Abstract: 192,407. Soc. des Etablissements Malicet et Blin. Jan. 30, 1922, [Convention date]. Brakes, arrangement and disposition of, and braking. -All four wheels of motor and other vehicles are simultaneously braked by means of a floating and rocking equalizing shaft, and the steering-wheel brakes .are each applied by a member which is so situated with regard to the steering- pivot that either (1) the steering-wheel brakes are not effected by the swivelling of the steering-wheels, or (2) a greater braking- effect is exerted on the wheel on the inside of the curve. The equalizing- shaft 19, Fig. 5, is suspended from the frame by swinging links 20 and is connected to the four brakes by arms 21 and links 25, 26. A pedal 27 actuates the shaft 19 through a bell-crank lever 29, a link 30 and an arm 31 on the shaft., this arm being normally horizontal so that the link 30 does not tend to move the shaft horizontally. The steering-wheel brake segments have inclined ends 18, Fig. 4, acted upon by rollers 17 carried by a bar 5 sliding in a part 8, Fig. 2, of the swivelling wheel-axle. The bar 5 is formed with a rack actuated by a pinion 2 carried by a fixed support 1 and rotated by an arm 3 controlled by a spring 4. The path of the contact point of the bar 5 with the brake-segments is not appreciably different from an involute of the pitch circle of the pinion 2, and if, when the steering-wheels are set for straight running, the point of contact of the axis of the bar with the pitch circle is on the axis A-A of the steering-pivot, the steering-wheel brakes are not effected by the steering-movement of the wheels. However, by arranging the lastmentioned point of contact off the line of the steering-axis the braking effect on the wheel which is travelling on the inner side of the curve may be made greater than that on the other wheel. Deflectable axle-ends. - The steering-wheel rotates on a spindle secured to a member 8 carried by the steering pivot.

[Class 83 (iii)] A gear-shaping machine having a reciprocating ram 2 carrying a toolholder pivoted at 4 has means for reversing the pivotal relieving movement of the tool - holder so that the machine may cut either an internal gear 30 or an external gear 30<1>. The ram carries a bracket 3 having bearings for the shaft 4 on which is pivoted the carrier 10 of a tool spindle 6 carrying a pinion cutter 7. The cutter is adapted to generate teeth in the blank 30, the blank and cutter having the usual intermittent generating movements and the ram being moved down for the cutting stroke in the intervals between the generating movements. The tool-spindle is vertical during cutting but is swung away from the blank on the return strokes by movement of the carrier 10 about the pivot 4. The frame carries a fixed rack 11 engaging a pinion 12 on a shaft 13 journalled in the bracket 3. A ring 34 splined on this shaft is frictionally connected to a member 14 having an arm 42 forming part of a toggle connection with a member 16. This member is connected by screws 18, with a shaft 17 mounted in lugs of the bracket 3 and having an eccentric portion 40 passing through a block 19 which is guided in a part 39 of the tool carrier. In operation, when the ram moves downwards the friction gearing 34, 14, straightens the toggle links and rotates the eccentric so that the tool holder is held vertical against a spacer 20. On the upward stroke the toggle is broken and member 16 actuated to move the eccentric so that the tool-holder abuts a thinner opposed spacer 21 which holds it in the tool-relieving position. To adapt the machine for cutting a spur gear 30<1> the screws 18 are withdrawn, the eccentric 40 rotated 180‹ and refixed and the spacers 20, 21 interchanged from the position shown in Fig. 1. In this case, when the ram moves down the toolholder is held vertical for the operative stroke, and when the ram returns the tool-holder is relieved by a movement to the left where it is held against the thinner spacer. The machine may be adapted to cut on the upward stroke, the direction of rotation of the gear 12 being reversed by an intermediate gear between it and the rack 11.
