Abstract

The Over-arm Cricket Bowler is an action toy having mechanical parts so that it can be manipulated to bowl at cricket stumps and batsperson. The Bowler comprises head and shoulder section 45, torso section 44 and lower torso and leg section 43. Torso section 44 is hollowed-out and includes apertures 25, 40, 41 for cord wind shaft, spring retaining shaft and brake shaft respectively. A slot 42 (not shown) accomodates arm connecting shaft 2. The hand 48 has a cavity in which is fixed a small magnet 50 to retain a cricket ball of magnetisable material. The torso includes, in its hollowed-out portion, a spring (20, Figure 11) connecting spring retaining shaft 26 to arm connecting shaft 2. The spring can be tensioned so that, upon release of this tension, the bowling arm 47 will rotate at speed, thus propelling the cricket ball towards stumps and batsperson. <IMAGE>

Description

The Over-arm Cricket Bowler.

This invention relates to an action doll that can be operated by children and or adults.

The Over-arm Cricket Bowler is shaped to the basic human form and can be either male or female. It is fitted with internal and external mechanical parts; on shafts, which when manipulated will emulate a human over-arm cricket bowler.

According to the present invention. The Over-arm Cricket Bowler is able to bowl a ball in an over-arm bowling action at a set of three wickets; topped by a set of bails, placed in front of and within range of the power limitation of the Over-arm Bowler.

A specific embodiment of the invention will now be described by way of example with reference to theaccompanying drawing in which: Fig I shows the initial arm connecting shaft.

Referring to the drawing Fig20 The Over-arm Cricket Bowler is made up of three sectins, not including the arms.

The head and shoulder section 45 is. solid.

The middle torso section 44 is hollowed out and two arm connecting shaft slots 42 are cut out and down from the top edge.

The lower torso and leg section 43 has the thigh section -- between waist and crutch - hollowed out, and two apertures drill through both sides of the hollowed out section, these are, the cord winding shaft aperture 25 and the spring retaining shaft aperture 40. The aperture for the brake shaft 41 is made at an upward angle and is elongated, and is also made through both sides of this section.

Place all parts loosely onto their respective shafts, Fig 28 should be used as a guide.

When all are placed onto the arm connecting shaft, bend over the two split-ends I3 and I5, then the single split-end I4, the other split-.

end is broken off.

Place the middle torso section 44 in a secure position so that when the left-arm 46 is attached to the arm connecting shaft it will not be obstructed.

Place the arm connecting shaft 2 as shown in Fig 8 into the arm connecting shaft slots 42 and push the two smooth bore bushes 10 and 12 into position at the base of the slots.

The upper left-arm plug 6 has had a section removed from its top end.

The angle of the right-wall 9 is at 120 degrees minus the wideth of the single left-arm tongue '4 , the angle of the left-wall is at an angle of 2IO degrees. The depth of the section removed will deep enough no that. the single tongue 14 will not be able to reach the top of the wall when the upper left-arm plug is fitted into the upper left-arm plug aperture 51.

Take the left-arm 46 and push the upper left-arm plug 6 into the upper left-arm plug aperture 51,and let the arm fall frie, it will be seen that the frre-arm will rivet across the bottom edge of the middle torso section 44,Turn the arm connecting-shaft 2 until the left edge of the single left-arm tongue is at an angle of 120 degrees; then turn the upper left-arm plug until the right-wall 9 is tcuching the right edge of the tongue. Secure upper left-arm plug 6 into the upper left-arm aperture.

The right-hand 48 is shaped slightly cupped; although the fingers are straight and fully extended, a cavity is made in the ball of the hand into which is fixed a small round magnet 50, the right-arm 47 is turned so that the palm of the right-hand is facing to the rear, see Fig 2I.

In the inside of the upper right-arm 47 a cavity is made which i8 deep enough and wide enough for the two right-arm tongues I3 and 15 to be inserted and permanently fixed into, making sure that the forearm is still resting along the bottom edge of the middle torso section 44.

Insert the spring and cord retaining shaft 18 into one of the spring and cord retaining shaft apertures 4 and loop on the spring 20 and loop on the cord I9tnen push the shaft through the other aperture and secure shaft in position by fixing on circ-clips I6 and I7, then push the spring and cord down through the hollow section of the middle torso section 44.

Take up the cord winding shaft 3I and push it through the cord winding shaft aperture 25 on the left-side of the lower torso and leg section 43, and and put the cord winding shaft pulley-wheel 21 before pushing the shaft through the right-side aperture, put on smooth bore bushes 36 and 38 then fix onto the shaft circ-clip 37, push both smooth bore bushes into position, plt the stopping block 23 onto the shaft but do not secure.

Now secure onto the cord winding shaft the cord winding shaft turning knob 39, fix the cord 19 permanently onto the cord winding shaft pulleywheel, making sure that the cord has been past over the top and down to the rear of the arm connecting shaft pulley-wheel. See Fig 28.

Now fix the middle torso section 44 to the lower torso and leg section 43 temporarily.

By some means rotate the cord winding shaft pulley-wheel 21 so that the excess is wound onto the pulley, making sure that the spring and cord retaining shaft 18 is still in its position as shown in Fig 28 and that neither of the arms have started to rise, if all is correct, secure the cord winding shaft pulley-wheel to the shaft.

Insert the spring retaining shaft 26 through one of the spring retaining shaft apertures 40 and pass it through the loop of spring 20 then push it through the other aperture and then put on the;two BSpoth ber. bushes 28.--id., then secure in position by fixing on the two circ-clips 27and 30.

Take the brake shaft 32 and insert it through the brake shaft aperture 41 on the right-hand side of the lower torso and leg section 43, put the smooth bore bush 34 onto the shaft then the circ-clip 35 , push the smooth bore bush into the elongated aperture and push the brake shaft through the opposite aperture then fix circ-clip 33 onto the shaft.

At this stage, all components are now fixed securely onto their shafts except for the stopping block 23.

Now turn the cord winding shaft turning knob 39 in a clock-wise direction. It will be seen that the right-arm 47 will rise whilst the left arm will remain stationary.

When the fingers of the right-hand 46 are at an angle of 270 degrees, the left-arm 46 will begin to rise, both arms are now rising together.

When the left- forearm touches the face stop turning the knob but hold it in that position, it will now be seen that the right-arm has risen and is at an angle of 20 de degrees behind the head.

With your right-hand holding the right-leg to keep the Over-arm CricKet Bowler upright and standing firmly on the playing surface; and your finger and thumb of your left-hand holding the turning knob, use the next finger to pull down the brake shaft 32 to the bottom of the brake shaft aperture 41. Now gently turn the cord winding shaft turning knob 39 anti-clockwise and lower the arms; when the fingers of the right-hand are at an angle of 320 degrees, turn the stopping block 23 until its left edge is touching the brake shaft 32, holding the stopping block in this position; push the brake shaft 32 out of the way of the stopping block 23 and still turning the turning knob anticlockwise lower the arms. Now fix permanently in position.

The cricket ball to be used ( not illustrated ) is a one centimetre in diameter with a small metal disc fixed into the top and bottom of the ball. The ball is placed onto the magnet 50 before the arms are raised, when the right-hand 48 fingers are at an angle of 20 degrees pull the brake shaft 32 into position. Release the cord winding shaft turning knob 39. The tension of spring 20 will bring the bowling arm forward and down at speed, and the ball will be propelled forward and down towards the wickets and or batsperson.

This action will now become repetitive.
