An Improved Malleable Iron Table Leaf Bracket.
1. THOMAS OSBORNE Machinist of 28 Ainslie Street Barrow in Furness Lancashire,
do hereby declare the nature of this invention to be as follows :—
This Invention is a Swing Bracket formed of two pieces of in. x in. half round
Iron. One part is formed by bending a piece of the said Iron cut to a length
of 2.1 ins. about 1 in. from the centre, untill the flat sides of both parts come together.
The longer part is then bent back again untill it stands at an angle of about 25 degrees
to the other part, except about two inches at the place were the bending first
commenced, and which is still left with the flat sides closed together.
The end of this long part is then bent again outward for about 4 in. till it stands at
an angle of 90 degrees to the short part which is left straight. A pin is then formed
on the bent end of the long part which corresponds to a hole in the end of the top, or
straight part, and which thus complete the hinge or swing part of the Bracket.
The other or base part is formed by bending a piece of said Iron of a length
about 6 ins. to a shape usually termed half I thus C. The top end of this piece
is in. longer than the bottom, one part being bent out 1 in. and the other or
top end 14 in. A hole is then formed in each end. The hole in the bottom end
corresponds to the size of the pin on the bent part of swing piece, and the hole
in the top corresponds to the size of the hole formed in the end end of the top or
straight part of the Swing. Another countersunk hole is formed in the middle of
base part for the purpose of fixing to rail of Table. This completes the base part of
Bracket.
When attaching the two parts together to form the whole Bracket the pin of the
swing part is inserted in the hole of the bottom or short end of base and in the inside.
The straight end of the swing with the hole in then comes with its flat side on the
"

page_text: outside of the long end or top end of the base part, and which has been bent with the
flat side outward. A 1 Screw is then inserted through the hole in the top end
of the base piece, and through the hole in the end of straight or top part of the
swing, and then screwed fairly secure into the under side of the part of a Table
to which a Leaf may be attached. This screw while secureing the Bracket to the
frame work &c. also forms the top pin round which the Bracket swings in opening
and closing. A smal plate or washer is placed between the top side of swing and the
timber to which it may be attached, and which is provided with a suitable stop for
the purpose of keeping the Bracket in a proper possition when open and shut.

page_text: THOMAS OSBORNE 28 Ainslie Street Barrow-in-Furness Wood Cutting Machinist, do
hereby declare the nature of this invention and in what manner the saine is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This Invention consists in the first place of a piece of halfround metal 23 ins.
long wide x thick, being first bent double near the centre, and with the flat
sides inward and in such a manner as to form a ring or eyelet at the centre or
doubled part See A Fig. 1. The ring or eyelet to be on one side so as to have one
side straight. The part on the ring side is then bent outward and at an angle of about
25 degrees excepting a small part of about 2 in. which is pressed close together,
forming a neck between the ring and the commencing of the angle. See B Fig. 1.
The end of the same part is again bent outward nearly at right angles with the top
or straight part. A pin is then formed on the end of this part so as to be nearly
parrallel with a hole formed in and near the end of the top or straight part.
The above forms the swing part of the Bracket. The other part or base of the
Bracket to which the part described as above is attached, is formed of a piece of
flat metal of a size to correspond with the other, and 6 in. long, and haveing each
end bent at right angles, in this manner [one end being bent 14 in. long and
the other or bottom end 14 in. long. A hole is then formed in each end. The
hole in the short end corresponds to and is made to receive the pin end of the
swing part as above described. The hole in the top or longer end is made to
correspond to and to be in a line with the hole in the end of the straight or top part
of the swing, when both parts are in a proper possition. A hole is formed in the
centre of the base part to receive the screw necessary to attach the Bracket to the
wood work or rail of Table. "See C, Fig. 1.".
•
A stop plate or washer is provided of sheet metal 1 in. long x 1 wide, and of a
suitable thickness, to be placed between the woodwork and the swing part of the
Bracket. This plate is split in the centre at one end for the space of in. Each part
so seperated is then bent at right angles and in contrary directions. "See D, Fig. 1."
A hole is then formed in the centre of one of the sides so seperated, to correspond
with the hole in the top or straight part of the swing portion of the Bracket as
described. The stop plates are also made in pairs, right and left hand, which is
effected in the bending of the split part and in reversing the possition of the hole in
same. "See E. Fig. 2 & 3.
In attaching the Bracket to the woodwork or Table rail, the stop plate is first sunk
into the wood slightly above level. A small slit is made in the wood to assist the
bent part of the plate being driven into the wood, and for the purpose of pre-
venting the plate from moveing when the Bracket is opened and closed. The pin
on the angle end of the swing part is then inserted in the hole in the short or

page_text: bottom end of the base part, when the top part of the swing with the hole will
come in a line with the hole in the long or top end of the base part, and on the
outside of the angle. A suitable screw is then passed through the hole in the top
angle of base, and also the hole in the end of the swing part, and screwed firm
into the timber through the hole in the stop plate, see F Fig. 1 thereby binding the
whole of the parts firmly together. Another screw is then inserted through the hole
in the centre of the base part, into woodwork or Table rail, when the Bracket is
securly and properly attached.
The screw that passes through the top end of the base part, and the stop plate,
being in a vertical possition, it answers the purpose of a pin or hinge, by which
the end of the swing part is secured while opening and closeing. The bent part
of the stop plate which points downward is so arranged to come in contact with
the end of the swing part, and prevents it from opening any further than at right
with the woodwork or Table rail. "See H Fig. 1.
Haveing 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,-
(1) Simplicity of Construction, Lightness of Material, combined with Strength and
rigidity when open and in its proper possition.
(2) In being attached to two seperate parts of the woodwork, the shrinking and
expanding of the Timber has no effect on the possition of the Bracket, which always
remains paralel to the top portion of the framework to which it is firmly attached by
the vertical screw.
(3) That in case of exceptional shrinkage of the Timber the Bracket should appear
to move too loosley in opening and closeing, half a turn of the vertical screw in the
woodwork will quickly produce all the steadiness necessary.
(4) That the framework to which it is attached is strengthed and rendered more
secure by the angle form of the base acting as a knee or angle block, and by the two
screws being inserted in contrary directions.
(5) The swing part being of halfround metal, with the round part outside, it allows
of being secured more firmly at the hinge with less friction, and also assists the
Bracket in closeing under the framework with more freedom than could otherwise be
the case.
(6) That a greater weight can be sustained with less perceptible shrinkage on this
principle with 2 screws fixed in contrary directions, than with 4 screws all being
inserted in one direction.
The features of novelty and originality claimed are the method of attachment of
the Bracket to two sepreate parts of the woodwork, with two screws only, combined
with the peculiar form of the stop plate or washer which prevents the Bracket from
opening any further than at right angles with the wood work. Also the utillisation of
the vertical screw as a pin or hinge round which the Bracket opens and closes.*
