Definitions

  • My invention consists of a combination and arrangement of parts, which has the effect of producing a very compact and small engine of light weight for the power pro.
  • My invention not only produces a small, compact and light engine for the power produced, but also a form of engine that is l0 particularly adapted for certain purposes Where space is restricted.
  • My invention has to do with that class of internal combustion engines which employs opposed pistons, or two pistons reciprocating in opposite directions in one open ended cylinder, and is particularly concerned with the manner of transmitting the movement ofthe opposed pistons to the revolving shaft of the engine.
  • My invention is not concerned with the manner of introducing the fuel into the cylinder, or with the ignition of the fuel, and it is applicable to either the fuel injection, or Diesel type of engine, or to the gas, or carburetting engine.
  • my invention is embodied in an engine having a main shaft with two inclined crank pins whose axes are inclined at an angle to, and intersect the main axis of the shaft.
  • a Wabbling member is loosely or revolvably mounted on each of these inclined crank pins.
  • a number (preferably four) of open ended cylinder-s Arranged parallel to and surroundinclined crank pins are a number (preferably four) of open ended cylinder-s, each cylinder having two pistons reciprocating in opposite directions within it. Suitable connections between each of the said pistons and one of the said wabblin'g members serves ⁇ to complete the transmission of movement of the pistons to the shaft.
  • One of the important features of mylinvention lies in the arrangement of parts whereby the reaction of the thrust of the two pistons in opposite directions, in any one of the cylinders, is taken by two thrust bearings on the main shaft, so that the effect of the two opposed thrusts is to produce a longitudinal tension in the shaft.
  • the frame of the engine is Arelieved in this manner of the necessity of reacting against these thrusts.
  • FIG. l shows a longitudinal section of a two cylinder engine, embodying my invention, the section being taken in the plane of the axes of the cylinders and shaft.
  • this figure is made to some extent diagrammatical.
  • Fig. 2 is a partial longitudinal view of a a four cylinder engine, taken ⁇ in the plane of two of the cylinders and the shaft, and silovting only one half of the cylinders and s
  • Fig. 3 is a cross sectional View, taken in a plane perpendicular to the axis of theshaft of a four cylinder engine, looking towards the open ends of the cylinders, or on line 3/-11/ in Fig. 2.
  • Fig. 4 is an end view of one of the parts designated as Wabbling knuckles taken in a pla-ne perpendicular to the axis of the knuckle, or to the aXis of the crank pin.
  • Fig. 5 is al longitudinal plan view, with the upper part of the cylinder holding body removed, and is intended particularly to show the arrangements provided for operating the fuelA valves, or for operating starting valves, or other devices which require cyclic operation.
  • the main frame (l) carries a cylinder holding body (2) which is preferably made in two parts. In this ca-se there is one cylinder vin each part, one above and one below and both parallel to the shaft.
  • the shaft (3) passes through the cylinder holding body along the junction or joint between the upper and lower parts.
  • the cylinders are bored directly out of the cylinder holding body (2), and that part might properly be said to constitute the cylinders, but I prefer to refer to it as a cylinder holding body, as it may be advantageous to form the cylinders themselves of separate tubular parts, which may be inserted in and held in place by this cylinder holding body. It will be understood that in this description, and in the claims which follow, this part, referred to as a cylinder holding body, may constitu'te the cylinders themselves, or a part in which the cylinders proper are inserted and held. 4
  • the shaft (3) is carried in bearings (4) in the cylinder holding body, and in bearings (5) in the main frame (1).
  • Those portions of the shaft between the end bearings (5) and the cylinder holding body comprise cranked portions, or crankpins (6), one at each end of the shaft.
  • These cranked portions of the shaft, or crank pins have their axes inclined at an angle to the main axis of the shaft, and are preferably formed in the same lane.
  • Wabblingknuckle is preferably made in halves joined in a suitable manner, so that they can be put in place to embrace and ride upon the crank pins (6) on which they have a suitable running fit.
  • the blocks (8) can be mounted on the cylindrical pins (9), but if theaxes of the pins (9) do not intersect the points (11) then a universal movement Will have to be provided for between the blocks (8) and their points of attachment to the wabblin knuckles (7).
  • the pistons at one end of the engine are all connected to the Wabbling knuckle at thatend of the shaft by means of the connecting rods (16). These rods have connec- .tion to the pistons through ball and socket joints, or some equivalent arrangement, permitting universal movement..- In Fig. 1,
  • the ball is formed on the end of the rod
  • the thrust of the pistons through their connections against the Wabbling knuckles, is eounteracted by the thrust bearings or collars (18) Whichare formed, or mounted rigidly on the crank pins, or cranked portions of the shaft.
  • the pressure of the two Wabbling knuckles against the thrust bearings on the shaft constitutes two e ual and op osed forces which balance eac other, an produce a tension in the center portion of the shaft.
  • the thrust bearings on the cranked portion of the shaft shown in Fig. 1 are there shown in the elementary form of plain faced collars 18 against which the inside face of the Wabbling knuckles 7 directly bear. This serves to illustrate in the most simple form the function of the bearing and thecooperawhile in Fig. 2 the socket is shown formed i tion of parts. In a practical working design however, it is very essential that a form of thrust bearing be provided, that will continuously sustain the bearing pressures exerted by the pistons against the wabbling knuckle without undue heating and without failure.,
  • the pistons In an engine operating on the two-stroke cycle for which my invention is primarily intended, the pistons always exert an outward force, in the form here described, a continuous force against the wabbling knuckles, and this forcefrom the combined action of four pistons as illustrated in Figs. 2 and 3, is very great, and has to be counteracted by the thrust bearing and so transmitted to the shaft.
  • ⁇ is therefore largely dependent upon the use of a form of thrust bearing capable of continuously holding up under this very severe service. I do not consider in large sizes, any form of ball or roller thrust bearing suitable, while the plain collar type of thrust bearing in this application would be entirely unsuitable.
  • a thrust bearing comprising a number of separate, pivotailly or universally supported shoes, which together take the end or axial thrust of the wabbling knuckle and transmit it to thethrust collar formed on or secured to the crank pin.
  • Fig. 2 I have shown in elementary form such a type of thrust'bearing.
  • equalizing devices such as are commonly embodied in bearings of this type, whereby the total pressure on the bearing is cqualized among the separate shoes employed, even though the parts, constituted in this instance by the knuckle and thrust collar, may not runA exactly true or coaxially. In actual practice such equalizing devices would be provided.
  • This form of bearing not only shows small frictional losses, and can continuously function under the heavy loads which this application imposes, but also permits of the use of a split thrust collar 18 or one made of halves and clamped around Vits seating on the shaft or crank pin, which is the intended manner of holding the collar 18, as shown,
  • the axes of the crank pins (6), or the axes of the wabbling knuckles intersect the main axis of the shaft, as indicated in the drawings, Figs. 1, 5 and (i, and also that the axes of the pins (9) carrying the sliding blocks (8) intersect the axis of the-shaft at the saine point, as indi; cated in Fig. 1, but this exact intersection of these axes is not absolutely essential, as a limited deviation from exact intersection is allowable, if the attachment of the sliding blocks (8) to the wabbling knuckles allow for universal movement.
  • the points of connection of the connecting rods (16) to the knuckles (7). all lie in a plane perpendiculaito the axis of the crank pin and passing through the point; of intersection of the axis of the crank pinwith the axis of the shaft, as shown in Fig. 1.
  • a diagram of forces will disclose, that ⁇ for a given length of crank pin, or for a given llo of the cylinder, the less will be the maximum and the average pressures on these bearings of the wabbling member on the pin.
  • crank pins are long and the point ofintersection l1 with the 'shaft axis is toward their inner ends, so placing the outer bearing of the wabbling knuckle on the pin, a considerable distance from the shaft axis, and close to the cylinder axis, while the inner bearing is close to, or as shown in the drawings, almost centers on themain shaft axis.
  • crank pins and shaft may be so'designed, for example, that the entire crank pin may lie to one side of the shaft axis, and the intersection of the axes of the pin and shaft would then come on a continuation or extension of the crank pin axis inwardly beyond the inner bearing on the pin.
  • Such proportions and arrangement would, of course, increase the throw of the outer end of the cra-nk pin, and with the same length of pin as shown in Fig. 2, for example, would have the effect of reducing the bearing pressures on the pin below thatwhich results in the proportions and arrangement shown in Fig. 2.
  • this tension is not transmitted through any offset crank arm, required thereb 1 to sustain bending stress, but in a very irect line, as shown in Fig. l through the centerportion of -theshaft and the two'l massive wedge shaped blocks connecting the center portion of the shaft to the two crank pins. AThis results in the practical ellnination of bending stress in theshaft due to this tension.
  • vIt is very desirable in an engine of this type that the cylinders be placed as closely to the shaft as possible. 'This reirders the engine compact, light, and economical of construction, and. for a given length of stroke, lessens, the bending moment on the shaft due to the thrust of the pistons.
  • crank pin be so placed that the point 11 of intersection of its axis with that of the shaft is closer to its inner end than to its outer end, as shown in Fig. 2.
  • shaft I provide by which all the Aconditions and requirements above listed are properly met, results in an unbalanced crank pin,or a considerable revolving mass centering at the outer end of the crank pin, and including a portion of the wabbling knuckle, a portion of the crank pin and a portion of the outer crank arm.
  • This'revolving mass can be largely balanced by a counterweiglit 33, attached to an arm extending diametrically opposite to the outer Vcrank arm.
  • the oil being supplied in sufficient quantity and allowed to leak out through the end bearings and through other passages if necessary, in order to maintain such a circulation.
  • cylinders Any number of cylinders may be employed in an engine of this design that may be found convenient.
  • Four cylinders have been found to constitute a practical design, and in Fig. 3 I show a cross section showing the arrangement of four cylinders.
  • two cylinders are formed in the upper half, and two cylinders in the lower half of the cylinder holding body (2), and bearings for the shaft are formed between the two halves.
  • the lower half of the cylinder holding body rests on the base plate (25); and side plates (26), are provided,
  • the end bearing supports are vmade integrally with the base plate 1, but in practical construction, par
  • the guides 10, for the sliding block (8) are attached to the base plate (25), and are. centered on a plane passin between the lower cylinders.
  • I show an end view ofthe wabbling knuckle (7), used for a four cylinder engine, showingA the four sockets (28) for the reception of the ball ends of the-connecting rods (16), and also showing the sliding block (8), mounted on the pin y,(9), at the bottom.
  • the wabbling knuckle is made in two halves, united by a flanged joint and bolts.
  • valve gear vshafts (29), shown in Fig. 5, which reCeive motion from the main shaft (3) through the gears (30).
  • These shafts have a bearing in the end bearings (27), and lie arallel to the niain shaft (3). They pass t rough one end of the cylinder holding body (2), as shown in Fig. 5, and also in Fig. 3, and reach to 'the vicinity of the center of the cylinders.
  • valve ear shafts In the case of the four cylinder design two of such valve ear shafts are provided, one on each side of the engine, each shaft serving to operate the gear connected with the two cylinders on its side of the engine. 'lhcy are suitably supported in bearings where necessary, as in the bearings (31) in Fig. 5, and can be provided with cams (32), or other /devices for operating the valves, etc.
  • the cylinders may be set with their axes not exactly parallel to the axis of the shaft, within certain restricted limits, without materially affecting the operation desired. Any such, limited deviation cons exact parallelism between the axes ofthe cylinders and that of the shaft, does not affect the essence of my invention, and is intended to be allowed for and covered in the claims which follow, by the expression substantially parallel.
  • this exact arrangement is not essential, but, if desired, the two cranked portions of the shaft may lie in different planes, separated by a small and limited angle, so that one of each pair of co-operating pistons may have a lead over the other piston.
  • This arrangement may, if desired, be utilized to modify the relative timing of the opening and closing of the exhaust and inlet ports in any one cylinder.
