DRAINAGE DEVICE.
Application .fileil January 11, 1928. Serial No. 245,953
invention relates to a drainage device applicable to drainage systems for bath tubs, wash barns and any other plumbing fixture rcquii ing a trap on its drainage It appertains more particularly to a device including an overflow pipe. The primary object of this invention is to provide a device of the character described which will drain plumbing fixtures noiselessly and will normally maintain a seal between the overflow and waste thereby preventing circulation of air through the device, minimizing the evaporation of the scaling liquid and prolonging the life of the seal. Another object otthis invention to provide a device of the character described having a shallow seal to permit air arrested between the liquid in the fixture and the seal in the device to be rapidly released through the overflow. A further object of this invention is to provide a device of the character described which after the initial release of the arrested air will maintain a column of liquid in the overfiow and thereby prevent induction ol" air.
" A still further object or this invention is to provide a device which will flush he over- ;"iow at each drainage operation and will by its siphonic action and rapid rush of liquid scour the walls of the fixture and carry off any objects w ich are capable oi pass o through the Lzture. in addition to the broader objects or" this invention, there are certain details of structure whereby a device wh ch is simple and compact, permitting to be installed in a shallow space below and close to the fixture is obtained.
ther objects and advantages will be made fully apparent from the following specification considered in connection with the accompanying drawings, in which:
Fig. 1 is a side elevation of a fragment of a bath tub with my improved drainage device connected thereto; Fig. 2 is a central sectional view through the device; and Fig. 3 illustrates the invention applied to a tub adapted to be disposed flush with the floor.
Referring with more particularity to th Figs. 1 and 2, a bath tub of a conventional type is indicated by l. The tub is provided with the usual outlet 5 and adjacent the top with an overflow outlet (3. By means of pipe fittings indicated generally by 7 the waste outlet 5 is connected to a. nipple 8. The nipple 8 is threaded into a waste branch 9 of the device. The device as shown comprises a discharge branch 10 and an overflow branch 11. Connected to the overflow branch is a nipple 12 to which is secured an i. 13. The L 13 is connected by pipe fittings and a nipple 14 to tho overflow pipe 15 which leads to the overflow outlet 6. Con nected to the discharge branch 10 is a nipple 16. It will be noted that a w 3 head of Y shape has been provided. .rlithough it is not shown as made integral, yet it obvious that it could be so made. Furthermore, the waste branch 9 may, if desired, be construe-i;- ed similar to the overflow branch. This would permit variation of the length and character of the branches to accommodate various installations. However, the waste brancn must in each case be of Y shape haing a crotch 17. A trap 18 is connected to the nipple l6 and extends upwardly so that the lowest point is slightly above the level of the crotch. A nipple 19 serves :tor connection or" the trap to drainline 20.
In Fig. 3 a. fragmentot' a tub set fiush upon the floor is shown fragmcntarily and designated by i. A waste plug 21 connects the outlet of the tub to the waste branch ot' the head. 'A gasket 22 provides for a leak tight connection. It will be noted from this figure, that the thread of the waste plug may be made short and of heavy material allowing the yoke to be set up tight to the bottom of the fixture eliminating all slip joints on the waste branch under the tub or fixture and thereby allowing the water in the trap and yoke to lay ata level close to the bottom of the fixture and yet not allow any water to lay in the bottom of the fixture. This minimizes the fouling of the branches from the bottom of fixture to the seal of the trap. The structure is such that the device can be installed close tothe fixture and is adaptable to installation between flooring joists saving cutting of valuable joist supports and saving many parts with a minimum of subsequent maintenance. By the use of a nipple or threaded pipe connections between the trap and the branch 10, the waste may be brought to any point from the fixture thereby rendering it universal and water tight fitting.
Suppose the tub is filled to its normal height and that the waste plug is removed for drainage. The level of water in the head is as indicated by the dash and dot lines in Figs. 2 and There will be some air entrapped or arrested between the water in the fixture and the sealing water. This is forced downwardly by the water in the Ill) I tub as it enters the waste head. The level.
of the water in the waste head is finally lowered below the crotch 17, permitting the arrested air to pass upwardly through the overflow pipe. The water from the fixture following through the waste head passes upwardly into the overflow pipe. The overflow pipe is now unsealed. rushes from waste head through the trap and'into the drain line, thecolumn of water in the overflow pipe preventing the induction oi air into the waste head. In the fixture of this character usually and commonly installed, there is an induction of air through the overflow pipe which causes a disagreeable noise. However, with my trap and waste head the induction of air during drainage is prevented. l iu therinore, surging of water in the overflow pipe results which causes flushing of the latter. The water finally drains from the tub until it reaches the level indicated by the dash and dot line, whereupon drainage and flow of water ceases. It will be noted that the waste branch is sealed from the overflow branch. ln the ordinary fixtures, there is a circulation of air through the waste branch and overflow branch. This causes foul air to enter the room, and also increases the evaporation and decreases the life of the seal. lVith my waste head this is prevented. Due to the siphonie action and the size of parts permitted, there is a rapid rush of water through the device resulting in a quicl: drainage, tendin to prevent the overflow of fixtures and thereby doing away with the liability of leakage through the floors and ceilings. It will be noted that the Y waste head is connected to the trap so as to provide a shallow seal. There is a primary waste and a secondary waste from the fixture both connected by a common discharge branch to the trap. The outlet of the trap The water has its lowest point just above the crotch in the head. This provides a seal that is easily broken to permit air entrapped or arrested in one ofthe waste lines to escape. Thus, the head is relieved of air and unobstructed flow of the waste water is permitted.
Vi hat'l claim is:
1 A drainage device comprising a Y waste head including one branch or con nection toa primary waste from a plumbing fixture, a second branch for connection to a secondarywaste from said fixture,-a common discharge branch at the fork thereof,- a trap connected to'said discharge branch and having an outlet with its lowest water level slightly above the water level of the crotch of said head whereby to provide a shallow seal normally closing both the priinary and secondary branches and; enabling the seal to be easily broken and the escape of arrested air from one branch to the other.
2. In combination with a; plumbing fixture having an overflow and'a waste,- a drainage device comprising a Y waste head including an upwardly extending waste branch connected to the waste of said fixture, an upwardly extending overflow branch connected to the overflow of said' fixture,-a downwardly extending dischargebraneh, and atrap connected to said discharge branch having an outlet with its lowerwater level slightly above the water level at the crotch of said head whereby to provide a-shallow seal normally closing botlr the-waste branch and the overflow branch and enabling the seal to be easily brokenand escape of air from one of said last mentioned branches to'the other.
In witness that I claim the foregoing I have hereunto subscribed my name this 31st day of December, 1927;
DANIELA. DEACON. I
