Title: Vertical conveyors
IPC: B65G17/12
Filed: 1965-07-22
Abstract: 1,055,116. Endless elevators for articles. RAPIDS-STANDARD CO. Inc. July 22, 1965 [July 31, 1964; March 4, 1965], No. 31266/65. Heading B8A. A vertical conveyer 10 comprises a pair of primary chains 13 and a pair of secondary chains 14. Carriages 40 are arranged at equally spaced intervals on the conveyer 10 and each is made up of a plurality of intermediate links 41, Fig. 6 (not shown), a free end link 42 and a captive end link 43. Each link consists of a pair of side plates 44 connected by a rod 45 or 45a collectively forming a load supporting platform. Tie links 46 connect the lower ends of the links 41, 42, 43 so that the carriage 40 may flex convexly but not concavely. The captive end link is pivotally secured to the primary chain 13 and a pair of laterally spaced fingers 48 extends from the rod 45a to co-operate with lift bars 49 on the secondary chain pair. Rails 60 support the carriages 40 on an upper run 34, Fig. 8 (not shown), of a lower horizontal leg 35. Clamping plates 70, Fig. 5 (not shown), on the primary chains 13 hold the carriages 40 against guide discs 27 to ensure smooth transition around the bend, prevent the carriages 40 from swinging outwardly in a first vertical leg 30 and prevent the carriages from flexing downwardly in a lower run 35 of the horizontal portion 33. The conveyer 10 may run in either direction receiving loads from or discharging loads to wheels 75, 76. Ramping plates 61 or wheels 62, Fig. 7 (not shown), dampen the transition in the direction of movement of the carriage 40 from horizontal to vertical movement or vice versa.

Patent GB-728778-A (GB)
Title: Improvements in or relating to apparatus for removing liquid from a wet running yarn
IPC: D01D10/04
Filed: 1952-12-11
Abstract: <PICT:0728778/IV (a)/1> <PICT:0728778/IV (a)/2> Apparatus for removing liquid from a wet running yarn, e.g. a freshly coagulated artificial-filament yarn, comprises one or more suckers each comprising a tubular member provided, as its only opening to the atmosphere, with a transverse slot communicating with the interior of the member, in combination with means for applying suction to the interior of each member and thereby drawing air through the slot into the interior of the member and with means for causing the yarn to travel through the slot or slots.  Preferably the axes of all the tubular members lie in a single plane, and the slots all lie in a single plane normal to it.  Preferably, also, some liquid is removed from the yarn by means of a wiper or wipers arranged in advance of the suckers.  As shown in Fig. 2 (a front-elevational view, partly in section), a yarn 11 passes upwardly together with a stream of liquid through a conduit 12 and then through a chamber 13.  Part of the liquid which the yarn carries up from the conduit 12 is wiped from the yarn by causing the yarn to pass through vertically aligned slots 24, 26 in two short sloping cylindrical rods 25, 27 mounted on a vertical header 21 having its upper end closed by a cap 22 and its lower end passing through the wall of the chamber 13 to a coupling 23.  The liquid discharged from the conduit 12 and dripping from the wipers 25, 27 escapes from the lower end of the chamber 13 through an outlet conduit 17, 18, 19 provided with a screen 20. The yarn passes upwards from the wipers 25, 27 through vertically aligned slots 32 in four suckers each comprising a tubular member 29 having one end communicating with the interior of the header 21 and the other end closed by means of a screw 31.  The header 21 is connected by means of the coupling 23 to a source of suction (not shown).  The yarn after leaving the uppermost tubular member contacts a rod yarn guide supported by the header 21 and then passes through an annular yarn guide 34 in the top of the chamber 13 to the pulley 35.  In a modification the slots 44, 46 (Fig. 6) are on opposite sides of the wipers 45, 47 respectively and extend to a depth short of the axes of the wipers.  Similarly the slots 54 in the suckers 51 are on alternate sides of the tubular members and do not extend as far as their axes.  As a result the yarn 43 passing through the apparatus is forced into a zig-zag path, and is to some extent flattened.  The ends 48, 49 of the wipers and the ends 53 of the suckers are bevelled so as to facilitate the initial guiding of the yarn into the slots when threading up.
