STYLUS FOR SOUND-REPBObUOING MACHINES.
Specification of Letters Patent.
Patented. June 16, 1908.
Application filed November 16, 1907. Serial No. 402,491.
To (ill whom it may concern:-
Be it known that I, SAMUEL LEVIN, a citizen of the United State s,'residing at Highland Park, in the county of Lake and State of Illinois, have invented a new and useful Stylus for Sound-Reproducing Machines, of WhlCll the following is a specification.
This invention has reference to im rovements in the reproducing point or sty us for sound-reproducm machines, and its' ob'ect is to providea sty us which will give a mel ow and soft-toned re roduction, more particularly from flat or dlsk-shaped records wherein groove of even depth. The }present invention is an improvement e invention disclosed in my applicat1on #361,122, for stylus for sound-reproduc mg machines filed March 7, 1907. In the sald application, the stylus is made of a thin as 11111, with one endent into a cylinder of a size to fit the stylus holdin socket of a sound box, while .t e other en is fiat, thin and tapering and is adapted to engage 1n the sound record groove.
The resent invention utilizes the same materia for the record groove engaging closely embracing the quill an point, while the body or shank of the stylus is made of metal or other ri 'd material comparatively close to the operating point thereof. This metallic shank is made 0 lindrical through the eater ortion 0 its len th to fit the soc et in t e end of the sty us lever and at the free end the shank is flattened to conform to the flattened end of the working point of the stylus, and also to operate to transmit the vibrations imparted to the. stylus point with lessloss of amplitude than occurs with an all-quill st lus.
The invention will be best un erstood from the following detail description, taken in larged scale, of a forming part of this spec drawing,
connection with the accompanying drawln catlon, in who is'a longitudinal section of the stylus' upon a still larger scale.
' as to enter t horny, homo eneous material, such of the stylus carrying extending ox with the improved Referring to the drawings, there is shown-a sound box 1 which may be of any desired construction such as is used in connection with sound-reproducing machines using flat disk records, and no special description of suchsound box is necessary, since, in itself, it forms no art of the present invention.
.The sty us is formed of two parts, 2, 3. The part 2 is com osed of a piece of horny, homogeneous, har material, such as a tlnn piece of horn, or goose quill, celluloid, or some such substance. One end of the part 2 is spread out into a nearly fiat shape with the sides .4 approaching each other until they finally emer e into a point 5 of such size ie sound record groove of the well-known sound diskrecords. Back of the wide portion 6 of the stylus oint or head the quill may be continued a istance, as indicated at 7. The part 3 of the stylus, which may be termed t e shank of thestylus, is formed of a metallic tube of cylindrical shape of such external diameter as to fit snugly but easily into the usual jsltylus receiving socket ever of the sound box. This shank extends onto the part 2 as near to the o erating end 5 thereof as may be found pract cable. In the drawing, the metal tube 3 is shown as reaching to a point just back of the widest portion 6 of the part 2, but it is within the scope of the invention to extend the metal tube still closer to the working end 5.' In order that the tube 3 may grasp the part 2 closely about the fiat portlon thereof, that end of the tube conti uous to the working point of the part 2 is attened, as shown at 8, so as to graspthe workm point 2 both on the sides andends in order t at there may be no lost motion between the parts '2 and 3. The extent of projection of the part 7 into the tube 3 is immaterial and may be much less than that shown, as long as the parts 2 and 3 are firmly united and the part 2 is prevented from any movement in, or independent of, the part 3.
By making the part 3 of sufficient rigldity, and b allowing the part 2 to project but little eyond the outer end of the part 3, there is produced a stylus having a rigid, unyielding shank with an operatmg oint or end for engaging the sound groove w ich Wlll have no'.wearing or other m]1111011S effects upon the walls of the groove, and therefore the life of the record tablets s mdefimtely prolonged. Furthermore, the harsh, grating noises, so obtrusive when all-metal stylus points are used, are practically eliminated.
The present invention retains all the advantages of the structure set forth in my aforesaid application, while addin thereto the additional advantage of a sti and unyielding shank for the stylus. The structure of the aforesaid a plication is well adapted for the so-called soft tone reproductions of sound records, but where louder. and more brilliant reproductions are desired, thestylus made entirely of quill or like material fails to produce the desired brilliancy and loudness of reproduction. This is due to the elasticity of the material used and the consequent absorption of a material proportion of the amplitude of vibration imparted by the roove to the stylus before the vibrations reac the stylus carrying lever. The metal sleeve, however, is much less elastic than the horny substance employed and, consequently, there is little, if'any, loss of amplitude of vibration between the sound record groove and the stylus carryin lever. The result is that the brilliancy andqoudness of the reproduced sound is practically equal to the reproduction through an all-metal stylus used for loud-toned reproductions, while the harsh, grating, extraneous noises are practically eliminated and the wear ofthe stylus upon 17%? walls of the rec ord groove is inapprecia e. I
I 'claim:
*1. A stylus for sound-reproducing machines composed-of a sound-groove-engaging portion consisting of a thin piece of orny, omogeneous material having one end approximately. flatwith the sides approaching and merging into a soundoove-engagin point, and a' shank compose of a cylinder 0 ing point 0 horny homogeneous-material and a shank portion of another material of more rigid character than the point portion. In testimony that Iclaim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
