Abstract
A recirculating parts washer is disclosed that features a vertically mounted base and a sink and lid rotatably connected to the base. The recirculating parts washer features a cleaning fluid supply container which is separate from the sink but connected to it via a supply line and a drain line.
Cleaning fluid is circulated to the sink via the supply line by means of a submersible pump submerged within the cleaning fluid inside the cleaning fluid supply container. Cleaning fluid returns to the supply container via the drain line, thus enabling the cleaning fluid to be reused over and over again until it is exhausted.
By having the sink and lid rotatably mounted to the base of the recirculating parts washer, the bulk of the assembly can be conveniently pivoted upwards and back against the wall when not in use. The recirculating parts washer also features a direct current power supply assembly.

BACRG20UND O~ ~E INVE~TION
Field of the Invention This invention relates to the equipment used to wash small machine parts by hand using cleaning solutions. More particularly, this invention relates to a novel recirculating parts washer for accomplishing this purpose.
Doscrlption of Rolatod Art Wherever machines are made, used or repaired, the need to clean small parts is present. Although, in some circumstances, the need is readily met, in others it is met only with difficulty and at a substantial cost.
For example, many machine shops around the world labor under the burden of extremely small work environments. In these constricted work areas, space is at a premium. Large parts washing areas, while convenient, are inefficient in that they impede the ability of workers to utilize the space around them for other equally important tasks.
Furthermore, under such conditions, safety issues become increasingly important. When numerous kinds of machinery are operated in close proximity, the dangers associated with having open containers of potentially volatile chemicals increase.
Smaller sinks and increased policing of chemical handling practices do not really solve the problem. They simply make the washing of part~ less efficient in the inte~est ~f safety.
What is needed is a parts washing facility that is spacious when in use and compact when idle. Preferably, such a station wo~ld facilitate the handling of the cleaning fluid, both from the standpoint of cleaning the S parts and from the standpoint of replacing the cleaning fluid when it has exhausted its useful life. Furthermore, it would be extremely desirable for the facility to promote (rather than undermine) safe and environmentally sound workplace practices.
Finally, the parts washing station's utility would be greatly increased if it featured some measure of portability, so that work vehicles would have the same access to an efficient parts washing facility that the main office does.

DETAILED DESC~IPTION
Referring to FIGURE 1, a recirculating parts washer 10 is shown. The recirculating parts washer 10 comprises a base 12; a sink 14 rotatably connected to the base; and a lid 16 rotatably connected to the base as well. In the particular embodiment shown in FIGURE 1, both the sink 14 and the lid 16 are hinged about pins 18 to the base 12. As is apparent from the general purview of FIGURE 1, the base 12 may be mounted to any convenient flat, stable, and vertical surface.
The recirculating parts washer 10 also comprises a separate cleaning fluid reservoir 20 containing a cleaning fluid 22. The separate cleaning fluid reservoir 20 communicates with the sink 14 by means of a drain line 24.
This drain line 24 has a drain line inlet end 26 communicating with the sink 14 and a drain line exit end 28 commnnicating with the separate cleaning fluid reservoir 20.
The recirculating parts washer 10 further comprises a submersible pump 30 submerged in the cleaning fluid 22.
The submersible pump 30 hag a suction opening 32 co~mllnicating with the cleaning fluid 22 and a discharge opening 34 commlln;cating with the sink 14 by means of a supply line 36. The supply line 36 is a length of tubing defined by its supply line inlet end 38 (which commllnicates with the discharge opening 34 of the submersible pump 30) and its supply line exit end 40 (which communicates with either the sink 14 or a washing brush 70 as shown in FIGURE
1). The submersible pump 30 also comprises a power cable 42 transferring power from a power supply assembly 44, which is attached to the base 12, to the submersible pump 30.
In practice, centrifugal submersible pumps have been found to be useful, although other types of pumps would likely be effective as well. Supply and drain lines featuring a 3/8" diameter have been found to provide a sufficient flow rate for cleaning and recirculation.
It will be appreciated at this point that important advantages stem from the use of the separate cleaning fluid reservoir 20 and the submersible pump 30. One advantage stems from the fact that the separate cleaning fluid reservoir 20 is preferably the container in which the cleaning fluid 22 is shipped to the user. One-gallon containers of cleaning fluid have been found to have a neck large enough to accommodate a properly sized submersible pump 30. Whenever cle~ning fluid 22 i9 too dirty to be of further effective use, the submersible pump 30 is simply removed from the current separate cle~ni ng fluid reservoir 20 and placed inside a new one. This allows for an almost llhands off~l replacement of cleaning fluid 22, frequently a desirable safety feature.
The recirculating parts washer 10 preferably comprises at least one adjustable support arm 46 attached to the base 12. A comparison of FIGURES 1, 2, and 3 reveals that the adjustable support arm 46 i9 preferably adapted to hold the sink 14 in at least two temporarily fixed positions. This is effected in the embodiment shown in FIGURES 1-4 by means of an adjustable support arm 46 that comprises telescoping concentric tubes, although concentric members of any convenient cross-sectional shape (e.g., square, rectangular) would also likely be effective.
Referring now to FIGURE 2, adjustable support arm 46 comprises two telescoping concentric tubes, inner concentric tube 48 and outer concentric tube 50. Each concentric tube has an engaged (i.e., telescopically engaging) end and a free end. As depicted in FIGURE 2, the free ends are outer free end 50a (connected to the sink 14) and inner free end 48a (connected to the base 12). The engaged ends are outer engaged end 50b and inner engaged end 48b.
As depicted in FIGURE 2, when the recirculating parts washer 10 is not in use, the sink 14 may be elevated to the mAYimllm extent allowed by the apparatus, dramatically reducing the space the invention occupies in the places where it i3 used. Furthermore, in this configuration, exposure of workers and the workplace to potentially volatile cleaning fluids 22 and their fumes i9 minimized.
Note how, in this position, the lid 16 is tightly and safely sealed against the sink 14. The use of the adjustable support arms 46 makes this possible. In particular, the telescoping concentric tubes 48 and 50 of the adjustable support arms 46 extend so that the distance between the free ends 48a and 50a is extended as far as the apparatus will allow. Note that locking means 78 (in FIGURE 2, a spring-activated catch or button) releasably holds the sink 14 in one of at least two positions. In FIGURES 1, 3, 4, and 5 the locking means holds the sink 14 in a substantially horizontal position ready for use. In FIGURE 2, the locking means 78 holds the sink 14 in an elevated position for short- or long-term storage.
Referring now to FIGURES 3 and 4, the recirculating parts washer 10 preferably comprises a fusible link 52 suspending the lid 16 in an open position at an ordinary operating temperature (as depicted in FIGURE 3) but releasing the lid 16 to cover the sink 14 at a higher temperature determined by the melting point of the fuse material (as depicted in FIGURE 4). Most preferably, the fusible link 52 comprises a fuse 54 and a chain 56, so that, if a volatile cleaning fluid 22 in the sink 14 should unexpectedly ignite, the ambient heat would raise the fuse 54 to its melting temperature, aliowing the chain 56 to drop lid 16 forward, so ag to quickly cover the sink 14 and smothe~ the fire.
Those of ordinary skill in the art will recognize that the fusible link 52 may be designed to activate at whatever temperature is appropriate under the circumstances surrounding use of the invention. In the interest of safety, the inventors and their assignee frequently set their fusible links 52 to engage at a temperature of about one hundred fifty eight (158) degrees Fahrenheit (about seventy (70J degrees Centigrade).
Returning now to FIGURE 1, the recirculating parts washer 10 preferably employs a power supply assembly 44 comprising a jack 58 suitable for receiving a DC (i.e., direct currentJ power cable 64 from either an AC-to-DC
(i.e., alternating current to direct currentJ converter 66 ~as shown in FIGURE lJ or a battery (not shownJ, a resetable thermal fuse 60, and an on-off switch 62. Such a power supply assembly 44 allows the recirculating parts washer 10 to be used both in a conventional shop environment (where a conventional alternating current (ACJ
power supply is likely close at handJ or at a remote location where a vehicular battery can provide a useful local source of direct current (DCJ power. In the event of a pump motor burnout, the resetable thermal fuse 60 prevents burnout of the power supply.
It will be appreciated by those of ordinary skill in the art that according to a preferred emho~im~nt of the recirculating partg wagher 10, the surfaces of the sink 14 are angled in such a way that the force of gravlty urges the cleanlng fluid 22 to the drain line inlet end 26 (see, e.g., FIGURE 1). According to a particularly preferred embodiment, lid 16 is equipped with magnets 72, a~ depicted S in FIGURE 1, to secure small, newly cleaned parts to the lid 16 (allowing them to air dry more quickly and allowing the uQer a greater amount of room in the sink 14 to clean the remaining part~).
Affixing an appropriately sized shelf 74 to the base 12 (see FIGURE 5) ensures proper positioning of the separate cleaning fluid reservoir 20 and helps to prevent accidental disruption of the container. Similarly, a separate cleaning fluid reservoir cap 76, fitted with appropriately sized holes 80 to accommodate the power cable 42, drain line 24, and supply line 36, also helps to prevent accidental spillage and unnecessary evaporation of the cleaning fluid 22 (see FIGURES 1 and 5).
While several embodiments of the invention have been shown and described, other variations (which are in reality equivalents) will be readily apparent to those of ordinary skill in the art. Thus, the invention i9 not limited to the embodiments shown and described herein but, rather, i9 intended to cover all such variations as may be within the scope of the following claims.
