There are, of course, additional features of the rail glide or grind bar that will be described hereinafter and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the rail glide or grind bar in detail, it is to be understood that the rail glide or grind bar is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The rail glide or grind bar is capable of other embodiments and being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of descriptions and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present rail glide or grind bar. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
It is therefore an object of the present invention to provide a rail glide or grind bar which has all of the advantages of the prior art and none of the disadvantages.
It is another object of the present invention to provide a rail glide or grind bar which may be easily and efficiently manufactured and marketed.
It is another object of the present invention to provide a rail glide or grind bar which is of durable and reliable construction.
