ing which illustrates a‘pre‘ferred form of this in
It is an object of this invention to provide a vention with the understanding that detail
tool of this character which is simple in con- ~
struction and operation and which may be readily
, adapted for use as a brush or shovel by causing
a slight change in the horizontal relation be
tween the parts and then a reversal in their ver
tical relation to place the desired tool in opera
tive position. It is a further object to so mount
the two tools upon the samehandle to be mov
15 able in relation to each other and to the handle,
yet to allow either to be used in its normal man
ner without changing the angular relation of
the handle to the ground from that customarily
employed in the operation of either tool. It is
20 also an object of this invention to provide de
tachable means to secure rigidly the tools upon
the handle in either position, and when detached
. to employ a rotative movement of the handle to
assist the changing of the relation of the tools
to each other. It is a still further object to pro-‘
vide a brush with detachable and interchangeable
bristles so that they may be replaced when worn
out or’interchanged when partially worn.
The advantages of such a tool are obvious, and
its uses are many. While originally contemplated
for the use of the men employed to keep the
streets of a city clean, it may be used in the
same manner in cleaning sidewalks, hallways and
, o?ices of buildings, gardens or other places where
changes may be made without departing from
the scope thereof, and with the understanding
that the brush with the interchangeable and re
placeable bristles, while preferable, may be re 10
placed by a brush of the ?xed bristle type without
departing from the scope of this invention.

In the embodiment of this invention as illus
it is desired to brush surface dirt or debris into
small piles, and then shovel the pile into a re
trated, the brush I may be of the customary push 35
ceptacle for removal. Therefore, this tool is also
the ‘transverse rows of bristles embedded'there
in, but it is constructed preferably of ‘a metallic
available for home use in the manner of a broom
and dust pan. The combined tool is balanced
40 on the handle so that each may be used in the
usual way without inconvenience or causing an
broom type having a wooden base or back with
casing having a flat rectangular base or back
2 closed at the front and the two short sides for 40
detachably mounting rows of bristles 3 arranged
unnatural position of the operator, as well as be
ing readily changed from one to the other with
little effort on the part of the operator on ac
45 count of the lever action of the handle in mak
ing a change. It has been found that the bristles
in brushes customarily used for this purpose, and
which are usually formed in parallel transverse
rows, wear unevenly, that is, either the front or
ing out turned ?anges 5 along the free edges of 45
rear rows wear sooner than the intermediate rows
50.
according to the manner in which the operator
holds the handle. Therefore, a brush which is
parallel to‘ the long closed front, as hereinafter
described.
‘A shovel 4, preferably of stamped metal, hav
the sides is mounted upon the back 2 of the
brush l with the ?anges 5 engaging in guides 5
provided therefor and secured upon the back 2
so that the shovel may be retracted to position
its front approximately in line with the front of
the brush, as shown in Figure 1, when the tool
is to be used as a push broom, the guides 6 being
provided with bristles formed in sections and de _ extended, preferably, at the rear of the back ‘2
tachably secured in the frame of the brush allows to provide rigidity to the connection of the shovel
the interchange of partially worn bristles and
4 to the brush I in this position.
The exterior 55

surface of the back 2 is provided, preferably
with an external rib 1 arranged adjacent and
parallel to the long closed front between the sides
of the shovel 4 to be engaged by the rear end
of the shovel to limit its outward movement
when the shovel is extended, as shown in Figure
3, when the tool is to be used as a shovel.
The brush I mounting the slidable shovel 4
upon its back is attached to a handle 8, which
10 may be of wood or whatever material desired, by
providing a metallic sleeve or ferrule 9 to receive
the end of the handle 8 which may be attached
thereto in any desired manner. The handle
ferrule 9 is pivotally attached to the back 2 of
15 the brush I by a frame or bail ID, the free ends
of which are preferably out-turned and received
in bearing II therefor secured to the back 2 and
the center portion attached to the ferrule 9, as
shown.
To secure the handle 8 in proper relation to
the tool when used either as a push broom or as
a shovel and to assist in changing the movable
relation between the shovel and brush, a con
necting link I4 is provided which is mounted to
slide within a guide I5 mounted longitudinally
upon the ferrule 9. The link I4 is preferably
circular in cross-section with one end having a
sliding connection I6 with the back of the shovel
4 and the opposite end provided with an operat
ing pin or handle I‘! adapted to travel in a lon
gitudinal slot I8 provided therefor in the guide
l5 which slot is provided at each end with an off
set portion I9 to receive the handle I‘! and hold
it at each’ end of travel.
In the position'shown in Figures 1 and 2, the

a requirement for division made in this applica
tion. In this type of brush, the bristles are
formed in narrow rectangular sections with the
upper ends held together by glue or embedded in
cement or other similar medium. The sections U!
are of such length as to be receivable between
the side closures 20 depending from the flat back
2.
The front section of bristles 3 is held in posi
tion against the front closure 2| depending from
10
the ?at back 2.
As many partitions 22 are provided parallel to
the front closure 2| as there are sections of bristles
to be employed. These partitions 22 are equally
spaced apart from each other and the front
closure 2| and their ends are secured in any de
sired manner to the depending side closure 20.
The embedded ends of the section of bristles 2
are inserted to rest against the front closure 2i
and each of the partitions 22 and secured thereto
in that position by a series of adjustable follower
plates 23 preferably mounted upon guides 24 vpass
ing freely through the partitions 22 and secured
to each follower plate 23, as shown in detail in
Figure ll. When the brush sections are in place,
the embedded ends are secured against the respec
tive partitions 22 and front closure 21 by exerting
pressure upon the guides 24, as by screws 25 freely
mounted upon the outer follower plate threaded
into the next adjacent ?xed partition 22, or by any
other desired means, so that the bristles 2 are
rigidly held in position and yet may be detached
and removed for reversal or interchange with
another section.
What I claim is:
1. An attachment for a ?at backed brush or
tool is adjusted for use as a push broom with the
the like having a handle pivoted thereto, including
shovel 4 retracted and the link I4 withdrawn
Within its casing I5 and the handle I1 held in
locked position in the off set slot I9 furthest
140 from the shovel 4. When it is desired to change
the tool to a shovel, the handle 8 is depressed and
rotated about the bearings I I which will initiate
the extension of the shovel 4 in its guides 6
through the locked link I4. The handle I‘! of
the link I4 is then rotated out of its locked posi
tion and is manually advanced in its slot I8 until
the rib ‘I is engaged with the back of the shovel
an inverted scoop shaped shovel mounted on the
back of said brush, means engaging and guiding
the open side edges of the shovel to slide upon the
back of the brush, and a connecting link attached
to the back of the shovel mounted to slide length
wise upon the said handle to extend and retract
4. The tool is then in position to be used as a
shovel and is turned with the bristle side of the
brush I upward, as shown in Figures 3 and '7.
The securing of the link handle I‘! in the off set
I9 nearest the shovel 4 locks the tool with the
brush and shovel in proper relation.
As heretofore stated, it is preferable to employ
the particular construction of brush here illus
trated which is disclosed and claimed in the ap
plicant’s Patent No. 2,112,297, granted March 29,
1938, upon an application ?led in accordance with
2.5

3.5
the shovel over the back of the brush, and means
to secure the link to the handle at the respective
ends of its travel.
2. The structure of claim I wherein the end of
45
the handle is provided with means mounting a
sleeve for slidably receiving one end of the con
necting link, the other end of the connecting link
having a sliding connection with the back of the
shovel, said sleeve having a longitudinal slot
therein with offsets at each end thereof, and an
operating handle mounted upon the received end
of the link passing through the slot in the sleeve
and adapted to secure the shovel at the op 65
posite ends of travel of the link by engaging said ’ '
link handle in a transverse offset.
