GAGE-SLIDE FOR ROTARY CUTTERS.

SPECIFICATION forming' part of Letters Pat'eiit No.-278,815, dated. June 5, 1883. Application filed January '9, 1883. (Ndmodeh) To all whom it may concern:

Be it known that I, Monnrs L. ORUM, of the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Gage-Slides for Rotary Gutters, of which improvements the following is a specification. I

The object of my invention is to provide means for presenting stock to the action of a rotary cutter or laterally-cutting bit insuch manner as to insure the formation of a recess of any desired extent, and to prevent the splitting of the wood by the cutter on the exit side of its out.

To these ends my improvements consist in the combination of a sliding frame or rest and a gage having a recess corresponding in form and dimensions with the axial sectional outline of the cutter; also, in the combination of a gageslide having a recess which is a counterpart of the axial sectional outline of a rotary cutter, and a fixed stop adapted to abut against the side of the gage opposite to that against which the stock to be cut rests.

The improvements claimed are hereinafter more fully set forth.

In the accompanying drawings, Figure 1 is a view in perspective of a gage-slide embodying my invention; Fig. 2, a transverse section through the same at the line :1: x of Fig. 3; Fig. 3, a plan or top view of the same; and Fig. 4, a view 'in perspective, illustrating the char acter of the recess'made by a cutter in connection with which the gage-slide is designed to operate.

- To carry out my invention I provide a frame,

A, which is secured to the table A of a dove B against which the stock abuts, is secured to the bar B, its lower edge being flush with or slightly below the bottom of the cutter-head, and a recess, 1), which is, as nearly as may be, a counterpart of the axial sectional outline of the cutter, is formed in the gage in line with the axis of the cutter-shaft. Said recess admits of the gage being moved up to and past the cutter, while presenting a bearing-surface for edges. The position of the stock is regulated laterally by a stop, I), which is adjustable toward and from the recess b by a set-screw, If, working in a slot in the gage. A lever, G, pivoted to the bar B, serves, when swung downward, to hold the stock in position upon the rest, as well as to move the rest and the ,stock placed thereon to and from the cutter. It will be obvious that, if desired, the bar B might be dispensed with and the lever C be pivoted directly to the gage B; but, inasmuch as a'special gage is required for and in conformity with each of the different sizes and forms of cutters employed, I prefer to make the gage a separate piece, and to form it of wood, so that-the recess 1) may be accurately made by the particular cutter with which it is de signed to operate, and any injury to the cutter by lateral movement of the gage be obviated. The longitudinal extent of the cut to be made in the stock is regulated, as desired, by a stop, D, secured to the frame A at the end opposite that from which the stock isfed, said stop be ing adjustable for greater or less lengths of cut, and being formed in this instance of a set screw having a clamping-nut, d.

In operation, the rest and gage being 011 the righthand side of the cutter, the stock or block of stuff, E, which is to be cut is placed upon the rest with its side, e, in which the cut is to commence abutting against the gage B and one of wits sides at right angles thereto abutting against the lateral stop I). It is then clamped in position by the lever O, and the cutter a being rotated at a proper speed, the

by the stop D, when it is withdrawn and the stock, in which a recess, e, has been formed, is removed. Inasmuch as the gage B bears against the stock entirely up to and along the edges of the cutter, the ordinary tendency of the latter to split the wood on the exit side of the cut is obviated, and by the adjustment of the stop D the extent of each cut made is regulated to the exact length desired.

I am aware that a sliding bed adapted to support and feed stuff to a rotary cutter was rest is pushed toward the cutter until arrested the stock for the entire extent of the cutting,

IOO

known at the date of my invention, and such,

therefore, I do not broadly claim.

I claim as my invention and desire to secure by Letters Patent 1. The combination, substantially as set forth, of a sliding frame or rest and a gage having a recess which conforms substantially to the axial sectional outline of a rotary cutter, these members being combined for joint operation to afforda support for the stuff entirely up to and along the edges of said cutter.

2. The combination, substantially as set forth, of a sliding frame or rest, a gage secured thereto and recessed conformably with the axial sec tional outline of a rotary cutter, and afixed stop.

3. The combination, with a rotary cutter, of a sliding frame or rest, a gage secured thereto and'recessed conformably with the axial sectional outline of said cutter, a clamping-lever pivoted thereto, and a stop fixed with the capacity of adjustment toward and from the cutter to the table thereof 011 the side opposite that from which the stock is fed, substantially as set forth.
