Title: Drive means for agricultural implements
IPC: A01D34/27
Filed: 1976-04-06
Abstract: The machine working, for example, as a mowing machine has a working member (4) which is lowered in the working position (Figure 1) and which is pivoted upwards in the rest or transport position. The drive of the member (4) takes place via a drive shaft (8), belt pulleys (11, 12) and driving belts (29). The drive shaft (8) has an output journal (8'). This can be used for driving a further appliance (9, 10). The latter can be carried out even when the working member (4) is in its non-driven rest or transport position, since the belt drive (11, 12, 29) is ineffective in this position. The belt (29) is brought out of non-positive engagement with the driving belt pulley (11) by reducing the centre distance between the belt pulleys (11, 12). <IMAGE>

Title: Improvements in and relating to clutches
IPC: F16D43/18
Filed: 1930-05-09
Abstract: 346,198. Friction clutches ; motor driving-arrangements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.- (Assignees of Norris, M. L. ; 522, Madison Street, Fort Wayne, Indiana, U.S.A.) May 9, 1930, No. 14382. Convention date, May 10, 1929. [Class 80 (ii).] In friction clutches in which a centrifugallyactuated member transmits torque directly from the driving to the driven member and frictional driving-means for the centrifugal member acts solely for accelerating it, in order to allow the driving-member to attain substantially full speed before sudden application of the load, the driving and driven members have concentric peripheral flanges, the friction elements, which are acted on by the loosely-driven centrifugal device, being lodged in openings in the inner flange. The rotor 13 of an electromotor is secured to a sleeve 15 loose on the shaft 14 and to a clutch driving-member 16, carrying loosely in slots 19 in its peripheral flange 18 cork-composition or other friction elements 20 coacting with the surrounding flange 24 of a driven member 21, 22 keyed to the shaft. Centrifugal weights 25, adapted to cause the elements 20 to grip the drum flange 24, are held from expansion, until a predetermined speed is attained, by an annular spring 26 lodged in notches 27 opening alternately to opposite sides of the weights, which are radially guided by the arms 30 of spiders 29 engaging recesses 28 in their faces. The spiders bear with light friction on the sleeve 15, but are held from contact with the parts 16, 21 by washers 33, so that the weights attain the critical speed somewhat later than the parts 13, 15, 16. Engagement of the clutch is thus sudden, the kinetic energy of the driving parts being utilized to start the load. In a modification, the driven member is a pulley or other transmission element, provided with an extension forming the annular clutch surface and loose on the driving-sleeve, which may be driven by any means and is integral with the driving-member of the clutch.

IPC: G01P7/00
Filed: 1918-09-09
Abstract: 131,184. Morris, D. K., and Porter, A. W. Sept. 9, 1918. Speed indicators acluated by accelcrometers.- Consists in the utilization, for integrating accelerations, of the movements of a fluid which, by its viscosity or by artificial restriction, is strongly damped, indicating and measuring means being provided. The restriction, or the viscosity, must be very great so that the amount of liquid moved is very small in comparison with the volumes acted upon. In the form shown in Fig. 1, the apparatus comprises a pair of vessels a, b, partly filled with liquid and connected by capillary tubes c, d, the lower tube containing a bubble index e and the upper tube a liquid index f. Acceleration (horizontally) of the apparatus will cause the index c to move proportionally to the acceleration, so that its total displacement represents the accrued speed, while, since the difference of air pressure in the vessels is proportional to the movement of the index e, i.e. to the speed, the total movement of the index f will represent the distance traversed. For indicating vertical accelerations, the effect of gravity is eliminated by the employment of a. vertical column of liquid which compresses the air in the lower receiver. The second tube in this case passes between the upper receiver and a third air-filled receiver. In modifications (a) the receivers are formed by airtight partitions in a vertical cylinder, the index tube being bent to a circular form surrounding the chamber; (b) a ring a, Fig. 5, floats on the surface of a highly viscous liquid, and is attached by springs g to a pointer f carrying a damping disk d operating in a nearly closed vessel e full of viscous liquid.

Title: An improved machine for assembling and filling machine-gun cartridge belts of the disintegrating link type
IPC: F42B39/10
Filed: 1935-05-20
Abstract: 457,200. Assembling and charging cartridge belts. WHITING, A. J., Air Armament School, Royal Air Force, Eastchurch, Sheerness, Kent. May 20, 1935, No. 14655. [Class 92 (ii)] A machine for assembling and filling machinegun cartridge belts of the disintegrating-link type, comprises a shoot 2 down which the links descend by gravity, the links being correctly orientated in the shoot by a guide 3. The links pass over a flat spring 2a in the shoot to belt guides 4, 5 having recesses 5a to accommodate the eyed portions of the links, the recesses being spaced longitudinally a distance equal to the pitch of the links. A carrier 6 which is reciprocated vertically by cams 7, 8 and horizontally by a crank-pin 9 engaging a vertical slot 11 in the carrier, has recesses 6a in its upper surface and, at each actuation, operates to lift a juxtaposed pair of links and advance them from the first recess 5a to the second recess, the front eyed portion of a fresh link then falling down the shoot into alignment with the rear eyed portion of the previously assembled link. A block 15 pressed downwardly by springs 16 has recesses in its under face corresponding to the eyed portion of the belt-links and is raised periodically by cam mechanism 22, 23a to permit longitudinal feed of the links, but is not raised sufficiently to allow misalignment of the links to occur. Cartridges are fed by hand into a hopper 24 and pass by a direction determining passage 43 on to a cartridge support 26 which is pivoted at 30 and tilted upwardly by a spring. Jamming of the cartridge in the neck of the hopper is prevented by a leaf 43 which is carried on a spindle 44 and rotated inwardly and upwardly by a cam 45 governed by an extension 46 of a ram 29, to release the cartridges one at a time. The positioned cartridge is pushed forward into aligned eyed portions of adjacent links, to constitute the link coupling, by the ram 29 reciprocated by a crank-pin and slot mechanism 33, 36. Recesses are provided in the belt guides to accommodate the bullet x and cartridge rim. The various mechanisms are intergeared to operate in timed relation and are driven by power, treadle, or hand.
