Specification of Letters Patent; Patented Dec, 24,
Application fled April 18, 12. Serial No. 890,478.
To all whom it may concern:
' Be it known that I, HUco MUNZER, a citipart movement to said element as it is dislating apparatus of the kind indicated hav- 1 zen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Damper-Regulators, of which the following is a specification.
This invention relates to damper regulators for steam boilers and particularly to damper regulators of the kind wherein a body of water, interposed between the boilerwater and the moving element of the motor of the regulating apparatus, serves to implaced upon changes of pressure within the boiler.
The invention consists in a damper reguing anovel means whereby the apparatus can be adjusted to accomplish the closing action of the damper at difierent boilerpressures.
In the accompanying drawings,-Figure 1 is a front elevation of a boiler provided with the improved damper regulating apparatus, a part of the boiler being broken away, and Fig. 2 is a side elevation, partly in section, of the motor including part of the apparatus shown in ,Fig, 1.
In the drawings the steam generator shown comprises, with a furnace having a fire-door a and an ash-pit door b,a boiler c.
' to indicate the average level which is as- Part of the boiler is shown broken away sumed by the water in the boiler, (i. being the usual water column communicating with the interior of the boiler above and below said level and having the water-gage e.-
f is the smoke-pipe. g and h are dampers in the ash-pit door and the smoke-pipe, re-
. speotivelyv a D 1n Fig. 1 1s the motor. It is preferably arranged more or less above the maximum water level in the boiler, so that its m'ovingelement is subject only to the moving influence. of steam. generated in the boiler; this, however, is not essential. The preferred form of this motor is that shown in Fig. 2 where j is an upstanding pipe hav-.
ing attached to or formed on its upper end a head is to which is attached the fluted or bellows-like extensible chamber Z which is closedat its upper end and communicates Housing this chamber Z and serving to support it upright is the rigid cylinder m whose upper a fluid passing through pipe j into the cham- According as the first, or first andsecond,
closed end rests on the top of chamber 1 while its lower end carries an apertured guiding head which fits over pipe 7'. Uponj ber I it will extend the same upwardly and 9 so raise the cylinder m.
n is a suitable means, such as a chain extending over pulleys 0, for transmitting the movement of the cylinder m to the dampers 5 g and k.
The water column d has the usual waterlevel indicating means in the form of petcocks d and d. From a point between these two pet-cocks a pipe 3 is tapped into the water-column, being then extended downwardly approximately as far as the bottom of the boiler, and then upwardly, terminatin in a tubular system or structure 3' wh1ch may be thus described: 4 and 5 are two upright pipes connected atseveral elevations by the pipes 6 each having acutoff valve 7. Pipe 4 forms an extension of or may be connected with the upper end of pipe 3. Pipe 5 may be connected with the upstanding pipe 17' of the-motor through the medium of a T-joint 8. The T-jointmay 'be connected with the pipe 3 by the'pipe 9 which has a check-valve 10 opening toward pipe 3. Thus, the conductor formed by pipe 3 and parts 4, 5 and 6 is one'which is branched, having a return by-pass (9) around its branched portion.
Operation: It is not material how the water-trap formed by the downwardly rebent pipe 3 is supplied or replenished in the broad aspect of this invention; preferably,-however, and as herein shown, these.
are accomplished from the water in the boiler whose level will usually be kept above 9 that.where pipe 3 is tapped into the watercolumn; Changes of pressure in the boilerproduce flow of the water trapped in pipe 3 into or out of actuating relation to the movin element of the motor. In its flow 'towar the motor it passes from pipe 3 through pipes 4, 6 (one or more of them, as will a pear) and 5 into the motor; in its return ow it passes through by-pass 9, opening the check valve 10 in order to'do so. As the moving element of the motor moves, so the damper or dampers move toregulate the draft of the furnace, as-will be obvious.
or first, second and third valves 7 -(from 11.
the bottom) are closed, so the height to which the trapped water must be elevated before it can reach the motor is varied, in-
volving the advantage that in this way the apparatus can be adjusted to accomplish the closing action of the damper at difierent pressures. The check valve 10 causes, the proper functioning of this adjusting means of the apparatus and permits the ensuing return of the water from the motor to the pipe 3' in a way which is substantially direct and which, at once the pressure in the boiler ceases to operate to drive the trapped water relatively outwardly, leaves the moving ele-' ment of the motor to return substantially unimpeded. v
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In combination, with a boiler, a furnace v and a damper for the furnace, a damper- .regulating fluid-motor having its moving element operatively connected with the damper, a fluid conductor leading from the boiler to the motor, comprising diflerently elevated tubular branches situated between the boiler-and motor, and containing a liquid between the boiler and said branches, and a cut-off valve in each branch, substantially as described.
2. In combination, with a boiler, a furnace and a damper for the furnace, a amperregulating fluid-motor having its moving element operatively connected with the damper, a fluid conductor leading from the boiler to the motor, comprising difi'erently elevated tubular branches situated between the boiler and motor, and containing a liquid between the boiler and said branches, a cut-oil valve in each branch, said conductor having a return by-pass. extending around said branches, and a check-valve in said bypass opening away from the motor, substantially as described:
In testimony whereof I affix my signature in presence of two witnesses.
