reference will now be made to the drawings wherein like numerals preferred to like parts throughout . fig1 illustrates one embodiment of a supplemental feed block holder 100 . as illustrated on this embodiment , the supplemental feed block holder 100 is generally u - shape having a feed block post 102 that is adapted to receive a supplemental feed block 160 in a manner that will be described in greater detail below and a mounting post 104 that is adapted to be attached to a vertical post of a fence or corral . both the supplemental feed block post 102 and the mounting post 104 extend outwardly in the same direction from a first side 112 of a base member 110 that interconnects the supplemental feed block post 102 and the mounting post 104 . as illustrated in fig1 in this embodiment , the feed block post 102 is generally cylindrical in shape and has a first section 114 of a first diameter in a second section 116 of a second diameter that is less than the first diameter . the first section 114 is mounted on the upper face 112 of the face member 110 and the second section 116 is positioned on an outer face 120 of the first section 114 of the feed block post 102 . as is illustrated in fig1 the outer end 122 of the mounting post 104 is preferably capped with a cap 122 that has a generally rounded configuration so as to reduce the risk of injury to livestock who rub up against the feed block holder 100 . the supplemental feed block 100 is preferably adapted to allow for the mounting of particularly heavy supplemental feed blocks including salt blocks or blocks impregnated with supplemental minerals and nutrients that are to be consumed by livestock , such as horses and cattle . in one particular embodiment , the mounting post 104 is comprised of a 2 inch diameter aluminum tube with ½ inch thick walls that is approximately 6 inches in length and it is attached to the base member 110 which is comprised of a flat piece of aluminum which measures ⅜ of an inch thick by 2 and ½ inches wide by 8 inches long . the mounting post 104 is attached , preferably through well known welding techniques so as to be a ¼ of an inch from the end of the base member 110 and so as to be centered on the base member approximately ¼ of an inch from either side of the base member . the feed block support post 102 is also comprised of an aluminum tube or bar that is positioned ½ an inch from the end and centered on the base member 110 so as to be ½ of an inch from the sides of the base member . the first section 114 of the feed block post 102 is , in this embodiment , is 1½ inches in diameter and has a length of approximately 2 and ¼ inches . the second section 116 of the feed block post 102 has 1 inch in diameter and is 3 and ¼ inches long such that the feed block post 102 is approximately 5 and ½ inches long . the outer surface of the second section 116 of these feed block post 102 can be configured so as to be adapted to receive supplemental feed blocks having openings of different configurations . for example , in one embodiment , the feed block post 102 can have a tapered shape so as to better support feed block having conical shaped openings . it will be appreciated that the dimensions listed herein are simply exemplary dimensions of one particular embodiment of the invention and should not be taken as limitation on the overall size of the feed block hold as the feed block holder 100 can be adapted to support feed blocks of any of a number of different sizes and shapes without departing from the spirit of the present invention . referring now to fig2 the manner in which the feed block holder 100 is attached to a vertical post 130 of a fence 132 is illustrated . in particular , the use of the elongate mounting post 104 allows for the attachment of the feed block holder 100 at two different vertical locations through the use of securing devices 140 such as clamps or straps . in particular , as illustrated in fig2 the mounted post 104 is attached to the vertical post 130 at a bottom end 142 of the mounting post 104 with a first securing device 140 a which , in this embodiment , is comprised of a clamp that is adapted to fit about both the mounting post 104 and a circular pipe comprising the vertical post 130 such as the types of pipes that are commonly used in horse pipe corral structures . similarly , a second securing device 140 b is attached to the upper end 144 of the mounting post at approximately the same height above the base member 110 as the top of the feed block post 102 using a securing device 140 b such as a clamp . in this embodiment , the securing devices 140 a , 140 b are comprised of clamps that have a first member 150 a and a second member 150 b each of which define generally circular recesses that are adapted to receive the generally circular mounting post 104 and the generally circular fence post 130 . the clamp members 150 a , 150 b are interconnected with a nut and bolt assembly 152 that attaches the clamp members 150 a , 150 b together at the middle of the clamp members 150 a , 150 b , such that tightening of the nut and bolt assembly 152 squeezes the mounting post 104 and the fence post 130 between the recesses define by the clamp members 150 a , 150 b such that the mounting post 104 is secured to the vertical post 130 . these types of clamps are well known in the art and , it will be appreciated , that there are simply exemplary of one preferred type of device for securing the feed block holder 100 to the fence 132 and that any of a number of different securing devices can be used without departing from the spirit of the present invention . as is illustrated in fig3 a , a feed block 160 which , in this embodiment , is comprised of a salt block that is generally in a shape of a cube that is generally approximately 8 inches tall by 8 inches wide by 8 inches deep is mounted so as to be centered on the feed block mounting post 102 . the feed block mounting post 102 extends into the approximate middle of the block 160 such that the block 160 is securely positioned on the feed block post 102 . it will be appreciated that because the supplemental feed block 160 is relatively heavy , e . g . up to 50 pounds or more in weight , and is mounted so as to be cantilevered out from the fence post 130 by the base member 110 , the tendency of the supplemental feed block holder 100 under the force of the supplemental feed block 160 is to rotate about a pivot point which occurs at approximately the interconnection between the bottom end 142 of the mounting post 104 where the securing device 140 a attaches the feed block holder 100 to the fence post 130 . however , the use of an upper securing device 140 b that secures the top end 144 of the mounting post 104 to the fence post 130 effectively counter acts the tendency of the feed block holder 100 to pivot in response to the loading of the feed block holder 100 by the heavy supplemental feed block 160 . in this way , the supplemental feed block holder 100 is able to be more securely attached to the fence post 130 such that is will stay rigidly attached to the vertical post 130 over longer periods of time without straining or breaking the securing devices 140 a , 140 b . fig3 b further illustrates the manner in which a supplemental feed block 160 , such as a salt block is mounted on the feed block post 102 . in particular , most commonly sold salt blocks 160 have an aperture or cavity 162 that is generally tapered inward as illustrated in the cut way view of fig3 b . the second section 116 of the feed block post 102 is dimensioned so as to be able to extend to the apex 164 of the aperture 162 in the salt block 160 . the outer surface 120 of the larger diameter first section 114 of the feed block post 102 gouges into the inter walls 166 of the aperture or cavity 162 so as to secure the salt block 160 on the feed block post 102 . moreover , the tip 165 of the second section 116 engages with the apex 164 so as to further laterally stabilize the feed block 160 on the holder . hence , the outer perimeter of the first section 114 of the feed block post 102 and the tip 165 of the second section 116 has the effect of laterally stabilizing the salt block 160 on the feed block post 102 . it will be appreciated that significant forces will be exerted upon the feed block 160 when livestock are eating the outer surfaces of the feed block 160 . these significant forces can result in a feed block being dislodged from the feed block post 102 , however , the use of larger diameter outer surfaces on the first section 114 of the feed block post 102 inhibits the dislodgment of the feed block 160 from the feed block post 102 as a result of livestock eating the feed block . moreover , some feed blocks 160 have smaller diameter aperture 162 and the use of multiple sections on the feed block post 102 having different dimensions facilitates the mounting of feed blocks having different size apertures . as is also illustrated in fig3 b , the feed block post 102 extends into the center of the supplemental feed block 160 about the same distance that the second end 144 of the mounting post 104 extends outward from the base member 110 . by attaching the second end 144 of the mounting post 104 with a separate securing device 140 b , the tendency of the holder 100 to pivot as a result of the weight of the block 160 is reduced due to the center of mass of the block 160 being supported at substantially the same height that the second end 144 of the mounting post 104 is attached to the fence post 130 . from the foregoing , it will be appreciated that the feed block holder 100 of the preferred embodiment is more securely mounted to a fence post , more securely retains a supplemental feed block such as a salt block and is more flexible in being able accommodate supplemental feed blocks of different sizes and manufactures . moreover , as the feed block is essentially comprised of three components in this embodiment , the feed block post of the preferred embodiment is more inexpensively manufactured than the more complex feed block mounting structures of the prior art . consequently , an inexpensive , stable feed block holder is now available for livestock owners to mount supplemental feed blocks in a position where they are elevated from the ground and are thus less prone to contamination and damage as a result of being positioned on the ground . although the foregoing description of the preferred embodiment of the present invention has shown , described and pointed out the fundamental novel features of the invention , it will be understood that various omissions , substitutions , and changes on the form of the detail of the apparatus as illustrated as well as the uses thereof , may be made by those skilled in the art without departing from the spirit of the present invention . consequently , the scope of the present invention should not be limited to the foregoing discussions , but should be defined by the appended claims .
a feed block holder having a generally u - shape configuration with a first mounting post adapted to be secured to a vertical fence post at a least two locations along the length of the mounting post , and a feed block support post that is adapted to receive a supplemental feed block with a base member interconnecting the mounting post and the feed block support post . the mounting post and the feed block support post preferably extend in the same direction such that the plurality of securing points on the mounting post counteracts the tendency of the holder to pivot in response to loading of a supplemental feed block such as a salt block on the feed block holder . the feed block support post is configured to have a inner larger diameter section and a outer smaller diameter section such that lateral stability of the feed block can be provided as a result of the engagement of the larger diameter section of the support post engaging with the inner walls of a cavity formed in the supplemental feed block .
