PROVISIONAL DE MUITIVATION,
Improvements in Means for Securing Bamboo Parts or other like
Bodies together.
I, FREDERICK WILLIAM NEEDHAM, of Branston Street Works, in the City of Bir-
mingham, Warwickshire, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in ineans for securing bamboo parts or other
like bodies together and forms to some extent an improvement upon Specification
No. 2383 of 1888, for which Letters Patent were granted to me.
It is found desirable to so construct and secure the joints of bamboo as that they
shall be stronger in connection and able to carry considerable more weight than at
present is safe and therefore I have made this my invention, which is specially applic-
able to the manufacture of ladders bedsteads or other structures where the horizontal
rails are required to carry considerable weight. I make the metallic band around the
vertical post with one or more perforations to receive the horizontal rail or rails, and
coincident with these perforations I make holes through the side of the bamboo.
now fit upon the end of the rails to be jointed a tubular metallic mount which shall
tightly pass through and fit the perforation in the vertical mount and also through
the hole in the bamboo so that the bamboo itself forms a direct support beneath the
rail. The two metallic parts are now further soldered together as before.
The mounts are secured to the bamboo by pins or other suitable device. Where
more than one rail is jointed at the same place, their interior ends are preferably
mitred together. It will be readily seen that these metallic joints may be equally
applied to other material than that of bamboo, as for instance wooden rails may be
used in combination with bamboo posts, or with wooden posts.
By these means a very strong attachment is made by which bamboo in particular
by reason of its lightness may be safely used for many purposes in which it at
present is unsafe.

0 Improvements in Means for Securing Bamboo Parts or other like
Bodies together.
I, FREDERICK WILLIAM NEEDHAM, of Branston Street Works, in the City or
Birmingham, Warwickshire, Manufacturer, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
5 described and ascertained in and by the following statement:-
This invention relates to improvements in means for securing bamboo parts or

page_text: other like bodies together, and forms to some extent an improvement upon
Specification No. 2383 of 1888, for which Letters Patent were granted to me.
It is found desirable to so construct and secure the joints of bamboo as that they
shall be stronger in their connection and able to carry considerable more weight than
at present is safe, and therefore I have made this my invention, which is specially
applicable to the manufacture of ladders, furniture, bedsteads or other structures,
where the horizontal rails are required to carry considerable weight.
In order to more clearly explain this my invention I have appended hereunto an
illustrative drawing upon which are figures and numbers of reference, in which
similar numbers refer throughout to the same thing or part. -
Fig. 1, is a part sectional elevation and Fig. 2, a sectional plan (on line A-B) of
a rail and post connected together according to this my invention.
Fig. 3, is a sectional plan view showing the arrangement of mitreing two rails into
a post.
-
Fig. 4, is a view in elevation showing two cross rails connected to a post.
Fig. 5, is a plan view in section on line C-D.
Referring to Figs. 1 & 2 :-7, is the post. 8, is the rail. 9, is a metallic band
formed from a strip and bent around the post 7, and preferably secured thereto by
having its ends soldered to each other. Other means of securing it however may be
used. In this band is made a perforation to accommodate the entrance of the rail 8.
A hole corresponding to, the said perforation is also made in the post itself. I now
fit upon the rail 8, a tubular metallic mount 10, which shall tightly pass through and
fit the perforation in the mount 9, and the hole in the post, so that the material of
the post forms a direct support beneath the rail. These metallic mounts are now
further soldered together at their junction 11, with each other, thus firmly securing
the connection. Referring to Fig. 3, it will be seen that two rails 8, 8ª, are similarly
connected to the post 7, but mitred within the same, the junction 11, being also
soldered as before described. In Figs. 4 & 5, the rail 8b, is carried straight through
the post 7, together with its mount 10, and the two cross rails 8° & 8d with their
respective mounts 10, pass also into the post, the whole being then soldered at their
junctions 11, as before described.
The mounts 9 and 10, are secured to their respective rails or posts by soldering or
by pins or other suitable device.
When desired for export or other inconvenient transit the soldering process may
be left undone until the goods otherwise prepared reach their destination.
It will be readily seen that while this my invention is particularly serviceable in
the treatment of bamboo, still it may be also serviceably applied to other material,
as for instance, wooden rails may be used in combination with bamboo posts or with
wooden posts &c.
By these means a very strong attachment is made by which bamboo in particular,
by reason of its lightness, may be safely used for many purposes in which at present
it is unsafe.
Having now particularly described and ascertained the nature of this' my said
invention, and in what manner the same is to be performed, I declare that what I
claim is
Connecting the posts and rails of bamboo and other like parts to each other in the
manner and by the means substantially as set forth and shown.
