AUTQMATlG FLUSHING APPARATUB.

SPECIE'ECATTQN forming part of Letters Patent No. 816,966, dated May 5, 1885.

- Application filed December 27, 1551. (No model.)

To all whom, it may concern:

Be it known that I, BYRON J. HEALY, a cit-izen of the United States, residing at Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented a new and useful Automatic Flushing Apparatus, of which the following is a specification.

This invention has for its object certain improvements designed to simplify and cheapen the construction and greatly facilitate the op eration of flushing.

In the drawings forming apart of this specification, in which like letters point out like parts, Figure 1 is a side elevation with the flush-tank and eduction-port in vertical section, Fig. 2, an enlarged broken detail of Fig. 1, illustrating the operation 5 Fig. 3, a broken detail of said figures in enlarged perspective; Fig. 4, a top view of the flushing apparatus; Fig. 5, enlarged detail of Fig. 1; Fig. 6, an enlarged detail of Fig. l with valve in section; Fig. 7, same as Fig. 5, looking from a point at the left hand of the latter figure, illustrating operation of said part, and Fig. Sis a detail of Fig. 1, looking from a point at the left hand of the part in said figure.

Referring to the drawings, A in Fig. 1 shows a flush-tank made in the ground with detachable cover at the top, in common use in connection with sewers. B shows a broken sewer, and F an eduction-port leading from the tank A to the sewer R.

The foundation-plate a of the apparatus forms the seat of the valve h, said valve being hinged at 3 The hingingeye is vertically elongated, Fig. 6, to allow the pivot of the hinge therein to play slightly, so that the valve will seat squarely.

The frame consists of bar D, preferably forked at the lower end and elbowed at the top, forming a horizontal arm, E. The bar 1? is bolted to the arm E and extends a little above said arm. The elbow operating-lever a is pivotally connected at the turn of the elbow with the upward extension of bar P. \Vith the upper end of the elbow of lever a is pivotally connected the rod which rod is jointedly connected with the valve 71. The arrangement of these parts is such that, when the valve h is closed, Fig. 1, the pivot which connects the connecting-rod r with the operatinglever a will be a little at the left of a vertical line intercepting the pivot of said operatinglever, thus forming a lock to hold the valve it closed.

S is a set-screw, which may be employed, if need be, to properly adjust the operating lever in relation to said locking capacity. The outer free end of the lever a is forked, Fig. 4. Centrally between the arms of said forked end a float, B, is flexibly connected with said arms by chains 0 c or equivalents in a manner that the float may rise and fall between the arms with the rise and fall of the water. By this plan of construction, the float performs its required work with no danger of conflicting with the operating-lever, or of floating about on the water.

In Fig. l the rising water has just reached the float B. The float continues to rise with the rising water until in the position shown in Fig. l by dotted lines, or substantially in said position, the horizontal dotted line in said figure showing high-water limit, at which time the lifting-float trips the lever a by raising it, when said lever flies up to the position shown in Fig. 2, the connecting-rod r is carried downward, and the valve 71 swings downward, as shown by dotted lines in Fig. 6, allowing the water to escape through the eduction port into the sewer. As soon as the water all escapes the operating-lever and float, being heavier at the left of its pivot than the weight of the portion at the right and its con nections, fall to place again, closing the valve h, as in Fig. 1.

An indicator or register is shown at x, having an arm, n, with which the operating-lever a comes in contact in its upward movement, thus registering on the dials the number of times the tank fills and empties in a given time.

The details of the indicator are not shown, because any suitable indicating device may be used in the relation stated.

I prefer to construct the connecting-rod as shown in Figs. 5 and 7. The rod is severed, the severed ends headed and lapped past each other, and a spiral spring located around the rods where they lap and between the heads t of the ends. An upward strain on the rod from the top compresses the spring if, so that the spirals touch each other, Fig. 5. When the strain from said end is removed, the spirals separate, as in Fig. 7.

In the operation, the compressing of the spring admits of a sure lock of the operatinglever by allowing it to fall sufliciently far when closing the valve. At the time the op crating-lever to looks the spirals touch each other, making the rod solid against any endwise expansion by a downward pressure of the water on the valve. The expansive tendency of the spring assists the float in tripping the operating-lever a and causing a quick movement of the same, so as to let the valve swing open suddenly, letting the full stream of water pass out at the start. The spring remains expanded, Fig. 7, until the operatinglever falls to place again in closing the valve.

The upper end of the connecting-rod 1' may be provided with a recessed coupling, 0, and threaded end and jam-nut o, to adjust the length of the rod.

Having thus described my invention, what I claim is 1. The combination of a hinged valve at the eduction port, adapted to swing open by the pressure of the water when released, a supportingframe having the horizontal arm and upward extension, an elbowed operatinglever pivoted to said extension and provided with a float, and a connecting-rod pivoted to the upper end of the elbow-lever and jointedly connected with the valve, substantially as set forth.

2. The combination, with a valve hinged to swing open, of an operating-lever having the forked end and flexibly-connected float, and a rod connecting the operating-lever and valve, substantially as set forth.

3. The combination of the swinging valve, supporting frame, pivoted operating lever, and connecting-rod consisting of the severed headed lapped rods provided with the spring, all substantially as set forth.

4. The combination of the swinging valve, forked elbow operating-lever, float, adjusting set-screw or equivalent, and supporting-frame, and the connectingrod having the upper threaded end, recessed coupling, and jam-nut, substantially as set forth.

5. The combination of a supporting-frame, an elbow operating lever pivoted to said frame at the turn of the elbow, a float connecting with said lever, a swinging valve, and a connecting-rod connecting the upper end of the elbow with the valve, andprovided with a flexible portion to facilitate the locking of the operating-lever, and to accelerate its movement when tripped, substantially as set forth.

6. The combination, with a registering device having an extended operating-arm, of a flushing apparatus having an operating-lever adapted to swing in contact with said operating-arm when the flush-valve opens, for the purpose stated, substantially as set forth.

In testimony of the foregoing I have hereunto subscribed my name in presence of two witnesses.
