Marhine ! "nt they fail of their purpose, for, jas all mechanics of experience know, . a reamer will follow a hole, and can, (in no sense of the word, be depended lonon to accurately atruiirhten a hole j which has been bored out. "The action of the reamer is to take its heaviest cut where the resistance. 'due to ribbing or construction of the block, is greatest, and to crowd the 'cylinder wall at the hard spots. I Where the hard spots occur there will I be a projection into the cylinder bore, 'and where the greatest resistance to jibe cut occurs there will be a hol Ilow spot. Therefore neither pistons I... ..;.. ., i. a ,.lv fiti..,l ... .. w Boring and Uroaching. "While possibly a little better than the first method, it has the same dif ficulties and disadvantages, inasmuch as the broach will follow the bored hole. 'While to, perhaps, a. less ex-t..il- Ihun h i-nmer. still the inaecur- !acy remains. It has an added dis j advantage in that at the point where the hard spots occur a tremendous strain is put upon the cylinder wall.

On the head of the machine is a grind ing head in which there is a combina tion of two, what we will call, spindle sleeves. These sleeves are both ma chined eccentrically to each other and provided with an adjustment regulat- ing the. eccentricity of travel from nothing to a desired amount. Extend ing from the inner eccentric sleeve is a main or spindle housing, in which is mounted a shaft and bearings. To the front end of this is attached the grind ing wheel." - OBSERVER WATT AOS PAY H arvest sme WILL SOON BR HERE. WHAT ABOUT YOUR THRESHING? i i wood bros.
