Improvements in Clips or Bands chiefly Designed for use in the
Construction of Scaffolding.
I, VICTOR BERRURIER, of Saint Cyr l'Ecole (Seine and Oise), in the Republic
of France, Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer
tained in and by the following statement:-
The present invention relates to a metallic band intended to supersede ropes
and other similar devices used in the binding together of the poles of scaffolding,
temporary huts, enclosures, floating bridges or rafts or other similar construction's.
This metallic band has the advantage that it is of greater durability than the
ropes usually employed, it is of less weight than chains or other securing devices
which are used in certain cases, it affords a more secure fastening, and protection
from atmospheric influences, and moreover it has the advantage of being adapted
to be put into place with greater ease and rapidity, compared with ropes, which
necessitates the exercise of a certain amount of skill.
In order that my invention may be readily understood I have represented the
same in the accompanying drawing, in which:
.
Figure 1 shows a front and a side view of a metal band, made in accordance
with my invention;
Figure 2 illustrates the band in use;
Figure 3 shows the use of the band for fastening a put-log to a pole in making
a floating scaffolding;
Figure 4 shows the use of the band for lengthening a scaffolding pole and
Figure 5 shows a modification of the metallic band.
any
The band shown in Figure 1 is formed of a metallic cable A, of suitable
make and length, provided at one of its extremities with a piece of chain B, con-
taining several links, and, at the other end with a plate C, in which is pivoted a
lever D, furnished with a hook a and a small hole b. The cable A is joined to
the chain by means of a splicing c and the cable and the plate C are joined at d
in the same manner. This plate is slightly curved, and is bifurcated at e, opposite
the cable, so as to form a forked joint for connecting the plate C with the lever D
which is likewise curved. The chain B serves as a length adjusting device and
the plate C serves to support the lever D when the latter is operated to produce
the desired tension.
Suppose it is desired to connect the two poles 1 and 2 Figure 2, the cable A is
passed one or more times around one of the poles and the ends of the said cable
are passed around the other pole. The chain B is hooked by one of its links on
to the hook a of the lever D, occupying the position shown in full lines, and in
such a way that the entire band is stretched as much as possible. As shown, the
chain regulates the length of the band. The lever D is now forced down on to
the supporting plate C and in this movement the hook a carries with it the end
of the band provided with the chain, while the other end is drawn in the contrary
direction. By this means the band is strained and drawn tightly around the poles
thus binding them securely together. To maintain the tension of the band and

page_text: prevent the loosening of the same I introduced into the small hole b, which is now
on the other side of the plate C, a pin which prevents the lever D from returning
to its original position.
By preference a split pin is used, the split ends of which may be turned out-
ward so as to prevent the accidental displacement of the said pin.
Figures 3 and 4 show, by way of example, two applications of this band. In
Figure 3 it is shown applied to the binding of a put-log, 3, to a pole 4, this figure
shows different views of the winding of the band. The same is also the case in
Figure 4, which shows different views of the winding of one pole, 5, to another
pole, 4, for the purpose of lengthening it.
Instead of using a length of chain for regulating the length of the band, a num-
bear of notches h, h, (Figure 5) may be made in the lever H, analogous to the above
mentioned lever D, and in one of which is hooked the terminal loop i, arranged
at one of the extremities of the band in place of the chain B.
Any suitable means may be used for fixing the lever H or D after tension instead
of the above mentioned pin use may be made of an S-shaped hook engaging at
the same time with both the cable A and the end of the lever.
It will be understood that the parts constituting the band may be made of any
metal and may be of any convenient shape and size, and that this band may be
used for joining together the parts of any structure, that is to say it may be used
wherever rope or other means of connection are employed.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is:-
1. A metallic band for binding together pieces of wood scaffolding poles or the
like characterised by a metal cable (A) at one end of which is connected a length
of chain (B), intended to serve as a length adjuster to be hooked to a lever (D),
joined to the other end of the said cable; this lever having a hook (a) to receive
one of the links of the chain (B) the said hook being adapted to be turned down,
to impart to the band the required tension, which is maintained by fixing the lever
in its bent down position, as above specified.
2. In the metal band, referred to in the first claim, the arrangement between
the lever (D) and the corresponding extremity of the metal cable (A) a plate (C)
intended to serve as a support for the said lever when it is turned down, and to
which is pivoted a hook on said lever having a hole (b) therein into which a pin
is placed for the purpose of securing the said lever in its turned down position,
as specified.
3. In the metal band referred to in the first claim, the substitution of a simple
buckle loop for the chain (B), which loop hooks into one of the notches (h) made in
the tension lever (H); the row of notches therein acting as means of adjustment
as specified.
