' spianata canapa o, :am mi. 425,440. f
To all whom it may commi.' j 5 Beit known that I Jomv HENRY S y a citizen of the United States, residin all. m' chester, in the county of Ches eld and` State of Virginia, have invented a new and useful Engine, of which `the followingnis a speciication. .v j. This invention relates to the manufacture providedY with a fluid jacket,
eted steam engine cylinders.
The invention further produced by such Inanufactiirei y,
It is awell known fact ,that where a fluid passage such 4as the Water jacket of a gas' engine cylinder, is attempted to be cast there is ,at all times more or less'doubt about the exact position of the core durin the casting. lNeither chaplets nor any ot er means has been found efficient to maintain the cores' of the water jacket in correct position and atY times cylinders havebeen cast in which the cores were so far'out of osition as to greatly weaken the cylinder an cause the saine tol burst without warning.
ob'ect of the presentinventionjs to obviate 't e necessit for usin cores gin the construction of suc aQcylin er and ,to so construct the samethatit may be cast with no other core than that of the c linder bore.
A further object of the invention is to rovidev a cylinder of thecharacter descri ed' with-.an exterior of high tensile strength. It is usual in cylinders ofj this description, and in fact necessary in the usual construction, to cast the cylinder out of metal having easy flwing properties when molten. This metal g what is claimed is as a rule is not of-great'tensile strength, 'and it is to obviate the-weakness occasioned:
thereby that is the second object of this in-y vention as expressedgabove.
' The invention consists in'general of a cylin der provided with fluid jacket recesses on' the exterior aid a' casing shrunk thereovenA ln the accompanylng'drawings the viewswr are merely typical of; any form of cylinder of the above descri tion, and are to be taken onl as such. or the purpose ofbetter un erstandng the'device, however, ya somewhat' specilc .description is necessa and with this in view like characters of relf'rence indicate like arts in the views.
. Figure 1 ows an elevation of the views relates to the article a second r1 assembled, the outer Icover being in section.
Fig. 2 is a perspective view of the same. n the type of cylinder here shown the numeral 10 indicates the body of the cylinder. Ribs 11 extend therearound, the rib 11 at the lower art of Fig. 1 being at the usual oint at whic the water jacket ends. At 12 ,is indicated thel cover for the fluid jacket recesses or essa' es 13. At 14 are shown bosses on t e cy der which may be used as a means of securin a head thereto, while at l5 are the bosses W erein are made the usual inlet and exhaust passages.
In the method of constructing the device, the same body 10 is cast in such manner as to uip from the main portion of the bo y and t us leave the recesses 13. The body portion 10 may then be turned u or left rough as desired, but it is essential t at the ribs 11 should be so finished as to resent a pro er smooth surface and it is pre 'erred that all)of 'the projecting 'arts should lie in the saine cylindrical su ace. This body ortion is preferably made of cast-iron, but it may be made f any other metal having easy ilowing properties when molten. vThere is then ipre- -pared a cover 12 which is preferably ma( e of slightly smaller diameter than the diameter of the cylinder in whose surface lie the surfaces of the ribs 11 and bosses 15. This cover is preferably made of wrought steel ol' hi li tensile strength and is heated to expand t ie same when placed over the body of the cylinder and cooled thereby setting up initial tensile stress in the exterior and initial coni- 'pressive stress in the body portion.
l An engine cylinder comprising a body portion havin an annular rib at one end'thereof, lx intermediate the ends, a lug pro jecting above the' second rib adjacent the same, and a` metal cover shrunk over said body su ported on the ribs and bearing against t elug.
In testimony that l claim thel'oregoing as my. own, I have hereto aflixed my signature in the presence' of two witnesses.
