IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR SECURING HANDLES TO THE HEADS OF BRUSHES, BROOMS AND SIMILAR OBJECTS
Year: 1884

page_text: I, JOHN WILLIAM KENYON of Great Western Street Manchester in the County
of Lancaster Mechanical Engineer do hereby declare the nature of my invention
for IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR SECURING HANDLES
TO THE HEADS OF BRUSHES, BROOMS AND SIMILAR OBJECTS to be as follows:-
.These Improvements relate to, the means adopted for securing handles to the
heads of brooms, brushes and other similar objects and consist .in attaching to
the end of the handle an expansible screwed ferrule which is opened or expanded
by an internal cone when the handle fitted therewith is screwed forced or driven
into its socket. By this means the screwed portion of the ferrule is bedded and
forms a corresponding thread in the socket .and the handle may be unscrewed
and removed therefrom-and replaced therein at will.
In carrying out my Invention I attach to that portion of the handle which
would otherwise be placed in the socket a short metallic tube or ferrule the upper
portion of which encloses the end of the handle. The lower portion which enters
the socket is shaped to the frustrum of a cone and is screwed externally with. a
coarse pitched screw the thread of which is formed to cut into the socket and
produce a corresponding thread therein. The cylindrical or upper portion of the
ferrule has cut or otherwise formed in it one or more narrow longitudinal slots or
saw kerfs and a hole for the passage of the nail or screw by which it is secured to,
the handle. The lower or conical portion has also formed in it one two or more
similar longitudinal slots. The interior of this lower portion is formed with a
taper hole and is fitted with a conical plug in such a manner that when the handle
is driven or forced into the socket the conical plug will be forced into the taper
hole of the ferrule which will then be expanded and the screw thereon be bedded
into the socket.

page_text: I, JOHN WILLIAM KENYON of Great Western Street Manchester in the County
of Lancaster Mechanical Engineer do hereby declare the nature of my invention
for IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR SECURING HANDLES
TO THE HEADS OF BRUSHES BROOMS AND SIMILAR OBJECTS and in what, manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:
These Improvements relate to the means adopted for securing handles to the
heads of brooms brushes and other similar objects and consist in attaching to
the end of the handle an expansible screwed ferrule which is opened or expanded
by an internal cone when the handle fitted there with is screwed forced or driven
into its socket: By this means the screwed portion of the ferrule is bedded and
forms a corresponding thread in the socket and the handle may be unscrewed and
removed therefrom and replaced therein at will.
In order that my Invention may be more readily understood and carried into
practical effect I have hereunto appended a sheet of drawings marked with letters
of reference, similar letters denoting similar parts on the various figures.
Fig 1 represents a longitudinal section of the apparatus Fig 2 a side view and
Figs 3 and 4 show modified details of construction.
•
To that part of the handle which would otherwise be placed in the socket a
short metallic tube or ferrule A. C is attached, the upper end of which encloses the
end of the handle B. The lower portion of the ferrule which enters the socket is
shaped to the frustrum of a cone as shown at C Fig 2. The conical part of the '
ferrule is threaded externally with a coarse pitched screw the thread of which is
formed to cut into the wood of the socket into which it is fitted. The cylindrical
upper portion A of the ferrule has cut or otherwise formed in it one or more saw
kerfs or narrow slots D and a hole E for the passage of the nail or screw by which
it is secured to the handle. The slots or saw kerfs D permit some degree of
expansion to the ferrule and allow it to fit handles varying in size within moderate
limits.
The lower conical part C of the ferrule has also formed in it one or more narrow
slots or saw kerfs D¹. The most convenient number of slots D' is three. These
enable the part C to expand.
The interior of the lower part C of the ferrule is formed or provided with a
taper hole the larger diameter of which is at the bottom of the ferrule and it may
be fitted with a taper or conical plug F which projects beyond the end of the
ferrule. When the handle with the ferrule attached thereto is driven forced or
screwed into the socket, the projecting end of the conical plug F coming in contact
with the bottom of the socket the plug will be forced into the ferrule the lower
portion of which will thereupon expand and the screw be imbedded in the socket.
Instead of the.conical plug F any equivalent therefor may be employed such for
example as a ball of metal or other hard material F¹ as shown in Fig 4.
The arrangement of the conical plug and taper recess shown in Figs 1 and 2
may be reversed That is to say the taper hole in the lower part of the ferrule may
have its smaller diameter at the top in which case the conical plug K or its
equivalent is inserted from the top of the ferrule and is forced forward by the
handle thus expanding the lower part of the ferrule as already described. The
upper part of the ferrule may have an internal screw formed therein into which
the handle may be screwed.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is:
The method of and apparatus for securing handles to the heads of brushes
brooms and similar objects, the apparatus consisting essentially of the ferrule A. C
and the plug F, or its equivalent substantially as hereinbefore set forth and
described with reference to the appended drawings.
