Multi-use adjustable fit wash-out waste containment apparatus for cement transport equipment and tools
One embodiment of a multi-use, adjustable fit cement washout waste containment apparatus having the capability to be easily and quickly affixed to different types of common cement transport equipment and tools specific to the cement trade. The amply wide adjustable circular opening (10), fitted with a locking drawstring assembly, or toggle, can be sized to readily be affixed to the discharging ends of common cement transport equipment, namely; cement transport truck chutes, cement pump assembly chutes, power buggies, wheelbarrows, etc. Once properly affixed, the containment apparatus acts to contain solid components of the water/uncured cement slurry which results from the washout processes of such equipment and allows partially filtered water to pass through the body (14) of the apparatus. Subsequently, the apparatus, containing the filtered cement waste, can be easily removed from the cleaned equipment and transported to a municipal disposal or reclamation site. Other embodiments are described herein.
This application claims the benefit of provisional patent application Ser. No. 61/069,139, filed 2008 Mar. 13 by the present inventors.

BACKGROUND1. Field
This application relates to waste containment devices, specifically to such devices which contain waste produced from the washing out of cement transport equipment and tools.
2. Prior Art
Cement tradesmen and do-it-yourselfers use a variety of cement transport equipment and specialized tools in the process of completing cement construction projects. To properly care for and maintain these items, equipment, and tools that contact uncured cement are washed-out or rinsed off with water immediately after use. The resulting rinse-water/cement slurry is problematic to handle and the development of efficient techniques to manage this waste slurry has confounded tradesman in the past. Cement wash-out slurries, if not contained, often damage property, namely, landscaping and sewage systems, and they expose contractors to customer complaints, unneeded liability, and labor costs.
In the past, these waste slurries were haphazardly discharged on-site or directly into the nearest sewage system. Recent environmental concerns and municipal ordinances have pressured tradesmen to manage these on-site waste slurries properly. Although, several complex cement waste containment and reclamation processes and mechanical devices have been developed (see U.S. Pat. No. 6,435,581 (2002), U.S. Pat. No. 6,461,098 (2002), U.S. Pat. No. 7,118,633 (2006), U.S. Pat. No. 7,124,767 (2006), U.S. Pat. No. 7,232,189 (2007), U.S. Pat. No. 7,364,627 (2008)), none is compact, portable, and easy to use, and none possesses multi-use functionality to manage waste slurries on-site. U.S. Pat. No. 6,783,007 to Arbore (2004) discloses an arm assembly mounted directly to a cement delivery truck specifically designed to retain waste emanating from the truck's chute. This fixed mounted arm assembly is relatively expensive to manufacture, time consuming, complex to install, and limited to containing the on-site waste emanating from the truck's chute. U.S. patent application Ser. No. 10/722,153 to Inglese (2003) shows a rectangular bag with straps which is attached to a cement delivery vehicle. This device is relatively large and expensive to produce and it requires four (4) docking locations to secure its mounting straps to a cement delivery vehicle or the addition of a chute assembly to accept waste from a cement pump system.
The capacity of this device is voluminous enough to accept a quantity of waste cement that might otherwise prevent its transport without the aid of several laborers or machinery. Inglese's device cannot easily be adapted to accept the wash-out wastes produced by other common on-site cement tools and equipment, such as power buggies, wheel barrows, mixing barrels, specialized cement tools, etc. Further, Inglese's device does not possess the relatively universal mounting capability to be quickly and easily affixed to the variety of equipment named above, and therefore accept the waste slurries which result from rinsing and washing them. And finally, Inglese's device suffers from a size disadvantage that requires a relatively large space to store it both before and after use.
Advantages of the present embodiment relative to prior art include:
(a) light weight construction.
(b) adjustable opening, allowing it to “universally fit” or attach to many types of cement transport equipment and tools.
(c) ease of storage, both when empty, and fill, due to relative small size.
(d) designed to be quickly and easily mounted and removed without the use of tools.
(e) portable and easily handled by one person.
(f) relatively simple and inexpensive to produce.
These and other advantages of one or more aspects will become apparent with consideration of the ensuing description and accompanying drawings.
SUMMARYIn accordance with an embodiment, a waste containment apparatus comprises a conical body having an adjustable opening on one end and the conical body being constructed of a durable porous material.

One embodiment of the waste containment apparatus is illustrated in
Regarding equipment which utilize a chute structure to transport cement, as shown in
Additionally, equipment which utilizes a bucket structure 30, such as, a power buggy or wheelbarrow, to transport cement, is washed out in a similar fashion, as shown in
In further contemplation, the apparatus, as shown in
From the description above, a number of additional advantages of the main and alternative embodiments of my waste containment apparatus become evident:
(a) Less labor and time required to attach, utilize and detach my waste containment apparatus relative to similarly functioning devices.
(b) Relatively less area required to perform clean-out activities; can be used in “tight” spaces.
(c) Several waste containment apparatus' can be easily stored in a relatively small space.
(d) Few moving parts and minimal maintenance required for repeated use.
(e) After being “filled” with cement waste my containment apparatus can be transported off-site and safely disposed of at a municipal landfill.
Accordingly, the reader will see that at least one embodiment of the waste containment apparatus can efficiently contain, filter, and separate cement waste slurries that result from washing cement transport equipment and tools following transport and placement activities. After use, the apparatus and the waste material contained inside can easily be disposed of similarly to municipal, “household” waste or it can be disposed of at an approved recycling site or reclamation area. Once empty, the containment apparatus can be rinsed off, dried and reused. Furthermore, due to its compact size and lightweight construction, one tradesman/laborer can easily manipulate the containment apparatus when empty or filled with waste. Relative ease of manufacturing and the existence of inexpensive, and readily available component materials, allow for relatively inexpensive production and retail costs of the apparatus. Consequently, tradesmen and do-it-yourselfers will now have an inexpensive, lightweight, portable and easy to use alternative for managing cement effluent slurries resulting from washing cement equipment.
Although the description above contains many specifications, these should not be construed as limiting the scope of the embodiment but as merely providing illustrations of some of the presently preferred embodiments. For example, the reticular body of the apparatus can have different shapes, such as oval, square, rectangular, cubical, trapezoidal, etc.. The circular opening of the apparatus can be comprised of various cincture components, such as, belt and buckle configuration, commercial hook and loop mating materials, bands comprised of rubber, metal, synthetic or natural cord, etc.. The drawstring toggle can be a commercially available unit or one fashioned from wood, metal or metal chain, plastic etc. Further, the apparatus can be secured or held in position with the addition of straps, ropes, or cord like material wrapped around the perimeter and tied in a knot, the use of adhesives, loops, hooks, clamps, rubber bands, “bungy” cord, etc. Thus, the scope of the embodiment should be determined by the appended claims and their legal equivalents, rather than by the examples given.
