for convenience.
Similar letters refer to similar parts throughout the several views.
The improvements which I particularly wish to describe and claim as new in
this invention are for the construction of the wheels and bearings, the brake,
fixing of handle bars, seat pillars with saddle and the adjustable treadle spindle.
The wheels are attached to a hollow axle with hubs and flanges s with holes
drilled in the flanges and grooves cut on the outside of the said flanges & in which
a spoke with a bent head r is drawn through and lays flush with the outside of
Hange of hub. The spokes 7 are screwed to nipples in the rim of wheels or by any
other means.
The hollow axles are mounted and revolve in bearings, as indicated by dotted
lines in Fig. 5, the said bearings being fixed on to the ends of frame i or front fork h
as in Figs. 1, 5, and 6. The axles are adjusted to the bearings t by means of a circular
cap g with cog teeth, this said cap is secured after adjustment by a click or pall e
with corresponding teeth to fall between the teeth on the circular cap
to prevent
its revolving backwards. The palle is hinged to the bearing t and is rigidly secured
by a flat spring e¹ fixed to the pall as in Figs. 5, and 6. Ball bearings are used as
indicated by dotted lines in Fig. 5.
The brake is connected to an upright bar n the lower end of which is tubular
with a female screw to receive the adjusting wire with a corresponding male screw,
the aforesaid is attached to a chain which passes through a spiral spring m over
pulleys to the, brake handle k. If preferable a bell lever chain or any other
suitable chain, may be used for making the connection between the bar n on the
handle bar e and the brake handle k. The object of the spiral spring m is to force
the brake into its normal position when the brake handle k is released.
For fixing more secure handles, bars, seat pillars, or saddles than has hitherto
been attained; for example:-I cut a groove o or form an indentation in the handle
bar c and insert a cotter or wedge p between the collar or clip d and bolt the same
together as in Figs. 3, and 4, the said cotter preventing the collar or saddle from
revolving or sliding should the bolts become loose.
On each side of the frame i I cut or form a recess and in this said recess I place

page_text: the treadle bearings 7 (which are of the same description as those used for the
other wheels) to carry the treadle spindle. The lower part of the bearings g
termed the block as in Figs. 1 and 7, is provided with a cap pall and spring,
(similar to Fig. 6,) and through this said block a screw which works between
a centre in the frame and, the centre on the set screw u. The object of these
screws is to adjust the treadle spindle when the endless chain expands.
The saddle a is mounted on a pedestal b on the top of frame i
Having now particularly described and ascertained the nature of my said inven-
Ltion, and in what manner the same is to be performed, I declare that what I
'claim, is-
