Application med February 21, 1927. Serial No. 169,741.
'This invention relates to internal combustion engines and refers more particularlyi to an improved cylinder head construction especiallyadapted, although not necessarily limited, to the sleeve valve type of engine.
located below cylinder cover D where it will l'not be acted upon by heat, which in many other instances, tends to vulcanize the joint ring and make removal thereof inconvenient. 17 is a joint ring supporting member which One ofthe objects of the invention resides; niaybaformedyvth afaoelS engagable with in providing an improved sealing means between 'the cylinder head and the'cylinder cover of an engine. A further object is to .0 provide a simply constructed cylinder head in combination with means for eectively sealing the joint, but which will not interfere with the circulation of the cooling liquid, ordinarily water.
` A further feature of the invention resides in the provision of a cylinder head water joint.y sealing means adapted to locate a siphon tubefor draining the cylinder headjof its cooling water. i
My invention also provides a cylinder head construction capable of being machined easily and at low cost.
Other features of my invention will be apparent from the following description with reference to the accompanying drawings in which I have illustrated specific embodiments of my invention, it being understood that modifications within the limits of my claims may be resorted to without departing from the spirit of my'inventionz With reference to the drawings in which like `characters indicate similar parts,
elevation, yof an engine cylinder showing my :5 improved cylinder head construction,
Fig. 2 is a plan View along 2 -2 o f Fig. 1, Fig. 3 is a detail perspective view of the joint ring supporting member, and
Fig. 4 is a view corresponding to Fig. 1, i0 illustrating a modified form of my invention.
In the drawings reference character A represents the cylinder, B the cylinder head, C the sleeve, and D the `cylinder cover, The cylinder head B may be. secured in place to l5 cylinder A by' suitable means such as .bolts 10, andl may further be provided with inner and outer walls -11 and 12 respectively, spaced to form a cooling jacket 13. VThe cylinder cover D may be securely clamped in place by any convenient means such as the nut .14
threaded to the upper portion of the cylinder head barrel 15. In order to provide a water tight joint I have provided a joint ring 16 of customary composition preferably ring 16 and having an edge 19 suitably sup;
ported as by' ribs 2O formed at convenient intervals on the cylinder head. Openings 21' permit free passage of cooling water between the acket 13 and the cylinder jacket 22. Conveniently located in an opening 21 is a Siphon tube 23 whereby, upon draining the water from the cylinder jacket, the water in the cylinder head jacket will also be removed.
The member 17 is preferably made of sheet metal conveniently pressed to shape with the openings 21 cut in the side wall. In such an instance the resilience of this member serves to increase the sealing qualities of the joint since the nut 14, on seating the cylinder cover D, places the member 17 under a tension.
Thus the member 17 in tending to resume its normal shape forces the ring 16 tightly inv place. Obviously the member 17 need not be of a resilient character but may be of a nonyielding nature.
The siphon 23 may be loosely supportedl in an opening 21, or in order to form a unit assembly with the member 17 mayi be fixed therewith as by soldering in place. Obviousother types of engines where a cylinder head water joint is desirable. It will also be apparent that while I am illustrating my invention in the form of a single cylinder engine, it is obviously in no mannerso limited and the unit shown may be repeated for as many cylinders as might be used in an engine.
Instead of employ-ing a joint ring supporting member as a separate element, I have shown in Figure 4 a modified construction in which the joint ring 16 is located between the clamping nut 14 and the inwardly turned end of the cylinder cover D.
.In both Fig. 1, and Fig. 4, it will be noted that the outer wall of the cylinder head barrel 15 is so fprmed as to permit substantially uninterrupted machining, this being one of the -features of my invention. In some instances u ly any number of Siphon tubes may be pro- Fig. 1 is a sectional fragmentary view, in" flvaled.. 4
While I have shown my invention applied heretofore the outer wall of the cylinder has been formed with an integral annular ro] ection for supporting the sealing ring. uch a structure ives rise to difficult machining of v closure.
