HILMER NELSON, OF MARVINDALE, PENNSYLVANIA.

EEPEATING MECHANISEI FOR PHONOGRAPHS.

Application filed January 26, 1920.

To a'ZZ whom it may concern.

Be it known that I, T-TIL-MER NELSON, subject of Sweden, residing at Marvindale, in the county of McKean and State of Pennsyl- 5 vania, have invented certain new and useful Improvements in Repeating Mechanism for Phonographs, of which the following is a specification.

This invention relate to phonographs,

and the primary object of the invention is to provide an improved attachment for phonographs which will permit the replaying of the record when so desired by the operator.

Another object of the invention is to provide an improved means for returning the tone arm and its reproducer and stylus to its starting point on the record after the selection has been played so as to permit the repeating thereof automatically, without any attention from the operator.

A further object of the invention is to provide an improved repeating attachment for phonographs, which can be adjusted to accommodate various sized records and thereby permit the playing of any length piece and the repeating thereof in correct time.

A further object of the invention is to provide an improved repeating attachment for phonographs which is so constructed as to permit the easy placing of the stylus or needle on the record tablet for the replaying of the selection without the marring of the record or the breaking or dulling of the stylus.

A still further object of the invention is to provide an improved repeating attachment for phonographs of the above character which is durable and eflicient in use, one that is simple and easy to manufacture, and one 410 which can be placed upon the market at a reasonable cost.

Other objects of the invention will appear in the following detailed description taken in connection with the drawings, forming a part of this specification, in which drawings:

Figure 1 is a fragmentary plan view of a phonograph showing the improved attachment applied thereto, the turn table being broken away and the operating shaft or center pin shown in section.

proved attachment applied thereto, parts of the same being shown in section.

Figure 3 is a fragmentary detail perspective view of the lever carried by the tone arm, and the operating disc therefor, showing the resilient connection between the same.

Figure 4 is a fragmentary plan view of the phonograph attachment, showing the tone arm being returned to its starting position, and the relation of the means carried by the tone arms with the resilient means carried by the operating disc.

Figure 5 is a rear elevation of the attachment.

Figure 6 is a detail section taken on the line 66 of Figure 1.

Figure 7 is a detail section taken on the line 77 of Figure 1. Figure 8 is a detail section taken on the line 88 of Figure 1.

Figure 9 is a detail section taken on the line 9-9 of Figure 1, and

Figure 10 is a detail transverse section taken on the line 1G10 of Figure 1 through the tone arm.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A indicates the improved repeating attachment for the phonograph which may be of the ordinary or any prefered construction, and as shown includes the tone arm 13, the reproducer C and the operating shaft or center pin D.

The tone arm B is swivelly connected to the frame of the phonograph (not shown) in the ordinary or any preferred manner and is made in a pair of sections 15 and 16, which are pivotally connected together by means of pivot pins 17. This permits the reproducer C to be lifted above the surface of the record (not shown) so as to permit the placing of the stylus in the sound groove. The outer section 16 of the tone arm B rotatably receives the hollow angle arm 18 of the reproducer and the section 16 is provided with a slot 19 for the reception of the screw 20 carried by the angle arm. The screw 20 has threaded thereon the ad 'justi ng nut 21, which is adapted to bind against the outer surface of the section 16.

The improved attachment A includes an operating lever 22, which is pivoted intermediate its ends on a pin 23 carried by the depending bracket 24 formed on the lower surface of the tone arm section 15. The outer end of the operating lever 22 is curved slightly upwardly towards the angle arm. 18 of the reproducer C and carries the pivoted yoke 25, which is adapted to engage the angle arm 18, for a purpose which will be hereinafter more fully described. The pivoted yoke 25 is normally held in its operative position for engaging and supporting the angle arm 18 by means of a leaf spring 26, which is secured to the lever 22 and engages the lower surface of the yoke which is provided with a lug 27 for engaging the forward surface of the spring to limit the swinging movement thereof. The forward end of the operating lever 22 is slotted for the reception of the yoke 25, and the same is adapted to swing downwardly into engagement with the upper surface of the lever when the attachment is not to be used.

The tone arm section 15 directly in rear of the bracket 24 is provided with a slotted depending guide 28, which forms means for holding the lever 22 in its correct positions. The lever 22 in rear of the guide 28 is provided with a. depending arm 29, which is provided with oppositely extending right angularly disposed spring fingers 30, which are adapted to engage the pins 31 and 32, carried by the upper surface of the operating disc 33. The pins and 32 are arranged adjacent to the periphery of the disc and the pins 32 are arranged nearer to the central axis of the disc than the pins 3-1 for a purpose which will be hereinafter more fully described. The operating disc is rotatably mounted upon the upper surface of the cabinet of the phonograph directly below the turn table (not shown), in such a manner that only a portion of the same projects outwardly from the turn. table. The operating disc 33 is rotated from the operating shaft or center pin D which has a. pulley 34 mounted thereon. The pulley 34 has trained around the same a belt 35, which drives the relatively small disc The relatively small. disc 36 and the disc 33 are connected together by a suitable belt 37. The addition of the wheel 36 forms means for reducing the speed of rotation of the operating disc 33 in relation to the turn table. The outer edges of the discs 33 and 36 are provided with peripheral grooves 38 for the-reception of the drive belts and 37. The resilient fingers 30 are adapted to be normally held above the surface of the pins 31 and 32 but when the inner end ofthc lever is lowered by means hereinafter more fully described. the pins engage the spring fingers and swing the tone arm over the turntable. The inner end of the operating lever 22 is curved outwardly as at 39, so as to conform to the configuration of the tone arm B and the extreme inner end is provided with a weight 40* which tends to counterbalance the weight of the tone arm section 16 and the reproducer 0.

Immediately in rear of the operating disc 33 and in front of the point of connection of the tone arm B with the cabinet, an arcuate base plate 41 is arranged on the upper surface of the phonograph by suitable fastening elements. The upper surface of the ase plate 41 has secured thereto the arcuate guide tracks. 42 in which is slidably mounted the arcuate vertical adjusting'plate 43. The lower end of the arcuate vertical adjusting plate 43 is provided with a right angularly extending base 44, which is mounted .in the guide tracks. The upper edge of the plate 43 intermediate its ends is provided with inwardly extending spaced right angularly extending lugs 45, and 46. The lug 46 isformed relatively wider and broader than the lug and the space intermediate the lugs is just sufiicient to receive the inwardly extending foot 47, for a purpose which will be hereinafter more fully described. The arcuate plate 43 is held in its adjusted position by a spring clamp 48 which includes a pair of arms 49 having overlapping inwardly extending ears 50 which are pivotally mounted upon the reduced portion 51 of the upwardly extend ing stud 52, which is provided with an at taching plate 52 which is secured in posi tion on the upper end of the cabinet of the phonograph by suitable screws 54. The in ner terminals of the arms 49 carry suit-able friction pads 55 which are adapted to en gage the opposite faces of the plate The inner terminals of the arms 49 are normally held in engagement with the opposite faces of the plate by acoil spring 56, which is coiled around the reduced portion 51 of the stud 52, and has the opposite ends thereof engaging the inner faces of the arms.

The lever 22 in. rear of the depending arm 29 is provided with a. pair of spaced upwardly extending cut-out portions: or notches 57 and 58 and the notch 57 has the rear wall thereof provided with the inwardly extending foot 47, which. .is adapted to ride over the top surface of the lug 46 when the tone arm is moving over the record and is adapted to engage under the lug 46 when the tone arm: is being moved back to its original starting place. The notch. 58 is provided with an inwardly extending foot 59, which is formed on the rear wall thereof and the foot is adapted to ride. over the upper surface of the rearwardly extending lug 30, formed on the adjusting plate 61 when the tone arm is moved over the record in playing position and adapted to engage the under surface of the lug when the tone arm is being moved back to its original playing position. The adjusting plate 61 includes an angular extending base 62, which is slidably mounted on the upper surface of a relatively small plate 63, which is riveted or otherwise secured as at at to the upper surface of the base plate ll in rear of the arouate adjusting plate 43. The relatively small plate 63 covers a slot 65 formed 2 the plates ll, and the plate 63 is provided with a relatively small longitudinally extending slot 66, through which the rivet 67 slidably extends. This arrangement forms means for slidably mounting the plate 61 on the upper surface of the base plate a1 for a purpose which .will be hereinafter more fully described. The plate 61 is adjusted longitudinally of the base plate 41 by means of a screw 68, which is threaded into a nut 69 carried by the plate 61. The screw 68 is rotatably mounted upon an upstanding lug 70 formed on the upper surface of the base plate and is provided with an operating head or thumb piece 71. Movement of the screw in relation to the lug 70 is prevented by the collars 7 2 formed on or carried by the screw which engage the outer faces of the lug. It can be seen by turning the screw, the plate 61 will be moved toward or away from the lug 16, for a purpose which will be hereinafter more fully described.

Mounted on the base plate 41 intermediate the plate 13 and the plate 60 is an arcuate leaf spring 73, which has one terminal there of provided with an attaching foot 74, which is riveted or otherwise secured as at to the upper surface of the base plate 41. The leaf spring 73 extends from the end of the base plate 41 adjacent to the clamp 48 toward the lug 70 and has its free end provided with the upwardly and forwardly extending portion 7 6, which lies in plane above the main body portion 77. The lower face of the spring 7 3 is adapted to be engaged by the inwardly extendin foot 78 of the arm 79, formed on the lower surface of the lever 22 intermediate the notches 57 and 58.

Tn the operation of the improved device the tone arm B is moved toward the center of the record and the stylus carried by the reproducer D is placed in the last sound groove after which the clamp 48 is operated so as to release the plate 43, which is moved, so as to position the space intermediate the lugs 45 and 46 in direct alignment with the foot 4L7. Thus when a record is through playing, the foot 4:7 will be directly over the opening between the lugs as and 46. After this initial adjustment the reproducer is then n'iorcd over to the first sound groove and the machine is started in the ordinary manner. l Jhen the tone arm is being moved over the record the foot 4'? rides over the upper surface of the lug 46 and thefoot 59 rides over the upper surface of the lug 60, while the foot 7 8 of the arm 79 engages the under surface of the spring 73, and when the foot 7 8 engages the. curved portion of the spring and rides under the main portion '2'? of the spring and the end of the record is reached, he pressure of the spring will force the foot 4 into the declivity between the lugs 45 and 46, thus rocking the lever 22 on its pivot 23, which will raise the section 16 of the tone arm B on its pivot 17 and the stylus of the reproducer C out of the last sound groove and above the surface of the record and dispose the spring fingers 30 of the arm 29 in the path of the pins 31 and 32. Vlhen the pins 31 and 32 engage the spring fingers 30, the same will move the tone arm back over the top surface of the record and drop the stylus in the outer sound groove. The plate 43 is adjustable so that the repeating attachment can be used on records of a different length as all selections do not end at same point on the record tablet.

The plate 61 is also formed adjustable, so that in case records are provided with a larger outer margin than other records the same can be accounted for, although it has been found that records of one make all start from practically the same point. Thus it can be seen that when the foot 47 rides from under the lug t6, the foot- 59 will engage under the lug 60 and when the foot 59 rides from under the lug 60, the reproducer will be dropped.

To reduce the force of the drop of the stylus on the record, a leaf spring 80 is cured at one end as at 81 adjacent each of the pins 31 and 32 and the pin 31 is adapted to catch the outer spring finger 30 and move the same under the spring 80 which gently lowers the needle on the record.

The plate 61 and lug 60 is only adapted for use in playing ten inch records and when the twelve inch records are to be played, the attachment 82 is moved into position.

The attachment 82 includes the angular arm 83 which is mounted upon a post 84, rotatably mounted in a sleeve 85, which is provided with a base 86 which is riveted or otherwise secured as at 87 to the base plate 41 adjacent to the outer end thereof. The sleeve is provided with a slot 88 in which is slidably mounted the lug 89 which limits the swinging movement of the post. The inner end of the angular arm 83 is provided with a notch 90 at its inner face, and this notch forms means for permitting the foot 59 to ride out of engagement with the arm 83 when the end of the twelve inch record is reached. It can be seen that when a twelve inch record is placed, the post is turned so as to bring the inner end of the angular arm 83 in alignment with the lug 60 and the foot 59 will ride out or engagement withthe lug 60 into engagement with the lower surface of the arm 83 until the notch 9-0 is reached. The upper end of the post is provided with a thumb piece 91, by means of which the same may be readily turned. The post 8% has also mounted thereon an outwardly extending arm 92, provided with a flat head 93 which may be swung into the path of the tone arm it so desired for limiting the movement thereof to prevent the same from being swung cit of the record. An expansion spring 94- is coiled around the post 84: intermediate the angle arm 83 and the upper surface of the sleeve 85 and this spring is carried by the post and exerts a pressure on the upper surface oi the sleeve so as to form a frictional lock for the post and prevent accidental turning movement in the sleeve orbearing 85.

From the foregoing description, it, can be seen that an improved attachment is provided for phonographs which will permit the repeating of the selection without any atten tion of the operator after the repeating attachment has been once set.

V The pins 31 and 32 are Spaced a sufiicient distance apart so as to permit the riding of the spring fingers 30 therebetween. The pins 31 are adapted to move the tone arm when ten inch records are being played and the spring fingers are adapted to ride above the pin 32 when the end of the record is reached. \lVhen the angle arm 83 is swung in position so as to hold the spring fingers SO'in-their lowered position for playing twelve inch records, the pin 32 is adapted to engage the spring fingers 30 after the pins 31 and swing the tone arm to the first sound groove of the record.
