      <title>DEVELOPMENT AND MANUFACTURE OF PRE-STRESSED CONCRETE SLEEPERS</title>
      <link>https://trid.trb.org/View/6560</link>
      <description><![CDATA[The Tallington factory, completed in August, 1944, has 20 lines, each accommodating 100 standard main-line sleepers. Filling the moulds at one fixed place in the production line, allowed a vibrating table to be used and a water cement ratio of 0.39 for the concrete.  For wiring, the coils of wire are carried on a track and the wires are drawn off under semi-tension, which obviates the need of first straightening the wires.  As they leave the wire carrying truck they are automatically cleaned by passing through a scrubbing box containing carborundum granules. The method of manufacture allowed three minutes of working time per pair of sleepers during concreting and removal, this time factor also being maintained for the wiring processes.  The reduction in labor costs using the mechanized mass-production process showed a savings of 88 percent over an earlier method described.]]></description>

      <title>WELDING IN LOCOMOTIVE CONSTRUCTION</title>
      <link>https://trid.trb.org/View/11291</link>
      <description><![CDATA[A new automatic flash-butt welding machine at Doncaster Works, L.N.E.R. is described and illustrated.  The machine has a welding capacity of 12-1/4 sq. in. cross section area.  The clamps are operated by pneumatic clamping cylinders through heavy steel levers.  Incorporated in the butting cylinder is the A1 patent automatic dashpot control gear which gives a wholly automatic action to the welding operation.]]></description>

      <title>AUTOMATIC METALLIC ARC WELDING</title>
      <link>https://trid.trb.org/View/11322</link>
      <description><![CDATA[An automatic metallic arc welding machine, which was designed and manufactured by Metropolitan-Vickers Electrical Co., Ltd., consists of a motor-operated, rotating jig; on to which the folder U-shaped end of the wagon body is located and clamped together with the stiffening bars, which are also located by clamps.  Long straight butt or fillet welds, whether longitudinal or circumferential, are obvious choices for automatic welding. A typical application for the use of continuous automatic welding is that of welding tee or angle stiffener bars on railway mineral wagons.  The estimated hand-welding time for each 40 in. pass was six minutes, and the automatic welding time five minutes.  In the case of an axlebox made up of 1/4 in. thick pressed U-shaped section forming the bottom and sides and involving 13 welds, a comparison shows a saving of one minute with automatic welding.]]></description>

      <title>PRODUCTION OF ANTI-FRICTION BEARINGS</title>
      <link>https://trid.trb.org/View/11324</link>
      <description><![CDATA[British Timken Limited established at their Birmingham works a department expecially equipped for large-scale production of axleboxes of the common-type.  The first group of operations for which a special machine was evolved was for the boring and facing of both ends.  To obtain maximum concentricity of bores at each end of the housing it was desirable to carry out the operation on a machine in which the housing would rotate.  The problem was resolved by the installation of a large double-ended, hollow spindle, boring and facing machine, the bore of the head being such that it would accommodate the largest housing.  Considerable economy in machining time resulted by the installation of a Cincinnati duplex horizontal miller with the heads designed to feed vertically thereby eliminating the new setting required for each end of the axlebox.  A multi-spindle horizontal drilling machine was installed to improve economy of drilling, specially on split-type designs.]]></description>

      <title>CREOSOTING OF TIMBER</title>
      <link>https://trid.trb.org/View/11372</link>
      <description><![CDATA[The article, digested from a lecture, discusses the preservation of sleepers and other forms of railway timber by the "full cell" process.  Other methods of treatment and a description of Baltic Redwood and its felling, haulage, transport, and manufacture into sleepers are also dealt with, however, as well as a typical creosoting depot and its activities.  The laying of the sleepers and chairing processes are given.]]></description>

      <title>ROLLING STOCK WHEEL TREPANNING MACHINE</title>
      <link>https://trid.trb.org/View/11394</link>
      <description><![CDATA[The machine has four identical spindles mounted in separate heads, two with horizontal adjustment, and two with vertical adjustment.  The spindles can be readily arranged to deal simultaneously with two, three, or four holes, and to cover a wide range of wheels of varying diameters.  Cutter spindle speeds range from 12 to 69 rpm. suitable for dealing with holes from 1-1/2 to 6 in. dia.  The drive is by means of two separate 15-hp constant-speed motors with worm reduction gears and two eight-speed change gearboxes.  As well as trepanning the large sprag holes, the machine is also capable of drilling smaller holes in disc wheels.]]></description>

      <title>ALL WELDED RAILWAY TANK WAGONS</title>
      <link>https://trid.trb.org/View/11371</link>
      <description><![CDATA[Some time ago the Swedish firm commenced building all-welded tank wagons differing considerably in design and construction from the usual type.  The Olsson wagon has no separate underframe but instead, at each end, a fixed two-wheel frame welded to the tank, and consisting of bearing forks, buffer beam, draw box, and cross bars.  These end parts carry buffer, draw gear, spring suspension, brake mechanism, and so forth.  The tank is strong enough by itself to support the load, and also to withstand all drawgear and buffer forces.]]></description>

      <title>RAIL-WELDING IN SOUTH AFRICA</title>
      <link>https://trid.trb.org/View/6862</link>
      <description><![CDATA[The first of six flash-butt rail welding depots on the South African Railway is in operation and the method of producing 120 ft. welded rails is briefly described. The Thermit or Boutet process is used for welding. Existing rolling stock has been converted to insure safe transport of the rails to the point of use.  An unloading system is used whereby the rails are unloaded from the converted bogie vehicle as they are being laid on the track.]]></description>
