'Heretofoie the binding; screw as 23 has been provided with either a rounded or a substantially sharp point. According to such older construction wh n the binding screvv is broughtdown'uprin theblsde by e threadingection the frictional movement of the end of tllQySCI'GW relative to the blade tends to move the blade and the lever es 520 laterally with respect to each other. That is to say, as viewed in F i, the end of the screw fnioving in the clockwise direction would tend to creep toward the lower side of the plane forcing the blade tou'erd the upper side. When theend of: thescreiv is rounded this creeping and disloceting move I ment is quite pronounced, and it results in throwingthe cutting ozthr bit out'o'ft its true position. tiuclr creeping or blade I been overcome, to e considerehle extent in instances Where the end of the screw is made sharp or conicnlly pointed; buts serious ohjectionexists in such construction in tlnitithesherp pointceuses indentetionsin the blade and when e the sharp point is very apt to lind its way into some old indentation and move the blade out of position While being-tightened.

In this connection it is also pointed out that when it screw as 23 is tightened it neturelly inclines with respect to the plane of the blade owing to the movement of the upper end of the lever-'20 in a direction away from I the end of the screw is also to creepupvvard upon the blade, springing the screw end putting its threads under undesirable dlstort o'n strains, and, where e good. grip upon the ing' below s sure oi sneh tliest-oeh sides as 1! blade is hard by the sharp point, moving the blade upward and earrying the cutting edge out of its desired position.

Another iniportzint objection to the older construction in which the end of the screw directly impinges the bledeizrises trom the fact that the holdin )1.GSSHZ'B.U"OJ!; the 1'" blade is applied at only very small point or'zirez and the holding torce is theretore necessarily limited. Furthermore there is usually. it not almost in 'zirinhl i' an ope-r shrill area of Contact, 2155 the Lu gnideway to the block 13, whereby the pres- .seren' springs the blade and.

places parts oi it under undesirable strains. From the foregoing references to the older practice it will he clear that according to snrh ii-entice the holding action nponihe iron or hit is limited in quantity and, depends to a considerable exent upon spring action developed in the screw or blade, and that the epplic-ation of force is not direct.

Finch want oi a proper holding lilan'le is important to some extent in pr:
