Application ined :une 19, 192s. serial No. 117,079.

Split cedar shakesform not only a tight in appearance, `and for some types of houses are extremely desirable, either for the roof or on the sides, but .as naturally formedthey are not readily adapted to modern construew tion owing tothe fact that they are as thick atone end as at the other. yTapered shingles'V have long been used in roofs and on thel sides, but these have always been sawed onv both sides and not split, and consequently, having a sawed side outward, their appearancer is that of a manufactured article, and

they have not `thenaturally rough appear-` ance inherent in split shakes. Attempts have been madeto imitate this naturallysrough appearance by scoring the outer faces of' sawed shingles from the butt toward the tip, but such scoring, to be done economically, must of coursebe done by machinery,

which produces an appearance of uniformity' not consistent with split shakes.

Ita is my object, then, to produce` mechanism whereby tapered shingles can be sawed onone face to leave the naturally split outer face, thus `enabling' the construction :of a house accordingto modern practice, such as 1s employed in` shingling, yet having the naturally irregular split surface of shakes,`

j somewhat froina true plane at the end` farpresented tothe observer. i i f A further object is the provision of a machine for the purpose intended which `will permit the rapid and `economical `manufacture of such shakes or shingles.

A further object is the production of such a machine which isl inherently yieldable or flexible in the sense that it `will accommodate ation. i i y Otherobjects, and especially those which relate `to structural details',v will be apparent from a study of the following specifications:

lrnot to the split surface.

A further Objectis the provision of such.4 a machine which is adapted toy power oper-` In the accompanying drawings I have shown my invention in forms which are now preferred by me.

VFigureul is aplan view of a simple form ot' my device. f i i Figure 2 is aisection therethrough on the line 2-2 of Figure 1. n

.Figure 3 is a plan .View of va power ma# chine, and` Y f Figure 4 is a side elevation thereof.` It will be understood that shakes, usually split from western redcedarlogs and split with r vertical grain, are fairly uniform in thickness from end to end, and are in gen-` eral ofa fairly plane surface on both sides, except as the `various `sap rings somewhat break the surface. Occasionally their sur face -is cur-ved, owing to the proXimityo-f a They are fre-` quently split-to` a thickness of one-half inch."

or less,`butl for the purposes of this inven-` tion suchshakes would ordinarily notgbe split muchthinner than one inch, and might remain thicker. The length of such shakes for the purpose I intend them would be in the neighborhood of two feet or more.

With athickenss ofone inch and a length of two yfeetpandsplit from the logs as they are, the surface ofthese shingles would vary thest from the splitting wedge,`and this has been indicated in Figure Q. Itis therefore essential that theV thin or tip edges of the be minimized as much as possible, and so that the tips of the shingles will lie flush in the same course, andthus will be better adapted to receive thefollowing course and to permit the shingles in the succeeding course to lie close to the shingles below. I have therefore.` provided a means for positioning and i clamping the shakes upon a. carriage, and for carrying the carriage past the saw, the positioning means being so` arranged relative to the path of the saw that the thickness of the tip is Vemictly determinedin` each instance,

fand at each end of the shake. In this coni `nection itvmay he noted that it is immaterial whether the shake is'mounted upon a carriage which travels past the saw, or whether the saw ris moved through a shake held on a fixed carriage. The former construction is illustratedkherein, but it merely a reversal of this construction to carry the saw through the shake;y Ltshould alsobebornsin mind that vani ous types et. saws v may? be:V empbyed As shown herein, a carriage 1 is supported.. upon afsuitable table '.Il,.and,;is.guided bythe guides for rectilinear' movement pastv a saw. vThe saw shown herein is bandiera-.Wy S;
