Specification of Letters Patent.

Application led November 24, 1915. Serial N9. 63,223.
To all whom t may concern -Be it known that I, Rona'r L. SPURLIN, a citizen of the United States, and a resident of Tampa, in the county of Hillsborough 'and State of Florida, have invented an Improvement in Draft-Regulators, of which the following is a specification.
This invention is an improvement in steam boilers and has particular reference to a draft producing and regulating device therefor.
An object of the invention is to provide a device of this character which may be mounted in the smoke stack or funnel of the boiler and connected to a suitable source of steam supply, the device including an adjustable valve adapted, in conjunction with other parts, to create and regulate a jet of steam in the stack or funnel calculated to produce a draft of variable intensity.
Another object is the provision of novel means for adjusting the valve whereby to regulate the draft, which means consists of a rotatable shaft having a disk eccentrically mounted thereon for operating a yoke member which is connected to the valve.
The inventive idea involved is capable of receiving a variety of mechanical expressions, one of which, for the purpose of i1lustrating the invention, is shown in the accompanying drawing, in which- Figure 1 is a side elevation, partly broken away and shown in section, of the device constructed in accordance with the invention. Fig. 2 is a section on the line 2-2 of Fig. 1. Fig. 3 is an enlarged fragmentary section, similar to that illustrated in Fig. 1, showing the valve in opened position.
Referring more .particularly toA the drawing the numeral 5 indicates a horizontally arranged steam supply pipe which is adapted to be conveniently mounted in the smoke stack or funnel of a steam boiler and has connected thereto at its outer end a branch pipe 6 which leads to any suitable source of steam supply.
The inner end of the pipe 5 is mounted in a coupling 7 which, when in position, is preferably located centrally of the smoke stack. Extending upwardly in the latter is a casing 8 preferably of cylindrical formation the lower end of which is also mounted in another of the openings in the coupling 7. At the upper end of the casing 8 the same is provided with a valve Seat 9 prefer.-
ably having an interiorly tapered wall and adapted to be engaged by a similarly shaped valve 10 the stem 11 of which is mounted in a web or bearing 12 adjacent the valve seat 9. `This stem 11 extends below the lower end of the casing 8 and is also mounted in a bearing 13 adjacent the lower end of said stem. At its lower extremity the stem 11 is connected to a yoke member generally indicated by 14 and comprising upper and lower members 15 and 16, respectively, which are connected by bolts 17. The lower member 16 has extending therethrough intermediate its ends a pin' 18 adapted to engage in the socket 19 f ormed in the bottom of the coupling 7 when the valve 10 is in closing position, as shown in Fig. l.
Means are provided in connection with the yoke member 111 for vertically adjusting the valve 10 in order to move the same to opened and closed. positions and these means include a shaft or rod 20 extending longitudinally of the pipe 5 and mounted in a bearing 21 adjacent the inner end of said pipe, the outer end of said rod or shaft extending beyond the adjacent end of the pipe 5 and having preferably mounted thereon a sprocket wheel 22 on which a chain is adapted to be mounted for the purpose of rotating the shaft. The rod or lshaft 20 has eccentrically mounted upon its inner end a disk 23 which is of a diameter substantially equal to the distance between the members 15 and 16 of the yoke 14. It will thus be seen that byrotating the shaft 20 in the direction of the arrows, in Fig. 2, the valve stem 11 will be forced upwardly and thus disengage valve 10 from its seat 9 and permit the steam in the pipe 5 and casing 8 to pass beyond said valve with sufficient force and volume to create a suction in the smoke stack and thus produce a draft. It will be understood, of course, that the volume of steam passing through the valve seat may be regulated by adjusting the valve the desired distance from said seat. The coupling 7 is provided with anopening adapted to be closed by a removable plug 24 whereby access may be had to the interior of the coupling for purposes of repair.
What is claimed is:
1. A device of the character described comprising a steam supply pipe, a coupling carried by one end of said pipe, a casing mounted in said coupling and extending at right angles to said steam supply pipe, a valve seat at one end of said casing, an adjustable valve for said seat, a yoke member mounted in said coupling and connected to said valve, a shaft extending longitudinally of the interior of said supply pipe and having one end projecting into said coupling, an eccentric disk carried by the inner end of said shaft and engaging said yoke ineinber whereby the same may be raised and lowered to adjust said valve.
2. A device ofthe characteil described, comprising a horizontally arranged steam supply pipe having one end thereof adapted to project into the exhaust stack of a boiler,
