Definitions

  • This invention refers to the condensing or reducing devices for the textile rovings or slivers applicable to the drawing mechanisms in spinning machinery and constitutes an improvement 5 in or modification of the subject matter of my copending applications Serial No. 440,517 and Serial No. 521,791.
  • Said co-pending applications refer to a roving reducer which is applicable to the drawing cylinders of textile rovings and is characterized by the feature that the piece in the form of a funnel which acts as reducer of the roving, is quite free without being coupled to any supporting member and rests solely on the bottom drawing cylinder.
  • These reducers are connected together in twos corresponding to two adjacent drawing mechanisms and this union or coupling is effected in such a manner that each of the two reducers has freedom of movement in relation to the other so that each one of them may be able to adapt itself independently to the position of its respective roving.
  • the present invention relates tocertain improvements which give the roving-reducer an arrangement that is much more practical and convenient to handle and which at the same time ensure the convenient positioning of the reducer in all cases, without the latter being able to fall when the top cylinder is withdrawn.
  • This invention essentially consists in permaently connecting the uniting tube of the reducers with a frame or'retaining piece, preferably made of a stamping of light metal, which forms on the front part an extension or handle by which the operative can take hold of the reducer and place it in its position and also forms towards the rear 50 part two branches or extensions which rest on the bottom intermediate cylinder and has downward projections which are normally at a very small distance from the bottom drawing cylinder and prevent the reducers from falling when the top drawing cylinder is withdrawn.
  • This frame or retaining piece has holes through which the tube. for uniting the reducers passes, and both these holes and the uniting tube have a shape such that the reducerscan move parallel to the cylinders but cannot rotate in relation to the retaining piece through more than the small angle which allows of the play existing between these pieces.
  • Fig. 1 is a perspective view of a pair of reducers placed in the working position in relation to the drawing cylinders and to the lower interplan and longitudinal section a method of mounting the reducers on a coupling tube which allows the reducers to be changed.
  • each pair of reducers consists of two reducers 1 each of which carries a coupling rod 2 permanently fixed thereto and these two rods are coupled together by means of an exterior tube or sleeve 3.
  • each of the rods has a certain amount of longitudinal play and can also rotate on its agris through a small angle so that each of the reducers can adapt itself with complete freedom to its corresponding pair of cylinders and take up exactly the position that corresponds to the position of the roving.
  • the tube 3 which couples the pair of reducers 1 together is combined with a frame or retaining piece which, as a whole, is designated by the numeral 46.
  • This retaining piece is preferably constructed of a stamping of light metal and in such a manner that it has sufficient rigidity without its weight being excessive, and presents two rearwardly directed branches 48 of a length that is sufficient to enable them to rest on theneck of the bottom 2 intermediate cylinder 5 and at the front part forms an extension 4'7 which constitutes a handle by which the operative can easily take hold of the whole of the two reducers and the retaining piece and position them in the spinning machine.
  • the two-rear branches 48 of the retaining piece have between them a space 50 which is sufllcient to enable the pressure-transmitting rod of the spinning machine, which transmits the pressure to the top, cylinders of the drawing mechanism,
  • the tube 3 has a rib 51 and that the holes 67 of the side faces of the frame 46 have, corresponding to this rib 51, a notch 52, but, for the same purpose, the
  • tube 3 could be of a square, hexagonal or anyother non-circular section and the holes 67 have a corresponding shape.
  • the reducers 1 in the working position the reducers 1 remain enclosed in the angle which is formed between the drawin cylinders 6 and 7 and the piece-46 rests with its rear branches 48 on the neck of the rear. intermediate cylinder 5.
  • the bottom projections 49 3 remain at a small distance from the bottom drawthe top cylinder 7 is withdrawn without interrupting the working of the machine, the cylinder 6 drags the reducers forward but the projections 49 meet this cylinder 6 and prevent the reducers from advancing and falling over the front part.
  • the projections 49 may be omitted and the ends 61 of the branches 48 curved downwards. In this case, when the reducers run forward, the curved parts 61 meet the slipping cylinder 65.
  • the adaptation of the reducers 1 to the angle formed between the cylinders 6 and 7 is obtained in the first place by the friction of the bottom cylinder 6 against the bottom faces of the reducers and is, to a certain extent, assisted by the friction between the rear branches 48 of the retaining piece and the neck of the bottom intermediate cylinder 5.
  • small supplementary weights or masses 53 may, as shown in Pig. 5, be arranged in the ends of the branches 48.
  • these weights are supposed to consist of pieces of wire or rod 53 of suitable material which have grooves 54 in their ends and the plate of the branches 48 engages in or is stamped into these grooves, so that it suitably conflnes the rods 53. Nevertheless, as may be understood, these weights could be arranged in any other suitable manner.
  • weights increase the pressure which the branches 48 exert upon the intermediate cylinder 7 5 and, therefore, the propelling action that this cylinder develops on the piece 46 in order to apply the reducers 1 in the angle between the oriinders 6 and '7.
  • weights 53 By suitably regulating the weights 53, there can be obtained for each type of apparatus the suitable force for exactly applying the reducers to the drawing cylinders.
  • Figs. 7 and 8 represent a method of detachably coupling the rods 2 of 'the reducers with the coupling tube 3.
  • the ends of the tube 3 havediametral cuts or slits 55: which divide them into two branches 58 and 59 that can be operated in order to allow the rod 2 to be removed.
  • branches 58 and 59 In one of these branches there is made a recess or depression 56 which forms a projection for the inner part of the tube, which projection engages in a notch 57 made in the coupling rod 2.
  • the two branches 58 and 59 of the coupling tube are kept closed by means of a ring 68 as shown in Fig. 7 and, when it is desired to remove the reducer 1, this ring-60 is disconnected and placed as shown in Fig. 8, and, by rotating the re-] ducer 1 and the rod 2, the full part of the rod corresponding to the notch 57 raises the protuberance 56 and separates the branch 58 of the tube, so that the rod 2 with the reducer 1 can be removed.
  • This ring 60 may form the ridge or stop for the purpose of preventing the piece 46 from escaping from the tube 3.
  • a pair of reducers to rest upon the lower drawing cylinder a sleeve for connecting the reducers to permit movement of the reducers with relation one to another
  • a frame means carried by the frame for supporting the sleeve, rearwardly projecting arms formed in the frame to rest upon the intermediate cylinder, downwardly extending side members integral with said arms to limit the forward movement of the frame, and an outwardly projecting handle formed in the front of the frame to permit inserting or withdrawing the frame from the machine.
  • a pair of reducers to rest upon the lower drawing cylinder, a sleeve for connecting the reducers to permit movement of the reducers with relation one to another, a frame, means carried by the frame for supporting the sleeve, a pair of straight arms formed in the frame, weights fixed whereby the weights contribute to hold the reducers in the angle formed between the drawing cylinders, and means for limiting the forward movement of the frame formed integral therewith.
