IMPROVEMENTIN MACHINES FOR CARVING AND ORNAMENTING WOOD-WORK.

Specification forming part of Letters Patent No. 91,410, dated J une 15, 1869; reissue No. 6,572, dated August 3,1875; application filed July :23, 1875.

' curved or angular knives or cutters secured to a cutter-head or mandrel, for the purpose and having the facility of penetrating wood, and also for cutting laterally or across the surface in any desired direction, according to forms of patterns placed upon the opposite or back side of the stuff to be cut, and which forms are moved upon or around a guide-point or roller, the center of which corresponds with the center of motion of the cutter, the object beingto provide a means by which various designs may be cut in the surface of solid pieces of lumber, for the purpose of forming panels or other articles, thus avoiding the necessity of using a variety of separate pieces to produce the design.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, which form a part of this specification, and in which- Figure 1 is a perspective of the machine. Fig. 2 is alongitudinal section. Fig. 3 is a cross-section on the line w w of Fig. 2. Fig. 4 shows a piece of wood partly cut. Fig. 5 is an edge view of the same with the former attached.

A represents the frame, upon which is placed the mandrel B, having attached to the outer end the cutter-head G, to which are fastened the curved or angular cutters or knives D D, the mandrel being driven by a belt runningon the pulley E.

The gage plate F, or its equivalent, is adjustable, and governs the depth of cut by a form for variable cutting, or by being fastened, by set screws 11 b, for cutting uniform depth.

The adjustable table G, with its arms H H, spring J, and guidepoint I, is controlled by set-screw K, so as tobe adjustable to dili'erent thicknesses of material, and to allow the cutter C to be entered at any part of the stuff to be worked, and to' allow the cutter to be withdrawn when the work is done; also, for entering and Withdrawing the guide point I from an open or slotted pattern, so as to work concentrically, at all times maintaining its position in line with center of cutter.

It will be observed that the relative diameters of the cutter and guide-point may be changed, either being larger or smaller than the other, as the nature of the work may demand.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The guide I, when used in combination with a molding or routing tool, whose axial line is identical with that of the guide, substantially as and for the purpose specified.

2. The arrangement of the cutter head G, with one or more angular or curved cutters, D, adjust-able gage-plate F, and adjustable table G, with its arms H H H, roller 1, and spring J, or their equivalents, all constructed substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this 22d day of July, 1875.

MYRON T. BOULT.
