LUDWIG Woman, on CHICAGO, ILLINOIS.
Specification forming part of Letters Patent No. 131,924, dated October 1, 1872.
To all whom'it may concern.-
Be it known that I, LUDWIG WOLFF,'Of the city of Chicago and State of Illinois, have invented a new and'useful Improvement in the Construction of Hopper-Valves, of which ing used; Fig. 2 is a section, showing the position of the plunger when the closet is not being used; and Fig. 3 is a horizontal section. My invention relates to the arrangement of two plungers and a spring inside of a valvechamber in such a manner that the difficulties hitherto connected with hopper-valves are perfectly overcome. These difficulties now are, the great power which is required to work the hopper-valves on account ofthe heavy spring which works against the pressure of the hydrant-water, and the force and trouble required in putting the different parts of these valves together. Another serious objection against the valves now in use is the waste of water, as the waste-pipe of these valves is not only letting off the water which has collected in the valve-chamber, but is wasting Water constantly as long as the closet is in use.
In the drawing, a represents the pipe which connects the valve with the hydrant; b, the pipe connecting with the closet. A represents the body of the valve-chamber. c is the lower and d the upper plunger; 6, the rod of the lower plunger, which passes partly into the upper plunger, which forms a guide for the movement of the lower plunger. The upper plunger is provided on its lower face and the lower plunger on its top face with a leather washer or packing to make them fit tight on v the lower and upper faces of the rim g. The
water from passing the valve. I use a very light spring, just strong enough to lift the plungers. A little piston, k, passes through the valve-head r and rests against the upper plunger; but between them is an elastic packing, Z, which closes the top of the valve and allows the piston to work easily. m is a small pipe to let off the waste water, having a small opening in the upper face of the rim y, where it can be shut off by means of the upper plunger.
When the closet is in use the piston k is pressed down upon the upper plunger d, which moves downward and causes the plunger 0 also to descend by compressing the spring h. As soon as the upper plunger closes on the top face of the rim 9 it can move no further, thereby protecting the spring h from being strained or pressed out of shape. In this position of the plunger the water can pass freely from a to b-that is, from the hydrant to the hopper of the closet. Meanwhile the upper plunger 61 closes the opening of the waste-pipe m, in the upper face of the rim g, thus preventing a waste of water while the closet is being used. When the closet is left the spring h moves the lower plunger upward till it reaches the lower face of the rim 9 and shuts off the water of the hydrant; and as, by means of the rod 6, the upper plunger is also raised, the waste water can flow off through the pipe m, thus keeping the valve-chamber dry and preventing the water from freezing therein.
The whole valve can be put together in one minute. The piston 70 is put in the head 1';
the upper plunger is put in the valve-chamher, and the packing I laid in its place, when the head 1" is screwed on. The valve is next turned around, when the lower plunger 0, with the spring h, is put in place, and the bottom G is readily screwed on and secured in proper position.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
A hopper-valve constructed with the plungers c and (1, rod 0, and piston is, in combination with the springh, rim g, and valve-chamber A having the pipes 0gb, and m, all being constructed and arranged substantially as and for the purpose set forth.
LUDWIG WOLFE.
