FRANK lS. BISSELL, OF PITTSBURG, PENNSYLVANIA.
Letters Patent No. 106,772, dated August 30, 1870. .;Hm
FIRE-PLACE GRATE.
The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern;
, full and exact specification ofthe same, wherein I have set forth the nature and principles oi' my said improvement, by which my invention may be distinguished from others ot'a similar class, together with such parts as I claim and desire to secure by Letters Patent.
My invention relates to that class oi' gratos commonly known as the lowdowu grate, and the nature"thereof consists in providingr a cold-air box or chamber' for the purpose of raising the bottom basket o r grating above thelevel of the hearth of the lireplace, thereby creating a receptacle into which cold air may be admitted, and obviating the serious objections heretofore urged against the ordinary low-down grate, to wit: that thevery high heat created on the level of the stone or marble hearth caused the same to break or crack in pieces, and also material) y lessenng the distance between the topv rim of the arch or front of the chimney-line, (in the rear of which the smoke of said grate passes up the cl1iuniey,) -and the top of the front of the grate-basket, thus preventing the pulling out ot' smoke.
1n the accompanyingdrawing, which illustrates my invention and forms a part of the specification thereor, in which corresponding parts' are illustrated by similar letters- Figure 1 is a view in perspective, illustrating a lowdown grate of the ordinary form, with my invention applied thereto.
Figure 2 is a perspective view of the cold-air box.
Figure 3 illustrates the position oi' the cold-'air chamber and grate, above an ash-pit and cold-air due ol the ordinary form.
\Vithin the casing A is the bottom grate, B, which fsa-id bottom grate 15 is placed at the top of the coldair box C. Y
C designates the cold-air box or chamber, on the top oi' which the said bottom grate B rests, and the bottom of which is entirely open, in order that the cold air may be freely admitted or retarded from below. The said cold-air box or chamber fits closely between Lthe two ja1ns.oi` the arch or grate-iront beneath the top ot' the front oi' the grate-basket, and may be removed, when it is desirable, with the greatest facility. The said cold-air box being constantly 'supplied with cold air. (or shut oft' at pleasure,) serves to protect the hearth from the downward' radiation of heat from the grate-basket, and, by lessening the opening between the top ot' the front of the grate-basket and the top rim ofthe arch, prevents thejputiiug out of smoke.
Having thus described the construction and operation ot' myinvention,
I claim and desire to secure by Letters Patent- The combination of casing A, grate-basket B, and cold-air chamber O, when constructed and operating as described. L
In testimony that I claim the foregoing, 1 have hereunto set my hand this 30th day ot' April, 1870. FRANK S. BISSELL.
