SPLIT SHINGLE.

Application led August l, 1927. Serial No. 208,854.

. My invention relates to a split shake or shingle. In particular, it is an improvement upon the shingle disclosed in the application of Frank L. Dietz, Serial Number 153,889, filed December 10, 1926, and upon Mr. Dietzs process for splitting out these shingles.

lin operating according to the Dietz process, the shakes which are split out are always tapered, but occasionally, due to peculiarities of grain in a certain piece, or 1n a certain spot of a given piece, or due perhaps to inaccuracy of the splitter, the shakes will taper out to a feather edge and will, perhaps, leave a jagged corner, which renders the shake oi second grade. It is an object of this invention to provide a method of splitting, and to produce a shingle, in which the production oit such seconds is almost wholly elimihated, and a method by means ot which the thickness of the tip of the shakes or shingles can be controlled as accurately as the thickness of the butts.

A further object is the elimination of grossly irregular surfaces, though still retaining the naturall split appearance, whereby Ythe laying o the shakes is made easier, and wherebytheywill t more closely upon one another, and thus keep the roof ti hter.

y invention comprises the novel process and the novel product thereof, the product being illustrated in the accompanying drawings and the steps of the process being illustrated by diagrams, and both product and method being disclosed in this specificationy and more particularly delined by the claims terminating the same.

1n the accompanying drawings illustratinfr my improved process and product,

Figure 1 is a perspective view o a shake or shingle embodying my invention and made in accordance with my process.

Figure 2 is a side elevation of the same.

Figures 3, 4 and 5 are cross sections on the respective lines 3 3, 4-4 and 5-5 of Figure Qlat the tip, intermediate portion, and butt of a shingle.

Figure 6 is a plan view of a block, of which Figure 7 is a side elevation, and Figures 8 and 9, 10 and 11 are similarly plan views and side elevations, illustrating the several steps in my process.

ln this specification I shall employ the 'term shake i or shingle interchangeably,

for, as the description progresses, it will become apparent that my method is adapted to thp splitting out of true shakes which, proper uniiiorm thickness throughout, or to the splitting out ot true shingles, which are boards tapering from butt to tip. Broadly speaking, my invention relates to the establishment, prior to splitting, of the thickness of the board to be split, at each end; hence, if a shingle is to be split out in accordance with the Dietz method, it may be determined in advance just what thiclmess the tip will assume, or, if a true shake is to be split, the thickness ot the two ends oi the shake may be established before the shake is split out, so that it may be ot substantiall uniform thickness, and so that it will be su stantially plane adjacent the ends and upon both faces.

As in the Dietz process, when my process is employed in the splitting out of tapered shakes or shingles, they are split from the block tapering, so that no nishing action is required, so that all of the wood is used, and so that none is wasted.

According to m method, a block of suitable Wood, genera l one which splits easily, such as western redy cedar, is placed on end, and after the first or outside board is split 0H, the block, instead of being immediately upended as taught in the Dietz application, is scored across its end to deline the thickness of tip in the next shingle. Thereafter, it is reversed end for end and is split out, starting with the thickness of butt desired in the next shingle, and this split will run out and eventually run into the split started from the revious end, so that the thickness of tip in t e shingle will be that determined by the hrst preliminary scoring of the one end, and the thickness oi butt will be that determined by the splitting starting from the opposite end.

Thus, as illustrated in Figures t? to 11, inclusive, the block 1 first had a board taken oi of the face 12, and, subsequently, had the frow 2 placed across its end 10 close to the face 12, and a split 13 was started. The frow, however, was immediately withdrawn, and the split 13 extends only a short distance inward of the end 1G. The hlock is now upended, and, we nd it in the position shown in Figures 6 and 7, resting upon its end l0, the end l1 being uppermost. Note, too, that it is placed so as to out vertical speaking, are boards of substantially grain shingles. It is placed back from the corner 14 by an amount equal to the thickness of butt desired in the finished shingle, and the frow is then driven through the block from the end 1l towards the end 10.

Note that the splitting progresses in advance of the frow 2. The edge of the frow is not a cuttin tool and does` not shave the material. Rat er, the frow acts as a wedge to split or part the fibers of the wood in advance of it. In accordance with the Dietz invention, it will be evident that the split 15 now started bythe frow 2 will tend to taper 1 out toward the corner 16, but will eventually meet or intersect the split 13, whereupon the shin le will split off of the block and there willgbe formed a shingle which is substantially uniformly tapered from a perfect butt to a perfect tip. 1

The next step as shown in Fi es 8 and 9, is to place the frow along t e line 17 inward from the new upper ed e 16 by an amount equal to the thiclmess o tip desired in the next shingle. It is entered again, as seen in Figure 9, the new split 13 extending only part way of the length of the block. The frow is then withdrawn (although there is no reason why it mi ht not remain in place exce t as 1t woul tend to continue the split arther), and the block is then upended to bring the end 10 uppermost, as seen in Fi es 10 and 11. The ow is now laced bac of the edge 14', now uppermost,

y an amount equal to the thickness of butt desired in the new shingle, and is driven through the block as before, whereupon the split 15 will intersect with or coincide with the split 13', to form again a perfect and uniformly tapered shing e.

Referring to Fi res 1 to 5, inclusive, it will be seen that s gles thus formed have corners 14 and 24 at the butt, and which are both true strai ht ed es, and which are substantially ar el. oreover, the upper and lower sur aces, just inward of these corners, are substantially plane, for each of these surfaces has been defined originally by the entrance of the frow. Moreover, at the ti the edges 16 and 26 are true strai ht e es, substantially parallel to each o er an to the edges 24 and 14, and the surfaces immediately inward thereof are substantially plane, these too having been formed by the entrance of the frow.

The continuation of the split 13 can sometimes be observed, but this is of little moment. It does not extend far, and, in fact, is scarcely noticeable. In any event, as the shingles are laid in a roof, this split and an feather edge which may result therefrom 1s beneath one or two courses of shingles thereabove, and thus is held tightl against the wood beneath and is protected).7

It will be understood by those skilled in the art that the split 15 or 15 is accomplished by entering the frow, and then using 1t as a pry to split the fibers, and this operation frequently leaves slight transverse frow marks on the surfaces of the wood with which the frow contacts. These frow marks are illustrated at 18 in Figure 1, in a somewhat exaggerated fashion. They are not deep, and, as mentioned above, are scarcely noticeable. They are shown in the drawing in order that it may be understood how the shingle is s lit out, and as a guide to indicate from whic end the shingle was split out with the frow 2.

What I claim as my invention is:

1. A rived shake taperin from a butt to a thinner tip, the butt thic ess and the tip thickness being uniform throughout the width of the shake.

2. A rived shake taperin from a butt to a thinner tip, the tip and utt edges being straight.

3. A rived shake tapering from a butt to a thinner ti the two butt end edges being straight an parallel to each other, and the two tip edges being likewise straight and parallel to each other.

4. A rived shake tapering from a butt to a thinner tip, the two butt end edges being straight an parallel to each other, and the two tip edges being likewise straight and parallel to each other, and substantially parallel to the butt edges.

5. A rived shake tapering from a butt to a thinner tip, both the upper and lower faces, at butt and at tip, being substantially plane and in nearly splarallel lanes.

6.A hand-split ake, t e upper and lower faces havin the naturally split surface extending su tially from end to end, and both the upper and lower faces, immediately at each end, being substantially p ane.

7. A shake tapered substantially uniformly from butt to tip, and both faces presenting a generally rough, naturally split surface, each end of both faces being substantially plane, and merging into the rough surface.

8. A shake tapered from butt to tip, and having up er and lower surfaces naturally split, and its tip of uniform thickness across its entire width.

9. The method of splitting shakes which consists in splitting successive shakes from opposite ends of the blocks, initially scoring the end of the next shake at one end of the block before reversing the block to split off this shake from the opposite end.

10. The method of splittin shakes which consistsin scoring one end o a shake in the uppermost end of a block, reversing the block and s litting off this shake from the opposite an now uppermost end, scoring the end of the next shake in the same end and at the same side of the block, then reversing IIB the block to split oi the second shake from the opposite end, and so on until the block is consumed.

11. The method of splitting tapered shakes which consists in splitting butts of successive shakes alternately from opposite ends of the block, and scoring the tip end of each shake prior to commencing to split from the butt end.

12. The method of splitting tapered shakes from a wooden block which consists in enterin a wedge into an end of the block and space from its ed e by an amount equal to the tip thickness esired, to define the tip, reversing the block and driving the 15 wedge into the opposite end and at the same side of the block, and spaced from the edge by an amount ual to the butt thickness desired, forcing t e wedge endwise throu h the block, then similarly, in succession efining the tip and the butt ofthe next shake at the same side, but at opposite ends, and forcing the wedge through the block from the end opposite the first.
