"1' u; lhe (lreu'i: one Qlllbfillh ii'n'ention comprises a hollow lune arm or souiul box arm 1. luh slam l"'l of which "preferably prosubs; utiellv horizontally autl the of which is turned downwardly l ;h on are of (legrees and terminates l I suhstzuilinlly vertical cylindrical porlion iounectetl lo the smaller end of the tone arm 3 in any Well known or suitable manner so as to communicate therewith and he ""zihle ugmarclly e115. downwardly with souzul hox l offiinv 1 construction. l u ho 10 ctmueotetl f the tone illlfl iii'u ens of a longitu- 11b9 11, one end of which is iiectetl to the Smaller end at the 1e othe enal of u in axial rilinemeiit with the larger end 4 of the sound box arm, a downwardly eK- tending hollow bracket or support 15 which is fixed in position by being rigidly secured to the usual cabinet (hotshot-vii) of the talking; machine" or to any other fixed support. The upper end of the hollow bracket 15 is substantially cylindrical in shape and is enlarged externally as at 16 and provided internally with an annular cylindrical reu short distancedownwardly into the en:
tieul socket l7.
'l'elescoping in the socket 17 of the hollow support 15 is a substantially cylindrical and \ortieul hollow head or casing 20, the lower end of the head being reduced in diameter externally, or provided with an external :iunulur recess, to form a cylindrical neck 31 which fits snugli bul removably into the recess 17 of'the. bracket Between the neck 21 of the casing and the uuoer portion thereof. there is thus formed an annular external shoulder which rests upon the upper encl of the bra cket 16 when the casing is in operative position in the bracket. The casing '20 heltlin a fixed position in the bracket 15 by means of a thumb screw 23 threaded through the upper portion of the bracket and engaging against the neck 21 of the casing. and the casing may be reaclil} removed from the bracketwhen the screw is loosened.
The upper end of the casing 20 surrounds and is spaced from the lower or larger end 4- of the tone arm 1, and is closed l) V an annular cover in vmich the larger end 4- of the tone arm The under witl. an annular Q erred, lo the arm by anysuitable means, the
sleeve-preferably fitting tightly around the 21 Till The sleeve is preferably enlarged. at
l 1 each end anal is provided at each end with cess extending from the top of thebracket largecl end or the bracket forming a ver' friction bulls on.
Oil-will an uni'iular external groove coaxial therewith to form annular liccringzs 31 for antiballs 32 surrounding the upper end sleeve rest in. an annular room-:13 by the annular bcuring f-ll upon the cod of the slccvc and unnulur licorrorincd by the inner portion m the: upper end of the casing and the adjacent 1c portion f the cover 25, and the balls surrounding the low-c1 end of the sleeve rest in an annular raceway formed between tho annular hearing 31 on, the lower end of the sleeve 30 and thc corrcsponding annular hcorin g 33 formed in, the casing.
Prc'rorzzhly but three balls 32 are uscd in each annular rnccivuy l'ietvvccn the sleeve 30 and the casing thus forming a three point'suoport in each raceway for the tone arm, llho tbicc balls in each raceway arc prcfcrnhly coin-spaced, each bull being separiitcd from each. suljacent ball by means of a scginchf 'l space bar 35, pz'cl'crablv round in cross section, which fits loosely in the raccwoy.
From the foregoing description, it ovidon't that this invention provides a simple rind duriihlc anti-friction mounting for a tone arm by which the tone arm will be rc strained to rotate or oscillate lrecly about u axis By providing the larger and of tho tone arm with spaced annular hearings or ruccvvziys, each containing a set of three bolls, tho larger end of the lone arm is held against ltl-l'fiflll' or longitudinal movcnicnt and the smaller or tree (and? of the tone arm restrained to rotate or oscillate smoothly and freely in a horizontal plane about an coincident with tho longitudinul vertical axis of the largcr end of the tone arni. By thusinounting the tone arm, a maximum clliciency of the sound box is obtained.
Although only 8.- single form has been illustrated hcrcin in which this invention may be embodied, the invention isnot limited to any particular construction but may be varied to meet various conditions Without departing from the spirit of this invention or the scope of the appended claims.
Having thus described my invention, 1. claim and desire to protcct by Letters Pub out of tho United States:
