Description
Oct. 28, 1958 I E. A. FEUSTEL YARN CARRIERS FOR KNITTING MACHINES Filed Aug. 19, 1954 INVENTOR. HA/E T A. FE'USTEL dhxuk w United States Patent 2,857,751 YARN CARRIERS FOR KNITTING MACHINES Ernest A. Feustel, Hasbrouck Heights, N. J. Application August 19, 1954, Serial No. 450,970 3 Claims. (Cl. 66-126) This invention relates to yarn carriers for full fashioned hosiery knitting machines and refers more particularly to carriers of the type where a fine bore yarn guiding tube is removably mounted in a carrier finger.
In the course of the operation of a full fashioned hosiery knitting machine it sometimes becomes necessary to remove quickly a damaged yarn-guiding tube and to substitute it by a new one. Furthermore, it is often necessary to preserve the guiding tubes from being damaged by impact with the sinkers of the machine.
An object of the present invention is to provide a yarn carrier finger, the tube of which can be easily inserted or withdrawn and which is so mounted that it can withstand an impact of substantial force.
Other objects of the present invention will become apparent in the course of the following specification.
In accomplishing the objects of the present invention, it was found desirable to provide a yarn carrier finger which has a pair of opposed jaws at its lower end, the slit extending between the jaws which have an intermediate recess of larger width. The finger is used in conjunction with a fine bore yarn-guiding tube of a corresponding shape, namely: a tube provided with a flange of larger diameter which fits into the recess.
The invention will appear more clearly from the following detailed description when taken in connection with the accompanying drawing showing, by way of example, a preferred embodiment of the inventive idea.
In the drawing:
Fig.1 is a perspective view of a yarn carrier finger constructed in accordance with the principles of the present invention;
Fig. 2 is a longitudinal sectional view of the finger;
Fig. 3 is an enlarged fragmentary view of the lower portion of the finger;
Fig. 4 is an enlarged transverse sectional view taken along the line 4-4 of Fig. 3 looking in the direction of the arrows.
Fig. 5 shows a yarn guiding tube.
Fig. 6 illustrates a modification of the yarn guiding tube.
The yarn carrier finger shown in the drawing has an elongated body 11 having a top portion 12. The finger has a curved zone 14 located close to, but at a distance from, the lower end 17 of the finger. An elongated aperture 15 is located essentially at the curved zone and communicates with the yarn-guiding groove 13. A lower portion 16 of the finger extends between the aperture 15 and the lower end 17.
As best shown in Figs. 3 and 4, the lower portion 16 of the finger has an elongated slit 18 which extends from the aperture 15 to the lower end 17. The slit 18 divides the lower portion 16 into two opposed jaws 19 and 20. The jaws 19 and 20 have opposed surfaces 21 and 22.
"ice
which face each other and which form grooves of essentially semi-circular cross section. Due to this arrangement a tube 23 may fit firmly in the grooves 21 and 22 and will be held by friction between the jaws 19 and 20.
In accordance with the present invention the slit 18 has a recess 24 of larger diameter. Preferably this recess has spherical or curved surfaces 25 and 26 which join the grooves 21 and 22.
The tube 23 has a central flange 31 having a spherical surface which fits into the above described recess. Tubular portions 35 and 36 which may be approximately the same length extend on opposite sides of the flange 31. The portion 35 may have a flared flange 37 to facilitate the insertion of the thread. The portion 36 may have a smaller diameter than the portion 35.
It is apparent that the tube 23 is so constructed that its flange 31 will fit conveniently into the recess 24 of the finger. As shown in Fig. 3, the portion 36 of the tube will project below the end 17 of the finger, while the portion 35, will extend into the aperture 15.
Fig. 6 shows a thread-guiding tube 40 having two flanges 41 and 42 fitting into corresponding recesses formed in acarrier finger (not shown).
It is apparent that the example shown above has been given solely by way of exemplification and not by way of limitation and that it is subject to many variations and modifications without departing from the scope or intent of the present invention. All such modifications and variations are to be included in the present invention.
What is claimed is:
1. A yarn carrier finger for knitting machines, comprising an elongated flat body curved adjacent to and at a distance from the lower end thereof, said body having formed therein an elongated aperture at substantially the curved portion and a slit extending from said aperture to said lower end, whereby the portion of the finger between the aperture and the lower end constitutes two opposed jaws, opposed surfaces of said jaws being inwardly curved, whereby a substantially cylindrical space is formed, and a tube-engaging concave recess located intermediate the ends of at least one of said jaws and having a larger width than the diameter of said cylindrical space.
2. A yarn carrier finger for knitting machines, comprising an elongated flat body curved adjacent to and at a distance from the lower end thereof, said body having formed therein an elongated aperture at substantially the curved portion and a slit extending from said aperture to said lower end, whereby the portion of the finger between the aperture and the lower end constitutes two opposed jaws, opposed surfaces of said jaws being inwardly curved, whereby a substantially cylindrical space is formed, and a recess having spherical surfaces extending to said curved jaw surfaces, said recess being located intermediate the ends of at least one said jaw.
3. A fine-bore yarn guiding tube for insertion into a yarn carrier finger, said tube having a substantially centrally located flange having spherical surfaces, said flange geing adapted for insertion into a recess of a yarn carrier nger.
