Serial No. 429,274.

My invention relates generically to lumbermill machinery, and more particularly to a device for discharging the stickers which are used to space the courses of lumber in a pile from each other, semi-automatically upon the pile as the courses are piled.

rI'his is a preliminary to the kiln-drying or stacking of lumber, and since in the course of Acuring or drying the lumber it is most subject to warping, cracking and the like if itis subjected to undue or uneven stresses,

it is particularly important that the stickers be evenly spaced and that each sticker lie immediately above the sticker supporting the ,15 course below throughout their lengths. It is the object of my invention to provide a feed or discharge means, whereby the placing of the stickers in exact position is accomplished semi-automatically and with great ease, thus 2U eliminating considerable labor and the uncertainties of the human element.

It is a further object to provide a device of the general character indicated above which may be easily adjusted to accommodate different lengths of luniber,that is, to deposit the stickers at such different spacings as may be desired.

A further object is the provision `of a piling system, including such a sticker-depositing mechanism, wherein the pile may be kept always in such position relative to the sticker magazines that lits upper course is at a predetermined level therebelow.

Other objects, and more especially such as f" pertain` to the more strictly mechanical details of my invention, will be discovered from a studycf the attached drawings, of this specification, and of the claims which terminate the same. 4G My inventioncomprises the novel parts of V"a'novel combination and arrangement thereo In the accompanying drawings I have shown my invention in a form which is now preferred by me. y

Figure `1 is a view of a sticker magazine, lookingptoward'the end ofthe lumber which is beingpiled, and showing parts in thepositions they would assume as a sticker is being discharged.

Figure 2 is a general view of the stickerdepositing mechanism, taken at right angles to Figure l, and showing the parts in their normal position.

Figure 3 is a transverse section online 3-3 of Figure l through a sticker magazine, parts being shown in the normal position, and F igure 4 is a similar view, showing parts in operative position.

As the device would normally be incorporated in a mill, the lumber would be piled upon a truck or car 9, mounted upon rollers or supporting wheels 90, by which it may be run along rails 91, carried upon an elevator platform 92. The elevator platform 92 may e supported and elevated in any suitable way, and merely as illustrative of one means which may serve the purpose, I have shown a chain 93, connected to the platform 92, and passing over a sprocket wheel 94, which may itself be connected to a suitable source of power (not shown) to raise the elevator, or which may be merely a guide sprocket wheel, the opposite end of the chain 93 passing to some other source of power. Adjacent the elevator platform is the working platform 95 and a feed table 9G, by means of which the lumber may be brought for piling upon the car platform 9. The individual boards l are illustrated in the drawings with the transversely extending sticker S between them, adjacent their ends, and at 'intern'iediate locations.

Above the elevator platform I prefer that overhead rails SO be supported, upon the beams 81, these rails 8() supporting the track rollers 82 carried in trucks 8, wherecn, by means of transverse bars or beams 83, the sticker magazine l is suspended in position transversely of the pile of lumber on the platform 9. By thus supporting the sticker magazines, they may be moved into and out of position as and when required, and their use may be dispensed with whenever it is not deemed necessary or convenient to employ them. Also, as will appear hereafter, it is possible more easily to adjust them in position with respect to the pile of lumber and with respect to each other.

rlhe precise construction of the sticker plungers 2 on the several magazines all operate simultaneously, and this, of course, ena

tails that the several guide means 3 and 30 be simultaneously operable. To accomplish this, and yet to permit the adjustment al-f ready spoken of in the spacing between the magazmes,1 provide a rod 6, adjustable in length, which `connects from oneinagazine to another. This may conveniently consist of a` pipe, of which different lengths are provided, the ends of the sections being secured to a fittingO, pivotally supported upon an arm 61,

secured upon theprimary rock shaft 4 and similar iittings()1 and arms 61', by means of which the connection is made to the several rock shafts 4, on succeeding magazines. To adjust the spacing of the magazines, then, it is only necessary to take out the section of pipe 6, and to bring the magazines together or to spread them apart and then to connect another appropriate length of rod or pipe 6. A telescopmg rod might be employed to advantage.

It is'believed the o eration of the device and itsadvantages wi l novir be obvious, and that no detailed description thereof will be necessary at this point. Obviously, changes may be made, within the scope of the claims, and still be Within my invention.
