To all whom, it may concern.-

Be it known that we, JOHN F. MEIGs and ROBERT P. SToU'T, citizens of the United States, and residents of South Bethlehem, Northampton county, and State of Pennsylvania, have invented certain newand useful Improvements in Ammunition-Hoisting -is.a plan view, partly in section on the line A and partly in section on the line B, Fig. 1. Fig. 3 is a side elevation of the hoistingapparatus. Fig. 4 is a rear view of one set 'of the transfer-rammers. Fig. 5 is a section on the line C of Fig. 4. Fig. 6 is an enlarged side view of the upper part of the'chain elevator; and Fig. 7 1s a side view of the transfer-carriage, partly broken away.

Referring to the drawings, @indicates aV rotating turret or shield mounted on circular bearings 1 in a protecting-wall or barbette b. The turret comprises a shield covering the guns 2 and a cylindrical chamber 3` below the guns, having a floor 4` adapted to sup ort the ammunition-hoisting mechanism. he present invention does not relate to the particular construction of the turret or the arrangement of the guns in the turret, and hence no detailed descri tion of these parts is necessary. Within .the turret are vertically-arranged tracks -5, upon whichl elevator-cars c travel to convey the ammunition from the lower part of the turret to the guns. Near the center of the turret and supported by the licor 4 is an elevator d for raising the ammunition from the handling-room 6 into the turret. Between the. elevator d and the track 5 is a transfer-car e, onto which the= ammunition is loaded by a series of rammers f. A second ser1es of rammers g are located adjacent to the elevatord and adapted to convey the ammunition from the transfercar to the elevating-car c.

I As shown, the elevator d comprises two sprocket-chains. 7, running over sprocket-- ,wheels 8, supported on a stand 9, which is carried by t e floor 4 of the turret. Pivotally connectedv to the chains are a series of flights 10, which are curved to convenientlyv hold the ammunition. Each of the flights is provided with a spur 11, which rests against a link of the chain and holds lthe 'flight in proper horizontal positionron the ascending ranch of the' chains. Each flight is also povided with an arm 12, which' engages av ed projection 13 at the upper end of the frame 9 as the flight approaches the sprocketwheel, and the flight is thus folded in upon the chains and retains this position in passing over the sprocket-wheel and down on the descending branch of theY chains,` as illustrated in Fig. 6. The chain conveyer passes under suitable guide sprockets 14, said sprockets being carried by the floor of the hoist-well, which well rotates with the turret. An openin 15 is provided in the floor of the turret for t e passage of the chain conveyer, and a hood or casing 16 covers the conveyer and the opening. The openings in said casing 16, through .which the rammer o crates and lthrough which ammunition is disc arged into transfer-car e, as also the..openings in each end of said car e, are closed by shutters 30, which shutters are opened onlyA when` necessary to move ammunition into orout of said openings, thus preventing sparks from dropping into the handling-room or from igniting powder charges contained in hoist d in transfer-car e. (See Fig. 7.) As

shown, the shutters are pivoted, and' each set is connected by a link 31.

The apparatus illustrated and described is capable of handling a charge of ammunition in three parts, which may include, for instance, a projectile and two bags of powder. It will be understood,how`ever, that either one or more sections of the charge of ammunition may behandled at a time. Between the chain conveyer'and the lower station of the track for the'elevating-car c is located the transfer-car e. As shown in Figs. 1 and 7 this car. has three compartments adapted to reg` ister with three 4flights of the chain elevator IOO and to receive three sections of a charge of charges of ammunition are entirely inclosed ammunition. preferably c vlindrical, being thus covered and adapte to protect the powder from sparks. The car is provided with wheels l and mounted on suitable rails 18, and means are provided for shifting it from a position registering with the chain conveyer to a posit-ion registering with the elevator-car. The` l said means, as shown, are an'electrlc motor 19 and a screw 20.

- The elevating-car c maybe of any suitable construction. As shown in Fig. 3, it is provided with three shelves or supports for the ammunition, which register lwith the compartments in the transfer-car when the elevating-car is at its lower station.

Two sets of transfer-rammers of any suitable construction are provided, one for transferring a charge from the chain elevator to the transfer-car and another for transferring it from the transfer-car to the elevating-car. These sets of rammers, as'v shown, are substantially similar. Referring to Figs. 5 and 6, which represent t-he triple rammerf, 21 indicates three remmers carried by racks 22, which slide in a frame 23 and are operated by pinions 24 on avertical shaft 25.- The shaft 25 is driven bya motor 26 and suitable connections. The construction and operation of the rammers g and fmay be the same, and a detailed description of the rammers g will therefore be omitted. As compactness is an essential feature of the mechanism, owing to the limited s ace in the turret, the rammers g are locate between the branches of the chain elevator d, as shown in Figs. 3 and 6. The rammers g are driven by an independent motor 27. Any suitable oWer mechanism is provided for operating t e elevating-car c and the chain elevator da It will be understood that a complete set of the apparatus above described may be supplied for each gun in the turret and that the apparatus may be in some instances used for supplyin ammunition to guns which are not mounte in revolving turrets. This a paratus greatly expedites the handling of t e ammunition. While one charge is being placed in the gun from the elevatmg-car c the ,transfer-car is supplied with a succeeding charge and broug t back into position to register with the triple rammer By a slight movement of the chain e evator a third charge is brought into position to register with the triple rammerf, as a number of char es may be carried simultaneously by the cIiain elevator. It will thus be seen that the elevatin -car c may be loaded instantly when it reac es its lower station, and the gun maybe ired as rapidly as the car c can be moved' up and down and the charges placed in the gun. At the same time the handlingroom is practically shut off from the turret and protected from falling sparks. The

These compartments 17 are by the casing and shutters during the.. time they are in the chain elevator and in the transfer-car, thus orreatly reducing the danger of' igniting suoli charges by sparks from the turret. Y
