ANDREAS PETER LUNDBERG Electrical Engineer 18 Regina Road Tollington.
Park London N. do hereby declare the nature of this invention to be as
follows:-
The apparatus consists of a number of small rollers mounted on one or more
spindles.
These spindles with the rollers are then mounted horizontally on a hand grip,
preferably made of wood.
The rollers working on their spindles can be made of any material, but are
preferably made of india rubber.

I ANDREAS PETER LUNDBERG 18, Regina Road Tollington Park, London, N.
Electrical 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 apparatus consists of a number of small rollers mounted on one or more
spindles.
These spindles with the rollers, are then mounted horizontally on a hand-grip,
preferably made of wood.
The rollers working on their spindles, can be made of any material, but are
preferably made of india rubber.
It is intended to use the appliance in connection with the ordinary fluted wash
board, on the latter, the clothes to be washed, are spread out and soaped in the
usual manner.
The mechanical knuckles is then held in the hand, by means of the hand grip
and worked (i.e. rolled) up and down the board over the clothes, the dirt being
speedily squeezed out in the process.
In carrying out my invention, the method I adopt can be easily understood by
reference to Figs. 1, 2 & 3.
Fig. 1. is the side elevation of the apparatus. (a) rollers, (b) spindles (c) supports
(d) hand-grip.
Fig. 2 is an under view.
Fig. 3. is an end view.
The apparatus consists of a number of rotating bodies, mounted on one or more
spindles, these rotating bodies with their spindles being fixed by supports, to a hand
grip preferably made of wood.
These rotating bodies as shown in Figs. 1, 2 & 3, are ball-shaped, this shape
having been proved by experience to be the best, but rollers of other shapes, could
also be used, with almost equal results.

page_text: These balls or rollers effect the same object as the knuckles of the hand in
washing clothes, and do the work with greater ease and thoroughness.
The use of mechanical knuckles is more preferable than a brush, as is sometimes
used to save the knuckles of the hand, and do, not wear out the fabrics in the
cleansing process.
The great difference between the use of mechanical knuckles and a brush, is that
the brush is very destructive, & its action quickly ruins the clothes, whereas the
mechanical knuckles simply roll over the clothes & the dirt is squeezed out by the
muscular exertion of the operator on it.
Having now particularly described & ascertained the nature of my said
invention, and in what manner the same is to be performed, 1 declare that what
I claim is
(1.) A mechanical knuckle arranged as shown in the figures, with one or more
spindles, on which revolve, ball or other shaped rollers, the balls or rollers moving
independently of each other, or together, on their spindles, the whole arrangement
being mounted on a suitable hand grip as described.
. (2.) The whole apparatus substantially as described.
Dated this 11th day of December 1894.
