The u nit show n in th e illu stratio n incorporates a special floating a rb o r w hich ca rries th e circu lar saw. It is th read ed and is ad ju stab le in
stan tan eo u sly to th e pro p er te n sion in o rd er to hold th e saw rigid and y et allow the feed paw ls to move it sm oothly, tooth by tooth.
The cone arb o r is of hardened steel to prev en t w ear. A lock n u t behind
th e cone a rb o r locks it to th e tread ed sh a ft on w hich it is m ounted.
T he tran sm issio n and clutch of th e filer a re enclosed in the housing

■ S. G. Frantz Co. Inc., 161 Grand street, New York, has placed on the market a F erro F ilter w hich m ag
netically removes ferro u s particles from circulating oil system s in m a
chines and engines. I t is placed near the machine or engine in the oil pipe line and becomes p a rt of the system.
It consists essentially of a set of magnetized screens enclosed in a casing through which th e liquid flows. The screens p resent th o u sands of feet of strongly m agnetized edges to the m aterial passing through. These comb and recom b the product retaining the m agnetic particles on the screen edges until the end of the run. The filter is then demagnetized and flushed.
Features of the u nit include full flow of product, low pressu re drop, high capacity, and no m oving p arts.
It does not remove any of the oil additives. All p arts are given a high finish where needed to facili
tate cleaning.
