ARTHUR M. HOUSER, OF CHICAGO, ILLINOIS, ASSIGNOR TO CRANE COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

CLOSET-FLUSHING MECHANISM.

Application filed March 9, 1910.

To all whom it may concern Be it known that I, ARTHUR M. Hoosnn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Closet-Flushing Mechanism, of which the following is a specification.

The invention relates to closet flushing mechanism and particularly to the hinge connection whereby the movement of the seat secures the actuation of the flushing sembled, in which the number of the parts is reduced to a minimum and in which the parts of the mechanism are securely and rigidly maintained in alinement. bodiment of the invention is illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation of the entire apparatus,

Figure 2 plan view of the hinge connection,

Figure 3 is a section on the line IIIIII of Fig. 4:,

Figure 4 is a section on the line IVIV of Fig. 3,

Figure 5 is an end view of the fastening means at the left hand end of the operating shaft in Fig. 3, and

Figure 6 is a perspective view of the end of the operating shaft.

Referring to the general arrangement as shown in Figures 1 and 2, the principal parts shown may be enumerated as follows. 1 is the bowl; 2 is the seat; 3 is the casing of the flushing valve; 4: is the admission pipe leading from the main; 5 is the storage tank; 6 is the pipe leading from the casing of the flushing valve to the storage tank; 7 is the operating shaft for the valves in the casing; and 8 is the seat bracket, which seat bracket is provided with the arms 9 and 10 secured to the opposite ends of the operating shaft 7.

The construction of the flushing valve and the means whereby the shaft 7 is con- Specification of Letters Patent.

nected to operate such valve is shown in detail, in Figures 3 and at. As here shown the casing 3 opens downwardly at 11 into the bowl, and carries the pair of valves 12 and 13 upon the stem 14, which stem and valve are normally held in the position in dicated in Fig. 4 by the spring 15. The stem 14 carries screw threaded thereon, the collar 16, which collar is provided with the laterally projecting arms 17 (Fig. These arms 17 are engaged by a pair of downwardly projecting arms 18 projecting from the collar 19, which collar 19 is mounted on the operating shaft 7. The side of this collar 19 is cut away as indicated in Fig. 4 and a projection 20 causes the collar to rotate with the shaft 7.

As indicated in Fig. 3 the shaft 7 projects through the opposite sides of the casing 3 and stuffing boxes 2-1 and 22 are provided at these points to prevent leakage. The ends of this shaft 7 are squared and screw threaded as indicated in Fig. 6, and the arm 9 of the bracket 8 fits the squared end of the shaft as indicated in Fig. 3 and is held securely in position by means of the nut 23. The other arm 10 of the bracket 8 is provided with a larger opening as indicated in Fig. 3, and this opening carries a square bushing 24: the interior of which is squared to lit the end of the shaft 7. The arm 10 and bushing 2d are held in position by means of the nut 25. The opening through the arm 10 is sufficiently large to permit of the passage of the shaft 7 in assembling, and this permits the bracket 8 to be made in one part instead of two parts as has heretofore been the case. The making of the shaft 7 in one piece is also advantageous and superior to the previous arrangement in which such shaft was made in two separate pieces, in that the ends of the shaft are maintained in alinement and there is no tendency to twist in the stufling boxes, as is the case where two independent shafts are employed. Leakage at the stufiing boxes is in this manner practically eliminated, and the necessity of repeated adjustment avoided. The making of the bracket 8 and the shaft 7 in one piece also simplifies and cheapens the construction, and this, without in any way increasing the difliculty of assembling the parts. When once assembled the structure is very rigid and secure. Other advantages incident to the structure will be apparent to those skilled in the art.

The operation, starting with the parts in the position indicated in Figure 4 is as follows: The seat 2 being depressed the shaft 7 is rotated thus rotating the sleeve 19 and forcing the stem 14 and the valves 12 and 18 to the left. This opens communication between the inlet pipe 4 and the pipe 6, permitting the tank to fill, and at the same time closes communication between the pipe 4 and the bowl. Upon releasing the seat 2 the spring 15 carries the two valves to the right and lifts the seat to the position indicated in Fig. 4. This movement of the valves cuts off the supply of Water from the pipe 4: and permits the water from the tank to flow down through the pipe 6 past the valve 12 and through the opening 11 and into the bowl of the closet.

Having thus described my invention and illustrated its use what I claim as new and desire to secure by Letters Patent is the following l. A valve operating mechanism comprising a casing in Which the valve is mounted, a transverse operating shaft extending through opposite sides of the casing, and a member for imparting a rotary movement to the shaft extending on opposite sides of the casing and provided wit-h openings to receive the ends of the shaft, one of said openings being large enough to permit the passage of the shaft therethrough in assembling, and a bushing for fitting in such opening and securing the shaft against rotation in the said member.

2. A valve operating mechanism comprising a casing in which the valve is mounted, a transverse operating shaft extending through opposite sides of the casing, and having a polygonal end, and a member for imparting rotary movement to the shaft having two arms extending on opposite sides of the casing, one of said arms having an opening large enough to permit the passage of the shaft therethrough in assembling and the other arm having a polygonal shaped opening to receive the polygonal end of the shaft, and a filling block in the first hole and surrounding the shaft.

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