T0 ALL WHOM XT MAY COL'GERN:

Be it known that we, WILLIAM S. WBEELI-mend SOLOMON E. BXCKFORD, of Franklin, in the county ot" Merrimne, end State of Nei;y Hampshire, havel invented certain newand useful improvements in Mitre-Boxes,- of which the following is a. full, clextr, and exact deseription,'reference beinghad to the accompanying drawings,v making part of this'sp'eciticntion, in which- Figure 1 is a perspeiztive View of enr improved mitre-box.

Figure 2 is n vertical section through the centre of theswinging sow-frame, and the end of the erm which supports it..

Figure 8 is'n sectional detail to be referred to. i

Our'invention consists in a, gnide-frnme for the son', so attached and pivoted to e standard that it can be swung around on an exis vertical to the pinne on which the work is placed, and clamped et any ongle required; the guide-freineyitself heingnlso'jointed so thnt it een he inclined to the sai-l vertical axis and clamped in place, thus forming o convenientmitre-boxv of 'simple construction, in which twoengles or mitre :md bevel can be served :it the sometime. i

To enable others skilled in the nrt to understand and use our invention, we will 'proceed te descrihe the manner in which we have carried itfont.' Y

In the seid drawings, A is n postor standard, the foot of which is secured to n bench, E, or other suitable pince. This standard isA mede in two pieces,v 4 :md-5, one of which, 4, is grooved and slides on the portion, 5, being secured in position nt the required 'height by means of n screw-bolt, e, which passes through a slot, b, (figs, 1 and 3,) and is furnished Awith n-vvoslier, c. From thel portion L projects on erin, C, of the form shown in tig. 1, the outer end ai being puede circular inthe form of :v1/disk, yand to this portion al is pivoted, by ineens oa. seren'pin,e, the'tep bnr D o? the gnidefrnme E, which carries n similar disk,f. At each extremity ofthebnr D is formed nidisk, g, to which are pivoted the side pieces of the'pilrame E, theextremiti'es .7i of which are of n ferm to correspond with that of the disks y. The gnidenfrztnre E is bifureated for the reception ef'the smv, (seen in red in iig. 1,) pieces or guides z of nood, or other suitable materiel, being secnred by screws a; to the outside et' the frame so ns to leave slits 6 of o width to nearly correspondwth the thickness of -thc blade of the sa-w. By removing these pieces z and slibstitnting others of c, different width, the Width et' the slits d may he varied yfor saws of vnrious thieitnesses; or it' n smv with n stiff bncl: is to he employed, pieces of n diiereni: form may be used, or the guide-pieces may he provided with slots, for the passage of the screws x, so that the width ofthe slits Bruay be regulated without retrieving the guide-pieces from thfrnrneV The gnidefframe E can be raised or lowered, in accordance with the thickness of the steek to be sawed, b v adjusting the height ci the portion 4 of the standard, ns before explained. To the upper end of the pin e is pivoted en eccentric clamp F, by depressing which theipin e is raised, bringing the disk f up against the under sident` the 'disk I thus lirmly clamping the saw-freine `E at the required angle for the mitre to be cnt, which is determined by h Ineens of the graduated scnlfej on the-,edge of the disk'd, and the pointer la en the bar D. It is evident that the sco-le may be made on the disk f, instead oi' on the disk d, if preferred When it is desired to out on a. bevel, the sow-freine llis clamped ot the required angl-ete n vertical. lline'hy menus of o clamp, Goof similar scale Z for the purpose of indicating the anglo. This scale may be ronde a-t either end'of the bnr l), or on either; of the disks g or h. n

The mitre-hos; above described is simple in its construction :ind notliable lto get out of order, end vili be found extremelvvconvenient for a greet variety of ivork, as the blade of the sin con be guided with great facility hy means of the bfurcnted frame E, so as to out at any desired angle n mitre orA it bevel, or both simultaneously.

What we Aclaim es our invention, :indde'siro to secure by Letters Patent, is

1. The guide-frnrneE, sb hnngend pivoted to n standard, A, that it con be swung nronnd en axis vertical t'o the work, and also inclined to the said vertical axis, whereby the proper direction con be given to the saw to out. :L mitre or :t bevel, or both simultaneously, suhstnntinlly as set forth.

-2 We also elnirn provdinfc,r the frame E with on index or ndices for iixing or adjusting its position 'around its vertical exis, or nt the required inclination for n initie or o. bevel, in combination with n suitable clamp or clamps, or equivalentVincchnnioril device for looking it when adjusted, substantially ns set forth.
