ELECTRICAL MAKE-AND-BBEAK TRIPPING MECHANISM FOR TWO OR FOUR CYCLE GAS- ENGINES.
Application filed March 15,
To all whom it may concern: I
Be it known that I, MATTHEW H. Bon- LAND, a subject of Great Britain, and a resident of Seekonk, in the county of Bristol and State of Massachussetts, have invented a new and useful Improvement in Electrical l-vlake-and-Break Tripping Mechanism for Two or Four Cycle Gas-Engines, of which the following is a specification.
My invention relates to improvements in electrical make and break tripping mechanism for two or four cycle gas engines,- and the objects of my improvements arefirst, to obtain a positive electrical contact of igniter point; second, to give a positive release to the igniter mechanism, thereby obtaining a sure ignition to every explosive stroke of the engine inside of the cylinder, which increases the revolution and power of the engine.
I obtain these objects by the mechanism .illustrated in the accompanying drawings,
in which Figure 1, 1s a sideelevatlon of the whole tripping mechanism; Fig. 2, is a cross section of the mechanism shown in Fi 1; Fig. 3 is a front elevation of the mechanism; Fig. 4: is a side view of the trip block shown as 1 in Figs. 1, 2, and 3; Fig. 5 is a top View of the trip block shown in Fig. 4; and Fig. 6, is a side elevation of the engine.
Similar letters and similar numbers refer to similar parts throughout the several views.
Fig. 1 shows the tripping mechanism, and 1 is the trip block, 2, is stop-pin in plunger head of pump used in circulating water around the jacket of the cylinder which pin prevents the trip block from being forced out of plunger head by the spiral spring 4, 5 is a washer having a hole 6 through which screw 7 is inserted to hold spiral spring 4: in position. 8 is an air vent to allow trip 1 to slide longitudinally more easily. 9 is the hole in plunger head through which igniter spindle 13 is placed. In Fig. 2, 10 is the recess in plunger head into which the trip block 1 operates longitudinally. 11 in Figs. 4 and 5, is a square hole in the trip block through which the igniter spindle drops at the time of ignition. 12 in the samefigures show a lip in the trip block which when the trip block is moved longitudinally by the spiral spring 4, comes in contact with the stop pin 2 to prevent said Specification of Letters Patent.
1916. Serial N0.84,389.
trip block from being forced out of the recess 10 of plunger headv A. 13 is the ignition spindle, 14 is a lever for movable electrode, 15 is a spiral spring having a lifting power and 17 is a spring having a downward pressure on the ignition spindle, 16 is the trip timer and 18 is a collar on ignition spindle to hold spring 17 in position.
This trip block gives a positive contact of ignition points, and also a positive release to igniter mechanism. The trip block 1 is placed in the plunger head, then pin 2 is inserted. Trip block has a recess (see 3 in Figs. 4 and 5), into which one end of spiral spring 4 is inserted, washer 5 is then placed in position and screw 7 is then screwed on.
Plunger A, is then placed in bore of pump barrel F and through pump gland E. Eccentric rod G has a bore at one end to receive the small end of plunger head. This end of eccentric rod is held on the plunger head. by washer 5 and screw 7. The other end of said rod is attached to crank shaft D in an eccentric position, which gives the plunger the required stroke for circulation purposes movement in the plunger head.
Spiral spring 4 in plunger head forces I the trip block outwardly when the plunger A is lowered by the eccentric rod G. The pin 2 is so placed as to stop the outward movement of the trip block 1 so that the hole 11 in said trip block will stop half way under theigniter pin 18 in order that when plunger A is raised vertically by the eccentric rod G, the said igniter pin will therefore be lifted upwardly, and the trip block pushed inwardly into the longitudinal recess of plunger head by timer 16. When the trip block is raised at the proper height as regulated by the timer 16, the said trip block is pushed back into the plunger head a sufficient distance to allow the igniter pin to drop suddenly into the hole 11, thereby breaking the current and causing the spark.
The ignition spindle 13 and trip block 1 both have flat surfaces at the point of contact so that the Wear will come on each surface evenly.
Claims:
1. In an ignition apparatus for gas engines, a water circulating pump having a plunger, a transverse chamber in said plunger, a trip'block slidably mounted in said chamber, a spring for projecting the trip block outwardly from said chamber, a stop pin to limit the extent of outward movement of said trip block, an air vent co1nmunicating with one end of said chamber, to permit escape of air upon retraction of said trip block, an adjustable timer pin in the path of the projected end of said trip block, an igniter mechanism operated by said trip block and common means for operating said pump plunger and moving the trip block past the end of the timer pin. 2. In an ignition apparatus for gas engines, a trip block having a circular body, having a transverse bore therethrough, a shoulder or lip at one end adapted to engage a stop pin, a stop pin inserted crosswise in said chamber, and engaging the said shoulder of the said trip block, an igniter pin operating perpendicularly, and dropping through a bore of said trip block at moment of ignition.
3. A tripping mechanism for igniters comprising the plunger head of a Water circulating pump, of a slidable trip block operating longitudinally in the horizontal Copies of this patent may be obtained for chamber of the plunger head of the water circulating pump, means to operate said trip block longitudinally, consisting of a spiral spring inserted horizontally in said chamher and abutting one end of said trip block thereby creating a slidable outward movement of trip block, means to operate saidthe plunger of a pump, an igniter mechanism, a trip block mounted in said plunger, adapted to operate said igniter mechanism, stationary means for reciprocating said trip block, and common means for operating said pump plunger and moving said trip block into cooperative relation with said stationary means.
