Application filed August 1. 1885. Serial No. 173,295. (No model.)

To all whom it may concern:

Be it known that I, Joseph C. Higgins, a citizen of the United States, residing at New Brunswick, in the county of Middlesex and 5 State of New Jersey, have invented certain new and useful Improvements in Automatic Water-Pipe-Feeding Attachments, of which the following is a specification.

My invention relates to the process of pnriio fying water by impregnating it with a coagulating agent: and the object of my invention is to insert the coagulant, in form of a solution, automatically into water-pipes, for the purpose of saving the time and trouble of first-drawing 15 the water and afterward inserting the coagulant. I attain these objects by the mechanism illustrated in the accompanying drawings, in which—

Figure 1 is a cross-section of the entire ma-. 20 chine; Fig. 2, a longitudinal section; Fig. 3, end and top view of cylinder; Fig. 4, bottom view of cylinder, cam, and cut-off; and Fig. 5, side and top view of cam.

Similar letters refer to si milar parts throngh25 out the several views.

Referring to the drawings, K represents the case or outer covering of the machine. The shaft a is supported by and rotates in the bearings J J, which are attached to the innersides 30 of the case K. This shaft a carries an ordinary motor-wheel, H, cam D, and a cylinder, A, all of which are fixed rigidly to said shaft.

The cylinder A is mounted within a cylindrical chamber, J, of the box B, and in which 35 it revolves. In the outer surface of the cylinder Ais one or more pockets or receptacles, bb. The circumference of the cylinder A corre-.. sponds exactly in size with the periphery of the cylindrical chamber j in the box B, so as 40 to form a perfectly tight-fitting joint. In the upper surface of the box B is an aperture to admit of the passage of liquid from the vessel G through the duct F into the pockets b b.

To unload the pockets and prevent them 45 from returning filled with the water from below, I use a cut-off arranged in the following manner: e is a horizontal arm extending outward from the side of the box B,-and starting from a point just above the apertureg. Upon 50 the under side of this arm e are two lugs, d d, projecting downward and having holes there- _; in, which support the handle of a cut-off gate, C. The gate C passes through the aperture <7, with its upper side lying closely to the upper edge of the aperture. 55

The inner edge of the gate C rests against the cylinder A. Said gate corresponds in width with that of the aperture g. A spiral spring, c, is interposed between a pin, i, which is inserted through the handle of the cut-oil 6c gate C, and the outer lug, d, to hold the gate tightly to its place against the cylinder A. This also allows of a backward and forward movement of the gate C, which is necessary in its operation of passing in andouto.f thepock- 65 ets b b.

To prevent any friction from the cut-off gate 0, and thereby prevent wear on the surface of the cylinder A between the pockets b b,a spur, f, is provided, which projects laterally from 70 the cut-off gate C and extends to a cam, D. This cam gives a reciprocal motion to the cutoff, which, raises and drops it automatically off and on the surface of the cylinder at certain required points. 75

- To keep asolid bearing,and prevent leakage from wear between the cylinder A and the upper surface of the cylindrical chamber of the box B, a rod, E, extending· downward from the bottom of the box B through the bottom of 80 the case K, can lie tightened, when necessary, from the outside of the case K by means of the thumb-nut h.

L is the inlet water-pipe, and M the outlet. As the water is put in motion while being 85 drawn off, the force thus produced is thrown on the motor-wheel II from the inlet-pipe at L, which rotates the driving-shaft «, and this, in turn drives the cylinder A, and by these means the pockets b b are filled with the co- 90 agulating solution from the vessel G, and are carried around to the opening //when the contents of the pockets are forced out clean, and they return empty, as before, ready to receive another charge. 95
