Improvements in Elbows or Bends for Suspending Hose Pipes.
WILLIAM PETT Chief Fire Brigade Station Exeter Devonshire Chief Officer
of Exeter Fire Brigade do hereby declare the nature of this invention to be as
follows:-
A metal tube elbow (or bend) having a female union or coupling at the inlet,
and a male union or coupling at the outlet, in the centre is a revolving watertight
joint for the purpose of allowing the top half of the elbow (or bend) to revolve.
Attached to the bottom half of the elbow (or bend) is a chisel pointed hook for the
purpose of admitting the round of a fire escape or ladder, the outlet and inlet being
of the same size, that is to say a full waterway elbow (or bend) to be used with
any sized hose pipe in the extinction of fires or other purposes. The object of
the elbow (or bend) is to suspend the hose pipe and conduct a full sized hose
waterway at an angle over the round of a fire escape or ladder when in an elevating
or elevated position, thus preventing loss of pressure by friction or depression.

COMPLETE SPECIFICATION.
Improvements in Elbows or Bends for Suspending Hose Pipes.
I, WILLIAM PETT of Chief Fire Brigade Station, Exeter, in the County of
Devon Chief Officer of Exeter Fire Brigade 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 an improved form of elbow or bend, having a female
union or coupling at the inlet, and a male union or coupling at the outlet, arranged
with a swivel joint and a hook for the attachment of the same to a fire escape
ladder, & is constructed as follows.
A cylinder A (Figs. 1 & 2) constructed of any suitable material but preferably
of gunmetal is formed with a hook B for ready attachment to any of the rounds of
a fire
escape ladder. At the lower end of the cylinder is attached in any suitable
manner a female union or coupling C to which a hose pipe can be attached. At
the upper
end of the cylinder is formed a stuffing box D in which works a swivel
joint E made to withstand water pressure by means of a gland F secured by
studs G. G.; and leather packing H.
Attached to the swivel joint E is the elbow K with the male connection L at its
upper end for the attachment of branch pipes nozzles &c.
It will be observed that the drawings show ordinary V thread screwed con-
nections at either end of the elbow, but I do not confine myself to this form of
coupling as the elbow is capable of being adapted to any form of coupling desired.
The advantages I claim for this form of elbow are as follows.
1. It can be used on any pattern fire escape & fixed to any round of the same.
2. It requires no fitting and is always ready for use.
3. It is adaptable to any form of hose coupling.
4. It obviates the necessity of strapping the hose to the ladder.
5. When on the escape the fireman is relieved of all weight, one hand only being
equired to work the iet

page_text: Having now particularly described and ascertained the nature of my inven-
tion & in what manner the same is to be performed I declare that what I
claim is.
1. An improved form of elbow with a full waterway, arranged for attachment to
the rounds of a fire escape ladder & with couplings at either end for the suspension
of hose and the attachments branch pipes nozzles &c.
2. The application of a swivel water tight joint to allow of the elbow being
turned in any direction.
