NATHANIEL MARTIN, OF SEAFORTH, MINNESOTA.
SPARK-ARRESTER.
Specification of Letters Patent.
Patented March 31, 1908.
Application filed April 13, 1907. Serial No. 368,066.
T 0 all whom it may concern:
Be it known that I, NATHANIEL MARTIN, a citizen of the United States, residing at Seaforth, in the county of Redwood and State of Minnesota, have invented certain new and useful Improvements in S ark-Arresters; and I do hereby declare the ollowing 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.
My invention has for'its object to provide an improved spark arrester.
To this end, my invention consists of the novel devices and combinations of devices hereinafter described and pointed out in the claims.
The invention was especially designed for use on the stacks of threshing engines, but it will be understood, of course, that the same is applicable on other smoke stacks wherever the corresponding functions are desired.
Referring to the drawings, wherein like notations indicate like parts throughout the several views; Figure 1 is a View in vertical longitudinal section through my improved spark arrester, in working position, with some parts broken away and others shown in elev,a tion. Fig. 2 is a horizontal section on the line 90 x of Fig.1 and Fig. 3 is a horizontal section on the line :0 of Fig. 1.
The body portion of the arrester is shown as made up of the flanged base plate 1 of annular form, the cap plate 2, the screen-cylinder 3 and tie rods 2' connecting the said plates, and the hinge ring 4 pivotally connected by hinge joints 6 to the base plate 1, and adapted to be secured to the upper end of the body portion 5 of the smoke stack. This hinged connection between the base plate 1 and the hinge ring 4 permits the spark arrester to be turned backward, so that the body portion 5 of the stack can deliver direct to the atmosphere, whenever so desired.
The parts so far described are of the customary construction.
The base late 1 has fixed thereto a cross bar 7 spannmg'the annular passage through the base plate. In said cross bar 7 and the cap plate 2 is mounted an upright 8 which serves as the center post of a rotary beater. To the center post 8, at the lower portion thereof, are rigidly secured a pair of cross arms 9 staggered apart from each other lengthwise of the post. To the upper portion of the post 8 are secured a pair of cross propeller blades 10 which are also staggered apart from each other lengthwise of the post. The pairs of cross arms 9 are connected to corresponding members of the propeller blades 10 by the vertical blades 11 extending lengthwise of the screen cylinder 3 and working near the inner surface thereof. The screen cylinder 3 is shown as tapped near its upper end by a cinder delivery pipe 12.
When in working position, as shown in Fig. 1, the spark arrester, of course, forms the upper end or delivery section of the smoke stack. Threshing engines, and most other engines, operate under a forced draft produced by the exhaust from the englne delivered through the stack. The gases, therefore, move outward through the delivery end of the stack, under some slight pressure. It follows, that under the actionof the gases on the ropeller blades 10, the beater, made up of the parts 8, 9, 10 and 11, as shown, wil receive a rotary motion, at a fairly rapid rate of speed. As a result, the outwardly moving gases will assume a whirling motion tending to hug the screen cylinder 3, in their progress toward the upper end of the same, and their passage outward through the meshes thereof. The rotary action of the beater, and the whirling motion of the gases,
will tend to bring the cinders into the path of the vertical blades 11 of the beater, and the cinders will be struck by these blades 11 and forced out against the screen 3 with. some violence, thereby crushing the same into small particles. Such of the cinders as are not struck and crushed by the rotary beater will be forced outward, under the combined action of the beater and the moving gases, into the delivery pipe 12 and be thereby directed to any desired place where they will be harm less, as, for example, into a vat of water. The crushing of the cinders in the arrester, of course, either deadens the spark, or so subdivides the cinder, that if any thereof pass out through the meshes of the screen 3 they will be so small and die so quickly as to be harmless.
It will be understood, of course, that the structure can be varied to a considerable extent without departing from the spirit of my invention. It should be further noted that, under the action produced by the rotary beater on the moving gases, the meshes of the screen 3 will be kept clean. By thus keeping the meshes clean, the screen will also be kept propeller blades constituting the up er porcooler, because the hot cinders will not clog tion of said rotary beater and extenc ing aptherein. proximately in line with the opening of said What I claim is cinder delivery pipe and arranged to assist In a spark arrester, the combination with in forcing the cinders into said opening, subthe screen-equipped body portion thereof stantially as described. serving as a section of a smoke stack, of?
