RAYMOND L. VOSBURGH, OF ABERDEEN, WASHINGTON.

FEED-WATER HEATER.

To all whom t may concern:

Be it known that I, RAYMOND L. Vos- BURGH, a citizen of the United States, residing at Aberdeen, in the county of Ohehalis and State of Washington, have invented certain new and useful Improvements in Feed- Vater Heaters, of which the following is a speciiication, reference being had therein to the accompanying drawing.

This invention relates to a feed-water apparatus, and the object thereof is to provide an automatic device for supplying` steam boilers of high pressure engines with feed Water, which has been intimately mixed with the exhaust steam of the engine in a given inclosure or chamber.

The invention has for its further object to furnish a heater in which the distributing elements are arranged to secure the speediest utilization of a given amount of heat with the least complicated and expensive construction of apparatus.

To the accomplishment of the recited objects and others coordinate therewith, the preferred embodiment of the invention resides in that construction and arrangement of parts hereinafter described, illustrated in the accompanying drawings and embraced within the scope of the appended claims.

In said drawings F igure l is a vertical sectional view of the complete apparatus. Fig. ll is a detail perspective view of one of the distributing members, and Fig. lll is a transverse sectional view taken along lines 3h?) of Fig. I.

Like reference numerals designate corresponding parts in the drawings.

The invention involves a chamber (1), of any desired cross sectional contour having arranged therein a vertically extending pipe (2) upon which `are mounted, at certain intervals, a plurality of substantially coneshaped superimposed distributing members (3), (4), and (5), said members having their base portions disposed to form annular gutters (6), and progressively increasing in size from the topmost to the bottom member, the former having a solid apex (7) for the purpose of initially deiiecting the admixture of steam and water, as will be presently explained. The upper proximal ends of all the members are screw threaded as at (8), (9), and (10) and are adapted to engage the complementary screw threaded portions of the Specification of Letters Patent.

Application filed August 15, 1908.

vertically extending pipe (2), and at the respective points of engagement of said members with the pipe the former taper or converge downwardly in order to insure a thorough radiation of the heat through these parts. Furthermore, two of the distributing members have their upper distal ends formed to present annular recesses (11) which receive the particles of condensation. Intermediate the distributing elements are provided, preferably, two perforations (12) for the exit of the exhaust steam, and it is desired to position these exits along the entire extent of the outlet pipe (2). To prevent the eiux of the water through the outlet pipe (2) there is arranged a vertically extending cylindrical inclosure (13), the same being mounted upon the base plate (14) at the bottom of the chamber (1).

On the top of the chamber and preferably medially thereof there is connected a substantially rotund elbow pipe (15) which is common to the water inlet pipe (16) and the steam inlet oipe (17). Oonjunctively with the water inlet there is employed a conical shaped valve (18) at the extremital portion thereof, the stem (19) extending upwardly through the water inlet pipe (16) and being pivotally connected to the horizontally disposed link (20) at (21), the said link being supported intermediate its ends by a suitable U shaped or yoke member (22) and having one end connected to a vertically extending link (23), the other end having an adjustable weight (24). Communicating with the chamber (1) through the medium oi' pipes (25) and arranged adjacent and exteriorly of said chamber on the bracket (26) is a ioat chamber (27), the float (2S) being carried by the lower terminal of the vertically extending rod (23). Stuiiing boxes (30), (31), and (32) are positioned at suitable places along the connections of the water pipe (16) and the rotund elbow (15), and also at the top of the float chamber.

The numerals (34) and (35) designate, respectively, the suction and drain pipes of the chamber.

The operation of the apparatus is as followsz-Water enters pipe (16) and is atomized by the conical valve (18) and commingled with the exhaust steam from the engine which is admitted through pipe (17), this admixture being precipitated upon the cone (3) in the Vform o'l a thin sheet and ruiming over the edge oll the gutter thereof, Whereupon it drops upon the cone (4), a portion ol' the steam making its exit through perforations (12) of pipe (2) to the atmosphere. This operation is continued throughout the above steps according to the number ol'I cones employed when it falls into the lower part oi' the heater and is drawn off through the suction pipe (34) by a suitable boiler Vl'eed pump. The float (28) in chamber (27) is free to ascend or descend with the level ol' the Water, and thereby control the admission oi' water to the chamber. To exemplify, when the Water level descends, due to the action of the l'eed pump, the lloat (28) descends accordingly, pulling on bell-crank levers (20) and (29) which in turn open valve (18) thereby admits more water and maintains the proper water` level within the chamber (l). The weight (24) which is adjustable on lever (20) is provided lor counteracting water pressure on valve (18).

From the foregoing explication it will appear evident that the water in mingling with the steam and passing over the heated cones in thin sheets must become intensely heated, and it is retained in this condition for so long a time while passing through the apparatus that all o'll the metallic salts or aluminous combinations, or other i'oreign niiatter contained in the water becomes thoroughly precipitated, and are filtered out, so that nothing but pure Water is admitted to the boiler.

It should be understood that in its broader aspects my invention comprehends the employment not only of the various means described, but ol equivalent means for performing the recited functions. l/Vhile the arrangement shown is thought, at the present time, to be preferable, I desire to reserve the right to eili'ect such modifications and variations thereof as may come iairly within the scope of the appended claims.
