Abstract: 775,849. Idler rollers for belt conveyers. MEYER, W., and MEYER, T. W., [trading as MEYER & CO.]. April 21, 1955 [Sept. 17, 1954; March 30, 1955], No. 11567/55. Class 78 (1). [Also in Group XXXIV] Sealing means for bearings, especially the bearings of conveyer belt rollers, comprise at least two discs between an anti-friction bearing and a bearing closure, the disc nearest to the anti-friction bearing being fashioned and arranged relatively to a bore through which grease is supplied so that a small proportion of the grease is fed to the antifriction bearing, the greater part being supplied to compartments remote from the anti-friction bearing and behind the other disc. In the construction shown in Fig. 1, the two ends of a roller body 1 are each closed by a cup-shaped piece 2 connected to a tube 3, the piece 2 being mounted on ball-bearings 5 on a journalled shaft 6 provided with bores 8, 9 for passage of lubricant. A bushing 15 fast on the journal 10 has an internal recess 16 and an aperture 17 which is partly obstructed by the edge of a conical disc 18 fitted within the piece 2. Next to the disc 18 is a sealing element 19 of rubber or similar material engaged by a member 23 forming with a disc 24 the cover for the piece 2. A disc 22 with a hub portion 21 is fitted on to the axle journal 10. A small proportion of grease supplied through bores 8, 9, recess 16 and aperture 17 goes to the bearing 5, the remainder entering compartment 20 and eventually passing around behind disc 22. In the construction shown in Fig. 2, the grease is supplied through an opening covered by a spring-pressed valve 36. It may also be supplied through an opening 44 closed by a screw 43. The disc 30 and a cutshaped member 32 are shaped to surround the elastic element 31 which is provided with one or more apertures 40. The sealing device is enclosed within two rings 47, 48 which may be replaced by a single ring with a flange at one end. In the construction shown in Fig. 5 the disc 58 is made of elastic material and is formed with one aperture 64 whilst the sealing element 54 has a plurality of apertures 65, the crosssection of each of which is greater than that of the aperture 64. The sealing element is held against a bushing 61 by a spring 56. In a modification the sealing element and elastic disc are replaced by a single elastic disc having two lips engaging the bushing, the lip corresponding to the sealing element being more elastic than the other lip which may have two small apertures.

Title: Portable power accessory for supplying electricity to remote elec trical appliances
IPC: B63J3/04
Filed: 1972-03-13
Abstract: 1380348 Auxiliaries for ships J L MURRAY 13 March 1972 11702/72 Headings B7S and B7V [Also in Division F2] A boat 14 is supplied with electrical power from a unit 10 which comprises an I.C. engine and a generator inside a waterproof casing, the exhaust discharge of the engine being located under water. The unit may supply the boat only when the latter is stationary or may also be towed by the boat when it is under way. The arrangement reduces noise and vibration and improves safety. The casing of the unit 10 comprises two halves joined at flanges 20 and 22 which, together with fins 94 and 96, help to inhibit rotation of the unit about the drive axis of the engine 34. A casing door 100 is held closed by a spring-loaded catch so that it can blow open if overpressure is generated in the casing. Combustion air is drawn in through a snorkel tube 54 and before reaching the engine passes over the generator 36 to cool it. The engine exhaust pipe terminates in a nozzle 80 which normally faces towards the boat so that the exhaust discharge tends to move the unit to its maximum distance from the boat. A flexible concertina section 78 allows the nozzle to bend away from its forwardly facing position. The nozzle is formed by opposed flexible side walls which, when the exhaust is not discharging, co-operate to prevent the admission of water. A tube 86 enters the exhaust pipe so that the exhaust stream draws any water from the bottom of the casing. The unit includes a fuel tank 42.

Title: Improvements in or relating to sheet feeding apparatus
IPC: B65H3/08
Filed: 1931-04-24
Abstract: 370,673. Feeding sheets. ADDRESSOGRAPH CO., 901, West Van Buren Street, Chicago, U.S.A. April 24, 1931, No. 12231. Convention date, April 24, 1930. [Class 100 (i).] Sheet separators and carriers; pile supports; dropping - roller feeds.-Sheets are fed to a printing-machine from an inclined pile 5 by means of oscillating suction members 58 mounted on a hollow shaft 48 carried by arms 46, 47 pivoted to slides 35, 36 which are reciprocated on guides 37 .. 40 by means of a forked lever 53 which is oscillated by a pitman 56 and a crank on the main drive shaft 19 driven by belt gearing from a motor 24. The action of the lever 53 first raises the nozzles 58 from the full line position, Fig. 2, to the dotted line position, and then the slides 35, 36 are moved with the nozzles to advance the sheet separated by the nozzles from the top of the pile to the position shown near a positively driven roller 17 which coacts with rising and falling rollers 15 operated by a lever arm 28 and cam 31 on the shaft 19. During the forward movement of the separated sheet no pivotal movement of the members 58 takes place. The separated sheet is forwarded by the rollers 15, 17 to a conveyer belt 32 moving over the working table T of a printing-machine. Parallel movement of the slides 35, 36 is ensured by means of links 41 and freely mounted crank arms 43 journalled on the shaft 11 which supports the arms 12 in which the rollers 15 are mounted. Several suction nozzles 58 are mounted on the tube 48, and a spring-pin 62 on each nozzle can engage either of two notches 61, 64 in the tube to hold the nozzle in operative or inoperative position. The inclined plate 67 on which the stack rests is carried by a standard 66 which is raised intermittently by a rack engaged by a pinion operated by means of a pawl and a ratchet 721. The front edges of the sheets register against the fronts of hollow columns 69 which are fitted with apertures 75 to direct blasts of air between the sheets to facilitate separation. The columns 69 are connected by a pipe 85 and check valves 84 to a pump 76 which exhausts the air from the tube 48 by means of a pipe 82 and a check valve 81. The pump 76 is operated by a crank from the shaft 19. To the tops of the columns 69 are secured plates 73 with knife-edges 74 over which the top sheet is drawn to prevent double feed.

Inventor: LIVERTON JOHN JAMES
IPC: G04C3/02
Filed: 1918-07-30
Abstract: 122,592. Liverton, J. J. July 30, 1918. Electric clocks.-The pendulum P is maintained in action by gravity levers G pivoted at Q which are reset by the lever-armatures H of electro-magnets M. Having reached, as shown, the limit of its swing, the pendulum P has dipsplaced the gravity lever G slightly so that the corresponding lever-armature H has fallen from the retaining position to the stop S and the circuit of the electro-magnet of the other leverarmature is completed at the contact A resulting in the elevation of its armature-lever, and thereby of the other gravity-lever. The lever-armature operates at an incline I on the gravity-lever. On the pendulum reversing, the aforesaid circuit is broken and the freed gravity-lever urges it, but the lifted gravity-lever and corresponding lever-armature remain suspended by mutual engagement at a notch in the incline till the pendulum acts on their side The base-plate W is included in the circuits. By contact of the leverarmature with a terminal D current is sent to secondary clocks. Specifications 1587/95 and 7868/97 are referred to.
