Letters Patent No. 62,821, dated rifare/t 12, 1867.
GALORIG REGULATOR- FOR BOILER I'URNAGES.
TO ALL WHOM IT MAY QONGERN:
Be it known that we, J oHN GEORGE COOPER and EDWIN W. H. COOPER, of Hartford'in the county of Hartford.v and State of Connecticut, have invented a new and improved Calorie Regulator; and we do hereby declare that the following is a full, clear, and exact. description thereof,whicl1 will enable others skilled in the art to make and usevthe same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a sectional front elevation of this invention.
Figure 2 is a transversesection of the same.
Similar letters of reference indicate like parts. l
This invention relates to a regulator in which the air enclosed in a suitable heater and exposed to the action ofthe fire in the furnace, is caused to open and close adamper in the vfurnace door. A v
.Our apparatus `consists of a heater, B1, which is attached to the interior of the front plate A of the furnace, on the opening side of the door, as shown in the drawing, or if the apparatus is to be used for two furnaces, we place it between the two doors in such a. position that it will be heated by the burning fuel on the grate.A Said heater is fastened by a hollow stay-bolt,A4, which passes through the water space A3, and which acts as a thimble to receive theheater pipe C, one end of which is secured in the heater and the other `into a valvechamber, D. This chamber communicates through the passage Dl, with the regulating chamber or reservoir G, and consequently this reservoir communicates freely with the heater. The heater pipe C may, however, be secured directly into the regulating chamber G2, instead of in the `valve chamber D. The regulating chamber Gr2 is fitted with a piston, H1, which is secured to ascrew-rod, Il, and the screw-rod passes freely through the head G of the chamber GZ, and it is adjusted by the nut I2 so that the eifective space of the chamber Gr2 can be increased or decreased at pleasure.l The chamber G2 communicates through the passage G4 with the working cylinder Gr, which is provided with a piston, H, the rod l:V of which extends through the head G1, and this head is perforated to prevent back pressure. The pistons H and -H1 are hollowed' out on their -front sides, and lled .with plaster Paris, ire-clay,`or other-non-conducting material, to prevent the heat from producing an injurious effecten the packing. The piston-rod I is provided with a toothed `rack,-J, which gears-in a segment, K, mounted on a stud, R, and 'connected to a smaller segment, L, the teeth of which gear in teeth, O, cut into the rod P. This 'rod' passes through the spring box Y and a spring, Z, enclosedin this box, has a tendency to force the rod P in the direction og/th'e arrow markedv thereon in fig. 1, said s-pring being made to'bear on a pin passing transversely through the ro'd P.. Said rod passes4 clear through the 'spring box vY, and it isv provided with teeth, Q, which gear in a toothed segment, M, mounted on-a stud, R. From-this segment extends a slotted arm, N, which connects by a rod, T, and pivot, Si, with the damper-rodU. j This damper-rod is guided by a"slot, in the Vstud u, and by a bracket, S, which is provided with a guide groove to receive the head of the pivot S1. Suitable guid'e rollers, L h, prevent the rods I and P from getting out-of gear with their respective segments. The rod P is provided at its under side With a socketpa', to receive a dog, b, whichis hinged to one' end of'a lever, g, which has its fulcrum on a pivot, b1, and thel other end of which is subjected to the action-of a spring, c, which has a tendency to force the dog b into the socket a whenever said socket comes in 'the proper position, and' if thisv takes place, the d og f", which is also pivoted to .lever g, near to that` end which is subjected to thespring c, sinks down so that its lower end bears on the damper-rod U, On the upper side of the rod -Pis' secured an elevation or trip, d, which, when said rod-moves in the direction opposite the arrow marked on it in igl, strikes the rod Fl, which is guided iny suitable brackets, f1, and connects with the valve E enclosed in the chamberl D, and another trip, e,'serves for opening the valve which is enclosed in a chauibeigF, in the outer end of `the cylinder G. A hole, 11,2, in the inner end of this cylinder serves to introduce oil or other lubricating material. The'damper-rod U acts on an arm, X,vwhich extends from the slid-ing shield or damper V, which is insertedinto the furnace door A2. This door is secured 'by hinges, Z2, to'the frame A1, and it is provided with rectangular or other suitable, openings. It is locked by alatch, W ,pwith a slotted segmental guide, which' straddles a suitable pin, fw, and said latch locks with a catch, W1. Between the hinges Z2 a rod, l, is situated, which is guided in suitable brackets, and the` outer end of which acts on'a lifter or cam, l1, which is so shaped that when tne door is opened said rod is forced' in towards thelatchW. If thev damper V is closed and the door is opened, the
` head of the rod Z opens the damper, so thatno fresh fuel can be introduced Without havinfgt-he damper o1' cned.
In the'interio'r ofthe furnace door is situateda sheet, cl, with apertures of a circular, square, or any convenient form, and on the back or inside of this sheet is fitted the supplementary slide or regulator t', with apertures corresponding iu size and position to the apertures in the sheet cl. This secondary slide is adjusted by a button',
y', moving in a slot, lc, in thefront plate of the furnacedoor, and by this slide the quantity ofair to be admitted into the furnace is regulated, this quantity being variable according to Kdifferent classes of fuel requiring'differ- Aent quantities of oxygen to form a perfect combustion. Between the slide V and sheetfcl a chamber, b2, is formed, for the purpose of heating the air, andafter passing the slide z' the '-.air reaches a second heating chamber, all, situated between said slide and the blind-sheetel. Between this 'blind-sheet and the second perforated plate g1, (which forms the inside cover of the furnace door,) a third heating chambeigfl, is formed, and the air being heated while passing *through the several heating chambers, is admitted tothe fuel through the apertures in the plate g1. The damper or shield V, and regulatingsheet z', wil'lbev attached to the furnace door by means i of grooved projections at top andrbiottom of the door, so that they slide lfreely. The sheets c, el, and g1 may be attached to the door by mea-ns 'of thimbles inserted between them, and tie-bolts running through the hole in order to lock them together, or they maybe attached by means of shelvesv cast on the door or in any other suitableway. i i
The operation is as follows: When a fresh supplyof fuel is introduced in the furnace, the damperV is wide open, so as to admit the necessary quantity of atmospheric air, which, while passing through the several heating chambers, is heated, andin this state it passes through the perforated sheet gl over the burning fuel, thereby consuming the carbonio oxide and other gases evolved'ffrom the burning mass, and'preventing the same from escaping through the `smokejstack or chimney in the form of smoke. During this stage .of the operation the valves E andf remain closed, and the caloric in furnace acts on the heater Bl, causing the air therein and in the regulating chamber G2 and cylinder G to expand. As the fuel in the furnace becomes gradually more and more incandescent, the quantityof smoke evolved by the same diminishes, and'less and less air is required to consume such smoke, and in order to regulate the quantity of air admitted, the expanding airiu the heater -B1, chamber G2, and cylinder G acts on the working piston H, causing the piston-rod vI to impart-motion to the segmental gears K L, whereby the rod P is pushed back against the action the spring Z. At the same time motion is imparted to the segment M, and'throughl it to the rod U, which, by pressing on the sliding rodX, causes the-damper V to close gradually, so that the apertures in the furnace door are becoming smaller and smaller, until they are closed altogether. By these means a perfect combustion, or very nearly so, is eifected, the ordinary supply of air through the grate being now sufficient to the demands of the fire, until the furnace isagain charged with a fresh supply of fuel. As the rod P reaches the backwardl .end of its stroke it is caught by the dog b dropping into the=recess a, and at the same moment the trip d lifts the rod F1, thereby opening the valve E, and simultaneously therewith the trip e lifts the valvef, and4 cold air is admitted to the cylinder G, chamber G2, and heater B1. If the furnace is new opened, the latch W, by coming in' contact with a pin, ul, projecting from the under side of the rod U, causes said rod to rise and to press yon the pi-n g*, and thereby the dog J; is disengaged from the socket a, and the'irod P is permitted to follow the action of the spring. The valve E is closed, and the rodU and `pistoni-il: return to their original position, and as said piston reaches the back end of its stroke, the valve f closes, and the-apparatus is ready for-a subsequent action. In order to enable the trip e toretain the valve fiafter the valve -E has closed, said trip is made to slide back Vand forth in the trip d. As the door A2 swings open on its hinges, the rod l, by sliding upon the'cam Z1, causes the damper V to open automatically ready'for the next operation. By the regulating piston IP the -quantity of air in the chamber-Gr2 can be reduced, if found necessary, and by these means the pressure of the expanded air acting on the working piston is also reduced, and .the damper V is made to move slower and slower, 'according to the nature of the fuel used in thel furnace. The quantityof air admitted to the furnace can also be regulated bythe slide z', which is operated by means of the button. j, and which is set according to the nature of the fuel used. l I
