Description
JoHNHPoNS, or BALTIMORE, MARYLAND, ASSIGNOR "ro HIMSELR, JOHN S. RUSSELL, AND HENRY voGLER, or SAME PLACE.
Lettrsram No. 87,703, dared Mwr'ch 9', 1869.
.llle Schedule referred to in these Letters Patent anxnaiing of the um. n
To all whom 'it mel/y concern Be it known that I, JOHN PONS, of the city and county of Baltimore, and State of Maryland, have invented a new and improved Mitre-Box; andl doI hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, reference being had to the accompanying'draw screws, t t, attached to the arms, and projecting through the slots.
The slots s' s' may be formed either in a 'projecting part of the board its/elf, or in a metallic plate, S, aiiixed to the board, as shown in the drawings.
Each arm O I0' is provided with a fixed Standard, c,
- and a movable. standard, c', both slit, to receive and guide the saw. I
The movable standard may be constructed to slide back and forth in a slot, u,`in the' arm, and to'be tixed in any required position by means of a set-screw, c, on the under side of the arm.
Each arm is also provided with a curved arm or rod, D, rigidly aixed to it, and extending through a slot vin the corner of the base-board, or a clamp, E; attached to said board, and capable of beingxed in anyreg quired position by meansof aset-screw, e.
The board o r plank to be sawn is placed upon the instrument, so as to rest upon the base-plate,- along the line of the letters A A A, 2, and against the side wall B B. .The arms yO O are then adjusted at the required inclination thereto, and liixed in that position by the set-screws e t t, or any` of them, when the operationof sawing at the required angle can be readily performed.
It is evident that it will not answer toV have the plank resting upon the arms O C. Hence they are made fiati between the standards, and are eountersunkin the baseplate, so as to bring the weightl of the plank on the board A, and allow the arms to move freely. j
The countersink is made in thetriangularform shown by the lines -a a a, so that `the arms can each move through an eighth of a-circle.
The two together will then move over-ninety degrees, and will gauge the plank to be sawn,'at any angle,
from nothing up 'to-ninetyl degrees.
The standards c c' are made to operate in the linejof theside wall .B, the latter being cut away at b Vb, to
accommodate them.
The edges of these standards are bevelled ofi', as l shown at t, so as not to project beyond the inner' face of the side wall VI do not claim, as my invention, a mitre-box, of any form, having but one' pivoted arm, operating like the arm C.; but, having thus described myinvention,
What I claim as new, and desire to secure by Letters Patent, is v- The adjustable mitre-box, herein described, consisting of the base-board A, recessed at a aa, and slottedY at s s', the side-.hoard B, being cut away at b, and two 'arms O O, pivoted in the slotss-s, workingv in the recesses, and each vprovided with'an adjusting-rod, D, fixed ,standardtg-and anv adjustable standard, c', all said parts 'being constructed and arranged to operate to' gether in the manner and forthe purpose herein set.
forth.
