Year: 1899

Complete Specification Left, 1st Feb., 1900-Accepted, 3rd Mar., 1900
I, WILLIAM ALLAN, of 97, North Frederick Street, in the County of the City of
Glasgow, Waggon Inspector, do hereby declare the nature of my invention to
be as follows:
This invention has reference to and comprises improvements in and relating to
brakes for railway waggons and has for its object to enable the brake to be
operated from either side of the waggon, and is applicable to waggons fitted with
brakes either on one side or both sides.
In carrying the improvements into practice the free end of the long horizontal
brake lever is suspended between the side plates of a duplex link jointed to the
lower end of a short lever jointed at its upper end to the waggon frame. The
end of the long lever is adjustably held between the side plates of the link by a
pin passing through holes in same. A series of these holes are formed to enable
the position of the brake lever being adjusted to the wear of the brake. When
the brake is out of action the duplex link and its suspending lever lie at an
angle to one another. A bell crank lever having a short arm which may be
formed with a turned over end, and a long pendent curved arm to serve as a
handle, is mounted on one end of a spindle carried transversely on the waggon
frame by eyes or bearings, and has its short arm jointed by a short link to the
meeting ends of the duplex link and its suspending lever. When the pendent
arm of the bell crank lever is raised its short arm, through the link, draws the
ends of the duplex link and lever until they are approximately in a straight
line which movement presses down the brake lever end and applies the brake.
On depressing the long arm of the bell crank lever the brake is at once released.
A pendent handle is secured to the end of the transverse spindle on the side of
the waggon opposite to that on which the brake is fitted so that it can be operated
from either side.

Improvements in and relating to Brakes for Railway Waggons.
I, WILLIAM ALLAN, of 97, North Frederick Street, in the County of the City of
Glasgow, Waggon Inspector, do hereby declare the nature of my invention and
in what manner the same is to be performed to be particularly described and
[Price 8d.1

page_text: ascertained in and by the following statement in writing, reference being made
to the accompanying drawings:
This invention has reference to and comprises improvements in and relating
to brakes for railway waggons, and has for its object to enable the brake to be
operated from either side of the waggon, and is applicable to waggons fitted with
brakes either on one or both sides."
And in order that my invention may be properly understood I have hereunto
appended two sheets of explanatory drawings in which the same reference letters
are used to indicate the same or equivalent parts, in all the figures where shown.
Figure 1 on Sheet 1 is a side view of part of a waggon fitted with my improve-
ments in which the lever is shown as actuated from above.
Figure 2, on sheet 2, shows the improvements, as applied to a waggon with
falling sides, Figures 3 and 34 illustrate the improvements as fitted with a
pendent lever, and Figure 4 illustrates a locking rack and pawl arrangement.
Referring to the drawings:-In carrying the improvements into practice the
free end of the long horizontal brake lever A is-suspended between tlie side plates
of a duplex link B jointed to the lower end of a short lever C jointed at its upper
end to the waggon frame 1). The end of the long lever A is adjustably held
between the side plates of the link B by a pin, not shown in the drawings, pass-
ing through holes 6 in same. A series of the holes bare formed to enable the
position of the brake lever A to be adjusted to the wear of the brake. When the
brake is out of action the duplex link B and its suspending lever C lie at an
angle to each other.
As shown in Figure 1, a lever E is secured on one end of a spindle E2 carried
transversely on the waggon frame by eyes or bearings E3 and a projection e on
the lever is jointed by a short link F to the meeting ends of the duplex link B
and its suspending lever C. The upper part E of the lever E is turned over
to form a handle and the lever may be fitted with a retaining rack G¹ and
pawl e as illustrated by Figure 4 on sheet 2.
When the lever E is oscillated to the position shown in dotted lines, it draws,
by means of the link F, the ends of the duplex link B and lever C until these
levers are approximately in a straight line, which movement presses down the
end of the brake lever A. and applies the brake.
If the link B and lever C are drawn beyond the position of being in line the
brake will be held in action automatically until relieved by the return of the
lever E to its relieving position.
A lever and handle similar to EE are secured on the other end of the
spindle E to operate the brake from the other side of the waggon.
Figure 2 on sheet 2, illustrates the application of my improvements to a
waggon fitted with falling sides where the space is limited, and the lever E is
made much shorter so as to have room to oscillate and is also formed as a bell
crank lever, the short arm c of which is jointed to the link F. The end of the
lever is turned over at E¹ to form a handlè; and a similar lever is secured on the
other end of the spindle E².
The action is the same as that. of the modification described except that the
lever. E may oscillate through a larger arc to apply the brake as indicated in
dotted lines.
As illustrated by Figures 3 and 3* the lever E is pendent and formed as
belt crank lever having a short arm e which is formed with a turned over end e²
and a long arr which serves as a handle. This lever E is mounted on the end
of the spindle E3 and has its short arm e 2 jointed by the link F to the meeting
ends of the duplex link B and its suspending lever C. When the pendent arm E
of the bell crank lever is raised its short arm e e, through the link F, draws the
ends of the duplex link B and lever C until they are approximately in a straight
line which movement presses down the brake lever A and applies the brake. On
depressing the long arm of the bell crank lever the brake is at once released. A

page_text: pendent handle is secured to the end of the transverse spindle on the side of the
waggon opposite to that on which the brake is fitted so that it can be operated
from either side.
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:-
First. The construction or arrangement and combination of the parts of lever
mechanism for operating the brake levers of railway waggons from either side
substantially as herein described and illustrated by the accompanying drawings.
Second. In lever mechanism for operating the brakes of railway waggons from
either side the combination with the brake lever A of the duplex link B, suspend-
ing lever C, link F, lever E, and transverse spindle E substantially as herein
described and illustrated by the accompanying drawings.
Third. Lever mechanism for operating the brake levers of railway-waggons
constructed and arranged substantially as herein described and illustrated by
the accompanying drawings.
