Improvements in and relating to Brooms and Brushes.
I, WILHELM STERKEL, of Ravensburg, in the Kingdom of Wurttemberg,
Germany, Manufacturer do hereby declare the nature of this invention to be as
follows:-
This invention refers to brooms and brushes, in which the block is composed of
two or more parallel laths, or thin, narrow boards or slips of wood, between which
the bristles, hairs or other similar material is arranged in rows; and in which the
said laths, boards or slips are connected by nails or splints passed through the
former in the cross-direction of the same.
My invention in broom-blocks and brush-blocks of the kind stated relates to
shaping the laths, boards or slips of wood in such a manner, that grooves are
formed in the same, which are closed either at the back, (or upper surface) only of
Each of the laths is thus furnished with
the block, or at the frontal sides.
projections extending either only horizontally, i.e. in the longitudinal direction of
the laths, or in a vertical direction, the said latter projections may either be made
integrally with the laths, or separate pieces may instead thereof be put into the
frontal openings of the said grooves. In some cases, I prefer to replace the said
separately inserted pieces by external mountings or fittings secured to the frontal
sides or frontal ends of the blocks, and in other cases, I prefer to employ the said
inserted pieces together with said mountings, as will all be more fully described
hereinafter.
In order to make my invention more clear, I refer to the accompanying sheet of
drawing, in which similar letters refer to similar parts throughout the different
views, and in which:
Figure 1 is a view of a broom (the stick and its fixture being left away) made
according to my invention, and seen from one of its broad sides ;
Figure 2 is a view of the same broom, the latter being shown from one of its
small or frontal sides;
Figure 3 is a side-view of a portion of a lath as used for my improved brooms
and brushes;
Figure 4 is a frontal view of some of such laths;
Figure 5 is also a side-view of a portion of a lath, the groove or channel of the
same being furnished with bristles, and being closed at its frontal end by an integral
projection of the lath;
Figure 6 is a similar view, the groove or channel being closed by a separate
piece, and the respective frontal end of the block being furnished with a
metal-cap;
Figure 7 is another similar view, the grooves being closed by a piece of sheet
of metal;
Figure 8 is a frontal view of the form of construction, shown in Figure 7, and
Figure 9 is a modification of the form of construction shown in Fig. 7, the piece
of sheet metal being replaced by a wooden plate.
Referring to Figs. 1-4, a a' a² a³ a designate the laths, which are provided each
with either one longitudinal depression or cavity (compare the lath a in Fig. 4.
and the laths a and a in Fig. 2,) or with two depressions or cavities 61 (compare
the laths at a in Fig. 4, and the lath a² in Fig. 3). Each two neighbouring

page_text: depressions or cavities form a groove, or channel, which is closed at its top by
longitudinal projections a³, Figs. 3-7 & 9, and at its frontal ends by projections a³,
Figs. 3 & 5, all made integrally with the material of the laths proper.
Within the said grooves or channels bb', or 61 61 or 616 respectively, there are
arranged the rows of bristles or hairs c, Figs. 1, 2 & 5-9, which are held either
solely by the nails or splints d, Figs. 1 & 2, drawing the laths against one another,
or by that of any suitable glueing-or cementing-medium, as indicated by the dots in
Figures 1, 2, 5-7 & 9.
The projections as of the laths, which are made integrally with the latter, may
be replaced by separate pieces (as for instance e in Figs. 1 & 6) inserted into, and
fixed within, the ends of the grooves or channels b₁, or b¹¹ or b¹ 6 respectively.
These pieces may consist either of hard material, as for instance wood, or of soft
material, such for instance as putty or a similar stuff. Especially in this latter
case, I prefer to combine with the said pieces, outer frontal mountings or fittings,
which may be constituted either by metallic caps ƒ (Fig. 6) or by metallic plates fi
(Figs. 7 & 8) or by wooden plates f, Fig. 9. These mountings or fittings may be
employed, however, also directly for closing the grooves or channels, as is clearly
shown in Figs. 7 & 9.

COMPLETE SPECIFICATION.
Improvements in and relating to Brooms and Brushes.
I, WILHELM STERKEL, of Ravensburg, in the Kingdom of Wurttemberg,
Germany, 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 refers to brooms and brushes, in which the block is composed of
two or more parallel laths, or thin, narrow boards or slips of wood, between which
the bristles, hairs or other similar material is arranged in rows; and in which the
said laths, boards or slips are connected by nails or splints passed through the
former in the cross-direction of the same.
My invention in broom-blocks and brush-blocks of the kind stated relates to
shaping the laths, boards or slips of wood in such a manner, that there are formed
grooves by the same, which are closed either at the back (or upper surface) only of
the block, or at the frontal sides, too. Each of the laths is thus furnished with
projections extending either only horizontally, ie. in the longitudinal direction of
the laths, or in vertical direction, too; the said latter projections may either be
made integrally with the laths, or separate pieces may instead thereof be put into
the frontal openings of the said grooves. In some cases, I prefer to replace the
said separately inserted pieces by external mountings or fittings secured to the
frontal sides or frontal ends of the blocks; and in other cases, I prefer to employ
the said inserted pieces together with said mountings, as will all be more fully
described hereinafter.
In order to make my invention more clear, I refer to the drawing sent in with
Provisional application, in which similar letters refer to similar parts throughout
the different views, and in which:
Fig. 1 is a view of a broom (the stick and its fixture being left away) made
according to my invention, and seen from one of its broad sides;
Fig. 2 is a view of the same broom, the latter being shown from one of its small
or frontal sides;

page_text: Fig. 5 is a side-view of a portion of aften, as for my improved
brushes;
Fig. 4 is a frontal view of some of such laths;
Fig. 5 is also a side-view of a portion of a lath, the groove or channel of the
same being furnished with bristles, and being closed at its frontal end by an integral
projection of the lath;
Fig. 6 is a similar view, the groove or channel being closed by a separate
piece, and the respective frontal end of the block being furnished with a
metal-cap;
Fig. 7 is another similar-view, the grooves being closed by a piece of sheet of
metal;
Fig. 9 is a frontal view of the form of construction shown in Fig. 7, and
Fig. 9 is a modification of the form of construction shown in Fig. 7, the piece of
sheet of metal being replaced by a wooden plate.
Referring to Figs. 1-4, a a¹ a² as a designate the laths, which are provided each
with either one longitudinal depression or cavity (compare the lath.a in Fig. 4,
and the laths a and a' in Fig. 2), or with two depressions or cavities b₁ (compare
the latis a' a in Fig. 4, and the lath a² in Fig. 3). Each two neighbouring of said
depressions or cavities are forming a groove or channel, which is closed at its
top by longitudinal projections a³, Figs. 3-7 & 9, and at its frontal ends by
projections a, Figs. 3 & 5, made all integrally with the material of the laths
proper.
Within the said grooves or channels bb, or bor
respectively, there are
arranged the rows of bristles or hairs c, Figs. 1, 2 & 5-9, which are held either
solely by the nails or splints d, Figs. 1 & 2, drawing the laths against one another,
or moreover by any glueing- or cementing-medium, as indicated by the dots in
Figs. 1, 2, 5-7 & 9
The projections as of the laths, which are made integrally with the latter, may
be replaced by separate pieces (as for instance e in Figs. 1 & 6) inserted into, and
fixed within, the ends of the grooves or channels bb, or bor b¹ respectively.
These pieces may consist either of hard material, as for instance wood, or of soft
one, as for instance putty or a similar stuff. Especially in this latter case, I prefer
to combine with the said pieces outer frontal mountings or fittings, which may be
constituted either by metallic caps f (Fig. 6), or by metallic plates f¹, Figs. 7 & 8,
or by wooden plates 2, Fig. 9. These mountings or fittings may be employed,
however, also directly for closing the grooves or channels, as is clearly shown in
Figs. 7 & 9.
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 [
claim is
1. In a broom or brush having its block composed of parallel laths holding
between them the bristles or hairs in rows, the combination with said laths, of
longitudinal projections adapted to close the intermediate spaces between the said
laths at the back of the block, for the purpose as described.
2. In a broom or brush having its block composed of parallel laths holding
between them the bristles or hairs in rows, the combination with said laths, of
projections adapted to close the intermediate spaces between the said laths at the
back of the block, as well as at the frontal sides of the same, for the purpose a
described.
3. In a broom or brush having its block composed of parallel laths holding
between them the bristles or hairs in rows, the combination with said laths o
longitudinal projections adapted to close the intermediate spaces between the said
laths at the back of the block, the frontal sides of the latter being provided with
mountings, for the purpose as described.
4. In a broom or brush having its block composed of parallel laths holding
between them the bristles or hairs in rows, the combination with said laths, of

page_text: projections adapted to close the intermediate spaces between the said laths at the
back of the block, as well as at the frontal sides of the same; said frontal sides
being provided with mountings, for the purpose as described.
5. In a broom or brush having its block composed of parallel laths holding
between them the bristles or hairs in rows, the combination with said laths, of
longitudinal projections adapted to close the intermediate spaces between the said
laths at the back of the block, the grooves thus formed between the laths being
closed at their frontal ends by separately inserted pieces, for the purpose as
described.
6. In a broom or brush having its block composed of parallel laths holding
between them the bristles or hairs in rows, the combination with said laths, of
longitudinal projections adapted to close the intermediate spaces between the said
laths at the back of the block; the grooves thus formed between the laths being
closed at their frontal ends by separately inserted pieces; the frontal sides of the
block being provided with mountings, for the purpose as described.
7. In a broom or brush having its block composed of parallel laths holding
between them the bristles or hairs in rows, the combination with said laths, of
longitudinal projections adapted to close the intermediate spaces between the said
laths at the back of the block; the grooves thus formed between the laths and
containing the upper ends of the cleansing-material, being filled up with a
cementing-medium, for the purpose as described.
8. In a broom or brush having its block composed of parallel laths holding
between them the bristles or hairs in rows, the combination with said laths, of
longitudinal projections adapted to close the intermediate spaces between the said
laths at the back of the block; the deepenings between the projections on either
side of the laths being arranged so as to cause the grooves formed by each two of
said deepenings to diverge from the closed to the open side of the block, for the
purpose as described.
9. In a broom or brush having its block composed of parallel laths holding
between them the bristles or hairs in rows, the combination with said laths, of
longitudinal projections adapted to close the intermediate spaces between the said
laths at the back of the block; the deepenings between the projections on either
side of the laths being arranged so as to cause the grooves formed by each two of
said deepenings to diverge from the closed to the open side of the block; said
grooves being closed at their frontal ends, and being filled up with a cementing-
medium, for the purpose as described.
