Title: Arc-welding mask
IPC: A61F9/06
Filed: 1953-02-17
Abstract: 725,166. Welders masks. PERROT, P. G. J. Feb. 17, 1953 [Feb. 26, 1952], No. 4395/53. Class 97 (1). A welder's mask comprises a filter screen carried in a slide movable in a slideway in the mask to cover or uncover a window thereon and moved by a mechanism controlled by a lever pivotally mounted on a support capable of being fixed to the electrode-carrying sleeve, the mechanism comprising two levers operatively connected to the slide and rotatably mounted on the mask, the levers forming an X-shaped arrangement that resilient means tends to open, and one of the levers being connected to the control lever by a Bowden or like cable. As shown the mask, fitted to the head by a band 7, comprises a plate 1 having an aperture 9 covered by a transparent window 10, and a plate 13 having guides 13a in which is vertically slidable a frame 14 bearing a filter screen 15. Movement of the frame 14 is effected by levers 19, 20 pivoted respectively at 21 and 22 to the plate 13 and connected by a link 24, the levers 19, 20 having pins 17, 18 sliding in a slot 16 in the frame 14. Pivoting of the lever 20 to raise the screen is effected by a Bowden cable 28 attached at 26 to the lever 20 and manually operated by a lever 37 fixed to the sleeve 40 of the electrode 49. Also controlled by the lever 37 is a microswitch 43 which, in the release position, opens the circuit between leads 46, 47 connected via terminals 55 and 56 to the power supply. When the lever 37 is operated to move the filter 15 before the eyes, the circuit through the microswitch 43 is closed whereby a solenoid 57 is energized to close the circuit through the primary of a transformer 60, the secondary of which is connected to the electrode 49, and a clamp 63 connected to earth. Thus the electrode circuit is made only when the filter screen is in position.

Abstract: 251,052. Merz & McLellan, and Weeks, E. G. Feb. 25, 1925. Discharging. - Coke is extracted from a vertical retort by a series of discharge devices which are operated in such a manner that there are produced, within the charge, vertical zones in which periods of quiescence alternate with periods of movement through the retort. As shown, the discharge devices comprise oscillatory pocketted rollers 35 which may be constructed according to Specification 251,051 and which are all operated at the same time or some operated while the others remain stationary. Separate driving gear is provided for each roller 35 and curved partitions 36 are fitted between adjacent rollers. To each roller shaft 10 is secured a toothed wheel 11 on which is fitted a spring strip 33 adapted to reverse the direction of rotation by throwing over a double-arm snap-over pawl 14 ca.rried between a pair of driving arms 12 which are pivoted on the shaft 10 and oscillated by a mechanically, hydraulically, or electrically actuated rod 20. The motion of the rod 20 is communicated to the arms 12 through a clutch device which is automatically disengaged should any jamming of the roller 35 occur and which can be declutched by the hand-lever 28 when it is desired to stop the roller. The lever 28 is pivoted at 29 and secured at 30 to a pin 25 which is normally held, by the adjustable spring 27, in engagement with a notch 24 in a member 23 connecting arms 21, these latter being pivoted at 22 to the main arms 12 and having a second spacing member serving as a pivot for the driving rod 20. When hydraulic driving apparatus is used, the clutch device may be dispensed with, each hydraulic cylinder being so gauged as to exert only sufficient pressure to drive the roller under normal conditions.

Abstract: 608,276. Mixing-machines. WEBB, W. P. Feb. 19, 1946, No. 5161. [Class 86] In a concrete &c. mixer sand and aggregate are placed in compartments arranged in line end to end, and fed by a helical conveyor extending through both compartments, the lengths of the compartments and the pitch of the parts of the conveyor each being such as will deliver a mixture of known proportions, the latter being variable by adjustable plates slidable upon the end walls of the compartments. The materials are fed to a stationary mixing trough. Sand and aggregate are fed to a stationary mixing trough 20, Fig. 1, by a helical conveyer mounted on a shaft 24 having a part 44 in the aggregate compartment 14 of smaller pitch than a part 45 in the sand compartment 15, the lengths of the compartments and the pitch of the parts being such that a mixture of known proportions will be delivered. These proportions are variable by adjustable plates 66, 67. Cement is supplied from a compartment 51 by a helical conveyor 64 connected through dogs 84, 85 to a shaft 25 driven by a belt and pulley drive from the shaft 24. The compartment 51 is mounted for adjustment parallel to the length of the mixing chamber, a connecting shaft being interposed if necessary between the dogs 84, 85. Water is fed through a perforated tube 61 extending across the width of the chamber 20 and supplied from a tank 80 through a manually adjustable valve provided with a scale indicating the volume of flow, and through a cut-off valve 83. Fig. 4. The latter is operable by linked levers 58, 59, 60 connecting with the rotary operating rod 70 of a clutch 28 through which the shaft 24 is driven from a motor 26, so that the water supply is cut off when the drive to the conveyors is interrupted. Helical mixing paddles 46 are mounted on the shaft 24 within the chamber 20, and additional paddles 48 having blades of V section may be bolted to the shaft between the paddles 46. The conveyor 64 and the shaft 24 are both removable bodily from the forward end of the machine. A wire mesh screen 69 protects the exposed portion of the mixing trough 20.
