FIBER-NEEDLE SHARPENER FOR TALKING-MACHINE RECORDS.
Application filed June 3,
To all whom it may concern:
Be it known that JOHN QUEEN SLYE, a citizen of the United States of America, re-
siding at Washington, in the District of 5 Columbia, has invented new and useful Fiber-Needle Sharpeners for Talking-Machine Records, of which the following is a specification.
' As a rule wooden needles ,are used principally in connection with the best records,
- namely those which are rendered by the best singers and players, for instance, such as operatic music and the best songs in general.
A great many needles of this character are used and it is also known that when a fiber needle has been once used it is discarded. Possibly a needle may be used twice. And due to the fact that such needles are discarded after having been used once or twice,
0 a reat'many needles are used.
eretofore, as disclosed in the co-pending a plicationof John Queen Slye filed on the 2 th day of May, 1922, Serial No. 564,161, a suitable sharpening device has ben employed to sharpen fiber needles. The device as embodied in said application is supported detachably from the table of the talking machine. There are objections more or less to this character of sharpening device, due to 39 the attachable and detachable connections between it and the table. The ring in this" application and which constitutes the sharpener is mounted concentric with the table and has means to switch the needle from the track or groove on the ring to t the 'recor which may be supported upon the table. I 4
The present device has for its purpose the provision of a shar ener, either forming an 40 integral part of t e record, or separable therefrom and has an eccentrically disposed track connecting the sharpening track and the sound wave or groove of the record, so that as the fiber needle tracks around the sharpening groove or track it will automatically transfer or switch from the sharpening track to the sound groove.
Another purpose is to provide a sharpener of this character capable of being subse- 0 quently -applied to al records, or, as previously stated, being made an integral part of the records to be'molded.
/ It is to be understood that the particulars herein given are in no way h'mitiveand 1922. Serial No. 565,758.
while still keeping within the scope of the invention, any desired modification of detail and desired proportions maybe made in the apparatus according to circum-' stances.
Fig. 2 is a sectional view through the record on line 22 of Fig. 1, also showing a blank sheet of some suitable material to cover the sound groove while emery is being applied to the sharpening track.
Fig. 3 is an enlarged detail sectional view of a portion of a record, showing the sharpening track.
Fig. 4.- is still another enlarged view of a-portion of a record, showing a. ring pro- 'vided with a sharpening track and connected to the marginal edge of a record.
Fig. 5 is a plan view of a record, showing a ring applied to the marginal edge thereof, said ring having a spiral sharpening track.
Fig. 6 is asectional view on line 66 of Fig. 5.
Fig. 7 is an enlarged sectional view of a portion of the record shown in Fig. 6 showing the ring with its sharpening track on an en arged scale .as applied.
Referring to the drawings, 1 designates conventional form of talking machine record which is provided with the usual sound wave groove 2. This record is designed to be made of the usual material from which records are made, and during the course of construction the face of the record, near its marginal edge3, is supplied with a spiral sharpening groove 4, considerably deeper than the sound wave groove. In fact the sharpening groove or track 4 in actual practice is designed to be as dee as the beveled end 5 of a fiber needle 6 s own clearly in Fig. 3. The beveled end of such a needle is approximately of an inch, more or less, and by cutting down the surface of the bevel 5, the needle will become sharpened. Fiber needles are as a rule trian lar m cross section, and by providing a evel on one end, one corner of the needle is formed with the sharpening point which rides in the sound wave groove of the record.
The sharpening track or groove, approximately at a point indicated by the character 7, is connected by an eccentrically arranged track 8 with the sound, wave groove at a point indicated by the character 9. Ohviously, after once playing a record, and it is desired to repeat the record without changing the needle, the tone arm of a talking machine, not shown, may be shifted to the outer portion of the record so that the beveled face 5 of the fiber needle may engage the sharpening track 4. The sha 1}- ing track is approximately V-shape in cross section and it will be noted, as shown in Figs. 3 and 4, one wall 10 of the track 4- is relatively steep, while the opposite wall slopes on an angle approximately 45. This.
latter more or less gradual sloping wall 11 when formed is roughened, in order that a very fine layer of emery or carborundum or similar finely granulated material may be applied thereon, as indicated at 12. After -roughening the gradual sloping face 11, it
is first supp-lied with a' fine coating of adhesive material thinly distributed. Priorto applying this thin coat of adhesive material, the face of the record, which is provided with the sound wave groove, is first covered with a thin blank of suitable material, either paper, fabric or the like, such as indicated at 13 in Fig. 2. A suitable weight may be applied upon the blank to hold it flat against the face of the record, while the sharpening track or groove is being supplied with the adhesive material or the emery or carborundum. i
As previously stated the thin'layer of adhesive is applied while the sound wave groove is covered and subsequently to this the emery or carborundum, in the finely granulated or powdered form, is sprinkled or blown into ,the groove. After the adhesive has partly dried, the surplus emery or carborundum is blown or wiped from the margin of the record.
This action may be repeated two or three times before the adhesive becomes thoroughly dried and then after the adhesive is completely dry, a tool provided with suitable felt may be drawn through the track to insure wiping away the surplus emery or carborundum from the relatively steep wall of .the groove and at the same time remove parpoint. This hard-pointed toolis used sub: sequently to the use pointed tool. I
In Fig. 5 the talking machinerecord is the same as that shown in Fig. 1, but instead of the sharpenin track bein formed in a part of the recor it is formed on a ring 14,
of the felt covered which is subsequently applied to the record.
"upper portion of the rounded edge of the record, thereby acting to support the ring on the record, while the record may be supported upon the table.
The sharpening track in the ring 14 is formed in the same manner as the sharpening track carried by the record in Fig. 1. As shown in Fig. 5, the sharpening track,
from a point indicated at 18, merges into an eccentric portion 19, which terminates ad acent the inner edge of the ring. The sound wave groove 20 on the record, in Fig. 5, has an eccentric extension 21, which is designed to gradually increase in size toward "the marginal edge of the record to a point as indicated at 22 where it may join the eccentric extension 19 of the sharpening track of the ring. Obviously, when repeating the record shown in Fig. 5, the fiber needle is placed in engagement with the beginning of the sharpening track, and when it reaches the point or location 18, the needle automatically travels to the eccentric extension 19 (which merges into the eccentric extension 21), and then travels to the eccentric extens1on 21. As previously stated this latter extension gradually increases in size, that is to say, in cross section to a point where it merges into the eccentric extension 19, therefore when the fiber needle travels to the extension 21, it gradually merges into the sound wave groove 20.
In Fig. 4 a needle sharpening ring is shown as applied to the marginaledge of a record 23. This record is provided with a sharpening track similar to those illustrated in the other figures, but this ring 24 is ap plied to the record subsequently to the construction. of the record. This is accom plished by providing registering recesses 25 and 26 in the adjacent edge portions of the record and the ring, in which suitable metal plates or fasteners 27 may be embedded to hold the ring and the record rigidly connected, so as to rotate with the record as one body. These fasteners or plates are to be located so that the eccentric extensions 19 and 21 will register when the ring is applied to the record.
A sharpening track or groove of this char acter will remove orshave down just sufficient of the beveled end of a'fiber needle, to sharpen the point or corner of the needle, sufficiently to properly track in the sound wave groove of the record, in order to reproduce the record in the same manner as if reproduced by an entirely new needle.
hat is claimed is:
1. A talking machine record provided with a needle sharpening spiral track and an eccentric continuation of said track leading into and connecting with the record groove.
2. A talking machine record provided with a needle sharpening spiral track connected with the sound wave groove of the record, whereby the needle to be sharpened may automatically transfer from the sharpening track to the sound wave groove.
3. A talking machine record including a sound wave groove and provided with a spiral needle sharpening track adjacent the marginal edge of the record, and an eccentric connecting track connecting the spiral sharpening track and the sound wave groove, whereby the needle to. be sharpened automatically transfers from the sharpening track to the sound wave groove.
4. A talking machine record having a sound wave groove, the upper face of the record adjacent its marginal edge provided with a spiral sharpening track of a length sufiicient to impart a sharpening action to the stylus as the record makes at least one complete revolution, an eccentric groove tapering from the sharpening track to the sound wave groove and thereby connecting the sharpening track and the sound wave groove, whereby a needle may automatically transfer from one to the other.
5. A talking machine record having a sound wave groove, a ring separably mounted on the margin of the record and provided with a needle sharpening track, a needle transfer groove connecting the needle sharpening track and the sound wave groove of the record, to permit the needle to automatically transfer from one to the other.
6. A talking machine record provided with a sound wave groove, of a ring carried by the marginal edge of the record and provided upon its upper surface with a needle sharpening track, an eccentric track connecting the sharpening track and the sound wave groove whereby the needle may automatically transfer from one to the other.
-7. A talking machine record provided with a sound wave groove, a ring provided with an under-cut inner edge and provided with an overhanging lip to overlie the edge of the record and support the ring in position, said ring having a needle sharpening applying finely powdered emery or carborundum on the adhesive covered wall of the track, cutting down the emery covered wall, then subsequently cleaning off the surplus emery or carborundum.
9. A talking machine record provided with a sound wave groove, the upper face of the record between its marginal edge and the outer convolution of the sound wave "groove having a sharpening track extending spirallyfrom a point immediately adjacent the marginal ed e of the record to the sound wave groove, w ereby as a needle is sharpened, the record may travel at least a complete revolution, said spirally constructed sharpening track havin an abrupt spiral portion connecting wit the sound wave groove.
10. The combination with a talking machine record provided with a marginal beveled edge extending slightly downwardly I and outwardly, of a ring with its inner edge under-beveled to correspond to and engage with the beveled margin of the record for separably supporting the ring on the record, said ring having a grinding track for sharpening a needle, said sharpening track having a transfer groove abruptly spiral and connecting with the sharpening groove and the sound wave groove to ermit the needle to automatically transfer om one to the other.
11. A method-of constructing the sharpening track of a talking machine record,
which first consists in cutting a track on the upper face of the record between the sound wave roove and the margin of the record, spiral y toward and connecting to the sound Wave groove, covering the sound wave groove to expose the surface having the sharpening track, adhesively ap lying finely powdered emery or carborun um 1n the track and cuttin down the emery covered walls of the trac and subsequently cleaning off the surplus emery or carborundum.
In witness whereof, the inventors signature is hereunto aflixed.
