LUBE PUMP TELESCOPING ENCLOSURE
Abstract
Enclosure (16) for housing a coupler (18) between a driving rod
(20) and a driven rod (22) comprises a first and a second
preferably cylindrical pieces (30, 28). Said pieces are sized so
that the first piece (30) is able to slide telescopically within
the second piece (28) and are threaded to engage each other when in
operation the enclosure (16) is in a close position, thereby the
enclosure (16) being able to retain lubricant in the inside. For
service, after having drained the lubricant from the enclosure
(16), the two pieces are loosened by screwing the first piece (30)
until the end of the thread is reached, and then the first piece
(30) is slideably telescoped into the second piece (28), thereby
setting the enclosure (16) in an open position an enabling easy
access to the rod coupler (18).

Claims
1. An enclosure for retaining pump lubricant on a pump assembly
having a driver with a piston rod and a pump with a chemical rod,
said rods being joined by a removable coupling, the improvement
comprising first and second generally cylindrical housing pieces,
said pieces sized so that said first piece will telescopically
slide in said second piece and being threaded so as to releasably
engage each other so as being selectively engageable in first and
second positions whereby in said first position, said first piece
is slideably telescoped in said second piece and in said second
position, said first and second pieces arc sealingly engaged with
said driver and said pump.
2. The enclosure of claim I wherein said pieces comprise exterior
surfaces, said exterior surfaces comprising knurling to enable
manual manipulation between said first and second positions.
Description
[0001] TECHNICAL FIELD
[0002] This application claims the benefit of U.S. Application Ser.
No. 61/262,669, filed Nov. 19, 2009, the contents of which are
hereby incorporated by reference.
BACKGROUND ART
[0003] The instant invention is designed for used with plural
component dispensing systems. Previous designs used a single ISO
lube housing piece with a small access hole to get at the coupler
piece. This hole was plugged during operation and needed to be
removed with a tool before servicing. A tool was needed to remove
the coupler pin through the access hole.
DISCLOSURE OF THE INVENTION
[0004] An enclosure will be used to pump throat seal liquid (TSL)
on a hydraulic pumpline. The housing will telescope to allow for
easier and faster access to the pump coupler without the use of
tools. The ISO Lube pump is required on any pump containing
moisture sensitive chemicals, such as isocyanates, in order to
isolate the chemical from moisture.
[0005] While in operation the ISO lube housing will be completely
filled with ISO lube. The coupler piece, which connects the
hydraulic piston rod to the chemical rod, needs to be removed in
order to service the chemical or hydraulic pump. Fluid must first
be drained from the enclosure, and then the locking nut can be
removed by backing it away from the large housing piece. Then the
two housing pieces can be loosened by hand. When the end of the
thread is reached, the small housing collapses into the large
housing, allowing easy access to the rod coupler. See FIG. 2 for a
view of the collapsed enclosure.
[0006] The 3 piece design utilizes knurled surfaces to eliminate
the need for tools. It is also telescoping so the coupler piece can
easily be serviced without the need for a small access hole or any
tools.
[0007] These and other objects and advantages of the invention will
appear more fully from the following description made in
conjunction with the accompanying drawings wherein like reference
characters refer to the same or similar parts throughout the
several views.
BRIEF DESCRIPTION OF DRAWINGS
[0008] FIG. 1 shows a cross-section of the pump coupler with the
enclosure of the instant invention positioned for operation.
[0009] FIG. 2 shows a cross-section of the pump coupler with the
enclosure of the instant invention positioned for maintenance.
BEST MODE FOR CARRYING OUT THE INVENTION
[0010] An enclosure 10 will be used to pump throat seal liquid
(TSL) 12 on a hydraulic pumpline 14. While in operation the ISO
(isocyanates) lube housing 16 will be completely filled with ISO
lube 12. The coupler piece 18, which connects the hydraulic piston
rod 20 to the chemical rod 22, needs to be removed in order to
service the chemical or hydraulic pump 24. Fluid 12 must first be
drained from the enclosure 16, and then the two housing pieces 28
and 30 can be loosened by hand by screwing the small housing piece
30 into the large housing piece 28. When the end of the thread is
reached, the small housing 30 collapses into the large housing 28,
allowing easy access to the rod coupler 18. See FIG. 2 for a view
of the collapsed enclosure. For reinstallation, the housing pieces
28 and 30 are extended until the threads 32 engage and the
enclosure 10 lengthened until it is sandwiched between hydraulic
driver 36 and pump 24. O-ring seals 38 are used to seal enclosure
10 at either end and retain the TSL 12.
[0011] The 3 piece design utilizes knurled surfaces 34 to eliminate
the need for tools. It is also telescoping so the coupler piece 18
can easily be serviced without the need for a small access hole or
any tools.
[0012] It is contemplated that various changes and modifications
may be made to the enclosure without departing from the spirit and
scope of the invention as defined by the following claims.
