Title: Improvements in or relating to spring suspensions for motor and like vehicles
IPC: B60G21/04
Filed: 1924-10-27
Abstract: 248,027. Adye, J. F. Oct. 27, 1924. Springs, arrangement of; equalizing load on springs and wheels; guiding vertical play.-Relates to spring suspensions for motor and like vehicles in which a cantilever spring is associated with each wheel, and the axles or springs are interconnected by tie-members and rockers so that a displacement of one wheel relatively to the frame causes a displacement in the opposite direction of the other wheel on the same side of the vehicle. The tie-members and rockers are so disposed that the movement imparted by one wheel to the other is progressively reduced as the upward displacement of the first mentioned wheel is increased so that the suspension system tends to return to the normal position. As shown in Fig. 1, the axles 11, 12 are carried by single leaf or laminated springs 13 fixed to the frame 10 and the axles are connected by tiemembers 16, 18 which are connected to the frame by flexible or pivoted rockers 17 arranged so that their effective arms are inclined in opposite directions. The tie members may be resilient and the members 18 may be connected at 19 to a rocker arm 20 which may be connected by a cross-shaft to a similar arm on the other side of the vehicle so that the suspensions of all the wheels are interconnected. A pivotal joint at the connection of the parts 16, 17 and 18 may be avoided by flattening the ends of these parts and bolting them together. In the modification shown in Fig. 4. full cantilever springs 53, 54 are utilized. The inner ends of these springs are connected by shackles to the arms 57, 58 of a lever which is pivoted at 54 to the frame and may be connected by a cross-shaft to a. corresponding lever on the other side of the frame. The arms 57, 58 are inclined to one another and to the shackles. The rocking lever may also be controlled by a flat spring 611 to increase the stability of the system. In another modification employing pivoted cantilever springs, the inner arms, which may be rigid, are inclined downwardly in opposite directions similarly to the members 17, Fig. 1, their ends being connected by a tie-member. When the springs are provided with rigid arms, one leaf of such a spring may be extended beyond the pivoted connection of the spring to the frame, the extension being shackled to the frame. A lever with inclined arms similar to 57, 58, F'ig. 4, may be used to replace the arm 20, Fig. 1, the arms being respectively connected to one of the tiemembers 18. Pivoted radius rods may be provided to guide the movement of the axles or, as shown in Fig. 4, a leaf spring 60 may be used for this purpose. Also, in the arrangement shown in Fig. 1, springs similar to the springs 13 may be arranged parallel thereto and secured to the undersides of the axles.

Title: Improvements in or relating to hydraulic shock absorbers
IPC: F16F9/28
Filed: 1938-09-07
Abstract: 517,109. Vibration-dampers. ARMSTRONG, F. G. G. Sept. 7, 1938, No. 26122. [Class 108 (iii)] The invention relates to an hydraulic shockabsorber for motor vehicles wherein resiliently loaded valve means regulate flow between a pair of piston chambers in separate or a single cylinder or between chambers separated by a rotary vane. An orifice is formed in a movable part of valve means or as at.3, .Fig. 2, between relatively movable parts of valve means 26 to form a permanent passage of small section between piston chambers 18, 19, Fig. 1, so that any dirt tending to plug up the passage is removed by movement of the valve &c. The small passage may be merely a clearance between valve spindle and a slidable disc 28 or may be a flat on the spindle or a notch, groove or the like. In operation, a large angular displacement of a crank 11, Fig. 1, a piston 16 compresses and a piston 17 sucks. Oil is forced through passage 21, bore 20, ports 30 in a valve 26 so .as to displace a washer 28 downwardly against a spring 32. The oil escapes by bores 24, Fig. 2, passage 22 into the other piston chamber 19. Large displacement of the crank 11 in the opposite direction raises the valve 26 against a spring 31 and allows oil to pass to the chamber 18. As the springs 31, 32 may be of unequal strength, greater resistance may be provided to movement of the crank in one direction. When small movement of the crank takes place insufficient to displace the washer in the valve, the permanent passage 33 is available for oil to flow between passages 21, 22.
