Improvements in or relating to Horse, Steam, or other Tramway
Carriages.
I, DANIEL BUCKLEY, of 79 New Park Road, Salford, in the County of
Lancaster, Schoolmaster, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the propulsion of tram cars around curves.
The
objects of this invention are to enable a tram car whether propelled by horses,
steam, or other tractive force, to be caused to follow the curve of the rails without
being diverted thereto by means of points, and by the use of this invention to dispense
with said points. I attain these objects by the means hereinafter described reference
being made to the accompanying sheet of drawings in which Fig. 1 is an outline plan
view of a portion of a tramcar on a straight line with my invention applied.
Fig. 2 shows the same on a curve.
For the purposes herein before named I attach to the underframe of the body
of a tram car as a by means of a bolt b or an equivalent, a bar e placed transversely
near the leading wheels of the car, and carrying a break block d at either end of
said bar. In applying my invention to tramway cars that are propelled by two
horses abreast, I connect each end of the bar c by means of a chain to the outside
trace e of each horse, the horses being otherwise harnessed to the carriage in the
ordinary manner. When the horses are guided around a curve, the pull on that
chain which for the time is the outer chain will swivel the bar c as in Fig. 2 and
cause the break block d which for the time is the inner break block to act on the
inner wheel, or the wheel that is running on the inner rail of the curve, thereby
preventing said wheel from running freely, at the same time the outer wheel, or
the wheel that is running on the outer rail of the curve will be free to revolve, and
will thereby travel more quickly around the outer rail of the curve.
By these means the wheels will follow the curved direction of the rails upon
which the horses divert the car from the straight line, and the necessity, for
employing points will be avoided.
When my invention is applied to single horse cars, each trace e is connected to
one end of the bar c.
When my invention is employed in cars that are propelled by steam or other
motive force, the bar c is actuated by the driver by means of a suitable lever, which
may be combined with toothed wheel gearing. For the purposes of. this invention
the wheels g may be fast on their axles as at present, or one or both of said wheels.
may run loose on the axle, and may be fitted with ball bearings.
In a modification of my invention the break blocks d may be fitted to the ends
of the bar e with the intervention of compression springs and said transverse bar
fitted permanently to the underframing of the body of the tram car.
The break blocks d may be applied at the side of the wheels, or they may be of
wedge form and applied between the tops of the wheels and the bottom side of the
carriage.

Improvements in or relating to Horse, Steam, or other Tramway
Carriages.
I, DANIEL BUCKLEY of 79 New Park Road, Trafford Road, Salford, in the
County of Lancaster, School-master, 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 the propulsion of tramcars and like vehicles around
curves.
The objects of this invention are to enable a tramcar or like carriage whether
propelled by horses or by steam or by other motive force, to be caused to follow
a curve of the rails without being diverted thereto by means of points, and by these
means to dispense with said points. I attain these objects in the manner hereinafter
described reference being made to the accompanying sheet of drawings illustrating
my said invention in which Fig. 1 is a plan representing a part of the underframe
of a tram car, and Fig. 2 is a side view of the same showing my invention applied
to a carriage that may be drawn by one or a pair of horses. In these drawings
similar letters refer to similar parts. For the purposes herein before named I
attach to the underframe of the body of a tramcar as a by means of a swivel bolt b
or an equivalent, a bar o placed transversely near to the leading wheels of the
car. I connect each end of said bar to a wedge shaped break block d that is
supported by and formed to work in a slide as d' attached to the underframe of the
carriage. In applying my invention to a tramway car that is drawn by horses, I
connect the ends c' and c of the bar c to an ordinary tracer bar e by means of chains
or connecting rods fand f' said tracer bar having additional bars e¹ and et connected
therewith in the usual manner when two horses abreast are employed, or the bar c
may be attached at each end by means of a chain or equivalent to the outside
trace of each horse, the horses being harnessed to the carriage in the ordinary
manner.
.
с
When the horses are guided around a curve, the pull on that chain which for the
time is the outer chain will swivel the bar c and cause the break block d which for
the time is the inner break block to act as a wedge on the inner wheel, or the wheel
that is running on the inner rail of the curve, thereby preventing said wheel from
running freely at the same time that the outer wheel or the wheel that is running
on the outer rail of the curve will be free to revolve and will thereby travel more
quickly around the outer rail of the curve.
By these means the wheels will follow the curved direction of the rails upon
which the horses divert the car from the straight line and the necessity for
employing points will be avoided.
When my invention is employed in cars that are propelled by steam or other
motive force the bar c is actuated by the driver by means of a suitable lever which
may be combined with toothed wheel gearing.
In a modification of my invention the break blocks d are attached to the bar in
a position to act on the sides of the wheels, and either with or without the
intervention of springs, in lieu of the wedge form of blocks herein before described.
Stops may be employed to limit the extent of force applied to the wheels.
For the purposes of this invention one or both wheels may run loose on the axle,
and may be fitted with ball bearings.
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1st. In tramcars and like vehicles the application thereto of break blocks as d

page_text: that are attached to a swivel bar as c or an equivalent and actuated either by the
ordinary horse traction or by the driver of the vehicle so as to cause one of said
blocks to press on or against the side of the wheel that is running on the inner rail
of a curve and retard said wheel when the car or carriage is required to pass
around said curve in the manner and for the purpose substantially as hereinbefore
described.
2nd. In tramcars and like vehicles the combination therewith of a swivel bar
as or an equivalent and break blocks as d acting on the wheels of which one
wheel may be fast and one wheel loose on the same axle, or both wheels loose
on the same axle, in the manner and for the purpose substantially as herein before
described.
