SPECIFICATION formingpart of Letters Patent No. 245.078, dated August 2, 1881,

Application filed April 19, 1880. (No model.)

tion of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being bad to the accompanying drawings, which form part of this specification. I

My invention relates to chimney-caps, its

object being to provide a cap of such construction that all indrafts will be avoided and the smoke freelyconducted to the outer air.

The inventionconsists in the combinations of parts hereinafter described.

In the drawings, Figure l is a vertical section of a chimney-cap constructed in accordance with my invention, and Fig. 2 is a horizontal section on the line 3 y of Fig. '1. y

A represents a hollow cylindrical chamber or stand provided with cone-shaped ends .0, the upper end being closed and the lower one open and securely connected with a smoke flue or pipe, I. The chamber A is provided at each of its sides with slots B, forming exits for the smoke. These slots are provided with covers or shields D provided with ends E, the latter being secured to the chamber, thusforming smoke-passages F between the chamber A and the shield D. The sides of these shields are open to form an exit, G, for the smoke-currents.

It will be seen that the smoke-flue I is of a much less diameter than the cone 0, and thus the downward draft incident to chimney-tops where the flue and the top are of about an equal diameter is avoided.

The shields D, as shown, are attached some distance above and below the slots B, and owing to their arrangement-one on each side of the chamber A-currents of air are prevented from entering said chamber; but the air-currents, when they strike the top, will pass through two of the spaces F, and by reason of the velocity of such currents the smoke accumulated in the chamber A will be more readily drawn out, and all indraft is avoided.

It will be apparent that my improvement is not only applicable to ordinary chimneys, but may also be applied to the smoke-stacks of locomotives or steamboats.

I claim--- The combination, with the fiuc I, of the chamber A, having ends (J, smoke-exits B, and

shields D, substantially as set forth.

- In testimony that I claim the foregoing I have hereunto set my hand this 6th day of March, 1880.
