Title: Improvements in or relating to tapering pin-and-box type threaded couplings
IPC: F16B39/30
Filed: 1956-10-29
Abstract: 806,553. Rod, &c. couplings. BATAAFSCHE PETROLEUM MAATSCHAPPIJ N. V. DE. Oct. 29, 1956 [Oct. 31, 1955], No. 32956/56. Addition to 786,652. Class 99(1). [Also in Group XXIV] In a pin-and-box coupling, e.g. for a welldrilling string, the pin 2 and the box 3 are each provided with tapering screw-threads 7, 8 at least one of which when unloaded, deviates from a normal tapering screw-thread in such a way that when the coupling has been tightened up the inner flanks of the screw-thread on the pin and the outer flanks of the screw-thread on the box are more heavily loaded than the other flanks of the screw-threads. A normal tapering screw-thread is defined as one in which the pitch and taper are uniform throughout the length thereof, and the outer and inner flanks are defined as those flanks which are directed respectively away from and towards a plane M normal to the axis of the screw-thread and bisecting the length of the screw-thread. As shown in Fig. 1, the pin 2 is provided on a drill collar 1 formed with a shoulder 5 which is in contact with a shoulder 6 on a drill collar 3 formed with the box 4, and the screw-threads have flattened tips, and roots. The coupling may be made up by the application of mechanical power, or the box may be heated before being screwed on to the pin so that consequent shrinkage thereof contributes to the loading of the screw-threads. A local variation of pitch may be provided on one or both of the screw-threads near the middle thereof, or the pitch of the screw-thread at the smaller diameter end of the pin may be smaller than the pitch at the larger diameter end of the pin whilst the pitch of the screw-thread on the box is larger at the end corresponding to the smaller diameter end of the pin than at the other end of the box. In another case, both the screw-threads have a constant pitch, the pitch of the screw-thread on the pin being smaller than that of the box, and the taper of the pin at the larger diameter end being smaller and at the smaller diameter end being larger than the taper of the box. Further, the pitch of the screwthread on the pin may be smaller than that of the screw-thread on the box, the difference in pitch decreasing from the middle of the screwthreads towards both ends ; preferably, the pin has a normal tapering screw-thread, and the decrease of the difference in pitch is continuous. Specification 799,028 is referred to.

Abstract: 785,372. Cutting machines. FORSTERS MACHINE CO., Ltd. Dec. 1, 1955 [Nov. 17, 1954], No. 33312/54. Class 31 (1). [Also in Group XVII] A machine for facilitating the manual wrapping of an article comprises a table 2 over which wrapping material 16 is drawn by the operator from a roll 7 supported from side bars 8 of the table framework. The material passes over a guide roller 17, under a friction member 18 which prevents retrograde movement, through an opening in a vertical cover plate (not shown) and over a plate 23 formed with a slot 22 embracing a transversely-movable cutter 19, Fig. 3. The latter is mounted in a block 28 carried by an endless chain 26 passing over end sprockets 29 one of which is driven through a reduction gear 30 by an electric motor 31 controlled by a foot-operated switch 6. Depression of the latter energizes the motor to cause the cutter to travel along the upper run of the chain, thus severing a wrapper from the supply, and return to its initial position along the lower run, a projection on the chain then operating a second switch to de-energize the motor. The block 28 also supports a guard 24 having an end portion 25 which depresses the material 16 into the slot 22 to facilitate the cutting operation. The plate 23 may be replaced by a bar having an edge cooperating with the cutter 19. The table 2 may be provided with marks to enable predetermined lengths of material to be drawn from the supply roll, and several supply rolls of different widths may be mounted on the bars 8 so that the operator may select a material suited to the dimensions of the article 32 to be wrapped.

Title: Improvements in upsetting or forging machines
Inventor: WILSON GEOFFREY
IPC: B21J9/18
Filed: 1969-07-03
Abstract: 1,224,260. Forging. B. & S. MASSEY Ltd. 3 July, 1969, No. 33511/69. Headings B3H and B3M. [Also in Division F2] An upsetting machine has one of its dies 30, 121 mounted to perform circular rocking motion during operation and its support member 26, 118 and the die carrier 28, 127 are separated by bearings 34, 132 which can compensate for dimensional changes in the die and carrier due, for example, to heating. In one embodiment, Fig. 1, the die 30 is secured by bolts 32 to a hemi-spherical carrier 28 supported on three spaced arms 24 of a yoke 23. The carrier has preferably three bearing pads 34 which cooperate with the face of the support 25 fixed to the machine frame 10. Alternatively, the pads can be mounted on the support, Fig. 5 (not shown). The pads have hemispherical protuberances 36 which seat in recesses in the carrier. The yoke is mounted on a stub shaft 18 whose axis is offset from that of the drive shaft 13. The die carrier 28 is prevented from rotating by gear rings 40, 43 on the carrier and machine base 44 respectively. The shaft 13 is driven by a pulley 15 and has a flywheel 16. The carrier 28 is urged towards the support surface by springs or Belleville washers. The bearings 19 for the stub shaft 18 are lubricated via a passage 46 and the bearing pads 34 via a passage 47. The bearing surface of each pad has recesses (48), Fig. 1a (not shown), for retaining the lubricant. Alternatively, the bearing may be hydrodynamic. In operation rotation of the shaft 13 causes the yoke 23 to rock which in turn rocks the die carrier 28. The surface of the die may be complex since it does not rotate relative to the workpiece. In an alternative embodiment, Fig. 2, the drive shaft 110 has an extension 116 of two parts 117, 118 arranged so that relative rotation of the parts adjusts the amount of rock of the die 121. The die carrier 127 is separated from the lower part 118 by radial and thrust bearings 132. Lubricant passageways 135 are provided for the bearings. In a further embodiment the die carrier (220), (226), Figs. 3 and 4 (not shown), is separated from the support (211), (223), by conical bearing members (214), (224). The surfaces of the support, the member or the carrier are provided with lubricating reservoirs. The members may be two-part to permit angular adjustment of the die carrier.
