NEWV JERSEY, A CORPORATION OF REPEATING ATTACHMENT FOR PHONOGRAPHS.

SPECIFICATION forming part of Letters Patent No. 771,851, dated October 1 1, 1904.

Application filed October 1, 1903- To all whom, it may concern:

Be it known that 1, PETER WEBER, of Orange, in the county of Essex and State of New Jersey, have invented certain Improvements in Repeating Attachments for Phonographs, of which the following is a description.

My invention relates to various new and useful improvements in repeating attachments for phonographs, either in connection with those instruments in which the record is to be repeated indefinitely or in connection with those instruments in which the motor is controlled by dropping a coin in the slot and wherein it is necessary that the reproducing device should automatically be returned to the commencement of the record ready for anew reproduction.

The object of my invention is to provide a simple and improved apparatus for the purpose, one which can be readily applied to phonographs or allied talking-machines of existing types without detracting from the appearance of the latter and which shall be simple in construction and entirely certain in its operation.

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 special improvements attached thereto, the reproducer-horn being removed for purposes ofclearness; Fig. 2, a front elevation of the same; Fig. 3, a front elevation of the tripping mechanism in the position which it occupies during the reproduction; Fig. I, a view taken at right angles to Fig. 3, showing the same parts; Fig. 5, a view corresponding to Fig. 3, illustrating the parts of the tripping mechanism after a tripping operation has taken place and before the reproducer begins its return movement; Fig. 6, a View taken at right angles to Fig. 5, showing the same parts in the same position; Fig. 7, a front elevation of the tripping mechanism, illustrating the same as having just been returned to its operative position,which Serial No. 175,402. (No model.)

action takes place during the return movement of the reproducing devices; Fig. 8, a view taken at right angles to Fig. 7, showing the same parts in the same position; Fig. 9, a front elevation of the tripping devices in the position which they occupy when the re- 7 producer commences to move to again effect a reproduction of the record; and Fig. 10, a view taken at right angles to Fig. 9, showing the same parts in the same position.

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

The phonograph shown in the views is of a common type, being provided with a mandrel l, a back rod 2, on which travels a sleeve 3, to which is secured the arm at, carrying the eye5, in which are mounted the usual reproducing devices, said sleeve being also provided with a spring-arm 6, carrying a nut on its end which engages with the usual feedscrews 7 Projecting outwardly from the eye 5 is the extension 8, which travels on the usual front bar 9 of the phonograph. The mandrel 1 is driven from a pulley 10 from anysuitable motor. (Notshown) \Vhen the repeating attachment is to be used for effecting an indefinite repetition of a given record, this motor may be stopped and started by the usual manually operated devices; but when the attachments are to be used in connection with sound reproducing machines which are adapted to be controlled by 'thei'ntroduction of a coin in a slot suitable and appropriate mechanism is to be used for effecting the stopping of the motor at the proper time. Mechanism of this latter type is well known to skilled persons in this art and requires no detailed description here. Mounted in a suitable bearing behind and somewhat below the feed-screw 7 is a return-shaft 11, having a thread of great pitch cut therein, so that the reproducing devices will be very rapidly returned to the starting position at the proper time. This return-shaft is operated in any suitable way-as, for example, by means of a light chain 12 passing over a sprocket-wheel 13 on the shaft of the feedof the reproducing devices, when the reproducer is elevated from the record and the 4 feed-nut is simultaneously disengaged from the feed-shaft 7. Secured to the extension 8 of the phonograph-arm 4 is a plate 17, having a downwardly-extending front portion 18, formed with a bifurcated lower end, as shown, one arm, 19, forming an anchor for the lower extremity of a spring and the other, 21, being provided with an inturned finger 22, which performs important functions in the operation of the devices, as will be presently described. Mounted on the back side of the plate 18 is a lever 23, having a downturned tail 24 at its end. Secured to this lever near one of its free ends is a pin 25, which is adapted to engage the front bar 9 of the phonograph to elevate the reproducer from the record after the latter has been reproduced and simultaneously elevate the feed-nut from the feed-screw 7 and en gage the pin 16 with the return-screw 11'. The lever 23 is normally locked in position to maintain the pin 25 out of engagement with the front bar 9, by means of a trip-arm 26, having a notch therein, as shown, which normally engages the adjacent edge of the plate 17.

In order to actuate the trip-arm so as to free the lever 23 after the record has been reproduced, I make use of a releasing-rod 27, which is arranged in the path of travel of the trip-arm as the latter moves with the reproducing devices. This releasing-rod 27 is supported in an eye 28, carried by a bracket 29, which is removably secured to the front of the phonograph, and said releasing-rod is locked in any position of adjustment in said eye by a thumb-screw 30, as shown. By varying the position of the releasing-rod in its support it will be evident that the trip-arm 26 can be actuated at any position of the operative stroke of the reproducing devices, whereby the return mechanism can be brought into operation to return the reproducing devices to the starting-point immediately after the record has been reproduced. The spring 20 connects with the free end of the lever 23, so that as soon as said lever is released by the trip-arm 26 the spring will move the lever pivotally to engage the pin 25 with the front bar 9 of the phonograph and elevate the reproducer from the record. In order to reset the lever 23 during the return movement of the reproducing devices, I make use of a resetting-arm 31, which is pivoted to said lever and which is provided with a pin 32, engaging the tail 24, as shown. On the return movement of the reproducing devices the resetting-arm 31 engages a pin 33, carried by a plate 34, as shown. This plate is provided with a slot 35 therein, within which are mounted the screws 36 for holding the plate removably and .adjustably in position on the front of the phonograph. By adjusting this plate in one direction or the other the reproducing devices may be made to engage the record at any point thereon. By thus employing adjusting mechanism for determining the time at which the reproducer shall engage the record as well as the time when the reproducer shall leave the record I secure a device in which no time is lost in the operation, since the parts can be adjusted to engage the reproducer with therecord at the exact commencement thereof and to disengage the reproducer from the record at the exact conclusion thereof.

The linger 22 is so located with reference to the plate 34 as to be supported by said plate during a part of the return movement of the reproducing devices, so as to still hold the latter out of engagement with the record, while during the operating movement of the reproducing devices in effecting a reproduc; tion of the record the finger 22 travels beneath said plate 34 and out of engagement with the same, as will be explained.

The operation of my improved mechanism will be readily understood. is to say, when the reproducing devices are in engagement with the recordthe lever 23 will be locked in its operative position by means of the trip-arm 26, the pin 25 being just out of contact with the front bar 9, although it will of course be understood that, if desired, the arm 4 can be supported at its free end at all times by means of the pin 25; but such an arrangement is not a desirable one. In the operative position of the parts the finger 22 will be located in line below the plate 34, as shown in Figs. 9 and 10. In effecting a reproduction of the record the phonograph operates in the usual way, the feedscrew 7 moving the reproducing devices laterally at the desired pitch, and in this lateral movement the finger 22 will travel beneath the plate34. As the reproducing devices approach the end of the record the trip-arm 26 Normallythat IIO will engage the releasing-rod 27, and said arm will be tripped at the proper time, thereby freeing the lever 23 and permitting the spring 20 to operate the same pivotally, thus engaging the pin 25 with the front bar 9 of the phonograph, elevating the reproducing devices from the record, releasing the feed-nut from the screw 7, and engaging the pin 16 with the return-screw 11. The position of the parts immediately after the arm 26 has been tripped is shown in Figs. 5 and 6 of the drawings.

or the parts rotating by the momentum, the return-screw 11 will cause the reproducing The motor continuing to operate devices to partake of a return movement, the arm 4 being now supported by the pin 25 of the return mechanism. On the return movement of the parts the resetting-arm 31 will engage the pin 33, thereby tripping the lever 23 to its original position, or somewhat beyond that position, causing the notchon the trip-arm 26 to again engage the edge of the plate 17 to once more lock the lever 23 in its normal position. When the resetting-arm 31 leaves the pin 23, the finger 22 drops upon the plate 34 and still holds the reproducing devices in a withdrawn or elevated position free of the record. From this point, therefore, to the commencement of the record the reproducing devices will be sustained in their elevated position by the finger 22 traveling on the plate 34, as will be understood. When the finger 22 reaches the end of said plate, it drops off therefrom and permits the reproducing devices to again engage the record,the feednut being again engaged by the feed-screw 7 and the pin 16 being withdrawn from the return-screw 11. By adjusting the position of the plate 34 it will be seen that the finger 22 may be caused to leave the same at any desired position with respect to the record, whereby the reproducing devices may be caused to engage the same at any desired point thereon. During the operative movement of the reproducing devices the resetting arm 31 again engages the pin 33; but in this movement the pin 32 will be moved away from the tail 24, so that the movement of the resetting-arm will not affect the position of the lever 23.

The device is extremely simple in construction and operation, as will be seen, and has been found to be entirely certain and reliable in practical use.
