To oZZ whom z5 may concern:

Be it known that I, WILLIAM DULLns, a citizen of the United States, and resident of Englewood, Bergen county, New Jersey, have made a certain new and useful Invention Relating to Tank-Flushing Apparatus, of which the following is a specication, taken in connection with the accompanying drawings, forming part of the same.

This invention relates especially to toilet tank flushing apparatus in which the flushing valve is connected with a tank which may be of glass and be free from openings adjacent its lower part so that during the iiushing operation the water is supplied from this tank and also simultaneously from the inlet pipe.

In the accompanying drawings, showing in a somewhat diagrammatic way several illustrative embodiments of the invention, Figure 1 is an elevation of one form of apparatus, Figs. 2, 3 and 4 are enlarged sectional views of the connections and valves thereof in different position, Fig. 5 shows another form of apparatus, and Figs. 6 and 7 are enlarged sectional views showing the valves thereof in different positions.

in the form of apparatus shown in Figs. 1 to 4, the tank 1 of heavy glass or other suitable material may be mounted in any way at the proper height above the toilet seat 2 and this tank which is preferably free from any openings adjacent its bottom portion may have cooperating therewith the siphon 6 having its shorter leg extending close to the bottom of the tank and may also have. the overflow pipe 7 connected with a' suitable overflow opening close to the top of` the tank. The valve casing 3 of brass or other suitable material has its outlet pipe 13r connected with the seatin any desired way so as to supply water thereto for iiushing` the saine. rhe si Jhon or flushing i e 6 is also connected with this valve casing .3 in

any desired way, as indicated in Fig. 1, for instance. The overiiow pipe 7 may be provided with a suitable connection 8 with which is connected the lower section 9 of the overflow pipe which, as indicated in Fig. 1, may be connected with the outlet pipe 13 adjacent the seat. The stand pipe 10 may, as indicated in Fig. 4, be connected with the connection S of the outlet pipe 7 and also with the drain passage 29 of the valve casing. rfhe regular water supply pipe 1 may: be connected with the inlet pipe or passage 5 communicating with the inlet chamber 27 of the valve casing. The inlet valve 26 of any desired form may, as indicated in Fig. 4, be located within this chamber and mounted on t-he valve stem 25, the upper end of which may project through a suitable packing in the casing and be provided with va knob or operating portion 12 for manual operation of this inlet valve when desired. The closing valve 28 may be operatively connected with this inlet valve 26 in any desired way, as by securing it on the valve stem 25 and a suitable balance valve 24 may, if desired, be provided on the lower part of this stem within the chamber 31. The fiushing valve 17 of any desired form may, as indicated, coperate with a suitable seat in the lower part of the casing so as to control access between the passage 18 communicating with the iiushing pipe 6, and the outlet pipe 13. A suitable retarding device is preferably connected with this flushing valve and may be in the form of the retarding valve 20 mounted on the valve stem 19 which also may carry the flushing valve and which may, as indicated, be guided in a suitable bearing 23 in the casing. The fiushing valve may be manually operated in any desired way as through the operating lever 4 pivoted about the pin 14 and carrying the internal operating arm 15 of this lever which may coperate with a suitable slot 16 in the stem 19 of the flushing valve.

lVhen the tank has been filled, the parts are in the positions indicated in Fig. 2, and it will be evident that on raising the op erating lever 4 the flushing valve 17 is raised from its seat as indicated in Fig. 3 and also this serves to raise through suitable means, such as the projecting portion of the valve stem 19, the cooperating inlet valve 26. Under these circumstances the water from the tank passes through the Siphon and iiushing pipe 6 and additional water is supplied through the inlet pipe 5 to be simultaneously discharged through the outlet pipe 13 which gives the desired flushing action and at the same time minimizes the size of tank required which is further minimized because it is unnecessary to use any iioat in this tank and thereby reduce its water capacity. lt/ith the valves in the position indicated in Fig. 3, the stand pipe 10 and drain passage 29 are emptied through the drain port 21 and the weight of the valves and operating lever 4 gradually closes the flushing valve 17 as the retarding chamber 32 is gradually filled with fluid through the restricted vent 22 above the retarding valve 20. There is, however, sutiicient friction in the mounting of the inlet valve 26 or its connected parts to hold this valve in open posit-ion as shown in Fig. 4, at'ter the Hushng valve is closed so that under these con ditions water from the inlet pipe 5 is supplied to fill the tank through the flushing pipe 6 as indicated. lllhen, however, the tank has been filled to such extent that water begins to discharge through the overflow pipe 7 this water enters the stand pipe 10 and iills the drain passage 29 in the casing so as to enter the closing passage 30 and thus exert pressure on top ot t-he closing valve 28. The height of the stand pipe 10 is suilicient to thus slowly close the inlet valve as the water in the chamber 31 gradually escapes through a suitable constricted relief passage 59 which may, if desired, be formed in the stem 19 so that when this filling operation is completed the valves and connections are in the condition indicated in Fig. 2.

In the form of apparatus shown in Figs. 5 to 7, the tank 1 of glass or other suitable material, may be similarly mounted and be provided with the siphon and flushing pipe 6 and with an overflow pipe 7 similarly connected adjacent the top of the tank. A suitable ioat 34 may be supported within the tank by having a suitable pivot or other bearing 35 mounted on the top of the tank or adjacent support so as to be readily accessible and make the apparatus more rc liable because free from any openings, connections or operating parts adjacent the bottom of the tank. rlhis tloat through the changing water level in the tank correspondingly operates the pivotally connected float stem 33 which may be used to operate the inlet valve supplying the tank and also supplying water to assist the discharge from the tank during the flushing operation. In this case the supply pipe 11 and inlet pipe 5 may, as indicated, be connected with a suitable valve casing comprising the connected parts 53 to which the ilushing pipe G and discharge pipe 13 are connected, and 3S in which a suitable inlet valve may be mounted. As indicated, the inlet valve may be in the form of a balanced valve having two parts 40, 41, mounted on the stem 36 having a suitable head 42 guided in the bracket 37 on the valve casing and pivoted to the float. stem 33, as indicated. rIhe connection or passage 43 serves to connect this casing 38 with the iiushing pipe G and with the connected casing 53 in which may be located a vflushing valve of any suitable description such for instance as the balanced valve having its members 45, 46, mounted on the stem 47 extending through the casing and provided with a suitable slotted yoke 51. The

operating handle or lever 50 may be pivoted to this yoke and also pivoted to t-he guiding link (50 mounted on the bracket 52 on the casing. A suitable closing lever 43 of bell crank forni may have its central pivot loosely mounted in the slotted yoke 51 and have one end pivotally connected to the link 49 on the float stem and its other end pivoted to the supporting link 61 pivotally mounted on the lower bracket 52.

lllhen the tank is iilled and the valves and connections in the position indicated in Fig. 5, the operating lever or handle 50 may be swung into the position shown in Fig. 6 to thereupon open t-he iiushing valve and allow the water from the tank to descend the flushing pipe 6 and chamber 44 so as to pass the flushing valve and be discharged through the outlet pipe 13. When the water in the tank 1 has been discharged sutiiciently the float 34 descends and raises the float stem 33 which opens the inlet valve, as indicated in Fig. 7, so that during the rst of this action the water trom the inlet pipe 5 assists in the flushing operation and then through the closing lever 4S, this same movement iinally closes the iiushing valve so that the parts are as shown in Fig. 7. '.lhereupon, the water from the inlet pipe 5 tlows past the inlet valve and up the lushing pipe 6 to iill the tank to such a point that the float 34 rises and thus lowers the float stem 33 and connected parts, closing the inlet valve and swinging the closing lever 43 to the outer end of the slotted yoke 51, as indicated in Fig. 5.
