T0055 whom it may concern:

Be it known that I, FsEn'sRroK RICHARD SIMMS, a subject of the Queenof Great Britain, residing at Loadon, England, have in plosion Engines orldoiors of which the following is a specification. I

This inventionfrelates to explosion-engines;

iergd'escribed, reference being had tothe. ao-

form in which I have contemplatedemb'odying my invention, andsaid iiiventio i is fully disclosedin the following description and claim. Referring to the said drawing, the figure is asectionalelevation of an explosion engine or motor cmbodying'my invention and having a fan for cooling the cylinder and the exhaust-passage thereof. The cylinder may be pr vided'with ribs of a suitable heat-conducting material, such ascopper, the said ribs being preferably arranged longitudinally upon the cylinder, and in some cases in combination with the ribs 1 provide a water-jacket'aroiind the cylinder, or means for spraying water into the air-curfan can hef'employed. Thewater-spray can he used inconsired. fin combination withthefan i also arrange a dynamo-for igniting the explosive mixture for driving the engine, the said dynamo preferably having its armature mount-- ed upon the zrotatingifan-spindle and its field magneisseeured to a fixed part of. theengi'ne, althongh if desired, the reverse arrangement can be made use of.

;.v 5 f f.

In the accompanying drawings, Figure 1 is or motor having a fan for cooling the cylinder and the exhaustpassage thereof. Fig. 2is a similar view of an explosion-enginehaving a fan foroooling and regulating the same, the cylinder being shown provided with longitudinal ribs. lfig. 3 is a sectional elevation of an explosion-engine having a fan for cooling. the cylinder thereof, which is'p'rovided with Fig. i is a view similar to Fig. 2 of an explosionenginc having a fan for cooling the cylinder v thereof and means for spraying water onto; the cylinder'or fan. Fig. 5 is aseotionalele' vation 01? an explosiomengine havingawfan Serial No. 661,684. (No model.)

in connection with the fan for i gnitinggthe explosive charge.

A is the explosion engine or motor, a the cylinder, and hitiie exhaust thereof.

c is an ont'ei sheet-metal jacket or casing inolosing the cylinder a and exhaust b, the said'jacket or casing having for its object to direct the cooling-current of air, as hereinafter described.

dis the fan, the said fan being mounted upon a spindle e arranged at theouter end '65 of the cylinder a, the said fan being rotated from the crank-shaft f of the engine by means of a belt or cord g, which. passes over pulleys hand 2' upon the spindle e and crank-shaft f, respectively. K

j is'one of a pair of guidepullcysfor the .belt '9, the said pulleys being carried in bracket 1;, fixed to the jacket 0.

Z is a jacket arrangedaround the exhaustpassage 6, the said jacket beingformedflaring at its upper end and having for its object to ca'dse a current of air to flow along and in contact-with the said ekhaust-pa'ssage. v

With this construction when-the engine is running-the fan, "which is keyediupon the spindleais rotated and drives a current of air in the direction of the arrows (indicated in v Fig, 1) inside the jacket c and into contact with thewallsof the cylinder a of the engine, so as to efficiently cool it, the flaring jacketl also directing air against the wallsof the. ex-

haust-passage h, as above mentioned;

Having now particularly described'and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- In an explosive engine, the combination with theoylihcler provided with an exhaustp0rt,-of acylindrical main casing surrounding the cylinder and exhaust, a,i'0tary fan mounted on the cylinder and adjacent to one end of said casing, a casing surrounding the exhaust, and having its axis disposed parallel to the axis of the main casing, and provided at theend adjacent to the fan, with-a flaring collar, whereby the air from the fan will be deflected inwardly around the exhau substantially as descri bed,

FREDERICK RICHARD SIMMS.
