PROVISIONAL SPECIFICATION.
Improved Driving Apparatus for Cycles, Vehicles, and other
Machines.
I, EDWARD BRICE KILLEN, of 38, Victoria Street, Belfast, Tea Dealer, do hereby
declare the nature of this invention to be as follows:
The improved driving apparatus constituting the invention can be applied to
cycles of all kinds, vehicles, and other machines.
The apparatus consists of a suitable chair with suitable back thereon accom-
panied with two suitable driving slides which are properly placed in front of the
chair for the feet of the rider to drive on.
The chair and two driving slides can be made of any suitable size, shape and
substance and when properly made and attached to a cycle they enable the rider
of said machine to utilize his strength in driving 'his machine with great speed
and ease.
These two right and left slides glide or run backwards and forwards side by
side in front of the chair and are placed at a suitable and convenient position from
the chair itself so as to enable the rider who sits thereon with one foot on each
driving slide to move each slide as required.
The enormous power which the rider can get by pressing at the same time on
the chair back and on each slide alternately can be fully taken advantage of by
the rider in driving the cycle or other machine to which this apparatus is properly
attached.
These two gliding slides are connected to the driving axle of the cycle or other
machine by means of cranks and rods or they may be connected in any other
suitable and well known manner.
Improved Driving Apparatus for Cycles, Vehicles, and other
Machines.
I, EDWARD BRICE KILLEN, of 38, Victoria Street, Belfast, Tea Dealer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
The improved driving apparatus constituting the invention can be applied to
excles of all kinds vehicles and other machines.

page_text: The features of novelty constituting the invention are clearly pointed out in the
claims at the end of this specification.
The annexed drawings show, by way of illustration or example, a bicycle con-
structed in accordance with my invention.

Fig. 2 is a plan of the bicycle.
Fig. 3 is an enlarged detail view showing the gear wheels.
Fig. 4 is a back view and Fig. 5 a side view of a pedal.
Fig. 6 is a section and Fig. 7 a part plan showing the slides and guide bars.
Fig. 8 is an end view and Fig. 9 a plan view of one of the ball bearings of a
slide.
Fig. 10 is a diagram showing the action of the gearing.
Fig. 11 is a view showing the mode of driving.
Fig. 12 shows a modification.
Referring to the drawings whereon the same reference letters wherever re-
peated indicate the same or similar parts.
a is the driving wheel. is the steering wheel. c is the driving chain. d is
the ball-head of the frame.. f is the fork. g is a cross stay. h, h¹, are bottom
stays (widened out so as to allow space for the turning of the steering wheel)
running from the axle b¹ direct to the bottom brackets . The bottom brackets i
are connected together by a cross tube j. k, k¹, are the back stays, and, as will be
seen, they run from the brackets i to the axle of the rear wheel. 1, 1, are upright
tubes supporting the seat frame m (see Fig. 1). n is a cross tube connecting the
parts m, m, together. 0, 0, are inclined tubes which run from the bottom
brackets to the front of the seat frame m. is the seat which may be supported
on springs p¹. 7 is a back rest or support. is the pinion on the driving hub.
s is a pillar which springs up from the central tube o2 of the frame. This central
tube runs from the cross stay n to the cross stay j. is a steering pillar having.a
handle bar t¹. 2 are steering wires or chains which connect a cross bar, or
lateral pins, on the pillar with a cross bar, or lateral pins, on, the
pillar of the fork f.. u, u¹, are two slides which are capable of sliding
up and down on guides secured to the inclined tubes o, o¹, o.. These
guides are clearly shown in Fig. 3. The slides u, u', are connected together by
wires or chains u², u³, running over pulleys u. Each slide has a rack w on its
underside. The rack of the slide u is capable of gearing with a segmental wheel x
whilst the rack of the slide u is capable of gearing with a segmental wheel a¹.
Both the wheels, a¹, are carried on a hub a² (Fig. 3) running in ball bearings
on the axle 3. This axle is carried by two inclined stays at extending from the
tubes k, k¹, to the tubes o, o¹. The axle also serves to bind the sides of the
frame together. The chain wheel is carried on the hub 23.
As will be seen at Figs. 6, 7, 8, and 9 the slides u, u¹, are each supported upon
two cross bars y, y', and these cross bars have, at their ends, jaws y in which balls
are fitted as shown clearly at Figs. 8 and 9. The balls which are held in place by
adjustable end pieces y³, y, run upon the guides v.
The pedals may be of any suitable construction but I prefer to make them in
the manner shown at Figs. and 5. One pedal is fitted to the lower end of each
slide. On the drawings the pedals are marked z, z¹. Each pedal is jointed to a
supporting bar 26 having a shoe piece 23 and an upwardly projecting heel piece 23.
The shoe is secured to the slide u or u¹, as the case may be, by means of a bolt z
which passes through a slot cut in the slide. The pedal is preferably so arranged
that the ball of the foot, as shown at Fig. 11, bears against the jointed part of the
pedal. The heel piece is provided in case the rider wishes to use his heel at
certain times when driving. The bolt and slot arrangement allows the pedals to
be adjusted to suit different riders.
The rider, when driving the machine, sits in the position, as shown at Fig. 11,
with his back bearing against the support g. He alternately exerts pressure upon
the pedals z, z¹, so as to drive the slides backwards and forwards on their guides v.

page_text: At each forward or down stroke of the pedal z the rack of the slide u is caused to
act upon the toothed part of the segmental wheel a which, as a consequence, per-
forms a half revolution and drives the machine forward. By the time the slide u
has reached the bottom of its stroke the slide u', owing to the pressure exerted
on the pedal z, is just beginning to act on the toothed part of the segmental
wheel so as to cause it to perform a half revolution and thereby continue the
motion of the machine. At the back or upstroke of each slide the teeth of the
rack run clear of the segmental wheels. The diagram at Fig. 10 shows clearly
the action of the racks and segmental wheels.
The enormous power which the rider can obtain by pressing at the same time
on the support g and on each slide alternately can be fully taken advantage of by
the rider in driving the cycle or other machine or boat to which the apparatus is
attached.
The use of the racks and segmental wheels obviates dead points so that a
continuous drive is given to the machine.
In order that the wheel b may turn from side to side within the fork h, h', it
is provided with an axle 6¹ of the construction set forth in my application No. 24235
dated 20th October 1897.
The slides may, if so desired, be connected to the driving wheel or wheels of the
velocipede or other pedo-motive machine by means of any well known and suit-
able system of gearing such as cranks and connecting rods, cog wheels and chains,
etc. Fig. 12 shows one such arrangement. In this view the slides u, u', operate
the connecting rods 2, 3, which are pinned at 4, 5, to the chain wheel co.
the gear chain. 7, 8, are lugs on the slides u, u¹.
c is
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I consider novel and desire to claim is:
1. A velocipede or other pedo-motive vehicle or machine characterised by slides
(or equivalent) working on an inclined plane and operating gearing for driving
the machine the driver sitting on a seat and pressing against the back thereof
and operating the slides (or equivalent) alternately, substantially as set forth.
2. A velocipede or other pedo-motive vehicle or machine having its driving
mechanism constructed, arranged, and operated, substantially as herein before
described with reference to the drawings annexed.
Dated this 16th day of March 1898.
