Abstract: 3640. Schultz, E. Aug. 31, 1912, [Convention date]. Equalizing load on wheels and Springs; guiding vertical play; springs, arrangement of.-In a spring suspension wherein the axles are connected to rocker arms which are connected together on each side of the vehicle through normalizing - springs, one or more radius-links are employed to prevent backward or forward tilting of the steering-axle. Fig. 7 shows the front axle connected to the spring arm u of a rocker u, s, the arm s of which is connected to a similar device at the rear axle, normalizing - springs being interposed. The spring u is pivoted to a shackle x which is pivoted about a longitudinal pin x<2> to a sleeve y capable of rotating about the axle. Two radius links h, i pivoted at their rear ends to a bracket on the chassis are pivoted at their forward ends to a bracket c on the axle. The bracket c may have a longitudinal pivot b about which a sleeve on the axle turns when the axle tilts. A modification is described in which the spring u is connected to the upper end of a bracket similar to the bracket c and a second spring parallel to the spring u and pivoted or clamped to a bracket on the chassis is connected at its front end to the lower end of the bracket c. The pivot of the rocker arms may be placed above the spring instead of below and the two springs may exchange places. Fig. 8 shows the links h, i pivoted at their rear ends to a bracket fixed on the axle and at their front ends to the member c which swivels in a dumb iron a. In this case, the spring arm u may be replaced by a rigid arm connected to the axle through a coiled spring enclosed in a casing t. The Specification as open to inspection under Section 91 (3) (a) comprises also a modification applied to the rear axle as shown in Fig. 9 (Cancelled), and a construction of normalizing- device shown in Fig. 10 (Cancelled). The spring rocker arm u, Fig. 9 (Cancelled), is connected to a sleeve y, capable of rotating on the axle, by a shackle x pivoted about a pin x<2>. The sleeve y is connected by a single radius rod h<1> to a longitudinal pin l<2> capable of rotating in a bracket l<3> on the chassis. The normalizing- device is enclosed in an oil-tight casing comprising two end portions 13, Fig. 10 (Cancelled), and two central portions 13<a>, 13<b> bolted together and carried by brackets from the chassis. The rods z connected to the rocker arms extend into the casing and screw into plates 14, 14<a>. The effective length of the rods can thus be adjusted by screwing them into the plates 14, 14<a>, lock nuts z<2> securing them in their adjusted position. The plates 14, 14<a> slide on rods 16 which extend from end to end of the casing and are provided with plates 18, 18<a> at their ends. Springs 17, 17<a> with or without additional springs 17<b> (shown to the right of the Figure) within them are placed between the plates 14, 18, 14<a>, 18<a> around the rods 16. The rods 16 have abutments 19 between which and abutments 21 on the casing, springs 22 are interposed. Springs 23 passing through the abutments 21 and springs 22 extend between the plates 14, 14<a> and the abutments 19. This subject-matter does not appear in the Specification as accepted.
