.'12 Claims.
The invention relates generally to ovenstructures and more particularlyA to voven structures wherein provision is made for baking or drying `lacquer, or enamel'protective or decorative coatings on the metal sheets from which can bodies are'formed, and it primarily seeks to provide an oven of the character stated wherein is included a. novel `form and arrangement of balefY wall structure 'effective to assure passage of the treating air through between the sheets, ratherthan in part through and in part about side edge portions thereof without contacting the coated face portions.
' In ovens of the character stated the sheets to be dried or baked are conveyed through the oven chamber on an endless conveyor, travelling vin generally `parallel spaced relation supported by bail-like members carried by the conveyor. Such ovens have chambers therein of uniform, xed' dimensions and at least as wideor somewhat wider than the widest sheets intended to be conveyed. In these ovens the treating air usually is introducedginthe bottom vand drawn away-at the top, and considerable difliculty has ybeenv ex- .perienced in obtaining desired uniformity inresults by reasonof the fact that freek space is pro-- f vided along the oven chamber at each side of l which there is included baille-walls of thechary acter stated, 'and novel means for adjustably mounting the walls so that' they can be'made to cooperateproperly with sheetsl of varied widths.
Another object of the invention isk to` providenovel adjustable. bottomv space "closing velements movable'with the baffle walls and eifectiveto 'pref vent'treatingair passing up'outside of the balewalls.
, Another object of the. invention is to provide bottom space closing elements of the character statedwhich are hingedly connected with the adjustably mounted wallsand with thenoven structure namanner for automatically causing themfto assume the proper cooperative relation (Cl. 34a-150) ,f y i to the'walls'fas movement of adjustment is im- Dartedlto'the latter..y y With the above andother objects inview that will hereinafter appear,` the nature of the inven- 5 tion vwill be more fully understood by following the detailed description, the appended claims and I theseveral Views. illustrated in the accompanying drawing.. l n v Figure'lis a vertical'cross sectional view illustrating anoven structure embodying the inven-l tion, anadjusted position of the bale Walls being shown in dotted lines;
. Figure 2,is a fragmentary horizontal section taken onthe.1ine'2;2 onFigure 1. V
-In this disclosure vthe invention is illustrated as embodiedV in a more or less conventional form of oven structure and i1; is to be understood that the inventive vfeatures maybe embodied in ovens of-.Various designs and shapes. The herein disclosed 'form of oven includes the usual bottom 5, top 6 and side or ilanking walls 1, dening a longitudinalchamber through which sheets are con-i veyed for air treatment while being. disposed in generally parallel spaced' relation transversely of the chamber. f f f Alongitudinal duct 8 is suitably supported at the bottom of thecharr-ber and is provided along its upper surface withapertures-Q through which v the treating air is directed upwardlyto be received through downwardly directed .apertures Ill intoa take-away duct 'l ly sutablysupported in theupper portion of the chamber in the manner clearly illustrated in'F-igure 1.
The invention is designed particularly for drying or baking lacquer, enamelor other protective or.r decorative coatingsbnlarge metallic sheets intendedtobe iorrnedinto canbodies. In such uses'y hotiar is directed through the treating 4,0, chamber for-properr treating contact with the coated .surfacesof thetravelling sheets, but it is f to Vbe understood thattheinvention may be embodied in fovens intended for other .types of air treatment of sheets.:
451 The oven structure herein. illustrated yincludes the usual .cross supports i2 whereon longitudinal rails I3 .are supported, 4and these rails serve to support the eiective iiight I4 of an endless conveyor which "may be of .any :conventional form including the usualbail-like supports I5 for holding Ythe travelling'4 sheets in ygenerally parallel spacedrelation.` ,y ,y
lin ,thev practical development of the invention there are provided side baille wall units I1 'disg posedzin.. spaced -relaton to the sidewalls of the oven structure and in parallel relation to the lateral edge portions of the travelling sheets. Each baille wall structure l1 is supported on a plurality of supporting and placing rods I8 which are secured as at I9 to the wall structures l'l and extend outwardly through the side walls l, being equipped at their outer extremities with handle portions 20. The extended ends of the rods IB are slidable in bearings 2| secured as at 22 to the oven structure. It will be obvious that'by manipulation of the rods I8 the spaced relation ci the baille wall structures Il can be varied at Will.
Stop members 23 are mounted on the cross supports l2 and serve to limit the inward movement of the baille Wall structures and thereby assure against interference of these structures withv the drawing that the baille wall structures and the bottom bailles or side space closing means are` arranged in independently movable, longitudinally aligned sets, the baille wall sets being arranged in close end to end relation as at 28, and the bottom baille sets being arranged in similar close end alignment as at 29.
It will be obvious that by positioning the baille wall structures il so that they will closely approximate the lateral edge portions of the travelling sheets, the bottom baffles 24 serving to prevent passage of air upwardly between said wall structures and the adjacent walls 1 of the oven, the treating air will becompelled to pass upwardly, through between the travelling sheets and will not be permitted to short circuit the travelling sheets and pass upwardly about side edge portions thereof.
The particular construction and arrangement of the bottom baffles 24 permit them to` partake of movement of adjustment of the side baille Wall structures Il and assure the desired distribution of the treating air regardless of the adjustment of said wall structures.
It is of course to be understood that the details of structure and the arrangement of parts` may be variously changed and modified Withouty departing from the spirit and scope of the invention.
