Specification of- Letters Patent.
Patented Nov. 16, 1915.
Application filed May 25, 1914. Serial No. 840,653.
To all whom it may'conce m.
Be it known that I, GEORGE C. WHITE, a
citizen of the United States, residing at Baltimore, in the State of -Maryland, have invented certain. new and useful Improvements in Reproducer-Supports for Graphophones, of which the following is a specification.
This invention relates to an improved means for sustaining reproducers of graphophones.
an improved means for sustaining reproducers so as to enable the same to have a record disks are employed and commercially freedom of movement not heretofore permitted and to also provide a reproducer support that will enable the reproducer'to have a playing position substantially tangential with respect to the grooves in the record disk, or substantially crosswise of the said diskgrooves. I a j At the present time two distinct forms'of.
known as Victor or Columbia records and Edison records. In the case of the Victor and Columbia records the side wall of the record disk groove is provided with irregu larities with which the reproducer needle-.co-J.
acts so as to reproduce the sound. In the grooves as above noted are necessary.
case of the Edison records the grooves of the disk are provided with irregularities in the bottom of the groove. In the Victor and -Columbia disks the grooves of which have an irregular side wall, the reprochlcerin practice is sustained vertically so-that-fit diaphragm will have position substantialll tangential with. respect to the grooves whereas int-he case of the Edison-disks with the grooves of irregular bottom, the'reprdducer in practice is sustained ina horizontal position. The respective positions'of the reproducers with respect to the two forms of My invention therefore has; for its obj to provide a reproducer support of such cone struction that the reproducer may be carried so as to operate with disk-records of either of the types referred to.
With these and other objects in view, the invention is illustrated in the accompanying N drawing, wherein,-
Figure 1, shows in top plan, a coiiventional reproducer arm of the V1'ctor.type to.
which my improved device is attached,-- the reproducer being in sosition to operate With either a Victor .or
The object of the invention is to provide l1ne8-8ko m g. t I .fkligiglllllgftii) the drawing the numeral 9,
iiproved' attachment mainly comprises two lbowfmembers 14-and 15 respectively which ect olumbiadisk record. Fig.2, illustrates a side elevation of the improved attachment with the reproducer detached. Fig. 3, shows a rear elevation of the same. Fig. 4:, illustrates a crosssectional detail on the line of Fig. 3. Fig. 5, shows a top plan of the--attachment carrying the .reproducer and 'inpositi'onto I cooperate with a disk record of the Edison type. Fig. 6, shows the same in side elev'a reproducer :is to be attached-,,and Fig. 8, shows a verticallsectional detail through the.
attachment, ;-the section being taken on the designates. a tubular armwhich in practiceis 'usually pivoted at 10, so its outer smaller 75 end may swing horizontally over the record disk. In the present instance the onter --sma1ler end of this arm is providedwith a sleeve 11, which pivotally sustains a tubular coupling 12, as is well known in the Victor the reproducer 13, is usually-attached to the forward end of the coupling while in the Columbia machine the attachment of the re producer is}made direct1y to the small end of the arm 9,,but1i'n'either case m'yimproved device will be I-at'tachedand interposed between the saidgreproducer and the said arm.
By referring particularly to Figs. 2 and 3 ofthe -drawing,it'will be noted that the imre telescopicallyengaged at'16, softhat the upper elbow member l5,"ma,y berotated or swung with respect tothe lowerelbow mem -.ber'-14=.L:-.The up-turned end of the lower elbow member 14, is provided with a circumfenential segment slot :17, and the down vided withya stop'screw 1 8; which passes pling-'12,'in -eea se of a Victor machine ordirectly to the 'arm 9, ofa Coll lmbia -inachine. In the present instance 'a 'bin din'g screw. .20, is provided on'the coupling collar 19, to .etfect a rigid attachment to thatpa'rtyl'lo which, it engages. 4
The upper elbow member 15, carries a c5 tion with thereproducer removed. Fig; 7, 7 .1llustrates-in-side elevation adetailjoffthe. universal ball part of the .jointon whichPthe machine. In practice in'the-Victor-machine semi-circular socket member 21, which has an adjusting screw 22, at its upper side and said socket is also provided with side perforations 23, in its directly opposite sides and in line with its horizontal axis. A ball member 24 snugly fits said socket 21, and carries two horizontally-projecting pins 25,one in each side, that extend outwardly therefrom and pass freely through the side perforations 23, in the socket member so as to have a freedom of movement in said perforations. The outer side of the ball member is provided with a circular band portion 26, with a bayonet slot 27, in its edge whereby it may readily receive the reproducer 13, in the usual way. A spring finger 28, is secured inside of the circular band of the ball member and projects rearwardly so as to engage a shoulder 29, in the socket member,said spring serving to yieldingly act on the band portion of the ball member when the reproducer is attached thereto and thus the pressure of the needle against the wall of the disk groovesis a yielding pressure that will permit the reproducer to yield in a direction at right angles to the movement allowed between the sleeve 11 and coupling 12. The upper curved surface of the ball member is provided. with a groove, into which the screw 22, projects from the socket member, as clearly shown in Figs. 4 and 8 of the drawing, said screw being loose in the groove so as to permit a limited movement of the ball in the socket.
In the operation of the device the attachment may be readily connected to the arm 9, or to the coupling 12, at the point where the reproducers have heretofore been attached, while the reproducer will be connected to the band 26, of the ball member 24.
When it is desired to use the reproducer in connection with a Victor or Columbia disk record in which the side wall of the record grooves is provided with the irregularities, the upper elbow member 15, will be swung on the lower elbow 14, so that the flat face side 31, of the reproducer 13, will have position in a vertical plane substantially parallel with the longitudinal axis of the arm 9. When the reproducer is in this position its face- 31, will have a position in a plane that is substantially tangential with respect to the record disk grooves, as indicated by the broken curved lines 32, in Fig. 1, of the drawing, and in this position the matter, of which the disk is a record, will be reproduced. When it is desired to use the reproducer in connection with an Edison record in which latter the irregular wall of the groove is at the bottom, the upper elbow 15, will be swung on the lower elbow to ,the position shown in Figs 5 and 6 of the drawing in which the fiat outer face 31, of the reproducer will have position in a vertical plane substantially at right angles to longi tudinal axis of arm 9, and cross-wise of the grooves of the record disk as indicated by broken lines 33, in Fig. 5 of the drawing. It will thus be seen that by simply shifting the one reproducer from a position where its face will be substantially on a tangent with respect to the record disk grooves to a position where such face will extend crosswise of said grooves, either a record of the Victor type or a record of the Edison type may be played.
Having described my invention what I desire to secure by Letters Patent is 1. In a reproducer support fo grapliophones the combination with an elbow memher having means to connect it with a swinging graphophone arm, of a second elbow member having one end rotatably connected with the first named elbow member said sec-- ond elbow member having a ball and socket connection and said connection having means for engaging a reproducer.
2. In a reproducer support for graphophones the combination with a reproducer, of a ball member of a ball and socket joint, connected to said reproducer; a socket member of said ball and socket joint, to receive said ball member; an elbow member carrying said socket member and a second elbow member rotatably connected to said firstnamed elbow member said second elbow member having means to connect it with a graphophone arm.
3. In a reproducer support for graphophones the combination with two elbow members rotatably connected and having means to limit'the rotating movement, of a ball and socket connection carried by one of said elbow members; yielding means in the interior of said connection and means for connecting the ball and socket connections to a reproducer.
4. In a reproducer support for graphophones the combination with a reproducer, of a ball member connected to said reproducer said ball member having a groove in one side and pivot pins at diametrically opposite sides; an elbow having a socket member to receive said ball said socket member provided with a pin to enter the ball-groove and also having perforations to receive the pivot pins on the ball member; a swinging arm, and means for rotatably connecting the elbow with respect to the swinging arm.
In testimony whereof I affix my signature in presence of two witnesses.
GEORGE C. WHITE.
