• Complete Specification Left, 6th Dec., 1899-Accepted, 6th Jan., 1900
I, HAYDON PARKER, of 54, Avenue Road, Forest Gate, in the County of Essex,
Railway Coach Builder, do hereby declare the nature of this invention to be as
follows:-
Heretofore where it was desired to operate the ordinary long hand lever wagon
brake from either side of the wagon, à long hand lever was fitted on each end
of a cross shaft, which also carries the two levers for the push rods. The objection
to this arrangement is that, in the case of an either side brake, the weight to be
lifted in releasing the brake is doubled, as compared with the already heavy
single long hand lever arrangement.
Now according to my invention I provide on one side of the wagon a short
cross shaft upon which are mounted the two levers for the push rods, and upon
this shaft I fix a short vertical lever which by a connecting rod is jointed to
the upper arm of a bell crank lever fixed on a cross shaft arranged at or near
one end of the wagon, and the other horizontal arm of which bellcrank lever forms
the hand lever for actuating the brake from that side of the wagon. Upon the
other end of the same cross shaft I fix a horizontal hand lever for operating the
brake from the other side of the wagon by a similar action. Thus the weight
of the usual long horizontal hand lever, or hand levers, in the case of an either
side brake, are done away with, the operation of putting on the brake is greatly
facilitated and the operation of taking off the brake involves practically only the
lifting of the two short hand levers. A toothed rack is provided on one or
both sides of the wagon for a tooth on one or both hand levers to engage with.
In order to disengage the hand lever or levers from either side I provide as
described in my Patent Specification No. 5099% a double armed lever with rods
connected to the hand levers, or similar arrangement.

I, HAYDON PARKER, of 54, Avenue Road, Forest Gate, in the County of Essex,
Railway Coach Builder, 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:—
Heretofore where it was desired to operate the usual long hand lever wagon

page_text: brake from either side of the wagon, a long hand lever was usually fitted on
each end of a cross shaft which carries the two levers for the push rods. The
objection to this arrangement is that in the case of an either side brake the weight
to be lifted in releasing the brake is doubled as compared with the already single
longhand lever arrangement. Now according to my invention I overcome this
objection, all as hereinafter described with reference to the accompanying
drawings.
Fig. 1 is a side view, Fig 2 an end view and Fig. 3 a plan view of my brake
gear arrangement applied to a goods wagon. I provide on one side of the
wagon a short cross shaft A upon which are mounted the two levers B B for
the push rods C, and upon this shaft I fix a short vertical lever D) which by a
connecting rod E is jointed to one arm F of a bell crank lever F G fixed on
a cross shaft H arranged at or near one end of the wagon, the other horizontal
arm G of which forms the hand lever for actuating the brake from that side
of the wagon. Upon the other end of the same cross shaft H I fix a horizontal
hand lever G¹ for operating the brake from the other side of the wagon by a
similar action. Thus the weight of the usual long horizontal hand lever, or
hand levers, in the oase of an either-side brake are done away with, the operation
of putting on the brake is greatly facilitated and the taking off the brake
involves practically only the lifting of the two short hand levers G and G¹.
A toothed rack I is provided on one or both sides of the wagon for a tooth on
one or both hand levers to engage with. In order to disengage the hand lever
or levers from either side by a similar motion I provide as described in my
Patent Specification No. 5099 of 1896 a double armed lever L on the cross
shaft H in this example, said lever being connected to the hand levers G and G¹
by rods K. The hand levers although short are of such a bow shaped form,
as shewn as to permit of a certain amount of feathering or spring action.
Fig. 4 is a side view of a similar arrangement of brake gear differing from
that just described mainly by the position of the cross shaft H, which in this
case is placed more towards the middle of the length of the wagon, whereby the
connecting rod E is rendered so much shorter.
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. The construction or arrangement of either side brake gear according to
which a vertical lever is fixed on the brake shaft upon which the levers are
mounted that connect with the push rods, said vertical lever being by a rod
connected to one arm of a bell crank lever fixed on a cross shaft the other
arm forming a handle for actuating the brake, a similar handle being fixed on
the other side of the wagon, suitable means being provided for disengaging the
hand lever or levers from the rack or racks from either side of the wagon
substantially as described and shewn.
2. The bow shaped construction or form of the operating handles, whereby a
feathering action can be conveniently obtained with a short handle.
