[Class 78 (i)] In apparatus for delivering fuel to kilns, furnaces or other solid fuel consuming equipment, a conveyer discharges the fuel at each mouth of the equipment into a receiver having a displaceable support on which the fuel piles up while it is at rest and which is actuated at intervals to discharge the fuel into the mouth. In one construction a tube 74, Fig. 1, which encircles the kiln, is provided with a number of apertures 75, there being an aperture for each mouth of the kiln A drag ; chain, or equivalent conveyer, contained in the tube transports the fuel to the apertures through which it passes into a number of vertical shoots 76, each of which is closed at the bottom by a longitudinally movable plate 78. A lug 79 depending from each plate is attached to a piston rod 80 which is reciprocated by pressure fluid admitted to the cylinder 82. A cam-way 83 on the underside of each plate actuates a roller 84 which is mounted on the arm of a bell-crank lever. The other arm 86 of the lever is connected by a link 87 to an arm 88 on the spindle of a valve 42 in. the shoot 41 leading to the furnace By these means the mouths are opened only when fuel is being discharged from the plates 78. The admission to, and the cut-off from, the cylinders of pressure fluid is controlled by a slide, or semi-rotary, valve operated by a solenoid or motor which is in turn controlled by known time-temperature responsive mechanism. The contacts of this mechanism close only when the furnace requires charging. In another construction the drag chain conveyer and tube are replaced by inclined belt conveyers 89, Fig. 6, and each shoot 76 is provided with a lip 91 which directs the overflow on to the next conveyer. The driving drums of the belts are driven by pistons through ratchet devices, masking plates being provided to vary the number of teeth exposed according to the speed off travel required of each belt. The pistons are actuated by the pressure fluid used to reciprocate the plates 78.

Title: Improvements in or relating to the manufacture of metal tubes or metal sheaths of electric cables
Inventor: PENROSE JAMES RONALD
IPC: B21C3/12
Filed: 1955-06-09
Abstract: 785,654. Spinning tubes. PIRELLI-GENERAL CABLE WORKS, Ltd. April 20, 1956 [June 9, 1955], No. 16577/55. Class 83 (4). A method of reducing the diameter of a metal tube consists in subjecting the external surface of the tube to the action of a tool having an operative surface which is concave toward the tube and is formed by a generatrix parallel or slightly inclined to the axis of the tool, the nearest point on the said operative surface to the axis of the tube being at a.less distance from the tube axis than the external radius of the tube as unreduced, moving the tube in the direction of its axis and simultaneously producing relative rotation between the tool and the tube, whereby deformation of the tube along a helical path is effected. A tube reducing machine comprises a head 1 rotatably mounted on a fixed frame 2 and driven by a gear 5. A bush 6 in the head supports the unreduced portion of the tube 7 and a bush 8 supports the reduced portion 7a, these bushes 6 and 8 being fitted respectively within rings 9 and 10 by means of roller bearings 11 and 12. A further ring 13 located between and secured to the rings 9 and 10 encloses a diametrically adjustable tool holder 14 which carries the tubereducing tool 15. A micrometer head 21 assists in setting the desired eccentricity to the tool 15. The lead-in portion of the tool is flared and the exit edge slightly rounded. A plug 25 carried on a stem 26 supports the tube just before the points of application of the tool which may be rotatably mounted on the head 14 by means of a ball bearing 16 to impart a rolling action on the tube instead of a rubbing action. The machine may be used for reducing a cable sheath on to the cable core, a hollow plug being used in place of the plug 25. The tool may be inclined to the tube axis and reduction may be effected in stages by arranging two or more tools to operate on tandem. Alternatively, the tool may remain stationary and the tube rotated about an axis parallel, but eccentric to its own axis.

Abstract: 297,700. Hunt, S. June 22, 1927. Blowing.-In rotary machines for the manufacture of blown glass articles such as bottles, in which a number of carrier units rotates about a central column and blowing or equivalent valves on the units are actuated by follower levers riding against a fixed central cam comprising a number of stepped layers or having a stepped, coned &c. surface, the follower levers are mounted about axes parallel to the cam axis and carry bowls or rollers with means whereby any individual follower lever or cam-bowl can be adjusted to cooperate with any cam step without modifying the effective length of the follower lever arm. Where the movements are transmitted to the valves through secondary levers, means are also provided to maintain constant the stroke relations thereof for all adjustments of the cam controlled elements. In the arrangement shown in Figs. 1 and 2, the follower lever 16 carrying a cam bowl 19 is splined to and vertically adjustable on a spindle 20, a pivoted catch 34 mounted in the lever boss 29 being pressed by a spring pin 33 into engagement with one of a series of notches 31 in the spindle. By retracting the catch 34, the lever can be adjusted to bring the roller 19 level with any desired step of the fixed operating cam (not shown). The range of adjustment may be doubled by inverting the roller carrying pin 22. The valve 14 is actuated through a secondary lever 37 on a pin 38 and having an adjustable screwed contact stud at each end, the upper stud 43 being provided with a notched head 44 adapted to be locked by a detent 46. So that the acting lengths of the arms of the lever 37 may be unaffected by vertical adjustments of the follower lever 16, the stud 43 bears against a side plate 35 thereon. The lever 37 may be parallel to the lever 16 with transmission through a plate such as 35 on either member and an ordinary lever connection therefrom to the valve. In an alternative arrangement, the lever 16 carries an extended pin 22, Fig. 5, and the cam roller 19 may be arranged thereon in various positions either by the use of packing washers or by using a selection of sleeves 23 with differently located collars 19. To extend the range of adjustment the pin 22 may be inverted and the lever 16 itself may also be adjustable as in Fig. 1.

Abstract: 835,115. Haymaking. VAN DER LELY N.V., C. May 30, 1956 [June 4, 1955], No. 16779/56. Class 6(3). A raking device of the type comprising rake wheels mounted in echelon formation on a frame is provided with a stopping or separating member associated with at least one rake wheel for the purpose of preventing the crop delivered by the rake wheel from being displaced too far in the delivery direction, thereby assisting in the conversion of a given number of swaths into a greater number of smaller swaths. As shown in Fig. 1 the raking device comprises rake wheels 8, 9, 10 and 11 mounted for free rotation on a frame attached to the power lift links of a tractor 1. Mounted behind each rake wheel, on the frame member 31, is a separating wheel 38 having the form of a ratchet wheel whose teeth constitute times for engaging the crop (see Fig. 2). Each wheel 43 is mounted for rotation at the lower end of a vertical shaft 48 rotatably housed in a bushing 49 fixed to the frame members 31. At the top of the shaft 48 is fixed a link 52 connecting the shaft to a strip 55 which runs the whole length of the frame member 31, and to which each of the separating wheels is attached in like manner. The inclination of the separating wheels to the direction of travel of the implement can therefore be varied by moving the strip 55 longitudinally and fixing it in the desired position by means of a pin engaging one of the holes 60. Springs 53 and 54 encircling the shaft 48 allow a limited vertical displacement of the wheel 43. In the embodiment shown in Figs. 3 and 4, the rake wheels are mounted in pairs on a looped frame 70, a separating wheel 95 being provided with each pair. In this case, each separating wheel is mounted on a member 89 fixed to the axle 75 of one raking wheel of the pair and bearing two horizontal pins 90 and 91. A bell crank lever having arms 92 and 92A is rotatably mounted on the pin 91, the longer arm 92 supporting the separating wheel 95 and the shorter arm having a pin 96 connected by a spring 97 with the pin 90, the spring serving to urge the wheel into contact with the ground, or when the wheel is put by hand into the dotted position, serving to keep the wheel in an inoperative position.
