To all whom it mac concern:

Be it known that Lldnvnn VLAS, a subject of the Queen of Holland, resid ng at Paterson, in the county of Passaic andState of New Jersey, have invented certain new and useful Improvements in Carpenters Implements, of which the following is a specification.

This invention relates to the art ofindieating the plane of cutting a rafter 'or the like so that the face left by the cutting will abut fiat against another rafter or the like to which the first rafter is to be joined, and it has reference particularly to that branch of this art which is concerned with indicating the plane of cutting where such plane is perpendicular to no side of the rafter, as in the case of the hip, valley, jack and cripple rafters of a roof. The carpenter, knowing the run and rise of a roof, can by of the scale provided on certain carpentefis squares determine theangle of cut for an inclined. rafter whose end is to abut another rafter face to face and which stands in the plan at right angles thereto; but when the thus inclined rafter stands in the plan oblique to the other rafter he has to depend on certain calculations which ordinary carpenters are unable and which in any event are more or less tedious to perform. The object of this invention, therefore, is to provide an implement whereby a line such as the plumb-cut being found, the line complementary thereto to represent the plane of cut may be easily determined.

The invention broadly consists in pair of rules pivoted together so that each is confined to move in a definite plane and gaging means on one member adjustable toward and from the plane of movement of.

the latter. For facility of description ll have designated the member having the gaging means as the body member and the other as the auxiliary member.

In the drawings,

Figure 1 is a perspective view of the implement;

Figure 2 is a side elevation thereof;

Figure 3 is a sectional view on line 3-3 Figure 2; a

Figure 4c shows an architects or builders plan of the valley portion of a roof frame; and

Figure 5 shows a rafter and the plumbout thereon and, in dotted outline, my implement in position for indicating the line complementary to the plini'ibcut.

The body member is shown as a rule it having an edge beveled oif at the back, at 7). At one end of this member is a screw bolt 0 arranged in a plane perpendicular "thereto and forming a pivot, and on this pivot is confined to move in a plane parallel to the member a the auxiliary member (Z. The member (2 may be secured in any angular relation to the member a by tightening the screw bolt; the member may hav r. longitudinal slot (Z to receive the screw bolt, whereby member d may also be adjusted longitudinally, as in certain cases will be found convenient.

' The member a; has a pair of transverse tr angular guides projecting from its front face, perpendicular thereto; grooves e in the adjoining faces of these guides and a. longitudinalslot f in the member a receive a tongue 9 which forms the aforesaid gaging means. This tongue is a fiat plate, and since the ways 6' are perpendicularto the member a said. tongue stands in aplane pen pendicular to and extending longitudinally of said member and is shiftablc in said plane so that its working edge y may a. ume different distances from the bacl r. of 1 .ember a,

The lower end of the member a, as shown in Figi-s. l and 2 l desigmite its basai end; in the present case it is formed by the outer or lower face of the lower guidec, which isperpendicular to the plane of membero. At the, rear end of the tongue its lower edge has a lug g which projects into coincidence with the plane of said face of the lower guide 0 (see Fig. 2).

The tongue or gage 9 may be held where adjusted by the set-screw 17b- The implement is used thus: Let a represent the alreadyascertained plumb-cut line found on a timber A, Fig. 5, which is to form the rafter A (shown also by the builders drawing represented in Fig. 4;) that is to be joined to the valley rafter B. The gage or tongue 9 is set in member a so that the plane in which its rear edge and the edge (5 of member a lie forms a predetermined angle (see 3) with the plane of member a (or, which is the same thing, with the plane of movement of member (Z relatively to a). This angle is determined from the builders drawing (Fig. 4) by setting the implement basal end down on the drawing in the angle between the two raftthe lines representing adjoining faces of the two rafters; the lug g assists in truing of joints appear.

the implement at this time to a perpendicular relation to the drawing. The implement 1 is then transferred to the actual timber (Fig. 5) and placed with the edge 7) of member a true to the plumb-cut w and the corresponding edge of member at ex tending across an adjoining face of the time ber, and a line is marked, as at y, on the latter face along the edge of member d. The lines :0 and y will represent a plane, and whatever the angularity of the plumbcut line relatively tothe timber this plane will be perfectly vertical or plumb when the rafter A is in place; that is, the end formed on said rafter in said plane will squarely abut the side of the valley rafter B. It will be seen that when the angle is determined as in Fig. 4, it fixes 'the angular position which member a will occupy when placed against the actual timber, and that that in turn fixes the plane in which the member cl movesin short, the plane of the cut. The carpenter may apply the imple ment to the same side of the actual timber as it is shown as occupying in connection with the illustration of said timber afforded by Fig. 4-, that is, the inner side; but a timber is usually sawed from near the end inward Fig. 5. shows the implement adapted to the outer side, the plane of the out not being altered because it will be apparent that the implement is in Fig. 5 reversed relatively to its position in Fig. 4 and abuts the opposite side of the timber.

To simplify the explanation I have here inbefore referred to but one edge Z). Both edges, 6 as well as Z), of member a will usually be beveled and be working edges,

and correspondingly both of the edges of" .planes for cuts whose apices are at either the right or left sides of timbers. Fig. 4 shows theimplement on the builders drawing at points where several different kinds The bottom; surfaces of the lower guide 6 and the 111 g, being in a plane perpendicular to t e member a, afford rests for the implement when placed on the drawing (Fig. 4) and thus insure accuracy in determining the adjustment of the gage 9.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In an implement for use in indicating the plane of cutting a timber cross-wise, the combination of a pairof rules pivoted together so that each is confined to move in a definite plane, and a gaging device connected with one rule to move rectilinearly toward and from the plane of movement" thereof.

2. In an implement for use in indicating the plane of cutting a timber crosswise, the combination of a pair of rules pivoted together so that each is confined to move in a definite plane, and a gaging tongue penetrating one rule and slidable therein rectilinearly toward and from the plane of movement thereof.
