in the County of Essex, for the Invention of "IMPROVEMENTS IN BICYCLES,

Sealed the 5th August 1879, and dated the 15th February 1879.
Sealed the 5th August 1879, and dated the 15th February 1879.
PROVISIONAL SPECIFICATION left by the said Josiah Puntis and Thomas,
Puntis at the Office of the Commissioners of Patents on the 15th February"
1879.
JOSIAH PUNTIS and THOMAS PUNTIS, both of Upton Park, in the County of.
Essex. "IMPROVEMENTS IN BICYCLES, TRICYCLES, AND OTHER VELOCIPEDES OR
WHEELED VEHICLES PROPELLED BY MANUAL LABOUR."
This Invention relates to improved apparatus to be used solely as an adjunct or
an additional accessory in the propelling of bicycles, tricycles, and other velocipedes
or wheeled vehicles propelled by manual labour.
This improved apparatus is to be fitted to bicycles, tricycles, or other velocipedes
for accellerating speed, lessening the strain of manual labour, overcoming the
resistance of wind, and for imparting steadiness and elegance to the machine.
The method of carrying our Invention into practice consists, primarily, in the
adaptation, use, and application of the fly wheel or weighted arms or rods serving
as an equivalent for the fly wheel attached to the axle of velocipedes, so as to
impart the principle of the fly wheel thereto. For this purpose we fix to the
axle of a bicycle, tricycle, or other velocipede a boss, which constitutes the central
part of a fly wheel, by nuts and screws or otherwise; the boss is made in two pieces
and is fixed to the machine so as to clasp the axle in the centre between the hubs
or flanges. To the boss is attached the section of the fly wheel; or the apparatus
may, in the making of a new machine, be made in one piece.
The notary motion and power of the fly wheel is obtained from the action of the
bicycle, tricycle, or other velocipede propelled by manual labour; this revolution
communicates increased power to the velocipede in proportion to its. velocity.
to increase its speed and to lessen manual labour, as now used in the crank and
treadles.

page_text: The apparatus is so made that it can be used and attached to any ordinary
bicycle or tricycle, simply as an adjunct, not interfering in any way or altering the
construction thereof, boing so made as to be fitted or removed easily, leaving the
bicycle or tricycle unaltered and intact; or it may be made with and remain as a
permanent part of the velocipede.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Josiah Puntis and Thomas Puntis in the Great Seal Patent Office
on the 15th August 1879.
JOSIAH PUNTIS and THOMAS PUNTIS, both of Upton Park, in the County of
Essex. "IMPROVEMENTS IN BICYCLES, TRICYCLES, AND OTHER VELOCIPEDES OR
WHEELED VEHICLES PROPELLED BY MANUAL LABOUR."
This Invention relates to improved apparatus to be used solely as an adjunct, or
an additional accessory in the propelling of bicycles, tricycles, and other velocipedes,
or wheeled vehicles propelled by manual labour applied by means of treadles, hand
levers, or otherwise.-
This improved apparatus is to be fitted to bicycles, tricycles, or other velocipedes
for accellerating speed, lessening the strain of manual labour, overcoming the
resistance of wind, and for imparting steadiness and elegance to the machine.
And in order that our Invention may be clearly understood and readily carried
into practice, we will now proceed to describe the same with reference to the
Drawings bereto annexed, Figure 1 of which shows a side view of a bicycle having
apparatus applied thereto in accordance with our improvements, Figure 2 being a
separate view on a larger scale of the revolving weighted arms or accelerators.
The method of carrying our Invention into practice consists primarily in the
adaptation, use, and application of the fly wheel or of weighted arms or rods
serving as an equivalent for the fly wheel attached to the axle of a bicycle,
tricycle, or other velocipede, so as to impart the principle of the fly wheel
thereto.
For this purpose we fix to the axle a of a bicycle (or to a tricycle or other
velocipede) a boss b, which constitutes the central part of a fly wheel by nuts and
screws 6¹, as shown or otherwise. The boss b is made in two parts, and is fixed to
the machine so as to clasp the axle a in the centre between the hubs or flanges.
To the boss b is attached the section of the fly wheel; or the apparatus may, in
the making of a new machine, be made in one piece; 62, 63, are the weighted arms,
and 68, weights at the end thereof. The number of the weighted arms 63 may be
varied.
The rotary motion and power of the fly wheel is obtained from the action of the
bicycle, tricycle, or other velocipede propelled by manual labour. This revolution
communicates increased power to the velocipede in proportion to its velocity, to
increase its speed, and to lessen manual labour as now used in the crank and treadles.

page_text: This apparatus is so made that it can be used and attached to the axle of any
ordinary bicycle, or tricycle, simply as an adjunct, not interfering in any way or
altering the construction thereof, being so made as to be fitted or removed easily,
leaving the bicycle or tricycle unaltered and intact; or it may be made with and
remain as a permanent part of the velocipede.
The boss and revolving weighted arms may be so applied to the axle a as to
be readily released in order that the axle a may run freely in the boss b without
causing it and the arms 6s to revolve when descending steep inclines.
Having thus described the nature of our Invention and the manner of performing
or carrying the same into practice, we would remark that we do not claim any of
the parts separately, which are well known and in common use,―
But what we claim is, the improved arrangement, adaptation, and application to
bicycles, tricycles, and other velocipedes of a fly wheel or revolving weighted
arms, substantially in the manner and for the purposes herein before described, and
represented in the Drawings hereto annexed.
In witness whereof, I, the said Thomas Puntis, have hereunto set my hand
and seal, this Thirteenth day of August, in the year of our Lord One
thousand eight hundred and seventy nine..
THOMAS PUNTIS. (LS)
