DAVID G. ROGERS, OF GREENFIELD, MASSACHUSETTS.
lVIITERING-MACHINE.
SPECIFICATION forming part of 'Letters Patent No. 272,903, dated February 2'7, 1883.
Application filed November 3, 1882. lNo model.)
To all whom t may concern:
Be it known that I, DAVID C. Roenes, a citizen of the United States, residing at Greenfield, in the county of Franklin and Commonwealth of Massachusetts, have in vented a new and useful Improvement in Miter-Boxes, of
whichi the following is'a full and true specifica tion. f
The accompanying drawings show the invention, and forni a part of this specification, in which- Figure I shows a plan View of the machine, Fig. 2 a transverse section of same.
A is the bed-plate of the machine; B, the back against which the material to be mitered usually rests; C, the swinging lever, having on it iron posts, through which the saw passes, and which is adjustable horizontally, so as to be set at any angle with the back, up to fortyflve degrees. D is an adjustable arm or rest to hold the work when it is desired to out at an angle larger than forty-live degrees, or to cut a miter on segmental work.
In the miter-box which I- patented (No. 220,732) the wood to be sawed is placed against the back B, the saw in the posts or standards on the adjustable lever pivoted at the rear is swung around, enabling any out to be made, from an angle of forty-live degrees down to a right line; but no stick can be out at a larger angle than that, because the lever can never be swung around to more than that extent.
In various uses in carpentry and other woodwork-cutting moldings, stair-rails, frames,
&c.it is often desirable to cut the work at a longer angle than the miter-boXes admit as at present constructed. It is also very important to cut circular or segmental work for frames, patterns, dto., at different angles, which cannot be done on a common miter-box with any safety or ease. I accomplish this by my invention, which consists of a rest, D, attached to a segmental arm, E, which runs through the back B, and is supported by an arm or bracket, F, projecting from the back, and slotted to hold and guide the segmental arm E.
This arm E is also slotted vertically, andl through it passes aset-screw,0, into the bracket F, which holds it at any desired point. In
the back B is a recess, into which the rest D- 5c sits flush with the face of the back when withdrawn and not in present use.
The operation of my device is as follows: If it is desired to cut a piece of work at an angle larger than forty-five degrees, it is laid upon the table; but instead of placing itagainst the back of the machine the adjustable sliding rest is shoved out till the desired angle is made with the saw, when it is secured with the set-screw behind. Theangles at which the material can be cut may be varied indefinitely by swinging the adjustable lever, and also by extending it lengthwise.
Circular or oval work,which now can be only out with difiiculty in the machines as at present made, having no fixed support except at the point of the curve, where, when it is to be cut, is in my machine supported firmly by the sliding rest, which holds it at any pontof the curve to which it is adjustable by turning the set-screw in the rear. This, it will be per ceived, is a decided advantage overmachines' as now made.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. In a imiter-sawing machine, the combination, with the bed-plate A, having a back recessed for the reception of arest,D,and swinging lever G, of the segmental adjustable rest D, composed of parts D E, as and for the purpose set forth.
2. In a mter-box, the auxiliary rest composed of upright portion D and a horizontal segmental slotted arm, in combination with the bedplate, provided with an upright fixed back and a suitable fixed lug and a suitable clamping-screw, substantially as and for the purpose set forth.
