PROVISIONAL SPECIFICATION.
An Improved Cap to Protect the Edges of Cycle Lugs during
Transit.
I ROBERT JOHN ALPE of 292 Burbury Street Birmingham in the County of
Warwick Engineer do hereby declare the nature of this invention to be as
follows:-
In place of the ordinary wood plug which is usually used I form a cap or ferrule
of brazing metal which I place over the thin edge of cycle lugs and their like thus
protecting the said edge from damage during transit,
This cap at the same time supplys metal to braze the joint where the lug fits on
the tube.
I may drive my cap over the outside of lugs or inside as may be found most
convenient.

An Improved Cap to Protect the Edges of Cycle Lugs during
Transit.
I ROBERT JOHN ALPE of 292 Burbury Street Birmingham Engineer do
hereby declare the nature of this invention and in what manner the same 18
to be performed, to be particularly described and ascertained in and by the
following statement :-
My invention has for its object an improved cap to protect the edges of cycle
lugs during transit and obviates the necessity of inserting a wood plug within the
lug which has hitherto been done to effect the same purpose, which is, to prevent
any indentation or damage to those edges of the lugs which have to be brazed to
the tube to form the frame. These caps are formed of brazing metal a sufficient
quantity of which is contained in each cap to braze the joint of that end of the lug
which it covers thus economizing metal while the stamping up of the cap is very
readily effected and the cap can be more easily attached and detached from the lug
than the before mentioned wood plugs.
In order that my invention may be clearly understood and more easily carried
into practise I have appended hereunto a sheet of drawings upon which I have fully
illustrated the nature of my said improvements.
Figure 1 is a view of a cycle lug with one of my protecting caps attached
thereto.
Figure 2 is a section through Figure 1.
Figure 3 is a view of the cap detached.
Figure 4 is a section through the edge of part of a lug shewing a modification.
Figure 5 is a similar view to Figure 4 but shewing a further modification.
In carrying my invention into effect I manufacture my cap A of brazing metal

page_text: which has been previously rolled into sheets and stamped or otherwise formed into
the shape required these caps A are placed upon the thin edge 61 of the lug which
edge requires to be kept true and free from indents for the purpose of attachment
by brazing to the tubes forming the frame of the machine. The cap being formed
of brazing metal thus supplies sufficient metal for brazing the joint between the
particular end of the lug which it covers and the tube to which it is attached.
The caps A may be provided with one two three or more slots so as to enable them
to the more readily fit any slight variation in the end of the lug. In place of
covering the outside of the lug with my cap I may so form it as to fit inside the
lug as shewn at A2 Figure 4 if so desired or I may use only a ferrule A³ Figure 5
with nearly the same effect while the cap or ferrule could be varied in shape to
accommodate the various forms of lugs to be met with whether for cycles or
the like.
Although I prefer to form my caps of such metal as herein described yet the
caps may be formed of metal other than used for brazing as for instance steel.
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 1
claim is
1. An improved cap or ferrule A for protecting the edges of cycle lugs during
transit substantially as herein set forth and shewn upon the accompanying
drawing.
2nd. The improved cap or ferrule for protecting the edges of cycle lugs formed
of brazing metal to be used in brazing the joint substantially as herein set forth.
