W. B. NICHOLS. NEEDLE FOR TALKING MACHINES, Szc.

APPLICATION FILED MAY 28- 1912.

Patented H0126, 1912.

WALTER n. NICHOLS, or nnxme rdm-xnnrucnm NEEDLE FOB TALIflNG-MAOHINES, 850.

and State of Kentucky haVe invented certain new and useful Improvements in Needles for Talking-Machines, &.c., of which the following is a specification.

This invention relates to improvements in needles for use in talking machines, and the object of the invention is to provide a needle which may be made of wood or fibrous material and at the same time have a number of needle points, thereby providing a multiple needle. I

In its preferred embodiment my invention has a plurality of individual points connect ed together by curved surfaces whereb a file or tool of the proper character may e employed to file or grind the curved surfaces so as to renew the needle points when worn.

In the drawings accompanying and formpart hereof: Figure 1 represents part of a talking machine having a needle made in accordance with m invention connected with the sound box t ereof. Fi 2 is a erspective view of the needle detac ed. 1 Fig. 3 is a view partly in section of my multiple needle in. a sound bom Fig. 4 is a view of a modified formQ Referring now to the details of the drawingsby numeralszl designates a sound box of ordinary construction to the socket,2 of which is secured the shank 3 of my multiple needle. The needle itself is designated by the numerals and in its preferable embodi- ,ment consists of a solid.piece of box-wood,- although other characters of wood ma. be emplo ed. The shank 3 is of the size a apted to fi t into the inner sockets of talking machines and it has an enlarged screw threaded member 5 whereby the shank is secured to the needle 4 as clearly illustrated in Fig. 3. The needle .4, if of square configuration 4 as illustrated in Figs. 1 and 2 is provided with four distinct needle points v6, 7, 8 and 9,

each point beingconnected toits adjacent point by means .of the curved surfaces 10, 11, 12 and 13. When these curved surfaces are made of the proper configuration, the points 6, 7, 8 and 9 are formed which are connected to a central point 14 by means of substantially straight portions 15, 16, 17 and 18,,

- these last four portions forming a kind of 5 web which gives strength and backing to the points 6,7, 8 and 9. If desired,.instead of I Specification of Letters Patent. Application filed. May 28, 1912. Serial No. 700,276. r

in Fig. 1.

Patented Nov. 26, 19 1 2:

makin a four sided needle theneedle may be ma e with a smaller or larger number of sides and needle points, one modifiedform beingshownin Fig. 4 wherein there are five needle points 20, 21, 22, 23 and 24! a The needle is used in substantially the same we as any other needle in that its shank 3 1s inserted in the sound box 2 and secured therein by the set screw in the usual 85 manner, the needle having been first moved to such a position that one of the points will be in just the proper position to enter one of the grooves of the record, as illustrated In the practicaluse of my mulw tiple needle, I have found that I get substantially the same volume from each of the needle points as is usually obtained from the use of steel needles and at the same time I aim enabled to provide needle points which give an added brilliancy to all kinds of musical selections, icking up ,.as it does, the finer shadings, W ich with other needles or styli are almost entirely lost. It does not injure'records, but eliminates all scratchin and the metallic blast so common and ob ectionable in steel needles. Acting as a buffer ,'the record is gradually polished and thereby improved, insuring the longest possible life to it. If the wood of which the 5 multipleneedle is made is of box-wood or of similar hard woo-d, the needlepoints' may be used more than once without sharpening; Atthe same time, one of my multiple me 2 dles may be used an enormousmunrber of times by filing and grindin the curved surfaces'lO, 11, 12 and 13 Wit a file or other suitable tool of the proper configuration. Therefore, one or two of my multiple needles and a sharpening tool may be used for a long period of time and the necessity of avoided.

What I claim as my invention is:

keeping on hand boxes of needles is thus 1. A needle for talking machines comprismg a shank and a body projecting from said shank ofrelatively large size compared therewith, said body having a plurality of corners on the bottom opposite the shank forming independent reproducing points, 1 5 and said bottom having a hollow surface forming said points, substantially as described.

2. A needle for talking machines compris- I V ing a shank and a body-projecting therefrom, said body having a plurality of cor-' ners on the bottom of the body opposite the shank forming independent reproducing points, and said bottom having rent-rant surfaces forming said points, substantially as described.

3. A needle for talking machines comprising a shank and a wooden or fibrous body projecting from said shank of relatively large size compared therewith, said wooden or fibrous body having a plurality of cor- 11ers on the bottom opposite the shank forming independent reproducing points, and said bottom having curved surfaces forming said reproducing points, whereby said curved surfaces may be filed or dressed down to renew or sharpen said independent reproducing points, substantially as described.

4. A needle for talking machines comprising a shank and a body provided with a plurality of independent re roducing points connected by reentrant sur aces disposed at a relatively large angle to the longitudinal axis of the needle, substantially as described. I

5. A needle for talking machines comprising a shank and a wooden or fibrous block of rectangular form, the shank being secured at one end of said block and the bottom of said block opposite said shank having rentrant surfaces forming a plurality of independent reproducing points at the corners of the block, whereby the reentrant surfaces-forming the bottom of the block may be filed or dressed down to'renew or sharpen said independent reproducing points, substantially as described.

6. A needle for graphophones or thelike comprising a shank and a wooden or fibrous body projecting therefrom, saidfibrous body having a plurality of independent points connected together by curved surfaces whereby said curved surfaces may be filed or dressed down to renew or sharpen said points, and said points being connected together by webs affording a backing for the points, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.

WALTER B. NICHOLS.
