To all whom, it rim/y concern.-

lie it known that I, HERMANN EDGAR EBBS, a subject of the King of Great Britain, residing at Nuremberg, Bavaria, Germany, have invented an Improvementin Gas-Engine Cylinders, of which the following is a specificalion.

In the form of gasengine in which the exhaust-gases escape through notches, slots, or the like formed in the cylinder-wall, as is the case, for instance, in the two-stroke engines of Clerk, Oechelhauser, and Kin-ting, the drawback has been found that as a rule the uncooled webs or bars which lie between the said slots and around or between which the hot exhaust-gases of the engine pass easily crack by reason of the great heating produced by these waste gases. As, further, these bars are exposed to great strains, owing to the tractile force arising in the engine, they make the working of the gas-engine insecure and render a replacement of the entire cylinder necessary whenever such cracks arise.

Now the present invention has for its ob- 2 ject to avoid too great a heating of the bars by animproved arrangement, on the onehand, and, on the other hand, to render unnecessary the renewal of the entire cylinder in case cracks should develop. For this object the 50 part of the cylinder containing the notches or slots is formed of a separate inserted piece which contains the annular exhaust-passage and is provided with cooling-chambers traversed by water in such a way that each bar 1y- 5 ing between two adjacent apertures is cooled separately, and therefore a great heating of the bars by the waste gases of the engine can no longer take place. If, however, this annular piece should be damaged, it can be changed or replaced without rendering necessary the renewal of the entire cylinder.

This'iniproved gas-engine cylinder is shown in the accompanying drawings.

Figure l is a longitudinal sectional View on lines B B of Fig. 2, and Fig. 2 is a transverse sectional View on line A A of Fig. 1.

A separate annular intermediate piece 0 is arranged between the two parts a and I) of the cylinder, the internal diameter of the part c exactly corresponding to that of the bore of the cylinder. The said intermediate piece contains the annular exhaust passage d, which is connected with the interior of the cylinder by radial slots 6, distributed uniformly over the entire periphery, and from which the waste gases of the engine are con- Yeyed away through the pipe-socket f.

The wall of the intermediate piece 0 is traversed on all sides by cooling passages through which water flows, which passages consist of an annular space g in the outer wall of the intermediate piece and passages i, lying in the inner wallthat is to say, traversing the bars 7L in an axial directionand annular side passages k, connecting the passages g and 'L' with one another. The water admitted at a suitable point into this cooling-chamber flows around the radial slots 6, through which the hot gases escape from the cylinder, so that a strong heating of the bars situated between the slots can no longer take place. Should the intermediate piece become damaged, it may be taken out and repaired or replaced by a fresh one by loosening the screws Z,which hold the intermediate piece to the flanges m of the parts a and Z) of the cylinder, and pushing the latter apart.

I declare that what I claim is- A removable insertion for engine-cylinders havingexhaust-slotsforcarryingofifthewaste 8o gases, comprising an outer casing, coolingpassages in said casing, an annular exhaustpassage, slots through the inner wall of said insertion communicating with the interior of the cylinder and the annular exhaust-passage, a discharge-socket for the exhaust-gases communicatingwith the annular exhaust-passage, and cooling-passages in the outer wall of the insertion, in the bars between the inner exhaust-slots, and extending radially be- 0 tween said inner and outer cooling-passages, substantially as and for the objects set forth. In witness whereof I have hereunto set my hand in presence of two witnesses.
