Serial 1T0. 581,689; p

This invention relates to a smoke-disposal and draft-inducing apparatus, for locomotives of the type utilized in roundhouses' for n conducting the products of combustion from 5 the stacks of, and for inducing draft inthe. furnaces of, locomotives. r

The broad object of the invention is to provide an apparatus of the character mentioned i which will be useful-in any relation but will be more especially useful when'incorporated into an ordinary or preferred form of jack ras. customarily employed in roundhouses, and in which will be incorporated various novel and improved features and characterloistics of construction designed to render the present apparatus an improvement generally over moreor less similar apparatuses here'- tofore known.

Further objects'are to equip the'u'p-take pipe or cond'uitof the apparatus with a cover actuated by improved means to be closed at all times when the apparatus is out of use and to be open at all times when a locomotive smoke stack is'situated in operative position relatively to the apparatus; to equip the apparatus with a novel and improved valve adapted to close up thepa-Ssage through the 'up-take pipe or conduit and open an exhaust 36 when the exhauster or blower of the apparatus is causedto function, and to open up the passage through said up-take pipe or conduit and close said exhaust passage when said exhauster or blower is not functioning; to equip the apparatus with an exhauster of novel and improved construction; to provide in the apparatus an up-take pipe or conduit of novel and improved construction; to provide in the apparatus an up-take'pipe or conduit and an exhaust'er each of which can be associated with an ordinary orpreferred type of roundhouse jack in novel and improved manner; to equip the apparatus with a raising and lowering mechanism adapted to be automatically actuated to associate the up-take pipe or conduit of the apparatus with, and to remove said up-take pipe or conduit from, the smoke stack of alocomotive in novel and improved manner; to so construct said raising and lowering mechanism passage leading from a locomotive fire box and. saidup-take-pipe or, coiiduityand to so associate said mechanism and said up take pipe or conduit witheach other; that said mechanism can' be actuatedby the smoke stack of a locomotive to assemble" said up- 5 take pipe or conduitwith, and to remove said up-take pipe or conduit from, Said smoke stack; to provide in the apparatus "a novel; and improved arrangement permitting-a 10- v comotive smoke stackto be in 'communica-tion (in with'the up-take pipe or conduitof saidapparatus at variable location in thevicinity". of theapparatus, thus making it possible to 1 move a locomotive backwardly or'forwardly V withinzlimitswhile beingvfired, or while a fire exists in the fire 'boxfwithout emitting.- smoke or gases into a roundhouse; to provide 7 in the apparatus a novel and improvedanrangement adapted'to care for variations in the heights'of locomotive smoke stacks; and to associate the telescoping members 7 and barrels,;respectively, of the up-take pipe or conduit of the apparatus with each other so that therefcan beeno binding of said telescoping members'and barrels. I V I I Other objects and advantages of the in vention will become apparent fromthe full description thereof now'to be made, it being understood that the disclosure herein is 'merely illustrative and intended in no way in a limiting sense, changes in details of con struction and arrangemen't'of parts being permissible as long as within the spirit of the invention and the scope of the claims which follow. A I v s5 In theaccompanying rawing's forming a part of this specification, f I r Fig. 1 is an elevational view of an apparatus in which the'features' ofthe invention are iincorporated;disclosing said apparatus applied touse; 1 I L 'Fig. 2'is "a detailsectional View taken as on 1ine2'2in'Fig. 4; V, m I h Fig. 3 is an enlarged vertical sectional view of the up-take pipe or conduit and the 'ex-' 555 hauster of the apparatustaken substantially as on;line 33 injFig. 4; with partsbroken away and additionally, sectioned for the sake ofbetter disclosure; and i Fig i'is a vertical'sectional view'of'the apparatus taken substantially as on line 4.4 in Fig. 3.

With respect to the drawings and the numerals of reference thereon, 10 denotes the roof of a roundhouse which may have en gine stalls in anydesired number, 11 represents a jack above one of the engine stalls, and 12 indicates a locomotive upon a track 13 and within a stall.

A separate smoke disposal and draft inducing apparatus, denoted generally at 14,

may be provided for each stall with jack of a roundhouse', or an apparatus made according to the invention in many of its particulars may be provided'for a greater or less number of stalls which are without jacks such as 11.

Each jack 11 may be of ordinary or preferred construction. The jack disclosed is shown as consisting of spaced apart, vertical sidewalls 15 and spaced apart, downwardly diverging end, or forward and rearward,walls 16, said side walls and end walls together pro viding ahollow, vertical structure having a horizontally disposed, "open, upper 'end 17 which is approximately square in configuration, and a horizontally disposed, larger,

'open,'lower end 18 which is of rectangular shape and arranged directly above the track 13 with the longer sides of the rectangle extending parallel to saidtrack;

The roundhouse roof 10 isprovided with an-opening 19 for each jack 11, and the jacks are arranged in said openings to approximately fill the same, a majorportion of the jack extending above the roundhouse roof,

and a minor portion thereof projecting downwardly into the roundhouse. As disclosed,

L-shaped brackets 20 attached to the round-' house roof and to each jack, retain the aclrs in stationary position. g

Each side wall 15 of the jack fixedly sup ports a plate 21 parallel with the adjacent jack wall and slightly spaced therefrom by means of bosses 22 which are desirably integral with the outer surfaces of the plates 21. Themeans for attaching said plates 21 to said side walls 15 of the jack consist of bolts or screws 23 which pass through the side walls 15 and enter the bosses 22.

The plates 21 provide spacediapart side walls for the improved smoke-disposal and draft-inducing apparatus, and each plate 21 may be of about the configuration and. size, relatively to the size of the jack 11, as. best disclosed in Fig. a. That is to say, each plate 21 includes an upper rectangular portion of width slightly less than the'widthof a side wall 15 adjacent the upper portion thereof, and a lower portion which diverges in down ward direction fromjthe lower end of said rectangular portion, the lower end of. said divergent portion being of width aftrifle less than the Width of a side wall 15 adjacent the lower portion thereof. The upper end'of each plate 21 may desirably terminate a. trifle above the upper end of the jack 11, while the lower end of each said plate 21 may terminate at considerable distance above the lower end of said jack, as said plates are shown in Figs. 3 and 4. The upper and lower edges, respectively, of the plates or side walls 21 desirably cured to and between the plates or side walls 21 of the apparatus in any convenient manner to provide a rectilinear box constituting the upper portion of said up-take pipe or conduit and including all of the walls 241, 24 and I parts of the walls 21, 21.-

The up-talre' pipe or conduit of the apparatus also includesan upper intermediate portion or passage constituted by lower portions of the plates or side walls 21 and by downwardly extending, swingable members 25.

which are hingedly supported upon the lower ends of the end walls 24,as at 26,sai-d members 7 25 each being of width to extend practically the full distance between said plates or side walls 21', as shown more clearly in Figs; 3 and l,so that the passage provided by said plates or side walls 21 and saidmembers 25 will be, in effect, swingable transversely of the structure' constituting the up-take pipe or conduit of the apparatus. Each of the members 25, consists of telescoping plates 27 adapted to have; movement toward and from eachv other whereby to accomplish longitudinal adjustment of each said member 25. As shown, one of the plates 27 of each member 25 supports spaced apart headed and nutted bolts 28, including a headed andnutted bolt arranged in each of parallel slots 29 in the other plate 27 of said member 25, and a small cover plate 30 is arranged over each slot 29 torender said members 25 smoke-tight.

The members 25 slant toward one side of the jack 11 andconverge in a downwardly direction, in the manner as best disclosed in Fig.4. Abarrel 31, constituting a lower intermediate portion of the up-take pipe or conduit of the apparatus, has the forward and rearward side edges of its upper portion hingedly supported, as at 32, uponthe lower edges of the lower plates 27 of both members 25. The upper portion of the barrel 31 is oblong in cross-section, including longer walls 33 adjacent the hinges 32 and extending between the plates or side walls 21 at the location of the upper parts of said walls 33,- and shorter walls 34: havingtheir upper provide said upper portion of the barrel 31 extenddownwardly beyond the plates or side plane of "the track 13, directly above said track. Also, said runways 36 extend in the direction of the length ofnsaid track 13, and

have their opposite ends rigidly supported upon the end, or forward and rearward, walls 16 of the jack, as denoted at 37 in Fig.- 3. 'The cylindrical part 35 of said'barrel 31 integrally supports bosses, denoted 38, including four bosses 38 extending outwardly, of said cylindrical part from each side there-, of, all of the bosses at a side of the cylindrical part being parallel with each other and perpendicular to the runway 36 at the corresponding sideof the barrel. The four bosses 38 ateach side of the cylindrical part 35 of the barrel 31 are arranged in two sets of bosses with twobosses to the set, one set ofbosses 38 being a trifle above the corresponding runway 36, and the other set of bosses being a trifle below said corresponding runway. All of the bosses 38 of the two upper sets of bosses, at both sides of the cylindrical part 35, are in the same horizontal plane, as are also all of'the bosses 38 of the two lower sets, at both sidesof said cylindrical part. A roller 39' is mounted ineach boss 38- and each roller 39 is flanged, as at 40, tofit'uponan edge of arunway .36, it being apparent that the cylindrical part 35 of the barrel 31 is thus fixed to the runways 36 to be slidable' therealong, there being four upper rollers 39 rigidly supported by and spaced about the cylindrical part 35 with opposite rollers rest ing upon the upper edges of the difierent runways, and four lower rollers 39 also rigidly supported by and spaced about said cylindrical party with opposite rollers in contiguous relation with, or closely adjacent to-, the lower edges of the difierent runways, and there also being a lower roller 39 directly op posite and beneath each-upper roller 39.

A lower barrel 41'of the up-take'pipe or conduit of the apparatus has its upper end portion telescopingly received in the lower or cylindrical part 35 of the barrel .31, and the flanged upper end 42 of the barrel .41 lies in theoblong portion of said barrelj31 to limit the extent of downward movement ofsaid barrel 41, as will be more clear from Fig. 3.

The pivotal arrangement at the hinges 26 and 32 is such that the barrel 31.can have movement lengthwise of the runways 36 in eitherdirection, the members 25 lengthening or shortening, ,as the case may be, depending upon the directionin which said barrel 31 is slid along saidrunways. That is to say, when the barrel 31 is slid along the runways 36 from its position as in Fig. 4-toward the left, the members 25 will shorten as said barrel .31

moves, naturally, closerto the hinges26, and

whensaid, barrel 31 is slidalongjthe runways in opposite. direction, said members 25 will-lengthen as: the barrel moves farther '7 from said: hinges 26, the shortening and lengthening operations of said members 25 being permitted by the slot and bolt connections of the plates 27, as hereinbefore set forth; As will be apparent, the members 25 i are mounted to be swingable longitudinally of the track 13, and the barrel 31 is mounted to 1 be reciprocable longitudinally of .said track. As will hereinafterbecome apparent;

the barrel 41 is adapted to have qvertical movement in'the barrel 31,,said barrel31' desirably being vertically disposed." Said barrel 41 extends toposition somewhat be-= neath, the jack. I p

I A raising and lowering mechanismsof the apparatus, represented generally at 43, is

adapted to ,be actuated bythe smoke stack of a locomotive to associate thelower barrel.

41 with said smoke stackand to remove said lower barrel from said smoke stack. Of'said raising and loweringmechanism, 44 designates spaced apart suspension slabs (only. one

being shown) upon the roundhouse" structure 4 suitably'supporting upperand lower," horizontal cross shafts, indicated 45 and .46, respectively, and 47 denotes a raising and lowering ba'r'extending substantially: longitudinally of 'the track-13, the rearward end portion ofsaid bar ,47 being freely received between said suspensionslabs and said horizontal cross shafts in such manner that the bar can have upward and downward swingmg movement, as well as longitudmal sliding movement,but can have very little lateral or sidewise movement. The forward end portion ofthe bar47 is pivotally attached,

as'a't 48, to a barrel carrier 49, which carrier:

is in turn. rigidly attached, in anysuitable manner as by welding or otherwise, to the lower barrel 41. The pivotal arrangement between the bar :47 and the barrel carrier ,49

is such that said bar and carrier can have vertical swinging movement relatively. to v each other. The lower portion of the barrel 41 is of configuration best suited to thereception of alocomotive smoke stack which is adapted to positively enter the'fiared mouth 50 of said lower barrel, and said mouth 50 is cut away at one of its sides, as shown at 51,

adjacent the bar 47, to allow'entry of a smoke stack'into said mouth 50. Also, the cut away portion 51 of the mouth 50' is desirably cord 53 which rides over fixed pulleys 54 and Y is attached to the bar 471as at55, is, for the purposes of counter-balancing said bar 47 and of normally situating said bar and the barrels 31 and 41 at the dotted line position I disclosed in Fig. 1, which corresponds to the of the apparatus as in 21, as at 57, andincludes a protruding arm 58 carrying aweight 59 of suflicient magnitude to move said cover to open position. A cord or wire 60 attached to the cover 56 at the side of its pivotopposite the weight 59 is also attached, at its opposite end, as at 61, to a shaped element 62 itself welded or otherwise connected tothe flared mouth of the lower barrel 41. Asdisc-losedmore clearly'in Figs. 3 and 4, the cord or wire 60 passes down wardly between the plateor side wall 21 having the pivot-57 and the adjacent side wall 15 of the jack, and rides over anidler pulley. 63 which is suitably mounted upon this same mentioned plate or side wall QL'desirably at about-the location as shown. The arrange ment is such that when the barrel is moved to its lowermost positionby its own weight and the weight ofthe bar 47, the cord or wire 60 is drawn downwardly to move the cover 56 to closed position against the action of the weight 59, but when said barrel 41 is ele vated, said weight 59 acts to open the cover. Means may be provided for closing the cover even when a smoke stack is associated with the uptake pipe orconduit. "An exhauster for the up-talre pipe or conduit of the apparatus may consist of a usual;

or preferred type of fan 64 actuated by a suitable motor 65, both shown situated upon the roundhouse roof. As disclosed, one side wall 15 'of the ack and the adj ace nt plate or side wall 21 of the apparatus have alined openings 66 arranged at about the midwidth of said side wall 15 and the midlength of said jack, which openings 66 receive one end of a fan inlet 67 the opposite end of which con-- municates with theinterior ofia housing '68 for the fan 64. Numeral 69 represents an outlet for the fan housing 68 which is received in. alined'openings 70in the same side wall 15 and plate or side wall 21 which iave the alined openings 66, said openings 70 aiiording communication between the fan outlet 69 and the stationary portion of the up-take pipe or conduit defined bythe walls 21,. 21, 24, 24, as shown very clearly in Figs. 3 and 4. The outer end of the fan outlet 69 terminates just within the plate or side wall 21 adjacent the openings 70, and is said plate orside wall-'21. 1

.A valve 71 is for .the purpose of closing up: the passage through. the Lip-takev pipe or conduit and of opening an exhaust passage parallel to 7 leading from a' locomotive. fire box. and

through the exhauster, by way of the fan inlet'67, the fan housing 68, and the fan outlet 69, when the motor 65 is operated to actuate said exhauster, saidvalve 71 being adapted to open up the passage through said up-take pipe or conduit and to close said exhaust passage when said exhauster .isnot functioning; As disclosed, the valve 71 is fixed upon a small shaft 72 which has its opposite end portions rotatably mounted in the end, or forward and rearward, walls 24 at location above the alined openings 66 andbelow the alined openings 70, as at 73, said shaft 72 being arranged closely adjacent to and parallel with the plate or side wall 21'hav-ing said openings66 and 70, and being disposed horizontally. The valve 71 extends practically the full distance between the walls 24, and upwardly from the shaft 72. The normal position of said valve 71 is'as shown infull lines in Fig. 3, where the'valve is disclosed held inapproximately vertical position,

against the outer end of the fan outlet 69 to close it, by means of a weight 74. Said weight 74 is adjustable longitudinally along oneend portion of a lever 75 which has its intermediateportion pivoted,-as at. 7 6, upon a boss carried by the outersurface ofone of.

- end of. the lever- 75 which'receives a pin 79 carried by a short lever fixed upon an' extension'of theshaft 7 2. The weight 75 is of magnitude to normally depress the adjacent end of the lever 75 to" elevate the portion 77 thereof having the-elongated slot 78 to cause the lever, 80 to be pushed upwardly and the valve 71 to effectually close the fan outlet 69 in the'manneras disclosed inFig. 3. The arrangement issuch, however, that when the fan 64 is operated, to create vacuum at the fan inlet 67- and pressure at the fan outlet 69, as will be understood, the pressure will force the valve 71 away from said fan outlet, to about the dotted line position as shown in Fig. 3,- to thus open the exhaust passage which is constituted by the fan inlet 67, the fan housing 68, the fa'noutlet .69 andthe portion of-the up-take pipe or conduit defined by the valve 71, when in the dotted line position of said Fig. 3, and the portions of the walls 21, 21, '24, 24 which are at this time above said valve. When positioned as in dotted lines in Fig. 3,'sa'id valve 71 effectually closes the conduit. Obviously, when the fan 64 .is brought to rest, the weight 74 immediately acts in the manner as hereinbefore set forth to move said valve 71 to its full line position as in Fig. 3, .thus closing said exhaust'passage and opening the up-take pipe or conduit.

' Supposing the bar 47 to be in normal position, say, for example, as disclosed in dotted linesin Fig. 1, and'it is desired to associate a locomotive smoke stack with the mouth 50 of the lowerbarrel 41 of the up-take pipe or conduit, all that is necessary to be done to accomplish this result is to move the :locomoa tive from the dotted line position of the smoke stack in said Fig. 1 toward the full line positionof the locomotive disclosed, untilvsaid A smoke stack has caused the bar 47, together with the lower barrel 41,-tobe elevated, and

has-entered said mouth .50 ofsaid lower barrel. The arrangement is such that the smoke stack will snugly fit into the mouth 50 when at any one of several different positions, as the barrel 31 slides longitudinally ofthe runways 36, to provideia-smoke-tight association between said stack and theup-take pipe or conduit, as will be understood. After the smoke stack has associated itself withthe mouth of the lower barrel 4:1, movement of said smoke stack still farther ahead will obviously cause said lower barrel and the bar 47 to be still farther elevated and said bar 17 to be slid longitudinally ahead. Upon return f movement of the locomotive, the smoke stack will not be removedfrom the up-take pipe or conduit until the rearward position at which the smoke stack entered the-mouth 50 has been.

passed, so that a locomotive canbemoved forwardly and backwardly within limits while associatedwith the up-take pipeor conduit of the apparatuswithout permitting smoke or gases to be emitted into around,- house.

r The utilization of the improved raising and lowering mechanism actuated by; the smoke stack of a locomotive to associate-the up-take pipe or conduit with, and to disasso ciate said 'up-take pipe or conduit from, said smoke stack, eliminatesall labor and maintenance which have heretofore been required,

to accomplish the association and disassocia- .tion of stacks with apparatuses'of the present 7 character, and the arrangement as disclosed obviously makes provision for variations the heights of locomotive smoke stacks.

As will be evident, whenever 'thefbar 47 and the lower barrel 41 are elevated bya smoke stack, the cover '56 will be in open position, and when said bar andibarrel are allowed to lower, said cover will be closed; Particular attention is called :to the fact that the onlytime the valve'7'1 of the appara tus is positioned as in dotted lines in Fig. 3, is when the fan 64 is exhausting, At all other times,.said valve 71 is positioned as shown in full lines in said Fig. 3.
