513 - Looks like a mechanical stage for a microscope. The brass knobs would be used to move the specimen (mounted in the C-shaped portion of the stage) in the x- and y-planes, with the vernier markings on the right side and bottom used to determine coordinates to help re-locate areas of the specimen. The manufacturer (B&L) marked on the device produces microscopes. The only thing that I am uncertain about is what type of specimen the C-shaped area would hold -- it doesn't look like it was designed for conventional rectangular microscope slides. Maybe it was used to hold a small dish that contained live specimens. If this guess is correct, it was a stage for a "dissecting" microscope (reflected light microscope), used to examine surfaces, rather than the more commonly known type of microscope used to examine internal structures (transmitted light microscope).

513. The previous poster is correct. Thanks to the (just barely legible :-) patent date in the photograph, I was able to eventually track down the item to US Patent No. 588,689.
Here is a link to the patent document (with diagrams).
508. This punches paper, cutting on one side of the shape, then folds the punched part back to form a paper "staple".

513. Thanks to Sawdust's great detecive work, I was able to review quite a number of B&L's patents. Here is a link to their innovations from a site that should be of interest to all of us tool fanatics.

Oh, and the 'C' part appears to be the fixed point of the mount, designed to securly hold onto a pipe.
