Title: Improvements in or relating to apparatus for pushing workpieces such as slabs and the like into and out of operating machinery
IPC: B23D15/00
Filed: 1936-10-16
Abstract: 461,420. Roller - way conveyers. UNITED ENGINEERING & FOUNDRY CO. Oct. 16, 1936, No. 28163. Convention date, Feb. 3. [Class 78 (i)] [Also in Group XXII] A slab or workpiece is pushed from a roller delivery table 2 into or out of a machine such as a rolling mill, or a shears 3, &c. by means of one or a pair of reciprocable pushers 29 contained within and adjustable sideways with the side guides 4 of the roller table. The side guides 4 are moved towards or from each other by a right- and left-hand screw 12 driven by a motor. The pushers 29 are moved forward and retracted each by an hydraulic cylinder 14 sliding over a fixed piston when fluid pressure is directed thereto by a two-way valve. The pushers are constrained to act in unison by racks 37 on their underside gearing with pinion 38 on a common shaft. The pusher nose 29 can be tilted up as shown dotted to clear work moved on by the roller table. The reaction thrust of the pusher and its encasing side guide 4 is stopped by a cross-piece 34 against which the lugs 6 of the guide abut. When used with a shears 3, the pushers 29 may act as gauging stops which periodically hold the work stationary while it is being sheared, the pusher 29 being set where wanted by the measuring marks 51 to gauge the length to be sheared off.

Filed: 1949-11-04
Abstract: 671,447. Making posts. PFISTERSHAMMER, J. Nov. 4, 1949, No. 28310/49. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 11, 1950.] Classes 83 (ii) and 83 (iv). [Also in Group X] A pole which may be used as a lamp support or for electric transmission lines, consists of a number of telescopic tapering tubes with tongues punched along the longitudinal edges of the two curved half-sections of which each tube is composed so that the tongues in one section enter the slots left by the tongues in the other. As shown, the large halves a of the tube are made by dividing a rectangular steel plate into halves a1, a2 by an oblique cut. Tongues z are then punched along the longitudinal edges of the sections a1, a2 which are rolled into semicircular or semi-elliptical form with the tongues pointing inwards. The halves b of the tube are made by similarly cutting a narrower rectangle but the tongues after rolling face outwards. On assembly the tongues along the longitudinal edges of the " b " sections engage in slots in the " a " sections and vice versa. The tongues are then riveted into the slots under pressure. The section of the pole is shown in Fig. 12. When an upper section is dropped over a lower to extend the tube the edges of the " b " section of the upper tube engage the " a " edges of the lower preventing relative rotation. Double and single cross-arms are shown which are formed of sheet metal which is fastened to collars by the tongue and groove method described above. Multiple rows of tongues may be used. In the case of the single cross-arm, only one collar is necessary, the other half being formed by the arm itself. The joints may be sealed and protected against corrosion by galvanizing, spraying on molten zinc, molten aluminium, or by brazing or soft soldering methods and a binding agent in wire or strip form may be inserted in the joint to prevent its loosening. The binding agent may be in the form of a solder which flows under resistance heating or the heat of the pressure applied to the seam for joining it may be utilized.

Filed: 1951-12-03
Abstract: 701,068. Aircraft undercarriages. GOODYEAR AIRCRAFT CORPORATION. Dec. 3, 1951 [Aug. 17, 1951], No. 28310/51. Class 4 A casterable aircraft landing wheel is provided with a centering cam and followers and also has associated therewith a friction brake, the arrangement being such that with the wheel in its neutral position the load thereon rests on the brake and that when a predetermined side load is imposed upon the wheel the brake yields to permit the wheel to caster whereupon the load is transferred to the cam and followers. The axle 1 rotatably and slidably supports king pin 2 suitably inclined to ensure castering movement of the wheel 9, which is mounted in bearings 8 supported on a hub 4 to which the king pin 2 is secured by a pin 3. The outer extremity of the axle 1 carries a friction pad 28 spring loaded into contact with an arcuate plate 30 to damp shimmying movement of the wheel. The portion of the axle surrounding the pin 2 is formed with a cylindrical part 14 surrounded by a flanged .collar 22 slidable on the part 14 but keyed thereto and a plurality of alternate steel and brass discs 16 are clamped between the end of the part 14 and the collar 22 by a spring 26 and the weight of the aircraft acting on the axle 1, when grounded. A cam 10 is mounted on the lower part of the hub 4 and co-operating cam followers 11 are secured to the axle 1, a suitable notch being formed in the cam 10 so that when the wheel is truly fore and aft the cam and the followers are spaced apart so that the brake 16 holds the wheel in that position. If aside load is imposed on the wheel, as during a cross wind landing, the resistance of the brake will be overcome and the wheel will caster with the followers 11 riding up the cam 10, thus separating the discs 16.

Abstract: 693,988. Roller-mills. MIAG VERTRIEBSGES. Nov. 29, 1950 FNov. 30, 1949], No. 29165/50. Class 59 [Also in Group XXIX] A roller-mill, has a servomotor controlled by a feeler 13 in the storage chamber for the material to be, ground, the servometer acting positively to couple and uncouple the drive to the feed rollers, bring together and separate the grinding rollers and actuate the feed gate. The servomotor is connected to the feeler 13 by a cranked lever 9 supported by a spring 20, a link 10 and a cranked lever 12 and comprises 'a valve-carrying piston 2 which controls the supply of pressure-fluid from a pump 21 to a ram 17 for actuating the grinding rollers and to a ram 14 for engaging the drive to the feed rollers. A valve 3 in the bore 4 of the piston 2 engages the lever 9 and is supported by a spring 7 bearing on the end 6 of the piston connected to a regulating lever for the feed gate. As the level of material to be ground rises, the lever system from the feeler 13 displaces the valve 3, against the influence of the spring 7, from its inoperative position in which fluid from the pump 21 is fed along passage 22, 23, up through the bore of the piston 2 and then. into cylinders 16, 18 for the rams 17, 14 along passages 31, 28, 27; it is returned to the pump from the cylinder 16 along a passage 30. Movement of the ram 17 to engage the grinding rollers, and of the ram to couple the drive for the feed rollers, starts when an edge b on the valve seals the bore 4 against upward movement of the fluid which then passes down the bore past edge d on the valve and along passages 33, 25, 24 into the cylinders 16, 18 behind the rams. Displaced fluid is discharged from the cylinders through the passages 27, 28, 31, past an edge a on the valve, and out to the pump through passages 32, 29. When the valve 3 has been depressed fully to contact a stop 34 at the bottom of the bore 4, the edge b and a further edge c on the valve will have sealed the bore 4 completely so that the fluid circulating round the piston 2 from the passage 22 acts to displace the piston against the influence of a spring 5. This displacement operates the feed gate and restores the flow of fluid down past the edge c. If the head of grain is insufficient to effect closure of the bore 4 by the edge c, the feed gate will not be raised, although the grinding rollers may be brought together and the drive to the feed rollers coupled. When the rams have reached the end of their travel, fluid flows back to the pump from the cylinder 16 through the passage 30. A gauge 19 in the cylinder 16 indicates the pressure between the grinding rollers. When the level of material to be ground has fallen, the springs 5, 7, 20 reset the valve 3 and the piston 2 to the positions illustrated and the rams 14, 17 are returned by the fluid.
