To all 'whom t may concern.'

Be it known that I, ALBERT BIE, a subject of the Kingdom of Norway, residing in Winterthur, Canton of Zurich, Switzerland, have invented certain new and useful Improvements in Engine Construction, of which the following is a full, tr'ue and complete specification.

Ihe invention relates to internal combustion engine construction embodying improvement in the assemblage and manufacture of the combustion cylinder and special facilities for cooling the same and accommodating the thermal expansions and contractions, as will hereinafter be made apparent to those skilled in the art.

In the accompanying drawings:

Figure 1 is a vertical section through the head end of a cylinder containing the improvement in one of its forms;

Fig. 2, a plan thereof;

Fig. 3, a fragmentary vertical section of another form;

Fig. f1, a horizontal section on the line IV-IV of Fig. 3;and

Fig. 5 is a View of the engine, partly in elevation and partly in vertical section.

The water-jacket 1 is provided at its head end with four lateral lugs 13, which vare clamped to the upper ends of tie rods or columns `2 rising from the base 14, and its lower end is provided with similar guide lugs 15 also engaged to the rods and capable of movement thereon to accommodate lengthwise expansion of the water-jacket wall. The water jacket cylinder is thus relieved of longitudinal stresses and its head bearing the valve organs is held in fixed position with relation to the crank shaft 36 under all conditions.

The upper portion of the water-jacket which is swelled outward, as shown at 16 is formed with a depending, reversely-turned inner wall 17, forming the circular boundary of a head-receiving recess, and the lower end of this wall, being appropriately bra-ced as indicated, forms an annular seat 8 to receive an outwardly directed head flange 19 on the upper end of the cylinder liner 6. The latter is a separately made part intended to complete the water jacket and surround the 'combustion space and the reciprocating piston 20. At its lower end the liner 6 is :fitted to the water jacket in any suitable manner, which will retain the cooling water and accommodate such difference of expansion as may occur.

The head 3 is hollow for circulation of water, entering at 3a and leaving at 3b, and 1s intended to carry the usual valve organs, as indicated by the valve sockets 4. This head is set into the upper yend of the water- ]acket, bearing against the top of the head flange of the liner, with which it forms a tight seal'against leakage from the combustion space, by means of interengaging facings 7, with or without a gasket. The top of the head is formed with an outwardly extending liange 21 overlying the top of the water-jacket, to which it is fastened by bolts 5. These bolts press the'head and the liner fiange together and against the seat 8, and,

permit the ready removal of the head without disturbing the columns 2 or disconnecting therefrom the cylinder part l. The liner 6 can also be readily withdrawn if desired when the head has been removed.

The liner flange 19 is preferably recessed, as indicated at 9, in order that it may be cooled by access of the coolin water to its interior, and the recessing of t e flange may be in the form of a continuous annular groove recess, as shown in Fig. 4, or of separate cavities,l as suggested in Fig. 1; and in either event the interior of the flange may be placed in communication with the waterjacket space by openings 10 through the wall 17, above the seat 8. Furthermore, as shown in Figs. 3 and 4, openings 12 may pierce the under side of thehead flange, opening into the Water jacket space below the seat. In this construction the up eriportion of the water jacket space is pre erably divided off, either partially or entirely, by a wall 22 connecting the lower edge of the wall 17 with the outer wall of the water-jacket, thus facilitating the circulation of water from one part of the water-jacket space to another and through the interior of the flange 19. The lip 11 in Fig. 3 obstructs escape of water through the crevice between the head and water jacket.

From the foregoing description it wllbe apparent that the principle of the invention is not confined to the specific construction above described, and that various modifications, changes in proportion and alterations may be made therein without departing from the scope of the followingfclaims.

I claim:

l.' An internal combustion engine comprleing a base, a set of tierods rising therefrom, a combustion cylinder having a water-jacket between said rods and detachably secured to the latter by its upper end, and a cylinder head fastened to the cylinder independently fthe tie rods and removable without disturbing the connection of the cylinder thereto. 4

2. An internal combustion engine comprising a base, a set of tie rods rising therefrom7 a combustion cylinder having a water-jacket between said rods and detachably secured to the latter, a cylinder head having a cylindrical hollow body set within the upper end of the cylinder and a downwardly facing shoulder at its top, and bolts assing through said shoulder into the cylin er end and permitting the removal of the cylinder head without disturbing the connection of the cylinder with the tie rods.

3. In an internal combustion engine, the combination of a base, a set of tie rods rising therefrom, a water-jacket between and detachably secured by its upper end to said tie rods, a separate cylinder liner terminating at its upper end below the top of the water-jacket, a cylinder head comprising a cylindrical hollow body set into the upper end of the water-jacket against the end of the cylinder liner, and bolts holding the cylinder head in place and permitting removal of the same outwardly through the top of the water-jacket.

4. In an internal combustion engine, a water-jacketed cylinder detachably connected by its upperl end through tie rods with a base plate and having its head portion constituted of outer and inner parts, the outer of said parts being integral with the waterjacket and the inner part being fastened independently of the tie rods and removable outwardly from the top of the cylinder.

5. In an internal combustion engine, the combination of a base, a set of tie rods rising therefrom, a water-jacket between and secured by its upper end to said rods, said Water-jacket having a seat below its upper end, a cylinder liner having a ange resting on said seat, a cylinder head comprising a cylindrical hollow body set into the upper end of the water-jacket and bearing against the end of the cylinder liner, and means separate from the tie rods for pressing the cylinder liead and liner against said seat.

6. In an internal combustion engine, a water-jacket having an inner wall at its head end forming an inner boundary of the waterjacket space, and a seat on said wall in wardly of the end, a cylinder liner having a flange against said seat, a cylinder head comprising a cylindrical hollow body set into `head end, a liner having a flange bearing against said seat, a head comprising a cylindrical hollow body set into the water-jacket and bearing against the liner flange, and means engaging the head for pressing the same and the liner flange t0 the seat, said head and liner being free for radial expansion in theI water-jacket.

8. In an internal combustion engine, a water-jacket having a seat inwardly of its head end, a liner having a iange bearing against said seat, and lateral passages in the wall of the water jacket affording access for the cooling water to said liner flange.
