JAMES A. OROOKER, OF BOSTON, MASSACHUSETTS.
AUTOMATICALLY-REVERSING FILTER.
SPECIFICATION forming part of Letters Patent No. 228,986, dated June 22, 1880.
Application filed April 15, 1880.
To all whom it may concern:
Be it known that I, JAMES A. ORooKER, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Automatically-Reversing Filter, of which the following is a specification.
The nature of my invention consists in combinin g, with a reversing case for holding filtering material, a piston which is driven in one direction by the action of the stream of water which is to be filtered, and in the other direction by the action of springs or by gravity; This piston is inclosed in the same outside cylinder that holds the revolving case in which the filtering material is contained, and operates on the revolving case through links or ratchets, the whole being so combined and arranged that the opening of the faucet will start a stream of water or other fluid directly onto the piston and cause it to move. The movement of the piston is communicated to the filter-case, and causes it to make a halfrevolution. As soon as the pressure is re moved-that is, when the water is cut off the piston returns to its place, leaving the filtercase unturned in its retreat, the piston acting on the filter-case when moving in one direction only.
The object of this device is to insure the frequent reversing of the filter-case, so that the filtering material will be kept always clean and the filth collected by the filter will be washed away every time the faucet is opened.
In the drawings, Figure 1 is an elevation of my invention, a part of the outside case being represented as broken away to show the internal construction. Fig. 2 is a vertical section of the same, the plan of section being at right angles to the representation in Fig. 1. Fig. 3 is a View, in elevation, showing the interior.
In the drawings, A represents the inclosingcylinder, in the lower point of which the revolvin g filter-case B rests. This filter-case is in form a true sphere, flatted at'four of its sides, as shown in Fig. 2; otherwise it is a perfect sphere, and will revolve as such on the seat K, which is carefully ground smooth and concave to fit it, and being provided with an elastic washer or packing, if desired. This case B has no axle to turn on, but is kept in (No model.)
its place by the seat K, the ring M, and the walls of the cylinder A.
H H, &c., are short studs or pins projecting from the flatted sides of the filter-case. (See Figs. 1 and 2.) This filter-case B contains the filtering material, and is provided with wire sieves or other foraminous diaphragms N N, Fig. 2, which serve to keep the filtering material in place and yet allow of the passage of the water or other fluid.
O is an annular piston arranged to work in the space between the partition P and the outer walls of the cylinder A. This piston is shown at its highest point in Fig. 1, at its lowest in Fig. 2, and at an intermediate point in Fig. 3.
The infiowing water through T and passage S S, as indicated bythe arrows in Fig. 2, will cause the piston O to descend. It is caused to ascend by springs, one of which is shown at B, Fig. 2.
The annular piston O has attached to it pivoted swinging links D, both of which are shown in Fig. 3. These swinging links D are notched, as indicated at E E E, Fig. 1.
When the piston is at its highest point, as seen in Fig. 1, the lower ends of the links D remain just over one of the studs H, so that as soon as the piston begins to descend the links D will push down onto the studs and action takes place as soon as the flow of water is stopped by turning the faucet. Thus the rising of the piston does not cause the filtercase B to revolve, the piston acting on the filter-case B in its downward motion only.
The notches on the links D (see Fig. l) have curved or inclined upper surfaces, so that when the links are drawn upward by the piston O the said links swing away (being,
pivoted at d) from the studs H H, and therefore have no action upon the filter'case B.
When the faucet is open the flow of water is as follows: It passes in through '1 and the passage S S S S, depressing the piston G to the position indicated in Fig. 2. Then the water has a free passage to the filter-case B, and through it to the outlet L.
If desirable, the annular piston O can be arranged to move upwardly by the pressure of the Water, and to turn the case B in its upward movement, the downward movement being caused by the gravity of the piston and its adjuncts.
Having thus described my invention, What I desire to secure by Letters Patent is- 1. In a filter, the combination of the revolv-' ing case B and the inclosing-eylinder A, pro- 15 vided with a seat, K, substantially as and for the purpose described.
