Be-it known that I, Linrorr T. Bsssn'r'r, a citizen of the United States, residing at Se.- lein, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in EXplosiveEngi'nes,of which the following is e specification.
. My invention relates to explosive'engines, and has for its leading objects the absolute scavenging of the cylinder; the avoidance of compression in the crank case and. elsewhere except n the working cylinder-whereby resistence to the pistonsis reduced; the main tenance of the cylinder-at comparatively low tern erat-ure by the large volume of air therein t e scavenging of thecylinder by means.
other than by co1npression; end the ettein me'nt ofthe above and other objects which will hereinafter be pointed out and claimed by meahs of asimple, ineirpensive, compact,
To the enumerated ends essentiellyiny in' vent-ion consists. in. toe novel construction and combination of parts hereinafter dedrawing's, wherein,
' Figure 1 is a. vertical central section, per
tiellyi'n side elevation, of an explosive eng ne of the two cycle type embodying my inven tion, certain parts being broken ewey. Fig. 2, a section of the same pertiellyin side'elevetion, taken-on line of Fig. 1 looking'in the directionbf the arrows, end'showing the air piston-at thebotiton-i of its stroke, and 3, 5

Inf the casing well, 15, ennulerly disposed eir edinissioi'r ports, 24, leading to the bottom of the chamber, 1 9. The upper portion oi'the crenkiceseis provided with o'gielui 25, to admit air and prevent compression; it will pump the busticn erd t' d with two "ets of openin? through the e. To
"e in. or otherwise to the un er fees of the y I, E A piston. the; *nber or these Hep structures isirnmeteriel; c The mechanism for operating the piston, 26, as follows: Upon the bottom of the crenl'g. case are bearings, 32. and 33,. for 'a, shaft, S l, upon which are two sleeves, '35
"respectively with segmental bevel geers, 37 and 38;end-,j upen their-outer ends respectively, with integral arms, 39 and 40. The
gear, 41, u on a stud, 42*, loosely mounted and 33. Fixed in lugs, 44 end 45, upon opposite sides the c'ev e, .36, are rods, lfi -end e7 resoectively. "These rods pass loosely-throng openings, 48. and. 29,- in
sides of yoke, 52, looseupon the crank or crank pie, 5, Piv'ote'd to the time, 10, by m, 5 is e fco'nnecting rod, 55, whose oppo siteendis pivoted by pin, 56,;to the lower end E:

disposed exhaust ports, 23, in the well, 16,
beunderstood;however, that the crank cese gear segments, 37 and 38, mesh with'e bevel in the cren case intermediate the bearings,
"lateral extensions, efl'fend 51, upon opposite tends from-the lower ports, 24, nearly to iis piston which rests bellows firm 28 hiredb P end provided upon their inner ends the crank reciprocates the yoke, 52, upon the rods, 4-6 and 47, thereby imparting a rocking motion to the sleeve, 36, .and its arm, 40.
. This rocking motion is imparted in an '0 posite'directionto the arm, 39, of the s eeve, 35, through the gears, 38, 41' andS'T.
Thus the piston rods, 57 and 63, are simul-' taneously raised and lowered by the rotation of the shaft, 4, and crank, 5, whereby the air piston, 26, is reciprocated in the chamber, 19; and the engine piston, 7, which acts as a valve to ports, 21, and inlets, 22, is reciprocated in the COIIlbUSlLlOIl.(fllliLIllbGl,
- 9r. .-Piston,'26,v performs its entire upward stroke while piston, 7, is opening'and closing ports, 22. 7 When piston, 7, in its descent, begins to open ports, 22 as shown in Fig. 2, the piston,
26, is at its lowest point, preparatory to its 'upward stroke. The piston, 7, however,-
still continues its descent one-eighth of a revolution of the crank to its lowest point, as shown in Fig. 1, at which time piston, 26, has performed two-thirds of its upward travel. Theremaining third of the upward travel of piston, 26, is performed during the next eighth of a revolution of the crank, 5. It will-be'seen that one-fourth.of the crank revolution is required for the upward stroke of the piston, 26, as shown in -I*igs'.2 and 3,
while three-fourths of a revolution is required forthe downward stroke of the'same.
It will be seen that exhaust ports, 21, by action of piston, 7 ,are opened s ortly before opening the' inlet ports, 22, thereby allowing.
the remaining pressure of the exploded charge to escape before the opening of the inlet ports, thus reducing the pressure in thechamber practically to that of the atmosphere before the opening of ports, 22, andthe upward travel of piston, 26'. Furthermore, by virtue of the large area of the ports, 21, 22 and 23, the resistance of the inclosed air to the upward travel of piston,
26, is reduced toa minimum. The entire upward movement of the piston, 26, is performed while the ports, 21, 22 and :23, are open, therefore there is no compression involved by either piston in scavenging the chamber, 9. This construction allows entrance into and passage through the chamber,
9, of a volume of air much in excess of the cubical contents of said chamber, and greatly in excess of the volume of air generally lntroduced into the combustion chamber. Not
. only does this produce practically perfect scavenging, but a large amount of heatdn the products of combustion 1S expelled in stead of passing through the cylinder wall.
Thus dispensing largely, if not wholly, with mechanical cooling. I v My structure is such as to prevent leakage of the exploded charge from the explosion 7 chamber around the orking piston into the crank case to pollute the charge in the crank case when orif the fuel is taken into the engine by way of the crankcase.
The described means for introducing the 7 air into the cylinder is not exclusive, as any auxiliary means of pumping or forcing the" air into the cylinder in a volume much in excess of the cubical contentsof the same is within the spirit ,of my invention. In 8 other respects my invention is not limited to the exac'tdetails' of construction herein shown and described, as va'riation's may be made therein without'violating the spirit of my invention. .Obviously -my invention 8 may be embodied in engines provided nith two or more cylinders.
