IMPROVEMENT IN STOVE-PIPE VENTILATORS.
Specification forming part of Letters Patent N o. 199,620, dated January 29, 1878; application filed January 5,1878.
To all 'whom it may concern Be it known that I, EDWARD P. GORBY, of St. Louis, Missouri, have invented a new and useful Improvement in Stove-Pipe Ventilators, of which the following is a full, clear, and exact description, reference being had to the anneXed drawing, making part of this specification, in which- Figure l is a longitudinal section of the invention; Fig. 2, an elevation; and Fig. 3, a view illustrating the preferable arrangement of the invention in the escapepipe of a stove.
Similar letters refer to similar parts.
I have heretofore invented a device for ventilating an apartment, that is attached to and made part of a stove-pipe, and that is serviceable not only for the ventilation generally of the apartment containing the stove, but especially for carrying off the gas escaping from the stove into the apartment.
The device referred to consists, substantially, of an annular ilue formed within the Y pipe, and by means of a tube arranged concentrcally within the pipe. The flue extends longitudinally in the pipe, and at its lower end is connected with the apartment outside the pipe, and at its upper end with the interior of the pipe. The latter being heated by the passage of the products of combustion, the air within the annular iue is warmed, causing the air to iiow from the apartment into the flue within the pipe, and thence into the pipe. The device is measurably effective but, owing to the fact that the air entering the ue does not become sufciently heated therein before it passes into the interior of the stove-pipe, the draft of the stove is unfavorably affected, and the aim of the invention to that extent is frustrated.
To overcome the difficulty referred to is the aim of the present invention.
Referring to the drawing, A represents a joint of the escape-pipe of a stove or other vheater. B and C represent tubes, one of smaller diameter than the other, arranged concentrically within the pipe A, as shown in Fig. l, and forming thereby two annular ilues, b and c. The Hue b is closed to the interior of the pipe A by means of the flanges bl b1, but is connected with the apartment outside the pipe by means of the perforations b2, which are arranged in the pipe A opposite the lower end of the ilue, and with the flue c by means of the perforations b3, arranged in the tube B at or toward the upper end of the flue b. The ilue c, at its upper end, is closed to the interior of the stove-pipe A, but at its lower end is connected therewith, by means of the per forations c. The Jues b and c extend nearly the length of the joint A.
In operation, the heat currents, passing from the stove or heater upward through the pipe, warm the air within the ues b and c, generating a current therein, and from the apartment into the flue b, thence into the flue c, and thence into the pipe A, as indicated by the arrows, Fig. 1. The air is warmed somewhat in passing through the ue b,- but, from having to pass through the ue c before entering the pipe A, it becomes heated to such a degree as not to impair the draft of the pipe. The consequence is that the ventilation proceeds freely without in the least degree interfering with the operation of the stove.
I claim- The herein-described ventilator, consisting of the joint A, having the perforations b2, the ue b, having the perforations b3, and theflue c, having the perforations c', substantially as described and shown.
E. P. OORBY.
