page_text: In Figures 2 and 3 the arms are represented as extending from the stock or body b
at one side of roll C to the opposite side of said roll, their curvature being such
as to draw the block firmly against the roll and to hold it there.
In Figure 2 the arms are represented as passing directly about the roll, while in
Figure 3, they are shown bent outward to pass about the frame of the carriage B.
For other styles of machine the shape of the arms may be varied as required, these
changes being merely such as fall within the province of the ordinary mechanic,
involving no departure from the invention.
It is likewise apparent that, instead of depending upon the spring action of the arms c,
they may be clamped by set screws or equivalent devices, and that, by hinging the
arms to rod F, or hanging them concentrically with the axis of roll C, the cleaning
device may be left upon the machine and shifted to and from its operative
position..
The brush, pad or cleaner being applied to the machine, in position to be struck by
the type, as the type bars are thrown up, and the ink ribbon being moved out of
the way, the carriage is drawn back to its starting point and the finger keys or
buttons are struck one after another, each type being caused to strike. three or four
times, usually, so as to ensure the thorough cleaning of each letter.
When the cleaning is completed, the brush or pad is removed and the machine is
ready for use.
The use of this attachment obviates the necessity of tediously brushing each type
by hand, as is commonly done, and it enables the operator to clean bis type quickly,
efficiently and without soiling his hands in the operation.
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 correspondents, I declare that what I claim is :-
1. In combination with a type-writing machine, a brush or cleaning device applied
to the machine in position to be struck by the type when the type bars are
actuated.
2. In combination with the roll or platen, and with the type bars of a type-
writing machine, a brush or type cleaner applied to said machine with one face
against the roll or platen and the other face in position to be struck by the type.
3. A cleaning device substantially such as described, for type-writers, provided
with arms to clasp a portion of a type-writing machine, to secure the cleaning device
in position.
4. A cleaning device substantially such as described, provided with spring arms c,
adapted to clasp a portion or portions of a type-writing machine, and to hold the
cleaning device in the required position.
5. In combination with a type-writing machine, a cleaning device substantially such
as described, and elastic fastening arms therefor, adapted to be attached to or detached
from the machine at will.
6. In combination with a type-writing machine, a brush attached to its travelling
carriage and movable over the point at which the types strike, substantially as shown
and described.
7. In combination with a type-writer, a cleaning brush applied thereto, and
removable from the lower face of the platen or roll.
