Abstract
1,268,111. Linkwork; toothed gearing. MICROMEDIC SYSTEMS Inc. 1 April, 1969 [2 April, 1968; 19 Aug., 1968], No. 17068/69. Headings F2K and F2Q. [Also in Division F1] A pump 1a has a reciprocating piston 102 driven by a motor 4 through intermittent toothed-gearing, a variable-throw crank-mechanism 320 and a lever 339 pivoted at 340. The mechanism 320 has rotary members 332, 328 with slots 323, 329 housing an axially-movable spring-loaded blade 324 attached to a micrometer screw 601 and engaging with elements 334, 335 on an eccentric ball-bearing 333, which is coupled to the lever 339 by a rod 336 and ball 337: Rotation of the screw shifts the blade axially to change the eccentricity of the bearing. A counter 701 is coupled to the screw by a chain 703. The toothed gearing includes a pinion 14 having a frictional torque-limiting device, Fig. 8 (not shown), and meshing with a gear-wheel 301 having recesses 307, 307<SP>1</SP> aligned with a gear-wheel 306 coupled to the mechanism 320, the pinion being driven by the motor through speed-reducing gear 5. The recesses result in intermittent rotation of the wheel 306, arms 310 and pins 311, 311<SP>1</SP> being provided to turn said wheel into mesh with portions 308 between the recesses. The pinion also drives a second pump through gear-wheels that are identical to the gear-wheels 301, 306. In a second embodiment, Figs. 12 and 15, the variable-throw crank-mechanism includes a yoke 370 connected to a " slide " 368 in a pair of slideways 369 within a fixed sleeve 364, the slide engaging slidingly with a crank-pin 357 coupled pivotally to an axially-movable head 363 and a pin 359 in blocks that can slide axially in grooves 360 within a rotary member 356, which is driven by the motor through gearing similar to that shown in Figs. 1 and 2. Rotation of the member 356 makes the pin 357 revolve along an asymmetric conical-path (the pin being horizontal as shown only when at its uppermost position); and thus by shifting the head 363 axially by means of a micrometer screw 378 the stroke of the piston 135 is varied without affecting the top-dead-centre position. Arms 353, 355 effect intermittent rotation of a valve member 231.
