6 Claims. (Cl. 19-120) The invention relates to combing machines of the Heilmann type and has for its principal objection the provision of an improved mounting for the lower nipper or cushion plate.
It has been proposed heretofore to mount the cushion plate so that it, or a spring plate associated with it, partakes of an upward or rocking movement serving to lift the fringe for penetration by the top comb needles as the upper nipper, or nipper knife, is raised during the forward movement of the nipper assembly but such arrangements have been somewhat complex, mechanically, in some instances, and in other instances the relatively moving parts have been so disposed and located that their operation has been impaired by lint and fly accumulation which has had to be removed frequently to ensure continued operation without impairment of the uniform quality of the sliver.
The principal object of the present invention is to provide a rocking type of cushion plate mounting which is of simple construction and which lends itself to trouble free operation.
More specifically, the invention has to do with a comber of the kind having a nipper frame including side portions connected by a transversely disposed body portion and "Ice movement about the axis of the pivot means. Thus, the body portion 21 of the nipper frame is shown as provided with spaced upstanding ears 22 (Fig. 2) and journaled therein and in the nipper frame side portions are pivot shafts 23. Clamped to the pivot shafts by screws 24 are cars 25 which project rearwardly from the upstanding portion 26 of an angle bar which constitutes a cushion plate support, the cushion plate being secured, as by screws 27, to-the under side of the forwardly projecting flange portion 28 of the support.
The cushion plate support incorporates upper and lower stop faces and the nipper frame body portion incorporates upper and lower stops disposed respectively above and below the stop faces of the cushion plate support'for engagement thereby to limit the rocking movement of the cushion plate and its support about the axis of pivot shafts23. m
having transversely extending pivot means mounted in the nipper frame and comprises a cushion plate support mounted on said pivot means for rocking movement about the axis thereof and incorporating upper and lower stop faces, the said nipper frame body portion incorporating upper and lower stops respectively disposed above and below the said stop faces of the cushion plate support for engagement thereby to limit the said rocking movement and a cushion plate secured to the cushion plate support.
Further features and advantages of the invention will be apparent from the following description of the accompanying drawings, of which:
Fig. 1 is a transverse, vertical section of the head of a combing machine incorporating the invention, with the nippers shown in their rear or closed position;
Fig. 2 is a plan view of so much of the head of Fig. l as is necessary to illustrate the invention;
Fig. 3 is a section on the line 3-3 of Fig. 2; and
Fig. 4 is a section on the line 4-4 of Fig. 2.
Referring preliminarily to Fig. 1 of the drawings, the reference 10 indicatesthe usual oscillating wag shaft by which the nippers are advanced toward and retracted from the detaching rolls 11 disposed above the needles 12 of comb cylinder 13. The upper nipper, or nipper knife, is marked 14, the lower nipper, or cushion plate 15 and the top comb needles 16.
The nipper frame comprises side portions 20 connected by a transversely disposed body portion, generally designated 21. The details of the manner of supporting the illustrated nipper frame form no part of the present invention and, hence, will not be described.
The nipper frame incorporates transversely extending pivot means on which are mounted supporting means for the cushion plate, so that it may partake of a rocking The lower stop face of the cushion platesupport' is the heel or under surface 30 of the support, at the rear of the cushion plate; and the lower stop of the nipper frame for engagement by the lower stop face is the face or shoulder 31 of the nipper frame body portion 21.
The upper stop face of the cushion plate support is the top surface 32 of a boss 33 disposed centrally and formed as an integral part of the upstanding portion 26 of the support; and the upper stop of the nipper frame is a depending screw 34 mounted in the overhanging front end 35 of a bracket 36 which, at its lower end 37, is secured to the rear face of the nipper frame body portion by bolt 38. As will be apparent, the screw 34 is adjustable to vary the extent of the upward rocking movement of the cushion plate and its support about the axis of pivot shafts 23.
The unit consisting of the cushion plate and its support is spring-biased upwardly to engage the upper stop face with the upper stop. For this purpose, recesses or pockets 45 (Fig. 4) are formed in bosses 46 which, like 33, are formed integrally with the upstanding portion 26 of the cushion plate support. The lower or open ends of recesses 45 are disposed in the stop face 30 of the support, so that the lower ends of springs 47 mounted in the recesses engage the lower stop 31 of the nipper frame body portion.
In operation, the descending nipper knife engages the toe of the cushion plate and, compressing springs 47, rocks it and its support to the Fig. 1 position. During the forward movement of the nipper assembly (that is, towards the detaching rolls 11) the nipper knife rises and permits springs 47 to rock the support and cushion plate upwardly to the extent permitted by step screw 34, the
nipper knife and cushion plate assuming the positions in.
dicated in broken lines in Fig. 1. Thus, the rising cushion plate lifts the fringe to the top comb needles and, as will be apparent, the degree of penetration of the fringe by the needles is readily controlled by adjusting screw 34.
As will be seen, the stops and stop faces are all disposed rearwardly of the rear end of the cushion plate and hence are remote from the bite or active zone of the nippers where lint and fly tend to accumulate; and, .consequently, there is little danger of the lint or fly accumulating to excess in the region of the stops and stop faces where it would tend to clog the rocking movement of the cushion plate and hence impair the quality of the sliver.
In the light of the foregoing exemplification of the principles of the invention, the following is claimed:
1. In a comber of the kind having a nipper frame including side portions connected by a transversely disposed body portion and having transversely extending pivot means mounted in said nipper frame, the improvement which comprises: a cushion plate support mounted on said pivot means for rocking movement about the disposed between the lower stop and stop face and biased to rock the cushion plate support upwardly to engage its upper stop face with the said upper stop of the nipper 1 frame body portion.
3. The improvement of claim 1, in which'the upper stop face of the cushion plate support comprises a boss formed integrally therewith and in which the upper stop of the nipper frame body portion comprises :1 depending screw adjustable to vary the extent of the upward rocking movement of the cushion plate support.
4. The improvement of claim 1, in which the cushion plate support comprises an angle bar having an upstanding portion, the upper end of which constitutes the upper stop face, a heel portion which constitutes the lower stop face and a forwardly projecting flange portion to which the cushion plate is removably secured.
5. The improvement of claim 1, in which the lower stop of the nipper frame body portion is constituted by a shoulder formed thereon and the lower stop face of the cushion plate support by a face incorporating a recess and in which a spring is disposed in the said recess with its lower end abutting the said shoulder.
6. The improvement of claim 1, in which the said stops and stop faces are all disposed rearwardly of the rear end of the cushion plate.
