T o all whom 'it may concern:

Beit known that .l CHARLES BUnGnss, Jr..

a citizen of the United States, residing :it

W'euona, in the county of l-Iershall and State "of Illinois, have invented certain new and useful Improvements in Gas Engines, of which the followingr is a specification.

The invention has reference to iinprove' ments in gas engines of the well known fourcycle construction, the principal object being .to provide an interna combustion engine comprising a cylinder and a piston therein of the double acting or reciprocating. type in which the gases are exploded at opposite ends of the piston, the pistou being hollow and having a port communicating with an opening through the cylinder wall and the pistonl rod working free within a housing or tube which' forms a communicating passage he# tween the crank chamber of the engine and theA pistonwlierchy a continuous'cireuit of a cooling medium, such as air, may be' assed from the crank chamber around the lengt-h of the piston-rod and within and around the 'piston and then discharged through the'cylinder wall, thereby preventing the overheating of the housing or tube, pistonend piston-rod, which overheating ol"A any of said parts frequently renders gas en# gines of this type inoperative.

ln the accompanying drawings, Figure 1 is a vertical section of a single-cylinder engine embodying my improvements. Fig. 2 is a vertical section designed to show an airpuinp in combination with an engine. F 3 is a. cross-section of a cylinder on the line 3--3 of Fig. 1, with parts removed. Fig. 4 is an enlarged detailed section of the piston, 'piston-guide and gland with parts hrokcn away and other parts in section.

Referring now more particularly to the drawings, 5 represents as a whole the cylinder havdng the'usual outer casing G forming a water-jacket- 7 and a crank ense S. Between the crank case 8 and the cylinder 5 is secured a guidecyli1nlerv 9 which is bolted to the crank case by means of bolts 10 and its uper end engaging a circumferential boss 11 orincd on the outer casing 6. At each end of the cylinder 5 is an explosion charnhcr 12 and 13 with the usual intake valves 14, 15, exhaust valves 16, 1 7, caps 1S carrying the spark plugs 19 that. are secured tothe intake side of the engine and the caps 20 carrying the pet-cocks 21 on the exhaust side of the engine. The ducts 22 lead to the intake valves `for admitting the gaseous lmixture thereto and the duc ts 23 carry away the discharged gases, while 24 is the discharge port for theliquid in the watenjacket.

Within the cylinder is a double-headedpiss ton 25 carrying the usual piston rings 26 at both ends thereo,thc piston being hollow, except for the. strengthening rods 27 each meeting at a point substantially 'central' within the interior thereof to form an attaching pointv 2Q for the. piston-rod 29. The pisto'n-rod is adapted to he secured to the said attaching point by ineens of threads and to he secured more firmly b v` thebolt 30. Said piston-rod extends through one end of Said:

piston which is provided wit-h an annular opening having an annular threaded boss 31- surrounding seid opening and u sliding tube 32 or conductor for a coodin? medium that is threaded :it one end :annifs adapted to engage;

outer casing 6, the usual pacln'n rings 34 being provided. It is to e un erstood that the tube 32 is hollow, one end opening into the piston and its other end into' the crank case. The piston is cored as shown at 35 and a `series of ports 36 in the piston permit ail: coming through the tube 3.. to css out into the chamber 3T that is formed y the cylinder wall :ind the cored portion oi the piston.' The 4cylinder' wsdl is provided' .with-'mie or more exhaust portions 3S whereby when the' piston is moved to bring any1 part' of the cored portion thereof-opposite the said ports,

-the nir within the chsrnber Will pass; outV through said ports A3S.

Sliding uit-hin the gende-cylinder is a crosshead 39 to which one end of the piston-rod is secured, and the connecting rod 40 is secured. to .the crowhead by means of the wrist-pin The connecting rod is secured at its Y 41. outer .end tothe crank 42 towhich the'two- )artdrving shaft' 43 end 43 are secured. l`o the driving shaft 43* is attached a.` gear 44 that drives the gears 45 and 46 which Work I upon the stems 47 and 4S `of the exhaust and intake valve respectivelj', and the springs 49 are adapted to return said valves to theirf seats.

Referring to Fig. 2.. the gear 44 onshaft 43 j I drives the gear 46 which in turn is connected by Ineens of e shaft to an air-pump ande discharge pipe lconnected to said air-puni conducts the air therefrom into the cran chamber and guirlecylinder 52 re resent-s u. balance Wheel connected to the s mit 43.

operation air passes from the nir-pump into thecrank chamber and is forced from 'said crank chamber through the conductor or tube 32 into the piston and around the seme intov the chamber 37 until said piston in its reciprocating movement brings the cored y eb ' orce said air up through seid tube 32.

,i portion opposite the apertures or. openings 38 -.whereupon the en' passes out through the' cylinder Well, it being understood that 'by means ofi m eir-pump'there is a constant ressure ofl air Within-the crank chnmberitlo e object of forcing the air through the tube 32 is two-fold.k First, it cools the gland 33, whereby an enf/ine of the present constructionA is provid `'mit-h je. gland through which the piston-rod works that has twolrneens of' coolingA the seme, viz: the Water jacket sur- .a2-5 1 rounding seid gland end the --eir messing through seid tube. This gend 33 1s he por- -t-ion of the engine subgect to' the most friction and the moet nest. Secondly, the an" serves 'to cool the piston 1n th'ctrt basses mtonnd Y laround the seine, but tee prune-ry object of ftheinyention is to obteinnn e double'actih0'- a. crank and e. piston-rod1 e. conductor for a. v

'cooling medium surrounding said piston-rod,

means for maintaining a.. continuous supply of a cooln medium in said crank chamber, substantial y as described. 3. TheA combination with a double acting"- envine cylinder, formed `with one or more letere discharge ports for a ,coolin substantially cent-rally thereof, or 'e hollow piston in said cylinder havinga cored portion and lateral openings thereinto adapted to communicate with sind discharge ports of the cylinder, a, crank chamber, a. crank, and
