' IAVID GIBBS, OF SAN FRANCISCO, CALIFORNIA.

FLUSH-OUT.

Specification of Letters Patent.

Patented Dec. 15, 1914.

Application filed June 11, 191B. Serial No. 773,029.

To all whom t may concern.'

Be it known that I, DAVID GIBBs, a citiaen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Flush-Outs, of which the following is a specification.

This invention relates to a flushing valve for water-closet tanks.

It is the object of this lnventionto provide a iushing valve of the loose ball type,

with means for lifting the ball from its seat from'its underside, which is so constructed as to obviate disposing the valve operating mechanism within the tank.`

A further object is to provide a simple and eiiicient flushing valve which is durable and not liable to get out of order. l

The invention primarily resides in a tank having a sloping bottom leading to a flushout pipe, a valve seat at the mouth of the fiush-out pipe, a loose ball adapted to rest on said seat to prevent the discharge of liquid from the tank, and means disposed in the flush-out pipe operable by a hand lever exterior thereof for lifting the ball from its seat.

The invention further consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawing, in which- Figure 1 is a vertical section of one form of the invention. Fig. 2 is a section in ele'- vation on the line a-a of Fig. l. Fig. 3 is a vertical section of a modified form of the invention. Fig. 4 is a horizontal section and elevation on the line b-b of Fig. 3. Fig. 5 is a horizontal section on the line c-c of Fig. l.

lIn the drawings, A represents the bottom of a tank or reseivoir of any suitable construction; the bottom A being inclined downwardly toward its center. Mounted on the bottom A at its lowest point is a tubular v member 2, which is threaded on its exterior and adapted to be vengaged by a threaded sleeve or union'l on a nipple 4 threadedl in the upper end of the elbow 5. The elbow 5 is connected at its lower end with a bowl or other structure, not shown. The member 2, nipple 4, and elbow 5 constitute a Hushout pipe leading from the bottom A of a tank to a suitable point'of discharge.

Interposed between the ends of the member 2 and, the nlpple 4 is a spider or ring 6,

which is supported on the up er end of the nipple 4 and is held in place y a washer 7 clamped between the ends of the member 2 and the nipple 4 by means of the union 3. The ring 6 is formed with transverse ribs which support a central perforated member 9 which serves as a guide and support for a vertically disposed rod 10. The rod 10 is threaded at its upper end and is screwed into a collar 11 on which a ring 12 is sup- 'ported on outwardly and upwardly extending arms or standards 13 on the collar 11. The ring 12 is designed to normally contact the underside of a loose ball 14 seated on the upper open end of the member 2, the ball 14 forming a valve and the member 2 a seat therefor.

In the form of the invention shown in Figs. 1 and 2, the bar 10 is formed with rack teeth 15, on one of its vertical edges, which teeth mesh with a toothed segment 16 mounted on a rock-shaft 17 extending across the interior of the elbow 5 and passing through a stuiiing-box 18 in the latter. The bar 10 is retained in mesh with the segment 16 by means of a guide yoke 19 secured to the interior of the elbow 5; the bar 10 passing between forked members on the guide yoke 19, as shown in Fig. 1.

In the form of the invention shown in Figs. 3 and 4,' the lower end of the bar 10 is pivotally connected to an arm 16 secured to the shaft 17. Wound on the bar 10, and bearing between the guide member 9 and a pin 20 on the bar 10, is a spring l21 which acts to normally retain the bar 10 in its lowermost position. The shaft 17 is provided with a hand lever 22, exterior of the elbow 5, byv means of which the shaft 17 may be rocked.

lVhen the ball 14 is disposed on its seat and the tank is filled with water, or other liquid, the ball will be held in its seated position by the weight of the liquid there' above. l lVhen it is desired to discharge the this occurs the ball, by reason of its being thereby leaving the upper end of the iiushj' out open so that the contents of thetank constructed in such manner as to float, will lrise to the surface of the liquid in the tank,

will be rapidl discharged therefrom.

Upon releasing t e handle 22 the spring 21 will operate to restore the rod 10 to its normal' lowermost position. When the tank is empty the ball 14 will be caused to roll down the inclined bottom A. into position on the valve seat member 2, thus closing communication between the tank and ilush out pipe so that the latter may be refilled. p

By thus constructing the valve operating mechanism and disposing it within the lush,

out pipe, and by forming the tank with a sloping bottom A, the use of cages for guiding and directing-theball 14 and the valve operating mechanism within the tank is dispensed with.

In some instances the handle 22 may be weighted sufficiently to restore the bar 10 to its normal position on releasing the handle, in which event the spring 21 may be dispensed with.

Having thus described my invention, what ent 1s-' l v l In combination with a tank having a discharge and a tube therein, a l spider connected claim and ldesire.tesecure by Letters Patto the tube, a rod slidable in the. spider, a'

ball, a ring to support the ball, an interiorly threaded collar having its base seating on top of the spider, spaced divergent arms connected to the collar and ring, a rod slidable through'the spider and threadedly connected to said collar, a spring connected to and surrounding the rod and abutting the lower side of the spider, a pivoted upwardlyA ,movable handle to actuate the rod and means to operate the rod from the handle, said handle being limited in its downward movement b engagement of the collar with the upper ace of the spider.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. p

DAVID GIBBS.
