COMBINATION' FLUID-FLOW METER.
Specification of Letters Patent.
Patented Dec. 22, 1914,
Application led October 9, 1912. Serial No. 724,736.
To all whom it may concern: I
Be it known that I JAMES WILKINSON, a citizen of the United tates, residin at Boston, county of Su'olk, State o Massachusetts, have invented certain new and useful Im rovements in Combination Fluid- Flow eters, of which the following is a specification.
This invention relates to meters for indicatin the flow of fluid through a cnduit, and lts object is to provide an instrument which shows in parallel columns the quantity of water supplied hourly to a steam boiler, and the quantity of steam generated hourly b said boiler. The advantage of havin t ese two facts displayed in proximity 1s, that. the fireman can see at a single lance whether the water is being fed at too igh or too low a rate and whether the boiler is makin too much or too little steam, and can regu ate the water and the lire accord-- ingly. In a boiler room containing a battery of boilers the meters will all be located l on the same level, so that they can all be readkand compared from either end of the rooin and the fires can be properly handled to keep the input of water and the out ut of steam as nearly uniform aspossible or all the boilers.
In the accompanying drawings, Figure 1 is a side elevation of one of my combination meters; Fig. 2 is a front View of the same; Fig. 3 is an end view of a boiler rovided with such a meter; and Fig. 4 is a iagrammatic view showing in perspective a battery of five boilers so equipped.
l A bracket 1 projects from the front of the boiler and supports side by side two Utubes or their equivalent, in which are masses of mercury or the like whose level in the legs of said tubes can be varied by duid pressure. The tubes are contained in a casing 2 which has glazed openings 3 3 in its sides so that the* level of the mercryiwor its equivalent can be read by means of suitable graduation marks 5 on the Walls of the casing adjacent to said openings.
The spaces above the mercury in the two legs of one tube are connected by pipes 6 with the leading and trailing faces of a pressure dierence device, such as a nozzle plug 7 inserted in the feed water pipe 8 of the boiler and responding to changes in the velocity of flow o the water.. The other tube is similarly connected by pipes 9 with down the entire row and see just how each boiler is behaving in relation to the others,
and what proportion of their common load it is carr ing). Thus in Fig'. 4, the water feed rate or oiler 12 is too high and should be reduced, because its steam HOW iS all right Boiler 13 shows correct conditions for both water and steam. The water feed for boiler 14 is all right, but the rate of steaming is too low, probably owing to a low tire, which calls for attention from the fireman. Boiler l5 is doingall right. At boilerl A16, the water feed rate is too low, which has raised the rate of steaming too high, requiring more water, or a lowering of the lire, or both. The combination flow meter is therefore a valuable instrument for enabling the liremen to keep their boilers in a condition of hi hest eiiiciency.
n accordance with the provisions lof the patent statutes, I have described the princi-v ple of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof` but I desire to have it understood that the apparatus shown is only illustrative and that the invention can be carrie? out by other means.
What I claim as ne by Letters Patent of the United States, is
1. The combination with a steam boiler, of a combination meterl therefor, comprising a casing having openin s therein, two-U,t11be manometers associate with the casing, the indicating legs of which are visible through said YVopenings, a flow responsive device'm the feed water pi e, a flow responsive device in the steam main of the boiler, and pi es connecting each of the dow responsive evices to a corresponding manometer.
2. The combination with a battery of boilers,vof a combination meter for each boiler, comprisinga casing having openings in its sides, two
casing whosevariations in level are visibleand desire to secure loo through said openings, and flow-res Aonsive devices in -the feed Water pipe an steam main' of said boiler connected respectively* vwith said two columns.
. taining two adjacent receptacles, both contalmng Huid, a vmeans lassociated with the main and responsive to variations in the t rateof How of vapor from the boiler to cause movement of the fluid in one receptacle, and a second, means associated with the condult and responsive to variations 1n the rate of flow of liquid to the boiler to cause move- 15 ment of the Huid in the other receptacle.
In witness whereof l 'have hereunto set my hand this 8th day of October, 1912.
