Title: Improvements relating to motor vehicles having internal combustion engines
IPC: B60T13/24
Filed: 1928-07-09
Abstract: 293,693. Huessy, W., (Assignee of Trachsel, E.). July 9, 1927, [Convention date]. Controlling different functions by same handle or lever; relay or power apparatus. - Motor vehicle brakes and engine, clutch are connected by a rod to a spring restrained by .vacuum in a vessel connected to the engine suction pipe, the vacuum being adapbed to be lessened in order to release the spring to its full or to a lesser extent. The control pedal in the first part of its movement acts as an accelerator, in the second part as a clutch control, and in the third part as a brake control. At the beginning of the second part of its movement a catch on the pedal engages a catch on a lever connected by a rod 19, Fig. 1, to the lever 24<a> of the clutch and brake control valve 33, which it, opens by means of an eccentric 24, Fig. 2, to admit air into the vacuum vessel 1 and thus allow the spring 3 to move the clutch and brake-operating rod 6 carried in bearings 7, 8. A lever 11 thereupon slips out of a slot 10 in the rod 6 and slides on the underside thereof thus withdrawing the clutch by means of a lever 14 and a rod 15. A bolt 37, Fig. 3, is likewise operated by the lever 24a, link 25, and lever 26 and cam means so that it presses against the rod 6 and then falls into a catch 38 on the rod 6 to maintain the position of declutching. Movement of the lever 11 also recloses the valve 33 by means of a second eccentric 23 connected to the lever 11 by lever 23<a> and link 27, thus restoring the vacuum. If the control pedal is moved back through the second part of its movement the bolt 37 is withdrawn from the catch 38 and the clutch is again put in engagement by the restored vacuum. When the control pedal is moved in the third part of its movement the valve 33 is again opened : at the same time however the catch movement of the rod 6 is released whereon the rod 6 moves to apply the. brakes. On release of the clutch pedal there follows consecutively the release of the brakes, and the engagement of the clutch, due to the closing of valve 33 and the restoration of the vacuum in cylinder 1. The cylinder is connected to the engine suction pipe by a pipe 28 provided with a regulating valve under the control of the driver.
