.. FULL, a lciti- .Be it known that I, PETER t facu-,go :the United Statesyand a resident ot "Vermilion, county of Erie, `fand-.State -offollowing is a specification, the principle of the invention being herein explained and the best inode iii which I -have contemplated applying that principle, so as to .distinguish it from other inventions.

The subject of the .present application is a scraping tool designed Jfor various uses,

i but witli 'particular Areference tothe requiremust be met in such tool if itA iich is to be adapted for use in scraping the deosits from the hulls ofboats. In such tools it isessential that a very secie grip of the scrapingblade be had as the force which zomust be applied to remove the deposits from the bulls is considerable and anything but -a very secure grip will permit the scraping blade to be forced back onto the holder which will in time injure or split the handle to which the holder is attached.

To the accomplishment of these and related ends said invention Ithen4 consists of fully described and in the claims.

and the following forth in detail certain mechanism embodying the' invention, such disclosed `means constituting, however, but one of various mechanical forms in which the particularly pornted out principle of the invention may be used.

In said annexed drawing :-Il`igure 1 a perspective view of my invention; Fig. 2

. is a section on the line 2--2 in Fig. 1; Fig. 3 is a section on the line 3-3 in Fig. l;

longitudinal' section on the line Jr-4, Figs. 1 and, 3 and Fig. 5 is a perspective view of a modified type of bladeV which may be used for some purposes. U The general appearance of the invention '45 is'seen from Fig. 1, there being a suitable handle 1 to which is attached a holder 2 consisting of a flat plate provided with a'pludisposed shouldered lugs 3, there being preferably four of such lugs, as shown in Fig. l. The scraping blade 4 is loosely and removably mounted between the lugs 3 and the holder 2, and the set screw 5 Yor other means is employed for retaining uw and@ in uw. holder. The

sekSCrew 5 is disposed centrally in the hold in@ member for the vpurpose of 'giving the blade' i a Sngiiuy i lisis.

in Fig. 3 when 'the set" treiv'isgadJusted to hold -the blade iii 'tlieflli'olderf Theadvan- "tage of slightly arching the that a -vfniuch better grip is secured' pressing the blade" agtiinst `tlie'"lugs .or vagainst the holder, and this additional grip isrequiied to maintain the blade in its this sort adapted to be used on hulls. As will be seen from Fig. 4 the blade is bowed longitudinally as well as transversely by the pressure of-the set screw. Such pressure is absolutely necessary in such a' tool as mere frictioual contact betweenthe blade and the'liolder has proven to. be insufficient to maintain the blade in positioin By placing the set screw centrallyA of the lugs the blade is inade to engage against both the lugs and the holder as will'be seen from Figs. Q and 3. The blade is here shown to 'be engaged on either side .against lug and plate and this leverage engagement as it -may be termed is extremely secure. Additional security is obtained from the longitudinal deflection of the blade which gives the saine tivo point leverage engagement .in that plane. 'This engagement. is so secure that any pressure which the average workman may put upon the tool is insuflicient to Cause slippage of the blade.

The blade 6 shown in Fig. '5 will. preferably be used for horizontal surface work such as decks, etc., and will be held in enil gageinent with the holder in the same manner as is the straight blade. I have shown the blades sharpened at either end to increase the use of eachv blade `before resharpening but .this may be done as individual users desire.

present holding means adapt my scraping tool to rough work hulls of vessels andthe like to which previous scraping been totally inadequate.

Other modes of applying the of my invention may be explained instead of the one explained, changebeing4 made as regards the mechanism herein disclosed, provided the means stated by. any of the tollowing claims or the equivalent of such stated means be employed.
