both of Atlas Works, Halifax, in the County of York do hereby declare the nature
of the said invention for "IMPROVEMENTS IN APPARATUS EMPLOYED DURING THE
HEATING AND WELDING OF HOT WATER CIRCULATING AND OTHER LIKE BOILERS
AND CISTERNS to be as follows:-
"
This invention relates to the manufacture of welded boilers, and the object of
the invention is to dispense with the massive pulley blocks cranes lovers and
overhead lifting gear hitherto used by the construction of improved apparatus,
designed to facilitate the introduction, of parts of a boiler to, and removal from,
the "fire," during the operations of heating, and welding-with less labor in less
time and with less risk of accident to the operatives.
During the heating, and welding, the ends of saddle, square, rectangular, or other
than cylindrical form of boilers, we employ a trolly, mounted upon rails, and
having two platforms, one above the other-The lower platform is carried by tho
trolly wheels, and the upper platform is supported by uprights, capable of being
raised and lowered-On the upper platform is a turntable, on which are a number
of anti friction pulleys, or wheels, the latter support an iron cylinder or casing
within which, the boiler under operation is placed and secured so that its end, or
ends, protrude beyond the end or ends of the said cylinder-The cylinder is provided
with a counterbalance weight for balancing the weight of the boiler.
The apparatus operates as follows:
The cylinder or case, containing the boiler, to be heated, and welded, is placed
on the antifriction wheels, of the turntable, the whole may by the trolly and rails,
be advanced to, and withdrawn from, the "fire"-the upper platform, turntable,
cylinder, or case, and boiler, can be raised or lowered, so as to adjust the part of the
boiler to be heated, to the height of the fire, by means of worm and bevel gear,
carried by the lower platform, the gear operate a cross shaft on the ends of which
are pinion wheels, gearing with racks, formed on the uprights which support the
higher platform, the turntable is movable on a central pin, or pivot which provides
for lateral radial motion of platform, and boiler, whilst the antifriction wheels and
cylinder, provide a ready means by which the boiler can be rotated, or moved to

page_text: any degree of a circle, there is thus provided apparatus, which enables, any part
of the end of a boiler, of any regular, or irregular shape or configuration, to be
accurately adjusted to the fire, and as each length is heated, and welded, the
succeeding length, is with expedition, adjusted or set, in true position for the
next heat.
As an alternative plan, the trolly and rails may be raised, and lowered the rails
being secured to a platform, or turntable, the supporting pillar of which is screwed
or chased, so as to work in a thread, formed in the eye, of the boss of a bevel wheel,
carried on a supporting stand and collar, the bevel wheel referred to, being actuated
by another like wheel, gearing therewith, so as to raise and lower the platform and
rails as required.
For purpose of bringing the legs or continuous length of saddle and other like
boilers into position for being applied to the fire and being heated we arrange the
carriage or trolly to move sideways or transversely alongside the fires hearth-
This carriage is provided with bearings to support the boiler at each end and such
bearings are arranged so that they can be readily adjusted endwise or longitudinally
as well as vertically and laterally (nearer to and further from the fire) so as to
adapt them to the various lengths and heights of boilers to be welded-The boiler
itself is secured to clamps in the ordinary way and the shaft or axis of such clamps
resting in the said bearings the boiler can be readily turned round on and off the
fire as required for each succeeding weld.

DIMUITICATION.
We JOHN COLLIER, Boiler Maker, and ENOCH BINNS, Foreman Boiler Maker,
both of Atlas Works, Halifax, in the County of York do hereby declare the nature
of the said invention for "IMPROVEMENTS IN APPARATUS EMPLOYED DURING THE
HEATING AND WELDING OF HOT WATER CIRCULATING AND OTHER LIKE BOILERS
AND CISTERNS" and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention consists of improved apparatus designed to facilitate the
introduction of parts of a boiler to, and removal from, the "fire" during the
operations of heating and welding, with less labor in less time and with less risk
of accident to the operativos.
Such being the nature and object of the said invention the following is a completo
description of same, reference being had to the accompanying drawings forming a
part of this specification in which :-
Fig. 1 is an end elevation.
:-
Fig. 2 is a plan with cylindrical shell and boiler removed.
Fig. 3 is a side elevation.
Fig. 4 is clevation of carriage for placing the legs or continuous length of boiler
in fire for heating.
Fig. 5 is a plan of Fig 4.
During the heating, and welding the ends of saddle, square, rectangular, or other
than cylindrical form of boilers according to this invention we employ a trolly 1,
mounted upon rails and having two platforms, one above the other-The table 1
is carried by the trolly wheels, and the lower platform 2 is supported by uprights 3,
capable of being raised and lowered-On the platform 2 is an upper platform or
turntable 4, on which are a number of antifriction pulleys or wheels 5, the latter
support an iron cylinder or casing 6, within which, the boiler G under operation is
placed and secured by moving and closing the parts or cylindrical shells 6. 6. upon
the boiler under operation, 71 72 are bolts and holes for securing and adjusting
the parts 6. 6. to grasp various sizes of boiler and so that the boiler end or ends,
protrude beyond the end or ends of the said cylinder-The cylinder is provided
with a counterbalance weight Gb for balancing the weight of the boiler.
The apparatus operates as follows:-
The cylinder, or case 6. coutaining the boiler, to be heated, and welded, is placed
on the antifriction wheels 5, of the turntable 4 the whole may by the trolly 1,
upon the rails 7, be advanced to, and withdrawn from, the "fire" the platform,
turntable 4, and cylinder or case 6, and boiler, can be raised or lowered so as to
adjust the part of the boiler to be heated, to the height of the fire, by means of
winch handle 8 worm 9 worm wheel 10 and bevel gear 11. 12 carried by the table
or trolly 1-The gear operate a cross shaft 13, on the ends of which are pinion
wheels 14, gearing with racks 15, formed on the uprights 3, which support the

page_text: platform 2, the turntable 4 is movable on a central pin or pivot 16, thus providing
lateral and radial motion of platform and boiler, whilst the antifriction wheels 5,
and cylinder 0, provide a ready means by which the boiler can be rotated or moved
to any degree of a circlo-The antifriction wheels 5 can be adjusted in thoir
brackets 5 nearer to or further from each other to suit varying sizes of boiler and
cylinder There is thus provided apparatus which enables, any part of the end of
a boiler, of any regular or irregular shape or configuration to be accurately adjusted
to the fire, and as cach length is heated and welded, the succeeding length, is with
expedition, adjusted, or set, in true position for the next heat.
For purpose of bringing the "legs" or continuous length of saddle and other like
boilers into position for being applied to the fire and being beated we arrange the
carriage or trolly to move sideways or transversely alongside the fire hearth-Tho
carriage is provided with fork bearings 18 to support the boiler at each end and
such bearings are arranged so that they can be readily adjusted endwise or
longitudinally as well as vertically by the holes and bolts 19 and laterally by
means of the pulleys 20. 21 which run on the edges of the rail 22, (nearer to and
further from the fire) so as to adapt them to the various lengths and heights of
boilers to be welded-The boiler itself is secured to clamps in the ordinary way
and the shaft or axis of such clamps resting in the said bearings 18 the boiler can
be readily turned round on and off the fire as required for each succeeding weld.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what
we claim is
1. The improved apparatus comprising the cylinder 6 supported and capable of
being moved or rotated upon anti friction rollers 5. 5. which are carried by
turntable 4, mounted upon a platform the latter having vertical and longitudinal
motions as herein described and illustrated by drawings.
