Abstract: 855,331. Magnetic switches. SMITH & SONS (ENGLAND) Ltd., S. March 14, 1957 [March 16, 1956], No. 8344/56. Class 38 (5). A speed-responsive switch has co-operating magnetized and eddy current members, a first of which is fixed to a shaft and the second is rotatable about the shaft axis and held in a datum position by force produced solely between co-operating magnetic parts, and contacts operated by the second member when moved from the datum position at a predetermined speed. In one form, the shaft 4 carries a permanent magnet 7 with radially-spaced magnetic members 9, 11 fixed thereto. The eddy-current member comprises an aluminium cylinder 16 arranged between members 9, 11 and secured to a boss 28 on a spindle 12 coaxial with shaft 4. The boss 28 carries an arm 18 with an armature 19co-operating with polepieces 20 and a magnet 21 so as normally to hold a contact 22 on arm 18 away from a fixed contact 23. When the predetermined speed of shaft 4 is reached, the torque on cylinder 16 overcomes the pull of magnet 21 and the contacts close, and they reopen when the speed falls. The magnet 21 may be a permanent magnet or an electromagnet, the attraction of which may be variable to adjust the predetermined speed. In the latter case, the contacts may be re-opened by momentarily increasing the current through the electromagnet. The Provisional Specification describes another arrangement in which the arm 18 is an armature, the ends of which lie between the arms of two U-shaped polepieces having adjustable stops. In one position, the arm 18 presses two spring contact fingers together, the contacts being re-opened either by manual resetting of arm 18 or by reverse rotation of shaft 4.

Filed: 1926-03-29
Abstract: 249,888. Thunberg, E. J., and Wellton, O. G. March 28, 1925, [Convention date]. Variable-speed ratchet gearing comprises two or more cams 25 upon a driving-shaft 1 which, through sets of articulated reciprocating members 34, 36, or 34, 27, and ratchets 37 drive a shaft 2 continuously. Frames 27 straddle the shaft 1 and carry rollers 26 embracing the driving cams so that as the cams turn the frames reciprocate. In one arrangement, Figs. 1 and 2, the frames 27 are secured end on to rods 34 which reciprocate constantly in fixed guides 35. Each rod 34 is connected by an oscillating lever 42 to a parallel rod 36 carrying a rack engaging a one-way mounted pinion 37. The speed is varied by moving the pivots 41 of the levers 42 transversely in unison, the levers 42 being suitably slotted. The cams 25 are shaped and phased to secure smooth running. Automatic control may be effected by a governor. The construction of ratchet is shown in Figs. 2, 3, and 6. There are inclined bores 16 staggered on both sides of each pinion 37, and in each bore a spring-pressed ball 17. Each pinion 37 is loose between a pair of discs 38, 39 fast on the shaft 2, and in each disc is a ring of ball-engaging recesses 18 spaced to minimize lost motion. It is stated that this ratchet may be adapted for reversing. In an arrangement shown in Fig. 9, there is a single rod 34 in each transmission unit, the speed being varied by varying the obliquity of the separate frames 27 as indicated in Fig. 12. The frames 27 are for this purpose guided in a rocker 30, Fig. 9, tilted by a worm 31. Rollers 32 carried by the frames 27 engage vertical slots 33 in heads on the rods. In the form shown in Fig. 12, the rods are out of line with the shaft 1 so that the speed of the driven shaft may be reduced to zero. The invention is suitable for locomotives with Diesel engines.
