I EDWARD PINK jun'. of Staple St. Southwark in the County of Surrey
Jam Manufacturer do hereby declare the nature of my Invention for IMPROVE-
MENTS IN MACHINERY USED IN THE MANUFACTURE of JAMS, MARMALADE and
THE LIKE and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My Invention relates to the mechanism employed for actuating the stirrer used
for stiring or agitating jam marmalade & during the process of boiling, and
consists of an improved construction of stirring apparatus and clutches whereby
a revolving motion is imparted to the stirrer, or its motion stopped when revolving,
the operations of starting or stopping its revolving motion being simultaneous with
those of lowering it into the boiling pan or lifting it out.
According to my Invention I attach to the lower end of a hollow revolving
spindle a metal nozzle or bush having a clutch formed of steel projections keys or
recesses lined with steel made in its upper part, through the centre of this bush
and the hollow spindle to which it is attached, a rod passes, to the lower extremity
of which the stirrer blade or blades are attached, while to the upper extremity of
the said rod a piece of steel is attached having a clutch formed in its sides or
attached to it consisting of projections keys or recesses to correspond with those
formed in or attached to the upper part of the nozzle that is fixed at the lower
extremity of the revolving spindle, these two corresponding clutches being so
arranged that they engage when the stirrer reaches its proper position for most
effectually stirring the contents of the boiling pan over which it is fixed-while
directly the stirrer has been lifted a very small distance above the said position the
revolving motion ceases through the clutches disengaging. Both these clutches are
wholly within the hollow revolving spindle above mentioned.
•
The advantages of my Invention are,-That the form and construction of the
lutches renders them very durable and easy of repair and renewal. That
nclosing them wholly within the hollow revolving spindle prevents the clutches
ecoming clogged with dirt which would obstruct their engaging or disengaging—
And that wholly enclosing them and also stopping the motion of the stirrer
irectly it is lifted through an exceedingly small distance prevents the persons or
pparel of the attendants being injured by the rotation of their projecting parts.
In the annexed Drawings which more clearly set forth my Invention Fig. 1 is
section through the hollow revolving spindle shewing the stirrer rod within it

the clutches only. In these Drawings A is the hollow revolving spindle B the
nozzle in which the lower clutch is formed C the stirrer D the stirrer rod E the
clutch at its upper extremity F F are the projections forming the clutch in the
nozzle BGG the recesses forming the clutch in the upper part of the stirrer
rod D.
It will be seen that when the stirrer rod D is lowered until the recesses GG
engage with the projections FF in the nozzle B the revolving motion of the spindle
A will be imparted to the stirrer C through the rod D-also that as soon as these
are disengaged the revolving motion will cease.
It must be understood that I do not confine myself to the exact materials
mentioned in this Specification as steel might be replaced by casehardened iron or
other hard material, nor do I confine myself to the exact form position or number
of the projections keys or recesses forming the clutches.
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 :
The general arrangement and construction of the clutches wholly within the
revolving spindle and their combination with the revolving spindle and stirring
rod substantially in the manner and for the purposes berein stated.
