T 0 all whom it may concern:

Be it known that I, SOLOMON S. BENSTER, a citizen of the United States, residin at T0- ledo, in the county of Lucas and tate of Ohio, have invented certain new and useful Improvements in Repeating Attachments for Phonographs, of which the following is a specification.

The present invention comprehends generally improvements in phonographs and more particularly relates to a repeating attachment for phonographs.

It is the primary aim and object of this invention to provide a device of the above mentioned character designed to be attached to the stand, rotating spindle and sound reproducer of a phonograph for acting in conjunction with a record on the rotating table to ultimately insure of the repeating of the record as many times as desired.

As an additional and equally important object this invention contemplates the provision of a device of the above mentioned character, wherein the component parts are of novel construction and are relatively adjustable with respect to the stand and with respect to each other so as to permit of the playing of various sized records, and also, to permit of the removal of the records when desired.

More particularly, the present invention consists in the provision of a device of the above mentioned character wherein a record contacting roller is adjustably mounted on the tone arm and is designed to contact with the record while cooperative stop means is associated with the roller shaft and the supporting arm on the stand so that the roller will act at predetermined times to swing the tone arm into a set position. Furthermore cam means are provided for incidentally acting in conjunction withthe roller for raising the needle or stylus during the return movement of the tone arm.

The invention also embraces the provision of a device of the above mentioned character wherein the means for supporting and attaching the roller to the tone arm is of novel construction, the roller supporting frame being adjustable to vary the angular disposition of the roller with respect to the record grooves while the stop pins which are carried with the roller to coact with the sides of the frame are relatively adjustable so as to be properly arranged with respect to the counter-balance weight on the axle to ultimately insure of the proper adjustment of these parts on any sized record in consequence returning or shifting the tone arm so that the needle or stylus will be properly enga ed at the starting point of the record.

Among the other aims and objects of this invention may be recited the provision of a device of the above mentioned character with a View to compactness wherein the number of parts is comparatively few, the construction simple, the cost of production low and the efiicienoy high.

Other objects, as well as the nature, characteristic features and scope of this invention will be more readily apparent from the following description taken in connection with the accompanying drawings, and pointed out in the claims, forming a part of this specification.

The invention is clearly illustrated in the accompanying drawings, in which 2- Figure 1 1s a top plan view showing the attachment applied on aphonograph, only a portion of which is shown,

2 is a side elevation of the same,

Fig. 3 is an enlarged side elevational do tail of the roller and the supporting frame,

Fig. 5 is a fragmentary elevational detail of the means for mounting the supporting bar on the stand,

Fig. 6 is a fragmentary sectional detail of the means for supporting the opposite end of the supporting bar, and

Flg. 7 is a transverse sectional detail through the supporting bar showing one of the stops thereon.

Similar characters of reference are employed in all of the above described views, to indicate corresponding parts.

Referring now, more particularly, to the accompanying drawings there is illustrated a portion of a phonograph including a stand 1 having a top or platform 2 above which projects a vertically arranged rotating spindle for the revolving record carrying table 3 which is designed or adapted to support a record 4. A tone arm 5 is swingably arranged horizontally of. the top or platform 2 and is fitted with a sound reproducer 6 9 which is secured to the side of thestand beneath the platformof the cover as by fasteners 10, the upper portion being offset 7 as at 11 while swingably connected for vertical movement to the upper end of the offset portion 11 of the bracket 9 is the inner end of a slightly longitudinally curved supporting bar 12 the pivotal connection being maintained by a pintle 13. A bracket arm 14 is connected to the outer terminal of the bar 12 and terminates in a cap or socket 15 which is designed to be fitted about the upper end of the spindle while a screw 16 is mounted through the top of the cap or socket portion 15 for coacting with the upper end of the spindle and the bracket 9 in maintaining the bar 12 in desired spaced relation above the record. As the cap 15 is removable from the spindle and as the bar is swingably connected for' vertical movement, it is apparent that the same may be swung upwardly when it is desired to re place the record. Stop members 17 and 18 are formed with sleeved portions which are slidably arranged on thebar 12 near the respective ends thereof as indicated for a purpose that will presently appear.

Coacting with the supporting bar 12 and the stops 17 and 18 thereof is the record engaging means designed for swinging the tone arm 5 sothat the needle will be in a starting position immediately subsequent to the completion of the record. In the present instance there is'provided a bracket arm 19 the inner portion of which is curved arcuatelyto provide a stationary clamping jaw 20 to the outer end ofwhich is pivoted as at 21 a movable clamping jaw 22 also of an arcuate configuration while the clamping screw 23 isarranged through the outer end of the movable jaw 22 and adjustably engaged through the arm 19 and tightened subsequent of course to arranging the jaws about the outer portion of the tone arm. An inverted U-shaped supporting frame 24 is now provided and is clamped to the under surface of the outer end of the arm 19 by means of a suitable clamping element such as a screw 25; this arrangement permitting of theframe being positioned at various angles with respect to the arm 19 for a purpose that will presently appear. The frame 24 supports a roller 26 which is rotatably and necessaeccentrically mounted therein and designed to at times contact with therecord for returning the tone arm so that the needle will be positioned at the starting point of the record.

In reducing the present construction to' actual practice, the roller preferably consists of an annular body 27 having a grooved periphery to receive a rubber tire 28 for protecting the. record against injury. The annular body 27 is arranged about a concentric journaling portion 29 which projects from one face of a disk 30, the outer j ournal ing portion being reduced as at 31 while the journaling portion and the disk are provided with a bore 32 in which is frictionally engaged an axle 33 the outer end portions of which are journaled through bearings 34 at the lower ends of the frame 24. 'Another annular band 35 is frictionally engaged on the reduced end 31 of the journaling portion 29 lying flush with the outer ends of the reduced portion so as to form a substantial disk. The engagement between this annular member or band 35 is frictional the same as the engagement of the annular member 27 in the journaling portion 29, this arrangea ment permitting of the arranging of the .so as to be positioned as shown in Fig. 3,

to hold the pin 36against the adjacent side of the frame when the roller or wheel is ar ranged in close relation with the same side of the frame, while in addition one of the principal purposes of this weight is to cause the roller to engage the disk immediately subsequent to the shifting of the axle in a manner that will hereinafter become apparent and consequently return the tone arm to a starting position. In this connection it is to be particularly understood thatthe disengagement of one or the other of the pins 36 is effected when the device comes in contact with the stop members 17 or 18. In returning these parts to the position described or in other words setting the tone arm so thatthe record may be repeated a bracket arm 39 extends from the opposite side and has pivoted thereto a horizontally swinging stop arm 40 for coacting with the stop 18, said stop arm 40 carrying a concaved disk 41 to act against the convex head 42 formed on the oppositely projecting extremity of the shaft 33. In this connection it is to be particularly understood that sub sequent to the release of the inner pin 36 from the adjacent side of the frame 2st which is effected by the contact of the weight 38 with the stop 17, the roller 26 owing to the peculiar positioning of the weight 38 moves downwardly and engages the record and inasmuch as the frame 2% is arranged at an angle to the disk the said. roller will revolve and carry the tone arm toward the outer edge of the record; when near the outer end or starting point of a record the stop arm 30 strikes the stop 18 so the disk 40 will in turn strike the head 42 and shift the shaft releasing the opposite pin 36 from the adjacent side of the frame, the counter-weight on the shaft in the meantime assuming a position slightly over the center so that immediately subsequent to the disengagement of the last mentioned pin 36 the weight will act to raise the roller from the record and will in turn be held against further downward movement by the re'c'ngagement of the pin 36 with the frame. The needle of course engages the starting point of the record immediately subsequent to the raising of the roller from the record by the counterweight. It will thus be seen that the tone arm and needle are in position to repeat the record and it is equally well apparent that owing to the particular arrangement of the repeat ing attachment or repeating mechanism that the parts will be automatically adjusted to again reset the mechanism as soon as the counterweight strikes the stop 17.

It it believed in view of the foregoing description that a further detailed description of the operation of the invention is entirely unnecessary. Likewise, it is believed that the advantages of the invention will be readily apparent. However, in this connection it is to be particularly understood that owing to the connection of the frame 24 with the arm 19 and the relatively adjustable pin 36 as well as the adjustable stops 17 and 18 that various sized records may be played and repeated for as many times as desired.

Still further embodiments of the invention than those herein especially defined may be resorted to as conditions or preference may dictate, as may be in keeping with the hereto appended claims.
