INSTRUCTIONAL DEVICE FOR USE IN CONNECTION WITH BALL GAMES Filed Oct. so, 1953 i nwe/vm All/452 Ahm a United States Patent INSTRUCTIONAL DEVICE FOR USE IN CONNECTION WITH BALL GAlVIES Minden Vaughan Blake, London, England Application October 30, 1953, Serial No. 389,383
Claims priority, application Great Britain November 12, 1952 7 Claims. (Cl. 273-186) This invention relates to instructional devices for teaching the correct arm and body movements in ball. games employing clubs, bats, rackets or the like, and has for its object to provide a device which will indicate the position in the swing when the club or the like attains or would attain its maximum angular velocity, and give the feel of having hit a ball.
While this invention may be appliedto many sports, it may most readily be understood in its application to driving-strokes of golf, which will now be described.
A good driving-stroke is made up of a steady acceleration of the club by the arms and body on the downward part of the stroke, followed by a rapid acceleration of the club by the wrists at the bottom of the stroke when the ball is hit, and culminating in a relaxed follow-through, the point of maximum angular velocity of the club being when the club head is in contact with the ball.
A common fault is that players give theclub the rapid acceleration with the wrists too early in the stroke, and
strike the ball in that part of the stroke which should be the relaxed follow-through, when the angular velocity of the club has passed through its maximum point and the grip on the club has slackened.
According to this invention, a device for discovering the way in which a player swings a club, bat, racket or the like comprises a handle, an extension 'of the handle, a weight mounted on the extension and movable towards and away from the handle, a movable stop to obstruct the weight from moving away from the handle, and a control for the stop operative to move it so as to release the weight when the handle and extension attain a particular angular velocity.
According to a feature of the invention, the extension may be parallel sided and extend coaxially with the handle e. g. a cylinder extending coaxially with the handle and the weight maybe a ring which is slidably mounted on the extension. Whenthis feature is adopted, the movable stop may be provided by at least one member which projects above the surface of theextension when the angular velocity of the extension is less than that required to release the weight and which is withdrawn into the extension by the action of the control means when the angular velocity exceeds that requiredto release the weight.
In such a construction the extension may be hollow and have an axially extending slot in its wall, the control means for the projection may comprise a mass contained within the extension and slidable towards and away from the handle and a spring to urge the mass towards the handle, and the movable stop may comprise a member spring urged out through the slot when the member is appropriately located in the extension which member is connected to move with the mass, and has a surface inclined at a small angle relative to the axis of the device so that the member is withdrawn into the extension, as it moves away from the handle, by the inclined surface moving over the end of the slot remote from the handle.
Preferably the extension has two diametrically-opposed axially extending slots in its wall, and the movable stop comprises two arms spring-urged apart so that one end "ice of one arm projects through one slot and one end of the other arm projects through the other slot when the arms are appropriately located in the extension each of which arms is pivoted at its other end to the mass, and each of whicharms has a surface which, when the arms project through the slots, is inclined at a small angle relative tolthe axis of the device, so that each arm is withdrawn into the extension, as it moves away from the handle, by the inclined surface moving over the end of its slot remote from the handle.
Movement of the mass towards the handle may be limited by a fixed stop within the extension, and if this is done the spring urging the mass towards the handle may load the mass against the fixed stop when the device is ready for use. The initial load of the spring loading the mass against the fixed stop when the device is ready for use may be adjustable. For instance; the extension may be open at its end remote from the handle and screw-threaded at that end to receive a closing member, and the spring to urge the mass towards the handle may abut between the closing member and an abutment on the mass, the initial load on the mass being adjusted by screwing the closing member on the extension.
The closing member may be a cup with a central aperture and the mass may be a rod-like member which extends through the aperture and is guided thereby.
The device may also comprise a fixed stop projecting from the surface of the extension and located so as to limit the movement of the weight away from the handle, a second fixed stop projects from the surface of the extension and is arranged to limit the movement of the weight towards the handle.
According to another feature of the invention the device may be constructed to be mounted on or in an actual club, bar, racket or the like.
According to yet another feature of the invention the device may be mounted only by a handle so'that the swing may be practised in a con-fined space such as a room.
One embodiment of the invention and a modification thereof will now be described with reference to the accompanying drawings in which:
Figure 1 is an axial section through the device.
Figure 2 shows a view of a modified rod member.
Figure 1 shows a device, according to the invention, for practising golf-strokes in confined spaces which comprises a handle 10 having a cylindrical tubular member 11 co-axially secured to it. The tubular member 11 has the end remote from the handle enlarged and tapped to enter into a closing cup 12. The cup 12 has an axial bore which acts as a guide for a rod-like member 13 which can' slide axially inside the tubular member 11, but is urged towards the handle 10, against an internal stop 14 in the tubular member 11, by a helical spring 15 compressed between an abutment 16 on the rod-like member and the closing-up 12. The rod-like member 13 has two arms 17 pivotally mounted on it at locations spaced from the abutment 16 towards the handle. A light helical spring 18 between the two arms 17 urges them apart so that the shoulders 22 on them project through two diametrically opposed, axial slots 19 in the tubular member 11, when the rod-like member 13 is held against the internal stop 14.
A weight 20 in the form of a solid ring is slidably mounted on the tubular member 11. Movement of the ring 20 towards the handle is limited by a stop 21 secured to the tubular member between the axial slots 19 and the handle 10 so that the ring 20 can lie between it and the shoulders 22 of the two arms 17 projectingthrough the axial slots 19. Movement of the ring 20 away from the handle is limited by a stop 25.
When the device is swung by the player, centrifugal force on the rod-like member 13 moves it axially against the helical spring 15, and when it has travelled a certain distanceycorresponding to a certain angular velocity of the device, the projecting shoulders 22 are retracted into the tubular-member 11 and the ring'20 flies on until it abuts a second fixed stop 25 causing the centre of inertia ofthe club to move outwardsand giving the impression of having hit a ball. It also makes a distinctive sound,
so that the position of the player when the ring 20 flies 4 member 13 has an extension 23 which extends through a central aperture 24 in the closing-cup 12 which thereby acts as an additional guide for the rod-like member 13.
I claim:
