To all whom it may concern.' I

Beit known that we, ALBERT DROUILLARD, a subject of the. King of Great Britain, residing at Windsor, Province of- Ontario, Canada, and JAMES M. TEAHEN, a citizen of the United States, residing at Detroit, in the county of Wayne andState of Michigan, have invented certain new and usefullmprovements in Water-Closet Ventilators, of which Io the following is a specicalion.

This invention relates to improvements in Water-closet ventilators for removing the foul air and gases from closetbo'wls;, and its object is to provide a device which .may be lreadily attached to any ordinary closet .without necessitating any material alteration' thereof and is adapted to be carried in stock by the trade as a iitting.

A further object is to provide a device the zo casing of which is so' made that it may be readily taken apart and also so constructed as to form a part of the Ventilating-pipe and contains the fan, motor, water-pipe, and valve therefor. It not only is very compact, but is 2 5 also light, cheap, durable, and possesses no complicated mechanism to get out of order.

An additional Object of the invention is to provide a novel 'motor having a wheel operated by a jet of water supplied at the axis of gothe wheel and acting outward upon its peripheral buckets toactuate the-wheel, it being thus peculiarly adapted for use in connection with this construction of ventilator.

To this end the invention consists in the 3 5 particular construction, arrangement, and combination of parts, all as hereinafter more fully described, and particularly pointed .out in the claims, reference being had -tof'the -accompanying drawings, in Which- A Figure 1 is a plan view of .a device embodying our invention, showing the same in position for use. Fig. 2 is a section on lthe line a o of Fig. l, showing the same on a larger scale. Fig. 3 is a section on the line b b of Fig. 2, and Fig. 4 is a side elevation of a fan and motor with-the ontercasing 20 and cap 15 removed.

As shown in the drawings, 1 is` the fanoasing, having a plate 2, forming the side of the casing, which is removable for the in- 5o sertion of the fan-wheel. 3 and is provided with a bearing 4 at its axis-for one end of the shaft 5, upon which shaft the fan is secured by having its hub internally screwthreaded to engage the screw-threaded portion 6 of said shaft. The opposite end of said shaft projects into a flanged opening7 in the side 8 of the casing, which opening is internally screw-threaded to receive the bushing 9, forming the other bearing for the shaft, 6o and on this end of said shaft is screwed a motor-wheel 10, the hub of which projects into the opening 7 and engages the shoulder 11 on the shaft, against which it is turned up hard to prevent the wheel coming loose. The

Wheel10 consists of the disk 12, provided with walls projecting 'outward from the face of said disk and curved 'eccentricalmly inward toward the axis thereof to form buckets 13. A flange 14, projecting outward from the side wall of 7o the fan-casing, forms the edge of a casing for the motor-wheel, an Opening being left at the i lower end for the escape'of water. A cap 15, secured to saidA flange, forms Ithe side of the motor casing and is provided with an in- 75 wardly-projecting rectangular chamber 16, to which is connected `tle Water-pipe 17, jetopenings 18 rbeing provided in opposite corners of said chambers, through which the water escapes and impinging upon the inwardly- 8o Vcurved buckets 12 causes the Wheel to revolve, thus revolving the fan. Y

. The side WallS of the fan-casing is provid ed with the openings-19, and on said Wall and inclosing said openings', together with the mo- 8 5 tor-casing, is a circular flange,-which is screwthreaded on its outer surface'to engage one end of an Outer casing 2,0, which is reduced at its opposite end and connected to a pipe 21, which pipe is provided with-.a flattened 9o end or mouth portion 22 to project between the seat 23 andthe riIn24 of the .,.bowh the seat being cut awayeatitsrundver side at, 25 to make room for the same; `This liat'tened end portion or mouth 22 is bent laterally to pro- 95 ject in over the side rim of the bowl, and the lower side of the mouth is provided with a downwardly-turned lip 26 to engage the inner side of the rim. The device is thus supported at one end upon the rimof the bowl, and the fan-casing 1 is provided with legs 27 for attaching the same to the wall of the room to support the device at the opposite end. The fan-casing 1 is also provided with the tangental flue 23, which is connected by a suitable packing-ring 29 to the ordinary ventilating-pipe 30, and thus the fan-casing and pipe 21 form a part of the vent-pipe to carry oft the odors and gases from the closet. The fan-casing may be made with the due 28 extending vertically, as shown, or it may extend laterally or downwardly, as circumstances require.

Inserted between the pipe 21 and its mouth portion 22 and connecting the same is a ringcasting 31, said casting being formed with a valve-casing 32, extending vertically across the ring and connecting the opposite sides thereof. In the valve-casing 32 is the upper chamber 33 and the lower chamber 34, said lower chamber being connected with the water-pipe 17, which extends longitudinally in the axis of the pipe 2l. The upper chamber is provided with a branch 35, leading out through the side of the ring, where it is provided with a socket to receive the water-supply pipe 36. Between the two chambers of the casing is a valve-seat 37, engaged by a valve 38, having a valve-stem 39 projecting downward through a stuffing-box 40 in the bottom of the valve-casing, and a spring 41 in the upper chamber presses upon the valve and holds the same to its seat, said spring being inserted in the chamber through an opening in the top thereof, closed by a screw-cap 42. It may be found expedient to make the chamber 33 air-tight to form a compressionchamber and provide the valve with a plunger to move within the chamber, so that the air when the valve is raised will be compressed and operate to depress the valve in the same manner as is done by the spring 4l. In the outer end of the branch 35 is inserted a screwplug 43 tocontrol the opening from the vsupply-pipe 36 to regulate the flow of Water, and a second plug 44 is inserted to close the outer end of the opening and conceal the plug 43.

On the bottom of the mouth-pipe 22 are downwardly extending ears 45, between which ears is pivoted the lever 46, and extending upward through an opening in said pipe is a pin 47, provided with a screw 48, having a slotted head to embrace one end of said lever, the opposite end of said lever being in engagement with the lower end of the valve-stem 39. Secured Within the cut-away portion 25 of the seat and projecting therefrom a short distance is a striker-plate 49 to engage the upper end of the pin 47 and turn the lever 46 on its pivot to open the valve 38 when the seat 23 is depressed by a person sitting upon it. The depressing of the closetseat thus automatically operates the valve 38 to admit water from the supply-pipe 17,

which conducts it to the chamber 16, Where it escapes through the openings 18 and expending its force against the buckets of the motor-wheel turns the same and passes out at the bottom of the motor-casing into the bottom of the pipe 21 and thence through the mouth 22 into the closet-bowl, the lip 26 serving to lead the Water to the rim, so that` it will not fall directly to the bottom of the bowl and make a noise. It is obvious Vthat the level' 46 may be depressed by other means than the striker-plate 49. The closet-seat hinge may be provided with an attachment to engage and operate the lever when the seat is depressed, or the lever may be operated directly by engagement with the seat.

The fan and motor being mounted upon the same shaft both are actuated by the jets of water, and a current of air is drawn in through the outer casing 20, the pipe 2l, the ring 31, and the mouth portion 22 from the bowl and is discharged through the flue 28 during the time the closet is in use, and as soon as the user rises from the seat the spring 41 will close the valve and stop the motor.

The reduced end of the outer casing 20 is connected to the pipe 21 by inserting the plain straight end of said pipe into said end a short distance and screwinga packing-ring 50 over the end of the casing to force the packing therein into contact with the surface of the pipe and make a tight joint. The chamber 16 is connected to the pipe 17 in like manner by the packing-ring 5l, so that in case the motor or jet-openings become clogged the casing 2O may be unscrewed from its iiange in the fan-casing and slipped longitudinally on the pipe 21 to allow access to the motor-casing, the cap 15 of which is then disconnected and moved longitudinally on the pipe 17, the end of said pipe projecting into the chamber 16, thus exposing the interior of the wheel and the jet-openings. If sediment has collected in the chamber 16, it may be easily removed by unscrewing the packing-ring 5l.

By this construction a very compact device presenting a neat appearanceis secured having all of its operating parts inclosed Within the casing of the device,4 which casing forms a continuation of the Ventilating-pipe land also forms a conduit to conduct the water from the motor back into the bowl, therebeing no chance for leakage around the valve of the Water-supply pipe.
