COMBINATION VIOODWORKERS TOOL.

7 Application filed December 3, 1919. Serial No. 342,157.

To all whom it may concern.

Be it known that we, JosnrrrG. BERGER and ANTHONY G. GARDNER, citizens of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Combination Voodworkers? Tools, of which the following is a specifica tion.

The principal object of our invention is to provide for a woodworker a combination tool that will save him the labor of using an entirely separate tool for each measuring or gaging operation. A material reduction in the cost of our combination tool over that required for the purchase of completely separate units, will also benefit him. An, increase in the efliciency of the results obtained by the use of our combination tool, will also be apparent from the description to follow. v p

The preferred form of embodiment of our invention is illustrated in the accompan ing drawings, of which Figure l is a top plan view of the tool holder. Figure 2 is a side elevational viewof the holder containing the various tools employed for the measuring and gaging operations. Figure 8 is an end view of the holder showing the spidergage supported thereby in position to mark a curved surface. Figure 4 is a side view of the last mentioned end of the holder showing the surface gage in a position to mark a surface beneath an overhanging part. Figure 5 is a cross sectional view of the holder, showing the use of the router supported thereby. Figure 6 is a cross sectional view of the holder showing the router held thereby, in a reversed position to permit its free end to be used as a depth gage. Figure 7 is an end view of the holder, showing the scale'in position therein. And Figure 8 is a side view of the scale supporting end of the holder.

Throughout the specification and drawings, similar reference characters denote corresponding parts.

Referring to the accompanying drawings, the numeral 1 designates a tool holder preferably comprising a casting having a relatively flat base and a longitudinal, upwardly projecting rib or flange 2 preferably disposed along the middle line of said base. At its middle portion the rib 2 is braced by two parallel transverse flanges 8, 3 between which there is a vertical tubular portion 4:

' and braced by of said rib adapted to receive a router 5 a flange 5 By means of a set screw6 that is adapted to be screwed against said router through atransverse hole in the upper portion of the tubular portion 4. of the rib, said router is firmly held in said tubular portion of the rib for service as showni-n base of the holder 1 contains 7 below its tubular portion working end of the router a wide aperture 4, to permit the to project below it, or the other end of said'router, which is adapted to, be used as a depth gage, to pro ject below the base as shown in'Figur'e 6.

At one end, the rib 2 of the holder. 1'ter-. minates in a tubular portion 8 that is braced by a transverse, arch-shaped flange 9. This tubular portion 8 is adaptedto receivethe spindle l0 ofa surface gage ofthe common type. Along this spindle there ismoVa'blc adapted tobe r Figure 5. The I a head llwhich' carries a scriber 12, said spindle being firmlyheld Within the tubular portion 8 by a'set screw .13. The gage is thus supported for service in the most diflicult places. For instance, in Figure 3 the scriber 12 is shown in a position above-the base, with its curved end in contact witha spherical surface for accurate workas a spider gage when the holder 'lismoved over a flat surface. In Figure 4 the opposite end of the scriber 12is being employed to mark p a vertical surface 15 below an overhanging part 16 upon whose top surface the holder 1 is moved during the gaging operation. This figure thus illustrates how a surface, otherwise accessible with difliculty,,may be readily and accurately gaged by the'use of our improved device. Other surfaces, equally as diflicult to gage. may be readily and accurately marked with our improved tool.

The other end of the rib- 2 terminates in a double-flanged portion 17 that provides a vertically walled recess 18 adapted to receive a scale or rule 19 which projects above and below the base of the holder 1. This scale is firmly held in said recess by the hook-shaped end 20 of a threaded pin 21 which projects through said recess at one side of the scale. The inner threaded end of said pin 21 receives a thumb screw 22 within a hole 23 provided in the rib 2 to re ceive it. This thumb screw 22 may thus be readily turned on the threaded pin 2]. to draw its outer hook-shaped end tightly against the outer edge of the scale, to hold the latter firmly within the recess 18 at right angles to the base of the holder 1 for measuring purposes in conjunction with said base. The middle portion of the base edge is cut away topermit said scale to project below it. (See Figures 1, 2, 7 and 8). A set screw 22 assists in holding the scale in place.

It will thus be seen that we have provided a simple and compact gaging and measuring device comprising a scale, gage, surtacegage and spider The construction or the holder makes possible the easy and accurate gaging of surfaces ditiicult to reach by separate tools, while its simplicity renders its cost quite reasonable.

Having described our invention, we claim:

i, In a device of the type described, a casting having a relatively flat base, a longitudinal rib projecting upwardly from the middle portion or said. base, a vertical tubular member formed at the middle part or said rib, a rib bracing flange on eachside of said tubular member, and an element adapted to be supported by said tubular member, one end of which is adapted to be used as a router and the other end as a depth gage, said base having a hole through which either the routing or depth gage end or said element may be projected for use.

2; In a device of the type described a casting having a relatively flat base, a vertical tubular'member supported above one end or sai'dbas'e, a spindle supported by said tubular member'for projection above and below said base, a head carried by said spindle, and a'scribe'r adjustably secured within said head for use as a surface or router, depth 3. In a device of the type described, a

casting having a relatively flat base, a longitudinal rib projecting upwardly from said base, a vertical tubular member formed at one end of said rib, a transverse arch-shaped flange for bracing said tubular member, a spindle supported by said tubular member for projection above or below said base, a head carried by said spindle, and a' scriber adjustably secured within said head for use as a surface or spider gage above or below the base of said casting.

a. In a device of the type described, a casting having a relatively fiat base, a longitudinal rib projecting upwardly from the middle portion of said base, a double flange formed on one end of said rib, a scale within the recess formed by said flange, a pin having a hook end adapted to grip the outer edge of said scale, and a threaded end projecting through said recess on one side of said scale, into a cut-away portion of, said rib, and a thumb screw on the threaded end oi said pin, within the cut-away portion of said rib, to draw the scale tightly within said recess, whereby it may be firmly held at right angles to the adjacent edge of the base of said casting.

In testimony whereof we have hereunto set our hands this 29th day of November, 1919.
