ENGINE CONSTRUCTION.
Speoication of Letters Patent.
Application led .T une 19, 1911. Serial No. 634,063.
To all whom it may concern l `Be it known that I, CHARLES H. BARrLn'rr, a citizen of the United States, and resident of911 East Jersey street, Elizabeth, Union county, State of New Jersey, have invented certain new and `useful Improvements in Engine Construction; and I -do hereby declare the following to be a full, clear, and exact description of the invention, such as iwill enable others skilled in the art to which it appertains tomake and use the same.
'This invention relates to engine construction,l and particularly to a form of construction especially adapted to single or multiple 15 :cylinder internal combustion engines in which lthe working cylinder of each unit is ar'ran ed in tamden with an air-compressing cy'lin er.
One object of the invention is to provide an engine having a sup orting bed-plate or foundation structure, preferably common to all the Icylinders in the case of a multiple cylinder engine) on which the tandem cylinders are separably supported so that the engine may be readil assembled or dismantled without distur ing the bed-plate or foundation structure.
In the preferred 'construction that portion" of the foundation structure which surrounds `and supports the compressing cylinder is of such configuration that a closed receiver for the compressed air is formed between the wall of the compressing cylinder and the surroundinr support. In engine construc- .ftions of this kind heretofore customary, it was usual either to have the foundation structure made integral with one of the cylinders or simply to ian'ge the lower end of.
the bottom cylinder and bolt it to the foundation structure or bed-plate; so that if the construction was mechanically strong as in the first case, easy assembly'and com-plete dismantling of parts were impossible; while if these features were obtained, as in the second case, the construction was mechanically weak unless an undue amount of metal was used to sec-ure 'the proper strength.
In the construction herein disclosed as an example, the upper cylinder, usually the working cylinder, is formed in one piece and is tlanged and bolted to the other cylinder so as to be readily `connected thereto and disconnected therefrom. The foundation strue- I' upst-anding sleeve or housing into which the compressing cylinder fits, so as to be supported at one end by the bed-plate and also at a point intern'lediate of its ends by the sleeve or housing, whereby the cylinder may be readily set up or taken down, while it is rigidly supported when in position without the use of an undue amount of metal. Furthermore, the housing and the compressing cylinder form between them a receiver' for compressed air, the abutting parts being machined to make a tight lit. This construction may be applied to a vertical or a horizontal engine of any number of cylinder units, wherein each unit may have two cylinders or any other suitable number. Furthermore the engine may work on a twostroke cycle, or any other cycle wherein explosive gas is vignited by yignition devices, or wherein a vapor of heavy oil is spontaneously ignited by contact with highly compressed air.
The accompanying drawings alud descriptionare directed to an v engine working on a two-stroke Diesel cycle, and to an engine having six cylinder units, cach comprising a working cylinder, and a compressing cylinder of larger diameter, in tandem arrangement; but I do not limit myself to this specific embodiment or to the details of construction, since it will be evident that the essential features of my invention may be applied to various kinds of engines and to The bed-plate or foundation structure is made up of a trough-like structure 1 extending substantially the whole length of the engine, and the part 2 likewise extending the j length of the engine, and fastened to the trough-like structure by bolts or in any suitable way (not shown). The part 2 has an upwardly projecting sleeve or housing 3 for each unit into which l,is fitted the bompressing cylinder 4 so as to be'supported at 5 and 6. The flange 7 of the compressing cylinder les 4 is fastened tightly to the sleeve at 6 tay/'1.19
26. A of a working cylinder 9 by means of a suit- "boia ai, Whiie the joint at. is made iight by packing or gaskets, for example, so that the annular space S formed between the coinpressing cylirider 4 and the sleeve 3 is adapt- 'ed to hold lightly compressed air without leakage thereof to the crank case'or to the atmosphere. The working cylinder 9 is fastened by means of a flange 10 and bolts 30 to the topof the compressing cylinder. The vt-orking cylinder may be'provided with a jacket 11, whereby .water or other coolingA medium is circulated in the space 12 by any well known means. In each unit the working piston 13 and the compressing piston 14 are arranged iii echelon in their respective cylinders, and they are connected to the enygine shaft 15 in `any well known manner .such as by the wrist pin 16, pitinan 17 crank pin .18, and crank 19. The engine sliaftvalso carries the .fly-wheel 32. vAny suitable lubricating system maybe used.
' For a two-stroke Diesel cycle, the operation of thee'ngine during the period of running is as follows: At the proper point of the up-stroke, fuel is admitted into'the top ablevalve, indicated at 20. Upon combustion of the fuel, the pistonsare forced down and at a definite point of the stroke the products of the combustion rush out 'of the 'exhaust port 2 1 into the common exhaust pipe 22. During the period that the exhaust 'port is uncovered, scavenging air compressed to the vproper degree isl admittedinto the working cylinder by the. inlet valve 23 in .plpe' 24 -which leads vfrom the receiver 8;
i ated from the engine shaft by amrod v25, or it vfeo ` which is' entrapped in the working cylinder. Jupon'closure ofthe exhaust port is comto .a-` pressure sufciently high to spontanevte may be actuated in any lothersuitalole manner. The scavenging air forces t" remainiug products of combustion from the work- 'iiig cylinder, while that part of the air vpressed during the upstroke of the engine oiisly ignite the injected fuel.
During-the down movement ofthe working piston, air from the outside is drawn into the compressing cylinder 4. through the port 33, valve 34, and port 35 while'the discharge valve 27 is kept closed by the pressure of the air in the receiver 8 on thev other sideof 'p ce.
.the'valve During the 11p-stroke of the engine the' air is lightly compressed in the compressinr cylinder, and when its pressure, becomes suiliciently high the discharge valve 27 automatically opens and'allows the air to passthrough port `26, pipe 28 and opening'29 to the receiver 8. During the upl'stroke of the compressing piston the inlet valve 34 is kept closed as a result of the pres-v sure on its inside face. This method of operation is Well known in the art and need .not be llllrtller elaborated.
is inlet valve may be mechanically actu` and the compressing cylinder.
minacce 'I'o dismantle any lunit of the engine, the exhaust pipel 22 isdisconnected fromy the particular cylinder, the corresponding bolts 30 are removed, the air supply pipe coupling 36 is disconnected and the operating mecha-l nism is'disconnected, whereupon the working .cylinder may be pulled bodily outof the compressing cylinder. The compressing cylinder may then .be taken out after the bolts 31 and pipe 28 have been disconnected.
In this way both sets of cylinders may beA dismantled without disturbing the foundation structure, and the working cylinders may be dismantled without disturbing the compressin cylinders. C
Having t us described my invention what I claim is:
1. In an engine construction, a foundation structure including a crank case, an. air compressing cylinder, a working cylinder in tandem arrangement with the compressing cylinder, and a supporting housing for the compressing cylinder, an air reservoir or receiver located between the compressing -cylinder and housing, connections between vthe air receiver and working cylinder for admitting compressedv air thereto, and a valved connection between the air receiver, and the compressing cylinder.v
