APPARATUS FOR COMPRESSING ELASTIC FLUIDS.

Specification of Letters Patent.

Application filed July 3 1916, Serial No. 107,403. Renewed May 15, 1918. Serial No. 234,763.

To all whom it may concern:

Be it known that I, MIL'roN MCWHORTER, a citizen of the United States, residing at Playas, in the county of Grant and State of and useful Apparatus for Compressing Elastic Fluids, of which the following is a specification.

An object of this invention is the production of an eflicient device and method for compressing elastic fluids so that said fluids may be used to furnish power or for any purpose whatsoever that elastic fluids are used.

Another object is to produce a device of this character of maximum simplicity of construction and operation.

Another object is to produce a device of this character in which the iston will act on some strokes in the capac ty of a prime mover and will also act on other of its strokes to compress air.

Another object is to store some of the energy of the exhaust when the piston is functioningas a prime mover, and also to com ress atmospheric air when the piston is not unctioning as a prime mover,

Other objects and advantages will appear in the subjoined detail description.

The accompanying drawings illustrate the invention.

Figure 1 is a side elevation of an apparatus built in accordance with this invention for carrying out the newly invented meth the gear case being omitted for clearness o illustration.

Fig. 2 is an enlarged end view of the cylinder and exhaust valve operating gear. Fig. 3'is a sectional detail of the piston and cylinder and its parts.

Fig. 4 is an enlarged elevation of the intake valve chamber, a portion being shown in section to expose the needle va ve, fuel port and fuel control valve to view.

Fig. 5 is a sectional elevation on line indicated by LBS-(1)5, Fig. 4.

There is. provided a cylinder 1 of any and a piston 2 worksuitable construction ing in said cylinder and connected by a pitman 3 to a crank shaft 4 on which, if desired, may be mounted a fl wheel 5.

The cylinder 1 is provi ed with a port 6 controlled by a .valve plug7 having a valve stem 8 terminating in a head or abutment 9,

there being a coil spring abutment 9 and the outer end of a guide 11 10 between the to tend to hold the valve plug 7 in closed position to close the port 6.

When relatively low pressures of explosive gases are to be dealt with in the cylinor tank 14, said pipe line being provided with'an air inlet valve 15 and also with a check valve 16. .The exhaust port 12 communicates with a branch17 of the pipe line.

13, though obviously said branch pipe 17 could discharge directly into the receiver 14 instead of by way of the pipe line 13. The branch pipe 17 is provided with a hand valve 18 and check valve 18.

The receiver 14 may be provided with a suitable pressure gage 19 and with a blow off or safety valve 20. The receiver 14 is provided with a discharge pipe 21 having a valve 22, it bein understood that the pipe 21 may be exten ed to the place where the compressed fluids are to be utilized.

Thevalve stem 8 is adapted to be engaged by one end ofa lever 23 which is pivoted at 24 to a bracket 25 connected to the cylinder 1, the other end of said lever being provided with a roller 26 extending in the path of movement of a cam 27 on a cam shaft 28 that is connected by suitable gearing 29 to the shaft 4 as is well understood in the engine art to intermittently open the valve 7.

The cam shaft 28 also operates a governor indicated in general by the character 30, said governor being connected by a link 31 and arm 32 to an air control valve plate 33 hav- 1ng slots 34 adapted to register with slots 35 in the rear wall of a chamber 36 when the valve plate is moved for that purpose, the front wall of said chamber being provided with openings 37 to admit air therethrough. The governor 30 may be of an suitab e type, the action thereof being wel understood, and it suflices to state that when the centrifugally operated elements of the governor move outward they. operate the, ink 31 to move the arm 32 in a direction tojcause the valve plate 33 to close the air openings'35. When the

openings

34, 35 reg:

ister with one another, the chamber 36 communicates therethrough withan inlet port 38 controlled by an inlet valve plug 39, the stem 40 of said valve plug being operated to move the valve plug 39 into port opening position by a lever 41 fulcrumed on the pivot 24. The lever 41 is provided with a roller 42 adapted to be engaged by a cam 43 on the cam shaft 28 so as to intermittently open the valve plug 39 against the pressure of the valve closing spring 44in a manner well understood in the engine art.

The chamber 36 is provided with a fuel nozzle 4.5 connected by a fuel pipe 46 to a suitable source of fuelsupply, said nozzle 45 being controlled by a valve plug 47 normally held closed on its seat 48 by a coil spring 49 as in Fig. 4, suction produced by outward movement of the piston 2 in the cylinder 1 being relied upon, when the valve plate 33 is in open position, to open the valve plug 47 against the pressure of the spring 49 to suck in fuel in a manner well understood in the gas engine art.

The ignition device is indicated in general by the character 50 and need not be described in detail, since any suitable igniting device will answer the purpose and the invention is not limited to the exact construction of said device.

In practice, assuming that a charge of combustible mixture has been drawn into the cylinder 1, compressed and fired in a manner well understood in the gas engine art, it is clear that the exploded chargewill exhaust through the ports 6 and 12 into the pipe line '13 and its-branch 17 and thence into the receiver 14 so as to raise the pressure in said receiver. Other charges will be introduced, compressed and fired in the same way until the governor 30 operates at suflicientlyhigh speed to move the valve plate 34 into position to close theopenings 35.

The next succeeding opening movement of the intake valve plug 39 will not admit any charge to relieve the partial vacuum in the cylinder 1 and consequently, the atmospheric pressure on the valve plug 7 being greater than the combined pressures,

of the spring 10 and fluid inside of the cylinder, said valve plug 39; will open. The succeeding outstroke of the piston 2 instead of being an idle stroke sucks atmospheric air through the inlet valve 15, pipe line 13 andport 6 into the cylinder 1. Then the piston operates on its in 'stroke,to compress the atmospheric air thus sucked in and the increased pressure opens the check valve 16 so that compressed air discharges therethrough into the receiver 14. ,The apparatus. continues, thus in operation to intermittently suck in charges of atmospheric 1 air and compress said charges and discharge them into the receiver 1'4". until the speed of thegovernor slackens suiiicientlyto open function to deliver compressed air to the receiver 14 as before.

From the foregoing it is clear that the piston 2 makes no idle strokes for, when it is not drawing in a combustible charge to fire, it is sucking in atmospheric .air and,

when it is not scavenging the burnt gases, it is compressing the atmospheric air sucked in and discharging said air into the receiver 14.

It is understood that a certain percentage of efficiency is lost in the exploding charges because of exhausting said char es against whatever pressure there is int e receiver 14, but this 1s more than offset by reason of the great percentage of efficiency obtained owing to the utilizing of all of the strokes of the piston and also owing to thesaving of-the pressure of the exhausting exploded gases.

The in the art to which the invention appertains to make and use said invention, it being understood that the construction may be varied within the spirit and scope of the appended claims. I claim:

1. In combination, a cylinder havin exhaust and intake ports, a piston in sai cylinder, valves 'for said ports respectively,

foregoing will enable those skilled means to supply a combustible mixture to the intake port, speed-controlled means to shut ofii the supply of mixture to the intake port, means. to ignite the mixture, a re ceiver, and apipe line connecting the ex-' haust port to the receiver, said pipe line being provided with a check valve and with an air inlet valve. 1
