To all w/romtmay concern.
' Be it known that I', SAMUEL Levin, a citiA zenof the United States, residing at High'- land Par-k, in the county of Lake and State' of Illinois, Stylus, cation.
The present invention relates to an im` of which the following is 'a specifi- `proved stylus, especially ada; ted-to be used in connection with disk sound reproducing machines, one object of the invention, bef
ing the provision` of a-stylus, Which being made of resilient material, which is rectangular in cross section, will notunduly scratch .the sound grooves of the'record and which will be provided with a plurality of groove engaging points, so thatthe life of the stylus Will be greatly increased, as will metal, liber,
also the life ofthe record.
A further object of the invention is the provision of a flat resilientstylus, which maybe composed of any material, either wood, Celluloid or in fact any material that will answer the purpose, the opposite ends of the samev being provided elthervwith a plurality ofgroove engaging points or asingle groove engaging point, so that the same may be readily attached to the usual form of reproducer .used in connection with disk sound reproducing machines, the same being Adisposed at an angle to the sound groove, and the rotation thereof, so as to resilientlyv support the sound reproducer and thus reduce the wear upon the record, such stylus when having more than one point upon each end, being disposed at such angle, that only one point is in engagement with the -sound gecerd groove, While the other point is elevated thereabove.
With the foregoing and other objects inA view' which will appear as the description proceeds, the invention resides in the combination and arrangement of parts andin the details of construction hereinafter described and claimed, it being understoodI that 'changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit ofthe invention.
In the drawings Figure 1 is a plan View of one form of stylus made according to and embodying the present invention. Figs. 2, 3, and 4 are plan views of modified forms of stylus embodying the present in vention. Fig. 5 is a diagrammatic view of a have m'ventcd a new and vuseful thus held out reproducer, and a portion of a disk record with the stylus as shown in Fig. 1 in operable relation thereto. Fig. 6 is a bottom planl view ofthe stylus receiving member of the reproducer showing the position the stylus is held in when clamped thereto.
Referring to the drawings, and particularly to Figs. l, 5 and 6 thereof, the stylus l'is composed of a flatstrip of material, rectangular in cross-section, and has its ends cut or grooved so as to provide thefourv record groove engaging points 2, 3, 4 and `5. It vwill thus be seen that this stylus Ais provided with two record upon each end thereof, and is readily insertible within the ,triangular stylus receiving socket 7 of the stylus clamping member 8, so that the stylus 1 when in proper clamping position will rest against one inclined wall 6 and. 4be held engaging points that such stylus` thereagainst, as shown in Fig. 6 by means of 11e-locking screw 9. It is therefore apparent that when the stylus is in the clamp, as'
clearly shown in Figs. 5 and 6, that one point as 3 will be placed in engagement with the groove of the disk D, While the point 2 upon the same end of the stylus due to the inclining of the reproducer R and the angle at which the body of the stylus'l is presented to the disk, will be elevated above the surface of the disk and of contact therewith. It is also evident that the body of the stylus is presented at an angle to the groove of the record D, so that a slight flexing of the body thereof is permitted, such flexing' forming a resilient support for the reproducer R, so that no undue. strain is placed upon the portion of a sound record engaged by the point ,2, such resilient action reducing the friction to prevent undue Wear at such point.
It is apparent that many forms of styli embodying the present invention may be provided, and as particularly shown in Fig. 2, the opposite ends of the stylus lOvarepro-` vided'with a curved recess 11--11a to vide four points asin the structure shown in Fig. 1. ,l
In-Fig. 3, the flat stylus 12 is provided with the parallel `cut ends 13 and 14, being at an angle to the body of the stylus, such cutting of the ends providing two points instead of four upon the stylus and thus providing a double Wear.
In'the form shown 'in Fig. 4, the stylus 15 has its opposite ends 16 and 17 cut so proas to present two record-engaging points at the same edge of the stylus, thus in another manner providing two points one upon each end of the body of the stylus.
in all of the forms herein illustrated, the stylus will be positioned and properly connected in the clamping member 8, as 'clearly shown in Figs, 5 and 6, so that the resilient action of the stylus due to the weight of the reproducen thereupon and the angle 'of' the presentation-'of the body of'the stylus to the record D, will prevent' any undue.
- thereof is disposed atl 'an acute angle tothepath of the sound grooves of a record, and
` whereby the reproducer is resiliently sup- .l ported by the stylus.
2. The combination with a reproducer having a stylus receiving clamp provided with a triangular socketwo a stylus composed of a fiat relatively thin strip ofresilient material disposed against one 'wall of the socket of the clamp so that the body thereof is disposed at an acute angle to the.
paf-.h of the sound grooves of the record, and whereby the reproducer is resiliently supported by the stylus, the opposite ends of said strip each being provided with a record engaging point.
3. The combination with a sound reproducerhaving a stylus receiving clamp pr'ovided with a triangular socket, of a stylus composed of a iat'relatively thin strip of resilient material disposed within the socket of the clamp, whereby the body of the stylus is held co-extensive with one Wall of the socket to be disposed at an acute angle to the path of the sound groove of the record and forms a resilient support for the reproducer,
l 4. The combination with a sound reproducer having a stylus receiving clamp provided' with a, triangular socket, of a stylus composed of a fiat relatively thin strip of resilient material mounted within the socket of the clamp, whereby the body of the stylus Ais held vco-extensive with one wall of the socket to be disposed at an acute angle to- `,ing means.
5. The combination with a sound repro;l
ducer having a stylus receiving clamp provided with'a triangular socket, of a stylus composed of a flat relatively thin strip of `resilient material mounted within the socket Aoi' the clamp, whereby the body of the stylus is held co-extensive with one wall of thel socket to be disposed atan acute angle t`o the path of the sound groove of a. record and forms a resilient support for the reproducer, the opposite ends of the stylus, eacn being provided with a plurality of points for engagement one at a time with the sound groove of a record. l
In testimony that claim the foregoing as my own, l have hereto aixed my signature in the presence of two witnesses.
