Title: Joint assemblies
IPC: B66C3/18
Filed: 1973-08-24
Abstract: 1448841 Pipe couplings; valves CATERPILLAR TRACTOR CO 24 Aug 1973 [25 Aug 1972] 40238/73 Headings F2G and F2V [Also in Divisions E1 and B8] In a clamshell bucket assembly (Fig. 2) of a hydraulic excavating machine, a joint assembly 24 includes a tubular member 50 (Fig. 7) having a longitudinal bore 52, a lateral passage 60 through the body of the member 50, a longitudinal shaft 40 disposed within the bore 52 with part of its outer surface in slidable contact with the inner surface of the member 50, the shaft 40 being rotatable about its longitudinal axis within the member 50, a passage 66 in the shaft body, and an annular passage 68 defined between the inner surface of the member 50 and the outer surface of the shaft 40 and providing continuous communication between the passage 60 and the passage 66 irrespective of the position of rotation of the shaft 40 relative to the member 50. The member 50 is disposed in a frame 38 which allows the member 50 a degree of longitudinal movement although rotary movement is limited by a pair of external longitudinal ears on the member 50 engaging an internal rib defined by the frame 38. The entire weight of the shaft 40 is supported by the frame 38 at an annular shoulder 48. A second lateral passage 62 in the member 50 communicates with a second passage 64 in the shaft 40 by means of an annular passage 70. The passages 64, 66 convey fluid to a hydraulic cylinder 26 to operate the jaws 86, 88 of a bucket 28. Valve means 164 (Figs. 7, 8) are fixed to the head end of the cylinder 26 and contain a valve spool 168 which is biased in the position shown (Fig. 8) by means of a spring 180. In this position fluid pressure in passage 64 is transferred to a pipe 172 and thence to the rod end of cylinder 26, thus raising piston rod 114 and closing the jaws 86, 88. To open the jaws, fluid pressure is applied to passage 66 and thence to the head end of the cylinder 26. This pressure is sufficient to shift the valve spool 168 to the right (in Fig. 8) by means of passage 182 and chamber 181, to allow fluid expelled from the rod end of cylinder 26 to flow into passages 172, 176, 178 and thence the head end of cylinder 26. Thus the pressure in the latter is increased to speed opening of the bucket. Extended portions of the jaws 86, 88 comprise stop members 200, 202 having end portions with flat surfaces 204, 206, these surfaces contacting each other across the full flat surface of each to limit opening movement of the jaws. Powered rotation of the bucket assembly may be effected by means of a hydraulic motor 222 (Fig. 7) which drives a chain 224 and thence a sprocket 46 secured to shaft 40. Fluid pressure is applied to passages 60, 62 in the tubular member 50 by means of hoses 132, 130 coupled as described in Specification 1,448,842. The bucket assembly is fitted with a cushioned stop 210 to limit pivoting as described in Specification 1,448,843.

A self-centring castor includes a cam 9 (Figs. 1, 4), or 9a (Fig. 8), and an associated spring 10 or spring urged member 15, either one of the cam 9, 9a or the spring 10 or spring urged member 15 being associated with the fixed part of the castor and the other with the wheel fork 4, and the cam being profiled such that the action of the spring 10 or spring urged member 15 on the cam face always tends to move the wheel fork to a fore and aft aligned position. In one embodiment (Figs. 1, 4) on attachment plate 1 carries a fixed stem 3 extending through the combined bearing plate and wheel fork 4, the semi-elliptical extension on cam 9 on the stem 3 being engaged between block springs 10 anchored at one end 11 to the wheel fork 4 and having free ends engaged in a hole 12 in the opposite side of the fork. Outward bowing of the blade springs 10 on rotation of the fork 4 produces a centring action. In an alternative cam arrangement (Fig. 5) a circular-section extension 9 on the stem 3 carries a plate member 13 having protruding ends 14 which hold the springs 10 when the fork is off centre. In another embodiment (Fig. 8), the castor stem carries a heart-shaped cam 9a which is engaged by a roller 15 carried on a lever 16 pivoted at one end 17 to the wheel fork 4, the roller 15 being urged into contact with the cam 9a by a spring 19 connected to the free end 18 of the lever 16 and anchored, as at 20, to the wheel fork 4.

Abstract: 1,141,056. Topping-up device. A. M. KENNEDY. 11 Sept., 1967 [15 Sept., 1966], No. 41194/66. Heading H1B. A topping-up device for an accumulator according to the invention comprises a water reservoir (11), a pipe (12) connecting the reservoir to the accumulator case (10) and making a fluid-tight joint therewith, the pipe projecting into the case and terminating below the normal acid level, a manually operated valve (14) in the pipe opening of which permits water to pass into the case until the acid level rises above the end of the pipe and the pressure of gas trapped in the case balances the head of water in the reservoir and pipe whereupon the valve can be closed, and a vent pipe 15 which makes a fluid-tight connection with the case and terminates below the normal acid level therein while its upper end is such that when the battery is topped up acid is forced up the vent to form a column which balances the pressure of gas in the casing, such column sealing the vent pipe whilst permitting gas generated in the case to escape when the foot of the vent pipe is uncovered. In another embodiment (Figs. 1 and 2, not shown) the bottom end of the vent pipe and filling pipe constitute a single pipe linked by a 2-way valve to the reservoir in one position and the vent in the other. In either of these embodiments the valve may be spring biased to its closed position with respect to the reservoir. The topping-up device may be modified to serve more than one cell (Figs. 5 and 6, not shown). The level of liquid in the reservoir may be below that in the accumulator if the necessary pressure head is provided by a pump or a heavy or spring-loaded piston (Figs. 7 and 8, not shown).

Abstract: 1,083,306. Automatic voltage control. ROBERT BOSCH G. m. b. H. Oct. 16, 1964 [Oct. 17, 1963], No. 42228/64. Heading G3R. [Also in Division H2] The output voltage of a three phase constant field interdigitated pole generator (see Division H2), whose windings 21, 22, 23 supply charging current to a battery 28, is automatically regulated by semi-conductor controlled rectifiers 24, 25, 26 which, with uncontrolled rectifiers 30, 31, 32, rectify the generator output voltage. With the battery voltage below a predetermined level a transistor 41, biased from potentiometer 45 through a Zener diode 43, is blocked, thus allowing self-excited oscillations generated by a unijunction transistor 42 and a capacitor 53 to fire the rectifiers 24, 25, 26 at the beginning of each positive half cycle, the signals being transmitted through transformer windings 58, 60 and decoupling resistors 64, 65, 66. These oscillations collapse and rectifiers 24, 25, 26 are thus blocked when the battery voltage rises above the predetermined level to make transistor 41 conductive. In a modification Fig. 4 (not shown) the rectifiers 24-26, 30-32 are interchanged, the transformer is omitted and unijunction electrode 57 is connected directly to the rectifier control electrodes, which are situated near the terminal zone of the anode leads.
