page_text: JOSHUA FERRINGTON BOLSHAW 38 Balmoral Road Fairfield Liverpool, in the
County of Lancaster Clerk do hereby declare the nature of this invention to be
as follows:-
My invention consists in improvements in that form of cycle lamps which is
hung from the hub of the wheel. In my invention I make the collar which clips
the hub in two parts, jointed and provided with a spring catch which on being
pressed allows the collar to be opened, In order to reduce the frictional or bearing
surface to a minimum, I provide or form two grooves near to each end of the collars
between which I place a packing of india rubber, or other elastic medium which
constitutes the bearing surfaces of the collar. On the outside edges or on the ends
of the collars I form rims which work or fit into grooves provided on the inside of
the hinged cover clip, which I also hinge to the door of the lamp. These rims on
the collar thus keep the lamp in position, The clip is also provided with a spring
catch which on being pressed, allows it to be lifted over the hub and exposes the
collar. The clip being hinged to the door of the lamp can thus be thrown right
over the hub if required, The hinges of the clip are on opposite sides of the hub
at an angle of about 10 degrees from the horizontal line through the axis of the
hub of the cycle.
At the back of the lamp and opposite the oil fountain I provide a shallow and
secondary receptacle for oil the back of which, I form of some flexible metallic
material which on compression by the hand forces the contents in spray through
a small tube arranged in such a way as to project such oil spray on to the wick of
the lamp, so that the lamp wick can always be instantly supplied with hydrocarbon
and be ignited.

County of Lancaster, Clerk do hereby declare the nature of my invention for
IMPROVED CYCLE LAMP and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
My invention has for its particular object improvements in cycle lamps, but
particularly in that form of lamp which is hung from the hub; parts connected
therewith as made according to my invention are shown upon the accompanying
sheet of explanatory drawings. I do not, however, confine myself to the precise
details as herein shown, as they may be varied without departing from the nature
of. my invention.
Figure 1 is a vertical cross section showing lamp with its door partially open.
Figure 2 is an inside elevation of lamp with door open.
Figure 3 is a side elevation of ditto.
Figure 4 is a plan of the top of lamp.
Figure 5 is a sectional plan of same.
Figures 6, 7 and 8 show enlarged details of oil auxiliary feed receptacle.
Figures 9, 10 and 11 show full size details of hub bearing.
Figure 12 shows a plan of oil wick lamp.
Referring to Figures 1, 2, 3, 4 and 5-A is the ordinary catch for fastening
door B, which in the Figure 1 is shown partially open, it is provided with two
joints as shown. The attached projecting piece C, on lifting up the door, presses
the stud of a spring D, in the hub bearing casing E, and releases the catch F,
which permits the door to be thrown sufficiently open to allow the hub bearing
to be removed, or as shown in Figure 3. By means of india rubber rings inserted
in grooves in the hub bearing casing, as shown in Figures 9, 10 and 11, and herein
.further referred to, the hub cone rimmed bearing is made easily adaptable to
different sized axles. The wick lamp G is generally of the ordinary construction
with the exception that I provide a special oil feed cup H, and the lamp wick is
supplied with a circular and improved slot arrangement, shown in detail by
Figure 12. The side and angular placed lens I are provided with special metallic
or other sliding reflectors J, which deflect the luminous rays from back reflector K
at the back of the lamp through the two side lens I.
The sliding reflectors can easily be removed for cleaning when required.
The auxiliary lamp oil feeder L has a flexible back which on being pressed forces
oil up the spray tube M on to the wick of lamp G.
The hub can be lubricated by oil being fed into. holes N, which can be covered
by means of a radial slide P.
The back reflector K slides vertically, and can be lifted by means of the ring R.
One of the side lens I is also movable.
Figures 6, 7 and 8 show a full size detail of auxiliary flexible oil feed receptacle.
The oil spray tube M is arranged to act syphonically, its bore is very small at.the
outlet, or swan neck end, the tube is enlarged at its screwed connection to receptacle
to allow the oil to be fed therein, when tube is unscrewed therefrom,

page_text: The receptacle is provided with a grove S on one side fitted with a pin and a
groove on the other, or a groove on each side thereof, an arrangement which allows
the auxiliary oil feeder to be easily attached and unattached.
When the lamp requires lighting, I simply press the back of oil feed receptacle,
and oil is injected on to the wick, which then light, the oil for sustaining
continuous light being obtained from lamp oil vessel by capillary attraction
through wick of lamp.
The enlarged detail of wick lamp per se-Figure 12, shows the method of
attaching wick-holder T.
The wick-holder T has a stud U, which has a corresponding slot hole V allowing
the wick-holder to be inserted in position, and on turning it, the stud is brought
under the projecting rim and held tight.
The supply of oil is fed into lamp by means of a small cup H, provided with
a hit and miss hole, through which the oil passes into oil holder of lamp.
Figures 9, 10 and 11 show full size detail of jointed hub bearing showing the
spring catch X, and india rubber rings Y and coned rims Z, which work in grooves
formed in inner periphery of hub bearing casing E.
The latter is jointed at one side to the lamp, at the other to the door--the
respective joints, when the door is closed, being at an angle of about 10 degrees
from a horizontal line taken through the axis of the hub of cycle-the joint of the
clip is so arranged as to allow the door of lamp to be thrown sufficiently over the
hub to permit the removal of hub bearing.
The following are some of the advantages derivable from the use of my
invention:-
1. Facility in opening the door and in the accessibility or easy removal of hub
bearing.
2. Improved method in closing hub bearing, and in reducing friction of same,
and also in adaptability of hub bearing to different size of axles.
3. Great improvement in method of igniting lamp wick, which usually becomes
quite dry and free from hydrocarbon, consequently there is the greatest difficulty
in igniting the lamp: in my arrangement I simply press the flexible back of oil
receptacle and a finely divided spray of oil is injected on to the wick, which
instantly ignites on the application of a light.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same may be performed, I claim :-
1. The system of constructing the hub bearing with its lubricating arrangement,
substantially in the manner herein shown and described.
2. The use and form of the auxiliary oil feed with its flexible back, substantially
in the manner and as herein shown and described.
3. The general door opening arrangement with the three joints arranged,
substantially as herein shown and described.
4. The general form and construction of lamp, substantially as herein shown and
described.
