UNITED STATES PATENT OFFICE.

MARCUS C. PATRICK, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR TO CHARLES E. BOND AND ROBERT IVILLIAMS, OF SAME PLACE.

MITER-Box.

SPECIFICATION forming part of Letters Patent No. 414,655, dated November 5, 1889.

Application filed March 18, 1889.

To @ZZ whom it may concern.-

Be it known that I, MARCUS C. PATRICK, a citizen of the United States, and a resident of the city of Minneapolis, county of Hennepin, State of Minnesota, have invented a certain new and useful Improvement in Miter-Boxes, of which the following is a specification, reference being had to the accompanying drawings. e

The primary object of my invention is to provide a miter-boxof simple construction which will permit cuts to be made at any angle to the horizontal as well as to the vertical plane with any kind of a handsaw. To this end I mount in a suitable frame a sawguide having a universal adjustment. In other words, the saw-guide is pivoted in both the vertical and the horizontal planes and is movable laterally on its supporting-frame. I also provide a sectional backing for the miterboX, each section being removably secured in the supporting-f rame. f

In the drawings, like letters referring to like parts, Figure I is a side elevation, Fig. II a cross-section, and Fig. III a plan, of my invention.

A is the supporting frame-work or bed of the miter-box. f

B is a horizontal shaft mounted in a suit-I able bearing on the front side of the same and provided with a vertical socket C, having horizontal and vertical slots b and b', respectively, and an annular ratchet c on a flange o', projecting from the front side of the socket C.

D is a vertical post mounted in the socket C as a seat, provided with a vertical slot D of suhicient width for a saw-blade and itsv set, with .or without backing, and having a laterally-projecting pin D, working in the horizontal slot b and engaging with the ratchet c for securing the post at any desired position in its seat with reference to a vertical plane through its axis at right angles to the bed A.

E is a sleeve loosely mounted on the post D and having a vertical slot e therein enlarged Serial No. 303,654. (No model.)

A, and fitted with a set-screw or eccentric f,A

for clamping the shaft fast to the frame at any-desired point.

G Gf, &c., are wooden sections composing the sectional backing of the miter-box, each of which is removably mounted in a groove or seat a, secured to the rear part of the bed A. These sections may be secured in their positions in any suitable way, as by the eccentric-cams H.

K represents part of a saw-blade in position on the post D.

The operation is evident. AIn virtue of the fact that the post D is pivoted in the socket C, the slot D maybe drawn to any angle with reference to the vertical plane, and in virtue of the fact that the shaft B, with its socket'C, turns freely onits bearing the post D may be turned to any angle with reference to the horizontal plane and be secured therein by the yoke F and its set-screw f. The material to be mitered is placed on the bed A between the post and the backing G G. The shaft B and the socket C may be moved outwardly on the frame A, permitting the passage of wider or narrower material on the bed A. It is evident that mitering can be done at any angle with this construction.

The lines L represent kerf-lines at an angle to the vertical plane, and L' kerf-lines at an angle to the horizontal plane.

The sectional backing is an important improvement, as any section can be removed and new sections substituted without disturbing the others. It seldom happens that a backing will wear out equally at all points.

Vhat I claim,'and desire to secure by Letters Patentof the United States, is as follows:

1. The combination, with a miter-box, of a saw-guide-supporting post provided with a projecting pin and a socket for receiving said post having a notched flange and a projecting shaft, substantially as set forth.

2. The combination, with the supporting horizontal shaftB and annular ratohet-ange frame-work, of a horizontal shaft, a vertical c o', vertical slotted post D, provided with Io socket having slots, as set forth, and a laterally-projecting pin D, sleeve E on said ratchet and a saw-guide mounted in the post, and yoke F, substantially as set forth.

5 socket having a projecting pin, substantially MARCUS C. PATRICK.

as specified. In presence ofl 3. The combination, with the supporting JAS. F. WILLIAMSON,

frame-Work A, of vertical socket C, having EMMA F. ELMORE.
