摘要： 519,267. Thrust bearings. SMITH, J. W. Oct. 11, 1938; No. 29450. [Class 12 (i)] [Also in Group XXXIII] A screw propeller blade having a shank of tubular form is flanged externally and said flange has a plane surface and also a bevelled surface whereby it may be used for variable or fixed pitch mounting. The hollow root 7 is provided with a flange having a plane surface 11 adapted to carry a roller thrust bearing for action with the flange 3, 3A on a two-part hub when mounted so as to be adjustable for pitch. The thrust bearing comprises a locking ring 12 and oil seal ring 13, a bearing ring 14, a roller retainer 15, a locking ring 16, a bearing ring 17 and a locking ring 18. When the blade is fixedly mounted in a hub the bevelled portion 22A and the flat portion 11 of the flange are held directly between corresponding surfaces upon the two-part hub. Reference has been directed by the Comptroller to Specifications 293;307, [Class 114], 372,524, 380;812 and 487,084, [all in Group XXXIII].

摘要： 519,261. Screw propellers. SMITH, J. W. Oct. 10, 1938, No. 29334. [Class 114] Mechanism for varying the pitch of the blades of screw propellers comprises an annular hydraulic piston co-axial with the propeller axis and restrained by a spring which is coupled to the blades by an axially movable rod having a yoke and bush thereon adapted to co-operate with a curved channel member secured to the base of each blade. In an annular cylinder 22 there is provided a piston member 32 which contacts with rods 30A, 30B, 30C secured to a yoke member 34 which is under spring restraint 38. The yoke member has projections 42C which carry shoes mounted on an eccentric 40 and which fit into a curved groove 43 which is secured to the ring 44 on the root of the propeller blade. Movement of the apparatus in one direction is limited by a stop 82 and in the other direction by a stop 83 on the rods 30A, 30B, 30C which under normal pitch adjustment contacts with an interrupted ring 60. In order to permit of full feathering, the ring 60 is rotated by the inclined end of a rod 61 the other end of which is moved by rotating a cam ring 63, whereby the stop 83 is clear of the abutments on ring 60 and can move further to the right.

摘要： 460,237. Making screw propellers. SMITH, J. W. July 24, 1935, No. 21072. [Classes 83 (ii) and 83 (iv)] Rolling forging.-A rolled or extruded billet 10, Fig. 1A or 1D, with longitudinal flowlines is rolled out to make a propeller blade between a pair of die rolls or between a die roll 14 and platen 15 so that the metal flows along the curved lines of the finished blade from root to tip. The roll 14 is lowered and pressed in to the work by cam 50 on rotating shaft 70 bearing against the cam roller 49 to rock the shaft 53 which pulls down the link 52 and so straightens the pairs of toggles 30a, 31b, carrying the roll. A quick return oscillating beam 56 then reciprocates the platen 15 through an adjustable link 57 to roll out the work. The platen 15 is mounted on a cradle 20, Fig. 7 with an arcuate base so that it can tilt with the roll 14 to give the required twist to the blade. The roll is rotated from the reciprocation of the platen through a rack 59, Fig. 4 secured to the casing rotating the pinion 64, Fig. 7 on the roll shaft. The roll 14 is lowered further for the next pass by altering the initial angle of the toggles as follows : pin 48b is moved by hand or automatically from hook 47a to hook 47b by a rack thereby moving crank-pin 45 to alter the position of link 44 which pulls on the links 40 of the toggles to alter their angular setting from 53a to 53b. An adjusting screw 45b sets the throw of the crank-pin for the required amount of reduction of the pass. If the lever 67 is not moved the pin 48b remains in position and so the original pass remains. The machine is started by hand operated clutch 78 and performs the sequence of lowering the roll, then moving the platen to the right, lifting the roll and returning the platen. The roll and platen may be heated by automatically controlled electric elements 4 and 5 respectively, e.g. for working on aluminium or magnesium alloys. A pair of oscillating or rotating rolls may be used instead of a roll and platen.

摘要： 261,556. Mitchell, A., and Smith, J. W. Dec. 10, 1925. Stays for windows pivotally mounted about the lower edge comprise an attachment plate P which is secured to the side frame and carries the stay arm P and a pivoted stop P therefor, and a guide member A secured to the window, the plate A having means such as a pin A which, as the window closes, disengages the stop from the end of the stay to cause the stay-arm to hang vertically alongside the window frame. The lower edge of the stay is notched at P for engagement with the edge P of a recess in the member A to secure the window in an adjusted position. The stay-arm is held at an angle to the window frame by the pivoted stop-piece P , as shown in Fig. 5, and the stay is lifted by hand to secure a fresh engagement of one of its notches with the member A. When the window is moved to its closed position, the pin A pushes aside the stop member and allows the stay to fall into its vertical position. The pivoted member B is adapted to engage over the stay to secure it when the window is in the open or closed position. A hinged beading may be provided to close the gap between the window and its frame.

摘要： 260,874. Atkinson, J. B., Smith, J. W., and Mitchell, A. May 7, 1926. Fanlights; reversible windows.-The pivoting arrangements for window sashes described in Specification 254,140 are replaced by two members each having a convex quadrant face 9 fixed to the lower corners of the sash and two members 3 each having a corresponding concave face 5 fixed to the frame. The members 3 are provided with stops 6 and 7 for the vertical and horizontal positions of the sash and projections 8 on the members 3 engage recesses 10 on the sash members to prevent withdrawal in the horizontal position. The sash may be removed from the frame when tilted. The sash and sill, and if desired the meeting rails, are correspondingly stepped and inclined to exclude weather.

摘要： 203,491. Smith, J. W. Aug. 9, 1922. Back-pedalling brake arrangements. - In brakes of the type in which a flaxible brake band 21 is tightened on the drum of the free wheel clutch by means of one or more projections on the chain wheel engaging a pawl or tooth on the band, the brake band 21 is secured at one end to the cycle frame by an overhanging pin 20 on a lug 19 on the bottom fork 11, the other end of the band having a slidable fixing formed by looping the band (or providing it with a slotted tag) to engage an overhung pin 23 on the rear fork 10. The tooth 25 is rigidly fixed to the band between its ends, the flexibility of which allows the projections on the chain wheel to ride over the tooth in the forward direction. A spring 29 may assist retraction of the band from the drum.

摘要： 151,320. Withers, J. S., (Smith, J. W.). June 13, 1919. Regulating; valves; valve-gear.-Radial-cylinder and other engines for use more particularly upon aircraft are charged with combustible mixture by a centrifugal fan actuated by an exhaustdriven turbine, the quantity of charge retained in the cylinder for compression being varied in accordance with the atmospheric conditions. Fig. 1 shows one of the cylinders of a radial-cylinder engine having a charging fan 19 actuated by a turbine wheel 55, to the casing of which exhaust gases are supplied through a pipe 51 opening into the cylinder through a terminal port 50. Combustible mixture is supplied to the fan from a carburettor 6 having in its air inlet 8 a throttle valve controlled by a barometric device 10. The turbine and compressor rotate in an opposite direction to the crank shaft. Co-axial admission and exhaust valves 28, 26 respectively are located in the cylinder head, the valves being actuated by cams mounted upon an axially-adjustable sleeve 35 which is controlled by hand to vary the time of closing of the inlet valve, through which a portion of the charge is rejected to the pump delivery pipe 23 during the compression strode. The cam sleeve 35 is driven through a train of wheels which is moved axially with the cams.
