HINGE MARKER, MEASURER, AND CUTTING DEVICE.

Specification of Letters Patent.

Patented Aug. 23, 1921.

Application filed March 2, 1920. Serial No. 362,792.

State of California, have invented new and useful Improvements in Hinge Marker, Measurer, and Cutting Devices, of which the following is a specification.

My invention has relation more particularly to a combination marking, measuring and cutting tool adapted for locating and cutting out seats for door hinges.

A main object of my invention is to provide a tool of simple construction, whereby hinge seats on doors and jambs may be quickly and conveniently located, measured and cut without the necessity of employing any other tools or measuring devices.

Another object is to provide a tool or device of the character hereinafter described, which may be readily adjusted so as to mark, measure and cut seats of difl'erent sizes.

A further object is to provide a tool in which the cutting and marking elements may be conveniently removed for re-sharpening and replacement.

Other objects and advantages will be apparent from the following description, reference being had to the annexed drawing forming a part of the specification, in which:

Figure 1 is an edge view of a door showing my improved tool in position preparatory to marking and cutting the seat therein, the dotted lines indicating how a seat 01 larger dimensions than the tool may be marked and cut.

Fig. 2 is a side elevation of a door showing the tool applied to the edge thereof.

Fig. 3 is a bottom plan View.

Fig. 4 is a transverse section on line 4.4 of Fig. 1.

Fig. 5 is a perspective view of one of the cutting elements.

Referring more particularly to the drawings, 5 designates a hollow substantially rectangular cast body having a flat base or table 6 and provided with integral depending flanges 7, one of said flanges having a cut-away portion 8 for the purpose of affording a hand hold when the tool is in use. Mounted on the outer faces of three of the flanges are flat cutting blades 9 and 9', the blades being of substantially the same length as the flanges against which they abut and of greater width. The lower horizontally disposed edges of the blades form cutting edges 10, the cutting blades being detachably secured to the flanges by means of spacing bolts 11, which engage threaded apertures formed in the flanges,each bolt being provided with a nut 12 to prevent an accidental loosening of the bolts when the tool is being used. For the purpose of permitting a vertical movement of the cutting blades, each blade is provided with a pair of elon gated slotted apertures 13 through which the bolts 11 pass when the blades are secured to the faces of the flanges.

The cutting blades are protected from acc dental injury by a metallic guard 15, which extends around three sides of the body 5, and it is held in spaced relation to the flange faces by means of the enlarged shoulders 16 formed adjacent the head ends of the bolts 11, the shoulders spacing and maintaining the guard a proper distance from the outer faces of flanges 7, so as to permit a free vertical movement of the cutting blades.

One of the flanges 7 on each side of the cut-away portion 8 extends beyond the lower edges of the other flanges to form lugs or bearings 17 for a pair of gage screws 18, which engage threaded apertures formed in said lugs. By means of the gage screws 18 the width of the hinge seat may be readily gaged, as clearly shown in Figs. 1 and 4 of the drawings.

The method of using my lmproved tool will be readily understood from the foregoing description. When it is desired to form a hinge seat on one of the vertical edges of a door or jamb, the gage screws 18 are first adjusted so that the distance from the cutting edge of blade 9 to the ends of the adjusting screws 18 will equal the width of the hinge that is to be secured thereto. Along the lower horizontally extending side edge of guard 15 is formed a scale 19 by which the length of the seat cut may be accurately gaged without the necessity of employing a measuring tool. If the length of the hinge is greater than the length of cutting blade 9', then after a mark has been made by tapping the upper edges of the cutting blades with a hammer, the tool may b moved downwardly the desired distance so that the final cut will be the exact length of the hinge that is desired to rest in the cutaway portion or seat formed on the door or jamb. After an adjustment of the gages 18, the operator simply applied the tool to the edge of the door, as shown in Fig. 1 and taps the upper edges of the cutting blades sufliciently hard to drive them so that the upper edges are flush With the upper face of the table 6 of body 5, the slots 13; permitting of such a movement of the cutting blades.

After the out has been made the Workman chisels the wood out of the seat and the hinge is ready to be applied. From the foregoing description it will be apparent that by the use of my improved tool the measuring and cutting of a seat for hinges will be greatly facilitated, the same being accomplished 1n the minimum of markin time and at a much less expense than by the old method heretofore employed.

What I claim is A device of the class described, comprising a rectangular base member having depending flanges formed along the sides thereof, each of three of said flanges having a cutting blade secured thereto, said blades being adjustable in a vertical direction, a

pair of gaging screws mounted in the re- 7 have hereunto subscribed my name this 14th day of February, 1920.
