SIDNEY TURTLE PRESTOR,
HENRY JOHN BALLETT,
Improvements in Grease Traps.
We, SIDNEY TURtle Prestor, of Peak Cottage, Avenue Road, Upper Parkstone,
Dorsetshire, Plumber and Gas Fitter, and HENRY JOHN BALLETT, of Albert Road,
Upper Parkstone, Dorsetshire, Contractor, 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 :-
Our invention has for its object improvements in grease traps by which we
provide a means for enabling the trap to be readily cleansed and at the same
time render the frequent collection and removal of the more solid refuse an easy
matter. Our trap also enables the drain to be swept when required without dis-
turbing the drain or ground.
In order that our invention may be clearly understood and more eaisly carried
into practise we have appended hereunto one sheet of drawings upon which we
have fully illustrated the nature of our said improvements.

page_text: Figure 1 is a vertical sectional view of the trap complete.
Figure 2 is a view of the internal receptacles removed from the trap.
Figure 3 is a reduced plan of Figure I.
In earring our invention into effect we provide the round earthenware outer
body A and the earthenware dished portable top B with central aperture 6¹ the
flange b² of which rests in the top rebate a¹ of the body A and the aperture of
which leads on to the cast iron or other suitable grating C which rests on the
lower rebate a² of the body A. Below this grating the removable and portable
cast iron or other suitable receptacle D is suspended in the centre of the outer
body A upon the internal projecting rim a³ which is either attached to the said
body A or formed in one piece with it as shewn. The receptacle D is provided
with the circular flange d¹ turned over as shewn and provided with the openings d³
through which the water passes, a complete water seal being at the same time
retained as the level of the water is always above the top of the apertures. The
handle E is provided for assisting the easy removal of the receptacle containing
the dirt and to allow of the ready sluicing and flooding of the body of the trap
and drain.
In some cases where an outlet pipe is required to discharge into the trap we
may provide the diminished connection shown by dotted lines F if we so desire
in which case the top B would not be required.
We do not confine ourselves to the exact shape of the aperture ² shewn, or of
the particular formation of the top B and body A.
Having now particularly described and ascertained the nature of our said
intention and in what maner the same is to be performed, we declare that what
we claim is:-
1st. In grease traps the combination of the body A having an internal rim
with a flanged receptacle D having apertures such as substantially as and for
the purpose herein set forth and illustrated.
2nd. In grease traps the combination of the trapped body A portable top B
and grating C substantially as and for the purpose herein set forth and illustrated.
Dated this 23rd day of October 1899.
