Description

Patented Mar. Z1, 1939 UNITED STATES GAUGE Isaac T. Morris, Vancouver, British Columbia, Canada Application April 7, 1938, Serial No. 200,797

2 Claims.

This invention relates to a gauge.

It aims to provide an improved tool adapted to perform the function of various separate tools and for instance that of a gauge, level and plumb, rule, square, protractor, bevel square, try square, miter square, etc.

The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawing illustrating an operative embodiment.

In said drawing:

Figure 1 is a view in side elevation, partly broken away, of the improved gauge;

Figure 2 is a plan view of the parts of Figure 1;

Figure 3 is a detail section taken on the line 3--3 of Figure 1;

Figure 4 is a detail section taken on the line lI-4 of Figure 1;

Figure 5 is a view showing the invention in connection with a timber, functioning as a plumb, and

Figure 6 is a plan view of the invention in connection with a plank showing use as a bevel.

Referring specifically to the drawing wherein like reference characters designate like or similar parts, a saw is shown as having a blade I with a usual toothed cutting edge I I and with a usual handle I 2 detachably secured to the blade I0 as at I3. Said handle has the usual opening I4 to accommodate the lingers.

The straight edge of the saw blade I0 is calibrated as at I so that it may be used for measuring or as a rule.

A pivot element I6 pivotally secures a miter block Il to the blade of the saw and it normally abuts the forward edge portion I8 of the handle I2. Adjacent the pivotal end of the miter block Il, a protractor I9 is delineated in any suitable way on the saw blade Il) and the miter block may be freely moved to any desired angle on the protractor.

Said miter block I'l is provided with a spirit bulb or the like as at 20 whereby the miter block also constitutes a level. It will be noted that the blade Il] is provided with an opening therethrough as at 2|, so that the leveling means 20 may be observed in some positions. Such leveling means is adjacent the edge I8 so that it will be protected thereby and danger of fracture or injury minimized.

In order to operate the block Il and secure it at various angles, a link 22 is pivoted thereto at 23 and it has an elongated slot at 24 through which a winged screw 25 passes and which is screw threaded into the handle I2. Tightening of the screw will bind the link 22 against the handle and thus secure the block Il in any desired position. Particular attention is called to the fact that the link is adjacent the opening I4 of the handle, so that the hand engaging the latter may also engage the link, in the adjustment of the block, to give a more lrapid and accurate adjustment thereof and also so as to better hold it when the adjustment is secured and the next step is to tighten the screw 25.

In Figure 5, the combination saw is shown in use as a plumb, in combination with a structural element 26.

In Figure 6, the combination saw is shown in connection with a plank 21, functioning as a bevel.

It will be obvious, that in lieu of the block I1 and the remaining improvements being shown on one side of the blade only, that they may also be duplicated on the other side of the blade, if preferred.

Various additional uses will become apparent to the artisan.

I claim as my invention:

l. A tool of the class described having a blade and a handle extending therefrom, said blade having a straight edge, a miter block pivoted to the blade inwardly of said edge and normally disposed against the adjacent end of the handle, the outer face of the block being in the same plane as the adjacent face of the handle, said handle having a hand hole therethrough, rearwardly extending link means disposed against said faces and pivoted to the block and operable to adjust the block and having a portion disposed relatively close to the lower extremity of the hand hole for the purpose specified, and clamping means on the handle engageable with the link and constraining it to disposition in the position mentioned.

2. A tool of the class described having a blade and a handle extending therefrom, said blade having a straight edge, a miter block pivoted to the blade inwardly of said edge and normally disposed against the adjacent end of the handle, the outer face of the block being in the same plane as the adjacent face of the handle, said handle having a hand hole therethrough, rearwardly extending link means disposed against said faces and pivoted to the block and operable to adjust the block and having a portion disposed relatively close to the lower extremity of the hand hole for the purpose specified, clamping means on the handle engageable with the link and constraining it to disposition in the position mentioned, and protractor means delineated on the blade adjacent the pivotal axis of the block.
