I claim:
1. A scraper attachment for a ?oor brush having a
head comprising an endless, substantially tubular metal
member providing two parallel straight leg portions and
having a centrally located transverse attaching plate with
a screw extending upwardly therefrom, a handle having
attachment and is adapted to receive the screw 7.
In order to attach the improved scraper. attachment, to 2% .a ferrule with an angular end portion having an aperl

positioned upon the head of the brush, the corrugations
1S and 16 of the scraper attachment being located over
the straight leg portions 4 of the brush head and the
screw 7 being received through the aperture 18 of the
scraper attachment.

The handle isthen replaced upon the brush, the aper
prising a substantially flat metal sheet having an attach
:lng portion at one end for location between the attach
ing plate and the angular end portion of the ferrule and
having an aperture in said attaching portion, said ‘aper
ture being of just suf?cient diameter to receive the screw,
two spaced hollow corrugations formed in said metal
ture 11 on the angularterminal end 10 of the ferrule 9 30 plate on opposite sides of said aperture for location over
receiving the upper end portion of the screw 7. The
wing nut 12 is then threaded upon the screw 7, ‘attach
ing the handle to they brush and clamping, the attaching
the straight leg portions of the brush head, and a for
wardly and downwardly inclined integral scraper blade
formed on the other end of said metal plate, whereby the
portion 14 of the scraper attachment tightly between the
angular portion 10 of the handle ferrule and the attach
ing plate dot the brush head, as best shown in FIG. 3.
The corrugations i5 and 16 of the scraper attachment
are ‘thus clamped ?rmly over the straight leg portions 4
of the brush head,,holding the scraper attachment rigidly
against turning movement relative to the brush,’
In this assembled condition of the scraper attachment

site .to the handle, and, as shown in H65. 1 and 3, the
brush may be used in usual manner to sweep a floor.
The scraper blade is so located that it does not in any
manner interfere with the normal use of the brush for
sweeping.

spaced hollow corrugations formed in said metal plate on
opposite sides of said aperture for location over the
