To all whom t may concern.'

Be. it lrnown that I, EDWARD YoUNG,.a

citizen ofthe United States, residing at.

Pony Lake, in the county of 4Rock and State of Nebraska, have invented certain new and useful improvements in Stokers, of which the following is a specification., j

This invention relates to stolers for locomotives of the type illustratedr in an., application led by me October 25, 1913, Serial No..797,226, and in which -a rotary ejector operates within a casing'provided at its open Afront end with a door and gates or deflectors which are adjusted tovarious positions so as to control fthe deposit vof fuel in the lire box. Y

rlhe object of the present invention is to provide means whereby the door and deflectors will v to vary the point of deposit ofthe fuel upon the fire to the end that theentire sur-v face of the fire may be supplied withfuel continuously. j

y ln the accompanying drawings, which fnllvillustrate my` present improvements:v Figure l is a plan ,view of astoker showing one form of the present invention; Fig.

is a side elevation of the same; Fig. 3 is a. transverse vertical section on the line 3-3 of Fig. 1; Fig. 4 is a detail elevation of ai part of the gearing; Fig. 5 is a detail of anotherportion of the gearing; Fig. 6 is a plan view of a modification; Fig. 7 is a longitudinal section of the same'onv the line 7*'7 of Fig. 6; and Fig. 8 is a detail view Vof the reversing trigger.

T he` Stoker embodies a casing l having an arcuate rear end, indicatedV at 2, 'and pro-.V vided near said end with an opening .or hopi.

per 3 through which fuel may be'passed into the casing. Said casing is located in the cab of a locomotive with theJ open front end` thereof. arranged within thelopening of the fire box. The sides of the casing are straight' and parallel for the greater portion of their length, as shown at 4, andthe top andbottoni plates extend forwardly beyond'the sides and are provided with lateral eXtensions 5 between which are mounted verti-V the top wall-of thewcasingat the front end automatically operated so as.

trated, the fuel ejected from theycasing mayV pass to the backA of the fire box, and'when the door is lowered the furl will be deflected to points-nearer the front of the Vlire box.

fWhen the deflectors 6 'are inthe position shown in Fig. Vl', the fuel may pass from the.`

casing along vthe longitudinal line of the .Y

same, but as the delectors are shifted, the

fuel will be directed .toward either side of the :fire 'boin An ejector shaft 8 is mounted in the .top and bottom plates of the casing -and eX- of the same and is adapted to swing in tends below the casing where it is connect V ed to rotating and reversing mechanism,

Vindicated generally" at 9. This Aoperating mechanism 'may be Vof any desired consti-ucd w -tion and arrangement, and preferably coinprises steam cylinders 10 which contain pistons operating through suitable mechanism upon the shaft 8, and the said mechanisml embodies movable elements controlledby'a Vshifting lever l1 whereby the direction of rotation ofthe shaft S'maybe controlled.

The ejector comprises a series of blades 12 disposed radially to the shaft Sand fast to said shaft and adapted to sweep past theV f opening or hopper 3 so asto act directly upon' the fuel `passing through i said 0pening and force the same from `the casing. The ejector is provided with aV bottom plate 13 which iits'closely around the shaft` Sto vprevent the entrance of dust and dirt to the bearing of said shaft and thereby provent the. clogging of the same and consequent wear thereon. My inventionphas special reference to thel andV thedoor r7. The ejector is equipped with a pinion 41 upon its upper end, .which meshes with the straight face48'of a double lever beingi'fulcrumed. onthe casing ec-V mechanism for operating the deflectors ,(3 1

ico

. gear 46 which Ais carried by alever 52, said f centricallyl tothe gear whereby movement of the lever will carry the Vgear into Aor out of mesliwith the pinion 41. To facilitate this movement, the rear end of the lever is rprovided with any Aconvenient form of han-` die, as indicated atl `53. VThe'beveled face 47, of the double gear meshes kwith la beveled pinion 49to which is pivoted the rear elidV l of a .pitman'O having,` its frontend pivoted to an arm V5l risingfrom the door. The pinion e9 is one-half the sizek or one-half the diameter oi" the gear Wheel 46 so that it will make tivo complete revolutions While the Wheel V46 is making one revolution, and the door is thus raised and then again lowered While the deilectors 4are being moved once from side to side. The lever 52 has a lateral branch from W iich rises an iiptiirned armV 54: providinga bearingfor the hub or axle of the pinion 49, as Will be readily7 understood on reference-to Fig. 3.

In the illustrated arrangement, the pitman is not pivoted permanently to the pinion 49 but is constructed with a notch 55 adaptedy to engage. overa Wrist pin on the side face of the pinion. rlhepitinan may thus loe readil)T lifted out of engagement ivitli the pinion, if it should be advisable to -provide a series oit recesses or notches 56 in the lower edge of the pitinan which may be engaged over some convenient projection* in the locomotive cab.

The deflectors 6 are connected by a link 42 -to which is pivotalb7 connected the front end of a lever 43,5said lever being iilcriimed on the casing and connected at its rear end to a transverse rack bar 4% meshing with a pinion 45 which is fast to and Ac ncentric with the gear $6. Als the ejector shaft rotates,the pinion llovill impart motion to the gear Ll-G so that the pinions 45 and 49 Will be rotated. Through the pitnian Y50, the pinion Li9 will continuously raise and lower the door 7 and the pinion 45 acting' upon the rack 44 will. swing the lever 43 aboutV its fnlcriim so that the delectors Willy be turned to one side, as Will be readil)7 iinderstood'.V rThe several parts should .be so proportioned that'the door will be raised and lowered While the deflectors are moving l It With the. pinions 58 on the eiector shaft,

rlhe pinions are provided With oppositely disposed pawls 59 on their opposite faces arranged to engage ratchet Wheels 60 Which are slidahle on the ejector shaftbiit constrained to rotate therewith. readily vunderstood that the rack bars vare driven directly by the pistons in the. cylin-` derslO, the movement of which is reversed automatically 'by the action of valves in the steam chestsonthe sides of said cylinders.

lt Will beV lt will lalso be understood that, as therack bars ivorlr alternately, aV continuons rotationf` in one'direction will be imparted to the shaft.A To reverse thedirection of rotation, l provide means .vhereb57 the shifting; lever l ll will be automatically vibrated as the delectors roach the limitof their moveinent.` r'i'i'eversing bar 61 is slidahly mounted on the casing' and carries upstanding pins or 62 disposed at `opposite sides of the lever 43. A, connecting lever 63 is fulcriimed von the side of the casing withl its s iippei'end connected to the end of the reversing bar and its loiver end connected by an angle lever 6e with the shifting lever lil.' Thel inner-end ofthe shitting lever carries a. yokel 65 which engages the hubs-ot' the ratchet Wheels' G0: lVhen the reaches the limit oit its movement. .it'strilres1 one ot' the pins G2 and thereby slides the re versiii'g liar toward oneV side or" the casing, the motion being transmittedthrough the connected parts to shift thev ratchet Wheels so that the formerlyinactive ratchet Wheel. becomes a'ctiveand the active Wheel belevera3 i A comes inactive, the direction 'of rotationV ot and this pinion is adapted tofmesh with a. .Y

gear ivheel l5 which is carried` by a lever 16 fiilcriimed upon the casina at a pointin advance or the hiib or axis-of the E(rear Wheel.

and equipped at its rear endivith anv conu venient form 4of handle 17 whereby it mayY he swung uponeits'pivot soy as to nioieptlie f gearY Wheel into oi' oiit of -mesh vwith the e pinion ,14, as ivill 'befreadilv understood. The gear Wheel' 15 is adapted to mesh alter` nate-lv With rack bars 18and'l9'1Which areconnected`4 at their front ends by `a bai' 20'to Which is pivoted therear end of a link 21 having' its front end pi'voted to an arm 22 extending' 'upwardly from the door 7.' It

will be readiljv7 understood that, if the gear f Wheel he in engagement Withthe upper rack harlS, as shown in Fig.l 6, the door will be,l

moved in one direction, and if the rack bars' be shifted so as to bring the lower rack '19 'l into lenaanenie'nt 'iviththe gear Wlieeh `the door Will be shifted inthe opposite directioiiyalthfoiie'h tlie'direction of movement ot' thejgear Wheel is not changed. A second gear Wheel; 23 is arranged above the ,gearl *.vheelv yl5 concentric therewith, and this gear wheel. 23 engages a:Y transverselv disposed` rack bar24 to which is pivoted the rear end` o of a lever 25 which its frontend pivoted -r to a linl 26 forming,- a'conne'ction between 1,29

lever Q5 and the said oar and the rack bar- 19. A reversing bar Q8 extends between the front ends of the rack bars 18 and 19, and

this reversing bar is formed with a longitudinal slot which receives a triggery 29 fulcrumed at its lower end to a bracketv 30 secured upon the top of the casing and having its upper end projecting above the reversing bai' of the lever 25.

The shifting lever 11 is connected by a linlr 81 with an angle lever 32 suitably mounted upon the rear end of the casing, and one arm of this angle lever is pivoted to a lever 33 which is fulcrurned upon the top of the casing, as indicated at 34, and has its front end extendingover the gear wheels Y 15 and 23. @ne of the said gear wheels is provided with upstanding diametrically opposite pins, indicated at 35, which are adapted to alternately'impinge against the front free end of said lever 33 and thereby actuate the shifting lever 11 through the intermediate connections so as to reverse the driving mechanism, It is thought the operation of the appae ratus will be readilv understood. In the position shown in Fig. 6, the parts'are'in the midway position or just beyond the inidway position with the gear wheels 15 and 23 i rotating in the direction of the arrowand the door 7 is raised to a horizontal positionV lpracticallv extensions of the sides of the casing. The lever 25 has shifted thejref versine bar 2S through its engagement lwith thetrigger 29 so that the rack bar 19. has been movedout of engagement with the gear wheel 15 and the rack bar V18 has been brought into engagement with said gear. As the rotation of the gear wheels continues, the rack bar 18 will be moved toward the front of the casing and,v consequently, apush will be exerted upon the arm 22 'whichwill swing` the door downwardly. At lthe same time, the rack bar 24 will be moved toward the lower side of the ligure and the lever 25 will be actuated so as to swing the deflectors to the side. When the limit of the movement has been reachedoneofthe pins 35 will iinpinge against the free end of the lever 33 Vand will therebvvibrat'e said lever so as to actuate the angle'leve'r)J and link 31 thereby operating theshiftingV lever so as` to reverse the rotation of the' driving mechanism. The rotation of the eiector shaft S` will consequently be reversed, and

the detlectors will then be swung about their pivots to the oppositelimit of their movement, while the door 7 will be raisedand then again lowered. l/Vhen the direction of rotation is reversed through the engagement of lthe pin 35 and the lever 33, the gear wheels 15 and 23 will rotate in a direction opposite to that indicated by the arrow in Vwhat is claimed as new is A Fig. 1, 'and the rack bar 18'will then be moved rearwardly, while the rack bar 2li f Vwill be .moved towardthe top of the figure. When the parts reach the midway position,

the lever 25 will strike against the upstanding end of the trigger 29 and will swing the trigger about its pivot and thereby, through ,Y p the engagement Vof the trigger and the re'- versing bar 128, shift said reversing bar andV the rack bars connected therewith so that the rack bai' 18 will be shifted out of engagement with the gear wheel 15 and the rack bai' 1S brought into engagement with said gear. racir bars 18 and19 will, consequently, be reversed, although the gear wheels will not be reverseduntil a half revolution is The direction of movement of the I completed, lat which time the previously inactive pin 35 will engage the-free end ofthe lever 33 and oscillate the same so as tofreverse the driving` mechanism, as previously halfV revolution of the gear wheels, the dedescribed. It will thus be seen that, at each i iiectors will be moved fromLo-ne to the other extreme position so that the fuel will be drected first to one'side of the fire box :and

then to the other side of the same, while the i -r door i will be raised from its lowest position to its highest position and then return toits lowest position. A thorough distribution of the fuel over the surface' of the fire is thus automatically accomplished. N
