UNiTED STATES PATENT OFFICE.
WILLIAM LINEHAN, OF CHICAGO, ILLINOIS.
DEVICE FOR FEEDING FLUID INTO BOILERS T0 PREVENT INCRUSTATION.
SPECIFICATION forming part of Letters Patent No. 225,622, dated March 16, 1880.
Application filed September 22, 1879.
,To all lwhom it may concern Be it known that I, WILLIAM LTNEHAN, of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Device for Feeding Fluid into Steam-Boilers to Prevent Incrustation, of which the following is a specication.
The obj ect of this invention is to furnish adevice for automatically feedin g the fluid for preventing incrustation into the boiler along with the feed-water, when supplied by a pump or an injector.
It consists of a reservoir for holdin g the fluid, from the bottom whereof a siphon-pipe leads to the pumpbarrel or injector at a point where the water is forced or drawn by suction into the boiler. The said Siphon-pipe is supplied with a stop-cock and check-valve, to regulate the amount supplied and to prevent back-press nre when pumping.
In the accompanying drawings, Figure l is a plan ot' my improvement. Fig. 2 is a longitudinalvertical section of the same, taken On line x of Fig. l; and Fig. 3 shows it applied to a pump-barrel.
Similar letters of reference indicate corresponding parts.
Referring to the drawings, A represents the fluid-reservoir, provided with a circular strainer, a. From the bottom of this reservoir a pipe, B, leads to a valve-chamber, b, in which is seated a puppet check-valve, c. This valvechamber is on a level with the bottom of reservoir A, and from it extends a tube, b', with a valve-chamber, C, connected with it, provided with a conical valve, d, seated in the diaphragm e. The stem of this valve projects out through a stuffing-box, e', and is provided with a hand-wheel, f, for Operating said valve d. From valve-chamber C a tube, g, extends, for connecting the device with the pump-barrel or injector, as the case may be.
The device is applied as follows: In Fig. 3 it is shown applied to a pump, C', (illustrated in dotted lines.) The tube g is connected with the pump-barrel D anywhere between the suction-valve D and discharge-valve E. The stop-cock or valve d is lifted off its seat surciently t'ar to allow the proper quantity'of the fluid to pass from the reservoir A into the boiler. `'Ihe uid is put in reservoir A, and passes down through pipe B, through valve c, thence through the tube b', valve-chamber C, to tube y, and from this tube g it enters the pump-barrel D. When the pump is drawing it lifts check-valve c from its seat, which permits the fluid to iow through to the pumpbarrel; but on the return stroke it closes the check-valve c, thus preventing back-pressure in the feeding device, and the iiuid that Hows out on the suction stroke, mingling with the water, is forced through valve E, and thence, through discharge -pipe F, into the boiler. Thus at every suction stroke ofthe pump a certain quantity (regulated by stopcoek d) is permitted to flow into the pump-barrelD, and on the return stroke it is forced into the boiler.
By this arrangement a small but sucient quantity of the anti-incrustation fluid is regularly and automatically fed to the boiler, preventing waste and acting with better eii'ect than when forced directly into the boiler in quantities. l
rIhe device is equally applicable to an injector. When used with injectors it is attached on the suction side.
I do not confine myself to the arrangement of stop-cock and check-valve shown and described herewith, as other arrangements for producing the same effects may be adopted without departing from my invention.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination, with tube g, leading to pump-barrel, of the reservoir A, the piping B, the chamber b, having valve c, and placed on a level with the bottom of reservoir A, and the chamber C, connected by tube b with chamber b, and provided with valve d, all constructed and arranged as shown, and for the purpose specified.
