METHOD AND TAPE CONSTRUCTION FOR LAYING OUT A
BASEBALL DIAMOND
BACKGROUND OF THE INVENTION
This invention relates to a method for layin~ out a 5 baseball diamond and to a reel of tape arranged for use in layin~ out a baseball diamond.
The baseball diamond has, as you well know, three bases, home plate and a pitcher's mound. The bases are spaced by a pre-determined distance which can varV dependin~ upon the variety 1Q of the game being played. It is of course highly desirable that the angles of the diamond be accurate so that the diamond is properly "squaren , Many baseball diamonds are permanently laid out and marked. In other situations, generally in recreational baseball, it is 15 necessary to mark out the diamond on a bare ground before the ~ame is commenced. In the latter case particularly but also generally, it is desirable that the locations for the bases relative to home plate be positioned accurately and quickly.
It's one object of the present invention, therefore, to 20 provide an improved method for laying out the base markers for a baseball diamond. -It's the second object of this invention to provide an improved tape reel which can be used in laying out a baseball diamond.

One embodiment of the invention will now be described in conjunction with the accompanying drawings in which:
BRIEF DESCRIPTION OF THE DRAWINGS
4 212~
Figure 1 is a schematic isometric view of a reel and tape accordin~ to the present invention.
Figures 1 A, 1 B, 1 C and 1 D show the details of the indicia on the tape of figure 1.
Figure 2A, 2B, 2C, 2D, 2E and 2F show a series of steps for use of the tape of Figure 1 in the method of layin~q out a baseball diamond .
In the drawin~s like characters of reference indicate corresponding parts in the different figures.
DETAILED DESCRIPTION
The tape and reel as shown in Figure 1 are basically conventional in that the reel comprises a reel body 10 with a handle 11 by which the reel can be lifted and moved from place to place. At the lower end of the reel body is provided a pointed lower member 12 which can be placed on the ~round at a required location. The reel body carries a shaft 13 to which an inner end 14 of the tape 15 is attached. An outer end 16 of the tape is attached back to the reel body for example at the pointed member 12 to form a loop of the tape of a predetermined length. The tape can thus be reeled onto the body to be carried with the ree! or can be pulled out in a loop as shown in Figure 1.
In addition to the conventional reel and tape there is provided a slide member 17 with a manually ~raspable portion 18 and a roller 19 which allows the slide member to slide along the tape to 212~
assist in pulling the loop from the reel and manually manipulatin~ the loop without sliding the loop against the fin~ers of the user.
The tape is modified by the provision of four markin~s includiny a first marking 20, a second markiny 21, a third markin~ 22 5 and a fourth markin~ 23. The first markin~ as shown in the drawin~
is indicative of first base and includes a specific location mark on the tape to~ether with the words "FIRST BASEn~ The second markin~ 21 and the third markin~ 22 are similar to the first markings except that they designate or indicate "SECOND BASE" and "THIRD BASEn 10 respectively. The fourth markin~ 23 is a~ain similar but includes the words "PITCHER'S PLATE".
The markin~s are located on the tape such that the first markin~ is spaced from the outer end of the tape by distance x, the second base marking is spaced from the first base markin~ by a 15 distance x that is by a distance 2x from the outer end. The third base markin~ is spaced from the inner end by a distance x. The full length of the loop is equal to 2x + ~12x. Thus the distance between the second base markin~ and the third base markin~ is equal to ~2x-x.
The pitcher's plate markin~q is spaced from the inner end by a 20 distance y. The distance x is equal to the required spacing between the bases. The distance y is equal to the required distance of the pitcher's mound from home plate. These distances are specified in the particular variety of ~ame concerned and-these~distances vary from 60 feet in some cases up to 90 feet in other cases.
212~
Turning now to Fi~ure 2, the steps of use of the tape and reel of Figure 1 are shown schematically. In the first step a pe~
is placed in the yround at a selected location for home plate on an unmarked fieid or a field in which the diamond is to be marked. The ;
5 point of the reel is located at the pe~ to start the layout. The reel is held at this position permanently until the layout is complete. ;
In step 2 the pulley 17 is yrasped and four further pegs are carried with the operator while the operator walks toward the desired location of first base. As the tape is pulled out, the operator 10 watches for ~he first rnarking and on reaching the first marking grasps the tape at the point, pulls the tape taut and strai~ht and locates the peg at the required position. This position can be moved in an arc around home plate until it is best located for the orientation of the diamond on the field. The tape is then wrapped around the 15 upstandin~ pe~.
In step 3 the operator ~rasps a3ain the pulley 17 and walks away from the peg pulling the tape around the pe~ while walking in the general direction of second base. The operator watches again for the second marking and on reaching the second 20 marking yrasps the tape at that point and then pulls the tape into a taut triangle with the apexes of the triangle arranged at home plate, at the peg at first base, and at the second markin~q. With the tape taut and the trian~le having strai~ht sides, the position of second base is thus located and the second pe~ is applied at this position.
~^ 7 The pe~ for second base is positioned inside the loop so as to hold the tape taut in the first trian~le.
In step 4 the operator leaves the tape in the first trian~le and walks along the tape toward home plate to locate the fourth 5 markin~. A peQ is then applied into the ~round at the fourth markin~
to identify the position of the pitcher's plate. The fourth marking is located at the required spacing from home plate that is at the distance y from the inner end of the tape.
In step 5, the tape loop is removed from the second pe~
10 and the operator walks in the ~eneral direction of third base while pullin~ the tape loop by ~raspin~ the pulley 17. At the same time the operator looks for the third markin~ and on reaching this marking 3rasps the tape at that point and pulls it so that it forms a second trian~le with the apexes at home plate, at the peg at first base and at 15 the third markiny. The fourth peg is then applied to the ~round at the third base markin~ with the triangle held taut.
The tape is then removed from the pegs and rewound onto the reel. The pegs thus indicate the positions of the bases and the pe~s can be removed and the necessary bases placed in position 20 at exactly the required location.
Since various modifications can be made in my invention as herein above described, and many apparently widely different emboàiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all ,''.; ~."~ ' .

Figure 1 is a schematic isometric view of a reel and tape accordin~ to the present invention.
Figures 1 A, 1 B, 1 C and 1 D show the details of the indicia on the tape of figure 1.
Figure 2A, 2B, 2C, 2D, 2E and 2F show a series of steps for use of the tape of Figure 1 in the method of layin~q out a baseball diamond .
In the drawin~s like characters of reference indicate corresponding parts in the different figures.
DETAILED DESCRIPTION
The tape and reel as shown in Figure 1 are basically conventional in that the reel comprises a reel body 10 with a handle 11 by which the reel can be lifted and moved from place to place. At the lower end of the reel body is provided a pointed lower member 12 which can be placed on the ~round at a required location. The reel body carries a shaft 13 to which an inner end 14 of the tape 15 is attached. An outer end 16 of the tape is attached back to the reel body for example at the pointed member 12 to form a loop of the tape of a predetermined length. The tape can thus be reeled onto the body to be carried with the ree! or can be pulled out in a loop as shown in Figure 1.
In addition to the conventional reel and tape there is provided a slide member 17 with a manually ~raspable portion 18 and a roller 19 which allows the slide member to slide along the tape to 212~
assist in pulling the loop from the reel and manually manipulatin~ the loop without sliding the loop against the fin~ers of the user.
The tape is modified by the provision of four markin~s includiny a first marking 20, a second markiny 21, a third markin~ 22 5 and a fourth markin~ 23. The first markin~ as shown in the drawin~
is indicative of first base and includes a specific location mark on the tape to~ether with the words "FIRST BASEn~ The second markin~ 21 and the third markin~ 22 are similar to the first markings except that they designate or indicate "SECOND BASE" and "THIRD BASEn 10 respectively. The fourth markin~ 23 is a~ain similar but includes the words "PITCHER'S PLATE".
The markin~s are located on the tape such that the first markin~ is spaced from the outer end of the tape by distance x, the second base marking is spaced from the first base markin~ by a 15 distance x that is by a distance 2x from the outer end. The third base markin~ is spaced from the inner end by a distance x. The full length of the loop is equal to 2x + ~12x. Thus the distance between the second base markin~ and the third base markin~ is equal to ~2x-x.
The pitcher's plate markin~q is spaced from the inner end by a 20 distance y. The distance x is equal to the required spacing between the bases. The distance y is equal to the required distance of the pitcher's mound from home plate. These distances are specified in the particular variety of ~ame concerned and-these~distances vary from 60 feet in some cases up to 90 feet in other cases.

Turning now to Fi~ure 2, the steps of use of the tape and reel of Figure 1 are shown schematically. In the first step a pe~
is placed in the yround at a selected location for home plate on an unmarked fieid or a field in which the diamond is to be marked. The ;
5 point of the reel is located at the pe~ to start the layout. The reel is held at this position permanently until the layout is complete. ;
In step 2 the pulley 17 is yrasped and four further pegs are carried with the operator while the operator walks toward the desired location of first base. As the tape is pulled out, the operator 10 watches for ~he first rnarking and on reaching the first marking grasps the tape at the point, pulls the tape taut and strai~ht and locates the peg at the required position. This position can be moved in an arc around home plate until it is best located for the orientation of the diamond on the field. The tape is then wrapped around the 15 upstandin~ pe~.
In step 3 the operator ~rasps a3ain the pulley 17 and walks away from the peg pulling the tape around the pe~ while walking in the general direction of second base. The operator watches again for the second marking and on reaching the second 20 marking yrasps the tape at that point and then pulls the tape into a taut triangle with the apexes of the triangle arranged at home plate, at the peg at first base, and at the second markin~q. With the tape taut and the trian~le having strai~ht sides, the position of second base is thus located and the second pe~ is applied at this position.
~^ 7 The pe~ for second base is positioned inside the loop so as to hold the tape taut in the first trian~le.
In step 4 the operator leaves the tape in the first trian~le and walks along the tape toward home plate to locate the fourth 5 markin~. A peQ is then applied into the ~round at the fourth markin~
to identify the position of the pitcher's plate. The fourth marking is located at the required spacing from home plate that is at the distance y from the inner end of the tape.
In step 5, the tape loop is removed from the second pe~
10 and the operator walks in the ~eneral direction of third base while pullin~ the tape loop by ~raspin~ the pulley 17. At the same time the operator looks for the third markin~ and on reaching this marking 3rasps the tape at that point and pulls it so that it forms a second trian~le with the apexes at home plate, at the peg at first base and at 15 the third markiny. The fourth peg is then applied to the ~round at the third base markin~ with the triangle held taut.
The tape is then removed from the pegs and rewound onto the reel. The pegs thus indicate the positions of the bases and the pe~s can be removed and the necessary bases placed in position 20 at exactly the required location.
