JAMES WILL SMITH, OF MOSCOW, KENTUCKY.
GRATE.
SPECIFICATION forming part of Letters Patent No. 518,470, dated April 17, 1894:. Application filed my 22, 1893. Serial No. 481.189. (No model.)
To all whom it may concern.-
Be it known that 1, JAMES WILL SMITH, of Moscow, in the county of Hickman and State of Kentucky, have invented a new and Improved Grate, of which the following is a full, clear, and exact description.
The object of the invention is to provide a new and improved furnace grate, which is simple and durable in construction, very ef fective in operation, and arranged to force the air directly into the fire, so as to highly heat the air before the same enters the boiler flues, thus also insuring proper draft in the boiler fines.
The invention consists of a grate head in sections, each section having solid ends, and longitudinally extending bars, integral with the ends, each bar being formed on the top with a deep longitudinally extending groove for the passage of air.
The invention also consists of certain parts and details and combinations of the same, as will be hereinafterdescribed and then pointed out in the claim.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figurelis a plan view of the improvement. Fig. 2 is a longitudinal section of the same on theline 22 of Fig. 1; and Fig. 3 is a transverse section of the same on the line 33 of Fig. 1.
The improved grate is provided with the two side sections A and A, and one or more middle sections A arranged between the side sectionsA and A. Each of the grate sections is provided with a series of longitudinally extending bars A formed integral with the solid ends A of the respective sections, each bar being provided on top with a deep groove or channel A terminating in the heads A of the corresponding sections. The under side of each bar A is reinforced bya longitudinallyextending rib A, the several ribs of one section being connected at their ends with transverse bars A formed integral on the respective end A of the corresponding section. The solid sides of the side sections A and A are. reinforced on their under side by longitudinally-extending ribs A likewise integral with the said solid sides A. It is understood that the several parts of each section are cast in one solid piece, so that all the parts are integral one with the other.
A grate constructedinthis manner will permit a ready entrance of the air between the several bars, the air also passing into the grooves A so as to penetrate the fuel in all its parts and thus aid combustion and also heat a large quantity of the entering air to a high degree before the air passes to the boiler. As the highly heated air travels at a considerable velocity through the boiler fines, proper draft is established in the said boiler.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The herein described grate, consisting of the side sections A A, having solid ends and sides A A and the middle section A having solid ends A the sections being provided with the bars A integral with the ends and having longitudinal grooves A in their upper surfaces, the depending ribs A A on the lower surfaces of the bars A and sides A respectively, and the transversebars A' on the under side of 'the ends A and integral with the ribs A A as set forth.
JAMES WILL SMITH.
