KILN ACCESSORY Filed'April s, 1924 Patented Nov. 1l, 1924.
FRANK T. KELLEHER AND SAMUEL R. BROWN, OF BEND, OREGON.
Application filed April 3,
T aZZ whom t may concer/n e it known that we, FRANK T. KELLEHER and SAMUEL BROWN, citizens of the 4United States of America, residing' at Bend, in the county of Deschutes and State of Oregon, have invented certain new and useful Improvements in Kiln Accessories; and we do hereby declare that the following is a full, clear, concise, and exact description of the'invention, such as will enable others skilled in the art to which it appertains to make and use the same. l
This invention relates to improvements in kiln accessories, having for an object to provide a novel form of sticker, commonly employed in the kiln drying of lumber, whereby the lumber when loaded onto a truck or similar device will be spaced, in order that circulation of the heated air therebe veen may be effected, the invention having for an object to provide a sticker of hollow metal construction which when positioned between the lumber will permit of an even greater circulation of heated air therebetween, as well as afford a. number of highly advantageous features to be presently set out.
In the drying kilns now employed for drying lumber, stickers are employed for separating and producing air circulating ways between the lumber. These stickers are constructed of strips of wood, square or substantially square in cross section and preterabiy formed of fir or spruce, costing from ten to twenty vcents apiece. wWhile the stickers thus constructed will serve to space the lumber, they will, with usage upon an average of three trips through a kiln, become excedingly brittle and charred, thus entailing aE considerable loss by breakage with handling or unstacking of the dried lumber; also, the stickers7 will shrink unevenly and in consequence,- fall from between the dried or drying lumber, often timesl breaking and seriously interfering with movement of the lumber supporting truck. A further disadvantage of using the wooden stickers is that the same will cause uneven drying of .lumber because of the fact that those portions of the lumber adjacent or (,'ontacting with the stickers will not be reached by the drying heat, and there-fore, will result in the presence of wet spots in the finished lumber. Ey the use of our improved sticker, the above noted disadvantages are removed. The hollow metal sticker possesses 1924. Serial N0. 704,077.
ay maximum potential strength and will be seldom broken, notwithstanding its subjection toI rough usagegwfurther, should the saine be bent, it canbe readily and quickly straightened, Additionally, by reason of the stickers.
@ther .objects of the invention will be `in part obvious, and in part pointed out hereinafter.
ln order thatthe invention and its mode of application or use may be readily understood by persons skilled in the art, we have in the accompanying illustrative drawings, and in theV detailed following description based thereupon, set out one possi-ble embodiment of the same.
In these drawings:
Figure l is an end elevation of a truck having lumber' supported thereon and held in spaced relation by the improved stickers, and, p
Figure 2 is a fragmentary detail in perspective of one of they sticker-s.
Having more particular reference to the drawings, in connection with which .like characters of reference will designate corresponding parts throughout, the reference letter T-designates a lumber carrying kiln truck having vertically disposed side stanchions or arms s rigidly connected to the opposite sides thereof whereby to permit the stacking of the lumber Z upon the same, either in edgewise relation, as shown in the Figure l, or in horizontal positions, as may be requireds The lumber Z in being ystacked upon the truck T is separated, when stacked edgewise, as shown in this embodiment of the invention, into vertical divisions or columns, whereby the heated air in the kiln will be permitted to circulate through and between such ways and in consequence, be brought into contact with the lumber Z in course of drying.
To retain the lumber in these separated columns or divisions, our improved sticker preferably, substantially square in" cross4 f in; the'.v Figure :2.1' Becausei section, aslsliei of the hollow construction or formation of the tube l, it Will be understood that an"air` circulating Way Will be provided through the same, and in consequence, With' positioning of the improved sticker between the lumber Z, a` greaterivolume'ofdrying air will be permitted" to' circulate byv and' between such"` lumber, therebyA expediting the drying ofl'the same.y Furthermore, it Willbe understood that' becau'seof theV passage of heated air through?the'vv'ayvv 2 provided for` by the hollow sticker l, the sides of such sticker Willbecome heatedto a degree cor# responding yte the temperature ofnthe heated dryi'ng air! Within the kiln, and'` in conf sequence,y the metal of"` the sticker will servey to directly transmit heat to those portions of the lumberl contactingiWitli-the sides of sucli sticker Hence, such contacting portions ofthe lumber Will be etl'ec tuallyI dried, andiin consequencethe'pres-- ence of! Wet spots ,in lumber at 'thosefpoints engaged'by stickers Will'be avoided. In thisfconnection, it shouldvbefmentionedy that in the forms ofi stickers novv generally used'in .lumberf drying; uneven .drying of the lumber is brought. aboutbecause ofthe fact that those portions ofthe: lumber engaging orcontacting With-the sidesoflthestickers7 employed Will be prevented frjoinliav-ingthe proper drying heat appliedthereto, being borne in=1nindfthat theselstickers areof solid construction and formed of Wood It is to be alsounderstoodthat the construction of our improved sticker such as will render the ysame.ex'ceedingly durable, and therefore, prolong; the. periodoffusage of: the same;4 Breaking of the stickers during liandlingofftlie saine will be reduced to minimum; and furthermore,.warping or shrinkinglof' such stickersff as is'the case with the Wooden stickers noivfgenerally used, Will be. positively` prevented. Should, however, the stickers become'bent, because of extreme rough usage, the same, vot course, r
The tubing from which the improved sticker is constructed may be of any Well knownand approvedtype or.` grade, it being preferable to employ that form of tubing Where-in the jointure between the meeting ends of the same are spot-welded or similarly joined, in order to prevent the appearance or presence of seams upon theadj acentwalls thereof. In consefpience,- flush engagement ofthe stickers with the lumber upon all of'its Wallsavill be secured.`
A sticker constructed" in accordance With the invention, ofcourse, may be formed of diitlierent lengths, suc-h as conditions or preference may dictate, and in positioning the same betvfeen the lumber Z, the usual mei s fer securingA such lumber in its stac d'p'osition, may be employed, such-for example, tying chains 3 having the usual separable fasteners t'yinterposed'tlierein and a, contractile coiled spring 5 preferably interposed in one of said' tying ch'ains 3 whereby to secure 'a yieldable engagement or connectionas between such lumber and'said tying chains.-
Manifestly, the constructionshown is capable of considerable modification, and such modification as is Within the scope of our claims, We consider Within the spirit of our invention.
