There is a double row of balls.
scribes a. double-row ball bearing in which the inner race ring is curved, and the whole bearing is so assembled that balls can be easily withdrawn and replaced. The distance ring is corrugated, as shown in the drawing, and it is provided with grooves to receive the balls. The ring is so designed as to cause only the neutral inner poles of the halls to bear against it. .
Two or more of the spherical grooves are extended in a straight line to the inside of the ring to permit the insertion of the balls.
31. FISCIIER, No. 5803, dated 8th March, 1913.----This specification describes a simple method of mounting road -wheels on a live axle. The axle is contained in the usual form of casing, and it is provided at its cuter end with a flange and a sleeve which projects inwards from the flange towards the centre of the axle. Within the recess formed by the sleeve, ball bearings are mounted.
1 he outer end of the axle is made a slightly larger diameter, and tho brake-drum is pushed on from this end up against the aforementioned flange. The wheel is next placed on the axle from the same end, and a cap-nut is screwed on which Jocks all the parts in position. The hub is held together by means of bolts, and the nuts are arranged on the inner side of the wheel.
Suitable holes are provided in the brake drum and in the flange on the axle for these nuts to enter, so that driving connection is established between the axle, brake drum and wheel hub.
The wheel can be dismounted by unscrewing the cap-nut and sliding off the various parts.
The machine is steered from the rear.
an a single pair of driving wheels, and coupling this to tha frame, which carries the shares, by a pivot joint.
A stout beam carrying the plough shares is pivoted to a cross beam on the motor framework, and this may be tilted slightly in either direction. The machine illustrated is steered by a man walking behind it. The equipment may be set, if desired, to plough in a circle, or, if it be adapted to run with one wheel. in a furrow, it may be set to " hug" that furrow, in which case it is automatic in action and only needs attention at each headland,
C. CHALLINErt, No. 14,044, dated 90'. November, 1912.— The wheel described in this specification has spokes of either '1' or U section, and the rim of the wheel has bridge-shaped recesses. These recesses are arched inwards towards the centrs of the wheel and, in the case of the T-section spokes, are mach quite narrow. The base of the arch is also recessed below the outer surface of the wheel, as shown in the accompanying illustrations.
A spoke is secured on each side of the wheel, and is bout over where it meets the rim, so that the T section lies within, and fills up, the gap formed by the bridge-pieces. The crossflange of the T lies flush with the rest of the rim and forms part of the tread The spoke is welded in this position or may be riveted if desired.
The inner ends of the spokes are suitably shaped and butt together around the hub and it its side flanges, so that the faces of the spokes and side flanges lie flesh with each other. All the spokes may be welded together at the hub and also riveted to the side flanges. It is claimed that this form of wheel is well suited to resisting unequal strains set up by uneven road surfaces
