ROBERT E. LINHAM, OF MANSFIELD, OHIO; I-IERMIE LINHAM, EXECUTRIX OF SAID ROBERT E. LINHAM, DECEASED, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE LINI-IAM DADO MACHINE COMPANY, OF SAME PLACE.

MOLDING-CUTTER.

SPECIFICATION forming part of Letters Patent No. 472,679, dated April 12, 1892.

Application filed February 14,1890. Serial No. 340,473. (No model.)

To all w/tom zit may concern.-

1 3e it known that 1, ROBERT E. LINHAM, a citlzen of the United States, residing at Mansfield, 1n the county of Riohland and State of Ohio, have invented certain new and useful Improvements in Molding-Cutters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap- IO pertains to make and use the same.

My invention relates to improvements in molding-cutters; and the object is the pro- Vision of a cutter or bit which will makea long or short groove or channel in the mate- I 5 rial, or a long or short bead on the material, which channel or bead may be of diiferent angles.

A further object is the provision of a head or cutter which will cut the material with a clear or shear cut.

The present cutter is especially adapted for use in connection with the cutter-head for which I filed an application of even date herewith, bearing the Serial No. 340,466.

To attain the desired objects the invention consists of a bead or cutter comprising a cylindrical shank to adapt the cutter to the cuttor-head referred to and a curved foot havlng substantially smooth or plane faces, With a blade tapering from the shank to the extremity of the foot, whereby the blade will operate on the material with a shear cut, and said blade being curved to form eithera channel or head on the material.

In the drawings, Figure 1 representsa perspective View of a cutter having a curved foot to form a head on the molding. Fig. 2 represents a similar View of a cutter to produce a bead also, but not so high as the cutter of Fig. 1. Fig. 3 represents a similar view of a cutter to producea curved channel. Fig. 4 represents a similar view of a cutter for forming a bead. Fig. 5 represents a side View of a cutter for forming a long curved chan- 5 nel. Fig. 6 represents a perspective View thereof. Fig. 7 represents a plan view of a cutter for forming a bead, and Fig. 8 represents a similar view of a cutter for forming a curved channel.

Referring by numerals to the drawings, 1 5o designates the shank of my cutter, which 'is of cylindrical shape to adapt it to the cylindrical socket of my cutter-head before named, and the cylindrical shank adapts the cutter to the cutter-head before referred to.

and the cutting-edge tapers from the shank to the outer end of the foot, the purpose of which is to cause the cutting-edge to operate upon the material with a shear out. The foot is curved or shaped to form either a curved channel or a head on the material, which chan-v nel or bead may be of different lengths, as desired, and the blade may be arranged at dif- 7o ferent angles. In all the forms of cutter shown it will be seen that a throat or recess 6 is formed at the rear of the blade under the front part of the shank, to thereby clear the blade and allow it to have unobstructed operation throughout its entire length.

In operation the shank of the cutter is secured or clamped in the cutter-head with the cutting-edge in proper position to operate on the material to produce a bead or chan- 8o nel, and by means of the tapering blade the material is cut smoothly and easily and with a shear cut.

Having thus described my invention, What I claim is- The herein-described cutter or bit, comprising a shank and a curved tapering solid blade or foot having a beveled cutting-edge, and a throat or recess formed between the rear part of said foot or blade and the lower part of said shank, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.

ROBERT E. LINHAM.
