Application filed May 5, 1916. Serial No. 95,705.
.To all whom t may concern: i
Beit known that l, JAMES lzen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful lmprovements in Boiler v and other Furnaces, of which the following is a specification.
My invention relates to furnaces which are designed to-automatically serve the fuel and to similarly remove the ashes 4and other residual substances. Vented improvements in a furnace of this general type, as will appear by referring to my application, Serial #28,742, dated May 17, 1915, and to my Patent #1,171,803,
' dated February l5, 1916, in which are shown a hopper and an oscillatory fuel feeder, a'
stationary head blockconstituting the bottom of a' coking zone, a grate having reciprocatory stepped hollow bars, a rest grate, and means for removing'ashes from the furnace.
The present invention involves improved means for disposing of the ashes, and for sealing the discharge end of the furnace against the entrance of air other thanthat which is required for combustion and is admitted under proper control.
The invention also involves details of construction, as will hereinafter appear.
In' the drawings Figure l .represents a' vertical longitudinal section of the furnace; Fig. 2 is a vertical transversesection on the line mof Fig..1; Fig. .3 is an elevation of the water beam that in part supports the bridge wall, a portion being broken away to show the water pipes therein; Fig. 4 is va sectional view showing parts of the actuating mechanism for the ash remover; Figs. 5, k6 and 7 are sectional views showing the ejector for the ashes (called an ash drawer), andthe track plates on which it moves; Fig. 8 is a plan view showing in full' and dotted lines the rest grate, the ash drawer and the actuating parts for said ash drawer.
A is the hopper.; B, the oscillatory fuel feeder; C, the head block; D a grate bar; E the rest grate; F,l the refractory arch.
The top step d of the grate is somewhat higher than theother steps, and the parts are so related that when'the sections of the REAGAN, 'citil have heretofore in! Patenten nee., 2e, 1ere.-
scent of 'such particles of fuel as fall over the` edge of the head block. rlhe particles that have lodged on the upper face of the step (l when the grate bar was advanced are pushed off as the said Afaces are brought into coincidence.
v The ash drawer Gr is composed of sections G arranged in a transverse series and each section is an inverted hollow casting having slots g in its front and `rear walls, in which are disposed loosely mounted or floating Scrapers g having holes g2, through which small retaining bolts g3, extend. Grooved rollers gt, carried by brackets and running on the tracks g5 of a track plate g, sustain and carry the sections. rlhe sections are made unitary by bolts g, extending through adjacent sides.
The ash drawer is actuated by pull rods H driven by 'appropriate mechanism.- These pull rods are each pivoted at h to a pull piece hf having a square hole h2 receiving ay squarerod h3 that extends throughout the entire series of the sections G ofthe ash drawer G, the adjacentwalls of these sections being slotted from below at ktfor its reception. The square rod h3 is secured in place by pairs of lugs [1.5, each integral with a'wall of one of the sections G', to. each of i which pairs is bolted an' ear h6 of` a filler-l piece f1.7 for the slots h4. The ear h6 is of such dimension as to extend under the square rod h3 from one lug h5 to the other 3 connects the drive gear and the disk but I this bolt under excessive load will be sheared off and avoid the breaking of other and more important parts of the mechanism.
A pitman K is connected at its upper end to a pin 7c carried by the eccentric gear d, and is connected at its lowerend toa bellcrank lever L, which in turn is" connected to the pull rod Hby a pivot Z. The bellcrank lever is mounted on a bracket Zn. The pitman contains a telescopic joint the parts of which arerespectively a. sleeve s, and a rod 7a2, which in the absence of a pin 7c3, works idly. When the pin however, is `inserted the sleeve and the rod move in unison and motion is transmitted throughout the mits an oscillatory motion to the bell-crank .the rear end of the'grate.
entire train of mechanism, including pull rods H andthe ashdrawer G.` |The sleeve 7u lis slotted at 104 and 1a pin extending through rod 702 moves in these slots and pre? vents relative rotation of the parts. It also has the function of imparting motion to the sleeve 7c in one direction. An encircling tube los covers the-slots. i
The rotation o'f the drive shaft I trans- L,`and a consequent reciprocatory motion to Athe pull-rod'I-I and the ash drawer G. The
amplitude of this motion is such as to cause .the ash drawer G to alternately retreat into the space G3 in the lower part-'ofthe bridge wall Mandvto advance a distance sufficient to force the ashes toward the ash 4pit which it eventually reaches ,by passing through the space O under the back leg P of the grate. A protective sleeveA (.2, somewhat smaller than ithe space O, loosely surrounds "the end of the pull-rod H and moves with said rod.
This sleeve becomes full of ashes'which en' acter. The action of the ash-drawer is confined substantially to its face'L area so that the main body of ashes in the space above it being practically*undisturbed remains as a perfect seal. ,L
" The ash-drawer G is grooved at'the top and front for the retention therein of a'protective body of ashes. I employ what I designate water beams, R, R, one R, being placed at the base of the bridge wall and the other' R being used as a support for the rest grate. These water beams are made of castings containing wrought iron pipes which I have found to be especially effective in resisting the intense heat `of the furnace.
The water beam Itis especially useful in preserving the proper sectional area of the space G3 in which the ash-drawer moves, which, if affected, will cause the retardation or. stopping of the movements of said drawer. The bridge wall M contains a built in arch S, and is inpart supported by a back beam T. I f necessary-to repair the parts adjacent the ash drawer, the brick wall and the water and back beams below the arch S may be entirely and conveniently 'removed and reassembled without disturbing the main body of the bridge'wall.
, grate. dered certain.
I thus avoid rIhe above described devices, and espe- D cially the ash-drawer and its associated parts, are of great importance as means acting cooperatively with a furnace containing my improved fuel feeder and coking cha1n. ber, although they are of. much Value `in any furnace wherein air is likely to be im.
properly admitted at the lrear end of the The removal of ashes is alsoLrenvThe operation of my furnace is, as will be-understood, under perfect control. rll`he fuel is fed to -it in a steady and regulated volume, the distillation of the'fuel -is gradual vand certain, the supply-,of air isnot eX- cessive, the distribution of the air through the grate is uniform and combustion is unaffected by air admitted elsewhere, and the ashes are removed in such manner as to not interfere with the continualoperation of the furnace.- I have found by eXtensive eX- periments that the ash removing device arranged as disclosed herein. is effective 4in preventing combustion beyond the grate and confining it to its proper zone, and that difficulties-heretofore experiencedv in the burning out of the parts behind the grate have been entirely surmounted by theimpro-vements in the ash removing device herein described.
Having thus fully described my tion what I claim, is-
1. The combination with an inclined grate adapted to `discharge substantially the whole body of ashes from the rear end thereof, a bridge wall separated from saidl grate so invenvas to leave ,a space for the ashes delivered from said grate,A and an ashLremover consisting of a reciprocating ash-drawer adapted -to be retracted 'from and drawn through the ,lower portion of said body of 'ashes and a floor for sustaining the ashes over l which said ash-drawer reciprocates.'
2. The 'combination with an inclined grate adapted to discharge substantially the whole body of ashes from the rear end thereof, a
`bridge wall separated fro-m said grate so as to leave a space for the ashes delivered from. said grate, and an ash-remover consisting vof a reciprocating' ash-drawer having front and rear floating Scrapers, and adapted to be retracted from and drawn into the lower portion of a body of ashes.
3. An ash-drawer, the'body of which is adapted to move ashes and-'having front and rear floating Scrapers which have a free vertical movement independent of the drawer.
4. An ash-drawer composed of transversely disposed sections in combination with a bar extending through 'said sections and pull rods connected to said bar.
. An ash-drawer having a pull rod in4 e combination with a loose protective sleeve for said rod.
6. The combination of a grate adapted to names@ discharge substantially the whole body of ashes from the rear end thereof, a bridge wall spaced therefrom, and an ash remover disposed below said bridge wall and adapted, when moved from below said bridge wall, to expel ashes from the space between the grate and bridge wall and a floor for sustaining the ashes over which said ash-drawer v reeiprocates.
7. A furnace having in combination a grate, a bridge wall, and ash remover and water beams disposed on either side of the space between the grate and the bridge wall, the ash remover 'being contiguous to and protected by one of the said water beams.
In testimony whereof l afX my signature in presence of a witness.
