Improvements in Railway Platform Hand Trucks, Trollies, Perambu-
lators, and like Vehicles.
WILLIAM FREDERICK WOOD ELLIS, Engineer, 23, Waldemar Avenue, Fulham,
London, S.W. I do hereby declare the nature of this invention to be as
follows:-
My invention relates to the application of what is commonly termed a
scotch," to the front or back of wheels of trollies trucks & perambulators &c.
in order to automatically arrest or scotch immediately any further motion with
the utmost certainty, as soon as the trolly, truck or perambulator &c. is
released by the porter or attendant after pushing or pulling same by hand. The
manner in which I perform this is by the means of a rod or rods attatched to the
handle or any portion of the trolly perambulator truck &c. & such like vehicles,
which the porter or attendant generally takes hold of.
Attatched to this rod or rods. If a bell crank lever or levers, fixed on shaft or
studs fastened to the trucks.
Connected with these levers I attatch, an ordinary piece of wood or iron or other
material similarly to what is employed by the shunters porters or attendants in
the railway service for scotching stopping or arresting railway wagons. In
order that immediately the portion of the truck, trolly, perambulators & other
similar vehicles is released or let go by the porter or attendant the scotch through
the levers immediately drops & forces itself between the ground, floor or plat-
form thereby instantly bringing the trolly or truck, to a full stop & arresting
any further motion or travelling of the above said trolleys & other similar
vehicles. By employing the aforesaid scotch or kid I dispense entirely with the
ordinary friction breaks.
Another method which I employ consists in the application of hinged or move-
able legs or rods in such a manner that when the porter or attendant releases his
hold of the vehicles above mentioned the said legs or rods, fall to the ground or
floor & arrest any further travelling, motion, to the trucks trollies or perambu-
lators or similar vehicles.

I, WILLIAM FREDERICK WOOD ELLIS, late of 23, Waldemar Avenue, Fulham,
London, S.W., now of Queen's Chambers, 5, John Dalton Street, Manchester,
..

page_text: 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:-
"scotch"
My invention relates to the application of what is commonly termed a
to the front or back wheels of railway platform hand trucks, trollies, perambu-
lators and like vehicles, in order to automatically prevent or arrest immediately
any further motion of the vehicle, with the utmost certainty, as soon as the said
vehicle is released by the porter or attendant after pushing or pulling the same
by hand.
The manner in which my said invention is to be performed or carried into
practical effect will be readily understood on reference to the annexed two sheets
of drawings and the following explanation thereof.
On Sheet 1 of the drawings Fig. 1 is a side elevation and Fig. 2 an end view of
a railway platform hand truck with my invention shown as applied thereto, and
on Sheet 2 of the drawings Fig. 3 is a side elevation of a perambulator with my
invention shown as applied thereto, and Fig. 4 a side view of a railway platform
hand truck showing the application of a modification of my invention thereto.
For the purposes of my invention I attach to the handle A (or to any other
suitable portion of the truck, trolley, perambulator, or other like vehicle) which
the porter or attendant generally takes hold of, a cranked rod or rods B provided
with a double headed cam or tumbler B* acting against the upper end C of a
vertical rod D the lower end of which is attached to a bell crank lever E mounted
on shafts or studs carried by a bracket S fixed or fastened to the floor or frame P
of the truck or vehicle Q.
Connected to bell crank lever E by a rod F' is a second bell crank lever G which
is carried by a bracket R and is connected by toggle-jointed levers H, I, J, to
levers K, L swinging on the axles of the truck trolley or perambulator wheels
and provided at the lower extremities with shoes or wedge pieces M, N, of wood,
iron or other suitable material, similar to what are employed by the shunters,
porters or attendants in the railway service for "scotching" stopping, or arrest-
ing railway wagons.
The effect of this arrangement is that immediately the handle (or other portion)
of the truck trolley or perambulator) is released or let go by the porter or
attendant the "scotches" L, M, will by means of the toggle-jointed levers H, I,
acted upon by the spring or springs be immediately caused to drop and force
themselves between the rim or tyre of the wheels and the ground, floor, or plat-
form, thereby instantly bringing the truck or other vehicle to a full stop and
arresting any further motion or travelling of the above mentioned trucks or other
like vehicles.
It will be seen that according to my invention I do not employ any kind of
friction brake or blocks which are ordinarily used for such purposes.
Fig. 4 Sheet 2 shows a modification of my invention which consists in the
application of hinged or movable legs or levers T, U, in place of the shoes M, N,
which (instead of "scotching" the wheels) when the porter or attendant releases
his hands from the vehicle, will immediately fall down onto the ground or plat-
form and prevent or arrest any further motion of the truck, trolley, perambu-
lator or other like vehicle.
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 combination with the handle or other similar portion of a railway plat
form hand truck, trolley, perambulator, or like vehicle, of shoes wedges or
scotches acting between the rims or tyres of the wheels and the ground or
platform the said handle or other similar portion being so connected by levers
and rods to the said shoes, wedges, or scotches that whenever the porter or
attendant releases the said handle the shoe wedges or scotches are automatically
ndant

page_text: forced in between the ground or platform and the periphery of the wheels; and
as soon as the said porter or attendant commences to either pull or push the said
handle the said shoe wedges or scotches are by the motion of the handle automati-
cally withdrawn substantially as hereinbefore described and illustrated by
Figs. 1, 2 and 3 of the drawings annexed, and
Secondly. The combination with the handle or other similar portion of such
vehicles of legs or props with their lower ends acting automatically against the
ground or platform, the handle or similar portion of the vehicle being so con-
nected by levers and rods to such legs or props that whenever the porter or
attendant releases the handle or other similar portion the said legs or props will
automatically fall down and come into contact with the ground or platform and
thus arrest the further motion of the vehicle, and as soon as the said porter or
attendant commences either to pull or push the truck or vehicle the said hinged
legs or props will by the motion of the handle be automatically raised up out of
contact with the ground or platform, substantially as bereinbefore described and
illustrated by Fig. of the annexed drawings.
