,MEANS FOR FEEDING WATER TO BOILERS.
Specification of Letters Patent.
Patented July it, 1911.
Application filed December 5, 1910. Serial No. 595,580.
To all whom it may concern:
Be it known that I,.JonN Tnonrson, a citizen of the United States, resldlng in Little Falls, Passaic county, and Stateof New Jersey, have invented certain new and usefulImprovements in Means for Feeding fitter to Boilers; and I do hereby declare the following to be a full, clear, and exact. description of the invention, such as will ehable others skilledin the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to letters of referencemarked thercomwhich form a part of this specification.
This invention relates to means for feeding water to boilers, and particularly to such means as applied to boilers for locomotives and the'like where the feeding must be accomplished under varying conditions due to changes in the'position of the boiler, alterations in temperature of the atmosphere, etc.
In accordance with my invention, the firebox of the boiler is provided above the grate with a hollow water conducting means which extends from the front along one side thereof, across the back, and then forward along the other side thereof, the said means preferably consisting of a plate riveted to the shell of the lire-box on the inside thereof in such manner as to form a space between said plate and the shell. The water for feeding the boiler is 'l'orccd by an injector in o the said conducting means at one side thereof near the front of the lire-box and is discharged near the front of the tirebox into the boiler atthe other side of said means.
It is well-known that an injector works with the maximum ellicioncywhen it draws its supply from cold water and'dischargcs into hot water, and this is :urcomplislmd in and by my invention while at the same time the water, thoroughly heated by its being caused to circulate in close proximity to the tire, entcrsthe boiler at a temperature equal ingor.approximating that already in the boiler. Y
In the vaccompanying drawing, wherein my invention is fully illustrated, l igure 1 is a View partly in side elevation and partly in sectionshowing; the rear portion of a boiler and my improved means for lccdlllg the which forms with the shell of the inclosed fire-box c the water-leg (Z.
0 15 the fire-door and f the g ate. g is an injector to which cold water is supplied through the pipe It and which, op-
crating by the pressure of the steam in the boiler introduced into the injector through the pipe 2' connecting the injector with the boiler, discharges into a downwardly de; pending pipe Immediately over the grate and preferably below the lire-door e is arranged the aforesaid hollow conducting means lo. In the preferred ctmstruction, the said means is formed by an elongated plate Z Which is bulged or channeled lengthwise thereof and riveted along both its long edges to the shell c, the said plate extending from the front of the fire-box along one side of the latter to the rear, across the back of the tire-box, and then forward to the front thereof. The riveting may be employed'to secure the ends of the plate to the front wall of the fire-box, as shown in Fig. 2-, so that the conducting means thus produced is closed at all points except as now to be indicated.
At a point correspomling to the front part; of the tire-box and at one side thereof a sleeve m is screwed into the walls of the depending portion of the boiler shell and the lire-box. Into this sleeve is screwed. a connection n-to which the lower end of pipe is attached. At the other side of the tire box, and opposite the nipple n, a hole 0 is formed, atl'ording communication between the space of the conducting means is and the adjoining water-lee of the boiler,
Upon the engineer setting the injector to work it draws cold water from the pipe h and forces the water into the conductor A: out of th same through the opening 0 and into the boiler. The water fed to the boiler is therefore heated to a degree equaling or apn'oxilmitcly equaling that already in the boiler amhowmg to the size and torm ot the comluctin means It: and its close proximity to tho lire, this condition must always exist at times when fresh water is fed to the boiler so that the danger of explosions or of straining any of the parts or joints of the boiler, due to admitting water at a temperature sufficiently lower'than that already in the boiler to produce undue contraction is eliminated.
While my improvements are of peculiar value in connection with locomotive boilers, it will be understood that they are useful in connection with stationary boilers.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:
1. In combination, with the fire-box and the boiler, the latter extending along the sides and the back of the fire-box, a waterconducting means comprising an elongated sheet secured along both its longitudinal edges against the front and side walls of the fire-box, being spaced from said walls between said edges and having an inlet near one end thereof and anoutlet near the other end thereof, said longitudinal edges of said sheet being substantially straight and par I have hereunto set allel with each other substantially from end to end thereof, substantially as described.
2. In combination, with the fire-box and the boiler, the latter extending along the sides and the back of the fire-box, a waterallel with each other substantially from end to end thereof, and the' ends of said conducting means being closed by the back wall of the fire-box, substantially as described.
In testimony, that I claim the foregoing, I
, my hand this 3d day of December, 1910.
