COMPLETE SPECIFICATION.
Improvements in or connected with Type-writing Machines.
We, MELVIN SWARTOUT, Stenographer, residing at 85 Macdonell Avenue and
GEORGE BENGOUGH, Merchant, residing at 65 Bleeker Street, both in the City of
Toronto in the County of York in the Province of Ontario, Canada, do hereby
declare the nature of the invention for IMPROVEMENTS IN OR CONNECTED WITH
TYPE-WRITING MACHINES, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The object of this invention is to devise an automatic type-cleaning brush, suit-
able for any form of type-writing machine having a type-well or basket, which may
be cheaply manufactured, and which will owing to its simplicity, be impossible to
get out of order, and it consists essentially of suitably attaching to a convenient
part of the frame of the type-writer, a cross-bar which supports an upright or
standard carrying a type-cleaning brush located centrally in the basket and above
the level of the type when at rest.
Fig. 1 is a vertical cross section of as much of a common form of type-writing
machine as is necessary to illustrate our means of supporting the type cleaning brush
and attaching the same to the machine.
Fig. 2 is a plan view of the same.
Fig. 3 is a perspective view of our device.
Like letters of reference refer to like parts throughout the Specification and
drawings.
A, refers to the frame of the machine, B, to the cross bar supporting the
standard C, carrying the type cleaning brush D; E, refers to the type; F, to the
type-bar; G, to the connecting wires, K, the key levers, and H, the base of
the machine.
It will be noticed by reference to Fig. 1 that the cross-bar, B, is connected to
the base of the machine by a U-shaped clamp, L, having outwardly projecting
feet, a, fitting under the flange, h, of the base, H. This clamp, L, it will be noticed
is fitted with a set screw, c, for the purpose of holding the cross-bar, B, tightly
against the base, H, or other part of the machine. This cross-bar, B, passes between
the connecting wires, G, and is so arranged as not to interfere with the freedom of
their movements when in action. At or near the centre of the cross-bar, B, is a
tapped hole through which passes a threaded standard. C, carrying a type cleaning
brush, D, the object of employing a threaded standard and tapped hole is to adjust
the brush to any desired height.
The brush, D, is usually adjusted so as to permit the bristles to lie in a plane
slightly above the level of the characters on the type bars when in their lowest
position.
The brush, D, it might be stated is loosely journaled on the standard, C, so
that when struck by the type in their movements, it will freely revolve upon the said
standard.
In constructing our device, it was our object to make an automatic type cleaning
brush which could be attached to any form of typewriting machine having a type-
well.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
1st. In a typewriting machine the combination with a vertically adjustable

page_text: rotatable by the action of the type bars during the operation of writing, substantially
as set forth.
2nd. In a typewriting machine the combination of a cross-bar, B, a standard, C,
type-cleaning brush, D, and U-shaped clamp, L, having outwardly projecting feet, a,
and set-screw, c, substantially as and for the purpose set forth.
