Improvements in Brush Wipers for Use with Receptacles for Paint,
Gum, and the like.
I. HENRY HARRIS LAKE, of the Firm of 'Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 relates to a brush wiper and is illustrated in the accompanying
drawing-
Fig. 1 of the drawings is a central vertical section of a mucilage bottle showing
a brush partly. in section and partly in elevation supported by the handled cover,
and the brush-wiper mechanism shown in vertical section taken on the broken
line 1-1, in Fig. 2.
Fig. 2 is a bottom plan view of the wiper-mechanism detached.
Fig. 3 is a vertical section of the wiper-mechanism taken on the broken line 3-3,
in Fig. 2.
Fig. 4 is a side elevation of one of the wiper-plates.
Fig. 5 is a plan view of the partly. formed wiper-frame.
A represents a mucilage bottle; A' a brush, A2 a cover for the bottle and 'a
support for the brush, and A³ a handle for the cover and brush, all made in the
usual well known manner.
The brush-wiper mechanism comprises a supporting frame B which may be of
sheet-metal, cut and swaged by suitable dies to form the annular depending
peripheral flange B₁ adapted to enclose the top of the bottle and secure the frame
thereon.
The peripheral depending flange may be integral with the frame or a separate
ring soldered or otherwise secured to the frame body.
The frame-body has the general form of a disk, the middle portion being cut
away, as shown in Fig. 5 to form a rectangular opening B2 and the slits 133 and 'B
projected from the middle opening toward the peripheral edge of the disk and
terminating at points in the lines of another rectangular figure represented by the
dotted lines B and B in Fig. 5.
The lines B being approximately radial to the disk and extending to the
corners of the dotted rectangular figure.
By bending at the dotted lines B and B the four triangular portions B7 of the
disk, formed by the slits down approximately at right angles to the plane of the
disk, as shown in Figs. 1 and 3, I form the hangers for the wiper-plates C and C₁
each of which is provided at each end at or near its upper edge, with a trunnion C²
adapted to enter and have its bearing in the aperture B8 formed in the adjacent
triangular hanger B'.
The lower edges of the wiper-plates are parallel with each other and oscillatory
to and from each other.
The oscillatory movement of each wiper-plate is controlled by a spring S one
en of which is secured to the disk body or frame as by solder S' and the other
end S bears upon the wiper-plate.

page_text: The springs tend to force the lower edges of the wiper-plates into engagement
with the brush inserted between them as shown in Fig. 1.
When the brush is withdrawn, the normal position of the lower edges of the
wiper-plates is in engagement with each other, as shown in Fig. 2.
As a means of maintaining such normal position in the middle vertical plane of
the apparatus and midway of the vertical planes cutting the trunnion-bearings of
the respective wiper-plates, I bend along the dotted lines B' the rectangular shaped
parts B down to the position shown in Fig. 3, to form stops for the wiper-plates,
to limit their oscillating movements toward each other, whereby they are each
prevented from passing the middle vertical plane.
The parts Bo may also each be slightly bent along the dotted lines B6 to incline
downwardly and overhang the upper edges of the wiper-plates, whereby any
drippings from the brush, as it is withdrawn from the wiper-plates, are prevented
from coming in contact with the springs to impair their action.
The operation of the apparatus is as follows:
The brush is inserted in the bottle by pushing it down between the yielding
wiper-plates which are forced apart as shown in Fig. 1.
After the brush has filled with mucilage or other contents of the bottle, it is
withdrawn, and the wiper-plates being forced by the springs against the brush at
their lower edges, wipe off the superfluous mucilage adhering to the outer surface
of the brush, and permit it to drop back into the supply beneath.
The tension of the springs can be varied for varying uses, whereby more or less
of the fluid deposit on the brush can be removed as desired.
My improved apparatus is adapted for use with paint brushes, whitewash
brushes or other brushes supplied by dipping, and can be applied to bottles, cans,
pails or other fluid receptacles.
Having now particularly described and ascertained the nature of the 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 :-
1. In a brush-wiper, the combination with a supporting frame, and means for
sustaining the frame upon the mouth of a fluid receptacle, of a pair of movable
spring-actuated wiper-plates, and a stop for limiting the movement of the plates,
substantially as described.
2. In a brush-wiper, the combination with a supporting frame, and means for
sustaining the frame upon the mouth of a fluid receptacle, of a pair of movable
spring actuated wiper-plates, and an overhanging guard-plate above each wiper-
plate, for protecting its actuating spring, substantially as described.
3. In a brush-wiper, the combination with a pair of oscillatory, downwardly
converging spring-actuated wiper-plates, of a plate-supporting frame formed from
an integral plate of sheet-metal with depending hangers containing bearings for
the wiper-plates, and a stop for limiting the oscillating movement of the plates
toward each other, substantially as described.
