page_text: PROVISIONAL SPECIFICATION.
A New or Improved Reversing Apparatus for Motor-driven
Vehicles,
We, BENJAMIN JOSEPH JACOBS of Briar Cottage, Yeovil, Inventor, and "THE YEOVIL
MOTOR CAR AND CYCLE COMPANY LIMITED" of Yeovil, Somerset, do hereby declare
the nature of this invention to be as follows:-
This invention relates to a new or improved reversing apparatus for motor-driven
vehicles especially in the case where the motor is kept constantly running in one
direction with means interposed to transmit such motion to drive the vehicle forward
or backward or to disconnect same so that the vehicle can come to a standstill with
the motor still running.
The present invention is as follows:-
The crank shaft or other shaft operated by the motor transmits power to an
intermediate wheel by means of a driving belt or endless band or equivalent this
wheel being carried on a pivotted arm or lever to which latter a treadle (or other
means) is connected to operate said lever either by the foot or by hand-the pivot or
axis on which this lever is mounted being advantageously on a rocking arm or slide
or other suitable arrangement such that when the end of the lever carrying the
aforesaid intermediate wheel is moved vertically same will simultaneously receive
horizontal or curvilinear movement.
Adjacent to this intermediate wheel is an idle wheel (advantageously a band wheel
around or upon which a band or other brake may act such band brake being clear of
the reversing mechanism) this idle wheel having fixed rigidly thereto or on the same
axle therewith a toothed wheel around which latter an endless chain passes this chain
also passing around a chain wheel on the driving axle of the vehicle or on the driving
wheel or wheels of the vehicle so that in whichever direction the vehicle is travelling
by means of the aforesaid chain and chain wheels thereby the aforesaid idle wheel is
always rotated either forwards or backwards.
To reverse the vehicle-the motor is disconnected from the driving wheel or driving
wheel axle and then the aforesaid intermediate wheel on the aforesaid lever is moved
into contact with the aforesaid idle wheel the arrangement advantageously being such
that the driving belt from the motor to the said intermediate wheel bears against
said idle wheel and partly encircles said idle wheel.
By this means said idle wheel is now driven in the opposite direction to which it
is driven by the aforesaid endless chain when the vehicle is running forward and
consequently the vehicle is now driven through the aforesaid chain from the idle
wheel in the reverse direction i.e. backwards.
Any suitable means may be used to connect and disconnect the motor from the
driving shaft or driving wheel shaft or driving wheels of the vehicle the arrangement

page_text: being advantageously such that the forward drive must be disconnected before the
reversing apparatus can come into operation.

COMPLETE SPECIFICATION.
A New or Improved Reversing Apparatus for Motor-driven
Vehicles.
We, BENJAMIN JOSEPH JACOBS of Briar Cottage, Yeovil, Inventor, and "THE
YEOVIL MOTOR CAR AND CYCLE COMPANY LIMITED of Yeovil, Somerset, 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 :-
This invention relates to a new or improved reversing apparatus for motor-driven
vehicles especially in the case where the motor is kept constantly running in one
direction with means interposed to transmit such motion to drive the vehicle
forward or backward or to disconnect same so that the vehicle can come to a standstill
with the motor still running.
The present invention is as follows:-
The crank shaft or other shaft operated by the motor transmits power to an
intermediate wheel by means of a driving belt or endless band or equivalent this
wheel being carried on a pivotted arm or lever to which latter a treadle (or other
means) is connected to operate said lever either by the foot or by hand-the pivot
or axis on which this lever is mounted being advantageously on a rocking arm or
slide or other suitable arrangement such that when the end of the lever carrying
the aforesaid intermediate wheel is moved vertically same will simultaneously receive
horizontal or curvilinear movement.
Adjacent to this intermediate wheel is an idle wheel (advantageously a band wheel
around or upon which a band or other brake may act-such band brake being clear
of the reversing mechanism) this idle wheel having fixed rigidly thereto or on the
same axle therewith a toothed wheel around which latter an endless chain passes
this chain also passing around a chain wheel on the driving axle of the vehicle or on
the driving wheel or wheels of the vehicle so that in whichever direction the vehicle
is travelling by means of the aforesaid chain and chain wheels thereby the aforesaid
idle wheel is always rotated either forwards or backwards.
To reverse the vehicle-the motor is disconnected from the driving wheel or
driving wheel axle then the aforesaid intermediate wheel on the aforesaid lever is
moved into contact with the aforesaid idle wheel the arrangement advantageously
being such that the driving belt from the motor to the said intermediate wheel bears
against said idle wheel and partly encircles said idle wheel.
By this means said idle wheel is now driven in the opposite direction to which it
is driven by the aforesaid endless chain when the vehicle is running forward and
consequently the vehicle is now driven through the aforesaid chain from the
idle wheel in the reverse direction i.e. backwards.
Any suitable means may be used to connect and disconnect the motor from the
driving shaft or driving wheel shaft or driving wheels of the vehicle on the forward
drive the arrangement being advantageously such that the forward drive must be
disconnected before the reversing apparatus can come into operation,

page_text: DESCRIPTION OF THE DRAWINGS,
Referring to the accompanying drawings-
Fig. 1 is a side elevation showing reversing apparatus ready for use-but not
applied.
Fig. 2 is a similar view showing the reversing apparatus in action,
Fig. 3 is a plan of Figs. 1 and 2.
A is the notor cylinder (such as an explosion motor) by which the main shaft B
is revolved and the power for driving the vehicle forward is transmitted from said
shaft B to the driving wheel or wheels in any suitable manner by any suitable means
not shown.
C is a small pulley on the crank shaft B from which power is taken by the belt D
to the jockey pulley E which latter is carried (pivotted at E¹) on the pivotted arm
or foot lever F which foot lever F is pivotted at Fx to the link & the latter being
pivotted at G¹ to the frame X.
The other end of said foot lever F is bent downwardly at F1 and then extends
forwardly and terminates in the treadle F2.
H is a pulley fixed on an intermediate or lay shaft I from which latter power may
be transmitted to the driving wheels of the carriage in any suitable manner or by
any suitable means-not shown.
By pressing down the lever F by means of the treadle F2 from the position
shown in Fig. 1 into the position shown in Fig. 2 thereby the back of the belt D
comes in contact with the pulley H on the lay shaft I and partially laps around same
as shown in Fig. 2 the link motion (G) allowing the belt to stretch when the
reversing motion is applied until the jockey pulley E is forced down tightly against
the pulley H and so applies a powerful grip and thereby the pulley I is revolved and
the reversing motion of the vehicle thus effected without reversing the motor.
When the reversing gear is not in connection the foot lever F is kept up by means
of a spring such as J Fig. 1.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what we
claim is:-
1. In reversing apparatus for motor-driven vehicles-the combination with a motor
of a pulley such as C driven by said motor a jockey pulley such as E carried on a
pivotted arm or lever such as F and adapted to be moved towards and away from
an intermediate pulley such as H and an endless driving band or belt such as D) on
said pulleys C and E adapted to be forced by the latter against the said pulley H
and thereby reverse the direction in which said vehicle is driven substantially as and
for the purposes described and illustrated in the drawings hereunto annexed.
2. The improved reversing apparatus constructed combined and arranged to act
in conjunction with a motor substantially in the manner and for the purposes
herein before described and illustrated in the drawings hereunto annexed.
