MACHINE.

SPECIFICATION forming part of Letters Patent No. 356,326, dated January 18, 1887.

Application filed August 31, 1 886.

Serial No. 212,335. (No model.)

walls of the post and preventing unnecessary 1 To all whom it may concern;

Be it known that I, MARCUS G. PATRICK, a

- citizen of the United States of America, re-

siding at Museatine, in the county of Muscatine and State of Iowa, have invented certain new and useful Improvements in Mitering-Machines, of which the following is a speeification, reference being had therein to the aceompanying drawings.

My invention relates to the wood-working machines which are used for mitering the ends of boards, moldings, or other parts of structures; and the invention consists of the construction and combinations of the parts of the machine, as hereinafter fully set forth and claimed.

In the drawings, Figure 1 is a plan View. Fig. 2 is a side elevation. Fig. 3 is a front elevation.

A B designate the base and back of a miterboard.-

G is a semicircular plate having the lugs a a, provided with screw-holes for attaching the plate to the base A, and having a circular opening, a, a horizontal slot, (1.", and a vertical slot, a

D designates a hollow post, the lower portion of which is made to fit neatly, but movably, in the opening a of the plate 0. The walls of this post are provided with the oppo site slots, 1), which slots are wider than the set of the teeth of the same to be used with the machine, and the posts and slots are of sufficient length to allow all required adjustment and movement of the mitering-saw.

E is a sleeve made to fit neatly, but so asto move freely, over the post. The walls of this sleeve are provided with opposite slots, b, open at the lower end of the sleeve, and these slots are wide and long enough only to receive the blade, but not the teeth, of the mitering'saw. At the upper termination of these slots b is a steel pin, 0, inserted through the slots in the post. This pin is made to fit neatly, but to slide freely, in the slots of the post, and the said pin serves the purposes of preventing the saw-teeth from striking or rubbing against the lateral play of the sleeve upon the post.

F designates a curved plate the upper edge of which is provided with the scaled notches 0, to receive and hold in place the pin d, attached to the lower portion of the post. This plate is provided with perforated lugs d, for

attaching the plate to the miter-board, as

the pin (1 in the required notch in the plate F,

and the saw inserted through the slots in the sleeve and post is held and guided so as to cut a miter on the required angle.

The parts of this machine maybe readily detached from the miter-board'and from each. other, and may be packed in a tool-chest in small space for safe keeping and for transportation.

What I claim as new in a mitering-machine, and desire to secure by Letters Patent, is

The combination ofthe plate 0, provided with the opening a and the slots a a, the plate F, having the scaled notches c, the slotted post D, having its lower portion fitted and inserted in the opening ct and provided with the pin (1, and the slotted sleeve E, fitted to slide vertically over the post, and provided with the pin 0, fitted to and inserted through the slots in the post, substantially as'and for the purposes described.

In testimony whereof I affiX my signature in presence of two witnesses.
