(7) Conjunctions and combinations of conjunctions (e.g. “and/or”) are used herein when reciting elements and characteristics of embodiments; however, unless specifically stated to the contrary or required by context, “and”, “or” and “and/or” are interchangeable and do not necessarily require every element of a list or only one element of a list to the exclusion of others.

(8) Terms of degree, terms of approximation, and/or subjective terms may be used herein to describe certain features or elements of the invention. In each case sufficient disclosure is provided to inform the person having ordinary skill in the art in accordance with the written description requirement and the definiteness requirement of 35 U.S.C. 112.

(9) Referring now to the drawings wherein the showings are for purposes of illustrating embodiments of the invention only and not for purposes of limiting the same, FIG. 1 is a front view of embodiment 100. A vertically mountable base 102 is shown having certain components mounted on its surface. Particularly, two rotatable discs 104 are shown in two different rotatable mounting configurations, Configuration A and Configuration B. In both Configuration A and Configuration B, the rotatable disc 104 has a first circular face 104a and an opposing parallel second circular face 104b (out of view). Also in both configurations, the rotatable disc 104 has a circumferential surface 104c between the first and second circular faces 104a, 104b. The rotatable disc 104 may be solid or hollow as a matter of design choice. Without intending to limit the rotatable disc to any particular structure, one suitable component from which to fabricate a rotatable disc is a hockey puck.

(10) The difference between Configuration A and Configuration B is in how the rotatable disc 104 is rotatably mounted to the vertically mountable surface 102. In Configuration A, a centrally located axis of rotation 104x extends through a diameter of the rotatable disc 104 in parallel alignment with a central aperture 104p. The person having ordinary skill in the art will understand that the centrally located axis of rotation 104x is a logical mathematical abstraction and not a physical component of the embodiment 100. Further, as used here and throughout the specification and claims, the term “central” or “centrally located” refers to a center of mass. Accordingly, the centrally located axis of rotation 104x passes through a center of mass of the rotatable disc, bisecting the rotatable disc 104 into equal halves. Moreover, the centrally located axis of rotation 104x does not change or move relative to the vertically mountable base 102, meaning the axis of rotation 104x is in a fixed angular orientation relative to the base 102.

(11) In embodiments having a solid rotatable disc 104, the central aperture 104p comprises a single through-hole starting at a central opening in the circumferential surface 104c, passing through the disc, and ending in a second diametrically opposed central opening in the circumferential surface. In contrast, in embodiments having a hollow rotatable disc, the term “central aperture” means a pair of diametrically opposed openings in the circumferential surface 104c. In either case the central aperture 104p receives an axle 106 therethrough, about which the rotatable disc is free to rotate.

(12) The axle 106 fixedly cooperates with the vertically mountable surface 102, meaning the axle 106 remains stationary relative to the vertically mountable surface 102, through a direct or indirect mechanical communication, while leaving the rotatable disc 104 free to rotate about the axle 106. The axle may directly connect to the vertically mountable surface 102 or it may connect to it through one or more intervening structures. In Configuration A of the embodiment 100, such an intervening structure is shown as circumferential mounting brackets 108a, and 108b. The first bracket 108a receives a first end 106a of the axle 106 in a fixedly mounted relation according to any suitable known means as the ordinarily skilled artisan is capable of selecting as a matter of design choice and without undue experimentation.

(13) For example, and without limitation, the first bracket 108a may receive the first end 106a of the axle 106 in an interference fit, thus holding the axle 106 stationary relative to itself 108a. Alternatively, any of a wide variety of known means may be used such as, without limitation, cotter pins, press fitted end caps, threaded nuts, or one or more ends 106a, 106b of the axle 106 may be formed to a polygonal or star shape fitted to a complementary opening in the brackets 108a, 108b or, for instance, in a bushing fitted in the brackets 108a, 108b. The person having ordinary skill in the art will readily appreciate that only one end of the axle 106 must be fixedly mounted to a circumferential mounting bracket 108a or 108b. The other end of the axle may or may not be fixedly mounted while still achieving the same result, namely, to hold the axle 106 stationary while the rotatable disc 104 rotates about the axle 106. Thus, one end (106a or 106b) of the axle 106 may be mounted to the vertically mountable base 102 without being fixedly mounted, provided that the other end is fixedly mounted to the vertically mountable base 102.

(14) The circumferential mounting brackets 108a, 108b may take any suitable form provided they fixedly mount to the axle 106 at one end and to the vertically mountable surface 102 at an opposing end. As used here, the term “fixedly mount” includes mounting directly or indirectly, and also includes mounting brackets 108a, 108b that are unitary with the vertical mounting surface 102, such as by comprising a single molded part. One important limitation of the circumferential mounting brackets 108a, 108b is that they must provide sufficient clearance between the rotatable disc 104 and the vertically mountable surface 102 to allow the rotatable disc 104 to rotate a full 360 degrees about the axle 106.

(15) With continuing reference to Configuration A of FIG. 1, a follow-through landing wedge 110 is positioned below the rotatable disc 104 on the vertically mountable base 102. The landing wedge 110 includes a landing apex 110a. Similar to other components taught herein, the landing wedge 110 may be mounted to the vertically mountable base 102, directly or indirectly, or it may be unitary with the base 102, for example, by comprising a single molded part.

(16) Configuration A, is particularly suitable for training a pitch where the pitcher provides backspin to the baseball, as in a fastball. The pitcher uses Configuration A by placing his fingers on the top edge of the circumferential surface 104c of the rotatable disc 104 and spinning the top edge toward himself. Proper follow-through is trained by requiring the pitcher to land his hand on the landing wedge 110 such that his hand finishes with the landing apex 110a between his second and third fingers, i.e. his middle finger and ring finger.

(17) Configuration B, is suited for training the changeup pitch. The pitcher places his fingers at the top edge of the circumferential surface 104c and spins the rotatable disc 104 by moving his hand into a thumbs down position. Proper follow-through is trained by requiring the pitcher to land his hand on a vertical surface (112L1 or 112L2) of the follow-through landing 112.

(18) With continuing regard to Configuration B of FIG. 1, the rotatable disc 104 is shown rotatably mounted to the vertically mountable base 102 through a central aperture 104p in a first circular face 104a. An end 106a of an axle 106 is shown. The other end 106b is out of view, but is fixedly mounted to the vertically mountable base 102 either directly or indirectly through one or more intervening structures. As in Configuration A, the rotational axis (not shown) coinciding with the axle does not move or change relative to the vertically mountable surface 102, thus the axis is in a fixed angular orientation relative to the vertically mountable surface 102.

(19) Turning to FIG. 2, the embodiment 100 of FIG. 1 is shown in FIG. 2 from a side view. More specifically, Configuration A is shown from the side. The rotatable disc 104 is shown tilted slightly forward to show its direction of rotation, which is further illustrated by the arrows above and below the rotatable disc 104. Circumferential mounting bracket 108a is shown providing sufficient clearance between the rotatable disc 104 and the vertically mountable surface 102 to allow full rotation of the rotatable disc 104. The follow-through landing wedge 110 is shown beneath the rotatable disc 104 with its apex 110a directed toward the rotatable disc 104. An example mounting J-bracket 202 is also shown to illustrate how the vertically mountable surface may be mounted. The person having ordinary skill in the art is capable of selecting known mounting brackets, as well as their number and placement, as a matter of design choice. It is contemplated that the embodiment 100 may be mounted to a wall or fence at an end of a dugout so that the pitcher may practice between innings.

(20) Turning to FIG. 3, the embodiment of FIGS. 1 and 2 is shown from an alternate side view revealing selected structures of Configuration B. particularly, the axle 106 is shown rotatably mounting to the vertically mountable surface 102 through a support bracket 306. More specifically, the first end 106a of the axle 106 is shown in an interference fit with the support bracket 306, which in turn is mounted to the vertically mountable base according to known means not shown but discussed elsewhere herein. The axle 106 is thus in a fixed angular relation to the vertically mountable base 102 and is also held stationary by, e.g. the interference fit. The second end 106b of the axle receives the rotatable disc 106 through a central aperture 104p. The rotatable disc 104 is free to rotate about the axle 106, and is retained on the axle 106 by an end stop 304. The ordinarily skilled artisan will readily understand how to fabricate an end stops 304 without further explanation; however, for example and without limitation, an end stop 304 may be a cap crimped onto the axel, or a flare of the axle in the nature of a nail head. Optionally, a washer 302 may be interposed between the rotatable disc 104 and support bracket 306. Similarly, a washer may be interposed between the rotatable disc 104 and the end stop 304, though none is shown in the illustrated embodiment.

(21) While Configurations A and B are shown here as integrated into a single embodiment, this is not a limitation of the invention. Embodiments may include either Configuration A or Configuration B, or both without departing from the scope of the invention.
