Fig. 2 is a small plate or heading, tobcused on the centrea post A in lieu of the table D, when sawing falling-moulds.
What I claim as my invention, and desire to secure by Letters Patent, is-,
The inclined and adjustable revolving platform or table/D, constructed to operate substantially as described, and for the purpose set forth. i
I also claim, in combination with the post A, the plate or heading I, constructed .to operate substantially es and for the purpose set forth.
