INTERNAL-COMBUSTION ENGINE.

Specification of Letters Patent.

Patented-May 2, 1911.

Application led November 10, 1909. Serial No. 527,198.-l

To all whom 'it may concern:

Be 1t known that I, IJYMAN IVoOnWoRTII. a citizen of the'Unlted States, residing at pression, electricity, or a ,hotbody, and Aburned withair, preferably compressed, the

heated air and products-of-colnbustion constituting or serving as the working-fluid of the engine. i

The object of lny invention is to vincrease the efficiency and improve the fuel economy of internal-cominlstion engines.

My invention consists in certain improvements in the combustioli-chambers, cylinders, cylinder-heads, and pistons of ii'iternalcombustion engines and in certain combinations of parts with coatings or linings of suitable metal as nickel secured in place by electro-deposition to the interior surfaces thereof, confining the hot working-fluid of the engine, as will be more fully hereinafter described in connection with the accompanying drawings.

Figure 1 shows a side elevation, partly in `section, of an internal -combustion engine embodying or containing my improvements.

Fig. 2 shows an end elevation, partly in section, of the engine shown in Fig. 1. Fig. 3 'shows a cross-section A--A .of the combustion-chamber of Fig. 1. Fi 4 shows a longitudinal-section of the cylinder, cylinderhead, and piston Vof an internal-combustion motor with my improvements. Fig. 5 shows a.longitudinal-sectlon of the cylinder, cylinder-heads, and piston of a double-actin gas engine with my improvements. Fig. 6 s ows a side elevation, partly in section, of a, water" cooled gas engineI piston with my improvements. Fig. 7 is an end elev/ation of the parts shown in Fig.

Referring to Figs. 1, 2, and 3, the waterjacketed cylinder 1`mounted upon the engine frame 4 is provided with the water-` jaeketed combustion-chamber 2, and the pis-i ton 3. '.lhe combustion-chamber 2, contains the admission valve 5, the exhaust Valve (i, and the i niter 7, and is suitably secured to the cylin er by fastenings 40. The iston 3 is connected by rod 10, to the crank-s aft 11, mounted in suitable bearings 12, in the frame 4. Upon the crank-shaft 11 is mounted the flywheel 15. The cam-shaft 18 is operated by the gear-wheels 1G and 17 so as to make one revolution to every two revolutions of the crank-shaft 11, and provided with suitable cams and connections for operating the admission valve '5. the i iter 7, and the eX- haust valve as is wel understood in engines ofthe class described. The combustion chamber 2 and iston 3. 'which serve to coni fine the hot. wel" ing-fluid of the engine, are combined with the interior coatings or

linings

20, and 21 respectively of suitable metal as nickel, secured 1n place by electro-deposition. '.lhe combustion-chamber 2 is preferably mude in lengtlrequal to the stroke of the piston more orless, and in inside diameter sufficiently greater than the outside diameter of the piston 3 to be out of frictional contact therewith. In some forms of my invention, the engine piston 3 is made so that ft'docs not extend beyond the guide walls of the cylinder proper; but I prefer to make the piston reach into the combustion-charnbcr 2. a length equal to one-third of the piston-stroke more or less, as shown in Figs. 1 and 2.

Referring to Fig. 4, the combustion space end of the water-jacketed cylinder 1 is counterbored to clear the piston for a length equal to its diameter more or less, and capped by the water-jacketed cylinder-head 1 containing the admission valve 5 and exhaust valve 6. The counterbored portion of the cylinder 1, andthe interior faces of the cylinder-head 1 and piston 3 that confine the hot gases are combmed with the interior electro-deposited linings or coatings in manner similar to the analogous parts 'in Figs. '1 and 2.

In Fig. 5 is shown a double-acting gas engine cylinder with my improvements, the heat exposed parts being suitably cooled by means of the circulation of cooling fluid or water in theusual manner. The counterbored ends of the cylinderl 1, the interior faces of the cylinder-heads 1, and the faces of the piston 3 are combined with the interior coatings s'pectively of suitable metal as nickel secured in place by electro-deposition, which several or

linings

20, 20', and 21 re.

out the casting, is connected by articulated

piping

60, 62, 64 and 66 for leading cooling# fluid thereto; and

connections

61, 63, 65 and ($7 for conducting fluid therefrom. The terminal supply and exhaust connections 66 and 67 respectivel are preferably mounted upon theengine rame 4. Obviously, telescoping pilping might be used instead of the articulate piping for the purposes above described. V

In my invention, the said electro-deposition of the said interior coatin s, facings, or linings -Inay be affected or perfgormed in any suitable manner; preferably by first making the said interior surfaces smooth, bright and clean, then, using an electrolyte of nickelammonium sulfate or its equivalent, an anode of nickel or its equivalent, and a suitable current of electricity; the electro-de- )osited nickelorits equivalent,wbeing then buffed or polished, as is well understood and requires no detailed description.

In my inventionfI regard such metals as cobalt or palladium equivalent to nickel;

though I deem nickel preferable to its analogues, I do not limit myself to nickel. The function of the said electro-deposited interior coatingsis to favor adiabatic-expansion of the hot working gas in the motor.

By the Vconstructions and combinations in internal-combustion engines of coatings o1' linings of suitable metal as nickel secured in place by electro-deposition to the interior surfaces thereof confining the hot Workin iiuid of the engine as herein described, tie objectof my invention is attained.4

Having described my invention, I claim 1'. The combination with an internal combustion en ine, of linings of suitable metal as nickel, e cetro-deposited upon the interior surfaces of the walls in'losing the space 35 formed in the heat exposed.

wherein the workingfluid of the engine is ignited the said lmings having 'suitable means for cooling, substantially as described.

2. In an internal-combustion engine, the combination with the combustion-chamber of coatings or linings of suitable metal as nickel secured in place by electro-deposition to the interior surfaces thereof, and suitable means for cooling said combustion-chamber by circulation of cooling fluid, substantially as shown and described.

3. In an internal-combustion engine, the combination with the cylinder of coatings or linings of suitable metal asnickel secured in place by electro-deposition to the interior surfaces thereof noty in frictional contact with the piston, and suitable means for coolingsaid' cylinder by circulation of coolin fluid, substantially as shown and describefgl.

4. In an internal-combustion engine, the

'combination with the cylinder-head of coatings or linings of suitable metal as nickel secured in place by electro-deposition to the interior surfaces thereof, and suitable means for cooling said cylinder-headV by circulation of cooling-fluid, substantially as shown and described.

5. In an internalfcombustion engine, ,the

combination with the piston of coatings or facings of suitable metal as nickel secured in place by electro-de vosition to the surfaces thereof confining t e hot working-fluid of the engine, substantially as shown and 'described. '6. In an internal-combustion engine, the combination with the piston of coatings or facings of suitable metal as nickel secured in place by electro-deposition to the surfaces thereof confining the hot Working-fluid of the engine, and suitable means for coolin said piston by circulation ofcooling flui n substantially as shown and described.

In testimony whereof I have signed this specification in presence of two subscribing Witnesses.
