Be 't knownthat 1, Joanna H. D. Bamoson, (citizen of the United States of Americe, and resident of 'Pittsfiel'd in the county of Berkshire and State of Massachusetts, have invented certain new and useful Improvernents' in Explosive-Engines, of which the following is a full, clear, and .exact description. The object of this'inv'ention which relates to explos ve (gas en ines is to provide such improved an a single member constitutes the means for controlling both the ingress of the'li uid'or gaseous fuel into the'cylinder, and t 0 discharge ,or exhaust of the dead gas therefrom. I

A further object is to seconstruct an engine comprisin a plurality of cylinders that a single'shaftike member, driven from the engine shaft and running at a proper relative speed thereto'serves as the in rose and exhaust controlling means for al of'the cylinders.

A further object is to produce an explosive gas engine of the four cycle t pe at extrcmel y low cost and alsoone in 'w 1011 there" is lessened liability of its becoming deranged or out of adjustment.

The inventionfis'described in conjunction with the accompanying drawings'and is set forth in thehlaims,

In the drawin" -Figure is acentral vertical sectionalrview throu h a four cycleengine constructed in accor anee with this in\'cntion,' auoh engine in the presentinstance being one aving, tour cylinders. Fig. 2 is a'vcrtical cross'sectional'yiew taken axially through any, one of the cylinders showing the valve for such cylinder arid the piston thereof as in the intake position..

ig. 3'is a view similar to Fig. 2 butshowing the arrangements of the parts in the compression stroke of the piston. Fig.4 is a similar cross sectional view showin the parts as in condition for ignition, an Fig. 5 is a similar view but showing the parts in the position for exhaust. Fig. 6 is across sectional and diagrammatic view indicating the relative arrangementof the recesses in the shaft valve and also the successibn of their cooperative actions with the inlet ports.

In the drawings, A represents the on 'no body or casing having a plurality oi oy 'nsimp ified arrangements thatders here represented as four in number, and

indicated by the numerals 1, .2, 3 and 4,-- the same being made by casting with suitable coring-mot-only for the c linders but for 'theieatures-coin 'rised in t e body beyond the;endsj-'- of t e cylinders forming prominent parts of this invention and to be ereinafter particularly described. The engine bodyhas a. bore B therein located beyond the ends of the cylinders and having its-axial line at right angles to the arallel ixes ofell of the, cylinders; and rornthe said boreopenings a are formed within thebody transversely relatively to said bore connectin the latter with the upper e'nds of thecy inders. The body has a narrow and-closed intake chamber C therein extending longitudinally thereof which has a length cor-res onding to' the distancebetweem thedotte lines :11, a! in Fig. 1; and from this' common' intake chamber with which the gasolene and air supply conduit D is connected, ports I) individually corresponding to. the several cylinders lead to communication with the aforementioned bore. The engin'ebodyalsc has in its upper portion andmore or less nearly opposite the 'inclosed intake-chamberC an exhaust chamber. F, the length of'which is uniform with that fof the c amber C and from which chamber F lead exhaust ports f corresponding to the respective cylinders, which ports terminate in communication with the bore 3. The intake and exhaust ports 6 and f for each cylinder as well as the cylinder and bore-connecting o enings a are so lo? cated' that they woul -be centrally intersected by a plane transverse of the engine body comcidentwith the axis of the respective cylinders with which these-ports. and

- openings correspond.

J J represent pistons in the r tive' 'cylindersaand i 1' represent pitman r0 s-connecting tie pistons with' the cranks ofthe engine sha'ft,-'which shaft .with its cranks are inclosed in the crank casek.

The distance between the mtakeand exhaust ports I) and f is fractional of the circumference or circular wall of the boreB, that is in the present instance, in which there are four c linders, ,such distance of separation of t e ports is 'approximately one fourth of the circular extent of the wall of saidbore. l.

The valve device which contrpls the ingross and exhaustfor all of the cylinders consists of a cylindrical bar or shaft-like part L closely fitted in the aforesaid bore ut free to rotate therein, the same having suitable end bearings therefor in the engine body. This shaft has recesses m therein which extend but fractional of its circumference at different portions of its length corresponding to the regions of the aforementioned intake and exhaust ports b and f as well as the channels 9 and the bore and cylinder connecting openings (1. These valve recesses m which are at ifierent parts'of the length of the shaft-like member L have their locations at different places around the body of such shaft like valve so that they will in proper succession register with the sets of ports, channels and openings appurtenantto each cylinder and-in accordance with the practice of four-cycle explosive en- 'gine construction, the shaft-like valve L is 2 to 5 inclusive: In Fig. 2 it is seen that at v the time'the piston is at its upper osition I forintake the shaft-valve recess m orm's a duct or wayfor communication between the intake port b and the bore and cylinder opening a so that as the piston recedes in the c amber a-full charge may be takenim-Ithe means of exhaust at this time being closed. In Fi 8. the 'piston being understood as procee ing on its upstroke or-compression,

the shaft valve recess m has such a position that the communication betweenthe intake port and the cylinder 'and'exhaust portiis closed. In Fig. 4 the valve is shown as having slightly farther rotated, but still insufficiently far as to open connection between either the intake or exhaust-ports with the cylinder,-the conditions here being such as .tion (as insured by 'the spark plugs "cylinder 1 followed by t established at the time of ignition. Fig. 5 represents the relative position of the parts fo lowing ignition when the piston has been driven to the limit of its working sfrokc,-and

the conditions are established for the enhaust of the dead gases from the cylinder,1t here being seen that the shaft valve .recess in forms communication between the channel 1 -(which'is atall times open to the cylinder by reason of its having connection'with the opening a) and the exhaust port f for the cylinder under consideration; and the length of the are shaped recess m issuoh as to leave the passageway open for the exhaust until such recess m, under the turning of the shaft-valve, derives a position for opening communication between theintake port and the cylinder for a fresh explosive charge.

The valve recesses in appurtenant to the respective cylinders and located at different laces along the length of the shaft-valve, rthermore, havetheir locations relatively the one to another at diiierent laces around the circumference of'the sha t-valve-so as to secure the operations in the several cylinders in, proper relative times; and the arrangement of this engine as the same has been designed by'me is such that the igni- I? having wiring and enerator. connections and .o erating in COIlJllIlCiLlOli with a timer, not

will take place in 1e firing in cylinder 2, the ignitionin cylinder 4 next transpijring after which the explosive action occurs in cylinder 3, this operation being repeated time-and time again. Such succession of s own, but all as usual} operations need not,-however, be.adhc'red to; ;and the invention is not-limited to an' engine of any particular number of cylinders, as the idea of means hereinabove described -in conjunction with the illustrations provided may be adapted to engines having any number of cylinders within reasonable range, requirement of changes therefor be- A ing those of detail and-of a character manifest to any designer skilled in the art'to which this invention ertainsp The shaft 'valve is s own as having a assa Q'axially there'through from on to en ,'the objlect of which is to provide a means for tie cooling of the shaft by atmospheric air, a current of which under-the running of the shaft will be induced through the valve device.'
