Improvements in Apparatus for Containing and Applying Paint,
Adhesive Liquids, and the like.
I, NEWNHAM BROWNE, of 73, Cheapside, in the City of London, Fellow of the
institute of Patent Agents, do hereby declare the nature of this invention for
IMPROVEMENTS IN APPARATUS FOR CONTAINING AND APPLYING PAINT, ADHESIVE
LIQUIDS, AND THE LIKE" which invention has been communicated to me from
abroad by Teodor Remus, of Dresden, in the Empire of Germany, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The usual method of applying paint and adhesive liquids etc. is attended with well
known disadvantages, the excess of liquid taken up with the brush and scraped off
against the side of the pot gets transferred to the brush handle and thence to the
hands of the operator, the paint or paste is laid on too thickly in one place and too
thinly in another so that the paint etc. either dries in or thickens and so on.
The removal of these disadvantages forms the object of the present invention as
hereinafter described and illustrated in the accompanying drawings being performed
as follows:
a is a receptacle containing the liquid being closed by a tight fitting cover and, for
reasons which are hereinafter given, of not too large a section.
At the lower end of this receptacle there is an obtuse hollow cone a¹ having a
rectangular opening. in its lower part. In this opening there is placed from the
inside a roller b so arranged that about one third of its circumference projects from
the obtuse cone a¹. A pin c passed through the obtuse cone a¹ serves as axis of
rotation to the roller b. The flat ends of the said roller 6 fit so closely to the adjacent
edges of the opening as is necessary to prevent the liquid from escaping, but at the
same time to permit the roller to rotate freely on its axis. Between the circum-
ference of the roller band the corresponding sides of the opening in the obtuse cone a¹
sufficient space is left to allow of the passage of a thin filin of the liquid adhering to
the said circumference.
Fig. 3 represents as an additional part of this arrangement being a foot, or stand, d
formed with a hollow in its upper part d' fitting the obtuse cone a' so as to closely
embrace the latter.
When not in use the receptacle a is placed on the stand d with its obtuse cone a¹
inserted in the hollow cone as represented in Fig. 4. In consequence of the close
fit between the parts a¹ and ¹ and owing to the small air space that is left inside the
stand, evaporation of the water, varnish, or other solvent employed in the liquid and
consequent drying-up of the latter is prevented and its fluidity is uniformly
maintained.
When in use the receptacle which as already stated is not to be made inconveniently
large for this purpose is grasped somewhat after the fashion of a paint brush and the
roller is moved over the surface to be coated. In consequence of the rotary motion,
thus induced, the roller b deposits upon this surface a thin layer or coating of the
liquid taken from the receptacle d.
To obtain a thicker coating the roller & must be passed several times over the same
place.
When it is required to make a stripe, or band, that is wider than the roller b,
several stripes, or hands, may be formed side by side, and, on the other hand, when
the band is to be narrower than the roller & the latter is brought into contact with
the surface only with a corresponding portion of its width.
By these means it is rendered possible by the aid of this arrangement without
manual skill or dexterity to lay on paint, paste and the like in exactly the right
quantities and over the proper area according to the object in view.

page_text: A further advantage of this arrangement is that it enables adhesive liquids which
require to set and dry quickly to be applied in a thicker condition than is possible
with the employment of a brush.
The apparatus when constructed of larger dimensions, or somewhat as illustrated in
Figs. 5 and 6 is suitable for laying on paint or adhesive matter in wide bands: In
this arrangement the roller & form a cylinder and the obtuse cone a¹ is replaced by a
hollow casing a', as shown in Fig. 5 the form of the stand being likewise modified
to fit the latter.
By making the roller or cylinder b. and parts connected therewith, of suitable
width, the apparatus may be employed for applying paints, or in machines for
coating fabrics (cachirmaschinen). The fabric S to which the colouring matter or
adhesive liquid is to be applied is drawn under the surface of the roller bas in Fig. 7
and is thereby covered with paint or colour or adhesive liquid.
When this arrangement is employed in machinery or apparatus for applying paint
and the like it presents the valuable advantage of enabling thick or viscid liquids to
be employed. The drying consequently requires less time and the coated fabric, or
material, is less liable to distortion."
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is:
In receptacles an arrangement for preserving and applying paints adhesive liquids
and the like which is distinguished by a hollow obtuse cone or hollow casing (a)
forming the lower part of the receptacle (a) a roller or cylinder (6), introduced into
the latter from the inner side and capable of rotating on an axis (c) and the stand,
or cover (d) forming a receptacle for the obtuse cone or hollow casing (a¹).
