A hollow threaded spindle 10 rotatably mounted by a bearing 28 in the body 1 carries an internally threaded collar 11 loosely supporting, by means of pins 40, struts 16. The upper ends 17 of the struts are outwardly biased by leaf springs 41 connected thereto by pins 44. In the inserted position of body 1, shown, pads 18 on the ends 17 engage an annular recess 19, defined by lower and upper lands X, Y in the tube 2. The spindle 10 is rotatable by a serrated wheel 20 rotated by a drive member 21 of a fuelling machine 22 when the latter is placed in position. Relative rotation between the collar 11 and body 1 is prevented by a key 14 and keyway 15. A rod 27 fixed to the end 3 of the body 1 extends through the spindle 10 and has a reduced end 32 engageable by a grab 34 of the fuelling machine. A fuel stringer assembly 30 is connectible by a pin 25 to a boss 23 on the body 1. To close the end of the tube 2 the assembly is lowered by the grab 34 until the pads 18 snap into the recess 19. Rotation of the spindle 10 then causes the pads 18 to engage the upper land Y and finally causes the seating 5 to move against the seating 7. To break the seal the spindle 10 is oppositely rotated to draw the pads 18 into engagement with the lower land X, continued rotation causing the lip 1a of the body 1 to engage the struts 16 to retract the pads out of the recess 19 whereupon the grab 34 may withdraw the assembly from the tube 2.

Abstract: 430,268. Knitting-machines. BLACKBURN & SONS, Ltd., G., Kirkwhite Street, Nottingham, and TOWERS, E. J., 11, Clifton Road, Ruddington, Nottinghamshire. Jan. 10, 1934, No. 895. [Class 74 (ii)] An inclined pattern wheel A is combined with a device for laying elastic thread in rib fabric so that pattern effects can be introduced by selecting the cylinder needles. The invention is described as applied to a dial machine with rotary cam box. The inclined disc A is formed with peripheral tricks gearing with the butts of the cylinder needles. Some of the tricks are filled in and only the needles corresponding to these tricks are raised. Or, as shown, the needles may be selected by bits K, K<1> sliding radially in the under face of the disc and provided with butts running in cam tracks L<1>, L<2>. The track L<1> is fitted with a cam L<3> which projects sliders K, while the track L<2> is fitted with a cam L<4> which retracts sliders K<1>, so that, normally, sliders K are active and sliders K<1> are inactive. This normal disposition of sliders may be reversed by a pivoted cam M which, when moved to the position shown, projects short sliders to active position and retracts long sliders K to inactive position. The elastic thread is fed by a grooved spring roller G carried by a block H. The roller G is traversed over the disc A, to vary the rate of feed, by a screw H<2> passing through the block and rotated by star wheels H<3>, H<4> under pattern control. The cam M is also put in and out of action by star wheel and tappet gear.

Title: Improvements in automatic rock drilling means
IPC: E21B44/02
Filed: 1965-10-12
Abstract: 1,056,369. Drilling. ATLAS COPCO A.B. Oct. 12, 1965 [Oct. 14, 1964], No. 43208/65. Heading B3C. [Also in Division B4] An automatic rotary-percussive rock drilling machine comprises a rock drill 10 mounted on a slide 11 which is movable forward and backwards along a shell 12 by means of a reversible feed motor 18, a limit switch 71 being mounted on the forward end of the shell so that when operated by the rock drill a reversing valve 60 is actuated via a circuit 70, 77, 78 and servomotor 60a thereby causing the rock drill to return to its rearward position. The reversible motor is compressed-air operated and connected via feed lines 54, 55 to a control valve 51 communicating with a main feed line 39 which is connected via a diaphragm actuated valve 32 with the pressure source. A second control valve 40 is connected via a passage 36 and a line 42 with the rock drill. A third control valve 44 is provided for controlling flushing water through a line 48, a servo-operated valve 50, line 49 and a bore 22 in the drill bit 15. In operation, with the rock-drill in its rearward position so that an abutment 76 on the slide is actuating a rear limit-switch 72, a manually-actuated valve 87 is operated so as to admit air to open the diaphragm-controlled valve 31 thereby allowing the air to flow via the valves 40 and 51 to actuate the rock-drill and the feed motor respectively, water is also fed to the drill bit via valves 44, 50. The slide then moves forward on its drilling stroke allowing the rear limit switch to move to its alternative position and thereby, via lines 85, 89, maintain the diaphragm valve open. At the completion of the drilling stroke, the forward limit switch 71 is operated which then, via the servo-circuit 70, 77, 78 actuates the reversing valve so that the feed motor reverses the drill slide. Simultaneously, the air for operating the rock drill is throttled via a plunger 80 in the valve 40 and the reversal of the pressure to the feed motor causes actuation of a second servo-circuit 81, 84 so that the delivery of flushing water is replaced by flushing air via a conduit 47. The rock drill returns to its rear position thereby actuating the rear limit switch so that the air to the diaphragm valve is exhausted and so allows the latter to close. In a modification, Fig. 11 (not shown) the rear limit switch is dispensed with and replaced by a shuttle valve 105 for controlling the reversing valve 60 and the throttle plunger 80. A further valve 100 is provided for controlling air fed to a motor 104 for rotating the drill bit. The pneumatic controlling circuits may be replaced by hydraulic or electric circuits.
