The object of this invention is the production of a tool designed for use in connection with carpenters T bevels whereby different cuts on common, hip, valley, jack rafters as well as the notch of jack or other rafters for the wall plates may be made in an easy and accurate manner without the necessity of the joiner having full knowledge of cuts made with the usual steel square.

To the attainment of the foregoing, the invention resides in the construction, combination and operative association of parts such as is disclosed by the drawings which accompany and which form part of this application.

In the drawings Figure 1 is a view showing the manner in which an end bevel cut is scribed by the employment of the improvement.

Figure 2 is a similar view showing the manner in which a side cut is made.

Figure 3 is a .similar view showing the manner in which a rafter is notched to engage a wall plate.

Figure 4 is a top plan view of the improvernent.

Figure 5 is a perspective view of the square employed.

. Figure 6 is a sectional view on the line 6-6 of Figure 4.

Figure 7 is a sectional view on the line` 7-7 of Figure 4.

As disclosed by the drawings, I make use of a channeled plate 1. The top of this plate is inscribed with the length and with the rise of rafters. One of the side flanges of the plate 1 has a screw 2 threaded .therethrough, the said screw having a milled head 3. The channeled plate 1 has one of its ends provided with lateral extensions 4 and is formed between the extensions with a central notch 5. The lateral extensions 4 are not flanged and have arranged on their inner faces, adjacent to their ends wing plates 6. The wings 6 are wider at their inner ends and from thence gradually decrease in width to their opposite or outer ends. The outer edges of the plates 6 are flanged upwardly, as at 7 and each of the plates presided with. @elongated site s that. with itsfianged'edgel "l`hr0i1"g.h. the S'LQLS Sntheyreare passed belts 9; whiili also ftla'ijgnl'gall4 Ythe lateral extensions l.ofV tlieplateadj acent l,to the outer 4'corners` tlreref: it Thebolts '9.'- are eesasedbr mais 10 ing milledT heads for binding the Wings-gir the lateral'extensions oftheplates wheirtlie said wings are arranged at a desired angle to permit of the scribing and edge cut on a rafter. The plate 1, at a suitable distance inward of the notch 5 is provided with a central elongated slot 11, and is further provided adjacent to its opposite end with an outstanding rest lug 12. y

As disclosed `in Figures 1, 2 and 3 of the drawings the handle portion 13 of a T bevel is received in the channeled plate 1 and is held thereon by the binding screw 2. The blade 14 of the bevel is loosely and adjustably connected to the handle 13 in the usual manner. This blade is arranged between the wing 6 and is received in the notch 5. As disclosed in Figures 1 and 2 both edge and side cuts may be made on a rafter 15 when the latter is scribed in a line with one of the wings 6 and with the blade 14 of the bevel. When arranged on one side of the rafter 15 the lug 12 has its inner face flush with the inner face of the blade 14 so that the device may be conveniently and properly positioned on the rafter. In Figure 1, the dot ted lines on the rafter 15 show the angle of the cut to be made through the rafter, while in Figure 2, the dotted lines show the upper and lower edges of the angle cut, or the angular pitch of the cut.

When notches for wall plates are to be made in the rafter 15, I employ an angle square 16 which is freely movable through the slot 11 and is, of course, adjusted to the line where the proper cut is to be made in the rafter.

The scale on the plate 1 provides for adjustments of the device to meet various requirements which will be determined by practice, and the scale in the use of the instrument.

The lateral extensions 4 of the plate 1 are provided with studs 17, adjacent to their inner corners and the inner edges of the wings 6 contact with these studs for holding the said wings in a proper rigid position on the said plate 1. The markings on the late 1 indicate the difference in length of t e ack rafters and the square 16 is designed to have one of its blades pass only through the slot 1l.

The foregoing description and drawings have reference to what I consider a preferred form of my improvement, but it is to be understood that I may make such changes therefrom as fairly fall within the scope of what I claim.

Having described the invention, I claim 1. A device for the purpose set forth, comprising a scaled flanged plate having lateral non-flanged portions at one end thereof, said plate at its last mentioned end having an elongated slot therethrough, a binding element passing through one of the flanges of the plate, and Wing members adjustably secured to the outer corners of the non-flanged portion of the plate.

2. In a device for the purpose set forth, a flanged scaled plate having an outstanding rest lug at the middle of one of its ends and having the other of its ends widened and noneflanged, said scaled plate having a longitudinal opening therethrough and a notch in the middle of its widened end, a binding element in one of the flanges of the plate, and angle wing plates having outer upturned flanges adjustably secured at the corners of the widened end of the plate.

In testimony whereof I aiix my signature.

OLAF BEPPE.
