PROVISIONAL SPECIFICATION.
An Improved Herring-bone Strut or Bridging.
I, HECTOR GERMAN of Lindfield in the County of Sussex Surveyor do hereby
declare the nature of the said invention to be as follows:-
This invention has for its object an improved herring-bone strut or bridging
whereby great rigidity and strength is afforded to the joists. Heretofore it has
been the practice to use wood struts between the joists, and in order to keep said
wood struts in proper position nails or screws are employed whereby the wood is
liable to split and the support weakened.
According to my invention they are composed of any desired metal in preference
wrought iron. In carrying my invention into effect I take a piece of flattened bar
metal of the required length and bend the ends thereof about an inch more or less
in opposite directions and nearly parallel to each other, these ends have then cut
in their outer surfaces serrations or teeth for the purpose hereinafter described. I
also if desired drill a hole or holes in such ends to take uails or screws.
It is well known that the herring-bone strut or bridging takes the vertical strain
of the joists, therefore by my invention the serrations or teeth in the bent ends will
firmly embed themselves in the joists and by the aid of the screws or nails will
firmly and rigidly hold them in their proper position, thus there is no possibility of
them giving or yielding in any direction.
It will thus be seen that my improved strut or bridging will of itself carry the
weight or strain of the joists and at the same time will prevent by the aid of the
screws or nails any side slip or movement thereof.

COMPLETE SPECIFICATION.
An Improved Herring-bone Strut or Bridging.
I HECTOR GERMAN of High Street Lindfield in the County of Sussex Surveyor
do hereby declare the nature of the said invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement reference being had to the accompanying drawings and to the figures and
letters marked thereon:-
This invention has for its object an improved herring bone strut or bridging
whereby great strength and rigidity is afforded to the joists.
Heretofore it has been the practice to use wooden struts between the joists and
in order to keep the said wooden struts in proper position nails are employed
whereby the wood is liable to split and the support weakened, but according to my
invention they are composed of any desired metal in preference of cast or wrought
iron.
In order that my invention may be properly understood and readily carried into
effect I have appended hereto a sheet of drawings in which
Figure 1 shows a side elevation of a pair of struts in position and
Figure 2 is an elevation of one of the ends or enlargements.
In carrying my invention into effect I form a strut a either by casting or welding
having its ends a¹ enlarged and spreading out on each side about an inch more or
less the face of such enlargement is slightly curved and have formed therein
I also form in the
serrations or teeth a' for the purpose hereinafter described
sides of such enlargements slots as to receive nails or screws in the centre of each
strut a I form slots a to receive a bolt b and nut b¹.

page_text: It is well known that the herring bone strut or bridging takes the vertical strain
of the joists, therefore by the use of struts constructed according to my invention
the serrations or teeth a' formed in the enlarged ends a' will firmly embed them-
selves in the joists d and the screws or nails c will hold them in their proper
position. The bolt b and nut 61 tends to further strengthen such struts when in
position and it will be impossible for them to give or yield in any direction.
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. A metal herring bone strut or bridging having enlarged ends provided with
slots or holes to receive nails or screws and having their faces serrated substantially
as herein described and shown in the accompanying drawings.
2. The construction and arrangement of a herring bone strut substantially as
herein shown and described.
Dated this 13th day of September 1893.
HECTOR GERMAN.
