4 Claims. 1

The present invention relates to improvements in ripping tools, and has for an object to provide a simple yet durable tool for ripping metal of various thicknesses.

The invention has for another object to provide an improved form of block or holder for the tool and a new form of tool, these novel forms cooperating together in a new relationship whereby the same may be assembled and disassembled more readily and more quickly and may complement one another in operation to produce a more effective tool for the purpose stated.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views,

Figure 1 is a side elevation of an improved rip-ping tool constructed in accordance with the present invention.

Figure 2 is a perspective view of the holder with the tool removed.

Figure 3 is a cross section of the holder taken on the line 33 of Figure 4.

Figure 4 is a bottom plan view, or a view taken from the left end of Figure 3.

Figure 5 is a top plan view or a view taken from the right in Figure 3.

Figure 6 is a side elevation of a modified form of ripping tool.

Figure '7 is a top plan view of the same.

Figure 8 is a bottom plan view of the tool shown in Figures 6 and '7.

Referring more particularly to the drawings, [5 designates an automatic tool shown more particularly in Figures 6, 7 and 8 and which will be hereinafter more fully described in its detail.

This tool or bit I5 is readily assembled to the holder or body block member is and has a suitable end or shank I! for receiving an air gun.

The holder I6 is a block of metal or other suitable material cut away to receive the tool or hit l5 therethrough, as indicated in Figure 1.

Top and lateral adjusting screws l8 and 20 engage the side bits [9, shown more particularly in Figures 3 and 4.

In the case of the automatic tool l5 of Figures 1, 6, 7 and 8, the air hammer shoves the tool for ward.

In Figure 3 the side bits l9 are shown as being adjustable toward and from one another by operation of the lateral adjusting screws 20.

They are also adapted after adjustment to be 65 drawn tightly against the holder 16 by action of the adjusting screws is. The adjustment of these side bits l9 takes up the slack on the bit 28 of the ripping tool. By loosening the adjusting bolts i 8 the side bits I 9 are freed to be moved toward or from one another by the rotation of the lateral adjusting screws 26.

Referring more particularly to Figures 6, '7 and 8 the automatic tool 15 is more particularly shown as having the bit 28 pointed or sharpened as indicated at 29. This tool is appropriate for cutting circles or making circular cuts. The back end of the tool is cut away and relieved at 3|]. The tool may be ground into shape of a diamond point chisel at 29 for the purpose of relieving shavings and cutting circles.

The air-driven automatic tool is shoved against the metal to be out. There is no scissor-like action in this automatic tool.

The small end 28 of the bit I5 is placed between the adjusted bits i9 in the holder IS with the extension resting on the top of the exposed holder bits is which extend from the high central portion of the holder l6 into the thin portion of such tool holder IS. The air gun causes the sharpened end bit 29 to be pushed against the metal to be cut, causing a forward ripping of the metal, the holder being moved forward on the line to be cut as the metal is ripped.

It will also be noted that the side bits i9 are adjustable on the cutting bit 28 and are adjustable so that the various thicknesses may be cut with different thickness of tools. The ripping tool of Figures 6, 7 and 8 is relieved underneath as at 30.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.

What is claimed is:

1. In a ripping tool, a block having low and high portions with a shoulder therebetween and a slot extending substantially vertically through the holder including the high and low portions thereof, adjustable side bits mounted in the holder having parts in both the high and low portions and with the parts in the low portion exposed through the upper surface of the low portion, a cutting tool extending through the slot and between said side bits and having a tool bit projecting below the lower surface of the 3 holder, said tool bit having an extension plate resting on the top surfaces of those portions of the side bits which are exposed through the upper surface of the low portion of the holder with the inner end of the extension plate abutting said shoulder.

2. A ripping tool as claimed in claim 1 characterized by the fact that the cutting tool is an air-driven automatic tool with the extension plate extending 'angularly to the axis of the tool to maintain th tool in a diagonal position through the holder.

3. A ripping tool as claimed in claim 2 characterized by the fact that the tool bit has a Web portion extending angularly from the axis of the bit beneath the late, said web lying between the side bits.

4. A ripping tool as defined in claim 3 further characterized by the fact that the holder has cut-away portions in which the side bits are movably mounted, with laterally slidin adjusting screws carried by said block and having threaded engagement with the side bits and adaptedto draw-the side bits tightlyagainst the REFERENCES CITED The ioliowing references are of record in the file of this patent:
