Description
- This invention relates generally to practice aids for baseball and similar games, and more particularly to pitching and ball throwing machines therefor.
- In practicing the games of baseball and softball, it is often necessary to project a ball repetitively in a high, arcing trajectory. For example, it may be desired to simulate “high fly balls” or “pop-up balls” hit by a batter. As used herein the term “high, arcing trajectory” refers to a ball flight path which initially extends at a high angle to the surface of the Earth and has a substantial vertical component, as opposed to a “low” trajectory ball flight path, which initially extends at a low angle to the surface of the Earth and has a lesser vertical component. While the terms “high” and “low” are relative, it will be understood that baseball players and coaches have an accepted understanding of the distinction between a “low” trajectory, as would occur in a ball thrown from a pitcher to a batter, or in a “line drive” hit by a batter, and a “high” trajectory, as would occur in “high fly balls” or “pop-up balls” hit by a batter.
- The type of high, arcing trajectory needed for fielding practice is difficult for a coach to simulate. The coach must either throw the balls or hit them to the fielders with a bat. Either process produces inconsistent results and is tiring.
- Various types of ball throwing machines (also referred to interchangeably as “pitching machines”) are known. Such machines utilize a mechanical or electrical mechanism to propel a ball. Known pitching machines are consistent and alleviate the need for physical effort. However, pitching machines are optimized for simulating pitches to a batter, and are therefore not capable of producing the high, arching trajectory needed for fielding practice, even when set to a maximum angle adjustment.
- Accordingly, there is a need for a machine that can mechanically throw balls having a high, arcing trajectory for fielding practice.
- This need is addressed by the present invention, which provides a base that receives and supports a conventional ball throwing machine. The base has an adjustable elevation angle and enables the ball throwing machine to produce high arcing ball trajectories.
- According to one aspect of the invention, a base is provided for a ball throwing machine having a T-shaped frame. The base includes: a lower frame; an upper frame pivotally connected to the lower frame so as to be moveable through a range of elevation angles relative to the lower frame, and including one or more brackets configured to receive the T-shaped frame of the throwing machine; and an adjustment mechanism configured to releasably secure the upper frame at a selected elevation angle within the range.
- According to another aspect of the invention, a ball throwing apparatus includes: a ball throwing machine having a T-shaped frame, with means for throwing a ball mounted thereon; and a base, including: a lower frame; an upper frame pivotally connected to the lower frame so as to be moveable through a range of elevation angles relative to the lower frame, and including one or more brackets that secure the T-shaped frame of the throwing machine to the upper frame; and an adjustment mechanism configured to releasably secure the upper frame at a selected elevation angle within the range.
- According to another aspect of the invention, a ball throwing apparatus includes: a ball throwing machine comprising a beam including forward and aft ends, the beam having with means for throwing a ball mounted thereon; and a base, comprising: a lower frame; an upper frame pivotally connected to the lower frame so as to be moveable through a range of elevation angles relative to the lower frame, wherein the upper frame includes: a transverse upper forward cross rail disposed at a front end of the upper frame, the upper forward cross rail having a threaded first fastener fixedly attached thereto; an aft bracket disposed at a rear end of the upper frame, the aft bracket defining a forward- facing pocket which receives the aft end of the frame; a threaded second fastener engaging the first fastener and the forward end of the beam, thereby holding the forward end of the beam against the upper forward cross rail; and an adjustment mechanism configured to releasably secure the upper frame at a selected elevation angle within the range.
- The invention may be best understood by reference to the following description taken in conjunction with the accompanying drawing figures in which:

FIG. 9 is a perspective view of an alternative configuration for attaching a ball throwing machine to a base; and -
FIG. 10 is a side view of a portion of the device shown inFIG. 9 . - Referring to the drawings wherein identical reference numerals denote the same elements throughout the various views,
FIG. 1 depicts an exemplary prior artball throwing machine 10 suitable for use with the present invention. This type of machine is commercially marketed as the UPM45 Pitching Machine, available from Louisville Slugger Training Aids, Erlanger, Ky. 41018 USA. While this machine is used as an example, it will be understood that the principles of the present invention are equally applicable to other types of ball throwing machines. - Before further description of the
ball throwing machine 10, it is noted thatFIGS. 1 and 2 depict an X-Y-Z coordinate axis. As used herein, unless otherwise stated, the terms “axial,” “longitudinal,” “front-rear,” and the like refer to dimensions or directions parallel to the X-axis. Unless otherwise stated, the terms “lateral,” “transverse,” “left-right,” and the like refer to dimensions or directions parallel to the Y-axis. Unless otherwise stated, he terms “vertical,” “up-down,” and the like refer to dimensions or directions parallel to the Z-axis. All of these relative directional terms are used herein for the purposes of description and explanation and do not necessarily imply that any particular orientation of components is required for the invention. - The
ball throwing machine 10 includes a T-shaped stationary frame with abeam 12 and acrossbar 14. In a typical model, thebeam 12 is secured to thecrossbeam 14 via a threaded bolt that incorporates ahand knob 15. In some commercially-available versions of this machine, the distal ends of thecrossbar 14 are not exactly horizontal, but instead extend downwards at an angle. A rear end of thebeam 12 includes arear foot 16 defined by a pad of rubber or other non-slip material, and distal ends of thecrossbar 14 also includefront feet 18 defined by pads of rubber or other non-slip material. Taperedmetallic spikes 20 may be mounted on the distal ends of thecrossbar 14 so that the frame can be secured into turf or topsoil. Afoot lever 22 is pivotally attached to thebeam 12. Anupright post 24 extends vertically from thebeam 12. Athrowing arm 26 is pivotally mounted to thepost 24. Thethrowing arm 26 is shaped to receive a ball (not shown) and includes aball stop 28. Amainspring 30 interconnects thefoot lever 22 and thethrowing arm 26. Arelease arm 32 is pivotally mounted to thebeam 12, and includes arelease bracket 34 shaped to engage the distal end of thethrowing arm 26. Collectively, the components mounted to the frame comprise means for throwing a ball. - To prepare the ball throwing machine for use, the
throwing arm 26 is rotated backward and therelease arm 32 is moved forward such that therelease bracket 34 engages the distal end of thethrowing arm 26, restraining it from forward motion. The relative dimensions of thepost 24,foot lever 22,throwing arm 26,mainspring 30, andrelease arm 32 are selected such that themainspring 30 applies a minimal tension, keeping thethrowing arm 26 engaged with therelease arm 32. - Next, a ball is placed on the
throwing arm 26 against theball stop 28. The user then presses down on thefoot lever 22 to extend and tension themainspring 30. When the user is ready, he pulls therelease arm 32 backwards, disengaging therelease bracket 34 from thethrowing arm 26. This frees thethrowing arm 26 to be driven forward under tension from themainspring 30, throwing the ball forward. -
FIG. 2 depicts an exemplary adjustablethrowing machine base 100 constructed according to an aspect of the present invention, suitable for mounting the type ofthrowing machine 10 shown inFIG. 1 and supporting it at varying elevation angles. - The
base 100 includes alower frame 102 which is configured to rest on the ground, and anupper frame 104 which is configured to receive and hold aball throwing machine 10. Theupper frame 104 is pivotally attached to thelower frame 102 so that it can be set at a variety of elevation angles relative to thelower frame 102 - More specifically, the
lower frame 102 includes two spaced-apart longitudinallower side rails 106. Eachlower side rail 106 includes afront bracket 108 at its forward end, comprising two spaced-apart flanges extending upward from thelower side rail 106, with a pair of coaxial holes formed therethrough. Eachlower side rail 106 also includes apivot bracket 110 at its aft end, comprising two spaced-apart flanges extending upward from the lower side rail, with a pair of coaxial holes formed therethrough. The forward and aft ends of thelower side rails 106 are interconnected by forward and aft lower cross rails, 112 and 114, respectively, so as to form a rectangular frame. - Optionally, the
base 100 may incorporate wheels or rollers to facilitate easy transport and positioning. In the illustrated example, awheel support arm 116 extends upward at an acute angle from the forward end of eachlower side rail 106. Awheel 118 is mounted for rotation near the distal end of eachwheel support arm 116, for example using the illustratedaxle bolts 120. Thewheel support arms 116 position thewheels 118 in such a way that they are held away from ground contact during normal use, but may be brought into ground contact by simply lifting up the rear end of thebase 100. - Each of the
front brackets 108 receives anadjustment post 122 which extends upward. Eachadjustment post 122 includes a mounting hole passing transversely through its lower end, and a series of spaced-apart adjustment holes 124 passing transversely therethrough. Theadjustment post 122 is pivotally attached to thefront bracket 108, for example using the illustratedbolt 126 passing through the mounting hole. - The
upper frame 104 includes two spaced-apart upper side rails 128. Eachupper side rail 128 includes anelevation bracket 130 at its forward end, comprising two spaced-apart flanges extending forward from theupper side rail 128, with a pair of coaxial holes formed therethrough. Eachupper side rail 128 also includes a mounting hole passing transversely through its aft end. The forward and aft ends of the upper side rails 128 are interconnected by forward and aft upper cross rails, 132 and 134, respectively, so as to form a rectangular frame. -
FIG. 3 illustrates the connection of theupper frame 104 to thelower frame 102 in more detail. The aft end of eachupper side rail 128 is pivotally connected to one of thepivot brackets 110 so that it can pivot in elevation, for example using the illustratedbolts 136. Theupper frame 104 is moveable through a range of nonzero, acute elevation angles relative to thelower frame 102. - Also, as seen in
FIG. 4 , the upper portion of eachadjustment post 122 is received in one of theelevation brackets 130. This arrangement allows theupper frame 104 to be pivoted up or down. As it is moved, theelevation brackets 130 slide along the adjustment posts 122. The adjustment posts 122 pivot forward or aft in order to remain in contact with theelevation brackets 130. Theupper frame 104 may is releasably secured at a desired height relative to theadjustment post 122. As used herein, the term “releasably secured” refers to a mechanism effective to secure theupper frame 104 to theadjustment post 122 which is intended and configured to be released on a regular basis, and which can be released by manual effort alone or with the minimal use of tools. For example, it does not involve substantial disassembly, cutting, or similar procedures. A latch, clamp, or readily-removable fastener could be used for this purpose. An example of a releasable securement would involve passing a pin or similar fastener through one of the adjustment holes 124 in the post and the matching holes in theelevation bracket 130. In the specific example illustrated, a conventional releasable pin 138 (often called a “hitch pin”) is used for this purpose, as it can be readily secured in place or released using thespring bail 140 that it incorporates. -
FIG. 2 shows theupper frame 104 secured in an intermediate position between upper and lower positions. The upper and lower frames define a first elevation angle “ε” (epsilon). Securing theupper frame 104 in higher or lower positions along the adjustment posts 104 will result in higher or lower elevation angles, respectively. - The
upper frame 104 is specially configured to receive and securely hold theball throwing machine 10 with a minimal amount of effort. Specifically, the forwardupper cross rail 132 includes two front mountingholes 141 which are sized and shaped to receive thespikes 20 of theball throwing machine 10. - A
forward bracket 142 is carried by eachupper side rail 128. Theforward brackets 142 are positioned to bear against the distal ends of thecrossbar 14. - An
aft bracket 144 is carried by the rearupper cross rail 134. It defines a pocket, facing axially forward, which receives therear foot 16 of thebeam 12 and restrains it vertically up and down, laterally left and right, and axially aft. In the illustrated example it is built up from a plurality of short segments of angle stock. - The base 100 may be constructed from any material that is rigid and will support the expected mechanical loads during use, for example metals, plastic, or wood. In the illustrated example, the components of the
base 100, such as the rails and brackets, are constructed from mild steel square-section tubing and steel sheet or bar stock, with the joints between components being welded together or connected using conventional mechanical fasteners. - Referring to
FIG. 5 , to mount theball throwing machine 10 to thebase 100, therear foot 16 is placed into theaft bracket 144 by sliding therear foot 16 axially aft into the aft bracket 144 (shown inFIG. 6 ). Thefront feet 18 are lowered so that thespikes 20 engage the front mounting holes 141. Theforward brackets 142 support the throwing machine against axial movements and yawing movements. The combination of the forward andaft brackets spikes 20 support theball throwing machine 10 against lateral, vertical, and axial movements. For all practical purposes, theball throwing machine 10 is completely rigid and stationary relative to thebase 100, yet it can be easily removed for transport or storage by simply reversing the mounting process. - Once the
ball throwing machine 10 is mounted to thebase 100, as shown inFIG. 7 , the base 100 can be placed in the desired position and direction by rolling it on thewheels 118. The elevation angle ε can be adjusted by raising or lowering theupper frame 104 as desired, using the process described above. Theball throwing machine 10 may then be used to project the ball in high, arcing trajectories needed for fielding practice, for example, long fly balls or pop-up balls. - As a option, means may be provided for further securing the
ball throwing machine 10 to thebase 100. For example,FIG. 8 illustrates a portion of thecrossbar 14 and theupper cross rail 132. Anelastic retaining strap 150, made of a material such as natural or synthetic rubber, is wrapped around the two members. Theupper cross rail 132 is provided with a fixed pin 152 (for example, thepin 152 could be welded to a front face of theupper cross rail 132 and protrude outward therefrom). The retainingstrap 150 has a row ofholes 154 formed therein. The retainingstrap 150 can be secured by placing one end over thepin 152, wrapping around the two members, and then securing the opposite end over the pin. Oneretaining strap 150 and pin 152 can be provided near each distal end of thecrossbar 14. One end of the retainingstrap 150 may be permanently left attached to thepin 152, and the opposite end simply hooked or unhooked from thepin 152 as required. The retaining straps 150 are helpful in preventing theball throwing machine 10 from bouncing out of engagement with theframe 100, when theframe 100 is being rolled over rough ground. - As an alternative to the mounting method described above, the
ball throwing machine 10 could be fastened directly to theupper cross rail 132. This may be desirable when a more permanent connection between theframe 100 and theball throwing machine 10 is desired. For example,FIG. 9 shows theball throwing machine 100 with thecrossbar 14 removed. The front end of thebeam 12 is then connected to theupper cross rail 132 using the bolt which is a part of theball throwing machine 10. -
FIG. 10 shows how theupper cross rail 132 could be modified for this mounting method. Anut 156 or other threaded fastener is secured to theupper cross rail 132 so that it cannot turn, for example by welding, swaging, or adhesive bonding. A hole (not shown) is formed through theupper cross rail 132, aligned with the bore of thenut 156. Thebeam 12 abuts theupper cross rail 132. The bolt (labeled 158) passes through thebeam 12 and engages the threads of thenut 156. Thebolt 158 can be tightened or loosened using thehand knob 15. - The foregoing has described a base for a ball throwing machine. While specific embodiments of the present invention have been described, it will be apparent to those skilled in the art that various modifications thereto can be made without departing from the spirit and scope of the invention. Accordingly, the foregoing description of the preferred embodiment of the invention and the best mode for practicing the invention are provided for the purpose of illustration only and not for the purpose of limitation.
