PROVISIONAL SPECIFICATION.
Improvements in Hand Power Brakes for Railway Wagons and
similar Vehicles.
I, DAVID JOHN MORGAN, of Aberthaw House, Barry, in the County of
Glamorgan, do hereby declare the nature of this invention to be as follows:-
This invention relates to certain improvements applicable further to an in-
vention described by me in my application for a Patent No. 23264 of 1899 and
the object of my present invention is to so improve the counterbalancing
mechanism of the brake that the brake levers may be more easily operated and
any danger to the counterbalance weight getting adrift is obviated and further
a longer counter balance lever may be used than is possible with brake counter
balance mechanism as hitherto arranged and therefore a lighter weight may
be used, to attain which I secure to the axle brake a lever or levers which
extend in the same direction as the brake levers and I suspend to said lever or
levers suitable weight or weights which slide within or are surrounded by a
basket cylinder or other case extended from bottom of wagon. The cord, chain
or other band which suspends the weight to each counter balance lever may
pass over one, two or more pullies or may pass over a series of pullies, blocks
or sheaves similarly arranged to well known lifting tackle and one of these
blocks may receive the weight and they may be suspended from bottom of
wagon or on brackets and all may be protected by and work within a cage.
Instead of a balance lever or levers as aforesaid a lever-wheel, segment, lever,
bell-crank, arm or similar device may be fixed to brake axle and may receive
the end of a rope, cord or chain which will pass around or over one or more
blocks, pullies or drums as aforesaid and become connected thereby to a counter
balance weight or weights for the purpose of operating the brake levers that
is bringing them to position out of action when released. And these pullies
drums blocks or sheaves together with counter weight or weights may work
within a cage cylinder or other protection as before described.
It will be obvious that in all the ways described for carrying out my present
invention a spring or springs may take the place of the weight or weights
aforesaid and such spring or springs may be either fastened within the cage or
to wagon or to brackets fixed thereto.

Improvements in Hand Power Brakes for Railway Wagons and
similar Vehicles.
I, DAVID JOHN MORGAN, of Aberthaw House, Barry, near Cardiff, in the
County of Glamorgan, Engineer, do hereby declare the nature of this inven-
017

page_text: tion 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 certain improvements applicable further to an in-
vention described by me in my application for a Patent Number 23264 of
A.D. 1899 and the objects of my present invention are:-
1. To so improve the counter-balancing mechanism of the brake that the
brake levers may be more easily operated upon and will return to positions
out of action more freely than is possible to be obtained with ordinary counter-
balancing mechanism as at present in use, and further my herein improved
counter balancing mechanisin automatically retains the brake when out of
action, and
2. To arrange a guard, cage, case, cylinder or similar device in such a manner
that the counter weight, or spring or like mechanical device for bringing the
brake levers when released out of action automatically may be securely pro-
tected and prevented from getting adrift should any of their parts by any
means become detached.
To attain said objects therefore I use mechanism and means substantially
as described with reference to the accompanying drawings in which Fig. 1 18
a side elevation of railway wagon with my improvements attached thereto.
Fig. 2 is an end elevation and Fig. 3 a plan of same.
Fig. 4 is an enlarged cross-section of slide stop or shield lever and connec-
tion taken on line a a of Fig. 1.
Fig. 5 is a perspective view in detail of part of lever and stay showing spring
in lieu of weight for returning the pawl and slide stop or shield over the brake
rack when brake is released.
Fig. 6 is a side view of handle part of lever showing slot in which slide stop or
shield for brake rack works.
Fig. 7 is a cross sectional elevation of modified automatic stop or shield for
preventing brake lever lip engaging with rack unless lateral pressure is used.
Figs. 8 and 9 are side elevations of wagon showing my modified means of
counter-balancing the brake and levers. Similar letters of reference denote
corresponding parts in each view.
I carry the brake axle A in frames or brackets F which are secured to the
wagon.
The brake axle A carries levers 11, 12 and F. The lever is coupled to
end of brake lever L by a connecting rod d.and the said brake lever L is ful-
crumed at P the latter being a shaft carried in the brackets F.
The lever is coupled to brake block W by the rod, the brake block being
suspended by a rod j. The opposite end brake block W is operated by the
lever 13 which works the rod or bar d carried in the parts f¹ and 2 of bracket F.
The levers L are coupled together by two or more stayrods T and the stay
rod T near the handle end is free to work in the levers and has secured to it
a grip lever M, a counter balance weight X, a lever N which is coupled to the
slide stop or brake rack shield Y by the rod n'.
In this arrangement the slide stop or shield Y is made with a shank having
a square party as shown at Fig. 4, to work in slot 15 formed in lever L (see
Fig. 6) and a round party to which the rod is coupled see said Fig. 4.
The free stay rod T receives the ends of cords, chains or ropes which
extend over pullies Q and carry at their opposite ends suitable weights B¹
which are contained within casings, cages, cylinders or other like protective
chambers made with or secured to wagon.
The weights B¹ may where preferred work within casings V arranged under
the wagon as shewn at Fig. instead of at the end as shown at Fig. 1. Or
instead of the weights the cords may be attached to springs B arranged
either vertically or horizontally as shewn at Fig. S in which case shields cages
cylinders or tubes V are arranged for their protection inside or outside of the
wagon.

page_text: To the free stay T are also secured two pawls C which rest on or in the hold-
ing up or out of action racks when brake is out of action and the lips of
levers L (see Fig. 4) are free of the holding down or in action racks R.
Instead of a counter balance weight X coiled springs X may be arranged,
one end fixed to lever L the other to free stay rod T as shown at Fig. 5.
Where desireu the slide stops or brake rack shields Y may be dispensed
with and an automatic spring stop or shield Y arranged with cage or cover y³
and spring y, used instead, in which case the mechanism for operating the
slide stop or shield Y is dispensed with and the levers M only used for liberat-
ing the pawls C, the weight X or springs X' being used for bringing pawl C
into position to mesh with rack R when the lips (see Fig. 4) are released
from holding down or in action racks R.
The combined on and off brake racks R, R' may be made in one piece as
shown, or separately, if the latter the rack R is secured in the ordinary way
to side of wagon and the rack R¹ fastened to same or extended from underside
of wagon and secured thereto.
The teeth of rack R are inclined to prevent the lever L lifting in one direc-
tion, and the teeth of the rack Rare inclined in an opposite direction to pre-
vent the lever L being lowered as will be well understood.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. In hand power brake or brakes for railway wagons and similar vehicles
the combination in brake-lever counter-balancing mechanism of an on and off
rack, pawl, spring or weight and grip lever, with levers or cranks and con-
nections for operating suspended brake block or blocks, and cords, chains, or
ropes connecting main brake lever or levers to suspended weight or weights, or
spring or springs, the weights or springs working within or protected by cages,
casings tubes or cylinders substantially as described.
2. The combination of counter-balancing brake mechanism as aforesaid with
levers having pliable or automatic rack stops or shields and off-rack pawls, and
combined off and on racks arranged in corresponding positions on each side of
wagon substantially as described.
3. The combination in counter-balancing mechanism as aforesaid with levers
and balance weight or spring for operating sliding stops or rack shields for
preventing lever catches engaging with on-racks substantially as described.
