PROVISIONAL SPECIFICATION.
Improvements in Wire Brushes.
I THEODOR DIETSCHY of 9 Brunngasse, Zurich, Switzerland, Manufacturer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to a wire brush adapted for use in a dry condition, for
all cleaning, scraping or scrubbing purposes, and more especially for the cleaning
of floors, as a substitute for the steel filings hitherto frequently employed.
The invention may be carried out in various forms, for example as a hand brush,
a broom (with a handle or stick), a "block" brush, or a rotary brush.
The improved wire brush differs from similar brushes. previously known in this
particular, that the wire, instead of being arranged in bundles, is set somewhat
like the teeth of a card; the pieces of wire being moreover Ushaped and, if
preferred, slightly bent in the form of knees, the brush surface thereby acquiring a
smooth and even, velvet like appearance.
The pieces of wire are inserted into india-rubber, leather or similar material,
and to prevent their protruding through such material, as well as their coming
out, the back of the hrush (constituted by the leather, rubber or like material) is
covered with an additional sheet of the same or similar material. To impart the
maximum elasticity to the brush, its body is, besides, lined with suitable padding,
which may consist of felt, cotton-wool or the like.
To prevent the wires situated at the edges of the brush from bending outwardly,
the brush may be surrounded with a fitting or guard extending some distance
down the wires, and secured to the body of the brush in such a manner, that it
may readily be removed and replaced by another when required.
In brushes of the "block" type constructed according to this invention I
pivotally connect the handle with a disc arranged to be free to turn in a horizontal
plane in the brush body and acting also as a weight, this arrangement permits the
brush to be operated from all sides. I also provide a suitable stop device for
preventing the handle from swinging over. Around the body of the brush I
place a removeable india-rubber ring or buffer or the like, the object of which is
to deaden the shocks sustained by the brush in accidentally striking the walls or
furniture, when in use, and thereby to protect it from injury.

Improvements in Wire Brushes.
I, THEODOR DIETSCHY, of 9 Brunngasse, Zurich, Switzerland, Manufacturer,
do hereby declare the nature of this invention and in what manner the same is to
o be performed to be particularly described and ascertained in and by the following
statement:-
This invention relates to a wire brush adapted for use in a dry condition for

of floors as a substitute for the steel filings hitherto frequently employed.

O be performed to be particularly described and ascertained in and by the following
statement:-
This invention relates to a wire brush adapted for use in a dry condition for
all cleaning, scraping or scrubbing purposes, and more especially for the cleaning
of floors as a substitute for the steel filings hitherto frequently employed.

page_text: The invention may be carried out in various forms, for example as a hand brush,
a broom (with a handle or stick) a "block" brush, or a rotary brush.
The improved wire brush differs from similar brushes previously known in this
particular, that the wire instead of being arranged in bundles is set somewhat
like the teeth of a card, the pieces of wire being if preferred slightly bent in the
form of knees, the brush surface thereby acquiring a smooth and even velvet like
appearance.
The pieces of wire are inserted into cloth india-rubber, leather or similar
material, and to prevent their protruding through such material, as well as their
coming out, the back of the brush (constituted by the leather, rubber or like
material) is covered with an additional sheet of the same or similar material. To
impart the maximum elasticity to the brush, its body is, besides, lined with suitable
padding, which may consist of felt, cotton-wool or the like.
To prevent the wires situated at the edges of the brush from bending outwardly,
the brush may be surrounded with a fitting or guard extending some distance
down the wires, and secured to the body of the brush in such a manner that it
may readily be removed and replaced by another when required.
In the accompanying drawings,
Figures 1 and 2 are respectively an elevation and a vertical section of one form
of wire brush constructed in accordance with this invention.
Figure 3 illustrates on an enlarged scale in sectional side elevation and plan
method of attaching the pieces of wire forming the "hairs" of the brush.
a is the body of the brush, 6 is the padding consisting of cotton-wool or the
like, c is a cover pasted or attached in any convenient manner to the back of the
brush support d, which cover may consist of cloth, leather india-rubber, or other
suitable material. e is the fitting or guard for preventing the wires situated at
the edge from being bent outwardly. The brush may assume any desired shape
and any suitable material may be employed in making the guard piece e.
Figure 4 is an elevation and Figure 5 a section of a "block" brush.
In Figure 4 the wires are shewn as being bent or knee shaped, and this figure
also shews in what manner the improved brush should be used for brushing or
cleaning purposes.
In Figure 5 a casting is shewn to be secured to the body a of the brush by
means of screws g which casting is intended to exercise the requisite pressure upon
the brush when the same is in use.
Brushes of the "block" type, such as have hitherto been used, were attended
with the drawback that they could be operated from one side only. To avoid this
disadvantage, in the present arrangement the casting is provided with two
discs hh revolvable in the casting in a horizontal plane and rigidly connected
with each other by a spindle k, a set screw I passing through a curved slot in the
casting (said curved slot being struck from the centre line of spindle k) enables
the discs h¹ to be drawn towards one another and thus to be clamped or adjusted
in any desired position. Owing to this arrangement the brush may be operated
from all sides.
To prevent the brush from slipping or swinging over whilst in use the handle
guide secured to or integral with the rotary disc or block h is fitted with an
additional set screw m. The part n is a sleeve for the reception of the handle or
stick and is preferably tapped with a view to the secure attachment thereof.
Around the body a of the brush I place a removeable ring or buffer o of india
rubber or other suitable material, the object of which is to deaden the shocks
sustained by the brush in accidentally striking the walls or furniture when in use,
and thereby to protect it from injury.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is :-
1. A wire brush constructed with bent wire "hairs" fitted in a support made of

page_text: cloth leather india-rubber or the like, and a cover or lining applied to the back of
said support and consisting of any suitable material such as cloth, leather, india-
rubber or the like for the purpose of preventing the wires from becoming loose
in the support or penetrating into the padding, substantially as described.
2. In a wire brush such as referred to in the preceding claim, a fitting or guard
arranged around the hairs or wires for the purpose of preventing those hairs or
wires which are situated near the edges of the brush from bending outwardly,
substantially as described.
3. A wire brush in the form of a "block" brush or broom, consisting mainly of
a disc arranged to turn in a horizontal plane in the body for the purpose of enabling
the brush to be operated from all sides, in conjunction with a stop device provided
in the handle guide whereby the brush is prevented from swinging over,
substantially as described and illustrated in Figures 4 and 5 of the annexed
drawings.
4. A wire brush such as referred to in the three preceding claims, fitted with a
pad or buffer of india-rubber or other suitable material placed around its body to
protect the same from injury when in use, substantially as described and illustrated
in the annexed drawings.
