I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors 6, Lord Street, Liverpool and 6 Bank Street,
Manchester both in the County of Lancaster and High Holborn in the County
of Middlesex, Civil 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 consists in an improved machine for welding flanges electrically.
It will be understood from the following description, reference being had to the
accompanying drawings, in which,
Figure 1 is a side elevation of the machine as applied to welding in the head of a
barrel;
Figure 2 is a side elevation with the furnace moved out of position ;
Figure 3 is a plan view of the squeezer ;
Figure 4 is an end view thereof;
Figure 5 is a plan of the work holding clamp;
Figure 6,is a side elevation of the clamp and rotating mechanism;
Figure 8 is a side elevation of the machine as applied to welding a flange with
the work rotating in a horizontal instead of a vertical position, and
Figure 7 is an end view of part of the furnace and squeezer.
A represents the frame of a machine, and B B' represent uprights secured to and
rising from the frame, connected at the top by cross-pieces or slides C C', upon
one of which is fastened a rack D. On base A, in the form shown in Figures ]
to 6, is supported a clamp Q Q', carried on a base q, provided with a central pin l,
rotatable in a boss in base A, and on said pin is fastened a beveled gear R. The
jaw Q of the clamp is provided with a downwardly extending lug n¹, and base 9.is
provided with a similar lug n, the two being connected by a threaded shaft T
provided with a hand wheel U by which jaw Q can be reciprocated or moved to or
from jaw Q. oo' represent guides secured on movable jaw Q, and extending over
jaw to keep the two jaws of the clamp in line. G represents a furnace provided
with carbon holders c c', and in the lower side of the furnace G is formed a slot s,
to receive the flange to be heated.
The furnace G is supported on a threaded shaft f, arranged in the upper part 9
of the furnace, passing up through between guides, and engaging with a nut having
a hand wheel F, by the rotation of which the furnace may be raised or lowered.
a a represent guide rods secured to the furnace, and passing up between the cross
pieces or slides C C', where they are engaged with a guide, to prevent the rotation
of the furnace when the shaft fis rotated. E represents gear wheels mounted on a
shaft journaled in the side of the shaft and provided with a handle Z. These
gear wheels E engage with the rack D and by turning the handle Z thereof the
furnace G may be shifted along the top of the machine. I represents a bracket
carried by the horizontal extension of an arm H rising from base A upon which is
a rack d into which meshes a gear wheel e secured on a shaft r, on the upper end of
the bracket I, whereby said bracket may be shifted horizontally. P represents a
plate adjustably secured to bracket I, and p represents a screw shaft which threads
-

page_text: into the lower end of the plate P and passes through a lug on bracket I, and is
provided at its end with a hand wheel N, by turning which plate P may be raised
or lowered. J and K represent two L-shaped arms, whose horizontal portions pass
through plate P, and whose vertical portions are threaded into and connected with
the right and left hand screw threaded shaft L, provided with a hand wheel M by
which it may be turned so as to move J and K simultaneously in opposite
directions. The inner ends of arms J and K are formed to act as squeezers, arm J
being curved as shown at j, and arm K being straight as shown at k, so that the
parts and may be brought forcibly together, or separated at will, and their
faces are made into proper shape, either plain or curved, to suit the work to
be done.
The operation of this device is as follows:-
Let X represent a cylinder, into which a flanged head is to be welded. This
cylinder X is clamped at its lower end in clamps Q Q', and the flanged head put in
its place on the end of the cylinder; the flange is inserted in slots of the furnace G
and in between squeezers j and k. An arc being now formed in the furnace
between the carbons in the carbon holders c c¹, that portion of the flange within the
furnace becomes heated to a welding heat, and when in that condition is moved
around between the squeezers ; and k by means of the shaft i, journaled in
bearings bb, on frame A, and carrying a bevel wheel R¹ engaging with wheel R,
which shaft i may be turned either by the lever S provided with an ordinary spring
pawl device t, or by any other suitable source of power, until the heated part is
brought between the squeezers j and k, when the end of the cylinder and flange of
the head are squeezed together by said squeezers while another part is being
heated, and as the intense heat of the arc rapidly brings the parts within the
furnace to welding heat, the operation is very rapid, and, indeed, almost con-
tinuous.
As both the furnace and the squeezers are adjustable both vertically and laterally,
they may be readily adjusted to the work, or removed therefrom.
.
The modification of Figure 8 differs only in the position of the rotary clamp, in
which case the article is clamped between two clamps or chucks QQ in a
horizontal instead of a vertical position, this arrangement being specially applicable
to welding together drawn work, such as soda founts, ammonia cylinders, etcetera.
One chuck Q, or both chucks, may be mounted on adjustable spindles, as shown
in Figure 8, the whole, adjusting mechanism being represented by the letters y y',
as there is nothing novel in this adjusting mechanism per se.
Having now particularly described and ascertained the unture of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
1. In an apparatus for welding, the combination of means for rotating the article
to be welded with furnace and apparatus for finishing or compressing the weld,
substantially as shown and described.
2. In an apparatus for welding, the combination of a rotatable clamping device,
a furnace having a slot therein to admit the faces to be welded, with means for
compressing or finishing the weld, substantially as shown and described.
3. In an apparatus for welding, the combination of a rotatable turn table with
adjustable clamp thereon, means for rotating said turn table, and a furnace having
a slot therein to admit the faces to be welded, substantially as shown and
described.
4. In an apparatus for welding, the combination of a rotatable turn table with
an adjustable clamp thereon, means for rotating said turn table, a furnace having a
slot therein, to admit the faces to be welded, with means for compressing or
finishing the weld, substantially as shown and described.
5. In an apparatus for welding, the combination of a movable clamp, means for
opening and closing said clamp, and furnace having a slot therein to admit the
faces to be welded, substantially as shown and described.

8. In an apparatus for welding, the combination of a furnace, a slot therein to
admit the faces to be welded, means for adjusting said furnace to the seam, a
movable clamp, means for opening and closing said clamp with apparatus for
compressing or finishing the weld.
9. In an apparatus for welding, the combination of a furnace, a slot therein to
admit the faces to be welded, a movable clamp, means for opening and closing said
clamp, and adjustable right and left threaded compression jaws for finishing the
weld.
