Title: Improvements in or relating to centrifugal friction clutches
Inventor: NEWTON NOEL BANNER
IPC: F16D43/12
Filed: 1955-09-13
Abstract: 843,095. Centrifugal clutches. NEWTON & BENNETT Ltd. Sept. 13, 1956 [Sept. 13, 1955; Oct. 22 1955 (2),], Nos. 26178/55, 30251/55 and 30252/55. Class 80 (2). In a friction clutch having a plurality of centrifugal masses operating a presser plate through clutch springs, the springs and the masses are arranged such that the springs act both as clutch springs and hold-off springs. A flywheel 10 carries a fixed plate 11 secured thereto by studs 12, the plate having three sets of brackets 15 carrying pivot pins 16 for levers 17 having centrifugal masses 19 attached thereto. At its inner end each lever 17 has a pivot pin 20 carried by brackets 21 attached to a spring plate 22. The levers 17 are ot channel section and have slidably mounted therein fulcrum plates 17a having projections 17b each side of a central slot, the plates being inwardly urged by a light spring (not shown). A presser plate 25 has studs 34 having collars 35 engaging the projections 17b, the plates 25 and 22 being urged apart by clutch springs 26 (not shown) passing through clearance holes in the fixed plate 11. Clutch withdrawal levers 28, actuated by a ring 30, are pivoted on the fixed plate 11 and engage collars 31 on studs 33 secured to the presser plate. In operation, when the flywheel 10 is stationary, the clutch springs act with differential leverage about the pivot 16 through pivot 20 and fulcrum 176 to cause withdrawal of the presser plate 25 and thus disengage the clutch friction plate 23. As the flywheel rotates and the masses 18 start to move outwards, the plate 22 is moved towards the flywheel, while the stud 34 and collar 35 allow the presser plate 25 to move a lesser distance. When the presser plate engages the friction plate 23, the fulcrum 176 leaves the collar 35 and the whole of the centrifugal face is transmitted to the presser plate through the clutch springs. Above a predetermined speed the masses 18 engage the outer surface of holes in the rim of the flywheel to assure balance of the rotating assembly. Operation of the withdrawal levers 28 with the clutch stationary moves the collars 35 away from the fulcrums 176 and allows the light springs to move the plates 17a inwards, release of the ring 30 then engages the clutch for towed starts. Rotation of the clutch in this condition causes the plates 17a to resume their normal position under centrifugal force and the clutch functions as before. In a modification, the fixed plate is made as a die-casting or pressing in three separate pieces to facilitate production, and the weight levers are channel section pressings. In a further modification the spring plate is omitted and the mass levers form abutments for the outer ends of the clutch springs. Specification 843,096 is referred to.

Title: Method of and apparatus for agglomerating or briquetting fuels
IPC: B30B11/12
Filed: 1938-09-14
Abstract: 522,515. Moulding briquettes ; switching systems. V. H. A. SYNDICATE, Ltd., and HOESTEMBERGHE, C. VAN. Sept. 14, 1938, No. 26836. [Class 87 (ii)] [Also in Group XXXV] A process for briquetting fuels comprises feeding the residue from a low-temperature distillation process consisting of de-gasified non- porous carbonaceous products in a plastic condition intermixed with a dry carbonaceous product rendered porous by the expulsion of its volatile constituents and also containing extraneous porous solid carbonaceous matter such as coke added to the bituminous fuel prior to distillation, to a zone in which it is subjected to progressively-increasing pressure and is kneaded intensively, the mass being then filled successsively into moulds and allowed to remain there for a period to complete the inter-penetration of non-porous into porous constituents. In the construction shown, a hopper 1, adapted to receive the fuel which has undergone low temperature distillation, is integral with a receptacle 3 enclosing a screw conveyer 4. The fuel is kneaded and pressed by the conveyer and is then forced into one of a number of cavities carried by a rotary table 16. The table 16 and the conveyer 4 are operated alternately by means of electro-magnetic clutches 11, 12, the table moving step by step to present each cavity in turn into position to receive fuel from the conveyer. The table is provided with a toothed wheel 17 adapted to be engaged by a crank 19 carrying a bolt 33 for locking the table between movements. The crank 19 is driven through gearing by the clutch 12 and the conveyer 4 is driven by means of the clutch 11. When a cavity in the table is sufficiently filled, the resistance to the movement of the screw produces excessive current through the motor 14, whereby a relay 34 is energized. The armature of the relay closes a circuit for a relay 35 which closes the contacts to complete a circuit for the clutch 12. The table 16 is thereby given a step forward through operation of the crank 19. In the meantime a relay 36 is de-energized so that its contacts fall back to open the circuit for the clutch 11 which operates the screw conveyer 4. After the table 16 has been moved one step a contact breaker 38 is opened by a cam 37 whereby the circuit of the clutch 12 is opened and the circuit of the clutch 11 is closed, so that the conveyer is again operative. A recess in the cam 37 allows the contacts 38 to close again whereby the operations may be repeated. The material is forced from the cavities in the table 16 by means of a spring-pressed ram operated by a cam.
