Title: A new or improved machine for doubling tin-plates or sheets
IPC: B21D5/04
Filed: 1922-04-12
Abstract: 198,719. Davies, G. M., Davies, W., and Edwards, F. F. April 12, 1922. Angular bending; shearing.- In a machine for doubling and shearing tin-plates or sheets of the kind in which the sheet is held by side and end stops and doubled by a table having a leaf mounted on a rock shaft, the sheet is held between a longitudinally adjustable end stop, a spring-controlled off-side stop and a spring-controlled depressible and adjustable near-side stop, and the leaf is mounted on spring-controlled rising and falling hinges and is rocked by arms through a swing- ing frame which is connected to the reciprocatory part of a driving member connected to its shaft by a pedal-operated clutch. The table top of the machine is on a level with the flooring plates of the rolling mill and consists of a fixed plate a<1> and a leaf a<2> pivoted on spring-controlled rising and falling hinges a<3>. The leal is connected by links c<3> to arms c<2> on a shaft c which is rocked by a suspended U- shaped frame d connected by a rod d' to the reciprocatory part of the driving-member. The work sheet j is placed on the table against an adjustable end stop i and against an off-side stop g, which is normally pressed forward by a spring. On slightly depressing a pedal e, a lever k<3> pivoted to a casing h' is raised by a linkage k<1>, k so as to bring its extension k<4> into engagement with an inclined extension m on a lever m<1> and so remove a spring-pressed pawl m<3> from contact with a fixed rack m<4> to allow a slotted rod h<4> on which the pawl is carried to be pressed upward by its spring. A finger h<2> forming the near-side stop, which is normally held in the retracted position by cam plates h<3> on the rod engaging cam surfaces h<5> on the finger, is thus released and pressed forward, by its spring to engage and hold the edge of the work. This stop is adjusted by a screw h<7>. The pedal is then fully depressed and through a rod e<1> puts in a one revolution clutch on the driving shaft so that the leaf a<2> is moved on its pivots so as to double the sheet, the hinged end of the leaf rising to accommodate itself to the thickness of the sheet. Towards the end of the forward movement, the stop g is withdrawn by a wiper c<4> on the shaft c engaging a lever g<2> pivotally connected to the stop rods g<1>. At the same time the leaf a<2> depresses the rod h<4> until it is flush with the table top and is looked by its pawl m<3>, the stop h<2> being thus withdrawn from contact with the sheet. At the end of the backward movement of the leaf the clutch is disengaged and the sheet then removed and placed with its raw edges between the blades of a shearing device. The pedal is then again fully depressed to operate the shears. The movable blade b is pivoted and is actuated by a crank f on the shaft c through a link f<1>.

Title: Improvements in arc welding electrodes
IPC: B23K35/02
Filed: 1931-01-05
Abstract: 370,897. Uniting by fusion. GROVES, W. W., 30, Southampton Buildings, London. -(E. M. F. Electric Co. Proprietary, Ltd. ;. 1059, Rathdown Street, North Carlton, Victoria, Australia.) Jan. 5, 1931, No. 369. [Class 83 (iv).] An arc welding electrode consists of a metallic core coated with an adhesive such as sodium silicate to which is applied a layer of asbestos or other fibrous fluxing material in a loose or free state. The asbestos may be applied by mechanical means or by an air blast. Two or more successive layers may be applied by successively coating with adhesive and loose fibres. The fibres are electrified so as to repel each other when applied to the core and thus obtain uniform spacing apart thereof. Electrification may be effected by connecting the core to a source of electric energy, preferably by contact rollers, so as to electrify the fibres by electrostatic induction, or the fibres may be electrified by mechanically agitating them or frictionally rubbing them together or by providing electrified wires in the chamber containing the fibres, or in the conduit through which they are delivered on to the core. The fibre-covered electrode is then passed through means such as revolving brushes to discharge electrically the fibres 4 and to wrap them round the core 1 helically as shown. The electrode may be then passed through a nozzle for applying an external coating 5 of flux to produce an electrode which by reason of the resilient layer of fibre may be bent without cracking or detaching of the flux coating, which is also spaced from the core to ensure better flowing of the metal thereof.

Title: Hydraulic control valve with flow sensitive unlatching mechanism
IPC: F16K35/00
Filed: 1971-01-05
Abstract: 1339914 Valves INTERNATIONAL HARVESTER CO 5 Jan 1971 [5 Jan 1970] 451/71 Heading F2V [Also in Divisions G2-G3] Rightward movement of spool 11 to the Raise position closes open-centre passage 28, 29, connects supply passage 21 to work port 23 and connects work port 22 to drain 24, and latch balls 95 are urged into groove 86 by ball 97 to retain the spool in position. Fluid flowing to the port 23 shifts pilot valve sleeve 110 leftwards against spring 111 to disconnect passages 115 from passage 62 leading to the spool interior. When the motor piston 39 reaches the top of its stroke, the flow through port 23 ceases and sleeve 110 returns to connect passages 115, 62, thereby pressurizing chamber 60a in the spool to cause piston 94, 101 to de-latch the spool which is then returned to neutral by spring 92. Leftward movement of the spool to the Lower position closes the open-centre passage, connects port 22 to supply passage 21 and connects port 23 to drain 24, and latch balls 95 are this time urged into groove 87. Land 112 of the sleeve 110 is moved into bore 52 but the flow urges it against spring 111 to a position allowing free flow from port 23 to drain. Fluid entering the spool interior via 61 is allowed to drain via 63 until the piston 39 reaches the bottom of its stroke, at which time the flow from port 23 ceases and the sleeve shifts rightwards to close 63. Pressure then builds up in chamber 60a to release the latch as before and allow spring 92 to re-centre the spool. The balls 95 engage groove 88 in the Float position.

Title: Apparatus for cleaning components with flow passages therethrough
IPC: A01J7/02
Filed: 1959-01-07
Abstract: 871,201. Cleaning components of milking machines. SEPARATOR A.B. Jan. 7, 1959 [Jan. 11, 1958], No. 623/59. Class 138(1). [Also in Group XXVIII] Apparatus for cleaning milking-machine components having flow passages therethrough, and having means for passing cleaning liquid to and fro through the flow passages, comprises a container 1 divided into compartments 14, 15 by a flexible diaphragm 13, the compartment 14 being connected through a cock 9 to a pipe 8 leading to a vacuum pump (not shown), and the compartment 15 being connected by nipples 7 to the milk tubes 6 connecting with the teat cups and other components 5 of the milking machine immersed in cleaning liquid in an open container such as a sink 2. When the cock 9 is open the vacuum applied through pipes 8, 19 and an opening 20 raises the diaphragm 13, to the position shown, thus drawing cleaning liquid through components 5 and the pipes 6 into the compartment 15, a valve 10 in a return line 11 being closed by the applied suction. The upward movement of the diaphragm 13 raises a valve member 17 to close the opening 20, and also lifts a perforated sleeve 18 to open a valve 22 against the action of a spring 23, so that air is admitted to the compartment 14. The diaphragm 13 is then pressed downwardly by a spring 28 to discharge cleaning liquid through the tubes 6 and also through the return pipe 11 via the valve 10 opened by the pressure now applied thereto. As the diaphragm 13 nears its lowermost position the valve member 17, which is connected thereto by a nylon thread 16, is moved away from the opening 20, and the sleeve 18 is carried downwardly to allow the spring 23 to close the valve 22. Vacuum is thus again applied to the compartment 14 and the cycle repeated. If desired the spring 28 may be replaced by a weight, or the valve 22 may admit air at super atmospheric pressure, whereby the spring 28 and the weight become unnecessary. The invention may also be applied to the cleaning of other articles having flow passages therethrough.
