Abstract: 1,173,988. Advancing mine roof support systems. GEWERKSCHAFT EISENHUTTE WESTFALIA. 23 Nov., 1967 [13 Jan., 1967], No. 53390/67. Heading E1P. Piston rods 8, 8' of shifting cylinders 6, 6' are connected to a rail 17 of a conveyor 16 by sliding elements 11 which have pins 12 extending into slideways 13 of members 14. The amount of free movement of the pins in the slideways corresponds to the amount of displacement of the conveyor during the passage of a coal plough (not shown). Rails 4" which connect prop support plates 2 guide a rod 19 also connected to the conveyor rail 17. Rails 4' connecting two other support plates are extended for connection with the rear portions of the cylinders 6, 6'. As shown, cylinder 6 has been charged and the lost movement in. its connection 11-14 has been taken up. To allow for movement of the conveyor at such a time, a pressure relief valve 22' is provided. In a modification, Figs. 2, 3, the rear end of a shifting cylinder 35 is connected to the conveyor 16 by a universal joint 37, two rods 19 and a lost-motion connection having pins 12 and slots 11 in a member 14'. The rods 19 are supported by arms 31 of frame members 32, and a piston rod 36 is connected to the support assembly by a transverse yoke 34 and a connection 38. The connections at 37, 38 may be provided at points higher than those shown. Alternatively, a second shifting cylinder engaging a transverse yoke which connects roof girders may be provided where thick seams, and accordingly greater prop heights, are worked. In the Fig. 1 embodiment, more power is available for moving the conveyor than is available for drawing up the support assembly since a greater piston area is subjected to the hydraulic pressure. In the other illustrated embodiment however, more power is available to draw up the support assembly than is available for the conveyor.

Title: Apparatus for Forming Packages of Articles by Banding in a Heat Shrunk Plastic Film
IPC: B65B9/06
Filed: 1967-12-08
Abstract: 1,175,909. Packaging articles in groups; endless conveyers. " AUTOMATIC " SPRINKLER CORP. OF AMERICA. 8 Dec., 1967 [9 Jan., 1967], No. 55868/67. Headings B8A and. B8C. [Also in Division F4] In a machine forming and shrinking a plastics tube about articles fed in an abutting line, the articles are spaced into groups by separating means provided on each of a pair of driven endless conveyers mounted one at each side of the line of articles. One such conveyer 16 is shown in plan in Fig. 6 engaging a double line of cans 12. The cans are driven by projections 17 in the conveyer and are spaced by projections 20 when these are moved rearwardly from a position A in which they coincide with the projections 17 to a position A<SP>1</SP> spaced rearwardly from the projections 17. As shown, the projections 20 are spring-biased to the latter position and are moved to the former position by a rack-and-pinion mechanism carried by the conveyer and operated by a fixed cam 25. A further cam 29 may assist the spring to move the projections 20 to their separated position. The projections act to batch the cans after they have been wrapped loosely in a web tubed by means 14, Fig. 1, not described in detail. The web is subsequently cut by a guillotine 73 and heat shrinking is completed in a tunnel 110. Finger holes are punched by members 126. Heat shrinking tunnels.-The articles are conveyed on a roller conveyer 49, Fig. 5, through a tunnel 31 which allows for hot air to be blown through its base and through holes 239, Fig. 3, in its roof. The tunnel can be raised by screws 34 when the conveyer line is stopped and this causes flaps 40 (Fig. 5) to close the air ducts supplying air to the base of the tunnel, and causes a slide 43, Fig. 3, to close the air holes in the roof. Pneumatic shockabsorbers restrain the movement of the tunnel. The second tunnel is of similar construction. Cutting the web.-The web is cut by blades 70, 71, Fig. 10, reciprocating transversely with a rapid operating stroke and a slow return stroke. Each blade is of W-shape and cuts through over half the tubed web. Carriages 73 carrying the blades are reciprocated in the direction of movement of the packages in antiphase, the carriages being joined by a rocker arm 102 and the reciprocating motion being derived from a cam 96. The blades are driven through a friction connection which can yield to limit the forces on the blades. The wrapped cans are conveyed past the guillotine by upper and lower conveyers 60, 61, Fig. 1, which engage the cans through projections 62 of foamed silicon rubber. These projections include guides (66) (Fig. 11, not shown) which receive the blades cutting the tube. Adjustments for different sizes of package.- Each of the conveyers may be replaced by a conveyer for forming packages of a different size.

Title: Automatic toaster
IPC: A47J37/08
Filed: 1966-12-16
Abstract: 1,116,478. Automatic toaster. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 16 Dec., 1966 [20 Dec., 1965; 29 July, 1966], No. 56523/66. Heading A4D. An automatic toaster is characterized by the way in which the bread support is moved into the toasting position and is then automatically returned to the bread removing position upon completion of toasting. When a piece of bread is placed on the bread support 9 the latter is displaced and causes latch 60 to push against rod 58 which in turn causes latch lever 47 to move and so disengage hook 49 from the engaging member 48 of the levers 10 and 11 so that these pivot and bring the bread support down into the toasting position. The movement of latch lever 47 also causes the main switch to move to the closed position so that a current flows through the heaters 4. The heat causes the bimetallic elements 68 to move hence opening an auxiliary switch and allowing current to flow through resistance wires 24 which elongate due to the heat generated therein. As the resistance wires elongate connecting rod 56 is lowered so that it causes main lever 44 to pivot hence moving latch lever 47 upwards while at the same time switch operating rod 37 moves downwards and is finally engaged under the hook 51. The movement of rod 37 causes the main switch 29 to open. Opening of the main switch interrupts the current flow and so resistance wires 24 begin to contract pulling connecting rod 56 upwards. Latch lever 47 also moves upwards because hook 51 is in engagement with rod 37. This upward movement of latch lever 47 takes place against the bias of main spring 52 and thereby energy is accumulated in said spring. When latch lever 47 has reached a predetermined elevated level the hook 49 engages over the engaging member 48 of the lever 10 and the resultant displacement of latch lever 47 releases hook 51 from engagement with rod 37. Latch lever 47 is thus moved into an unsupported position so that it is pulled down by the spring force produced by the energy which has been accumulated in the main spring 52 and depresses engaging member 48, which is in engagement with hook 49, whereby the bread support is returned to the bread removing position. Retoasting of the bread is prevented by a lug on the wall 3 which is engageable with a projection of latch 62.
