A scraper for removing material, adhered to a surface, in strips. The scraper has a front scraping edge and at least one cutting edge at one end of the scraping edge. The cutting edge extends generally transverse to the scraping edge.

BACKGROUND OF THE INVENTION 
(1) Field of the Invention 
The present invention relates to a scraper and more particularly to a 
scraper for use to remove material, such as wallpaper or carpet, adhered 
to a wall or floor. 
(b) Brief Description of the Prior Art 
Known scrapers employed to remove material adhered to a surface have a 
front scraping edge. When removing material, sufficient force must be 
applied to not only lift free the material directly in front of the 
scraper, but also the material at both sides of the scraper. In addition, 
sufficient force must be applied to tear portions of the material to be 
removed from portions still adhered to the surface. Thus scraping with a 
known scraper can be very tiring. In addition some material, such as 
carpet, does not tear so that it must be cut in separate operations to 
remove loosened portions, or it must be slowly worked at to loosen it so 
that it can be removed in one piece. In either case, additional effort is 
required. 
SUMMARY OF THE INVENTION 
The object of the present invention is to provide a novel scraper which 
makes it easier to remove adhered material. 
In accordance with the present invention, this object is achieved with a 
scraper which is designed to focus the scraping effort only in front of 
the scraper, and not to waste any scraping effort to the sides of the 
scraper. For this purpose, the scraper according to the invention is 
provided with at least one, and preferably two cutting blades extending 
transverse to the scraper blade, one on each side of the scraper. As the 
scraper is pushed forwardly, the cutting blades cut the material into a 
strip equal in width to the width of the scraper blades. Thus, only the 
material directly in front of the scraper need be loosened making the 
scraping job much easier and quicker. 
The invention as broadly claimed hereinafter is particularly directed 
toward a scraper having a sharpened, front scraping edge and at least one 
sharpened cutting edge at one end of the scraping edge, this cutting edge 
extending generally transverse to the scraping edge. 
The invention as claimed hereinafter is more particularly directed toward a 
scraper comprising: a scraping blade having a front scraping edge; a 
handle connected to the scraping blade, said handle extending rearwardly 
of said scraping blade; at least one cutting blade having a front cutting 
edge; and means for mounting said at least one cutting blade on one side 
of the scraping blade with the cutting edge of said cutting blade 
extending generally transverse to said front scraping edge. 
According to a preferred embodiment of the invention, the scraper further 
comprises a blade mounting member supporting the rearwardly extending 
handle; and means for mounting the scraping blade onto said mounting 
member with the front scraping edge of said scraping blade projecting 
forwardly of said mounting member. 
According to another preferred embodiment of the invention, the mounting 
means are of the detachable type and comprise for each cutting blade: a 
dihedral mounting brace having one arm detachably connected to the 
scraping blade and another arm extending perpendicular to the one arm, 
said other arm being provided with a central threaded hole; a C-shaped 
mounting plate sized to fit over the other arm of the brace, said mounting 
plate having a central trough hole aligned with the threaded hole of the 
brace; and a locking screw passing through said through hole and engaging 
said threaded for tightening the mounting plate to the mounting brace with 
the cutting blade sandwiched therebetween.

DESCRIPTION OF THREE PREFERRED EMBODIMENTS 
The scraper 1 according to the first embodiment of the invention as shown 
in FIGS. 1 to 4, is intended to be used to scrape material, such as glued 
carpet 3, off a base surface 5 in strips 7. The scraper 1 comprises a 
blade mounting member 9, comprising a block of rigid material. The 
mounting member 9, as shown in FIG. 3, has a flat bottom surface 11, a 
rear surface 13, a forwardly sloping top surface 15 that terminates in a 
front edge 17, and parallel end surfaces 19 as shown in FIG. 4, that 
extend perpendicular to the other surfaces. The bottom surface 11 is 
recessed as shown at 21 to provide a forwardly sloping bottom mounting 
surface 23 and a stop surface 25 that extends at an angle with respect to 
the mounting surface 23 and to the bottom surface 11. A handle 27 is 
attached to the mounting member 9, centrally located in the rear surface 
13, and extending rearwardly of the mounting member 9. The handle 27 is 
generally aligned with the mounting surface 23. 
The scraper 1 also comprises a scraping blade 31 with a straight, sharpened 
scraping edge 33 on its front end. The blade 31 is generally rectangular 
in shape and is sized to fit in the recess 19 on the mounting member 9 
with its back edge 35 abutting the stop surface 23, and with its front, 
scraping edge 33 projecting just forwardly of the tapered front edge 17 of 
the mounting block 9. A pair of screws 39 pass through holes 40 provided 
in the mounting member 9, and through holes 41 provided in the scraping 
blade 31 to thread into a mounting plate 43. When the screws 39 are 
tightened, the mounting plate 43 firmly holds the scraping blade 31 
against the bottom mounting surface 23 of the mounting member 9. 
The scraper 1 has at least one transverse cutting blade 51. Preferably, 
however, the scraper 1 is provided with a cutting blade on each side as 
shown. Since both are identical, only one will be described in detail. The 
cutting blade 51 is generally rectangular in shape and has an angled front 
cutting edge 53. The blade 51 is adapted to be mounted against one end 
surface 19 of the mounting member 9 with its bottom edge 55 flush with the 
bottom surface 11 of the mounting member 9. The lower point 57 of the 
front cutting edge 53 is generally adjacent the end of the scraping edge 
33 of the scraping blade 31. The cutting blade 51 in its mounted position 
extends transverse to the scraping blade 31. A mounting screw 59 is passed 
through an elongated hole 61 in a mounting plate 63 and a hole 65 in the 
cutting blade 51 to screw into a threaded hole 67 in the mounting member 
9. When the screw 59 is tightened, the mounting plate 63 firmly holds the 
cutting blade 51 in position. The elongated hole 61 allows the mounting 
plate 63 to be moved relative to the blade 51 so as to locate its front 
edge 69 close to the cutting edge 53 of the blade 51 to keep the blade 51 
rigid. 
In use, the scraper 1 is pushed forwardly against a surface 5 to scrape 
material 3, that is adhered to the surface, off the surface. The scraping 
edge 33 of the scraping blade 31 scrapes the material 3 off the surface 5 
while the cutting edge 53 of the cutting blades 51 simultaneously cuts the 
material 3 into easily removable strips 7. The pushing action is exerted 
on the scraper and not on material extending past the sides of the scraper 
which would be the case if the cutting blades were omitted. 
The scraper 101 according to the second embodiment of the invention as 
shown in FIGS. 5 to 7, comprises a large scraping blade 131 provided with 
a straight, sharpened scraping edge 135 on its front end. The blade 131 is 
rearwardly extended by a handle 127 centrally attached to its rear end. 
The blade is also provided with a through hole 135 on each side, each hole 
extending at the same predetermined distances from the adjacent front edge 
133 and corresponding lateral edge 139 of the blade. 
The scraper 101 also comprises at least one, but preferably two cutting 
blades 151 extending transverse to the scraping edge 133, one on each side 
of the blade 131. Each cutting blade 151 is generally rectangular in shape 
and has an angled front cutting edge 153. Each cutting blade 151 is also 
adapted to be mounted on the scraping blade 131 in such a manner as to 
extend transverse one lateral edge 139 of said blade 131 with the bottom 
edge 155 of the cutting blade 151 flush with the top surface of the blade 
131. 
Mounting means are provided for detachably yet rigidly mounting each 
cutting blade 151 in its operative transverse position on the scraper 
blade 131. These mounting means comprise a dihedral mounting brace 171, a 
C-shaped mounting plate 173 and a locking screw 175. The dihedral brace 
171 has an elongated arm 177 provided along its length with two spaced 
apart perforations 179 and 181, and a short arm 183 provided in its middle 
with a threaded hole 185 sized to receive the screw 175. The elongated arm 
177 is long enough to reach and extend over the hole 135 of the scraping 
blade 131 when the short arm 183 extends flush with the closest lateral 
edge 139. Perforation 179 of the elongated arm 177 is left free. 
Perforation 181 which is positioned along the arm 177 in such a manner as 
to extend above the hole 135 when the short arm 182 is flush with the edge 
139 (see FIG. 6), is however closed by the stem 187 of a small screw which 
is welded therein and has a rounded head 189 of substantially the same 
diameter as the hole 135. The head 189 of the welded screw extends from 
the bottom surface of the arm 177 at a distance substantially equal to the 
thickness of the scraping blade 131. 
The short arm 183 of the brace 171 extends perpendicular to the elongated 
arm 177 and is of substantially the same height as the cutting blade 151, 
as clearly shown in FIG. 6. 
The C-shaped mounting plate 173 is adapted to fit over the short arm 183 of 
the brace 171 with the cutting blade 151 sandwiched therebetween as shown 
in FIGS. 6 and 7. The plate 173 comprises a vertical wall high enough to 
simultaneously cover the arm 183 of the brace 171 against which bears the 
cutting blade 151, and the edge 139 of the scraping blade 139 when the arm 
177 of the brace 171 is flush with the upper surface of this blade. The 
plate 173 also comprises a pair of small projecting flanges 191, 191' 
extending along its top and bottom edges respectively, and a central 
through hole 195 provided in its vertical wall so as to be in substantial 
alignment with the hole 185 of the arm 183 when the fixation device is 
set. 
Mounting of a cutting blade 151 onto the scraping blade 131 is made as 
follows. 
In a first step, the brace 171 is placed onto the scraping blade 131 and 
moved in such a manner that the head 189 of the small welded screw 
projecting from the bottom of the elongated arm 177 enters a selected hole 
135 and passes therethrough. 
Then, the blade 131 whose elongated arm 177 now extends flush with the 
upper surface of the blade 131, is orientated so that its short arm 183 is 
parallel and adjacent to the edge 139. The cutting blade 151 is placed 
against the short arm 183 and the C-shaped plate 173 is placed over them 
to sandwich the blade 151 with the hole 195 aligned with the hole 185. 
Last of all, the screw 175 is set and tightened to fix the plate 173 to 
and over the arm 183 of the brace and the adjacent edge 139 of the 
scraping blade 131. As the screw is tightened, the brace 171 starts to 
move laterally until the stem 187 comes into contact with the wall of the 
hole 135. Simultaneously, the upper and lower flanges 191, 191' move 
snuggly above and under the upper edge of the arm 183 and the lower 
surface of the edge 139 of the scraping blade 135, as clearly shown in 
FIG. 7. 
When this tightening operation is achieved, the mounting means and cutting 
blade attached thereto are rigidly set onto the scraping blade 135. Both 
the head 189 of the welded screw which is pulled under the blade 135 and 
acts as a hook and the flanges 191, 191' of the mounting plate 173 prevent 
the device and cutting blade 151 from being torn up. Both of them also 
prevent the mounting means and cutting blade 151 from moving rearwardly on 
rotating about the stem 187. 
As aforesaid, another cutting blade 151 can be mounted on the other side of 
the scraping blade 139. Of course, similar mounting means can be used to 
do so. Each cutting blade 151 may be perforated as the blade 51 of the 
first embodiment disclosed hereinabove, its perforation being sized to 
give room to the screw 175. This feature however is not compulsory if the 
blade is short enough to extend in front of the screw 175, as shown in 
FIG. 5. In such a case, the screw 175 merely acts as a stop against any 
rearward movement of the blade 151. 
The scraper 101' according to the third embodiment of the invention as 
shown in FIGS. 8 and 9 is only a variant of the scraper shown in FIGS. 5 
to 7. For this reason, the same reference numerals provided with a 
distinguishing prime (') have been used in the drawings for identifying 
the same structural elements. 
The scraper 101' differs from the scraper 101 in that its scraping blade 
131' is provided with a detachable front scraping edge 133'. The edge 133' 
extends forwards and bears against a small upwardly projecting stop bead 
201 forming an integral part of the blade 131'. The scraping edge 133' is 
held in position by means of a wedge-shaped cap 203 that can be screwed 
onto top of both of the scraping edge 133' and scraping blade 131' by 
means of a pair of bolts 205 screwable into threaded holes 207 provided in 
the blade 131', rearwardly of the stop bead 201. 
In this embodiment, one or preferably two lateral cutting blades 151' are 
provided transverse to the scraping edge 133'. Such blades 151' are 
mounted onto the scraping blade 131' with mounting means similar to the 
one previously described, i.e. means comprising a dihedral mounting brace 
171', a C-shaped mounting plate 173' and a locking screw 175'. The holes 
135' used to position these mounting means are positioned adjacent the 
holes 207, rearwardly of the stop bead 201. The perforation 179' of the 
arm 177' of each brace 171' is positioned along this arm in such a manner 
as to be coaxial with the adjacent threaded hole 207 when the cutting 
blade 151' is fixed, to let the bolt 205 free to pass and engage the hole 
207. 
Advantageously, the ends 209 of the stop-bead 201 are cut to let the 
cutting blade 151 pass over and bear on top of the lateral edge of the 
scraping edge 133', thereby pinching the same and preventing the edge 133' 
from being laterally torn up. 
In the above specification as well as in the appended claims it must of 
course be understood that instead of using a threaded hole 185 in the 
brace 171 and a through hole 195 in the plate 173, use may alternatively 
be made of a through hole in the brace 171 and a threaded hole in the 
plate 173 to receive and set the screw 175. In such a case, the screw 175 
will be inserted in the direction opposite to the one shown in the 
accompanying drawings.
