Fay & Egan Company's New No. 225 Triple Drum Sander The drums are made of hydraulic steel pipe. The shell is in one piece turned inside and outside and is therefore perfectly balanced and non-breakable. The drums are not forced into position there- fore, and there is no consequent springing of the shaft. The paper is held absolutely tight on the drums by their auto- matic take-up device so that the drum is not put out of balance when it begins to take up the stretch in the paper. It is suspended entirely on the shaft and does not depend upon spring pressures exerted against the shell of the drum. The patented covering furnished with the drums is non-stretch- able, firm enough to insure perfectly sharp edges and yet allow of a velvet finish. In working quartered oak and other woods of this description having hard and soft spots, the finish will be perfectly even. On account of the quality of the manufacturer's covering (the surface being absolutely true) the sanding paper is used evenly all over. All the mechanism of the machine is exposed and easily acces- sible, saving an operator many hours a week by being able to watch and prevent cutting in the screws and nuts, thus preventing wear and insuring even pressure and good work all the time. New sand- paper can be placed on all three drums in from five to seven minutes. With the manufacturer's oscillating mechanism it is practically impossible to produce waves and planer marks. All working ad- justments are immediately in front of the operator and he does not have to leave his position to make such changes as are necessary. The four corner screws are mounted on ball bearings insuring easy movement for upper works and long life and quick adjustments. The feed and pressure rolls are all made of seamless steel tub- ing being non-breakable and take a smoother finish than cast iron thus
