CARBON-CONSUMER FOE BOILERS AND THE LIKE.

Specification of Letters Patent.

Patented Feb. 20, 117.

Application filed May 6, 1915. Serial No. 26,253.

an improved means for promoting complete 7 combustion and consumption of the fuel and smoke thus conducing to economy in fuel and general efficiency in operation.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings, forming a part of this specification, and in which,

Figure 1 is a side view shown partially in section of a construction embodying my invention,

Fig. 2, a topplan view of the same,

Fig. 3, a longitudinal section taken through the same,

Fig. 4, an enlarged cross section taken on line H of Fig. 3, and

Fig. 5, an enlarged section taken onv line 5-5 of Fig. 3.

The preferred form of construction as illustrated in the drawings comprises a hollow fitting 6 arranged in an ordinary horizontally extending stove pipe 7 extending from a boiler or other heater 8 as indicated. The fitting 6 is provided in its side adjacent the boiler 8 with air passages 9 adapted to permit the escape of air therethrough into the lower portion of the stove pipe 7, in which is provided end openings 10 communicating with the lower ends of stem portions 11 of substantially T-shaped heating chambers secured to the exterior of the pipe 7. Each of the heating chambers is provided with cross arms 12 having perforations 13 in their under sides adapted to ad'- mit air therethrough. By this arrangement the air resting against the outer sides of the pipe 7 immediately under chamber portions 12 is heated and rises and enters through the perforations 13, at the same time air passing from fitting 6 through openings 9 into the lower portion of smoke pipe 7. This action is due to the fact that while the air heated against the exterior of the smoke pipe 7 is lighter than the exterior atmosphere the air within the fitting 6, although hotter than the air entering chamber portions 12 is nevertheless cooler than the smoke and flames passing upwardly through the smoke pipe so that the air 'in chamber 6 tends to flow along the bottom of pipe 7 into the boiler 01" other heater 8 thus intermingling withthe products of combustion and tending to promote complete combustion. A damperl t is pivo-tally connected with the upper side of fitting 6 and is operatively connected by means of link 15 with operating arm 16 on the cross shaft 17 in pipe 7. An operating arm 18 is secured to one end of shaft 17 outside of pipe 7 and is equipped with an adjustable weight-19 and adjusting chain 20 by means of which the damper may be secured in different adjusting positions. With this arrangement it will be observed that the weight 19 tends to normally open the damper lat but that the position of the damper may be regulated through chain 20 as will be readily understood. The damper controls the combustion in the usual manner and at the same time tends to deflect the hot flames upwardly over the fitting 6 to prevent intermingling of the air coming in through said fitting.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. A horizontal smoke pipe in combination with a hollow fitting arranged transversely in the lower portion thereof, said fitting being perforated on the side toward the ap proaching smoke and gases, means for conducting air in contact with the outer surface of said pipe to heat the same and discharge it into said fitting, a damper hingedly connected. to said fitting and means for operating said damper, substantially as described.

2. The combination with a substantially horizontally extending smoke pipe, of an air supplying chamber secured to the exterior of'said smoke pipe and in contact with the outer wall thereof throughout substantially the length of saidchamber, said chamber comprising a substantially vertical portion andasubstantially horizontal por-' tion,'the'latter being provided on its under face and adjacent the pipe with air inlet openings and the lower end of said vertical portion communicating with the interior of said smoke pipe, substantially as described.

3, The combination with a substantially horizontally extending smoke pipe, of a hollow fitting arranged in the lower portion thereof, said fitting being provided with air discharge openings onthe side toward'the approach of the smoke and with air entry openings at its ends communicating through the walls of said smoke pipe with the exterior thereof; air supplying chambers secured to the exterior of said smoke pipe, said chamber being substantially in T-form, the cross Copies. of this patent may be obtained for on the outer side of said smoke pipe; and an adjustable chain secured to the free end of said weighted arm, substantially as described.

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