Definitions
- My invention relates to apparatus or spindles for doubling or twisting textile fibers by double torsion which'is essentially composed of a bobbin for the doubled threads, or the threads to be doubled, supported by a strap or carrier about whichl be horizontal or inclined, this apparatus can only function regularly 1f 1. the said carrier is maintained stationary.
- My invention relates to a doubling or twisting apparatus operating by, double tor- 2c sion and characterized by the use of safety vdevices by which the mechanism is automatically stopped on the occasion of any disturbance to the regular operation of the apparatus, and such safety devices may comprise:
- said elements are subjected vto the disturbances occasioned in the apparatus, and are adapted to make contact with the aforesaid contact elements of the rotor, in case of any '85 disturbance to the functiono g.
- rotor may comprise two electrically conduct- 60 ing 1ings which are insulated from one anthe rotor; said' circuit can be' closed by said contact elements of the stator. 40- 'if any trouble occurs, and it comprises a deother. and also from the rotor, which rings are placed side by side and are permanently connected to the external electric circuit.
- a forked contact member ldrawn by the stator in its motion is disposed in such manner as to make contact with the said conductlng rings when the stator departs from the w normal position.
- a contactv member mounted opposite the two contact rings of the rotor, it being disosed upon a movable member which is sub- ]ected on the one hand to the tension of the 55 fibers to be twisted which travel'upon said member,.and on the other hand to the action of antagonistic means such as a spring, saidmovable member being vso disposed that the said movable contact member will make contact with the said contact element of the rotor when the tension of the fibers exceeds a given amount.
- My invention further relates to a modification of the preceding mechanism in which the5 antagonistic member combined with the movable guide subjected tol the tension of the fibers is provided with regulating means, in g5 order that yarns ofvarious kinds may be twisted in the same doubling machine.
- ⁇ Fig. 1 is an'axiaj'. longitudinal section of the entire apparatus.
- Fig. 2 is a similar section showing in detail the safety arrangement and the electric circuit with which it is connected.
- Fig. 3' is a section along the line III-III of Fig. 2 showing the rings and the friction contact elements for supplying the current to the rotating parts.
- Fig. 4 is another section, on the line IV-IV of Fig. 2, of the friction contact elements sedescribed in the hereinabove mentioned application; as in this apparatus, yarn a to be doubled is wound on a bobbin 1 supported by a carrier 2 rotatable on journals 3 and 4 of a rotating cylinder 5 which is provided with two end plates 6 and 7, a peripheral opening 8 for introduction and removal of the coil, and a second similar orifice which cannot be seen in the drawings, diametrically opposite the former relative tothe axis
- the yarn leaving the bobbin 1 passes through the journal 3, round a pulley 9 in a tubular duct 9 secured to the rotating cylinder 5 and returns over a pulley 9 through the opposite journal 4 whence it emerges and is entrained by a suitable drawing apparatus.
- Bearings 3 and 4 support the journals 3 and 4.
- a pulley 10 actuated by a motor 11 (Fig. 2) imparts the desired rotational movement to the cylinder 5 by means of a belt not shown.
- a contact arrangement which is mounted on one of the journals 3 consists of two contact rings 12, 13, electrically insulated from the journal by insulating elements 14, 15, 16 and from one another by an insulating ring 17.
- Insulated electric conductors 18,19 positioned in a channel 20 in the journal 3 are connected with contact rings 21, 22 arranged externally of the vdrum 5 of the apparatus on the journal 3, these rings being also insulated from the journal 3 by insulated mountin s 23, 24.
- a switch 31 mounted in this circuit and connected with magnetic core 32 actuated by contact a coil 33 is inserted in the circuit of the conductors 29, 30 which are mounted in shunt on the distribution circuit 34, 35 feeding the motor 11.
- the arm 37 participates in this movement and one of the branches of the bridge member 39 comes into contact simultaneously with the two rings 12, 13 and thus closes the electric circuit through the ycoil 33; then, the interyrupter 31, 32 is operated, the current flowing through the motor 11 is cut ofi', and the spindle is thus stopped.
- the rod 43 oscillates about the pivot 44, thereby re-connecting electrically the rings 12, 13, and thus the electric circuit is closed through the coil 32 and the switch 31 acts as in the previous case.
- the arrangements described above can be modified in numerous Ways, and the various elements constituting the same may be differently constructed, thus for example, ⁇ instead of the bi olar contact arrangement described, a unipo ar contact devicemay be used, the return being effected. through the metal of -the apparatus.
- the apparatus may also be constructed so as to comprise only one of the arrangements described namely, that responding to the movements of said carrier or that responding lto an excess -f a projection 36 carrying an arm 37,
- the electric circuit utilized may be a direct current or alternating current c1rcu1t, etc.
