AN IMPROVED MACHINE OR APPARATUS FOR PAINTING WALL OR OTHER SURFACES, AND EITHER OUTSIDE OR INSIDE BUILDINGS, OR IN OTHER PLACES
Year: 1884

page_text: I HENRY BRITTEN of Sheffield in the County of York Draper do hereby declare
the nature of the said invention for "AN IMPROVED MACHINE OR APPARATUS FOR
PAINTING WALL OR OTHER SURFACES, AND EITHER OUTSIDE OR INSIDE BUILDINGS,
OR IN OTHER PLACES" to be as follows:-
This Invention relates to the construction of a new kind of mechanical painting
apparatus, to be used in painting wall or other surfaces, and either outside or
inside buildings, or in other places.
The painting machine or apparatus is made with a circular brush which is
contained in a suitable framework, the brush being supported in bearings at each
end, and it is made to be removable therefrom when required to be changed for
another brush. The brush has a cog wheel on its axle which is geared into a
larger cog wheel above on the axle of a small drum.
This drum has a spring inside which at one end is fixed to the frame of the
machine and to the drum at the other end.-On the outside of the drum is wound
a cord band or chain the loose end of which is attached to a ladder or other
support above the worker or painter, so that in drawing the machine down, the
cord band or chain in unwinding causes the mechanism to actuate and revolve the
brush, which should be held gently touching the wall or other surface being
painted.
When the cord band or chain is unwound the machine can be lifted back to the
starting point and drawn down again parallel to the previous work done.
When lifting the machine up, the drum winds up the cord band or chain,
revolving the brush backwards or not as desired, a ratchet and pawl being fixed on
one end of the drum for controlling its action.
The paint is contained in a pot can or bucket and is held in the machine under
the brush, having a revolving feeder arranged therein, which is worked by the
friction of the brush or by wheels arranged to gear with the other revolving parts
of the machine. The feeder is so arranged as to be thrown out of gear at desire,
which is effected by the hand holding the machine or by tilting it out of the
perpendicular.

I HENRY BRITTEN of Sheffield in the County of York Draper do hereby declare
the nature of my said invention for AN IMPROVED MACHINE OR APPARATUS FOR
PAINTING WALL OR OTHER SURFACES AND EITHER OUTSIDE OR INSIDE BUILDINGS
OR IN OTHER PLACES" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement in writing
and on reference being had to the accompanying sheet of drawings:-
This Invention relates to the construction of a new and efficient kind of
mechanical painting apparatus to be used in painting wall or other surfaces, and
either the outsides or insides of buildings, or in other places where painting is
required; important features of the invention being the portability of the
apparatus, its simplicity, and its automatic action when suspended.
In order that the practical carrying out of my said invention may be fully
understood, I have illustrated it on the accompanying sheet of explanatory
'drawings on which Figure 1, shows a side elevation of the apparatus, and Figure 2,
an end elevation. Figure 3, is a sectional view of the drum and its attachments.―
Figure 4, represents the spring of the drum, and Figure 5, shows the ratchet and
'pawl.
The same letters of reference indicate like parts in all the Figures of the
drawings.
This improved painting machine or apparatus is made with a rotatory brush a,
which is contained and suspended in the framework A, made of metal or other
suitable material; and B, is the handle of the apparatus, which is attached to the
back of the framework A.
The brush a, fitted on a central axle a', is supported or mounted in bearings at
each end of it, the bearing being attached to or forming part of the framework.
The brush is made so as to be readily removable when it becomes necessary or
desirable to change it for another brush. On the axle a¹, of the brush a, a cog
wheel b, is fixed which gears into a larger cogwheel 61, above, which is fixed on
the axle of the drum c. Inside the drum is a helical or other suitable spring d,
(shown at Figure 4) one end of which is fixed to the frame of the machine and the
other end to the drum. Outside the drum c, a cord (or a band or chain) e, is wound,
the loose upper end of which is attached at a convenient height above the painter
or workman using the machine, to the ladder or scaffolding on which he is, or to
any support above him, such as to a nail or peg in the wall or in the surface he
is painting, in order that in drawing down the machine the cord e, in unwinding
will cause the mechanism to actuate and make the brush a, rotate; the machine
should be held so that the brush will touch the wall or other surface being painted.
When the cord e, is unwound either partially or almost entirely the machine is
lifted back up to the starting point and is then drawn down again parallel to the
painting work previously done. While lifting up the machine the spring drum c,

page_text: automatically winds up the cord e, and revolves the brush a, backwards or not as
desired. A ratchet f, and pawl f', (shown in Figure 5,) are fixed on one end of
the drum for controlling or regulating its action.
The paint is contained in a pot, can, bucket or holder, a convenient form of such
holder being shown at g, it is held in or suspended to the machine underneath the
brush a. The paint holder g, has a revolving endless band feeder h, arranged in it
which works over two distending rollers h³, and h³, the top one h³, being suspended
to or held in the feed roller controller h¹, and the other or loose roller h³, keeps the
feeder h, down in the paint. The feeder h, is worked by the friction of the
brush a; and h¹, represents the feed roller controller, or the working can be
effected by cog or other wheels arranged to gear with the other revolving parts of
the machine. The feeder h, is so fitted and arranged that it can be put out of gear
or its motion stopped when required, this being effected by raising the feed roller
controller by the user's thumb or finger, the hand holding the machine motionless,
or by tilting the machine out of the perpendicular.
, is an adjustable scraper or dresser for removing any surplus paint from the
brush as it revolves and before reaching the surface being painted which surplus
paint then returns to the pot or paint holder, and thereby is not wasted.
i, is a tin or other thin metallic shield fitted at the back of the painting brush a,
such shield being provided to prevent the hand and clothes of the painter or user
from being splashed or spotted by the paint while the brush is revolving; and ¹, is
a projecting lip or spout affixed to or made as part of the paint holder 9, under
the brush at the front of the paint holder,-to receive any droppings or paint from
the brush.
y, is a lip or spout at the back of the pot or paint holder for replenishing the
supply of paint or for dipping in or using a hand brush therefrom when necessary.
The paint holder or can 9, is attached to and can be detached from the bottom
parts of the framework of the machine by means of suitable movable catches or
clips fitted to the framework at j, but these catches or clips are not shown on the
drawings.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I wish it to be
understood that I do not limit myself to the precise details as herein before
described and as illustrated on the accompanying sheet of drawings because it will
be evident that modifications or variations can be made therein without departing
from the principles or main features of my invention, and in conclusion I declare
that what I claim is
The construction and general arrangement and combination of working parts
constituting a suspensible and automatically acting machine or apparatus, and its
use for painting wall or other surfaces either outside or inside buildings or in
other places; such machine or apparatus being made substantially as hereinbefore
is specified and as illustrated on the accompanying sheet of drawings.
