Improvements in Wheelbarrows.
We WILLIAM CHRISTOPHER BARNS Tank Manufacturer and JOHN COCKBURN
Barrow Maker both of Tank Works, Westferry Road, Millwall in the County of
Middlesex do hereby declare the nature of this invention to be as follows:-
Our invention is more particularly applicable to metal wheelbarrows and has for its
object to relieve the driver from sustaining the weight of the load in the barrow and
also to induce the easy travel of the driving wheel thereof. To effect this we fit the
bottom of the barrow with crank bearings wherein we mount a driving wheel of
large diameter (say, about 18"), and place the same nearer to the handles than here-
tofore. By so doing we convert the wheel into a support which serves to relieve
the driver's hands from the strain of the load, while owing to the large diameter of
the wheel, and its position on the barrow it revolves easily. This arises from the
fact that the barrow is not tilted so much while being driven as when it is fitted
with an ordinary small wheel, whereby the weight of the load is prevented from
being pitched forward and acting as a drag on the wheel.
In order to allow the wheel to rotate freely a recess is formed in the body of the
barrow wherein at each revolution of the wheel the upper portion of its periphery
rotates. This recess projects into the body of the barrow and is of a taper form
so as to obviate its materially diminishing the containing capacity of the barrow.

Improvements in Wheelbarrows.
We WILLIAM CHRISTOPHER BARNS Tank Manufacturer and JOHN COCKBURN,
Barrow Maker both of Tank Works, Westferry Road Millwall in the County of
Middlesex 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 :-
Our invention is more particularly applicable to metal wheel barrows, and has for
its object to materially diminish the strain on the driver created by the weight of the
load in the barrow, and also to induce the easy travel of the driving wheel thereof.
To effect this we fit the bottom of the barrow with crank or other suitable bearings
wherein we mount an ordinary large diameter driving wheel (say, about 18" in
diameter); taking care to place the same nearer to the handles than heretofore in
any convenient position. By so doing we convert such wheel into a support which
serves to relieve the driver's hands from the strain of the load, while owing to the
large diameter of the wheel, and its position on the barrow, it revolves easily. This
arises from the fact that the barrow is not tilted so much while being driven as
when it is fitted with an ordinary small wheel, whereby the weight of the load is
prevented from being pitched forward, and acting as a drag on the wheel.
In order to allow the wheel to rotate freely, and likewise to facilitate mounting
the wheel nearer the handles as previously mentioned, a suitably shaped recess is
formed in the body of the barrow in any convenient position; wherein at each
revolution of the wheel the upper portion of its periphery rotates.
This recess
projects into the body of the barrow, and is preferably made of a taper form so as
DO

page_text: to obviate its materially diminishing the containing capacity of the barrow: and
also when tipping the barrow to discharge the load, to prevent any portion of such
load being retained therein. Such recess may either be cast in the barrow, or it
may consist of a metal casing inserted through a suitable opening made in the body
of the barrow and rivetted or otherwise secured thereto.
In the accompanying drawings similar letters of reference indicate corresponding
parts.
Figure 1 shews in side elevation a barrow constructed according to our invention.
A portion of one side of the barrow is shewn removed, in order to shew the casing
formed or inserted in the body to make the recess above described.
Figure 2 is a transverse section in front elevation of such barrow, shewing the
taper form of such casing.
A is the body of the barrow. B the driving wheel mounted in crank bearings b.
C is a metal casing fitted in the body of the barrow and rivetted or otherwise
fastened thereto.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
1. In a wheel barrow, mounting a wheel of any suitable diameter therein in any
convenient position near to the handles thereof, so that such wheel takes the weight
of the load, and at the same time maintains an easy travel, all substantially as
herein before described and shewn.
2. Forming a suitable recess in the body of a wheel barrow, to allow such
wheel to revolve freely therein all substantially as hereinbefore described and
shewn.
3. In a wheel barrow the combination of a wheel of any suitable diameter
mounted near the handles of the barrow with a suitable recess all substantially as
hereinbefore described and shewn.
4. As a new article of manufacture a wheel barrow having a suitable recess
formed in the body thereof and a wheel of any suitable diameter mounted therein
in any convenient position near to the handles thereof all substantially as herein-
before described and shewn.
