To all whom it may concern:
Be it known that I, JOHN E. RADIGAN, a citizen of the United States of America, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Controlling Devces; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.
This invention relates to regulating devices and in particular the invention relates to damper-operatingmechanism for use in connectlon with steam-generating furnaces, and has for its object to provide an im'- proved apparatus of this character which shall automatically control the generation of steam bythe pressure thereof by regulating the fire so as to increase the same when the pressure of the steam falls below a predetermined limit and to reduce the. fire when the pressure of the steam exceeds a predetermined limit. f More limitedl the object of my invention is to provide or controlling the furnace damper by means of a movable member or motor connected thereto which is subjected to the pressureof fluid tending to move the same 1n a direction to close the damper when the steam reaches Aits predetermined limit of high pressure and to automatically cut off the supply of such Huid from the -movable member when the steam pressure reaches its predetermined lower limit.
Generally speaking, the invention may be defined as consistin of the combinations of elements embodied 1n the claims hereto annexed and illustrated in the drawings forming1 part hereof whereinv igure 1 represents a front elevation of my apparatus, certain parts being shown in section; Fig. 2 represents a top plan view of said apparatus; Fi 3 represents a cen tral Sectional detail o said apparatus and Figs. 4 and 5 re resent enlarged sect1onalA detailsv of the va ve mechanism which controls the sup ly of pressure fluid to the movable mem er or motor hereinbefore referred to. A v
Describing the parts by reference characters, 1 re resents a frame, which may be a art of tlie front of a steam boiler. This iframe is provided with a centrally arranged bracket 2 having at its upper end a pair of V-sha ed lbearings 3 whereon there is supporte a beam 4, said beam being provided with a pair of knife-edge pivots 5 and 6 resting 1n the bearings 3. Beam 4 has attached to the opposite ends thereof a pair' of spherical receptacles 7 and 8 respectively, said receptacles being connected by means of a pipe 9 communicating with the bottoms thereof. Beam 4 is provided with a passageway or duct 10 which extends from the central part thereof to receptacle 8. At the central portion of the beam, this passagelway communicates with pivot 6, to whlch there is fitted a ipe 11 extendin to the boiler (n ot shown The arm of t e beam which carries the receptacle Sis provided with a threaded rod 12, which ma be formed as the bottom member of a bai the other members whereof are connected to said arm. Rod 12 extends parallel with the beam and is provided with a weight 13 threaded thereon.
14 denotes a cylinder, which is carried by the 'frame land has therein a piston 14' (shown in dotted lines, Fig. 1) provided with a piston rod l, the upper end whereof is connected to a rope or similar flexible connection 16, leading over a pulley 17 to the furnace damper (not shown). This damper may be provided with a weight which tends to open the same and, through connection 16, to lift the piston to the upper end of its cylinder. For the purpose of operating said piston in a direction to close the damper and thereafter permit the opening of the damper, I provide the followinV construction :-18 and 19 denote a pair' ofavalve casings each having therein a downwardly seating valve 20, 21, respectively, and each being provided with a downwardly tapered valve seat 22, 23, respectively, for the correspondingly tapered surface of its valve. A pipe 24, communicating with any suitable source of fluid under pressure, as a water-main, is connected to valve casing 18 above the valve seat therein. A pipe 25 connects casing 18 with casing 19, communicating at one end with casing 18 vbelow its valve seat and at its other end 4with casing 19 above its valve seat. The lower ends of the stems of valves 20 and 21 project through their respective valve Casin s and are provided with suitable packing g ands. The space; in casing 19 above seat. 23 communicates-directly with g respectively, 1 5
, the lower ends of stems of valves 2O and 21 therein. vWhen there is no pressure of steam cylinder 14 by means of a tubular connec- .tion 26, and the space below valveY seat 23 communicates with a waste pipe 27, the lower end whereof may discharge into a tank 28.
For the purpose of opening valves 20 and 21 by opposite movements of the beam 4, l
provide'a pair of - arms 29, 30, each being pivoted between ears or lugs 31 on casing 1 (see Fig. 3) to permit said arms to be moved in a vertical plane. Each arm is provided at its outer end with an elongated slot 32, 33, through which there extends a screw 34, 35 respectively, each of said screws being verticallyl adjustable in its slot, as by means of nuts 36 engaging opposite surfaces of the outer extremity of each arm. The lower ends :of the screws 34, 35 bear on-top of the beam 4, on opposite sides of the pivot thereof, and said arms are adapted to engage respectively.
With the. parts arranged as described, the operation will be as follows lz--Mercur or other li uid 39 which is not easily vol ati ized is intro uced in suitable quantity into the receptacle 8 and part of the mercury so introduced flows through pipe 9 into receptacle 7, compressing lmore or less the air in the boiler or the pressure is below the predetermined pressure at which the damper shall be closed, the parts are in the positions .shown in Figs. 1 and 4; that is to say, with vthe spherical receptacle 8 at a lower level than receptacle 7 and valve 20 closed. Under these conditions, the furnace damper is open. When the pressure of steam in the boiler increases, more or less of the mercury in receptacle 8 is forced into `receptacle 7,
compressing the. air therein. By adjusting the weight 13, the pressure at which the steam shall displace mercury in receptacle 8 Hto a su'liicient extent to cause receptacle 7 tooverbalance receptacle 8 may be varied.
When sufficient pressure has been developed to overbalance receptacle 8 and weight 13, valve 20 is opened by arm 29, and valve 30 closes by its own gravity through the movement of arm `3() away from the lower end thereof. The water or other fluid in pipe 2 4 then flows through-valve casing 18, pipe 25, valve casing 19 and connection 26 into the motor comprising cylinder 14- and the piston therein, depressing the piston and, through connection 16, closing the damper. When the pressure .of steam in the boiler falls to the predeterminedlower limit, the pressure of air in receptacle 7 transfers sufficient mercury therefrom into receptacle 8 to cause the beam to swing in the opposite direction, thereby allowing valve 2O to seat and valve 21t0 be opened through its arm 30. The opening of valve '21 enables the y open and close said damper,
pressure in said motor to be relieved, the weight of the damper lifting the piston in cylinder 14 and said piston expelling the fluid from the cylinder through connection 26, valve casing 19 and pipe 27. A forked bracket 37 having set screws 38 adapted to engage the upper and lower surfaces of beam 4 limits the movement of said beamin both direct-ions and insures the sealinglfat all times of the endsof pipe 9 by theme'rcury in receptacles 7 and8.
Should it be desirable 'to vary the pressure at which the damper will bei closed, this result may be easily accomplished `by moving the weight 13 along its support. Furthermore, by adjusting.V the screws 35 in their slots, the action of tl'e' beam 4 on the valves 2O and 21 may be varied.
From the above description, the drawings, it will be apparent that l have produced an apparatus of the character set forth which is simple of construction, which can be adjusted to meet the incidents of servicev and which can eciently utilize the pressure of iiuid for the purpose of operatingy the damper whenever the pressure conditions of the steam may require such operation. 1 i
While l have necessarily described the invention in detail, it will be understood that I ldo not desire nor intend that my invention shall be limited to details of construction, except as such details may be embodied in the claims hereto annexed or may be rendered necessary by the state of the prior art.
Having described my invention, claim is l y l 1. As a means for operating furnace dampers, the combination of a cylinder, a piston therein, means whereby the piston may be connected with the damper, and means for operating said piston to close the damper, said means comprising a iuid supply pipe connected to said cylinder, 'valves in said supply pipe, a beam pivoted intermediate of its ends and having at each end a closed receptacle, a pipe connecting the bottoms of said receptacles, said receptacles being provided with liquid partly' filling the same and said beam being arranged to operatively engage said. pivot as it 'tips to one side or the other, and a pressure supply pipe communicating with the central portion of said beam' and, through ene .arm thereof, with one receptacles, substantially as specified.
2. As a means for operating the damper of a steam boiler furnace, the combination what I whereby said per, and means for moving said piston toV said means comprising a supply -pipe communicating with one end of. said cylinder, a valve casingin taken withv l valves on opposite sides of itsof said,
