EDWIN FITTS, OF DETROIT,A MICHIGAN, ASSIGNOR TO DETROIT STOKER COMPANY, OF DETROIT, 'MICHIGANQ A CORPORATION' 0F MICHIGAN.
.AUTOMATIC-STOKR FURN'CE.
To all 'whom it may concern:
Be it known that I, EDWIN Frr'rs, a citizen of the UnitedStates of America, residing at Detroit, in the county ofWayne and State of Michigan, have invented certain new and useful Improvements in Automatic- Stoker Furnaces, of r,which the following is a specification, reference being had therein to the accompanying drawings.
The invention relates to furnaces ofthe type provided withautomatic mechanism vfor stoking andthe invention comprises various features of construction as hereinafter set forth.
In the drawings:
Figure l is a perspective view of the furnace- 2 is a front elevation thereof;
Fig. y3 is a sectional elevation of the motor for actuating the stoking mechanism;
Figs. 4, 5 andv 6 are respectively a plan view, longitudinal section and'front elevation of the gate-operating mechanisml for the Stoker.
Fig. 7 is a detail view of the fly-wheel.
A is the furnace front, B is the fuel'door for hand feeding, C are doors to the magazineD is the mechanism for operating the various movable parts of the stoker, such as the fuel feed, clinker-bars, etc., and E is the motor for actuating said mechanism.
It is usual with furnaces of this type to provide a steam-actuated motor having a step-down gearing for rtransmitting movement to the Stoker mechanism. Frequently the gearing or some portion thereof is exposed and the dropping of coal or other material into the gears interferes with their operation. I have therefore devised a construction of motor unit which includes not only the engine ybut also the step-down transmission gearing, all of the parts being housed so as to protect the mechanism from dust and dirt. posed in such a manner that the only portion lprojecting* bevond the furnace front is the crank arm or actuating the 'Stoker mechanism.
In detail, F is the engine having the pitmen G connected to a crank shaft H having, a fly-wheel I .at its forward end. J is a gov- The mechanism is also dis Specification of Letters Patent. Patemjad @atl 95, 191'?, Application led October 15, 1915. Serial No. 55,950.v I'
worm on the crank shaft y engaging the worm-gear M of an intermediate shaft M .having the worm N engaging a worm-gear N on a shaft O arranged below and parallel to the crank shaft. All of these parts are mounted upon a base or frame P, and the shaft O projects beyond this frame and has secured thereto the crank Q. The stepdown gearing, as well as the governor, ilywheel and other parts of the mechanism, are all housed.
Where the motor is not 'self-starting it is f deflection of said lever. Thus the operator by pressing the lever inward toward the iiywheel can engage it with one of the ratchets to rotate the wheel 0E from the dead center.
It is usual to arrange above .the magazine ahopper for a largerlquantity of fuel from which the magazine is supplied. Whenever it is desired to stop the feed this hopper must be cut of and `I have therefore provided a novel construction of gate-operating mechanism therefor as follows: 'I`
i-s a slide or gate for closing an opening T inthe bottom of the hopper. U is a connecting -rod pivotally attached to said slide and extending longitudinally of thel magazine, being connected at its outer end to a bell-crank lever U. This lever is pivotally connected to a-bearingV, which is attached to the frame C for the 'doors C. The :actuating arm .U2 of the bell-crank normally extends laterallv above the door opening and is socketed to receive a lever. rIhe doors C are fashioned to close over the inwardly-projecting arm of the bell-crank, one of the doors being cut-away for the outwardly-projecting portion of said arm. rIhe arrangement is such that whenever it is d'esired to cut 0E the supply to the magazine, by inserting the lever in the socketed bell-crank arm U2 and drawing outward thereon, the sliding gate T will be shifted to close the openlng T.
As has been stated, the furnace is provided with a door B through which the fuel may be fed by hand. For operating this door I have provided an automaticallylatching handle W, as shown in Fig. 1. This handle isv pivotally connected at W to the door, and has an outwardly-extending bent portion W2 forming the handle grip and an inwardly-extending portion "W8 which is hookedvto engage a keeper W4 on the door frame. The portions W3 and W4 are beveled so that in the closing of the door they will automatically pass each other,per mil-,ting the latching of the hook into engagement with the keeper. When, however, the door is to be opened the lifting of the handle W2 will disengage the hook and permit the door to be swung upon its hinges.v
What l claim as my invention is 1. In an automatic stoking furnace', the combination with a f urnace front, a magazine in rear thereof and a door controlling an opening through said front into said magazine, of a gate controlling the feed tol ing through said door opening into saidv nagaat@ Aa plane below the u per edge of said open ing, a gate controlling the feed to said magazine, a pitman rod connecting said arm to said gate, and a door for closing said opening adapted to lit over said actuated arm.
3. In an automatic stoker furnace, the
combination with a magazine and a door opening in the furnace communicating with said magazine, of a gate controlling the feed to said magazine, and lever mechanism for operating said gate mounted outside of said magazine and extending through said door.
thereinto and arranged to clear said door in the closed position thereof.
In testimony whereof l aiix my signature in presence of two witnesses.
