Abstract: 431,588. Motor-vehicle steering-gear. BAILEY, R. W. H., 36, Ashbourne Road, Derby. Feb. 14, 1934, No. 4940. [Class 79 (v)] The drop arm or pendulum lever b of the steering-gear a' is not directly connected to the steering arm c<1> on the stub axle a<3>, but carries a balance lever pivoted at b', one arm b<2> of the balance lever being connected by a link c to the steering arm c<1> and the other arm b<3> being connected to the stub axle through a reversing lever d<1> in such manner that movement of the stub axle, caused by road shocks, relatively to the drop arm causes the balance lever to be displaced to compensate for such movement. In the construction shown in Figs. 1 and 2, the arm b<2> is connected by a link d to the arm d<1> of the reversing lever which is pivoted at d<3> to the chassis frame a, the arm d<2> of the lever being connected by a link d<4> to a ball joint d<5> concentric with the steering pivot of the stub axle a<3>. When the stub axle moves vertically relatively to the frame the link c moves the lower arm of the balance lever in one direction but the link d<4>, acting through the reversing lever and link d, moves the upper arm in the opposite direction so that the lever pivot b<1> and the drop arm are not affected. The invention may be applied either to vehicles having a through front axle or to vehicles with independently-sprung wheels. In a modification the reversing lever instead of being pivoted on the chassis frame, is pivoted on the end of a swing- ing link pivoted on the frame, a lever coaxial with the steering pivot being connected by links with the lower ends of the drop arm and the reversing lever respectively, and the drop arm being further connected by a link to the swinging link.

Abstract: 100,274. British United Shoe Machinery Co., (Assignees of Meyer, W. C.). April 9, 1915, [Convention date] Sole-levelling. -Relates to sole-levelling machines, such as those of the type described in Specifioations 10883/95 and 8880/08, in which a jacked shoe and a roll or other levelling- device are moved relatively to cause the device to operate on all parts of the sole, and consists in the provision of automatic mechanism whereby the direction in which the device is moved to rub the sole is reversed at one or more predetermined times during the traverse of the device along the sole. The invention is described particularly with respect to a twin sole-levelling machine of the vibrating-roll type, in which the jack-oscillating mechanism is of the kind described in Specification 8880/08, while the mechanism for tripping the rolls is of the type described in Specification 10678/09. Each roll 16, Figs. 4 and 5. is freely rotatable upon a shaft 32 mounted in a vibrating yoke 30 at one end of a rod actuated by an eccentric, and in connexion with each roll, there is provided a double-acting one-direction clutch which can be set to lock the roll so that it rubs in either direction, and when so locked, to permit the roll to have a rolling action in the opposite direction; or the clutch may be set in a neutral position. The clutch mechanism comprises a fixed member 56 keyed to the shaft 32 and provided on its periphery with a series of flats 58, opposite which are placed rollers 60 carried by a member 62 mounted to be rotated freely about the member 56; between the rollers 58 and the roll 16, and secured to the latter, is a friction ring 64. The member 62 is furnished with a stud 66 connected by a spring 68 with a bell-crank 70, which is adapted to be oscillated by a rod 74 having a roll 110 movable in a segmental groove 108 on a head 106 of a locking-slide 78. This slide is mounted in guides 80 en the side of the rollcarrying bed, and is connected by an arm 82 to a rock-shaft 84, which is adapted to be oscillated through links 88, 90 from a roll-locking cam on the main cam shaft. In operation, the jack is traversed under the roll 16 so that it commences its. rolling action on the sole at the point A, Fig. 7, traversing the sole in the direction of the large arrows. When it reaches the ball line 7-7 and begins to tilt, the clutch mechanism is operated to lock the roll, so that it rubs towards the heel, and this continues until the centre line 9-9 of the shank is reached, whereupon the locking-mechanism is changed over, and the rubbing action from the line 9-9 to the breast line 8-8 is reversed. The direction of rubbing is indicated by small arrows. When the roll reaches the point 7 on the outside edge of the shank, the clutch is set in neutral position until the curvature of the sole changes, such as at C, when the roll is again locked. The action of the roll when it traverses the inside portion of the sole is also indicated by the large and small arrows. Specifications 13230/13, 17556/14, and 104,714 also are referred to.
