JOSEPH B. MILLER, OF WILKESBARRE, PENNSYLVANIA.
IMPROVEMENT IN GRATEl-BARS.
Specification formingrpart of Letters Patent No. 2l2,966, dated March 4, 1879 g application led July 20, 1878.
To all whom 'it may concern.'
Beit known that I, JOSEPH B. MILLER, of Wilkesbarre, in thc county of Luzerne an d State of Pennsylvania, have invented a new7 and valuable Improvement in Grate-Bars; and I do hereby decla-re 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 l of the drawings is a representation of a top plan of my grate. Figs. 2 and 3 are details of the same.
The nature of my invention consists in the construction and arrangement of a grate for furnaces for marine and other boilers, as will be hereinafter more fully set forth.
The annexed drawings, to which reference is iliade, fully illustrate my invent-ion.
A represents a portion of the tire-box of a boiler-furnace, and B B are the grate-bars placed in thesalne. These grate-barsaremade triangular in shape, hollow on the under sides,
and formed with grooves d a on their two in-l clined sides, and between said grooves are perforations b Z1 through the gratebars. The portions or divisions of the grate-bar having the perforations are not flush or even, but alternate higher and lower, as shown; and at suitable intervals the gratebars are on their upper sides provided with projections d.
ln the front end of the tire-box is a crossbar or hanger, C, with pockets at e for the bars to slide in and out, which cross-bar may be cast in or fastened to the boiler-front, andthe bars at this end covered with a plate, D. A similar cross-bar, with pockets and coveringplate, is arranged at the rear end of the firebox for the other ends of the grate-bars. In the center the bars are supported by one or more cr0ss-bars, f.
Every alternate grate-bar is made stationary in its supports, while the other alternate bars are movable lengthwise. These movable bars are at their forward ends, by rods h, connected with short arms t on a rocking shaft, G, provided with a lever, H.
The rods h pass through the front of the firebox, and the shaft G is located at the front thereof. By the use of the lever H, the sha-ft G can .be rocked in its bearings so as to move the alternate grate-bars back and forth.
By the construction of the grate-bars they are kept cool and prevented from bending or warping. Ihe movable bars are easily operated back and forth, and the projections d on them crush the cindcrs and remove all ashes and cinders.
Vith my invention the fire can be cleaned out without opening the furnace-door, and hence there is no rush of cold air in under the boilers, which is a great advantage in the proper working of a steam-boiler.
What I claim as new, and desire to secure by Letters Patent, is-
The triangular hollow grate-bars B, provided with grooves a, perforations b, and projections d, substantially as and for the purpose herein set forth.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two'witnesses. l
JOSEPH B. MILLER.
