ISAAC G. WATERMAN, OF SANTA BARBARA, CALIFORNIA.
AUTOMATICALLY-OPERATED FLUSHING SYSTEM FOR WATER-CLOSET BOWLS.
Specification of Letters Patent.
Patented Oct. 24, 1905.
Application filed September 9, 1903. Serial No. 172,488.
To all whom, it ntay concern.-
Be it known that I, ISAAC G. WATERMAN, a citizen of the United States, residing at Santa Barbara, in the county of Santa Barbara and State of California, haveinvented new and useful Improvements in Automatic Electrically- Operated Flushing Systems for Water-Closet Bowls,ofwhich the followingisaspecification.
This invention relates to automatic electricall y-operated flushing systems for water-closet bowls.
In the present invention my object is to provide an improved and. novel arrangement of electrically operated valves, switches, and novel automatically-acting mechanism whereby the flushing of a water-closet can be accomplished at Will and continued automatically for a predetermined time.
WVith this object in view the invention embraces certain improved features of construction and novel arrangements of parts set'forth in detail hereinafter and embraced in the appended claims. I
In the accompanying drawings, Figure 1 is a diagrammatic view of the invention; Fig. 2, a vertical section of the cylinder; Fig. 3, a vertical section taken at right angles to Fig. 2; Fig. 4, a diagrammatic view of a modified arrangement; Fig. 5, a vertical section of the cylinder and valve of Fig. 4, and Fig. 6 avertical section taken at right angles to Fig. 5.
A water-closet bowl 1 of ordinary construction is provided with a flushing-pipe 2, leading from any source of fluid-pressure. An electromagnetic valve 3 controls the flow through pipe 2 to the bowl. This valve may be of the form set forth in my application filed August 29, 1903, Serial No. 171,215. and consists of a solenoid or magnet-coil 4 on the.
pipe 2, an armature slidable within the coil or solenoid, and normallypressed in one direction bya spring 5, a rotary plug-valve 6, having a ratchet-wheel '7, and aspringpressed pawl 8, carried by the armature and adapted to engage and turn the ratchet-wheel and valve when the solenoid is energized. Alternate energizations of the solenoid open and close the valve. A dog 9 engages the ratchet-wheel and prevents backward movement thereof and of the plug-valve. the supply-pipe is an electromagnetic valve 11, similar in construction and operation to the valve 3.
Coupled to the supply-pipe 10 is a cylinder 12, having a central partition 13, which is provided with a stufling-box 14 and provides On another branch 10 of the water-compartment 15 in the lower part of the cylinder. The compartment 15 is connected at its bottom with the pipe 2 by a drain-pipe 16.
Movable in compartment 15 is a piston 17, having a rod 18 working through stuflingbox 14- and adjustahly connected to the piston by screw 19. Secured to the end of the rod 18 is a head 20. to which are pivoted the spring pressed pawls 21 and 22. A coilspring 23 tends to force the piston downwardly in compartment 15.
In the upper part of cylinder 12 is an insulating-block made in two parts 24 and 25, from which depend hangers 26, fitted in notches in the edges of the parts 24 and 25.
Journaled in the hangers 26 is a shaft 27, on Which is secured rotary switch-contacts 28 and 29, each composed of an insulating-disk 30 and an armed metal contact embedded therein. The metal contact 31 has two arms and the metal contact 32 four arms.
Secured on shaft 27 is a four-tooth ratchetwheel 33, with which the pawls 21 and 22 are adapted to engage, pawl 21 engaging therewith when the piston is raised to its limit and pawl 22 engaging with the ratchet-wheel when the piston has descended. On shaft 27 is also fastened a polygonal hub 34, with which spring-arms 35 engage to hold the rotary con-o tacts where turned. The contact-fingers 36 are arranged to be engaged by the contact 31, and the contact-fingers 37 are adapted to be engaged by the contact 32. The terminals of the contact-fingers 36 and 37 are located on the block 24, to which the circuit-wires lead.
The numeral 38 represents a switch having a rotary four-point contact 39 and ratchetwheel 40 and a spring-retracted push-button 41 and pawl 42. When the push-button is pressed in, the pawl engages the ratchet-wheel,
and when the push-button is released the' engages ratchet-wheel 33 and snaps the rotary contacts 28 and 29 a quarter-revolution, which closes valve 11 and opens valve 3. The water from pipe 2 continues to flush the Water closet bowl until the water in compartment 15 has drained therefrom, whereupon by the fall of the piston the pawl 22 engages the ratchetwheel 33 and snaps rotary contacts 28 and 29 again; but as contact 28 has only two points the circuit of valve 11 is not made. The circuit of valve 3 is made again by contact 29 and the valve in pipe 2 closed, thus concluding the flushing operation. When the switch 38 is again operated, the foregoing operations will be repeated.
Referring now to the modification shown in Figs. 4:, 5. and 6, the valve 3 and circuit connections therefor are dispensed with. In place of the two-point contact 28 a four-point contact is employed. The drain-pipe 16 leads to a packed nut 51 and communicates with a port 52, leading to the opening through the plug-valve. A by-pass 53 is made in the valve-casing and adapted to put the opening in the valve in communication with the fluidinlet pipe when the valve is closed. On operating the switch 38 the valve is opened, and communication is cut of to the compartment 15. The water continues to flow and flush the water-closet bowl until the water in compartment 15 drains out, whereupon the single pawl 22 used (pawl 21 being dispensed with) snaps the rotary contact 50, and the solenoidis then energized and the valve closed, thus stopping the flushing operation. Compartment 15 again fills, and the above-described operation can be repeated at will.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
