COMPLETE SPECIFICATION.
Improved Devices for Facilitating the Cleaning of Tubes.
ALLAN STIRLING, 6 Montague Street, Russell Square, W.C. London, 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 certain improved devices for facilitating the cleaning
of tubes and to modifications of or improvements in the devices for facilitating the
cleaning of tubes such as are described in the British Patent Specification
No. 12,649 of 1895, the improvements which constitute the invention are pointed
out in the following specification and claims and illustrated in the accompanying
drawings in which Figs. 1. 2. 3 & 4. represent modifications of or improvements in
the devices described in British Patent Specification No. 12,649 of 1895 and
Fig. 5, represents an improved device.
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repeated.
In the modification shown in Fig. 1. the tube has a screwed end d. for the
purpose of securely attaching the cap D. The end of the tube may be made
larger than the body of the tube and a ferrule f may be inserted in the tube
plate A to fill the enlarged hole, the cap D is secured to the screwed end of the
tube by the coupling e, or the cap D may be secured to the tube by clamps, or
suitable means may be used for securing the cap D to the unscrewed enlarged end
of the tube.
The cutter a is made in a separate piece from the scraper C, and this cutter a.
is secured by a cap b.
In the modification shown in Fig. 2. the scraper C. is perforated, water or other
fluid is admitted through the hollow plug or cap D. to the tube B. and through
the perforated scraper C. for the purpose of facilitating the removal of the foreign
matter.
In the modification shown in Figure 3, water or other fluid is admitted to the
tube at either end by the pipe P. or other device for the purpose of facilitating the
removal of the foreign matter.
In the modification shown in Figure 4, the cutter a. is made in a separate piece
from the scraper C. and is secured by the nut or cap h. Passages i are provided
to the perforations in the scraper C. The nuts or caps h and I are perforated at r,
so that any dirt in the threads may readily pass out. The links j & m. form the
guides for the scraper C. The scraper may be removed from the chain by
unscrewing the bolt k. without unscrewing the scraper C from the nut h. A bolt p.
& nuts and o. are provided to protect the parts k. l & w. when they are not
coupled together & the tail chain u. of the scraper C is arranged for the return of
the bolt p. & nuts q. and o.
In the improved device shown in Fig. 5. a cutter or drill s. is attached to a
flexible shaft t. This flexible shaft is caused to revolve and the cutter is moved
into the tube and removes the foreign matter. Water or other fluid may be
introduced into the tube at either end through a pipe or through an annular
nozzle v.

page_text: 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. In apparatus for facilitating the cleaning of metal tubes, the combination
with the tube B. scraper C. hollow cap D. pipe E. and means for imparting motion
to the scraper C. by fluid pressure, of the screwed end d. and coupling e substantially
as described.
2. In apparatus for facilitating the cleaning of metal tubes, the combination
with the tube B. scraper C. hollow cap D. pipe E. and means for imparting motion
to the scraper C. by fluid pressure, of the screwed end d, coupling e, and ferrule f.
substantially as described.
3. In apparatus for facilitating the cleaning of metal tubes, the combination
with the tube B. scraper C. hollow plug D. pipe E and means for imparting motion
to the scraper C. by fluid pressure, of means for clamping the cap D. to the
tube B.
4. In apparatus for facilitating the cleaning of metal tubes, the combination
with the tube B. scraper C. hollow cap D. pipe E, and means for imparting motion
.to the scraper C. by fluid pressure, of an enlarged end to the tube, the ferrule f
and means for securing the cap D. to the enlarged end of the tube.
5. In apparatus for facilitating the cleaning of metal tubes, the combination
with the tube B. & scraper C. of the cutter a. substantially as described.
6. In apparatus for facilitating the cleaning of metal tubes, the combination
with the tube B. & scraper C. of the cutter a. and means for securing this scraper
to the cutter C. substantially as described.
7. In apparatus for facilitating the cleaning of metal tubes, the combination
with the tube B. and perforated scraper C. of the chain K. substantially as
described.
8. In apparatus for facilitating the cleaning of metal tubes, the combination
with the tube B. and perforated scraper C. of the chain K. the wheel M and
means for imparting to the wheel M a rotary motion substantially as described.
9. In apparatus for facilitating the cleaning of metal tubes, the combination
with the tube B. and perforated scraper C. of the hollow plug or cap D.
substantially as described.
10. In apparatus for facilitating the cleaning of metal tubes, the combination
with the tube B. and perforated scraper C. of the pipe P. substantially as
described.
11. In apparatus for facilitating the cleaning of metal tubes, the combination
with the tube B. and perforated scraper C. of the cap h. and passages i. substantially
as described.
12. In apparatus for facilitating the cleaning of metal tubes, the combination
with the tube B. and scraper C. of the links; & m. substantially as described.
13. In apparatus for facilitating the cleaning of metal tubes, the combination
with the tube B. and scraper C. of the nut h. bolt k. and nut e, substantially as
described.
14. In apparatus for facilitating the cleaning of metal tubes, the combination
with tube B. scraper C, nut h. bolt k and nut e. of the bolt p. chain u, and nuts q
and o, substantially as described.
15. In apparatus for facilitating the cleaning of metal tubes, the combination
with tube B. of cutter s. and flexible shaft t, substantially as described.
16. In apparatus for facilitating the cleaning of metal tubes, the combination
with tube B. cutter s. and flexible shaft t. of means for introducing water into
the tube substantially as described.
