" clams N. EMERSON, or CHICAGO, ILLINOIS.
Y [B] it knownthat I, CHARLES N. EMMERsoN,
' a citizen of the United States,'residing at Chicago, in the count of Cookand State of Illinois, have'invente I a certam new and useful Improvement in Calciininers Knives, of which the following is a specification.
a calciminers knife of ordinary formation for. removing nailsor tacks from a plastered.
wall or from woodwork, whichpermits the user to .erform 'suchwork more readily and easily tliian would be'the case additional r nail pulling tools were used;
Afurther object of the invention is to so osition the nail pulling means that. the
road flat face ofthe knife will serve as a fulcrum whereby the danger of'scratching orsharp corners or edges are brought to bearagainst the construction and combination 'inafter described and claimed. Y, In-the drawings, Figure 1' is a plan view of 1 the knife; and Fig. 2 a cross chipped or otlieliwise marred. v The invention consists in the features of of parts heresectional view taken on line 22 of Fig, 1.
- The'knife is of the usualformation, comprising a thin" fiat blade 3, of substantially.
triangular formation, havinga'broad acting edge 4, from which the knife tapers rear.- wardly toward a handle 5 of the usual formation. Near the center ofthe blade is formed a round hole- 6, from which rearwardly ex- [tends a narrow converging slot ,7, th'eho'le dowfor tack is encountered the knife can belaid fiat against the wall, which brin s the nail or tack headthrough the hole in t and slot being of a general keyhole formation.
The knife is-intended to be used in the ordinary. way for working over a puttied win-v plastered wall, andwhen anail or e knife blade,
' after which the knife will be, moved forwardly until the nail or tack is tightlyengaged by the conver ing slot7 after which the nail can be readfi 7 ward pull on the h mile of the'knife. The;
laster whereby it might be {from the lastered surface.
and permit the same to be drawn thehandle upon the blade as a fulcrum, sub' y removed by an outp catamarans mm face of ,th'e'broad fiat blade, which restsflat a'gainstfthe wall, serves as a fulcrum for the movement of the handle, and this flat surface of "suflicientextent to prevent the knife from sinking into "the plaster of the wall, even-though soft, or from gouging the wall by bringing any sharp-corners, This invention has for its object to adapt v oints, or edges into contact therewith. In rawing nails or tacks,.the outward movement of the handle,
PatentedSept.15, 1908,
in most cases,"'need,not be sufficiently great to bring the knifeedge into directcont'act' withthe wall, so that at alltimesthe wide edge of th'e'blade will remain substantially in facial contact with the wall and thereby pre sent a s'ufliciently broadand extensive sur face to ermit the withdrawal of-the nail or tack wit out'in ury tothe plaster of the wall.
-Fur'thermore, t e construction of the knife marring-a plaster surface is avoided: This renders the tool superior,-for nail pulling purposes, to a hammer having a claw, in that no istance' from the acting edge of the blade to give a substantially direct outward pull to the-nail rather than a'- partial;lateral pull, such as is usually given by a hammer-or similar implement, and this is im orta'nt for the reason that a nail ortack w' easily chip or crack the plaster around'thenailhole unless the draw thereon be direct.
The knife is so formed that its usefulness as l a-knife is in now'iseimpaired by the presence of the nail slot,"- and, furthermore, the nail slot is so located'and arrangedas to render the implement peculiarly fitted and highly satisfactory in withdraw' g nails or tacks What regard as new'and desire tosec'ure by Letters Patent is A calciniiners knife comprising a-lEndle and a'broad'flat blade connected with the handle and forwardly extending therefrom, the bladehaving formed therein, a considerable distance from-the acting edge, a hole ta' )ered away from theedge and toward the andle, and adapted to engage a nailor tack by raising stantially as described.
