APPARATUS FO R CLEANING WATER-HEATERSL' SPECIFICATION forming part of Letters Patent No. 620,231, dated February 28, 1899. Application filed April 16, 1898. Serial No. 677.863. (No model.)
To all whom 't may cocern:
Be it known that I, GEORGE JOHN DEHN, of Iron Mountain, in the county of Dickinson and State of Michigan, have in'vented certain new and useful Improvements in Apparatus for Cleaning Water-Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i
My invention relates to an improvement in apparatus for cleaning water-heaters, and more particularly to means for preventing the accumulation of lime and other foreign matter in boilers, water back or front ranges, and connecting-pipes, the object of the invention being to improve the Construction upon which Letters Patent of the United States were granted to me on the 7th day of December, 1897, and designated by No. 595,120.
With this object in View the invention consists in certain novel features of Construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the clairns.
In the accompanying drawings, Figure l is a View illustrating the application of my invention. Fig. 2 is a detail sectionalview.
A represents the tank portion of a waterback stove or range, and B a boiler having the usual pipe connection a with the waterback. Leading from the bottom of the boiler B is the usual supply-pipe b, and pipe-sections 1 2 3 connect the said supply-pipe b With the water-back. The central pipe-section 1 forms an integral part of a vessel C, and the pipe-sections 2 3 are adapted to screw onto the ends of the section 1. The upper end of the vessel C is preferably contracted in size and screw-threaded externally for the reception of similar threads in the flange of a cover 4:. A vertical pipe 5 (smaller in diameter than the feed or supply'pipe) communicates at its lower end with the pipe-section 1, and to its upper end a union-coupling 5 is Secured, said union-coupling also communicating with the interior of the vessel O, near the bottom of the latter, by means of a removable pipe 6, which extends within said vessel. A valve 7 is located within the unioncoupling 5, and the stern of this valve projects a suitable distance above the unioncoupling and is provided at its upper end with a hand-wheel 8. A vertical pipe 9 (similar in all respect-s to the pipe 5) communicates at its lower end with the pipe-section 1, being thus disposed at the opposite side of the vessel C from the pipe 5 A union-coupling 10 is Secured to the upper end of the Vertical pipe 9 and communicates therewith and also with the vessel C near the upper end of the latter. A valve 11 is located within the unioncoupling, and to the stem 12 of this valve a hand-wheel 13 is Secured. The vessel C is provided at its lower end with a drain-cock 14:, by means of which the contents of the vessel can be discharged therefrom when desired.
In using the apparatus the valves 7 and 11 must first be closed, and then a suitable compound will be placed in the vessel O and the.
cover 4: screwed on. Then upon opening the valves 7 and 11 a certain portion of water will discharge from the pipe-sections into the upper end of the vessel, where the compound will mingle with it, and this water and compound will discha'ge through the pipes 6 and 5 into the Water-back and also into the boiler, this operation only taking place when the water is in circulation.
While I have described my invention in connection with awater-back range and boiler, it it apparent that it can be used in connection with the feed-pipe of any water-heater.
My improvements are simple* in construc tion and are effectual in all respects in the performance of their functions.
Slight changes might be made in the de tails of Construction of myinvention without departing from the spirit thereof or limiting its scope, and hence I do not wish to limit myself to the precise details herein set forth.
Having f ully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In an apparatus for preventing the accumulation of foreign matter in water-heaters,the combination with a pipe-section adapted to be connected in the feed-pipe of a water-heater and a receptacle on said pipe-section and provided with a removable cover, of vertical pipes removably Secured to said pipesection and communicating therewith at respective sides of said rcceptacle, nipples at at the lower end of said receptacle, of couplings removably Secured to said receptacle and conmunicatin g therewith,a valve in each coupling, a -enovable pipe in said receptacle and communicating at one end with one of said couplings and terminating at its other end. near the bottom of the receptacle and pipes communicating with said couplings and With the first-mentioned pipo-section at respective sides of the receptacle, substantially as set forth.
In testimony Whereof I have signed this specification in the presence of two subscribing witnesses.
