NEEDLE.

Specification of Letters Patent.

Patented Apr. 27, 1920.

Application led Hay 5, 1919. Serial No. 294,720.

To-aZZ whom it may concern:

Be it known that I, CHARLES A. PORT, a citizen of the United States, and a resident of Windsor, in the county of Henry and State of Missouri, have invented certain new and useful Improvements in Needles, of which the following is a specification.

My invention is an improvement` in needles, and has for its object to'provide means for firmly holding a filament of wire and for connecting the said filament to the needle holder of a talking machine, in such manner that the wire may be used to engage the record.

In the drawings:

Figure 1 is a plan view of the holder with the wire in place,

Fig. 2 is a longitudinal section,

Fig. 3 is a perspective view of the pawl mechanism,

Fig. 4 is a longitudinal section with the cap and ring removed,

Fig. 5 is an end view Fig. 6 is a similar view other end,

Fig. 7 is a perspective view of one of the holding pawls.

The present embodiment ofthe invention comprises a cylindrical shank 1 having its ends reduced as shown at 2 and 3, and. having an axial bore 4 forv receiving the filament 5 of wire. The body has a longitudinally extending radial slot onpassage 6 from the bore, extending the full length of the looking at the 0 Y- Within this slot is arranged a bar 7 which is ofa width slightly less than the depth of the slot, and this bar has on one edge, namely that adjacent to the filament struck-up lugs or pawls 8 for engaging the filament. the said pawls being resilient, and having their points extending slightly beyond the edge of the bar,'to engage the filament prior to the engagement of the bar edge therewith.

The bar is split longitudinally at each end, to formpairs of arms 9-10, 11-12, the members of each pair diverging slightly as shown in Fig. 3. The free end of the arm 10 at the edge adjacent to the filament has teeth as shown for engaging the filament, and the arm 9 at its free end has a pair of' lugs 13, the members of the pair being spaced apart from each other to receive between them a ring 14. This ring encircles the body at the reduced portion 2, and the said ring has a key way 15, which when lbetween the lugs 16 and 17.

looking at one end,4

register with with the lugs 13 will turned into ,register to permit the ring to permit their passage, be removed.

The arm 11 has a', lug 16 at its free end, and a rounded cam lug 17, adjacent thereto but spaced apart therefrom, and a ring 18 is provided for engaging the reduced portion 3 of the body, the said ring engaging At that end of `the body adjacent to the ring 18, the said end flares Yfrom the bore 4 as indicated at 19 opposite. the slot 6, and a holding pawl 20 is arranged near bore having a recess 21 for receiving this pawl 20, and the recess being of such depth that the teeth will extend into the bore into engagement with the filament.

In use the filament is arranged in the bore of the body as shown in Fig. 2, and the bar 7 is placed in the slot 0r passage 6 as shown in Fig. 2, with the spring pawls 8 in engage ment with. the filament. The filament may be advanced to the proper vdistance beyond that end of the body which is adjacent to the ring 14, and the rings. 14: and 1S are placed on the reduced portions 2 and 3 of the body. The pawls 8 and 20 and the teeth of the arm. 10 hold the filament from reverse movement, while the rings 14 and 18 by their action on the bar hold the filament closely in place in the body. The filament can be advanced when desired without removing-the bar, by turning the collar 14. Vhen this collar is turned so that the key way 15 registers with the arm 9, the arm may swing outward into the key way, thus relaxing pressure of the arm 10 on the fila-v ment, and permitting the filament to be easily advanced. 'By pressing the arm J inward with the key way of the collar in the arm, the collar may be slipped over the lug 13. The arms 9 will now swing outwardly releasing the pressure on the filament which may be easily advanced. Referring to Figs. 3 and 7 it will be noted that the teeth of the pawl 20 and of the arm 10 face toward that end of the body adjacent to the collar 14, and the said end of the body is tapering as shown.

Referring to the drawing, it will be seen that the arm 11 is another lug 2Q on the inner side of the front lug 17 which coperates with the lug 16, as bumpers for regulating the length of wire to be fed each time when the point is worn'. The lug 17 is slightly oval or rounded, and acts as a lock so the the opposite end, the

bar cannot work back, moving only when forced back by the thumb and finger collar 14, which fits in the lugs 13 onthe arm 9. The bar must Work backward and forward, the teeth 20 and 10 acting as ratchetsor pawls.

I claim z l. A device of the character specied,' com.. prising a substantially cylindricalA body, hav.-l

a slot or passage ex-n the bore and `.extending an axial bore and tending radially from ing the full length of the body, said bore being adapted to receive a filament fof Wire for the purpose specified, va bar in .theA slot or passage having means for engaging andholdino' the filament against movement away om the record, and means for clamping the bar in the slot or passage, said means comprising rings engaging the body, the bar having lugs for limiting the movement oi' the rings longitudinally of the body, one of the rings having a key Way for permitting thel passa ,e of the lugs.

2. A evice of the character specified,

comprising a substantially cylindrical body havin exten ingradially from the bore-and extending the'full length 4of the body, said bore being adapted to receive a filament of Wire for, the purpose specified, ya bar in the slot or passage having means for engaging and holding the filament against movement ,away from Athe record,`and means for clamping the bar in the slot or assa e.
