Specification of Letters Patent. Patented Sept. 20, 1910.

Application filed January 15, 1910. Serial No. 588,239.

Be it known that I, JAMES I. Wooo, a citizen of the United States, residin at Salida, in the county of Chalfee and tate of. Colorado, have invented certain new and useful Improvements. in Explosive-Engines, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to improvements in explosive engines and its objects are to proean improved means for su plying a sufiicien't quantity of air to the cy mder, 1mproved means for facilitating the exhaust of the burned gases, an improved means for supplying the oil and igniting the charge.

With the above and 0t er ob ects in view, the invention consists of the novel construction, combination and arrangement of arts, hereinafter fullydescribed and claimed: and illustrated in the accompanying drawings in which;

Figures 1 and 2 are side and top views of an fexplosi ve engine embodying my improvements; Fig. 3 1s a vertical longitudinal section through the cylinder and other parts of the engine; Fig. 4 is a vertical transverse section taken on the plane indicated by the line l-4 in Fig. 3; Fig. 5 is an end view of the cylinder with one of its heads removed;

Fig.6 is an'inner end view of the other head of the cylinder; Fig. 7 is a detail sectional view taken on the lane indicated by the line 7 --7 in Fig. 3; the piston. Y

Referring ore particularly to the drawings 1 denotes the cylinder of my improved engine and-2 and 3 denote the heads of the same. .The body 1 of the c' linder is preferably of cylinder shape an surrounded by a water cooling jacket 1 having upper and in the intermediate lower inlet and outlet connections 5, 6. Instead of providing a single port or opening portion of the cylinder 1 for the inlet of air I em 10 a substantially annular series of re 1al y extending openings 7, the outer portions of which comv inder 1 and they are closed by the head 2,

municate with lon itudinal assages 8 formed in the wane the cylin er and extending from the ports 7 to similar radial passa es 9 which communicate with the rear end 0 the plylinder. The ortsor' assages 9 are forme by grooving the end 0 the cylig. 8 is a detail view of adjacent its rear end and air is adapted to be drawn by the piston through this opening 13 and'to be then forced through the ports or 'assages 9, 8, 7, into the explosive end of t e cy inder in advance of the piston, as presently explained. The exhaust passes out of the cylinder through two openin 14 arranged so that they converge in a sing e outlet ort or o ening 15 formed in a boss at the Bottom 0 the cylinder about midway the length of the latter. To deflect the exhaust gases toward the openings 14 and defleet the air coming into the cylinder throughthe ports 7 the its end formed with a ro ecting deflecting rib 16, as shown in the rawing.

On the outer end of the piston rod 11 is arranged a trunnion-carrying head 17, the trunmons of which are pivoted in the arms,

suitable hearings on the bed and has at its ends the usual fly wheels 22.

The head 3 of the cylinder is bolted or otherwise secured to the latter and consists of a circular plate, from the center of the outer face of which rojects a. cylindrical enlargement 23 wh-ic contains a' central bore or passage 24, an outer circular chamber 25, and an inner annular chamber 26. The chamber 26 communicates with the cylinder 1, and in connection withthe bore or passage 24 forms a tubular projection 27 against which oil is fed throu h a radial passage 28 formed in the circu ar part or plate of the head 3. The outer annular r the outer endiston may have chamber 25 is closed with the exception of its communication with the bore 2 and it is separated from the inner chamber 26 by a radial wall or shown in the drawing. Oil is supplied to the inlet 28 from a force ump 30 arranged on one side of the cylin er and having a discharge pipe or connection 31 communipartition 29, as clearly eating with the passage or inlet 28 and an intake pipe or connection 32 leading from a suitable oil tank or other source of supply. The piston of the pump 30 is con- .nected" to a slidable rod 33 which is actuated in one direction by a surroundingcoil spring 34 and has at its free end a roller 35 tobear against an eccentrically arranged annular member or cam 36 mounted for transverse sliding movement on the engine shaft '21 and held normally in eccentric position by means of a coil spring arranged on one of the guide pins which guide the cccentric-36 in its radial move- ."through the plurality of radial ports or passages 7, at the same time the exhaust gases passed through the converging outlet ports 14, which latter tend to muflie the exhaust and reduce noise. 011 the forward stroke .of the piston the charge is compressed in advance of the latter and the heat in the boss or member-23 on the head 3 causes the charge to be ignited. In starting the engine the member 23 must be first heated to vaporize the oil which drops upon the tubular projection 27 in the chamber 26, but after the engine has been started these parts will be reheated at each explosion because the explosion will force the flame into the bore 24 and chamber 25 to thoroughly heat .the parts of the member 23. It will be further understood that when the engine "is in operation the oil dropping upon the heated tube 27 will quickly vaporize and mingle with the charge of air.

\Vhile the preferred embodiment of the invention has been shown and described in detail, it will be understood that I do not wish to be limited to the precise construction set forth, since various changes in'the form, roportion and arrangement of parts, and 1n the details of construction, may be resorted. to within the spirit and scope of the invention.

Having thus described the invention, what is claimed is: 4

1. In an explosive engine, the combination of a cylinder formed with a transverse row, of inlet ports intermediate its ends, a corresponding series of radial ports, at one of its ends, and a series of longitudinal passages connecting the-said parts, the cylindenbeing also formed. with an air inlet' port arranged adjacent the last mentioned end ofthc cylinder, and an exhaust portarranged adjacent the first mentioned series of inlet ports, a piston to reciprocate in the cylinder, a head upon one end of the cylinder and provided with an outwardly pro-' jecting boss containing a central bore and inner and outer chambers communicating with the bore, the inner chamber also 'communicating with the cylinder and forming with the bore a tubular portion, said head being also formed with a radial oil inlet passage to discharge oil upon said tubular portion, and a pump actuated by the engine and adapted to forceoil through said oil passage.

, 2.In an explosive engine, the combinationof a cylinder. a head at one end thereof 7 and provided with an outwardly extending enlargement containing a longitudinal bore and inner and outer chambers communicating with said bore, the inner chamber also communicating with the cylinder and forming in connection with the bore a tubular portion, means for supplying oil to said tubular portion, and a piston to work in said cylinder. p

3. In an explosive engine, the combina"- tion of a cylinder, a member containing a longitudinal bore and inner and outer chambers communicating with the bore, the inner chamber also communicating with the cylinder and. forming in connection with the bore a tubular portion, and means for supplying oil to said tubular portion.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses. A JAMES I. WVOOD. Witnesses:

FRANK EATON, M. A. BROMLEY.
