Specication of Letters Patent.

Application filed March 30, 1904. Serial No. 2(103667.

To all whom it may concern:

Be it known that I, OLIVER E. Bannon., a citizen of the United States of America, residing at Detroit, in the Icounty of Wayne and State ot' Michigan, have invented certain new and useful In'iproveinents in llxplosivelngines, of which the followingr is a` specification. reference being had therein to the accmnpanying drawings.

This invention relates to new and useful improvements in explosive engines and refers more particularly to that ty )e 'known as the multiple cylinder opposed type of gasolene engine.

'l`o this end the invention consists in certain new and useful improvements in explolsive engines and in the peculiar construction.I arrangement and continuation of parts all as4 more fully hereinafter described and pointed out in the claims, reference being had to the '.n-couxpanying drawings, in which Figure 1, is a plan view of my improved engine. one-half being shown in horizontal section on the line A-A Fig. 2; Fig. 2. is a side elevation thereof, one-half being shown in vertical section; Fig. 3, a vertical section through the crank case and adjacent parts on the line O O, Fig. 2. .1s shown in the drawings, 1 is thc crank case preferably cast in one piece, 2 the cylin ders integrally formed with the cylinder head 3, valve chamber 4 and surrounding water jacket 5 so as to do away with all ground and leaky joints.

6 is a flange extending around the inner end of the cy indcr and 7 are t'ap bolts passling through apertures in said flange into the Wallof the crank case to secure the cylinders in place at the opposite ends thereof; although if desired the method of splittingthe crank case in half and casting one-half with each cylinder might be used.

8 is the crank shaft 'mounted in bearings 9-10 removably secured to the opposite sides of the crank case by tap bolts, one or both Sides of the crank case being vertically siitted at this point so that. the crank shaft may be readily lifted out for the purpose of repair. Integrally formed with the bearing 10 is a housing l11 for the two to one gears 12, 13 mounted upon the crank shaft 8 and cam Shaft 14 respectively.

15 is the fly wheel secured upon the tapered portion of the crank shaft by the nut 1G and 17 is an extension of said shaft forming a cap for said nnt.and removably secured in position by the studs 18 so that either section of the shaft may be dislnounted without disturbing the other.

19 are the pistons, 2O the rodsc'onnecting the crank pins with'their respective pistons through thtI lnediuln of the transverse piston pins 21,

22 are channels or oil receptacles in the upper sides of the col'inecting rods Q0 formed with overhanging ledges and having an aperture :'23 at each end through which lubricant 'may be fed to the crank and pist/on pins respectively, the channels Q2 being preferably Iilled with wicking to prevent the oil from being lost or spilled in the operation of the partsl as it drops from the openingr Q4 in the cylinder casting eonnected'witb the luln'icator, not shown` l5 is a4 feed tube carried byV the piston adapted to register with the openingr 211 in the cylinder on thc return stroke of the pis ton. and conduct the lubricant to the oil hole 2V in'thc .sleeve of the connecting rodand to the piston pin to thoroughly lubricate the same. so that with but the one opening in the cylinder I :un enabled to maintain a constant lubrication oi the piston. crank and piston pins which is a decided advantage.

27 is the inlet passage controlled by the y on the valve stems through the medium of the inlet` and exhaust levers 36, 37 pivotally mounted on the brackets and carrying the anti-friction rollers 38.

39 arel coil springs sleeved on the stems of the inlet and exhaust valves to hold them normally to their seats and. 40 are openings in the cylinder casting opposite the inlet and exhaust valves for the purpose of the removal of the valves should it be necessary y to replace the valves or rcgrind the seats, at

the same time forming a convenient means for Golfingr the passages. 41 are screw plugs or bushes closing said openings, one of said bushes having ,an internally screw-thread 1.7 are removable covery for the it'. i# a governor weight pivoted on the 1 ram allait H and connected h y a link 4T with the ronnnnlator ltn `eplinell on the Shaft and carrying thc inclined contact strip `rif) adapted to make and llreak contact with the hrnxh 5U "ari-ital hy the 'frame but insulated therefrom and to which brash one terminal of the primar)Y circuit. is connected, the other i lealihng troni the upper edge thereof to the living' grounded on the frame.

5l is a spring to noi-mall)r hohl the gin ernor weight in the position shown lint as i the Speed of the engine inurezwes the eight ghi angles i will tend to elraighten ont at to the cani shaft due to the eentrifng-.ll force and automatically advance the lead of the l [iark by Sliding the con'nnntator on the shaft so that a more advanced portion of the rontaetielrip 49 n'ill n'lake and break contact with the lirnah, earlier. There it is desired however to check the engine down considerably, as in going through crowded thorough i'ares, l have pivoted a lever .3Q on the frame member` the upper end being conveniently eonneeted for the operator and the lower end to the sleeve' 53 on the cani shaft.

In the drawings the motor is shown as suspended from the frame of an automobile by the tap bolte'-l Screw threaded into bosses on the cylinder castings by which method of enpension l ain enabled '1.o use standard forms of bars.A as ordinarily carried in stock without` the necessity of bending into special forms. l

Havinor thus fully described )ny invention. what I e aini is l. In an explosive engine of the opposed f t vpe, the combination with the cylinders, the

pistone in Said cylinders, the crank, and the connectlng rods; of a crank case formed 1n one piece with an opening in each side for the reception of the crankshaft and with a lot leading to one of said openings Ihroagh which slot the crank may be inY sorted, and e plate to close the slot when the crank is in place.

2. In an explosive engine of the opposed type. the combination with the cylinders, the pitone in Haid cylinders, the crank, and the connecting rode; of a crank oase formed in one piece with an open top and an opening in nach eide for the reception of the crankhal't and having a vertical slot in one side opening therein through which the crank may he inserted`r a cover to close the top of the rae@l and a plate to eloSe the slot.

25. ln an explosive engine of the .opposed type. the eomhiimtion with the cylinders, the pistons in Said cylinders. the crank, and the connecting rods; of a` crank case formed in one piece to which the cylinders are Secured and provided with an open top and an opening in each side and a 'elet leading frointhe upper edge of the side to the open` ing' therein, detachable bearinge for the crankshaft adapted to he Secured Within the openings, a cover to close the top and a plate to close the slot..

In an explosive engine of the opposed type,y 1he combination with the cylinders and operating parts, of a` crank case integrally 'formed in one piece having openings in its ends to which the cylindere` are Secured and having an opening in each side and a Slot, leading to one of said openings and bearings in said openings. i

In testimony whereof I aflix tn v signature in presence of two Witnesses.
