offfwhich I" am the owner. f

In the aforesaid patent valvesare located at the receiving and "discharge, ends; of the scupper, and; one/of the objects. of my invention is to provide novelimeans for mount. ing suohvalvesjg Asbothv'alves are; gap-able of shifting in one direction by the fluidpass ing through the, soupperand n ust, automate .caHy-returnv to normal or'rlosed position, it is irnperative that, they be mountedso as to swing very freely and,, when n their closed position; be; so. arranged th attherewil'l be no possibility of draftsor the elements entering the]building through the; souppers. 'M y invent'i'on' provides for these; functions in a g A V The discharge portionis adapted toy-be nor maily closed? by a vaflve; 171. The receiving very, simple and? efficient. manner,

A further object of my invention is to:

Referring .to the drawings, the scupger comprises'a, hollow Oasihglli), which is set 'intothe Wall 11 of any buiidihgor strueture at thefl'oorv line 1211 The scupp 'er is preferably given a pitch, as illustrated in. Figure- 1', to? insure proper-drainage from the: floor of 'the building; At the'inner side of'the,"

wall 11", the, soupper has ajlarge. receivingportion or mouth 13 adapted tohe nor maily closed by; the valve 14. The receiving portion 13 is connected by a: tapered inten" mediate portion 15 with the restrioted discharge portion 16'. As illustrated} the area of! the cross-section of thepassage in-thfe' receiving or mouth ort-io-n is considerably greater-' than that of the: discharge portion portion; is locatedfi with its bottom inner sur+ faceat or about the floor leveland. the dis:--

Difficulty isexperienced inali gningthe-holesforthese pins,- and in oases-where they are not'properly aligned thevaI-ves-wili have a tendency toastiek with Y Y disastrous results. I i' the valves are opened and stay open, the elements wilL enter and employee will stuffi them up thus frustrating the entire object ofinstalling the. soup pers. In; case 013 a fire in an adjoinin bui lding; the open soupper would; act as a hue and readily forman entrance for the flames: Ifi the valves of the'seuppers do not swing freelyat a timeef: em'eiqgenoy when it is desired to freethe'buildingof water,v the results again arewvery costly. The damper at the receiving portion is quite apt to be- 001116 damaged or broken. Mounted"as is disclosed in saidpatent', it would" be very iinpractioal and. costly to, install a new da-niperbecause the ends ofthepin on which it is mounted are entirely covered by the wall construction. The-valve for there iii ceiving portion in said patent has no seat.

The valve, therefore, has to fit very snugly 1n the casing to lnsure keeping 1t weathertight, and this naturally meansthe possie bility of it bin-ding.

The invention contemplates a simple and into the building. A. frame 19 having bolt holes 20 is secured bybolts 21 to the flange 18.

seats is such that, when the'scupper is in place in; the wall, the valve 1 2 will hang against the slope. A lug 23 is formedat the upperend of the seats adjacent the side walls of the receiving portion. The lugs have a notch 24 in which the projecting ends of the rod 25 in the valve 1a may rest. These lugs 23, as shown, are located close to the top wall of the scupper. When the trunnions, formed by the projecting ends of the wire rod 25, are in place in the notches 24, the top wall will prevent. their displacement.

As shown particularly in Figures 3 and 6,-

the width ,of the lugs 23 is about one-half of the width of'the seats 22. The result of this is thatthe valve lt has ample clearance in relation to the side walls of the receiving will open itand, at the sametime, 'it willv act as an effective barrier for anything coming from the outside. It can be readily seen that, by releasing the nuts. on the bolts 21, the frame 19 may be removed and anew valve easily-slippedin place. Ribs or bars 26 are shown extending from top to bottom of the frame. These ribs or bars 26 have rugged protuberances 27 extending therefrom varying distances into the room. The purpose of the ribs and protuberances is to protect the damper ltand to act as stops in preventing any object, such as a box or a. case, being placed against the mouth of the scupper and impeding the flow of water through the scupper.

. Th'emounting of the valve 17 in the discharge portion of the scupper will now be described. This valve which acts as a weather guard may be of heavier. construction than; thevalve 14:. It has a pair of trunnions 28 formed on its upper. corners.

These trunnions are mounted in short bushthe side walls.

At eaclrend of the frame, adjacent the side walls of the rece ving portlon, 1s a sloping seat- 22. The angle of the slope on these I ings 29 which, in turn, are mounted in notches in the upper parts of the side walls of thedischarge portion of the scupper. In its normally'c'losed position, the valve 17 is adapted to rest against a seat 30 formed in The seats 30 give the same advantage as the seats 22, that is, they allow the valve 30'to have ample clearance and do not impair its efiicient operation. The lower vlip of the valve may be offset-to cooperate with a like portion in the lower Wall of the discharge portion, and may also be weighted v to render it more effective. Aslotor openmg 31 13 formed in the upper wall of the discharge portion. In assembling, the valve is slipped throughsaidslot and its trun-' nions, with their bushings, are dropped into their respective notches. A closure plate 32 isprOvided for the slot, the purpose of which is to prevent any dirt from the wall dropping in and interfering with the action of the valve and also to confine the trainnions of the valve in their notches. The closure plate has its ends 33 bent down over the sides of the discharge portion and a pair of prongs 3 1, punched from the plate, are bent down and under the top wall to hold the plate in position. 1 Y

In some cases it may be desirable to form the frame 19 without the ribs or bars 26. This is illustrated in Figure 6. It will be obvious that one skilled in the art might make changes, in details and form, from the.

1. In a scupper, the combination of a hollow casing,.adapted to". be located in a wall at the floor level for -draining water from the floor; a frame removably secured atthe inner end of said casing; a series of bars across said frame, said bars having protuberances thereon to preventany object being placed against the inner end of the easing and closing it be and 'a-va'lve. pivotally mounted on said frame, said valve hein adapted to substantially close the inner en of the casing.

2. In a scupper, the combination of a. hollow casing, adapted to be located in a wall at the floor level for draining water from the floor; a frame removably secured at the inner end of said casing; a valve pivotally mounted on said frame, said valve being adapted to substantially close the inner end of the casing; a second valve adaptedto'substantiallyclose the outer end ofthe casing a seat formed in the casing on which'said second valve will normally rest in the closed position; an opening in the upper wallof the casing through which the valve may be slipped; and a closure for the same.

3. A scupper comprising a casing having,

, at its receiving end, a removable frame provided with a plurality of guards of varying dimensions for preventing obstructions being placed at the receiving end of the soupper; a valve mounted on the frame and free 1 ly movable relatively thereto in the direction 7 stantially close the outer end of said casing,

a seatformed in the casing on which said valve will normally rest in the closed position, an opening in the upper wall of the casing through which the valve may be slipped, and a closure for 'said opening.

5. In a scupper, the combination of a hollow casing, adapted to be located in a wall of a building at the floor level for draining water from the floor, said casing having a substantially large receiving portion with parallel side Walls, a portion tapering away from said receiving portion and a restricted discharge for said receiving portion, a valve pivotally mounted in said receiving portion, said valve having an area substantially that of the cross section of said receiving portion and capable of being opened to its full capacity in said receiving portion, a valve seat for said valve, a second valve adapted to substantially close the outer end of said casing, a seat formed in the casing on which said secondvalve will normally rest when in the closed position, an opening in the up- In testimony whereof I aifix my signature.
