Abstract: 525,245. Screw conveyers. FITCH, H. H. Feb. 21, 1939, No. 5813. [Class 78 (i)] In an underfeed stoker fuel is delivered from a bin to a furnace by a screw conveyer co-operating with means below the furnace whereby the fuel is forced upwardly into the furnace. As shown, the fuel feeding conveyer is tapered and co-operates with a tapered screw conveyer of opposite hand in such a manner that the fuel is forced upwards into the furnace by the inner ends of the opposed screw threads. In one construction a shaft 47, Fig. 2, carrying screws 38, 48 of opposite hand extends below the intake 12 of a retort 11 into a fuel supply bin 18. The screw 38 passes through a conduit composed of telescopic members 39, 25 which can be adjusted with respect to the furnace and bin respectively. One end of the shaft 47 is formed as a polygonal socket 34 which receives a similarly shaped tongue 33 formed on a rotatable member 31 mounted in a support 28 on the floor or wall of the bin. The other end of the shaft is formed as a polygon 82 and is received in a coupling 83. The polygonal end 60 of a driving shaft 58 is received also by this coupling. The conduit 43 surrounding the part 48 of the screw is mounted telescopically in the lower part of the furnace and is bolted to a sleeve 70 secured to the gear casing. A plate 76 secured between the flanges of the sleeves carries a sealing structure 79 which supports an enlargement 80 of the shaft 47. A cone thrust-bearing 87 is placed between the plate 76 and a collar 85 which is secured to the coupling 83 and is seated in a recess 81 in the shaft. The tube 70 is filled with grease. In another construction the socketed end 244, Fig. 4, of the screw 243 is connected to one end of a tube 249 by a pin 247. The other end of the tube 249 receives a shaft 259 and is detachably connected thereto by a bolt 270. The socketed end 260 of the shaft 259 is slotted to receive a pin 254 on a driving shaft 252. The housing 253 is detachably secured to the gear casing 251 and is also secured to an arm 264 which is part of the motor base. A sleeve 266 is bolted to the housing 253 and receives the tube 241. A set screw 268 mounted in the sleeve serves as a stop for the end of the tube. On the other side of the furnace is arranged a tube 273, Fig. 5, for conveying the fuel from the bin. This tube is in axial alignment with the tube 241 and is supported in the opening 281 of the bin by a, pair of complementary members 285. A collar type bearing 282 is secured to the plate 277 and carries pivot screws 288 which engage aligned recesses 290 in the spherical surface of the members 285. In the construction shown in Fig. 8, the bin portion of the conveyer carries flights 343b terminating at 343b<SP>1</SP>, and the flights 343a of the furnace portion terminate at 343a<SP>1</SP>. Tubes 373, 376 containing these parts are connected by a sleeve 375. A spiral strip 301 carrying a flight 302 receives the shafts 386a, 386b and is secured thereto by set screws 308.

A well drilling apparatus to be lowered in a borehole on a cable comprises a clamp member A for locking the casing of the apparatus in the borehole, an electric motor B, and an automatic feed C for a rotary drill shaft and bit D. When the feed C comes to the end of its stroke, the clamp A is released and the apparatus hoisted out of the borehole by a cable. The drill D is removed and replaced by an internally helically finned extractor, the assembly again lowered and the extractor rotated to pick up the spoil when the assembly is again removed and the extractor replaced by the drill. The clamp has, pairs of fins which are forced into the wall of the borehole to prevent rotation or axial displacement of the apparatus casing. The shaft U of the electric motor B is connected directly to the drill shaft D and at the same time rotates, through gearing X, B1, A1, T an externally threaded nut Q which runs down a thread R on the inside of the apparatus casing S carrying the motor B and drill D with it. To prevent the motor B from rotating it slides in vertical grooves cut in the thread R. The gear X may be replaced to alter the rate of advancement of the nut Q. In a modification, when an auger bit is used, the extractor may be formed around the drill shaft and rotate with it and the bit, the assembly being removed from the borehole each time the extractor is full. The provisional Specification also states that the motor may be driven by steam, water, or air.

Abstract: 1,176,132. Rolling mill. UNITED ENG. & FOUNDRY CO. 24 Jan., 1967 [10 Feb., 1966], No. 5974/66. Heading B3M. [Also in Division G3] A rolling mill has variable prestressing means to keep the gap constant which comprises a piston cylinder assembly 23 which is activated to oppose the separating force of the work between the rolls 19, 20 by a load cell 26 between the upper chock 14 and the housing 10. The work rolls 19, 20 are mounted in chocks 17, 18 mounted in openings 16 in the back-up chocks 14, 15. The chocks 14, 15, 17, 18 are urged apart by roll balance piston cylinder assemblies 21, 22. The gap is initially set by screw down means comprising rods 31, threaded in nuts 33 in the housing and abutting compression bars, 34 which are positioned in parallel channels 27 in the upper chock and extend to the lower chock. The upper ends of the rods 31 are driven in synchronism by a motor 35. To make the parts of the mill associated with the prestressing cylinder 23 readily yieldable each of the lower chocks 15 is provided with spring 40 and plunger 41 mechanism against which the compression bars 34 abuts. As the working load P on the rolls 19, 20 increases as indicated by the load cell 26 the prestressing force F in the assembly 23 is increased, the force F always being greater than the force P. Details of the inter-relationship between the moduli of the mill parts and the applied forces are given. The signal from the load cell 26 is supplied to a multiplying amplifier (58), Fig. 4 (not shown), where it is combined with a signal (Y + 1) from a series of amplifiers supplied with signals M R , M c  represent elastic constants of the mill from manually adjustable potentiometers (46), (52). The signal M R  is corrected for roll radius and strip width.

Abstract: 904,322. Dobbies. HINDLE, T. Jan. 24, 1961 [Feb. 20, 1960], No. 6064/60. Class 142 (2). A dobby has alternate jack levers 1, 2 operated by upper and lower crank gears 12, 13, respectively. Considering the upper half of Fig. 6, a continuously reciprocating knife 44 moves a push-rod 38 (if selected) to raise a cam lever 28, which, by tracks 24, slides a segment gear 20 lengthwise on a continuously-rotating shaft 18, to engage it with the crank gear 12 to move the jack lever 1 to the position occupied by jack lever 2. Selector mechanism.-As the jack lever 1 moves, it moves a lever 46, connected to a floating lever F, to either of two positions 50, 51. A bowl and tube pattern chain 60 also move the other end floating lever F to either of two positions 52, 53. With the parts as in Fig. 6, the pattern chain has not raised the floating lever F which lies obliquely and no shed-change occurs. When a bowl raises the lever F to position 52 so that it lies horizontally the push-rod 38 is brought into the path of knife 44, the jack lever 1 is moved and the other end of the lever F is lowered to 51 so that it again lies obliquely and the push-rod 38 is moved from the knife 44. If at the next pattern change a bowl retains the lever F lifted obliquely to 52 no change occurs, but if a pattern tube lowers the lever F horizontally to 53 change occurs. In Fig. 5 (not shown), the push-rods are actuated by solenoids in an electrical circuit. Manual operating means are provided, the throw of the crank gears may be varied and the ends of the pushrods may be shaped to aid retention on the knives.
