In the form shown I prefer to arrange tho detail view in longitudinal section showing hopper upon or adjacent 'to the roof ol' the loo 5o the consiruction and arrangement of chambuilding, as indicated in Fig. i?, suitably inber trom which the separate charges of powl closingthe samein a casingordoi'iiiei'-vcindow l) to pr tect the same from 'the elements. At'

the delivery end of the hopper form e, chamber E, in which is suitably mounted a drum F, having a series of pockets or chambers Gr in the peripheral surface thereof,r as clearly shown in Fig. 3, each pocket or recess adapted to receive a small amount of powder as said drum or cylinder is revolved. The chamber E terminates at its lower end ina tube H, and the drum F forms a partition between the delivery-tube H and the bottom of the hopper A, as clearly shown. The operation of this feature of the invention is as follows: The 'powder to be fed to the machine is delivered in bulk to the hopper A. New by revolving the drum F the pockets in the peripheral surface thereof as lthey enter the hopper A. during the revolution of said drum beeofnie iiiled with powder, which powder is carried by the rotating drum until such pockets reach the extension or tube H, whereupon he powder is deposited or delivered from the pockets or recesses in the drum into said tube or channel. .Thus the drum F operates as a G, cut oft for the hopper and eiects the transfer o the powder from the hopper only in small quantities. y

The powder-transfer drum may be actuated in any suitable or convenient manner at a speed dependent upon that required ior'properly presenting or feeding the powder to the loading-machine. i have shown a simple and convenient arrangement for actuating the transfer-drum F, but io which my invention is not limited orrestricted. inthe ferm shown l provide the drum with a feedracir in the form oi. a ratchet-dislt J',- with which engages a pawl K, carrie-d bya lever lli, suitably mounted, and to one end. of which is connected an actuating-rod M. By suitably projecting the actuating-rod M the lever il is rocked, thereby causing the pawl K to `the teeth of ratchet-disk .l and eilect a rotation thereof, and with it the transferdruin ii", a step-by-step feed or rotation being thus imparted to the transfer-drum. if desired, a spring N may be arranged to oppose the rocking movement of lever L. Of con rse many other specifically different arrangements of apparatus and. devices may be devised for effecting the actuation ot' this powder-transfer drinn and still fall Within. the spirit and scope of my invention. do not desire, therefore, -to be limited or restricted to the particular construction shown and described.

The actuating-rod M may he projected or #actuated in any suitable or convenient manner. i have shown a simple and convenient arrangement, to which, however, the invention is not limited, wherein l connect said rod with the reciprocating head O or other convenient movable part of the loading-machine througha connecting-pitman P, where by upon each reciproeation of the head O a rptuiivc movement through acertain distance it. imparted io the transfer-drum if. Recipe'iefive rocation may be imparted to head in any suitable manner, as by means of a crank connection with the main driving-shaft ofA the machine. In order that a certain degree of vlost motion may be provided between rod Mv and oonnecting-pitman P, so that the full stroke of head O mayuot be imparted to rod M, I prefer to provide the end ot' pitman P with a transverse slot, as indicated atQ,Fi'. 4, in which slides a cross-pin R in the end of rod M or link connecting said pitman with said actuating-rod. Thus the pitmanP may travel through a portion of its stroke before the pin R reaches the limit of slot Q, and hence before therod, IVI begins to move. If desired and in order to still further regulate the distance through which the transfer-drum F is rotated upon each reciprocation of its actuating-rod and connecting-pitman, thus regulating the rapidity of supply or transfer of the powder from the hopper to the loading-` machine, l may provide an adjusting connecting-link S, in which the proximate ends of said actuating-rod and pitman are suitably connected. in the form shown this link comprises a plate having dovetailed Ways formed therein, as indicated at T, Fig. 8, iu which ways slides a block W, to which the end et rod M is connected, and I provide a series of holes or sockets A/ -in said link, in any one' of which may he inserted a pin or stud,vso as to confine the block W' therein. Thus by removing the pin 'or stud from one of said holes or sockets andplacing the same in another the stroke of rod-M may be regulated, thus regulating the arc through which lever L is rocked, and hence regulating the amount ot' rotation or rotative movement imparted to the transfer-drum.

From the delivery powder is delivered into a chamber B2 (see Fig. 5) in small quantities, as above explained, and from the chamber such powder 4is delivered in the form of a charge containing the required quantity for a cartridge, as will be more fully described hereinafter.

From the foregoing description it will be seen that the main body or bulk of the powder from which the supply is drawn is removed from. proximity to the loading-machine, thus reducing danger of destructive explosion by accident o'r otherwise. It will also be seen that the p wder isdelivered toy chamber B only in small quantities, 'so that in case of explosion only a small quantity of -powder will be affected.

ln order to stili ators and apparatus, I provide thefollowing construction: The chamber B2 is formed in a casing C2,vvith which casing are connected the tubes D2 E2 and the tubes F2- G2. The-tubes E2 F2 are arranged within the tubes D2 and. G?,iespectively,.the tube E2 freely communieating with the chamber B2 and the tube F2 ycommunic'ating 'with said chamber through an opening suitably closed by a fragile matcrial--such, for instance, as glass-as :mdr-

tube or opening H the further protect the operthrough the tube E2, which, as above exteiier threads of extensions J2 K2, respectively, while tubes D2 and G2 are interiorly threaded;V to be screwed onto the exterior threads of extensions J 2 K2, respectively. l) y this construction it will be seen that the interior tubes E2 F2 are wholly inclosed within the-.tubes D2 G2, respectively.' Therefore in ,case of an explosion occurring within chamzo:

ber B2 or within the tubes E2 F2 and which develops force sufficient to destroy the pipes E2 F2 the air contained within the space bctween said tubes and ltheir inclosing tubes will forni a cushion to prevent transmission of the concussion to the outer or inelosing tubes, the operation, in case of an explosion occurring within chamber B2 being to shatter theragile partition H2 between said chamber B2 and tube F2, and the compressed gases resulting from the explosion, taking the path of least resistance, will follow the tube F2 to the outer air, thus removing and reducingv the danger of destruction resulting'from the explosion, and the air-space between the inner tubes E2 and F2 and their inclosing tubes D2 G2 serving to prevent destruction of the outer tubes in case the explosion is of sufficientl force to destroy the inner tubes.

The powder is supplied from the hopper in the Imanner above described to chamber B2 plained,freelycominunicatesthcrewith. The communication between the hopper and the upper end of tube E2 is effected through a funnel L2, which communicates at one end with -the extension H and 'at the other end with the open end of tube E2. The upperends of tubes E2 and D2 are open, and therefore in case of explosion the gases resulting therefrom are notl confined in a closed space, but are free toA forded 'bythe transfer-drum F actingas a cut-.

olf for the hopper, by arranging sa'id hopper out of alinement ith the tube E2 the flash will travel freely ou!l of the free or upper end of saidttnbe, thus avoiding danger of transmitting such [lash to the powder in the hopper. u it may sometimes be desirable to provide The tubes E2 and F2 are of' means for indicating the quantity of powder contained in chamber 132. I have shown a simple arrangement for accomplishing this result, wherein I arrange a block or plumb M2 within chamber 132 to be dropped as desired upon the mass oi. powder contained therein. A' chain or cord N2connccts to said block or plumb and, leading out through tube E2 and over suitable guide-sheaves, carries one or more pointers or indexes O2, arranged to operate in connection with stationaryscales or indicators 12.,. In this manner the quantity of powder contained in the chamber B2 may be notedV at any instant in the operation of the apparatus, thus warning the operator in case of an oversnpply or an nndersupply, and hence enabling the supply to the chainber to bo adjustably regulated by adjusting the stroke of aolnlating-rod M in the manner above described.

When the plumb M2 is not being used, it may be raised or drawn up olf the powder and the cli/ain N2 fastened by a hook at the lower end, thus retaining the plumbelevatcd or suspended.

The powder may be delivered from chambor B2 in suitable quantities to form charges for the cartridges in any suitable or convenient manner and by any suitable or convenient arrangement or construction of apparatus, which may be varied, altered, or changed according to the details of construction and arrangement of the particulartype or form of cartridge-loading machine in connection with which the invention is employed. I

have shown a convenient arrangement of ture or opening across which is mounted to slide or reciprocate a powder-slide A2, said slide being suitably mounted in guides formed in th'c supportingframe plato S2. A convenient arrangement of simple construction for oil'ecting the reciprocation of the powderslide A2 is shown, wherein the end of said slide is pivotally connected to a lever 1&2, provided with a cani-slot C, in which operates a projection from the reciprocating head O or other convenient movable part. of 'the niachine. v liy this construction and arrangement it will be seen .that upon each complete reciprocation of head-O the powder-slide is moved iirst into position for the pocket Ds therein to communicate with the aperture or' opening in the chamber li2 to receive therein a quantity of powder suilicicnt to form a charge for a shell or cartridge and then into position for said pocket to register with opening R2, thus depositing such charge into the open end ot the shell-case presented in alinement with said opening or aperture R2, and finally back again into position to receive IOO another -charge from the chamber B2. In'

order to adjustably regulate the amount of powder required for each charge, the area of the charge-.pocket D3 `in the powder-slide may be varied by means 'of a nected to a threaded stud or bolt F3, tapped into a threaded seatiii the powder-slide Ai.`

Upon the movement of the powder-slide into position for the charge of powder to be delivered through aperture R2 into the'shellcase placed to receive 'it the plate E3 forms a cut-off for the powder reniainingl'in'chamber B2.

As an additional element of safetya small hole Grrs may be drilled through the table or Support upon which the shell-cases rest at point-sin line with the primer of the shell, thus avoiding danger of exploding the primer at those points where pressure is exerted by the loading devices yand which might otherwise sis cause the primer to lbe exploded. f

Froin the foregoing descriptionit willbe seen that I provide an exceedingly simple' and efiicient arrangement of safety appliances for reducing `the dangerresulting from explosions to a minimum and wherein the powder is efficiently delivered in charges of suitl able size and quantity into the shell-cases.

Many variationsiu the details of construction and arrangement would readily occur to persons skilled in the art and still fall within the spiritand scope of my invention. vI do not desire, therefore, stricted to the exact construction andl arrangement shown and described; but,
