Specification of Letters latent.

Application filed March 24, 1917. Serial No. 157,108.

T 0 all whom it may concern Be it known that L-CnliiinnsR. SHORT, a citizen of the Dominion of Canada, and resident of Detroit, Wayne county, State of Michigan, have invented certain new and useful Improvements in Hydrocarbon-Motors, of which the foilowing is the specification. 1

This invention relates to hydrocarbon motors, and particularly to the general arrangement and construction of its various its jacket, its head, valves and actuating mechanism.

One of the objects of this invention'is to rovide a motor of the multi-cylinder type, aving a plurality of integral cylinder-liners or' barrels, detachably arranged within a cylinder jacket.

; Another object of this invention is to provide a motor having a built-up cylinder and jacket construction, which is comparatively inexpensive and simple to manufacture.

Another object is to provide a motor having the outer wall of the cylinder jacket formed integral with the crank case of a comparativel light material such asaluminum, with the cylinder bore formed of a heavier material such as iron, and detachably arranged within the jacket. The cylinder head is preferably detachably mounted in position with an overhead valve mechanism which is adequately inclosed a memher which is also formed of relatively lightv material such as aluminum. I

Another-object of the invention is to provide a motor of the class mentioned above wherein the cylinders are less subject to disalinement on account of expansion than heretofore. This is accomplished in the embodiment of the invention shown, partly by forming a plurality of the cylinders in a single liner or block of a metal which has a low coefficient of expansion relative to that of the metal of the casing. The group of cylindersthus constructed cannot be carried along with the casing as the latter expends but remains as'a unit and any possible movement oi the group of cylinders will be approximately in accord with the expansion of the crank shaft. In other words tht movement of the casing as the engine heats up, which tends to spread the cylinders apart somewhat in j'the manner in which a faiiopens, is. off-set by constructing a plurality of the cylinders in a single unit liner. liFor the same general purpose, the liner is itself constructed and arranged to form a acket passage for cooling liquid which extends about the firing end of the cor-re spond ng cylinder or cylinders thus reducing the expansion materially below that which Patented N0v,15, 1921. v

would take place were the casing itself extended to the firing end of the cylinders to form a jacket Wall. By terminating the outer wall of the liner not far from'the firing end, the necessity for the expensive coring processes incident to the usual constructions wherein the casing and cylinders are inte ral is avoided,

he visible result of these features of in.- ve ition is a material reduction of knocking, which in ordinary constructions is due,

partly at least, to the disalinement ofthe connecting .rods with their pins asthe cylin ders s read in fan-like fashion, as heretofore descri ed.

The various objects, and the construction and arrangement of the various parts will clearly appear fromthe following specification, taken in connection with the drawings in which:

Figure 1 1s a vertical transverse section of vertical type motor embodying a form of my invention;

Fig. 2 is a side elevation, with portions lligoken away, of the motor illustrated in Fig. 3 1s a transverse horizontal section,

substantially along the line 8-3 of Fig. l,

showing one block of three cylinder bores removed.

Fig. 4: is a side elevation with portions broken away of an assembly of themotor crank case, the cylinder blocks, the jackets and a valve rod cover.

Fig. 5 is a transverse vertical section of the assembly illustrated in Fi g. 4; and

Fig. 6 is a transverse vertical section, with some parts removed of a V type motor embodying my invention.

Referring to tliedrawings, 10 and 11, re-

spectively, illustrate the upper and lower sections of a crank case or motor base formed of a relatively light material, such as alumi num or an, aluminum alloy, in which may be mounted", in the usual bearings, a crank shaft 12 and a cam shaft 12.

A chamber which is adapted to form the outer wall of the jacket of the cylindermay be made of the same material as the crank case and formed integral therewith, as an upwardly extending portion 13. The

trated in Fig. 6, the

'20 22 mounted Within each he inner wall of the cooling acket ischamber 13 is provided with an inwardly extending flange, or portion 14 having a plurality of bosses 15. In the six cylinder motor, illustrated, two blocks or sets of three F cylinder liners or barrels 16, are adapted to be arranged within the chamber 13. It will be noted that the upper end of the liners* 16 are formed with a shoulder 17 13, and they are also formed intermediate their ends with a flange 18 which is adapted to reston the internal flange 14 of the chamber with a suitable gasket 19, therebetween. In the form illusliner blocks 16 have the flange 18 formed adjacent their lower ends, and the liners may then be secured in position by means of a plurality of bolts 20, with the usual piston 21. and connecting rod of the cylinders.

formed by the cylinder barrel 16 and its outer wall by the chamber. 13. These barrels are preferably formed of a heavier material, such as iron, or steel. The usual spark plugs 24 may be threaded laterally in the upper portion of the cylinder barrels.

By theconstruction described, it is evident that' that portion of the wall 13 which lies between the flange 14 and the shoulder 17 may be made of a minimum thickness, since the stress is for the most part transmitted directly from the cylinders to the casing 10 through the rigid connection afforded by the flange or shoulder 14, the flange 18 V and the bolts 20. A head 23, formed either of a heavy or light metal a's desired, and provided with the usual intake and

exhaust ports

25 and 40 cooling jacket 26, is adapted to be arranged across the topof the cylinders 16 and to be detachably secured in position such as by bolts27." A' valve mechanism comprising puppetvalvemember 28, spring 29, retaining plate 30 and collar 31, may be provided for each of the ports 25. It will, of course, be understood that suitable connections are provided between the head jacket 26 and the cylinder chamber 13.

Eaehvalve mechanism is provided with a rocker arm 32, mounted-on a shaft 33 which is supported by an arm 34, detachably secured, as by a bolt 27 to the head 23. One end 35 of each of the rocker arms have a curved face adapted to contact with the upper end of a valve member 28 and the op posite ends 36 of the rocker armsare proing bolts 42 to the crank case 10. The tappets 39 are, of course, adapted to be operated by cams 43, formed on the cam shaft 12'.

The plate 41, and another dome shaped plate 4.4-, which is suitably secured across the'top of the head 23, and preferably formed of a light material, such as aluminun], are adapted to completely house the valves and their actuating mechanism.

It will be noted from the above description that I have provided a built up motor construction, the various parts of which may be very easily and comparatively inexpensively manufactured, assembled and disassembled.
