Specification of Letters Patent. Patented Dippy 3Q, 1911;

Application filed. September 7, 1909. Serial No. 518,445.

I of reference markedthereon, which form a partoi this-a plication.

. This invention relates to improvements in explosive engines and particularly to that type known as rotary engine, the'object of the invention being to'produce a'rotary gas engine which will have an efiectual explosive resistance wall spaced from the driving piston whereby such driving iston will receive the full force and efi'ect oi the explosion.

A further object of the invention isto produce'a rotary engine which will have a plurality of ex losions to each revolution.

A further 0 ject of the invention is to produce a sim la and inexpensive en ine andyet one which will be exceedingly e cot ve for the purposes for which 1t is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claim.

In the drawings similar characters of reference indicate corresponding parts in the several views.

Figure 1 is a side elevation of the complete engine. Fig.- 2 is a sectional view taken on a line ww of Fig. 1. Fig. 3 is a sectional view showing the compression and explosion chambers and a portlon of the drive chamber. Fig. 4 is a sectional view taken relatively on a line y-y of Fig. 3.

Referring now more particularly to the characters of reference on the drawings 1 designates the base frame of the en inc, the

same having projectin journal names 2 in which is journaled t e main drive shaft 3. On said shaft 3 is mounted the drive wheel' having a flange 5 rojecting from its outer rim into a. roove t? in a drive cylinder casin forme of two members 7 and 8 suitably anged and bolted together as at 9.

Within said drive cylinder are two piston heads 10 secured to the wheel 4: by means of; a dovetail 11 or other suitable means, such' piston heads having packing rings 12.

13 is a cylinder divided into a compression chamber l and an'explosion chamber 15, such division being accomplished by an angular division Wall 16 providing a horizontal slielf 17 in which is a valve 18 having a rod 19 projecting outside the cylinder 13 and having acollar 20, there being a spring 21 interposed between said collar and said cylinder 13.

In the chamber 141 is a piston 22 having a rod 23 connected with a guide 24 connected.

by a counter shaft 25' with a. crank 26 driven .by a gear 27 mounted on ashaft 27 connected by a chain28 with a gear 29 mounted on a shaft 30 journaled on the casing 7 there being another gear 31 on said shaft 30 connected by a chain 32 with a gear 33' on the shaft 3 all the gears 27, 29 and 31 being and forces said compressed mixture into the explosion chamber 13 and just at-this time the rcvolution'of the wheel 4 brings cams 35 on said wheel into contact with rollers 36 and arms 37 of a cross head 38 carrying a sliding plate valve 39 over the end of the explosion-chamber 15 and completely closing said chamber while one of the piston heads 10 passes the line of said valve 39, this being occasioned by a portion a of the cams 35 following the contour of the cylinder 78 for the length of said piston head 10 and when said piston head lO'has just passed the line of the valve 39 the cam 35 abruptly terminates and the rollers 36 drop ofi permittin a spring 40. interposed between the cross ead 38 and a guide lug'l on the valve back or seat 42 and surrounding a rod 43 movable through said lug tl, to return said'valve 39 to normal position across closing said cylinder to the rear of the head 10 whlch has just passed and communicating with a port 45 in the chamber 15 with a port 46 in the valve 39' thus opening the chamber 15 into the cylinder 78 and then the explosion takes place in the chamber 15 and passes into the cylinder 7--8, the valve 39 giving the necessary resistance between it and the head 10 and thus .the explosion drives the head 10 and incidentally the drive Wheel taround the cylinder 7-8, the exhaust taking place near the bottom of said cylinder as at 47, the above operation taking lace continuall for each of the piston heads 10 since, as escribed, there are two compressions and explosions for each revolution of the wheel 4.

The valve port 46 may have a suitable packing ring 48 and likewise all the other ports and arts may be suitably packed to prevent lea age but this of course would be of the ordinary type of packing, hence, I

make, no mention of the same at thistime.

gas engine which substantially fulfils the objects of the invent-ion as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device still-in practice such deviations from such detail may be resorted to as do not form a departure from-the spirit of the .open communication between sai explosion cylinder and said workingchamber, arms on said valve, a revolving wheel, cams on said Wheel engagin said arms, said cams havin a portion fol owing the contour of said wheel, as described. v y

In testimony whereof I aflix my signature in presence of two Witnesses,
