Abstract: A portable pitching mound with a plurality of mound sections. The plurality of mound sections are assembled by inserting a lower edge of one mound section into a receiving slot of another mound section. The configuration of the receiving slot forms an opening larger than the lower edge of the mound section to be received therein. The larger size of the opening allows the lower to be positioned anywhere above the opening of the receiving slot and upon lowering the weight of the mound section and gravity causes the lower edge to slide downwards and towards the adjoining mound section. Assembly does not require any tools or connection members such as screws, bolts, clamps, clasps, pins, adherent or adhesive surfaces, or the like.

Abstract: A portable pitching mound having a base with a lower peripheral edge that is flush to the ground and an arcuate cross section to form a shell. A warning mat is attached to at least a portion of the base. Attached to the base and covering the warning mat is a layer of frictional material.

Abstract: A portable pitching mound having a plurality of shell pieces. Each shell piece has a forward and rearward end with opposite side portions and an upper surface and opposite underside. The shell pieces when placed side by side interlock to one another to form an arcuate shell member. At least one of the plurality of shell pieces have retractable wheels secured therein such that the shell piece is moveable to facilitate transportation.

Abstract: A portable pitching mound having a plurality of shell pieces that when placed in side by side relation form an arcuate shell member. Each individual shell piece has an interlocking means so that each shell is attached to an adjacent shell. Once all of the shell pieces are in side by side relation, a centrally located supporting cap is attached to the rearward end of each of the plurality of shell pieces to provide additional support.

Abstract: A method of identifying perimeter markings for lines on athletic fields involves locating two or more perimeter points on a line of an earthen athletic field comprising a ground surface; drilling a vertical hole in the earth in said points; placing a flexible elongated marking rope with a ground anchor on one end thereof longitudinally into each of the holes so that the ground anchor is in the lower end of the hole, and so that the upper portion of the rope extends from the hole above the ground surface. Loose material, such as loose dirt, is packed into the hole around the rope whereupon the upper portions of the ropes above the ground surface will serve as visible indicators of the location of the points. The rope is a plastic rope of polyethylene or the like which is six to eight inches long. It has a ground anchor on one end.

Abstract: A soil top dressing resulting from the method of taking a quantity of sand comprised of a plurality of sand particles; coating the sand particles with a liquid plasticizer material comprised of a mixture of water and at least one from the group of polyvinyl alcohol, polyvinyl acetate, silicon rubber latex or glycerol, adding a quantity of clay comprised of a plurality of clay particles, along with a quantity of the plasticizer material to the coated sand particles; adding a quantity of kelp to coat said sand coated particles; and coating the kelp with calamovilla longifolia.

Abstract: A portable pitching mound includes a generally convex body member having detachably securable front and rear portions. The rear portion has top and bottom surfaces with a peripheral edge extending therebetween. The front portion is detachably secured to the rear portion along a portion of the peripheral edge. The front portion has a top surface that includes a hollow for receiving a dense soil mixture to make a realistic, yet portable pitching mound.

Abstract: A soil top dressing is comprised of a mixture of sand, clay, a plasticizer material, water, and a coloring pigment, if desired. The components of the soil composition are preferably present in the following proportions by weight: sand 50-70%; clay 10-40%; plasticizer 0.5-5.0%; water 5-20%; coloring pigment 1-5%; all coated with kelp meal granules (5-20%). The method of making the invention involves continuously mixing a portion of the sand and the plasticizer in an agitation mixer. The sand becomes coated with the plasticizer, whereupon a quantity of clay is then added, followed by an additional portion of the plasticizing material. It is particularly important that the sand particles become coated with the plasticizing compound and clay. The coloring pigments are added and mixed thereafter. The foregoing particles are thereupon coated with particles of kelp meal. As soon as complete mixing takes place, material can be immediately transferred from the mixer to suitable packaging.

Abstract: A portable pitching mound is disclosed which is comprised of a concave horizontally disposed shell member which has a pitching rubber area. A first receptacle is indented into the surface of the shell member and is located immediately forwardly of the pitching rubber. A second indented receptacle portion is located in the forward portion of the shell member. A quantity of earthen material is located in each of the indented receptacle portions, and the earthen material is graded to conform to the contour or shape of the shell member.

Abstract: A portable arcuate shell member supported by its peripheral edge. A pitching rubber is mounted centrally thereof. A depression area extends from the pitching area forwardly from the rubber to the forward end of the shell member. A plate member is detachably secured to the depression area. A layer of resilient cushion material is secured to the plate member, and a layer of turf material is secured to the cushion material. A strip of friction material is secured to the peripheral edge of the shell member.
