     BACKGROUND—FIELD OF INVENTION AND PRIOR ART 
     As far as known, there are no special automatic out the front knife transformed as a bayonet or the like. It is believed that this product is unique in its design and technologies. 
     BACKGROUND 
     A background as to bayonets and spring knives is useful. A bayonet mount is a fast, secure, and precise way to join two pieces of equipment temporarily. This mount employs two or three pins or wedges that are positioned into slots or grooves of another piece. The connection is made with a twist and a compression force of one piece into the other. This coupling mechanism was first used by the French around the 1670s. Earlier soldiers had discovered the effectiveness of jamming knives into the barrels of their muskets once engaged in close-quarter battles. The disadvantage of the adaption was that the muskets could not be fired until the knives were removed. Gunsmiths set to work on this problem and developed a short tube that fit over the end of the barrel and was locked in place by use of a pin through a zigzag slot. The blade was welded to the side. Peaceful applications of the bayonet mount became plentiful with the development of manufacturing standards and engineering drawings with matched tolerances for connecting equipment. They are commonly used in camera equipment to attach a removable lens to the camera body. The precision alignment of the tight-tolerance pieces ensures the face of the lens is parallel to the camera body, avoiding distortion of the picture. 
     A bayonet lug is a standard feature on most military muskets, rifles, and shotguns, and on some civilian longarms. It is intended for attaching a bayonet, which is typically a long spike or thrusting knife. The bayonet lug is the metal mount that either locks the bayonet onto the weapon or provides a base for the bayonet to rest against, so that when a bayonet thrust is made, the bayonet does not move or slip backwards. Less than 400 years ago, bayonet lugs or their predecessors that allowed them to slip over the barrel did not exist. Prior to the lug&#39;s invention, bayonets merely stuffed into the muzzle&#39;s end from a tight-fitting stub, rendering the firearm virtually useless and certainly preventing it from being discharged. But by the late 17th century, this type of bayonet was entirely phased out and subsequently replaced with the socket bayonet that slides over the muzzle with the blade offset to the side, just above or underneath. Bayonet lugs are usually located near the muzzle end of a musket, rifle, or other longarm barrel. The lug is occasionally placed on top of the barrel, if serving as the base of the front sight, or more often mounted to the side or bottom of the barrel. 
     To couple and attach the two parts, the pin(s) on the male are aligned with the slot(s) on the female and the two pushed together. Once the pins reach the bottom of the slot, one or both parts are rotated so that the pin slides along the horizontal arm of the L until it reaches the “serif”. The spring then pushes the male connector up into the “serif” to keep the pin locked into place. A practiced user can connect them quickly and, unlike screw connectors, they are not subject to cross-threading. To disconnect, the two parts are pushed together to move the pin out of the “serif” while twisting in the opposite direction than for connecting, and then pulling apart. The strength of the joint comes from the strength of the pins and the L slots, and the spring. To disengage unintentionally, the pins must break, the sleeve into which the connector slides must be distorted or torn enough to free the pins, or the spring must fail and allow the connector to be pushed down and rotate due to, say, vibration. It is possible to push down the connector and rotate it, but not far enough to engage and lock; it will stay in place temporarily, but accidental disconnection is very likely. 
     Switchblade knives were invented in the early part of the 20th century. During the 1950&#39;s the switchblade got a bad reputation as it was identified with gangs which were popularized by such movies as “On the Waterfront”, etc. As a result in the late 1950&#39;s most states passed laws outlawing the possession of switchblade knives. A Federal statute was passed to make it unlawful to ship switchblades across state lines, unless being shipped to a law enforcement or military agency. Here we will explain the difference between illegal switchblade knives, and legal spring assisted opening knives. All switchblades have some characteristics in common. They have a spring which exerts constant pressure on the blade. The knife is held in the closed position by the mechanism of the knife. This mechanism is released by depressing the button (which all switchblades have), allowing the stored energy the spring is exerting on the blade to propel the blade from the handle and open the knife. It is important to remember that the natural position of the switchblade knife is OPEN, it is held closed only by the locking mechanism. On the other hand, the natural position of the spring assisted opening knife is CLOSED. There is no pressure being exerted upon the blade, and there is no button to push. Spring assisted knives employ the following opening methods. 1) A “Flipper” or lever which is located on the back spine of the knife. This flipper is actually an integral part of the blade which protrudes from the back spine of the knife when it is in the closed position. This is the most common opening mechanism of spring assisted knives. 2). A thumb stud, the same as is found on most all tactical folding knives. In either case, either flicking the “flipper” or pushing out the thumb stud begins opening the blade, at which point the assisted opening mechanism takes over and finishes opening the blade. Performance wise, there is very little (if any) difference in the opening speed of a switchblade and a spring assisted knife. However, the differences in the way they are made make the spring assisted knives legal in all 50 U.S. states (They are not legal in the 5 boroughs of New York City, but this is because all locking blade knives have been held to be illegal in NYC, not just the spring assisted ones). 
     Problem Solved 
     The improvement and problem solved as to bayonets and spring knives should be useful. A bayonet mount is a fast, secure, and precise way to mount but the ever-present knife blade presents a risk to personnel and equipment when the “blade” is not needed. However, the time to assemble and remove a fixed bayonet can be cumbersome and a delay can prove deadly. The ability to have the Automatic out the front knife transformed as a bayonet resolves the ever-present and potentially dangerous blade as well as the time to place and secure a traditional bayonet. 
     PRIOR ART 
     The improvement and problem solved as to bayonets and spring out front knives have some historical prior art. However they do not solve the problem effectively as the present Rockwell device. The device taught by Tomanek in U.S. Pat. No. 1,290,807 issued in 1919 shows a spring loaded device for a rifle but lacks the simple attachment and few parts in comparison with the Rockwell device. Another device by U.S. Pat. No. 2,330,637 issued to Spagnolo in 1943 reveals a hinged flip-op knife with more complexity and less universality than Rockwell&#39;s invention. 
     Another U.S. Pat. No. 1,055,416 issued to Pliones and Collias in 1913 provided a complex spring activated knife for a rifle or shotgun but failed the simple configuration shown with the Rockwell device. U. S. Pat. No. 2,665,478 by Clemens in 1954 is a leg/shin mounted knife which fails the form, fit and function of the Rockwell out-the-front knife device. 
     Another U.S. Pat. No. 5,722,169 by Ozden issued in 1998 taught a pointed weapon with a springing device. Here was taught a springing, pointed device absent from a weapon such as a rifle or shotgun. It does not anticipate the Rockwell invention. Another U.S. Pat. No. 1,260,827 shows a forward thrust and disappearing bayonet. Issued to Stefanov in 1918, the device appears more complex than Rockwell and limited to certain military rifles. 
     In 1919 a U.S. Pat. No. 1,314,672 was issued to Kozlowski that taught an “automatic bayonet”. This is far more complex and less flexible than Rockwell. Finally, a U.S. Pat. No. 545,528 issued to Paul in 1895 revealed a specialized knife/bayonet used with a pistol. It was limited as used with universal weapons as taught by the instant Rockwell device.

     Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which these inventions belong. Although any methods and materials similar or equivalent to those described herein can also be used in the practice or testing of the present inventions, the preferred methods and materials are now described. All patents and publications mentioned herein, including those cited in the Background of the application, are hereby incorporated by reference to disclose and described the methods and/or materials in connection with which the publications are cited. 
     The publications discussed herein are provided solely for their disclosure prior to the filing date of the present application. Nothing herein is to be construed as an admission that the present inventions are not entitled to antedate such publication by virtue of prior invention. Further, the dates of publication provided may be different from the actual publication dates which may need to be independently confirmed. 
     Other embodiments of the invention are possible. Although the description above contains much specificity, these should not be construed as limiting the scope of the invention, but as merely providing illustrations of some of the presently preferred embodiments of this invention. It is also contemplated that various combinations or sub-combinations of the specific features and aspects of the embodiments may be made and still fall within the scope of the inventions. It should be understood that various features and aspects of the disclosed embodiments can be combined with or substituted for one another in order to form varying modes of the disclosed inventions. Thus, it is intended that the scope of at least some of the present inventions herein disclosed should not be limited by the particular disclosed embodiments described above. 
     Thus the scope of this invention should be determined by the appended claims and their legal equivalents. Therefore, it will be appreciated that the scope of the present invention fully encompasses other embodiments which may become obvious to those skilled in the art, and that the scope of the present invention is accordingly to be limited by nothing other than the appended claims, in which reference to an element in the singular is not intended to mean “one and only one” unless explicitly so stated, but rather “one or more.” All structural, chemical, and functional equivalents to the elements of the above-described preferred embodiment that are known to those of ordinary skill in the art are expressly incorporated herein by reference and are intended to be encompassed by the present claims. Moreover, it is not necessary for a device or method to address each and every problem sought to be solved by the present invention, for it to be encompassed by the present claims. Furthermore, no element, component, or method step in the present disclosure is intended to be dedicated to the public regardless of whether the element, component, or method step is explicitly recited in the claims. 
     The terms recited in the claims should be given their ordinary and customary meaning as determined by reference to relevant entries (e.g., definition of “plane” as a carpenter&#39;s tool would not be relevant to the use of the term “plane” when used to refer to an airplane, etc.) in dictionaries (e.g., widely used general reference dictionaries and/or relevant technical dictionaries), commonly understood meanings by those in the art, etc., with the understanding that the broadest meaning imparted by any one or combination of these sources should be given to the claim terms (e.g., two or more relevant dictionary entries should be combined to provide the broadest meaning of the combination of entries, etc.) subject only to the following exceptions: (a) if a term is used herein in a manner more expansive than its ordinary and customary meaning, the term should be given its ordinary and customary meaning plus the additional expansive meaning, or (b) if a term has been explicitly defined to have a different meaning by reciting the term followed by the phrase “as used herein shall mean” or similar language (e.g., “herein this term means,” “as defined herein,” “for the purposes of this disclosure [the term] shall mean,” etc.). References to specific examples, use of “i.e.,” use of the word “invention,” etc., are not meant to invoke exception (b) or otherwise restrict the scope of the recited claim terms. Other than situations where exception (b) applies, nothing contained herein should be considered a disclaimer or disavowal of claim scope. Accordingly, the subject matter recited in the claims is not coextensive with and should not be interpreted to be coextensive with any particular embodiment, feature, or combination of features shown herein. This is true even if only a single embodiment of the particular feature or combination of features is illustrated and described herein. Thus, the appended claims should be read to be given their broadest interpretation in view of the prior art and the ordinary meaning of the claim terms. 
     As used herein, spatial or directional terms, such as “left,” “right,” “front,” “back,” and the like, relate to the subject matter as it is shown in the drawing FIGS. However, it is to be understood that the subject matter described herein may assume various alternative orientations and, accordingly, such terms are not to be considered as limiting. Furthermore, as used herein (i.e., in the claims and the specification), articles such as “the,” “a,” and “an” can connote the singular or plural. Also, as used herein, the word “or” when used without a preceding “either” (or other similar language indicating that “or” is unequivocally meant to be exclusive—e.g., only one of x or y, etc.) shall be interpreted to be inclusive (e.g., “x or y” means one or both x or y). Likewise, as used herein, the term “and/or” shall also be interpreted to be inclusive (e.g., “x and/or y” means one or both x or y). In situations where “and/or” or “or” are used as a conjunction for a group of three or more items, the group should be interpreted to include one item alone, all of the items together, or any combination or number of the items. Moreover, terms used in the specification and claims such as have, having, include, and including should be construed to be synonymous with the terms comprise and comprising. 
     Unless otherwise indicated, all numbers or expressions, such as those expressing dimensions, physical characteristics, etc. used in the specification (other than the claims) are understood as modified in all instances by the term “approximately.” At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the claims, each numerical parameter recited in the specification or claims which is modified by the term “approximately” should at least be construed in light of the number of recited significant digits and by applying ordinary rounding techniques. 
     With this description it is to be understood that the special automatic out the front knife transformed as a bayonet  30  is not to be limited to only the disclosed embodiment of product. The features of the special automatic out the front knife transformed as a bayonet device  30  are intended to cover various modifications and equivalent arrangements included within the spirit and scope of the description.
