PROVISIONAL SPECIFICATION.
Improvement in the Manufacture of Trivets or Supports for Fixing
against Fire Bars or Grates.
WALTER SMITH BRADLEY Galvanizer Albion Works Bilston Staffordshire
do hereby declare the nature of this invention to be as follows:-
The object of my invention, is to make what is commonly known as a trivet,
which slides backwards, & forwards, so as to regulate the amount of heat required
and also to be able to raise, and fall the same, to a desired angle, by a simple and
secure appliance.
In order to do this, I make first the trivet plate, this I bend down on the front
edge, facing the fire, preferably to an obtuse angle, so that the edge of the same,
prevents the trivet plate, coming too close to the fire bars, and the ashes falling
thereon, and I pierce cars out of this plate, and throw them up to support whatever
is placed upon the trivet. I then pierce two holes at the end of the bent down
angle afore described which act as guides, or runners, for the plate, when sliding on
the frame.
Having done this, I now construct the frame itself, after the ordinary method,
viz. a piece of rod iron, bent round with 2 straight sides, or arms, these arms being
rivetted to a cross piece, which carries the hooks, for support.
Upon these arms the trivet plate slides, & under the trivet plate itself, I place
a further loose slide, working on the same arms, & carrying a handle, which is
pivoted to it, at one end of this handle I fix one, or more levers, of different lengths
my object being that when the handle is revolved partially, either to the right or
left, these said levers, working under the plate, raise or fall it, according to their
respective lengths, and are also so constructed that when revolved past their centres,
they are stopped off, from further travel, and having once past their centres, they
will not allow the plate to fall until the action is reversed, when however these
levers are in their normal position, the plate remains flat. I also construct this
handle so that I can draw the trivet plate, backwards & forwards, as well as raise
it, & I do so, by rivetting a stay or support underneath the trivet plate and allow
it to pass through a slot, in the afore described loose sliding bar, which carries the
handle, thus connecting the two parts at the same time, & allowing the plate free
power of rising. I can therefore by this means, draw backwards, or forwards, or
raise the trivet securely by the same hand & by one operation.

Improvement in the Manufacture of Trivets or Supports for Fixing
against Fire Bars or Grates.
I WALTER SMITH BRADLEY Galvanizer of Albion Works Bilston Staffordshire
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, reference being had to the accompanying drawings and to the
letters & figures marked thereon :-
The object of my invention is to make what is commonly known as a trivet which
slides backwards and forwards so as to regulate the amount of heat required and
also to be able to raise, aud fall the same to a desired angle by a simple and secure
appliance.

page_text: In order to do this-I-make first the trivet plate, this I bend down on the front
edge facing the fire to an angle, or curved so that it prevents the trivet plate
coming too close to the fire bars and the ashes falling thereon, and I pierce ears
out of this plate and throw them up to support and prevent the slipping of what-
ever is placed upon the trivet, I then pierce two holes at the end of the bent down
portion afore described which act as guides or runners for the plate when sliding on
the frame.

Having done this I now construct the frame itself after the ordinary method
viz. a piece of rod iron bent round with two straight sides or arms these arms
being rivetted to a cross piece which carries the hooks for support.
Upon these arms the trivet plate slides, and under the trivet plate itself I place
a further loose slide or guide piece working on the same arms, and carrying a
handle which is pivotted to it, at one end of this handle I fix, one or more levers,
of different lengths my object being that when the handle is revolved partially,
either to the right or left, these said levers working under the plate, raise or fall it
according to their respective lengths, and are also so constructed that when revolved
past their centres, they are stopped off from further travel; and having once past
their centres they will not allow the plate to fall until the action is reversed, when
however these levers are in their normal position, the plate remains flat. I also
construct this handle so that I can draw the trivet plate backwards and forwards,
as well as raise it, and I do so, by rivetting a stay or support underneath the trivet
plate and allow it to pass through a slot in the afore described loose sliding guide
bar, which carries the handle, thus connecting the two parts at the same time, and

backwards or forwards or raise the trivet securely by the same hand and by one

trivet plate by the sliding tongue piece (f) which passes through the slot (9) so'
that the two plates can be caused both to slide upon the arms (a)" by means of
the handle (h) which is pivotted to the sliding piece (e) Upon this handle is
fixed ther lever (7) so formed that when turned into the position shewn in Fig. 1
the edge (m) coming in contact with the underside of the trivet plate (6) raises it
to the greatest required angle and when turned to the position shewn in Fig. 2 the
plate (b) rests upon the edge (n) of the lever (1) at a less inclination than in Fig. 1.
And when-turned into the position shewn in Fig. 3 the edge (o) is under the plate (5).

The end of that portion of the lever marked (o) is bent inwards at (p) so as to
act as a stop.

The arrangement for rising and lowering by several levers of varying lengths is
shewn in Fig. 4. The levers (m²) (n¹) & (o¹) are attached to the bar (¹) of the
handle () so that turning 'the bar (h¹) causes the levers to come successively under
the plate (b) and allow it to fall or rise as the case may be, the stop piece (p¹)

might be found-suitable for varying the angle of the trivet plate.ide so of or

page_text: Having 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 :-
1st. Constructing a trivet for hanging upon fire bars or grates, the plate of
which is capable of being slid upon the frame and at the same time, raised to
various angles by means of the combined lever tongue piece and handle as set forth
and specified.
2nd. Raising the plate of trivets by means of several levers of various lengths, or
by one lever formed so as to vary the angle of raising, substantially in the manner
herein set forth.
