With respect to the drawings and the numerals of reference thereon, 10 designates the roof of a roundhouse which may have engine stalls in any desired number, 11 represents columns between the 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.

An up-take pipe or conduit 15 of the apparatus 14 may consist of an upper barrel 16, suitably supported upon the roundhouse roof, as by a closure hood 17 surrounding said 7 barrel 16 and an opening 18 in said roof through which the lower end portion of the barrel 16 projects, an intermediate barrel 19 having its upper end portion pivotally supported within the lower end portion of the barrel 16, as at 20, and a lower barrel 21 having its upper end portion telescopingly received in the lower end portion of the barrel 19, as at 22.

The pivotal arrangement between the upper barrel 16 and the intermediate barrel 19 is such that the barrels 19 and 21 can swing as a unit longitudinally of the track 13, and the barrel 19 includes elongated slots 23 in its opposite walls receiving the pivot pin 20 to allow for slight sidewise swinging movement of the intermediate and lower barrels, as, for example, to accommodate the uptake conduit to a locomotive smoke stack .which may not be exactly vertical, as will be understood. As shown more clearly in Fig. 2, the upper end 24 of the intermediate barrel 19 desirably snugly engages the inner wall of the belled portion of the upper barrel 16 to provide a slidable, preferably close fit between the barrels 16 and 19 no matter what may be their relative positions.

A counterweight 25, suspended from a cord 26 which rides over fixed pulleys 27 and is attached to the barrel 21, as-at 28, is for the purpose of counterbalancing the lower barrel, and the telescoping barrels are two for. each guide slat, having flanges 33,

which pass through openings in the barrel 19 and engage the opposite sides of said guide turesuitably supporting upper and lower,

horizontal' cross shafts, indicated 38 and 39, respectively, and 40 denotes a raising and lowering bar extending substantially longitudinally of the track 13, the rearward end portion of said bar 40 being freely received is between said suspension slabs and said horizontal cross shafts in such manner that the bar can have upward and downward swinging movement, as well as longitudinal sliding movement, but can have very little lateral or sidewise movement. The forward end portion of the bar 40 is rigidly attached, as at 41, to a yoke 42, which yoke in turn rigidly supports a funnel shape member 43 extending upwardly from the bar 40 and pivotally supported within the lower end portion of the barrel 21, as at 44. The pivotal arrangement between the lower barrel 21 and the funnel shape member 43 is such that said funnel shape member can swing longitudinally of? the track 13, and the funnel shape member includes elongated slots 45 in its opposite walls receiving the pivot pin 44 to allow for slight sidewise swinging movement ofsaid funnel shape member to better accommodate ,1

the up-take conduit to a locomotive smoke stack which may not be exactly vertical. The lower portion46 of the funnel shape member 43 is of configuration best suited to the re" ception of a locomotive smoke stack which,

is adapted to positively enter said portion 46, i i

and said portion 46 is cut away at one of its sides, as shown at 47, adjacent the. bar 40, to allow entry of a smoke stack into said portion 46. Also, the portions of the yoke 42 U and the member 43 at the general location of the cut-away portion 47 are obliquely disposed relatively to the body of the bar 40, slanting upwardly of said bar and inwardly of the up-take pipe or conduit, as represented at 48. As shown more clearly in Fig. 2, the upper end 49 of the funnel shape member 43 desirably snugly engagesthe inner wall of a belled portion of the lower barrel 21 to provide a slidable, preferably close fit be tween said member 43 and said barrel 21 no matter what may be their relative positions. Means for adjustably limiting downward movement of the lower barrel 21 in the interably secured to the yoke 42at location adja-' cent the funnel shape member 43, as at 51, passing upwardly through ears 52" upon a flange 53 set at the lower end of the barrel 19, and carrying nuts or collars 54 situated to engage the upper surfaces of said ears, each said nut or collar receiving a set screw 55 for locking the nut or collar at any preferred location along the length of the correspond- 0 ing rod. I

A counterweight 56, suspended from a cord 57 which rides over fixed pulleys 58 and is attached to the bar to as at 59, is for the purposes of counterbalancing said bar 40 and of normally situatingsaid bar and the funnel shape member 43 at about the'dotted line position disclosed in Fig. 1. p

A cover 60- for the upper end of the up-talre pipe or conduit is adapted to be closed at all times when the apparatus is out of use and is adapted to be open at all times when a locomotive smoke stack is situated in operative position relatively to the apparatus. As disclosed, the cover 60 is pivoted upon the 3, upper portion of the barrel 16 as at 6'1, and

includes a protruding arm 62 carrying a weight 63 of sutiicient magnitude to move said cover to open position. A cord or wire 64 attached to thecover at the side of its pivot opposite the weight is also attached to the end portion of the cord 26 which is adjacent to the barrel 21, the arrangement being such that when said barrel 21 is moved to its lowermost position by its'own weight and the g5 weight'of the bar i0, the cord 'or Wire 76% is drawn downwardly to move the cover to closed position against the action of the weight 63, but when the barrel 21 is elevated, said weight acts toopen the cover. Means may be provided for closing the cover even when a smoke stack is associated with the Lip-take pipe or conduit.

An exhauster for the up-take pipe or conduit 15 may consist of a usual or preferred type of fan 65 actuated by a suitablemotor 66, both shown situated upon the roundhouse roof. As disclosed, the upper barrel 16 has an opening 67 receiving oneendof a box 68 the opposite end of whichcommunicates meral 7 0 represents the fan housing outlet.

A valve 71 is for the purpose of closing up the passage through the up-take pipe or conduit and of opening an exhaust passage 72, leading from a locomotive fire box and through the exhauster, when the motor 66 is operated to actuate said exhauster, said valve 71 being adapted to open up the passage through said uptake pipe or conduit and to close said exhaust passagewhen said exhauster is not functioning. As disclosed, the valve 71 is pivoted in the barrel 16 at a location intermediate the ends of said valve, as indicated at 73, and includes an arm74 for 65 closing the passage through thejbarrel 16 with the interior of the fan housing 69. Nu-

and an. arm 7 5 for closing the passage through the box 68, one of said arms being in open a position while the other arm is in closed position. =lhe arm 75 is constructed to i be heavier than the arm'74, so that normally 36 the passage through the box 68 is closed and the passage through the barrel 16 is open. The arrangement is such, however, that when the fan 65 is operated, suction created in the box 68 is sufficient to draw the arm 75 to 1 about the position as disclosed in fulllines in Fig. 2, to thus open the passage through said box and close the passage through the barrel 16, as will be obvious.

The box 68 and the fan housing '69 are notpermanently connected together, but the arrangement is such that the exhauster or portable blower can be moved from place to place about the roundhouse, to be selectively associatable with the up-take pipe or conduit of any one of a plurality of different smoke disposal and draft inducing apparatuses, and means is provided for transporting the ex- 'hauster or portable blower about a round;-

house, along the top thereof as disclosed, to position adjacent any one of a plurality of diflerent smoke disposal and draft inducing apparatuses thereof and in smoke-tightrela tion to the box 68, or equivalent, of the corresponding apparatus.

s shown more clearly injFigs. 1, 2 and 8, the fan housing 69 includes a tubular inlet 7 6 the outer end of which, adjacent the boxes 68 of the different apparatuses, desirably integrally supports an outwardly extending annular flange 77, which'annular flange 77 is as shown perpendicular to said tubular inlet 7 6, The arrangement is such that when the fan housing 69 is positionedadjacent a box 68, about as shown in Fig. 2, the tubular inlet 76 and the exhaust passage 72 ofthe corresponding box 68 will aline. The tubular inlet 7 6 telescopically receives a tubular fitting 78, which fitting'is slidably, butdesirably snugly, arranged in the outer end portionof said tubular inlet 76, and extends outwardly of the exhausteror portable blower in direction towardthe several smoke disposal and draft inducing apparatuses of a roundhouse. When the parts are positioned 115 as in Figs. 1, 2 and 3, the tubular fitting 78 alines with the tubular inlet 7 6 and the exhaust passage 72, being disposed between said tubular inlet and exhaust passage.

The outer. end of the box 68 of each apparatus of the invention desirably integrally supports an outwardly extending annular flange 79, which annular flange 79, is as shown arranged approximately perpendicularly to the outer end portion of the corre sponding box'68, but has its marginal portion80 bent in curvilinear manner in direction toward'the' correspondingsup-take pipe or conduit. Also, the outer end of the tubular fitting 78 of the exhauster orportable blower desirably integrally supports an outwardly extending annular flange 81, which annular flange 81 is as shown arranged approximatelyperpendicularly to the outer end portion of said tubular fitting 7 8, but has its marginal portion 82 bent in curvilinear manner in direction toward the exhauster or portable blower. At location where the tubular fitting 78 meets the box 68, said fitting and box are shaped so that the outer ends of the fitting and box are somewhat nested, the one within the other as shown more clearly in Fig. 2. The annular flange 81 upon thetubular fitting 7 8 fixedly-carries small bolts 83 spaced apart about the circumference of said annular flange 81 and extending inwardly of the exhauster or blower and passing through openings spaced apart about the circumference of the annular flange 7 7 upon the tubular inlet 7 6. Coil springs 84, one upon each 7 bolt 83 and between the annular flanges 77 and 81, urge the tubular fitting 7 8 outwardly of the tubular inlet 76, and nuts 85, one adjustably arranged upon each bolt 83, normally engage the inner surface of the annular flange 77 to limit outward movement of said tubular fitting 78. See Fig. 2.

Of the means for transporting the exhauster or blower about a roundhouse, from stall to stall thereof, 86 represents a track which is shown in Figs. 1, 2 and 3 as parallel to a series of the apparatuses of the invention arranged in alinement with each other, in spaced relation to the boxes 68 of said apparatuses, the outer ends of all of said boxes also being arranged in alinement and parallel to said track 86. Spaced wheels 87 carrying the exhauster or portable blower are firmly mounted upon said track 86, and cords or cables, designated 88 and 89, respectively, arranged parallel to a vertical plane disposed longitudinally of the track 86, extend in opposite directions from said exhauster or portable blower and are attached thereto as at 90 and 91. The cord or cable: 88 passes over a pulley 92, disclosed as at one end of the roundhouse, to a motor 93, or the like. at this same end of said roundhouse, and the cord or cable 89 passes over a pulley 94, disclosed as at the opposite end of the roundhouse, to a motor 95, or the like, at said opposite end of the roundhouse, the motors 93 and 95 obviously being for the purpose of actuating the cords or cables 88 and 89 over the pulleys to aline the exhauster or portable blower with any desired one of the apparatuses of the invention, there being three of said apparatuses accounted for in Fig. 3 of the drawings, although a single exhauster or portable blower could serve for a greater or a less number of apparatuses. Any other suitable arrangement for transporting the exhauster or portable blower along the track 86 can be substi- V tuted for the arrangement as illustrated and described. 7

When the exhauster or portable blower approaohes the box 68 of an apparatus with which said exhauster or portable blower is at a particular time to be associated, the lip or reversely bent portion 82 of the annular flange 81 upon the tubular fitting 78 of said exhauster or blower guides said tubular fitting past the lip or reversely bent portion 80 of the annular flange 7 9 upon the box 68. As he exhauster or portable blower moves farther along, said annular flange 81 rides over the annular flange 79, this causing the coil springs 84 to be compressed somewhat, and eventually the outer end of the box 68 is seated into the outer end of the tubular fitting 7 8 when said tubular fitting reaches the appropriate position, as the parts are shown in Fig. 2, said box 68and tubular fitting 78 being positively assembled with each other at this time in smoke-tight fashion. Evidently, upon actuation of either motor 93 or 95, to move the exhauster or portable blower along the track 86, in either direction from the position as shown in the drawings, the coil springs 84 are compressed during the first part of the movement to allow the annular flange 81 to slide over the annular flange 7 9 until said flanges eventually clear each other. It should be remarked that the nuts 85 are positioned to limit outward movement by the coil springs 84 of the tubular fitting 7 8 and its annular flange 81 at location short of the position which would preclude clearance for the lip or reversely bent portion 82 whenthis passes the lips or reversely bent portions 80 of the annular flanges 7 9 upon the boxes 68 of the difl'erent apparatuses in a roundhouse. Supposing the bar 40 to be in normal position, say. for example. as disclosed in dotted lines in Fig. 1, and it is desired to associate a locomotive smoke stack with the lower portion 46 of the funnel shape member 43 of the up-take pipe or conduit 15, all that is neces sary to be done to accomplish this result is to move the locomotive from the dotted line position of the. smoke stack in said Fig. 1 toward the full line position of the locomotive disclosed. until said smoke stack has caused the bar 40. together with the member 43 and thelower barrel 21,to be elevated, and has entered the portion 46 of said funnel shape member. The arrangement is such that the smoke stack will snugly fit into the portion 46 of the member 43 when at any one of several different positions to provide a smoketight association between said stack and the up-take pipe'or conduit, as will be understood. After the smoke stack has associated itself with the'portion 46 of the member 43 of the up-take pipe or conduit, movement of said smoke stack still farther ahead will obviously cause the member 43 and the barrel 21 and the bar 40 to be still farther elevated and said bar 40 to be slid longitudinally ahead. Upon return movement of the locomotive, the smoke stack will not be removed from the up-take pipe or conduit until the rearward position at which the smoke stack entered the portion 46 has been passed, so that a locomotive can bemoved forwardly and backwardly within limits while associated with the up-take pipe or conduit of the apparatus without permitting smoke or gases to be emitted into a roundhouse. See the dotted line positions of the lower barrel 2'1 and the member 43 in both Figs. 1 and 2.-

The utilization of the improved raising and lowering mechanism actuated by the smoke stack of a locomotive to associate the up-take pipe with, and to disassociate said up-take pipe from, said smoke stack, eliminates all labor and maintenance which have heretofore been required to accomplish thev association and disassociation of stacks with apparatuses of the present character, and the arrangement as disclosed obviously makes provision for variations in the heights of locomotive smoke stacks, as well as for variations from the vertical as, may be caused by broken springs.

See both the joint at 20 and the joint at 44.

As will be evident, Whenever the bar 40 and the member 43 and the barrel 21 are elevated by a smokestack, the cover 53 will'be in open position, and when said bar and member and; barrel are allowed to lower, said cover will be closed.

.Obviously, when there is no exha-uster or blower at the box 68 of an apparatus, the arm 75 of the corresponding valve 71 will be positioned to close the exhaust passage 72, and the arm 7 4 of said valve 71 will be positioned to cause the upper barrel 16 to be open at the location ofthe valve. In fact, the only time the valve 71 of an apparatus is positioned as in full lines in Fig. 2, is when the exhaust-er or blower is in operative relation to said apparatus and the fan thereof is exhausting from the exhaust passage 72, as is thecase in said Fig. 2;
