Title: Improved pivot-joint particularly suitable for wind-screens of vehicles
IPC: B60J1/04
Filed: 1919-03-07
Abstract: 141,473. Harrison, W. W. March 7, 1919. Pivot adjustments.-An adjustable joint for wind-screens of vehicles, of the type comprising an expansible band revolubly carried by one memoer applied within a bore on the other member and adapted to be expanded into frictional engagement by a wedge-piece forced between the inclined ends of the band, has the expansible steel band c approximately equal to the length of the boss a<2> with its ends c<2>, c<3> thicker than the middle portion c<4>, the inclined faces c<5>, c<6> of the ends converging toward the centre of the boss. The wall of the boss is thin, and this feature, together with the further cutting-away of the slot a<4> to provide the limits of adjustment of the screen, produces additional gripping means as the boss itself is frictionally gripped within the bore e<2> of the other member e. The wedge-piece d is inclined to fit between the ends of the expansible band, and is forced into engagement therewith by the tightening-bolt f. The wedge-piece also acts as a key to connect the two members through the expansible band. A side plate g with bolt h encloses the joint.

IPC: F02P5/07
Filed: 1916-04-18
Abstract: 101,070. Kennington, W. O. April 18, 1916. Timing.-Apparatus in which a fall of pressure in the induction pipe automatically advances the igniter upon increase of speed is provided with means for automatically retarding the ignition when the engine is idling. The plate H carrying the timing-contacts F, G is rotated against the action of a spring 0 by the piston L, which is in communication with the induction pipe. Under the high suction which obtains while the engine is idling, the throttle valve D either moves to obstruct the openings of the pipe N or moves beyond the opening so that the piston L is not subject to the increased suction. In the former case, a small perforation a puts the pipe N in communication with the outer side of the throttle. The throttle D may be linked to a valve in the pipe N, the throttle and the valve closing synchronously. The device may be combined with a centrifugal governor for adjusting the cam for operating the contacts F, G.
