I HENRY WILLIAM ROBINSON of 25 S. George's Terrace Northampton in the County
of Northampton, Dairy Farmer, do hereby declare the nature of my invention for
IMPROVEMENTS IN THE CONSTRUCTION OR FORMATION OF AXLE'S, AXLE BOXES, HUBS,
AND THE SPRING SHACKLES, OF CARTS, CARRIAGES, AND OTHER VEHICLES to be as
follows:-
The object of this invention, is to allow wheels to revolve with more ease and
therefore less expenditure of strength on the part of the Horses. The spring shackles
being so formed to lessen the vibration when the vehicles are not sufficiently
weighted to bring the main springs in action.
In carrying out my invention for use on heavy Carts, or Drags, I proceed as
follows-
At the back, or that end of the Axle near the body of the cart, I form a ring, or
collar, grooved to receive a number of large balls, these Balls projecting about one third
of their Diameter above the collar, the groove being so formed to prevent their
slipping out. In manufacturing new axles, this collar would form part of the axle,
but for use on existing axles, this collar would be manufactured separately, and driven,
and wedged on. At the back of the collar, is a plate and washer, for the purpose of
excluding dirt, and keeping the oil in the box. For the outer, or Linch-pin end of the
axle, I form a separate ring or collar, grooved and fitted with balls similar to
the aforesaid one. The boxes are formed in two parts, shaped to cover both the collar

put on, the separate collar is fitted on the axle, secured, either by linch-pin, or nut, and
then another oil plate or cap is fitted to the box. For trade carts, or carriages of a
lighter nature, I 'form one, or more grooves, with smaller Balls in each ring, or
collar, the boxes having in some cases a lining, first, of rubber or material of a similar
nature, and then a metal casing.
In manufacturing cast, or metal, hubs, they would be deeply recessed on either side,
to receive the said lining and casing. The shackles are formed somewhat like a
'D' shackle but shaped to allow of spiral springs, or rubber cush, or both, to intervene
between them, thus lessening the vibration in the carriage.

Improvements in the Construction or Formation of Axles, Axle-
boxes, Hubs, and the Spring Shackles of Oarts, Carriages, and
other Vehicles.
1 HENRY WILLIAM ROBINSON of 25 S. Georges Terrace Northampton in the County
of Northampton Dairy Farmer 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 improvements in the construction or formation of Axles,
Axleboxes, Hubs, and the Spring Shackles of Carts Carriages and other Vehicles the
object of the invention being to allow the Wheels to revolve with more ease and
therefore less expenditure of strength on the part of the Horses. The spring shackles
being so formed as to lessen the vibration when the vehicles, are not sufficiently
weighted to bring the main-springs in action.
In carrying out my invention for use on heavy carts or drays-I proceed as
follows at the back or that end of the axle near the body of the cart I form a ring
or collar grooved to received a number of large balls-the balls projecting about one
third of their Diameter above the collar the groove being so formed as to prevent their
slipping out. In manufacturing new axles this collar would form part of the axle but
for use on existing axles, this collar would be manufactured separately and driven and
wedged on. At the back of the collar is a plate for the purpose of excluding dirt or grit
and keeping the oil in the box, for the outer or Lynchpin end of the axle I form a seperate
The boxes are
ring or collar grooved and fitted with balls similar to the aforesaid one.
formed in two parts shaped to cover the collar and balls, having a ledge inside to take
the side bearing. After the wheel is put on, the seperate collar is fitted on the Axle,
and secured either by Lynchpin or nut, and then another oil plate or cap is fitted to the
box. For trade carts, or carriages of a lighter nature I form one or more grooves
with smaller balls in each ring, or collar. The collars, and grooving, being either
manufactured as part of the axle or fitted thereto.
In manufacturing cast or metal Hubs, for these axles they would be deeply
recessed on either side to allow of the collar and boxes fitting therein. I sometimes use
a lining of rubber, or packing, to cover over the box. Where a cheaper axle is desired,
1 dispense with the outer collar near the Lynch-pin, in which case the box would be
formed in the ordinary way, to cover one collar only. The shackles are shaped to
allow of coil springs or rubber cush or both to intervene between the springs and the
body of the vehicle, thus lessening the vibration in the carriage.
In order to enable my invention to be more fully understood, I will proceed to
describe the same, by reference to the accompanying Drawings in which
Fig. 1. Sheet 1, is the collar or ring referred to; shown with the balls projecting
therefrom.
Fig. 2. is the section of the same from A. to B.

page_text: Fig. 3. sheet 2. is a section of an ordinary heavy cart hub, and axle, fitted with the two
collars, according to my invention. Similar letters in all the Figures represent similar
parts. C, is the collar. D. are the balls. E. is the ordinary cart axle. F. is the
hub. G. is the box. H. is the ledge referred to. I. is the Lynch-pin. J. is the oil
plate. The shackles for connecting the springs to the body of the vechicles are shown
on sheet 3. in attaching to some vehicles, a slight alteration may have to be made in
shape of the Irons, the principle however remaining the same. Fig. 4 is a front
shackle for trade carts, dog carts, &c. Fig. 5 is a hind one for the same where
no cross spring are used. Fig. 6 shows the same as a front shackle on a "Hansom
Cab." K. is the shackle which works on a pivot. L. M. is the rubber cush.
N, is a coil spring. O. are the ordinary springs. P. is the body of the vehicle.
The coil spring works on a half moon shaped Iron shown as Q.
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 :-
First, the manufacture and use of the rings or collars, having one or more
grooves fitted with balls projecting therefrom, the said collars and grooving, being
either part of the axles, or attachable thereto.
→ Secondly, the boxes shaped to cover collars, and balls, having ledges therein to
take the side bearing, the metal hubs recessed to receive the collars, &c.
Thirdly The spring shackles formed to allow of coil springs, or rubber cushes, or
both, to intervene between the springs and the body of the vehicle to lessen the
vibration therein.
Fourthly The improvements in the construction of axles, Axleboxes, hubs, and the
spring shackles of carts, carriages and other vehicles being substantially as, and,
for the purposes herein before described and also represented in the accompanying
drawings.
