SPECIFICATION forming part of Letters Patent No. 302,365: dated July 22| 1884.

' Application tiled April 6, 1883. Renewed January 2S. 1 8r4. (.\'o model.)

To all whom, it may concern.-

Be it known that I, ARTHUR WARNE, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Furnace-Fire Feeders; and I do 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 ywhich it appertains to make and use the same,` reference being had to the accompanying drawings, and to letters or iigures of reference marked thereon, which form a part of this specification.

My invention relates to that class of furnace-fire feeders through which any light finely-divided fuel-such. for enjaznpleas the refuse of planing mills-is automatically conducted through a ronduit lo the tirenit of a furnace from any point near to or far from such furnace hjzineans et' n powerful blast of air from nsuction fan; :ind it consists. substantially.ol'certain novel nrnuigenients and coinbinations oi' parts h v nieans'ol' n'hichJii-st, the blast of air from the sucl ion l'nn, however powerful, is under eomplcteand automatic control; second, the danger from fire by backpressure is entirely avoided; third, the apparatus can be quickly and easily moved out of the way when access to the furnace-doors is desired; fourth, the mouth of the feeder can be readily and accurately adjusted to and from the furnace-doors; fifth, the fuel can be distributed readily to any and all parts of the furnace.

I will now proceed to more fully describe the manner in which I have accomplished these objects just named.

In the drawings, Figure l is aside elevation of my improved apparatus. Fig. 2 is a vertical sectional View cfa portion of Fig. 1. Fig. 3 is a detail View of the dciiecting-valve and its operating mechanism. Fig. 4 is a front 'view of one ofthe furnace-doors. Fig. 5 is a scctional view of a fastening device for the hinged sections. Figs.' 6 and 7 are views ofthe fueldistributer. Fig. 8 is a view of the valve for regulating the supply of fuel. Figs. 9, 10, 11, and 12 are enlarged detached perspective views ofthe dierent valves for regulating and controlling the blast of air. Fig.- 13 is an enlarged perspective view of one of the hinged joints in the conduit; and Fig. 14A is au enlarged front view of the fastening device for the hinged sections.

Referring to the drawings, the main conduit for the passage of the fuel is composed, substantially,of two sections-the upper section, a, and the intermediate section, a. The section a is divide 'atthe poi uta-into two branches, each leading to separate doors ofthe furnace. One of these sections is shown at ain Fig. l, and the other at c in Fig. 2. is hinged to section a at the point b, so that it may be swung back out of the way when desired, and is securely held in operative position by the fastenii'rgr device clearly shown in Fig. 5, in which thc 'flanged and shouldered ends ofthe two sections are provided with the lugs b' b2. The lngl b upon the section u, has pivoted to it the hail b, having the tighteningscrew bt, which bail is swung under the lug bi of the section a', and there held securely by means of the tightening-screw b. (See Fig. 13.) Rach of the lower branches, a. und c, is similarly hinged and secured, so that they can be either independently swung back out of the way or swung with the section u', lo which they are hinged.

c c are similar fastening devices, two in number, upon each branch c or a", whichenables its lower portion to be entirely, removed when desired.

The section a.'

'd is the suction-fan,which is located at any convenient pointvand which supplies the feeder with fuel by means ot' its suction and blast.

The suction a of the conduit is provided at or near the point where itconunences to curve downwardly with the customary valve, E, for regulating the quantity ot' shavings or fuel to be fed. This valve is a hinged section of the side of the conduit, and is moved int-osuch conduit any required distance to cut off a portion of the passing fuel by the following apparatus, which forms a part of my invention.

A casing, E', (see Figs. l. and '8.) is secured to the side wall of the conduit opposite the hinged valve E, in which are vertically arranged two pulleys, lli EL. Just below the hinged valve E, and secured to the conduit, is the projecting arm E, provided at its outer e V s023265' end with two pulleys, E* E. A cord o`r chain,

f, is secured at a point on the outer'face of t e valve E, and passes down over one of the pu u l leys L and 1s secured to one of 'two arms, f

j", of a crank-lever, f2. Another cord or chain, f, is secured at a point on the inner face of the valve E, and passes around the'pulleys E2 El and under the conduit to and over one of the pulleys E* and down to the other arm, f', of the lever f. By turning the lever f2 and securing it in any one of the holes f4V in the curved bar f'l the valve E can be held securely in any desired position and a portion of the fuel thrown outinto `the fuel-room when it is found necessary to do so.

` AIn the section a ofthe conduit I have ar' ranged two swinging valves, 71l and 7c, pivoted to the top' wall of the conduit.A These valves vare 'swung forward more or less by the blast of air from the suction-fan, and when suc-h blast is turned off they return to their normal vertical position by the force of gravity, the valves being made somewhat heavy for that purpose. These valves are connected with certa-in other valves and cut-offs `in the section c', and by their movements, as just described, serve to automatically regulate the valves and cut-offs connected therewith. To be more explicit, the valve h has the lever h. rigidly secured thereto and adapted to move therewith.

To the outer end-of this lever h is loosely -se cured the connecting-rod h2, which is in turn loosely secured to a short lever-arm, h, rigidly attached to a journal, 71.*, pivoted in the bracket hi of the conduit-section c. Upon the journal h4 is rigidly mounted the toothed segment h, which engages with and operates the toothed .bar hi, which forms :a rigid extension of the sliding valve hs. (See Fig.- 10.)

'i is another connecting-rod, loosely secured to and forming a continuation of the rod h2. To the end of this rod is connected the arm fiof a crank-lever pivoted in the bracket 2, the other arm, i, of which crank-1ever is' loosely connected to the short rod fi, attached to the the conduit-section through a slot, k6, in the front wall thereof.V (See Fig. 12.) Another p'ivoted valve, Z, adapted to swing downwardly, is .located near the lower end of conduitsection a. This valve, like the valves h and lc, is operated by the blast of air from the suction-fan, and is automatically closed when the blast is shut ofiby the weight Z upon the lever-arm l?, which is rigidly secured to thevalve l and moves with it. To regulate the extentv to'whieh the valve l may bey opened by the blast, a lever-arm, la, similar to lever-arm Z2,

. is rigidly attached to such valve, and a cord,

Z, is secured to its outer end, which cord passes over a pulley, Z5, and down to the 'plate Z", l

where it may -be secured in any one ofthe holes ZT with which the plate ZG is provided.

l is a frame against which the valve l rests when in closed position, to form a comparatively tight joint. {See Fig. 9.)

At the-point where the section a of the conduit is divided into the branches a3 and a* is located the valvem, for closing up either one of the branches and feeding from the other only. This valve 'm has a lever, m', rigidly attached thereto, which is loosely bent around the curved guiding-rail m2, its end which extends beyond such guiding-rail being used to, turn the valvefrom one side tothe other.

Each branch a a* has a cord, n, secured to-it, which cord passes over a pulley, n', and carries a counter-weight, ai, at. the other end,

which enables either of the hinged .branches a3 or a* to be easily and quickly `moved' back from-the furnace, and held infsueh position when access to the furnace is desired; or the section a, with .its branchesfa3 a,'can together be similarly mani ulated.

`In order to hol the discharge-openings of the branches in the desired position with relation to the furnace-doors, and tokeep them.

carefully adjusted in such position, I have se- 'cured them removably to the furnace-front,

above the furnace-doors,by the wires or chains o o, which have the turn-buckle o attached midway, so that by manipulating such turnbuckle the desired adjustment can be easily l andreliably effected. I 'prefer to keep the discharge openings of the feeder a short dis- ,j tance away from the furnace-doors, as clearly shown in Fig. l, preferably within from one to two inches therefrom,to enable the fireman to instantly detect the state of the re with respect to the amount of fuel introduced into the furnace.

The furnace-doors I preferably construct as clearly shown in Fig. 4, in which p is the casing to which is hinged the open frame p. This frame is provided with grooves or ways, in

which the removable plate p2, forming the main portion of the door, slides. By this construe.. tion I have a doorwhichl is not only adapted to receive the fuel from the feeder, but can bev quickly adapted for use as an ordinary furnacedoor when itis found necessary to dispense for a time with the feeder.

I have constructed the discharge-openings of the feeder in such a manner that the disposition of the fuel can be easily regulated. This improved construction .,is, clearly shown in Figs. 6 and 7, in which 'si-ls the pivoted bottom, hinged at s', ashort distance back of the discharge-opening. This bottom is provided with the side pieces, s2, which lap over upon the sides of the main portion of the dischargeopening,

loops s, which encircle the buttons or thumbscrewss?, secured upon the sides of the discharge-opening. `S5 are spreaders arranged radially upon the movable bottom s, as clearly shown in Fig. 7. By moving the hinged bottom s up or down, the distance towhich the fuel can be thrown is correspondingly regulated, while at the same time the radial spreaders operate to thoroughly distribute the fuel horizontally within the furnace.

t is a passage opening'into the conduit-section a on its under side and at or near its junction with section a', through which passage the surplus air can escape. This passage t is preferably extended back to the room from which the shavings are first started to the furnace, being intended to provide for the return to the shavings-room of any fuel which might pass. with the surplus air. into and through such passage t. l

It will be seen from the foregoing detailed description that the danger from fire by backpressure when the blast is shut off is entirely.

avoided, as the valves h and k close by their own weight when the blast ceases, and by means of their connection with the valves h2 and k5 automatically close these valves as well, and in the same manner open the valve i5, so that if any sparks should happen to pass back as far as the valve they would be thrown out into the furnace-room. The automatic valve Z also serves as a similar additional precau I claim- I 1.
