Title: Rotary positive displacement pump
IPC: B62D5/06
Filed: 1971-04-19
Abstract: 1328728 Rotary positive-displacement pumps FORD MOTOR CO Ltd 19 April 1971 [2 April 1970] 25720/71 Heading F1F An hydraulic pump has a rotor 36 with spring- loaded slippers 40 that engage with a cam ring 22, which has a pivot extension 28 and carrier pins 34, 55 abutting a fixed housing 10 to form pressure chambers. High and low pressure ports 48, 44 are disposed in the housing as shown, the port 48 being connected to a hydro-kinetic torqueconverter (not shown). During normal operation pressure is applied to the exterior of the cam ring through a passage 80 from the port 44 and through a passage 64 and a further passage 66 controlled by a valve element 70, the forces thus acting on the ring being balanced. When the output pressure falls an externally-applied force moves the element 70 in opposition to the pressure acting thereon to partially shut off the passage 66 and thus unbalance said forces. The corresponding displacement of the cam ring increases the rate of flow and thereby causes the element 70 to re-open the passage 66. Modified forms of the pump, Figs. 3 and 4 (not shown), differ chiefly in regard to the pivot for the cam ring and the valve element and related parts.

Filed: 1927-10-07
Abstract: 303,220. Linotype & Machinery, Ltd., Banks, J. N., and Spence, F. Oct. 7, 1927. Delivery apparatus; cutting-apparatus ; grappers and gripper mechanism.-In sheet-delivery mechanism for printing-machines in which a delivery carriage conveys the sheet over the pile during its outward travel and allows the sheet to drop on to the pile during its inward movement, a gripper is provided to take the sheets from the carriage and moves outwards, laterally and downwards so as to deposit the sheet on the pile against front and side lays. As shown, Fig. 1, two grippers or sets of grippers moving laterally in opposite directions are adapted to take the two halves of centrally-slit sheets from tapes 31 which unwind from beneath the sheets to allow them to drop on the piles 32, 33. Each gripper 1, 2 is reciprocated in a bracket 4 extending at an angle to and adjustably carried by a transverse shaft 6 oscillated from the main shaft of the machine by means of a crank 10 and link 11. The upper jaw 1 of each gripper is pivoted at 20 to a slide 21 carrying the lower jaw 2, and a spring 24 tends to hold the jaws in contact. As the slide 21 is moved outwardly an adjustable cam 26 on the bracket 4 engages a roller 25 on the jaw 1 so as to release the sheets at any required time. The roller 25 at the same time moves under and tilts a ramp 27 pivoted on the bracket 4 and normally held depressed by a spring 28 attached to an arm 29 thereon. On the inward movement of the slide 21, the roller 25 first rides up the ramp 27 so as to open the gripper to take a shot from the tapes 31 and then passes over the end of the ramp so as to cause the jaws 1, 2 to grip the sheet under the action of the spring 24. The mechanism for reciprocating the slide 21 in the brackets 4 consists of a bar 13 reciprocated axially in lugs 12 on the brackets 4 through a link 19 pivoted bell-crank 18 engaging a grooved member 17 feathered to the shaft 6. Rack members 14 on the bar 13 mesh with toothed sectors 15 serving to oscillate arms 16 slotted to engage pins 22 on the slides 21.
