.This invention relates to internal combustion engines of the four cycle type and has for an object the provision of a multicyllnder engineconstructed and arranged in I compact form so as ,to occupy a relatively small space.
Another object of the invention is the provision of an engine of this type which will develop a relatively high horse power in proportion to itssize.
Another object o'fthe invention is the pro-. vision of a multi-cylinder engine in which the cylinders are arranged in double formation or end to end with the pistons of two '06 cylinders mounted upon a single piston rod, novel means being provided for insuring true longitudinal reciprocatory movement for the rod so as to reduce liability of piston slap V Another object of the invention is the pro vision of novel means for operating the engine valve, the said means being especiall adapted for an engine of the type illustratedl With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim. In the drawings 1.-
Figure 1 is an elevation of an engine constructed in accordance with the invention, parts being broken away and shown in section and otherparts removed. Figure 2 is a vertical central sectional View.
Figure 3 is an elevation at right angles to Figure 1 with the crank case omitted.
Figure 1 is a top plan view with the.
' normally hold the valves 111 closed position,
outer cylinder head removed.
Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the engine as shown comprises a casing which includes spaced parallel cylinders 10 which are preferably surrounded by a Water jacket 11, while the latter is in communication with jackets 12 and 13 provided in inner and outer cylinder heads 14 and 15 respectively. The cylinders 10 are, of double formation in that they provide compression and explosive chambers 16 at their op osite ends, ignition devices or spark plugs 1 being also provided at each end of the cylinders 10 so as to ignite the com ressed gases.
T e cylinder head 15 is removably secured to the en ine block by means of bolts or studs 18, Wldile the head 14 islikewise secured by bolts or studs 19 so that, both of the heads maybe removed. The water jacket of the head 14 is provided with an inlet 1 port 20 while the Water, jacket of the head 15 is provided with an outlet port2l so that the water jacket may be included in suitable water cooling system.
Entering" the cylinders through the head :14 are piston rods 22 which have spacedoppositely disposed pistons 23 secured thereon. These rods pass through suitable packing glands-24 provided in the head 14, so that the escape ofcompression from the inner chambers 16 will be prevented. The pistons 25 may be provided with suitable packing rings.
In order to insure true axial reciprocatory movement of the rods 22, their inner ends are connected to crossheads 25 which Operate between crosshead guides 26, the latter being secured to the opposite side walls of a housing 27. Connected to the crossheads 25 by means of wrist pins 28 are connecting rods 29 and the latter are in turn secured to a crank shaft 30. The shaft 30 is mounted in suitable. bearings arranged within the,
Each end of the cylinders 10 is provided with inlet and exhaust ports 32 and 32*.
which are arranged upon opposite sides of the cylinders. These ports are in communication with the cylinders 10 through passages 33 and 38 and are controlled by poppet valves 34:. The stems of the valves 34 are surrounded bysprings which act to the stems at the outer ends of the cylinders being engaged by plates 36 which are pivotally mounted upon the engine block as shown at 37. The plates 36 are engaged by the outer ends of valve rods 38 which operate through suitable valve guides and have their inner ends engaged by tappets 39. The inner and their inner ends are connected by cams 43 wl'riclrare mounted upon cam shafts 44. The shafts 44 are driven from the crank shaft 30 by means oli gearing 45.
5 It will be apparent from the foregoing descr ption and accompanying drawings that the engine provides an exceedingly simple construction and is arranged sothat-rthe 20 reserved to make such changes as properly r fall within the scope of the appended claim.
Having described the invention evhat is claimed is vIn an internal. combustion engine, a block,
ahead 'fitting tlie'l'alock,"tlie said block hav- 2:, ing inletand exhaust ports and spark plug openings in the sides of the block, a single p stonirodini-aeaeh cylinder, two separate pistons carried on each rod, one firing on the lip-stroke and the other on: the doom-stroke, 30
and a. means connecting the piston rods with the crankshaft, the said vvalvemechanism .intake and exhaustports beiligcam'ied entirely on the sxdes ofthe engine so that the head is entirely free of any encumbrance. :In testimonywhereofwealiixiour signatures.
