with reference now to the drawings and more particularly to fig1 a portable golf ball warming device 20 is illustrated and described . golf ball warming device 20 is configured and arranged for attachment to a carrying member such as golf bag 22 . golf ball warming device 20 is preferably disposed in a longitudinal direction with respect to golf bag 22 and may be permanently or removably affixed thereto . as illustrated , golf ball warming device 20 is affixed to golf bag 22 by a plurality of fastener tabs 24 . fastener tabs 24 are preferably hook and loop type fasteners such as those sold under the trademark velcro . as illustrated by the direction arrows of fig1 golf balls are inserted into the bottom of warming device 20 and removed from the top thereof . preferably , warming device 20 is attached to golf bag 22 or a golf cart ( not shown ) at an appropriate angle of approximately 45 to 60 degrees from vertical to allow for maximum exposure to available solar energy from a wide angle of incidence , such as would naturally occur when golf bag 22 is rested on a pull type golf cart ( not shown ). turning now to fig2 an exploded perspective view of golf ball warming device 20 is illustrated and described . warming device 20 includes base 30 which is preferably made from polycarbonate plastic and is opaque in color . base 30 supports parabolic trough reflector 32 , collector tube 34 , and transparent cover 36 . base 30 also provides support for a number of golf ball containment members including top aperture 38 and bottom aperture 40 through which the golf balls pass . top end cap 42 is slidably received within base 30 and forms an airtight barrier therewith . top end cap 42 is urged into a closed position with respect to base 30 by way of resilient compression members 44 . base 30 includes a pair of guide holes 46 which are recessed from the top side thereof . guide holes 46 are preferably cylindrical , however any tubular shape will suffice . guide holes 46 each include an enlarged portion which is configured and arranged to received a corresponding compression member 44 from top end cap 42 . compression members 44 are respectively connected to a corresponding guide rod 48 which extends downwardly from top end cap 42 . compression members 44 urge top end cap 42 into a closed position to seal collector tube 34 from ambient air . transparent cover 36 is preferably made from polycarbonate plastic or acrylic . cover 36 is permanently bonded to base 30 to thereby form a roughly open tubular container and collectively define a main body . base 30 supports top dispensing aperture 38 and bottom dispensing aperture 40 which are preferably made from an elastomer material which stretches under pressure . collector tube 34 is also supported by base 30 and is preferably a hollow , cylindrical , aluminum tube . collector tube 34 preferably has a light absorbing color such as black . parabolic trough reflector 32 is preferably a convex mirror shield made from a reflective material such as polished metal , or a reflective plastic film . the orientation of reflector 32 reflects solar radiation toward collector tube 34 and also redirects radiant heat emanating from collector tube 34 back toward collector tube 34 . reflector 32 is preferably described by a line approximately 4 . 5 to 5 . 5 inches in radius . turning now to fig4 a and 4b , reflector 32 is preferably capable of forming the above shape when forced into the allotted space between contact points 54 and 56 . contact points 54 and 56 are also bonding points for base 30 and cover 36 . this preferred method of friction fitting eliminates the requirement for any mechanical means of adhering base 30 to reflector 32 and also reduces the need for costly pre - forming of parts . thus , reflector 32 may be cut to size from available material in the marketplace . together , base 30 , reflector 32 , top dispensing aperture 38 , bottom dispensing aperture 40 , collector tube 34 and transparent cover 36 are bonded with an adhesive to thereby define a hermetically sealed and hollow structure . an unobstructed pathway is formed along an internal longitudinal axis of collector tube 34 to receive a plurality of standard sized golf balls . as illustrated in fig3 a , top end cap 42 includes an insulation section 50 which is compressibly received within the top end of collector tube 34 to form an air tight barrier . as illustrated in fig3 a , insulation barrier 52 ( optional ) may be disposed within a space between base 30 and reflector 32 . according to another embodiment of the present invention , insulation barrier 52 extends lengthwise within a space between base 30 and reflector 32 to retain heated air within warming device 20 . the space between collector tube 34 and transparent cover 36 is preferably filled with air . the air is preferably sealed within warming device 20 and separate from the air within collector tube 34 . thus , the air between collector tube 34 and cover 36 retains the heat output from collector tube 34 during use . fig3 a , 3b and 3c illustrate operation of the preferred embodiment of the present invention . fig3 a illustrates a configuration of the invention in which four golf balls are being warmed by solar radiation . in fig3 b - 3c , golf ball 5 is inserted into the bottom of warming device 20 and golf ball 1 is ejected therefrom . as golf ball 5 is inserted into collector tube 34 , the spring loaded top end cap 42 is urged upwardly against the force of compression members 44 . after golf ball 1 is removed from warming device 20 , compression members 44 urge top end cap 42 into the closed position . top dispensing aperture 38 and bottom dispensing aperture 40 are preferably made from an elastomer compound such as inner tube rubber . the material may be either pre - formed or cut from sheet shock . the apertures take on the appearance of common rubber and have a material thickness suitable for repetitive use . the apertures are respectively bonded to the upper and lower sides of base 30 by a suitable adhesive . the apertures are each formed with a centered circular hole having a diameter which is less than a standard sized golf ball . the diameter resists the passage of a golf ball such that the elastomer material is stretched evenly around the golf ball without tearing or deforming . the actual diameter of the hole size will vary depending upon material thickness and constitution . during operation of the preferred embodiment of the present invention , golf balls may be serially loaded into golf ball warming device 20 without allowing the passage of cooler ambient air . as illustrated particularly in fig3 c , the golf balls exert enough downward force on the bottom ball to create an air tight seal with bottom dispensing aperture 40 . through this arrangement , the lowermost golf ball cooperates with the golf ball warming device to eliminate the costly need for a further apparatus at the loading end to retain warm air within the device . as an additional feature , this arrangement facilitates manual operation of the device with a single hand , thus freeing the golfer &# 39 ; s other hand for other tasks . through experimental testing of an embodiment of the present invention , golf balls have been warmed significantly above 150 ° fahrenheit . in fact , according to a preferred embodiment of the present invention , golf balls are warmed to a temperature exceeding 180 ° fahrenheit . according to a second embodiment ( not shown ), the invention includes multiple collector tubes , convex reflectors , and an appropriate association of attaching components , so as to provide for a solar golf ball warmer of larger proportion and golf ball capacity for use on occasion where mobility is not of primary concern , such as on a golf course practice tee or for demonstration purposes . collectively , such an embodiment would not substantially deviate from the basic configuration of components described herein , and their interactive relationship with respect to the efficient collection , reflection , absorption , and conservation of solar energy for the purpose of warming golf balls . such an embodiment also allows for economic and efficient serial movement of golf balls through the device . turning now to fig4 a and 4b , sectional views taken along respective lines of fig3 a are illustrated . fig4 a illustrates a cross section through a modern two - piece golf ball 60 . golf ball 60 includes a solid inner core 64 which is preferably made from an elastomeric material . golf ball 60 also has a cover material 62 made from a rubber material such as surlyn . fig4 b illustrates golf ball 66 which is a lowermost ball within golf ball warming device 20 . fig5 - 8 illustrate a third embodiment of the present invention . as illustrated in fig5 - 8 , golf ball warming device 70 is similar to the preferred embodiment of fig1 . golf ball warming device 70 includes a base 72 , parabolic reflector 74 , collector tube 76 , transparent cover 78 and bottom dispensing aperture 80 . golf ball warming device 70 is preferably affixed to a golf bag or a golf cart by way of fastener tabs 82 . however , according to this embodiment , the top of warming device 70 is secured with top end cap 84 . top end cap 84 is more particularly illustrated in fig8 and is preferably in the form of a plastic hollow cup . top end cap 84 is configured to be received within the top end of collector tube 76 . top end cap 84 includes a felt band 86 which encircles an outer periphery thereof . felt band 86 forms an air tight barrier with the interior perimeter of collector tube 76 to retain warm air therein . felt band 86 may be made from another suitable material which has a low coefficient of friction and retards the passage of air . top end cap 84 includes insulation ( not shown ) which helps to maintain the warm air within the device . the foregoing is considered as illustrative only of the principles of the invention , and since numerous modifications and changes will readily occur to those skilled in the art , it is not desired to limit the invention to the exact construction and operation shown and described , and accordingly , all suitable modifications and equivalents may be resorted to , falling within the scope of the following claims .
