The present technology broadly relates to enhancing performance of bats. More specifically, this technology relates to enhancing hitting performance of baseball bats by compressing a bat barrel.
Baseball bats include several parts. The end furthest from the grip may include a cup, which is a circular indentation intended to make the bat lighter without losing striking surface. The Official Rules of Major League Baseball Rule 1.10 allows the barrel or striking surface of a bat to be dimensioned to not more than 2.61 inches in diameter. The rules permit a barrel diameter as small as 2¼ inches. Other divisions such as college, high school, and youth divisions allow different bat dimensions. The barrel may extend at a selected diameter for approximately ⅓ the length of the bat. The barrel includes a sweet spot that is ideal to hit the ball. Typically, wooden bat manufacturers mark the surface of a bat that faces upward while the bat moves through the strike zone with a logo. The logo is generally positioned somewhere between the sweet spot on the barrel and the handle area. Batters typically swing bats made from ring bar wood such as Ashe so the grain is parallel to the motion of the bat. In contrast, batters typically swing bats made from diffuse core wood such as Maple so the grain is perpendicular to the motion of the bat. These bat orientations ensure that the strongest side of a bat contacts a baseball. The bat barrel tapers down to a narrow handle for gripping by a batter. The handle terminates in a small swelling called a knob, which helps prevent the bat from slipping out of the batter's hand during a swing. Most batters grip the bat so the knob touches the bottom of their hand. Other batters wrap the bottom of their hand around the knob.

Baseball is a bat-and-ball sport played on a field between two teams that take turns batting and fielding. The objective of the offensive team (batting team) is to hit the ball into the field of play, away from opposing players, to allow the offensive players to run the bases to score “runs.” Baseball bats are manufactured from billets and generally include an overall length, a knob provided at a first end proximate to a grip area, a barrel, and a barrel end provided at a second end that is opposite to the first end. Players swing the baseball bat to strike a baseball. The technology described herein imparts a higher compressive strength and improved surface hardness to the bat, specifically the barrel. This results in the bat transferring a greater impact force onto the baseball, which generally results in a faster exit velocity for a ball hit with a bat. A faster exit velocity translates into a greater distance travelled by the baseball. In contrast, bats having less compressive strength and/or less surface hardness absorb an impact force, which generally results in a slower exit velocity for a ball hit with a bat. A slower exit velocity translated into less distance travelled by the baseball.
According to one example, the compressing tool 106 may include an implement 108 that mechanically compresses selected portions of wooden baseball bats 104. According to one example, the implement 108 is configured to pivot. For example, the implement 108 may pivot along a lengthwise dimension to allow the implement 108 to substantially match an angle of an underlying bat barrel 107. In other words, the implement 108 may pivot in a lengthwise direction to substantially match a surface angle of the underlying bat barrel 107 in a lengthwise direction. According to one example, the implement 108 may include a roller 111 that contacts selected portions of the wooden bat 104 during a compressing operation. For example, the roller 111 may contact a bat barrel 107 during the compressing operation. According to one example, the roller 111 may be sized in a lengthwise dimension to correspond to a surface shape of the underlying bat barrel 107. For example, if the underlying bat barrel 107 includes a substantially flat section that extends 4-inches in a lengthwise direction, then the roller 111 may be sized to extend substantially 4-inches in a lengthwise direction. One of ordinary skill in the art will readily appreciate that the roller 111 may be sized with larger or smaller dimensions as desired.
According to one example, the roller 111 may include a surface having any desired surface contour such a convex surface contour, a concave surface contour, or the like. According to one example, the compressed surface of the wooden bat 104 may substantially assume the shape of the roller surface contour. With reference to
According to one example, the roller 111 may be constructed from any material that compresses a wooden surface. For example, the roller 111 may be constructed from a ceramic material or other material that has a harder surface than wood. According to one example, the compressing tool 106 may be coupled to a carriage 113. According to one example, the compressing tool 106 may apply a compressing force to the implement 108 that transfers the compressing force onto a surface of the wooden bat 104 through the roller 111. According to one example, the carriage 113 may slide the compressing tool 106 along tracks 114 to any desired position along a length of the wooden bat 104. According to one example, a cylinder 115 provided on the compressing tool 106 may actuate the implement 108 to compress a surface of the bat 104. According to one example, the carriage 113 with the compressing tool 106 may be positioned at any desired spot along a lengthwise portion of the bat 104. For example, the carriage 113 with the compressing tool 106 may be positioned at any desired spot along a lengthwise portion of the bat 104 prior to the compression operation.
According to one example, the cylinder 115 may press the compressing tool 106 against a surface of the barrel 107. According to one example, the bat 104 may be supported within the device 100 by a bat support 109 and clamp 110. According to one example, the device 100 may include a rotator 112 that rotates the bat 104 about its length axis. According to one example, the rotator 112 may be programmed to rotate the bat 104 a full 360 degree about a lengthwise axis. Alternatively, the rotator 112 may be programmed to rotate the bat 104 a specific number of degrees about its lengthwise axis to complete a desired amount or degree of rotation of the bat 104. According to one example, the bat 104 may be initially oriented within the device 100 with a bat label facing upward.
According to one example, the device 100 may be configured to compress the barrel 107 in the latitudinal or circumferential direction to increase the compressive strength or surface hardness of the bat 104. According to one example, the compressing tool 106 may employ a ceramic material that applies a downward or compressing force onto the surface of an underlying wooden bat 104. According to one example, the compressing tool 106 may control surface compression to provide repeatable results. According to one example, the compressing tool 106 allows application of controlled pressure that may be varied at different positions along a circumference of the barrel 107. In other words, the controlled pressure may be varied in at different positions along a latitudinal direction of the barrel 107. Furthermore, the rotator 112 allows different increments or amounts of bat rotation to enable precise control during the compressing operation. According to one example, a servo motor 116 may drive the rotator 112. According to one example, the servo motor 116 may be coupled to a computer that sends a signal to spin the rotator 112 by a selected angle. According to one example, the rotator 112 may provide different increments of rotation speed. For example, the rotation speed may be constant or variable.
According to another example, the device 100 is configured to compress a surface of the barrel 107 to contour or shape the surface of the bat 104. According to one example, the compressing tool 106 may employ a ceramic material that applies a compression force to the surface of wooden bats 104. According to one example, the compressing tool 106 provides control over surface compression to provide repeatable results. Furthermore, the compressing tool 106 may be programmed to maintain bat dimensions within desired tolerances. For example, the compressing tool 106 may be programmed to maintain a diameter of the barrel 107 within tolerances permitted by Major League Baseball or other governing bodies.

According to one example, the barrel 201 may be custom shaped to account for idiosyncrasies of a batter. According to another example, the barrel 201 may be custom shaped to account for individual swing characteristics of a batter. For example, the barrel 201 may be custom shaped to increase a likelihood that the surface of the barrel 201 is square to a target upon impacting a baseball. Alternatively, the barrel 201 may be custom shaped to push baseballs in a desired direction. In this way, a batter may own several bats that increase the probability of steering the ball to a desired area on the field.
According to one example, the barrel 201 may be shaped as illustrated in
According to one example, bat characteristics are impacted by bat manufacturing processes including cutting, rough sanding, boning, filler additive, finish sanding, and paint finishing, among other manufacturing processes. Boning is a process in which an implement is rubbed along a bat barrel in the longitudinal or lengthwise direction while the bat is rotated at a high rate of speed. The technology described herein provides post-manufacturing processing to increase bat compressive strength and surface hardness, among providing other benefits. Bat compressive strength is the capacity of the wood to withstand compression forces such as when the bat 104 is hit with an object such as a baseball. Surface hardness refers to the resistance of wood to denting. Bats made from softer woods such as birch have less compressive strength and therefore absorb an impact force, resulting in less impact force transferred to a baseball. In contrast, bats made from harder woods such as maple have more compressive strength and transfer more impact force when impacting a baseball. Generally, baseballs travel further when hit with bats having higher impact forces.
Referring to
According to one example, the rebound hammer 122 is oriented at a substantially right angle to the surface of a material for conducting a test. For accurate results, the material surface contacted by the rebound hammer 120 should be flat and smooth. Given the curvature of the surface of a baseball bat 104, the rebound hammer 120 may include a v-block tool 124 mechanically affixed to the end of a plunger or rod 125. According to one example, the v-block tool 124 may be dimensioned to dissipate or spread an impact force of the rebound hammer 120 over an area that is larger than the surface area of the end of the plunger 125. According to one example, the impact force is spread to reduce a likelihood that the rebound hammer 120 will deform a surface of the bat 104 during testing.
According to one example, the rebound hammer 120 may be employed to obtain a plurality of reading. According to one example, the highest and lowest readings may be dropped. According to one example, twelve readings may be taken, with the highest and lowest readings dropped. According to one example, the remaining readings may be averaged. This testing method is indirect since the test does not provide a direct measurement of the strength of the material. According to one example, the testing method provides an indication based on surface properties. According to one example, the rebound hammer 120 may be actuated with an air cylinder multiple times to obtain readings of the compressive strength of the barrel 107. One example of a rebound hammer is a Schmidt #OS8200L.
According to one example, a handle 130 provided at the carriage 113 may be employed to position the compressive strength measurement tool 120 over a desired location on the wooden bat 104. According to one example, the carriage 113 may slide the compressive strength measurement tool 120 along the tracks 114 to align with any position along the wooden bat 104. According to one example, the handle 130 may be provided to manually guide the compressive strength measurement tool 120 along a lengthwise direction of the bat 104 or barrel 107. One of ordinary skill in the art will readily appreciate that an automated mechanism may be provided to move the compressive strength measurement tool 120 along a lengthwise direction of the bat 104 or barrel 107 under control of a computer.
With reference to
According to one example, the devices 100,400 are configured to compress a surface of the barrel 107 to increase compressive strength or bat surface hardness. According to one example, the devices 100,400 may employ a ceramic material that applies compressing forces to the surface of wooden bats 104. According to one example, the compressing tool 106 provides control over surface compression and offers repeatable results. The compressing tool 106 provides an effective way to uniformly “break in” a bat 104 using a machine that compresses the barrel 107. One benefit of the compressing tool 106 is that the wood surface may be compressed all around the barrel 107. In contrast, batters typically “break in” their bats by hitting over 50 baseballs, which is a time-consuming process and only compresses the hitting surface of a bat 104 where each ball contacts.
According to one example, the compressing tool 106 may be programmed to maintain bat dimensions within tolerances. According to one example, the compressing tool 106 may be programmed to apply a controlled amount of pressure along the length of the bat 104. According to one example, the compressing tool 106 may vary the applied pressure at different positions along the barrel 107 of the bat 104. According to one example, the rotator 112 may precisely rotate the bat 104 during compression by allowing different increments of rotation.
From the foregoing it will be appreciated that, although specific examples are described herein for purposes of illustration, various modifications may be made without deviating from the spirit and scope of this disclosure. For example, the methods, techniques, and systems for the shaping baseball bats are applicable to other settings.
While the preferred example of the technology is illustrated and described, as noted above, many changes can be made without departing from the spirit and scope of the invention. Accordingly, the scope of the invention is not limited by the disclosure of the preferred example.
