LESLIE MCARTHUR, 0F KENILWORTI-I, ILLINOIS, ASSIGNOR TO STEWART PHONOGRAPH CORPORATION, OF CHICAGO, ILLINOIS, A. CORPORATION OF ILLINOIS.
PHONOGRAPH.
Specification of Letters Patent.
Patented Mar. 19,1918.
Original application ltiled November 24, 1916, Serial No. 133,139. Divided and this application led April 23,
1917. Serial No. 163,777.
To all whom it may concern:
Be it known that I, LESLIE MoAR'rHUR, a subject of the King of Great Britain, residing at Kenilworth, in the county of Cook and State of Illinois, have. invented new and useful Improvements in Phonographs, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.
'Ihis application is a division of my pending application, Serial No. 133,139, filed November 24, 1916.
The purpose of this invention is to provide an improved construction in certain details of a phonograph or talking machine, so-
called. It consists in the features and elev ments of construction shown and described, as indicated in the claims.
In the drawings:
Figure 1 is a detail side elevation of a por! v tion of a phonograph comprising the tone arm and sound box mounted thereon, the same being shown in relation to the record with which the stylus on the sound box cooperates.
Fig. 2 is a section at the line, 2-2, on Fig. 1.
Fig. 3 is a detail section at the line, 3 3, on Fig. 2.
Referring to the drawings z-The reproducer or sound box, A, carrying the stylus, B, is connected to the tone arm, E, by means of an elbow on the tone arm having an obliquely-extending arm, B1, which is intertelescoped with an obli uely-extending arm, C, of the elbow, C, rigid with the sound box. The inclined elbow arms, B1 and C1, are mounted upon each other for relative rotation about their common axis, constituting a swivel connection between the tone arm and the sound box about whose axis the sound box may be adjusted from a position at which the stylus, B, may coperate with a record, F, of the zig-Zag type, to a position at which it may coperate properly with a record of the hill-and-valley type. For the purpose of rendering this joint snug and adapted to cause the sound boX to remain safely at either position to which it is adapted, and at the same time rendering said adjustment reasonable easy, the intertelescoped parts at this joint,-said arms, B1 and C1,are provided with recesses b1 amount of the annular adjustment of the two members upon each other which is made for shifting the sound box from one of said operative positionsto the other; and the spring thereby, together with the recesses in which it is lodged, constitutes the means for limiting this adjusting movement of the sound box. This spring being a flat spring, and the recesses in which it is lodged being channels in the respective members whose width is substantially that of the flat spring, said spring when engaged in the channels of the two members constitutes a key for retaining the two members together. It is understood that the two members will be engaged with the key spring therein by first placing the spring in the recess in the inner member, its ends being lodged in said recess, and compressing the middle point or bow to admit it into the other of said members, B1, whereupon the two members being longitudinally telescoped to their stop shoulders, the recesses, b1, and c1, being thereby registered with each other, the bow of the spring will snap into the recess, b1, and the members will be locked together. That they cannot be disengaged is not an objection. In case of breakage of the spring, it will be preferable to substitute an entire new joint rather than to undertake repairs. It may be considered desirable to provide for the y Y vided for.
l. In a phonograph, in combination with a sound box, a tone arm, elbows on the sound box and tone arm respectively, and a tubular joint at which said elbows are connected, comprising inter-telesco ed arms of the elbow adapted for relative rotation about their common axis, having their inter-telescoped parts recessed, forming a cavity between them, and a bow spring lodged in said cavity, re-acting between said inter-telescoped parts for rictionally resisting their relative rotation. v
2. In a phonograph, in combination, a sound box tone arm, and a tubular joint at which the sound box and tone arm are connected, comprising inter-telesooped members adapted to rotate relatively about their common axis, said members having at their inter-telescoped portions recesses forming a cavity between them, and a spring lodged in said cavity, re-acting on both-said parts for frictionally resisting their relative rotation. In testimony whereof, I have hereunto set my hand at Chicago, Illinois, this 20th day of April, 1917.
LESLIE MCARTHUR. v
