Definitions

  • Atafchccl- Figure 1 represents a longitudinal section of the stern ⁇ of-y a steam boat with my improvedl propeller'attached.
  • a and B are two cylinders or broadhoopsrof wrought iron supported by spiral arms orspokes which will be explained hereafter-the hoop A is attached to the axis a aga and the hoop Bto the axis b, Z2, b, which latter axis is made hollow in order to' admitthel former to pass through andwork withinit andfboth thesey axes pass directly through the center of the stern post into the body of the vessel.
  • 1,72, 3, 4, 5 and 9, 10, 11, 12, 13 are thin metallic plates attached byy rivets to thehoops A and B the face of each plate being twisted soas toform a portion of a spiral plane or thread, the exact' formof which will be determined and may beobtained'by forminga cylinder and'coiling'a thread or blade spirally around it on the principle exhibited by the diagram represented in Fig. 2 in which A AA represent a cylinder of equal diameter with the hoops A and B in Fig. 1'. a, a, a, e, a, a, a, are eight thin spiral planes or plates of thejsame width as the'plates 1, 2, 3, 4, 5 and 9, 10,11, 12 and 13 in Fig.
  • e is a brass bearing fixed in the saidgstay E which bearsoy ing carries the outer and enlarged endr of the shaft a, a, d, the other end of the shaft being carried by and working through a stuiing box F attached' to the shaftl b, b, Z ,.
  • which shaft is supported by a strong cast iron framing G andl plumber block g1 C yis astuflingbox ixed'to the stern post to prevent the water from-entering the rvessely around the shaft 5,6, 5,whichshould workfreely Athrough-thestern postand I arel two broad cog wheels working together I being about one fifth larger than H. and
  • Zand m are "cranks on the shafts L and M supportedA by cast-1 iron frames-'P P'and plumber blocks or'bearings 0.20779 p;
  • Q and R are also cranks on'the shafts-NLM and L L fixed at right angles toy the cranks-Z and m.
  • g vand r are crank pins and S a coupling link by which ⁇ they cranks Q, and It ⁇ are coupled together.
  • T is al connecting rod and Uis a couplingjlink attached to fthe' cranks Z and mi
  • This lconnecting rodl is to be connected iny the ordil'y ioo nary manner to thepiston rodforbe'amof a Y steam engine the cylinder of whichmay be placed either vertically or horizontally across the vessel.
  • Another connecting rod connected to another engine may be attached to the crank pin g in a similar manner by which a more regular power will be communicated to the cranks Yand shafts fm, M and Z L.
  • FIG. 6 is a. section showing the manner in which the requisite' contrary movement is obtained in the said application of my propeller.
  • A is a hollow stem of wrought iron, to which are welded collars Z OZ and broad flat branches or arma a.
  • B is an axle or shaft of steel F ig.3 represents an end view of the.
  • Gr, H are two thin broad'hoops of wrought iron, G being firmly fixed on the axle B and II fixed on the hollow axle C.
  • Each hoop is provided with a series of spiral planes as described in the foregoing description of my improved propeller applicable to steam navigation.
  • g g and 71. t are .the spiral spokes also before describedV but which spokes in addition to their twisting or spiral .form are here curved or bent outward in ⁇ order to give roomfor the flat arms t a of the hollow stem.
  • a drum P P P of slight metal divided into three parts and pointed toward the ends ismade to inclose all the gear work ⁇ under water, the central part of which drum, being fixed to the arms a a and the pointed ends or caps fixed to the spokes of the propellers slits being made Afor that purpose and a space of about one eighth of an inch leftf between the three parts in order to admit of a free and contrary movement of the propellers.
  • K is a bracket of iron (better seen at K K), it is firmly xed to the stern for the purpose of carrying the propeller, by means of the hollow stem A and its collars d cZ the hollow stem being kept in its place by the key Ze which is securedto the bracket K by a slight chain.
  • L is a stay ofwrought iron, to keep the hollow stem A firmly in an upright position; and to receive and communicate the force of the propellers for which purpose it is ⁇ attached to the stern post by hinges on each side of the rudder; its form will be better seen at L L, the rudder being made to work between Z, Z andthe fork lVI fitted to receive the hollow stem A, which iskept in by a key m this being secured to the stay by a slight chain as shown in the drawing.
