PROVISIONAL SPECIFICATION.
A New or Improved Means of Welding Links, Hoops, and other
such like Articles.
I, ALFRED DICKINSON, of Trainway Depot, Darlaston in the County of Stafford
Tramway Manager do hereby declare the nature of my said invention to be as
follows:-
My invention has for its object a new or improved mode of welding links hoops
and other such like articles which I accomplish by electricity in a very expeditious
and effective manner as follows-
I make a holding adjustable jaw or vice so shaped as to receive and hold the
article to be welded whether a chain link or ring or hoop or other such like article
and I bring the ends of the link or other article sufficiently near to each other for
heating. This adjustable holder supports the link at each side and is connected with
an electrical battery. I complete the circuit at the other end by an independent
contact piece whether carbon or metal which is so mounted as to be carried forward to
the two ends to be welded until contact is formed when the ends become heated to
welding temperature. I then break contact by withdrawing the independent
connection and tighten up the jaws by a screw or other arrangement thus bringing
the ends of the heated metal together until the weld is completed. I may of course
apply either horizontal or vertical pressure dies to the link to maintain the proper
shape and these may be worked either by a screw press hammer or other equivalent.
Or the junction may be dressed separately.

COMPLETE SPECIFICATION.
A New or Improved Means of Welding Links, Hoops, and other
such like Articles.
I, ALFRED DICKINSON of the Tramway Depot Darlaston in the County of
Stafford Tramway Manager do hereby declare the nature of my said invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
My invention has for its object a new or improved means of welding links, hoops
and other such like articles which I accomplish by electricity in a very expeditious and
effective manner as follows :-
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto a sheet of drawings upon which I have shewn
diagrams illustrating my new or improved means of welding.
Figure 1 is a diagram shewing the connections for welding a link on both sides.
Figure 2 is a diagram shewing the connections for welding a link on one side.
I make a holding adjustable jaw or vice A so shaped as to receive and hold the
article to be welded whether a chain link or ring or hoop or other such like article H
and I bring the ends h¹ of the link or other article sufficiently near to each other for
heating. This adjustable holder A supports the link at the sides and is connected
by B with an electric battery dynamo or other current producing apparatus D.
I complete the current at the other end by independent contact pieces C whether
carbon or metal which are so mounted as to be carried forward to the two ends ¹² to
be welded until contact is formed when the ends become heated to welding
temperature. I then break contact by withdrawing the independant connections O

the ends of the heated metal together until the weld is completed. I may of course
apply either horizontal or vertical pressure dies to the link to maintain the proper
shape and these may be worked either by a screw press hammer or other equivalent or
the junction may be dressed separately.
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 :-
The new or improved means of welding links, hoops or other such like articles
substantially as herein set-forth and shewn.
Dated this 17th day of June 1890.
