Abstract:
A bullet loader method and apparatus that enables a user to easily load bullets into a gun magazine. The gun magazine is inserted into the apparatus magazine opening. Bullets are individually loaded into the bullet loader with a grooved cam, so that the individual bullets rest in the groove. The cam is rotated so that the bullet travels within the groove(s) of the cam and pushed with a cog attached to the end of the groove into the magazine. The bullet is pushed into the magazine with both a downward and inward force to overcome the spring resistance of the magazine.

CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims the priority benefit of U.S. Provisional Application 62/062793 filed Oct. 10, 2014, which is herein incorporated by reference in its entirety. 
    
    
     TECHNICAL FIELD 
     The present disclosure relates to loading gun magazines with bullets. More particularly, the disclosure discusses a mechanical and automated method and system for efficiently inserting bullets into the magazines. 
     BACKGROUND 
     The statements in this section merely provide background information related to the present disclosure. Accordingly, such statements are not intended to constitute an admission of prior art. 
     Loading bullets in gun magazines can be time consuming and difficult. Bullets need to be manually inserted one-by-one in a magazine with both a downward and an inward force. The forces needed to insert the last few bullets can be excessive, since magazines have internal springs that become fully compressed with the last few bullets. Loading a full magazine is difficult for anyone and impossible for some people. 
     BRIEF SUMMARY OF THE INVENTION 
     In one embodiment, a bullet loader comprises a housing with an internal cam, wherein the cam has a first indentation configured to loosely hold a bullet, a second indentation which forms a half-cylinder shape, a third indentation configured to loosely hold the bullet, and a fourth indentation with a cog at an end. 
     In a separate embodiment, the bullet loader further comprises a handle attached to the internal cam that enables a user to rotate the cam. 
     In one embodiment, the handle and cam rotate 180 degrees from the start of bullet loading to the insertion of the bullet into the magazine. In separate embodiment, the rotation is 360 degrees. Total rotation of the cam and handle from the start of bullet loading to the insertion of the bullet into the magazine can vary from 90 to 360 degrees, depending upon the embodiment used. 
     In a separate embodiment, the cam further comprises a notch configured to enable the cam to be seated within the housing. 
     The housing can comprise two mirrored sections for easy assembly of the bullet loader. The housing has a magazine opening to insert a magazine and a feed opening to insert a bullet. In a separate embodiment, the housing has a rocker switch to lock a magazine into place. 
     The first indentation can have a depth from 5% to 50% of a bullet&#39;s diameter. 
     The second indentation can have a depth from 50% to 150% of a bullet&#39;s diameter. 
     The third indentation can have a depth equal to 5% to 75% of a bullet&#39;s diameter. 
     The fourth indentation can have a depth equal to 5% to 75% of a bullet&#39;s diameter. 
     In a separate embodiment, the indentations can be merged into one continuous indentation with regions that have greater depth and regions that have lesser depth. 
     In a separate embodiment, the bullet loader further comprises a hopper attached to the feed opening that is configured to automatically feed bullets into the feed opening in the proper orientation (bullet tip facing away from the magazine). 
     A method embodiment of using the bullet loader described above comprises: inserting a magazine into the magazine opening of the housing; locking the magazine into place with the rocker switch; aligning the cam so that the first indentation is aligned with the feed opening; inserting a bullet; rotating the cam to the second, third, and fourth cam positions consecutively so that the bullet is inserted into the magazine with both a downward and inward force; and iteratively repeating aligning, inserting, and rotating steps until the magazine is filled; unlocking the magazine with the rocker switch; and pulling the magazine out of the bullet loader. 
     The scope of the invention is defined by the claims, which are incorporated into this section by reference. A more complete understanding of embodiments on the present disclosure will be afforded to those skilled in the art, as well as the realization of additional advantages thereof, by consideration of the following detailed description of one or more embodiments. Reference will be made to the appended sheets of drawings that will first be described briefly.

Step  3 : the user inserts a bullet into the feed opening and first cam indentation with the tip of the bullet facing away from the magazine. Step  4 : the user rotates the handle and cam to position  2 , so that the bullet rests in the second cam indentation. Step  5 : the user rotates the handle and cam to position  3 , so that the bullet rests in the third cam indentation. Step  6 : the user rotates the handle and cam to position  4 , so that the bullet rests in the fourth cam indentation. Step  7 : the user rotates the handle and cam so that the bullet reaches the magazine. Step  8 : the user rotates the handle and cam so that the bullet is inserted into the magazine, by generating a downward and inward force on the bullet in relation to the magazine. User repeats Steps  2  through  8  until as many bullets are loaded as desired. Step  9 : user engages the rocker switch spring and removes the magazine from the magazine loader.
