Abstract: 1,131,109. Burnishing. SUNDSTRAND CORP. 26 Sept., 1966, No. 42939/66. Heading B3X. A method of burnishing metal with a diamond comprises causing relative movement between the diamond and a surface to be burnished, and resiliently biasing the diamond into engagement with the surface to be burnished. In apparatus for carrying out the method and for burnishing the radial surfaces 18, 20 of a bearing 16 of a crank-shaft, a pair of diamond tools 40 having rounded ends 48 are secured by clamps 42 to the ends of respective levers 32, Fig. 1, which are located within longitudinal recesses 30 in a support 22 and mounted on pivots 50. Each lever is formed with a pair of recesses 52, Fig. 4, housing springs 56 engaging adjustable abutments 58 in recesses 54 in the support, the springs acting to resiliently urge the tools into their operative positions. The tools are retractable from their operative positions by rocking of the levers about their pivots 50, the rocking being effected by the advancing movement of a tapered cam 108, Fig. 7, adjustably mounted on the rod 106 of a pneumatic or hydraulic motor 102 engaging cam surfaces 118 on the rear ends of the levers 32; the cam 108 is adjustably clamped in a block 106 which slides between guide surfaces 114 on the support 22. The movement of each lever is damped by devices comprising plungers 82, Fig. 6, which are connected to the levers by pins 92 and are formed with flanges 86 disposed between series of resilient rings 98, 100 abutting shoulders in sleeves 64 and 94, the sleeves being adjustable relative to each other and to the support 22. In operation, the apparatus is adjusted by positioning the tools 40 in the clamps and the cam 108 relative to the motor so that, with the tools in their operative position, they can be advanced by a slide carrying the support 22 to burnish the radial surfaces 18, 20 of the bearing, the movement of the tools being damped by the resilient washers. When the tools have been advanced to the fillet of the bearing, the cam 108 is advanced to rock the levers and retract the tools from the surfaces so that the support may be rapidly withdrawn. An oil mist or other coolant may be supplied through a conduit 124 and passages 120 to the tools.

[Classes 100 (i) and 100 (ii)] Stopping and starting arrangements; feeding sheets.-In a postal franking-machine of the kind in which a driving-means is adapted to actuate a printing-mechanism through a single cycle and to drive a conveyer for feeding the envelopes or the like through the machine, a manually-operated mechanism is also provided for actuating the conveyer and for setting the printing-mechanism in operation at each movement of the conveyer. The machine is of the kind described in Specification 445,414 wherein the automatic operations of the machine are controlled by a finger rocked by the mailmatter and adapted to be moved out of the path of the mail-matter for manual operation. The conveyer consists of an endless belt 32 with which, for automatic operation, a double trolley co-operates, the trolley being held in place by a spring-controlled handle. Raising of the handle to enable the trolley to be removed disconnects the conveyer clutch and frees the manual control mechanism which is connected to the shaft 53. A ratchet-wheel 35 is secured to the shaft of the pulley 34 supporting the conveyer belt, and pawls 42 carried by a plate 37 co-operate therewith. The plate 37 is freely mounted on the shaft of the pulley, and is connected with a finger-piece by means of a pin 45 passing through an arcuate slot 46 in the wall of the machine. The finger-piece is under the influence of a spring so that the pawls 42 are normally held out of engagement with the ratchet-wheel 35 against the action of springs 43 by pins 49 so that the shaft can be rotated by the machine without the wear and noise consequent on the movement of the pawls over the teeth. When the finger-piece is rotated, the pawls are released by the pins 49 and rotate the ratchet-wheel to move the conveyer to the extent permitted by the pin 45 and slot 46, thus producing a definite feed of the mailmatter and an even spacing of the franks. The final part of the movement of the plate 37 effects the oscillation of a lever 52 secured to the shaft 53. The lever 52 carries a brake shoe 54 which is brought into position to act on the conveyer belt 32 to prevent overrunning in case the finger-piece is operated quickly.
