IPC: B60J1/14
Filed: 1930-04-25
Abstract: 341,813. Vehicle windscreens. ROBINSON, A. P., 600, 8th Avenue North, Seattle, Washington, U.S.A. April 25, 1930, No. 12840. Convention date, Oct. 3, 1929. [Class 103 (ii).] For preventing the entrance of dust and wind through the window opening on a vehicle body or door fitted with a slidable drop window when the latter is in, its lowered position, a deflecting vane or wing is supported in an inclined position adjacent to one edge of the window opening and is adapted, in its inoperative position, to be stored within the casing or recess which receives the lowered window. In. the construction shown in Figs. 1 and 2, the deflector 3 is of a dismountable character, being supported in its operative position in sockets 34 at the top and bottom of the window opening and held at the desired inclination by pivoted flaps 37, while in its inoperative position it is disposed in sockets 33 in an independent pocket 17 adjacent to the door pocket or casing 1 that receives the sliding window 2. In a modification, Figs. 4 and 5, the deflector 3 slides within a vertical guide or tube 4, and in its lower position is disposed within the same storage space. 11 as the window 2, the latter entering the space 11 through one slot 121 in the window sill 12, while the deflector 3 enters by way of a separate slot closable by a cover 18. The deflector 3 is held in its lower position by means of a locking dog 40 which, when released, allows a spring 45 to project the deflector a small distance out of the space 11 so that it can subsequently be raised by hand. Further modifications are described in which operating mechanism is incorporated for effecting the displacement of the deflector through its entire travel, and in which the deflector is arranged to enter the storage space through the same slot as the window 2, the latter object being attained by causing one edge of the window to be displaced laterally in its extreme lowered position, thereby providing a space for the accommodation of the deflector.

Title: Improvements to fuel pressure regulators for internal combustion engines
IPC: F02M37/00
Filed: 1931-05-01
Abstract: 378,038. Pressure-regulating valves. SOC. GENERALE DES CARBURATEURS ZENITH, 26, Rue de Villiers, Levallois- Perret, Seine, France. May 1, 1931, No. 12935. Convention date, May 1, 1930. [Class 135.] A fuel-pressure regulator for internal-combustion engines comprises a fuel passage, a valve for controlling said passage, flexible membranes subjected to pressure on the inlet side of the valve, others subjected to the pressure on the outside of the valve, and means for connecting said membranes to each other and to the valve. The object is to eliminate the effect of the inlet pressure on the valve by producing an opposing substantially equal force. The fuel, the pressure of which is to be reduced and regulated, is supplied through a conduit 1, Fig. 1, to a chamber 2 whence it passes a valve 4 to chamber 3 and outlet 7. The chamber 2 is closed by a membrane 10 the effective area of which is equal to that of the inlet side of valve 4. Regulation is effected by a membrane 5 which may be loaded by a spring 8. The valve and membranes are interconnected by a rod 6. In a modification, Fig. 2 (not shown), the membrane 10 is connected to the valve through a lever, so as to permit of a larger membrane being employed. Larger membranes may also be employed by utilizing a differential action between balancing membranes 12, 13, Fig. 3, the effective surfaces of which have a difference equal to the surface of the inlet face of valve 4. The inlet pressure is transmitted by a duct 115 to opposed faces of the membranes 12, 13 the other faces being subjected to atmospheric pressure or to other constant pressure such as that of the fuel outlet. The valve, the membranes 12, 13 and the regulating membrane 5 are interconnected by a rod 15, and loaded by a spring 8. In a modification, Fig. 4 (not shown), one of the balancing membranes is subjected to the pressure of the issuing fuel and a lever connects the rod 15 with the valve. In a modification, Fig. 5, one of the balancing membranes 13 is subjected to the pressure of the outlet fuel conveyed to a chamber 21 by a duct 22. Inlet occurs at 1, and outlet at 7, the valve 4 being connected to rod 15 by a lever 20. In a further modification, the lever is omitted. Other modifications consist (1) in combining the membranes 13, 5 of Fig. 3, the compartment 17 being dispensed with, Fig. 7 (not shown) ; (2) in combining the membranes of Fig. 4 (not shown) ; (3) connecting the valve directly to the balancing membranes and through a lever to the regulating membrane, Fig. 9 (not shown) ; (4) giving to the incoming liquid a certain speed by forming the diaphragm 19, Fig. 10, so as to approach the diaphragm 13 ; and (5) transmitting the pressure of the loading spring 8, Fig. 11, through a bellcrank lever 52, 53 so as to reduce the movement of the spring and maintain a more uniform load on the membrane. The space above the membrane 5 is connected by a duct 55 with the air intake of the carburetter being supplied.
