RICHARD H. JONES, OF CHICAGO, ILLINOIS.

. TALKING-MACHINE NEEDLE.

Patented Apr. 15, 1913.

Application filed April 26, 1909. Serial No. 492,205.

To all whom it may concern Be it known that I, RICHARD H. J ONES, a citizen of the United States of America, and resident of Chicago, Cook county, Illinois, have invented a certain new and useful Improvement in Talking-Machine Needles, of which the followin is a specification.

My invention re ates to improvements in talking machine needles and has for its object the production of a device by means of which the sound may be accurately produced.

A further object is theproduction of a needle that will not wear the record.

A further object is-the production of a needle that may be used an indefinite number of times without appreciable deterioratron.

These and such other objects as may hereafter appear, are attained by my device, embodiments of which are shownin the accompanying drawings in which:

Figure 1 represents a side elevation of the rough material from which my device is made. Fig. 2 represents a plan view of Fig.

' 1. Fig. 3 represents a plan view of a com pleted needle. Fig. 3 represents a side elevation of Fig. 3. Fig 4: represents a plan view of a modified form of needle. Fig. 4 represents a side elevation of Fig. 4. F1 5 represents a perspective view of a talking machine equipped with my device.

Like numerals of reference indicate like parts in the several figures of the drawings.

Referring now to the drawings- 7 represents an example of the crude material preferably used in the manufacture of my improved needle which in this particular case '18 the thorn or spine from certain species of cactus. An ordinary thorn such as shown in Fig. 1, is cut into sa three arts as shown at 89 and a stylus ormed t erefrom having a substantia ly triangular end flaring at 10, terminating in a kmfe edged end 11; the base of the needle is prefera ly roundhd as shown at 12, adapted to fit. with in the reproducer.

Referring now to Fig. 5-43 represents the talking machine box, 14 the horn su port, 15 the horn, 16 the reproducer, 17 t e iaphragm from which the arm 18 extends. On this arm ismounted a frame carrying the needle 19. The record disk 20 is shown in a position to be operated-u on. In Figs. 4" and 4" I have own a modi maintain a uniform and fied form of needle in operati end is elongated into a point 21, tapering gradually backward to the thicker part 22.

I make no claim of novelty in any of the parts of the machine except the, needle and its combination with the machine.

I am aware that needles of ivory and of metal have heretofore been used, all of which. are more or less harder than the record disk and'consequently their use wears out the record. I amalso aware that needles of wood or fiber have been used, all of which have been softer than the record disk and consequently have been quickly worn out in playing, in fact in some instances a needle will not last through a half of'some records.

I have invented a needle made from the cactus of the same degree of hardness as the record itself and b its use not only do I not wear out the record but the needle itself may be used a great number of times. This is a very important consideration; in the first place many records are of great value and often irreplaceable, while in the second place the user is not obliged to keep replacing a worn out needle with a freshonc -besides as the softer needle deteriorates, so

also the quality of the music becomes less pleasing to the ear. By the use of my improved needle' however, I am enabled to pleasing excellence of rendering.

I claim:

1. A reproducing needle formed from the spine of the cactus.

2. A reproducing needle formed from the spine of the cactus of the same degree of hardness as the record disk.

3. In a talking machine, the combination with a reproducer of a record disk and a reproducing needle formed from the spine of the cactus.

4. In a talking machine, the combination with a reproducer of a record disk and a re roducing needle formed from the spine 0 the cactus of the same degree of hardness asssiatid d t t oh o k igne y me a lcago, 00 county, Illinois, this 15th day of April, 1909.
