Description: |
| Abstract:
In the applications of smoke-stacks to traction-engines it has been customary heretofore to arrange an inverted conical screen in the upper end of the stack, means being provided by which the screen could be lifted a short distance out of the stack, so as to thus leave a freer opening for the smoke when there are no sparks therein. The arrangement of the screen within the stack has been necessary, because if the screen is arranged outside the height of the stack is so materially increased that difficulty is experienced in going under trees along the road and through covered bridges and the like. With the screen inverted and entirely within the stack the draft is cut down to a very considerable extent and difficulty is experienced in burning light fuel such as straw, wood, &c. And for this reason, operators are inclined to lift the screen out of the stack, and thus run the risk of fire.
Claim:
The combination, with a smoke-stack, of a spark-arresting screen having a closed end adapted to be inserted into the upper end of the stack, one end of said screen being provided with means whereby the screen maybe arranged upon the stack with its closed end either up or down. |
