Description
Background of the Invention
Commercial restaurants have expanded in the past years to become large volume businesses, offering services to thousands of people each day. To supply the large volume demand for food services, commercial restaurants have resorted to cooking on large fryers and offering fast food services. Consequently, the volume of hot fats and greases accumulated in restaurants has also increased as the volume of food services have expanded. Commercial restaurants cannot dispose of the hot fats and greases through their drainage system since the grease eventually settles and clogs the drain pipes. Therefore, a need has arisen to provide a safe effective means of disposing of the large volumes of hot fats and greases.
Safe handling of the hot fats and greases accumulated by commercial restaurants has historically been a problem since anytime a person handles a substance that is scalding hot there is a high risk of serious burning injuries. Most often, commercial restaurants maintain a large storage vat outside the restaurant into which the hot fats are emptied. It follows that the person in charge of disposing of the hot fats and greases not only must safely empty the large fryers into a container, but must also transport the same some distance to the main storage vat. Throughout all this handling the container becomes quite hot, and contact with the container must be avoided to prevent serious burning injury.
In transportation of the container to the main storage vat, the operator may often be required to transport the container across snow, up stairs, or across uneven or rough terrain to reach the main storage vat. Therefore, the container must also provide a stable means of transportation and support, and a means of preventing contact with the hot container.
Safety is the primary objective sought when handling the hot fats and greases, thus it is imperative that contact with hot fats and greases or the hot container be avoided at all times. Therefore, it is also the primary objective of the invention applied for herein to provide a safe, effective means of emptying hot fats and greases from frying vessels and transporting the same safely to a main storage vat.
Brief Description of the Invention
The primary application of our hot fat transport vehicle is its use by commercial restaurants to transport and dispose of their accumulated hot fats and cooking greases on a daily basis. The hot fat transport vehicle has been designed to reduce the likelihood of serious burning injury due to the associated dangers of working with hot fats and greases.
Our hot fat transport vehicle is essentially comprised of an elongated upright container having an off-set inlet port at its top end to facilitate filling with hot fats and greases, and a transporting means connected thereto designed to provide easy, safe handling of said container. Under normal use, the container is filled in the upright position while being supported above ground level by a pair of support legs and wheels. Both the wheels and the support legs are positioned outside the vertical confines of the container to prevent dangerous possible tippage and spillage of the hot fats and greases with consequent danger of a serious burning accident. The wheels serve two purposes; one is for stable support while the container is in the upright position, and the other is to provide an effective means for transportation of the hot fats and greases.
The transportation means is essentially comprised of a pair of generally arcuately shaped strut members, one each mounted on each of the opposite lateral sides of the container The lower end of each of these strut members carries an axle to which the above mentioned wheels attach. The top end of the strut members are interconnected by an insulated handle. Once the container has been filled with the hot fats and greases, the operator can safely and effectively transport the container to a main storage vat by simply pivoting the container onto the wheels and pulling on the handle which interconnects the top ends of the axle struts.
The container carries a baffle plate on its side adjacent to said wheels and handle. The baffle plate is set back from the container and functions as a heat barrier to prevent the operator from coming in contact with the hot container during transportation. The combination of air flowing between the baffle plate and the container, and insulated washers used in connections therebetween further limit heat transfer to said baffle plate.
The inlet port of the container is equipped with a port covering means which rests in an open or closed position as a function of a pair of springs mounted thereto. The hot fats and greases are introduced into the container while the port cover is in the open position. Then the cover is closed during transportation to prevent any spillage of the containers contents. In normal use, the container will be filled while in its upright position and then transported to a main storage vat. The container is then hooked to the main storage vat by a flange mounted on said containers back side. The cover over the port is then opened and the contents in the container may be dumped into the main storage vat by lifting up on the insulated handle carried by the axle.
It is the primary objective of this invention to provide a safe, effective means of emptying hot grease containing frying vessels and transporting such hot fats and greases to a main storage vat.
It is a further objective of the invention to provide a stable upright hot fat transport vehicle for use by commercial restaurants that is easy to safely fill and transport and is safe to handle.

Detailed Description of Invention
As shown in FIG. 1 our invention is comprised of an upright container 10 having opposite lateral sides 10a and 10b, a front side 10c, and a back side 10d. The top portion of container 10 angles upwardly and outwardly beyond its back side 10d. The top end of container 10 terminates with an inlet port 11. The hot fats and greases are drained into inlet port 11 and are stored in container 10 while being transported to a main storage vat(not shown).
The inlet port 11 is covered by a port covering means 12 to eliminate any dangerous spillage of hot fats and greases during transportation. The port covering means 12 is connected to said container 10 by a pair of hinges 13. A cover handle 14 is mounted on the outermost face of said port covering means 12, transversely disposed between its lateral edges 17, to facilitate its opening and closing. The grip portion 15 of cover handle 14 is preferably made of an insulating material to minimize heat transfer from said container 10.
Spring rod 16 is transversely mounted through said lateral edges 17 of port covering means 12. A spring 18 is connected to each end of spring rod 16 and extends therefrom adjacent each opposite lateral side, 10a and 10b, of container 10 to each axle strut 19. Springs 18 are connected to axle struts 19 by means of eyelets 20 stamped and punched therein. The springs 18 function to provide over-dead-center operation of port covering means 12, thereby allowing the operator to fill the container 10 while the port covering means 12 rests in the open position, and to close it during transportation.
Axle struts 19 support a transportation means for container 10, and are connected thereto, one each adjacent to each opposite lateral side, 10a and 10b. The upper portion 19a of axle struts 19 extends upwardly and outwardly towards the front side 10c of the container 10. The top ends of axle struts 19 are interconnected by an insulated transport handle 21, which is used to pull container 10 during transportation.
The lower portions 19b of axle struts 19 extend downwardly and outwardly beyond the vertical confines defined by the front side 10c of container 10. The lower ends of axle struts 19 are interconnected by axle 22. Axle 22 carries an insulated axle handle 23 in telescoping relation thereto to facilitate dumping of the hot fats and greases into the main storage vat.
Wheels 24 are mounted on each end of axle 22. In use, the operator will pull on said transport handle 21, thereby causing the container 10 to roll on wheels 24. Wheels 24 are relatively large, preferably 8 inches or larger in diameter, to provide for easier transportation through mud, snow, and up stairs. Wheels 24 also act in cooperative supporting relation to support legs 25 when the container stands in its upright position. Support legs 25 are connected to the lower portion of container 10 and extend downwardly and outwardly therefrom, adjacent its back side 10d to a position outside the vertical confines of the container.
Because container 10 becomes quite hot in normal use, baffle plate 26 has been mounted in contouring relation to container 10. Channel spacer 27 and bracket 28 are used to space the baffle plate 26 away from container 10, and to connect it thereto. The spacing between baffle plate 26 and container 10 allows air to flow freely therebetween, thereby keeping baffle plate 26 relatively cool compared to container 10. The center portion of the baffle plate 26 has a plurality of perorations 30 which function to supplement the air flow around and through the baffle plate 26. Insulated washers 29 are placed between the channel spacer 27, the bracket 28, and the baffle plate 26 to further eliminate the heat transfer from said container 10.
A pair of support channels 31 are mounted to baffle plate 26 and extend inwardly toward the front side 10c of container 10. Support channels 31 strengthen the baffle plate 26 so that the operator may use the baffle plate 26 as leverage if needed. However, the support channels 31 do not normally touch container 10 and therefore do not conduct appreciable heat to said baffle plate. Therefore, heat transfer to the baffle plate 26 is limited and the latter thereby functions as a heat barrier or safety shield for the operator and reduces the likelihood of any serious injuries.
Flange 32 is mounted to the top angling portion of container 10 on its back side 10d, and extends generally outward and normal thereto. Flange 32 functions as a catch mechanism for the main storage vat when the contents of container 10 are to be disposed of. Container 10 is simply positioned so as to hook onto the main storage vat by means of flange 32, and then by grasping the insulated axle handle 23, the operator can tip the container to a position such that the hot fats and greases will safely discharge through inlet port 11 into the interior of the storage vat.
It will be seen from above that the hot fat transport vehicle provides a stable storage receptacle and container for hot fats and greases while in its upright position. It is further apparent that our invention provides a more effective, and safe means for receiving, transporting, and disposing of hot fats and greases normally collected by commercial restaurants than has been available in the past.
In considering this invention it should be remembered that the present disclosure is illustrative only, and the scope of the invention should be determined by the appended claims.
