T allwhom it may-c'qncern:

' 't'known that we, Sir ARTHUR TREVOR DAWsorf,-knight; and JAMES HORNE, both ,-,subjects'of the-King of Grreat Britain, re-

siding,"f respectively, at Vickers House, ';Broadway,- .Westminster, in the county of 'LbndQnyEngland, and Naval Construction Works; Barrow-in-Furness, in the county of ,jLancaster, England, have invented certain 'jnewjand useful Improvements in' or Bel'ating 'to Ammunition-Hoisting Apparatus, of which the following is a specification. i *This' invention relates to ammunition hoisting apparatus of the kind in which the projectile and powder charges are raised in a hoist cage'to a working chamber where I i they are transferred to 'an upper or gun loading cage which carries the projectile and powder charges 'to' the breech of the gun.

addition to the said gun loading cage, an auxiliary projectile cage or hoist, the chief purposes of which are to enable the guns to N be supplied with projectiles from the workingchamberin the event of the gun loading cage becoming inoperative and also to replenish the projectile bins in the space inclosed by the shield. The cage is preferably provided with a pivoted tray which is capable of being moved about its pivot by hand, so that it can be caused to assume an approximately vertical position prior to the ascent and descent of the cage, and an approximately horizontal position when it is desiredf to load the tray in the working I chamber and to remove the projectile when the tray isabove the shieldfioor.

In order that the said invention may be clearly understood and readily carried into effect we will describe the same more fully with reference to the accompanying draw ings,'in which:-

-Figures 1 and 2 are respectively a side elevation and an end elevation showing in a more or less diagrammatic manner a constructional form of our improvements, and v Fig. 3 is an enlarged view of the auxiliary projectile cage.

A is the shield and A the working chamber, B represents the auxiliary projectile cage and B, B are its guide rails. B is the projectile tray which is pivoted to the cage at b". C is the press for raising the said UNITEDSTATES L enrnun-rrrtnvon awson, or wEsrMInsrER, Lennon, ND JAMES HORNnor I SSIGNORS T0 vIcKEns LIMITED, vor WEST?" I Specification of Letters Patent.

auxiliary cage. It will be observed. thatin Figs. 1 and 2-the said cage is shown in'two different positions which as a "matter of fact are never occupied by the cage at'any one time. 4 j

In the example shown the hoist rope C is attached at 0 (Fig. 2) tothe'underside of the Patented 6, 1919. L Application filed May 15,1915 'Serial No.28,492. I

shield floor at one side of'the guide rails B B and after passing over sheaves b 6 carriedby the lowerpart of the cage B is led by another sheave 6 arranged at the other side of the'guide 'rails to" the ram of the press C; in this manner a clear space is obtained to enable the tray B to be swung to and'from its horizontal position-when in the working 'ehamb er" without any danger of fouling the hoist rope, andthe' latter is'conveniently arranged wholly below the shield floor. 7 It will'be obvious thatan electrically or otherwise driven winch may be used instead of the press C for hoisting the cage.

A locking device is employed for retaining the tray B in either its vertical or its horizontal position, this device preferably comprising, as shown in Fig. 3, a spring catch or bolt 6 carried by the tray and adapted to engage with one or other of two notches b, 6 formed in a quadrant B on the cage 1 B; this spring catch is capable of'being disengaged from the notches by a pivoted handle B The guide rails B, B for the cage are preferably disposed between the girders at the rear of the turntable and may be straight but inclined slightly to the vertical. The shield floor is formed with a hole to enable the cage to pass to the upper side of the floor and this hole maybe closed by a door or shutter when the cage is not in use.

The projectiles may be placed in position on the tray by a grab A or the like carried by a rail A in the working chamber A and a similar device a maybe employed within the space inclosed by the shield for removing the projectiles.

The cage may as shown have a transverse tie bar B at its upper end; and in this event after a projectile has been placed on the tray B in the position shown by chain lines in Fig. 3, it must be pushed backward until its base bears against the end of the tray prior to its being tilted into the vertical position. Similarly prior to the removal of the projectile it must be moved forward in the tray What e claim and desire to secureby Letters Patent of the United States; is*: j
