I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors 6, Lord Street Liverpool and 6, Bank Street Manchester, both in the
County of Lancaster & 323 High Holborn in the County of Middlesex, Civil
Engineer 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 :-
•
A pipe staple made in accordance with this invention is in three main parts two of
which enclose the pipe and the third forms the locking link.
In the accompanying drawings
Figure 1 is a cross section of a pipe with the pipe staple placed over it and ready
for closing.
Figure 2 a side view of the pipe staple.
Figure 3 a side view of the pipe staple showing the hinge with the locking
link.
Figure 4 an end view of the pipe staple locked.
Figure 5 side view of the same, showing the method of locking.
Figures 6 and 7 are end and side views of a modification of the locking
apparatus.
The pipe R is embraced by the two loops a and b. On the loop a is a spike d
which is adapted to be let into the wall. The loops b and a are hinged together so
that the pipe R will rest in the loop a; e is the hinge.
The locking loop e is also hinged to the loop a by means of a
hinge a¹ in such
manner that a portion c¹ of the loop c will project beyond the hinge a¹ so that it
forms a lever, the longer arm c of which is separated from the shorter arm c¹ by the
inge a¹. The loop bends outward at and forms a support for the shorter lever
bent part b¹ and closes the loops a and b
rm c¹. This latter presses against the said

page_text: round the pipe R. The locking loop c is pointed at its free end so that by reason
of the lateral play of the said loop it can easily he pushed into the hook 6 placed on
the loop b, the pipe staple is thus effectually locked.
Any other suitable locking device may be used instead of that above described, as
for example that shown in Figures 6 and 7,.in which the curved end c² of the loop c
is shown pushed over the hinge e and is held sufficiently safely by its own
elasticity.
When it is required to set the pipe free, it is only necessary to disconnect the
part c² from the hook 2 or, in the case shown in Figures 6 and 7, to lift it off the
hinge e and then to turn the locking loop c to the right and the loop 6 to the left.
All this can be done by the hand or with a simple rod or nail. A great advantage in
the use of this staple, besides, the fact that it can be so quickly adjusted, is that it
can be adjusted without the use of tools.
Having now particularly described and 'ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is.-
1. A pipe staple composed of three main parts, one of which a is fastened at a
given point and supports the pipe, the said part a being connected at one end with a
second part b, by means of a hinge e and at the other end with a third part c by
means of a hinge a¹ in such a manner that the hinge al divides the locking link into
two arms of a lever c and c¹ the shorter arın c¹ of which draws the part b tightly
round the pipe R, the locking loop itself being held firmly closed, by a hook
equivalent, substantially as described and shown.
2. The improved pipe staple, substantially as described and shown.
