Improvements in Methods of Fixing and Attaching Handles or
Stales to Brushes.
ALEXANDER MARR Electrician No. 9 Chorlton Terrace Upper Brook Street
Chorlton upon Medlock Manchester do hereby declare the nature of this invention to
be as follows :-
An improved method of fixing and attaching handles or stales to brush by means
of a tube of iron or other metal threaded on inside and outside diameters about
one eighth of an inch thick, and about one inch long, so that when pressd into the
body of the brush, and the stale or handle pressd into the inside diameter of tube
it become firmly fixd without the aid of nails or screws, by which means a considerable
economy is effected. In ordinary brushes used for household or other purposes, a
hole is bored, in the body of the brush, and the wood handle or stale is driven into
the hole and a nail or screw is driven through the body of the brush and into the
handle or stale.
Now my invention consists of a tube of iron, or other suitable metal, about
one eighth of an inch thick open at both ends of a similar outside diameter, to the
hole which is bored in the body of the brush. The inside diameter of the tube is
similar to the outside diameter of the handle or stale of brush.
On the outside and inside diameter of tube which is one eighth of an inch thick or
thereabouts, I cut a screw thread of suitable pitch so that when the tube is pressed
into the hole made in the body of the brush and circular motion is given to it, it
cuts a similar and corresponding thread in the hole bored in the body of the brush
and so becomes firmly embedded in the brush. The tube may also be cast with
thread on the tube inside and outside diameters. I may also make the tube taper to
facilitate the entry of tube into the body of brush.
I now take the handle or stale and having tapered it slightly at one end I press it
into the inside diameter of tube, and giving it a circular motion and downward
pressure it cuts a thread on handle or stale similar and corresponding to the thread on
the inside diameter of tube and so becomes firmly embedded in the tube without the
aid of nails or screws.
I may also use a tube as before mentioned closed at one end with holes through
end for wood screws, in which case the inside diameter of tube only is threaded.
The length of tube is one inch or thereabouts.

Improvements in Methods of Fixing and Attaching Handles or
Stales to Brushes.
ALEXANDER MARR 6 Eldon Street Upper Brook Street Manchester Electrical
Engineer do hereby declare the nature of this invention and in what manner the same
is to be performed, to be particularly described and ascertained in and by the following
statement
My invention consists of a tube of iron or other suitable metal about one eighth
of an inch thick open at both ends of a similar outside diameter at the bottom of
the screw thread to that of the hole in the body or head of brush. The inside
diameter of tube at the bottom of the screwed thread, is similar to the outside
diameter of the handle or stale of brush. On the outside and inside diameters
of tube I form a screw thread of suitable pitch the whole length of the tube
so that when the tube is pressed into the hole in the head of brush and a circular
motion is given to it, it cuts a similar and corresponding in the hole bored in
the body of brush. I then taper the handle or stale and pressing it into the hole
in the tube, with downward pressure and circular motion it cuts a thread on handle
similar to thread in the hole in the tube.
My invention has got for its object, to improve the methods of fixing and attaching
handles or stales to brushes, whereby a considerable economy is secured or
effected.
In ordinary brushes used for household purposes, and similar ones, a hole is bored
into the body or head of the brush and the wooden handle or stale, is then driven
into the hole and a nail or screw is driven through the body of the brush into the
handle or stale. Handles or stales, have also, before the date of my invention been
removably attached to the body or heads of brushes by means of screwed ferrules,
tubes and the like, but so far as I am aware or have been able to ascertain, not in a
method or by a means substantially as hereinafter described as constituting my said
invention.
These improvements consist in screwing upon the end of the handle or stale, a short
tube of iron or other suitable metal open at one end or both and having form'd in
and upon it, a suitable screwthread or screwthreads; the screwed tube upon the end
of the handle or stale is then screwed into the hole ordinarily formed in the head or
body of brush.
I do not limit myself to the order of the operation hereinbefore described, since
the screwed tube may obviously be inserted into or fixed in the head or body of brush,
before the handle is screwed therein.
The screwed tube of iron or other suitable metal, may be about one eighth of an
inch thick open at both ends of a similar outside diameter at the bottom of the
screwed thread to that of the hole in the body or head of the brush. The inside
diameter of tube at the bottom of the screwed thread is similar to the outside diameter

page_text: of wooden handle or stale of brush. On the outside and inside of the tube I form a
screw thread of suitable pitch the whole length of the tube so that when the tube is
pressed into the hole in the head or body of the brush and a circular motion is given
to it, it cuts a similar and corresponding thread in the hole bored in the body or
head of brush, and so becomes firmly embedded therein.
I may also make the tube taper to facilitate the entry of tube into the body of
brush.
The tube may also be cast with thread on the inside and outside diameters.
I now take the stale or handle and having tapered it slightly at one end I press it
into the inside diameter of tube, and giving it a circular motion and downward
pressure it cuts a thread on the handle or stale, similar and corresponding to the
thread on the inside diameter of tube and so becomes firmly embedded in the tube
without the aid of screws or nails.
I may also use a tube as before mentioned closed at one end with holes through
the closed end for wood screws, in which case the inside only of tube is threaded.
The length of tube may conveniently be about one inch or thereabouts.
I desire it to be understood that I do not claim generally or essentially the insertion
of a screwed tube into the head of the brush and the subsequent insertion by screwing
of the handle or stale therein, or the reverse, as these operations have already been
employed. I would also explain that the articles herein called brushes are in some
parts of the country called "sweeping brooms
"brooms" only.
"
or
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare what I claim is
(1) The method of fixing and attaching handles or stales to brushes, which
consists in screwing a metallic tube internally and externally screwed over and through
the whole length of the tube, into a hole in the brush and in screwing the end of the
handle or stale into the tube, or the reverse, that is to say screwing the tube as
hereinbefore described, upon the handle or stale and then screwing the tube upon the
handle into the hole in the brush, substantially as described.
(2) The method of fixing and attaching handles or stales to brushes which consists
in fixing or securing an internally screwed tube into a hole in the body of the brush
and thereafter screwing the end of the handle or stale into the tube; substantially as
hereinbefore described.
