NATHANIEL A. BOYNTON, OF NEW YORK, N. Y.
IMPROVEMENT IN GRATES FOR STOVES AND FURNACES.
Specification forming part of Letters Patent No. 126,777, dated May 14, 1872.
Specification of an Improvement in Furnaces, invented by NATHANIEL A. BOYNTON, of the city, county, and State of New York.
My invention relates primarily to a mode of constructing and applying the furnace-grate. which adapts it to be freed from ashes and clinkers without shaking. To this end I provide the grate with a rim or flange projecting upward from its periphery and extending around its sides and rear part, and locating it below the level of the bed-plate or the bottom of the fire-pot, the upwardly-projecting rim serving to close the space between the grate and the bed-plate or bottom of the pot, while at front an opening is left for the insertion of a slicing hook or poker and the removal of clinkers and other incombnstible matter, while the accumulated ashes fall through the grate under the slicing or stirring action. The invention further consists in the employment or use of an automatic supporting-latch in connection with a slicing-grate constituted substantially as set forth.
In the drawing, Figure 1 is a plan or top view of a grate and bed-plate illustrating my invention, showing also a fragment of the firepot. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a vertical section of parts of the bed-plate and grate, showing in elevation the latch which supports the front of the latter. Fig. 4. is a perspective view of the flanged grate detached.
A represents the fire-pot; B, the bed-plate; and, 0 the base containing the ashpit, all of which may be of any common or suitable construction. D is my improved grate, having a flange or rim, E, projecting obliquely upward from its periphery. The grate is pivoted on trunnions F F located back of its center, and is supported in front by a gravitating latch, G, which is so constructed that it will automatically catch and retain the grate when the latter is thrown up into its normal position. The construction of this latch is clearly shown in Fig. 3. It is pivoted at g, and is formed with a horizontal supporting-shoulder, 71, upon which rests the horizontal flange or lip, (1, projectin g from the front of the grate, and with an arm, 2", projecting obliquely downward, affording a convenient hold for a hook or poker, by which thelatch may be-withdrawn to allov. the grate to fall for the purpose of discharging cinders and emptying the fire-pot. At P in Fig. 2 is shown the end of a hook or poker as in the act of withdrawing the latch from the grate, the dotted lines showing the latch retracted and the grate falling. The full lines show the grate and latch in their normal positions. 7
To clear the grate of ashes, clinkers, and other refuse, a similar flat hook may be inserted in a horizontal position above the grate at the opening in front, and, being drawn over the entire upper surface of the grate, it will remove and discharge any incombustible matter more efficaciously, and with less labor and violence, than are involved in shaking a grate.
It will be observed that the application of my improved grate does not aiiect the fire-pot or bed-plate, or necessitate any change therein. The fire-pot and bed-plate remain intact, the grate being placed at a lower level, so as to give access to its upper surface from the front, at which part its upwardly-projecting rim or flange is omitted.
Claims.
I claim as my invention-,- 1. A grate formed with an upwardly-projecting flange or rim around-its rear and sides,
substantially as and for the purposes herein set forth.
2. A grate, D, bed-plate B, and fire-pot A, combined and arranged, substantially as herein set forth, with the said grate below the 'Witnesses:
