SPECIFICATION forming part of Letters Patent No. 426,767, dated April 29, 1890.

' Application filed June 7,1889. Serial No. 813,430. (No model.)

To all whom it may concern.-

Be it known that I, JESSE E. BUNDY, acitizen of the United States of America, and a resident of San Rafael, in the county of Marin and State of California, have invented a new and useful Miter-Box, of which the following is a specification.

My object is to facilitate sawing a kerf across a piece of wood at any angle desired, and also at the same time inclining the kerf vertically at any degree desired.

My invention consists in the construction and combination of saw-guides, a guide-carrier, quadrants, and a box, as hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- V Figure 1 is a transverse sectional view of the box, showing the guides and guide-carrier connected therewith. Fig. 2 is a perspective view of the complete machine in position, as required, for practical use in supporting a piece of Wood and applying a saw to cut a kerf in the wood.

A is the bottom, A the top, and A the ends, of a box made of wood, of any size desired. The rear side is closed at its end portions by fixed pieces B.

B isa door hinged to the front edge of the bottom A.

O are posts adj ustably connected with the ends A by means of clamping-bolts extended through horizontal slots in such a manner that they can be placed in position to support a piece of wood 0 placed on top of the box, as'shown in Fig 2.

D is the base of the guide-carrier, pivoted to the bottom A by means of a postA so that it can be placed at any angle desired,

D is a section of the carrier hinged on the top of the base D by means of hinges D The pieces D and D are straight bars of equal length. I

F are quadrants fixed to the ends of the carrier pivoted on the top of the base A, and F are pointers fixed to the ends of the hinged part D F are set screws that extend through the pointers and into the ends of the hinged part D in such a manner that the pointers can be clamped against the quadrants F to bind the hinged part D as required, to retain it in a fixed position.

G are slotted posts detachably connected with the hinged section D of the carrier by means of mortises and tenons, or in any suitable way, in such a manner that they will project vertically in the same plane, and adapted to admit a saw to be extended through them, as indicated by dotted lines in Fig. 2.

G2 is an auxiliary guide made of steel plate and adjustably connected with one of the guides G in such a manner that it can be raised and lowered relatively to the saw, as required, to aid in keeping the saw moving in a straight line while in operation.

H is a quadrant made of metal and angular in its cross-section. It is detachably connected with the base A of the box by means of sockets H fixed on top of the base in such a manner that they will admit and retain the ends of the quadrant after it has been extended through a mortise formed in the pivoted base D of the guide-carrier, and also, as required, to retain the quadrant in concentric position-with the center of motion of the pivoted carrier. sockets are turned aside to admit the ends of the quadrant, and then replaced to fasten the ends.

In the practical use of my miter-box thus constructed the guide-carrier D can be set at Buttons pivoted on top of the any angle desired relative to the quadrant H by adjusting it horizontally, and the sawguides Ginclined vertically by adjusting the hinged part D of the carrier, and when adjusted as desired, and a piece of molding or wood of any shape is placed on top of the box and against the posts 0 and a saw extended through the slotted guides, the wood can be readily cut to produce a miter-kerf of any diagonal and vertical angles required, and when the machine is not in use all the detachable parts can be placed inside of thebox and the hinged door closed to protect them.

. I claim as my invention- 1. In a miterbox, the combination of apivoted saw-guide carrier formed in two parts of equal length and the upper part hinged to carrier, for the purpose of guiding a saw diagonally and also vertically at the same time.

2. An open-sided box, a saw-gnide carrier D D pivoted to a box, a quadrant H, at taehed to the box or base and extended through a mortise in the end of the saw-carrier, quadrants I and pointers F attached to the ends of the guide-carrier, and saw-guides G, attached to the same carrier, constructed, arranged, and combined tooperate in the manner set forth.

A miter-box comprising an oblong box having" one of its sides open at its central portion and a door hinged to its base on the 15 other side, adjustable posts attached to the
