PROVISIONAL SPECIFICATION.
Improvements in Machinery used in the Manufacture of Wheels
for Railway Vehicles.
I EDWIN DEARDEN, of Daisy Bank, Darnall, Sheffield, in the County of York.
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in machines used for welding the parts
of a wheel where the spokes join the rim by processes known as glutting or
dabbing on.
In the improved machine the subject of this invention the general arrangement
of the standards is substantially similar to the arrangement described in the
Specification to my Patent No. 818 dated February 14th 1883; but I now modify
the arrangement of the lever or double arm which carries the front tool, by making
the said lever or double arm longer and connecting it to a hydraulic or other
suitable motor, in such a manner that its motion may be separate and independent
of the motion of the main ram which carries the top tool.
Another part of this invention consists in forming grooves in the main standards
near the bottom to admit of a carrier working therein; to this carrier is secured a
centre pin, or mandril, on which the boss of the wheel to be glutted is placed, the
carrier being set in the grooves by means of one or more setting screws, or
otherwise, so that it can be readily raised or lowered to suit the dimensions of the
wheel to be glutted or dabbed on.
Dated this Twentieth day of February 1891.
COMPLETE SPECIFICATION.
Improvements in Machinery used in the Manufacture of Wheels
for Railway Vehicles.
I EDWIN DEARDEN, of Daisy Bank, Darnall, Sheffield, in the County of York,
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 :-
This invention relates to improvements in machines used for welding the parts
of a wheel where the spokes join the rim by processes known as glutting or
dabbing on.
In the improved machine the subject of this invention the general arrangement
of the standards is substantially similar to the arrangement described in the
Specification to my Patent No. 818 dated February 14th 1883; but I now modify
the arrangement of the lever or double arm which carries the front tool, by making
the said lever or double arm longer and connecting it to a hydraulic or other
suitable motor, in such a manner that its motion may be separate and independent
of the motion of the main ram which carries the top tool.
Another part of this invention consists in forming grooves in the main standards
near the bottom to admit of a carrier working therein; to this carrier is secured a
center-pin, or mandril, on which the boss of the wheel to be glutted is placed, the

page_text: carrier being set in the grooves by means of one or more setting screws, or
otherwise, so that it can be readily raised or lowered to suit the dimensions of the
wheel to be glutted or dabbed on.
In order that my invention and the carrying out of the same may be fully
understood, I have illustrated it in the accompanying drawing upon which
Figure 1 shows my improved arrangement for operating the front tool by
the action of a hydraulic piston or ram D, this motion being entirely independent
of the motion of the main ram which carries the top tool A. This view shows the
arrangement with the front tool B in the forward or open position ready to receive,
the wheel center requiring to be glutted, and Figure 2 represents the arrangement
with the front tool B closed up to the bottom tool A!; and the top tool A. also in
the closed position having the wheel center compressed to the required dimension
and form.
Figures 2 and 3 illustrate the second part of my invention, that is, the carrier H
baving a pin or mandril F secured therein, on which pin or mandril the wheel
center intended to be glutted is placed. The said carrier His made to slide up or
down in grooves provided in the standards of the machine, and I use one or more
setting screws J by which to raise or lower the said carrier to suit the diameter of
the wheel center to be glutted. This arrangement greatly facilitates the operation
of setting the combination of tools so as to ensure more accuracy in the work and
is easily adapted for altering to suit the various diameters of wheels.
On Figures 1 and 2 is shown a forked lever G which works loosely on a stud
fixed to the main standards. This is for the purpose of raising the lever or arm
carrying the front tool B so as to allow space for the wheel center to be placed on
the bottom tool A¹; this might be accomplished in various other ways.
The process or operation of glutting with these arrangements may be described.
as follows, that is to say :-
The
The wheel center being suspended from a crane and on suitable slings or portar
bar, according to the weight or dimensions, and having been heated to a welding
heat at the part to be glutted, and the bar or piece of iron intended for filling up
the space at the junction of the spokes and rim of the said wheel center also having
been heated ready for welding therein; the wheel center is brought and placed in
position in the tools which are open to receive it, as shown at Fig. 1.
pressure water is admitted first to the cylinder which operates the ram D, which on
ascending and acting through the levers E, brings the front tool B into the position
as shown at Fig. 2. During the time the said motion is taking place, the water is
admitted to the top or main cylinder to bring down the ram which carries the top
tool A, and the bar or piece of irou is also placed on the part to be welded or
glutted up so that the said top-tool will in its descent cut off the required portion
and then finally resting on the material with its full force complete the welding and
at the same time form or mould the rim of the wheel center to the proper form and
radius. When the pressure is removed and the water allowed to escape, the
reverse motion of the levers and also the raising of the top ram and the tool
take place, the wheel center is taken away and prepared for a repetition of the
process.
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. The arrangement in a wheel glutting machine, of levers operated by a piston
or ram for closing and opening the side tools independent of the motion of the
ram which carries and operates the top tool, substantially as hereinbefore described
and illustrated on the accompanying drawing.
2. The arrangement in a wheel glutting machine, of a carrier having a pin or
mandril, such carrier resting on or supported by one or more setting screws by
which it may be regulated to suit the various diameters of wheel center that may

panying drawing.
