PROVISIONAL SPECIFICATION.
Improvements in or relating to Luggage Trolleys and the like
Vehicles.
I, HARRY THOMSETT, S, Millstone Lane, Leicester, Accountant, do hereby
declare the nature of this invention to be as follows:-
1
This invention has reference more particularly to trolleys such as are used in
railway stations for conveying parcels and passengers luggage from one part of
the station to another.
The object of the invention is to construct such trolleys in such a manner that
the wheels are normally locked or braked against movement when the trolley
is not in use or being actually wheeled and that the brake must be positively
and intentionally taken off the wheels before the trolley can be moved from one
place to another.
According to the present invention the handle is preferably utilised as the
medium by which the brake can be taken off the wheels.
The braking may be effected in several ways.
According to one construction bolts or sliders are carried in guide bearings
on the axle tree and are maintained normally projecting through the usual open-
ings or spokes in the wheels so as to prevent them revolving.
These sliders may, to permit the wheels to rotate, be withdrawn by means of
a slide or equivalent actuated by depressing somewhat the handle of the trolley.
The said sliders may also if desired, be arranged to press against the side or
rim of the wheel or if it be preferred to brake the periphery of the wheels, a
brake shoe may be fixed to the end of a rod, bar or arm, pivotted to the axle tree
and moved on its centre, so as to take the brake shoe off the wheel, by the slide
and the handle as hereinbefore described or equivalent means.
The details of construction may be varied in the following and other respects
within the main lines of the invention. For instance the wheel locking sliders
may b kept in their locking position by means of suitable springs or as an
alternative they may be connected to the slide or an attachment thereto so as
to be movable positively therewith.
According to the foregoing construction a luggage trolley is always braked
and secured against accidental movement and indeed must be positively unbraked
before it can be used for carrying purposes.
The invention is also applicable to other types of trolleys or handtrucks than
those hereinbefore referred to.

Vehicles.
I, HARRY THOMSETT, 8, Millstone Lane, Leicester, Accountant, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to luggage trolleys and like vehicles and embodies im-
provements which are chiefly though not exclusively applicable to railway plat-
form trolleys used for conveying parcels and passengers' luggage from one part
of the station to another.
The object of the invention is to construct such trolleys in such a manner so that
the wheels are normally locked or braked against movement when the trolley
is not in use or being actually wheeled and that the brake must be positively
and intentionally taken off the wheels before the trolley can be moved from one
place to another.
According to this invention the brake mechanism is maintained normally
automatically in contact with the wheels of the trolley so as to hold or lock the
said wheels against movement and the handle of the trolley is utilized as the
medium by which the brake is taken off the wheels, suitable means or connections
being interposed between the handle and the brake for that purpose.
In order that the invention may be fully understood reference is made to the
accompanying drawings and the following description in reference thereto.
Only so much of a luggage trolley is shown in the drawings as is necessary to
illustrate the invention.
Figure 1 is a perspective view of the bogie or axle tree to which the front
wheels of a luggage trolley are connected, the bogie and handle of the trolley
being turned up or partly inverted to show the mechanism thereunder.
Figure 2 is an underneath plan of same.
Figure 3 is a similar view of a modification.
Figure 4 is a detail section of the bogie, slide and spring controlling the
latter.
Similar letters of reference indicate corresponding parts throughout the figures.
A, represents the bogie or swivelling frame or axle tree of a railway luggage
or platform trolley the front wheels 13 of which are carried one at each end
thereof.
On the underside of the bogie are two bolts or sliders C carried in guides or
staples C screwed to the underside of the bogie.
These bolts or sliders are maintained normally projecting through holes B¹
in the sides of the wheels so that when the trolley is not in use the wheels are
locked thereby against movement.
A slide D movable in a direction transverse to that of the movement of the
wheel locking sliders is interposed between the latter and is of such a width
that when in its normal position as shown in Figure 1 it keeps the sliders pro-
jecting through the holes in the wheels.
The said slide has two inwardly directed or inclined faces 11 leading to a neck
and is hinged at D2 and movably carried in guides D³ bolted to a block A¹ attached
to the axle tree A and to which the usual handle E of the trolley is also hinged
at E in the usual manner.
A strong flat steel spring F screwed at F1 Figure 4 to the bogie A bears
against the end of the slide D) so that its greatest width is normally located

page_text: between the sliders C to keep them projecting through the openings in the
wheels and the other end of the said slide is located up against a block Ea
screwed to, or a shoulder formed on, the trolley handle from which the slide re-
ceives its movement.
The strength of the spring F is arranged to keep the slide in the position
indicated in Figure 1 even against the weight or pressure of the handle when the
latter is allowed to rest thereon.
A coiled spring G, having one end connected to each of the sliders C, keeps
the latter pressing against the slide 1) so that the said sliders becomes with-
drawn when the inclined faces D¹ of the slides are moved past them.
Instead of a single spring for the two sliders a separate spring may be con-
nected to each slider, one end of the spring being fastened to the latter and
the other end to the bogie.
In the event of one spring becoming detached or defective the other would
be in operation and thus the brake would not become defective.
The operation of the brake is as follows::
When the trolley is not in use the handle is raised or turned up in the well
understood manner and the brake mechanism is in the operative position indi-
cated in Figure 1, the locking sliders projecting through the openings in the
wheels, thereby locking the latter against movement.
Upon a porter or attendant taking hold and lowering the handle for the pur-
pose of wheeling the trolley the downward pressure exerted by him on the handle
will cause the block E2 to move the slide 1) forward in its bearings to overcome
the pressure of the spring F whereupon the spring G will draw the sliders C
towards each other and cause them to follow the inclined sides D¹ of the slide
into the neck and in so doing withdraw their opposite ends from the holes in the
wheels as indicated in Figure 2. The wheels are then free to revolve.
In trolleys having wheels with a non-perforated or solid centre or sides so
that the openings B are not present, a brake shoe or block of any suitable con-
struction may be fitted on to the ends of the sliders so as to brake the sides of
such wheels as will be readily understood.
In the modification shown in Figure 3 the brake is constructed to act on the
periphery of the wheels when the trolley is not in use and the handle is in its
raised position.
Brake shoes or blocks H. bearing on the circumference of the wheels are carried
on the ends of levers fulcrummed at H* to a plate or bracket J on the underside
of the axle tree A and attached by a pin and slot connection K to a slide D*
(similar to D but having no neck) movable in guides D3 and actuated through
the medium of the handle E in the manner herein before described with reference
to Figures 1 and 2.
A flat spring F bearing against the end of the slide 1 pushes the latter into
the position shown so as to cause each lever H¹ to keep its brake shoe normally
pressing against and locking its wheel against movement.
'pon the handle being lowered as when a porter is about to pull or push the
trolley the slide and levers will be moved into the positions shown by the dotted
lines so that the brake shoes are taken off the wheels.
Instead of the flat spring by which both brake shoes are kept applied to the
wheels, or if desired in addition thereto, a coiled spring L attached one end to
the lever and the other end to the bogie may be employed for that purpose.
In
this case each brake shoe would be kept in operative position by a separate
spring.
Platform luggage trolleys differ somewhat in construction, but it will be
found that in most cases the handle can be made the medium by which the brake
shoes can by suitable interposed mechanism be taken off the wheels. It is
obvious that such interposed mechanism may be varied within the skill of the
mechanic rendered requisite according to the varying details of construction
of platform trolleys but without departing from the main lines of the invention.
