PAUL H. GRIMM, OF GLEN COVE, NEYV YORK, ASSIGNOR TO THE GLEN COVE MANUFACTURING COMPANY, Ol? SAME PLACE.
CYLINDER FOR SEPARATING LIQUIDS FROM SOLIDS BY PRESSURE.
SPECIFICATION forming part of Letters Patent No. 358,974, dated March 8, 1887.
Applicalion filed November 1, 1886. Serial No. 217,760. (No modehl To all whom, it may concern.-
Be it known that LPAUL H. GRIMM, of Glen Cove, in the county of Queens and State of New York, have invented a new and useful Improvementin Cylinders for Separating Liquids from Solids by Pressure, of which the following is a specification.
In my United States Letters Patent No. 296,000, dated April 1, 1884, there is shown and described a machine for separating the solid andliquid portions of starch rcfusc,which comprises pairs of rollers between which the coarse refuse, saturated with water, passes, and by the action of which a large percentage of the water is expressed from the coarse refuse. In such a machine one roller has a plain rubber-covered or other suitably-constructed surface, while the other or bottom roller has its surface so constructed as to afford a free avenue of escape for water which is pressed out of the refuse. In that machine the lower roller was provided with channels or gutters upon its periphery,and had a covering of wirecloth or other foraminous material, which permitted the free passage of water through it into the gutters or channels, whereby the water was conducted to the ends of the roll. \Vhere the wire-cloth or other coveringis continuous throughout the periphery of such cylinder or roll, any rupture of the cloth at one point is with difficulty repaired without renewing the entire covering.
The objects of my invention are to provide a cylinder for the purpose above described, in which ready provision is afforded for renewing any portion of the cylinder which may be broken, and also for renewing any portion of the foraminous covering which may become ruptured or otherwise injured.
Although the cylinder which forms the subject of my present invention is intended more particularly for separating water from the coarse refuse of starch and ghrcose manufacture, it may be used in other manufactures for separating liquids from solids bypressure; and it will be understood that the cylinder which forms the subject of my present invention is to be employed in connection with a companion cylinder or roll, as describedin my aforesaid patent.
According to my present invention I concylinder.
strnctthe cylinder of two heads or end frames,
and perforated staves extending lengthwise of the cylinder and secured to the heads or end frames, and having their outer surfaces arcshaped in transverse section; and I make the foraminous covering of wire-cloth, perforated metal, or other analogous material, which is applied to the outer surfaces of the staves,and forms the exterior surface of the cylinder in sections which correspond to the staves of the By this construction I provide for readily renewing any stave of the cylinder or any one of the sections of covering. The covering may be advantageously secured by cut ting it slightly wider than the staves and then folding or turning the longitudinal edges ofthe coveiingsections inward upon the edges of the staves, so that the edge portions of the coverin g-sections will be securedbetwcen the staves. In order to afford a free avenue of escape for the water which may pass through the covering, I flute or channel the staves lengthwise, or otherwise construct them with irregular exterior surfaces, and the staves may have on opposite longitudinal edges inwardly-extending flanges for strengthening them, and they may have at their ends pockets adapted to receive the nuts for bolts which pass through the rims of the heads and serve to secure the staves thereto.
In order to provide for the ready escape from the cylinder of water or other liquid which pours through the perforated periphery, I construct, by means of suitable boards or plates, conductors, which receive the water passing through the periphery of the cylinder and deliver it at the ends of the cylinder. These conductors I form by side boards or plates, which are secured tothe opposite sides of the radial arms in the two heads, and which extend lengthwise of the cylinder, and the bottoms of these conductors are formed by boards which extend between the two side boards or plates secured to adjacent arms. These bottom boards are preferably of wedge shape, and are inclined from about the middle of the length of the cylinderin opposite directions relatively to the axis of the cylinder.
The invention will be hereinafter more fully described, and pointed out in the claims.
In Figure l of the accompanying drawings I have represented in end view and transverse section a cylinder embodying my invention. Fig. 2 is a longitudinal section of the cylinder. Fig. 3 isaface view of one of the staves thereof, and Fig. 4 is a transverse section of one of the staves with its foraminous coveringsection applied thereto.
Similar letters of reference designate corresponding partsin all the figures.
A designates the shaft, which at the ends may have journal portions A; and B designates two heads or end frames, which may be of cast metal, and which are arranged at suita ble distances apart upon the shaft A. These heads or end frames, B, may be secured firmly to the shaft by means of keys I), or otherwise. Each head comprises a hub or center, b,'a circular rim, If, which may be L-shaped or angular in transverse section, as shown in Fig. 2, and radial arms b connecting the hub and rim.
For a purpose hereinafter described the heads or end frames, 13, should be secured upon the shaft in such relative positions that their arms Z) shall lie in the same planes. The periphery of the cylinder is composed of staves C, which are segmental in their transverse section, as best shown in Fig. 1, and which may be of cast metal. The staves may have at opposite longitudinal edges inwardly-extending ribs 0, for giving them the desired strength, and at the outer ends they may be constructed with inward slots or pockets 0, to receive the nuts (1 of bolts d, whereby said staves are sccured to the rims b of the heads B. The nuts d may be slipped inward from the ends of the staves and the bolts inserted outward through the rims b and turned into the nuts, which may be held by a suitable wrench. In this way I provide for properly securing the staves G to the heads B, and at the same time leave the entire length of the stave uniform and unbroken upon its outer surface, so that the whole length of the stave will be effective for pressing. Throughout its surface each stave is formed with numerous small holes or perforations 0 These holesor perforations may be formed in the staves by casting or drilling, and they may be, for example, about one quar' ter (4 of an inch in diameter at the outer surface of the stave, and they may flare inward and be of considerably larger diameter at the inner surface of the stave. This taper form of the perforations a greatly facilitates casting them properly, and it also prevents their clogging by any material which may pass through the foraminous covering and enter their outer ends.
The cylinder has a covering, D, which is not continuous throughout the periphery thereof, but is made in sections corresponding to the staves 0, each stave having a separate section of foraminous covering. This covering D may consist of wire-cloth, as shown at the right-hand portion of Fig. 3, or of very finely perforated sheet metal, as shown at the lefthand portion of Fig. 3; or it may consist of any finely-perforated, reticulated, or foraminous material suitable for the purpose.
The covering-sections D may be cut somewhat wider than the staves O, and the longitudinal edge portions of the covering-sections D may be lapped or folded inward upon the sides of the staves, as shown at d in Fig. 4. The turned-in edges of the covering-sections D will then be secured between the staves and the covering-sections will not need other means to hold them in place. The particles of solid matter will in the first useof the cylinder wedge in between the staves C so as to entirely fill the cracks or crevices between the staves, and therefore will not only prevent the passage of further solid matter through these crevices, but will also aid in holding the coveringsections tightly upon the staves.
To facilitate the escape of water or other liquid which passes through the covering D,
the outer surfaces of the staves should be of irregular construction, and, as shown, the staves are fluted, grooved, or channeled on their outer surfaces from end to end.
hen any portion of the covering D becomes ruptured, or when any stave becomes broken by the passage through the machine of stones or fragments of iron, it is only neces sary to renew such covering-section D or such stave in order to make the cylinder perfect.
To provide for the ready escape from the interior of the cylinder of water which may pass. through its periphery, I form in the cylinder, and between adjacent arms, conductors E, which' deliver the water or other liquid to the opposite ends of the cylinder. As here represented, the arms I) are flat at the sides, and E designates side boards or plates, which are placed against the flat sides of the arms, as shown in Fig. 1, and whichv extend from end to end of the cylinder, or rather from the inner side of the rim Z) of one head to the inner side of the rim of the other head. These boards or plates may be secured in place by means of bolts e, inserted through them, and
the arms If, as shown in Figs. 1 and 2.
E designates bottom boards or plates, which close the spaces between the side boards or plates, E, and which are here shown as in clined from about the middle of the length of the cylinder in opposite directions, toward and relatively to the axis of the cylinder. At their inner ends the bottom boards, E, are near the outer edges of the side boards, E,and from their point of meeting they pitch or incline in opposite directions toward the ends of the cylinder, so that liquid drained into the cylinder through the periphery will flow readily toward the ends and be delivered from the cylinder without crossing the diameter.
In order to close the spaces between the boards or plates E, which are applied to the opposite sides of each arm I), I may lay and secure between them a strip of wood, e, as best shown in Fig. 1, so that water cannot pour downward between the two parallel boards E, which are applied to each arm,
It will be obvious that the arms I) in the two heads B should lie in the same planes, so that the straight boards or plates E may lie against their opposite sides.
\Vhat I claim as my invention, and desire to secure by Letters Patent, is
