I, WILLIAM FAIRHURST of Pemberton in the County of Lancaster Engineer do
hereby declare the nature of my said invention for "IMPROVEMENTS IN ECCENTRICS
APPLICABLE FOR APPARATUS FOR BOTTLING AERATED WATERS" to be as follows:-
The invention relates to improvements in eccentrics whereby the throw can be
altered and fixed at any given distance, and is chiefly designed for use in actuating
the syrup pumps in machines for bottling mineral and aerated waters, though it
may be applied to other machines when a movable or adjustable eccentric is
required.
It consists of a ring which carries the strap of the eccentric pivotted to a plate by
means of a fixed and a movable pin, and a pawl or catch which engages with a
projecting key or lug carried on the shaft by means of which the eccentric may be
thrown out of gear.
In carrying out the invention I prefer to key or otherwise fasten to the actuating
sbaft a boss or hub carrying a projecting key or lug. On this boss is fitted the
plate which forms one side of the eccentric. This plate is free to revolve on the
fixed boss. To this plate is pivotted a ring by means of two pins or bolts, one
fixed and the other moving in a slot. The pivots which hold the ring are so placed
that the ring in one position will be concentric with the shaft upon which the
eccentric is placed, and moving on the fixed pin, the other moving in the slot, the
throw of the eccentric can be adjusted.
For use with bottling machines a scale placed on the edge of the slot and a mark
or pointer, on the movable pin could be used to indicate the quantity of syrup
pumped at each stroke with the eccentric placed in that position. Carried by the
plate of the eccentric is a small catch which engages with the key or lug on the
fixed boss or fixed to the shaft. This catch is such that when in action, it will
engage with the key when the shaft turns in either direction, but at the same time
allows the shaft to be turned in the opposite direction for about half of a revolution
before coming into play, to reverse the eccentric. This catch may be withdrawn
or thrown out of gear and the central shaft allowed to rotate without actuating
the eccentric.
The eccentric may be formed with a plate at each side of the movable ring to
keep the strap in position or with, but one plate; a flange being made on one
side of the ring, the other abutting against the plate.

I, WILLIAM FAIRHURST of Pemberton 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:
The invention relates to improvements in eccentrics, whereby the throw can be
altered and fixed at any given distance, and is chiefly designed for use in actuating
the syrup pumps in machines for bottling mineral and aerated waters, though it
may be applied to other machines where a movable or adjustable eccentric is
required.
It consists of a ring which carries the strap of the eccentric pivoted to a plate,
by means of a fixed and a movable pin, and a pawl or catch, which engages with
or locks into the shaft or bush thereon by means of which the eccentric may be
thrown out of gear.
It is best described by aid of the accompanying drawings in which,
Figure 1 is a side elevation of the invention.
Figure 2 transverse sections of same.
Figure 3 side elevation of a slight modification of same.
A is a boss or sleeve, keyed or otherwise attached to the actuating shaft, so as to
turn with it. B is a plate bored out to fit onto the end of the boss being made so
as to revolve freely thereon. It forms one side of the eccentric. C is a ring
provided with pin holes c, through each of which it is pivoted to the plate B, by
the screwed pins b, b¹. These pins fit closely in the holes c, so as to allow but
little play. The pin b₁ also fits into a closely fitting hole in the plate B, so that
when screwed up, there will be no room for play. The pin b fits into a slot 6" in
the plate B. When the ring C is in position, and the pin b on one edge of the
slot 61, it is concentric with the actuating shaft. By moving the pin b in the slot,
the ring becomes eccentric, and the throw is regulated by the position of the pin b¹
in the slot 6, D is a small catch or pawl carried by a spindle E in the plate B, the
end of the pawl fits into a recess a cut in the boss A¹, keyed to the spindle and
when engaging with the recess a, the movement of the shaft A carries round the
eccentric. The pawl D is fitted with a small wire spring F, passing at each side
of the spindle E. The spindle is provided with a projecting piece f, which acts
against the wire spring, and has a knob or handle on one end, when the spindle is
in position shown; the projection facts against the spring F to hold the pawl in
position when the spindle is reversed with the projection f on top, the spring acts
to keep the pawl out of contact with the fixed boss, and when in this position
the shaft may revolve without actuating the eccentric. Where it is desired that
the eccentric should turn only in one direction irrespective of the motion of the
actuating shaft A, a device similar to that shown in Figure 3 may be adopted,
were the shaft to be turned in the wrong direction the incline a¹ would lift the
pawl, and allow it to pass,

page_text: For use with bottling machines, a scale G placed on the edge of the slot, and a
mark or pointer H on the movable pin could be used to indicate the quantity of
syrup pumped at each stroke with the eccentric placed in that position.
The eccentric may be formed with a plate at each side of the movable ring to
keep the strap in position as shown, or with but one plate; a flange being made
on one side of the ring, the other abutting against the plate.
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
1st. An eccentric having a movable ring pivoted to or carried by one or more
plates which receive motion from an actuating shaft by means of a pawl pivoted
thereto, substantially as described.
2nd. An adjustable eccentric with movable ring constructed and arranged
Bubstantially as described and shown.
