' 8 Claims. (Cl. 19-142) The present invention relates to drawing mechanisms of textile machines and in particular to an apparatus for supporting a top roll of the drawing mechanism.
One of the objects of the present invention is to support the top roll of a drawing mechanism in such a way that it will automatically align itself properly with the bottom roll associated therewith.
Another-object of the present invention'is to provide a means for protecting the bearing of the top roll from foreign matter.
A further object of the present invention is to provide an easily accessible means for lubricating the top roll bearing.
An additional object of the present invention is to provide a top roll support means which permits the top roll to rest by' gravity on the bottom roll associated therewith to be driven by this. bottom roll and which at the same time enables the top roll to become automatically aligned with the bottom roll so that the top roll axis will be parallel to. the bottom roll axis.
A still further object of the present invention is to support the top roll in such a way that it may be simply and easily removed from the rest of the apparatus.
Yet another object of the present invention is to provide a top roll support capable of accomplishing all of the above objects and at the same time being made up of simple and ruggedly constructed parts which provide a reliable operation.
With the above objects in view, the present invention mainly consists of a drawing mechanism for textile machines, this drawing mechanism including a top roll means formed with an axial bore and a bearing means located in the axial bore to support the top roll means for rotation about its axis. A support means is connected to the bearing means for supporting the top roll means for free movement along a first arcuate path extending toward the drawing plane and a second arcuate path substantially parallel to the drawing plane.
The novel features which are considered as character'- istic forthe invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, Will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings, in which:
Fig. l is a fragmentary partly sectional view showing a top roll support constructed in accordance with the present invention;
Fig. 2 is an elevational View of the top as seen from the left side thereof; and
Fig. 3 is a side view of a top roll guiding arm of a slightly different construction from the arm shown in Figs. 1 and 2.
Figs. 1 and 2 of the drawings show a top roll 11 which is adapted to rest on a bottom roll 11, partly shown in Fig. 2 of the drawing mechanism to be driven thereby.
roll of Fig. l
The top roll 11 has a weight sufi'icient to provide the necessary pressure between the top and bottom rolls. The top roll 11 is formed with an axial bore in which a tubular member 10 is located, this member 10 being fixed to top roll 11 so as to rotate therewith and in efiect form a part thereof.
The tubular member 10 is itself formed with an axial bore having portions of different diameters. Thus, the portion 103 of this axial bore at the right hand end thereof, as viewed in Fig. 1, is of the smallest diameter and. adjoins at its left end a bore portion 102 of a larger di-- ameter which in turn adjoins at its left end a bore por tion 101 of a still larger diameter, shoulder 104 being;
and beyond sleeve 19 into bore portions 101 and 102,
this shaft 17 also being formed with a pair of annular groovesv in which ball members 18 are located so that the. parts 17-19 form a ball bearing support which allows the top roll means 10, 11 to freely turn about its axis.
A tubular shaft 16 is press fitted at its right hand end, as viewed in Fig. 1, on the left end portion of shaft 17, and a pair of annular projections 161 and 162 extend from the outer surface of shaft 16 up to the inner face of tubular member 10 and up to the inner face of the left end portion of bearing 19, as viewed in Fig. 1, so as to prevent foreign matter from gaining access to bearing 19 through the bore portion 101. A lubricating means, such as a grease fitting 20, is fixed'to the tubular member 10 over bore portion 103 so as to seal the space at the right of bearing 19, as viewed in Fig. 1.
A top roll guiding arm 12 has an intermediate substantially straight portion and a pair of opposite end portions 122 and 123 which are perpendicular to the intermediate portion thereof and which extend in opposite directions from opposite ends of this intermediate portion, respectively. The end portion 123 has its free end formed with a bore through which shaft 16 passes and located opposite the bore portion 101 against a shoulder of shaft-16, this shaft 16 being threaded at its free end and carrying a lock washer 15 and a nut 14 to fix the guide arm 12 to the shaft 16 in the manner shown in Figs. 1 and 2.
It will be noted that the straight end portion 122 of arm 12 is parallel to a central plane a-a of the top roll normal to the axis thereof and that the intermediate portion of arm 12 is located opposite the outer working face of roll 11, is parallel to the axis of the top roll, and extends up to the plane aa, the free end portion 122 of arm 12 being located in plane aa. The end portion 122 of arm 12 is formed with a bore 121 through which a U-shaped rod 22 extends, this rod 22 having one free end 222 which extends into a recess of a stationary frame part 13 and having a threaded free end 223 extending through a bore of frame part 13 and carrying a nut 24 which fixes rod 22 end portion 122 of arm 12 in plane a-a about the curved part of rod 22 passing through bore 121 enables the top roll means 10, 11 to be freely turnable along an arcuate path in the direction of arrow A extending downwardly toward the drawing plane. On the other hand, the capa Patented Dec. 18, 1956 to and'carry in'g said rodt bility of. arm 12 to move freely along axis bb of rod 22 whose center is at enables the top roll means 10, 11 to move freely along a second arcuate path in the direction of arrow B which is parallel'to the drawing plane. Thus} the'top roll 11 is capable of automatically aligning itself withlthe bottom roll so as" to have'its axis parallel to the bottom roll axis, and also the top roll can freely rest with its own weight on the bottom roll.
the top roll so'that the grease fitting 20 is free'ly-accessible and that the'annular projections 161 and 162 as well as the fitting 2ti-protect the bearing 1719" from foreign matter. Also, it is a simple matter to accommodate bear 'ings of various lengths within'the tubular member 10.
Although the top roll of Fig. 1 may be removed from frame part1? by removal of nut 24 and from arm 12' by removal of nut 14, the guide arm '36 of Fig. 3 provides an even easier removability of the top roll since the portions 301'and'302, respectively correspond to portions 122 j and 12-3 of arm 12, are respectively formed with substantially L-shaped cutouts through which the rod 22 and a shaft 16 respectively extend, arm 30 being otherwise iden tical with arm 12'and connected to the apparatus in the same way. Thus, with a guide arm 30 it isonly necessary to move part 301 ofi rod 22 which passes through the It should-be noted that the guide arm 12 is. located on only'one side" of bearing meanslocated in saidbore to support 'said top roll means for free rotation about its axis; a shaft fixed to saidbearing means and extending through one end of saidaxial bore beyond said top roll means; an elongated guide arm having an intermediate substantially straight portion and a pair of opposite substantiallystraight end portions substantially perpendicular to said intermediate portion and extending in opposite directions from' opposite ends of said intermediate portion, respectively, one,
of said end portions having a' free, end lea-area op osite said one end of said bore and fixed tofsaid shaftaaud said intermediate portion being located opposite the outer 'working face of said top rollmeans,"beingisubstantially parallel to the axis of said top roll means, and extending L-shaped cutout of portion 301 of arm and his only a necessary to loosen nut 14 slightly to separate shaft 16 from portion 302 of arm 30. A Wing nut may replace nut 14 for this purpose. The arm 30 is particularly, suitable when connected to a support which cannot be removed. It will be understood that each of the elements de" scribed above, or two or more together, may also find a useful application in other types of drawing mechanisms differing from the types described above.
While the invention has been illustrated and described as embodied in top roll supports for drawing mechanisms,
. it is not intended to be limited to the details shown, since various modifications and structural. changes may be made without departing in any way from the spirit of the present invention. a
'Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can'by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention and, therefore, such adaptations should and are intended.
