Title: Leveling valve mechanism
IPC: B60G17/052
Filed: 1957-10-17
Abstract: 859,094. Road vehicle spring suspensions; adjusting vehicle height. BORG-WARNER CORPORATION. Oct. 17, 1957 [Oct. 29, 1956], No. 32516/57. Class 108(2). Valves mechanism for controlling the inflation of vehicle pneumatic suspension springs 39 (Fig. 2) comprises a valve body 52 (Figs. 4 and 5) in which is an inlet valve 62 connected with an air reservoir 50 and an exhaust valve 63 adapted to be actuated by a lever 60 having a limited travel in the body 52 and mechanical connections for actuating the lever 60 which include a resilient arm 102. The spring 39 is in the form of pneumatic bellows the lower end of which is connected to the upper wishbone link 38 of an independent suspension for a front road wheel 34. The upper end of each spring 39 is connected by tie rods 44 to a transverse frame member 13. The valve body 52 is connected by a conduit 99 with the interior of the upper end of the spring 39 and the arm 102 is connected by a link 103 with a member 104 rigid with the part of the spring 39 connected to the wishbone link 38. The other end of the arm 102 is connected to a shaft 53 which is rigid with the lever 60 and also carries a vane 55 which is positioned in a dashpot housing 54. The vane 55 may be loose fit in the housing 54 or may be formed with a liquid flow notch 55a. The dashpot liquid may be a silicone of the composition described in U.S.A. Specifications 2,469,888 and 2,469,890. Expansion of the liquid may be provided for by a space 57 and/or by provision of an axially-slidable shaft packing ring 58. The valves 62 and 63 have respective stems 80, 95 adapted to be engaged by the lower end of the lever 60 when it is moved in the appropriate direction from the normal position shown. These valves are conventional vehicle tyre valves. As shown the arm, 102 comprises respective end members of sheet metal joined by a coil spring which is so pre-tensioned that its coils are normally in tight engagement. In operation, as the road wheel 34 moves up and down under changing dynamic loads, the link 103 moves in correspondence with the wheel 34 and acts on the arm 102. The lever 60 is unable to move with the rapidity of the movements due to the changing dynamic load due to the action of the dashpot 54, 55, the movement of the rod 53 being taken up by flexing of the coil spring of the arm 102. On a change in height of the road wheel 34 for a longer period of time, the load imposed by the flexed arm 102 upon the dashpot 54, 55, asserts itself and the lever 60 is displaced to act on the stem 80, or 95, as the case may be. In a modification (Figs. 12 and 13, not shown) the arm 102 may be formed by two leaf springs of curved crosssection. Due to the effect of the curvature the the leaf springs resist bending up to a predetermined degree of initial load. The rear suspensions are controlled by a single valve mechanism acting between the vehicle frame and a connection to a normal differential and axle housing.

Abstract: 506,802. Toys. ULLMANN, P. Dec. 2, 1937, No. 33348. [Class 132 (iii)] A toy has a clockwork motor unit slidably mounted on the axle of the main running wheels, a rotatable or noise producing device or devices, and means actuatable by an operating lever on the toy, whereby the unit can be slid on the axle to lock or brake the motor and to couple or uncouple the motor with or from the rotatable or noise producing device or devices only, or with or from said device or devices and the axle. In the embodiment shown, the clockwork casing 2 of a toy aeroplane has pivoted thereto a depending plate 19 and a lever 23, with a cam slot 24 which engages a lug 20 on the plate 19 for moving it into each of the positions shown. The projection 19d locks the star wheel 10, which is geared to the motor to prevent drive being transmitted through the shaft 8, gears 9 and 12a, shaft 12, rollers 13 and discs 14 to the propellers. In the middle position of the lever the star wheel 10 is released to drive the propellers, but the projection 19b still holds the gear 17 away from the star wheel 10. In the upper position of the lever, the projection 19b causes the engagement of the star wheel 10 and the gear 17, so that both propellers and driving wheels are rotated. The motor is governed by a double-pawl which has an extension which simulates exhaust noise by beating against the casing. In a modification, the plate 19 and arm 23a are formed in one piece having a detent or pip to engage in three grooves or recesses in the front of the casing 2. The invention may be applied to a fire engine in which the bell is rung before and after starting.

Abstract: 430,964. Guards for penholders. LONGO, L., 46, Via dei Pontefici, Rome. Nov. 20, 1934, No. 33414. [Class 146 (iii)] A penholder is provided with a spring- actuated shackle ink guard of shield form maintained by the spring in a forward position near the nib-end of the penholder, and thus serving to determine a constant position of the fingers of the user. The guard 4 is pivoted to a spindle 5 which slides in slots 3 in the penholder 1 so that it can be pushed back, when the pen is dipped, against the action of a tension spring 7, or of a compression spring placed behind the spindle, the spring being housed in the recess 2 which is somewhat deeper than usual. The ends of the spindle may be screw-threaded, so that the guard may be readily removed after unscrewing nuts on the spindle ; the spring has an attached perforated plate fitting on the spindle. The guard prevents the writer from gripping the pen too near the nib, and by its pivoted mounting adjusts itself to inclined positions to accommodate the fingers. The portion of the penholder behind the guard is smooth and rigid. In an alternative form, adaptable for very thin penholders, the guard is pivoted to a sleeve to which is secured a spring housed within a second sleeve fixed to the penholder ; or an ornamental guard is fixed to the first sleeve instead of being pivoted, for use with a decorative penholder.
