THOMAS DREW, 90, Bridge Street, Burdett Road, Bow, E., Sign Writer, do
hereby declare the nature of this invention to be as follows:-
This brake is for one wheel and can be attached to a three or four wheel
barrow.
It consists of a tube with a nut on the top end. At bottom end is a fork
bent to suit wheel to work in. It is attached to the barrows by means of two
brackets, one fixed on top rail and one on bottom rail. Inside this tube is a
spindle with a knuckle joint and a knob at top end. At the bottom end is a
fork dropping each side of the wheel. This wheel has five lugs each side. When
the barrow is not in use bend the joint and the spindle and fork drops over the
wheel between the lugs and thus forms a brake. When to be used lift the knob
to the joint and it will bend over, thus raising the spindle and fork off the wheel
releasing the same. The whole is to work round in the brackets forming guide
wheel.
Improved Locking Brake for Platform Goods Barrows.
I, THOMAS DREW, formerly of No. 90, Bridge Street, Burdett Road, Bow, in
the County of Middlesex, but at present residing at No. 60, Salisbury Road,
Manor Park, in the County of Essex, Sign Writer, do hereby declare the nature
of my said invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement:-
―
My said invention relates to an improved locking brake for platform goods
barrows.
It is well known that a goods barrow left on a railway platform unattended
is liable to be set in motion by a gust of wind or by a wind current created by a
passing train or by other causes and several serious accidents have been caused
by barrows running on to the permanent way.
Now, the object of the present invention is to provide simple and inexpensive
means whereby one of the wheels of the barrow may be readily locked against
rotation so that the barrow may be left unattended with perfect safety.
In carrying the invention into effect, the stem of the fork or the vertical axle
of the caster wheel or one of the caster wheels of the trunk as the case may be,
is formed tubular and is mounted with capability of revolution in bearings
077

page_text: provided in straps or brackets fixed to the top and bottom rails, or, in cases where
three rails are employed to the centre and bottom rails, of the frame of the
barrow, a collar or flange at the lower part and a nut at the upper part prevent-
ing endway movement of the axle.
Mounted with capability of longitudinal movement within the tubular axle
but fixed against rotation with relation thereto is a spindle which near to its
upper end is provided with a knuckle joint and at its upper end is furnished
with a knob or handle by the aid of which it may be raised at the times desired
whilst the lower end of the spindle is formed with a fork which is adapted to
drop over or embrace the wheel.
The wheel is provided with several laterally projecting lugs or studs with
which the fork of the spindle co-acts to lock the wheel against revolution at the
desired times whilst when it is required to take off the brake or unlock the wheel
the spindle is by means of the knob raised until the knuckle is above the upper
end of the vertical axle and the upper part of the spindle with the knob is turned
at right angles with the lower part thereby holding the brake off or out of
action.
And, in order that the said invention may be more clearly understood and
readily carried into effect, I will proceed, aided by the accompanying drawings,
more fully to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a perspective view of a platform luggage barrow having the present
invention applied thereto and showing the brake on.
Figure 2, is a front elevation of part thereof.
Figure 3, is a vertical section taken on the line 1-1 of Figure 2.
Figure 4 is a similar view to Figure 2, but showing the brake off, and,
Figure 5 is a similar view to Figure 2, illustrating a slight modification.
In the several figures, in which like parts are indicated by similar letters of
reference, Figures 2, to 5, are drawn to an increased scale with respect to
Figure 1.
Referring to Figures 1, to 4, a represents the frame or body of the barrow,
a, a, represent respectively the top and bottom rails of the end thereof, b repre-
sents the ordinary carrying wheels, and c, c*, represent the caster or trailing
wheels.
The horizontal axles c', of the caster wheels c, c* are carried by the bifurcated
bent or cranked lower ends d', of vertical axles d, d*, which are mounted with
capability of revolution in bearings provided in straps or brackets a", fixed
respectively to the top and bottom rails a¹, a², of the frame of the barrow, collars
or flanges, at the lower parts and nuts d³, screwed upon the threaded upper
ends of the vertical axles d, d*, preventing endway movement thereof.
The vertical axle *, of the caster wheel c*, is formed tubular and mounted
within the same is a spindle e, which is formed square in cross section, or it
might be otherwise suitably formed to prevent independent rotation, and passes
through a correspondingly shaped hole formed in the fitting 2*, and is thus
compelled to turn with the axle d*, whilst being capable of vertical movement
independently thereof.
The spindle e, at its lower end is formed with a fork e¹, which is adapted to
drop over or embrace the wheel c*, and near to its upper end it is provided with
a knuckle joint c², which in addition to the purpose hereinafter named serves to
guide the spindle e, within the tubular axle *, whilst at its upper end the
spindle e, is furnished with a knob or handle e, by the aid of which it may be
manipulated.
The wheel e, is provided with several laterally projecting lugs or studs,
with which the fork e¹, of the spindle e, co-acts to lock the wheel c*, against
revolution at the desired times as shown at Figures 1, to 3, whilst when it its
desired to take off the brake and unlock the wheel the spindle e, is by means of

page_text: the knob or handle 3, raised until the knuckle e², is above the upper end of the
vertical axle d*, and the upper end of the spindle c, with the knob or handle e
is then turned at right angles with the lower part thereof as shown at Figure 4,
thereby holding the fork e', raised clear of the studs &, and the brake off and
out of action.
In order to again put the brake on, it is merely necessary to raise the knob or
handle, into its vertical position when the spindle e, will descend by gravity,
assisted if desired by a spring, and throw the fork c', into engagement with the
studs or projections c².
In the example given at Figure 5, the device is substantially the same as that
herein before shown and described but in this case the knuckle joint is dispensed
with and the knob is substituted by a lever handle e, mounted upon an axis of
motion at e, upon the upper rail, and which at one end is provided with a
slot, which engages a pin 2, on the spindle e, and at the other end is adapted
to be depressed by the hand of a person wheeling the barrow by which arrange-
ment the fork e', will be raised as shown by the dotted lines and the brake taken
off whilst the barrow is being moved along but upon the attendant leaving the
same the weight of the parts, aided if desired by a spring, will cause the fork c',
to descend into engagement with the studs c², of the wheel c*, thus automatically
locking the latter against movement.
Although the invention is herein shown and described as applied to a four
wheeled barrow it will be obvious that it is equally applicable to barrows having
a larger or smaller number of wheels than that above named.
By the means herein before described, a simple and inexpensive brake is
obtained which is adapted to be applied to all existing barrows and which will
effectually prevent the unintentional movement thereof and thereby obviate the
dangers herein before pointed out.
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. A brake for platform barrows comprising one or more laterally projecting
studs upon one of the wheels and a vertically movement spindle adapted to engage
said studs, substantially as herein shown and described.'
2. A brake for platform barrows comprising a tubular vertical axle to one of
the caster wheels, a spindle passing through said axle with capability of vertical
movement but held against independent rotation, a fork or projection upon the
lower end of said spindle, co-acting laterally arranged studs or the like upon the
wheel and means for manipulating the same and retaining it in its raised position
at the times desired, substantially as herein shown and described.
3. A brake for platform barrows comprising a tubular vertical axle to one of
the caster wheels, a spindle passing through said axle with capability of vertical
movement but held against independent rotation, a fork upon the lower end of
said spindle adapted to embrace the wheel, co-acting laterally projecting studs
upon the wheel, a knuckle joint in the spindle near to its upper part and a
manipulating handle, substantially as herein shown and described.
