Abstract: 421,074. Machinery guards. KENRICK & JEFFERSON, Ltd., and GIFFORD, R. D., High Street, West Bromwich. July 26, 1933, Nos. 21041 and 31466. [Class 80 (iv)] A guard for a guillotine comprises a bar or bars 5 carried by arms 4 which are moved up to and away from the blade 6 by means of linkwork operated by a roller 13 and cam guide 17. A shaft 3 on which the arms 4 are mounted is carried by adjustable brackets 2 and is oscillated by a rod 8 pivoted to a yoke piece 9 carrying the roller 13. In view of the inclined motion of the knife and the shape of the cam 17 the guard is only moved when the roller is in the horizontal portion 16 of the cam, i.e., when the knife is near its highest position, so that the guard is moved to guarding position early in the down-stroke, and withdrawn late in the upstroke. The yoke is connected by an adjustable link 10 with the end of a rod 11 bolted to the frame of the machine. In a modified construction, Fig. 4, the arms 4 are loose on the shaft 3 and are connected with short arms 19 fast on the shaft by spring clips 20. This device allows of the yielding of the guard if obstructed.

Abstract: 614,499. Welding. A.E.R. (1938), Ltd., and HUNT, C. A. July 16, 1946, No. 21268. [Class 83 (iv)] Aluminium and alloy parts to be welded to like or other metals are subjected to the oxideremoving process described in Specification 597,443, [Group II]. The parts are immersed until uniformly coloured in an aqueous alkaline solution, heated above 60‹ C., comprising 4 to 6 oz. per gallon of an alkali metal hydroxide, at least 6 oz. per gallon each of tin chloride and copper chloride, and for magnesium alloys generally 3 to 4 oz. per gallon of ferric chloride. The metal is washed and immersed until the colour is removed in a bath of concentrated nitric and sulphuric acid, containing copper with or without zinc, e.g. 3 to 4 oz. per gallon of copper or brass scrap. The parts are then washed and welded. The surfaces are preferably degreased before treatment and the alkaline solution should give a 2 to 3 second delay before gassing when the parts are immersed. In a modification, the ferric chloride may be in a separate solution into which the parts are dipped before the acid treatment. The alkaline solution may be made by adding to water the compounds resulting from the chemical combination of the hydroxide and chlorides. Spot, seam, butt and lap welding are referred to.

Title: Improvements in forming means for profile grinding wheels
IPC: B24B53/08
Filed: 1951-09-10
Abstract: 699,544. Dressing grinding wheels. HALLEWELL, H. S. Sept. 5, 1952 [Sept. 10, 1951], No. 21324/51. Addition to 573,877. Class 60. The apparatus of the parent Specification, in which a template follower 18 and a dressing tool holder 28 are rockable about axes perpendicular to the plane of the template 37 and connected by a pantograph 12, 13, 16, 19 and a connection supplementary thereto to constrain them to rock in unison, is modified in that the template may be rotated about an axis B-B disposed in the neighbourhood of the plane of the template and capable of being set parallel to the axis CC of the grinding wheel. The template is also rotatable about an axis A-A perpendicular to the latter axis. Scales 45 and 47 indicate the extent of adjustment about the axes A-A and B-B respectively while lock nuts 42, 43 and 46 hold the template in its adjusted position. The inclination of the template, which is located in relation to a part 35 by straight edges 39 and 40 and secured by screws 38, provides compensation for profile distortion when lathe tools and the like with rake and relief angles are to be ground. The template follower, constituted by a pin with two side wings 48, is mounted in a sleeve 55 and positively coupled by a pin 51 and an arm 52 to a rod 50 rotatable with a shaft 53. The latter carries an operator's hand wheel 54 and a drum 31 connected by tensioned steel tapes 22, 23 and 24 and intermediate drums 25, 27 and 30 to the tool holder. The sleeve 55 bears against a flat face 34A on a bracket 33 supporting the template to prevent distortion of the pantograph by the inadvertent application of excessive lateral pressure. The link 19 is formed by a light alloy casting of inverted channel section with enclosed ends to protect the bearings of the pantograph the weight of which is supported by springs 56. When the template angle required is in excess of that which the template mounting permits, the dressing tool is displaced along its rocking axis to take account of the difference. Specification 699,545 also is referred to.

Abstract: 1278204 Vehicle-mountable scrapers A R EDWARDS 19 April 1971 [11 Feb 1970 5 May 1970] 6455/70 and 21504/70 Heading E1F A vehicle-mountable scraper comprises a scraper blade 10, a pair of wing structures 11, 12 projecting from one face of the blade at or near the ends thereof, and means 15 for so securing the scraper to lift arms 21 mounted on a vehicle that the scraper when secured to the arms will pivot relative to the arms about an axis parallel to said face of the blade and intersecting the wing structures. Such a scraper can thus have the blade correctly presented, without dismounting of the scraper from the vehicle, irrespective of the scraper being pushed or pulled by the vehicle. This presentation is obtained by raising the lift arms so that the scraper will pivot about the axis, the wing structures then pointing upwards, lowering the arms so that the back of the blade will engage the surface to be scraped, and then moving the vehicle either forwards or rearwards to cause the wings to swing down against the surface and point in a direction appropriate to the intended direction of movement of the vehicle. In the embodiment shown the means comprise a shaft 15 extending through the lift arms 21 in a direction parallel to the face of the blade 10 to enter slots 13, 14 in the wing structures. In another embodiment the means comprise two pivot pins disposed parallel to the face of the blade and mounted in connecting lugs projecting forwardly from the blades face. The distance between the blade and the axis is such that a major proportion of the weight of the scraper lies on the blade side of the axis. This condition may be caused by weighting of the blade with a metal strip. The wings are of hollow, wedge shaped construction and the edges of the wings and the blades can be covered by replaceable wear strips of rubber.
