PAPER STOCK DRAINER.

PAPER-STOCK DRAINER.
SPECIFICATION forming part of Letters Patent No. 318,180, dated May 19,1885.
Application filed April 17, 1885. (No model.)
To all whom it may concern:
Be it known that I, WATSON GRAY, of Three Rivers, in the county of St. Joseph and State of Michigan, have invented certain Improvements in Paper-Stock Drainers, of which the following is a specification, reference being had to the accompanying drawings.
My improvements relate to improved paper-stock drainers of the kind for which I recently applied for patent, my application being numbered 142,924, and dated September 12 1884, which application has been allowed,) consisting of two layers of wooden slats a little separated from each other at their 15 edges, so as to leave spaces between them, and having inclosed between the layers-that is to say, within the space between the two series of slats*a body of gravel, broken stone, or the like suitable straining material, so that 2O the water in the pulp or paper-stock in a receptacle will pass down between the edges of the upper layer of slats, then through the body of gravel or the like, and then out between the edges of the lower layer of slats. This kind of stock-drainer has material and important advantages in practice over those heretofore used, as set forth somewhat in my said application; but I have found that there is a special advantage of much practical consequence in the peculiar construction which constitutes my present invention, which I will now describe in detail. In my said applica tion the wooden slats making the upper layers and those making the lower layers are placed at right angles to each other. Now,
while such a structure has manifest advantages in practice, it lacks one important quality in large measure, which I have secured perfectly by my present device by simply secur- 4o ing my upper and lower layers of slats in place on the frame parallel to each otherthat is to say, the upper ones directly over the under ones, so that the upper spaces between the edges of the slats are directly over those between the edges of the lower slats. The result is that the drainer can be used one side up to drain for a while, and theV accumulations of stock or fiber and refuse matter will all be in the gravel directly opposite and between the upper and lower spaces between 5c the edges of the two layers or slats. When it accumulates, as it will in time, so as to partially obstruct the working of the drainer, and it becomes desirable to clean it, all that is necessary is to reverse the drainer-that is, to turn it over and continue it in use, and it will promptly be perfectly cleaned and freed of accumulations by the action of the water draining out of the stock. This of course cannot be the case to a suiiicient extent in my 6o said drainer, in which the layers of slats are at right angles to each other.
My present device has all the advantages of the former, with the important addition of being self-cleaning in use, owing to the dierent construction.
In the drawings, Figure l is a plan View, and Fig. 2 an end view, of my improved device.
Referring to the letters upon the drawings, 7o A indicates the frame of the drainer, B, the upper series of slats separated by suitable small spaces; and C, the lower series of slats parallel with and directly under the upper series, so that the spaces D and E between the 7 edges of the two series of slats are coincident, or nearly so.
Having thus described my improvement, what I claim as new, and desire to secure by Letters Patent of the United States, is-
As an improvement in paperstock draining, a drainer for the bottom of a paper-stock receptacle composed of a frame, an upper and lower series of slats parallel to each other, so that the spaces between the edges of the slats are about coincident, and a body of straining material inclosed in the space between the two series of slats, substantially as set forth.
In testimony whereof I have hereunto subscribed my name.
WATSON GRAY.
