Patent GB-632575-A (GB)
Title: Improvements in or relating to hook structure
IPC: E21B19/04
Filed: 1946-04-04
Abstract: 632,575. Hooks. BYRON JACKSON CO. April 4, 1946, No. 10408. Convention date, April 28, 1945. [Class 89 (ii)] Relates to spring hooks of the type used in drilling oil wells and consists in a structure having a shank slidable in a housing as limited by stops and resisted in one direction by springs provided with prestressing means not subject to the load transmitted through the stops. The hook 1, Fig. 1, is pivoted at 2 to a shank 3 sliding in a housing 4. Flats 15 on the shank terminate in shoulders 19 and slide through a correspondingly formed opening in a swivel ring 12 secured on the shank by a collar 31 and pin 32. The ring 12 rests on a ball race 13 and is reamed to form shoulders 17 coacting with those 19 to limit the movement of the shank from the housing ; inward movement being limited by the collar 32. Nested springs 8 abut the ring 12 and are prestressed by a flange member 25 and nut 29 engaging a reduced screwed extension of the shank which may be either integral or screwed and pinned in place. The nut is locked to the shank by a cross pin 33. A series of notches 35 in the ring 12 receive a catch 37 when it is required to restrain the hook from swivelling. The catch is operated by a hook-tool applied to projections 60, 61 from a head 59 on a pin 47 journalled in a housing 40 secured in the main housing 4 by a cap nut 42 having a locking-pin 45 projecting into a hole 46 in the housing 40. The locking-mechanism is thus constructed as a sub-assembly and may be removed as an entity for replacement or repair. Swivelling on the pin 47 is a sub-frame 50 biased by a spring 65 so that the locking catch is always urged towards the locking position. A projection 53, Fig. 6, from the pin 47 engages with lost motion between shoulders 55, 56 on the sub-frame, a pin 72 which carries a pair of pivoted latch members 70, 71 with a spring 77, Fig. 4, that urges the latches in opposite directions. Fig. 11 shows the parts locked in the released position by engagement of the surfaces 83, 84. When the catch 37 is to be engaged, the hook tool is applied to the projection 61 and pulled downwards. The initial rotation of the pin 47 does not move the subframe 50 on account of the lost motion at 53 until a cam 80 has tripped the latch 70 when the spring 65 rotates the frame 50 bringing the catch 37 into the locking position, the end of the latch 70 passing over the adjacent part of the frame 40 and the latch 71 passing into locking engagement with the surface 88. A second cam 81 releases the latch 71 when the pin 47 is turned in the opposite direction to effect release. A modification is described with similar internal construction but arranged in inverted position. The locking-mechanism of the sub-assembly forms the subject-matter of Specification 632,631.

Title: Improvements relating to inking mechanism for printing machines
IPC: B41F31/04
Filed: 1920-04-14
Abstract: 168,933. Butler, J. H., and Phythian, T. E. April 14, 1920. Inking-apparatus.-The duct blade of an inking- apparatus is adjusted at various points of its length by fluid-pressure means operated from a control station. As shown in Fig. 1, the blade a is secured to a support b on which are mounted a number of cylinders d containing pistons e in contact with the blade. The cylinders are connected by pipes f to a hollow support g to which fluid. under pressure, which is preferably oil, but may be water, air, gas, or ink such as that used in the duct, is supplied from a tank or pump. When the cylinders d and pipes f are full of fluid, communication with the supply is cut off by means of valves formed by the conical ends of cylinders h screwed into the support g. The cylinders h contain plungers i having extension i<2> screwed through the cylinder covers h<2> and adapted to receive an operating key by which the pressure in the cylinders d may be adjusted as required. The cylinders d may be fitted with pressure-releasing valves and, when ink is employed as the pressure fluid, these valves may communicate with the duct. In a modification, the plungers i are replaced by diaphragms and the pistons e are actuated through diaphragms. An indicating plate, which may be the side of the support g, is provided at the control station to indicate to which parts of the blade the various cylinders h relate.
Patent GB-679121-A (GB)
Title: Improvements in or relating to tools for firing projectiles into metal, concrete or the like
IPC: B25C1/12
Filed: 1949-04-20
Abstract: 679,121. Firing mechanisms; projectiles. STEVENS, A. H. (Portable Industries, Inc.). April 20, 1949. No. 10450/49. Classes 9 (i) and 119. [Also in Group XXII] Tool for firing pins, studs and the like fastenings into structures comprises an elongated housing 10 of aluminium or other light metal, a slidably mounted carrier 11 being guided in the housing by a peg 13 extending into a slot 12. A partition 14 secured within the housing serves as rear abutment for a coil spring 16 bearing at its front end against the carrier. Removably mounted in the carrier is a gun barrel 17 having a screw-thread 18. The forward end of the barrel may be knurled to facilitate removal and is held stationary during assembly by prongs 17<SP>1</SP> which bite into the work-structure. The barrel has a bore 19 and a counterbore 20 at the rear receiving a reversible chamber lining 21 into which is inserted a cartridge 22. The plug bears against a flange 23 on the head of a stud 24, the head having a sliding fit in the bore. After firing the cartridge, the pressure in the chamber builds up until the flange 23 is sheared off and the stud driven out. Slidably mounted in the carrier is a firing-pin 25 held retracted by a spring 27 engaging a collar 26 bearing against a hollow nut 28. Passing through the abutment 14 is a plunger 30 carrying a disc 31 against which bears a spring 32 to hold the plunger in the retracted position. Slidably mounted on the housing is a sleeve 35 attached to the plunger by screws 36 extending through slots 37. Part of the sleeve is knurled to afford a grip for the operator. The spring 16 is weaker than the spring 32, so that in operation, when the forward end of the barrel is placed against a wall and the sleeve 35 pushed forwardly the spring 16 is compressed and thereby the housing 10 moves forwardly until it contacts the wall. Further pressure on the sleeve compresses the spring 32 so that the plunger urges the firing pin against the cartridge. Accidental discharge is prevented by rotating the housing relatively to the barrel so that the peg 13 is held in an extension 41 of the slot 12. The tool cannot be discharged unless the barrel is held against a surface, since the travel of the screws 36 is limited by the slots 37. Specification 653,503 is referred to.

Patent GB-105813-A (GB)
IPC: B65C11/04
Abstract: 105,813. Harvey, J. B. May 17, 1916. Delivery of postage stamps cut from strips. - In coin-freed machines for affixing stamps to letters, insurance cards, &c. a roll of stamps 38 is mounted in a casing 8 pivoted at 6 and containing also the stamp guide and feeding-devices, which are operated by the rocking of the casing 8 produced by its pivotal connexion 13 to the vertically moving carrier 12 of the affixing-plunger 66. Links 10 connect the upper parts of the carrier 12 and of the bracket 15. The plunger rod 57 acts through a spring 67 to depress the carrier 12, and as this descends a link 30, Fig. 5, connected to it rocks arms 24 pivoted in the casing 8 to retract the stamp-feeding fingers 21, 22 carried by slides 19, 20, in which position they are held during a part of the ascent of the plunger by a pivoted catch 32, Fig. 1. When this catch is disengaged by a stop, a spring throws the fingers 21, 22 forward to feed a stamp.. The rear fingers 22 have a longer travel than the fingers 21 so as to engage the perforations in the stamp strip if the finders 21 fail to do so. The fingers are formed in spring plates and are placed closer together or farther apart than the perforations in the strip. A projection 43 above the stamp guide 34 facilitates engagement of the feeding-fingers with the perforations, and the strip is curved laterally by the shape of the guide 34 to impart rigidity to it. The end stamp is severed by a cutter 60, Fig. 15, depressed by a spring finger 69 connected to the aflixing-plunger 66, and then, before the plunger completes its descent, the finger is disengaged from the cutter by a pin 63 and a spring 65 returns the cutter to its normal position. A full-stroke device comprises a rack 70, Fig. 1, pivoted to the casing 8 and held by a spring 72 in engagement with a lug 71 carried on the plunger 66 so as to prevent angular separation of the casing 8 and the plunger until the downstroke is completed, when a catch holds the rack in an inoperative position until the plunger has risen.
