' Louis DEVINEAU, or CLEVELAND, OHIO PHONO GRAPH.

To all whom it may concern: Be it known that 1, Louis Dnvmnao, a citizen of the United States, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented a certain new and useful Improvement in Phonographs, of which thefollow' g is a full, clear, and exact description, reference beinghad to the accompanying drawings.

The object of thii invention is to provide mechanism whereby either disk or cylinder records may be used on the same phonograph.

' More particularly the invention comprises an attachmm for a cylinder phonograph arranged to properly rotate disk records. I

The invention, including this and other features, is hereinafter more fully described and the essential characteristics set out in the claims.

Figure 1 is an end view of a phonograph with my arrangement and with a suitably supported horn; Fig. 2 is a perspectiveof the driving ring; Fig. 3 is a perspective view of my dislerotating mechanism detached; Fig. t is enlarged side view of the supporting pipe for the reproducer.andhorn; Fig. 5 is a section showing a valve in suchpipe; Fig. 6 is a section showing a ball joint in the pipe; Fig. 7 'is a vertical section through the diskin each figure. 1

Referring to the parts by numerals: lrepresents the. box-like base of an ordinary cylinder phonograph on whichis mounted the rotatable mandrel 2, supported .at its free end by the hinged gate3, and adapted to carry the ordinary cylinder record My mechanism is supported by'a standard 4, which has a flange 5, extending under the box 1, and an arm 6, which carries a thumb screw 7, bearing down on the top of the box. This holds the standard firmly in place. v V

Slidingly carried on the standard is a rod 9, at the upper end-of which is a head 10. Clamped on this head by thumb nut 11, is a plate 12, which carries a sleeve 15. Journaled within this sleeve is a shaft 16, thefupper end of which carries a disl ]7, adapted to gupport the record 18, while the lower end carries a disk 19,- adapted to engage a rubber tire 20, on a ring 21, surrounding the mandrel and ,fitting tight thereon. Ijiy thi s'means the disk'record 18, is rotated by the mechanism whichordinarily-rotates the cylinder record on the mandrel 2. .The mandrel is driven by any suitable mechanism within the box as indicated by dotted lines in Fig. 1, where 22 represents a motor, from which runs a belt 23, onto a pulley 24, on the shaft of the mandrel.

There are various refinements and adjustments in the parts referred to which I will now describe. The rod 9, is clamped to the standard 1, by a set scrc w 25, which allows vertical adjustment as well as swinging onthe Specification ofL-stters Patent.

rod as an axis. The clamping nut 11, screws onto the upper end of the rod 9, which extends through a slot 26, in the 'plate 12, wherefore this plate may be adjusted in and out. By this means the disk 19, maybe located as desired over the driving ring 20, the speed, of rotation of the disk being governed by the distance between its center and the point of engagement of the ring 20.

The plate 12, is bent near its end into substantially a U-shapo as shown at 27, and the sleeve 15 has a serew thread on its outer side which screws through said openings in the two portions of the plate 12. This lurnishes means for adjusting the sleeve up and down. Moreover a screw, 29 engaging the two portions of the plate 12, is adapted to move the free end toward or from the intermediate portion of the plate, thus causing the thread to bind and taking the place of a jam nut.

The shaft 16, is journaled within the sleeve 15, on a ball bearing provided by a cup 25], formed at the lower end of the shaft, and a nut 32, screw threaded on the shaft above the sleeve. Sets of balls 33 and 34', roll between the cup 31, and the lower end of the sleeve 15, and between the upper end of the sleeve and the nut 32 respectively. The nut 32, is jammed by having a portion 36, which is separated by a kerf from the rest oi the nut and may be sprung bya nut 38, screwing through the portion 36, into the body of the nut. The disk 17, which supports the record has a hub 39, in the lower face of which is a recess to receive the head of the screw 38, thus compelling the disk to rotate with the shaft. A piece of felt or other suitable material 40, is secured to the upper face of the disk 17 and the record 18 rests thereon and is driven by friction.

In order to obtain the proper friction between-the driving ring 20, and the disk 19, I give that disk a spring action by making it of thin metal and cutting out sectonshapcd openings 42, to leave a series of spokes 43, carrying the disk. This allows the disk to bear on the ring with sufiicient friction, the barrel 15, being screwed downwardly sufficiently to cause the disk 19, to bebent upward slightly on the side engaging the ring 20. The disk 19, is secured by a screw ing anything accidentally passing between the driving members or dropping into the openings 42.

The reproducing mechanism which cooperates with the disk is also carried by the plate 12, At. its'outer end this plate has annpturned portion 50, which is then turned horizontally and downward as at 5]. A

a ,vcrlical shaft car 55, the outer ends of which are connected by screws with lugs on the tube 56, which is formed as an elbow, as shown. 57, which is a segment of a sphere, and in this segment is pivoted the partially spherical end 58 of the neck 59 of the sound box. The sound box has a cylindrical extension (50, from this neck which carries th diaphragm 61, with which cooperates the repr ucing needle 62. By reason of the pivot between the heads 57 and 58, this reproducing needle can play up and down, while the journaling of the rod 53 in the tube 52 allows the reproducer to swing laterally under the influence of the spiral groove on the record disk.

On the upper end of the elbow 5G is formed a partially spherical recess (55, in which seats the lower partially spherical head (36 of an upper elbow 67. This head is freely held in place by the nut 68, but is allowed movement to make an easy connection between the horn and the elbow 56. The horn, designated 70, is supported in any suitable manner, as indicated by the stand 7i, which is selected as illustrative. On the inner end oi the horn is a rubber section 73, which connects the born with the upper end oi the elbow 67.

To regulate the degree of sound, 1 provide a valve in the passageway from the sound box to the born. This valve, as shown in the drawing consists of a plug 75, seating in the elbow 67. and carrying a knurled head 76, by which it may be turned, there being a large cylindrical passageway through the plug so that it may leave the bore of the elbow (37, unobstructed. or reduce it as desired. The friction of the plug with the walls of the tube is suliicient to hold the'plug in place.

To produce propersound it is necessary not only that the disk be rotated and lhe reproducer supported in engagement therewith, but that. such rotation be ea y, and without jerk or irregularity. The reproducer needle must rest lightly and easily thereon and there mu be no scratching or scraping oi any kind. These results are obtained byihe various adjustments and relinemcnts in mymechanism as above explained. Moreover my adjustments allow my mechanism to be attached to cylindrical phonographs of various sizes. There are a largo number of such phonograpbs in existence and frequently it. is desired to reproduce a record which does not exist in the cylinder l'orni but does in the disk iorln. i\l v mechanism enables the disk records to be operated by llic cylinder phonograph whenever desired. .\l the same time it may be instantly removed to allow cylinder records to be used.

Having thus described my invention. 1 claim:-
