The Schedule referred to in these Letters Patent and making part of the same.

------To all whom it may concern: set, so that their lower ends resting either on the Be it known that I, JoHN BULLARD, of Hyde Park, to be sawed or the bottom of the box, the is pre in the county of Lamoille, and State of Vermont, have vented from cutting below the point desired. invented a new and useful Improvement in Mitre It is often necessary in and cabinet-work ; and I do hereby declare the following to be a to cut mitres at angles, varying, but slightly from full, clear, and exact description thereof, sufficient to those for which provision is made in the box, and this enable other's skilled in the art to which my invention requires the exercise of much care, with vexatious cal appertains, to make and use the same, reference being culation and loss of time. In the present invention had to the accompanying drawing, forming part of this provision is made for cutting these slightly-varying specification, and in which angles. - - Figure 1 is a top view of a mitre-box provided with The vertical frames, in which the saw-gates are fitted, my improvements, and are attached to the sides of the box by means of screws Figure 2 is a side elevation of the same. iii, which pass either through slots or enlarged screw This invention consists in the improved construc holes; and g g are screws swivelled to the sides of the tion of the mitre-box, as hereinafter set forth, and in said frames, and working into the sides of the box. the provision of a slide, having spring stops, a set These screws have portions to which a suitable screw to be used in cutting “spring” mouldings, and may be fitted, to turn the screw and thus ad adjustable gauges fitted to the saw-frames, to facili just the frames, and with them, the said gates, later tate the cutting of tenons. - ally.

This slide is marked with a scale A represents the bed or bottom of the mitre-box, of inches, and fractions throughout its length, or, at and least, for a short distance at one or both ends. Near BB, the sides thereof, having saw-channels a a, at each end of the slide is a slot, in which is fixed a spring the outer ends of which are placed vertical frames.

A wood or metal, with large openings c, to receive the notch may be made in the slide, as at h, to facilitate back of the saw, and open slots d, for the passage of its adjustment. the saw-blade. . To use this slide, it is adjusted to the desired posi The gates D must be of such length that when a tion and there fixed by turning the set-screw i, which, narrow saw is used, it will be so supported that its at its inner end, bears against the slide.

This screw is used To provide for the wear of the saw and gates, and in outting spring-mouldings, which are set on edge in for the use of of different widths, at any time, I the box, in a position more or less oblique, according make the gates vertically adjustable in their frames, to the adjustment of the screw, which presses against by fitting a set-screw, e, in the bottom of each slide. the side of the laoulding. Thus, by regulating the Instead of adjustment by means of set-screws, a slide, screw, the moulding may be cut at almost any desired f, which may be graduated, can be fitted to each gate, angle. This screw F can also be used for holding any by means of a screw passing througli a slot. By set moulding while it is being cut, by adjusting the screw ting this slide, (its lower end projecting below the gate.) so as to exert lateral pressure on the strip or mould the gate can be adjusted as desired.
