Application filed November 30,1927, Seria1 No. 236,827. Renewed February 12, 193 1 In the removal of fumes from the fumeemitting contents of a vat, such as a metal plating vat or other chemical container, dlfficulty has heretofore been exper enced from 5 lack of ability to distribute the suction feed uniformly, and, accordingly, to uniformly eject fumes released, and it is the ob ect of the present invention to so effectively overcome this difficulty as to largely ellmmate tendency of fumes to escape into the atmosphere about the vat or container.
In greater detail, it is a further ob ect of the present invention to provide suction ducts or exhaust passages so arranged and communicating with the fume area in such a way as to insure substantially complete and effective elimination of the fumes regardless of variations in crosssection of the vat and also regardless of irregularity in the fume dis.- charge at different places over the surfaceof the contents of the vat.
With these and other objects in view as will in part hereinafter become. apparent and in part be stated, the invention comprises, in combination with a vat or container, means so located and disposed relative to the upper margins of the contents of the vat as to effectively exhaust from the areas above the vat the released fumes while leaving the vat open and free for access.
The invention also comprises certain other novel constructions, combinations and arrangements of parts as subsequently specified and claimed.
In the accompanying drawing, the figure is a vertical cross sectional perspective through a vat and exhaustion apparatus illustrating an embodiment of the features of the present invention.
Referring to the drawing in detail, indicates a vat or container of any well known or conventional construction designed and adapted to contain electrolyte or solution or chemical of a type or character emitting or destined to emit fumes. By fumes is meant to be included any noxious volatiles, vapors, gases or objectionable emissions likely to contaminate the atmosphere in the region of the vat.
Mounted on the vat, and preferably resting on the-upper edge'thereof is an exhaust housing or duct l'preferably retained against dislodgment on the 'upperedge of the vat by a pendent flange '2 surrounding the margins of the vat. The housing 1 is, of course, susceptible of a wide rangeof variation in construction, and is shaped to provide pas sageways 3 extending along opposite sides of the area immediately above the contents of vat 0, said passageways?) communicating with pipes 4, 4, leadingto a discharge pipe 5 which in turn communicates with any appropriate exhaust connections, not illustrated. V i
The housing 1 is arranged to havelits inner face located above 'the'side walls. of vat a, and the innerwall of the housing 1 is so located with respectto the vat as to preferably overhang a relativelysmall portion of the vat to leave a" clear intake port fo'r. slot ,to within the housing from the area immedi'- ately above the vat throughout the length .of the vat. No obstruction exists between the contents of the vat and said intake port. The inner .vertical wall of-the housing ineach 'in stance is, of course, susceptible of being con structed in various ways, one form ofwhich consists in the employment of an'inner layer or liner a for the housinghwhich liner is formed with a pendent wall b forming the inner wall of housing 1., The liner'd'and inner wall I) of'housing 1 is preferablehof material especially adapted to resist corrosion or other injurious actionof fumes, and lead has been found useful and effective as one type of material to'this end, f The inner wall 6, as will be observed, is detached, that is divided from the low'erhorizontal wall of the housing 1 and set slightly inward therefrom to provide'the intaking slot 6 leading to the interior of the housing. As wall 6 is preferably of bendable material, it is adapted to be moved inwardto overhang the space immediately above .vat' c. to a greater'or less'extent, and this variation in overhanging is variable in the length of the wall according to the requirements of exhaustion andthe consequent need for greater or less width of slot 6 at various places to insure l'ilO uniformity of exhaustion with the variable suction force employed. As a means of testing the desired or preferable location of each part of wall I), smoke may be released in the area above the vat c and the various parts of wall I) shifted and located until the exhaust position best adapted to insure perfect distribution and exhaustion from all points above the vat is attained. Of course, when referring to thewall b, all parts of the wall at both sides ofthe vat are had inmind, and it should be obvious that the shifting or variable location of the wall may be accomplished otherwise than byhaving the wall formed integral with the lining of housing 1 and formed of bendable or soft material. Thus, by the proper adjustment of the wall I) along both'sides of the housing 1, the speed of exhaustion is rendered uniform throughout the length of the exhaust duct, and it will be apparent that if at any time, by the introduction of new contents or otherwise, the materials within the vat c begin to'demonstrate a propensity to release fumes at one place greaterthan at'others, or at a different rate than formerly, the wall I) maybe shifted during the operation ofthe apparatus to such new positions as will provide and insure eifective exhaustion of the released fumes. The operator will naturally see that where the suction speed is too slow in the length of the wall 7), the wall will be moved inward to I increase the width of the slot 6, or, if the suction be too rapid, depression of the wall at the place of excess speed will reduce the wi'dthof the slot 6 and thereby govern the speed of exhaustion to render it uniform and effective. I p
I claim as my inventlon: I 1. In a metal treatmg container, an exhaustion duct for carrying off the injurious vapors, one wall of the duct being divided therefrom to provide an inlet for the vapors from the container, said wall being movable to vary the sizeof the inlet.
2. A metal treating container having an exhaustion duct to carry off the injurious vapors, the wall of the duct next the container being divided from the container along a determinate line to permit the free edge of said wall to be bodily movedto varythesize of the inlet to the duct. 1
3. An exhaust duct to be secured to a metal treating chamber, the wall of the duct next thechamber being divided in part from said chamber and off-set from its normal plane to provide an inlet from the chamber to the duct.
4. A container for the treatment of metal,
an exhaust duct secured upon the edge of said container, the wall of the duct adjacent the container being divided from'the duct and deflected outwardly from thexvertical relative to the duct to provide an inlet for'the vapors from the container. v 1
secured upon the upper edge ofthechamber,
the relatively inner'wall of the duct being in part divided from the duct and deflected from the vertical to cause the free edge of the deflected wall to overlie the interior of the chamber.
7 In exhaustion apparatus, the combination, with a' container or vat, of an exhaustion passageway housing extending along the side ofthe upper portion of the container and having the inner face of the housing above the inner face of'the vertical wall of the container, the inner wall of the housing being pendent and spaced from the lower horizontal wall of the housing "and thereby pro-'* viding an intake slot from the areafabove? the container to the interior of'the housing.
8. In exhaustion apparatus, the combination, with a container or vat, of an exhaustion passageway housing extending along the side of the upper portion of the container,
said housing having its inner wall pendent I from the upper wall of the housing with its lower margin spaced relative to the housing and container to provide an intake passageway to within the housing. I
In testimony whereof I aflix my signature.
