IMPROVPEMENTPIN BEARING-BARS FOR RANGES, &c.

' Specification forming part of Letters Patent No. 177,577, dated May 16, 1876; application filed March 15, 1876.

To all whom it may concern t Be it known that I, NATHANIEL M. SIM- oNDs, of St. Louis, St. Louis county, State of Missouri, have invented a certain new and useful Improvement in Cooking Ranges and Stoves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

In my improvement each of the covers is supported in a separate plate, said-plates extending only to the middle of the range or stove.

My improvement consistsin supporting these plates at the middle by a bar, which is made solid from end to end, or partly solid and part- 7 1y tubular.

Figure 1 is a perspective view, showing the bearing-bar partly solid and partly tubular, the tubular part receiving air at one end of the range and discharging it at the inner end of said tubular part. Fig. 2 is a longitudinal section of the range, showing the bearing-bar solid from end to end. Fig. 3 is a top view with some of the top plates removed, showing another modification. v

The range or stove may be of any usual form, my improvement consisting only in the construction of the bearing-bar A.

In Fig. 1, the bar A has a solid portion, at, extending over one of the ovens O, and a tubular portion, a a extending over the fire-place F and overthe other oven 0. The tubular portion extends through the end E, where it is open at e, to allow the influx-of air, which traverses the Whole length of the tubular part a. a and escapes at the inner end through the orifices b, the arrangement being such that the it is subject to injury from excessive heat and 7 changes of temperature.

In the modifications shown in Fig. 3 the parts a and a are solid, and the part a over the fire-place is alone made tubular. The tubular part a receives air through a pipe, 1), extending horizontally in a transverse direction through the back, as shown in full lines,

.or through the front,-as shown in dotted lines,

or through both back and front. In this modification the air escapes from a through the orifices b b at each end, so that the air (in two currents) traverses the whole length of section a The combination oftop plates P P and bearing-bar A, said plates extending part-way across the top opening of the stove and their inner edges supported on said bar, and said bar made solid throughout the whole or a portion of its length, substantially as and for the purposes set forth.
