AMOS MORONY VEREKER, of 31' Wellington Place Clyde Road Dublin and
STEPHEN MITCHELL YEATES of 2 Grafton Street Dublin Optician do hereby
declare the nature of our invention for aforesaid " STARTING GEAR FOR TRAM
CARS AND OTHER VEHICLES" to be as follows:-
Our invention has for its object improvements in the construction of Tram Cars
and other Vehicles whereby the Strain upon, or Effort of, the Horse or Horses to
Start the Vehicle is reduced-Our said invention consists of an Automatic
Arrangement which acting as a Break to Stop the Car, Stores up the Momentum
in such a way as to be available for Starting again when required--this being
accomplished by the use of pinions on the Axles gearing. into a Rack governed by
a. Spring.
We, AMOS MORONY VEREKER 31 Wellington Place Clyde Road Dublin Gent
& STEPHEN MITCHELL YEATES 2 Grafton Street Dublin Optician do hereby declare
the nature of our invention for STARTING GEAR FOR TRAM CARS & OTHER
VEHICLES, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
An Automatic Arrangement, which acting as a break to Stop the Car, stores
up the momentum availably for Starting again by having on each axle (when both
wheels are fixed) a loose Spurwheel or pinion A. A' with a friction clutch or
chuck E. E Those pinions both gear into a strong rack R, constructed so that
one part is over and gearing into one pinion while the other part is under and
gearing into the other pinion-This rack is held in its normal position by a strong
Spring C, and is provided at one end with a ratchet K. and a pall or click Ď
opposed to it-Rod L communicates between the driver and the friction clutch E.

page_text: The rod L¹ joins E² to friction clutch E The bars E. E' are held by latches or
bolts F. F to the traction bars G. G¹ when the rack is wound up. Rods H. H¹
connect the cross bars E. E¹ to the pall or click D.-The friction clutches and
the connecting rods are duplicated for use similarly from the other end
The
action is as follows-Suppose the Car running in the direction indicated by the
arrow.
The driver wishing to stop applies his break, and by the lever L. throws in the
friction clutch locking the pinion A, which being carried round by the motion
of the Car runs back the rack, compressing the spring, until its rapidly increasing
strength brings the Car to rest the rack being held by the pall D. and the driver
takes off his break and releases (by L) the friction clutch E. and pinion A.
When next starting the pull by the Horses, first throws in the friction-
cluteblocking the Pinion A¹, and then disengages by the rod H³ the pall D,
releasing the rack which moves or helps on the Car in the direction in which it
had been going.
A wedge on the end of the rack (or other similar arrangement) as the rack runs
down unlocks the latch F¹ and sets the pinion A¹ free leaving all again in its
normal position.
In the case of Cars having one wheel loose and one tight on each axle we propose
the addition of a friction clutch to the loose wheel, acting similarly to, and
simultaneously with, the one gearing into the pinion which is being driven by
the rack.
Or, preferably, with all wheels running free, and the pinions solid with the
axles The friction clutches being applied to the wheel (instead of to the pinions)
locking them to the axles when required, as heretofore described.
We also propose that a key be provided to operate the pall D thro' the floor of
the Car, so that in the event of the Car over-running the points, the Spring would
be used to reverse the wheels and run the Car back, thus relieving the horses of
perhaps a greater strain than that of starting.
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
Firstly The use of a rack or chain passing over one axle, and under the other
us described.
