ATTORNEY CHARLES STEELY, OF PHILADELPHIA, PENNSYLVANIA:

EXPLOSIVE-ENGINE Specification of Letters Patent.

" Patented Feb. 16, 1909.

. Application filed June 16, 1908. Serial No. 438,744.

To all it may concern:

Be .it known that I, CHARLES M. STEELY, a

citizenof .the United States, residing 'at Philadelphia, county of Philadelphia, and

I State of Pennsylvania, have invented a certain new and useful Improvement in Explosive-Engines, of which the following is a specification.

My invention relates to a new and useful improvement 1n explosive erg'ines, and has for its object to provide an exceedin ly simple anllefi'ective device of this character whereby an explosion maytake place upon either side of the piston thus providin a double action eiiplosive engine; a furt er object of ny invention is to provide an en gine of this character which Wlll be cooled by the, airivhich is to be used with the gasolene or other fuel to provide a charge for the escape of the gas. bottom G of the cylinder acts as an intake 3 en ine. I p

\ 1th these ends in view, this invention consists in the details of construction andv combination of elements hereinafter set forth and then specifically designated by the thereof.

In carrying out my invention as here embodied, A represents the cylinder having the passagesB formed between the outer and inner walls C and D respectively thereof, and E thebase having the brackets F formed on the outside thereof for securing the enginein position upon a suitable frame.

G represents the bottom of the cylinder which is formed therewith, and formed with this bottom is the bearing H in which are placed the packing rings'I adapted to bear against the piston rod. J' to prevent the The hole K formed in the for-the charge and the edges thereof form a seat for the valve L, the stem M of which slides up and down in'the arch N which holdsit in position relativ to the hole K. i

The piston rod J is forraec from a hollow tube having a thread a cut on its upper end on which is threaded the piston O, the bottom and side of said piston being cast in one piece and on the inside surface of the upper portion of these sides is formed a thread I).-

c indicates nuts threaded upon the piston rod upon either side of the bottom of the piston so that they may be run against-the bottom thus holding the piston permanently in'place. The top d is threaded on the piston and has an arch P formed therewith in which the valve stem Q of the valve R is adapted to slide, said valve R closing the )assage way of the piston rod when it is forced down against the. same by the spring S. T indicates a guard which is also formed on the top of the piston so that when the piston passes the outlet or exhaust it will prevent the charge which is being taken in from also passing out said exhaust. The cylinder head U is secured to the top of the cylinder by suitable bolts U so that it may be readily taken oil if it should be so desired.

Secured to the lower end of the piston rod J is the cross-head V which is tight fitting and adapted to slide up and down within the base. and has a bracket lV formed on the lower side thereof. and to this bracket is so cured one end of the connecting rod X, the other end of which is attached to the crank shaft Y, and this is fastened to the shaft Z on which is secured the fly wheel Z.

A indicates an air inlet pipe through which the air passes into the passages 13 around the cylinder, cooling the same as it does so, into the pipe B which has the two inlets-C and I) then through the pipe E to the carbureler l!" which may be of any desired style where it is mixed with the gasolene entering the same from the guso cnc supply pipe (l', this mixture or charge leaving the carburetor passes into the pipes H and l, the pipe ll leading to the chamber between the bottom of the cylinder G and the cross-head V, the other pipe I leading into the base E. The charge which enters the chamber formed between the bottom of the cylinder and the cross-head at thepropcr time enters the lower portion of the cylinder through the hole K. the charge entering the base passing up through the piston rod J at l the proper time into the upper portion of the cylinder as will be hereinafter do-wribcd.

The exhaust indicated by the reference i lctteixd is situated in a central posiliouor contact. bolts N to which is secured the wire 0.

. P indicates a contact spring which as the commutator revolves with the shaft will come in contact with the contact bolts N thus forming a connection allowing the current of electricity to pass to the spark plugs.

In order that the commutator may be turned so as to advance the spark I secure to said commutator a rod Q, and to this rod I fasten a lever B which is attached to the engine so that it may be readily moved in the desired direction.

In practice the air is taken in through the pipe A when it then passes around the cylinder between the inner and outer walls then into'the pipe B through the inlets C and D then into the pipe E from where it passes tothe carbureter h" at which point it is mixed with gasolene entering through the supply pipe G from this point it passes as a mixture through the pipe H into the chamber formed between the bottom (l of the cylinder and the cross-head Y. ()n the upward stroke of the piston this charge is drawn into the lower portion of the cylinder through the opening K by suction, as the piston descends it compresses the charge into the lower portion of the cylinder the valve L preventing the escape of the charge and at the same time the charge which left the carbureter and entered the base through the pipe I is drawn upward through the hollow piston rod J into the upper portion of the cylinder. When the piston is at the length of its downward stroke the charge in the lower portion of the cylinder is exploded which drives the piston upward conipressing thecharge in the upper portion of the cyhnderdischarging the burned gases through the exhaust J and drawing a new charge through the opening K to the lower part of the cylinder, and when this piston has reached its upward strokethe charge in the upper partof the cylinder is exploded which drives the piston down again discharging the burned charge through the exhaust J and takes'ina new charge through the hollow pistonrod J, the guard T preventing this charge from passingput of the exhaust. This up and down movement continues as long as the proper charge entersv the cylinder and is exploded, and this movement will cause the crank shaft Y to turn through the medium of the connecting rod X which will cause the shaft Z to rotate.

Of course I do not wish to be limited to the exact details here shown as these may be varied without departing from the spirit of myinvention.

Having thus fully described my invention, what I claim as new and useful, is-
