Abstract: 9459. Nobel's Explosives Co., and Hodge, H. D. May 1. Cartridge-loading machines and apparatus.-Relates to capping-machines. The cartridges 1 are placed on an inclined table x head downwards ; they slide down on to a rotating disk b and are carried thereby through a guideway b<3> to a platform c. An irregularly-toothed rotating wheel b<4> 'prevents jamming at the mouth of the guideway b<3>. Cartridges that miss the guideway are carried round to an inclined bridge b<6>, which pushes them towards the circumference where they can pass underneath the bridge. The cartridge on the platform c is tilted by a rocking sector d over a stop c<2>, falls through a hole c<6>, and is there held by spring jaws c<5>. The cartridge, during this stage, is guided by a wall c' and a flange c<3>. A reciprocating presser e then comes down on the cartridge and forces it past the spring jaws c<5>, whereupon it falls over one of a number of pins on a table f <1>, rotating step by step, by which the cartridges are carried round for the various operations. The first punch h stops the machine, if a cartridge has not been supplied to the corresponding pin f, by a lug h<1> thereon coming down over and deflecting a rockiog sector i, and thereby releasing an arm i<3> from a shoulder i<5>, so that the rod i<7> connected thereto is raised by a spring i<8>, an arm i<9> is brought in the path of a stop i<10>, and a clutch (not shown) is thrown off. The next punch k clears and sizes the pocket in the head of the cartridge, which is adapted to receive the primer. The punch k<1> clears the communication hole at the bottom of the pocket. The punch n pushes a primer a little way into the pocket, the primer being fed as described below. The punch n<1> pushes the primer a little further in, and the punch n<2> pushes it home. Contact-pieces may be provided on the punch n' and on the frame g<1> respectively, so that if a primer is missing, they come in contact with each other, as the punch n<2>. comes down, and an electric signal is given to the operator. At the next step, the cartridge is picked up off the pin f by a hollow reciprocating plunger o, provided with slidable weighted jaws o<1>, Fig. 16, which grip the head of the cartridge. The cartridge that had been picked up at the preceding step is simultaneously raised within the plunger o. The capped cartridges thus pass one at a time up the plunger o and are delivered at the top thereof. The plunger o may be connected by a telescopic joint with a tube, which passes over the machine and drops the cartridges into a receptacle placed beneath its mouth. A punch p stops the machine, if a cartridge has not been picked up, by deflecting a lever p<1>, which then rocks the sector i. The machine may also be stopped by a handle j. The primers are fed to a platform l<8> in a manner similar to the feeding of the cartridges, except that jamming at the mouth of the guideway is prevented by a vertical arm rocked by a cam l<7>. The primer on the platform l<8> is picked up by spring-controlled fingers m<6>, which are then rocked through two right-angles so as to bring the primer over the cartridge underneath the punch n. The wall l<3>, Fig. 13, which retains the primer on the platform l<8> is mounted ou a spring l<4>, so that the rocking- fingers m<6> may depress it to get at the primer. The shafts d<2>, m<3>, on which are mounted the sector d and the fingers m<6>, are rocked by reciprocating racks d<5>, m ; the pinions d<4>, m<1> in engagement therewith are held by friction between collars d<3>, m<2>. The angle through which the shaft d<2> rocks is accurately defined by adjuslable stops d<9>. The turntable f has ratchet teeth f <9> and is rotated step by step by a spring-controlled pawl f <8> pivoted to a slide f <6>, which is reciprocated by a link f <5>, a rocking lever f<2>, and a crank-pin f<4>. The punches and the racks are mounted on a carrier g reciprocated by a rod a<8> and cranks a<9>. The presser e is operated by the carrier g by means of links e<3>.
