I, FREDERICK ARTHUR PYKE, of 115, Bright Terrace, Gibralter: Street, Bolton, in
the County of Lancaster, Clerk, do hereby declare the nature of my said invention to
be as follows:
This invention consists of improvements in or relating to cycles and other road
vehicles, such as, motor cars, carriages, cabs, carts, and the like, and has for its
object that of providing efficient lubricating arrangements and means for ascertaining
the amount of lubricant contained therein.
Between the metal or metallic ends of the hub is disposed a metallic cylinder
provided with a sight hole covered with glass or other suitable transparent or semi-
transparent material or substance in which metallic cylinder oil or other lubricant is
located. The hub is provided with a cup for charging the same with oil or lubricant.
This cup is provided with a screw cap or cover to allow of the same being charged
or emptied of lubricant when desired or necessary. The sight hole covered with glass
before mentioned is to enable of the amount of lubricant contained in the metallic
cylinder being ascertained. If desired the caps or covers of the ball bearings may be
of glass to allow of the action of the balls forming the ball bearings being ascertained
at will. This invention is equally applicable to the pedal centres, bottom bracket in
which the crank axle revolves, and other parts requiring lubrication. The oil or
lubricating chamber may be charged by means of an oil-hole cut or drilled in
the centre spindle, or by means of an indent.

I, FREDERICK ARTHUR PYKE, late of 115, Bright Terrace, Gibralter Street, but now
of 13, Abbey Grove, Bolton, in the County of Lancaster, Clerk, 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:-
.
That is to say It consists of improvements in or relating to cycle and other road
vehicles such as motor cars, carriages and the like, and has for its object the produc-
tion of efficient lubricating devices and means for ascertaining the amount of lubricant
contained therein.
In the accompanying sheets of drawings which are illustrative of my invention :-
Fig. 1 is a sectional elevation of the hub of a velocipede's driving wheel, showing it
es mounted on its spindle.

page_text: Fig. 2 is a similar view to Fig. 1 but shows a modification hereinafter explained.
Fig. 3 is a sectional end elevation of the hub shown by Fig. 2.
Fig. 4, is a sectional view of another form of hub hereinafter described.
Fig. 5 is a sectional side elevation of a hub constructed in accordance with another
part of my invention.
Fig. shows a hub of a modified form as compared with those shown by
Figs. 2 and 3.
Figs. 7 and 8 are drawings in detail hereinafter explained.
Similar letters and figures of reference indicate similar parts throughout the several
views.
In carrying my invention into effect I form an opening a in the metal hub b
wherein I can secure the transparent bulb or cup c (which may be of glass or other
suitable substance wherein transparency and other functional qualifications desired of
it are secured) said position of the bulb c preferably being diametrically opposite to
the feeding aperture din said hub.
On the lubricant being supplied through the aperture d it enters the hub b and flows
over the bearing bushes e to lubricate the antifriction balls e¹ as desired, while when
or by reason of the hub being used, or for other causes, the lubricant in said hub has
been exhausted or fallen below the edges e² of the bushes e (thus it is brought too low
to flow over these edges to perform its lubricating functions) in which case it will
have fallen below the inwardly projecting neck c¹ of the bulb c, when said hub b is
turned so that the bulb c is brought to the underside or beneath same, it will be seen
on the lubricant failing to enter the said bulb c that more of it must be supplied
through the opening d. Or further, it will be seen whether by the discoloration of
said lubricant it is desirable to remove it and add a fresh supply.
In the formation of the hub shown by Fig. 1, when my improved lubricating
devices are used in connection therewith, I employ a cap f which screws and fits
tightly thereon and close up to the shoulder fl on the spindle's cone g by which
means the lubricant is appropriately retained within the hub b as desired."
Instead of the bulb or cup c being used, a metal neck or tube h (see Figs. 2 and 3)
may be mounted on the hub b, and in this tube lateral openings are formed so that
on a glass tube & being placed and tightly fit within the tube h where it is further
secured by a tightly fitting cap h² the flowing of the lubricant into it will afford the
indications desired and as explained with reference to Fig. 1, the cap fin this present
form of hub being constructed to suit and as shown by Fig. 2.
On account of the orifice that the tube h presents to the interior of the hub b being
somewhat large it may be covered by the disc 3 while apertures or openings h may
be made laterally in the tube h at the proper and desired distance within said hub b
to enable the flow of the lubricant into the tube k as described.
Of course I am aware that the shapes and forms of the bulbs or cups c and the
tubes h and may be varied and carried into effect in many ways to suit the taste or
desires of the user or producer and that without departing from the nature of my
invention.
Again instead of the cups c or tubes & being used certain parts 61 of the hub b may
be cut away as shown by Fig. 6, and a transparent or semi-transparent tube m (of
glass, celluloid or other like substance) may be fitted into this hub b, by which means
the amount of lubricant contained by the hub could easily be seen. The joints of
this tube mas also all those at the several parts where the cups c and tubes k as well
as the several caps f to fare required to be sealed or rendered tight to prevent
escape of the lubricant, any of the well known packing substances for producing
this class of joint may be employed as will be well understood.
As to the other part of my invention the caps f³ (see Fig. 4) may be made of a
transparent substance as glass, celluloid or the like, in order that the anti-friction
balls e¹ may be seen and their actions ascertained or examined whenever desired or
necessary.
Or instead of the whole cap f³ being transparent the annular part f³ (see Fig. 5) may
alone be the transparent part, while the screwed hoop f* and that at 5 may be of

page_text: metal. The joint between the spindle gi and the annular piece is preferably
formed by a felt, leather or like facing material being used.
Or again the transparent part fo may be employed as shown by Fig. 7 in which case
the cap is modified in form to suit it, or the cap fo may be formed as shown by Fig. 8
and this form affords better facilities for examining the parts within it.
The several drawings referred to in the above description only illustrate the hub of a
velocipede's wheel, however as the differently formed hubs of other vehicles' wheels, as
those of motor cars, cabs, carriages and the like, as well as the hubs on the pedals of
velocipedes, and the crank brackets of same are all of the same nature so far as
regards the application thereto of my said invention, it will be readily understood how
same may be carried into effect in each of said cases from the description above, hence
further illustrations are not necessary.
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 :-
1. The improved devices whereby the lubricating of the parts herein referred to
may be examined or ascertained substantially as herein specified.
2. In the construction or production of the hubs of vehicles' wheels or in that of
those for similar purposes, the employment of transparent or semi-transparent
coverings for openings which allow the condition or quantity of, lubricant to be
examined or ascertained substantially as herein set forth and described.
3. The improved construction or formation of a hub substantially as herein set forth
and as described by reference to Figs. 1, 2 and 3.
4. The improved construction or formation of a hub substantially as herein set forth
and as described by reference to Fig. 6.
5. In combination with a hub having antifriction ball bearings, a transparent cap
or cover whereby the condition of said bearings may be examined or ascertained
substantially as herein specified.
