I, GUY ERNEST LLOYD, of 2 Rowland Street, Rugby, in the County of Warwick,
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to arrest the vehicle when its handle is released.
According to one arrangement the body of the vehicle carries a brake block
which when the handle is released is pressed by the weight of the vehicle and
its load into contact with the wheel or the ground. On lifting or pulling the
handle however the body of the vehicle is raised and the brake is taken off.
This lifting of the body may be done in various ways such as by connecting it to
the axle by a toggle or other lever or an eccentric or cam operated by the handle
and I prefer to arrange the mechanism so that the effort involved in raising the
body has not to be sustained when the handle is in position for pulling or pushing
the truck.
If a spring is interposed between the body of the vehicle and the axle, I
arrange that the brake block and raising mechanism is attached to the lower part
of the spring so that the movement of the brake block relatively to the wheel
shall depend only on the position of the handle, and be unaffected by the defor-
mation of the spring.
According to another arrangement, I employ (as has before been suggested) a
ratchet wheel fixed to or forming part of one of the carrying wheels, and a
pawl carried or actuated by the handle; but I so arrange the ratchet wheel and
pawl that they gradually stop the vehicle before positively coming into gear so
that the great strain caused by suddenly arresting the vehicle is avoided. This is
done by rounding the nose of the pawl so that unless it is fully home it rides up
the teeth of the ratchet wheel. The teeth of the ratchet wheel are preferably
pins projecting from a disc or formed by holes in it, or they may be the spokes of
the wheel.

formed to be particularly described and ascertained in and by the following
statement:
The object of this invention is to arrest the vehicle when its handle is released.
According to one arrangement the body of the vehicle carries a brake block
which when the handle is released is pressed by the weight of the vehicle and
its load into contact with the wheel or the ground. On lifting or pulling the
handle however the body of the vehicle is raised and the brake is taken off.
This lifting of the body may be done in various ways such as by connecting it to
the axle by a toggle or other lever or an eccentric or cam operated by the handle
and I prefer to arrange the mechanism so that the effort involved in raising the
body has not to be sustained when the handle is in position for pulling or pushing
the truck.
If a spring is interposed between the body of the vehicle and the axle, I
arrange that the brake block and raising mechanism is attached to the lower part
of the spring so that the movement of the brake block relatively to the wheel
shall depend only on the position of the handle, and be unaffected by the defor-
mation of the spring.
According to another arrangement I employ (as has before been suggested) a
ratchet wheel fixed to or forming part of one of the carrying wheels, and a
pawl carried or actuated by the handle, but I so arrange the ratchet wheel and
pawl that they gradually stop the vehicle before positively coming into gear so
that the great strain caused by suddenly arresting the vehicle is avoided. This is
done by rounding the nose of the pawl so that unless it is fully home it rides up
the teeth of the ratchet wheel. The teeth of the ratchet wheel are preferably
pins projecting from a disc or formed by holes in it, or they may be the spokes of
the wheel.
Figures 1 to 4 show the application of my invention to the front axle of a low
platform lorry with small wheels and a handle which when out of use can either
lie on the ground or bear against the body. Figures 1 and 2 are side elevations
(with one of the front wheels removed). Figure 3 is a plan and Figure 4 a front
elevation. In Figure 2 the handle is released and the brake is in action whilst in
Figures 1, 3 and 4 the brake is off.
The front of the platform a of the lorry is supported on a turntable 6 carried by a
transverse beam c. d is an arm fixed to the middle of the beam c and having
the handle e pivotted to it. The front axle f has bolted to it an arm g and a pair
of hooked armis h. j are castings, bolted to the ends of the beam c, the outer
ends of which form brake blocks and projecting downwards from them are
webs engaging with the hooks h.
In Figures 1, 3 and 4 the tail end of the handle e is pressing the arm g down-
wards thereby slightly turning the axle and raising the arms so that the front
of the body is raised and the brake blocks are lifted off the wheels. In
Figure 2 the handle e is clear of the arm g and the whole weight of the front
of the platform we therefore rests on the brake blocks k.
In order to provide a simple means of adjusting the arms on the axle so that
cach brake leaves its wheel at the same angle of the axle I form a ridge in the
under face of the arms where they rest on the axle so that they may be fixed
at different angles relatively to the latter by suitably screwing up the bolts on the
two sides. This means also provides an adjustment for both arms together
relatively to the middle arm g. A tension spring between and the frame
may be added to increase, or a compression spring to decrease the brake-power.
Figures 5 and 6 are similar views to Figures 1 and and shew the application
to the front axle of a high trolley having large wheels and an entirely different
type of handle. Figure 5 shews the brake off, and Figure 6 shews it on. In this
case the arm is raised with the handle, the arms are therefore placed on the

page_text: same side of the axle as g. The link m is pivoted at à to the handle at a point
which is near the dead centre when the handle is in use.
A tension spring may be fitted between y and the arm d to decrease, or a com-
pression spring to increase the brake-power.
In the foregoing cases, the whole appliance is self-contained on the fore carriage,
and turns with it. If there are springs between the frame and axle, these rest
on the castings as shewn in Figure which illustrates a truck which ordinarily
has no handles, fixed or otherwise, and to which handles have to be added to
carry out my invention. Two arrangements are shewn, which are alternative or
may be used together. The arrangement for the axle (from which the near wheel
is shewn removed) is similar to those already described, the army being connected
by the link m directly to the handle e which when out of use lies away from
the truck as shewn, but when in use is pushed up to the truck; this handle is
designed to withstand the racking effort necessary to steer the truck from this
end. At the swivel end is shewn another type of handle o suitable for leaning
upon. A bracket prests either directly or through the usual helical spring, if
the truck is so fitted, upon a frame g, which is free to slide up and down on the
truck and carries at its lower end a ring brake r which can bear on the wheel
rim at all positions of the swivel, or can cause a brake in the swivel to do so.
At the upper end of q is the handle having a link s resting on the top of the
spindle of the fork carrying the wheel. When is depressed it raises the
frame relatively to the spindlet and so keeps the ring brake off the wheel. If
the truck is not furnished with springs the handle and ring brake are fixed to the
body of the truck. Springs may be fitted to return the handles to their outward
positions when released. Although the two brakes shewn in Figure 7 are intended
as alternatives, two handles so connected as to move together are a necessity if
the truck is to be used from either end indifferently. The motion of o is shewn as
transmitted to by light tension rods and an incline u, which takes the place of a
bell crank.
Figure 8 shews a mode of applying my invention to the rear axle of a trolley
of the type shewn in Figures 1 to 6, either in place of or in addition to its
application to the front axle. The rear axle is fitted with arms and the body of
the trolley with brakes in a manner similar to that shewn in Figure 7, except
that in the case illustrated the trolley has no springs. The link m receives its
motion from an incline on a spindle working up and down within the hollow
centre pin of the fore-carriage. The lower end of the centre spindle is raised
by a lever from the handle e in all positions of the fore-carriage, with which v
does not revolve. On the lever being released, the spindle is free to drop
and allows the link m to recede so that the brakes may rest on the wheel rims.
Figure 9 shews one mode of application of my second arrangement of a ratchet
wheel and a pawl having a rounded nose. The front wheel or wheels have pins &
on them with which the pawl y connected by the links to the handle e engages.
The pawl can just enter the space between two of the pins, and being rounded
does not do so fully until the motion is slow, but partially enters one space and is
forced out to enter the next, and so on. Where the wheel has spokes or holes in
the web, I arrange a suitable pawl to work at right angles to the plane of the
wheel, to enter the spaces between the spokes or the holes as the case may be.
Both my arrangements have the advantage that the truck can be partially braked
when taken down a steep slope.
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 a truck or other vehicle of a brake put on by the
weight of the vehicle and taken off by the handle when in use.
2. The combination with a truck or other vehicle, of a ratchet wheel turning
with the carrying wheels and a pawl put into and out of gear by the handle, the

page_text: ratchet wheel and pawl being so formed that the former is gradually checked and
finally stopped by the latter.
3. Trucks and other vehicles substantially as described and illustrated in the
drawings.
