improvement, for many variations in the form and arrangement of parts may be made within the scope of the accompanying claims. It will be also understood that the attachment is not limited in its application to any particular kind of sound recording and reproducing in- V strument.

Having described the invention, what I claim is- 1. The combination of a sound-record, a sound-reproducing device cooperative therewith, feed mechanism for advancing the son nd-reproducing device, a member movable with the sound-reproducing device and having a projection, mechanism for throwing the sound-reproducing device out of cooperative relation with its feed mechanism, and cansing the retraction of the same until it abuts against said projection.

2. The combination of a sound-record, a sound-reproducing device cooperative therewith, feed mechanism for advancing the sound-reproducing device, a member movable with the sound-reproducing device and havinga pairof projections, a lug upon the soundreproducing device disposed between said projections, and mechanism for throwing the sound-reproducing device out of cooperative relation with its feed mechanism, and causing the retraction of the same until'it abuts against one of said projections.

3. The combination of a sound-record, a sound-reproducing device cooperative therewith, feedmechanism for advancing the sound-reproducing device, a hinge cooperative with the sound-reproducing device and one of the parts of the hinge carrying an antifriction-roll adapted to engage an inclined surface upon the sound-reproducing device, and the other part of the hinge having a pair of projections, a lug upon the sound-reproducing device disposed between the said projections, and means for operating that part of the hinge which carries said antifrictionroll, relative to the companion member of said hinge.

4. The combination of a sound-record, a sound-reproducing device codperative therewith, feed mechanism for advancing the sound-reproducing device, a hinge cooperative with the sound-reproducing device, and

one of the parts of the hinge carrying an antifriction-roller adapted to engage an inclined surface upon the sound-reproducing device and the other part of the hinge having a pair of projections, a lug upon the sound-reproducing device disposed between the said projections, an inflatable bag between the members of said hinge, and a tube connected with said inflatable bag, and provided with a bulb.

5. The combination of a sound -record, a sound reproducing device cooperative therewith, feed mechanism for advancing the sound-reproducing device, a member movable With the sound-reproducing device and having a projection, mechanism for throwing the sound-reproducing device out of codperative relation with its feed mechanism, and cansing the retraction of the same until it abuts against said projection, and including a single manually-controlled device for securing the operation specified.

6. The combination of a sound-record, a

sound-reproducing device having a rounded surface, feed mechanism for advancing the sound-reproducing device, a movable memher having a projection to engage said rounded surface, 'means for actuating said movable member to cause the same to throw the soundreproducing device out of operative relation with its feed mechanism and toalso cause the retraction of said sound-reproducing device, and a projection adapted to be engaged by the sound-reproducing device on its retractive movement.
