Abstract:
The golf green speed and contour teaching device is used to help the golfer learn and understand the green he is about to putt on. Golfers usually take years of practice to become proficient at learning the speed and route the ball will take when struck. He must putt over and over, and over again to familiarize himself with the terrain and the grass to be able to make the correct putt on the ball. The grass heighth, dampness and other factors are not easily understood by the novice, and can make him putt a poor shot. Also, ridges or valleys in the green make contour reading difficult. Many professionals have difficulty even after years of practice. This instrument will speed up the golfer&#39;s learning process and even the amateur can become proficient at putting. This instrument will give him wisdom.

BACKGROUND  
         [0001]    In the game of golf, it has long been known and acknowledged that putting the ball on the green is a very integral part of the game. The putting makes up about half of the scoring in the game. Errors, or poor putting, is very damaging to the golfer&#39;s score. Many efforts have been made to help learn the skill of putting and most of these efforts have been directed to the golfer&#39;s swing, follow through, and gentle touch put on the putter when putting the ball across the green. There have been numerous aids or devices developed for the golfer to learn how to putt successfully. Putting pads (simulating greens), mirrors, laser beams, restricting boxes, arm straps, and numerous other innovations have been tried and have met with some success (action on the putter). The experienced golfer has difficulty at times reading these routes exactly. The experienced and professional golfers take years to learn the geographic and mathematical knowledge for this skill.  
           [0002]    Teaching devices helped the golfer learn the putting stroke. However, if the golfer can stroke the ball perfectly he must also be able to determine the speed the ball needs to move and the route it takes to reach the hole. This must be read as a straight line and the contour of the land it must travel taken into account and evaluated. This takes skill and knowledge combined. This means he must read the undulations, slopes, downhill and uphill contours the ball will travel to reach the hole. If this is not determined correctly or “read” properly there is a good probability that the shot will be missed even though the golfer had the perfect swing pattern. As mentioned above the speed of the ball is also very important. The ball must have the momentum to get to the hole and yet if it has too much momentum or speed it may pass far beyond the hole even if the path is correct. It may pass over the hole and beyond the hole a long distance requiring another contour evaluation and another shot.  
           [0003]    The speed of the green is determined by a variety and a surprisingly number of factors. The heighth of the grass, dampness, grass type, cutting of the grass, amount of wear, wind, etc all affect the speed of the green. The official speed of the green has been determined and given a number grade by using a Stimpmeter. This instrument was developed by Mr. Stimp in 1937 in England. It is still used today and considered the “standard” method.  
           [0004]    These Stimpmeters are used by the large golf courses and their greens graded. They are expensive and smaller golf courses do not have these determinations. They are large and cumbersome and the general public does not have access to these unless they purchase the stimpmeter personally. It is for these reasons I have developed the following device for the average golfer. I feel it would be beneficial to help the golfer learn to read the greens. It is to be used only as a learning device and not used in a game.  
         SUMMARY  
         [0005]    The putting portion of the game of golf accounts for half or more of the score. The winner of the golf game is the golfer with the lowest score. Since putting is so important and makes up such a large portion of the final score, the golfer must be a good at putting the ball in order to compete. No efforts have been made to give the putter methods to improve his ability to read the greens.  
           [0006]    This new invention is presented and will be a good teaching way to speed up his learning process for reading the greens speed and contour. A tubular device that has a spring loaded plunger or piston to propell the ball out of the opposite end of the tube in a straight line. The plunger or piston has different stops where the tension of the spring is changed to allow different speeds and distances the ball will travel. Between 5 and 10 stops have been suggested for different distances and the first 2-3 stops can be used as a stimpmeter which will help determine the speed of each green.  
           [0007]    The distance the ball travels is in a straight line and is always the same distance which is usually more accurate than the golfer&#39;s putt.  
           [0008]    Since it will always travel in the same direction, and the same speed, it can be used to check where the ball should move to gauge the contour and the speed to the hole. This will help the golfer to decide where to shoot the the ball. If wrong in his evaluation then he can rethink the shot and then try again. If this is not correct, again his knowledge will improve, and he can study the shot and learn by his mistakes. The device will help him learn both the speed the ball should travel and the route it should take with the contours of the green noted.  
           [0009]    The device has a laser beam mounted on the front and top to help with the determination of the area to shoot the ball for the contour and speed. The device can store or carry one or more golf balls which will drop into place for shooting to the designated spot. The device is small enough to fit into the golf bag for carrying it easily to other courses and greens. The propelling plunger or pusher could also be motorized and a small motor used to actuate the plunger. The motor could be battery operated or electrically operated if desired. The trigger for the plunger could also be electrical (AC or DC) and the different positions for the plunger movement and placing the ball into the chamber for discharge can all be electrically connected. The simple method of using springs is felt to be a much easier and less complicated. The main action of a plunger propelling the ball out the end of the chamber like a bullet from the end of the gun is the basic idea for the invention.  
           [0010]    In preparation, evaluation and studying the exact putting shot that is to be made, the golfer is only human and may make a mistake in putting the ball and it may travel in the wrong direction or be the wrong speed. He then does not know if his read of the green was correct and he struck the ball improperly or he did not read the green correctly. With this device it takes out the possibility of hitting the ball wrongly and just tells him if his read was accurate and correct. He can then determine where he made the mistake and correct it, learning from the mistake. This will help him in the game when faced with the same or similar shot. Using the device on several greens and at different positions will give the golfer a very good knowledge of where and how hard to strike the ball. This should greatly improve his game score.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0027]    The device presented here is simply a cylinder holding a golf ball to allow a spring activated plunger to strike the ball. This propells the ball out the end of the chamber, similiar to a bullet out the end of a barrel of a gun. A prototype is seen in FIG. 1 which demonstrates howe the ball is thrust out the end by the plunger or driver represented by  1 G. There is also a laser light  1 A that is attached to the top of the device or handle at  1 B. This will help determine if his evaluation of the surface and the distance was correct.  
         [0028]    The distance the ball will travel is determined by the power lever,  1 C, and different speeds are made by compressing the drive power spring to different compressions. The spring is represented by  1 K. It is compressed against a buttress,  1 M, which is stationary and stable. The stronger the compression, the longer distance the ball will travel. The graduated slots on the body will give accurate distance determinations. The plunger is controlled by the power lever,  1 C, which the golfer places into the desired slot position,  1 N.  
         [0029]    The ball falls into the discharge cylinder,  1 P, and goes to a designated position there. This is done by a base triangular block,  1 N, which will not allow the ball to move back any further in the cylinder than the block will allow. The forward motion is limited by a restrictive rod,  1 J, which is mobile and can be moved out of the position whenever the trigger to release the plunger is activated. This then releaves the forward motion obstacle and allows free unimpedded ball rolling to occur.  
         [0030]    The trigger designated as  1 H is attached to a cylinder  1 D which rotates inside the outside or main cylinder. This inside cylinder when moved by the trigger, rotates clockwise and it&#39;s edges move the power lever out of the designated slot on the main cylinder and into the free area just above the slots. This allows the plunger to thrust forward and strike the ball. At the same time the cylinder rotates to move the power lever out of it&#39;s slot, it also turns the arm that controls the restrictive rod,  1 J, and this turning moves the rod out of the exit area of the discharge chamber allowing the ball,  1 O, to exit unimpeded.  
         [0031]    The reserve chamber,  1 R, holds the balls until ready for usage. The extra balls are placed in the top, pass through a spring lock pin  1 L and into the storage area. The spring acts as an open safety pin would by allowing compression and entrance but will not open up any more to allow the balls to come back out. This is useful when the device is layed onto it&#39;s side or turned over. The lower end of the reserve chamber has a reserve restriction pin or rod. This is an inflexible rod,  1 I, that stays in a protruded of locked position until it is manually released. When this occurs a spring located just outside the chamber is attached to the neck of the ring and the chamber wall. When it is expanded to release the ball by pulling the rod back out of the reserve area, the spring quickly returns the rod to it&#39;s “in canal” and resting position.  
         [0032]    At the rear end of the device and located inside the trigger cylinder is a spring represented by  1 Q and it returns the trigger cylinder to it&#39;s original and resting position. When this occurs the rod  1 J at the other end is restricting the forward golf ball movement is in the position of locking the exit and preventing ball movement forward. The trigger cylinder does this at the position  1 K where it acts on the one piece rod moving here which thereby moves the other end of the rod out of the canal.  
         [0033]    In FIG. 8 the ball reserve mechanism is noted. There is the pull ring,  8 B, attached to the rod  8 D in which a portion of the rod passes into the reserve chamber  8 A preventing the ball  8 E from falling into the discharge chamber. Also, is noted the restrictive spring  8 C which holds the bolt or rod in the chamber at all times except when it is manually pulled out of the area.  
         [0034]    The FIG. 9 shows an expanded spring at  9 C allowing the rod  9 D to be pulled completely out of the chamber  9 A and thereby allowing the ball  9 E to fall in the discharge chamber. The pull ring will then be released and the rod go back into the chamber to restrict the next ball from dropping down any further.  
         [0035]    In FIG. 10 the trigger  10 A is seen attached to the body of the reserve chamber  10 D and also attached to  10 C the inside cylinder which controls the action on the power lever and the rod restrictor in the discharge chamber. The trigger  10 A has a hinge in it&#39;s middle to allow for easy upward pull and release any tightness of tension with the movement on the cylinder below it.  
         [0036]    [0036]FIG. 11F is a view of the front of the reserve chamber and the discharge chamber  11 C. Slso the back trigger cylinder  11 D is seen with the control attachment  11 E seen as a bolt attachment. There is an open slot  11 B in the outer discharge cylinder  11 C to allow for the action and movement of the trigger cylinder. There are also the attachments of the trigger  11 A which are  11 H screw fixation to the chamber and  11 G screw connection of the two arms making up the trigger. Here the upward motion of manually pulling up the trigger will cause the inner cylinder to upward and with it&#39;s connections to the power lever and the ball restrictor rod release these to allow the plunger to strike the ball and thrust it out the end of the cylinder.  
         [0037]    [0037]FIG. 12B is a cross-section of the main cylinder of the device with an opening at  12 A for the power leve and noted is  12 C which is a disc like restriction solidly attached to the wall for a buttress for the main power spring and to support the central drive shaft for the driving plunger.  
         [0038]    [0038]FIG. 13A illustrates the upright lever which is attached  13 B to the drive shaft represented as  13 D. The main power spring  13 C is attached to the power head at  13 E. As is demonstrated the spring when compressed by  13 A will, when released, cause the plunger to move outwardly. How fast the plunger moves out is dependent upon the compression of the spring. The driver head  13 E must stay in the discharge chamber while it is further stabilized by the buttress opening the shaft of the driver passes through. This helps for the driver and shaft to be well aligned when the action is initiated. This is seen well in FIG. 14 where the components are all aligned and the connections demonstrated. The Head driver  14 E is connected to  14 F which is connected to the control lever  14 A. The central buttress  14 C helps stabilize the shaft  14 F and provide the base for the spring  14 D to work against. The spring  14 D is attached to the head  14 E further preventing the head from going any further forward but this is also controlled by the buttress and control lever in the rear.  
         [0039]    In FIG. 15 the compressed and loaded position is demonstrated. This shows how  15 A, the power lever, has pulled the plunger back to the back ower position  15 D and the shaft  15 F has slid through the buttress disc  15 E and this compressed  15 G the spring pulling  15 H into the position for striking the ball. The release of this will occur when the trigger is pulled upward on the trigger cylinder which pushes the power lever out of it&#39;s slot position, releasing the compressed spring.  
         [0040]    [0040]FIG. 16 shows the slot positions  16 B and the other positions of the body cylinder that have been cut out for different actions to occur. The slot  16 D allows for the trigger action and slots  16 C and  16 E are for the ball restrictive rod on the right side of the instrument. These slots allow for the inside cylinder to move the action connections and make the necessary releases to occur.  
         [0041]    [0041]FIG. 18 shows the outer cylinder with the cut outs made as  18 B and  18 C. This cross-section of  18 A the large cylinder is to show how the inner trigger cylinder in FIG. 19C which has a screw and a bolt that will work outside components can complete the motions.  
         [0042]    [0042]FIG. 20 is used to demonstrate just how the ball restrictor rod occurs. It shows how the inside cylinder stays in one position at all times using the inside spring shown as  20 H. This spring is attached to the inside cylinder which is movable, and to the outside unmovable cylinder to hold the movable cylinder in a constant resting position. When the cylinder is manually moved it will readily return to the original position by the spring action. The spring can be either a compressed spring or an expanded spring. Also demonstrated in FIG. 20 is the rod action restricting the ball&#39;s exit from the discharge chamber. The inner cylinder  20 B moves the one piece rod which is encased in a cylinder  20 D on the outside cylinder and is firmly attached to it and allows the rod to rotate accurately and smoothly whenever action occurs. The rear end  20 E is protruding into a small hole  20 G in the cylinder  20 B. When the trigger cylinder moves, it moves the rod end and this in turn turns the whole rod which turns the end restriction rod. As the rod is moved more, the restrictive rod is moved and eventually moves out of the canal blocking the ball&#39;s exit. The is demonstrated in the FIG. 21 which shows the location of the restrictive rod  21 E steadily held by  21 D and connected to  21 C the restrictive rod. Opening  21 F is for the exit and entrance of the restictive rod and  21 G is for the cylinder action to cause the movement of the rod. Again shown in the  21 H is the spring to the trigger cylinder to maintain it&#39;s closed position.  
         [0043]    The drawings try to demonstrate all the actions put forth for this invention. Other materials such as aluminum or different plastics which could also be used. Even a small motor using batteries or electricity could be used in this device. The device can, and was, made without the reserve ball shute or chamber. It is less weight but was not a convienent. You ususally had to carry the extra balls and this was inconvenient. The laser-beam can also be excluded, but the device was not felt to be as accurate without it.
