Title: Improvements in apparatus for treating metal sheets
IPC: C21D9/46
Filed: 1930-12-03
Abstract: 368,774. Endless chain conveyers. ATKINSON GRIFFITHS NORMALISING CO., Ltd., 47, Victoria Street, London, and GRIFFITHS, E. E., Ennerdale, Linden Avenue, Blundellsands, Lancashire. Dec. 3, 1930, Nos. 36389/30 and 15863/31. [Class 78 (i).] In a continuous furnace for annealing metal sheets, of the kind in which the sheets are detachably secured at their upper edges to supports depending from a conveyer and hang vertically during their passage through the furnace, the supports are arranged to permit of limited movement in both horizontal and vertical directions. As shown, the furnace comprises heating, cooling, and discharge chambers in the upper parts of which is provided 'a chamber to house the conveyer C, the latter being formed of links c<1> carrying brackets c<3> to which are secured longitudinal pivot pins c<12> about which the hanger-bars B pivot. The extent of this transverse swinging movement is limited by jaws c11<1>. The brackets c<3> carry bearing-blocks c<4> which slide on a longitudinal water-cooled tubular guide c<5>, and a guide c<8> is provided for the outer ends c3<1> of the brackets c<3>. The devices for attaching the sheets A to the hanger-bars B are shown in Figs. 10 and 11 as applied to the attachment of sheets having bent-over upper edges a<1> and plain upper edges, respectively. In the former case, the device comprises a hook member F and a gripper G adapted to pivot about the bolt f<1> by which the member F is secured to the bar B ; the bolt hole in the bar B is elongated to permit a vertical movement of the support, this movement being limited by a lug f<5>. The oscillation of the support about. the bolt f<1> in a plane longitudinally of the furnace is limited by the engagement with stops b<5> on an upward extension f<4> of the member F. The gripper G is formed at its.upper end with an ear g<5>, adapted to engage with a longitudinal cam bar to release the gripper at the appropriate times, and at its lower end with a wing g<3>, to engage the outer side of the sheet, and a curved surface g<2> which bears on the upper side of the turned-over edge a<1>. For sheets with plain upper edges, the supports comprise a clamp F<2>, Fig. 11, slotted at f<6> to take the bolt f<1> and having a serrated lower part f<7> formed with a lug f<8> carrying a bolt f<11> on which is pivoted a gripper G<2>. The overhanging end of the latter is either weighted or pressed downwardly by springs so that the sheet is firmly gripped between the serrations f<7> and similar teeth g<6> on the gripper. Release of the gripper is effected by a cam bar g<8> and cam bars f<9>, engaging wings f<10> on the clamp F<2>, are provided to hold the latter rigid when sheets are being attached to or removed from the conveyer. A modification is described in which the teeth g<6> are dispensed with, the serrations f<7> co-operating with a pivoted plate pressed into engagement with the sheet by the lower end of the gripper G<2>. Specifications 324,679, 335,234, [both in Class 78 (i), Conveyers &c.], and 368,767 are referred to.

Abstract: 1,066,497. Opening containers; packages. EKCO CONTAINERS Inc. Sept. 8, 1964, No. 36805/64. Headings B8C and B8D. An aluminium foil container having a coating 21c of heat-sealing adhesive is closed by a laminated cover 22 comprising a wall 24 formed with a pull tab 22T and attached to a removable portion 23P of a lower wall 23 enabling a circular opening (23-1), Fig. 1, to be formed in the cover 22 when the tab 22T is pulled. The wall 24 is a laminate of paper 24P and aluminium foil 24M, and the wall 23 is of aluminium foil which is pre-cut to define the portion 23P. Layers of heat-sealing adhesive 23c, 24c cover the undersides of the walls 23, 24 respectively. By this means wall 24 is heat-sealed to the wall 23 in an annular area 26 and to the portion 23P in an area 26P. The covers 22 may be applied to the containers in stip or group form, or separately, after the containers are filled, e.g. with a volatile burnable substance. Each cover 22 may be formed of two layers of aluminium foil, Fig. 4A, adhered to one another on the same pattern as in Fig. 2. The removable portion in the lower wall may take the form of a group of small circular areas, Figs. 5-7, providing perforations for a salt or pepper shaker. Again, the removable portion may be triangular, Figs. 8-10, to provide a pouring opening; or the container may be of rectangular plan, Figs. 11-13, the removable portion taking the form of a pouring opening in one corner and a vent opening in a diagonally opposite corner. By providing a pull-tab at each of two diametrically opposed positions on a circular container, Figs. 14-16, either half of the cover may be hinged separately about a central division formed by a seal. Each half is re-closable, one providing a segmental opening for a measuring spoon, the other a group of shaker openings.

Abstract: 886,259. Crimping pliers. BUCHANAN ELECTRICAL PRODUCTS CORPORATION. Nov. 2, 1959 [Nov. 10, 1958], No. 37090/59. Class 61. A tool for crimping an electrical terminal on to a conductor includes a die holder having a bore within which a crimping die is disposed, the crimping die being actuated by relative movement between an operating member and a carrier member for the die holder, said tool including a terminal locator which is removably attached to the tool by reversably sliding a locking member relative thereto, said locator closely embracing the extending portion of the terminal and having a stop for engaging said terminal to transversely and longitudinally align the portion to be crimped with the crimping die, the arrangement being such that the locator can be replaced if desired by another of different size. In an embodiment a tool 16 comprises a die holder 18 accommodating spring-loaded crimping dies 22, a channel-shaped carrier member 26 and an operating member 36 having a cam surface 38 encircling the die holder 18 and engaging dies 22. A ratchet mechanism 44 is mounted in the carrier member to prevent divergence of the members 26 and 36 until the desired crimping stroke has been completed. A trigger 46 rotatably mounted in the carrier member is operatively associated with the ratchet mechanism by a lever 48. An adjustable stud 52 on the operating member 36 engages the trigger at the completion of the crimping stroke to release the ratchet mechanism so that rotation of the members 26 and 36 in the opposite direction can take place. Simultaneously, trigger 46 engages a stop 50 positively ending the crimping stroke. A cover plate 58 having an elliptical aperture for the stud 52 is arranged over the trigger to prevent accidental actuation of the trigger. The tool includes a releasable terminal locator 82 (Fig. 11) retained in position by a slide 88 passing through a bridge member 102. In a modification the locator is open at both ends and is provided with an internal annular flange for engaging the terminal ferrule.

[Class 100 (i).] Sheet-separators; sheet carriers and guides.-Sheets, such as folded sheets to be fed to newspaper assembling machines, are separated and forwarded in a diagonal direction from an inclined stack 2 the edges 3, 4 of which are registered against stops 6. The separation is effected by an initial buckling of the lowest sheet by means of a needle separator 12, and the separation is completed by means of two rotary " bell members 9, 10 upon the upper surfaces of which the stack normally rests. The members 9, 10 are formed with apertures 9<1>, 10<1>, and with tongues 11 which enter between the folded bottom sheet and the pile, and bend the lower sheet about a constant bending edge, namely the line of contact of the pile with a rotating roller 7 arranged near an aperture in the pile plate 1. The members 9, 10 are formed with curved frustoconical edges 14 which bend the sheet to conform to the cylinder 7. To ensure that the sheet is gripped between the roller 7 and an apertured roller 8, a pair of rotating rods 15 with eccentrically curved ends 18 presses the forward end of the sheet into contact with the roller 7. When the sheet is gripped between the rollers 7, 8, it is drawn from the pile, and it is finally forwarded by a belt 25 passing over a roller 24 also contacting with the roller 7. The members 9, 10 are rotated by bevel gearing to make one complete rotation for each pair of sheets, and the roller 8 to make one revolution for each sheet fed.
