Title: Improvements in and relating to electric switches
IPC: H01H33/98
Filed: 1921-11-16
Abstract: 193,136. British Thomson - Houston Co., Ltd., (General Electric Co.). Nov. 16. 1921. Oil switches of the kind in which the high pressure of oil produced in an explosion chamber is employed to extinguish the arc, are arranged so that the circuit is broken in two stages, the pressure produced at the first break being utilized to extinguish the arc at the subsequent and final break. In the form shown in Fig. 1, a subsidiary contact rod 25 engages a fixed contact 14 within an explosion chamber supported from the lid of the oil tank. The lower end of the contact rod 25 carries a contact 24 with which the contact rod 15 engages. The rod 15 is carried by the operating member 18 and the circuit between the external terminals 11 is through the contacts 14, 25, 24, 15, bridging-bar 17 and the similar contacts on the other half of the switch, all in series. When the operating rod moves downwards, the rod 25 moves downwards with the rod 15 under the action of the spring 29. Circuit is 'thereby broken between the contacts 14, 25, and, immediately afterwards, the contact 24 reaches a series of insulating plates 23 and its movement is arrested so that further movement separates the second contacts 24, 15. The second arc is extinguished by a cool flow of oil passing between the plates 23 and resulting from the pressure produced by the first arc. The rod 15 may be tubular, open at its upper end and at a point near the member 17 so that oil may be ejected across the arc and through the tube. In a modified construction shown in Fig. 2, the second contact 34 is fixed and forms part of a hollow electrode 31 mounted centrally in the explosion chamber. When the rod 15 leaves the upper contact and enters the electrode, the arc is transferred thereto, and, when the rod leaves the electrode, a ball 36 carries the orifice. When, finally, the contact rod leaves the second contact, the arc is extinguished by the pressure of oil produced by the first arc escaping through the passage 38. In the upper part of the explosion chamber a hood 40 is arranged to retain a portion of the gases to act as a cushion and prevent undue shock. In a modification of the arrangement shown in Fig. 1, the lower contact is arranged within a bushing and the lower contact rod controls oil passages between the explosion chamber and the tanks to direct, the oil at the right moment across the arc.

Title: Improvements in massage machines
IPC: A61H7/00
Filed: 1934-10-26
Abstract: 446,280. Scalp-massage apparatus. GRO-FLEX CORPORATION, 141, South Sherman Drive, Indianapolis, Indiana, U.S.A.- (Assignees of Hamblin, R. H. ; 3157, North Delaware Street, Indianapolis, Indiana, U.S.A.) Oct. 26, 1934, No. 30687. Convention date, Oct. 28, 1933. [Class 81 (ii)] A scalp-massage device comprises a fixed support having a hub on which a frame rotates, the said frame having a bearing, in which the applicator is journalled, the axis of which is oblique to the axis of rotation of the frame, and a member connecting the hub and the applicator which permits rocking of the applicator while preventing its rotation relative to the support. In the arrangement shown, the moving parts are arranged inside a hollow supporting casing 5. The frame or drum member 36 rotates on a fixed hub 27 supported from the casing, and is rotated by motor 19 through gears coacting with internal gear 37 secured to the upper side of the member 36. The lower part of this member consists of a transverse wall 41 which is disposed in a plane oblique to the axis of rotation of member 36. The applicator 6, preferably of soft rubber, is attached to a hub 46 which is mounted in a suitable ball-bearing in an opening 42 eccentrically disposed in the lower wall 41 of the member 36. Rotation of the applicator is prevented by a link member connecting the hubs 27 and 46. Each of these hubs have axial recesses 60 and 61 which form housings for a pair of gimbal joints 62 and 63 which have studs 70 and 72 of elliptical cross-section projecting outwardly. These studs are connected by a sleeve, thus rendering the studs non-rotatable with respect to each other, and permitting slight variations in the distance between the centres of the gimbal joints as the parts rotate. The drum member has a downward extension 74 terminating in an irregularly shaped flange 75 lying in a plane perpendicular to the axis of rotation of the member 36. A complementary flange 76 in the outer casing shuts off the rotating parts from the outside of the device. Specification 443,711 is referred to.

Abstract: 1,248,141. Staking electrical terminals; shearing. AMP Inc. 19 May, 1970 [17 June, 1969], No. 30724/69. Headings B3A and B3W. Apparatus for staking terminals from a strip 111a, 111b of such terminals to a board, comprises a staker 97 movable towards and away from an anvil 45 having a holder for a leading terminal, feed means for feeding the strip past a shear block 33 to the terminal holder, the anvil 45 being adjacent the shear block 33 and movable to move the holder laterally of the shear block between a first position in alignment with the strip feed path and a second position in alignment with the staker 97, movement of the holder in one direction between the positions shearing a leading terminal from a strip and in the other direction advancing the staker towards the anvil. A support board (210), Figs. 4, 5 (not shown), is placed on a plate 70 and the required staking holes (212) are aligned with the staker by engaging a finger 74 in a corresponding groove 75 of a comb 76 by sliding and pivoting the plate about a shaft 73. This pivotal movement also engages arms 88, 89 of microswitches 86, 87 and locates arms (113), (114), of a terminal pin (110) in the holes of the support board (210), Figs. 1, 4 (not shown). The switch 86 controls the supply of air to a unit 91, which actuates the staker and the switch 87 controls a solenoid-operated change-over valve supplying air to a unit 56 via a switch 69. The unit 91 is actuated to drive the staker 97 downwardly along with a tubular member 103 fitted with a rubber pad 106. The pad engages the surface of the support board, whereupon downward movement of the member 103 ceases, and the staker movement continues until the terminal pin is staked to the board, the pin being held in a channel 50 in the anvil 45. Terminal feed.-A channel 51 is aligned with the channel 25 which contains the strip 111a and a pin 57 engages a microswitch 63 controlling air flow to a unit 17 as the unit 56 is advanced, thereby engaging the leading pin of the strip 111a with a feed finger 22 and advancing it into the channel 51 and retracting a unit 16. As the unit 91 retracts, a striker plate 68 actuates the switch 69 and pivoting of the support plate. 70, as the support board is removed, disengages the plate from the arms 88, 89, thereby activating the switch 69 to retract the unit 56. The unit 56 moves a lever 55 to the right pivoting: the anvil 49 anti-clockwise about a pin 43 to shear the leading terminal in co-operation with the shear block 33 from the strip and align it with the staker. At the same time the channel 50 is aligned with the channel 25 containing the strip 111b in readiness for the next operating cycle.

Title: Improved fire engine
IPC: A62C5/00
Filed: 1926-12-04
Abstract: 283,316. Martin, W. E. Dec. 4, 1926. Fire-engines; fire-extinguishing by foam; chemicals.-A fire engine is adapted to deliver, as required, either water, or foam formed by mixing separate solution streams produced by adding dry chemical to two supplies of water. As shown in Fig. 1, a water supply pipe a provided with a pressure reducing and regulating valve d is divided into two branches. Each water branch passes by an adjustable valve e to a mixing chamber h above which is a hopper i. The two hoppers are charged respectively with dry alum, liquorice, and saponin and with dry sodium bicarbonate, and each hopper has a rotary feeder j driven by a belt w, and a controlling slide k adjustable by a rack and pinion l and lever m. The falling chemicals are taken up by their respective water sprays from the valves e and may pass into tanks n provided with baffles o. The solutions are taken from the tanks or direct from the mixing chambers h by a duplex pump q, for example of the kind described in Specification 215,181, [Class 110 (ii), Rotary engines &c.]. and delivered separately to two pipes r which merge into a single mixing and foam delivery pipe t. Pipes v controlled by spring-loaded valves u return solution to the tanks if the pressure in the pipes r becomes too high. If the slides k are closed and the valves e fully opened, water alone will be de livered to the pipe t by the pump q. In a modification, Figs. 4 and 5, water to be delivered alone is taken from a separate source. The duplex pump q, Fig. 4, has associated with it a manifold comprising a body or valve chamber z having an opening 1 for connection to a watersupplying pipe. In the body are openings 2 controlled by valves, not shown, and connected to the pipes p from the respective, solution tanks n or mixing chambers. The body also has an opening to the pump q divided into two parts by a partition 6 in which is an opening controlled by a valve 8. When foam is to be delivered, the opening 1 is closed by a cap 11, the valve 8 is closed, and the inlets 2 are opened. The pump q then draws in the separate solutions and passes them to a second manifold, whence they pass by valve-controlled outlets and pipes r to twin hose pipes x and a mixing and delivery pipe t. If water is to be delivered, the opening 1 is connected to a water supply, the inlets 2 are closed the valve 8 is opened, and the pump q delivers water alone to the manifold 12 whence it passes by outlets 13 controlled by valves 14 to separate delivery lines. The manifold body z has an opening 10 for connection to an air vessel to assist the suction of the pump, if necessary. In this con. struction, the feed rollers in the hoppers are operated by bevel gearing. In another modification (Figs. 7 and 8, not shown), the hoppers i are controlled by cone valves which are rotated to feed the chemicals and are also linked to the water valves e so as to be operated in unison with them.
