Title: Improvements in and relating to processes and apparatus for the production of margarine and like edible fats
IPC: A23D7/05
Filed: 1926-04-26
Abstract: 274,949. Jirotka, B. April 26, 1926. Butter substitutes.-In connection with the manufacture of margarine &c. wherein the mass or emulsion is passed between cooled rollers or bands, these members are given different peripheral speeds so that where they contact they exert not only a pressing action but also a rubbing and knead. ing action upon the mass. Prior to this treatment the mass is disintegrated by spraying, and this disintegration may be repeated with simultaneous cooling. As shown in Fig. 1, the mass is sprayed by a perforated tube d on to a cooling and distributing plate or screen c, and then falls on to oppositely-turning cooling and kneading rollers a rotating at different speeds. Scrapers f remove the films from the rollers and the fat then falls on to lower rollers b where the operation is repeated. A single pair of rollers such as a may, however, be used; or the rollers may be replaced by horizontal or angularly arranged endless bands on cooled pulleys, and. cooling vessels may be arranged within the bands between the pulleys. With the apparatus shown in Fig. 5 a pipe p conducts the margarine mass from the emulsifier or the granulating apparatus to a channel d which is perforated to effect a distribution over the length and breadth of the screen c, and wooden rollers r<1>, r<2> conduct the mass on to the lower cooled rollers a<1>. a<2>. Or the rollers r<2> may be replaced by a conveyor carrying the mass to rollers a<2> disposed some distance to one side of the other rollers.

Title: Improvements in or relating to machines for grinding the main bearing pins and crank pins of crankshafts
IPC: B24B5/42
Filed: 1949-04-26
Abstract: 674,065. Grinding crankshaft pins. MUSYL, R. April 26, 1949 [June 10, 1948], No. 11077/49. Class 60. A device for grinding the main bearing pins and crank pins of a crankshaft 2 which during the grinding process is revolved about the main bearing axis and in which device the grinding wheel axis and the axis of the pin to be machined perform congruent motions is characterized in that the congruence of the motions of both latter axes is achieved by the grinding wheel being mounted for rotation in bearings rotatable with the same eccentricity as that of the pin to be machined and which bearings are rotated in synchronism and in phase with the rotation of the pin, the congruence of the motions being obtained by adjustment of means permitting continuous variation between predetermined limits of the eccentricity of the grinding wheel centre so that this eccentricity equals the crank throw. The crankshaft 2, Fig. 2, is rotated at uniform circumferential velocity in contact with the grinding wheel 4 which is eccentrically mounted in a sleeve 6 mounted eccentrically in a drum 7 rotatable in a support 13; a motor 8 drives the drum through gearing 9, 10 and the sleeve and drum are then locked together. For adjusting the eccentricity of the grinding wheel spindle, the sleeve and drum are coupled by planetary gearing 16, 17, 18, 19, the gear 16 being rotatable relatively to the drum, the gears 17, 18 being journalled in the drum, and the gear 19 formed on the sleeve. Adjustment of the eccentricity is effected by locking the gear 16 by a pin 12, disengaging the lock between the sleeve and drum, and then rotating the drum by a hand-wheel 14. After this adjustment, release of the gear 16, and re-engagement of the lock between the sleeve and drum, the handwheel 14 may be turned to adjust the drum relatively to the workpiece without affecting the eccentricity. During operation of the grinding wheel in an orbital path by the motor 8, it is also rotated by a motor 22, Fig. 4, carried by the support 13 and acting through two belt drives 23, 24, the intermediate pulley 27 being mounted at the junction of two pivotally-connected arms 28, 29 which are pivoted, respectively, on the motor shaft and grinding wheel spindle 5. To compensate for the weight of the rotating grind-. ing wheel, a lever 30, Fig. 6, carrying the grinding wheel spindle 5 is connected at its upper end to a double lever 31 mounted on the support 13; a compression spring 37 acts upon the second arm of the lever 31 at a variable distance from the pivot of the lever. The crankshaft may be mounted between a headstock and tailstock 40 on a bed 38 as shown in Fig. 9, and the undersurface of the support 13 is mounted on a surface inclined downwardly towards the crankshaft. If desired, a machine may be constructed to operate on four crankshafts simultaneously, a grinding wheel together with its support 13 being provided for each crankshaft.

A rope 13 is attached to the drum, and after making a few turns round it, the end of the rope is brought to a position convenient for operation by the attendant of the plough. Upon pulling the rope, the drum is rotated and the quadrant 2 swung about its pivot 3, forcing the land wheel down relatively to the machine frame. The quadrant is retained in its adjusted position by a pawl 15, which engages teeth on the quadrant, and which may be lifted by the pull on the rope 13. In a modification suitable for heavy ploughs, the rope 13, after leaving the drum 12 and passing over a pulley 18 which is adjustable in position and which operates the retaining-pawl, passes over guide-pulleys 21, and is then given a few turns round a drum 19 secured to the hub of the land wheel. On tightening the rope, it is frictionally engaged by the rotating drum, and thus assistance is given in moving the quadrant. The drum 19 may be free to rotate on the hub, but arranged to be clutched to it by the depression of an outwardly spring-pressed plunger mounted in the drum and adapted to be engaged and pressed downwards into a recess in the rotating hub, by the rope 13 when this is tightened. The device may be applied to agricultural implements and vehicles generally.
