Improvements in Hydraulic Brushes.
I, THOMAS BRAYSHAW, of 66, Cromwell Road, Patricroft, in the County of
Lancaster, White-smith, 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 :-
My invention relates to that class of hydraulic brushes in which the water is
ejected against the object to be cleaned in advance of the bristles.
The objects of my invention are to render the said brushes more durable and
effective than heretofore has been the case and to adapt the same for the reception
of soap or other cleansing agents to mix with the water in an automatic and
continuous or intermittent manner.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Figs. 1 & 4 are end views, Figs. 2 & 6 are back views and Figs. 3 & 5
longitudinal sections of various forms of hydraulic brushes constructed in
accordance with my invention.
Referring to the figures generally a is the handle, b, b¹ the head, c are the
bristles, and d the spray or jet pipe of the brush.
In carrying out my invention I employ the spray or jet pipe d through which
the cleansing fluid is ejected, in a recess e formed in the front of the brush head b
which recess holds the pipe d firmly in position and prevents damage to the same.
On the pipe d is formed in T fashion a branch d¹ which may be either fitted into a
hole f formed crosswise in the brush head b, see Figs. 1, 2 & 3, or into a recess f¹
on the back of the same, see Figs. 4, 5, 6, & 7, and secured therein by such as a
strap 9 and suitable fastenings, the pipe d' being fitted to the tubular handle a of
suitable length and the latter coupled to with a flexible pipe h. The spray or jet
pipe d is formed with one or more rows of perforations * so positioned as to eject
the fluid onto the object to be cleaned in advance of the bristles e, the handle a
being furnished with a tap a¹ which permits the cutting off of the fluid supply as
may be required.
When fitting the branch pipe d¹ through the brush head b, I secure to the
rear of the same a plate & which retains the branch pipe d¹ in position.
In lieu of fixing the bristles c direct into the brush head they are fixed into a
separate piece b' which is rendered removable on the part 6 of the brush head by
screws or otherwise for the purpose of renewal.
In order to permit of supplying the spray or jet pipe d with a mixture of water
and soap or other cleansing agents in an automatic manner I form the brush head b
hollow, see Figs. 3, 5 & 6, so as to serve as a receptacle i for soap or other
cleansing agent which is introduced into the same through holes provided with
plugs m.
The branch pipe d' may either be fitted through the receptacle i, as shown in
Fig. 3, or into the recess f¹ in the back thereof, as shown in Figs. 5 & 6, the
respective portion of the pipe d¹ being in each case formed with suitable
perforations d², similar as shown in Fig. 3, so as to cause the water in passing
through the pipe d¹ to draw a certain amount of the said cleansing agent from the
receptacle i. In order to adapt the hydraulic brush described for the alternate use
of water or water and soap or other cleansing agent mixed I employ the tap a¹
close to the brush head b, b¹ and connect to the receptacle i and the pipe d' at the
rear of the tap a' a branch pipe n having a tap n', two bent pipes o, o being also

page_text: connected to the spray or jet pipe d and the receptacle i, so that when the tap a¹ is
closed and the small tap n opened the water is caused to pass through the
receptacle i and enter the spray or jet pipe d through the pipes o, o, whilst when
the tap al is opened and the small tap n closed the water will pass direct to the
spray or jet pipe d.
The bristles c may be fixed into the brush head b, b', at a right or any other
suitable angle to the brush handle a.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim, is-
"In hydraulic brushes,"
1st. The general construction and combination of parts constituting my improve-
ments all substantially as set forth.
2nd. The spray or jet pipe d fitted into a recess e in the front of the brush
head b, b', and having a branch d' fitted into a hole f¹ formed through the brush
head b, b, or in a recess f¹ in the same, substantially as set forth.
3rd. The brush head having a removable part which carries the bristles c,
substantially as and for the purpose set forth.
4th. The brush head b formed hollow for the reception of soap or other cleansing
agent adapted to mix automatically with water passing through the supply pipe d³,
substantially as and for the purpose set forth.
5th. A hydraulic brush as specified in the preceding claim, with means for
changing the supply of fluid, substantially as and for the purpose set forth.
Dated this 10th day of May 1894.
