IMPROVEMENT IN BOlLER-FLUE CLEANERS.

Specification forming part of Letters Patent N o. 157,371, dated December 1, 1874; application led November 2, 1874.

To all whom it may concern:

Beit known that I, RALPH R. CARPENTER, of Tippecanoe City, in the county of Miami and State of Ohio, have invented certain new and useful Improvements in Flue-Cleaners 5 and l do hereby declare that the followin gis afull, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference markedthereon, which form part of this specification.

My invention relates to that class of steamboilers known as tubular boilers; and the nature of my invention consists in the constructionvand arrangement of a device for cleaning out the tubes or lues of the boiler by means of steam, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure l is a plan view. Fig. 2 is a rea-r end view. Fig. is a central vertical section.

A represents a horizontal steam-boiler, provided with lues or tubes B B passing longitudinally through it in any of the known and The iiues or tubes B B are arranged in a series of horizontal rows, which may be of any desired number, and any desired number of tubes or flues may be in each row. These fines or tubes often require to be cleaned, and the object of my invention is to accomplish this by blowing them out by steam from the boiler. To this end I attach a pipe, C, in the top of the boiler A near the rear end, and connect this pipe with a pipe, D, located a suitable distance in rear and to one side of the boiler, said pipe D standing in a vertical position, as shown, and iirmly secured to thewall by means of staples or hooks g g. From the pipe D extend a series of horizontal pipes, E E, across the fire-box and in rear of the boiler. The pipes E correspond in number and position with the rows of iiues in the boiler, and their outer ends are closed and supported by means of L-shaped arms a, a projecting from a bar, G, attached to the inner side of the fire-box, or they may be supported in the fire-box itself, if found convenient. From each of the pipes E extend a series of small tubes, b b, corresponding in number and position with the iiues in the boiler, so that each flue will have one of these small tubes b pointing into it, and about three inches, more or less, from its rear end. In the end of the pipe C, within the boiler A, is a valve, d, closing the end of said pipe. This valve is provided with a stem, e, which extends Vertically up through the elbow of the pipe C, and is, at its upper end, provided with a head, el. Between this head and the pipe C is a spiral spring, e2, surroundingthe valve-stem, the tendency of which spring is to draw the valve upward and close the end of the pipe. In a curved arm attached to the pipeC is pivoted a lever, H, one end of which is to bear on the head e1. From the other end of the lever H a cord should lead over suitable pulleys, so that by the engineer or ireman pulling on said rope the lever' will be turned and force the valve open. When the valve is thus opened, the steam will instantaneously rush through the pipes C D and E E, and through the small tubes b b into and through the flues ofthe boiler, thereby blowing out and cleaning the lines from all soot and dirt therein, the steam and dirt passing out at the front ends of the iiues and into the smoke-stack.

As soon as the pressure is removed from the lever, the combined action of .the spring e2 and the steam within the boiler, at once closes the valve d, and shuts oif lthe steam from the pipes. y

The pipes E E are supported in the center by means of arms h h extending horizontally from a vertical standard, I, the lower end of which is built into the iioor of the fire-box, and its upper end is bent at right angles forward nearly to the boiler, and there built into the masonry at the rear end of the boiler above the tlues. This standard with its arms will prevent the pipes E from sagging down in the what I claim as new, and desire to secure by In testimony that I claim the foregoing as' Letters Patent, ismy own I afX-lny signature in presence of The combination, with the boiler A having bwo Witnesses.
