Title: Improvements in, or Additions to, Beer-engines and Analogous Appliances for Pumping-up Liquids
Inventor: LAWDEN JOSEPH
Filed: 1903-02-23
Granted: 1903-12-17
Abstract: 4192. Lawden, J., Poole, F. S., and Newey, H. R. Feb. 23. Beer, raising and drawing - off. - Means for preventing the dripping of liquid from the nozzles of beer-engines due to the displacement of the liquid by the entry of the bucket - rod into the pump cylinder in its return stroke &c. comprise (1) a compensating-chamber applied to the pump cylinder, and (2) the construction of a pump in which the pump rod has no displacing effect during its return stroke. In the first arrangement, Fig. 1, the pump cylinder a is connected by a side passage c<1> to the compensator d, consisting of a body part d<1> fixed to the side passage and to the delivery pipe c, with a part d<2> adapted to telescope over the fixed part, a liquidtight joint being effected by a packed stuffing-box connection f, f<1>. The bucket-rod b is jointed to a grooved block e<3>, in which slides a radius arm e carrying a link e<1>, which, by its attachment to the lower part d', communicates motion thereto from the bucket-rod. During the down-stroke of the rod, the capacity of the chamber d is increased, said chamber receiving the liquid expelled by the rod and indrawn from the outlet pipe, and, conversely, in making the return stroke, liquid is expelled from the chamber d with the contents of the cylinder into the discharge pipe c. In a modification, the telescopic chamber d is replaced by a. bag of flexible material (gusseted or otherwise), with a rigid base having the transmission link e<1> pivoted thereto, and provided with a pin fitting into a slot in the supporting-framework ; or the variation in the capacity of the bag may be obtained by squeezing the flexible sides laterally between pressure plates, to which motion is imparted by the bucket-rod. Fig. 8 represents a pump in which no liquid is displaced by the rod in its return stroke. The bucket-rod b passes through the stuffing-box a' placed at the end of the pump cylinder a opposite to the discharge pipe c, and is either operated by a slide b<1> working in guides b<2> on the sides of said cylinder, or worked by a system of crossheads and links. The Provisional Specification describes a method of automatically closing the pump outlet to prevent the liquid in the cylinder &c. from coming into contact with the air when the bucket is at the bottom of its stroke. An additional valve is provided at the outlet branch of the pump, with its axis at right-angles thereto, and consists of a seating, having a taper plug fitted on a rod which derives its motion from the bucket-rod and passes axially through the delivery pipe ; in the case of a pump provided with a compensating-chamber, the. valve-rod is continued down to the movable part of the chamber. The valve opens during the delivery stroke of the pump, and gradually closes in the return stroke.

Title: Improvements in Machines for Wrapping Chocolates and the like in Tin Foil, or other Suitable Material.
Filed: 1904-04-20
Granted: 1905-04-20
Abstract: 9043. Keiller & Son, J., Boyd, W., and Robinson, V. April 20. Parcelling confectionery.-In a power or band machine for wrapping-up chocolates and the like in tin foil &c., the wrapper, with the chocolate above it, is brought over an annular brush or over a diaphragm of indiarubber having a central hole or cross-slit in it; the chocolate and wrapper are pushed partly through the centre of the annular brush by a descending plunger, the plunger is then withdrawn to allow the fibres of the brush to close the wrapper round the chocolate, and the plunger is again lowered to expel the chocolate. In a machine shown in Fig. 2, tin foil is intermittently drawn from the roll 17 by the table 22, which is reciprocated by the lever 23, operated by the cam 24 on the main shaft 68, this shaft being connected to the belt pulley 69 by the friction clutch 67 governed by the pedal 66. The table 22 carries a gripping-spring 19 governed by the roller 20, which is alternately raised and lowered by the rocking lever 21 driven from the cam 33. The tin foil carried forwards by the table 22 is gripped by the grippers 28, 29, Figs. 2 and 5, which are adjustable to suit different widths of foil. The gripper 28 is prevented from descending by the ring 30, but the gripper 29 is lowered, against the action of the spring 31, by the cam 33 which pulls down the central support 36. The tin foil is severed by knives 18, 51, Figs. 2, 5, and 8, operated simultaneously by two pivoted levers 53, 54, which are driven from the cam 52 and are caused to turn at the same time by gear-wheels 55. The grippers 28, 29 and the frame 42 carrying the chocolates are now rotated through half a revolution by the cam 46, Figs. 2 and 4, driving the rack 47 which gears with the pinion 48 connected to the shaft 41 by a ratchet and pawl. The plunger 15, Fig. 9, which slides within the plunger 16, is now lowered by a pivoted lever connected to the rod 60, operated from the cam 58. After the plunger 15 has risen, the plungers 15, 16 are lowered together to expel the chocolate, the plunger 16 being operated from the cam 63. The machine may be adjusted to suit different lengths of foil by altering the position of the pin 27 and also altering the position of the slide 43, and thus moving the pin 40 engaging with a slot in the grippers 28, 29, which are capable of sliding in the frame 36. In a simplified apparatus operated by hand, the wrapper and chocolate are laid above the annular brush or diaphagm and the wrapper and chocolate are pushed through by hand or by a single plunger. The partly-wrapped chocolate is then finished by hand. In the Provisional Specification, it is stated that one end of -the wrapper may be folded over the chocolate before the plunger descends, and that the free ends of the wrapper may be folded over the chocolate by a series of horizontally-moving blades.

Title: Improvements in or relating to Driving, Free Wheel, Braking and Variable Speed Mechanism.
Inventor: BOULT ALFRED JULIUS
Filed: 1904-07-18
Granted: 1905-06-22
Abstract: 15,917. Boult, A. J., [Rockwell, A. F.]. July 18. Driving-mechanism ; brakes.-Relates to freewheel, back-pedalling brake and two-speed driving mechanism for cycles and like vehicles, the gear being changed by back-pedalling or by hand. Secured to the sprocket C', Fig. 1, is a screwthreaded sleeve C with which engage clutches E, G, adapted to engage the hub A for low-speed drive, and the sleeves F, D, respectively. The sleeve F carries planet-pinions F<2> which engage teeth D<4> on the brake-actuating sleeve D and internal teeth A' on the hub A. To retard the clutches E, G so that they move laterally when the sleeve C is rotated, a ring controller E'‹ and a split spring band G<7>, secured to the clutch G, are used. On forward rotation of the sprocket C', the clutch E engages the hub A, movement of the clutch G being prevented by a flange H<1> on a sliding tube H, carrying ratchet teeth H<2> pressed by the spring d<10> into contact with other teeth I<1> on a sleeve I, which has serrations I<4> engaging a fixed cone c<1> and also pawls I<3> engaging ratchet teeth on the sleeve C. For high speed, the rider back-pedals slightly, causing the teeth H<2>, I' to interlock, thus releasing the clutch G which on forward-pedalling engages the sleeve F, driving the hub through the gearing, the hub over-running the clutch E. On again back-pedalling slightly, the tube H is pressed back into position, and the low gear again comes into operation on forward-pedalling. On further backpedalling, the clutch G engages the sleeve D, which carries an arm D<7> attached to the free ends of brake rings d, the other ends of which are secured to an anchored adjusting-plate d<3> and are expanded against the hub. The speed gear may be operated by hand, as shown in Fig. 10, instead of by the pedals. In this case, the tube H carries balls h<1> instead of a flange, and is provided with screw threads h<4> which engage a sleeve H<2O> carrying exterior teeth H<5>, engaging with a toothed sector H<3> which is rotated by band through a lever H<4>, thus moving the tube H laterally. Modified brake mechanism, shown in Fig. 14, may be used. The teeth D' on the sleeve D, are extended and engage toothed pivoted sectors d<*> which press against the free ends of the rings d when the sleeve D is rotated. Backward rotation of the sectors and of the sleeve D is prevented by lugs d<7> on the rings d. The rings are held in place by lugs d<6> bearing against studs d<5*> in retaining-plates d<2>.
