摘要： 489,663. Hydraulic rams ; lifting- jacks. CLAYTON DEWANDRE CO., Ltd., CALLA, W. M., and WILLETT, S. E. Feb. 1, 1937, No. 2905. [Class 69 (ii)] [Also in Groups XXX and XXXII] A hydraulic ram wherein an escape valve is adapted to be opened automatically when the ram reaches the end of its outward stroke is arranged so that the excess pressure fluid passes through a passage leading from the front of the piston to an annular space formed behind it, the outlet being at the outer end of the cylinder and controlled by a valve in the piston. A telescopic hydraulic ram for use in tipping bodies of motor vehicles is mounted on trunnions 2, 3 and consists of a central ram 5 and piston 8 in a cylinder 4 having at its lower end a piston 6 movable within an outer cylinder 1 carried by the trunnions. Supply of fluid is by the hollow trunnion 2 and pipe 10 and the exhaust is by way of telescopic tubes 24, 26 with ports 29 leading to the other trunnion 3. The piston 8 of the ram proper carries a ball valve 14 which is disposed beneath a projection 17 on a cross bar 19 and when the piston is at the outward end of its stroke the bar 19 contacts with the end of a sleeve 21 fixed in the cylinder, thereby opening the valve and permitting escape of excess fluid through the passage 22 to an annular space 23 which is under valve control 25 to the inner tube 24. Fluid from 24 passes out at openings in the bottom end into the outer tube 26 and thence away through the ports 29. In order to prevent accumulations of pressure behind the second piston there is also provided a valve 27 controlling a passage 28 leading to the outer tube 26.

摘要： 547,402. Epicyclic toothed gearing. GYRAL GEARS, Ltd., and CALLA, W. M. Jan. 6, 1941, No. 193. [Class 80 (i)] The gearing comprises a casing, an internally toothed ring fixed within the casing, a pair of toothed gyrating gears meshing with the ring and mounted with their centres in diametrically opposed eccentric positions on a common input shaft, wherein the means for transmitting movement to an output shaft includes cranked coupling devices, arranged between the first and second gyrating gears, and a second set of cranked coupling devices between the second gyrating gear and the output shaft. A casing a has fixedly mounted therein a gear ring b with which mesh two gyrating gears h, i mounted on diametrically opposed eccentrics j, k, carried by a driving shaft e mounted in bearings d in a cover c of the casing. The gears i, h are coupled by cranked members each consisting of a disc n and pins o, p set at the same eccentricity as the main eccentrics j, k and mounted in bearings q, r. The inner end e 1 of the shaft e rotates in a bearing s formed in the inner end of the output shaft f -which has a flange t driven from the second gyrating gear h by cranked devices similar to those coupling the two gyrating gears but arranged at right angles thereto.

摘要： 590,129. Winches. GYRAL GEARS, Ltd., and CALLA, W. M. April 13, 1945, No. 9281. [Class 78(v)] In a winch of the kind wherein power is transmitted through a slipping clutch and reduction gearing to a winding drum, pressure is applied to the clutch by two springs, one of which is adjusted initially to give a predetermined adhesion value between the clutch faces and the other of which has hand adjusting means for compressing it and the first spring in order to relax the pressure exerted by the first spring on the clutch members. The driving handle 1 is mounted on a sleeve 2 which is formed integral with a clutch member 4 and is rotatably mounted on a hollow shaft 3. The other member 5 of the clutch forms part of a sleeve 6 which surrounds and is keyed to the shaft 3. A pinion 9 on the shaft 3 engages the gear 10 of a composite pinion 10, 11, 12, the gear 12 of which engages a ring 16 of internal teeth fixed within the casing 30. The gear 11 engages a ring of internal teeth 15 secured to the rope drum 14. The sleeve 3 contains springs 17, 19 which are disposed around bolts 18, 20 and abut at their inner ends against the bolt heads 22, 21. These heads bear against a freely movable cylindrical element 23. The outer end of the spring 17 bears against a plug 24 through which passes freely the bolt 18. A nut 25 on the outer end of the bolt 18 bears against a disc 26a mounted in the sleeve 2, and by adjusting this nut the tension of the spring 17 can be varied. The outer end of the spring 19 bears against a collar 26 which is movable within the shaft 3. The collar is moved inwards by a nut 27 on the bolt 20 which is engaged by a tool inserted through the end of the shaft. By this means the pressure on the clutch elements can be relaxed so that slipping will occur at a load less than that corresponding to the initial setting. This setting is restored by screwing a member 28 inwards along the bolt 20 and continuing to turn it after it abuts against the nut 27. Specifications 519,927 and 537,266 are referred to.

摘要： 585,649. Winches. GYRAL GEARS. Ltd.. and CALLA. W. M. Nov. as. 1944. No. 23710. [Class 78 (v)] A hoisting apparatus comprises a winch enclosed within a casing from which projects a detachable vertical tubular member carrying a pulley at its upper end over which passes the hoisting cable and a pivoted supporting means by which the whole unit may be suspended. Fig. 1 shows a_casing 1 enclosing a winch. A tube 3 is fixed tangentially to the case and-is provided with extensions 4, 5, and 6 the latter supporting a pulley 8 at its end between arms 11. A winch cable 7 with an eyelet 9 is controlled by a handle 16. When the winch is used for hoisting loads into aircraft it is suspended beneath the aircraft by an arm 14 pivoted at 13 to the arms 11 and having a ball connection 15 at its outer end. Fig. 5 shows two such winches hoisting a bomb 20 into a bomb bay of an aircraft. The load in this case swings the winches outward thus balancing the load in the cables 7. In modifications (a) the standard may be deleted and the winch used above the load and (b) the standard may be locked in a horizontal position by a pin engaging the holes 18, 19. Specifications 519,927 and 537,266 are referred to.

摘要： 484,114. Wobbler pumps. CLAYTON DEWANDRE CO., Ltd., and CALLA, W. M. Nov. 2, 1936, No. 29775. [Class 102 (i)] A pump for hydraulic tipping gear comprises a number of plungers 19 in parallel bores operated by a wobbler 22, which is mounted on tapered rollers 23 on an inclined crank 24 on a driving-shaft 25. The wobbler is housed in a chamber formed by a cylindrical extension 3 of the cylinder block. The chamber is closed by a cap 27, which carries one bearing 26 for the driving-shaft. A second bearing for the shaft may be formed in the cylinder block, as shown. The circulating liquid is oil and is supplied from the suction pipe 31 to the chamber 3 by a pipe 32 for lubricating purposes and for the return of leakage past the plungers. The pipe 31 communicates with a passage 20 in a cap 8, which fits on a spigot 4 on the cylinder block. The passage 20 communicates with the cylinder bores through valves 15 housed in screw plugs 14, loops 17 form abutments both for the valve springs and for the plunger return springs 18. The discharge pipe is attached to an opening 8a in the cap 8, which communicates with the cylinder bores through valves 11 and radial passages 6.

摘要： 398,787. Transmitting-mechanism for brakes. CLAYTON DEWANDRE CO., Ltd., EDGE, S. H., and CALLA, W. M., Titanic Works, Lincoln. March 8, 1933, No. 20632. Divided on 397,045. [Class 103 (i).] The transverse shaft to arms on which operating cables for the brakes of a vehicle are connected, is actuated by a sleeve rotatably mounted on the shaft and carrying an adjusting screw bearing against an arm on the shaft. As shown, cables from the four wheel-brakes of a vehicle are connected to arms on the ends of the transverse shaft 3 which can be actuated by either of two sleeves 6, 6 freely mounted on the shaft. The sleeve 6 has a lug 8 carrying a screw 7 which abuts a projection 9 on the shaft and the sleeve 6 has a projection 10b abutting a projection 10a on the sleeve 6. The sleeves may be connected respectively to a hand- and foot-lever or one to a manual and the other to a servo operating-device.. In a modification, the projections 10a, 10b are replaced by an extension of the lug 8 abutting a projection on the sleeve 6 . The screw 7, by which all the brakes may be adjusted simultaneously, may be accessible through the vehicle floor.
