SMOKE-JACK FOR ROUNDI-IOUS'ES.

Application fi led October 8,1914. sealants-ecu. v

To all whom itmay concern:

Be it known that I, ORVILLE C. MANN, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented new and useful Improvements in Smoke-Jacks for Roundhouses, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The purpose of this invention is to provide an improved device in the nature of a smoke jack for round houses, having novel features for improving the draft for the locomotive served by the smoke jack and diminishing the draft by which the warm air might be drawn out of the round house, and for other minor purposes.

It consists in the elements and features of construction shown and described as indicated in the claims.

In the drawings: Figure 1 is a longitudinal vertical section of a smoke jack embodying this invention. Fig. 2 is a transverse vertical section of the same. Fig. 3 is an elevation of a fitting employed in the construction, the adjacent parts being shown in,

dotted line in their relative positions with respect to said fitting.

tion of the arrow, 4, on Fig. 3. Fig. 5 is a view similar to Fig. 1, showing a modification.

The smoke jack shown in the drawings has the usual form in general of smoke jacks for round houses, comprising the customary discharge stack member, 1, mounted above the round house, the customary stack mem-- ber, 2, mounted within the round house and discharging into the lower end of the member, 1, and the flaring intake mouth-piece or Specification of Letters .iiatent.

Fig. 4 is an elevation of the same fitting looklng 1n the direcing much more tapered upwardly in longi tudinal vertical plane to similarly meet the dimension at the lower end of the said meat ber, 2,'at the upper end of said hood. The side walls, 4, 4, of the hood, 3, extend lower than the end walls, 5. 5, of said hood, being outwardly flared at the lower end as to the excess of their length beyond the length of said end walls, forming flanges, 4 4 between which the locomotive stack passing under the ends of the end walls advances to position. Both the end walls and side walls are terminated at their lower edges by outwardly and upwardly-turned flanges forming drip troughs. 4 and 5 on said side walls and end walls, respectively. Fittings,

outer surfaces of the side walls. 4, 4, along,

the end edges of the flange portion, 4, and extending up beyond the angles between said flanges and the upper portion of said side walls to stiffen said angles and to afford 'means for attaching supporting hanger rods, 7, by which the stack is suspended from the round house roof, (represented as to its position by the line, 8). tings, 6, extending along the ends of the flanges, 4 and down into the drip troughs,

4 form end closures for the drip troughs, Each of said fittings is further provided With-a conduit, 9, rigid with the fitting, and extending through the flange'or web of said fitting which forms said end closure in an oblique direction so that the upper end of said conduit is presented under the adjacent end of the drip-trough, 5 of the adjacent end wall so that it may receive outside the web of the fitting in which it is -mounte'd, the' drip from said drip-trough,

while the lower end of the circuit overhangs" the drip-trough, 4", of the side wall. By this means the drip from the shorter end walls is delivered from the end wall drip-troughs down into the lower side-wall drip-troughs. For taking care of thedrip from tl'ieinn'er surface of the jack, flanges, 4 and 5", are riveted onto the inner surfaces of the side and end walls, respectively, the flanges, 4, on the side. walls being slopedtoward the middle of the width of said side walls for discharging the drip. through an aperture,

4 into the outer drip-trough, 4 ,of said side walls. troughs on the end 'walls, are extended through apertures, 4 inthe side. walls so that they also discharge into the outer driptroughs, 4 of said side walls. Said sidewall drip-troughs are clrainedby discharge pipes, 4 at the middle point oftheir length,

The chief purpose of this invention is toprovide 'means for restricting the draft through-the'j'ack stack as nearly as possible to the/locomotive smokestack sot-hat not only will that draft be as eflicient as possible, but also the jack will. be prevented; from drawing the warm air from the roundhou se outside the locomotive. For this purpose, in the construction shown in Figs. 1 and 2,

-there is provided'an up-and-down partition, 10, extending transversely of the hood,

3, being pivotally mounted at 12, mid-way in the-longitudinal dimension of the lower mouth of the hood, said partition extending from its said pivotedlower end upsubstan-- tially to the lower end of the straight up take member of the jack stack,-that is. to

the upper end of the tapering hood. This partition is wide enoughto extend from.

w side-wall to-side-wall of'thestack with only sufficient looseness of fit to make it free to,

rock overits fulcrumed lower end to swing its upper end from one side to the otherof the upper end of the hoodf-that is, from the l other position itwill similarly conduct the full-line position shown in Fig.1 to thedotted-line position in that figure. It will be seen that at one of these positions of the partition, 10, the hood will conduct the smoke from a'locomotive stack positioned under the right-hand half of the elongated lower mouthof the "hood into the straight up-take portion of the jack stack, excludingairjdrawn from the round-house from the left hand half of said mouth while at the smoke from a locomotive stack positioned under the left hand half of the mouth .to the exclusi'on of air drawn from the roundhouse through the right-handhalf.

The other rod, 14, is connected by admin, 18, extend.- ing over a.pulley, 19,- down to a position where it maybe operated toengage it witheitherone of three hooks, 20, for holding The flanges, 5 forming drip the partition at either of said leaning positions or at vertical position intermediate the two, as may sometimes be desirable. I

In the modification shown in Fig. 5, the partition there indicated by thernulneral, 21, instead of being fulcrumedat its lower end, is suspended freely on'two horizontal rods, 22, 22, extending from end-wall to end-wall of the hood at a level considerably above thecenter' of gravity of the partition, said rods having each two stops, 23, between whic'hthe' partition is lodged andsuspended upon the rods, s aid stops being at such position onthe rods, 22, that when the operating V rods,* 13 and 14, are operated to draw the upper endof the partition over to either leaning position shown in Fig. 1, the parti 1 tion stoppedagainst said stops is forced into inclined position, substantially the same as that which it'would occupy if fulcrumed at its lower end, as in Fig. 1. In this construction it will be seen that the partition will remain vertical throughout any range.
