CUTTING TOOL. APPLICATION FILED MAR. 3, I916.

CUTTING-TOOL.
Specification of Letters Patent.
Patented Apr. 24, 1917.
Application filed March 3, 1916. Serial No. 81,776.
To all whom it may concern:
Be it known that I, HENRY W. ALLING- HAM, a' subject of the King of England, residing at Northenden, Cheshire, England, have invented certain new and useful Improvements in Cutting-Tools, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.
My invention relates to improvements in cutting tools such as are used in lathes and its object is to provide a simple and inexpensive tool which shall be as eflicient in operation as those made of more expensive material. With this end in view the invention relates more specifically to a composite tool, the body of which is made of inexpensive metal into which is set a cutting bit of high speed steel of comparatively small size.
In order that my invention may be thoroughly understood I will now proceed to describe the same in the following specification and then point out the novel features thereof in appended claims.
Referring to the drawings:
Figure 1 is a perspective View of the end portion of a tool which is made in accordance with my invention.
Fig. 2 is a side elevation of the whole of the tool of which a portion is shown in Fig. 1.
Fig. 3 is a plan view of the end of the tool which is shown in perspective in Fig. 1. Fig. 4 is a transverse sectional elevation of the tool shown in the preceding figures, the section being taken on the line 4+4: of Fig. 2. v
Figs. 5 and 6 are figures corresponding to Fig. 4 showing two modified forms of construction which embody this invention.
Like characters of reference are designated by corresponding parts in all the figures.
thereto.
The bit'is set at an oblique angle to both I the lon itudinal and transverse axes of the body 0 the tool which angles are carefully 10 designates thebody of the m1 which predetermined to get the best cutting effect and to make the tool as strong as possible to resist the strains which are put upon it in use. The inner end of the bit is seated on the bottom of the hole in the body portion 10 so as to further strengthen the structure.
The cutting end 21 of the bit is sharpened to the desired shape and its angularity in relation to the body portion makes it overhang the ends of the body portion. To provide further clearance, the end of the body portion is cut back obliquely as shown at 11 andQthe side thereof is cut away as shown at In the modification shown in Fig. 5, the body 13 of the tool is constructed to receive near its end, two bits 22--23 which are fitted into two oblique intersecting holes in such a way that their inner ends abut as at 24. In this case the end of the tool body is constructed with a double bevel 14 to provide maximum clearance.
The structure shown in Fig. 6 differs from that shown in Fig. 5, in that the bits 25-26 are fitted into two holes in the body 15, 1
which are not deep enough to intersect so that the inner ends of the bits abut against a part 16 of the tool body itself.
I intend no limitations other than those imposed in the appended claims. Tools made in accordance with this invention have the advantage of having the axes of the bits inclined in the proper direction for the most effective strength and cutting ability. As
both the tool bodies and the bits are made The expression high speed steel as used in the specification and claims is intended to cover broadly any suitable high speed cutting material, the material per 86 forming no part of my invention.
What I claim is:
1. A cutting tool com rising a relatively -massive body portion 0 inexpensive metal,
provided with a recess .neaih one of its ends,
tion, near one of its ends, the axis of saidhole being inclined in two directions to the axis of said body portion, and a bit of high speed steel of circular cross-section seated in and fitted intimately into said recess and permanently aflixed to said body portion, projecting beyond the end and one side of said body portion and largely surrounded by said body portion, the inner end of said bit abutting against the bottom of I said recess.
3. A cutting tool comprising a body portion of inexpensive metal, provided with a recess of circular cross-section, near one of its ends, the axis of said hole being inclined in two directions to the axis of said body portion, and a bit of high speed steel of circular cross-section fitted intimately into said recess and permanently aflixed to said body portion and projecting beyond the end andone side of said body portlon, the inner end of said bit abutting against the bottom of said recess, the end of said body tportion being beveled and the side thereo being cut away in the directions of incline of said bit.
In witness whereof, I have hereunto se't my hand this 2 day of March, 1916.
HENRY w. ALLlNGHAM.
