PROVISIONAL SPECIFICATION.
Improvements applicable to Brushes.
I JOHN ASPDEN of 58 Watson Street Deansgate Manchester in the County of
Lancaster Builder, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the means for attaching the wooden head of a sweeping
or scrubbing brush (whether made of bristles whalebone weed or other material) to
the long handle or stale thereof.
These heads are usually fastened by forcing the tapered end of the long handle
or stale into a hole made in the back of the brush head and then fixing the same by
driving in a nail, which is an insecure mode of fastening, and liable to split the head
or the end of the handle, or stale, or both.
According to my invention, I make a screw threaded hole in the back of the
wooden head and I make a corresponding screw thread upon the end of the stale or
handle so that the latter can be readily screwed into the former and will become
firmly fixed without the use of any nail, and neither the stale nor the brush head
will be liable to become split.
I also make the screw thread considerably longer than is necessary upon the
stale or handle, so that in the event of breakage or rotting at the end of the said
stale or handle, it can be readily screwed again into the head of the brush.
Dated this 22nd day of September 1890.

COMPLETE SPECIFICATION.
Improvements applicable to Brushes.
I, JOHN ASPDEN, of 58 Watson Street, Deansgate, Manchester, in the County
of Lancaster, Joiner, 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 :-
In securing the handles of what are commonly termed "long" brushes to the
stocks or heads thereof it has hitherto been customary to nail the two together in
the socket provided for the handle in the stock or glue the same, or by a com-
bination of these two methods.
My invention is intended to obviate the necessity for the use of nails in securing
the same, and thus render the brush less unsightly than hitherto, and avoid the
liability of splitting either the handle or the stock whilst driving in the nail.
The invention consists in tapping or forming on the end of the handle a screw
thread and also tapping or forming a screw thread in place of the socket usually
provided in the stock for the handle.
I will describe my invention in connection with the sheet of drawings forming
part of this Specification, wherein,
Fig. 1 is an elevation of portion of a brush handle tapped or with screw thread
formed thereon,
Fig. 2 a longitudinal sectional elevation of a stock or brush head tapped,
or with a screw thread formed in the socket usually provided to receive the
handle, and,
Fig. 3 a sectional end elevation of the stock shewing the angle at which the

page_text: tapping or screw thread is formed therein, and the position or angle assumed by the
handle on insertion.
In these figures a is the handle of the brush, b the stock or head, c the tapping
or screw thread formed on the handle a, d the tapping or screw thread formed in
the stock b, and e the bristles forming the brush.
On the end of the handle a I tap or form a screw thread c by preference about
three inches in length, and in place of the usual socket provided for the handle in
the stock I tap the same or form therein a screw thread d by preference about
one inch in depth. The tapping or screw thread in the stock may be slightly
tapered inwards so as to add to the grip obtained by the screw.
By tapping or forming on the handle a screw thread three inches in length it
will be seen that provision is made for insertion into a fresh stock. When the
stock or brush head is worn out or it is desired to change it the stock may be sawn
or cut away from the handle. Where, however, provision is not made for reinsertion
of the handle by tapping or forming the screw thread thereon to the extent of
three inches, the tapping or screw thread may be tapered on the handle, and thus
dispense with the tapering of the tapping or screw thread in the stock; but I prefer
the tapering being done in the socket and not on the handle, so as to allow of the
handle being tapped or screw thread formed thereon of a sufficient length to
provide for reinsertion of the handle in case of the length inserted in one stock
being cut away.
By this method of securing the handle to the stock it will be obvious that the
hole usually provided for the nail through the stock will be dispensed with.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is performed, I declare that what I
claim is
The method of securing the stock or head of a brush to the handle thereof which
consists in tapping or forming upon the end of the handle a screw thread, and
tapping or forming in the stock or head a screw thread to receive the tapping or
screw thread formed on the end of the handle, substantially as herein described,
and illustrated in the drawings.

JOHN ASPDEN.
