NITED STATES PATENT OFFICE,
JAMES H. BLESSING, OF ALBANY, NEIV YORK.
COAGULANT-FEEDER.
SPECIFICATION forming part of Letters Patent No. 412,911, dated October 15, 1889. Application filed April 10, 1889. Serial No. 306,747. (No model.)
To all whom it may concern:
Be it known that I, JAMns I-I. BLEssINe, of the city and county of Albany, in the State of New York, have invented new and useful Improvements in Coagulating Devices for Water-Purifying Apparatus, of which the following is a specification.
My invention relates to improvements in devices for supplying liquid coagulants to Water before the latter enters a filtering apparatus; and it consists of an automatic valve which is operated by the watcr-current on its passage to the filtering apparatus, and by which a portion of the water-supply is diverted to supply a tank provided with a drip-pipe, from which the water is permitted to escape in avery gradual manner, and with an overflow-pipe for preventing the water from rising in said tank above an established water-line, said drip-pipe being arranged to discharge the water therefrom into an opentop float which is contained in a tank containing the liquid coagulant, so that by the gradual sinking of said float by reason of the accumulation of the water therein said coagulant will be forced to rise to the level of an outlet-pipe of the coagulant-tank, said outletpipe and the overflow-pipe of the water-tank first referred to herein being fitted to discharge into an induction-pipe of a force-pump, and by the operation of said pump the water diverted from the supply-pipe of the filtering apparatus and a charge of the liquid coagulant, which have been commingled, are forced back into said supply-pipe before the latter is joined to the filtering apparatus.
In the accompanying drawings,which are herein referred to and form part of this specification, Figure 1 is a side elevation, partly in vertical section, of an apparatus embodying my invention; and Fig. 2 is a plan view of said apparatus.
As represented in the drawings, A designates a filtering apparatus for purifying water. Said filter of itself forms no part of this invention, but may be of any preferred construction.
Bis the supply-pipe for conveying the water from the source of supply to the filtering apparatus, and O is the distributing-pipe for conveying the purified water from the filter ing apparatus to any point that may be required.
D is a valve-chamber, which constitutes part of the supply-pipe B, and which contains a valve E, that is held in open position duce a full opening movement of the valve F and a partial opening movement of the valve E will produce a corresponding opening movement of the valve F. The latter is fitted to govern a discharge-opening in the valve-casing D, and from said dischargeopening a discharge-pipe I leads to conduct a portion of the water from the supply-pipe into a small water-tank H. The dischargepipe I is provided with a valve J for regulating the outflow of water therefrom. The tank H is provided with a drip-pipe K and with an outlet-pipe L, the latter being fixed at a point where itis desirable to maintain the water-level in said tank. Said drip-pipe is provided with a valve M, by which the discharge of water through said pipe can be regulated as occasion. may require.
N is a coagulant-tank for containing a liquid coagulant. Said tank should be located under the discharge end of the drippipe K, and it is provided with an open-top float O, which is borne up by the liquid coagulant contained in said tank until the weight of said fioat and the water discharged therein by the drip-pipe K overcomes the ability of the coagulant to maintain said weight. The constant, if meager, discharge of water from the drip-pipe K into the float 0 produces a gradual sinking of the latter into the liquid coagulant and causes a displacement of said coagulant, so that a corresponding rise of its surface will be effected thereby, and to prevent such rising above an established level and to provide for utilizing said coagulant an out-spout P is provided for carrying off the displaced coagulant from said tank. Said spout is arranged to discharge the coagulant into the open end of a standing pipe Q, which 5 also receives the discharge of water from the io lant, is returned to said supply-pipe to commingle with the current of water flowing therethrough. The eduction-pipe S, through which the mixture of coagulant is conducted from said force-pump, is connected to the I 5 supply-pipe B at a point between the Valvethe water-supply enters the filter.
casing D and the connection of said supplypipe with the filter A, and thereby a perfect commingling of the coagulant with the current of water in the supply-pipe is effected before The float O is maintained centrally in the tank N, and its movements therein are guided by means of a guide-rod T or other suit-able appliance, and said float may be emptied when occasion requires by dipping or siphoning the water out of it.
Myinvention operates in the following manner: The tank N is charged with a supply of liquid coagulant, whereby the float O is 0 buoyed up, and the water from the source of supply is admitted to flow through the supply-pipe 13 toward the filter A. The force of the current of Water flowing through said supply-pipe causes the valve E to open, and
w --g5' the latter, by the mechanism connected thereto, as hereinbefore described, lifts the valve F to allow a portion of the water in said supply-pipe to be diverted therefrom, so as to enter the tank H, wherefrom a part of said diverted water trickles through the drip-pipe K into the float O. The water accumulating in said float causes it to sink gradually into the coagulant, effecting a displacement of the latter, by which its surface is constantly m aintained at such a level that a constant stream of said coagulant will be discharged from the spout P into the standing pipe Q. The surplus of water from the tank H beyond thequantity of said water required for supplying 5ov the float O is conducted through the outlet-pipe L and delivered into the standing pipe Q to commingle with the coagulant delivered thereinto. The pump R forces the diverted water, now charged With coagulant,
to return to the supply-pipe B, wherein it is again commingled with the current of water passing through said supply-pipe to enter the filter A. At the instant the current of water ceases to flow through the supply-pipe B the valve E will close, and coincidently therewith the valve F will return to its seat to close the opening by which the water is diverted to operate the coagulating mechanism.
By this arrangement of the valves, or one that is substantially the same, the flow of the coagulant into the standing pipe Q ceases at the same moment that the flow of water through the supply-pipe B is terminated, and even though the force-pump R continues its movements no coagulant will be injected into the supply-pipe after the current of water has ceased to pass therethrough.
I do not confine myself to the precise mode of construction of the automatic valves as herein shown anddescribed for regulating the discharge of water from the supply-pipe to operate the coagulating mechanism, as any two valves which are connected to have a coincidental opening and closing movement will serve the same purpose.
I claim as my invention and desire to secure by Letters Patent 1.. In a water-purifying apparatus,the combination of a filter Whose supply-pipe is provided with an automatic inlet-valve which is connected to an outlet-valve that controls a discharge-opening from said supply-pipe into a discharge-pipe which branches therefrom, said inlet and outlet valves being fitted to move coincidently in their opening and closing movements, a tank arranged to receive the water from said branch discharge-pipe and provided with a drip-pipe and outletpipe, at coagulant-tank provided with an outlet-spout and containing an open-top float, said float being adapted to receive the water that trickles from said drip-pipe, and a pump connected so as to force the coagulant emitted from said coagulant-tank into said supplypipe, as and for the purpose herein specified.
2. In a water-purifying apparatus, a supply-pipe provided with an inlet-valve adapted to be opened by the force of the water-current which passes through said pipe, said inletvalve being connected to and fitted to move coincidently with an outlet-valve which controls the discharge of water from apipe which branches from said supplypipe, as and for the purpose herein specified.
