An Improved Method of Fixing Joiners' Work in Houses and other
Buildings and Apparatus therefor.
I JAMES HARTLEY of 2 Wood Street, Briggate Leeds in the County of York
Broker 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:-
My invention consists in a new method of and apparatus for fixing joiners' work
in houses and other buildings, such as casements, window-frames, out-door frames,
casings for doors, architraves, chair rails, dado-framing, picture moulds, cornices,
wall brackets and the like.
My new method of fixing consists in building in the brickwork (at suitable places)
cast or wrought metal brackets, which for the sake of distinction are hereinafter
referred to as the fixed brackets; and to the wood-work I also attach cast or.
wrought metal brackets by means of screws.
These latter brackets are for the sake
of distinction hereinafter referred to as the wood-work brackets. The wood-work
brackets are arranged to fit the fixed brackets by means of a dove-tail connection,
of which two kinds are provided; according to whether the wood-work can be
moved when in position to make and unmake the connection, as for example in the
case of dado-framing and wall brackets, or whether the wood-work is immoveable
in position, as for example in the case of window and door casements.
And in order that iny invention and the manner in which the same is to be
performed may be more clearly understood, reference is given to the accompanying
drawings and to the letters and marks thereon.
Fig. 1 is a horizontal and Fig. 2 a vertical section shewing my invention as
applied to a window or door casement, in which case the wood-work is immoveable
in position; and
Figs. 3 and 4 are respectively horizontal and vertical sections shewing my inven-
tion as applied to a dado-framing, in which case the wood-work can be moved
vertically up and down in position.
Fig. 5 is a perspective view shewing the dovetail bracket-connection used in the
first case, and
Fig. 6 is a perspective view of the wood-work bracket used in the second
case.
In all the figures the same reference letter refers to the same or corresponding
part.
a is the fixed bracket, provided at the outer end with the wedge of the dove-tail
joint. The inner end is provided with two claws to secure it more firmly in and to
the brickwork. The imbedded portion is of such a thickness as to lie conveniently
in the mortar space between two adjoining bricks.
b is the wood-work bracket, which in Figs. 1 and 2 is also provided with a wedge,
whilst in Figs. 3, 4 and 6 the same is provided with a dovetail recess in which the
wedge of the bracket a fits. The woodwork bracket is fixed to the wood work by
means of countersunk screws c. c.
Both the wedges and the recesses of the dovetail connection are formed slightly
wider across the bottom or under-side than on the upper side, so that whilst the
wood-work bracket can be readily dropped over on to the wedge from the upper
side, it cannot pass down beyond, but is supported by the fixed bracket when the
woodwork bracket has been dropped down on the fixed bracket so far as to cause
the connection to be wedged tight. This description of completing connection
refers to Figs. 3 and 4.
In the case of Figs. 1 and 2 where the wood-work is immoveable in position, and

page_text: consequently also the fixed and woodwork brackets are not moveable relatively to
each other, I provide the double recessed block d, having a dovetail recess on cach
side; the recesses being wider on the under than on the upper side, so that the
block d can be dropped or driven from the upper side down over the wedges of both
the fixed and wood-work brackets (see Fig. 5), wedging or tightening the connection.
In both Figs. 2 and 4, the bricks immediately above and holding down the fixed
brackets are shewn set back, so as to give more room to drop the block d (or the
bracket ) over the wedge of the fixed bracket a. This setting back of the bricks
is not however necessary.
e is the wood-work, respectively window casement and dado-framing, Figs. 1
and 2 and Figs. 3 and 4.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is.
1° The method of fixing joiners' work in houses and other buildings by means of
fixed brackets built in the brickwork, and loose brackets screwed to the wood
work; the brick-work and woodwork brackets being connected together by dove-
tailing.
2° The construction and use of metal brackets substantially as herein set forth
and illustrated.
