Title: Improvements in or relating to Rotary Razor Stropping Machines.
Inventor: GREEN HAROLD JAMES
IPC: B24D15/08
Filed: 1919-02-28
Abstract: 127,221. Green, H. J. Feb. 28, 1919. Stropping-apparatus.-Relates to rotary stropping-machines of the kind in which the razor blade is acted upon simultaneously by two stropping-rollers, disposed one on each side of the blade and rotated by means of a crank-handle. The blade is stropped without being removed from its holder, and the stropping-rollers are normally separated one from the other so as to facilitate the insertion of the blade between them, and are brought into operative position against the blade by either depressing or pulling the razor-supporting means, which are movable relatively to the base of the machine. Fig. 1 shows the stropping-rollers a in their inoperative position, separated from each other bv means of a spring u. When the razor is inserted, as shown in Fig. 4, a downward pressure thereon causes the upper frame g to slide over the base portion q, and flanges s upon the roller-spindle bushes d coact with inclined faces r and cause the rollers to approach each other, the bushes d moving in arcuate slots c. The rollers are then rotated, to strop the blade, by means of a crank-handle (not shown) mounted upon a spindle m, driving the rollers in opposite directions through gearwheels k, j. A coiled spring o, Fig. 3, on the spindle m prevents the crank-handle from being rotated in the wrong direction. The handle is so mounted that, after use, it can be folded inside the frame of the machine. The spindles of the stropping-rollers are rectilinear in section and can be withdrawn from the frame, for renewal, by simply unscrewing a retaining end-plate. Various modifications are described and illustrated in which the roller spindles are carried by pivoted links or bell-crank levers arranged to cause the rollers to move together into operative position by a downward pressure. In other forms, one of the rollers is carried by the razor-supporting means and is moved towards the other by a pull upon the razor handle; or both rollers are connected by link-and-lever mechanism, so that a pull on the razor causes both rollers to move together simultaneously. Finger-plates are attached to the frame to facilitate the application of the pressure or pull.

A ball mill for continuously treating liquids, solid particles in liquids or powdered materials comprises one or more closed containers which are divided into compartments containing loose grinding media by one or more perforated partitions, each container having imparted thereto a motion which is both an angular oscillation and a linear reciprocation. A mill for grinding paint is shown wherein the material from a pre-mixer 7 is fed by a pump 9 through flexible pipework 11 to one end of a pair of grinding containers 5, 6 which are connected in series and removably-mounted at each end of a shaft 4. An eccentric or similar cam device 3 driven by a motor 2 serves to rock the shaft and reciprocate it along its own axis. Each container is divided into two or more compartments by corresponding partitions which are perforated to permit the passage of the ground material but prevent the passage of the grinding media. The ground material passes through the compartments in the containers and is circulated back to either the mixer or pump. More than one pair of containers may be employed and, if desired, interconnected in series, parallel or in combinations of both. Various connections in the pipe lines provide for discharge, sampling, dilution or feeding additives &c. When powdered materials are to be treated, the arrangement of the plant may incorporate a blower instead of the pump 9.
