Improvements in Bicycles and the like.
I, CADWALADER MALLONY RAYMOND, of Sherman Street, Somerville, in the
County of Middlesex and State of Massachusetts, United States of America,
Manufacturer, do hereby declare the nature of my invention to be as follows:-
-.
My invention relates to certain improvements in bicycles, and particularly those
having pneumatic tires, and the invention consists in constructing the frames of the
machine so that a portion of the same will form an air pump whereby the tire can
be inflated without an independent pump, and also in the means for lubricating the
sprocket wheel or crank shaft, and for forming an oil reservoir for a head light
or lamp.
In constructing bicycles according to my invention the upright post, the back
bone and the rear fork are connected together by a connecting piece having a
hollow central body, and arms, the upright being secured in the body, the back bone
to the arm, and the rear fork on the arms. In the upper portion of the upright is
fitted a washer the internal diameter of which is of a size to just admit the seat
post, both the said washer and the seat post being retained in position by a set
screw that passes through the rear of the connecting piece and the upright.
The lower end of the seat post is fitted with a piston of leather, rubber, or other
suitable material which is free to be forced up and down by pulling and pushing
upon the seat post, the set screw having first been loosened.
At the lower end of the upright is fitted two valves one an induction valve, and
the other an eduction valve, so that the seat post may be operated and air will be
drawn in through the induction valve, and ejected through the eduction valve,
which latter can be connected to either of the admission valves of the tires.
It will be seen that by this arrangement that an air pump is conveniently
embodied in the frame of the bicycle so that should the air escape from the tires
the same can be readily inflated by the person operating the machine by first
connecting said tire with the ejection valve by means of a piece of rubber tube,
then loosening the set screw and then forcing the seat post up and down a few times,
thus the machine is rendered complete in itself, so that the rider has not to carry an
independent air pump with him.
It also consists in an improved means for lubricating the sprocket wheel or crank
shaft, the bottom bracket at the junction of the upright and the lower tub or bar
supporting the front fork is formed of a hollow tube and is at each end provided
with a screw cap and forms the bearings for the sprocket wheel shaft. The space
in the lower tube I fill with a series of disks of felt or other suitable material formed
to fit within said tube. In the upper portion of said tube is formed an oil hole
through which the felt disks may be saturated with oil which will percolate through
the felt and supply the shaft with the required amount of lubricant.
It will be seen that by this construction the sprocket wheel or crank axle will
always be supplied with sufficient lubricant so that it will run easily while at the
same time the lubricant being held in check by the said felt or other suitable
material it cannot run to waste.
The invention further consists in utilizing the back bone as an oil reservoir and
connecting thereto one or two small tubes which are carried to the front of the
steering post and bent upwards, a wick is placed in each of the tubes and carried
down to or near the bottom of the back bone, any suitable shield or covering may
be supported by the ordinary lamp bracket to protect the flame from wind.
Although I described the invention as being particularly applicable to bicycles

page_text: it is obvious that it is equally applicable to all descriptions of such vehicles having
pneumatic tires.

COMPLETE SPECIFICATION.
Improvements in Bicycles and the like.
I, CADWALADER MALLONY RAYMOND, of Sherman Street, Somerville, in the
County of Middlesex and State of Massachusetts, United States of America,
Manufacturer, 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:-
My invention relates to velocipedes more particularly to bicycles or other cycles
having pneumatic tyres.
According to one part of my said invention I so construct the frame of the
machine that a portion thereof will form an air pump for inflating the tyres thereby
avoiding the necessity of carrying an independent pump.
My said invention also comprises means for lubricating the sprocket wheel or
crank shaft, and for forming an oil reservoir for the head light or lamp as herein-
after fully described.
Referring to the accompanying drawings
Figure 1 represents a bicycle embodying my invention a portion of the frame
being shown in section.
Figure 2 is a vertical section through the upright and seat post drawn to an
enlarged scale.
Figure 3 is a horizontal section through the junction of the upright, back bone
and back fork, taken on the line of Figure 2 but drawn to a larger scale than
the said Figure 2.
Figure 4 is a horizontal section through the bottom bracket or bearing for the
sprocket wheel shaft drawn to an enlarged scale.
A represents the front or steering wheel, and B, the rear wheel of a bicycle both
of which are fitted with pneumatic tyres C C, D, is the front fork, E, the back-
bone F, the back fork, and G, the upright.
In bicycles constructed according to my invention the upright post G, the back-
bone E and the rear fork Fare connected together by a connecting piece H having
a hollow central body I and arms 2, 3, 3, the upright G being secured in the body
portion 1 the back bone to the arm 2 and the rear fork to the arms 3, 3. In the
upper portion of the upright G, is fitted a bush J provided with a central hole the
diameter of which is such as to just admit the seat post K, both the said bush and
the seat post being retained in position by a set screw L which passes through the
rear of the connecting piece H and through the top part of the upright G.
The lower end of the seat post K, is fitted with a piston k, of leather, rubber or
other suitable material which is free to be forced up and down by operating upon
the seat post K or the saddle support, the set screw L, having been first loosened.
At the lower end of the upright G is fitted two valves that is to say an induction
valve N, and an eduction valve N' so that when the seat post K is moved up and
down air will be drawn in through the induction valve N and ejected through the
eduction valve N' which latter can be connected to either of the admission
valves ppl of the tyres C C.
It will be seen that by this arrangement an air pump is conveniently embodied
in the frame of the bicycle so that, should the air escape from the tyres, the same
can be readily inflated by first connecting the said tyre with the eduction valve N',
by means of a piece of rubber tube Q, then loosening the set screw L and forcing

page_text: the seat post K up and down a few times. The machine is thus made complete in
itself, so that there is no necessity for the rider to carry an independent air pump
with him.
The improved means for lubricating the sprocket wheel or crank shaft U is
shown in Figure 4 in which R represents the bottom bracket at the junction of the
upright and the lower tube or bars supporting the front fork D. This bracket R
is formed of a hollow tube and is at each end provided with a screw cap R¹ and
forms the bearings for the sprocket wheel shaft. The space in the lower tube S
I fill with a series of discs of felt or other suitable material T, formed to fit within
the said tube S. In the upper portion of said tube is formed an oil holes through
which oil may be introduced to saturate the felt discs T. The oil will percolate
through the felt and supply the shaft U, with the required amount of lubricant.
It will be seen that by this construction the sprocket.wheel or crank axle U,
will always be supplied with sufficient lubricant so that it will run easily while at
the same time the lubricant being held in check by the said felt or other suitable
material it cannot run to waste.
The back bone E is made hollow and is connected with one or more small
tubes e, which are carried to the front of the steering post and bent upwards, a
wick is placed in each of the tubes e, and carried down to or near the bottom of
the hack bone. Any suitable shield or covering may be supported by the ordinary
lamp bracket e¹ to protect the flame from the wind.
Although have shown and described the invention as being applicable to
bicycles, it is obvious that it is equally applicable to other cycles the pump being
of course only required in cycles having pneumatic tyres.
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. In a cycle, the tube G, carrying the seat post K which is provided with a
piston k, in combination with an induction and an eduction valve arranged at the
lower portion of said tube G, substantially as set forth for the purpose specified.
2. The combination with the said tube G and seat post K of the bush J fitting
around the seat post, the screw for retaining the said bush and seat post in place,
and means such as an elastic tube Q for connecting the eduction valve with the
valve of either pneumatic tyre, as set forth.
3. The combination with the tube G of the piece H having arms to which the
back bone and rear fork are secured, substantially as, and for the purpose,
specified.
4. The tubular back bone E adapted to form an oil reservoir, and having one or
more small tubes e attached thereto and carried to the front of the steering post,
substantially as, and for the purpose, set forth.
5. In a cycle frame the means for lubricating the pedal or crank shaft
substantially as herein described.
6. A cycle constructed substantially as described with reference to the drawings.
