Title: Improvements in mast arrangements for fork lift trucks
Inventor: WRIGLEY ARTHUR
IPC: B66F9/08
Filed: 1962-04-30
Abstract: 1,015,665. Fork lift trucks. WESSEX INDUSTRIES (POOLE) Ltd. Aug. 30, 1963 May 30, 1962], No. 16457/62. Heading B8H. A fork lift truck 1 includes a slidable inner mast comprising channel sections 5 with two sets of three rollers 4 running in channel members 3 forming an outer mast mounted for pivotal movement about a horizontal axis 2. The inner mast is longer than the outer mast, but, as the channel members 3 are free of obstruction, the inner mast can be lowered so that it projects below the lower end of the outer mast, the lower roller 4 of each set of three being inoperative, but alignment between the masts maintained by the upper rollers 4. This enables an increased lift to be provided without increasing the overall height of the mast assembly when the inner mast is fully lowered. Forks 13 are mounted on a plate 12 on a carriage 10 running on rollers 11 in the inner mast. The carriage is supported by a pair of chains 14 running over grooved pulleys 16 and attached to tension rods 18 fixed to a plate 19. A ram 7 lifts the inner mast and the pulleys 16 so that as the inner mast rises the carriage 10 runs up the inner mast. (Fig. 7 shows an intermediate position.) The arrangement is such that the forks 13 are lifted slightly before the inner mast is engaged by the ram 7. The plate 12 may carry hydraulically operated squeeze clamps which may incorporate a side shift (not shown).

Title: Improvements in and relating to automatic lathes
IPC: B23B11/00
Filed: 1943-10-12
Abstract: 571,006. Lathes. METALLIFACTURE, Ltd., and PICKERELL, A. W. Oct. 12, 1943, No. 16673. [Class 83 (iii)] An automatic lathe having mechanism for effecting repeated to-and-fro traverse between the work and tool, the traverse in one direction being produced by temporary engagement between a continuously rotating lead screw and a half-nut and also having mechanism for effecting relative approach between and retirement of, the tool and work at, respectively, the start and finish of each traverse in one direction, is characterised by means for maintaining the half-nut in engagement with the lead screw, comprising a stationary former extending in the direction of traverse and a member engageable with the former at the commencement of traverse, thereby to hold the half-nut in said engagement until the termination of the traverse. The lathe comprises a headstock 10, tailstock 11 and saddle 12 carrying a slide 15 with tool post 17 and adapted to be traversed along the bed 13 by a lead screw 14. A cam 24 slidably keyed to a cam-shaft 25 operates levers 27 and 29, the latter having a hook 30 to engage a projection 31 on the slide 15 and move it, against the action of a spring 23, towards the work and until a half-nut 19 mounted on the slide engages the lead screw 14. As the traverse begins, a projection 20 on the slide is moved into engagement with a stationary former 21 which holds the slide forward. At the end of the traverse the projection 20 is released and the slide is retired at first by the action of return former 22 (not shown) and then by the action of the spring 23 until a ramp 43 thereon depresses a spring plunger 44 to move another half-nut 40 into engagement with a second load screw 39 to effect the reverse traverse, at the end of which one or other of two inclined limit stops 46, 47 lift the nut 40 out of engagement with the screw 39. The cycle is then restarted by the engagement of the cam-operated arm 29 with the slide 15. Engagement between the arm 29 and projection 31 except at the end of the reverse traverse is prevented by means of a bar 32 which lifts the arm 29 and allows it to drop into engagement only when a stud 37 carried by the slide enters a notch 36 (not shown) on the underside of the bar. During the working traverse, lubricant is fed to the work from a tank 52 by means of a cylinder moving with the saddle over a fixed piston. In a modification, the two lead screws are adjacent and the half-nut 19 is threaded on two opposite faces, movement into engagement with one or other of the lead screws being effected by cams on the shaft 25. The lead screw is mounted in a combined thrust-andjournal bearing at one end and in a plain bearing at the other end to facilitate the changing of the screw.

Title: Pneumatic nailing machine
IPC: B25C1/00
Filed: 1965-04-21
Abstract: 1,033,870. Nailing-machines. K. REICH. April 21, 1965 [April 25, 1964], No. 16753/65. Heading B4C. A pneumatic nailing machine comprises a percussive piston 66, Fig. 1 (not shown), movable in a cylinder 3, which is surrounded by a chamber 89 connected with the compressed air supply line 58 and an inlet opening 105, a tubular valve 94 being provided for controlling the flow of air through the inlet opening. The valve 94 is controlled by air fed from the line 58, to a chamber 81 via passage 76, ball valve 73, passages 77, 78. A nail conduit 25 is pivoted at 27 in the machine housing and coupled to a control piston 36 which is provided with an extension 72 for lifting the ball valve 73 off its seat 75. In operation, compressed air is fed through line 58 and passes via ports 57, 59 into a chamber 61 thereby moving the piston 36 so that it pivots the conduit 25 into alignment with a barrel 8 in order to permit a nail 23 to be fed therein. The valve 94 is held in contact with a seat 92 so that air is prevented from entering the inlet opening 105. Upon depressing the valve 47, the air flows via the port 57, a groove 51 in the valve 47, port 46 into a chamber 45, thereby moving the control piston 36 to the position shown, whereby the conduit 25 is moved out of alignment with the barrel. Movement of the piston lifts the ball valve 73 off its seat so that the air passes, via a passage 76 and passages 77, 78, into the chamber 81 so as to lift the valve 94 off its seat and permit the air to enter the inlet opening 105 and so drive the percussive piston on its working stroke. During this stroke, the air trapped in front of the percussive piston is moved into an annular storage chamber 88; a valve 63 is operated by the piston at the end of the working stroke so as to actuate a nail feeding mechanism in readiness for the next working stroke. When the valve 47 is released the control piston 36 and ball valve 73 are returned to their initial positions and the percussive piston is returned by the compressed air stored in the chamber 88; the latter piston is retained in its inoperative position by means of a locking member.

Abstract: 1,220,373. Distillation apparatus, multiple-effect type; desalination of sea water. UNIVERSAL DESALTING CORP. 9 April, 1968 [12 April, 1967], No. 17041/68. Heading B1B. Seawater, or other liquid, is distilled in a multiple-effect apparatus comprising bundles of horizontal tubes 1, the bundles being stacked one above another, wherein the preheated seawater, supplied from the top distributing pan 4, flows down over the outer surfaces of the tubes. Heating vapour, such as steam exhausted from a turbine, is supplied through pipe 21 into the tubes of the uppermost bundle. The tubes of each lower bundle are heated by steam which has been evolved from the seawater flowing over the tubes of the preceding bundle, this steam flowing to the tubes via demisters 25, chambers 23, passages 24 and distributing chamber 6. The condensate, i.e. desalinated water, formed in the tubes of each bundle (except the top one), flows together with uncondensed vapour into a chamber 7 which contains a heat-exchanger 11, wherein the residual vapour is condensed. The lowermost effect IX is divided into two separate liquidflow sections. Seawater to be desalinated is de-aerated and then passed through pipe 12 and over the tubes of effect IX-B where it is heated to boiling (at the low pressure prevailing in effect IX). The seawater is then pumped through pipe 16 and the U-tubes of heat-exchangers 11 to the top pan 4, whence the seawater flows through orifices over the tubes of the uppermost bundle. The seawater dripping off these tubes is received by collector 5, and then flows through conduit 17 and manifold 18 into the distributing pan 4 of the second effect. In order to preserve a pressure-differential between successive effects, a valve 19 is provided in each conduit 17. Effects VIII and IX are of larger volume than the preceding effects. Seawater from effect VIII flows to effect IX-A. Steam produced in effects IX-A and IX-B is led to condenser 26 which is cooled by seawater led in through inlet 27a and discharged through outlet 27b. Concentrated seawater leaves effect IX-A through pipe 20. The condensate collected in the chamber 7 of effect II flows through valve 30 to a tank 29 where it flows over weir 29a and partially flashes into vapour. The vapour flows into chamber 23b. The condensate flows through valve 32 to the flash tank 29 of the next effect. The cooled condensate flows from the flash tank of the last effect through conduit 33 into the chamber 34 of condenser 26, and is withdrawn as product through line 35. Air is removed from each chamber 7 via a Venturi-type nozzle leading to a common line connected to a vacuum pump. In a modified apparatus, the vapour from the last effect is compressed, and then used to heat the tubes of the first effect. The compressor may be driven by a turbine actuated by steam withdrawn from one or more of the effects.
