Improvements in Machinery Used when Rivetting Together Metal
Plates in the Manufacture of Girders and such like.
We, HARRY TURNER SHAW and CHARLES CHITTICK both of 141 and 143 Cannon
Street in the City of London, Engineers, do hereby declare the nature of this
invention to be as follows:-
_:
The object of the invention is to provide machinery by which hydraulic tools
such as rivetters punches or drills &c. can be shifted readily for making holes for and
putting in rows of rivets when forming girders and such like.
The work to be rivetted is erected between gantrys set at a distance apart. A
traveller resting on rails at the top of or preferably fixed to the inner sides of the
gantrys and bridges over the space between them. This traveller not only has the
hydraulic rivetting or other tools suspended from it but also carries a roof under
which men can work at all times and in all weather. If the rails are fixed to the
inner sides of the gantrys then the ordinary lifting traveller crane used with the
gantrys and which ordinarily runs on rails along the top is able to pass clear of
the new traveller. The traveller carrying the roof and hydraulic tools is composed
of two main parallel girders tied together at a distance apart from one another. To
the top of these girders are secured a number of parallel purlins for forming a roof.
The purlins not only extend across the space beyond the two main girders of the
traveller but also extend for a distance round each of these girders-corrugated
iron or other roofing material is carried by the purlins.
Below the main girders of the traveller and at right angles to them is a long
horizontal beam which extends not only across the space between the two main
girders but also for a distance beyond them-this beam is suspended from wheels

side to side and over the whole space covered by the traveller as may be desired.
One or more hydraulic rivetters or other tools may be suspended from this long beam
and may be traversed along it whilst a row of rivets or holes is being put into any
girder or other structure which is being put together.-Preferably we suspend from
the main girders of the traveller two such beams each carrying one or more rivetters
or other tools.
The traveller with its roof and rivetters and other tools can be moved to any part
of the gantry wherever the work may be erected and as before stated does not
interfere with the ordinary lifting traveller being used on other parts of the
gantry.

We, HARRY TURNER SHAW, and CHARLES CHITTICK, both of 141 and 143 Cannon
Street, in the City of London, Engineers, 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 :-
The object of the invention is to provide machinery by which hydraulic pneu-
matic or other power tools such as rivetters punches or drills &c. can be shifted
readily for making holes for and putting in rows of rivets when forming girders
and such like.
The work to be rivetted &c. is erected between gantrys set at a distance apart.
A traveller resting on rails at the top of or preferably fixed to the inner sides of the
gantrys and bridges over the space between them. This traveller not only has the
hydraulic rivetting or other tools suspended from it but also carries a roof under
which men can work at all times and in all weather. If the rails are fixed to the inner
sides of the gantrys then the ordinary lifting traveller crane used with the gantrys
and which ordinarily runs on rails along the top is able to pass clear of the new
traveller. The traveller carrying the roof and hydraulic tools is composed of two
main parallel girders tied together at a distance apart from one another. To the
top of these girders are secured a number of parallel purlins for forming a roof.
The purlins not only extend across the space between the two main girders of the
traveller but also extend for a distance beyond each of these girders corrugated iron
or other roofing material is carried by the purlins.
Below the main girders of the traveller and at right angles to them is a long
horizontal beam which extends not only across the space between the two main
girders but also for a distance beyond them-this beam is suspended from wheels
which run on the bottom flanges of the main girders so that it can be moved from
side to side and over the whole space covered by the traveller as may be desired.
One or more hydraulic rivetters or other tools may be suspended from this long beam
and may be traversed along it whilst a row of rivets or holes is being put into any
girder or other structure which is being put together. Preferably we suspend from
the main girders of the traveller two such beams each carrying one or more
rivetters or other tools.
The traveller with its roof and rivetters and other tools can be moved to any part
of the gantry wherever the work may be erected and as before stated does not
interfere with the ordinary lifting traveller being used on other parts of the
gantry.
The drawings hereunto annexed shew machinery constructed as above described.
Figure 1 is a plan view with the roofing on the right hand side of the traveller

page_text: Figure 2 is a transverse vertical section.
A A are the parallel sides of a gantry which may be an ordinary existing gantry-
B B are rails carried by projections from the inner sides of the gantrys. The
traveller which is capable of travelling along these rails is composed of the two
main parallel girders CC which are tied together at a suitable distance apart and
mounted on wheels to run on the rails-D D are the roof purlins secured to the tops
of the girders and extending beyond them-E is the roof covering carried by the
purlins F F are two horizontal beams each of which is suspended from wheels which
run on the bottom flanges of the girders (-G G are hydraulic rivetters suspended
from the beams F and capable of being traversed to and fro along them-There may
as above stated be one or more rivetters carried from each beam-the drawings shew
one only. K K are wind ties.
Water under pressure used for working the rivetters may be led to the rivetters in
any suitable manner. In the drawings we have shewn it as being carried to them
through jointed pipes H-It is carried up first to one end of one of the girders C and
then partly along this girder and by jointed pipes to one of the beams F and along
this beam to its centre where by other jointed pipes it is led to the truck from which
the rivetter is suspended and from there it is conveyed to the rivetter either through a
flexible or jointed pipe as may be preferred.
II are supports for the jointed pipes, J J are rails mounted as usual along the tops
of the gantrys for carrying an ordinary lifting traveller. In place of the tools being
worked by hydraulic power they might be worked by pneumatic or other power.
In a similar manner also punches, drills or other tools may be suspended from the
beams F so that they can be brought into any position between the lines of rails
upon which the traveller moves and be similarly worked by power.
In place of the traveller being supported by rails on gantrys it might be carried
upon vertical supports with wheels running on rails at or near the ground level in the
manner of an ordinary Goliath crane.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. The combination of the traveller formed of parallel girders tied together and
capable of travelling along a gantry or railway-the beam or beams at right angles
to these girders and capable of being traversed to and fro along them and power
rivetters punches drills or such like power tools suspended from the beam or beams
and capable of being traversed along thom so that they command the whole area
between the lines of railway.
2. Machinery constructed substantially as herein before described and illustrated
in the drawings annexed to be used when rivetting together metal plates in the
manufacture of girders and such like.
