PHONOGRAPHIC REPEATING MECHANISM;

SPECIFICATION forming part of Letters Patent No. 744,267, dated November 17, 1903.

Application filed April 14, 1903.

To all whom it may concern:

Be it known that I, PETER WEBER, a citizen of the United States, residing at Orange, in the county of Essex and State of New Jersey, have invented a certain new and useful Improvementin Phonographic Repeating Mechanism, of which the followingis a description.

My invention relates to various new and useful improvements in phonographic repeating mechanism by means of which the reproducer may be returned toward its starting position to the extent of a few threads, whereby a part of the record may be repeated.

The improvements are particularly designed for use in connection with phonographs intended for the study of languages or when phonographic dictation is to be transcribed.

My object is to provide a simple and efficient device for the purpose and one which can be readily applied to existing types of phonographs and other talking -.machines. At the same time the device is neat and attractive in appearance.

Broadly considered, the invention consists in pivoting a toothed bar in such relation to the reproducer or its supports that by tilting j the-bar the reproducer will be elevated from the record and the feed-nut will be simultaneously disengaged from the feed-screw, whereby the reproducer will be free to be carried longitudinally of the record and independent thereof, and in combining with such a toothed bar a cam mechanism whereby the tilting of the bar results in a longitudinal shifting thereof, so as to move the reproducer toward its starting position to the extent of a few threads.

In order that the invention may be better understood, attention is directed to the accompanying drawings, forming a part of this specification, and in which- Figure 1 is a plan view of a phonograph of common type with my present improvements applied thereto, the shield for protecting the feed-screw being shown in section; Fig. 2, a sectional View on the line 2 2 of Fig. 1; Fig. 3, an enlarged detailed view of the cam-head and pin for shifting the toothed bar looking Serial No. 152,484. (No model.)

in the direction of the arrow in Fig. 1; Fig. 4, a section on the line 4 4 of Fig. 1; Fig. 5, a section on the line 5 5 of Fig. 1; Fig. 6, a view similar to Fig. 4, showing the toothed bar in its tilted position; and Fig. 7, a front elevation showing the toothed bar in its tilted position and moved to the full extent of its retracted movement.

In all of the above views corresponding parts are represented by the same referencenumerals.

The phonograph shown in the drawings is provided with the tapered mandrel l, the reproducer 2, carried by the arm 3, slidably and pivotallymounted on the back rod 4 and having an antifriction-roller 5, working on the front bar 6, the feed-screw'7, and the feed-nut 8, engaging the feed-screw and carried by the reproducer-supporting arm 3, all as heretofore. In applying my improved attachment to aphonograph of this type I first form a series of serrations or teeth 9 on the under face of the front end of the supporting-arm 3, as shown. Secured to the front bar 6 are two brackets 10 10, in which is mounted a shaft 11, carrying a toothed bar 12, located normally immediately below and parallel with the serrated face of the arm 3. Preferably the teeth on the bar 12"are out on a bevel, as shown in Fig. 6, so that when the bar is moved to its inclined position its teeth throughout their width will engage the teeth on the arm 3. The brackets 10 are spaced somewhat farther apart than the length of the toothed bar 12, so as to permit of longitudinal movement of said bar in operation.

In order to tilt the bar, I provide its shaft at one end with a small finger-lever 13. On the opposite end of the shaft 11 I secure a cylindrical head 14, formed with an inclined cam 15, (see Fig. 3,) and cooperating with this cam is apin 16,projecting from the adjacent supporting-bracket 10. When the shaftllis partially rotated, the cam portion 15 does not engage the pin 16 until the toothed bar 12 has been tilted sufliciently to elevate the reproducer-stylus from the record, as well as to disengage the feed-nut 8 from the feed-screw 7. A spiral spring 17 extends between the toothed bar 12 and the phonograph-frame and serves not only to return the toothed bar to its horizontal position, but also to return the bar laterally when the bar has been shifted to one side (see Fig. '7) by the operation of the cam mechanism. When the toothed bar is in a horizontal position, it engages one or both of brackets 10, which therefore act as limiting-stops.

In operation when it is desired to repeat any phonographic matter the finger-piece 13 is depressed, so as to tilt the toothed bar 12, which engages the toothed face of the arm 3 to lift the stylus from the record and to disengage the feed-nut 8 from the feed-screw 7. The cam 15 now engages the stationary pin 16 and moves the bar 12 to one side for the distance of several threads. In this movement the finger of the operator will follow the finger-piece l3. Whenthe finger-piece 13 is allowed to return to its normal horizontal plane, the natural inclination of the operator is merely to elevate the finger and not to also move it to one side. Consequently the toothed bar does not reverse its longitudinal movement and deposit the stylus at the point where the stylus left the record; but the toothed bar is first moved directly to its normal horizontal position, so as to engage the styluswith the record at a point several threads behind the point where the stylus left the record, after which when the operators finger is released the spring 17 moves the toothed bar longitudinally to its original position. In this way I have produced a repeating mechanism which has been entirely successful in actual practice and wherein I have dispensed with the necessity for complicated mechanism to cause the toothed bar in its return movements to be positively operated and deposit the stylus on the record in a ditferent line from which the stylus left the record.

Having now described my invention, what I claim as new therein, and desire tosecure by Letters Patent, is as follows:

1. In repeating mechanism for talking-machines, the combination with the reproducer, feed-screw, and feed-nut, connected with the reproducer and engaging the feed-screw, of a pivoted toothed bar arranged to move longitudinally, and when moved pivotally to elevate the reproducer and disengage the feednut from the feed-screw, and cam mechanism for shifting the toothed bar longitudinally when the bar is moved pivotally, substantially as set forth.

2. In repeating mechanism for talking-machines, the combination with the reproducer, feed-screw, and feed-nut connected with the reproducer and engaging the feed-screw, of a pivoted toothed bar removably carried by the talking-machine, and arranged to move longitudinally and when moved pivotally to elevate the reproducer and disengage the feed-nut from the feed-screw, substantially as set forth.

3. In repeating mechanism for talking-machines, the combination with the reproducer, feed-screw, and feed-nut connected with the reproducer and engaging the feed-screw, of a pivoted toothed bar cooperating with the reproducer, and means for first tilting the toothed bar to elevate the reproducer and disengage the feed-nut from the feed-screw, and for then shifting the toothed bar longitudinally, carrying the reproducer therewith, substantially as set forth.

4. In repeating mechanism for talking-machines, the combination with the reproducer, feed-screw, and feed-nut connected with the reproducer and engaging the feed-screw, of a pivoted toothed bar arranged to move longitudinally and when moved pivotally to elevate the reproducer and disengage the feednut from the feed-screw, a cam carried by the toothed bar and a pin with which said cam cooperates, whereby, after the toothed bar has been first elevated, it will be shifted longitudinally, carrying the reproducer therewith, substantially as set forth.

5. In repeating mechanism for talking-machines, the combination with the reproducer, feed-screw, and feed-nut connected with the reproducer and engaging the feed-screw, of a pivoted toothed bar, removably carried by the talking-machine, and arranged to move longitudinally and when moved pivotally to elevate the reproducer and disengage the feed-nut from the feed-screw, and a single spring for etfecting return movements of the toothed bar, both pivotally and longitudinally, substantially as set forth.

6. A repeating attachment for talking-ma chines,comprisinga pair of bearings arranged to be secured to the talking-machine,a toothed bar mounted in said bearings, a cam-head on the shaft of said bar, and a pin carried by one of the bearings and cooperating with the cam-head, substantially as set forth.
