Title: Heel fashioning mechanism for straight bar knitting machines
Inventor: ZESCH EUGENE MAX
IPC: D04B11/06
Filed: 1947-09-11
Abstract: 642,682. Knitting- machines. LIEBERKNECHT, Inc., K. Sept. 11, 1947, No. 24985. [Class 74 (ii)] A straight-bar machine is adapted for knitting heel tabs by the inclusion of elements which press end groups of needles from behind against the presser bar, the normal pressing movement of the needle bar being prevented during the formation of the heel, the elements resting on and rising and falling with the the needle bar. The elements 100, 101 are pivoted at 102 to rise and fall with the needle bar 20. Their pressing movements are derived from a cam 111 on the main cam-shaft 30 through a roller 110 and an arm 109, a lever 112 on the pivot shaft 105 of the arm 109 engaging a stop 113 to limit this movement and being acted upon by a spring 115 to produce the return strokes. The elements 100, 101 are moved towards and away from each other as follows. The element 100 is attached to a nut secured against rotation, the connection being a rod 116 extending along the machine. The nut is carried on a screwed shaft 120 having opposite ratchet-wheels 129, 130 attached. The ratchetwheels 129, 130 are revolved by pawls 131, 132 oscillated by a cam 137 on the shaft 30 through a roller 136 and lever 133, Fig. 8. Fingers 146, 147 are operated through a shaft 149 and bellcrank 150 by a projection 153a carried on one of the machine's " automatic " shafts 72, and these fingers engage one or other of the pawls 131, 132, and cause motion of the shaft 120 in one direction or the other. The means for moving the element 101 is identical and is controlled by a cam 167 on the shaft 30. Operation.-Upon the completion of the leg portion, the roller on the cam controlling normal pressing movement of the needle-bar is shifted to the idle position by a fork 39, the fork 39 being attached to a rod 40 controlled through levers 211, 213, 215 by projections 210a, 210b carried on a lower " automatic " shaft 73. Projections 223a on the shaft 73 also operate, through levers 222, 221, 220, a shaft 219 carrying a fork 218 which shifts the roller 110 into engagement with the cam 111. Rollers are shifted into engagement with the cams 137, 167 by forks 177, 178, the forks being carried on spring-loaded rods 179, 180 which are moved through stops 187, 188 by further spring- loaded rods 191, 192. The rods 191, 192 are operated by projections on the auxiliary pattern chain 95 through connections 197, 198. The elements 100, 101 are shifted outwardly, say, two needles at alternate courses, thread carriers 50, 51 being correspondingly moved, to form the heel cheeks AEB, DCF, Fig. 16. The elements and yarn guides are then moved inwardly at the same or at a different rate to form heel cheeks EGB, CHF. Courses of normal knitting may be interposed between the cheeks AEB, DCF and EGB, CHF. The " automatic " shafts 72, 73 are operated from cams on the shaft 30 by ratchet-wheels and pawls, the operation being controlled by the main pattern chain. Specification 619,490 is referred to.

Abstract: 239,730. Freeman, L. G. Oct. 21, 1924. Preparing lasted boots for sewing.-A tack-pulling machine of the kind wherein a tack fork is caused to move in a closed path of circular or oval form is provided with an adjustable guard to protect the boot upper and with means for lubricating the working parts. A shaft 22 in the head of the machine is rotated by a belt 25 from a driven shaft 11, Fig. 1. An eccentric 36, Fig. 2 on the end of the shaft 22 is connected to the rear end of a bar 32 which carries a tack fork 48, and which is connected by a link 43 to a bar 42, so that rotation of the shaft 22 imparts a circular motion to the forward end of the bar 32 and to the tack fork. A member 27 on the shaft 22 dips into oil in a reservoir 17 in the machine head, so that as the shaft 22 rotates oil is splashed forwardly on to the bar 32 and its bearings, but is prevented from reaching and soiling the boot by shields 46, 71. The tack fork is adjustably held in the forward end of the bar 32 and has several parallel tapered teeth. A guard 62 is mounted for vertical adjustment in a clamp 57 on an arm 52 horizontally adjustable on the machine head, and a shield 59 protects the operat- or from the thrown out tacks. The guard 62 is formed with a side ring 63 to protect the upper from damage and an extended wing 64 which functions to hold down the upper whilst a tack is being withdrawn. In a modified form, the wing 64 may be adjustable on the guard and the latter may carry in its lower edge an antifriction roller. The forward edge of the tack fork preferably lies at an angle to the plane in which it moves, and its shank is serrated to grip similar serrations in the end of the bar 32. Another modified form of guard 82, Fig. 10, is adjustably mounted on a holder 80. The forward end of the guard is curved to follow the path of the tack fork 48 and the guard is provided with wings 84, 85 and a transverse V-shaped slot 86 to accommodate a tack.

Abstract: 788,446. Coking Coal. KRUPPA, W. J., and RINCKOFF, J. B. Aug. 30, 1954, No. 25132/54. Class 55 (1). In a process for producing coke from badly swelling and coking coals pulverized coal is entrained in an air stream and passed through a heating zone to heat it to a temperature within the plastic range of the coal, e.g. between 500-800‹ F., for a controlled brief period of time, e.g. between 10-15 seconds, followed by cooling to a temperature at which oxidation is inhibited and mixing the oxidized coal with a binder and carbonizing formed units of the mixture. The air stream may have a velocity of the order of 1000 ft. per minute and the coal is preferably predried before the oxidation to a moisture content of 1 per cent. The binder for the oxidized coal may be a coal tar pitch to which may be added sulphuric acid, a wetting agent, waste sulphite liquor, amylaceous and saccharogenic compounds. The formed units are carbonized by contact with a hot inert gas and the heat input is such that the temperature increases at 2.5-5.0‹ C. per minute up to 500‹ C. and thereafter at 0.75-1.25‹ C. per minute to the final coking temperature, e.g. 800-1000‹ C. In Fig. 1A, coal fed in at 1 and crushed in a mill 2 is entrained in a stream of hot gas from a gas-fired furnace 3 and passed by conduit 6 to a separator 7, dried coal being collected in a bin 17. Gases from the separator 7 are in part recycled and in part passed to a stack 15 through a separator 13, separated solids from separator 13 being returned to the conduit 6. Dried coal from bin 17 is entrained in an air stream and passed through an externally heated coil 29, the oxidized coal and air mixture being then cooled in a cooling coil 27 and separated in a separator,37. The oxidized coal is mixed with the binder and briquetted, the briquettes being then heated in a progressive manner by direct contact with hot gas. The gas and tar obtained from the carbonization may be used in the process as heating gas and as binder respectively.

Abstract: 912,216. Carburetters; admission passages; mixing air and gas. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. July 19, 1960 [July 21, 1959], No. 25173/60. Classes 7(2) and 7(3) Two streams of combustion supporting substances in variable proportions are simultaneously admitted to the cylinder the richer of which is a carburetted mixture directed towards the sparking plug the regulation of the respective proportions of these two streams conditioning the aggregate richness of the mixture and the degree of heterogeneity thereof and permitting operation with a poor mixture and subsequent return as desired to a feeding with rich aggregate mixture necessary to obtain maximum power. In Fig. 3 the carburetter C supplies very rich mixture. The valve A serves to regulate the delivery of rich mixture in the pipe Cr and the valve B serves to regulate the supply of air through the pipe Cp. The opening of the valve D not commencing until after complete opening of the valves A and B the opening of the three valves may be readily effected by a single control. The minimum admissible aggregate richness was obtained corresponding to introduction of the total quantity of fuel in the form of a very rich mixture (richness at least equal to 5 and preferably being between 20 and 50) by the pipe Cr while the pipe Cp admits only air. In the majority of cases it is desirable not to exceed a richness of the order of 100. Fig. 2 shows a cross-section of the cylinder head of a four cylinder engine. Each pipe Cr for the richer mixture has its end directed towards the associated sparking plug B. It is possible to substitute for the carburetter a fuel injector disposed ahead of the connecting passage. The valves in the admission pipes may be situated ahead of or below the connecting passage and they are preferably controlled in synchronism. A nozzle or throttling device may be disposed in the air admission pipe ahead of the connecting passage. The fuel may be either a gas for example natural gas or a liquid such as petrol or even kerosene if the engine comprises a sufficiently efficient heating device.

Abstract: 317,769. Kueneman, J. R. Aug. 21, 1928, [Convention date]. Ball and like mills.-In a grinding mill comprising a horizontally disposed grinding chamber having a feed opening adjacent one end and delivery means at the opposite end, means are provided to constantly urge the material in the grinding chamber toward the feed end thereof, the finer particles of the material working out at the delivery end of the mill. The drum 6, Fig. 1, is lined with helical strips 23 one edge of each of which is provided with a recessed rib 22, the plain edge of the adjoining strip fitting into the recess together with a key 27 which wedges the strips together. The ends 25 of the strips engage in annular recessed portions 26 of the end plates 8, 9. The rotation of the drum 6 causes the ribs 22 to urge continuously the balls and large particles of unground material toward the end plate 8 which acts as a grinding surface for the material entering at 17. The end plate 9, through which the ground material is discharged, is provided with perfora,- tions 18 and oversize particles passing through the perforations are retained on a lipped ring 29 which is provided with outwardly flaring slots 33 through which the ground material passes to the screen 28. A conical member 37 is supported by radial ribs 38 from the ring 29 and the apex of the cone projects into a central perforation in the end plate 9 so that oversize particles from the screen 28 and ring 29 fall on the cone and are returned to the mill. A spray 39 may be used to clear the screen and cone during wetgrinding. When unsized material such as slimes is desired the ground material from the chamber 47, Fig. 5, passes through the perforations in the end plate 45 on to spiral ribs 41 which retain the heavier particles and drop them on the cone 44 for return to the mill. The pulp passes over further spiral ribs 42 in the discharge orifice 43 from which the heavier particles are wormed back to the ribs 41 for return to the mill. A water spray 49 may be used to clean the cone 44. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement whereby the oversize return unit may be adapted to existing mills as shown in Fig. 6 (Cancelled) in which an annular passage 51 is provided for the discharge from the grinding chamber 52 on to a lipped ring 53 and screen which are similar to that shown in Fig. 1. The oversize particles are raised by the vanes 54 and dropped on to the cone 56 for return to the grinding chamber through a passage 57. This subject-matter does not appear in the Specification as accepted.
