Patent GB-290617-A (GB)
Title: Improvements in or relating to spring suspensions particularly for motor vehicles
IPC: B60G17/02
Filed: 1928-05-16
Abstract: 290,617. Houdaille, M. May 17, 1927, [Convention date]. Springs, arrangement of.-In a method of modifying the action of a spring according to the load, a two-armed lever is pivoted on the frame or the axle, one arm of the lever being connected by a link to the spring and the other arm to the axle or frame. In the construction shown in Fig. 1, two springs 1, 2 are each pivoted at their centre to a support 11 rigid with the axle. The outer ends of the springs are connected by shackles 3, 6 to the frame 4 and their inner ends are connected by links 15, 16 to the short arms 19 of the two-armed levers 19, 21 pivoted to the support 11. The long arm 21 of the levers are connected by links 22 to the frame 4. As the frame and axle approach one another due to increase of load or road shocks, the link 15, 16 and arms 19 tend to move in line as shown in dotted lines. Over this range of movement, the linkage automatically increases the normal flexibility of the spring, but further approach of the axle and frame decreases its flexibility. In a modification the arms 19, 21 are arranged at an acute angle to one another, so that the normal stiffness of the springs is increased as the frame and axle approach. The inner ends of the two springs may be brought closer together so that the links 15, 16 may both be connected to a single angle lever. The inner ends of the springs may be pivoted to the support 11 and the centres will then be connected to the angle levers. In the application to a cantilever spring shown in Fig. 5, the forward end of the spring is connected by a link 17 to the short arm 21 of the angle lever 19, 21, the long arm 19 being actuated according to the relative movement of frame and axle through linkwork 32, 31, 29. In a modification the front end of the spring is pivoted to the frame and the middle is connected to the angle lever. In further modification two springs are arranged transversely.

Abstract: 253,546. Maatschappij tot Vervaardiging van Snijmachines Volgens van Berkel's Patent en van Andere Werktuigen. June 11, 1925, [Convention date]. Cutting slices in succession. - In a. slicing- machine, the clamping-bar has double-action locking-pawls or levers which come automatically into action against the usual upright guides (a) when the clamping bar is pressed down to grip the meat, the reaction of the meat causing the pawls to lock the bar in position, and (b) when the clamping bar is raised out of contact with the meat, the weight of the clamping bar causing the pawls to lock it again in place and prevent it from slipping downwardly on the uprights. In Fig. 1, the clamping-bar 12 is pivotally connected to sleeves 3, 4 slidable on smooth uprights 1, 2 and pawls 7, are pivated at 9, 10 to the sleeves which are slotted to allow the pawls to engage the uprights. The bar 12 is pivoted at 16 to the pawl 7 and, at the other end, is pivoted at 13 to a link 14 pivoted to the pawl 8. The pawls 7, 8 are acted on by springs 23, 24 which assist in locking the bar in position when it is inoperative. The operative faces of the pawls have upper and lower protuberances 17, 18 as shown, the pawls being rocked by the upward pressure of the meat to engage the upper protuberance with the uprights, the reverse motion occurring when the bar tends to fall under gravity. The pawls are released by raising the sleeves 3, 4 by the handles 6.
