IMPROVED CART WITH A REVOLVING AXLE
Year: 1884

page_text: I, SAINT JOHN VINCENT DAY of 115 St. Vincent Street, Glasgow, in the County
of Lanark, North Britain, Civil Engineer and Patent Agent do hereby declaro the
nature of the said Invention for AN IMPROVED CART WITH A REVOLVING AXLE
to be as follows:-
This Invention, which relates to an improved cart, is more especially adapted for
conveying goods over rough country, is provided with a revolving axle, and has
for its object to combine the advantages of having the wheels rigidly fixed on the
axles so as to cause the wheels and axle to revolve together, as in the case of
railway wheels and axles, whilst coupled therewith is the further advantage of
independent inotion of the wheels necessary in turning the vehicle, whilst the wear
and tear caused by bushes becoming slack, and all the wear due to the revolution
is confined to the bearing blocks by which the cart rests on the axle whilst these
blocks may be very much worn without any inconvenience arising, and when
necessary are easily removed. From these improvements the friction experienced in
ordinary constructions of carts and axles is diminished to a minimum, for as the
wheel and axle move together there is practically no difference of the motion of
their bearing surfaces on each other, and as there is thus none or except occasionally
very little relative motion it results that there is no friction.
The Invention consists in attaching one wheel rigidly to a revolving axle, whilst
the other whcol revolves upon the said revolving axle.

I, SAINT JOHN VINCENT DAY, of 115 St Vincent Street, Glasgow, in the County
of Lanark, North Britain, Civil Engineer and Patent Agent do hereby declare the
nature of my Invention for "AN IMPROVED CART WITH A REVOLVING AXLE,"
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :—
This Invention, which relates to an improved cart, is more especially adapted for
conveying goods over rough country. The improved cart is provided with a

page_text: revolving axle and has for its object to combine the advantages of having the
wheels rigidly fixed on the axles so as to cause the wheels and axle to revolve
together as in the case of railway wheels and axles, whilst coupled therewith is the
further advantage of the motion of the wheels independently of each other when
turning the vehicle, or at times when the two wheels require to revolve at different
speeds, whilst the wear and tear caused in the ordinary mode of mounting cart
wheels by the bushes becoming slack, is got rid of, and the wear and tear due to
the revolution of the wheels is confined to the bearing blocks by which the cart
rests on the axle, and these blocks may be very much worn without inconvenience
arising, and when necessary are casily removed.
The Invention consists in attaching one wheel rigidly to a revolving axle whilst
the other wheel revolves upon the said rovolving axle.
And in order that the said Invention may be most fully understood and readily
carried into eflect, I will proceed to describe the Drawings hereunto annexed.
DESCRIPTION OF DRAWINGS.
Figure 1, is an end elevation of a cart with a revolving asle constructed
according to and constituting this Invention.
Figure 2, is a section through the same representing the revolving axle in
longitudinal section.
In carrying these improvements into practice a horizontal axle a, is provided, and
upon it the cart b, rests through the blocks or bearings c.-These blocks or
bearings c, may be secured to the underside of the cart b, by screws or by other
equivalent means, and they may be provided with the straps or covers d, for
retaining the axle a, in its proper position within the said blocks or bearings.-The
axle a, is or may be provided with the collars e, for preventing it from moving
Interally. One wheel f, is rigidly attached to the axle a, by means of the pins g,
passing therethrough, or the said wheel may be secured by keys or by other
equivalent means.-The other wheel h, is free to rotate upon the axle a, and for
this purpose the hub i, of the said wheel is or may be provided with the inetal
bush This wheel h, is retained in position upon the axle a, by the cotter ki,
which passes through and is secured on the said axle.
Having now particularly described and ascertained the nature of this Invention,
and in what manner the same is to be performed, I declare that what I claim is :-
The improved cart b, with the revolving axle a, whereon one wheel f, is rigidly
secured so as to revolve with the said axle, whilst the other wheel h, is mounted
loosely thereon so as to revolve independently of the said axle a, and wheel, as
hereinbefore set forth with reference to the accompanying Drawings.
