$PECIFIOATION forming part of Letters Patent N0. 703,762, dated July 1, 1902. Application filed October 18,1901. senate. 79,168. (No model.)

To all whom it may concern:

Be it known that we, THEODORE MONROE CARPENTER and FRE LINNEL BAKER, citizens of the United States, and residents of Los Angeles, in the county of Los Angeles and State of California, have invented a new and Improved Ventilator, of which the following is a full, clear, and exact description.

This invention relates 'to'aventilator for carrying off the impure gases from waterclosets and Various devices in sanitary plumbing. It is particularly adapted for use in connection with a flushing apparatus, audit comprises a motor driven by the water as it falls into the flush-tank, such motor operatingan exhaust-fan for carrying off the gases from the vicinity.

This specification is a specific description of one form of the invention," while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front view of the apparatus, showing it in use. Fig; 2 is a'section on the line 2 2 of Fig. 3. Fig. 3 is a plan view showing the motor, the top of the exterior casing being removed; and Fig. 4 is a section on the line 4 etof Fig. 2.

In Fig. 1, a indicates a flush-tank which is used in connection with the apparatus 1). a indicates a float which is arranged in the tank CL and carried on an arm (1*, connected to a cock or valve 0, commanding the pipe 0, through which the water-supply is led. When the water reaches the upper level in the tank a, it raises the float a, and this throws the arm a so asto close the cook a and cut off the water in the supply-pipe c.

(1 indicates a casing which is supported on the flush-tank and'also, if desired, by a chain from an overhead support. The casing d is preferably cylindrical in form and is provided at its lower part with a funnel or hood (1, adapted to receive and carry into the casing the foul gases from the apparatus Z7. Within the lower part of the casing (1 works an exhaust-fan c. The casing is formed, as best shown in Figs. 1, 3, and 4, with an outlet pipe or tube 61 for the gases drawn through the extension of the gasket f hood cl. This outlet is provided with a gate d ,which is normally closed, but is adjusted very delicately, so as to open in response to the slightest outward current within the outlet-conduit 61*.

Just above the fan 6 within the casing d is arranged a horizontal partition f, on which is mounted a stationary cone f. This cone is fitted with a centrally-located tube f provided with ball-cups working with ball-cones on a shaft g, passing centrally through the tube f Antifriction-balls are interposed between the cups and cones, and thus the shaft g is mounted to turn freely. This shaft g carries a sleeve e, adj ustably held thereon by nuts g, and to said sleeve 6' is attached the fan 6.

Within the tube f is fitted a tube f which forms, practically, a part of the tubef and between these tubes and f is arranged a tubular rubber gasket or packing f to hold the parts snugly together and reduce vibration. The tube f has at its upper end a conical hood f which fits down snugly over the cone f and has located between it and the cone f an At the lower circumferenceof the hood f is arranged an annular flange'f", which is carried on the cone f and extends upward therefrom to prevent the passage of Water onto the hood f and thusavoid the possibility of water entering between the parts f and f and leaking down into the compartment in which the fan is located.

. The upper end of the shaftg carries a motor which comprises a disk It, located over the annular flange f and having a downwardlyprojecting peripheral flange h, carrying "buckets'h against which a stream of water is continuously projected I from. the pipe 0 while the apparatus is in operation. This stream of Water turns the parts 71 h,and h andimparts a rotary movement to the shaft g, thus driving the fan. p

77, represents a water-outlet pipe passing from the base of the cone f to carry off the water used to run the motor. This pipe h empties into the flush-tank a. By the employment of the cone f and arranging the pipe 71 at the base thereof, as shown, all the water will be discharged from the casing through said pipe.

d indicates'a removable cover for the easing d, this cover lying directly over the motor.

In Fig. 3 the cover' d is supposed to have been removed.

In the operation of the device, assuming that the flush-tank is emptied by the ordinary device for that purpose, (not fully shown in the drawings,) the water will run out of the flush-tank and the float a will fall, thus opening the cook or valve 0 of the pipe 0. The water will then flow through the pipe 0 and operate the motor within the casing 01. The water flowing into engagement with the buckets k of the motor will drive the shaft 9, and this operates the fan e, thus driving off the foul gases through the outlet 01 The overflow from the motor passes by the pipe 72, into the tank a, and as the water rises in the tank it lifts the float a and when the proper level of the float has been reached the cock 0 is closed and the water is stopped from flowing through the pipe 0.

It will be observed that this apparatus util-- izes the force of the water flowing into the flush-tank to operate it and that no extra force is required. There is no waste of water, since the water used by the motor passes-into the flush-tank and is used again therein. While the invention is applicable to various sanitary purposes, it is particularly applicable to the use here illustrated, for the reasons pointed out above.

Various changes in the form, proportions, and minor details of our invention may be resorted to without departing from the spirit of our invention. Hence we consider ourselves entitled to all such variations as may lie within the scope of our claims.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. In a ventilator of the character described, a casing having an upperand lower compartment, the lower compartment having an inlet in its bottom and an outlet in its side, and the upper compartment having a conical bottom and provided with a water-supply pipe leading into the same above the bottom and a dischargerpipe leading from the bottom thereof, a vertical shaft mounted in the casing and having its ends extending into the compartments, a water-wheel mounted upon the upper end of the shaft in the upper compartment and into which the apex of the conical bottom of the upper compartment extends, said wheel being provided with peripheral buckets, and a fan mounted upon the lower ranged on top of the cone adjacent to its apex,-

a fan attached to the lower end of the shaft,
