Description
UNITED STATES PATENT @rrron.
JAMES WITHINGTON, OF BLOSSBURG, PENNSYLVANIA.
IMPROVEMENT IN FURNACE-GRATES.
Specification forming part of Letters Patent No. 142,068, dated August 19, 1873 application filed March 29, 1873.
To all whom it may concern:
Be it known that I, JAMES WITHINGTON, of Blossburg, in the county of Tioga and State of Pennsylvania, have invented a new and valuable Improvement in Grates and I do hereby declare that the following is a full,
clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this specification, and to the letters and figures of reference marked thereon.
Figure 1 of the drawings is a representation of a sectional view of my invention. Fig. 2 is a-plan view of the same. Fig. 3 is a detail view.
This invention has relation to furnace-grates; and it consists in the construction and novel arrangement of the triangularshaft, andthe removable triangular grate-blocks. The object of this invention is to provide a strong angles 6 at the ends of the convex upper edge are, therefore, acute, and when the rock-shafts are operated, the clinkers are caught in the curved wedge-shaped space between the concave side of one block or set of blocks, and the acute angle of the next block or set of I blocks, and crushed.
The blocks 0 are each provided with a triangular opening, 2, by means of which they are slipped on the shafts B, a collar-like projection or flange, 'u, extending laterally from one side of each block around the opening 2, and serving to keep the blocks properly separated. The end block 0 of each set or bar is provided with an elongation, w, having a convex shoulder, s, and designed to be pivoted below said shoulder or stop to the operating-rod R.
The object of the convex surfaces and converging sides of the grate-bars is to elfect a better draft between them, and to provide for a convenient and thorough clearing out of the fine ashes and clinkers. The former will readily fall from the convex surface between the bars, and the latter, when the bars are vibrated, will be caught between the angular edge of the bar and the concave side of the adjacent bar, and crushed into small particles and forced through the opening between the bars.
What I claim as new, and desire to secure by Letters Patent, is-
The triangular grate-block O, pivoted at I about its middle-portion, and having the convex upper surface or edge 0, acute angle 6, and the concave converging side edges 01 terminating'at their lower ends, substantially as shown and described.-
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
JAMES XVITHINGTON.
