This invention relates to improvements in ice scoring machines, 'and in the form herein described is applied to a machine having lmechanism for scoring a block of ice longiof which may be easily broken oif by the retail dealer, the scoring not onlyfacilitating the division of the block into smally pieces which are uniform andv marketable, but also insuring the delivering lof an accurate amount without requiring Weighing.

The device disclosed in the present application comprisesan improvement over' the invention defined in my earlier application filed August 24,1922', SerialNumber 584,-

'the samethrough the' machine.

It sometimesh'a-ppens that in machine of this type, the blocks of ice are'not-accurately placed'on the conveyor', v. or become slightly displaced during their progress through the lmachine, so thattheylstick or are thrown out of properalinement with the saws resulting.

in inaccurate scoring and possibly in `damage to the machine. -Then too,' the blocks of -ice vary somewhat in thickness-and this increasesthe` difficulties of accurately guiding One of theimportant objects of the in which provisionfis made for receiving 'blocks of varying thickness, as well'as blocks -i'whic'h .have'been inaccurately presented to l,the machine, and for arranging 'and guiding 1'* theniin such a mannerwithv relation to the sawsk that the scoring will be effected i'iia uniform manner and without Jamming. j

source of ower and certain o eratin arts of the machine, so that in case the saws en- "counter a foreign substance, or in case any i other condition arises to"interfere withthe invention consists in the, construction, combination and arrangement' of parts which' V'portion of the machineg:
