Title: Improvements in or relating to apparatus for driving a dobby or a jacquard-mechanism
IPC: D03C1/16
Filed: 1927-02-15
Abstract: 271,412. Staubli, H., Staubli, H., Staubli, R., and Staubli, H., (trading as Staubli & Co., Geb.). May 18, 1926, [Convention date]. Dobbies; jacquards.-Relates to means for driving dobbies and jacquards by power or by hand as required. The shaft 1, Fig. 2, carrying cams 2 for driving the knives of the dobby has a bevel wheel 4 in mesh with a wheel 5 loose on a shaft 6, Fig. 1, driven from the upper or lower shaft of the loom. During normal working of the loom, the wheel 5 is coupled to the shaft 6 by a clutch device comprising a clutch member 26 fast on the shaft and in permanent engagement with a, sliding clutch element 25 having one or more clutch claws 28, which are held in engagement with corresponding claws on the wheel 5 by a spring 27. The clutch element 25 is connected by a fork 24 to a bell-crank lever 22 pivoted at 23 and engaged by a lever 19 geared to an arm 17, Fig. 2, connected to a bent rod 14 engaging a sleeve slidable on a shaft 9. The sleeve carries a spring-controlled lever 13 carrying a pin 12 for engagement in one of two grooves 11 in the shaft 9, and a wheel 8 capable of gearing with a wheel 7 on the cam shaft 1. When it is desired to operate the dobby by hand, for example for finding a broken pick, the lever 13 is depressed and the sleeve is moved to the left by a crank 10, thereby allowing the pin 12 to move into the left hand groove 11 and causing the wheels 7, 8 to mesh, the rod 14 through the mechanism described causing the clutch element 25 to be moved out of engagement with the wheel 5. The dobby can then be operated by rotating the crank 10. To cause the dobby to be' again driven by power, the parts are moved 'again into the position shown, the claw parts 28 preventing that from being done until the shaft 1 is in the same position relative to the driving shaft 6 that it occupied before the dobby was operated by the crank 10. The correct position may be found by operating the lever 10 backwards or forwards until the' claws. 28 come into engagement by the action of the spring 27, the sleeve then being free to move on the shaft 9 to the right, as shown.

Title: Improvements in combined antifriction and friction bearings
IPC: F16C21/00
Filed: 1921-01-10
Abstract: 175,655. Florell, Y. March 8, 1919, [Convention date]. Ball, roller, and cylindrical journal bearings.- In a combined antifriction and friction bearing a material is inserted between two bearing parts which changes in form when the bearing runs hot and causes a movement of one of the parts such that the antifriction bearing is run out of action and the friction bearing comes into action. In a wagon axle-box, a shaft 1 carries a sleeve bearing 3 with Babbitt-metal lining 2. The sleeve 3, which is divided axially, has a conical outer surface carrying the inner race-ring of the antifriction bearing 4, which is clamped in position by a sleeve 5 and screw 6. The conical surface may be replaced by a shoulder. The friction bearing projects axially beyond the antifriction bearing and is visible beyond the casing 7, so that it may be seen which of the two bearings is in action. The casing 7 rests on the antifriction bearing through a layer 10 of a fusible material, so that if the antifriction bearing runs hot and the layer 10 melts, or the antifriction bearing becomes deformed, the casing moves so that the sides 13, 14 move into engagement with the friction bearing and the whole acts as a friction bearing. Packing 8, 9 is arranged between the sides 13, 14 and the friction bearing. The sleeve 3 has chambers 11, 12 for lubricant communicating with the friction surface.

Title: Improvements in emulsions of bituminous material
IPC: C08L95/00
Filed: 1925-02-23
Abstract: 252,258. Hutton, H. W., and Fulton, C. W. Feb. 23, 1925. No Patent granted (Sealing fee not paid). Emulsions, making. - Bituminous emulsions are prepared by adding separately to liquid or molten bituminous material a small proportion of a sulphonated oil or fat which has not been neutralized, even in part, and an aqueous solution of alkali or ammonia in quantity sufficient to neutralize the sulphonated product. Preferably the sulphonated oil or fat is mixed with the bituminous material and the neutralizing solution thereafter incorporated, but alternatively the neutralizing solution may be mixed with the bituminous material and the sulphonated oil or fat then added. According to an example, concentrated sulphuric acid is introduced slowly with stirring into a tank containing the oil or fat, the amount of acid being about 25 per cent by weight of the oil or fat. The temperature is kept below 80-90‹ F. during mixing, and after 5-24 hours the product is washed with a neutral salt solution or water or both and separated. The sulphonated oil or fat is incorporated with molten bitumen in the proportion of 1-5 per cent of the bitumen, and 14-28 per cent of caustic soda, reckoned on the sulphonation product, is then added in the form of a 2 per cent solution, whereafter a final addition of hot water is made. Instead of caustic soda the neutralizing agent may be ammonia or caustic potash, sodium or potassium carbonate, or the silicate or bora.te of an alkali metal or of ammonium. Specification 236,641 is referred to.

Abstract: 914,994. Fluid-pressure brakes. CAM GEARS Ltd. Feb. 17, 1959 [Feb. 17, 1958], No. 5140/58. Class 103 (1). [Also in Group XXIX] In a fluid pressure system including two pressure utilization means, e.g. power-assisted steering means 17 and powerassisted braking means 18, a valve means 1 proportions the flow from the pump 16 to the two means 17, 18. The valve 1 comprises a housing 2 having a passage 3 with inlet 4 and outlet 5. A passage 12 with an outlet 14 opens into the passage 3 and the opening is controlled by a spring-loaded valve member 7 slidable in an enlarged bore 6 of the passage 3. An orifice 11 in the valve member 7 allows a continuous flow of fluid to the braking means 18. In operation, the valve member 7 takes up an equilibrium position determined by the strength of the spring 10 and by the back pressure in the passages 3 and 12, caused by the means 17 and 18. In another example the valve housing 2 is integral with the master cylinder of the braking means comprising a tubular casing 19 closed by plugs 23, 24 and containing a piston 20, 35. A spool 21 is axially slidable within the bore 31 of the piston 20, 35 and has a head 44 which co-operates with a seat 34. Under idling conditions, fluid from the pump passes through the valve 1 and acts on the face 63 of the piston 20, 35 which moves away from the plug 23. Fluid passes to the space 52 which is connected via ports 51, passage 49, bore 48, recess 46, space 45, openings 53 to the annular space 54 which is connected through port 56 to a reservoir (not shown). In operation, the spool 21 is moved by the element 59 to cause the head 44 to engage the seat 34 and the pressure builds up on the near face of the piston 20.
