PORATION OF NEW JERSEY.
HIGH BRIDGE, NEW.J'ERSEY, A COR- MEANS FOR STOCK.
a imatio flledoctober 1, 1923. 'Serial no. 665,982.
To all whom itmay concern,"
Beit known that I, LESHER W. VAN BUSKIRK, a citizen of the United States, residing at High Bridge, in the county of Y Hunterdon-and State of New Jersey, have invented certain new I and useful Improvements in Means for Refining Pa er Stock, of which the following is a speci cation.
In pulp refining .engines of the .Jordan type, a rotatable cone, commonly called a plug, with straight blades or knives, cooperates with a fixed shell, commonly called a liner, with more or less angularly disposed blades. The motive of the latter'arrangement is to retard the progress of the pulp material. Pulp materials vary, however, and while some materials are retarded even to the extent of being burnedunder the frictional heat developed, other materials are afforded an uninterrupted passage through the engine without having been acted upon by the blades. In any event, the results are indifferent and the action of the plug and liner is unmistakably a hit or miss grinding action. I
I have discovered, that, by causing the stock or pulp material to dwell with more or less frequent periodicity with respect to its passage through the engine andby cans} ing it to be coincidently shunted to and fro with respect to'the plug and liner, I obtain a drawing action instead of the usual inding action with the result that the yield is characterized by an abundance of long fibers. I v
My invention consists in certain details of construction of the plug and liner and 'in the assemblage of said elements to secure the results stated, all as hereinafter more particularly described and finally claimed.
' In the accompanying drawings, forming a part hereof, I I
Figure 1 is a lon 'tudinal sectional view of mated plug and hner elements embodying my improvements.
Fig. 2 is a fragmentary lan view showing a development of the p u blades.
Fig. 3 is a similar view s owing a development of the liner blades; and
Fig. 4 is a sectional detail of the dam or diverter construction.
In practicing the invention, I so construct and arrange the plug and liner that the stock or pulp material being acted upon iscaused disposed tional to dwell at frequent intervals and .to I be shunted repeatedly back and forth with relation to the plug and liner. The dwells are established by bridging alternate blades of the plug at points opposite one another and in proximity with and preferably slightly in advance of right angle. extensions of the liner blades.
The plug is represented generally by the I numeral 5, and the liner by the numeral 6. Each of said elements, inclusive of the knives or blades, is preferably an inte ral construetion of manganese steeltoug ened by. ap-
propriate heat treatment and quenching.
They might, however, be constructed of other steel, or even'of cast iron, or one of said elements may be constructed of manganese steel 'and theother element of ordi- .sets of blades 7, as indicated at 8 and9-which represent web formations, of the height ofv the blades. As illustrated in Fig. alone of the end walls is almost perpendicular and the other is of sloping contour.
The blades 10 of the liner may have the usual except that the steps are joined by right v angle extensions 12.' The latter are opposite the dwells or deflectin nary steelor cast iron; but the best results I usual step zigzag or obtuse angleformation, 38 indicated at 11, and may otherwise be as elements 0 the plug. The purpose and e feet of this construction and arran ement is to cause the stock or pulp material to re peatedly change its course by alternately shunting it back and forthwith relation to the plu and liner. It follows that the action 0% the blades on the stock is a' drawing action rather than a rinding action with the result that there is a remarkable yield of long fibers andthe product is uniformly. superior-to products of the convenpractice regardless ofthe nature of the st k.
The lug has openings 13 and 14 for the usual s a (not shown) the openings 13 being established by an integral hub :15 which together with-its spokes 16.is re-inforced by endwiseranging -webs 17. Since the plug is preferably a casting of, manganese steel and'unmachineable the spokes 16 have inserted fillings 18 of machineable claim v prisin steel p ug and liner elements of the integral alternate sets of blades bridged by transverse -webs substantially the height of the blades.
1. Means for refining pulp material, com- ,the combination with mated alloy construction type, of provisions .for establishing high frequency dwells in the passage of the stock and including bridging members between alternate blades of, the
lug, and means on the liner and co-op'eratmg with said bridging members. for. diverting the stock from one element to the other.
2. In a Jordan engine, the combination I of bladed plug and liner elements, the blades of one of said elements having offset or angle formations, and adjacent blades of the other element having connecting Webs or bridges which co-operate with the angle formations to divert the stock from one element to the other.
3. A plug for a Jordan engine having 4. A plug for a Jordan engine having dams or bridging elements instaggered-relation and whereof one end wall is substan-' tially perpendicular and whereof the other end wall is of sloping contour.
In testimony whereof I aflix my signature.
