SIPHON FOR WATER-CLOSET TANKS.

Specification of Letters Patent.

Patented Nov. 17, 1908 Application filed February 4, 1907, Serial No. 355,608. Renewed October 9, 1908. Serial No. 456,947.

To all whom it may concern:

Be it known that I, WILLARD F. RICHARD- SON, a citizen of the United States, residing in the city and county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Siphons for WVater- Closet Tanks, of which the following is a specification.

This invention relates to improvements in siphons for water-closet tanks.

The object of this invention is to provide an improved water-closet tank siphon which is very economical to produce and at the same time one which is desirable and durable in construction with improved detachable guide for the valve lift rod or stem.

I accomplish the object of my invention by thedevices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which,

Figure 1 is a perspective view of my improved Water closet tank siphon, a portion of the valve being broken away. Fig. 2 is a detail vertical section through the valve seat. Fig. 3 is a detail section, taken on a line corresponding to line l-et of Fig. 1, the valve lift rod or stem being removed from the guide therefor.

In the drawing, similar reference characters refer to similar parts throughout the several views.

Referring to the drawing, my improved siphon consists of a body or gooseneck portion 1, havinga laterally projecting dis charge arm at its lower end, the discharge arm having preferably a threaded nipple 2 adapted to receive a suitable coupling. Above the nipple 2 is an upwardly opening valve seat 3. The loop of the gooseneck is strengthened by the brace 5. The end 6 of the siphon is cut on an incline to provide a suitable vent as is usual in such structures. On the inside of the gooseneck is a projecting lug 7 having a rectangular vertical hole 8 therethrough adapted to receive the downturned end 10 of the lift rod guide arm 9. The parts above described with the exception of the lift guide arm are all cast in one piece. The lift guide arm is provided with a vertical guide-hole 12 therethrough adapted to receive the lift rod or stem 13 of the valve 1st. The valve seats downwardly, as clearly appears from the drawing. As the valve seat is cast integrally with the other parts, and preferably of iron, I preferably provide a seat ring 15 therefor. This seat ring is adapted to fit within the valve seat and forms, in reality, the seat proper, for the valve. The ring 15 is provided with an outwardly projecting flange 16 at its upper edge adapted to rest upon the top of the valve seat when the ring is inserted in position. This ring is suitably secured in position, which, on account of its shape is very easily accomplished.

The hole in the lug 7 for the lift rod guide arm is formed so that the guide arm is always held in the proper position. In the accompanying drawing, I illustrate the same as being rectangular in cross section, however, it is evident that it might be greatly varied as long as it is of irregular cross section to retain the arm positively in position. By thus supporting the lift rod guide arm, I avoid the necessity for clamps for securing the same, and, as stated, it is always held in proper position. Another very great advantage is that it can be removed and inserted by an inexperienced person, no care being required for adjusting the same.

My improved siphon is very economical in structure and very durable. By casting the parts in one piece, I avoid the necessity for joints, and consequently expense and likelihood of imperfections.

I am well aware that detachable arms have been provided on these siphons with vertical guide-holes for the stems of the ball valves or similar valves which are adjustable and removable by means of set-screws and the like. These require machining and screw-tapping and threading and the insertion of screws. They are very likely to become displaced and are not so effective as the simple castings which I have produced.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a structure of the class described, the combination with a gooseneck or body portion having a laterally extending discharge arm at one end thereof, provided with a downwardly projecting threaded nipple and an upwardly opening valve seat; a lug having a vertical rectangular hole therethrough projecting laterally over said discharge arm, the saidv parts being cast integrally; a valve; a lift rod therefor; and a guide arm for said rod having a downturned rectangular portion adapted to be inserted in said opening in said lug, and a vertical guide-hole at its outer end adapted to receive said lift rod stem whereby said valve is supported and held in alinement with its seat and detachably connected to said body portion.

2. In a structure of the class described, the combination with the body or gooseneck having a laterally projecting integral lug thereon, said lug having a vertical rectangular hole therethrough; avalve; alift rod or stem therefor; a guide arm therefor having a rectangular downturned inner end adapted to be inserted in said hole in said lug, and a vertical guide-hole at its outer end adapted to receive said lift rod whereby said valve is detachably supported and held in alinement.

3. In a structure of the class described, the combination with the body or gooseneck having a laterally projecting lug with a vertical hole of irregular cr0ss-section therethrough; a valve; a lift rod or stem therefor; a guide arm for said lift rod or stem having a downturned inner end conformed and adapted to be inserted through said hole and a vertical guidehole in its outer end adapted to receive said rod as specified.

In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
