page_text: I, THOMAS DICKENSON SWIFT, Managing Director Ince Wagon & Ironworks
Co. Limited, of Lower Ince, Wigan, in the County of Lancaster, do hereby
declare the nature of this invention to be as follows:-
This invention relates to brake apparatus for railway wagons and other rolling
stock for railways.
One way of carrying my invention into effect is to provide near one end of the
wagon a rocking shaft which passes under the wagon frame from one side of the
wagon to the other, at one or both ends of which auxiliary hand levers are fixed
with cranks, the latter being coupled to the end of the main brake lever by means
of a connecting rod. The hand levers or the rocking shafts may be weighted, or
both may be weighted if required but this is not necessary. Near the other end
of the wagon is a similar rocking shaft which passes under the wagon from one
side of the wagon to the other, on one or both ends of which auxiliary hand
levers are also fixed. The two rocking shafts are cranked at one part in their
length, and the two cranks coupled together by a connecting rod. Thus I provide
a handle either at two opposite corners of the wagon or on all four corners which-
ever is preferred, and either hand lever will work the brake.
To apply the brake all that is necessary is to take hold of one of the hand
levers, and throw it from one side to the other and press hard down. This forces
down the main brake lever which applies the brake blocks to the wheels. As
soon as the crank on the hand lever gets a little past the perpendicular, it locks
the blocks or tightly fixes them against the wheel, the greater the pressure, the
tighter will the blocks be held against the wheels and the cranks cannot accidently
spring back through vibration. By throwing the hand lever back in the opposite
direction by hand, the brake is released from the wheels and the weights as soon
as they pass the perpendicular keep the blocks off the wheels.
In conjunction with this apparatus I may also provide springs adapted to
hold the brakes half on. For this purpose they are adapted to either press against
the cranks or against discs or other appliance fixed on the rocking shafts, so
that at one point in their rotation these springs will come into operation and
hold the brake blocks with half pressure on the wheels instead of full pressure.
Thus I am able to obtain three or more positions for my brake, namely off, hard
on, and one or more degrees of pressure intermediate between off and hard on.
It will be obvious that in the case of those vehicles which are provided with
main brake levers on each side, that the hand levers on each rocking shaft may be
counterparts of each other, the cranks on each of them being coupled to their
respective main brake levers by means of a connecting rod.
In another arrangement I provide the main brake lever with teeth, and provide

page_text: a toothed segment, pivoted eccentrically to the rocking shaft, and gearing into
the teeth on the hand lever. The segment has an auxiliary hand lever. When
this is pulled over, the segment being eccentric, will depress the main lever and
apply the brake blocks, and owing to the teeth the main lever will be held in
almost any position required. When the largest radius of the segment passes
the perpendicular, then the blocks will be held firmly against the wheels, and the
greater the pressure the firmer will they be locked.
In another arrangement I slot the end of the brake lever and arrange that
the end of a crank on the auxiliary hand lever or on the rocking bar shall engage
in this slot. The auxiliary hand lever is secured to the rocking shaft which is
weighted, and in the off position of the brake the auxiliary hand lever is about
upright with the weight well past the perpendicular so as to keep the brake
lever raised. To apply the brake all that is necessary is to pull down the
auxiliary hand lever and its crank pin sliding along the slot in the brake lever
pushes down the latter and so applies the brake. As soon as the crank has passed
the perpendicular and its pin abuts against the end of the slot, the brake is
tightly fixed against the wheels, and the weight tends to keep it there and prevent
it accidentally getting unlocked through vibration or otherwise.
If desired either of these arrangements can be arranged to put the brake in and
out of action without balance weights. Among the advantages of the invention
may be mentioned that the apparatus is self retaining in either position, no
pin or tooth rack being necessary, nor lever Fest to hold the brake either on or
off. Furthermore if a hand lever be fixed to each end of the rocking shaft, the
apparatus can be worked from either side of the vehicle.

Improvements in Brake Apparatus for Railway Wagons
or like Vehicles.
I, THOMAS DICKENSON SWIFT, Managing Director Ince Wagon & Ironworks
Co., Limited, of Lower Ince, Wigan, in the County of Lancaster, 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 brake apparatus for railway wagons and other rolling
stock for railways.
The invention will be understood from the following description, reference
being had to the accompanying drawings, in which,
Fig. 1 is a side elevation of my brake applied to a wagon showing the brake on;
Fig. 2 a similar view showing the brake off;
Fig. 3 a plan.

Referring to these figures, A are. the sole bars of the wagon, B the hangers for
the cross. shafts, and C the Vee hangers. Near one end of the wagon I provide
a rocking or cross shaft D which passes under the wagon from one side of the
wagon to the other, at one or both ends of which auxiliary hand-levers E are
fixed with cranks F, the latter being coupled to the end of the main brake

page_text: will come into operation and hold the brake blocks with half pressure on the
wheels instead of full pressure, substantially as described.
3. The improved hand actuated lever brake apparatus for railway wagons and
the like, constructed, arranged and operating substantially as hereinbefore
described, with reference to and shown in the drawings annexed.
