Fig. 9 is an end view of the swingable mitre member as seen from line 99 of Fig. 6.

Referring more particularly to the drawings the device is shown as comprising a frame having upright blade supporting and guiding means, indicated generally at II]. The upright blade supporting and guide means are spaced apart and each comprises a pair of channel members I I with the closed sides I2 facing each other and spaced apart. Spacers are provided between the channel members I I, there being a spacer I3 adjacent the lower end of each of the upright frame parts and a spacer I4 intermediate the ends of the respective pairs of channel members, said spacer I4 serving as stop means for limiting downward movement of the movable blade which will be described more particularly hereinafter. The spacers I3 and I4 are welded, brazed or otherwise suitably secured to the adjacent channel members.

Support means for the upright blade supporting and guide means or frame parts is provided and comprises a base formed of oppositely arranged angle members IB, one side I! of said members being in abutment with the adjacent flanges of the respective channels I I and welded, brazed or otherwise secured thereto, the other side I8 of the angle members I6 being substantially horizontal and spaced upwardly from the lower end of the device. At the ends of the angle members I6 are end pieces I9 which extend across the adjacent ends of both angle members I6 and are welded or brazed to adjacent parts thereof. A stabilizer is also provided at the front of the device and comprises a generally U-shaped strip of metal 20 which has its arms secured to the end pieces I9 of the base by bolts 2| or by other suitable means.

Adjacent the upper ends of the upright frame end portions 26 received between the channel members II of the respective frame parts and secured in position by bolts 21, said end portions 26 extending outwardly of the adjacent frame, parts.

It is to be noted that the channels of each upright frame part are spaced apart, by spacers I3 and I4, a distance slightly greater than the thickness of the blades, andhence thin shin anot 3 shown, are interposed between each side of the blade 24 and the bottom walls 12 of said channels.

The bolts 21 are received in openings provided therefor in the blade 25 and the lower bolt holes in the bottom walls l2 of the channel members ll, there being other holes 28 spaced upwardly therefrom in said walls I 2 so that the blade may be secured in a higher location if necessary to accommodatelarge bricks, blocks or the like.

The blade 25 is provided with two sets of longitudinally spaced holes 3! and 32, the respective holes of each set being laterally spaced apart.

These holes are for reception of bolts 33 for se-- curing reinforcing angle members 34 to the sides of the blade, said angle members extending'longitudinally of the blade between the upright frame parts Ill. The angle members 34 have their out wardly extending flanges adjacent the lower edge of the blade but spaced from said edge so as not to interfere with the effectiveness of the blade when. cutting.

The blade 25. isprovided with sharpened cutting edges 35 along each side edge so that the blade is reversible, and the respective sets of holes 3| and 32 permit suitable attachment of the reinforcing angle members 34, depending upon which cutting edge is-being used.

The movable blade is similar to the hereinabove described blade and the'cooperating cutting edges of said blades are in substantial alignment with each other. The reinforcing angle members 34 for the lowerv blade are attached by means of the lower set of holes 32so that the operative cutting edge of the movable blade will extend a suitable distance above theoutwardly extending flanges of the angle members 34 which are adjacent the cutting edge being used. The angle member ends are spaced inwardly somewhat of the adjacent channel members to provide operating clearance.

Duetothe fact that the. channelmembers H are spaced slightly apart a greaterdistance than thethickness of the :blades, the movable. lower blade will freely slide upwardly and downwardly between said channel members in the spaces 31 between the channel members of the upright frameparts and will not bind if said blade should tilt somewhat.

Each of the blades iiiisprovided with a small hole 38 adjacent each of the corners thereof for reception of the. hooked ends of springs 39, the

opposite ends of said springsare also provided with hooks whichv are receivedin openings-providedtherefor in anchor ears 4!]. welded or otherwise. suitablysecured to the respective pairs of channel membersv llcomprising the upright frame parts ID. The springs 39 serve to urge thev movable cuttingblade downwardwith substantially balanced force.

Means for moving the blade upwardly is provided andcompris'es a'jack 42'; shown as being a hydraulic jack; which has a ba'seL43 secured to the'flanges Itl'bybolts 44 which are'receivediin" Referring more partioularlyto Figs: 6 to Q inelusive, the device is provided with a receiving tray 55 which comprises a sheet of metal or other suitable material and receives pieces of bricks, tile, blocks or the like which have been cut off. The tray is provided with bolts 56 which are countersunk and welded or brazed to said tray. The bolts 56 are received in holes provided therefor in the outwardly extending flange of the angle member 34 at the back side of the movable blade;

To the outwardly extending flange of the front angle member of the movable blade is secured a mitre tray 58 having bolts 59 secured to said tray 58 in the-same manner as the bolts 56 are secured to the tray 55. It is to be noted that the trays are secured'to the upper sides of the respective angle member flanges.

Adja'cent'the endof one side edge of the tray 58 is'anear 68 having a bore therein for reception of a rod 6| which extends along said tray edge inupwardly spaced relation thereto. Adjacent the other end of said edge is a similar car 62 which, however, is spaced fromthe adjacent corner of the-tray-so as-toaccommodate a collar 63 which is securedtothe rod 6| by a set screw or the like, not shown. At the other side of. said car 62 is another collar 63awhich is similarly secured to said rod. The rod is thus held against longitudinal movement.

Slidableon the rodfil is anarm l0 whichhas an end portion N, Fig. 8, turned about said rod in slidable engagement. therewith and a winged screw 12 is provided in said arm for securing same against longitudinal movement on therod so as to hold the arm in adjusted positions. It is to be noted that the arm is movable-toward and away from the movable blade 25 in substantially parallel relationship at all times.

Adjacent tothe free end of arm 'Hlis a mitre member 14 which'hasan upstanding screw 15 secured thereto and which extends upwardly through an opening provided therefor in said arm 10. Thus the mitre member 74' is pivoted to said arm and said member is held in pivotally-adjusted positions by a winged nut' 16.

Mitre member 74-is provided with an upturned flange .18 adjacent its outer end and when the flange is parallel-with the blade 25 the side'thereof away-from-said blade'engages alaterally extending part 19 of the arm-Iii; The mitre member 'l4-is also provided with an'edgeSO-at a 45 angle totheflange lfl and when-the edge 8i} corresponds with the adjacent edge of the part 19 the flange l8-is-at a 45 angle to theblade 25. It is to be understood that mitre member 14 may be adjusted to other desired angular: positions and said member is securable in all the variousadjusted'positionsby'the nut 16! The mitre: arrangement provides for uniform angle cuts.-

A pad of spongerubber'or. other'suitable resilient'materia'l is disposed on the tray 58 beneath the arm lil' and mitre member 'H l so that bricks or other articles to be cut may be placed thereon. The upper surface of the pad is below the sharp upper edge of the cutting-blade, as
