IMPROVEMENT 11v STOVE-PIPES.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.-

Be it known that I, J osnrn W. Barns, of St. Paul, in the county of Ramsey, and in the State of M innesota, have invented certain new and useful Improvements in Stove-Pipes; and do hereby declare that the following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and re-the letters of reference marked thereon.

This invention has for its object the converting of a horizontal draught into a perpendicular, or vice term.

The difficulty with the most of chimneys is, that the horizontal and perpendicular currents strike each other and cause a collision.

My improvement is so arranged, that when the two currents come together, they are going the same way,

thus helping the draught of both; and

It consists in so constructing the joint of the pipe that goes into the chimney, also in the T or connectionpipe, that such an object may be accomplished.

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 drawings, which form a part of this specification, and in which Figure-1 is a longitudinal vertical section of a T or connection-pipe with my improvement attached;

Figure 2 is a front view of the same; and

Figure 3 is a longitudinal vertical section of the end of a stove-pipe, of my construction, that goes into the chimney. V

A represents the end of a stove-pipe that is inserted into a chimney-flue, B.

The end of this pipe is closed, being of the inclined or slanting shape shown in fig. 3, so that the upper edge of the pipe enters farther into the flue than the lower.

At the upper inner edge, the stove-pipe A is cut open, as shown in that figure, leaving the end-plate O proj ccting upward.

When the smoke, 860., from the stove, passes through thepipe, if stikes the inclined end-plate O,which changes its direction from horizontal to perpendicular, when it passes up into the chimney through the opening D.

It will be seen that the currents from the stove-pipe A, and from the flue B, when they strike each other. are going in the same direction.

In a T or connection-pipe, as represented in figs. .i' and 2, I attach, in the main pipe E, a curved plate, F, opposite to the end of the side pipe G.

The plate F is so placed that the curved part thereof extends below the lower edge of the side pipe, and the plate extends far enough up to allow the current from the side pipe to change before it strikes the current from the main pipe, the two currents, at the point and time of joining, moving in the same direction.

I do not confine myself to any particular mode or manner of attaching the plate F, as that may be done in any manner desired. r

' By this improvement I give every stove a separate draught, clear through the building, even if of con siderable height, as perfect a draught as a stove would have in a one-story building, preventing the interference of the draught from one stove with that from the other, or, rather, the draught from the stoves above interfering with the draught of the stoves in the stories below, giving a perfect draught to the fines, also to-the stove-pipes throughout the building.

f In the drawings'I haveonly shown my method of changing a horizontal current to a perpendicular, but it is clear that a perpendicular current may, in like manner, be changed to a horizontal.

Having thus fully described my invention,

What I claim as new, and desire to secure by Let ers Patent, is

1. Oonvertin g the horizontal draught of a stove-pipe into a perpendicular, or a perpendicular draught into a horizontal, substantially as and for the purposes herein set forth. I

2. Constructing the end of a stove-pipe, where it joins the chimney-flue or main pipe, in, such a manner that the current from said stove-pipe may be changed, and the two currents, at the time when they join each other, may be moving in the same direction, substa'ntially as herein set forth.

In testimony that I claim the foregoing, I have hereunto set my hand, this 9th day of January, 1869.

J. W. BATES. Witnesses:

DAVID SANFORD, HARRY HILL.
