FREDFIRICK C. FARNSWORTH, OF BROOKLYN, NEW YORK.

COMBINED RECEIVING-TANK AND PUMP-GOVERNOR.

To all whom it may concern:

Be it known that I, F nnnnnrox C. FAnNswon'rri, a citizen of the United States, and resident of Brooklyn, county of Kings, and State of New York, have invented an Improvement in Combined Receiving-Tanks and Pump-Governors, of which the following is a specification.

My invention. relates to means for collecting and measuring water, and which is also adapted to operate to control its delivery.

.he object of my invention is to provide a suitable collecting and delivery apparatus for water of condensation or feed water, which shall. be positive in action, rapid in operation, and free from all delicate mechanism, stufling boxes, packing or small controlled passages, which are liable to clog or otherwise prove defective. It has for a further object to provide an apparatus for measuring the water handled either under pressure or by gravity, said operation of measuring being positively and accurately accomplished and registered automatically as the water is delivered by the apparatus during its operation.

It has for a further object to provide a pump governing mechanism controlled and regulated by the water to be handled, whereby the pump may be operated commensurately with the presence of the water collecting, the water being automatically pumped at intervals from the COllQCtllig apparatus to a boiler or other receptacle.

My invention also comprehends the features of construction for accomplishing the above specified objects, said construction being fully described hereinafter and defined in the claims.

In the drawings: Figure 1 is a plan of a measuring apparatus embodying my invention with the tank portionshown in dotted lines; Fig. 2 represents a side elevation of the apparatus with a portion of the tank broken away to show the interior construction; Fig. 3 represents a section on the line --23 of Fig. 1; and Fig.4 represents a side elevation of a modified form of apparatus, with a portion broken away.

1, designating the bed for the apparatus, is provided with two pedestals or supports 2, spaced apart and adapted respectively for receiving the supply pipe 3 through which the water of condensation or any suitable water supply is led to the apparatus, and a discharge or suction pipe t connected Specification of Letters Patent.

to the pump 5. The pedestals 2 also form trunnion bearings for a suitable casting 6 having a head plate 7 secured thereto for supporting the tank 8, so that the latter is suitably supported for tilting action. The tank 8 is divided into two compartments 9 and 10, by a transverse division plate 11 which is arranged in the present instance substantially above the pivot point of the tank and is provided with an opening 12 forming an overflow communication between the two compa-rtments. The casting 6 is provided with two channels 13 and 14, the former of which has communication through the bottom of the tank with the compartment 9 while the latter similarly communicates with the compartment 10. The chan nel 13 is, furthermore, connected by a flexible conduit 15 with a valve 16 located in the supply pipe 13, this valve 16 being controlled by a lever 17 connected at one end to the valve stem and at the opposite end to a suitable fixture 18 secured to the tank 8 in such a manner as to cause the valve 16 to be either opened or closed as the tank moves from one position to another. The channel 14 is connected by the flexible conduit 19to the suction pipe 4 and serves to convey the contents of the compartment 10 to the pump and thence to the boiler 20 by way of the pump discharge pipe 21. The pump is operated by steam under pressure supplied by the steam pipe 22, said supply being gov erned by a. valve 23 which is automatically actuated by the pivoted lever 24 from the connection 25 fixed to the tank 8. In connection with the'mounting of the tank 8 it will be noted, the division plate 11 is so located. that the compartment 10 is longer than the compartment 9, and therefore when it is filled to a certain height, by the water overflowing from the compartment 9, it will overbalance the weight of the contents in the compartment 9 and cause the tank to tilt, thus operating the valves 16 and 23 in the required manner to admit steam to the pump and simultaneously out off the supply of condensed water. In order to regulate this tilting action and more definitely control the measured quantity of liquid which connected to the tank or its adjuncts so that each movement of the tank causes the said arm to operate and register every tilting movement of the tank, whereby the total quantity of water discharged may be determined. 29 and 30 designate, respectively, stops .located at the respective ends of the 'ank S to limit the tilting action of the tank, the one preferably being shorter than the other for the purpose of permitting proper tilting nmvcment.

it will be obseiwed that the suction pipe l to the pump is provided with a valve 33, preferably adjacent to the tank and that this valve is operated by a lever and link 35 having connection with the tank, so that as the tank tilts downward at the right hand end in Fig. 2, the valve 33 will be opened, and his at the same time that the water valve 16 is closed and steam valve 23 is opened. Now, while I prefer to employ this valve in the suction pipe l to the pump in all cases, it is not at all essential, especially where the pump is delivering against a relatively high pressure, in the other hand, where the apparatus is delivering against a very low pressure, not exceeding that of the water supply, the use of this valve prevents the water leaving the compartment 10 until the tank has been tilted. In this latter case the valve 33 insures accurate measured quantities f the water to be registered, whereas if there was no valve employed the water pressure in the tank 1t might cause quantities of water to escape through the valves 01 the pump without being measured and registered. Hence, while I prefer in all cases to provide both valves 23 and 33, the latter may be omitted when desired, namely, in those cases where the discharge pipe at has a pressure on its outlet side suilicient to prevent flow of water by gravity or the pressure of the water in compartment 10.

in Fig. l l have shown a modified construction wherein the compartment 9 is reduced substantially to a conduit constituting a rcceiv 1g chamber 31. This chamber 31 is su itlally an inlet conduit in which condensation passes prior to the water ()1. its discharge into the compartment 10. In

tom). the counterweight 9.6 is necdflheavier than that shown in the preferred form in. order to properly counterweight the tank 8. 32 designates an air Vent which may be normally open, as will be understood. in this figure l have omitted the valve 33 in the pipe l, by way of example and as illustrating that in some cases it may be dispensed with.

it will be noted that the compartment 10 in either form of the apparatus is somewhat longer than the compartment 9, so that a normally greater leverage is exerted while receiving water of condensation whereby the tank will 'lreely tilt to lower the compartment 10 in the desired. manner. In the operation of the apparatus it will also be seen that this tilting of the tank alternately opens and closes the valve 16 on the one hand and the valves 23 and 33 on the other. In normal position, as shown in Fig. 2, the valve 16 will be open to admit water of condensation into the compartment 9 either under pressure or by gravity, while the valves 23 and 2:33 will be closed. The overflow through the opening 12 into the compartment 10 gradually fills this latter compartment to the required level to overbalance the weight of water in compartment 9 plus the counterweight 26, and the tank then automatically tilts and lowers the free end. This action closes the valve 16 to cut oil the water supply, but opens the control valve 23 to admit steam to the pump. The pump thereupon comes into action and removes an amount of the collected water in compartment 10 corresponding to the desired measured quantity which is determined by the water content of compartment 9 modified by adjustment of the counterweight llpon the removal of the water from the compartment 10 the tank tilts to its normal position, closing the valves 23 and 33 and opening the valve 16, so that the operation may be repeated. If desired, the counterweight may be omitted, but its use is advantageous when great accuracy is required in having the water measured exactly registered by the registering mechanism 27.

Furthermore, the lowering of the tank to discharging position actuates the registering mechanism 27 so that an accurate register may be kept of the quantity of collected and discharged water.

It will further be apparent, that since all of the parts are proportioned to operate positively in a definite manner and all ports and passages are of comparatively large size, there is practically no possibility of the same clogging or becoming defective in their operation. In addition, it will be noted that I have dispensed with all float mechanism, stalling boxes, packing or other means which require delicate adjustment or manipulation, and consequently my improved collecting and measuring apparatus is easily installed, easily kept in order, and very positive in operation.

From the foregoing description of the operation of the device it will be seen that the pump is governed to intermittently come into operation and withdraw a quantity of the collected water from the compartn'ient 10. In addition there is also an intermittent actuation of the valves controlling the supply and discharge of the water to and from the tank, so arranged as to entirely out off the supply when the pump is in operation and vice versa, thereby making it possible to discharge a measured or definite quantity of the collected water at each operation of the tank and pump. In some cases the pump may be dispensed with, as where the discharge from compartment 10 takes place by gravity, and in such cases the valve 23 would be dispensed with.

It will now be apparent that I have devised a novel and useful construction which embodies the features of M vantage enumerated as desirable, and while I have in the present instance shown and described the preferred embodiment thereof which has con found in practice to give satisfactory and reliable results, it is to be understood that I do not restrict myself to the details, as the same are susceptible of modification in various particulars without departing from the spirit or scope of the invention.
