SPECIFICATION forming part of Letters Patent No. 417,046, dated December 10, 1889.
- Application led May 9, 1889. Serial No. 310,136. (No model.)
T 0 @ZZ whom it may concern.- i
Be it known that I, CHARLES H. KENDRICK, a citizen of the United States, residing at lVincliester, Cheshire county, New llampshire, have invented certain new and useful improvements in Coagulant or Reagent Feeders, fully described and represented in the following specification and the accompanying drawings, forming a part ot' the same.
This invention is designed to furnish an automatic device which may be actuated by the variations of pressure arising in the cylinder of any supply-pump whichmaybe used to furnish the fluid to such filter. Where a pump has been used to supply the water to a filter, a coagulant-teeder has been constructed with a plunger of suitable proportions connected directly with the reciprocating crosshead or other moving part of such pump, the volume of coagulant delivered by each stroke of the pump being thus proportioned to the volume of the fiuid passed through the filter. By such a construction the proportion of coagulant to each gallon f water passed through the filter could not readily be varied; and the object of my invention is to furnish a construction that may be actuated by the intermittent variation of pressure in the pump cylinder and adapted, at the pleasure of the operator, to deliver a greater or less amount of coagulant at each reci procation of the sup ply-pump.
My device consists in a motor-piston having one side exposed to the variable pressure existing in the cylinder of the supply-pu mp 4and connected with a plunger adapted to draw the coagulant from a suitable receptacle and force it into the filter, and means being provided to regulate the stroke of the motor-piston, and to thus vary the volume of coagulant delivered by the plunger at each stroke of the supply-pump. The means for regulating the stroke of the motor-piston is easily furnished by'inscrting an adjustable stop through the head of the motor cylinder or casing, with which the motor-piston would come in contact at one end of its stroke, and the stroke may thus be made longer orshorter at pleasure.
The invention will be understood by reference to the annexed drawings, in which- Figurel is an elevation ofl a filter with a supply-pump and coagulant-feeder constructed according to myinvention. Fig. 2 isaloni gitudinal section of the coagulant-ieeder on its center line where hatched. Fig. 3 is an end View of the head provided with the adjustable stop and pressure-pipe, the cap upon the stuffing-box being removed. Fig. 4 is an end view of the opposite head with the coagulantcylinder attached, and Fig. 5 an alternative construction in section like Fig. 2.
The apparatus is adapted to feed any kind ot' chemical reagent, whether intended to produce a precipitate in the water or not.
F is the filter; G, the bed of a steam-pump for supplying the saine with water; H, the steam-cylinder of such pump; I, the Watercylinder; J, the piston-rod between the tnn) cylinders; K, the suction-pipe of the pump,
and L the pipe delivering the water to the filter. l
Figs. l and 2 show the coagulant-feeder constructed with cylinders and pistons movable therein, while Fig. 5 shows a coagulant-feeder constructed with ileXible diaphragms.
The cylinder a of the coagulant-feeder is connected by the .pipe e with the interior of the water-cylinder l, and the coagulantpipe b4 from the cylinder l) is connected with a coagulant-tank M and with the filter-pipe L.
In Fig. 2, a is the motor-cylinderg a", one of its heads, having the coagulant-cylinder b attached. c is the motor-piston fitted to cylinder a, and d a coagulant-puinp plunger attached to the piston c by a stem d. a2 is a head at the opposite end of the motor-cylinder, provided at its center with a threaded nozzle 7i., having cap t' to form a stu lling-box.
A screw j, having shank j extended through the stutling-box, is inserted in the nozzle and provided at its inner end with the -stop f, adapted to arrest the stroke of the pist-on c. The pressure-pipe e is shown connected by a passage c in the head a2 with one end of the cylinder a, and the opposite end of the cylinder is shown connected with the atmosphere by a pipe g, provided at its upper end with a cup g', having a screw-cover g2.
Branches m and m connect the coagulantcylinder, respectively, with a tank of precipitant and with the filter, and check-valves m2 are shown inserted in such branch pipes tc permit the movement of the eoagulant through the pipe m to the cylinder Z1 and from the same to the ilter.
The object of the stop f is to adjust the 5 stroke of the piston c to deliver the desired volume of c oagulant from the cylinder l).
The operation of the appara-tus is as follows: The alternate pressure and vacuum existing in the cylinder I produces an interro mittent pressure upon the piston c, the press ure of the atmosphere operating through the pipe g when a vacuum is induced in the cylinder a to force the piston toward the stop f, and to thus draw the plunger (l backward i 5 from the pipe b4. Vhen the pressure is renewed in the cylinder a, the motor-piston c forces the plunger CZ outward and expels the contents of the coagulant cylinder. The movement of the plunger d thus operates to 2o draw the coagulant alternately from the tank M and forces it through pipe m into the pipe L to operate upon the water before the same is filtered. The' cover g2 upon the cup g,at tached to the air-pipe g, is provided with a hole g3 to admit the atmospheric pressure. Vith such construction the cup answers not only to prevent the entrance of dirt or grit to the cylinder @when the air operates through the cup, but it permits the introduction of l 3o oil or other lubricant within the cylinders a and b by placing a suitable supply of such liquid in the cup, the level of the liquid rising and falling in the cup as the motor-piston Y Y moves back and forth.
ter than the piston c, as the pressure in the pipe L is obviously the same as in cylinder I, and the difference of area between the piston c and plunger CZ may therefore be made suitable 1o to overcome the friction of such pistons and of the liquid in the pipes. operating with less friction is shown in Fig. 5, where two diaphragms s and s are shown secured movably at their margins in adjai cent casinfs t and 15 which are o en to one e a p another upon their adjacent sides. The two diaphragms are connected by a rod s2, so that the movements of the larger diaphragm operate upon the smaller. One side of the casing t is provided with the pipe c to connect it with the cylinder I, and the opposite side of the chamber z5 is connected with the pipe b4 to admit the coagulan t, as already described.
A stop f is also shown applied to the outerl side of .the diaphragm s, and its movement in the opposite direction is arrested by contact with the casing t. A pipe t2 admits air between the diaphragms to operate like the pipe g in Fig. 2.
It is obvious that the area of the larger A construction The plunger d requires to be of less diamediaphragm permits it to operate effectively upon the smaller diaphragm to propel the coagulant against the pressure in the pipe L, as desired, and the diaphragms may thus, for the purposes of my invention, be regarded as pistons, vibrated, one of them, by the variations ot pressure in the pump-cylinder I and the other vibrated by its connection therewith. The diaphragm s operates as the motor-piston, and the diaphragm s operates as the pump-plunger to propel the coagulant in precisely the same manner as the plunger (l in Fig. 2.
The term motor piston and plunger used in the claims is intended to cover either of these constructions, provided the motorpiston be of larger area than the coagulantplunger, so as to deliver the coagulant under a pressure equal to that which operates the motor-piston. Thevcylinder a may also be regarded as a casing to eoniine the pressure upon the piston c in the same manner as the casing t contines the pressure upon the diaphragm s, and the term casing used herein j thus includes either construction.
Having thus set forth my invention, what I claim herein isl. The combination, with a tlter and a supply-pump con trolling the passage of the fluid through the iilter and having a fluid-cylinder in which the pressure is intermittingly varied, of a motorpiston in communication with the said pump-cylinder, a coagulant-plunger actuated by such motor-piston, a receptacle of coagulant or chemical reagent, and pipes and valves connecting the receptacle with the filter and with the pump-plunger, the whole arranged and operated to deliver a charge of coagulant into the filter at each reciprocation of its suppl y-pu mp, substantially as set forth.
2. Ina coagulant feeder having a motorpiston actuated by an intermittent variation of pressure upon one side thereof, the combination, with the casings t and t', connected together as described, of the diaphragms s and s', of different diameters, connected together, the pipe c, for connecting the casing t to the pump-cylinder I, the pipe b4, for connecting the smaller diaphragm with the coagulant-receptacle and with the filter, and the stop f, to regulate the movements of the diaphragms, substantially as herein set forth.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
CHARLES H. KENDRICK.
