Filed: 1933-12-05
Abstract: 417,743. Sporting guns. GARWOOD, G. T., Tudor Cottage, Lyndhurst, Hampshire. Dec. 5, 1933, No. 34120. [Class 119.] A rebounding firing-lock mechanism for ejecting or non-ejecting drop-down guns comprises a tumbler t pivoted at b, a sear s, a mainspring h, and a cocking lever c, the cocking lever being pivoted at a and having a projection h<1> in the knuckle of the action-body limited by a stop f<1>, and the mainspring having two limbs, one bearing on the tumbler and the other on a stud r so that both tumbler and cocking lever are urged in the same direction by the spring. When a shot is fired by the release of the sear from the tumbler, a nose n on the tumbler strikes a toe e on the cocking lever and this makes the tumbler rebound slightly ; at the same time, the spring h slides forward and projects into the knuckle where it may serve to actuate an ejecting device. When the barrel is unlocked, it is turned down by the cocking lever under the influence of the mainspring, and at the same time the toe e of the cocking lever turns the tumbler back into engagement with the sear s. Finally, the reclosing of the gun forces the cocking lever back and recompresses the mainspring. Specification 372,035 is referred to.

Title: Railway sleepers and other articles made of pre-stressed reinforced concrete, and a method of and apparatus for manufacturing such parts
IPC: E01B3/34
Filed: 1947-12-24
Abstract: 629,872. Pre-stressed reinforced concrete articles, e.g. poles, sleepers. FREYSSINET, E. Dec. 24, 1947, No. 34176. Convention date, Feb. 14, 1942. [Classes 20(i)and 20(iv)]  [Also in Group XXX] Pre-stressed concrete articles, especially short articles, e.g. small poles, railway sleepers, are made by forming the body in two parts separated by a slit and joined by the reinforcements, pulling the two portions apart to tension the reinforcement and widen the slit, and arranging a wedge, preferably of caulked mortar, in the slit. As shown a sleeper is formed in a mould 1, which is divided by a partition 2, by placing a block b, b 1  at each end winding reinforcements a, a 1  of steel of high elastic limit and filling the mould with concrete. Each layer a, a 1  of reinforcement is formed from a wire the two ends d, e of which hook together, and between the points g, g 1  the wire is covered with bitumen and fitted with gutters 3 at the curves to permit movement during stretching. This arrangement of reinforcement permits of reducing the section of the sleeper in the middle to reduce the weight. When set the sleeper is gripped between pairs of jaws 15 15, 16 16 by means of bolts 17 and nuts 18, when slipping is prevented by the sloping sides of the sleeper and by the interengaging grooves 19, and the whole is placed in two cages 20, 21 which are moved apart by jacks 22. Wedges 25 are placed between the jaws 15, 16 and the inclined edges 23, 24 of the cages with lead plates 35 between and keys  36 prevent the wedges from slipping. The cylinders of the jacks are adjustable vertically by bolts 29 and nuts 28 and are held in the cage by screws 27. When the required tension is  applied, and the gap between the sleeper parts widened, the partition 2 is removed, and the gap filled with a rich dry cement mortar by caulking with a hammer and surrounded by a bending device with uprights 31 adjustably connected by screwed rods 32 and nuts 33 and with horizontal wedge members 34 between. The jacks &c. are then removed. The concrete blocks 6, 6 1  are formed in two sections 4 separated by a slit 7 in a frame, in the inner face of which the reinforcement 5 has been wound, with ends 5a, 5b anchored at top and bottom respectively, and a hoop of steel wire containing a conical froming placed in each half when the concrete has set. Wedges 9 are driven between liners 13 into cavities 8 at the ends of the slit 7 to force the block halves apart and tension the reinforcement, and the slit 7 filled by caulking with mortar and the wedges removed. Alternatively the reinforcement may be fitted to the cast blocks and then tensioned. When the sleeper is finished elements C of dry hard wood &c. are inserted in the frusto-conical cavities, formed in the block halves, and serve to receive the coach screws &c. The sleeper may be curved in the vertical plane as shown in Fig. 1.

Filed: 1927-12-21
Abstract: 294,430. Walker (Blackburn), Ltd., P., and Walker, H. D. Dec. 21, 1927. Jacquards.-In cross border jacquards, the T- levers C for operating the body and border cylinders A, B are mounted on pendant arms D, one of which has a roller or bowl d' entering a cam' groove in a cam E. The pendent arms D are connected by links, d to arms d<1> on a cross shaft d<2>, whereby they are caused to move in unison. A catch f controlled by a pattern chain F, which is intermittently rotated under the control of two strong indicating needles G, G<1> operated by the respective cylinders A, B can turn the cam by operating a star wheel e<1> on its shaft, thus shifting the pendent arms D and T-levers 0 and causing a change from one cylinder to the other. The cam groove is shaped to bring the pendent lever D it controls slowly to rest in its two positions. The star wheel is controlled by two spring- pressed plungers e<2> and the catch f is operated by an arm f<1> on the usual rocking shaft operated from the top shaft of the loom by the usual crank and connecting rod and operating the T-levers C by lever mechanism. The pattern chain has rollers f<2> for raising the catch f clear of the star wheel e<1>, but also certain axles f<3> free of rollers which allow the catch to engage. The indicating needles G, G<1> are connected by a link g so as to move. in unison, and special holes are formed in the cylinder to receive these needles. The chain F can be intermittently rotated by means of a catch f<4>, but when one or the other needles G, G<1> is pressed back a notched part of the needle G operates a finger f<8> and a finger f<6> is moved into a position in front of the catch f<4>, which then moves past its star wheel f<5> without operating it. If, however, the needles G, G<1> remain stationary, the catch f' operates the wheel. The hooks H connecting the needles a, b are bent where they engage their respective bars h<1>, to prevent these hooks from' turning and lifting during the working of the jacquard.

The position of the valve element 24 is controlled by an engine driven centrifugal governor 10 to selectively connect a chamber 15 of the servo 1 with a vacuum chamber 19 for clutch disengagement or with an atmospheric chamber 22 for clutch engagement. At low engine speeds the valve element 24 is moved left to connect the chamber 15 through ducts 40, 16 with the vacuum chamber 19 for clutch disengagement. As engine speed rises the valve element 24 is moved right to disconnect the chamber 15 from the vacuum chamber 19 and to connect it to the atmospheric chamber 22 for clutch engagement. The compression of the spring 41 is dependent upon the position of the servo piston 12 and provides a force on the valve element 24 proportional to clutch engagement. During ratio shift in a following change speed gear an electromagnet 4 is energized by closing a switch 37 associated with a gear shift lever 38 to move the valve element 24 left for clutch disengagement. As shown the servo piston 12 is connected by a lever 42 and hydraulic linkage 43, 44 with a clutch actuating lever 33. In Fig. 1 (not shown) the servo piston 12 is mechanically linked to the clutch actuating lever.
