MICKAEL KOERPER AND EDGAR C. TALLEY, OF \VACO, TEXAS.-
MACHINE FOR FILTERING LIQUIDS.
SPECIFICATION forming part of Letters Patent No. 620,786, dated March '7, 1899.
Application filed June 2, 1898. Saris-1N0. 682,382.
To aZZ whom it may concern.-
Be it known that we, MICKAEL B. KOERPER and EDGAR O. TALLEY, of Waco, in the county of McLennan and State of Texas, have invented a new and Improved Machine for Filtering Liquids, of which the following is a full, clear, and exact description.
The object of our invention is to provide a machine for filtering oils and other liquids, so constructed that it will be simple and economic and wherein an endless filtering-belt will be employed and material be so delivered to the said belt as to materially promote cleansing of the belt.
A further object of the invention is to provide for the speedy and convenient separation of any foreign matter from the liquid without removing any portion of the machine and without necessitating the adjustment of parts of the machine, the filtered material being received and delivered at one part of the machine and the refuse matter discharged at another portion of the machine.
The invention consists in the novel construction and combination of the several parts, as will be herinafter fully set forth, and pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in'all the figures.
Figure 1 is a longitudinal vertical section through the machine. Fig. 2 is'an end View of the machine. Fig. 3 is a transverse section on the line 3 3 of Fig. 1; and Fig. 4 is a section taken substantially on the line 4 4 of Fig. 1, parts of theend rolls only being in section.
A casing A is provided, comprising, preferably, two closed sides connected at the top and at the bottom, the casing being open at its ends. Near the center of the casing a shaft 10 is transversely mounted, which shaft is fixed and carries two disks 11, one being located near each side of the casing, as shown particularly in Fig. 3. A tank B is located below the disks, the disks extending into the said tank, and the bottom of the tank tapers from its ends to a point near the center, the deepest portion of the tank being that which is below the disks, as shown in Fig. 1. An
opening 12 is made in a side of the tank at its (No model.)
deeper portion, and near the bottom the said opening is surrounded by an exit-tube 13, since the filtered material received by the said tank will pass out through the pipe 13. A roll 14 is located above one end of the tank B, the roll being secured upon a shaft 14, j ournaled in the sides of the casing. The roll 14 is provided, preferably, with a cover of a soft material. Above the roll 14 a second roll 15 is located, parallel with the roll 14. The roll 15 is shown larger than the roll 14 and is secured to a shaft 15, the shaft being mounted in boxes 16, held to slide in slots 17 made in the vertical members of the yoke 17, the yoke extending from side to side of the machine. A spring 18 is located upon each box 16, and each spring is attached to or has bearing against a follower 20, attached to a screw 19, one of the said screws being carried up through a yoke near each end thereof. By this means the upper roll 15, which is adapted to take up the refuse matter, is adjusted to and from the roll 14.
A small roll 21 is located below the roll 14, the said roll 21 being secured upon the shaft 21*, journaled in the sides of the casing. The roll 14 is, however, partially within and partially above the tank B, while the smaller roll 21 is below the tank, and usually between the two rolls 14 and 21 a pipe 22 is introduced into the casing adapted to supply steam or air for the purpose of cleaning the filtering material when the character of the liquid to be filtered is very sticky. A roll 23 is located between the disks 11 and the roll 14, the roll 23 being secured upon the shaft 23, mounted in the sides of the casing, and between the small roll 23 and the roll 14, which is the driving-roll, a trough 24 is horizontally located, adapted to receive any froth that may accumulate during filtration, since in the filtration of cotton-seed oil by our improved method the froth is very often present. This frothy matter finds an exit through a suitable outlet-opening 25 in a side of the casing, around which a pipe 26 is secured.
A small roll 27 is located below the tank 13, between the deeper portion of the tank and the end farthest removed from the drive-roll 14. The roll 27 is secured upon the shaft 27, and the said shaft is mounted in boxes 34, adj ustable by means of set-screws 35, which are passed out through the end portion of the easin g and terminate in suitable hand-wheels 36, as shown in Figs. 1 and 2.
Above the end of the tank near which the roll 27 is placed another roll 28 is transversely located, being secured to the shaft 28, which is journaled in the casing. The filtering material is in the formof an endless belt 0, and the said filtering material may be paper, silk, bolting-cloth, or the equivalent, and the endless belt is made to pass over the driving-roll 14, the roll 23, the rolls 21 and 27, and around the roll 28 to an engagement At with the lower portions of the disks 11. each side edge of the filtering-belt a double thickness of material 29 is secured, one portion of the material extending over the top and the other across the bottom of the belt, as shown best in Fig. 4, and a chainbelt 30 is secured to the inner face of the filteringbelt near its reinforced edges. The endless chain is adapted to engage with the teeth of sprocket-wheels 32, one of which wheels is secured upon the shaft of each of the rolls with the exception of the upper roll 15, the engagement of the chain belt with the sprocketwheels being best shown in Fig. 4.
The liquid to be filtered is delivered to'the upper surface of the filtering-belt between the disks 11 and near the roll 28, the delivery being made through the medium of a spout 33, having its lower or delivery end flaring or made so wide as to distribute the material transversely across the belt, thus spreading the material and promoting a quick filtration, and at the same time the impact of the liquid upon the belt will tend to clean the latter. By reinforcing the edges of the filtering-belt a tight and liquid-proof connection is effected between the said filtering-belt and the disks 11, the main portion of the filtering being accomplished between the disks. The refuse matter will be carried by the belt between the rolls 1% and 15, where the said material or matter will be compressed and flattened upon the discharge-roll 15, to be removed therefrom by a knife 38, whose cutting edge is brought quite close to the periphery of the roll 15, as shown in Fig. 1, and the material removed from the discharge-roll 15 will 'be' conducted from the casing through the medium of a chute 37 or a like device.
As heretofore stated, the device is exceedingly simple, durable, and economic, and no portion of the machine after the parts have been once adjusted need be disturbed when material is to be filtered, and the endless filtering-belt renders the act of filtration uninterrupted during the time that the drivingroll 14 is in action.
Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. In a machine for filtering liquids,an endless filtering-belt, roll-supports for the said belt, and disks arranged at opposite sides of the belt for depressing the same between sundry of the roll-supports, substantially as specified.
