This invention relates tocandy machines and more particularly to machines for dividing bars into segments, although it maybe employed with equal advantage for other a It contemplates more especially the pro.-

vision of means for dividingslabs of candy into bars of predetermined size ithout the subjection tl ereof to cutters or other undesirable expedients.- p i l 1 Known slab d'vidersresort to cutters and similar expedientswhich are not altogether satisfactory in that such devices require intermittent movement of theslabs to permit actuation of the cutters at predetermined intervals of rest. lhis-nece ssarily involves a complexstructure which is not conducive to the bestresults, 1

It Further, productionisi retarded consider ably due to the necessityof providing inter.-

emittent motion in'operating machines 1 of such-character, As a consequence thereof, it I is highly desirable to; provide a machine which is'continuously operable to segregate slabs into componentsegments of uniform size Without efl'ecting the continuity of, op re en r r qu in n m reu rep e ee of .cntters and similar mechanism employed in l eu ther e' v .ne. object of t e r e f l ye t e s" t simplify theconstruction: and improve the J eptioned.
