Improvements in or connected with Machines for Trussing and
Pressing Hay, Straw, Clover and the like.
I, JOSEPH BRADBURY, of Brook Ironworks, Charles Street, Manchester, in the
County of Lancaster, Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in portable machines for trussing and press-
ing hay, straw, clover and the like materials and more particularly to such machines
as have combined weighing apparatus, the object of the invention being to provide
a suitable and cheap anti-vibration spring arrangement to relieve the machine
somewhat of the jarring when travelling upon its wheels along the roads. Such
machines are usually provided with two travelling wheels and with removeable
shafts for a horse, and have hitherto generally been unprovided with springs,
the ordinary springs being unsuitable and others being more complicated and
costly. In carrying out my invention I mount the travelling wheels upon two
comparatively short axles each of which is mounted so as to be capable of oscilla-
tion in a vertical plane upon the frame of the machine, preferably at the back so
that the machine may be kept as near to the ground as possible. I employ
suitable guides each having a recess formed therein, so that when applied and
bolted to the framework of the machine they prevent side play of the axles but
permit vertical movement of the same within limits. The recess is formed pre-
ferably in the upper part of each guide and there is placed therein a suitable
spring preferably a helical coil.

Improvements in or connected with Machines for Trussing and
Pressing Hay, Straw, Clover and the like.
I, JOSEPH BRADBURY, of Brook Ironworks, Charles Street, Manchester, in the
County of Lancaster, Engineer, 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 portable machines for trussing and press-

page_text: ing hay, straw, clover and the like materials and more particularly relates to such
machines as have combined weighing apparatus, the object of this invention
being to provide a suitable and cheap antivibration arrangement for the purpose
of relieving the machine somewhat of the jarring it is subjected to when travelling
upon its wheels along the roads, such jarring being detrimental to the weighing
apparatus above referred to.
Such machines are usually provided with two travelling wheels and with
removeable shafts by which a horse can be attached thereto when it is required to
transport the machine, and have hitherto been generally unprovided with springs,
the springs ordinarily used for road vehicles being unsuited to the construction
of the machine and other antivibratory arrangements hitherto proposed being
complicated and costly.
In order that my invention may be more readily understood I have attached
hereunto a sheet, of drawing to which I will now refer.
The said drawings Figure 1 represents an elevation of the back of a machine
such as is now in general use shewing the application of my improvements;
Figure 2 is a plan of the same, Figures 3 and 4 represent two views of my
improved antivibratory arrangement on an enlarged scale and Figures 5 and 6
two similar views shewing a slightly modified construction made in accordance
with my invention.
The improvements consist in mounting the travelling wheels a upon indepen-
dent short axles 6 provided with a pivotted bearing 6 arranged so as to enable
cach axle to move in a vertical plane. The construction shewn in Figure 3 and 4
is the one I prefer at present to use and is shewn as applied to the machine illus-
trated in Figures 1 and 2. In this case the axle 6 is pivotted at one end to the
frame of the machine, preferably a hole 62 being made in the axle and a
bearing bolt or stud 63 being fixed to the frame aforesaid. In order to prevent
side play or drag when the machine is being wheeled and also to support the
spring provided a guide e of any suitable construction for each axle through
which guide the axle passes, and I bolt the guides to the framework. Each guide
is of such dimensions that a certain amount of vertical play only is permitted
and I form each guide with a recess or socket c¹ to contain a helical spring d
arranged above the axle.
In the modification illustrated in Figures 5 and 6 the axle b is formed as a
lever of the first order having its bearing 1 between the ends and having one
end 62 formed to take hold of one end of a pull spring d¹ which has its other end
fixed to the framework. In this case a guide may be dispensed with provided that
the bearing bolt or stud 63 and the axle itself are strengthened.
In some cases I may dispense with coil springs and cause the short axles in
their upward movement to bear against a transverse flat laminated spring mounted
centrally upon the machine at the back thereof.
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 improvements in or connected with machines for trussing and pressing
hay, straw, clover and the like, which consist in the construction and arrangement
of short wheel axles each pivotted to the framework of the machine and capable
of movement in a vertical plane only against the pressure of a suitable spring or
springs substantially as hereinbefore described and illustrated and for the purpose
set forth.
Second: In machines for trussing and pressing hay, straw, clover and the like
the improved construction of travelling wheel axle and combined antivibratory
spring arrangement substantially as hereinbefore described and illustrated with
reference to Figures 1, 2, 3 and 4 of the drawings and for the purpose set forth.
Third: In machines for trussing and pressing hay, straw, clover and the like

page_text: the improved construction of travelling wheel axle and combined antivibratory
spring arrangement substantially as hereinbefore described and illustrated with
reference to Figures 5 and 6 of the drawings and for the purpose set forth.
