I, HENRY WALLACE DOVETON DUNLOP, of Viewmount, Lucan, County Dublin,
Ireland, Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
--
A means of clearing the mud off materials which are too much covered and
caked with it to be cleaned by a simple brush.
To effect this I make a slit in the back of the brush at one or both ends. In this
I insert a scraper which by means of a spring on the back of the brush is kept
within the bristles but which, on being pressed down by the forefinger, protrudes
slightly through the bristles and scrapes the caked mud off-the remaining
portions of mud being easily removed by the brush in the ordinary way as the
scraper, on removal of the pressure, sinks back among the bristles.

I, HENRY WALLACE DOVETON DUNLOP, of Viewmount, Lucan, County of Dublin,
in Ireland, Civil Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My invention relates to an improvement in brushes. The object of the inven-
tion is to provide a means of clearing the mud off clothes, boots, horses legs or any
surface which is too much covered and caked with it to be cleaned by an ordinary
brush. In order that my said invention may be clearly understood, I will now
proceed to describe one way of carrying out the same with reference to the accom-
panying drawings wherein Fig. I is a side elevation of a brush fitted with my
invention and Fig. II is a plan of the same and like reference letters indicate cor-
responding parts throughout the drawings.
To effect my purpose, I make a slit s in the back B of the brush at one or at both
ends of same. At each end of this slit I place vertical guides G and between these
guides and down into the bristles or hair B₁ of the brush I insert a scraper S¹ of
hard wood or other suitable material, smooth or slightly toothed at the lower edge.
This scraper is attached at E by a moveable joint or eyes to a spring S lying
along the back of the brush or being part of the said back or of the veneer or to
a spiral or other suitable spring-arrangement by means of which, when not in use,
the scraper
is kept within the bristles.

page_text: When, however, it is desired to use the scraper, the spring S is pressed by the
finger F and the scraper is protruded through the bristles and scrapes off the caked
mud-the finger is then withdrawn and the spring brings back the scraper again
into the bristles and the remaining mud is easily removed by the latter in the
ordinary way.
Instead of making the scraper come down through the bristles, I may make it
appear at the front end or side of the back of the brush and I may modify the
action and position of the spring or other details accordingly.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what
I claim is:
A brush in which, by pressure on a spring suitably placed and acting on a
scraper, the said scraper can be made to temporarily project and to remove caked
mud or dirt and to sink back when the spring is not pressed, and thus to make it
possible for an ordinary brush, fitted with my invention, to remove dirt or mud
which is heavily caked on the surface to be cleaned.
