ienrrroiv' DEVICE.

Application filed September s, 1917. Serial in. 191,933.

To all whom it may 00110 M:

Be it known that I, ARRYR. VAN VENTER, a citizen of the United States, re-' siding at Sumter, in the county of Sumter and State of South Carolina, have invented certain new and useful Improvements n Ignition Devices, of which the following is a specification, reference being had, to the accompanying drawing.

The invention relates to an ignition device for internal combustion engines, and more particularly to an ignition device 111- cluding electrodes, a magneto generator electrically connected thereto, and a tripped spring actuated mechanism for operating said generator. v

An object of the invention is to prov1de an ignition device of the above character with a two part supporting bracket, the generator being mounted on one of the said parts and the electrodes being mounted on the other pant.

Afurther object of the invention is to provide a two part supporting bracket of the above character, wherein the trip lever for actuating the springs which operates the generator is mounted on the part of the supporting-bracket carrylng the electrodes.

A still further ob ect of the invention is to provide a two; part supporting bracket of theabbve'charter with means for independently attaching and supportmg the bracket parts.

Another object of the invention is. to provide atwo-part supporting bracket, Wherein theadjacent faces are formed Withinterlocking connections so that the parts of the bracket. are held in a predetermined relation to each other.

These and other objects will in part be obvious and will in part be hereinafter more fully disclosed.

In.th,e drawings, which show by way of illustration one embodiment of my invention,--

Figure 1 is a side view ofa supporting bracket embodying my invention with the parts of the ignition device assembled thereon;

Fig. 2 is a front view of the same, with the magneto removed; and

Fig. 8 is a plan view of the supporting bracket with the magneto, the electrodes and the actuating mechanism removed therefrom.

make-and -break My invention consists broadly .in an ignition device which includes a two-part supporting bracket. ()ne of the parts of the bracket carries the ignition electrodes, while the "other part of the bracket carries the magneto generator. The generator is electrically connected to the electrodes. One of the electrodes is preferably movable for a ignition. The movable electrode and the flux shifting member of the generator are operated by a tripped spring actuating mechanism, and the trip lever of the spring actuating mechanism is mounted on the part of the bracket carrying the movable electrode. This trip lever is operated by the well known push-rod carrying a trip finger. The thrust ofthe pushrod against the tripper lever is borne by the part of the bracket supporting the electrodes and therefore there is no tem'lency onvthe part of the push-rod, when actuating the tripping'lever, to wear loose the section ,of the bracket carrying the generator. The

indicated at 2.- The part2 of the support ing bracket is provided with a sleeve, 3, which projects through the cylinder wall. The cylinder wall is indicated at C, in Fig. 1 of the drawings. The projecting sleeve 3, is preferably formed integrally with the part 2 of the supporting bracket. Mounted in this sleeve is a fixed electrode 4, and a movable electrode -5. These electrodes are providedwith

ignition points

6 and 7, respectively. The :electrodc 4 is properly insulated from the sleeve 3. The movable electrode at its outer end carries an arm- 8. A spring 9, hearing at one end against the arm 8 and at its other end' against an abutment 10, on the bracket 2, normally holds the ignition points in contact.

The part 2 of the bracket lies against the outer surface of the cylinder wall andis clamped in place by a stud bolt 11, on which a nut 12, is threaded.

pressed against the outer surface of the cylinder wall and is secured in place by two

stud bolts

13 and 14. The upper end of the bracket part 1, is slotted at 15, to receive the upper stud bolt, while the lower part of the bracket is perforated to receive the stud bolt 14. Suitable nuts 16, are threaded ,onto these

bolts

13 and 14 to clamp the bracket in place. The lower end of the bracket part 1, projects out from cylinder bracket part is formed with 20, which fit into the rethe bracket ger moves to the left as viewed in Fi .38, which electrode, causing the electrodes to separate and is formed with a horizontal shelf 1?. The generator which is indicated at G, is mounted on the shelf and is held thereon by bolts 18, which extend up through openings in the shelf and are threaded into the base of the generator.

As will be apparent'from Fig. 2, of the drawings, the supporting bracket is directed vertically to form the parts 1, and 2, and the adjacent faces are milled so as to form smooth contact faces. One of these faces is formed with recesses 19, while the other corresponding shaped projections cesses and hold the two parts of-the bracket in a predetermined relation to each other.

The generator and the movable electrode are operated by a spring actuated tripped mechanism consisting of a trip lever 21 mounted on a suitable supporting shaft 22, which is fixed to the part 2, of the supporting bracket. This tripping lever is provided with

pins

23 and 24. An actuating spring 25 engages a roller 26, on the pin 23,,

and also engages a roller 80, on a pin 31, carried by the upper end of the bracket part 2. An actuating spring 32 engages a roller 33, on the pin 24 and also a roller 34 carried by the projecting lug 35, mounted on part 11, adjacent the shelf 17, which supports the generator. These actuating springs normally move into alinement.

The tripping lever is formed with a shoulder 36; which is adapted to be engaged by a trip finger 37, carried by the push-rod which is operated by the engine. As the trip fin- 2, it will move the trip lever in a clockwise tion until a certain position or point is reached when the trip finger slips from the shoulder and allows the springs to return said trip lever to normal position. The trip'l'everjs provided with a cam shoulder strikes the arm, 8, on the movable and produce a spark. The generator is provided with a forked arm 40, which engages the pin of the trip lever so that this movement of the trip'lever through the action of the springs also quickly shifts the fiux shift ing member of the generator. duces the current'for ignition.

This pro- From above it will be apparent that the thrust of the push finger on the tripping lever and the jar incident to the actuation of the springs is borne by part 2 of the sup direcraaaoeo porting bracket; and therefore there is no tendency to loosen the supporting bolts car rying the parts 2 of the bracket which supports the generator. I Furthermore,the part of the supporting bracket which ,projects out from the cylinder and carrying the gen;- erator is more liable to be broken than the other part of said bracket. If the shelf carrying the generator i'sbroken, it is only necessary to remove and replace part 1, ofthe supporting bracket. Then again, as all the strain is carried by part 2 of the supporting bracket, it may be made of cast metal of heavy construction, whilepart of the SUIT-1", porting. bracket may be made of stamped metal, and thus the cost of manufacturing the supporting bracket greatly reduced. It is obvious that nrinor changes in the details of construction and the arrangement of the partsmay be made without departing from. the spirit ofthe invention as set forth in the appended claims:
