IMPERIAL

PATENT OFFICE.

This regulating device is drawn in Fig. 1 in section MN, in Fig. 2 in section XY and relates to a modification of the construction according to patent - claim 1 of patent no. 48902.

From the main shaft of the engine, as in the other constructions, which work with four-stroke, the former is at half the speed of that on shaft 0? ² seated rotatable gearwheel ^ set in rotation. Shaft i ² is mounted in bracket b , which is attached to the side of the motor. The hub of the gear wheel \ is with the two staggered eccentrics and cams η and w ¹ is provided, the former of which by means of their f to shaft i ² concentric slot and screw m adjustable about the hub, is to determine the case, the moment for the purpose.

As in the main patent, is v to d ¹ lever i with roller and notch w, which c by the linkage with the exhaust is in communication, rotatable, as by d ^3, the angle of pawl ρ g, which the apparent from Fig. 1 Form receives. Lever r is influenced by cams η ^x , while angle pawl pg, whose movement is limited by pin g ^l and the adjustable pin g ^{2 of} the bracket, on the one hand by the spring g ³ , which exerts a pull in the direction of the arrow, and on the other hand by the The pendulum α suspended at h is influenced, the base of which α ² rests on the cam η in the idle state. Pendulum α can be shifted a little by means of nut α ² on the pendulum rod, and a ball can also be moved on the upwardly extended pendulum rod for the purpose of regulating the pendulum.

Approach α ^{1 of} the pendulum is somewhat elongated laterally and provided with a leaf spring α ³ , which rests on the angle pawl ρ in the rest state.

When working, the cam or the eccentric η continuously influences the pendulum a at its base and moves it in such a way that, during normal operation, the pawl, on which spring g ^{3 has come} into effect, is pushed back into its normal position by the base of the pendulum. If the pendulum moves too quickly, it is thrown more strongly outwards, so it has to travel a longer way back and as a result does not follow the upward movement of the lever r , with the result that the lower arm of the angled pawl, which tapers to a point, moves into the notch w of the lever r inserts and in this way keeps the exhaust valve open until the normal number of revolutions is reached again.

The purpose of the leaf spring a ³ , when the pendulum falls back, when the angled pawl has sunk into the notch and so the laterally elongated attachment a ^{1 of} the pendulum would no longer reach the eccentric η , is nevertheless a contact of to achieve the correct movement. To achieve approach and eccentric.

The leaf spring slides over the outer tip of the pawl ρ by compressing it.

Claims (1)

Pa te nt-A ns p Ruch :. On the regulation for gas engines protected by patent No. 48902, claim 1, instead of the counterweight e, the arrangement of a correspondingly suspended and regulated pendulum a, which is thrown outward by eccentrics or cams η , and the resilient angled pawl by means of its extension α ^{J when going back} returns to its original position, while with an increased number of revolutions the latter has already inserted itself into the notch w before the pendulum a, thrown more strongly outward, has fallen back completely, in order to keep the pendulum in constant contact with cams η after the relapse , Approach a ^x with the leaf spring a ^{B is} provided. For this purpose ι sheet of drawings.
