STATES PAUL MARCHETTI, OF SAN-FRANCISCO, CALIFORNIA.

ENGINE.

Application filed April 17, 1924, Serial No. 707,21f1. Renewed November 15, 1927.

rlhis invention relates to piston engines in general'but to internal combustion engines of this type in particular, and has to do wlth a means of dispensing with the crank shaft common to such engines.

'l he principal object of my invention is to provide a novel mechanical arrangement for` transmitting. the power from the pistons to a straight engine shaft without the use of cranks or eccentric straps or the like, thus doing away with the usual babbitted bearings of these parts and their frequent adjusting and renewal. y

l attain the object outlined by the engine construction shown in the accompanying drawings, and in which Figure 1 is a sectional elevation of one form of (my engine taken transversely through the main shaft;

Figure 2 is a longitudinal4 central section of the engine as seen in elevation;

Figure 3 is a diagrammatic representan tion of a means of increasing the effectivenessof the power stroke of my engine;

Figure @t shows a modification in the cross head guides g, 4

Figures 5 and 6 show modifications in the forni of my driving flange; and

Figure 7 shows a modified arrangement of the driving flange rollers. i

By a. general review of the drawings it will be seen that my invention consists es` sentially of any number of cylinders with pistons therein each having a fixed piston rod working back and forth in cross head guides to stabilize'them, and each rod carrymg rollers at its inner end bearing against a special shaped driving flange secured to the shaft for transmitting power thereto.

' lin the drawings, (l) is the engine casing, (2) the straight main shaft passing through the casing and supported on roller bearings at (3). At (4L) is a ywheel, here shown as being secured to the shaft outside of the casing, though it may be positioned inside of the casing if the latter is made large enough.

Projecting from the casing are any number of cylinders (5) directed toward the shaft though not necessarily on strictly ra dial ylines for they may be offset slightly as indicated in Figure 3 with advantages 1n some cases. rllhe cylinders may be distributed around the shaft or kept von thenpper side only as illustrated, and in this case they would preferably be disposed at about'45o to one another, and of course there may be any number' arranged along the shaft. though one set only 1s shown as being sul'hcientljv illustrative.

Within each cylinder is a piston (6) having a piston rod (7)' rigidly mounted thereon and stabilized against side motion by a cross head (8) working in slots (9) in the cylinder walls.

` lf desired, however, the cross head Ymay work on a pair of bars (10) projecting from the inner end of thc cylinder as indicated in Figure et. The rods therefore move back and forth with the pistons in a straight line and-arc prevented from revolving by the cross head. j

llach piston rod carries rollers (1l) at its inner end engaging opposite sides of a driving flange (12) secured to the shaft.

The flange is shown in Figure 1 as triangular shaped with rounded points and depressed sides, but it may assume other forms either oblong, square as shown in Figure 5, or whatever the arrangement of the cylinders, stroke, size of rollers, etc., may require in order to develop the greatest power or best results.)

lin practice two flanges are used for each piston rod, one on each side as shown in Figure 2, and the rod carries two sets of rollers bearing against the outer and inner surface of the flanges rlhe rollers are arranged to compensate for the varying angularit-y of the flange presented between them during its revolutionn lhis may be done in several ways, the one 1nd1cated being to mount the rollers on pins (13) projecting from carrier blocks (la) which are pivotally supported on the pins (15) projecting from the lpiston rod. lif desired four rollers may be mounted on each carrier as shown in Figure 7..

rFhe flange is preferably of even thickness vand the rollers on the side toward the piston are conical and the pins (13) at an angle so that they maybe adjusted to secure a perfeet fit against the Hangs.. Shims between the `hub ofthe conical roller and the carrier block will'niake this a simple matter.

My invention may be used with various types of engines but is here shown with an engine of thel T head construction having inlet and exhaust vvalves at (16) and (17) operated by cam rods (18) and (19) and which rods are operated at'the proper time by suitable cams (20) so that each cyl inder may be fired When its piston is just over every other high point onv the driving flange, theintermediate high points being of course at the end of the exhaust stroke.

It will thus be lseen that the pistons being confined to straight line movement with rollers against the flange Will force the flange and shaft to rotate, and the inner surface of the flange Will pull out the piston for the suction stroke.

The effectiveness of the engine depends on the particular form and size of the driving @langes and their relation to the pistons. If the pistons are offset with respect to the shaft as indicated in Figure it is manifest the power stroke delivered against the flange will be more effective, but on the other hand vthis Aoffsetting cannot be very much or the piston Will not rise With lthe next high part of the flange.

Instead of having the rollers (13) mounted 'on a pivoted carrier to compensate for the angularity of the flange it is possible to have the rollers rigidly spaced on the piston rod and operating against a flangeof variable thickness, as indicated at (12') vin Figure 6, to compensate for the angularity, or the rollers on one side of the flange may be yieldingly mounted in any manner to accomplish the same result.

l. An engine of the character describedl comprising a casing with "a straight shaft therein, a pair of driving flanges spacedly secured to said shaft,- a cylinder carried by the casing having a piston reciprocable lftherein, a piston rod rigidly secured to the" piston and projecting between the flanges, carriers pivotally connected to the piston rod and a plurality of oppositely disposed rollers connected to the carriers and engaging opf posite sides of both flanges substantially as described. u

2. In an engine of the character described a rotatable flange, a piston having a rod with rollers thereon opposite sides of the llange, and means for adjusting the rollers to lit closely against the flange, said means comprising a turnable adapted to bear againstangular mounting for turning the rollers rel ative to the flange whereby they may be ad justcd to andfrom the flange.
