CYLINDER con inc'riou AND THE Linn.
Application filed November 17, Serial No. 424,?35.
This invention relates to engine cylinders and the like and refers more particularly to the joint which is formed between the cyl inder or cylinders and the cylinder head or cover and the invention is appli'cable in every case where it is necessary to make a fluid tight joint by providing machined surfaces at the top of the cylinder or cylinders or the like and on the underside of the cylinder head or cover and wherein these parts are forced together by pressure such as is obtained by bolts passing through them.
In such joints as at present constructed. for instance in connection with the cylinders of internal combustion engines, it has been the custom to provide plain surfaces at the top of the cylinder or cylinders and on the underside of the cylinder head, the said surfaces extending around the cylinder or cylinders and being of a considerable width owing to the provision of a water jacket. The parts are held together by bolts which are adapted to draw them together, but it is found a matter of considerable difliculty to make a satisfactory joint as leakage is apt to occur about midway between the bolts.
The object of the present invention is to overcome this difficulty and in accordance therewith at the top of the cylinder or cylinders or at the underside of the cylinder head or cover, or both, we provide at the periphery a continuous narrow facing strip, and similarly a narrow facing strip is provided which encloses each cylinder and valve chamber, whereby when pressure is applied by the bolts the metal formingthe strips adjacent the bolts can be crushed slightly so as to enable a sufficient pressure to be objgailned at those parts which are between the The widths of the facing stripsmay be greater at those parts which are midway between the bolts than are the widths of the strips adjacent the bolts.
Washers or packing may be inserted be tween the facing strips.
The provision of facing strips at the edges of the casting or castings, results in a cavity being formed at the joint when the two parts are secured together, through which cavity the cooling water can flow, thus greatly facilitating the cooling of 'th'e metal at thejoint and minimizing expansion and consequent distortion due to heat. Referring to the dr'awing s'z Figure 1 is a fragmentary view in plan.
Figure '2 is a View in sectional elevation on line X-X of Figure 1.
In the construction illustrated as applied to a cylinder for an internal combustion engine, the upper surface 1 of the cylinder is provided. at its extreme periphery 'wi'th a narrow facing strip 2 made integral with "the cylinder casting. I The width of this facing strip may be constant throughout or may be at a maximum at those pointswhieh are most distant from the bolts as shown at 3 in which case the width of the facing strip is at a minimum at those points which are adjacent to the bolts as shown at 4:. It will be understood that this facing strip is at the extreme periphery of the casting and in line with the outer edge of the water jacket.
A similar facing strip is provided around each cylinder as shown at 5. the width of each of these inner facing strips also may be either constant throughout or greater at those points which are distant from the bolts and at a minimum adjacent the bolts.
The underside of the cylinder head is similarly provided with facing strips as shown at 6 and 7 which are adapted to register with those upon the upper surface of the cylinders.
The cylinder head and cylinders are assembled together in the usual way and pres sure is applied by means ofthe bolts. The facing strips are such that this pressure is able to crush slightly the metal adjacent the bolts whereby a sufiicient pressure is obtained between the facing'strips at those points whichare between the bolts 12 which extends through the holes 13 in the cylinders and cylinder head and are secured by nuts on the cylinder head in the usual manner.
Copper, asbestos or other washers 8 shaped. similarly to the facings, may be inserted between the facing strips in which case when the nuts on the bolts are tightened, those parts of the washers which are adjacent e belts are compressed allowing the pressure from thebolts to be transferred to the points midway between the bolts. v
The facing strips may be produced either by casting or by machining away the metal to a depth of say one eighth of an inch or more, leaving a cavity between the two parts into which the water may circulate and thus facilitate cooling of the adjacent parts. 1
Holes such as 10 are provided in the metal and such as 11 in the washers or packing if such is used, these holes allowing the water to circulate freely. The holes in the metal and in the packing need not be in register as shown but may be staggered.
What we claim then is 1. A peripheral joint. for hollow structures having one of its contacting faces provided with a pair of undulating facing strips and spaced securing members disposed between the facing strips; the undulating facing strips being narrow adjacent the holes for the securing members and extending to a greater width intermediate thereto.
2. A peripheral joint for hollow structures having both of the contacting faces provided with a pair of undulating facing strips and spaced securing members disposed between the facing strips, all the undulating facing strips being narrow adja cent the holes for the securing members and extending to a greater width inter mediate thereto.
3. A peripheral joint for hollow structures having one of its contacting faces provided with a pair of undulating facing strips and spaced securing members. disposed between the facing strips; the undulating facing 40 strips being narrow adjacent the holes for the securing members and extending to a greater Width intermediate thereto, and packing between said facing strips and the other face of the joint.
4:. A peripheral joint for hollow StllllC-l tures having both of the contacting faces; provided with a pair of undulating facing strips, spaced securing members disposed between the facing strips, all the undulating facing strips being narrow adjacent the holes for the securing members and extending to a greater width intermediate thereto, and packing between the said pairs of facing strips.
In Witness whereof we affix our signatures.
