Improvements in Tube-cleaners.
CHRIST. GOTTLOB MUNZENMAIER, Kennenburg, Wurtemberg, Germany,
Artisan, and HUGO SPRAUDEL, Esslingen, Wurtemberg, Germany, Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention consists in the construction of an apparatus for cleaning the inside
of tubes or pipes of any description, such as boiler tubes, heating, and chimney
pipes, and is adapted for use with the boiler tubes of portable and locomotive
engines.
The cleaner is composed of two or more series of segments of circles arranged
elastically around a central rod or handle. When the device is moved to and fro
in the tube, the inside of same is cleaned, owing to the segments being pressed
against the inside of the tube by the action of springs.
In order that our invention may be more fully understood we now refer to the
accompanying drawings. Similar letters of reference refer to corresponding parts.
Fig. 1 shows our cleaner in plan.
Fig. 2 is a longitudinal section along line aß in Figure 1.
Fig. 3 is a cross section through line A. B Figure 2.
Fig. 4 is an end view of device.
Fig. 5 is a cross section showing the apparatus inside a tube.
Referring to Figures 1 and 2, on the rod a, are mounted in any convenient
manner the guide flanges b, b, for guiding the segments ff. Between the guide
flanges f, f, the rod a has a square or rectangular section, and
The
provided with
heads cand c¹. The head c is forged or cast on the rod and is fitted to allow the
handle to be screwed into it the head c¹ being screwed on to the rod a.
surfaces of the heads which face one another, are turned out so as to leave a rim
round the edge of the same as shown in Figure 2. The segments f, f, are con-
nected together by means of the ribs e, e. These 4 segments are guided in the
flanges b, b, the ribs e, e, engaging in the slits, (or sliding in same in flanges b, b).
The connecting ribs e, e, are tapered at their ends and adapted to pass under the
rims on the heads c, c¹. Each segment is pressed outwards against the sides of the
tube through the medium of the connecting ribs e, e, actuated by the flat springs d, d,
having their ends slotted to engage with the said ribs e, e.
It will be seen that when the apparatus is passed into a tube, the springs d, d,
will be compressed and the segments will adapt themselves to the diameter of the
tube, being pressed against its inside through the action of the springs d, d, and
thus will remove any incrustation or dirt, upon the apparatus being moved to and
fro through the tube. The segments may be made of any suitable material and any
convenient number may be employed.

Improvements in Tube-cleaners.
We, CHRIST. GOTTLOB MÜNZENMAIER, Artisan, of Kennenburg, and HUGO
SPRAUDEL, Engineer, of Esslingen, Kingdom of Wurtemberg, in the German
5 Empire, do hereby declare the nature of our said invention for IMPROVEMENTS
IN TUBE CLEANERS and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
Our invention consists of an apparatus for cleaning tubes and pipes of every
Price $1

page_text: description such as boiler tubes, heating and chimney pipes, and is particularly
adapted for boiler tubes of portable and locomotive engines.
The cleaner is formed by two or more series of segments of circles arranged
elastically around a rod or handle and adapted to press against the insides of the
tubes whilst be moved backwards and forwards in the same and thus effectually
removing any incrustations or dirt.
1.
In order to make our invention more clear we refer to the drawings left with our
Provisional Specification in which similar letters denote similar parts throughout
the several views.
Fig. 1 shows a plan of the cleaner.
Fig. 2 is a longitudinal section along line a ẞ in Fig. 1.
Fig. 3 is a transverse section on line A B Fig. 2.
Fig. 4 is an end view.
Fig. 5 is a transverse section showing the apparatus inside the tube.
Referring to Figs. 1 and 2; on rod a are mounted in any convenient manner
the guide flanges bb for the segments ff; rod a has a rectangular section between
the guide flanges and is provided at each end with a head c and c¹. Head c is
forged on the rod and so formed that the handle of the cleaner may be screwed
into it whilst head c¹ is screwed on to rod a. The surfaces of the two heads which
face each other are turned out hollow so as to leave a rim round the edge of the
same as may be clearly seen from Fig. 2. The segments ff are connected together
by means of the ribs e e. These segments,-four in number,-are guided in the
flanges bb, the ribs e e passing into the slits in flanges bb; the connecting ribs e e
are tapered at their ends and adapted to pass under the rims of the heads c c¹.
Each segment is pressed outwards against this rim by the flat spring d d, which
rest on the rod a and have slits in their ends into which the ribs e e pass.
When now the apparatus is passed into a tube, the springs d d will be com-
pressed and the segments will adapt themselves to the diameter of the tube being
pressed against its insides by the springs.
On moving the cleaner backwards and forwards in the tube, all incrustations or
dirt of any description will be effectually removed.
We do not confine ourselves to any particular number of segments or springs,
reserving ourselves the right of arranging 6 or 8 segments around the rod a instead
of 4 as shown in the drawings.
tố
The segments may easily be exchanged or renewed, it only being necessary
screw off head c', take out the segment in question and place the new one in position,
when the head may be readjusted.
Having now particularly described and ascertained the nature of our said
invention and the manner in which it is to be performed, we declare that what we
claim and desire to secure by Letters Patent is :
In tube cleaners.
1. A series of segments provided with ribs in combination with a rod or handle
having flanges with slits for the reception of the segment ribs, flat springs tending
to press the segments outwards, and heads c and c¹ for the purpose substantially as
described.
2. The combination of segments ff having ribs e e guided in flanges b b of rod
or handle a, the flat springs d d for pressing the segments outwards and the heads c c¹
for the purpose substantially as described.
