PROVISIONAL SPECIFICATION.
Improvements in Fittings and Bearings of Cycles and other
Vehicles.
We ALBERT ROBERT WICKENS of 49 Grosvenor Park, Tunbridge Wells
Engineer, and CARL MIOHAELSON, Meadow Hill Road, Tunbridge Wells, Engineer
do hereby declare the nature of this invention to be as follows:-
This invention relates to the fittings of cycles and velocipedes known as the cranks
and crank axles. The object of the invention is to provide a new means of attaching
cranks to their axles and an improved method of fitting the axles to their bearings in
the frame of the machine. For this purpose a hollow or tubular axle is used and is
provided with slotted ends across the diameter at both ends, the eyes of the cranks
also carry slots to correspond with those in the axle.
When the cranks are in position on the axle, a bolt carrying a snug or snugs to fit
the slots in one crank and one end of the axle, is inserted through the eyes of the
cranks and the axle; to fasten this, a nut is screwed on against a washer which
carries also a snug or snugs to fit the other crank and the other end of the axle, the whole
being secured by a lock nut or other suitable means. The axle is provided near its
centre with two discs each bolding balls which run in two divided ball races, one part
of each of which forms a screwed adjustment cap and the other part a screwed cup
inserted between the discs.

COME LEIE SPECIFICATION,
Improvements in Fittings and Bearings of Oycles and other
Vehicles.
We, ALBERT ROBERT WIOKENS, of 49 Grosvenor Park and CARL MICHAELSON
Meadow Hill Road, both Engineers of Tunbridge Wells, 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 :-
This invention relates to the fittings of cycles and velocipedes known as the crank
and crank axles and their attachments.
The object of the invention is to provide a new and more efficient means of
attaching cranks to their axles and pedal pins to their cranks in an easier and quicker
way than has hitherto been done.
For this purpose a hollow or tubular axle is used and is provided with a slot across
the diameter of each of its ends.
The eyes of the cranks also carry slots to correspond with the slots in the axle.
When the cranks are in position on the axle à pin or bolt of suitable length and
carrying one or more lugs to fit the slots in the crank and in one end of the axle is
inserted through the eyes of the cranks and through the axle. To secure this bolt in
position a washer also carrying one or more lugs to fit the other crank and the other
end of the axle is placed upon the bolt and held in position by a nut or nuts which
are sorewed upon the bolt and up against the washer,

page_text: If preferred a pin or bolt of ordinary description can be used instead of one fitted
with lugs, in which case a washer carrying the lugs must be used at each end of the
axle, the bolt being squared or keyed into one of the said washers.
For light or heavy work the slots in the axle and in the crank may vary in number
but should be the same in each, and the number of lugs either upon the bolt and
washer or upon the washers, may also vary accordingly.
We will now describe the invention with reference to the accompanying drawings
in which:
Fig. 1 shows a side elevation of the hollow axle provided with slots at each end.
Fig. 2 shows a transverse section of Fig. 1 on line 1-2.
Fig. 3 shows a longitudinal section of a complete axle, fitted up on our system with
one crank shown in place.
Fig. 4 shows a transverse section of Fig. 3 on line 3—4 looking in direction of
the arrow.
Fig. 5 shows a perspective view of one end of a crank, the eye of which is shown
prepared to receive the lugs on the washer or bolt head.
Fig. 6 shows an elevation of a modified form of our invention wherein an ordinary
bolt and nut is employed, two washers with lugs being used instead of the lug being
cast on the bolt head at one end.
Referring to Figs. 1 to 5 :-
a is the hollow axle provided with slots a' at each end.
may be used.
One, two or more slots
bis the fastening bolt or pin passing, through axle a. This bolt or pin at its head,
is provided with one or more lugs c, and at its opposite end is screwed to receive at
nut cand a washer provided with one or more lugs.
The method of fitting up our invention is as follows:-
The eyes of the two cranks d are fitted on to the axle, in position, with the slots in
each corresponding. The bolt is then passed through the cranks and hollow axle, the
lugs c, on the bolt and washer being placed into the corresponding slots. The whole
is then made secure by the nut c¹.
Referring to Fig. 6, e is an ordinary bolt or pin, screwed at one end, and same
receives at either end a washer f, provided with a lag, the crank and axle being
fitted on as previously explained.
This is a less costly method of fitting than that first described.
In the case of pedal pins the pedal pin is made hollow resembling tube a Fig. 1
and is provided with slots resembling a' at one end, and these engage with lugs
projecting from a bolt similar to 6 passing through the hollow pedal pin, and these
lugs in their turn engage with recesses in the end of the crank arm in the manner
shown in Fig. 5. Or a washer similar to f with slots similar to f' may be used in
place of lugs on the bolt head.
Having now. particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim.is:-
1. In a crank axle or for like purposes the combination of a bolt and washer
or of a bolt with two washers, and a hollow axle, such bolts and washers having
lugs which engage with slots in the ends of said axle, as herein described and set
forth.
2. In a pedal pin or for like purposes the combination of lugs on said pin
engaging with slots in the crank eye, or of a separate washer keyed to said pin
and with lugs formed thereon to engage with said slots as herein described and set
forth.
