Complete Specification Left, 13th Nov., 1894-Accepted, 15th Dec., 1894
I, OLAF PIHLFELDT, of 29 Golden Hillock Road, Small Heath, in the City of
Birmingham, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in cycle pedals, and has for its object, the..
securing or connecting of the end plates to the hub or tubular middle member
wherethrough the spindle passes.
In carrying out my improvements, the hub or middle member consists of a hollow
tubular waist part, with end cases or hollow heads made solid with it, whose
peripheries are slightly coned, with the taper rising from front to back, and with
the open mouths or ends sunken or formed into ball races.
Each of the end plates have bossed eyes or socketed middle parts, with the same
inside coned and adapted to take and fit tightly upon the coned heads or cases of
the hub.
Thus, the end plates, which have bossed eyed or inside cone-socketed middle
parts, are fitted to the hollow heads or case ends of the tubular middle member or
hub, by the said coned sockets taking upon the outside-coned peripheries of the
said heads, and are there affixed by a closing process, or by other means.

Improvements in Cycle Pedals.
I, OLAF PIHLFELDT, of 29 Golden Hillock Road, Small Heath, in the City of
Birmingham, Mechanical 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 :-
-
My invention relates to improvements in cycle pedals, and has for its object, the
securing or connecting of the end plates or end parts to the hub or tubular middle
member wherethrough the spindle passes.
According to my improvements, the hub or middle member consists of a hollow
tubular waist part, with end cases or hollow heads made solid with it, and having
their peripheries slightly coned, with the taper rising from front to back, and with
the open mouths or ends sunken and formed into ball races.
Each of the end plates or end parts have bossed eyes or socketed middle parts,
which are inside coned and adapted to take and fit tightly upon the coned heads or
cases of the hub..
Thus, the end plates, which have bossed eyed or inside cone-socketed middle
parts, are fitted to the hollow heads or case ends of the tubular middle member or
hub, by the said coned sockets taking upon the outside-coned peripheries of the said.
heads, and being there affixed by the forcing of the socket part over the head part,
or by closing the metal at the end of the one slightly over the metal at the end of
the other.

page_text: Figure 1 of the accompanying drawing represents a horizontal section, partly in
elevation, of a rat-trap cycle pedal constructed according to my invention.
Figure 2 represents an end view of the pedal Figure I, showing the left hand end
plate or end part of the said pedal and also the bossed eye or inside coned socket of
it, wherein a coned head or case at one end of the tubular middle member takes.
Figure 3 represents a cross section of the pedal upon the dotted line -
Figure 1, looking towards the end plate.
Figure 4 represents, in section and in elevation, the whole of the component parts
of the said pedal separated.
Figure 5 represents an elevation of the hub or tubular middle member.
Figure 6 represents my invention applied to a rubber tread pedal.
!
The same letters of reference indicate corresponding parts in Figures 1 to 5 of
the drawing.
a are the end plates or end parts, having bossed eyes or inside coned sockets a',
which take upon like outside coned heads or hollow cases b', of a hub or tubular
middle member b, having a contracted waist 62, which said end plates are united,
braced or tied together, after their inside coned sockets have been forced upon the
outside coned heads of the hub by pressure, by rat-trap side plates c, rivetted or
otherwise connected at c², to the ends a², of the plates a.
The spindle, ball bearings and other parts of the pedal are of the ordinary
construction and arrangement.
In the rubber pedal, Figure 6, the end plates a are braced together by bolts or
rods c, passing through the axes of rubber treads d, and being affixed by nuts e,
taking upon the screwed ends of the said rods, or the ends of the said rods may be
rivetted.
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
-
In cycle pedals, securing or affixing the end plates or end parts to the ends of
the hub or tubular middle member, by inside cone sockets of the one part fitting
upon outside coned ends or heads of the other part, substantially as described and
set forth.
