This invention relates to explosive engines the following is a specione of its objects being to provide a two.

and exhaust the gas.
explosion,
With the foregoingandother objects inv view which will appear as the4 description roceeds, the invention consists of certain I novel details of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims, it being understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing any of the advantages of the invention as set forth in the appended claims.
In the accompanying drawing-s the preferred form of the invention has been shown.
Tn said drawings Figure 1 is `la section through the engine and showing the vpositions of the pistons at the completion ofthe compression stroke or at the beginning of the power stroke. y Fig. 2 is a similar view showing the positions of the parts at the end of the power stroke. Fig. 3 is a similar view showing the-positions of the pistons` at the completion of the exhaust operation and at the beginning of the compression stroke.
Fig. 4 is a section on line the piston and its operating mechanism being shown in elevation. i Referring to the figures by characters of reference, -1 designates the cylinder of the engine having an inlet port 2 in one end and an exhaust port 3 in one side, the inlet port being provided with a suitable valve, not shown. A crank shaft 4 is mounted for notation in the crank case 5 and has va pitman 6 connecting it with an inner piston mounted for reciprocation and fits snugly within a .hollow outer piston 8 provided in the exhaust side thereof `Specification of Letters Patent.

with exhaust openings 9. The active end of the piston 8 is closed while the-other end thereof is connected by a toggle 10 with the base of the case 5. A link V411 connects the intermediate joint of the toggle with` the crank of the shaft 4 so that, during the rotation of the crank, the link will work the toggle back and forth and cause the piston 8 to reciprocate in properly timed relationwitli the piston 7 therein. The spark y plug 12 of the engine is preferably located ma recess 13 1n the cylinder at one side of the end of piston 8 when at the end of lits compression stroke.
lAssuming that the explosive charge isy compressed, it will be contained in the space between the-ends of the pistons 7 and 8 and between piston 8 and the head of the cylinder as shown in Fig. 1. As the recess 13 is` in communication with both of Athese spaces f the charge, when ignited, willl drive the inner piston 7 downwardly and cause the crank shaft to rotate as indicated by the arrow in Fig. 1. Link 11 will, during the first half of the rotation of the shaft, move theouter piston 8 slightly toward and then back away from the head of the cylinder and. at the same time, the inner piston 7 will move downwardly under the force of the explosion to the position shown in Fig. 2. During thethird quarter of the rotation of the shaft 4 the crank will thrust through the link 11 against the toggle and cause the outer piston 8 to move downwardly ,relative to the inner piston, bringing the ports or openings 9 into communication with the exhaust port 3 and causing the burned gases to be expelledfrom between the approaching piston heads. At the saine time a charge of fresh gas will be drawn into the cylinder by the descending piston 8, so that the engine will be recharged and the burned gases eX- hausted on the completion of the third quarter of the rotation, as shown in Fig. 3. The completion of the rotation ofthe shaft 4 will result in the simultaneous upward movement of the two pistons and the compression of the gas in the end of the cylinder until the parts reach the positions shown in Figs. 4 and 1 whereupon the operation described will be repeated.
