Improvements in Pedals for Velocipedes.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex 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 improvement has for its object the sealing of the free end of the pedal,
whereby waste of oil from the hub of the pedal and entrance of dust and sand to
the hub of the pedal may be prevented.
In the accompanying drawing,
Figure 1 is a plan of a pedal embodying my improvement.
Figure 2 is a section on line a, b of Figure 1.
A is a portion of the arm or crank supporting the pedal. A' is the pedal axle.
This is applied to the arm A in any suitable manner. B is the hub of the pedal
which surrounds the axle A', and may or may not be separated from the latter by
means of balls B. If such balls are used, the ends of the hub must be provided
with annular oblique faces, 'arranged in opposition to similar oblique faces a',
supported by the axle A', in the well known manner, the face a' at the free end of
the pedal being formed on a nut A2, surrounding the axle A', and engaged thereon
by threads a. Outside the said nut and also surrounding the axle A', may be
arranged the usual washer A³, and the jam-nut A, for binding the nut A³, after
the proper adjustment of the bearing has been made.
The hub B, may be composed of a single piece or it may be composed of a
tubular part 1, and the expanded annular end pieces 2; extending over the ends of
the tube 1, and resting against the shoulders 3, on said tube.
C is the end-plate at the free end of the pedal. C' is the end plate at the end of
the pedal, located next to the arm A. At the free end of the pedal, the end of the
hub has an annular seat C2, directed toward said free end.
C³ is a dome-shaped cup extending over the free end of the axle A', the nuts A*,
and As, and the washer A³, to the end of the hub and resting by its base against
the said annular seat C2. At the base of said dome, there is preferably formed
integral therewith a narrow flange c³ extending outward from said dome parallel
to and in contact with said seat Č². Said flange constitutes an expanded base.
The end-plate C is open at its middle sufficiently to extend over and fit snugly
around the base of the dome C³, and against the flange c³, and bind said dome
against the hub B. Bolts D, extend from the end plates C', through the end
plates C, and bind the latter against said dome. Suitable foot pieces D', are
secured by the bolts D. It will be seen, that said dome becomes a portion of the
rotary part of the pedal, and that by its use the free end of the pedal is entirely
sealed against the escape of oil and against ingress of dust and sand. It is also to
be observed, that the construction described is neat and simple: no threading or
difficult shaping being required to fit the end-pieces 2, to the tube 1, or to fit the
dome C2, and the end-plate C, to the end of the hub. The end-pieces 2, may be
formed by drop forging or ordinary lathe work, and the dome C³, may be made by
drop forging, stamping, spinning or turning. The end-plates C, may be formed by
drop forging or stamping.
In re-adjusting the bearing of the pedal, the end-plate C, and the dome C³, are
removed.

page_text: Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed as communicated to
me by my foreign correspondents 1 declare that what I claim is:-
1. In a pedal, the combination with an axle A', of a hollow hub B, surrounding
said axle, a nut surrounding the free end of said axle, a dome C³, surrounding said
nut and the free end of said axle and resting against a suitable annular seat on
said hub, and an end-plate surrounding said dome and binding the latter to said
seat, substantially as shown and described.
2. In a pedal, the combination of the axle A', of a hollow hub surrounding said
axle, an adjusting nut surrounding the free end of said axle, an annular seat on the
free end of said hub, a dome surrounding the free end of said axle and said nut and
having an expanded base resting upon said seat, an end plate surrounding said
dome and resting against said expanded base, substantially as shown and described.
3. In a pedal, the combination with the axle A', and a hub consisting of a
tubular part 1, and end-pieces 2, of a nut A2, a dome C³, having an expanded base,
end-plate C, extending over said dome and resting against said base, end-plate C¹,
located at the end of the pedal to which the pedal arm is to be attached, and
suitable connections as bolts D, extending from the end plate C¹, to the end
plate C, substantially as shown and described.
4. In a pedal, the combination with the axle A¹, and a hub consisting of a
tubular part 1, and end pieces 2, having oblique faces 6', of balls B¹, a nut A³, a
dome C, having an expanded base, end-plate C¹ extending over said dome and
resting against said base, end-plate C¹ located at the end of the pedal to which the
pedal arm is to be attached, and suitable connections as bolts D, extending from
the end-plate C¹, to the end-plate C, substantially as shown and described.
