INTERNAL-COMBUSTION ENGINE.

Application led Hay 5, 1922. Serial No. 558,640.

To all hom it may camera:

Be i known that I, CLYDE ALLEN SPEN- CIB, a citizen of the United States, and resident of Hollywood, in the count 1 or' Los An eles and State of California, ave invente a new and Improved Internal- Combustion Engine, of which the following ie a full, clear, and exact description.

-"siderable diliculty has been experienced in- My invention relates to an internal combustion engine and aims to 'provide a device of this character embodying certain novel construction over devices of this type It present manufactured.

' 1t is a well appreciated fact in connection with internal combustion engines that concident to the vibration caused by the reciprocation ot the pistons. Also considerable dilicult-y has been experienced with respect to the connecting rods, wrist pins, cam shafts, poppet valves, etc.

Thus it is an object of the present invention to provide an internal combustion engine in which the explosive force will be primarily translated into rotary energy so that the objections arising incident to reciprocation of the parts will be overcome.

A further -object of this invention is that of constructing a device of the charac- 'ter stated by means of which it will be feasible to eliminate parts heretofore restroke, and secure high enabled to cut down the weight of the device to a minimum, make everyy stroke a power compression within the cylinders.

l Further objects of this invention will appear `in the annexed specication taken in connection with the drawings which latter illustrate one practical embodiment of the slmeandnwhich;

Figure 1 is a side elevation of an engine, embodying my improved construction.

Figure 2 is a transverse sectional view taken 'on the line 2-2 of Figure 1.

' Figure 3 is a fragmentary enlarged sectional view of one of the cylinders.

Figures 4 to 8 are diagrammatic views of the positions assumed by the parts dur.- ing4 the various intervals of one cycle, and

`igure 9 is a further diagrammatic view of the device and showing one practical embodiment of the ignition system which may be associated therewith.

Attention is primarily invited to Figures' 1 and 2 in whinh it will be seen that the reference numeral 10 indicates the' base upon which the engine is supported by means of suitable standards 11, it being noted that these standards provide bearings 1Q by means of which a hollow shaft 13 is rotatably supported, the latter in the embodiment illustrated, carrying a flywheel 14 adiacent one of its ends.

It will also be seen that one of the standards 11 carries an annular gear l5 presenting outwardly extending teeth 16, and the shaft 13 carries a sleeve 17 formed with outwardly extending spaced arms 18, adjacent its ends.

A pipe 19 is rotatably carried between each of these pairs of arms, and a cylinder 20 is secured to each pipe, it being noted that one end of the said pipe is extended beyond its supporting arm in the form of a trunnion 29, and has a gear 21 aflixed to it,

,the teeth of whichmesh with the teeth 16 of the gear 15.

Thus it will be appreciated that upon the shaft 13 being rotated the arms 18 will also be rotated, and incident to the fact that the cylinders 20 are carried by these arms, said` cylinders will revolve about said shaft as a center. .However, due to the fact that the gear 15 is stationary, and that the gears 21 connected to the cylinders mesh with the gear 15 it will be obvious that the cylinders will be rotated about the trunnions 29 as axes simultaneously with their rotation' -23 enci-rcles the tube adjacent these openl ings. A carburetor 24 is connected to the manifold, and thus it will be obvious, assuming that a partial vacuum exists within the shaft 13 that a fuel mixture will be introduced, which will enter the Said shaft through the openings 22, the mixture iowing thence through the Apipes and so into the pipe 19 connected to the cylinder 20.

Thus it will be obvious as in Figure 3, that when the cylinders are swung a centrifugal action will be set up which will result in a suction within the same and within the pipes 25 thus causing a corresponding suction in the shaft 13 resulting in the production of a fuel mixture on the part of the carburetor which fuel mixture fiows to the cylinders. In other words, it will be appreciated that the pipe 25 acts as a centrifugal blower forcing the mixture into the cylinders, and drawing the same through the tube, manifold and carbureter. A lso iniFigure 3 it will be noted that a `free piston 26 is slidably positioned within the cylinder 20, and the ends of this piston are preferably reduced to provide deflecting portions 27. The pipe l2) communicates with the cylinder at points preferably intermediate the ends ot the same, and. open iugs 28 acting as exhaust ducts are disposed to each side of the trunnion Q9 with which the gear 21 is associated. By this construction it will be obvious that when the piston is iu either end of the cylinder, fluid will be free to/flow into the interior of the said cylinder, through the pipe 19, the said fluid I heilig deflected in the manner indicated by the arrow, by virtue of the deflecting por- Vtio`us-27 of the piston. Also it will be obi'ious that as the piston'moves Within the cylinder the outlet end of the pipe 19 is sealed at all times with the Aexception of those. intervals during which the piston is iu one of its extreme positions'within the cylinder. Further it' will be obvious that bcl'ore the piston reaches this position the sume will uncover one. of the exhaust openings 28 so that-any products of combustion within tlz' cylinder will be free to escape prior to that time at which a fresh fuel mixture is being introduced into the same.

Now with a view of iguiting the fuel mixture within each of the cylinders' it willbe appreciated that any suitable means may lrev employed, but l preferably utilize the eir- 'cuitvand structure. shown in Figure 9. In

this View it will be seen that l may employ a suitable source .of high tension current 30 from which high tension leads v31 extend` it being noted that one lead of this current is preferably grounded as at 32. A lsuitable timer 33 may also obviously be provided. The high tension leads 31 terminate. in contact strips 34 and a ring 35, and wipers 36 bear against this ring and are 'cylinders connected by means of suitable leads 37, to similar wipers 38 arranged adjacent to the Thus it will be obvious that when the wipers 36 are bearing against the strips 3l and the Contact strips 38 are bearing against the contact strips 39 associated with the cylinder current Will be passed through the leads 40 associated With the latter and thus a spark will be produced by the plug 11 within the cylinder.

Now referring to Figure t it willbe seen that the parts are diagrammatically illustrated as being in a position in which an explosion is occurring in the A end of each of the cylinders. This explosion will result in' the piston 26 in cach cylinder being forced towards the opposite end B of the cylinder, it being appreciated that any products of combustion within the B end of the cylinder have passed through the proper opening-Q3 and that a combustible mixture is also passed into this end of the cylinder through the pipe 1S). In other Words the explosion will cause the cylinder to move while the piston remains relatively stationary, which is particularly the case where a light cylinder and a very heavy piston, of the nature illustrated, are employed. Thu-s when the piston moves to the position shown in Figure 5 the mixture in the B end of the cylinder will be compressed while the exploding'charge will still be forcing the piston in the direction indicated by the arrows. When the parts reach the position shown in Figure t it will be appreciated that the products of combustion within the A end of the cylinder will be escaping through the proper opening 28 provided for this purpose, and in this instance the mixture within the B end of the cylinder will be compressed to almost its fullest extent, this limit ojl compression being reached in the position ol the vparts as shown in Figure i. ln this position it will be seen that the products ol'Y combustion have been exhausted from within the A end of the cylinder, while the l'uel charge within the B end of the cylinder has been completely compressed, and as iu Figure S, ignition will now occur in the l end ot the cylinder, and the entire cycle olI opel-:dien will-be accordingly re- 'ersed. i

v 'l`lius in the embodiment illustrated in which two cylindersare employed, it will be understoodthat two explosions will occur in each end of each cylinder during each complete revolution of the shaft 13. Thus eight explosions occur for each complete revolution of shaft 13, and it will be appreciated that the motion of the arms and cylinders is tobe predicated to the fact that incident to the reaction of the cylinder to the movement of the relatively heavy piston the former will be caused to move in a positive manner as aforedescribed.

minces Freni lthe foregoing description, it Will be apparent that the individual explosions Within the kcylinders Will create c force which will rotate the supporting' member including the arms 18 thus imparting c similar movement to the shaft 13 and the iiy Wheel ill, end that rotation oi said supporting member Will, through the gears 15 end 21, ceuse the cylinders to revolve about their trunnions 29. lue to the high velocity stoodtliat numerous modifications of structure and4 rearrangement of' parts may readily be resorted to Without. in the least departing from the scope of my claims; Which are;
