Title: Improvements in or relating to pit props
IPC: E21D15/51
Filed: 1953-02-13
Abstract: 768,446. Hydraulic jacks. REYNOLDS, D. H. J. May 13, 1954 [Feb. 13, 1953], No. 4045/53. Class 78 (3). [Also in Group X] A pit prop, of the kind comprising two telescopic cylinders, one of which acts as a ram, a pump for feeding oil to a pressure chamber so as to expand the prop, and a valve or valves to permit the release of oil from the chamber, has the pump and valve or valves secured as a unit detachable from the ram cylinder. As shown, a pit prop comprises a cylinder 50, Fig. 1, and a ram 5, the ram being movable outwardly of the cylinder to expand the prop by introducing oil to a chamber 31 through a pipe 10. The pipe 10 is screwed to a cylindrical detachable head comprising a cap block 1, Figs. 3 and 4, and valve block 2. The cap block 1, Fig. 3, has a chamber 14 and a piston 26 engaged by a spring 27, such that oscillation of a rocker arm 29, by an external handle, causes oil within a reservoir in the ram 5, Figs. 1 and 3, to be drawn into the chamber 14 along a pipe 18, past a non-return valve 17, and be fed past a non-return valve 15 to the pipe 10 via a diametrical passage 11. A second shaft 33, Fig. 4, has a flat face 34 engaging a plunger 35 having a pin 36 which lifts a release valve 20 on rotation of the shaft 33, such that oil may return from the chamber 31 to the reservoir through the pipe 10, passages 11, 13, 19, 38 and 39. Should the prop be subjected to an axial load in excess of a value predetermined by the setting of a screw 48, a relief valve 22 is opened to return oil from the reservoir via passages 11, 13 and casing holes 47. During pumping of oil from the reservoir replacement air flows from the atmosphere through ducts 41, chamber 24, ducts 43, 42 and passage 23, the flow reversing when oil returns to the reservoir. A bleed valve piston 40 normally compresses, by its weight, a spring 25, such that the piston 40 is spaced from a seat 44, but when the prop is tilted from upright position the spring 25 forces the piston upwardly to prevent oil escaping through a hole in the seating. The cylinder 50, Fig. 1, and ram 5 are protected from damage by casings 54 and 56. In a modification, the shaft 33, Fig. 8 (not shown), is axially displaceable to operate the release valve 20, while the bleed valve is opened automatically by a reduction of air pressure within the reservoir or positively on actuation of the release valve.

Abstract: 847,862. Degasing metals. SCIENTIFIC RESEARCH INSTITUTE Ltd. Feb. 7, 1958 [Feb. 9, 1957], No. 4115/58. Class 72 Metal is vacuum degassed' by feeding at a controlled rate to a high vacuum degasification vessel from which it flows under gravity to a chamber at sub-atmospheric pressure, the rate of said flow being controlled by the relative pressures in the vessel and the chamber, and the static head of metal in the vessel. As shown, metal in receiver 2 flows through foraminated disc 4, the rate of flow being controlled by adjustable stoppers 5 in some of the jet holes. The depth of molten metal H is measured electrically by means of carbon bars 11. A stopper 12 is used initially to prevent communication between high vacuum vessel 1-1<SP>1</SP> and chamber 17-17<SP>1</SP>, which can contain a neutral, reducing or inert gas such as hydrogen, carbon dioxide or argon. When the desired head of metal H is reached, stopper 12 allows the metal to flow into chamber 17- 17<SP>1</SP> in which may be placed a ladle or mould. At least two chambers 17<SP>1</SP> may be used successively to reduce the delay between operations.

Title: Improvements in or relating to Marine Torches.
Inventor: HOLMES GWYLLYM ROBERT
IPC: B63B51/04
Filed: 1919-02-19
Abstract: 135,712. Holmes, G. R. Feb. 19, 1919. Phosphoretted hydrogen and like self-lighting signals.-A marine torch of the kind comprising separate chambers for generating acetylene, and a gas such as phosphoretted hydrogen which automatically ignites the acetylene, is c o n - structed with a common water inlet for supplying both chambers, and the gas outlet and water inlet openings, which are normally closed, are opened simultaneously by the launching of a life-preserver to which the torch is attached, or in any other manner. As shown in Fig. 1, the torch comprises a floating chamber 10 fitted with a weight 12 to keep the device vertical, and divided into an outer chamber 11 for containing carbide 22 and an inner chamber 13 for containing phosphide. The chamber 10 is fitted at the bottom with a screwed ring 16 perforated at 17 for passage of water to both chambers 11, 13. An inner perforated tube 14 telescopes into the perforation 17, and this perforation is normally sealed by a rod 28 fixed in position bv a lid 29, which is soldered to a flange 28<1> formed on the top of the casing 10, the lid 29 being fixed between a ring 31 and a collar 32 on the rod 28. The ring 16 of the torch is connected by a rope to a life-preserver, and the soldered joint is arranged to be broken by the launching of the preserver, although this joint normally permits the torch to be suspended by the ring 31. When the joint is broken, the opening 17 becomes unsealed, owing to the rod 28 remaining fixed. and water enters and passes by a tube 23 and perforations 24 to the carbide chamber, and by openings 25, 25<1> in the tube 14 to the phosphide chamber 13. The phosphoretted hydrogen generated burns at the mouth of the tube 14, which is arranged close to a burner 21 of the impinging type, through which the acetylene emerges. Alternatively, the acetylene may emerge from openings in the lip arranged concentrically around the tube 14.

A fastener for fastening gates, doors and the like members to gate posts, door jambs or the like members comprises a staple 4 or the equivalent associated with one of the members 5 and a tongue 1 connectable by a chain 8 or the like means to the other member the tongue being adapted to be passed through the staple or the equivalent and retained therein by retaining means which are manually operable to allow the tongue to be removed from the staple or the equivalent, the retaining means comprising a plurality of pawls 12, 13 pivoted to the tongue so as to be movable by hand to unstable positions which will allow removal of the tongue from the staple or the equivalent and movable by gravity from said unstable positions to a plurality of stable divergent positions which prevent such removal, stop means 16 being provided in the tongue to prevent the pawls from moving to positions in which the pawls point in the same direction. As shown two pawls are provided and these are pivoted to the tongue by a common pin 10. The pawls are prevented from falling too far by engaging surfaces 14 on the tongue. The stop means 16 is a pin joining the two limbs of the tongue which is of U-shape; it thus prevents both pawls falling in the same direction. The tongue is connected to the chain or the like by means of a projection 6 which is welded to the tongue. The tongue is withdrawn from the staple by moving the pawls so that they are aligned with the tongue. In a modification the pawls can be connected to the tongue by means of separate pivot pins.

IPC: B66D1/20
Filed: 1921-02-05
Abstract: 177,330. Klooker, P. J. Feb. 5, 1921. Winches; brakes ; regulating and controltransmitting gear.- A winch is fitted with driving-gear embodying conjointly-controlled clutch and brake mechanism, and with additional braking-means acting automatically m the event of the load overrunning during lowering. The barrel a is driven through spur gearing d, e of which the loose pinion e is connected rigidly to a friction drum g also loose on the driving- shaft f. The drum g bridges the abutting ends of the driving-shaft and a fixed shaft k, and two sets of alternating friction discs are provided between the drum and the driving-shaft in one case, and between the drum and fixed shaft in the other case. Thus by moving the drum axially to the right in Fig. 4, the drum and pinion will be connected to the driving-shaft to transmit the drive, while by moving it to the left, the drive will be disconnected and the drum braked by engaging the discs on the fixed shaft. In the mid-position both sets of discs will be disengaged and the load free to run down. A handle h and links q are used to position the drum. A loose sprocket wheel r on the drum shaft, driven continuously by a chain from the driving-shaft, rotates in the same direction as the lowering drum. A roller clutch between the sprocketwheel and the spur-wheel d comes into action when the drum overruns the sprocket-wheel and locks the drum to the driving-shaft to prevent faster rotation than would be obtained by a positive downward drive.

Abstract: 416,718. High-speed spinning, doubling, and twisting machines. FERRANTI, G. R. Z. DE, (Executrix of FERRANTI, S. Z. DE), Wood Green Farm, Upper Basildon, Pangbourne, Berkshire. Feb. 13, 1933, No. 4341. [Classes 120 (ii) and 120 (iii).] In machines for spinning, doubling, and twisting at high speed, especially machines of the kind first described in Specification 18047 /03, [Class 120], the spindle apparatus comprises an outer running tube 27, Fig. 3, carrying the bobbin and provided with a brake drum 29, and an intermediate bearing tube 30 resiliently supported on a dead spindle 31 and provided with a thrust bearing at the top for the running tube. The invention is described as applied to Ferranti machines, such as described in Specifications 18047/03, 18260/04, or 24941/06, [all in Class 120]. The intermediate tube 30 is supported on the dead spindle by resilient cages 43, 59, comprising rings 44, 45, Fig. 8, connected by springs 46, and with a spring damping-device 47 comprising a split ring 51, Fig. 10, carried by washers 49, 50 supported by resilient washers 54, 57 and a spring 56. The damping-device is situated approximately midway of the tube 30, but the position is not material. The tube 30 is provided with a graphite plug 34 which is bored centrally to receive a valve pin 33 at the top of the running tube and is seated on a swivelling air-connecting piece 39 on the dead spindle, the valve 33 permitting air to pass to lift the running tube to an extent determined by the exposure of a leakage-hole in the tube. The tubes are formed of electrodeposited copper and the tube 30 is provided with carbon bearing surfaces for the tube 27. The brake drum 29 is formed of brass and is engaged by a band 61, Fig. 15, carried by a pivoted bracket 62 pressed by a bracket under control of a spring coiled around its pivot. An aneroid device 73 is provided normally to withhold the spring bracket from the bracket 62, but when air is shut off from the machine the aneroid collapses and the brake band 61 is strongly applied. The valve of the aneroid is connected with a wire 142 engaged by the yarn so that the brake is also applied when the yarn breaks or the supply fails. The brake may also be removed by a thumbpiece. The brake-band is subsidiarly controlled by a spring 69, when the spring bracket is withheld by the aneroid, so as to adjust the drag, a lever 66, engaged with a slot 71 in the control lever of the spring 69, being moved by a ramp 70 on a rod which follows the movements of the spindle rail and, in addition, has a relative horizontal movement so as to vary the braking effect in such manner that during the complete filling of the bobbin the drag on the bobbin is at first increased gradually until the bottom is wound and is then gradually decreased. The bobbin consists of an electrodeposited copper tube and is driven by the tube 27 by means of slotted steel rings 74, 75. Specifications 416,717 and 416,719 also are referred to.

Title: Improvements in scaffolding clips
IPC: E04G7/18
Filed: 1945-02-26
Abstract: 587,028. Scaffold clamps. SKINNER, H. J. P. Feb. 26, 1945, No. 4804. [Class 20 (ii)] A scaffold clamp for standard and ledger couplings of the type having a U-shaped member 3 embracing the standard 2, the limbs 4, 5 of the U projecting beyond the standard and being recessed as at 6 in their upper edges to receive the ledger 1, has the recesses wedge shaped and so dimensioned, and the inclined edges 8 of the recesses so positioned that a load on the ledger tends to force the latter downwardly into the recesses and both the ledger and U-shaped member more firmly into frictional engagement with the standard, without any tendency for the U-shaped member to tilt. The necessary condition for this is that the line of the reaction force between the ledger and the edges 8 shall pass below the upper edge of that part of the U-shaped member which contacts the standard on the side remote from the ledger. Additional means may be provided to force the ledger into the wedge shaped recesses comprising a two hooked member 18 engaging over the ledger on either side of the limbs 4, 5, the edge of the part of the member joining the hooks engaging cam shaped surfaces formed on the bottom edges of the limbs 4, 5. The cam surfaces may be provided with ratchet teeth for further security. The hooked member is hammered into position by striking the portion joining the hooks or may be forced into position by a suitable forked tool engaging this portion. The hooked member and the U-shaped member may be formed from spring steel. To prevent the U-shaped member from slipping down the standard when assembling the joint a rod 11 is provided passing through holes 10 in the limbs of the U-shaped member, and contacting the standard with a serrated cam shaped portion 14. Slipping causes the rod to rotate and the standard is gripped between the rod and the base of the U-shaped member. To facilitate assembly of the clamp the rod 10 may be withdrawn until its flanged end 15 fits in a corresponding recess 17 in one limb 5 of the U-shaped member whereupon this member can be engaged round the standard. The rod is then pushed across and engaged in the hole 10 of the limb 14, this being possible by virtue of a recess 13 provided in the rod, until the serrated surface 14 contacts the standard. The flanges and 15 and 16 are provided on the rod to prevent it being removed from the U-shaped member. The rod 11 may be replaced by a screw passing through a screw-threaded hole in one of the limbs 4, 5 and engaging the standard.
