VENTILATING snC'rIoNAL SMOKE JACK.

original No. 1,551,979, dared April 2o, 192e,I serial reissue led February 12,

This invention relates to` smoke `jacks adapted for use in round houses, engine houses and the like to assist the escape of smoke from the stacks. olf locomotives and the escape of steamwhen a boiler is blown oft.

One of the objects of the invention is to form a box-like structure whichv is very strong, stable and durable thereby reducing installation and maintenance costs to a minimum. Also, the sectional design simplifies themanufacture, enables the usefof standard material, and involves less risk,`

l breakage, and damage in handling.'

A further object is toprovide a sectional .Ventilating smoke jack which not only conducts the smoke or steamvfrom the stack of a locomotive ydirectly to the outside of the house or other enclosure, but also assists in Ventilating the space beneath `therool' due to the fact that two sides of the interior portion of the jack form Ventilating openings located substantially at roof or ceiling level. y'

W'itli` the above and other objects in view which will more readily appear as the nature of the invention is betterunderstood, the saine consists in the novel construction, coi'nbination and arrangement of vparts here-v inafter more fully described, illustrated and claimed. y .Y

A preferred and practical ernbodiment ofA the invention is shown in the accompanying drawings, in which 1 y V' `Figure 1 is a vertical sectional view of the improved construction.

Similar reference characters ldesignate corresponding parts throughout the severalf igures'of the drawings. y

i The present inventionrelates particularly to a Ventilatingv sectional 'smoke stack construction coniprising .sections adaptedto be made up in the shops-nd then shipped to the point of installation, and has in Viewl certain improvements on my former PatL ents Nos. 1,150,878, dated August 24, 1915 and 1,314.016 dated August 26, 1919.` lIn the respect that the present inventionl contemplates a sectional ventilating smoke `jack the present invention represents acarrying forward of the idea shown in my Patent No. 1,314,016 aforesaid. A

By reference to the accompanying *draw-` ings it'will be observed that one of the distinctive vfeatures ofthe present construction resides in providing adequate Ventilating openings located substantially at roof or ceiling level thereby to more adequately pro`` vide for the removal or carrying` off of they gases collected beneath the roofdue tothe e]ector action set up by the forcedor in` duced draft incident to the rush of smoke or steam passing through the interior hood resides in forminglthe malin side sections in such a way that they take a direct bearing on the roof of the structure on which the j smoke jack is installed.

As will be observed from Figsilft to 8 inclusive the .present construction includes in `its organization the vmain side-sections A,

the endsections B, the exterior Hue-sections C. the extension sections D forthe main side-sections, and the top or cover piece E. The main side sections Apreterably consist of a .body 1 having the upwardlyinclined side edges 2 which converge toward'thefv cap portion 3 of said section and intersectthe bottom edge of the ycap portion 3st apoint inside of the outer corners 4 thereof, thereby to provide the root 'engaging shoulders 5.u The side edges of the cap portion 3 are also inclined upwardly but at lesspitch than the side edges 2, thus providingwthe main secftion A with' two pairs of inclined, vand c0netl A further feature y vergently related .side edges, one pair arranged Vbelow the roof and the other `above the same. Y

`The end sections B are stantially rectangular formation and. the

-side edges 6 thereof are adapted` to be fasshown in Figfl.4 The end-sections B are.

duplicate-and interchangeable for either end of the lmain side sections, and areV therefore of standard size and design.A

The cap portions 3 oflthe main side-sections 1 which project above the roof R` cooperate with the'side-sections C andthe extension-sectionfD to. provide an exhaust ue which communicatesv with the hood H formed by the sides A and the endsl B, and also 'with thel relatively large Ventilating openings 9 located substantially at roof or ceiling level and communicating with the spaceunderzthejroof R.

i TheY Hue forming sections theretothe smoke,` steam or other gase's'may readily exhaust yet at the same time the cover piece E will prevent rain or the' like falling into thebuilding through the smoke jack. l

the' main side sections, andthe extension sections D, itwill be observed that the sides thereof areinclined upwardly thereby to provide". an exhaust Hue which tapers toward the discharge end throughout one of its'dimensions,` thus having the'fetfect of Vstimulating ejector action to carry` ofi' gases or the like accumulated beneath the roof.V

In installing the device, whichy as previously indicated, may be shipped in knocked-v down form, dueto itssecti'onal construction,

it isproposed to cut a hole 11 in the roof R, the sides 12 of the hole being provided with.' the corner abutments 13' for cooperating with the shoulders 5 rof thev main side sections A.y After the hole 11 is cut in ac` cordance Vwith the conguration shown in Figa-.3 the Vside sections v1 maybe lifted y through` the opening and then shifted laterally until the shoulders 5 rest upon the corner abutments 13, thereby supporting the main sections directlyion the roof. To assistrin securingthe kside sections A the same maybe `bolted as indicated at 14 (Fig. 1) to 5f.

the cross beam 15 rcarried by the rafters 16, Thus, in addition to supporting the -side sectionsdirectly on the loutside or top of the roof the asteningsk 14 may be utilized. to insure permanency and stability. In installingthe devicehowever, the shoulders 5 preferably of sub-A C and D arepreferably-provided with the openings 1()- so that-whenthecover. piece 'E is appliedv fing openings.

tributing the'aveight of the hood to the rafters 16 where that is desirable.

` The sections C vand D which cooperate with the cap portion 3 of the main side sections A are preferably secured together at their meeting edgesk by nails, screws or equivalent fastenings, and to provide a practical and durable connection between the flue and the voutside ot the roof a collar 17 may be built about the lower end of the As shown in'Fig. 9 thecollar17 and the.

side of the jack maybe cut to connect with the' roof vent Rwlien encountered. however is a merevexpedient of installation incident to certain types vof roof construc-v tion and does not alter thelfunction or struc tural features of the invention.-

A feature ofpractical importance in the present invention Vis:the structural one, regardless. ofthe material of which the smoke jack is made, of the topflue'or stack C-D arranged .over andabove the roof opening and the hood, H arranged below the hood .Inpconnection with the cap portion 3 of and'having its two opposite walls B-B eX- This tendingl into the roof opening and spacedl from the adjacent edges of said roof opening thereby to form two opposite ventilat- This form [of construction provides two Ventilating openings in the most advantageous locations in order to discharge therethrough any' accumulations ot smokeor gas which otherwise might become trapped immediately under the root, while at the same time permitting the other sidel walls AD of the jack tobe united or joined and lsubstantially continuous from top to bottom of the jack. Furthermore, it will be `observed that thesupporting. cross beams 15 and the fastenings 14, though; an optional feature of the invention.; provide a stable supporting means carried with 4the roof structure which assists in strongly sus-- pending the' hood proper. from the roof structure so that thev particular feature above described may be embodied inthe jack construction in a thoroughly practicable manner.` I

From the foregoingjit will be apparent thatthe present sectional type ofV construc-` tion` carries forth. the "idea of my former Patent No. 1,314,016 supra in rath'oronghly practical and effective manner. The various sections of the jack may be readilymade in shops or other convenient places and readlasA ily transported to remote points of installation where only the lservices of a carpenter or other workman are required to erect and assemble.

Without further description it is thought that the features and advantages ofthe present invention will be' readily apparent to those. skilled in the art, and it will of course 'be understood that changes in the foi-improportion and minor details of construction may be resorted to, Without depart-ing from the spiritof the invention and scope of the appended claims'. In that connection it may be pointed out that the present construction embodies features that make it possible to use other materials than Wood, such for example as asbestos, sheets of concrete, metal and the like. Thus,l While the drawings' illustrate a wood jack of mill type construction, itwi'll be understood that the embodiment shown merely is an example' of one Way of carrying the invention into effect, the construction being such that any other material may be selected. j i
