Grimm’s Bum-Making Machine

W.T. Grimm and his non-Grimm partner did not obtain a patent for a bum-making machine. The bleariness of the scanned patent document only makes it look that way. The patent is now listed as:

Bum making machine,” US patent # 2354681, granted to W.C. Grimm et al. on August 1, 1944.
