A Combined Self-acting Brake and Handle for Railway Trollies and
other Vehicles.
I, RICILARD ALFRED SMITH, of 23, Barnmead Road, Beckenham, Kent, Gentle-
man, do hereby declare the nature of this invention to be as follows;-
This invention relates to a combined self-acting brake and handle for railway
trollies and other vehicles and has for its object to provide a means whereby one
or more wheels of the vehicle to which the brake is applied may be prevented
from revolving when the vehicle is not being pushed or drawn along, thereby
insuring the immediate stoppage of such vehicle when the pressure is removed
from the handle thereof.
In carrying the invention into effect, I may attach to the spindle of one pair
of wheels at any convenient point between the said wheels a disc of suitable
width having formed in its periphery a number of notches or recesses with one
of which is normally engaged a dog or tooth formed upon the underside of a
lever or arm pivotted at any convenient point between its ends to a suitable
bracket attached to the body of the vehicle and having at its outer end an
adjustable counterweight. The opposite end of the lever is pivotally attached to
the lower end of a vertical rod or other equivalent means, the upper end of
which is provided with a cross bar which bar also forms the handle to be held
whilst propelling the vehicle. The lever aforesaid may be held in position so
that the dog or tooth thereon shall engage with one of the recesses in the disc
by means of a spiral or other suitable spring, one end of the spring being attached
to the lever and the other to the underside of the body of the vehicle in such
a position with regard to its centre of rotation, that the weighted end shall always
have a tendency to fall directly the pressure upon the handle bar is removed.
In the case of the wheels being freely mounted upon their spindles I attach
a plate or disc to one face of the wheel and provide two weighted levers with
dogs or teeth as aforesaid, which are operated in the same manner as in the
previous case.
Suitable guides may be provided for the vertical rods or the like, to which the
handle is attached and a cage or basket of wire work or other material may be
provided to prevent the luggage, in the case of a trolley, from interfering with
the movement of the handle.

I, RICILARD ALFRED SMITH, of 23, Barnmead Road, Beckenham, Kent, Gentle-
man, 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 a self-acting brake for railway trollies and other
vehicles and has for its object to provide a means whereby one or more wheels of
the vehicle to which the brake is applied may be prevented from revolving when
the vehicle is not being pushed or drawn along, thereby ensuring the immediate
stoppage of Euch vehicle when the pressure is removed from the handle thereof.
In order that the invention may be the better understood drawings are appended 1
in which:-
Fig. 1, is a side elevational view of a trolley to which my invention has been
applied.
Fig. 2, is an end view thereof.
Fig. 3, is an enlarged side elevational view of an alternative arrangement of 1
the device for locking the wheels.
Fig. 4, is a front elevation of Fig. 3.
A, is the body of the trolley which in the present case is illustrated as having
four wheels, two of which B, B, are freely mounted upon the transverse axle C,
supported by the brackets 1), D, attached in any suitable manner to the underside:
of the body of the trolley. Attached to or cast integral with the wheels B, on
one face of either or both of the wheels, as may be found desirable, is a disc
annulus or ring E, upon the periphery of which are cut or otherwise formed a
number of notches or recesses F. Normally engaged with one of the recesses F,
is a tooth or projection G, projecting vertically downwards from the underside of
the lever H. The lever H, is pivotted at I, to the bracket J, and is pivotally
connected at its outer end to the rod K, the opposite or inner end of the lever
working in the guide L. To keep the lever H, always bearing upon the disc E,
a spring M, may be provided at one end of the said lever and at the other an
adjustable weight N, but I may in practice find the weight of the lever H, in
itself suflicient for all practical purposes in which case the weight or spring or
both may be dispensed with.
The rod K, aforesaid is led upwards through the body of the trolley and through
the cross bar U, and terminates in a horizontal bar P, for which guides Q, are
provided, the said guides passing through the bar P, and being attached at
their lower ends to the bar O, and at their upper ends to rod R, to which may
be attached the guard S, of wire netting or the like designed to prevent the
packages or luggage upon the trolley from interfering with the free movement of
the bar P. It will be seen from the foregoing description that so long as the
bar P, is not depressed, the tooth G, will remain engaged with one of the recessos F,
thereby preventing the revolution of the wheels B, B, but that when it is desired
to move the trolley the bar P, may be depressed and the end of the lever being
depressed with it will lift the tooth clear of the disc until the bar is released.
In the case where the wheels are securely fixed to a transverse spindle only
one set of the parts before enumerated would be necessary and a notched
disc T, shown in Figs. 3 and 4 would be secured to the axle preferably at
or near the centre of its length, the arrangement of the lover and actuating bar
and rod secured thereto being the same, the rod, however, in this case being placed

page_text: at or near the centre of the bar P. It is obvious that the lever or levers H,
as the case may be, can be operated from either end of the trolley, any known
system of levers being employed to actuate the same, and also that the device
may be applied to any other form of trolley than that shown, the essential portions
thereof being easily adapted to suit the various forms of trollies and other vehicles
upon which such a brake could be employed. Instead of forming a projection
upon the lever I may cut a recess therein which shall engage with teeth formed
upon the periphery of the disco E.
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 improved brake for trollies and other vehicles consisting of a disc pro-
vided with peripheral notches or recesses, secured either to the axle of the wheel
or wheels, or to the face of the wheel itself and so arranged that a tooth or pro-
jection upon a lever shall be normally engaged with one of the recesses in the
said disc to prevent the revolution of the wheels until the said tooth is withdrawn
from its engagement with the recess, which may be offected by depressing a suit-
able bar secured to a rod attached to the end of the said lever or by any other
convenient means.
2. The improved brake for trollies and other vehicles constructed, arranged and
operating substantially as herein described and illustrated by the appended
drawings.
