Lette/rs Patent No. 106,218, dated 1u- gust 9, 1870.
` IMPROVEMENT IN MITERING-MAGHINE.
The Schedule `referred to in vtheseetter Patent and making part of the same To all whom, it may concernel Be it 'know-n that "I,"ErnnA1M SHAW, of'y v'Iarr Farm, inthe county 'oiYenaugo and State of Pennsylvania, have invented .a new and improved Mitering-Machine; and I do hereby ldeclare that the `fol-` lowing is a full, clear, and exact description thereof,
which lwill enable others skilled' in the art to make and i use thelsa'me, reference being had tothe accompanying drawing forming part of this specification.
Figure 1 represents aside elevation of my improved mitering-box. t
Figure 2 is a plan view bfthewsame.
'Similar letters'of reference `indicate corresponding parts.; 't v" Thisinvention relates toimprovements in miterF in g-machines, and consists in the arrangement of parts,
4as hereinafter spccitied atmiter-machine of' extremely simple construction, but perfect in Vope-ration is thus produced.V r t i 4 A in the drawing represents the bed or table of' my improved mitering-machine. A
".lo its surface is secured aprojecting rib or ledge, a, against which the. stuff'to be mitered is placed.
From the hedA projects also a post, B, which carries at the endet a horizontal project-ing arm b a. swivel disk, Cf y This disk turns on -au arbor, c, which has its bearings in the arm b.
The armAb can be made in two parts, as in iig. 2, between which the disk can be clamped by means of a` screw, d,lorit may be made in one piece, and receive a suitable set-screw or pin for locking the disk in any desired position. 4
Through the disk C is fitted diametrically a oylin# dricalrod, D, which constitutes the stem or shank of the saw-guide E.
. The rodean turn in the disk, and can he clamped thereto .by a set-screw, e. I y
The guide E ismade in form of a slotted plate, or of two wires or open frames,.as shown.
` l It is evident that in the disk the saw-guide can be set at any desired angle, to cnt miters at forty-five or other suitable degrees, while on the axis of v the disk the guide mayalso be swung to set the saw ata slant, and thereby vary the pitch of the miter.
Having thus described my invention, \I claim as new and desire to secure by Letters Patent.- Y The arrangement of the slotted ring-guide E, provided with the shank or rod D, the disk C, turning on an' arbor, c, Athe clamp-arms?) b, clampscrews (l e, and post B,'as shown and described.A a l t EPHRAIM SHAV.
