4 Claims.
This invention relates to a feed roll mounting for a fiber carding machine and more particularly to a mounting which substitutes spring pressure for the weights presently used to apply pressure to the feed roll.
It is among the objects of the invention to provide an improved feed roll mounting which can be substituted for the existing feed roll mounting in a fiber carding machin with no material modification of the machine construction; which provides movable bearings for the arbors at the ends of the feed roll to permit movement of the feed roll toward and away from the associated feed plate and supports the feed roll against movement along the feed plate and the bearings against rotation; which provides adjustable compression springs resiliently urging the feed roll toward the feed plate; which does not interfere in any way with the operation of the feed roll; and which is simple and durable in construction, economical to manufacture and easy to install, and positive and effective in operation.
Other objects and advantages will become apparent from a consideration of the following description and the appended claims in conjunction with the accompanying drawing wherein:
Figure 1 is a somewhat diagrammatic side elevational view of a fragmentary portion of a fiber carding machine showing a feed roll mounting illustrative of the invention operatively applied to the machine;
Figure 2 is a fragmentary cross sectional view on an enlarged scale on the line 2-2 of Figure 1;
Figure 3 is a cross sectional view on theline 33 of Figure 2; and
Figure 4 is a rear elevational view of a bracket constituting an operative component of the feed roll mounting.
With continued reference to the drawing, the numeral generally indicates the frame of a carding machine and the numeral l I designates a feed plate mounted on and extending transversely of the frame and provided with a beveled discharge end I2 having an upwardly projecting tapered lip I3. A feed roll I4 extends transversely of the frame It! and is disposed above the feed plate II and adjacent the lip I3 at the discharge edge of the feed plate. A lickerin roll or cylinder I5 is disposed within and extends transversely of the frame adjacent the discharge edge I2 of the feed plate I I and this lickerin cylinder has a coaxial shaft I6 supported in bearings, as indicated at I1, mounted on the frame ID. A cover I8 extends from a location adjacent the lip I3 of the feed plate over the upper portion 2 of the lickerin cylinder and a carding cylinder I9 extends transversely of and is journaled on the frame adjacent the side of the lickerin cylinder I5 remote from the feed plate I I.
As fiber carding machines are well known to the art, the above brief description and the fragmentary illustration of the machine as shown in Figure 1 is considered sufiicient for the purposes of the present disclosure.
The fiber lap is carried on a supporting shaft or beam spaced from the side of the feed roll I4 remote from the lickerin cylinder I5 and this lap is fed under the feed roll, that is, between the feed roll l4 and the feed plate II to the lickerin cylinder from which it is fed to the carding cylinder I9. The feed roll is driven by suitable means, such as link chains and chain sprockets, not illustrated, connected to the ends thereof and not only the speed of this cylinder but the pressure with which it bears on the lap disposedv between itself and the feed plate is important in controlling the feeding of the fiber to the carding cylinder.
The feed roll is provided with coaxial arbors of reduced diameter projecting one from each end thereof, one such arbor being shown in the accompanying drawing and designated at 20. A bearing sleeve 2| of cylindrical shape has a coaxial bore 22 extending therethrough and r0- tatably receives the arbor 20. There is, of course, a similar bearing sleeve receiving the arbor at the other end of the feed roll.
In the present construction of carding machines the bearing 2| is mounted in a bracket and subjected to the force of a weighted lever which exerts downward pressure on the feed roll toward the feed plate II. Such a weighted lever tends to exert a substantially constant downward force on the feed roll or even a, diminishing force as the feed roll is raised upwardly away from the feed plate. It has been found that this arrangement is not only expensive and cumbersome but that better results are obtained by exerting an increasing downward force on the feed roll as the latter is moved upwardly away from the feed plate.
The present invention provides brackets disposed one at each end of the feed roll and one of which is illustrated in the accompanying drawing and generally indicated at 25. This bracket is of elongated, rectangular cross sectional shape and includes a first leg 26 and a second leg 21 joined at one end to the leg 26 and projecting substantially perpendicularly from the latter at one end thereof. The leg 26 is materially longer 3 than the leg 21 and at its end remote from the leg 21 it overlaps the beveled discharge edge l2 of the feed plate II and is provided in its portion overlapping the edge of the feed plate with transversely spaced apart apertures 28 and 29. Stud bolts 3|] extend one through each of the apertures 28 and 29 in the bracket and are threaded into tapped recesses in the feed plate to rigidly secure the bracket to the feed plate at the correspond ing end of the latter with the leg 26 of the bracket upstanding from the feed plate. The lower portion of the leg 26 is inclined relative to the upper portion, as is clearly illustrated in Figure 3, so that, while the lower portion of this leg has a flat surface in contact with the edge surface of the feed plate, the upper portion of the leg has its front and rear surfaces substantially perpendicular to the plane of the top surface of the feed plate and the leg 21 is disposed above the feed plate and substantially parallel to the latter.
The bearing 2| has a flattened side 3| which bears against the front surface of the inclined lower portion of the bracket leg 26, that is, the surface of the bracket leg adjacent the feed plate II and the engagement of the flattened surface of the bearing with the flattened adjacent surface of the bracket leg at the corresponding ends of the feed roll guide the bearing 2| in its movements toward and away from the feed plate II and also maintain the bearing against rotation with the corresponding arbor 20 of the feed roll in case there should be any frictional resistance to rotation of the arbor in the bearing sleeve.
The leg 21 of the bracket 25 is provided with a substantially centrally disposed tapped hole 32 and the bearing sleeve 2| is provided with a rounded recess 33 substantially in Vertical alignment with the tapped hole 32. A stud 34 is threaded through the tapped hole 32 and held in adjusted position relative to the bracket leg 21 by a lock nut 35 threaded onto the stud at the top side of the bracket leg 21 and a spring seat or abutment 36 is seated in the recess 33 in the bearing sleeve 2|. An upper spring seat or abutment 31 is seated on the lower end of the stud 34 which is the end of this stud nearest the bearing sleeve 2| and a coiled compression spring 38 is compressed between the upper and lower spring abutments 31 and 36 and exerts a downward pressure on the bearing sleeve 2| and on the corresponding end of the feed roll I4 toward the top surface of the feed plate A lubricant hole 39 extends through the lower spring abutment 36 and the portion of the bearing sleeve 2| between the recess 33 and the arbor 20 and the lower abutment 36 is formed in its upper side to provide a cup 4|] for holding a suitable bearing lubricant, such as lubricating oil.
The end mounting illustrated in the accompanying drawing and described above is duplicated at the other end of the feed roll so that both ends of the feed roll are supported in place and resiliently urged toward the upper surface of the feed plate II. The direction of rotation of the feed roll and its feeding action on the fiber lap between itself and the feed plate H is such as to maintain the bearing sleeve pressed firmly against the adjacent sides of the corresponding bracket so that there is no tendency for the feed roll to move longitudinally of the feed plate.
While the compression springs will tend to increase the pressure on the feed roll as it moves further away from the associated feed plate, the rate of these springs and the force exerted thereby can be selected to provide the most effective 4 pressure on the feed roll for the proper feeding of the lap to the lickerin and carding cylinders.
The mountings of the present invention can be substituted for the feed roll mountings present on an existing carding machine with no material modification of the machine construction and provide a more solid mounting for the feed roll with better control of the feed roll pressure. It is to be noted that the downward pressure exerted on the feed roll by the springs can be adjusted by threading the studs 34 in the proper direction through the tapped holes in the corresponding upper bracket legs.
The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiment is, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims, are, therefore intended to be embraced therein.
