l as" WITNESSES JOSEPH HARMON, OF DULUTH, MINNESOTA.
GAS AND SMOKE CONSUMER.
To all whom it may concern:
Be it known that I, JOSEPH HARMON, a citizen of the United States, and a resident of Duluth, county of St. Louis, and State of Minnesota, have invented certain new and useful Improvements in Gas and Smoke Consumers, of which the following is a specification.
My furnace attachment is adapted for admitting air to promote combustion of smoke and gas and also for regulating the draft or escape of products of'combustion from the furnace.
The invention is embodied in a drum or cylinder attached to the side of a furnace above the grate and provided with a pivoted damper for controlling the draft and with a partition or false bottom which is spaced from the true bottom of the drum so as to form a passage way for admission of air through the apertured front end of the partition. The damper is adjusted by a chain or wire leading to an upper room or compartment.
The details of construction, arrangement and operation of parts are ashereinafter described and illustrated in the accompanying drawings in which:
Figure l-is in part a side view and in part a vertical section illustrating the practical arrangement of my improved furnace attachment; Fig. 2 is a cross section on the line 2-2 of Fig. 1; Fig. 3 is a perspective view of a tube to which the chain controlling the damper passes and with which it is the drum; Fig. 5 is a longitudinal section of the drum; and, Fig. 6 is a vertical cross section on the line 6-6 of Fig. 5. Fig. 7 is an end View of the drum.
In Fig. 1 the horizontal drum or short cylinder 1 is shown provided with a contracted end 2 which is attached to the side of a furnace a; at a point'above the grate. A pipe 3 is connected with the outer end of the drum and in practice it extends to a' flue or chimney (not shown). The drum is provided interiorly with a pivoted valshaped oscillating damper 4-see Fig. 5 and it is fixed on a horizontal shaft 5 which, as shown in Figs. 1 and 2, is provided exteriorly to the drum with a crank arm 5.
Specification of Letters Patent. 7 Patented All. 20, 1912 Application filed February 5, 1912. Serial No. 675,454.
swung upward, as shown in Fig. 5, it strikes the upper side of the drum 1 while its lower edge strikes on thepartition or false bottom 6. The latter is a sheet metal plate having a pendent front end 6 which is pro vided with a series of large openings, as shown in Fig. 4. The body of the false bottom' is inclined downward from the front to the rear of the drum and is-raised from the bottom of the latter so as to form a large passage-way through which air is admitted to the rear end of the drum, that is to say to the point 7 where the end of the drum extends obliquely upward. The false bottom 6 is detachable, and is held in due working position by means of pivoted catches 8, (see Figs. 2 and 5.) a The inner or rear portion of the drum is oval in cross section,
as shown in Fig. 7 This form, provides a' larger space beneath the rear or inner end of the false bottom '6.
A chain 9-see Figs. 1 and 2is attached to the free endof the damper crank 5 and extends upward'through the floor over the furnace compartment and through a vertical tube' 10 which, as shown best in Fig. 3, is provided at its upper end with one or more notches 10 that are adapted to re- "ceive and engage with links of the chain by which the latter may be locked and held in any adjustment required to hold the damper 4 at any angle that may be desired.
It will now be understood that by adjusting the damper in difierent positions the draft may be regulated and that if the damper be closed or set in the inclined position shown in Fig. 5, an opening t? is still left for the passage of products of combustion. It will be further understood that air admitted through the openings in the front 6 of the false bottom or partition 6 will flow upward along the inclined rear wall of the drum and thus meet the current of smoke and unconsumed gases escaping from the combustion chamber of the furnace into the drum 1 and that their combustion will be effected thereby. My improved attachment therefore effectsa great economy in the combustion of fuel as well as prevents the escape of noxious products of combustion into the air. The heat produced in the rear portion of the drum by the increased-combustion due to admission ofair supplements the function of the furnace, and avoids danger of explosion of fine coal or coal dust.
In practice I propose to utilize the tube '10 as a passageway for more than one chain or Wire. In other Words, I propose to extend other chains and Wires down through the tube and to connect them With furnace doors and draft slide 'so that they may be adjusted from an apartment above Without requiring a visit of the operator to the furnace-room.
I claim:
The'improved furnace attachment for the purpose specified, comprising a drum having inlet and escape openings for products of combustion at its ends and adjacentto the upper side of the drum, the lower rear Wall of the drum being inclined rearward and upward, a false bottom Which is spaced from the true bottom, its rear end being also space-d from the inclined rear Wall of the drum, an air opening being provided at the front end of the drum to admit air to .the passageway formed beneath the false JOSEPH HARMON.
. and described.
