B. W. DUNKLE E.
Grate.
No. 90,645. Patented June I, 1869.
PETERS Phom-Litlwgnphnr, Walhmglon n c aeaa B. W. DUNKLEE, 0F BOS TON, MASSACHUSETTS.
Letters Patent No. 90,645, dated June 1, 1869.
G-RATE.
The Schedule referred to in these Iuattere Patent and making part of the same.
To all whom it may concern:
Be it known that I, B. W. DUNKLEE, of Boston, in the county of Suffolk, and State of Massachusetts, have invented certain new and useful Improvements in Grates; and I do hereby declare that the followlng is a full and exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.
The nature of my invention consists in making a fire-grate in two parts, or in two series of parts with bars attached by oneend only, the bars of one part arranged to fit into the interstices between the bars of the other part; one part or series of parts being movable, while the other is stationary.
To enableothers skilled in the art to make and use my invention, I will proceed todescribe its construction and use.
- In the drawings- Figure 1 represents, in perspective, a fire-pot, containing one of my improved grates. v
Figure 2,represents a horizontal plan of the same.
Figure 3 represents the plan of the same, with one part, A, fig. 4, removed.
Figure 4 shows in plan the movable part of the grate.
In the drawings- I B, figs. 1, 2, and 3, represents the fixed portion of the grate, having bars b b b, 850., more or less tapering.
I A represents the movable portion of the grate, provided with tapering bars a a a, 8m, so arranged that they will, when desirable, fill the spaces between the harsh b, 860.
The bars 1) b, &c., do not extend entirely across the bottom of the fire-pot, but stop at a point a little past the middle, as shown in fig. 3, so that if the front portion A,.be withdrawn, a space, S, fig. 3, will be left, through which the ashes and cinder may fall.
If theportion A is partially drawn out, as represented in fig. 1, then air will: be admitted to the fuel through the spaces between the two sets of bars a a a,
800., and b b b, 860., the size of-these aiuspaces being regulated by the position of the part A; the greater portion of the air being admitted near the front and rear walls of the fire-pot, thus securing the most perfeet combustion of the fuel.
What I claim as my invention, and desire to secure by Letters Patent of the United States, is-,-
The
shown and described. 1
