having ports for intake and exhaust and operating ported sleeve valve means associated therewith.

For a more detailed understanding of my invention, reference may be had, to the accompanying 'drawing which illustrates one embodiment of my invention, and in which:

Fig. 1 is a vertical sectional view of an engine cylinder constructed in accordance with my invention,

Fig. 2 is a sectional view through the cylinder ports taken substantially on the line 22 of Fig. 1,

Fig. 3 is an elevational view as viewed from the left of P18. 2,

Fig. 4 is a fragmentary vertical sectional view of a modifledconstruction, and

Fig. 5 is a sectional view taken on the line 5- of Fig. 4.

In the accompanying drawing I have illustrated an engine of the sleeve valve type and for purposes of illustration I have chosen to show my invention incorporated with'a single sleeve valve engine of the Burt-McCollum type in which the sleeve valve is given a combined reciprocating and oscillating movement with respect to the sleeve and cylinder axes wherein any point on the sleeve traverses a closed path.

The present embodiment of my invention in;

eludes an engine crankcase "to which a cylinder structure A may be secured in any suitable manner. The cylinder structure A isprovided with a central bore ll forming a cylinder for receiving the sleeve valve means I 2, a piston l3 operating within the sleeve valve and adapted for connection with an engine crankshaft (not shown) by a connecting rod I I. A cylinder head It is secured to the cylinder structure by bolts It or other suitable fastening devices and is provided with a reentrant portion l'l depending within the cylinder in spaced relation therewith to provide a sleeve pocket IQ for accommodating the outer 1931, Serial No. 507,661

and below the cylinder ports and that portion of the cylinder structure in the region of the ports is provided with a circumferential groove 24 having a width exceeding the height of the ports as clearly illustrated in Fig. 1. This groove preferably extends substantially around the cylinder and the said ports opening into this groove are thus exposed to the outside of the cylinder thus permitting the external machining of the ports. As shown in Fig. 2 it will be observed that I have provided a plurality of intake ports I! and a plu- In the manufacture and assembly of the engine, the cylinder fins and the groove are preferably, machined, then the ports may be mechined if so desired, after which the gas conducting manifold portions may be secured in place, said'portions cooperating with the ports and covering or enclosing same.

Preferably, I have provided .an intake mam-- fold structure 25 and an exhaust manifold strucrality of exhaust ports 20. i

ture 26, the intake manifold structure provided with an inlet portion 21 and an arcuate fuel mixture distributing chamber 28 communicatin with all of said intake ports l9, and the exhaust manifold structure is provided with an outlet portion 29 and a gas chamber 30 communicating with the exhaust ports 20. Preferably these intake and exhaust manifold structures substantially encircle the cylinder to enclose the ports (see Fig. 2) and are secured together and clamped to the cylinder by the bolts ll. These manifold structures are constructed to be secured within the groove 24 carried by the cylinder.

Furthermore, these intake and exhaust manifold structures are constructed reversible and thus either of them may be ,so assembled and secured to the cylinder asto direct the inlet and outlet portions respectively of the intake and exhaust manifold portions forwardly or rearwardly of the engine with respect to the slip stream as indicated by the arrow (see Fig. 2). The herein illustrated cylinder structure may be integrally cast of aluminum or other material preferably having the characteristics of aluminum, and the manifold structures, which are secured thereto and coopfiige with the ports to enclose or cover same ma constructed of steel or an'aluminum alley or other suitable material.

'.In Figs. Land 5 I have illustrated av sleeve valve engine of the radial liquid cooled type in which the cylinder structure 40 is provided with jacket portions II and 12 respectively located above and below the ports 43, said insert such as the gas conducting structure 44 which cooperates with the ports 43 to enclose or cover same bein provided with jacket portions 4! connecting the cylinder jacket portions ll and I2.

It will be apparent to those skilled in the art to which my invention pertains that various modifications and changes maybe made therein without departing from the spirit of my invention or from the scope of the appended claims.
