av firToRNEY United States Patent O 3,498,549 END PLATE FOR INK MILL Robert W. Saner, St. Louis, Mo., assignor to Centenary Central, Inc., St. Louis, Mo., a corporation of Missouri Filed Aug. 18, 1967, Ser. No. 661,561 Int. Cl. B02c 4/08, 4/28 U.S. Cl. 241-226 2 Claims ABSTRACT OF THE DISCLOSURE An end plate for roll type grinding mills, as ink mills, and the like, comprising a main metal body to which is secured, preferably removably, a tip of polyurethane, and the like.
BACKGROUND OF THE INVENTION Field of the invention The present invention relates generally to grinding mills, and more particularly to a novel end plate for ink mills and the like.
Description of the prior art Simple ink mills, and the like, include a container, adjacent rolls for grinding, and removable end plates which keep the ink or other material being ground from working otf the ends of the rolls. Heretofore, these plates have been made of a solid piece of metal. The tip which fits down between the rolls is readily chipped and broken with the result that the plate must be replaced or the ink will not 'be properly ground due to leakage at the ends of the rolls through the chipped or broken part of the end plate. Expensive downtime often results when an end plate is damaged and a replacement plate is not mmediately available. There results the expense of plate replacement. Hence, there has long been the need for an end plate for such mills to obviate the foregoing problems.
SUMMARY OF THE INVENTION In brief, the present novel end plate forl grinding mills comprises a main metal body and a replaceable tip plate including a metal base to which is bonded a polyurethane tip. The tip plate is bolted or otherwise secured to the main plate. The tip plate may be wholly of polyurethane, and the like, incorporating mounting ferrules, or the like.
Therefore, an object of the present invention is to provide a novel end plate for grinding mills, as ink mills, which fulfills the long existing need for an eflicient item; which reduces the costs of end plate replacement and substantially elimnates downtime; which incorporates a nonchippable or non-breakable tip and is of a material snugly engaging the ink mill rolls; and which otherwise fufills the objects and advantages sought therefor.
The foregoing and other objects and advantages are apparent from the following description taken with the accompanying drawings.
BRIEF DESCRIPTION OF T'HE DRAWINGS FIGURE 1 is an inner side view of an ink mill end plate incorporating the teachings of the present invention;
FIGURE 2 is an end view thereof;
FIGURE 3 is a cross-sectional view taken on substantially the line 3-3 of FIGURE 1;
3,498549 Patented Mar. 3, 1970 ICC DESCRIPTION OF PREFERRED EMBODIMENTS Referring to the drawings more particularly by reference numerals and specifically considering FIGURES l-5, 10 indicates generally an ink mill end plate incorporating the teachings of the present invention. The end plate 10 includes a main body 12 of metal, and the like, and a tip unit 14. The tip unit 14 includes a metal strip 16 and a polyurethane tip 18 of greater thickness which is bonded to the strip 16 by known methods, as by applying the polyurethane in a liquid state to the strip 16 in a mold. The main body 12 includes a reduced lower lip or seat 20. having threaded apertures therethrough. The lip 20 receives the upwardly extending strip 16, bolts 22, or the like, securing the parts fir-rnly together. The ends or edges of the tip unit 14 and the curved portions of the bottom edge of the main body 12 are on substantially the radius of ink rolls 23 with which the end plate 10 is employed.
In FIGURES 4 and 5, the end plate 10 is illustrated in operative position on the adjacent ink mill rolls 23. It will be understood that means are provided `for holding the end plates 10 in position and for removing and turning them as for roll and plate cleaning, plate placement, and the like, but such structure forms no part of the present invention, hence, has been omitted as nonessential to the present disclosure.
In FIGURES 6 and 7 is shown a modified end plate 10' having a main body 12' and a tip unit 14'. The tip unit '14' is wholly of polyurethane and includes flanged ferrules 24 which receive the bolts 22' secured in threaded openings in the lip 20'. The ferrules 24 may be flanged, as shown, or simply annular.
The polyurethane material employed in the tip 18 and the tip unit 14' is strong, flexible and resilient, thereby obviating fracture and breakage. It is exceedingly long wearing, renders eflicient service indefinitely, and resists deterioration from Cleaning materials. The invention has been descri'bed in connection with an ink mill, but it is applicable to other mills requiring such end plates.
It is thus apparent that there has been provided a novel end plate for ink mill rolls, and the like, which fulfills the objects and advantages sought therefor.
It is to be understood that the foregoing description and the accompanying drawings have been given by way of illustration and example. It is also to be understood that changes in form of the elements, rearrangement of parts, and substitution of equivalent elements, which will be obvious to those skilled in the arts, are contemplated as Within the scope of the present invention which is limited only by the claims which follow.
What is claimed is:
