Truck tire cattle feeder
This application is a continuation in part of Ser. No. 08/196,655 filed Jun. 6, 1994, now abandoned. 
    
    
     BACKGROUND OF THE INVENTION 
     The invention relates to agricultural equipment and, more particularly, pertains to mineral feeders for cattle. 
     DESCRIPTION OF THE PRIOR ART 
     Prior art mineral feeders are of several types and designs with each having one or more faults that limit their serviceability. 
     Instability and lack of durability results from a high center of gravity and being constructed from light weight material. Replacing spilled mineral and torn up mineral feeders is an expensive problem for cattlemen. 
     The useful life of prior art mineral feeders is limited by rust and corrosion of metal parts that are in contact with salt which is necessary in the diet of cattle. 
     Some prior art mineral feeders allow only one cow to eat at a time. This can deprive some cattle of an opportunity to eat minerals. 
     The present invention overcomes faults of prior art by utilizing P.V.C. plastic and used truck tires bolted together with bolts, nuts and washers made of stainless steel. These materials resist rust and corrosion. 
     The weight, flexibility and durability of truck tires makes it possible to have a low center of gravity and shock absorbing strength to cope with abuse received from cattle butting the mineral feeder. The low center of gravity increases stability of the feeder so that cattle can not turn it over. This stability supplies support for a large flat roof instead of a small bonnet shaped roof that limits access to mineral to one animal at a time. 
     SUMMARY OF THE INVENTION 
     It is an object of the invention to provide a movable mineral feeder that will allow cattle access to minerals while protecting the mineral from spilling and rain. 
     A further object of the invention is to provide the most durable and serviceable mineral feeder at the lowest cost. This is accomplished by utilizing used truck tires as the major building component. 
     In actual farm tests this feeder has proven to be durable and serviceable thus solving one of the problems confronting the dairy and beef cattle industry while recycling used truck tires. 
    
    
     BRIEF DESCRIPTION OF THE DRAWINGS 
     The present invention will be more fully understood by reference to the following detailed description thereof when read in conjunction with the attached drawings, and wherein: 
     FIG. 1 illustrates a front view of the mineral feeder; and 
     FIG. 2 illustrates a side view of the mineral feeder; and 
     FIG. 3 illustrates a back view of the mineral feeder. 
     FIG. 4A and 4B illustrates the assembly of the mineral feeder. 
    
    
     DETAILED DESCRIPTION OF THE DRAWINGS 
     FIG. 1 which illustrates a front view of the mineral feeder shows the position of tire 1 and tire 2 to form the base. The roof 11 is comprised of metal roofing material 8 fastened to steel frame 6. 
     FIG. 2 which illustrates a side view of the mineral feeder including the support of roof 11 by tire 3 and angle iron roof support 4. Brace 5 is bolted to roof frame 6 and angle iron roof support 4. 
     FIG. 4A illustrates the assembly of the feeder shows a circular piece of 1/8 inch thick sheet P.V.C. plastic 9 being placed between tire 1 and tire 2 of the base. Bolts, washers and nuts which are made of stainless steel comprise multiple fastening devices 7 that passes through the upper sidewall of tire 1, a circular piece of 1/8 inch thick sheet P.V.C. plastic 9, and the lower sidewall of tire 2. Tire 2 becomes an open top mineral container when part of the upper sidewall and rim bead is cut away. 
     FIG. 4B illustrates fastening devices 7 fastening angle iron roof support 4 to tire 3 and tire 1 near weld 10. Also angle iron roof support 4 is shown being fastened to tire 2 and tire 3 with fastening devices 7.
