STOVE OR RANGE.

SPECIFICATION forming part of lLetters Patent No. 449,918, dated April '7, 18.91. i

Application filed March l0l 1890. Serial No. 343|289. (No model.

To all whom t may concern:

Be it known that I, CLARENCE V. ROBERTS, a citizen of the United States, and aresident of Philadelphia, Pennsylvania, have invented certain Improvements in Stoves' or Ranges, of which the following is a specification.

My invention relates to that class of stoves or ranges in which a boiler is located at the back of the range and above the top plate of the same, one of theobjects of my invention being to so construct a stove or range of this character as to provide for the snug fitting of the sameintoa spacebutlittlc, if any, wider than'the rangeitself, a further object being to provide simple and effective means for causing thev circulation of water between the water-back and the elevated boiler or reservoir. These objects I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which Figure l is a perspective view of a stove or range of the class to which my invention relates, illustrating` one of the features of my invention. Fig. 2 is a sectional view, on a larger scale, illustrating the construction of the waterback and circulating-pipes. Fig. 3 isa transverse section of the water-back. Fig. 4c 1s a sectional plan view of the same; and Fig. 5 is a sectional view of part of one of the boiler-supporting brackets, with part of the boiler shown in elevation.

In Fig. 1, A represents the body of the range, and B a boiler or water-heater mounted upon end brackets D I),so as to be supported horizontally some distance above the top plate of the range. This boiler is connected by means of circulating-pipes with the waterback in the fire-box of the range, and, as usually constructed, these connecting-pipes are at the end of the'range structure and are provided with elbows whereby they are connected to the end of the boiler and the end of I nd, however, that these end connections are not essential to the proper working of the device, but that, on the contrary, circulating-pipes extending from the bottom of the boiler to the top of the Waterback serve the purpose quite as effectually, and by the use of pipes of the latter character I am enabled to locate them inside of the supporting-brackets for theboiler, instead of outside of the same, as usual, so that the range will :fit into a space of considerablyless width than a range of the usual construction, this being an import-ant feature of advantage, as ranges of this character are largely used in small houses, where the spaces between doors or between the chimn ey-breasts andthe walls, door-frames, or partitions are generally limited. The supporting-brackets for the ends of the boiler are also dished or recessed for the reception of the rows of rivets which secure the heads of the boiler, as shown in Fig. 5, so that no portion of the boiler need project beyond said brackets.

Although different arrangements of circuletting-pipes may be used in carrying out my invent-ion, I prefer those shown in Fig. 2, in which F represents the casing of a rectangular water-back having within the same a transverse partition a, forming an inverted funnel G.

From the bottom of the elevated boiler B to the top of the outer casing of the waterback extends a pipe Il, and within this pipe is a second pipe I, which extends from the top of the funnel G to a point in the boiler B above the bottom of the same. The cool water in the bottom of the boiler therefore descends through the outer pipe II and around the funnel Gr to the bottom of the water-back, and on being heated ascends through the said funnel and pipe I into the upper portion of the boiler, constant circulation between the boiler and the water-back being thus maintained. Another advantage of this construction, moreover, is that but two water-tight joints have to be formed-wiz ,those between the pipe II and the top of the water-back casing F and between said pipe and the bottom of the boiler. A central coupling J on the pipe II may, however, be used in some cases to facilitate the setting of the parts. The partition a is preferablyinclined inward from the front or fire-box side of the water-back casing to the rear of the same, as shown in Figs. 3 and 4, so that the greater portion of the descending body of water will be at the rear of the water-back and will not be heated by contact with the front of the casing until it enters the funnel G, orsuch inclination may only be at the top of the partition, if desired.

IOO

Having thus described my invention, l claim and desire to see-nre by Letters Patentl. The combination of a stove or range, the elevated boiler and the supporting-brackets therefor, a Water-back having a partition dividing it into two communicating' chambers, and circulating-pipes extending from the top of the Water-back to the boiler and located on the inside of the supporting-brackets, one of said pipes communicating with one charnber of the Water-back and the other pipe communicating with the other chamber of the same, substantially as specified.

2. The combination of the elevated boiler, 15 the water-back casing,` having a transverselyinclined partition forming an internal funnel in said water-back, a pipe connecting the boiler and water-back casing, and an internal pipe extending,` from the funnel up into the boiler, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribingr Witnesses.

CLARENCE V. ROBERTS.
