In operation the slide member 58 is rested on the stone to be sheared. The
blades (ill are permitted to follow the detent and protuberances of the said stone. .flhen, the .actuator handles 58 are pulled, turning the cam shaftand urging the lobe thereof against thetie hart iii. This, in turn, clamps the chisels or' blades l against the flat surface of the slide member. l3,
holding the said blades.;-in a predetermined fixed position, corresponding to the contour. of the stone. After'the stone is sheared, the handles are actuated in areverse direction in order that the protuberance 118 may engage the right angul ar member 33. This, in turn, urges the c'hisels 4diupwardly against the force of the springs 26. Thus, the releasing operation is effected. In order to" guide thejsaid chisels further and to retainthe springs 26 in thedesired relative posiiion, a reduced'shank 6% is provided on each of the-said chisels 43 for the purpose of sliding in and out of the receptacle 2d;
' Itli's noted at this point that an identical construction" of chisels' and actuating mechanism therefor, including locking means and resilient biasing means, is provided on the lower stationary, cross member 22. In fact, the lower chisels andupper chisels-ccoperate following the general contour of the upper and lowersurfaces of the stone to be cut. Since the lower chisel construction is identical to the upper construction, adetailed description is deemed unnecessary.
Reference is now made to Figures '7 to 9, inelusive, wherein a slight modification of the in-- ventive conceptis disclosed. It is seen that a pair of'brackets 'lll are secured to the slide plate- !8 Tfand a platform l2 is secured between said bracketsfA plurality of fluid actuated pistons i are mounted on said platform and a bar it is secured to the terminal portion of 'each of the pis ton rods used in conjunction therewith. This bar 16 engages the'chisels or blades 40 for the purpose ofreta'ining the same in the desired adjusted position. Fluid pressure may be. applied from any conventional exterior source and conducted through the conduit 13 to each of the said piston construction it. This, construction described above, takes the place of the cam locking means describedin .the first embodiment of the present invention.
. The angle iron actuator 38 is rigidly secured to the shaft 80 and a handle means 82 is associated therewith for the purpose of actuating said actuator member 38. Any-suitable means may be employedfor journaling the said shaft 80 such as a pair of brackets 85 which are secured to the slide member 18. The operation of the chisel rocks contour following features of this embodiment of the present invention are identical to those features' described hereinabove. 7
While there has been illustrated and described preferred embodiments of the present invention capableof performing all of the specifically men tioned objects as well as ancillary objects, it is apparent to those skilled in the art that various i shaft journaled" in 'said' slide-"members engage-" for'lockin'g and lifting said blades, finc'lud' I s'aid cam shaft"to 'saidiprotuberanc s durin changes includin omissions and additions may be made herein without departing from the spirit of the invention. Accordingly, limitation is sought only in accordance with the scope of the following claims.
