DAVID MATTHEW, OF PRAIRIE DU CHIEN, WISCONSIN.
Letters Patent No.A 72,309, dated December 17, 1867. 4 i
IMPROVEMENT IN PROTEGTING STEAM-BOILERS PROM GORROSION.
TO ALL WHOM IT MAY CONCERN:
Be it known that I, DAVID MATTHEW, of Prairie du Chien, in the county of Crawford, and State of Wisecnsin, have invented a Device for Protecting Steam-Boilers from Corrosion; andy I' do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specicatiomin whichi Y Figure 1 is a perspective view of a well-known form of steam-boiler, with a portion of itsy shell broken away to show the improved protecting-device within it.
Figure 2 is a view of the protecting-device, partly in section.
Figure 3 is a transverse section of iig. 2. l
Similar letters of reference indicate corresponding parts in the three figures.
This invention relates to an improved device, which is designed lfor protecting the metal of which steamboilers are constructed from rapid destruction, caused by the impurities of the water used in generating steam, and which Iv believe will also add to the purity and efficiency of the steam, as will be hereinafter described.
To enable others skilled in the art to understand my invention, I will describe its construction and operation:
In the accompanying drawings I have represented one mode of constructing and applying the improved -galvanic protectors, but I do not confine my invention to the precise construction ofthe device shown, as it may be modified, both in form and construction', without departing from the prineipleot` my invention; nor do I wish to be understood as making claim to a method of protecting boilers set forth in the patent numbered 30,511, nor to the plans set forth in the patents numbered 34,455 and 64,992.
The nature of my invention consists in the employment within steam-boilers of one or more devices, composed of a series of disks onplates of copper and zinc, or other equivalent metals, applied upon a rod which is pointed at its. ends or poles, and supported by lead or other suitable plates, which rest upon the shell of the boiler, and sustain the copper `and zine pile, so as to allow a free circulation of water beneath it.
In the accompanying drawings, figJQ, a a-represent a series of copper-disks, of any suitable thickness anddiameter, and having holes through their centres. b brepresent a series of zine disks, which may be equal in diameter to ther'eopper disks a, but much thicker than the latter. These disks are arranged in a pile, so that the copper and zinc will alternate, as shown, and a copper rod, c, is passed through them', the extremities of which are pointed and screw-cut, as shown. The ends ofl the pile of copper and zinc plates terminate in some comparatively soft 'metal plates or disks, d d,`of greater diameter than the intermediate disks. These heads or end pieces are bored through centrally, and slipped upon the ends ofthe rod c, after which nuts e e are applied upon the latter, and the whole screwed tightly together, forming what I shall denominate a galvanic pile.
It is obvious that the piles may be made of other metals than those, above mentioned, which are ohieiy electro-positive to the 'metal of which the boiler-shell is composed; and said piles may be made of any suitable length and any desired number of plates.
Having described my invention, what I claim as new, and desire te secure by Letters Patent, is- A galvanic pile, which is composed oi' copper and zine plates, or other metals equivalent in galvanie-proporties', applied upon a metal rod, which is provided-on its ends with supporting-disks, said pile being employed substantially in the manner and for the purposes described.
DAVID MATTHEW.
