Definitions

  • This invention relates to means whereby a body, machine or apparatus may be supported from, and/or connected to, a .second body, machine, 'or apparatus at or by four points not necessarily in one plane in cases where these points are liable to relative movement in a direction perpendicular to the plane nearest containing the points.
  • the object of t e invention is to provide improved means fog supporting one body from, or connecting one body to, a second body by four points in'said second body in such a manner that bending or twisting stresses will not be transmitted to the first body by reason of movements or deformations of the second body.
  • the second frame may not be a plane figure according to the relativeosition of the points.
  • the second frame will be a plane figure and Wlll remain plane notwithstanding relative movement of the primary support points.
  • the second frame can therefore form the base of a body which it is desired to support free from stresses which might arise by reason of deformation of the supporting body.

  • Fi 14 is a similar view on the line XIV IV, Fig. 11, looking in the direction of the arrow.
  • FIG. 1 the diagram illustrates a link structure made u of three squares ABCD, EFGH, KL N, each formed of four straight links connected together at the 'variouspoints indicated in the diagram by flexible connections or universal joints.
  • the points E,'F, G, H are what have been hereinbefore termed the primary support points, EFGH the primary framework, KrL, M, N the secondary sup ort points and KLMN the second frame.
  • the twisting of the square ABCD is comparativel reat then the links forming the square l GH will be subjeoted to compressive stresses but the square itself will not be twisted.
  • the links EFGH are made stifi' in a direction perpendicular to the plane of thepaper, if for example they are made of plates the plane of which is perpendicular to the plane of the paper, any bending action of the links EFGH due to the compression stresses will be in the plane of the paper and the points ILL, M, N will therefore be moved inthe plane of the paper but the square KLMN will retain its plane form.
  • the links EFGH are constituted by beams which are stiff in a direction perpendicular to the plane of the paper but are torsionally flexible about a longitudinal axis
  • the square ABCD is deformed by a displacement of the sides AD and BC in the same direction perpendicular to the plane of the paper while the points E and G remain stationary which is equivalent to a bending of the square ABCD about a line joining EG
  • the links or beams forming the square EFGH will each be twisted about a longitudinal axis but the points K, L, M, N, will still remain in one plane.
  • the square ABCD which, as before stated, is assumed to be formed of links flexibly connected at their ends so as to make a readily deformable structure, corresponds to and exemplifies the se'ond or supporting body which is liable to deformation.
  • the square KLMN corresponds to the base ofthe body which is to be supported, the two bodies being connected at the points E, F, (i, H through the medium of the pri mary framework EFGH. In practice the square KLMN would generally be a frame forming part of the body to be supported or to which said body is firmly connected.
  • HK EL FM GN KE LF MG NH F igs'. 2,?) and 4 illustrate how the principles above enunciated may be applied according to the present invention for the purpose of supporting a gear case from a ships floor.
  • the floor is formed by plates 1 which constitute the tops of the tanks forming for example the double bottom of the ship and the primary framework 2, 3, 4, 5 is formed of four bea me which are firmly connected to the plates 1 at their ends 6 by means of the usual rivets or bolts for example. It will be observed that the intermediate portions of the beams are not connected to the floor andin fact are quite free of the same, as is very clearly seen in Fig.4.
  • These beams are stiff in a direction perpendicular tothe plane of the floor but under stress they will bend in a plane parallel with the floor or will twist about a longitudinal axis.
  • the mid points approximately of said beams are connected to the framework formed by the beams 7, 8, 9, 10 as shewn and it will be-clear that bending of the beams 2, 3, 4, 5 in a plane parallel with the lane of the floor 1 0r twisting of said beams, 2, 3, 4, 5 will not communicate any twist to the frame formed by the beams 7, 8, 9, 10. Consequently these beams may form the base or bed plate of,
  • a gear case such as indicated at 15 in broken lines in Fig. 2. It will be observed that the beams 7, 9, 10 are only connected at or near their ends to the seating beams 2, 3, 4, 5 and the beam 8 is connected at its ends to the beams 7 and 9, said beams being sufli ciently stiff in a vertical plane to support the weight of the gear case without bending.
  • the part indicated at 16 in the figures is a seating for the thrust block of the propeller shaft which is firmly connected to the floor plates 1 by vertical plates 17 and may be connected to the adjacent ends of the beams 2 and 3. It is shewn merely for the purpose of indicating the general position of the propellershaft and the present invention is not intended to be applied to this thrust block seating.
  • the chassis of the car is formed of seven members indicated at 18, 19, 20, 21, 22, 23, 24. These are connected together at the points 25, 26, 27, 28, 29, 30, respectively, by horizontal pivots which permit the'chassis to adapt itself to the road aridso reduce shocks on the springs.
  • the middle points of the members 18, 24, 22 and 23 respectively are connected by beams 3l, 32, 33 and 34 which support .the engine bedplate on which may also be mounted if desired the gear case framework.
  • Said lbedplate is connectetd to the beams 31 to 34 at the points 35, 36, 37, 38.
  • the car body is supported from the beams 39, 40, 41 and 42 which are connected by horizontal pivots to the members 19, 20, 21, 24 of the chassis.
  • FIG. 6 An example of a joint such as is necessary at the points 25, 27, 28 and 30 is shewn in Fig. 6 where the two frame members 19 and 20 indicated as cylindrical rods or shafts are connected at right angles through a connecting piece 43.
  • the members 19 and 20 are arranged'to both rotate and slide in If for example the angle a, shewn in the figure as very much exaggerated, from the osition P to the position P the point 5 one-the member 19 will move through a distance Q, Q which is proportional to the versed sine of the angle a and consequently the member 19 must slide in the connecting piece 43 to this amount.
  • chassis 18, 19 ⁇ 20, 21, 22, 23 corresponds to the frame ABCD of Fig. 1, the frame 34, 35, 36, 37 or 39, 40, 41, 42 to the frame EFGH and the oints 35 36, 37, 38 or the points at whic 39, 40, 41, 42 to the points K, L, M, N of Fig. 1.
  • the angle between two members of the chassis framework such as 19 and 20 for example shall be capable of Variation as viewed in plan and in this case the form of joint indicated in Figs. 7 and 8 may be adopted.
  • the connecting piece between the two members 19 and 20-for example will then be made in two parts 44 and 45, the part 19 being capable of rotation and sliding in the part 44 and the part 20 being capable of rotation'and sliding in the part '45.
  • Said parts are united through a spigot ermit of 1 and socket joint 46, 47 which angular movement on the axis and the parts 44 and 45 are prevented from moving apart by means of the brace shewn in Fig.
  • the body is connected to the frame 1 8, the two portions 49 and 50 of which are screwed into bosses 51 and. 52 on the part 45 and are connected by a cross-piece 53 through which is screwed a pin 54 adaptetd to engage with a seating 55 in the part 44.
