IPC: B64D39/00
Filed: 1917-02-21
Abstract: 126,707. Dickinson, W. J., and Stark, A. H. Feb. 21, 1917. Anemometers and air-current indicators.-Relates to turbines actuated by air currents and applicable as anemometers or auxiliary powergenerating devices on aircraft or other moving bodies, or as wind motors; the turbine may drive a dynamo or air compressor which is cooled by the exhaust air. The turbine d driving the dynamo g is mounted in a casing k of streamline formation having a mouthpiece a of vena contracta form and exhaust slots l which may be fitted with baffles, cones, or other current-inducing devices utilizing the entraining action of the current of air flowing outside the casing k. A second vena contracta m may surround the slots l and may itself be enclosed by a casing m<1> of stream-line formation. The apparatus is regulated by automatic throttling, preferably at the rear of the turbine. Thus the slots ! l may be controlled by a revoluble ring valve v actuated through suitable linkage by a centrifugal governor or by a solenoid q connected, for example, across the dynamo terminals. Alternatively the exhaust passage n may be controlled by a series of shutters o connected to a common operating ring p linked to the core of the solenoid q. Another throttling device for use either on the exhaust or inlet side of the turbine comprises an iris diaphragm arrangement of leaves or valves w, Fig. 3, which are pivoted on the turbine rotor so that when the speed becomes excessive they are thrown outwards by centrifugal force against the action of a spring band x bearing on studs y on the leaves w.

Title: An overload device for power-driven agricultural tractors
IPC: A01B61/00
Filed: 1949-01-31
Abstract: 679,118. Controlling motor-vehicles. CUMMING, A. June 7, 1950 [Jan. 31, 1949], No. 2618/49. Class 79(v) [Also in Group X XXII] A draw bar overload unit for a tractor comprises a frame horizonally mounted on the tractor, slidably engaging an anchoring element on the tractor and carrying an agricultural implement, the frame including side frame members supported on the tractor at positions spaced from the anchoring element, which element and the frame have interengaging locating means locking the frame relatively to the tractor, which means disengage on the implement encountering an adamant obstruction so that the frame is slid rearwardly relatively to the tractor, the frame and element having associated buffer springs which become loaded as the frame is slid rearwardly and the frame is coupled to a drive control member of the tractor so that rearward sliding of the frame cuts off the drive to the wheels of the tractor. As shown the frame comprises the side members 1 interconnected by a crossbar 4 and carrying side brackets 5 for the coupling of the implement. The members 1 are guided for longitudinal movement by guides on a rear bracket 3 secured to the tractor, and at their forward ends carry studs 13 engaging slots 6 'in ears 7 carried by a front bracket 2 secured to the tractor. Secured to the bracket 2 is a lug 14a carrying a casing 14 for the locating means. From the rear end of the casing 14 projects a plunger bar 21 connected to the crossbar 4. Within the casing the bar 21 has arcuate notches 23 engaged by rollers 24 carried by spring- loaded shoes 25, lateral movement of the bar 21 being prevented by a backing bar 28. Excessive implement resistance causes the shoes 25 to be moved laterally to release the rollers 24 from the notches 25, thus permitting sliding movement of the frame, which movement compresses the buffer springs housed in casings 8 secured to the ears 7. Secured to one member 1 is a lug 11 to which is connected a link 33 of adjustable length carrying an L-shaped slot 34 which is engaged by a stud 35 on a lever 36 forming part of the operating linkage between a pedal and the tractor clutch. With the stud 35 in the arm of the slot 34 shown in Fig. 8, movement of the link 33 due to the sliding of the frame will cause the tractor clutch to be disengaged. Pivotally mounted on the stud 35 is a locking piece 37 carrying a pin 38 engaging an L-slot 39 in a bracket 40 bolted to the clutch housing 41. To the bracket 40 is pivoted an arm 46 controlled through a rod 45 by a pivoted hand lever 42, a finger 46a on the arm 46 selecting which arm of the slot 34 the stud 35 enters. When the clutch has been disengaged by movement of the link 35 the pin 38 of the locking piece 37 drops into the arm 39b of the slot 39 and thus prevents pedal re-engagement of the clutch until the lever 42 has been lifted.
