PROVISIONAL SPECIFICATION.
Improvements in Brakes for Railway Trucks and other Vehicles.
We, THOMAS HILTON, of 75, Shaw Road, Oldham, in the County of Lancaster,
Plumber, Joux SAMUEL HULTON, of Side Bank, Greenfield, in the County of
York, Accountant, and JAMES HOLT, of 6, Beech Street, Oldham, aforesaid,
Manager of the Albion Club, Oldham, do hereby declare the nature of this in-
vention to be as follows:-
:-
Our said invention relates to brakes which are chiefly applicable to railway
trucks but which may also be applied to other vehicles.
At present railway trucks are braked by means of a lever arranged at one side
of the truck, which lever actuates a brake block. As this lever is arranged at
one side only of the vehicle accidents frequently happen to men passing between
or beneath the trucks to get at the brake lever.
The object of our invention is to provide an efficient brake which can be
actuated from either side of the vehicle and thus obviate a fruitful source of
accidents.
In carrying our invention into effect we provide a shaft arranged across the
width of the waggon or truck between the wheels and mounted to revolve in
suitable bearings. This shaft is provided at both ends with a handle, hand wheel,
or lever and carries centrally a worm. The worm gears with a suitable worm
wheel mounted to revolve in bearings provided by a bracket secured to the under
framing of the truck. The bearing bosses of the worm wheel are formed as nuts
within which are screwed spindles connected to levers formed on or secured to
rock shafts which carry at each end levers provided with brake blocks.
By revolving the central worm shaft by means of the handle the worm wheel
is correspondingly rotated traversing the screwed spindles which thus actuate
the rock shafts and bring all the four brake blocks to bear with any desired
pressure against the periphery of the wheels.
Thus not only can the brake be actuated from either side of the trucks but the
brake power is distributed more efficiently being directly applied to four wheels.
The reverse rotation of the handle removes the brake blocks from contact with
the wheels. If desired and particularly in case of road vehicles one screwed
spindle only actuating a rock shaft provided with brake blocks could be used.
In some cases, and so as not to lie over or interfere with the draw hooks and
connections, we might employ two worms gearing with duplicate worm wheels
which operate duplicate sets of screwed spindles.

We, THOMAS HILTON, of 75, Shaw Road, Oldham, in the County of Lancaster,
Plumber, JOHN SAMUEL HULTON, of Side Bank, Greenfield, in the County of
York, Accountant, and JAMES HOLT, of 6, Beech Street, Oldham, aforesaid,
Manager of the Albion Club, Oldham, do hereby declare the nature of this in-
vention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement and accompanying
drawings:-
•
Our said invention relates to brakes which are chiefly applicable to railway
trucks but which may also be applied to other vehicles.
At present, railway trucks are braked by means of a lever arranged at one side
of the truck, which lever carries or actuates a brake block. As this lever is
arranged at one side only of the vehicle, accidents frequently happen to men
passing between the ends or beneath the trucks to get at the brake lever.
The object of our invention is to provide an efficient brake which can be
actuated from either side of the vehicle.
By the provision of such a brake it is no longer necessary to pass between the
ends of the trucks so that we obviate what has hitherto been a fruitful source
of accidents.
Our invention will be clearly understood from a perusal of the following de-
scription in which reference is made to the annexed sheet of drawings.
In the said drawings.
Fig. 1 is an inverted plan view of an ordinary railway waggon with our
improved brake applied thereto.
Fig. 2 is a side elevation of the waggon and improved brake, the braking sur-
faces being shown in contact with the truck wheels.
Fig. 3 indicates a modification of the improved brake.
Fig. 4 indicates a further modification of our invention.
In carrying our invention into effect, we provide a shaft a arranged across the
width of the waggon or truck, between the sets of wheels B. This transverse
shaft a, is mounted to revolve in suitable bearings a¹, and is provided at each
end with a hand-wheel b. Instead of hand-wheels b suitable handles or levers
might be employed. The said transverse shaft a is formed with or carries a
centrally situated worm c which gears with a worm wheel d. The worm wheel d
is sustained by and mounted to revolve between bearings e carried by brackets f
securing to the under-framing of the truck. We form the worm wheel d and
its bearing bosses as a nut such worm wheel being tapped right and left hand so
as to engage right and left-hand screwed spindles g. These screwed spindles
are pivottally connected to levers or links h formed on or secured to rock
shafts . The rock shafts i are supported in bearings and carry at each end
levers j, which are provided with suitable brake blocks, or other convenient
braking surfaces. We may employ hinged brake blocks or not as desired.
The operation of our improved brake is as follows.
On revolving the centrally situated worm shaft a, by means of one or other
of the hand wheels b, the worm wheel d is correspondingly rotated, traversing
the screwed spindles g g, which in turn, actuate the rock shafts ii so as to bring
all four brake blocks to bear with any desired pressure against the periphery of
the wheels. Thus, not only can the brake be actuated from either side of the
truck, but the brake power is distributed more efficiently, being directly and
equally applied to all four wheels. The reverse rotation of a handle removed

page_text: the brake blocks j¹ from contact with the wheels. A brake, such as we have
described, is exceedingly powerful in use and is simple in construction.
If desired, one screwed spindle c only, actuating a single rock shaft provided
with brake blocks, might be used. This construction is clearly indicated in
Fig. 4 and is particularly suitable for use in connection with road vehicles.
in some cases in order that the worm wheel d shall not lie immediately over
and so interfere with a ready access to the draw-hook extensions and connections
we might employ two worms gearing with duplicate worm wheels and operating
duplicate sets of screwed spindles g. An arrangement of this kind is shown in
Fig. 3 the worm wheels d d in this case being disposed equi-distant from a line
drawn down the longitudinal centre of the waggon.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we wish it to be
understood that we are aware that it has already been proposed to operate the
brakes of railway wagons by a transverse shaft which can be rotated from either
side of the wagon, and that in one form of apparatus such transverse shaft
carries a worm which engages with a tangent lever, and we make no general
claim to such arrangements, but we declare that what we claim is:-
1) A brake, for railway waggons and the like, having a cross shaft capable
of being operated from either side of the waggon, the motion of such shaft being
communicated by worm gear to screwed spindles, or it might be to one screwed
spindle, the said screwed spindles operating rock shafts, which are provided with,
or actuate brake blocks, substantially as herein described.
2) The general arrangement construction and combination of parts comprising
the improved forms of brake for use in connection with railway waggons and
road vehicles substantially as described and shown in Figs. 1, 2, 3 and 4 of the
drawings hereto.
