Application filed march 12, 1908. Serial No. 420,538.

ToaZZ whom it may concern:

Be it known that l, JONATHAN D. Max- WELL, of Tarrytown, New York, have nvented certain improvements in Sparking Devices for- Explosive-Engines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings des gnating like parts.

This invention relates to sparking devices for explosive engines and is of particular utility when applied to electrical sparking devices for automobiles, although I Wish it understood that Icontemplate the use of my inventionin any field for Which it may be adapted by the nature of my improvements.

The object of my invention is to render the sparking generator quickly and easily removable from the explosive engine, and also to permit its return to operative position, Without disturbing other parts, and 1 preferably construct the closure member of the crank chamber asone part with the surfport for the sparking generator, the who and removable as a unithe frame carrying the cylinders, and

being mounted on, tary structure from, valve motion for the engine so from the engine.

The variousi'eatures of my invention will be illustrated and described fully in the accompanying drawin s and specification and pointed out in the claims.

In the drawings, Figure 1 shows, in vertical, longitudinal section, part. ct an explosive engine, with enough oi a crank chamber, its closure and sparking mechanism, in-thc-construction of Whichmy improvements have been embodied, to illustrate my inventiomvand Fig.- 2 isa view in perspective,

. place upon an automobile.

In the embodiment of any invention selected for illustration and description to enable ready and com lete understandin of. my improvements, ,1; e part. designate by the reference numeral 1 isan 93.26513071116- chanical spark, generator, which maybe of any convenient and suitable-construction, roir admit-h,electricalconductors Q-oit' ,rv ich portions only are shown and ,Which ,may extend tothe sparking plugs 3 (see Fig. 2) directly or through =contrclling ,mechanism at any desired part ,of the apparatus, the sparkgenerator having anactuating shaft mounted .in bearings a and 6 formed. re-

of the parts shown in Fig. l, in

'28, y from which spectivelyin the stationary part 7 and removable face plate S of a casing provided for a gear or other actuating member 9, which, in the instance illnstratedfmeshes with a gear 10, fast upon a cam shaft The faceplate 8 may have suitable fastening means, such as the bolts 12, to secure it in place. I

The clectro-mechanical sparking device 1, in accordance with my invention, is mount-, ed upon, and removable as a unitary structure with, a member 13, suitable fastening means, as the cap screw 26,- beingprovided preferably, to secure the generator upon the member '13, which serves 'as I a-closure for the crank chamber 14:, over a hand-hole, or opening 15 in the crank chamber, to the sides of which may be bolted in usual fashioncylinders 16, provided with suitable valves 17.

5T0 actuate these valves have illustrated cams 18 engaging spindles/19 carried in bearingsQO, extending through, and preferably forming a part of the Walls of, a frame 21, this frame with the .valvespindles being removably secured ,over the upper aperture of the crank chamber 14 by suitable fastensing means, as the bolts 22 which project through the edges of the closure 13 also, and have nuts 23 to retain the several parts in assembledrelation, ,lt vvillthus be seen that when access to the crank chamber is desired, the sparking generator 1 and the closure 13 can be removedas a unitary structure simply by removing the nuts 23 andif desired the frame 21min be removedthereafter, carrying with it the camshaft 11,.and-

this shaft inlturn can be removed irom its bearings 2% and 25 and, the spindles 19 .from their bearings20wvheninecessary.

ll donot claim -generically as aieature of my present invention the frame 21,,removable with the cam shaft and spindles, ,as the sameforms thesubject matter of my ggipligg tion Serial No. -,3 75,5v 72, ,filsd lllhegear 10 upon the cam shaft meshes with a gear 27 est, upon the crankshaft is derived the power torotate the cam shaft .11 .and the operator shaft i, and it will be observed it teach of .theselshafts and their corresponding gears coinelaway together, and remain asso ciated, sothat they lean be; readily assembled reason, 1 the closure and the valve frame have been removed.

Having described my invention thus fully and convenient means for carrying the same into efiect, it will be understood that I do notlimit'myself to the specific form n paratus selected for illustration, :2 J eral otherwise than as set fort ix. read in connection with the vcilication.

What I claim and desire 2.1) secure by Letters Patent is 1. The combination with an explosive engine, its crankshaft, and a casing therefor having a removable cover-part; of a spark generator having stationary and rotatable elements, said generator being mounted on,

and removable with, said cover part, with-.

out altering the relative position of the generator elements; and means to permit action said crank shaft, substantially in the manner and for the purpose set forth. Y

2. Thecombination with an explosion engine, its crank-shaft, and a casing therefor having an opening opposite said crank-shaft,

of a cam-shaft, and its bearing sup ort, said I opening bearing support surrounding sar casing; a 010- and being mounted upon sai sure for said opening; a spark generator mounted on, and removable bodily with, said closure over said cam-shaft support; gearing connecting said cam-shaft with, and to operate, said generator; and means to permit actuation of said camshaft and said generator by said crank-shaft, said actuating means being subject to splash lubrication from said crank-shaft; substantially as described.

3. The combination with an explosion engine, its crank shaft, and a casing therefor having an" aperture; of a removable valvegear-case having substantially strai ht Walls constituting an extension of sai easing around said aperture; a cam-shaft and cooperating valve-actuating members mounted in and removable with said valve-gearcase; a closure member mounted over said valve gear-case and aperture; an electromechanical spark generator carried by said closure member; a gear on said valve cam shaft, connected operatively with said generator; and means to permit actuation of said generator by said crank shaft, substan-' tially as described. 7
