COMPLETE SPECIFICATION.
Improvements in Pneumatic Saddles for Velocipedes or Cycles.
I JOHN CARROLL of 53 Leeson Street in the City of Belfast and County of
Antrim in Ireland Flax Sorter 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 improvements in the saddles of velocipedes or cycles
for which 1 obtained Letters Patent dated 13th April No. 6259 of the year 1891
to my Complete Specification of which improvements I beg leave to refer.
My present improvements are applicable for the better ventilation and simpler
construction of the saddle the subject of my said Letters Patent and for these
purposes instead of perforating the pear-shaped saddle plate and employing a tube
or funnel having one extremity attached to an orifice in the top of the cap or hood
of the saddle and passing its other extremity through the perforation in the plate
I form an orifice in the bow or peak of the cap or hood and attach a tube of
impervious material to it and to the orifice in the top of the cap or hood so that
the air is caught in the bow or peak orifice and conveyed by the tube to and
discharged at and from the top orifice.
The orifices are formed by internal flanges moulded on and with the cap or hood
of the saddle but the air tube may more conveniently be moulded separately from
the cap or hood and affixed at each extremity to one or other of the flanges
therein by means of rubber cement or other adhesive matter such as is commonly
used for that purpose.
The mouths or extremities of the air tube may be trumpet or bell shaped. if
necessary to fit over or into the flange orifice.
I may employ air tubes detached except at the orifices from the cap or hood of
the saddle or I may attach them to it throughout and I may increase the number
of air inlets and outlets or of either of these and of the air tubes and I may
bifurcate the air tubes at either end to suit a greater number of orifices in the bow
or peak than in the top of the cap or hood or the reverse as the case may be.
But I do not confine myself to inlet orifices at the bow or peak only as I may
employ some at the sides of the cap or hood and in like manner I may employ
outlet orifices elsewhere than in the top of the cap or hood.
I introduce into the air tube according to a common practice spiral wire which
will prevent it from collapsing under pressure of the inflation of the saddle and
from thus stopping the free passage of the ventilating current.
I prefer to fasten the cap or hood to the saddle plate on its upper or inner side
by employing a bulb edged and pear-shaped frame placed within the cap or hood
on the top of its flange and provided with snugs or lugs having bolts or screws
attached to them which pass through corresponding perforations in the flange of
the cap or hood and in the saddle plate and force the flange into a groove in the
saddle plate made to receive the bulb edge of the frame so as to secure an airtight
joint.
And in order that my said invention may be more fully understood I shall now
proceed to refer to the drawings on the sheet hereunto annexed the same letters
of reference indicating the same or corresponding parts of my improved ventilating
appliances throughout all the figures.
Fig. I is a top view of a pneumatic saddle shewing two perforations in the top
of the cap or hood and by dotted lines a bifurcated air tube within it leading to
those perforations from an inlet in the bow or peak of the saddle.
Fig. II is a longitudinal sectional elevation of the same showing the air tube or
tubes within and independent of the cap or hood also the saddle plate and the

page_text: internal frame with bolts or screws holding the flange of the cap or hood to the
saddle plate.
Fig. 111 is a front elevation of the same showing the inlet to the air tube or
tubes and
Fig. IV is an enlarged detail of the air tight joint between the frame and the
saddle plate.
a a are the perforations in the top of the cap or hood bbb are the air tubes
within it and is the inlet to the air tubed is the bulb edged and pear-shaped
frame and ee are the bolts or screws which pass through corresponding perfora-
tions in the flange f of the cap or hood 9 and in the saddle plate h and thereby
form an airtight joint.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I would have it to be
understood that I do not claim as of my invention nor the exclusive use of a
pneumatic saddle (save as claimed and set forth in the Specification referred to in
my said Letters Patent of 13th April 1891) except when the same is constructed
specially and arranged or employed as herein described nor do I claim the use of
saddle plates, frames, bolts, caps or hoods tubes or spiral wire linings nor of any
of the separate mechanical parts which form the apparatus used by me but I declare
that what I claim is-
hereinbefore
1. The manufacture and use for cycling purposes of a pneumatic saddle arranged
with air tubes substantially in the manner and for the purposes
described and illustrated by the drawings hereunto annexed.
2. The combination and arrangement of parts constituting my improved pneumatic
saddle constructed and employed substantially in the manner and for the purposes
hereinbefore described and illustrated by the drawings hereunto annexed.
Dated this 7th day of January 1893.
