Other objects, features and advantages will occur to those skilled in the art from the following description of a preferred embodiment and the accompanying drawings, in which:
Aside from the preferred embodiment or embodiments disclosed below, this invention is capable of other embodiments and of being practiced or being carried out in various ways. Thus, it is to be understood that the invention is not limited in its application to the details of construction and the arrangements of components set fourth in the following description or illustrated in the drawings. If only one embodiment is described herein, the claims hereof are not to be limited to that embodiment. Moreover, the claims hereof are not to be read restrictively unless there is clear and convincing evidence manifesting a certain exclusion, restriction, or disclaimer.
The applicant's prior saw blade 30 is shown in
Blade 40,
In the preferred embodiment, first side 46 and second side 48 of arbor hole 42 are closely adjacent each other as shown, separated only by short side 54, and thus sides 46 and 48 conform to adjacent sides 50 and 52 of arbor 44, respectively. Short side 54 of arbor mounting hole 42 joins adjacent first and second sides 46 and 48. Third side 56 is connected to first side 46 and fourth side 58 connects third side 56 to second side 48.
Unlike prior arbor hole 14,
Thus, arbor hole 42 is significantly different than prior arbor holes and yet also operable with a traditional three-sided arbor, a modified three-sided arbor, and arbors of other configurations providing users with another source of replacement blades.
In the preferred embodiment, all sides 46, 48, 54, 56, and 58 are straight and connected together by non-radiused corners as shown in
In one example, the center of blade 40 was at location C, first side 46 was 1.601″ long, second side 48 was 1.537″, third side 56 was 1.601″, fourth side 58 was 0.899″, and short side 54 was 0.280″.
In other embodiments, however, these exemplary dimensions may change, short side 54 and/or fourth side 58 may be configured differently than as shown in
Thus, although specific features of the invention are shown in some drawings and not in others, this is for convenience only as each feature may be combined with any or all of the other features in accordance with the invention. Also, the words “including”, “comprising”, “having”, and “with” as used herein are to be interpreted broadly and comprehensively and are not limited to any physical interconnection. Moreover, any embodiments disclosed in the subject application are not to be taken as the only possible embodiments. Other embodiments will occur to those skilled in the art and are within the following claims.
In addition, any amendment presented during the prosecution of the patent application for this patent is not a disclaimer of any claim element presented in the application as filed: those skilled in the art cannot reasonably be expected to draft a claim that would literally encompass all possible equivalents, many equivalents will be unforeseeable at the time of the amendment and are beyond a fair interpretation of what is to be surrendered (if anything), the rationale underlying the amendment may bear no more than a tangential relation to many equivalents, and/or there are many other reasons the applicant can not be expected to describe certain insubstantial substitutes for any claim element amended.
