Abstract: 101,781. Walker, A. H., (Wood, H. A. W.). Oct. 19, 1915. Printing-surfaces; stereotype.-In a machine for casting and finishing stereotype printing-plates, the plates are cast face downwards and withdrawn from the mould by a reciprocating carrier, which conveys them past saws for trimming the ends of the plates, and to a second conveyor which pushes them under mechanism for shaving the backs of the plates and then past other saws for trimming the sides of the plates. The plate P, Fig. 5, is cast face downwards and with a notch P<3> by which the plate is withdrawn from the gauges of the upper part 95 of the casting- box 95, 93 by spring-controlled hooks 177 carried by a pair of arms 175, Figs. 1 and 5, transversely adjustable on a bar 174 secured to a rack-bar 173 reciprocated by gearing from a shaft 38 driven from the main shaft 40. The stroke of the bar 173 may be varied to suit plates of different widths. The hooks 177 draw the plate past belt-driven trimming-saws 183 on to supports 180, 188, from which they are pushed in a direction perpendicular to their previous movement by pushers 201, Figs. 1 and 9, carried by a rack-bar 189 reciprocated by gearing from the shaft 40. The pushers 201 move the plate on to a support 203, and the back of the plate is then shaved by a knife 212, Fig. 8, carried by a reciprocating slide 209 driven from the shaft 38. A spring-pressed roller 214 presses on the plate in advance of the knife to prevent buckling of the plate. The shaved plate is pushed off the support 203 by pivoted fingers 218 carried by the rack-bar 189, past saws 231 for trimming and bevelling the sides of the plate, on to supports 230, 240, Fig. 10. The plate is held down on to the supports 230, 240 by guide plates 241, 242 engag ing the edges of the plate. A second set of pivoted fingers 219 carried by the rack-bar 189 pushes the finished plates from the supports 230 240 into one of a series of receptacles 255, Fig. 9 The upper ends of the fingers 218, 219 engage be tween collars 221 on a shaft 222 carried by the rack-bar 189 and adapted at the end of each platepushing stroke to engage a stop 223 to move the fingers on their pivots so as to clear the plates on their return stroke.

Title: Steering stabilizer for motor vehicles
IPC: B62D7/22
Filed: 1932-04-25
Abstract: 399,897. Hydraulic shock-absorbers. BERG, F. H., 54, Talbot Avenue, Balwyn, Victoria, Australia. April 25, 1932, No. 11866. [Class 108 (iii).] An 'hydraulic shock-absorber adapted to connect a moving member of the steering-gear of a vehicle to the axle or other stationary member is provided with means adapted to maintain the liquid pressed continuously so hard against each face of the piston or movable pressure member that play between the piston and the liquid is almost entirely eliminated. In the construction shown in Figs. 1 and 3 a cylinder 1 is pivoted at 11 to the front axle and encloses a piston 27 having a rod 4 pivoted at 22 to a clamp 15 adjustably secured to the steering track-rod 14. The cylinder is maintained full of oil under pressure by means of a spring-pressed piston 5, the back of the pistons being open to the atmosphere by a vent 7. The piston 27 is provided with a leakage bore 28 and fits closely in the central part 24 of the cylinder, but is loose when it moves beyond this part, so that shocks are only absorbed in the central position. The piston is kept coaxial with the cylinder by means of the guide afforded by a long stuffing- box 34, and its ends are tapered at 26 to prevent it from locking against the part 24. Instead of forming the cylinder with the reduced central part 24 the same effect may be obtained by providing the cylinder with grooves extending from its ends towards the centre. The cylinder may be connected to the track-rod and the piston to the axle. In the construction, shown in Fig. 6, the piston 25<1> is fixed to the track-rod 14 and the cylinder 1 is connected by a link 47 to the front axle. In this case since the piston rod 14 extends through both ends of the cylinder the volume of the latter is constant. The reduced central part of the cylinder is formed by a ring 25 expanded into intimate contact with the interior of the cylinder. The piston may have a leakage bore, as in Fig. 3, or communication between the cylinder ends may be effected by a passage 29 with an adjusting valve 30. The cylinder is kept full of oil under pressure by means either of the engine oil-pump or by a reservoir 43 having a spring- pressed piston 44, a non-return valve 42 being provided between the reservoir and the cylinder. The reservoir may be fille dthrough a non-return valve 45, by an oil gun, an air-release screw being provided on the clinder.

Abstract: 712,788. Kerbs. PRESTON, J., and SMITH, D. F. March 4, 1953 [May 10, 1952], No. 11891/52. Class 126 Separately formed channels forming spaced sheet metal guides to receive and retain tiles slid into them are secured to the top and front surfaces of a kerb body means being provided at each end of the kerb to locate the tiles endwise, one of said means being readily removable to allow the tiles to be inserted and removed. As shown the invention is applied to an extending kerb of three members 10, 11. The sheet metal tubular member 10 is provided with channel section tile holding strips 12, 13 and 16 on its top and front surfaces respectively. After the tiles have been inserted the channels at each end of the member are closed by screw fixed transverse bars 17 the space between the front and top channels on the top and front of the member respectively being filled in by an ornamental metal strip 19 which is slid into place. The end members 11 may also be formed as sheet metal tubes but as illustrated each is built up from wooden bars 23, 24, 25, covered on the inner face and base with sheet metal 26 and provided on the other two faces with tile receiving channel guides 27, 28. The tiles on the front portion of each member 11 are located endwise by screw attached wooden blocks 31 whilst for the tiles of the end portion plates detachably secured against the end of the portion are used. The junction of the two portions is filled in by a vertically extending angle section strip. After adjusting the width of the kerb each end member is locked in its adjusted position by a screw 35 passing through any one of a series of holes in the central member 10 and any one of a similar series of holes in the member 11. When applied to a rigid kerb the tiles of its front portion may be inserted and removed by making a central portion of each of the channel guides on the top front edge of the kerb and of a length greater than that of a tile readily detachable such that when the portions are removed the central tile on the front or top of the kerb may be removed laterally thus allowing other tiles to be slid along to the centre for removal.

Title: Improvements in or relating to safe-air-speed indicators for aircraft
IPC: G01P5/175
Filed: 1946-04-23
Abstract: 611,140. Aircraft safe-speed indicators. BEAMONT, W., and K.D.G. INSTRUMENTS, Ltd. April 23, 1946, No. 12237. [Class 106 (ii)] An instrument for indicating safe speeds for aircraft comprises, in combination, a device showing indicated air-speeds and a device responsive to changes in static air-pressure, the movements of the transmission means for the latter corresponding approximately to the tangent curve to a given equation, and means for indicating the output movements of the transmission means on the same scale as that employed for the air-speed device or on a scale having corresponding graduations in line with those of the air-speed device. It is shown that the safe indicated air-speed is a function of the static pressure at the altitude at which the aircraft is flying, and this can be obtained by converting the responses of a pressure gauge to satisfy the given equation. As shown, an evacuated capsule 10 responsive to static pressure operates on an attached stirrup 12 carrying a pivoted rock-shaft 13 which has secured thereto a spindle 14. The lower end of the spindle 14 abuts an adjusting-screw 15, and the upper end engages a straight edge 18 formed on one arm of a toothed sector 20 mating with a pinion 30 secured to a tubular spindle 29 carrying a pointer A. The sector 20 is pivoted at 21 between two plates 22 which are pivoted on a spindle 23, the lower plate 22 having rack teeth 25 engaging a pinion 26 on a shaft 27 which can be turned for adjustment purposes by the engagement of a screw-driver in the slot 28 in the end thereof. This adjustment may also be arranged to adjust a device for indicating Mach numbers. The screw 15 is used for zeroizing the pointer A. The response characteristic of the capsule 10 may be modified by arranging a set-screw 31 in the stirrup 12 to engage a spring blade 32, the stiffness of which is controlled by a number of adjusting screws 33 on a fixed carrier 34. The air-speed indicator comprises a second capsule 35, responsive to pressure according to the indicated air-speed, having a stirrup 36 for a rock-shaft 37 carrying an operating spindle 38. The upper end of this spindle engages a straight edge on an arm of a pivoted toothed sector 40 engaging a pinion 41 fixed to the spindle 23 which passes through the spindle 29 and carries a pointer B. The response characteristic of this second capsule is also capable of modification by a leaf spring 48 and screws 49, and the pointer B can be zeroized by a screw 51. The upper plate 22 carries a scale 45 of Mach numbers and the toothed hub 44 thereof is engaged by a toothed sector 46 secured to the shaft 27. Both pointers A, B traverse over an indicated air-speed scale (not shown) encircling the scale 45. The instrument is so adjusted that safe conditions prevail when the pointer B is reading a lower value than the pointer A.
