摘要： 161,686. Hardy, A. Jan. 15, 1920. Sheet carriers, separators, and registering devices; pile tables and supports.-In a machine for separating and feeding sheets from a pile to a wrapping or like machine, the sheets are fed from a magazine comprising a baseplate d, supported by side frames a connected by tie-bolts b formed with parts of different diameters, the magazine being composed of side plates y and being open at the rear end and formed at the front end with corner pieces 3 with an opening between and with springs 9 formed with hooks or the like 10 which support the front end of the pile. The sheets at the rear end of the pile are kept in a curved condition by spring-controlled curved members 6 which are fitted in recesses in the plates y and are arranged above the level of the support d. The bottom sheet is separated by means of an oscillating plate 12 fitted wth suction orifices and connected by a flexible pipe 17 to a pump n, Fig. 2, the piston r of which is operated by a lever o operated by a cam u on a shaft h which depresses the piston against the action of a spring w. The plate 12 is controlled by a lever arm 15 and cam 13 and after engaging the bottom sheet is moved to the position shown in Fig. 10 when an oscillating arm 19' is raised to take the sheet from the plate 12 which is cut away to allow the grippers 19, 20 carried by an arm 19 to take the sheet 38 from the plate 12 and carry the same to the position shown in Fig. 10, the grippers before opening passing between a pair of upright gauges 36 which register the sheet as it is deposited on to mechanism which forwards the sheet to the wrapping or like machine. The gripper arm 19' has a pin-and-slot connection with an oscillating gear wheel 24x on a shaft m which is oscillated by a rocking sector 35, Fig. 4, oscillated by a cam on the main shaft h which is operated by hand or power. The movable jaw 20 of the grippers is moved for opening and closing by a cam 23 and arm 25 on the pivot 21 of the gripper, a spring 22 normally closing the gripper.

摘要： 145,958. Hardy, A., Hunt, J. H., and Wigglesworth, M. June 5, 1919. Muffle furnaces.-In a gas-fired furnace for the heat treatment of metal articles of the kind comprising a chamber d surrounded by transverse flues c, through adjacent ones of which the heating-gases flow in opposite directions, the flue b leading from the gas-producer has on opposite sides inclined outlet ports b adjacent to ports e delivering air from recuperators having superimposed gas-waste flues c arranged zigzag fashion with intervening spaces e for heating the secondary air. The ports e are curved at their upper parts to direct the streams of air into the gas issuing from the ports b , and the flues c are separately controlled by dampers c . The door and door frame of the muffle are ground and inclined to ensure a good fit.

摘要： In a method of lining metallic bodies such as brake drums, the liner, which may be a strip of the steel alloy known as "Nitralloy" and containing carbon, silicon, manganese, nickel, chromium and aluminium, is cut to a length and width corresponding to the width and circumference of a brake drum and is fitted therein with its ends juxtaposed, the liner being then subjected to a process of nitrogenization, whereby it is caused to harden and "grow," by applying a protective covering of sodium silicate or barium or potassium chloride to the drum itself and then placing it in a gastight box to which ammonia gas is supplied, a temperature of about 500 DEG C. being maintained.

摘要： 220,746. Hardy, A., and Johnson, L. K. June 12, 1923. Cameras, roll-film, masking in; roller-slides. -In a camera adapted to take spools of difterent widths, the spools are mounted on holders comprising end plates 15, 16, Fig. 7, with the centering pins and telescopic arms 17, 18, which are connected by a retracting spring 21. The spool housings, Fig. 1 and 5, have a series of slots 33, corresponding to different widths of films into which the peripheral sections 31 of the discs 15, 16 fit and the spool-holders are held in position by the projections 32 against which the back cover 2 abuts. For the winding- on spool the turning disc 24 and an inner disc 25, Fig. 5, carrying the stud 28 for the, winding end of the spool are screwed together and shaped to form a peripheral groove 27 engaging a stamped-out edge of an opening in the plate 15. The recesses 29, 30 are engaged by the end 49 of a retractable winding stem 45. This stem rotates with the sleeve 39 and can telescope within it against the action of the spring 47 and the sleeve 39 itself can telescope a limited extent within an outer casing 36 against the action of the spring 40 so as to allow the forked head 49 to come within the side panel of the camera when the largest spool is used. The casing 36 is mounted between an outer bracket 38 and an inner flanged plate 37 which is flush with the inner face of the camera, and this casing 36 is turned by the winding handle 44 and cross-bar 41. To prevent the winding handle being turned backwards, spring-positioned rollers 52 are interposed between the retaining flanges of the plate 37 and inclined cam faces 53 carried by the casing 36. A series of nesting masks 55 is provided within the camera frame, the inner mask being of a size corresponding to the film used, and the film is pressed on to the rear face of the masks by a pressure plate 56 with flat springs 57 contacting with the outer cover 2. Inclined inspection slots 58 in the cover 2 and plate 56 are provided to allow inspection of the numbers on the different sizes of films.

摘要： 392,581. Liners for brake drums and other articles. BERSEY, F. T., HARDY, E. A., NEWSON, S. C., and LAYSTALL MOTOR ENGINEERING WORKS, Ltd., Laystall House, Ewer Street, London. Nov. 19, 1931, No. 32083. [Class 103 (i).] A method of securing a metallic liner to a metallic body, for example, a brake drum, consists in interposing a ring of ductile metal between the body and the liner and then subjecting the liner to a chemical or like process, for example nitrogenization which causes the liner to permanently expand or " grow." The liner c and the brake drum or body a may each have projections d, e which as a result of the expansion of the liner become embedded in the ductile ring b. The liner c may be a steel alloy containing carbon, silicon, manganese, nickel, chromium, and aluminium. The ring b may be of aluminium, brass, copper or other good heat-conducting metal to assist the dissipation of the heat during braking. In carrying out the process the parts are assembled as shown and a protective coating which may be of sodium silicate, barium, or potassium chloride is applied to the drum which is then placed in a box heated in a furnace and subjected to the action of ammonia gas. Specification 372,401 is referred to.
