THOMAS 1W. L. MURRAY, OF NEVBERN, TENNESSEE.
STOVEPIPE-VENTILATOR.
SPECFICATION forming part of Letters Patent No. 702,879, dated J une 17, 1902.
Application filed October 9, 1901. Serial No. 78,065. (N0 IJlOdeL) To all wit/mt t may concern.-
Beitknown thatl, THOMAS W. L. MURRAY, residing at Neu/bern, in the county of Dyer and State of Tennessee, have invented a new and Improved Ventilator, of which the following is a specication.
This invention relates more particularly to that type of ventilators cooperatively used in connection with smoke-lines and the smokeofftake pipes that discharge into the iiues; and primarily my invention seeks to provide a ventilator of this character of a very simple and inexpensive nature which presents a neat appearance and effectively serves for its intended purposes.
Hy invention comprehends a cast-metal headpiece having an internal and external rim and intervening skeleton or air-inlet portion, a sheet-metal sleeve or pipe receiving section connected with the inner rim of the hcadpiece, and a conical casing surrounding the inner sleeve or pipe receiving section having an air-tight connection with the said sleeve at the inner or reduced end and joined with the outer iiange of the headpiece, whereby an air-space is provided around the forward end of the sleeve, the inner sleeve or pipe receiving portion having means for limiting the inward thrust of thepipe to be entered therein from the head end, and openings at a point beyond said means to provide for the free escape of the air that enters into the airpspace through the head out into the iiue.
In its more subordinate features my invention consists in certain novel details of construction and peculiar combination of parts, all of which will hereinafter be fully described, and particularly pointed out in the appended claim, reference being had to the accompanying drawings, in which- Figure l is a View ofvmy improved ventilator as in use. Fig. 2 is a vertical section of a partly-constructed iiue, illustrating the purpose of the supporting or side straps. Fig. 3 is a section of the flue and the ventilator. Fig. t is a cross-section on the line 4t It of Fig. 3, and Fig. 5 is a perspective view of the ventilator.
My form of ventilator is especially designed for use at the bottom of a iiue, as shown in Figs. 2 and 3; but it may-also be conveniently used to enter the flue when in a horizontal position, it being designed to surround and receive that end of the pipe near the ceiling and which is usually the hottest.
In the drawings, in which like characters indicate like parts in all the iigures, A designates a cast-metal headpiece comprising an outer annular rim 1 and an inner rim l and an intermediate open skeleton portion lb to provide for a free air-passage between the two rims l and la for a purpose presently explained, and the outer edge of the said headpiece A is extended to forni an annular flange lc to engage with the adjacent edge of the line-opening in which the ventilator is iitted to hold said ventilator from being inserted too far into said opening.
B designates a tubular sleeve or pipe section of a diameter approximately that of the inner rim l of the head A, the lower end of which has a-turned-out flange b' to engage the outer face of the head A, as clearly shown in Fig. 3, and' the opposite end of the sleeve B has a similar outturned flange b2, the reason for which will presently appear.
C designates a conical cylindrical casing or sleeve, the outer end of which is of a diameter to snugly engage the outer rim l of the head A, and its inner or opposite end is of a diameter to snugly lie against the pipe-section B, to which .it is made fast by rivets b at a point near its inner end, as shown. By making the member C cone-shaped an air-space kis provided about the pipe or sleeve B, which gradually diminishes in area from the entrant end lb to the point` where the two members B and C are joined. This not alone provides a cooling-space around the sleeve where the smokepipe engages it, but also provides for a forced circulation or draft of airfroin the room toward the inner end of the sleeve and out into the flue, the latter result being provided for by forming a number of air-inlets b3 in the sleeve B near theinner end thereof, as shown clearly in Figs. 3 and 4. yThe inlets b3 are made by cutting the sleeve B in such manner as to permit the cut portions being turned downward,
as best shown in Fig. 3, and the turned-down' portions act as stops to limit the inward thrust of the smoke-pipe to prevent said pipe kfrom being pushed in over the air passages or inlets b3.
ICO
The inner and outer members B and C are of sheet metal, preferably galvanized iron, and to provide for holding the ventilator in place when building the flue it has two or more oppositely-disposed sheet-metal members or arms D, riveted at the lower end to the member C, the arms being utilized to support the ventilator on the partly-made surrounding lue, as shown in Fig. 2. In completing the fine the same is built close up to the ventilator, and by reason thereof the flange b2 Will also be embedded in the nue-Wall and serve as a means for supportin g the ventilator in place.
While I have described my ventilator as applied for use in a vertical iiue, it is obvious the same may also be used in a horizontal position or as a protecting-sleeve and ventilator for joining the ends of offtake-pipes When passed through floors or wooden partitions.
From the foregoing, taken in connection with the'accornpanying drawings,it is thought the advantages of my invention will readily appear. It will be noticed the same acts both as a cooling or iireproof connection for the end of the smoke-pipe that enters a line near the ceiling and a simple means for taking olf the foul air Within the room.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
The hereinbefore-described improved ventilator, comprising in combination, the castmetal headpiece A, having an inner and an outer annular rim, and intermediate air-inlets, the sleeve or pipe section B, connected at one end to the inner rim of the head A, and having an outtnrned flange b2, atits other end, said sleeve having cut portions bent back to form stops and air-inlets, the casing C, said casing being of conical shape, its large end engaging the outer rim ot' the headpiece, its smaller end being made fast to the sleeve B, at a point beyond its air-inlets, and the members D, on the casing C, all being arranged substantially as shown and for the purposes described.
