Letters Patent No. 109,190, dated November 15, 1870.

IMPRQVEMENTIN MlTER-BOXES.

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

To all whom 'it may concern:

Be it known that I, J UsTIN Disvocn, of Meadville, in the county of Crawford and State of Pennsylvania, have invented a new and improved Miter-Box;

j and I do hereby-declare that the following is a full,

clear, and exact description thereof', which will enable others skilled in the art to make and use the same, reference being had to the aecol'npanying drawing forming part of this specification.

This invention relates to improvements in miterboxes; and consists in a combination, with a box for holding the stuli, of a saw-'clamp or guide, arranged for holding the saw above the article to be sawed, near the` end, and adjustable either to a vertical plane or to any oblique plane across the box; also adjustable to a perpendicular or any other angle with the box, the said box having a vertically adjustable bottom, and a secondary bottom made in two parts, which may be adjusted to suit the requirements of strips or pieces which have oblique sides oi' a dividing wall, all as hereinafter described.

Figure 1 is a side elevation of my improved miterbox, and j Figure@ is a cross-section ot' the same.

Similar letters of refereuce'indicate corresponding parts. d

A represents the two sides of the box, and B the bottom.

The latter is made adjustable vertically with the sides by means of the screws G andthe slots D in the sides A. j p

It projects beyond the ends of the sidesA and has a central longitudinal dividing rib, E, dividingr the space into two parts, in each of which is a false bottom, F, hinged or jointed at G, and beveled ont-hc under sides next the outer edges, asv shown, for the application of the wedges H for raising the said bottoms from the horizontal plane..

Said wedges are provided with adjusting screws, I'.

K is a saw-guide, consisting of' a plate of any lrind with a slot, L,- for the reception of the saw, in such a way that it will be held and guided for sawing the ar' ticle under it, the edge of the saw projecting from the said guide.

lhis guide is hinged at M to a plate, O, which represents part of a circle, and is` pivoted at P to oscillate horizont-all y.

QV is a clamping screw passing through a curved slot in the said plate, `and screwing into the box belo'w to clamp the plate for holding the saw-guide at any required angle relatively to the box.

This plate O may have a scale on the upper face to indicate the position of the guide relatively to the box I longitudinally.

It' is a segmental brace, jointed to the guide K at S, and arranged with a post, T, mounted on the plate 0, for swinging with v it, so as to be clamped against the said post to hold it and the guide at any angle.

VThe said brace is provided with a scale to indicate the angle of the guide.

The supports for the guide and adjusting apparatus are hinged to one of the sides of the box to admit of raising them to put inthe work.

It will be seen that by means of all these adjustable devices the article tol be sawed may be adj usted vertically to the saw, also, on its longitudinal axis, and that the saws may be adjusted to any required angle in a horizontal plane, also to any required angle in vertical plane.

Ihe sides of the box may be extended beyond the saw-guide, if preferred, suitable notches being made in vthem to make room for the saw.

Having thus described my invention,

I claim as new and desire to secure by Letters I'n-tent- 1. The ribbed bottoni B, and hinged false bottoms FF, applied together to a unter-box, as and forthe purpose described. l l y 2. The beveled and hinged bottoms F, adjustable by means of wedges H, as and for the purpose described.

' Witnesses: JUSTIN DEVOGE.
