Title: Improvements relating to apparatus for the moulding of butter and like products
IPC: A01J21/02
Filed: 1945-07-13
Abstract: 613,517. Butter &c. moulding-machines. BELL MACHINERY PROPRIETARY, Ltd., J., and O'CONNEL & KERR PROPRIETARY, Ltd. July 13, 1945. No. 17949. Convention date, May 18, 1944. [Class 87 (ii)]. In an apparatus for moulding butter, &c., the moulds 2, Fig. 3, carried by a rotatable sleeve 4, pass in succession under a cover plate 9 and are filled with butter or the like through a pipe 7. Bottom pistons 10 carry rollers 13 which during the filling operation engage a rod 18 and force down a piston 17 against a constant air pressure, to ensure that the butter is compacted. Each piston 10 carries an arcuate plate 20 which, when the piston reaches its lowest position, closes a spring-loaded switch on the platform 15, causing an electromagnet to engage a clutch which connects the constantly running electric motor to a worm driving a wheel 32 driving the sleeve 4 carrying the moulds. Each plate 20 is shaped to release the switch as the next mould reaches the filling position. During movement of the moulds, butter entering through the pipe 7 passes temporarily into the cylinder 33; displacing the spring controlled plunger 34. The pistons 10 are raised to eject the moulded blocks by engagement of the rollers 13 with a cam track 14. The platform 15 may be adjusted vertically to alter the size of the moulded blocks by turning the nuts 36 by means of the chain 39 which meshes with a sprocket rotatable from outside the casing 1. Part 14b of the cam track 14 is fixed to the casing 1 to ensure that the rollers 13 reach the correct height to engage the rod 18. In a modification, Fig. 8, the moulds 43 are filled from the bottom through the pipe 48 which has a relief cylinder 561 similar to the cylinder 33 above, and the filling of each mould causes a plate 51 to close a switch 52 and rotate the machine, as above. Rollers 54 carried by the mould pistons 49 run on a cam track 55 to hold the pistons in their raised position until the filled moulds reach the discharge position, where they cause the moulded blocks to be discharged on to a conveyer belt 78. The cam track is provided with a safety ramp adjacent the filling position to raise the rollers 54 if the machine should rotate with moulds unfilled. By means of a tappet 69 on each roller bracket 53, and linkage 72 the filling of each mould causes a scraper to pass across the bottom of the mould at the discharge position to ensure detachment of the moulded block from the piston 49. The size of the blocks is determined by the height of the switch 52 and cam track 55, which are adjusted by turning the screwed rods 59 by means of the chain 63 and hand wheel 65. The weight of the pistons 49 and associated parts ensures that the butter is compacted in the moulds.

Abstract: 104,490. Marks, E. C. R., (Corona Typewriter Co.). Jan. 25, 1916. Folding type-lever machines; letter-spacing mechanism.-In the folding machine described in Specification 103,508, the universal bar and the escapement are mounted on the same part of the frame in such a manner that the machine can be folded without separating the escapement from the universal bar; an improved escapement of the anchor type is described. As shown, the frame consists of a part 11 pivoted at 12 to a base 10, the carriage 20, a universal bail 61, and escapement mechanism 70, 78 being supported on the part 11, and a type-lever action and case-shift mechanism being mounted on the base 10. The universal bail 61 is mounted on a bracket 67 secured to the rear bar 28 of the part 11, the bail being suspended by two pairs of links 63, 64 secured to shafts 65, 66. One link 64 is pivoted to and engages a shoulder on a link 68 coupled by a link 69 to an anchor 70, which co-operates with an escapement wheel 78. A returning-spring 71 is connected to one of the arms 64. The universal bail is operated by the type-levers and also, as described below, by a lever 77, Fig. 2, connected to the space-key 72. The type-levers strike the bail at about the middle of their length, thus producing a quick action; moreover, since the type-levers have a normal position and two shift-positions, the wear is distributed. The escapement-wheel 78 is arranged behind the paper-apron 79 and is connected by a shaft 82 to a pinion 80 gearing with a rack 80a on the carriage. The bearing for the shaft 82 consists of a sleeve 81 threaded in the bracket 67 and provided with a rib forming a race for two sets of balls running on cones on the shaft. The anchor 70, Fig. 7, formed with teeth 85, 86 for alternate engagement with the escapementwheel, is provided with a slot 85<a> engaging a pivot 84. On operating the universal bail, the tooth 85 is released, and a spring 87 draws the anchor a slight distance to the right and thereby prevents the tooth 85 from re-engaging the same tooth of the escapement-wheel and arresting the feed when the carriage is not moved immediately by the spring drum. Space-key actions.-The space-bar 72 is secured to three levers 73, the middle lever being connected by a link 75, Fig. 2, to a lever 74, which is connected by a link 78 to a lever 77 arranged near the universal bail 61. A returning-spring 76 is arranged between the lever 74 and the middle lever 73.

Title: Improvements in guns and in projectiles for use therewith
IPC: F41A21/28
Filed: 1920-07-02
Abstract: 146,349. Maze, C. A. F., (known as Maze, D.). Aug. 26, 1918, [Convention date]. Ordnance design; muzzle-loading; hydraulic and pneumatic; chambers.-Consists in means in the form of a converging-diverging nozzle a' in the bore of the gun to ensure rapid expansion of the propelling-fluid, gas, vapour, or liquid, before it acts on the projectile, combined with means, such as lateral ports in the gun-barrel or the expansion chambers a<4> shown in Fig. 2 for permitting part of the gases, &c., to escape to the atmosphere before the projectile leaves the gun. The projectile may be of ordinary construction, or it may have a hallow funnel-shaped base b<6> with lateral ports b<60> as shown in Fig. 2. When an ordinary projectile is used, it is inserted from the muzzle end of the gun and rests against a shoulder in the bore in front of the nozzle. In such case, rearwardly-directed gas-escape ports, which also serve to neutralize recoil, are formed through the walls of the gun in rear of the projectile seat and other similar ports may be provided nearer to the muzzle. In the form shown in Fig. 2, a series of expansion chambers a<4> is formed in the walls of the barrel extension a<3>. The area of the base of the projectile is approximately double that of the nozzle outlet. The projectile b is supported by two spaced bands b<4>, b<5>, and may be rotated by the action of the gases upon inclined ribs disposed between the bands as the gases escape past the projectile into the chambers a<4> and thence to the muzzle. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a gun adapted to fire the tubular winged-tail externally-fitting projectiles described in Specification 140,124, [Class 9 (i), Ammunition, &c.]. This gun is also provided with a convergent-divergent expansion nozzle in the bore. This subject-matter does not appear in the Specification as accepted.

Abstract: 1517772 Feeding articles to hoppers; tipping apparatus MOLINS Ltd 30 April 1976 [2 May 1975] 18395/75 Headings B8S and B8E Apparatus for feeding rod-like articles, e.g. cigarettes, to a magazine (26), Fig. 2 (not shown), comprises a rotatable frame member 22 which has two cigarette tray carriers 20a, b, the arrangement being such that when one of the tray carriers is inverted and located above the magazine (26) for discharge of cigarettes into the magazine the other tray carrier is non- inverted and is in a position to receive a full tray of cigarettes for subsequent discharge into the magazine (26), and during rotation of the frame member 22 an axis about which it rotates is lifted in order to prevent a tray carrier from colliding with the magazine (26). In the arrangement of Fig. 3 the apparatus comprises a pair of parallel side plates 32 (only one shown) between which the frame member 22 is located, and the frame 22 is attached to an arm 46 associated with each side plate 32, each arm 46 having a pair of rollers 48, 50 mounted thereon and being connected to a gear wheel 42 which is rotatable about an axis 24 on a respective link 40 rotatably mounted on the axis of a gear wheel 38, a further gear wheel 44 being in mesh with the gearwheels 42, 38. Each side plate 32 is provided with a key-hole shaped slot 52 and in the solid line position shown in Fig. 3 each arm 46 is located in the lower portion of its slot 52, the roller 50 being lowermost, and when a motordriven gear 34 is operated each gear wheel 38 tends to rotate clockwise whereby each gear wheel 42 and arm 46 also tends to rotate clockwise but is prevented from doing so by the lower portion of the slot, so that the links 40 are caused to rise about the axis of gear wheel 38 until each arm 46 enters the upper circular portion of its associated slot 52 whereupon the gear wheels 42 and arms 46 rotate clockwise (and thus the frame member 22 also rotates about the axis 24) until each roller 48 enters the lower portion of its slot 52 at which time the arms 46 drop into the lower portions of the slots. The frame member 22 has then been rotated through 180 degrees so that the positions of the tray carriers have been reversed. In the embodiment of Fig. 4 (not shown) an arm (146) is attached to the frame member (122), the arm (146) having rollers (148, 150) at its ends which move in a slot (152) formed in a side plate (132). In order to invert the frame member (122) the arm (146) is rotated upwards about the axis of roller (150) and when roller (148) is located in the upper slot apex roller (150) is moved along the lower surface of slot (152) and then the arm (146) is again rotated downwardly about roller (150). Movement of arm (146) can be effected manually.
