Every one, undoubtedly, has experienced the inconvenience of dining on a tough beefsteak,a machine for the purpose of rendering this viand as tender, after going through the process, as it was before the operation the reverse, has been invented by John Lyon, of Enfield, . ., who has taken measures to secure a patent. The machine consists of two corrugated rollers, one of which is adjustable, arranged in sliding bearings and placed horizontally one above the other, between which the steak is passed. The upper roller is connected to springs by means of vertical adjusting screw rods, so that it will suit itself to steaks of varying thickness. The apparatus is enclosed in an iron frame, and the rollers are set in motion by cog-gearing, which is operated by a crank.
