Abstract: 593,092. Screwing die-heads ; taps. FAIRWEATHER, H. G. C. (National Acme Co.). April 17, 1945, No. 9623. [Class 83 (iii)] In a screw-cutting tap or die-head, the action of the primary axially -shiftable means for collapsing the cutters at the end of the screw-cutting operation is ensured by spring-loaded secondary means that impart a kick to the primary means. As applied to a collapsing tap, the body 2 has a shank 3 and radial slots 4 for the chasers 5 which are held in position by a front plate 12. Within the bore of the body an axially-movable core 7 has a tapered nose 9 with tongues 10 engaging grooves in the chasers. A spring 8 tends to move the core to retract the chasers which are set for diameter by an adjusting ring 19 screwed to the body. An axially movable collar 13 carries a cross-bar 14 which extends through a slot 31 in the body and a short slot 32 in the core and has also a semicircular trigger 16 in a slot 15. The trigger is forced outwardly by springs 18 and is bevelled at the front edge 17 to co-operate with a bevel 29 on an external, axially-movable sleeve 21. For use of the tool on a rotating spindle, the sleeve 21 is provided with a circumferential groove 24 for a fork to move the sleeve back or forward ; for use on a non-rotating spindle a work-engaging member 25 is connected to the sleeve by arms 26 and a lever pivoted on the sleeve 21 is provided for returning it to reset the tap. Several springs 23 are fitted between the sleeve 21 and the collar 13 and on completion of the screw-cutting operation the sleeve is moved back by the member 25 or by the fork in the groove 24 and places these springs in compression until the trigger 16 is depressed by the co-operating bevels 29, 17 so that the collar 13 is free to be moved back by the expanding springs. This movement imparts a kick to the core 7 when the cross-bar 14 contacts the end of the slot 32 and ensures the operation of the spring 8.

Abstract: 441,520. Fire-extinguishers. SEAT, J. L., 25, Lindberg Street, Fairfield, Connecticut,. U.S.A. March 29, 1935, No. 9910. [Class 47 (ii)] A fire-extinguisher of the gas capsule type comprises a single manual means for removing a pivoted sealing element from the nozzle and for sliding the gas capsule against a piercer. The extinguisher, shown in operating condition, comprises a casing formed from sections 12, 13 united by a partition member 14. Extinguishing liquid is stored in the chamber 20, which has a nozzle 17 and dip tube 19. A closure member 29 with a sealing plug 28 is carried by a lever 25 pivoted to the nozzle and urged to a position to seal the latter by a spring 31. The lever is pivoted to an adjustable actuating link 36, 37 which is pivoted to an operating lever 33. The latter is pivoted to the casing section 13 at 34, and normally lies along the casing, having a groove 35 to accommodate the link 36, 37. A tubular housing 40 threaded in the partition 14 accommodates a spring-pressed ball valve 44, a sliding piercer 42, and a seating member 50 for the neck of the capsule 53, which latter is further slidingly supported in a partition member 55. A spring-pressed plunger 57 for moving the capsule is guided in a sleeve member 56 threaded into the end wall of the casing section 13 and its end projects normally into a cam groove 68 formed in a spring-pressed pin 66 which is slidable in a bore formed in a fitting 61 removablysecured on the said end wall. The upper end of the pin 66 is arranged to be engaged by a nose 71 on the lever 33 when the latter is moved to operative position. Thus, movement of the lever 33 first swings the member 29 away from the nozzle 17, and then moves the pin 66 and plunger 57 to force the capsule 53 against the piercer 42. The gas, preferably nitrogen, released from the capsule passes through the bore 45 in the piercer, forces open the ball valve 44, and passes by apertures 48 into the chamber 20. The lever 33 is held in operative position by a spring bolt 73.
