disclosed, guide slats 29 are secured uponthe outer surta-9e of the Vbarrel -21 in diametrically vepposed-relation-to each other, the said guide slats extending lengthwiseof said barrel 21K 60 preferably lyingin a plane which extends A.substantially longitudinally of. the.'v track 13, and-brackets V30, secured uponf the vbarrel 119 fas at;31, suppert guide rollers 32, twofor each gunde slet, during . langes 3,3, which 1 pass through openings in theabarreljleand;en-,

gage the opposite sides of said guide slats, the said guide Y rollers being mounted in said brackets as denoted at 34. A packing between the intermediate barrel 19 and the lower barrel 21 may be of any preferred design and construction.

` 5A raising and lowering mechanism of the apparatus, represented generally at 36, is adapted to be actuated by the smoke stack of fa locomotive to associate .the upltake pipe or conduit 15 with said smoke stack and to remove said-up-take--pipe or conduit from the Hsmoke stack. Of said raising and lowering mechamsm, STdeslgnates spaced apart`suspension slabs upon the round-house structure suitably supporting upper and lower, hori- `.Zontal crossshafts,indicatedBS and 39, respec- ,tively,and'denotes a raisingand lowering Vbar extendingsubstantially longitudinally of 4the;track 13, the rearward end portion of said bar 4() being freely received between said suspensionslabsandsaid horizontal cross shafts in` suehimanner that the bar can have upward' .and downward `swinging 1nove1nent,fas well as longitudinal Ysliding movement, but can have very litle lateral .or sidewise movement, and. the forwardv endportiony ofy said bar 40 being Ypivotally attached in any convenient manner, as at 41, tothe belled, cone-shape,'or

funneL-shapemouth 42 ofthe lower barrel '21, so that the, said bar ,40 is, normally suspended fromsaid lower barrel.

,Means., for adjustably limiting downward movement ofi the` lower barrel 2,1 in the in- .termedatebarrel ,19.ma-y consist of rods 43- suitably secured to the mouth of lsaid barrel 21asg-lat.44,passing upwardly through ears `4:5 uponaflange lsetat the lower end of the barrel ;19, and Vcarrying nuts or. collars ,L17

cars, eachsaid nutfor collar receiving a set screw 48 for locking ,the same at any preerred locationfalong the length of the corresponding rod.

A .colinterweight49, suspended from a cord` 50,whiehrides, over-lixed'pulleys 51 and is attached-to the bar'tO as at 52, is for the purposes ofcounterbalancing saidbarLO, and of 4normally situating said bar andthe up-take pipel at aboutthe dotted line position dis- .i Closed innig. 1. l

'n A cover153 forv theupper end of the up-take pipegor. conduit is adapted, .to be closed at yall k.times whentheapparatus is out of use and is `adapted tofbe openjat all Atimes vwhen a locoymotive ,smoke stack is -situated in operative position relativelyv to the apparatus. As disclosed,thelc'overV 53 is pivoted upon. the upper portion of thebarrell as at 54, .and in- 56 of suicient magnitudel to move said cover i to openlposition. A cord or wire 57 attached ,toz the .cover :at the side of its pivot opposite 'the weight isalso attached to the endjporton .f of. thermal-126 which isfadjacent the .barrel situatedl to engage the upper surfaces ,of said cludes a protruding arm carrying a weight 21'the arrangement being such that when the said barrel 21 is moved to its lowermost position by its own weight and theweight of the bar 40, the cord or wire 57`is drawndownwardly to move the cover to 'closed position against the action of the weight 56, but when the barrel 21 is elevated, said'weight acts to open the cover. Means may be provided for closing the cover even when `a smoke stack is associated with the up-take conduit.

An exhauster for the Lip-take pip-e may consist of a usual or preferred type of fan 58 actuated by a suitable motor 59, both shown situated upon the round-house roof. As disclosed, the upper barrel 16 has an opening 60 receiving one end of a box 61 the opposite end of which communicates with the interior of the fan housing 62. Numeral 63 represents the fan housing outlet.

A valve 64 is for the purpose of closing up the passage through the up-take pipe or conduit and of opening an exhaust passage 65,

Vleading from a locomotive re box and .Y as indicated at 66, and includes an arm 67y through the exhauster, when the motor 59 is operated to actuate. said exhauster, the said valve 64 being adapted to open up the passage through said up-take pipe or conduit and to close said exhaust passage when said exhauster is not functioning. As disclosed, the valve 64 is pivoted in the barrel 16 at a location intermediate the ends of said valve,

for closing the passage through the barrel 16 and an arm 68 for closing passage through the box 61, one of said arms being in open position while the other arm is in closed position. The arm 68 is constructed to be heavier `than the arm 67, so that normally the passage through the box 61 is closed and passage through the barrel 16 is open. arrangement is such, however, that when 'the fan 58 is operated, suction created in the box 61-is suiiicient to draw the arm 68 to labout the position as disclosed in Fig. 2, to

n dotted line position ofthe 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 lower;

barrel 21, to be elevated, and has entered the mouth of said lower barrel. The arrangement is such that the smoke stack will snugly fit into the mouth of the lower barrel when at any one of several different positions to provide a smoke-tight association. between said stack and the up-take pipe or conduit,

The

as 'will be understood. After the4 smoke stack has associated itself with the mouth of the up-take pipe or conduit, movement of said V.smokev stack still farther ahead will obviously cause the `barrel21and the bar 40 to bestill farther elevated `and said bar40 to beslid longitudinally ahead. Upon'return movement of the locomotive, the smoke with, and to disassociate said up-take pipeV from, said smoke stack, eliminates all labor and maintenance which have heretofore been required to accomplish the 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.

As will beevident, whenever the bar 40 and the Ibarrel 21 are elevated by a smoke stack, the cover 53 will be in open position, and when said bar and barrel are allowed to lower, said cover will-be closed.
