Vintage Sunbeam Mixmaster - how does it work? - sunbeam mixmaster bowls

I bought an old Sunbeam Mixmaster. It is difficult and rests on the arm give one rotation over a bowl. He came with a series Juicer Attachment: 1) a container with 2 holes, a center and a funnel. 2) a juicer cone ceramic with a metal rod, the center is ticking on the end. 3) a clip in which two parallel metal spikes to about 2 1 / 2 inches long (what is this?) There is a hole in the top of the entire unit, next to the handle seems to reflect the parts of the juicer, but the console of the handle is on the road. On the other side of the handle is a little hole-groove. Could be a key to remove the handle? If not, how? In addition, scouts formed by this unit? The only other evidence I see is 2 black buttons, like shapes on 3 / 8 "diameter. One on each side of the mixer body just below the handle. If one of them to solve a small spring behind him. Has anyone forgotten that this mixer and how do they work? Thanks
