Title: Improvements in separable slider-operated fasteners
IPC: A44B19/38
Filed: 1928-03-16
Abstract: 287,148. Lightning Fasteners, Ltd., (Assignees of Sundback, G.). March 16, 1927, [Convention date]. Sliding-clasp fasten ings.-Relates to means for detachably connect ing at one end the stringer 10, 11 carrying the interlocking elements 12, the slider 13 being retained or one of the stringers when the latter are separated, the arrangement being such that the stringers are reconnected in proper relationship for the slider to operate. The connecting device carried by stringer 10 comprises a member 14 permanently clamped to the edge of the stringer immediately below the lowermost element 12 thereon, and having pivoted thereto at 17 a member 15. Member 15 comprises two side plates embracing member 14 and connected together at their upper ends by a cross-bar 20. Members 14, 15 may be pivoted to a yoke 16 with a ring 24 to facilitate holding by hand, and are of such size that the slider can move on to them, moving them apart to the position shown, bar 20 being then exposed above the top edge of the slider. Connected to a stringer 11 immediately below lowermost element 12 thereon is a cooperating connecting device 21, cut away at 34 to accommodate lowermost element 12 on stringer 10 in the fastened position and having a hook 23 enagaging bar 20, and detachable therefrom by movement of stringer 11 towards stringer 10. In the postion of slider shown, hook 23 together with stringer 11 can be connected or disconnected but when the slider has been moved upwards to interlock the elements 12, device 21 abuts against the part 19 of member 14 so that disconnection is prevented. In another form Fig. 6, stringer 16 has connected thereto by jaws 27 a member 25 with jaws 28 between which the edge of the stringer 11 can be passed, and stringer 11 has connected thereto a stop member 26. With the slider 13 in its extreme position arrested by jaws 28 as shown, stringer 11 may be removed endlong from jaws 28, but with the slider moved upwards and elements 12 interlocked removal is prevented. Unless member 26 is in correct position abutting against jaws 28 it fouls the element 12 on stringer 10 and prevents movement of the slider. The end portions of the stringers below elements 12 may be stiffened by shallac, collodion, &c.

Abstract: 418,208. Feed - -water regulators. DIGHT, S. R., H.M. Gunboat Yard, Haslar, Gosport, Hampshire. March 21, 1933, No. 8493. [Class 135.] In apparatus for regulating a supply of liquid for maintaining a constant level in a container, a feedvalve is subjected in one direction to the feed pressure and the container pressure and in the opposite direction to a pressure which varies up to the feed pressure. Fig. 1 shows an apparatus of the type wherein a valve a controls the passage of the feedwater from supply at d to the container connected at d<1>, feed pressure building up under the leaky piston b when a throttle valve at m is closed by the falling of float k. Leakage passages o, o<1> may be provided in the piston b co-operating with a throttle valve q as in Specification 376,264. The valve a is rendered sensitive and smooth in action by leading feed pressure to a portion of its upper face by a passage a<3>, said portion acting as a piston (or cylinder) co-operating with a cylinder c<2> (or piston). The throttle valve l is shown in Fig. 2, the tube e being connected above the bush p, and the tube n connected below the bush p leading the leakage water directly to the boiler. The leakage water may also pass to the float-chamber by apertures l<4> and grooves in the spindle of the valve l. A spindle s may be screwed down to close the valve a and passage a<3>. A non-return valve f protects the valve a from operation by the boiler pressure should the feed-pressure fail. Specification 285,280, [Class 135], also is referred to.

Filed: 1918-05-22
Abstract: 118,595. Domestic Engineering Co., (Assignees of Midgley, T.). July 30, 1917, [Convention date]. Specific - grvaity estimating-apparatus for indicating the charge of an electric battery consists of a celluloid or like member 23 totally submerged in the electrolyte and pivoted by means of a knife-edge 26 on a stationary support 25 fixed to the cell or to one of the electrode plates. The support 25 acts as the indicator for a scale 28 on the portion 23, which may be graduated to indicate specific gravity, charge, or other quantity. Secured to one corner of the member 23 is a weight 29 formed of a number of rubber pieces graded to a definite specific gravity. This is preferably so arranged that the hydrometer assumes a vertical position when the specific gravity of the electrolyte is the same as that of the weight 29. The member 23 is formed with a counterweight 30, and to prevent adherence of gas bubbles when it is made of celluloid, it is cleaned before use with a mixture of powdered pumice and sodium cyanide and rinsed in distilled water.

Abstract: 867,913. Jigs. MILNES Ltd., HENRY. June 12, 1958 [March 15, 1957], No. 8603/57. Class 83 (3). In a method of producing deep holes by drilling from opposite faces of the work, alignment is obtained by means of a rod 7 set relatively to the axis of a toolhead spindle 8 and by means of stops 11, 16, set relatively to a dial indicator 10, the distance between either stop and the indicator being measured by gauge-bars 12, 12a inserted therebetween. In use, the rod 7 is positioned relatively to the work, on an angularly adjustable table 3 of a horizontal boring machine. The rod is aligned with the spindle 8 and the stop 11, on a main table 4 carrying the table 3, is set to zero against the indicator 10. The table is moved a distance A so that the axis 13 of the hole coincides with the axis of the spindle 8 and a first blind hole is drilled by boring-bar 15. On retraction of bar 15, the table is moved to a distance set by gauge-bar 12a so that the second hole may be blind drilled. The bar 15 is again retracted and the table 3 rotated through 180 degrees, the bar 7 being set to the axis of the spindle 8 and the stop 16 being set to zero against the indicator 10. The table 4 is moved in the opposite direction, the distance A being set by the gaugebar 12 and, the axis 13 of the hole being aligned with the axis of spindle 8, the first hole is completely drilled. The bar 13 is again retracted and the table moved to the position shown in Fig. 8, whereupon the second hole is completely drilled. In an embodiment for obtaining alignment in a vertical plane, a gauge-bar 12b, Fig. 10, is inserted between a stop 11a on a movable knee 2a and an indicator gauge 10a. Vernier scales may be used to register the distance moved by the table 4.

Abstract: 780,191. Valves. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. March 25, 1955 [March 26, 1954], No. 8892/54. Class 135. In a control device for a fluid system having a number of fluid supplies and for each supply a metering orifice 19, 20 defined by two pairs of parallel boundary walls, a first control means, such as a shaft 8, for varying the orifice width by effecting relative movement between the walls of one pair towards or away from each other without varying the orifice length, and a second control means, for example, a handwheel 12, for varying the orifice length by effecting relative movement between the walls of the other pair towards or away from each other without varying the orifice width, the first or second control means for the respective supplies are interconnected for simultaneous operation. Fuel enters a liner 6 via an annulus 16 and ports 18 and leaves by way of the orifice comprising ports 19, 20 in a piston 9 and the liner 6, respectively, the orifice flow area being adjustable by rotating the liner through its shaft 8 and/or sliding the piston 9 in the liner through the handwheel 12. The shafts 8 of a number of devices are interconnected by a rod, and the piston position is indicated by a pin 14 located in a slot 15 in the housing, which arrangement also prevents rotation of the piston during its translation. The ports 19, 20 may have the shape of a rectangle or parallelogram for example. In a modification, Fig. 3 (not shown), the liner is not rotatable, the degree of throttling of the metering orifice being effected by rotating and/or sliding the piston. Indication of the piston position is given by a shroud on the handwheel. In another modification, Fig. 5 (not shown), the liner is again incapable of rotation but each valve has one inlet and two outlets, the sleeve and piston embodying two metering orifices each co-operating with a separate one of the outlets; the orifices are so disposed that the flow area of one diminishes as the other increases.
