This invention relates to a douche. An .object of the invention is the provision of a device in which a cylinder is provided having a freely movable piston thereinand normally supported by a solution in the lower portion of the cylinder, a nipple being in communication `with the upper end of the cylinder between the piston and the removable top for supplying a iiuid under pressure to a space between the piston and the top for forcing the piston downwardly, thereby forcing the solution in the cylinder from .a discharge passage under pressure, a manually operable valve controlling the discharge passage and a spring normally maintaining the valve closed to prevent loss of from the cylinder.

A further object of the invention is the provision oi a device including a cylinder having a freely movable piston supported by a liquid adapted to be discharged under pressure from the cylinder at the lower end thereof, pressure applied to piston through a connection with the usual water supply of a building at a point between the piston and the closed upper end of the cylinder, the piston of the cylinder beine provided with a discharge passage having a discharge port opening centrally through the bottom of the cylinder which is adapted to be closed by a valve on the lower face of the piston when all of the liquid below the piston has been 30 discharged, thereby preventing the discharge of water from the upper end of the cylinder, a spring-pressed valve normally maintaining the discharge passage closed with means being employed for manually operating the 'valve when desired.

This invention will be best understood from consideration of the following detailed description, in view of the accompanying drawing forming a part of this speciiication; nevertheless, it

41') is to be understood that the invention is not coniined to the disclosure, being susceptible of such changes and modifications which shall define no material departure from the salient features of the invention as expressed in the appended claims.

in the drawing: Figure 1 is a View in elevation of a device constructed in accordance with the principles of my invention, and shown applied to the usual water supply of a building,

designates preferably a cylinder formed of hard (Cl.` 12S-229) rubber, composition material, or any kind of metal suitable for the purpose. An integrally formed bottom l1 and a removable top 12 are formed of the same materials.I The top is threaded, as shown at 13, upon the upper reduced end 14 of the cylinder l0.

An integrally threaded hollow boss 15 projects from the side wall of the cylinderV l adjacent the removable top 12. Into the hollow boss is threaded a nipple 16 having a centrally disposed passage i5 17 in connnunication with the cylinder l0. TheY nipple 16 is provided with a shoulder 18 adapted to engage the outer end of the boss for limiting the inward movement of the nipple so that the extreme inner end will be ilush with the inner face of the cylinderlO for a purpose which will be presently explained. The extreme outer end of the nipple, as shown at 19, is enlarged to receive the end of a rubber hose 2G, thereby increasing the pressure of thev hose on the nipple l5 and preventing slippage of the hose fromsaid nipple.

The hose, as shown at 21, is connected to the free endv of a faucet 22 and this faucet has the usual valve controlled by a handle 23. The faucet is connected with the water supply of a building.

The bottom 1l is provided with a radial passage 25 and this passage vextends to the center of the bottom and terminates in a port 25 formed in a concentric boss 27 located at the inner face of the bottom 11. I

An angularly formed pipe 28 has a horizontal branch portion 29 and a vertical portion 30. The horizontal portion is threaded at 31 into the bot,- tom 11 and in alignment with the passage 25 so that a tapered passage 32 in the branch 29 will be in communication with the discharge passage 25. The vertically disposed branch is also provided with a passage 33 which is adapted to be placed in communication with the passage 32.

The outer end of the branch 30 is provided with an enlargement 3e to receive one end of a rubber hose 35 and the enlargement prevents slippage of the hose from the branch pipe 30. The hose 35 may be of any suitable length and is adapted to have appliedto the outer free end any instrumentalities that may be necessary for the purpose.

A piston valve 4e is slidably mounted in the tapered passage 32 at a point adjacent where said passage joins the passage 33 so that the piston valve under the influence of a spring 41 will normally maintain said valve in a position to close the passage 33 from the passageV 32 and prevent loss of fluid from the lower end of the cylinder i0.

The spring is seated within a barrel 42 threaded onto a plug 43 which is formed integrally with the outer end of the branch pipe 29. A stem 44 is connected to the valve 40 and projects through the outer end of the plug 43. A knob 45 is secured to the outer projecting end of the stem 44 whereby the valve 40 may be moved inwardly against the tension of the spring 41, thereby placing the passages 32 and 33 in communication with each other to permit the discharge of liquid from the lower end of the cylinder 10. A flange 46 is secured to the stem 44 and is engaged by the spring 41 for moving the valve 40 outwardly to engage a seat 47.

A piston is located in the cylinder 10 and is adapted to be normally supported by the liquid in the lower end of said cylinder. This piston has a body section 50 preferably formed of brass or any suitable material which is circular and is adapted to neatly rit within the cylinder 10 and having sliding contact with the inner walls of said cylinder. The body member is provided with ribs 51which will increase the weight of the piston. The ribs 5l terminating in engagement with the inner walls of the cylinder 10 will aid in maintaining the piston in a normal hori- Zontal position at all times.

The underface oi' the body 50 of the piston is provided with a central boss 52 which receives a soft rubber washer 53, a hard rubber washer 54 of less diameter than the washer 53 and a sec ond soft rubber washer 55 is placed in engagement with the hard rubber washer 54. A metal plate 56 is threaded at 57 onto the lower end of the boss 52 for maintaining the three rubber washers in position. 1t will be noted that the soft rubber washers 53 and 55 have their peripheries in snug engagement with the inner walls of the cylinder 10 in order to seal the piston against leakage of fluid upon opposite sides of said piston, A valve 58 formed of soft rubber is imbedded within a recess 59 in the lower end of the boss 52 and is adapted to engage the port 26 and close the same when the piston has moved to its lowermost position, thereby preventing the loss of liquid from the cylinder when the piston is at its lowermost position.

The operation of my device is as follows: The desirable solution adapted to be employed is placed in the lower end of the cylinder y10 after the top l2 and the piston have been removed.

.also with the faucet 22 so that when the valve is operated by the member 23 water pressure from the water supply of the house will be exerted on the piston in the cylinder andabove said piston so that when the stem 44 is forced inwardly against the tension of the spring 41, the fluid will be discharged through the passage 25 and through the hose 35. When the piston has moved downwardly to its lowermost position, the rubber valve 53 will engage the upper end of the boss 27 and close the port 26, thereby preventing the water from the upper end of the cylinder and normally located at the upper side of the piston, from being discharged from the cylinder.

I claim:

1. A douche comprising a cylinder provided with a centrally disposed boss and a radial conduit extending at the inner end thereof through the boss and opening into the cylinder, a valve 150 casing having a conically-shaped passage in cornlmunication with the outer end of the conduit, a

manually operated spring-pressed o onicallyshaped valve at the reduced end of the passage, said cylinder adapted to'contain a liquid, and a 105 piston floating on the liquid for creating presure on the liquid in the container and for forcing the liquid from the valve casing when the valve is opened.

2. A douche comprising a cylinder having a 3 1@ closed bottom provided with a centrally disposed boss and a radial conduit extending the boss at the inner end thereof and opening into the cylinder, a float piston in the cylinder and adapted to rest upon an antiseptic solution in said container and adapted to be operated by iluid pressure, a valve centrally located on the piston projecting from the bottom face thereof and adapted to close the opening in the boss when the solution has been approximately discharged from the container, said valve and boss maintaining the bottom of the piston spaced from the bottom of the container, and tubular means connected with the outer end of the conduit i'or carryingr the solution off from the cylinder.
