Application filed April 25,

To all whom it may concern:

Be it known that I, HARLON A. CLIFFORD, a citizen of the United States residing at Greenfield, in the county of F ranklin and State of Massachusetts, have invented a new and useful Disinfecting A paratus, of which the following is a speci cation.

This-invention relates to apparatus for use in supplying a disinfecting liquid to a column of water, the same being particularly designed for use intoilets.

One of the objects of the invention is to provide apparatus of this character which can be applied readily to a flush pipe and which will automatically deliver a portion of disinfecting fluid into said pipe while the water is flowing therethrough, the supply of disinfecting liquid being cut off, however, when the fiow of water ceases.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter dethat changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without de arting from the spirit of the invention.

11 the accompanying drawings the preferred form of the invention has been shown,

In said drawings Figure 1 is a vertical section through a portion of a flush pipe and showing the present improvements combined therewith; and

Fig. 2 is a section on line 2-2 of Fig. 1.

Referring to the figures by characters of reference 1 designates a pipe section about which is arranged a jacket 2 closed at its ends and forming an annular compartment 3 for holding a disinfecting fluid. A filling opening 4 may be provided in the top of this compartment, any suitable closure 5 being provided therefor. Arranged within the bottom portion of the compartment 3 is a valve casing 6, one end of which extends into the pipe section 1 and terminates in a downwardly extending nozzle 7. The valve casing 6 has an inlet 8 in communica-" tion with the interior of the jacket 2 and a valve seat 9 is provided within the casing 6 between this inlet 8 and the downwardly exthere from,

a I tending outlet passage 10 within the nozzle 7 A needle valve 11 is mounted within the casing 6 and the threaded end 12 thereof projects outwardly from the casing 6 and has a. head 13 whereby the valve can be adusted readily.

P1vot ally mounted within the pipe sec- U01! 1 1s a plate 14 which is substantially semi-circular and has a tongue 15 extending sa1d tongue being provided with a weight 16 which serves to hold the se mental or semi-circular plate 14 normal? pressed upwardly against the end of the nozzle 7 thus to close the outlet end of the passage 10. Thus it will be seen that even though the valve 11 is unseated, the disinfecting liquid cannot espape from the compartment 3 but willbe retained in the valve casing by the plate 14.

When water is directed downwardly through the plpe section 1 it will press agalnst the plate 14 and cause said plate to swing downwardly away from the nozzle 7 thus allowing the contents of the nozzle to escape and commingle with the downwardly flowing column of water. As soon as the downward flow stops, however, the weighted arm 15 will swing the plate 16 upwardfy to ts normal position so that it will close the nozzle 7 and prevent the further escape of the contents of the compartment 3. The amount of disinfecting liquid escaping during each operation of the plate 14 will be varied by adjusting the valve 11.

What is claimed is 1. The combination with a flush pipe and a disinfectant holder, of a valve casing in communication with the interior of the holder and having a nozzle extending into the pipe, a tiltable plate hung within the pipe, weighted means for holding the plate normally pressed against the nozzle to close the end thereof, said plate being shiftable out of normal position by the pressure of water flowing through the pipe.

2. The combination with a flush pipe and a disinfectant holder, of a valve casing in communication with the interior of the holder and having a nozzle extending, into the pipe, a tiltable plate hung within the pipe, Weighted means for holding the plate normally'pressed against the nozzle to close the end thereof, said plate being shiftable out of normal position by the pressure of or on:- i

water flowing through the pipe, and avalve within the casing for controlllng the flow of disinfectant to the nozzle.

3. The combination with a flush pipe con-- 6 stantly open for the free flow of liquid therethrough; of 'a disinfectant holder surrounding and concentric with the pipe, a valve casing within and communicating With the interior of the holder, said casing 10 projecting into the flush pipe, a nozzle extending downwardly from that end of the casing in the flush pipe, at tiltable plate hung within the flush pipe without obstructing the free fiow of water therethrough, and a weight upon the plate for holding said plate normally in position to close the nozzle, said plate being shiftable from the nozzle by the flow of water through the flush ipe, and a valve within the casing for contro ling the flow of disinfectant to the nozzle.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.

HARLON ASHLEY CLIFFORD.
