Abstract: 516,976. Step-by-step conveyers; crushing mills; rotary furnaces. ANDERSON, N. R. July 13,1938, No. 20713. [Class 78 (i)] [Also in Groups II and XII] A conveyer suitable for use in such processes.as drying, roasting, retorting, calcining, carbonising, filtering, evaporating and precipitating comprises an outer member and a coacting inner member, each of which is provided with one or more material supporting surfaces, and to which are imparted longitudinal and rotary movements of such a character that the material is transf e r re d alternately from one member to the other and is moved along them in a step-by-step manner. In the form shown in Figs. 9A ... 9E, the outer member 30 is tubular and has an intermittent movement of rotation. The inner member 80' is slightly less wide than the bore of the member 30 and has surfaces 83, 85 on which material can rest. It is reciprocated and turned about its axis. Pieces of material a, b, c, d take up the positions shown in successive figures as movement of the members 80, 30 takes place. If one end of the member 30 is closed, these movements can be used to feed material in and out of the other end. The outer member may be a corrugated sheet, and the inner members troughs of semi-circular cross-section or. angle irons. A flat or corrugated sheet may be used to cover the outer member.' A retort is shown in Fig. 6 through which the material is conveyed as above described. The material is placed in a feed box 39, one side 35 of which supports the outer tubular member 30. The inner wall 35A of the discharge bin 41 supports the other end of the member. An angular-section inner member 33 passes through the member 30 into the bins, and is connected by a bent rod'46 to a shaft 47 driven by rack-and-pinion mechanism 97, .98 mounted on a stand 96. The rack is connected to the piston of a double-acting hydraulic cylinder 99, and the stand, which is slidable in guides 100, is coupled to the piston of a similar cylinder 101. A sealing plate 51 on the shaft 47 is connected by a canvas or asbestos sheet bellows 52 to the sides of the bin 41. Slots 54 are cut.in the top of the member 30 to permit the escape of gas. These slots may be replaced by a pipe 55. The conveyer may also be used for the removal of deposits from liquids, e.g., the solids which are deposited during the concentration of brine. The tubular members 30, Fig. 8, connect headers 105, 107, the former of which is divided into compartments by a plate 111 and has an inlet 106 and and outlet 108. Each tube 30 contains an angular member 33 which is connected to a driving shaft 47 as shown in Fig. 6. In another modification the outer tubular member is mounted on wheels and is reciprocated by a cam disc while the inner member is rotated by a pulley. The apparatus may be arranged to have a crushing action by providing teeth or projections on either or both of the members.

Abstract: 455,390. Card teeth for textilepreparing machines. HOLDSWORTH, A., Marsh Works, Colwyn Street, Marsh, Huddersfield. July 23, 1935, No. 20868. [Class 120 (iii)] In the production of card teeth or staples, Fig. 1, having points formed by cutting the wire at an angle to its axis, a cutter is employed having a single cutting edge disposed at the appropriate angle to the axis of the wire with means for rotating the wire between successive cutting operations through 180‹ first in one direction and then in the other. The wire a, Fig. 3, is fed forward by a feed box comprising a rotatable tube b having a chuck f and mounted on a bracket d slidable in a bed e. A bellcrank lever h is pivoted at h<1> on the bracket done arm bearing against the end of the chuck f while a roller h<2> on the other arm engages the face of an arm i carried by a reciprocable rod i<1>. A pinion m, Fig. 2, fast on the tube b meshes with a rack n which is reciprocated by a cam r engaging a saddle piece p. In operation, a slide bar k having an inclined face k<1> is moved forward to engage an inclined face j<1> and move the bracket d forwardly in the direction of feed of the wire a, the clamp w being open and the chuck f closed. This feeds a length of wire forwardly through the die x, Fig. 4, and during this feeding movement the tube b is rotated through half a revolution by the rack n and pinion m. The clamp w is then closed and the cutter y operated. The bracket d is then moved back to a stop z by a spring, the chuck f being open and the cam r rotating through a quarter revolution clear of the saddle piece p. The clamp w is then opened, the chuck f closed and the bracket b then commences another forward movement during which the tube b and wire a are rotated through half a revolution in the opposite direction.

Abstract: 240,621. British-American Laundry Machinery Co., Ltd., (American Laundry Machinery Co.). Sept. 6, 1924. Rotary containers; air, controlling circulation of; charging and discharging; driving mechanism, application of; humidity, controlling.-Apparatus for drying materials particularly textiles, &c. in batches comprises a rotary perforate drum 12 mounted in an inclinable casing 1, the material being subjected to the circulation of a current of air which is drawn by a fan 31 through an opening 21 into a duct containing trays of calcium chloride and thence through an adjustable opening 22 and the perforations 28 in the drum to the outlet duct 30. When dried, the batch of material is automatically ejected from the drum by means controlled by a psychrometer 61, which is affected by the humidity of the circulating air, and which, through electromagnets and switches, actuates mechanism for tilting the casing on its axis 3 and opening the discharge door 43 of the drum. The drum and the fan are driven by independent motors and the feed doors 39, Fig. 6, and the discharge door 43 are held closed by electromagnets 42 and 47, Fig. 5, respectively. When the humidity of the circulating air reaches a predetermined point the psychrometer 61, which is of the kind described in Specification 240,618, closes an electric circuit thus actuating a motor 10 which raises the casing on its axis 3 and by the engagement of the screw 56 with the tripper 57 accelerates the speed of the drum, stops the fan motor, and opens the feed and discharge doors of the drum so that the dried batch is discharged from the drum while another batch is introduced therein.

Abstract: 316,220. Siemens & Halske Akt.- Ges. July 25, 1928, [Convention date]. Electromagnetic current and pressure meters.-A measuring instrument, such as a dynamometric recording instrument, is protected against damage due to short-circuits bv means of a flexible coupling connecting the moving coil or other part on which the turning movement is exerted and the remaining parts of the movable system, which are preferably strongly damped, so that the force transmitted thereto is insufficient to cause damage. A recording- instrument of the iron-enclosed dynamometer type is shown, in which the movable coil 1 is sufficiently robust not to be damaged by impact with a spring-mounted stop 14 due to a sudden overload. The coil 1 is mounted on a tube 3 with which the system spring (not shown) also engages. The tube 3 is loosely rotatable on an axle 4, on which are fixed an arm 5 pivoted to the recording lever 6 at the point 7 and an arm 8 carrying a damping sector 9 which moves between the poles of a permanent magnet 10. The tube 3 and the axle 4 are connected by a spring 11, so that the parts carried by the axle 4 do not immediately follow a sudden movement of the coil 1, but their motion is strongly damped so that no damage is caused when they reach the stop at the end of the scale. Alternatively the moving coil may be carried by the axle and the other parts by the tube.

A spool-supporting arbor comprises one or more deformable members 7, 8 on a rotatable shaft 1, onto which a spool can be slid from one end, each member 7, 8 being capable of expanding radially, means 9 to expand each member 7, 8 so as to tightly grip a spool 17 surrounding the shaft 1, and stop means 14 to move radially with respect to the shaft 1 on rotation thereof to extend outwardly of the shaft 1 at or adjacent to said one end. The members 7, 8 comprise rubber rings positioned between a shoulder 4 and a metal tube 5 and between metal tubes 5, 6, respectively. In operation, the spool 17 is slid onto the metal tube 1 to abut against a head 2. Urging means 9, comprising a threaded stem 10, is screwed into a cavity 11 in the tube 1 by inserting a rod into holes 13 until the rings 7, 8 grip the spool 17 sufficiently tightly. Stop means 14 prevent the spool 17 sliding off the arbor during winding, e.g. due to the means 9 being insufficiently tightened, and each is normally held retracted in a bore 15 in the tube 6 by a spring 16. Upon rotation of the arbor above a certain angular velocity the stops 14 slide out to project beyond the tube 6.
