Title: Improvements in or relating to Ordnance Firing Mechanism.
Inventor: ASBURY DORSEY FROST
IPC: F41A3/02
Filed: 1917-02-02
Abstract: 103,997. Asbury, D. F. Feb. 3, 1916, [Convention date]. Ordnance breech mechanism. -Relates to primer-lock firing- mechanism of the kind having a lock frame comprising a wedge, an operator bar, and an operator as described in Specification 1923/13. The invention consists in effecting the opening and closing movements of the lock frame by a slidable member, which is interposed between the. breech-screw operating shaft and the operator bar, and is reciprocated by the movements of the said shaft in opening and closing the breech. The invention is shown in Fig. 1 applied to the firing- mechanism described in the above-mentioned Specification, in which the lock frame comprises a " wedge," an operator bar 63, and an operator 67. According to the present invention, the lock frame is automatically actuated from the breech-plug operating shaft 13 by means of a pin 61 engaging a cam 56, 57 formed on a slide 51. The lock-frame operating-bar 63 is connected with the slide 51 by a lug 66 engaging in a slot 52 and maintained in the position shown for automatic working, by an operator 67 bearing against an end wall 54, which member is displaced, as described in the above-mentioned Specification when it is desired to operate the lock by hand. When the breech is being opened, the circular portion 56 of the cam is operative to open the lock, and also serves to retain the lock open. During the first portion of the closing movement of the breech, no movement is conveyed to the lock, but later the lock is closed by a telescopic spring link 68 connecting the hammer B to the operator 67, this member engaging a slot in the lug 66. The Specification as open to inspection under Sect. 91(3) (a) comprises also (1) a primer magazine and a primer guide forming the subject of Specification 110,167; (2) special electric connexions for the firing circuit forming the subject of Specification 110,168; and (3) a special form of firing-hammer forming the subject of Specification 110,169. This subject-matter does not appear in the Specification as accepted.

Abstract: 675,125. Seats. CHAPMAN, Ltd., A. W. Dec. 4, 1950. [Jan. 23, 1950] No. 1776/50. Class 52 (ii). A vehicle slidable seat is provided with a back rest which is pivoted between its upper and lower ends at a fixed point relatively to the support and has a pivoted connection between its lower end and the seat such that as the seat is slid the back rest inclination is varied without varying the inclination of the seat. As shown the seat 1 slides on the support by means of interengaging slide members 3 and is pivoted by means of a link 8 to the lower end of the back rest 7 which is pivoted at 14 to the side members 13 of the support. Any locking arrangement, is provided to lock the seat and back in its adjusted position. In place of the link 8 interconnecting the back rest and the seat an inward projection at each side such as 10 on either the seat or back rest may engage an arcuate slot on the other member. Specification 648,183 is referred to.

A die for casting tread-mould segments includes a die-body having at least one mouldsurface recess, said recess having at least one projection extending laterally from the sidewall of the recess and a pin supported within the diebody for reciprocal movement in a direction substantially normal to the mould-surface, and means for ejecting the casting and moving the projection beyond the mould-surface of the diebody. In the embodiment described, the tread to be moulded, Fig. 1, comprises ribs 3 whose sidewalls 4 are provided with undercut projections 5 extending into the grooves 2. The treadforming mould-segments 7, Fig. 5, comprise ribs 9 with undercut portions 10 to form the projections 5, and are pressure die-cast in a die 13, Fig. 3, mounted in a die-body 14 and covered by a die-cover 16 located by dowels 18. Projections 25 in the die form the undercut-portions 10 of the casting 7, and are each formed integrally with a pin 26 axially-slidable in a.bore 27 in the die-body. After casting, the cover 16 is removed and the casting ejected by pins 30 carried on a plate reciprocable by a rack-andpinion, the projections 25 remaining engaged with the undercut portions 10 of the casting and being moved upwardly therewith, Fig. 5. The casting is then moved laterally to disengage the projection 25, and the pins 26 fall back so that the projections re-engage in the corresponding recesses in the die 13. The projections 25 are shaped with ears to prevent rotation of the pins 26. In a modification the pins carrying the projections 25 serve as ejector-pins.
