Title: Improvements in apparatus for tipping wagons
IPC: B65G67/00
Filed: 1926-07-07
Abstract: 275,009. Wellman Smith Owen Engineering Corporation, Ltd., and Pattinson, T. J. July 7, 1926. Tipping-apparatus. - A tipping- cradle 1 mounted in a frame structure A, B, C is supported by ropes 4 and 13 which are wound oppositely on a drum 5 so that when the ropes 13 are wound in for tipping the cradle, the ropes 4 are paid out and the cradle lowered, and little power is required for winding the drum. As shown, the cradle tips about pivots 2 which are supported in bights of the ropes 4 and move in vertical guides. The wagon rests upon a platform 6 movable laterally on the cradle against the action of a spring 8. In the normal position, the platform is held to the right by a stop 11 with the spring in compression. As the cradle is tilted free of the stop 11, the platform moves to the left, and the wagon comes against the side-support 9. On further movement, the pivots 2 descend in their guides, and the top of the wagon engages two beams 17 mounted on cross-bars 16 which are suspended from ropes 18 carrying balance weights 19. The bars 16 are connected with the pivots 2 by links 20 so that the lower clamping beam is swung out to meet the wagon top as the pivots 2 descend.

Abstract: 570,547. Magnetic compasses. LESTER, R.E. Oct. 18, 1943, No. 17100. [Class 97 (ii)] In order to correct for variation and deviation, a magnetic compass, mounted on an aeroplane is provided with a compass scale of elastic or flexible material which is capable of expansion and contraction and means are provided at predetermined points for so expanding and contracting it. A fixed flange 5 having marked thereon the eight cardinal points is provided and around this is mounted in a slightly stretched state an elastic annular compass scale 6 seated upon, and operatively connected with, eight supports 7 arranged to be circumferentially adjusted by screws 9 to expand or contract the compass scale 6 at those parts. A support 13 having a scale 14 is also provided to carry a pointer 12 adjustable by a screw 16 and to act as a variable lubber line. To set the scale, the variation of the district is set on the auxiliary scale 14 by moving the pointer. The aeroplane is headed to true north and the rotating ring is turned to bring the parallel wires 18 parallel to the needle 1 and the support 7 is adjusted to bring the zero of the scale 6 immediately under the pointer 12. The aeroplane is then headed successively to the other cardinal points and the process repeated so that the compass scale is corrected at each of these cardinal points.

Title: Improvements relating to Blast Furnace Skips.
IPC: C21B7/18
Filed: 1917-11-24
Abstract: 111,674. Soc. J. Munier et Cie. Nov. 25, 1916, [Convention date]. Load, engaging, releasing, and depositing. - In a blastfurnace charging-apparatus in which the suspension rod of the skip is engaged and held by a supporting-hook on the hoist mechanism, the hook continues to descend a short distance after the skip has come to rest at the ground level, and the arrest of this movement causes the hook to open and free the skip. The hook is formed of two parts 18, 19 which, when closed together round the mushroom head 22 of the skip suspension rod, form a cylindrical body slightly less in diameter than a tube 4 carrying the skip cover 1. The parts 18, 19 are formed externally with a projecting ring 31 to engage a corresponding undercut groove in the head 22, and are pivoted at 20 to the rod 7 suspended from the pulley block 43. The rod 7 is guided within a tube 10 having slots 16, 14 for allowing the movement of a cross piece 17 connected by rods 15, 16 to the two parts of the hook. During the lowering the cover 1 is arrested and held by stops 28 in the path of projections 41, while the skip descends further until the hook is clear of the lower end of the tube 14. In this position the skip is brought to rest, and further lowering of the hoist pulley brings the cross-piece 17 into contact with the upper end of the tube 4 and allows the rod 7 to force open the two parts of the hook as shown in Fig. 3. In a modification, Fig. 18, the cover 1 is suspended by a chain 63 and a weighted cable 59 from a winding drum 58 geared to the main hoist drum 54. The drum 58 is of two diameters or is cored for part of its length, so that, during the lowering of the skip, the cover is gradually left behind, the cable being of such length that it is fully paid out when the skip comes to rest. The further lowering of the pulley block 43 for opening the two parts of the hook is allowed far by a cutaway portion u, x, Fig. 16, in one end face of the drum 58, which permits the drum to turn through the angle s, t without movement of the cable 59.

Title: Improvements in or relating to steering arrangements for motor or like vehicles
IPC: B62D3/02
Filed: 1929-06-06
Abstract: 334,931. Mackenzie, D. G. June 6, 1929. Non-reactive steering - mechanism. - Non- reactive steering-mechanism comprises two projecting members adapted to be rotated about a common axis by the steering handle and to engage opposite sides of a block so that the road wheels are steered in one direction by one projecting member and in the other direction by the other member. According to another feature of the invention each of two projecting members is adapted by sliding or rolling over a surface or surfaces of a wheel-turning member to cause the wheels to turn in the direction required. while auxiliary surfaces are provided on the wheelturning member to absorb road shocks independent of the first-mentioned surfaces when the projecting members are in the mid position. According to another feature two projecting members rotating about a common axis cooperate with a relatively-movable part having slots in which one or the other of said projecting members engages according to the, direction of movement but in which the projections do not engage simultaneously. In the construction shown in Figs. 1 and 2 the steering shaft S.H. drives a shaft S.H.S. through bevel gear and the latter shaft carries rollers R<1>, R<2> adapted to engage a central block B and adjustable blocks B<1>, B<2> carried by a rocker arm F pivoted at P and connected to the stub axles. In the mid nosition shown the centres of the rollers are in line with the inner edge of block B, and the three blocks form in effect two grooves G<1>, G<2> adapted to be engaged respectively by the rollers R<1>, R<2>, but. as one roller moves into its groove the other roller moves out of the other groove. Thus the gear is self-centring, while in the mid position the outer blocks B<1>, B<2> absorb any road shocks. The grooves may be parallel as shown, or the faces of the blocks may be so shaped as to produce any desired ratio of the gearing. In a modification the rollers are conical and are carried by the steering shaft so as to engage in two grooves in a member forming the rocker arm, the shaft of the latter being in this case at right angles to the steering shaft.

Title: Multiunit printing presses
IPC: B41F33/08
Filed: 1966-04-22
Abstract: 1,117,973. Multi-colour rotary offset presses. HARRIS-INTERTYPE CORP. 22 April, 1966 [7 June, 1965], No. 17713/66. Heading B6C. A multi-colour sheet fed rotary offset press comprises a plurality of printing units the latter being grouped in pairs, each unit having its offset cylinder movable from the printing position. Manually operable means by which any of the offset cylinders may be thrown-off are located at the delivery table of the press. Using said controls a sheet fed through the press may be printed in one or any combination of colours. The apparatus shown comprises a four-colour lithographic press 10 having four successive printing units 11-14 each including plate, blanket and impression cylinders 15, 16, 17 and inking and damping mechanism 18, 19. Each sheet to be printed is gripped by fingers on the impression cylinder 17, printed in one colour in the associated unit and passed to the next unit by either a transfer cylinder 22 or a chain transfer mechanism 23. The printed sheets are discharged at a delivery table 29. Proof printing.-The press may be used for proof printing, i.e. printing sheets with only the colour and image of any one unit. It may also be used to print combinations of the colours to be printed in these units, e.g. the combination of colours printed in units 13, 14. It may further be used to print all the combinations of colours which include one unit and then print all the combinations which include the next unit. For example, first printing in units 11, 12, then in 11, 13, then 11, 14, then in 11, 12, 13 and so on. The actuating mechanism for the proof printing also ensures that any one blanket cylinder is not "thrown-off" for too long a period causing an excessive build-up of ink and dampening solution. Tripping arrangements.-The blanket cylinders 16 of the units 11, 12, 13, 14 are mounted in eccentric bearings and are actuated by lever and linkage means from cam arrangements for " throwing-on " and "throwing-off" " relative to the work flow. Each pair of blanket cylinders associated with a unit pair 11, 12 or 13, 14 are mechanically linked to effect sequential " throwoff " and " throw-on ". Air motors are employed to selectively move the blanket cylinders for proofing purposes. A sheet detector is used in connection with the sheet feeding mechanism to the first unit 11, the absence of a copy sheet causing automatic sequential " throw-off" of the blanket cylinders of the units 11 and 12. A separate photo-cell is used to detect the absence of sheet feed to the unit 13, such detection resulting in sequential " throw-off of the blanket cylinders of the units 13 and 14.

Abstract: 769.890. Pliers. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. June 24, 1955 [June 29, 1954], No. 18334/55. Class 61. Pliers for forming an open or closed loop in wire or strip material comprise a pin 13 shaped to form the inner surface of the loop and two jaws 1, 2 operated by handles 4, 5, with recesses 6 together corresponding to the outer surface of the loop, the movement of the jaws relatively to' each other and to the pin being such that when the material is inserted in the jaws and the handles closed towards each other; the material is first bent by relative movement of the pin and then wrapped round the pin by closure of the jaws to form the loop. The jaw 1, which is longer than the jaw 2, has an aperture 7 above the recess 6. A groove 8 extends from the recess to the tip of the jaw. A guide groove 9 is formed in the tip of the shorter jaw 2, similar in shape to the groove 8 and. complementary to the aperture 7 to embrace the wire when the pliers are closed. The pin 13 is mounted on a central slide member 10 provided with a slot 11 which fits round the pivot pin 3. Two pairs of links 15, 16 are each pivoted to the slide 10 and to a handle so that the slide moves. in a straight line between the handles. If the loop is to be formed at the end of the wire an end 17 is led into the aperture 7 whilst passing under the pin 13. When the pliers are closed the pin 13 pushes the wire downwards (Fig. 5) whilst partiallydeforming it, so that the end disengages from the aperture 7. Upon further movement of the jaws, the pin 13 leads the deformed wire between the recesses 6 to form the loop. The pin 13 is tapered so. that the loop may be readily removed. When strip material is used the grooves 8, 9 have the shape of the material and the aperture 7 is a slot. The pin 13 may have a circular, elliptical, rectangular or other shape, the recesses 6 having a complementary shape. When it is desired to form loops in the length of the material the aperture 7 is dispensed with and the two jaws have the same height. To form a loop out of line with the wire the pin 13 is set to one side of the jaw, the jaw to which it is nearer having a recess corresponding to more than half the loop.

Abstract: 179,098. Withers, J. S., (S. R. Mfg. Co.). July 6, 1921. Damping materials in long lengths.-Apparatus for moistening adhesive tape in which delivering and damping rollers are used is fitted with means for actuating the rollers whereby the moistening-roller is rotated before the delivery roller, thus preventing the forward end of the tape from remaining unmoistened. The moistening-roller 20, Fig. 2, works in a bath of water 18. Spring-pressed rollers 15, 16 bear on the tape 8 and press it upon the delivery roller 9. The rollers 9, 20 are actuated by rack-andpinion mechanism, Fig. 3. The rack is moved to and fro by a pin 34 on a pivoted handle. The rack teeth 31 engage the pinion 29 before the teeth 30 engage the pinion 28, hence the roller 20 carries moisture to the tape just before the latter is moved forward. On the return travel, the rack is held out of engagement with the pinions by a spring 36.
