Filed: 1938-09-16
Abstract: 519,190. Skis. TUDSBURY, H. T. Sept. 16, 1938, No. 27046. [Class 132 (i)] Members for securing a boot to a ski automatically become detached if the pressure or movement of the boot becomes abnormal: The toe fastening cotnprises flanged plates 3 having slots 5 sliding on bolts 6 in a plate 8 bolted to the ski. The plates are slid together to grip the toe of the boot but they are slotted to - give resilience so that if there is undue pressure on the toe of the boot the latter can bend the plates apart and free itself. The heel fastening comprises a spring-strap passing round the heel and carried by levers pivoted to the ski towards the toe end. A further strap is secured to the spring strap and also to the rear end of the ski. Thus when the heel is unduly raised the spring strap is pulled from the heel.

Title: Improvements in friction ratchet devices
IPC: F16D41/08
Filed: 1928-09-21
Abstract: 325,558. Merritt, H. E. Sept. 21, 1928. Clutches, ratchet; facilitating changing speed. -In roller-ratchet clutches, particularly for allowing free-wheeling and facilitating gear-changing in motor vehicles, the rollers d, Figs. 1 and 2, are carried in an angularly-movable cage e and the wedge or cam surfaces coacting therewith are formed on separate members c, which are driven by a claw member b, b<1> from the driving-shaft a and are curved on their inner sides to bear directly or through flat springs i on a floating ring h, in order to equalize the load on the rollers, particularly when, as shown, three rollers are provided. As applied to a motor vehicle, a control collar h, slidable on the part b, has fingers k<1> entering recesses e<1> in the cage e to prevent the rollers d from passing into the reverse-drive position. On initial depression of the engine-clutch pedal (not shown) a cam p, Fig. 5, is turned to present a depression p<2> to a roller m<2> on a fork m, which is then slidden to the right by a spring (not shown) to press a friction ring r on the collar k against a surface f<1> on the driven drum f of the roller clutch, in order to synchronize the gear-box tailshaft a and driven shaft g. Further depression of the pedal causes the fingers k<1> to be withdrawn from the recesses e' by the action of a cam surface p<3>, so rendering the clutch bidirectional without shock. A non-return spring catch t coacts with a nose v on the boss of the sliding fork m to hold the collar k withdrawn, so that, for example, the engine can be used for braking, until the catch t is manually released by a Bowden wire &c. In a modification, Fig. 6, the fingers k<1> are omitted, the wedges c being single-acting, and the friction ring r is notched to coact with an overhanging notched flange f<2> on the drum f when fully withdrawn, the parts r, f<2> forming a bidirectional dog clutch. Similar control means are provided. For purposes other than motor-vehicle transmission, single-acting wedges c may be used, the cage e being revoluble against springs to disengage the clutch completely. If the roller-recesses in the cage e be widened, control may be effected by sliding the cage itself on helical splines on the claw member b, b<1>.

A valve 24 for the 2-3 control of a 3-speeds and reverse planetary gear behind a fluid coupling 10 or torque-converter having a bridging friction clutch 14, is arranged so that the bridging clutch is engaged whilst the gear is still in intermediate ratio (second) and is momentarily disengaged during transition between said ratio and the high ratio, to cushion the shift. Gear arrangement. The gear driving shaft 13 is driven by a main input shaft 11, through either the torque converter 10 or its bridging clutch 14, and selectively drives either of two suns 18, 21 through disc clutches 16 or 17 respectively. Long planets 31 on a brakeable carrier 19, mesh the suns 21, 18 directly and through planetary idlers 34 respectively, and also mesh an internally toothed ring 36 on the final output shaft 37 driving a vehicle. Emergency low is by engaging the clutch 16, driving the smaller sun 18, and a brake 20, holding the carrier 19; second speed is by changing from the carrier brake 20 to a brake 22 holding the larger sun 21, the clutch 16 remaining engaged ; direct-drive top is by engaging both selector clutches 16, 17 and releasing the brakes; reverse is by clutch 17 and carrier brake 20. Control valves. A master manual valve (not shown) controls oil-pressure for engaging the clutches and brakes and has neutral, normal drive, emergency low and reverse positions. In " normal drive," the manual valve supplies pressure at 25 to a 2-3 valve 24, Fig. 2, operated automatically in response to vehicle speed. In the initial position this pressure 25 is fed to ports 26, 27 supplying the clutch 16 and brake 22 for second speed, fluid-drive. Speed increase shifts the valve right, cutting off an exhaust port 29 from, and pressurizing a line 28 feeding the converter bridging clutch 14 for second-speed, mechanical drive, at a time when the torque-converter ratio approaches 1 to 1. Further speed increase shifts the valve 24 further right to supply lines 26, 30 and 28 of all three clutches 16, 17 and 14 for direct mechanical drive. In reaching this position, the valve 24 passes through an intermediate position in which, before pressurizing the clutch line .30, it momentarily exhausts at 29 the feed line 28 of the torque-converter bridging clutch 14.

Class 75(i) [Also in Group XII] In a combustion apparatus in which combustion is supported in a ducted flow of combustion supporting gas of flame extinguishing velocity, there being a stabilized pilot flame in the said flow, the fuel and gas being mixed in a diffusion zone upstream of the said pilot flame, flash back is avoided by distributing the fuel to give a non-uniform fuel/gas ratio over the cross-section of the flow. Further fuel may be introduced preferably downstream of the pilot flame zone, the distribution being complementary to the first mentioned fuel so as to make the overall fuel/gas ratio more uniform. Thus the distribution of the first-mentioned fuel, pulverulent or liquid, may be circumferential, while the second supply may be radially distributed. Specification 684,669 is referred to.

Abstract: 916,478. Twisting wires together. UNITED STATES STEEL CORPORATION. Aug. 5, 1960 [Aug. 11, 1959], No. 27292/60. Class 83 (4). [Also in Group I] In a wire-tying machine in which a wire W, Fig. 4, placed about a package or bundle P is tightened by a tension head 114 for engaging one end of the wire whilst the other end thereof is held against movement in the gripper 112 and overlapping portions of the tensioned wire are twisted by a pinion 106, the tension head 114 is operable by a shaft 6, Fig. 5, through means effective on rotation of the shaft in one direction only. The twister pinion 106 is rotatable by means including a single-revolution clutch effective on rotation of the shaft 6 in the other direction only. The machine includes a reversible motor 30 which may be electrically, hydraulically or pneumatically powered, coupled to the shaft 6 and means are provided for retaining the tensioning head in tensioning position during rotation of the shaft in the other direction. Tensioning.-The motor 30 is operated to rotate the shaft 6, Figs. 5, 9, via gears 34, 38 and idler 36 which causes like rotation of a hub 52 which is keyed to the shaft 6 by key 26 mounted on one end of a slide thrust rod 22 biased to the left of Fig. 5 by a spring 16. The projecting ends of the key 26 rotate a collar 46, the rotation of which is transmitted to a sleeve 40 through connecting pins 44 which are engaged by the straight sides of depressions 48, Fig. 6, in one side of the collar 46. Rotation of the gear 42 fast on collar 40 causes rotation of the drum 114. When the wire around the package achieves a predetermined tension, the amount of force necessary to rotate the drum 114 becomes greater than the force exerted by spring 16 on the rod 22, the force being variable by means of screw cap 14. The ends of the key 26 will then ride out along the inclined sides of depressions in the collar 46 so that the sleeve 40 is no longer rotated. A pawl is engaged with the ratchet 120 to hold the drum 114 stationary. Twisting.-Motor 30 is reversed to rotate the shaft 6 and hub 52 in the opposite direction. A spring-loaded pin 68 which previously engaged the inclined side of a pocket 74 in the side of the gear 72 engages the straight side to effect rotation thereof. Twister pinion 106 is rotated by means of intermediate gear 76. After one revolution of the hub 52 the arm 58 of the pawl 57 engages the slot 70 of the pin 68 so as to move the pin out of the pocket 74 in the gear 72 to cause the latter to stop rotating. Cutting.-As the twisting is completed, rotation of gear 34 causes a pin 104 to approach a rocker arm 88 keyed to a shaft 78 and tilt it downwards which causes shaft 78 to be rocked, cams 100, Fig. 19, on the ends of the shaft 78 engage spring-loaded cutter holders 102 to pivot them downwards to cut the wire W against the lower arms of the yokes 110 at each end of the knot.
