Improvements in Platform Trolleys.
Year: 1898

page_text: I, ALEXANDER MEIN, of Hope Ironworks, Station Street, Stratford, Essex,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to trolley trucks used on railway platforms for the
transport of passengers luggage.
According to this invention the two back wheels are carried on a cross axle,
the journal ends of which are held in a suitable bearing in pendant brackets from
underside of frame. Secured on the axle near one of the wheels or to the wheel
itself is a brake drum for a band brake operated from other end of trolley by
outside vertical pivotted lever, the lower end of which is connected to the band
by levers and links. The upper part of lever under the handle is held in a
spring guide which presses it into a recess at one end to secure it when the
lever is sufficiently moved to put on brake. To take off brake the lever is pressed
out of the recess and moved back. The movement of the spring guide is or
may be controlled by a lock nut. The front wheels are arranged to be carried
each on a swing fork arm under the frame so that the wheels do not project out
beyond the front. The swing arm is carried in a vertical bush by a right angle
stem which is prevented coming out by a set screw, and groove: The bush is
carried by cross supports attached to part of frame of trolley. A hole is made in
top of bush and through floor for oil.

Improvements in Platform Trolleys.
I, ALEXANDER MEIN, of Hope Iron Works, Station Street, Stratford, Essex,
Engineer, 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 trolley trucks used on railway platforms for the
transport of luggage or baggage generally, from place to place, the invention
comprising an improved construction and combination of parts comprising such
trucks.
In order that such construction and combination of parts may be readily
understood, I will describe same with reference to the accompanying drawings,

page_text: whereon Fig. 1, shews in side view, the two ends of a trolley constructed
according to my invention, the front part, on the right hand side of the drawing
being in section. Fig. 2 shews in inverted plan of those parts of the trolley
as in Fig. 1. At Fig. 3 on the left hand side, is a half end elevation of what I
call the front end of the trolley, that on the right hand side being a half
transverse section, taken from the rear end of the trolley. Fig. 4, is a horizontal
section taken on the line X Y of Fig. 3 to shew means for holding a brake lever,
hereafter described.
The body of the trolley may be constructed in any desired form and may
consist for example, of a frame work A, to carry flooring A', longitudinal
side frames A2 and ends A³. According to this invention two rear wheels B, B,
are carried on a cross axle C, the journal ends of which are held in suitable
bearings in pendant brackets 1), fixed to the underside of the frame A.
Secured to the axle C, near one of the wheels B, or as shewn, formed with one of
the wheels, is a brake drum B'₁, partly encircling which is a band brake E, one
end of which is fixed to the under frame A, of the trolley, while the other end is
carried by one arm of a lever F. The lever F, is pivotted at F¹, on to a strap A*,
fixed to the frame A, and the second opposite arm of the lever F is jointed to
a rod G extending under the bottom of the trolley towards the front and it is by
a pull upon this rod that the lever F, is rocked and the brake applied to the
brake drum B. What I term, for the purposes of this description, the front end
of the rod G, is jointed to one arm of a bell crank lever G', pivotted at G2, to a
etrap A, on the frame work of the trolley and the end of the second arm of the
hell crank G¹, is connected by a part H, to a hand lever J, Figs. 1 and 3, by which
the brake is operated the hand lever J, being pivotted to the frame A, at J,
and so that a lateral motion of the lever J, relatively to the trolley will operate
the bell crank G¹ and apply the brake.
In order to control the position of the hand lever J, and to retain same, I
provide a spring retaining device. Such a device, Figs. 3 and 4, may conveniently
consist of a spring K, fixed to the end frame A³, and adapted to hold the hand
lever J, against a plate L, on the end frame, throughout the whole stroke of the
said lever. Upon the face of the hand lever, next the plate L, I provide a pro-
jecting stud J³, which works in a curved inclined recess L', in the plate L, and
near one end of the plate L, I form a hole L2, to receive the stud J. With such
an arrangement the hand lever may be rocked on its centre J¹, the pin Ja, will
slide up the recess L', the spring K, will be forced outwards, and when the hand
lever J, has reached the extent of its travel and the brake is applied the pin J³,
will enter the aperture L2, and will be held there by the spring K, until released
by the attendant.
The front wheels M, Figs. 1 and 2, are arranged to be carried each on a swing
arm M, under the frame A, so that the wheels do not project beyond the front of
the trolley. Each swing arm M¹, is carried in a vertical bush N, Fig. 1, by a
right angle stem, which is maintained therein by a set screw in the bush entering
an annular groove in the stem. The bush N, is carried by cross supports N'
attached to the frame of the trolley and a hole is made through the top of the
bush and the floor of the car to admit oil.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is―
1. A trolley for use on railway platforms and other places, for the transport of
luggage or baggage generally from place to place, the combination of two inde-
pendant pivottedly mounted front wheels, two rear wheels fixed on
a axle
extending transversely of the trolley and carried in bearing thereon, a brake
drum on the transverse axle, a band brake to act on the drum, links and levers
connecting the brake to a hand lever and means for retaining the hand lever
when the brake is applied substantially as described.

page_text: 2. The construction, arrangement and combination of parts, composing my
improved trolley substantially as and for the purposes described with reference
to the accompanying drawings.
