IMPROVEMENT lN PEAT-WRINGERS.

Specification forming part of Letters VPatent No. 117,591, dated August l, 1871.

To all whom t may conce-ru.-

Be it known that I, AIME NIcHoLAs NAP@ LEON AUBIN, of Portland, in the county of Middlesex, in the State of Connecticut, have invented an apparatus for extracting a certain portion of the water retained in peat when recently drawn from the bog, and which I call a Peat-ringer,77 of which the following is a specication.

The nature of my invention consists in forcing the wet peat to traverse a box provided with strainers of a particular construction, against which the peat is submitted to a gradually-increasing pressure, and so arranged that the peat, traveling in one direction, cannot escape through the apertures, while the water can run out in a contrary direction.

Figure l is a perspective View of the wringer. Fig. 2 is a side and top View of the strainers on a larger scale. Fig. 3 shows how the strainers are placed on the boards so 'as to be easily withdrawn and replaced. l

A A A A is an oblong cylindrical box made of wood or iron. The bottom of it is continued to a. On the top,near one end,is ahopper,B B, through which the peat is introduced. C C is a piston moving backward and forward. It is long enough to close the lower aperture ofthe hopper while the front end of the piston moves to a. The front end of the latter has holes covered witha wire-gauze, c1, to allow air to enter the box when the piston is moving backward. Above the forward face of the piston at c2 is iixed aknife with angular teeth. On the opposite side of the lower aperture of the hopper is a plate of iron or steel, under and close to which the piston passes. This knife and Vplate are placed thus in order to cut any root which otherwise might interfere with the motion of the piston. Any fine roots adhering to the knife are thrown off when the piston recedes and passes the lower edge ofthe hopper. D D is a door, which, when lowered to its place, forms a continuation of the upper side ofthe box to which it is hinged. d' is a hook by which the door is fastened when the apparatus is in operation. This door enables the attendants to clean the strainers and the inside of the box. E, upright partition, furnished on each side with strainers, and placed there to divide the peat which is forced through the box, and thus to multiply the water-separatin g surface. F F, compressors. They are composed of two boards, hinged to each of the upright sides of the box at f1 f1. Their inside surface is furnished with strainers. O11 the outside are fixed two iron straps, f2 f2, withan eye at their outward end to receive a rope or chain. Each rope passes over a pulley placed on an upright fixed to the edge of the bottom opposite each compressor. A weight, f3 f3, is suspended to each of the ends passing over the pulleys f4f4. Theseuprights areproportionedto the pressure to which the wet peat is to be subinitted, and tend to draw the compressors together and toward the center partition E. G G, strainers. They are composed of a frame, g1, made of flat iron, to which strips of sheet-tin or galvanized iron g2 g2 are riveted, so as to overlap each other like blinds, leaving a narrow space between the strips. Each of these strainers is placed in a recessleft in the boards, as seen at Fig. 3, and kept in its place by a thin strip ofwood or metal. These strainers can thus be easily withdrawn'and replaced. The strainers, which do not move, are placed over holes bored in the bottom of the box for the escape of the water. The water absorbed by the strainers on the compressors passes under the scalloped apertures f5 f5 left attheirlower edge. The water from all the strainers is conducted to a receiver placed under the box.

The wrin ger being constructed as just described, its operation is as follows: The peat, as dug from the bog, is thrown into the hopper B, and when the piston has moved back to the position shown in the drawing it falls into the box; then a forward stroke of the piston pushes it toward the compressors to al. Another stroke brings a new charge, which, when moved forward, pushes the former one between the compressors, where the space becoming gradually contracted, the ,wet peat is slowly pressed against the strainers. As the peat travels in the direction of the overlap of the strips its ibrous form prevents it from escaping backward through the spaces between the strips while the mass is moving forward. In

the mean time, the water expressed from the mass by the pressure to which it is exposed runs out freely through the strainers. As may be seen,

the compression is constantly proportionate to the weights, and regulates itself according to the quantity of material brought by each stroke of tliepiston. The operation of the wringeris, there fore, regular, continuous, and selfadjusting, as each motion of the piston expels a quantity of peat, partially deprived of its Water, equal to the a hopper, B, piston C, compressors F, and strainamount received through the hopper, and which ers G, the Whole constructed and operatingsubhas to be exposed in its turn to the same pressstantially as set forth. Y ure due to the Weights. N. AUBIN.

What I claim as my invention is- An apparatus to separate from freshly-dug peat Witnesses: a portion of its Water, and which I call a peat- N. SLINGLAND, Wringer, consisting in a box or cylinder, A, with J. SCOUGHAM QUIN.
