Improvements in or relating to Brushes, Brooms, and the like.
I, SILVAIN ROCHET, of 91 Grande Rue, Besançon, (Doubs) in the Republic of
France, Brush Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to brushes, brooms and the like and comprises a jointing
device which enables the brush-head and the handle to be placed in different
relative positions; such a device is applicable with advantage to mechanical
"carpet-sweepers."
"
A hemisphere or segment of a hemispherical shell is provided with a slot, and
placed in a corresponding hollow formed in the brush-head, with which it is
maintained in close connection by means of a bolt. The stem of the bolt passes
through the slot of the hemisphere or segment into the head of the brush and is
square at one end and cylindrical at the other and has its two sides planed flat in
places so that a washer thereon may not turn when the position of the brush
handle in relation to the brush head is changed.
In order to impart elasticity to the joint between the shell or segment and the
brush head and to facilitate their respective movements a coiled spring and a
washer are placed between a nut of the bolt aforesaid and another washer placed
against the interior of the hemisphere.
A screw-thread cut on the end of the brush handle fits into a female screw cut
inside a socket formed on the hemispherical segment and constitutes the attachment
of the brush handle to the segment; this attachment is made further secure by
other means.
By taking the brush head in one hand, and the handle in the other and making
the former rotate on the bolt I can bring the brush-head at right angles across
the handle. In this case the holt occupies one end of the slot in the segment.
In another position the bolt occupies the opposite extremity of the slot and the
face of the brush becomes horizontal, while the shaft still occupies its vertical
position and now coincides axially with the bolt.
In the manner described the head and the handle of the brush may be placed at
any intermediate angle in relation to each other, either in one plane alone, or as in
a ball-and-socket joint.

Improvements in or relating to Brushes, Brooms, and the like.
1, SILVAIN ROCHET of 91 Grande Rue, Besançon (Doubs) in the Republic of
France, Brush Manufacturer, 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:—
This invention relates to brushes, brooms and the like and comprises a jointing
device which enables the brush-head and the bandle to be placed in different
Г

In the accompanying drawings
Figure 1 is an elevation of a device adapted for attachment to the broom handle
and mainly, formed as a segment of a spherical shell.
Figure 2 is an elevation of a washer hereinafter referred to.
Figures 3 and 5 are plans and
Figures 4 and 6 are corresponding central sections illustrating two different
positions of the handle and broom-head in relation to each other.
Like letters indicate like parts throughout the drawings.
A hemisphere or segment of a spherical shell a the centre of which is at b
(Figure 4) is provided with a slot a¹ a² and placed in a corresponding hollow c
formed in the brush-head d with which it is maintained in close connection by
means of a bolt e. The stem of the bolt passes through the slot of the hemisphere
or segment a into the head of the brush and is square at one end e¹ and cylindrical
at the part e and has its two sides planed flat at a³ so that a washer thereon may
not turn when the position of the brush handle y in relation to the brush head dis
changed.
In order to impart elasticity to the joint between the shell or segment a and the
brush head and to facilitate their respective movements a coiled spring and a
washer are placed between a nut e¹ of the bolt e aforesaid and another washer f
placed against the interior of the shell a.
A screw-thread cut on the end g of the brush handle fits into a female screw
cut inside a socket ; formed on the hemispherical segment and constitutes the
attachment of the brush handle g to the segment a;. this attachment can be made
further secure by other means.
By taking the brush head d in one hand, and the handle g in the other and
making the former rotate on the bolt e I can bring the brush-head at right angles
across the handle. In this case the bolt occupies one end of the slot in the segment
(see Figures 3 and 4).
In another position (see Figures 5 and 6) the bolt occupies the opposite
extremity of the slot and the face of the brush becomes horizontal, while the
shaft G still occupies its original position and now is axially in line with the
bolt e.
In the manner described the head and the handle of the brush may be placed at
any intermediate angle in relation to each other, either in one plane alone, or as in
a ball-and-socket joint.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A joint device for brushes brooms and the like comprising a slotted spherical
shell a and bolt e substantially as and for the purpose described.
2. In a joint device for brushes brooms and the like the combination with the
bolt e of a spring, washers, and. a nut, substantially as and for the purpose
described.
