I WILLIAM FREDERICK NEEDHAM, of Branston Street Works, in the City
of Birmingham, Manufacturer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to improvements in wood screws by which they may be
more useful for connecting the angular part of wooden structures together, and
more particularly intended for the securing of the angular parts of bamboo
furniture together.
It consists of a screw having an eye part formed at a short distance from the
head, that is, between the head and the wormed or screwthreaded portion.
This may be done either by forging or cutting out and otherwise shaping the
entire screw from one piece of metal, or it may be formed of two parts in either of
the following or similar ways:-I take what is now well known as a screw eye, and
further provide a short screw blank having a head and a short length of shank.
The end of this shank is saddle grooved so as to fit on to the eye of the screw.
The two are now hard soldered or brazed together and in such a manner that the
nick or key formation upon the head shall bear a certain relationship of position to
the said eye; or instead of this I take the screw eye as before, but in this case the
eye is made of an oblong shape. I also take a short shanked headed pin, but
instead of grooving its end, I make the shank of sufficient length that it
may be
bent or bowed around the one end of the eye aforesaid and firmly closed down
thereon so as to practically make the two into one piece.
Its use is effected as follows:-When it is desired to connect to an upright
piece for instance, two other horizontal pieces or bars which latter are at right
angles to and in the same plane as each other, I make an oblong hole in the side of
the upright piece through which the eye of the said screw may be passed. The
horizontal pieces are shaped to fit against the said upright, and their ends also
plugged in the ordinary manner. The improved screw pin is now passed through
the holes in the upright into the horizontal bar and screwed home by which the
said horizontal bar is secured to the upright. In screwing this up however the eye
(which is now inside of and central with the upright piece) is so left, that an
ordinary screw passing through the said upright at right angles thereto will pass
through the said eye and thence into the other horizontal bar by which the latter
may be firmly secured. The exact position of the eye of the improved screw is
determined by providing that the nick or key formation by which the screw is
turned, shall have a certain relative position thereto; so that by seeing where that
is, the position of the eye (inside) is also known.
By this means the horizontal bars of bamboo and other similar structures may
be much more readily and securely fastened together than by the various means
now in use.

page_text: I WILLIAM FREDERICK NEEDHAM, of Branston Street Works, in the City
of Birmingham, Manufacturer 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 :-
This invention relates to improvements in wood screws by which they may be
more useful for connecting the angular portions of wooden structures together, and
more particularly intended for the securing of the angular parts of bamboo
furniture.
'It consists of a screw having an eye part formed at a short distance from the
head, that is, between the head and the wormed or screwthreaded portion,―
through which a transverse screw may pass in the same plane.
In order to more particularly describe and explain this my invention, I have
appended hereunto an illustrative sheet of drawings, upon which are figures and
numbers of reference.
Figs. 1 to 9 inclusive are views of the screw as it may be variously made.
Fig. 10, is a sectional plan view showing its application.
Fig. 11, is a vertical sectional view on line AB showing more particularly the
screw constituting my invention.
This my improved screw is preferably made, either by forging or cutting out
and otherwise shaping the entire screw, from one piece of metal, as shown in
Figs. 4 & 5.
The form here shown (Figs. 4, 5, 10 & 11) I find to answer best. I provide
that the barrel (or plain part) 12, of the screw shall be made so much longer than
is usual, and then submit such part to press tools, by which the detour or bend 13,
is made, thereby forming the eye opening 14. The head 15, having the screw-
driver nick 16, (or other rotating means) and the screwthread 17, are of ordinary
make. It is important however in this and the subsequent illustrations that the
nick 16 or its equivalent should bear a known relationship of position to the eyc 14,
so that when the latter is hidden within the structure, its position may be known
by the direction of the former. In some cases I may make the eye, having a
complete circle as seen at 14", in Fig. 6, where it is cut, stamped or forged in one
piece and then screwed or otherwise finished as may be required.
eye
In some cases I may form such a screw of two parts as follows:-I take what is
now well known as a screw eye 18, see Figs. 1, & 3, and further provide a short
screw blank 19, having a head 20, and a short length of shauk. The end of this
shank is saddle grooved at 21, so as to fit on to the circumference of the of the
screw. The two are now hard soldered or brazed together as seen in Fig. 3, or,
instead of this I take the screw eye as before, but in this case as shown in Figs. 8
& 9, the eye 18, is made of an oblong shape. I also take a short shanked headed
pin 19, but instead of grooving its end, I make the shank 20%, of sufficient length
that it may be bent or bowed around the one end of the eye aforesaid and firmly
closed down thereon, as shown in Fig. 9, so as to practically make the two into one
piece.
Its use is effected as follows, and as illustrated in Figs. 10 & 11. When it is
desired to connect to an upright piece 22, for instance, two other horizontal pieces
or bars 23 & 24, which latter are at right angles to and in the same plane as each
other, I make an oblong hole in the side of the upright piece 22, through which
the eye 14, of the said screw may be passed. The horizontal pieces 23 & 24, are
shaped to fit against the said upright, and their ends also plugged in the ordinary
manner. The improved screw pin is now passed through the holes in the upright
into the horizontal bar 24, and screwed home by which the said horizontal bar is

page_text: secured to the upright. In screwing this up however the eye 14, (which is now
inside of and central with the upright piece) is so left, that an ordinary screw 25,
passing through the said eye and thence into the other horizontal bar 23, by which
the latter may be firmly secured.
By this means the horizontal bars of bamboo and other similar structures may
be much more readily and securely fastened together than by the various means
now in use.
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 [
claim is :-
The improved screw as herein described & illustrated, having the eye or
opening 14 or 14*, as set forth and for the purposes specified.
