BUTT AND casino GAGE.

Specification of Letters Patent.

Patented Got. 16, 1917.

Application filed October 2, 1916. Serial No. 123,279.

To all whom it may concern Be it known that I, Bonner PRICE STAN- pnrono, a citizen of the United States, residmg at Simla, in the county of Elbertand State of Colorado, have invented new anduseful Butt and Casing Grage of which the following is a specification.

My invention relates to improvements in gages, and the object of this invention is to provide a useful tool, by the use of which the correct measurements and markings preparatory to cutting mortises for door butts, and the marking preparatory to the cutting of casings to the proper lengths may be accomplished with greater facility than by the use of tools as heretofore made.

I attain these objects by the mechanism illustrated in the accompanying drawing in which Figure 1 is a perspective view of the entire tool. Fig. 2 is an end elevation particularly showing a sectional view of the body, and the guide formed at one edge of the body. 1

The gage may be made of metal or wood preferably of sheet steel. It consists essentially of a body plate 1 having a guide plate 2 extending at a right angle to the face of the body or plate 1. The body plate 1 of the tool has a stepped isosceles triangular opening 3 in the face of plate 1, the unequal side of which extends the greater length of plate 1 parallel and adjacent to guide 2. The equal sides of opening 3 are provided with notches the faces-of which are parallel and at right angles respectively to the unequal side of opening 3. All the parts are marked on their faces near their working edges with graduations indicating inches and fractions thereof. The graduations adjacent to the notched portion of opening 3 indicate the distance the notches are from the union of the two plates 1 while the graduations on each end of plate 1 indicate measurements to correspond with the stepped sides of opening 3. The gradua tions on the side edge of plate 1 indicate inches and fractions thereof from one end 7 of plate 1. The openings 1 in the angle of plate 1 and guide 2 extend at right angles to the face of plate 1 of varied depths from plate 1 as inch inch g inch and i inch. Any number of openings can be used; there are 4 shown in the drawing. The ends 5 of guide 2 extend at right angles to that portion of plate ,1 indicated at 6. The ends 7 of plate l extend at right angles to the side edges of plate 1. i

In using the tool for marking a door to indicate the lines on which to cut to form a mortise for a butt, place guide 2 parallel against the face of the door with plate 1 parallel against the edge of the door. A line drawn with a marker against the upper end 7 will give the upper end of the mortise. The location of the bottom end of the mortise is found by the use of the scale of inches on the edge of plate 1 and marked in accordance thereto; the width of the mortise is indicated by placing a marker into the notch in opening 3 which indicates the distance theinner edge of the butt is to be located from the face of the door. The tool is then drawn with guide 2 and plate 1 'maintained in contact with the face and edge of the door the length of the mortise to be cut. The depth of the mortise is indicated by placing a marker in the proper opening 4: and drawing the tool along the edge of the door the length of the mortise. T he notches in opening 3 are equally spaced from each side edge of plate 1. To use the tool in laying out a mortise on a rabbeted door jarnb, place the inner edge of plate 1 against the stop face of the rabbet, place a marker in the proper notch in opening 3. This when drawn the length of the butt will give the inner line of the mortise to be out place the tool, plate 1 on edge of the door and guide 2 on inner face of the door and place a marker in the notch in opening 3 near guide 2 that corresponds to the one used in marking the jamb. This will give the inner line of the mortise to be cut on the door.

This mechanism prevents the marker following the grain of the wood outside the desired line to be cut; its open construction allows a very accurate and quick adjustment of the tool to mark the inner line of the mortise.

In using the tool to mark a side casing preparatory to cutting to proper length, first cut the bottom end of casing to fit its abutment, then set the casing in its proper position placing the tool on casing with guide 2 held parallel against the side jamb to be cased and plate 1 flat on the face of the casing to be marked, then raise the tool until the end 5 of guide comes in contact with the head jamh of the opening to be cased; then by drawing a pencil or marker against the top end 7 of plate 1 the mark will show the proper length to cut the cas ing. The other side casing is handled in like manner with the other end of the tool up thus securing a uniform parallel margin On the head'jambs of all openings to be cased. v

.Vhat I claim and desire to secure by Letters Patent, is

1. A butt and casing gage consisting of a single piece of sheet material formed of two rectangular plates one a body plate the other a guide plate, at rightangle to each other, the body plate having a stepped isosceles triangular opening therein, the an equal side of said opening being parallel to the edge-formed by the union of the two plates.

"2. A'butt and easing gage consisting of a single piece or" sheet material formed of two rectangular plates, one a body plate the other a guideplate, at right angle to each other, the body having a stepped isosceles trian ular opening'therein, the equal sides of said opening having 7 equal stepped notches, the faces of which are parallel respectively to the side edge and each end edgeof the body plate.

3. A buttandcasing gage consisting of a single piece of sheet material formed of two rectangular plates, one a body plate the other a guide plate, at right angle to each other, each plate having in the edge forming the union of the two plates right angled openings extending varying depths into the guide plate.

a; A butt and casing gage consistingof a single piece of sheet material formed of two rectangularplates, one -a body plate the other a guide plate, at right angle to each other, theends of the guide plate forming shoulders to "Stlfllie .an abutment subst-an ti'ally as set forth. 7

A buttand easing gage consisting of a single piece of sheet material formed of two rectangular plates one a body plate the other a guide plate at right angle to each other th body plat-e projecting beyond the guide plate at-each end.
