An Apparatus for Distributing Dry Enamel or such like Powders or
Compositions upon Steel, Iron, or other Plates, for the Purpose of
Fusing or Burning thereon.
I, WALTER BAGSHAW of 34 Tower Street, Dudley, Worcestershire, Civil and
Mechanical Engineer do hereby declare the nature of this invention to be as
follows :-
The machine or apparatus may be made of any suitable material, and is enclosed so
as to prevent the escape of the fine dust of which the powder is composed, and consists
at the top of a receiver or hopper with two or more adjustable regulators, close to
which is a plate or plates working in bearings, and moving in a horizontal direction
from side to side in the bottom of the hopper and between the adjustable regulators.
Directly under the plate or plates is placed one or more double inclined riddles or
sieves of the required mesh, attached to steel, iron or wood springs or hangers and
which work or move in a horizontal direction at right angles to the plates or slides in
receiver or hopper, and catches the powder as it falls from between the adjustable
regulators of the hopper. On each side of, and at a suitable distance from, the inclined
riddles or sieves, is placed one or more vertical spindles or shafts working in bearings
attached to the top of the machine, and upon these spindles are fixed the cranks,
eccentrics or cams to give the necessary motion to the movable plate in hopper, and also
to the inclined sieves or riddles.
At the bottom of each vertical spindle is fixed a long bush or collar, in which is
inserted a suitable number of rows of steel or other wire rods, these are placed at a
sufficient distance from each other, so as to allow the rows of wire rods fixed to the
corresponding vertical spindles, to revolve between without touching, and between each
row of revolving wire rods, and attached to the sides of the machine are other wire
rods forming a stationary grid or screen.
At a distance beneath the revolving spindles, at each end of, and throughout the
length of the machine at convenient distances from each other, and working in
bearings, are placed rollers, either of wood, iron, india rubber or other suitable
material, singly or combined, these rollers carry the plates to receive the powder,
and may be worked by means of an endless band, chain or other suitable mechanical
means.
Below the revolving rollers within the machine is fixed a collecting hopper to receive
the composition or powder not used or deposited upon the plates, and from which the
powder is conveyed by a spout or trough to the elevators which raise the powder to the
receiver or hopper at top of the machine.
At each end of the machine is a slot of sufficient width and length to allow the
plates to pass into and out of the machine, such slots being contracted or otherwise
when required.
At the end of the machine and close to the slot from which the plates are delivered,
is placed a light polished roller of suitable size, working in slot bearings, and so
arranged that the powdered plates pass underneath, the surface of the roller being kept
free from dust by means of a rapidly revolving brush or pad.
The machine or apparatus may be made as a fixture as herein described, or, it may
be made to travel upon rollers or slides, the plates to be powdered in this case remaining
stationary, the whole apparatus being worked by steam, hand or other power the.
necessary parts being connected by means of bands, pulleys or the like, to give the
required speeds.

An Apparatus for Distributing Dry Enamel or such like Powders or
Compositions upon Steel, Iron, or other Plates, for the Purpose of
Fusing or Burning thereon.
1 WALTER BAGSHAW of 34 Tower Street, Dudley, Worcestershire Civil and
Mechanical Engineer, 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 :-
The machine or apparatus may be made of any suitable material and is enclosed so
as to prevent the escape of the fine dust of which the powder is composed, and consists
at the top of a receiver or hopper with two or more adjustable regulators, through
which is a plate or plates working in bearings and moving in a horizontal direction
from side to side in the bottom of the hopper and between the adjustable regulators.
Directly under the plate or plates is placed one or more double inclined riddles or sieves
of the required mesh, attached to steel, iron or wood springs or hangers and which
work or move in a horizontal direction at right angles to the plates or slides in receiver
or hopper, and catches the powder as it falls from between the adjustable regulators of
the hopper.
On each side of, and at a suitable distance from, the inclined riddles or sieves, is
placed one or more vertical spindles or shafts working in bearings attached to the top
of the machine, and upon these spindles are fixed the cranks, eccentrics or cams to give
the necessary motion to the movable plate in hopper and also to the inclined sieves or
riddles.
At the bottom of each vertical spindle is fixed a long bush or collar in which is
inserted a suitable number of rows of steel or other wire rods, these are placed at a
sufficient distance from each other, so as to allow the rows of wire rods fixed to the
corresponding vertical spindles to revolve between without touching, and between each
row of revolving wire rods and attached to the sides of the machine are other wire rods
forming a stationary grid or screen.
At a distance beneath the revolving spindles at each end of, and throughout the
length of the machine at convenient distances from each other and working in
bearings, are placed rollers, either of wood, iron india rubber or other suitable
material, singly or combined; these rollers carry the plates to receive the powder,
and may be worked by means of an endless band, chain or other suitable mechanical
means.
Below the revolving rollers within the machine is fixed a collecting hopper to receive
the composition or powder not used or deposited upon the plates, and from which the
powder is conveyed by a spout or trough to the elevators which raise the powder to the
receiver or hopper at top of the machine.
At each end of the machine is a slot of sufficient width and length to allow the plate
to pass into and out of the machine such slots being contracted or otherwise when
required.
At the end of the machine and close to the slot from which the plates are delivered
is placed a light polished roller of suitable size, working in slot bearings, and so
arranged that the powderd plates pass underneath, the surface of the roller being kept
free from dust by means of a rapidly revolving brush or pad.
The machine or apparatus may be made as a fixture as herein described or it may
be made to travel upon rollers or slides, the plates to be powderd in this case remaining
stationary, the whole apparatus being worked by steam, hand or other power, the
necessary parts being connected by means of bands, pulleys or the like to give the
required speeds.
In order that my invention may be fully understood, I now describe the accompanying
sheets of drawings, Sheet 1 being details of the hopper with moving plate and
regulators, Sheet 2 being a longitudinal sectional elevation of the complete machine,
the letters marked thereon refer to the same parts in either views.
A the hopper, B the plate moving in a horizontal direction through C the adjustable

page_text: regulators, details of which are shewn on each side and consists of the centre disc
with slot hole through which the moving plate works and the two half plates,
which, when in position form bearings in which the centre disc may partially
rotate and cause the moving plate to be adjusted to the required angle for increasing
or reducing the feed. D the bearings for the moving plate, E the double incline
riddle, F the hangers, G the vertical spindles working in bearings, H the eccentric
for working the moving plate, which is attached to a connecting rod and lever,
H the cam for giving a jerking motion to the double inclined riddle as shewn at
Fig. 4, and H the spring at each end of the riddle to keep it close up to its
work as shewn at Fig. 3. I the long bush or collar, J the rows of wire rods in
bush or collar, K the rollers to carry the plates to be powdered, and L the stationary
grids or screens.
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 plate or plates working in bearings and through the regulators and moving
in a horizontal direction from side to side in the bottom of the hopper.
2. The double inclined riddles attached to springs or hangers.
3. The revolving spindles with rows of wire rods attached thereto.
4. The rollers to carry the plates to be powdered through the machine.
5. The light polished roller and revolving brush or pad.
6. The apparatus substantially as herein set forth, and for the purpose, or purposes
hereinbefore described.
