Title: Devices for use in re-sharpening fluted cutting tools and the like
IPC: B24B41/06
Filed: 1973-06-23
Abstract: 1427957 Sharpening drills JAMES NEILL HOLDINGS Ltd 9 July 1974 [23 June 1973] 29930/73 Heading B3D A device for use in re-sharpening fluted tools, such as drills, comprises means 10, 13 on a body 1, adapted to set a tool 17 in a position whereby one cutting edge is correctly exposed, means 15 on the body to secure the tool in that position, and means 4 adapted to cause oscillatory movement of the tool in a generally longitudinal plane as the device is moved across an abrasive surface. The body 1 is shaped so as to be conveniently held by hand and, at its front, has wheels 3 which form abutment means for engagement with the abrasive surface, and, at its rear, has eccentric wheels 4 which, during movement of the device over the abrasive surface, impart the oscillatory movement to the device. A recess 6 in the body receives a projection 7 of a V-shaped support 8 for the tool 17. The support has an adjustable stop 10 at its upper end and its lower end has a tool setting means 13 which is U-shaped and embraces a projection on the support. The inner arm of the setting means 13 has a flat face for engagement with the tool, the flat face being aligned with the bottoms of the wheels 3. In use, the tool 17 is positioned to engage the setting means with its cutting edge aligned with the bottoms of the wheels. The drill is secured in position in the support by a clamping plate 15 actuated by a screw, and the stop 10 is adjusted along a slot in the support to engage the rear end of the tool. Thereafter the clamping plate is released, a shim 18 swung between the stop and the end of the drill to effect advance of the drill beyond the bottoms of the wheels 3 and the drill is reclamped so that as the device is moved over the abrasive surface the end of the tool is abraded until the wheels 3 again engage the abrasive surface. During movement of the device, the wheels 4 effect oscillation of the body and hence the drill. The drill is then turned through 180 degrees for grinding of the other cutting edge. In an alternative arrangement the tool itself is oscillated on the body.

Title: Improvements relating to devices for inserting photographic film into position for exposure in cameras having curved image surfaces and for discharging the exposed film therefrom
IPC: G03B17/17
Filed: 1954-10-20
Abstract: 758,238. Photographic cameras, film-feeding mechanism. NAAMLOOZE VENNOOTSCHAP OPTISCHE INDUSTRIE DE OUDE DELFT. Oct. 20, 1954 [Oct. 21, 1953], No. 30255/54. Addition to 741,700. Class 98 (1). Photographic film is inserted into and removed from the exposure gate of a camera having a curved image surface by feeding a strip of the unexposed film from a supply spool outside the camera exposure field past cutting means which is also disposed outside the exposure field and which operates to cut off the foremost part of the strip, letting the cutoff poition fall under gravity down guide rails to the exposure gate where it is pressed to conform with the contour of the .image surface during exposure, and releasing it after the exposure. As shown, on each revolution of the motor-driven shaft 18, the diagonal channel of a drunken screw 16 engaging rollers 14 on a gear disc 12 drives this disc and hence a feed roller 5 geared to it and co-operating with an idler roller 4 to feed between them a film strip 3 into the guide rails 30 so that the leading edge of the film projects into the exposure field no more than the required image size. The feed then stops due to the engaged roller 14 entering the straight portion 15 of the feed screw and a cam 19 on shaft 18 causes the blade 25 to cut the film against the edge 25a. The cut portion of film then falls under gravity into the exposure gate 9 against which it is pressed by the.curved pressure plate 10, operated by cam 19 through arms 20, 22 on a shaft 21. After exposure, continued rotation of the shaft 18 releases the pressure plate and the film falls into a storage chamber 27.
