MIDDLINGS PURIPIBR.

UNITED STATES PATENT OFFICE FAUSTIN PRINZ, OF MILWAUKEE, VISCONSIN.
MlDDLlNGS-PURIFIER.
SPECIFICATION forming part of Letters Patent No. 375,194, dated December 20, 1887.
Serial No. 154,610. (No model.)
To a/ZZ whom t may concern:
Be it known that I, FAUsTIN PRINZ, a subject of the Emperor of Germany, residing at Milwaukee, in the county of Milwaukee and State of Visconsin, have invented certain new and useful Improvements in Middlings-Puriders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
Figure l is a longitudinal vertical section through a middlingspurier. Fig. 2 is a vertical cross-section through the same on the line x x of Fig. l. Fig. 3 is a cross-section through aboltingframe, showing my invention applied Fig. 4 is a perspective view of a piece of a bolting-cloth with myinvention applied thereto. l
My invention has for its object to provide means to clear the meshes of bolting-cloth; and to such ends the invention consists in the construction and the combinations of parts, hereinafter particularly described7 and then specifically defined by the claims.
In the drawings, the letter A designates a middlingsvpuriiier casing of ordinary construction provided with a fan, B, in its upper part for creating a current of air through the side openings, C, and thence upward through the shaking frameD into the fan-box, from whence it escapes, as usual. The fan is rotated by belting connected to the pulley E, and the shaker-frame is suspended in the ordinary way by straps F and is reciprocated by a rod, G,
having an eccentric connection with a shaft at the end of the casing, the eccentric and shaft not being shown, and in the lower part ofthe casing is a screw-conveyer, H, of ordinary construction for carrying off the middlings.
I have illustrated but a single conveyer and a single shal'rer-frame, although there may be a series of both, as commonly practiced, as my invention is j ust as applicable where there are many as where there is only one shaker-frame used. Heretofore, when knockers have been used to strike the cloth to jar the same, the stroke has been s-uch as to force the cloth out from the parallel plane of its surface.
In order to give a movement in the direction of lr-hc plane of the cloth and obtain better re- .with any part of the shakerirame.
suits, I attach a plate or strip ofwood or other suitable material to the cloth disconnected from any rigidpart of the shaker-frame, which strip or plate is jarred or moved by a knocker operated by the reciprocation or movement of the frame, so as to jar the cloth in the direction of the plane of its surface, as distinguished from jarring it at an angle to the plane of the cloth, and thereby disengage the particles clogging the mesh and dislodge the same by the draft of air passing through the meshes.
In the drawings I have illustrated a strip, I, secured to the bolting-cloth J bynails or other means, with its ends free from rigid connection To this strip there is screwed or otherwise secured a bracket or arm, K, on which slides a horizontal block, L, of metal, wood, leather, rubber, or other suitable material. On the same arm on opposite sides of said block are stops or checks M to limit the throw of the block. One of these stops maybe rigidly xed to the arm, while the other may be adjustable thereon by means of a set-screw, a, so as to lengthen or shorten the throw of the block. In the reciprocation of the shaker-frame the said block will be thrown or slid back and forth on its arms, so as to strike the stops or checks M in alternation, and thereby push or move the strip I in the direction ofthe plane ofthe cloth, and the strip will jar the cloth in the same direction, i A
so as to open the meshes of the cloth, and thus, assisted by the air passing through the cloth, dislodge the particles which tend to clog the meshes. This construction not only jars the cloth in a line parallel with the plane of the cloth, but also acts more directly on the cloth and covers and operates on a larger area and more effectively clears the meshes of the cloth.
A single strip and single knocker are shown; but it is obvious that a number of them may be used running parallel with each other or arranged end to end, and instead of placing the strip lengthwise of the shaker frame, which, however, is the preferable way, it may be placed in any other relation to the length IOO divided by a central strengthening-partition,b, as illustrated in Fig. 3, there will be one of the knockers secured to each section of the cloth on opposite sides of said partition.
The shaker-frame is provided with the usual cross rods or strips, d, and the cloth with the usual strengthening or attaching strips, e. To deaden the noise of the knockers, the blocks may be cushioned with leather or other sounddeadening material.
In operation the shaker-frame D is moved in the usual way, and in its reciprocation the cloth is jarred in the direction of its plane by the knockers acting as described, so as to open its meshes, and air is drawn through the side openings, G, and up through the meshes of the cloth and out through the fanbox in the upper part of the casing A. i
The meshes of the cloth are thus more effectually cleared than heretofore and the middlings more thoroughly puriiied.
I have illustrated my invention as applied to a middlings-purier; but I do not mean thereby to restrict it to any particular form, as it may be applied to any bolting-cloth, whether of fabric or metal, and where the action is such as to cause the said knockers to strike and jar the cloth, as described.
Having described myinvention and set forth its merits, what I claim is- 1. The combination, with a bolting-cloth, of an arched arm connected with the cloth to move therewith and extended horizontally, and a block sliding on said arm and adapted to jar the cloth in a plane parallel with its surface7 substantially as described.
2. A middlings-puriiier comprising the following elcments: a casing provided with airinlet openings below a shaker-frame, a shaker`- frame above said openings and having the bolting-cloth secured thereto, afan to createa draft of air through the bolting-cloth, an arched arm connected to the cloth to move therewith and extended horizontally, and a block sliding on said arm and adapted to jar the cloth in a plane parallel with its surface, substantially as described.
In testimony whereof l aflx my signature in presence of two Witnesses.
FAUSTIN PRINZ.
