IMPROVEMENT MOULDING MACHINES.

TO ALL WHOM IT MAY CONCERN: v

Bc it known that I, GEORGE HUDSON, of Ellisburg, in the county of Jefferson, and :State of New York, have invented a new and useful Improvement in Machinery for Cutting Wood Mouldings and I do hereby declare that the following is a full, clear, and exact description thereof, which will enableothers skilled inthe art to make and use the same,refercnce being had to the accompanying drawings, forming part of'this specification, in which- Figure 1 is a side elevation of my improved machine..` for cutting wood mouldings.

Figure 2, a plan or top view.

Figure 3, a front end view.

Similar letters of reference indicate like parts.

This invention relates to improvements in machinery for cutting waved or serpentine wood inouldings, and these improvements consist in a vibratory rotating cutter-'head, having bearings in a reciprocating. frame, con nected with a walking-beam and other suitable mechanism for producing motion, as hereinafter described.

A is a supporting-frame, the general construction of Which, together with the gearing, is similar to that oi` the ordinary straight-moulding machines now in use. B is an adjustable table or side leaf, on which the strip 0f wood is laid for cutting the moulding a in the usual way. The table is raised or lowered, to suit the thickness of the moulding, by vertical screws b b, and the moulding is held up against the side of theframe hy an adjustable guide-bar, c, fig. 2. The feed-rolls d d rest inbearings on the' top of the framing, taking motion from a pinion, e, on the shaft of the pulley C, and are adjusted in their pressure upon the moulding strip by a bar, d', fastened to the cap of the bearing g, which bar is raised or lowered `by a set-screw, 7L. The 4'cutter-shaft D has its bearings t'z'in the upper end'of a reciprocating frame E, and receives motion by the pulley 7c from the large pulley F on the main driving-shaft Zat the rate of four thousand revolutions per minute. The reciproeating frame E receives its motion from a walking-beam, G, with which i't is connected4 by the pitman m, and

the reciprocating movement of the frame is made more or less for the purpose of regulating the depth ot' cut in the mouldings with the cutter-head z, by adjusting the walking-beam Gr to work with more or less leverage,

-which adjustment is eected by shifting the walking-beam in the hub et, to which it is secured by the set-scrcw n. 'lhe walking-beam Gis connected at the other end by the pitman m with a plate-crank, p, on the endet' the shaft of the cone-pulley H, which is belted to the cone-pulley H that takes its motion from the small pulley I4 on the driving-shaft Z which carries the fast-and-loosepulleys F2, which take motion from any suitable power. The pulley C that drives the feed-rolls receives motion from a small pulley, C1, on the end of the shaft of the cone-pulley H.

'The operation ot' the machine is manifest. The strip of wood to be cut for a moulding is sawed a little across the grain for waving patterns, and with the grain as usual for straight and plain work, to both of which my improved machinery is equallyapplicable, thus making one machine available for both purposes and all kinds of mouldings, according to its adjustment and the patterns ot' the cutter-head. By the regular reciprocating movement of the sliding-frame E and the adjustment of leverage 'of the walking-beam Gr, it will be seen that the moulding is cut to any depth required in the wave, and that the longitudinal curve in the wave can be varied in length and character as required.

Having described my invention, I claim as new, and desire to secure by Letters Patent- The combination of the cutter-shaft D, the reciprocating frame E, and-the walking-beam G, or the equivalents oi' them,or either of them, the said combination being so organized, substantially as described, that by its mode of operation the cutter-shaft D and the cutter-head z shall rise and fall while in motion to.. cut any required depth or curve in wave or serpentine wood mouldings.

I GEORGE S. HUDSON.
