Definitions

  • the mechanism forming the subject of this invention completely obviates these disadvantages, since in it the pressure is transmitted to the rollers from above Without there being any pressuretransmitting member situated between the table of the machine and the rollers of the drawing mechanism, and without it being necessary to alter the usual construction of the top rollers and of the cap bar neps or grooved supporting frames in which the journals of these top rollers slide. As a result of this construction, the table of the machine remains completely free, and can always be kept clean without any difficulty.
  • this mechanism enables the drawing rollers to be relieved at will with great facility, and in such a way that it is possible in a simple manner to unload and raise the front roller in order to tie a broken roving while still continuing the pressure on the other rollers; or
  • rollers can be relieved si-' multaneously by raising, with a very easy movement, all their pressure members; and finally the cap bar neps or supporting frames of the top rollers can also be raised whenever this may iii) ell)
  • the mechanism according to this invention is characterised by the feature that all parts of the pressure mechanism are mounted above the bar which usually runs through the rear part of the machine, behind the rollers of the drawing mechanism, and which sustains the cap bar neps or supporting frames of the top rollers.
  • this bar Upon this bar are mounted, according to the present invention, not only the frames supporting the top rollers, but also certain arms which carry the pressure mechanism, and a support which carries a helical spring, which is the member that produces the pressure that weighs down the rollers.
  • Some of these members are rotatably mounted upon the bar, and retained by means of latches which can be released at the appropriate moment, and other members arepermanently fixed to the bar and can oscillate rotationally jointly with the bar, which for this purpose is rotatably mounted upon bearings on the roller stands.
  • Figure 1 of these drawings represents a section of the mechanisms by a plane perpendicular to the axes of the rollers
  • Figure 2 is a view from the rear of the mechanism, looking in the direction of the arrow II in Figure l.
  • the apparatus illustrated by way of example in the drawings comprises four pairs of rollers, l and 2, 3 and 4, 5 and 6, and l and 8.
  • the rollers I, 3, 5 and I are actuated conveniently by the machine, the top rollers 2, 4 and 8 are weighted by the pressure mechanism forming the subject of this invention, and the top roller 5 is assumed to be a slipping roller of small diameter for accompanying the fibres.
  • the mechanism may comprise, in a manner al-' ready known, fibre-propelling members of any appropriate type between the rollers 3-4 and when required, and the part I2 weights the two 3 rear rollers 2 and 4.
  • this double saddle H, l2 receives pressure by means of a lever [23, which arranged above the rollers, is rockable about a pivot l6, and is articulated by its front *7 end to the saddle I I at II.
  • This lever in its turn receives pressure from a spring 18, which acts upon its rear end.
  • the pivot [6 of the lever I is mounted in the interior of a hollow arm 2
  • This bar 20' is parallel to the rollers, and is arranged in the rear part of the mechanism, mounted upon supports 22 fixed by means of screws 23 to the roller stands ID of the machine.
  • this bar 20 is provided with a plane longitudinal face 24, which facilitates the fixing thereto of the various members that have to be mounted upon it simply by means of conical pins 25.
  • is mounted loose upon the bar 20, and between the two lateral walls of this arm is arranged a supporting block 26, which is fixed to the bar by means of a pin 25.
  • This block is provided with a notch 21, in which engages a latch or catch 28, mounted upon the arm 2
  • the member 28, fixed, as has been stated,- to the bar 20, is provided, in the interior of the arm 2 i, with a prolongation 30, in the interior of which is mounted the spring [8, which by means of a plunger 3
  • the bar also carries mounted thereon the cap bar neps or supporting frames of the top rollers, and to this end, between the two branches formed by the support 22 of the roller stand, is mounted, as shown in fuller dew tail in Figure 2, a member 32 fixed to the bar by means of a pressure screw 33, and having a prolongation 34 with a rod 35, upon which are mound ed the supporting frames of the top rollers.
  • hollow arm 2! carries on its end a latch 36, which is close to a tooth 31 on the pressure saddle H, for the purpose of keeping this saddle raised and thus relieving the front roller 8.
  • the bar 20 may be in one piece, which extends to the entire length of the machine, or may be divided into a number of sections, and carriers, fixed on each of these sections by means of a pin 25, a hoop provided with a prolongation 4! carrying an adjustable abutment screw 42, which cooperates with a latch 43, which is so mounted upon the roller stand 10 as to be freely rotatable about a pivot 44, and is actuated by a dependent counterpoise 45.
  • the assemblage is arranged in such manner that in the normal position. by
  • a pressure mechanism for the rollers of spinning and preparation machines having a drawing mechanism mounted on a roller stand and rear bar mounted on said roller stand adjacent said drawing mechanism, an arm having one end rotatably mounted on said rear bar, said arm being located above the rollers, a lever pivoted intermediately of said arm, a pressure saddle for loading the rollers, one end of said lever being articulated to said pressure saddle, and a spring mounted on said rear bar actuating the other end of said lever in such a way that by raising the arm around its pivot and rotating it around the rear bar the saddle is likewise raised, and all the rollers are relieved, without having to relax or dismount the spring.
  • a fixing latch on said arm adjacent with and cooperating with said rear bar which, in the normal position, rigidly unites said arm with the rear bar, but readily permits disengagement thereof when the arm is to be raised.
  • said pressure saddle comprising a front member articulated directly to the end of the lever on the arm and directly loading the front roller, and a rear member loading the rear rollers articulated to said front member, a tooth on said front member, a latch on the end of said arm adjacent said tooth, said tooth adapted to cooperate with said latch and permit said latch to engage said tooth to raise said front member of the saddle thereby unloading the front roller without unloading the rear rollers.
  • a supporting block carried by said rear bar of the drawing mechanism rigidly fixed thereto, and forming a support for the pressure spring that acts for loading the rollers.
  • a member carried by said rear" bar rigidly fixed thereto, and supporting frames for all the top rollers of the mechanism carried by said member.
