Title: Sharpening apparatus
IPC: B24B3/36
Filed: 1973-12-18
Abstract: 1406149 Sharpening knives AMERICAN OPTICAL CORP 18 Dec 1973 [18 Dec 1972] 58614/73 Heading B3D Apparatus for sharpening a microtome knife 12 comprises means for stroking both sides of the knife in turn against a honing plate 41, and means for selectively applying an increased pressure between the knife and plate. The knife is stroked back and forth on the honing plate which simultaneously is moved with a circular translatory movement. The knife is secured by a clamp 14 carried by a rod 16 which is rockable about an axis 25 on an assembly 20 movable back and forth along guide rods 22, 23 by gearing driven from a motor. The apparatus is controlled so that the knife is moved back and forth three times. During the fourth back and forth movement, a cam 3 co-operates with parts 33-35 on the assembly to rotate rod 16 through 180 degrees about its axis so that the other side of the knife is presented to the honing plate. During coarse sharpening, a solenoid 53 is energized to rock an arm 56 about a pivot 63, the arm being connected by a spring 63 to a second arm 57 to urge a cam 58 against a projection 28a on a lever 28, the action of the spring on the lever causing the knife to be urged with a pressure of, say, four pounds, against the honing plate during coarse sharpening. During turning of the knife, the solenoid is de-energized. The solenoid is also de-energized during fine sharpening when the knife rests by gravity only on the honing plate. The honing plate is carried by a support 42 mounted on a plate 85 connected by eccentric pins 95, 96 on gears 93, 94 driven by a motor 92 whereby the honing plate is moved with a circular translatory motion. The gears and motor are mounted on a plate 86 pivotally connected to triangular plates 116, ... 119 rockable about pivots 121, ... 124 upon movement of plates 126, 127 also pivotally connected to the triangular plates. The plates 126, 127 have notches engaged by cams 106, 107 rotatable by gearing 101, 102 from a control knob 43. During coarse sharpening, the knob is moved so that the plates 116, ... 119 raise the plate 86, and hence the honing plate to an upper position and the blade makes a predetermined angle with the honing plate. During fine sharpening, the knob is rotated to cause lowering of the honing plate and an increase in the angle between the knife and honing plate. A pair of worn honing plates can be re-surfaced by mounting one of the plates above another carried by the support 42. The upper plate is located in an attachment mounted on the apparatus, spring-pressed pads on the attachment pressing the plates face-to-face while the lower plate is moved with the circular translatory motion.

Abstract: 1,254,240. A die-checking and finishing device; finishing. W. REIS. 30 Dec., 1969, No. 63180/69. Headings B3A and B3D. A device for positioning complementary mould or die parts for checking and finishing comprises a base member 7 for supporting a first part 8 to be finished, a slidable member 2 guided for linear displacement relative to the base member 7 by guide members 1a, a support plate 3 for supporting a second part 9 to be finished, and hinge means 4 hinging the support plate 3 to the slidable member 2, the support plate being pivotal between a position parallel to the slidable member 2 and an angular position more than 90 degrees from its parallel position. In operation, a carriage 6 supporting the first part 8 is displaced laterally by drive means 35 after which an hydraulic drive means 5, connected via rod 13 and pin 14 to the plate 3, is actuated so as to pivot the plate 3 through an angle of more than 90 degrees while the cylinder 5a is guided by a rest 16. Connecting rod 13 is then released from plate 3 and the slidable member 2 is moved downwardly by actuating drive 10 which cause plate 3 to swing out still further. The free edge of plate 3 moves on rollers 11 along guide tracks 12 until the second part 9 is horizontal. In second and third embodiments the hydraulic drive means 5 is either (1) hinged about the centre of sliding member 2 so that as member 2 is lowered the cylinder 5a is guided by abutment surface (17), or (2) guided by a chain 18, Fig. 6, passing over a pulley 19. In a fourth embodiment, Fig. 7, pin 14 is held in a claw 20 having a guide surface 21 so that in the position A pin 14 is retained in the claw 20 but as connecting- rod 13 is pushed out to position B the guide surface 21 engages the pin 14 and causes the pin to slide out of the claw. The sliding member 2 is then lowered so that the roller 11 moves down surface 23 until the plate reaches position C after which it is lowered into the horizontal position.

Abstract: 689,415. Electric indicating systems. UNION CARBIDE & CARBON CORPORATION. Jan. 8, 1951 [Jan. 12, 1950], No. 483/51. Class 40 (i). The strata being cut by the rotary cutting head of a mining machine is indicated continuously on an indicator such as a cathode ray tube the circular time base of which is synchronized with the cutter head rotation, by indicating thereon the amplitude and frequency of the vibrations of an auxiliary cutting tooth mounted on the head. As shown, the rotary cutter head 12, Fig. 4 has pivoted eccentrically thereon at 74 an arm 72 to which the auxiliary cutting tooth 10 is secured. The tooth 10 has a tapered shank 53 fitted in a metal sleeve 54 screwed to the arm 72, the sleeve 54 being bonded to a rubber sleeve 58 bonded to a metal sleeve 60 rigid with a bracket 62 welded at 70 to the cutter head 12. The tooth 10 is thus held rigid radially but permitted to vibrate tangentially. Secured tangentially within the arm 72 is a carbon pile 82 compressed through a slug 88 so that tangential vibrations of the tooth 10 cause corresponding variations of the carbon pile resistance due to the inertia of the slug 88. The pile is energized by a battery 17, Fig. 1, the current variations produced by the tooth vibrations being fed over a transformer 46 to produce radial deflections of the beam of a cathode ray tube 42, as shown in Fig. 3. The circular time base is produced by a two phase generator 38 synchronized through a Selsyn transmission system 28, 30 with the cutter head shaft 24. The amplitude and to some extent the frequency of the vibrations varies according to the strata being cut.
