We, MARMADUKE MATTHEWS, of the Village of Bracondale in the County of
York, and Province of Ontario, Canada, Artist, ALEXANDER JARDINE, of the
said Village of Bracondale, Manufacturer and AGNES JARDINE, of the said
Village of Bracondale, Wife of the said Alexander Jardine, 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 :-
The object of the invention is to devise a simple and effective bearing for pedal
spindles which requires a minimum amount of thread cutting and will be otherwise
cheaply manufactured, and it consists, essentially, in making the adjusting cone
loose upon the spindle, placing next to it a nut adapted to slide on the spindle but
held from turning by means of a projection engaging with a groove in the spindle,
placing next to the said nut an adjusting nut screwed upon the threaded end of the
spindle, and in placing next to the adjusting out a washer adapted to slide on
the spindle but held from turning by means of a projection engaging with a groove
in the spindle, the whole being constructed in detail substantially as hereinafter
more particularly described and then definitely claimed.
Figure 1, is a longitudinal section of the improved bearing.
Figure 2, is a longitudinal section of a portion of the same taken at right angles
to the section shown in Fig. 1.
Figure 3, is a cross-sectional elevation showing the adjustable conc.
Figure 4, is a similar view showing the adjusting nut.
Figure 5, is a similar view showing the wrenching nut used in screwing the
spindle of the bearing into the crank arm.
Figure 6, is a similar view showing the washer placed between the adjusting
nut and the crank arm.
In the drawings, like letters of reference indicate corresponding parts in the
different figures.
A, is the spindle of the bearing. The outer end of the spindle has a stationary
cone B, formed on or connected thereto. a, is a cylindrical portion of the spindle,
either equal to or of greater diameter than the cone B. The inner end of the
spindle next to this cylindrical portion a, is enlarged as shown at b. A portion of
this enlargement b is threaded, and grooves care cut into the enlargement
preferably extending from the outer edge of the same nearly or quite to the end
of the spindle.
C, is the adjustable cone which is slidable upon the cylindrical portion a of
the spindle and recessed to adapt it to slide over the enlargement b.
D, is a wrenching nut, which is slidable upon the enlargement 6 of the spindle,
but is prevented from turning thereon by being provided with one or more
Next to this wrenching
projections d, which are adapted to fit the grooves c.
nut is located the adjusting nut E, which is threaded to make it adjustable
upon the threaded end of the spindle. Between the adjusting nut and the
crank F, is the washer G, which is slidable upon the spindle, but is held from
turning by being provided with one or more projections e, which are adapted to fit
the grooves c.
Extra washers G, may be added if required.
H, is the casing of the spindle, which is provided with suitable cups to form
ball races with the cones B, and C. The end of the casing is closed by means
of the can I

page_text: When the bearing is connected to the crank ready for use, it appears as in
Fig. 1. If it is desired to adjust the bearing, a wrench is applied to the wrenching
nut D, and the spindle screwed a short distance out of the crank. It then becomes
possible to move the cone E, to adjust the bearing by revolving the adjusting
nut E, which may be either knurled for adjustment by the fingers, or shaped to
receive a wrench. As the wrenching nut slides freely upon the enlargement of the
spindle, the motion of the adjusting nut is conveyed to the cone. Having adjusted
the bearing, the wrench may be again applied to the wrenching nut, and the
spindle tightened into place. The location of the adjusting nut between the two
non-revolvable parts D and G, preventing the disturbance of the adjustment.
As it is desirable to be able to remove all the parts from the spindle without
unscrewing the latter entirely from the crank, the outer parts of the spindle are
made sufficiently small, as previously described, to permit of the cone C, the
wrenching nut D, the adjusting nut E, and the wasber G, being slipped over its
end. By loosening the spindle sufficiently, the balls may be run out of their races
the casing removed and the spindle entirely stripped. By making the adjusting
cone C, slidable upon the spindle and locating a slidable wrenching nut between it
and the adjusting nut E, but a small portion of the spindle need be screw-threaded,
and an important saving in the expense of manufacturing is thus obtained.
The enlargement b, of the spindle, is also a feature of the invention, as if the
spindle were not so enlarged, it would be impossible to arrange the movable parts
of the spindle so that they might be removed over the outer end of the spindle.
A groove cut below the general surface of the spindle could only be made to run
out at the inner end and the nuts and washers would have to be slid on while the
spindle was detached from its crank.
We are aware that slidable washers have been used in connection with a
threaded cone adjustment, but we are not aware of any construction having been
patented, showing the novel features of this device, nor possessing the advantages
of cheapness in manufacture possessed by the invention.
In most pedal bearings the loose parts are generally not more than two in
number and require much internal work in turning and threading. By using a
number of parts the expense of manufacture is greatly decreased, as the adjusting
cone alone requires to be turned and only one part requires threading, the rest
being stamped out. The adjustment might be located at the outer end of the
spindle. As the parts would remain the same, this variation would fall within the
scope of the invention.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed; we declare that what we
claim is :-
1. In a pedal bearing, means for adjusting the bearing and screwing the spindle
into the crank, comprising a cone loose upon the spindle, in combination with a
