BEVEL.

SPECIFICATION forming part of Letters Patent No. 769,325, dated September 6, 1904.

Application filed April 25, 1904.

I the same being an instrument which enables carpenters to gage any particular angle and thenby means 'of said bevel mark on a piece of board or the like a line which will indicate how the same should be sawed in order to fit I properly into the said angle.

' In the drawings, Figure 1 is a front elevation of a bevel with the blade closed. Fig. 2 is an edge elevation of the same. Fig. 3 is a front elevation of said bevel with the blade opened and arranged at an angle tojthe handle portion.

A is a handle portion. B is a blade. C is a pivot-pin upon which the-blade may swing.

The handle is split longitudinally nearly its 5 entire length, and the pivot-pin is located in the split end. The bladeB has a longitudinal slot B, and the pivot-pin C passes through said slot.

, ,D is a clamping-nut which, if desired, may

3 have a handle I), by which it may be easily operated. This clamping-nut is mounted on the threaded end of the pivot-pin C, so that the split end of the handle A may be clamped down onto the blade Bto set it at any desired angle. The blade B is by preference made slightly narrower than the handle A. Hence when the bevel is closed, as in the position shown in Fig. 1, the edges of the-bevel, and

particularly the point thereof, (shown in dotted 4 lines, Fig. 1,) are entirely sheathed and prevented from becoming bruised or injured. In

the upper end of the slot B of the blade I provide an enlargement B which performs the important function of allowing the blade B to be shifted laterally, so that either edge thereof may be arranged flush with the edge of the handle portion A when the blade'is arranged at an angle theretofor example, as shown Serial No. 204,816. (No model.)

in Fig. 3. This will enable the two outside edges of the handle and the bevel to present 5 precisely the angle which it is desired to gage. In Fig. 3 the dotted lines indicate how the blade B is shiftedlaterally relatively to the pivot C to enable the user to adjust the edge of the blade B so that it will be coincident with the edge of the handle portion. Obviously if means were not provided to permit the blade to shift laterally if the user should introduce the bevel into the angle in a frame and endeavor to arrange the two members A B so that they would bear against the two sides of the angle one side of the handle A would bear properly against one side of the frame, but the blade B would not bear against the other side of the frame excepting at its 5 extreme point. The result would be that if the operator should set the bevel in this position and then mark along the blade the said marking would not be absolutely accurate. It is to overcome this inaccuracy and to permit the operator to adjust the. bevel so that the side edge of the blade, as well as the side edge of the handle, will bear properly against the two sides of the angle that I have provided means to permit this lateraladjustment ofsaid blade.v Another advantage of this improvement is that when the user desires to mark a linesay from the point of theblade to its rear end or around to the end of the handle he may do so without encountering a hump adjacent to the handle end. Were this enlargement B not provided, it will be seen that the edge of the blade would lie slightly within the slot in the handle, so that the edge of the handle would present a round hump, which 5 would. deflect the pencil. By my improvement this is simply and efiectively overcome and the user may gage accurately any angle and draw a straight line the full length of the blade.

What I claim is In a bevel, a handle portion having a rounded end and slit longitudinally throughout the greater portion of its length, a blade of less width than said handle portion and arranged in the slit of said handle portion, a longitudinal slot in said blade, a pivot carried by the Signed at New Britain, Connecticut, this handle portion and passing through said slot 22d day of April, 1904. in said blade, a portion of said slot being widened to permit said blade to be shifted EDMUND SCHADE' 5 laterally relatively to the pivot to bring the Witnesses:

edge of said blade tangential With the rounded H. S. WALTER,

end of the handle. W. J. \VORAM.
