ISAAC HEFFRON, OF GALVESTON, TEXAS.
SEWER-TRAP.
SPECIFICATION forming part of Letters Patent No. 506,690, dated October 17, 1893.
Application filed November 25, 1892. SerialNo. 453,119. (No model.)To all whom it may concern:
Be it known that I, ISAAc HEFFRON, a citi-
zen of theUnited States, residingat Galveston,
in the county of Galveston and State of Texas,
5 have invented certain new and useful Im-
provements in Sewer-Traps; and I do declare
the following to be a full, clear, and exact de-
scription of the invention, such as will enable
others skilled in the art to which it appertains
to to make and use the same, reference being
had to the accompanying drawings, and to
the letters of reference marked thereon, which
form a part of this specification.
My invention relates to traps for sewage.
15 The main object of my improvements is to
prevent the grease and other extraneous mat-
ter from sinks, and other fixtures in the house
to effect a lodgment in the sewer, to the con-
sequent obstruction and clogging up of the
20 same. Such a condition of things is a con-
stant menace to health, and results in costly
and frequent repairs.
The invention consists in the following con-
struction and combination of parts which will
25 first be fully set forth and described and the
features of novelty then pointed out in the
claim.
In the drawings-Figure 1 represents a sec-
tional elevation of a device to which I have
30 applied my improvements. Fig. 2 is a detail
view of the strainer.
A represents a compartment of a buiding.
B is a sink or other fixture therein.
C is a vertical vessel, located within or with-
35 out the building, to receive the flow of the
basin or sink B.
D is a pipe connecting sink B and cylinder
C through which the water, grease and sedi-
ment enter the latter.
40 E is a strainer having a flange which snugly
fits the interior bf the cylinder C. Its normal
position is above the discharge pipe I.
G is a cover of the vessel C, and F, a rod
attached thereto, and also to the strainer E,
45 by means of which, when the cover is lifted,
the strainer is withdrawn from the cylinder
and the accumulated grease thereon removed.
It will be seen that a collecting chamber is
formed below the normal position of the
50o strainer-piston, and that the discharge-orifice
thereof is just below the strainer piston. Any
sedimentary matter which may therefore findits way through the piston E, falls into the
bottom of the cylinder C, the discharge I be-
ing so high up that it does not disturb the 55
sluggish character of the contents by any agi-
tating currents. This collecting chamber is
cleaned as occasion may require when the
strainer is out of the cylinder. The supple-
mentary cylinder H acts to further check any 6o
sediment which may succeed in getting
through the pipe I.
Any grease which may pass through the
strainer E and enter the vessel H, is caught
and held therein. 65
Vessel H is preferably arranged alongside
the vessel C. Pipe I connects the vessels C
and H near the bottom thereof.
The cover J of the cylinder H has an open-
ing 0 for the purpose of ventilating the trap 70
and intercepting the gas or other odors which
may find their way in from the sewer.
L is the pipe which connects with the sewer
or drain, and M, a pipe leading from cylinder
H thereto. 75
Kisa strainer receptacle covering the mouth
of pipe M, and is adapted to hold a cake of
lye or similar substance, should the discharge
at that point contain any greasy particles.
The accumulated grease in the vessel C is 80o
intended to be removed at intervals by sim-
ply withdrawing the strainer E and replacing
the same.
I do not wish it understood that I limit my-
self to the precise arrangement and construe- 8c
tion herein shown, as I may vary the size,
shape and material in setting up these sewer
traps, as well as their relative arrangement.
I claim-
The combination of two upright cylinders, 9c
the first being provided with a reciprocating
strainer-piston normally resting some dis-
tance from the bottom, a collecting-chamber
beneath the piston, and an inlet; and the sec-
ond cylinder having a cap, a vent, an outlet, 95
and a strainer therefor, both cylinders being
provided with a connecting pipe some dis-
tance above the bottoms of said cylinders.
In testimony whereof I affix my signature in
presence of two witnesses.
ISAAC HEFFRON.
