ARTHUR V. WALKER, OF MALDEN, MASSACHUSETTS.
COOKING-STOVE.
SPECIFICATION forming part of Letters Patent No. 447,548, dated March 3, 1891.
Application filed October 2, 1890. Serial No. 866,834. (No model.)
To all whom, it may concern.-
Be it known that I, ARTHUR W. WALKER,
of Malden, county of Middlesex, State of Massachusetts, have invented an Improvement in Cooking-Stoves, of which the follow ing description, in connection with the accompanying drawings is a specification, like letters and figures on the drawings representing like parts.
In the use of cooking-stoves it is frequently very desirable to have a light slow fire, which enables the heat from the coal being burned to be most economically and effectually used for baking, &c., and at the same time that the coal is saved the stove by the less amount of heat does not radiate into the room the same amount of heat as when a larger coal-space filled with burning coal in thick layers is being used.
In accordance with my invention I have devised a shaking grate, which may be quickly elevated in the fire-box whenever it is desired to decrease the efiective depth of the fire-box to burn less coal. This I have accomplished in a very simple manner by mounting the journals of the grate in bearings attached to arms of a grate-lifting rockshaft which is adapted to both slide sidewise and to also partially rotate in a long bearing at each end of the fire-box and substantially at right angles to the journals of the grate.
Figure 1 is a top or plan view of a fire-box and grate therein embodying my invention; Fig. 2, a partial longitudinal section in the line as, Fig. 1; Fig. 3, an end view of the fire box or basket, looking from the right in Fig. 1. Fig. 4 is a cross-section in the line as, Fig. 1, the said figure by dotted lines showing the grate as lifted; and Fig. 5 shows the gratelifting shaft detached.
The fire-box, composed of the end walls ab and back and front plates 0 cl, is formed as usual in cooking-stoves. The grate e, of
usual shape, has journals 6' 6 which when the grate is lifted, as will be described, slide in guideways made in the end walls. These journals rest in notched bearings ff, formed in arms f f extended laterally thereon and forming part of a grate-lifting shaft f so supported, as will be described, that it may have not only a rocking but also a lateral sliding movement, the said shaft f having, as shown, a square neck to be engaged by a lever or key, by which to move the shaft when desired. The shaft f has journals 3 4, which rest in bearing-bars g, shown as located below the fire box and grate. The journal 4 is prolonged by a crank 5 6, which is adapted to be engaged by the regular sh aking-handle, which is applied to the grate end piece 10 when the grate is to be shaken.
In Figs. 1 to 4 the full lines show the grate at the bottom of the fire pot or basket, in
which position the fire pot is of greatest ca-.
pacity. In this position the grate may be rocked or shaken, as the square shoulder 12 of the journal e is just below the end of the guide 6 If it is desired to make a smaller fire-pot fora small quick fire, the grate will be liftedinto its dotted-line position. This may be done by applying the usual handle or wrench to the end 6 of the cranked part of the grate-supporting shaft, sliding the same from its full-line position, Fig. 3, to the left, and at the same time turning the shaftf. This causes the arms f 2 f 3 to be lifted, their bearings f f, holding the journals of the grate, also rising until the grate occupies the dotted-line position shown in Fig. 4, the shaft f in its lateral or sliding movement finally arriving in position under the guide-slot and substantially vertically below the journals e 6 where it remains as long as the grate is to be kept up.
I do not broadly claim a grate adapted to be lifted vertically but prior to my invention I am not aware that any one has ever accomplished this by means substantially such as I have shown and described.
I claim 1. The combination, with the fire-pot and grate provided with journals, of a sliding and rocking shaft having laterally extended arms shaped substantially as described to re ceive and form bearings for the said grate and an elongated bearing for the said shaft and upon which it may slide, substantially as described.
2. The combination, with the fire-poi; hav- I name to this specification in the presence of iug' guides e e and the grate having its jourtwo subscribing Witnesses. HMS arranged to slide in the said guides, of a I sliding and rocking shaft having {U'IHS to re- ARTHUR \V. \VALKER. 5 eeive the journals of the grate, substantially \Vitnesses:
as described. J. H. CHURCHILL,
In testimony whereof I have signed my GEO. \V. GREGORY.
