4, The; hot vapors froml the yarns. cominginto contact with the cool-,top wall ofthezslashenhood .and with the walls ofthe exhaust; ducts. are condensed in apart: To. prevent; the condensate .thus formed from fallingonxthezyarns andldam-aging mthem, -I have provided a seriesof baflles: [.8 which extend across the f.ull .width. of. the 1 space, over the sheet of yarns andare disposed with a slant .4 of the-same order .as: that ofthe .hood but. of

smaller. degree; That is; the baffles arewmounted .so-.that.the terminahedgejof each which isnearer the upper; end of-the hood isgrat a. higherelevation than theterminal edge. which is nearer: to

4 thelower end ofthe hood. AJso the bafliesare arranged'in overlapping relation so thatthe lower edge oigeach higher bafileoverlaps: thBnU-PDGI ledge, ofrthe next. lower baffie; but with a. space of substantial height -:between their overlapping portions. Thusthevapors rising from theiheated yarns, together with air drawn into4 the hood, can

:pass .freely. between the overlapping. bafliesl but zanywatendripping from'the topof the hood-0r from theexhaust ducts is caught .by thebaflies. PM maybe noted hererthat the baffiesare-preferably mademf rectangulartplatesof stifi -sheet nletal, such asgalvanized iron,- but with-their upper side edge-and end. edges bent up to form lips or rim walls I9 and 20,-and the loweredge of each (except that of the lowermost bafile) bent down as shown'at zl; in Fig 3: These rim walls confine the-water falling OIlithGbfifflES and guide itto lower bafiies, until it reaches ultimately the lowermost baflle 22.

The bafiie- 22 differs from the-othersin' that its lowerend is upturned to forma-lip 23-an d thence is turned down-ward andbacl; for -a-purpose-later described; and that the lips 2000 at theends of the bafiietterminate short of the;1ip- 23, to provide escape passages or 911171817824: The water falling 4 on baflle'22, therefore, is obstructed and-deflected and caused to 'fallinto gutters 25 on the sidewalls of the hood beneath the-outlets 26. {*The gutters maybeconnected with drains or arranged in any 3 other manner suitable to dispose of the Water received therein.

The bafiies herein described are eiiective also for disposing of water which condenses on their under surfaces. The condensed water adheres by capillary force and flows to the downturned lip 2! at the lower edge of the bafile before gathering in sufiicient quantity to drip. Thus the only dripping of water condensed on the under surfaces of the several baffles is from the lower edge lip of each upper baiiie to the next lower bafilein the series. For receiving and conducting away the condensate on the under side of the lowermost baffle 22, the part of thatbaifie whichis turned up to form the lip 23, previously described;

is further carried downward and then bent backward and upward until its extreme edge -26 is located beyond the corner or zone 21 at which the lip 23 is bent up. This construction provides a channel 23 open at one side, due to a space left between the edge 26 and bend 21, to receive water condensing on the under side of the baflle,and open at both ends over the gutters 25, .whereby it can discharge the water so received into those gutters. 1

The hood and means for supporting the baffles therein contain .novel features of construction as follows:: The upright side walls l,l, -which are preferably of uniform width except at the lower end, and the top wall are preferably made of sheet metal such as galvanized iron and are secured together by locked joints, substantially as shown in Fig. 2. The longitudinal margins of the top wall are bent up at right angles forming ribs 29, and the upper margins of the side walls are extended along the outer sides of the ribs 29 and the bafiies rest on shelves 4| formed of iron angle sections welded, or otherwise suitably secured, to the inner faces of the walls I I, such shelves having a length slightly shorter than the width of the baflles and being positioned with the inc1ina tion prescribed for the baflles. Hooks 42, one of which is shown in Fig. 3, are secured to the baffies in'positionito overhang the upper ends of the respective shelves when the baffles are placed on the latter, These hooks may be made of short pieces of sheet metal welded or otherwise secured a to the under sides of the respective bafiles adjacent to their upper corners, and bent down. When a baflieis in place, the shelf on which v either end rests is embraced between the hook 1 42 at that end and the adjacent end of the downturned lip 2|. most 'bafile 22, the curled under part which forms the channel 28 hangs below the lower end of the folded overand pinched against the inner sides of these ribs. At their'lower ends the side walls are rolled inward and upward to form the gutters 25, being first cut to an outline which enables such gutters to be located approximately horizontal but with, preferably, a slight downward inclination toward their outer ends. Removable extension'wall sections 34! and 3l are provided'at each side of the hood. The section 30 is made of a plate of sheet metal similar to that of which the walls It and II are made, and to it-near its opposite side edges are secured

hangers

32 and 33 made of strips of angle iron, the upper ends of which are curled over to form hooks 34 adapted to be hung on the beads constituted by the joints between the top and permanent side walls. The

hangers

32 and 33 are of unequal length such .that, when so assembled with thehoocl, their lower ends will be at'the same level, and the plate 30 is so cut that, when in assembled relation with the hood, its bottom edge will be horizontal and its upper edge 35 will overlap the lower edge of the adjacent permanent side Wall H and. be at an inclination similar to that of the top Wall.

The extension Wall 3! is made of a triangular plate of like metal to which hangers 36, 3'! and 38, of the same nature as the hangers 32 and'33, are secured, whereby the extension 3| may be detachably suspended in the same manner. The upper edge of the plate forming this wall is disposed to overlap the adjacent, side wall I l and has a similar, inclination. Permanent side sections 39 and 40 and an end wall embrace and enclose the outer portion f the drum b.

The removability of the

side wall extensions

30 and 3! on each side of the hood permits ready access to the space between the permanent walls H in which the baffles are located. The ends of shelves.

It hardly needs saying that the shelves which support any one bafil'e are at corresponding levels so that the bafile supported thereon is in an inclined plane of which the elements lying in the width dimension of the hood are substantially horizontal.

The hood may be supported by structural members resting on the floor which supports the slasher or suspended from the ceiling or roof; such supportingor suspension means being omitted from this description since they constitute no part of the present invention and may have various forms.

The descriptive terms used in the foregoing specification are not intended to limit the invention or its field of use to less than the scope embraced by the appended claims, such claims being intended to include all embodiments in which the novel principles of the combination here described may be applied.

What I claim and desire to secure by Letters Patent is:

, .1. A slasher hood comprising an inclined top nent walls in sloping series generally parallel to .the top wall, corresponding supports on the respective walls being at substantially the same height relatively to the top walls, and baflle plates removably mounted on said supports to extend across the spaces between corresponding supports, each bafiie being inclined with a slant of the same order as that of the top wall, but less in degree and the lower edge of each upper baffle overlapping the upper edge of the next lower baflle in the series with an intervening space.

2. A slasher hood as set forth in claim 1, in which the several bafile plates have hooks which overlap their respective supports so as to prevent the bafiies from sliding off from the supports.

3. A slasher hood as set forth in claim 1, in which the battle plates have upwardly extending lips at their ends adjacent to, but separate from,

' the side walls of the hood to prevent water fall- But with respect to the lowerside walls adapted to overlie and embrace the upper parts of a slasher and having an outlet for air and vapor, baflle plates extending across the space between the side walls in an inclined series, being substantially horizontal in the direction from side to side of the hood and inclined in the direction transverse thereto with a slant of the same order as that of the series, but less steep, in overlapping relation with spaces between their overlapping portions; the lowermost baifle of the series having an upwardly projecting lip at its lower edge to arrest water flowing down its upper surface and a downwardly, rearwardly and upwardly extending part disposed toform a channel beneath the lower edge located to receive water dripping from suchedge, said channel and the angular space between the upwardly projecting lip and the adjacent part of the bafile being open at their ends for discharge of water flowing thereinto.

6 side margins and both end margins being upturned to form water-confining lips, and the other side margin being upturned to form a lip and doubled back and curled under the bottom, to form a channel having a bounding edge beneath and spaced apart from such bottom.
