Nawrocki, Civil Engineers and Patent Agents, of No. 2, Koch Strasse, Berlin, in
the German Empire. "LMPROVEMENTS IN BROOMS OR SWEEPING BRUSHES." A com-
munication by Wilhelm Richter, Engineer, of Berlin, in the German Empire.
Brooms or sweeping brushes as usually constructed have the handle fixed rigidly
to the body of the brush, so that it is often difficult for the operator to apply the
brush in corners and recesses into which the brush is prevented from entering by
the position of the handle.
Now the present Invention consists in hinging the handle to the body of the
brush by a joint which is provided with a tightening screw and nut, so that the
handle may, when required, be set in a more or less oblique attitude and retained in
that attitude by tightening the screw.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Gerard Wenzeslaus von Nawrocki in the Great Seal Patent Office on
the 3rd August 1877.

DESCRIPTION OF THE DRAWINGS.
t
Fig. 1 represents a side view, Fig. 2, an end view, and Fig. 3, a plan of a broom
or sweeping brush according to this Invention.
a is the stock or body of the brush to which is attached the bracket b forming
the one part of a hinge or joint, to the other part of which is secured the handle c.
The pin of the joint is screwed and provided with a thumb nut & by which the
joint can be tightened, as shown by the dotted lines in Fig. 1; the handle being
thus jointed to the body of the brush can be set at various angles thereto, and held
in the desired attitude by tightening the joint by means of the nut d, and thus the
broom can be applied in positions which are not readily accessible to it when the
handle is immoveably fixed to the stock.
Having thus described the nature of the said Invention as communicated to me
by my correspondent, I claim, attaching the handle to a broom or sweeping brush
by a hinge or joint provided with a pinching screw, so that the handle can be
set and held at various angles, substantially as and for the purposes herein set
forth.
In witness whereof, I, the said Gerard Wenzeslaus von Nawrocki, have here-
unto set my hand and seal; this Twentieth day of June, in the year of our
Lord One thousand eight hundred and seventy-seven.
