PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Attachments for Affixing
Stails or Handles to Brushes, Brooms, and other analogous
Articles.
We, WILLIAM CLODE of 248 Lodge Road, in the City of Birmingham,
Musician, and JOHN SMITH, of 47 Tenby Street North, Birmingham aforesaid,
Jeweller, do hereby declare the nature of this invention to be as follows:-
:-
Our invention relates to improvements in the manufacture of metallic attach-
ments for securing or connecting loose haudles or stails to brushes, brooms and
other analogous articles.
One part of the two-part fitting or attachment to the manufacture of which
our invention relates consists of a sheet metal inside-wormed socket, preferably
having a flange at its mouth, and adapted to pass into and be secured within a
hole or sinking formed within the stock of a broom or brush, and to be there
secured if necessary, by small screws.
The other or male part of the connection consists of an outside-wormed
metallic ferrule or shoe, preferably having a slight flange at its open end, and
with the outside-wormed body part adapted to take and screw within the inside-
wormed socket before described.
The male part or ferrule takes upon the stem of the stail or handle, and is there
secured by small screws or by indenting the metal or by other means.
In carrying out the manufacture of the socket part of our attachment, according
to one method of our invention, a blank of thin sheet metal is taken, and fashioned
into a cup figure, and by a further series of shapings, the same is formed into a hat
shape. Then, by an impressing and shaping tool, the walls of the same are
helically wormed, or have formed within the inside, a screw thread, or screw
threads.
As a further method of making, we take a blank of metal, and by spinning tools,
we raise the same into a cup figure, and the screw threads are formed upon the
interior walls by a tracing tool, which impresses the same with the figure of a
screw of any desired pitch."
As another form, we take a cup-shaped blank, either open or closed at bottom,
and we impress screw threads upon the walls, or the inside walls of the same, by a
rolling process. That is, the shell to be wormed is placed upon a chuck, and the
impressing tool is made to take a traverse for producing the wormed impressions.
As a still further form, a sheet metal cupped blank is passed or rotated through
a pair of impressing dies, which sink screw threads within the walls of the same.
I propose to make the ferrule or he part of the attachment in the same manner
as described with respect to the socket, other than that the edges of the screw
threads are made to come sharpest upon the outside, whilst the sharp edges of the
socket come preferably upon the inside.
The be and she parts of the attachment may be secured together either by a
small screw or screws passing through coincident holes in the flanged parts, or by a
spring tongue formed within the one flange snapping within a depression in the
other on the parts being fully screwed home.
Dated this 7th day of January 1895.

Improvements in the Manufacture of Attachments for Affixing
Stails or Handles to Brushes, Brooms, and other analogous
Articles.
We, WILLIAM CLODE of 248 Lodge Road, in the City of Birmingham,
Musician, and JOHN SMITH of 47 Tenby Street North, Birmingham aforesaid,
Jeweller, 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:-
Our invention relates to improvements in the manufacture of metallic attach-
ments for securing or connecting loose handles or stails to brushes, brooms and
other analogous articles, principally of the kind described in the Specification of
an application for Letters Patent made by us and dated the 28th day of November
1894 and numbered 23048.
One part of the said two-part fitting may consist of a sheet metal-inside-wormed
socket, preferably having a flange at its mouth, and adapted to pass into and be
secured within a hole or sinking formed within the stock of a broom or brush, and
to be there secured if necessary, hy small screws, or other fastenings.
Another or the male part of the connection may consist of an outside-wormed
metallic ferrule or shoe, preferably having a slight flange at its open end, and with
the outside wormed body part adapted to take and screw within the inside-wormed
socket before described.
The male part or ferrule takes upon the stem of the stail or handle, and is there
secured by small screws or by indenting the metal or by other means.
In carrying out the manufacture of the socket part of our attachment, according
to one method of our invention, a blank of thin sheet metal is taken, and fashioned
into a cup figure, and by a further series of shapings, the same is formed into a
hat shape. Then, by an impressing and shaping tool, the walls of the same are
helically wormed, or have formed within the inside, a screw thread, or screw
threads.
As a further method of making, we take a blank of metal, and by spinning tools,
we raise the same into a cup figure, and the screw threads are formed upon the
interior walls by a tracing tool, which impresses the same with the figure of a
screw of any desired pitch.
As another form, we take a cup-shaped blank, either open or closed at hottom,
and we impress screw threads upon the walls, or the inside walls of the same, by
a rolling process. That is, the shell to be wormed is placed upon a chuck, and
the impressing tool is made to take a traverse for producing the wormed
impressions.
As a still further form, a sheet metal cupped blank is passed or rotated through
a pair of impressing dies, which sink screw threads within the walls of the same.
We propose to make the ferrule or he part of the attachment in the same
manner as described with respect to the socket, other than that the edges of the screw
threads are inade to come sharpest upon the outside, whilst the sharper edges of
the socket come preferably upon the inside.
Figure 1 of the accompanying drawing represents a blank of metal from which
a ferrule is made, Figure 2 represents the blank after the first process of cupping.
Figure 3 represents the next process of cupping and drawing.
Figure 4 represents a slightly taper cupped blank, necked at its closed end to
form the lead to the tool when wormed by a rotating and traversing wormed tool.
Figure 5 represents the said formed blank, crease wormed by one of the
processes herein before described.

page_text: Figure 6 represents a finished ferrule or shoe which forms the end connection
fitting for the stail or handle part of the broom.
Figure 7 represents the blank of metal from which a crease wormed socket is
made.
Figure 8 represents the first stage of cupping. Figure 9 represents a further
stage and Figure 10 a still further stage, which gives a flanged and cupped blank,
which is then crease wormed to form the finished socket Figure 11 of which
Figure 12 is a plan.
Figure 13 represents a pair of tools which we may employ in the production of
the said crease-wormed sockets and ferrules.
a is a she tool, which is inside wormed, to the outside diameter of the shoe or
socket to be formed and is a male tool, outside wormed to the inside diameter of
the said shoe or socket.
In carrying out the manufacture of a socket by means of the pair of tools
represented, we take a flanged and cupped blank Figure 10, place the same upon
the male tool, which is held stationary, and then give an advancing and rotatory
movement into she tool, when the blank is crease wormed, as represented at c,
Figure 13.
The said tools may then rotate and retire in reverse directions, when the creased
socket represented in Figure 11 is then cleared of the tools.
Instead of making the sockets and ferrules from metal blanks they may be made
from short lengths of thin tubing such as Figure 14, which are slightly tapered by
spinning or in a die and the top edges (in the case of a ferrule) rolled over as
represented in Figure 15.
The plain ferrule or socket is subsequently crease wormed either by spinning or
rolling or by suitable tools, such as already described, or by tools such as
represented in Figure 16, in which a is a roller, turning upon a rotating spindle a',
working within a bearing, whilst b is a rotating and traversing spindle, carried by
suitable bearings 62, and with the outer end wormed to the counterpart of the worm
upon the article to be produced. e is the blank which is wormed by the roller
impinging thereon and following the worm on the end of the spindle.
Although I have described that the sockets and ferrules are used in pairs, yet
either of the same may be used alone.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
First. Making broom and like attachment sockets and ferrules from sheet metal,
substantially as described and set forth.
Secondly. Making broom and like attachment sockets and ferrules from sheet
metal by the processes described and forming the screw threads thereon by crease
worming substantially as described and set forth.
