Application filed March 12, 1895.

To all whom it may concern:

Be it known that we, HUGH A. KIN GSLAND, of Belleville, and JOHNS. SANGER, of Orange, Essex county, New Jersey, citizens of the United States, have invented certain new and useful Improvements in' Explosion-Motors, fully described and represented in the following specification and the accompanying drawings, forming a part of thesame.

This invention relates especially to that class of motors in which explosives of high power, like gunpowder and fulminate, are employed, the mechanism embracing a power cylinder or gun, a piston-rod fitted to the bore of the same, feeding mechanism for supplying a series of charges to the base of the gun through a feed-duct, means for closing such feed-duct before each explosion, and means for firing the charge. The piston-rod is preferably checked in its forward motion by an air-cushion which operates to return it to its initial position. The reciprocating motion of the piston-rod is converted into a continuous rotary motion by means of an intermittentlyacting clutch, which is applied to the powershaft and oscillated by a link having a cam connection to the rod, such connection being adapted to greatly reduce the violent intermittent movement of the rod. Aheated needle is shown herein for firing the charge, and mechanism adapted by the tension of a spring to operate voluntarily when released is provided to actuate the feed mechanism, the gate in the feed-duct, and the firing-needle. A settinglever arranged obliquely at the side of the piston-rod is moved by a pin upon the latter during its forward stroke, and such lever operates to set and lock these voluntary mechanisms, which are subsequently released in successive order by an actuating-sprin g which is simultaneously compressed by the lever. A fluid-regulator or other suitable brake controls the reaction of the spring, and thus determines the velocity of the movements. Means for varying the effect of the brake or regulator serves to determine the rapidity of These improvements are embodied in one form in the annexed drawings, in which- Figure 1 is a plan of an explosion-motor. Fig. 2 is aside elevation of the same; Fig.3,

a plan, partly in section at the center line where hatched, of the charging and firing apparatus with the piston-rod wholly projected. Fig. 4is a vertical section, where hatched, of the power-cylinder and its feeding mechanism with the piston-rod retracted within the cylinder. Fig. 5 is a side elevation of the parts shown in Fig. 3 with the feeding mechanism set and locked by the positive motion ofthe setting-lever and the actuating-spring cylinder partly in section where hatched. Fig. 6 is an elevation of the rotary carrier for feeding the charges with its actuating mechanism unlocked, the parts being shown in section where hatched at the center line of the locking-pin. Fig. 7 is a rear elevation of the motor, excepting the lower part, where broken away for'want of room, the needle and its carrier being retracted. Fig. 8 shows the under side of the parts exhibited in Fig. 5, with the frame and the spring-cylinder removed and the stop-lever s omitted to. expose the le Ver k. .Fig. 9 is an end elevation of the needlecarrier retracted and its attachments. Fig. 10 is an end elevation of the same with the needle-carrier guide in section at the dog for securing the carrier.

Adesignates the frame of the motor, which may be of any suitable character; B, the power cylinder; B, the piston rod, fitted loosely. to the cylinder; 0, a guide adjacent to the same, carrying a hollow shield O; D, guides for the piston cross-head D E, an aircushion cylinder into which the outer end of the rod B extends when discharged from the power-cylinder. The cushion-cylinder is adjustably closed at its outer end by cap E to vary the effect of the air-cushion.

The breech of the cylinder Bis clamped in a bearing B and is formed with projection B behind the bearing to sustaina round support H, containing a rotary carrier F, which is provided with a series of powder-chambers F. These chambers are. supplied in succession from a hopper F The breech of the cylinder B is closed bya plug G, which is formed upon its front end with a nipple 1), containing an explosion-chamber b. A passage 0' is formed in the top side of the nipple to admit the charge, and a needle-hole c is formed in the side of the nipple to admita heated needle for firing the same. A

feed-duct (1 extends from the passage 0 upward through the breech and support H into coincidence with the chambers F. The butt of the piston-rod is fitted loosely to the cylinder B, as shown in Fig. 4, and is recessed to fit the exterior of the nipple, preferably with a taper-joint, as shown in said figure. The butt thus serves to close the passage 0 and to confine the charge in a closed chamber when exploded. The needle-inlet or needle-hole 0 extends laterally through the recessed butt of the piston, as shown in Fig. 7, to receive the firing-needle. A plug-valve e is inserted in the duct (Z and provided with arm (1 to close the same, as shown in Fig. 4,

prior to the explosion. Such arm is moved by an.actuatingspring, which is set bythespring iunder tensionthe stop engages a stud The.

5 upon the slide, as shown in Fig. 5. plug 6 is furnished with a cam 'g, (shown in Fig. (3,) which when the plug is turned, as shown in Fig.4, engages a tooth upon'the lever 8 and turns the stop away from the stud s, thus unlocking the slide and permitting the spring 1' to project the slide forward, and

thus actuate the lever and pawl f to turn the rotary carrier F. The carrier is provided with a series of latch-holes s and when thus.

turned a locking-pin h is pressed bya springs, Figs. (5 and 8, into one of saidholes. A ratchet-pin having beveled end 0 is also inserted through the support II to engage the holes S in succession. Both pins are fitted through bushings r, inserted through thesup port H, as shown in Figs. 6, 7, and 8, and the ratchet-pin 7' is pressed normally upwardbya spring r Fig. 8, the end of which plays in a notch in the outer end of thebushings. A lever is, pivoted to the support H, adjacent to the locking-pin h, Figs. 5 and G, has one arm arranged to rest upon the stud s and the op-. posite arm engaged with the pin or head 0 of the locking-pin h. hen the slide I isretracted, as shown in Fig. 5, the stud s actuates the lever 7; to retract the locking-pin, and thus permits the rotation of the carrier F upon the subsequentautomatic movement of the slide, which is eifected by the shifting of the stop-lever s by the rotation of the plug e, as above described. The setting-lever,

which is pivoted by the side of the piston-rod, K

has its rear arm J extendedin proximity to the arm cl and its front arm J inclined upwardly, so that a pin K upon the cross-head D depresses the outer end of the lever when the rod is projected. A slotted arm c, attached to the valve-plug e, is actuated by a pin 6 upon the arm J, which thus turns the plug to open the duct, as indicated by the dotted lines (Z in Fig. 5. Such movement also operates to retract and lock the slide I by means of a pinion l, with teeth arranged to engage a tooth l upon the under side of the slide. The. pinion is secured to a ratchetwheel Z which is rotated interm ittingly by an arm and pawl 1, which are connected by link twith the arm (1. The. slide is shown unlocked and projected forward in Fig. 6 with a tooth of i the. pinion in readiness to retract the slide, while such retraction is shown com.- pleted in Fig. 5 and theslide locked by the stop-lever s. A spring .5 Figs. 7 and 8, is provided to raise the stop 8, the upper half only of the spring being shown in Fig. 8, and only the hole by which its end is fitted to the stop being. shown in Fig.5. The pinion remainsstationary duringthe movement of the slide and its teeth are made a sufficient. distance apart to clear the log L when the latter is carried forward by the slide, as shown in Fig, 6. The pawl Z rotates the pinion intermittingly, in conju-nctionwith the rotation of theplug-valve e, by means of its connection through link i with thearm d. The arm. J is connected by link j to a plunger L, having a piston L fitted to a cylinder M A. spiral spring. L isconfined between such piston and the'upper head of the cylinder, and the movement of the arm J, effected by the pin 7c, opcrates to compress the spring, shown in Fig. 5.

The cylinder M is provided at its lower end with an escape-valve on, which connects by a passage m with an adjacent cylinder M. The cylinder M below the piston. is filled with fluid 072 which extendstthrough the passage m andupward a suitable distance into the cylinder M, and the valve m is held slightly open by an adjustable screw m to permit the fluid to escape from the cylinder M at a regulated velocity.

A shaft P is connected by arm'p and a link 19 to the arm J to setthe firing device for antomatic operation. Such device consists of a needle it, held by carrier U in a guide U at the side of the breech." shown held in a retracted position by a pawl u, with-theneedle surrounded by the flame n of a spirit-lamp U The needle is formed with a tapering shank wand a socket v is formed in the side of the breech, which is;

plugged by such shankwhen the needle is projected into the explosion-chamber, as indicated by the dottedlines A roll w is projected from one side of the needle-carrier to engage a spirally-faced cam WV, fitted to the rear end of the shaft P. A spring 10 is attachedto the support of the needle-carrier and operates to press the carrier forward, as indicated by the arrow'nc, and is thus adapted to project the needle automatically into the IIS The carrier is explosion chamber. Such projection'is effected, after the charge is in the chamber and the plug-valve closed, by means of a lever N, Figs. 5 and 7, which is connected at one end with the pawl 10' by a link y and at the other end is provided with a toe n to engage a collar L upon the plunger L. The collar is made adjustable by means of a set-screw and is so set as to actuate the lever N at the extremity of the plungers spring movement. A notch u is formed in the needle-carrier, and when the same is projected the notch is engaged by a dog a The dog is formed with a tooth adjacentto its pivot to engage a spring a and swings above and below its point of contact therewith as the dog is raised and lowered. The latch is formed in its outer end with a notch c and the cam IV is formed at its upper end with a tooth 10 to fit such notch and to give the dog a limited movement in either direction.

In Fig. 10 the cam is shown turned in the reverse position to that shown in Figs. 7 and 9, which show the needle bar retracted and locked. In such reverse position the tooth 10 turns the dog down into contact with the needle-bar, against which it is subsequently pressed by the spring a until the notch 20' comes beneath the dog, which immediately falls into the notch and secures the needle in the hole 0 during the explosion. The first movement of the cam caused by the first mo-' tion of the setting-lever after the explosion lifts the dog from the notch 10 and then retracts the needle-carrier, as shown in Fig. 7. The power generated by the explosion is transmitted to the shaft I by a clutch-wheel J which is intermittingly impelled by dogs a, attached to a clutch-plate 0 The plate is oscillated by an arm P, to which a gradually-accelerated motion is imparted from the piston-rod by a curved bar T, attached tangentially to the rod and acting upon a roller or rider '6. S with the arm P and by a link S with a fixed center S The bar T is curved backwardly and upwardly, and the rider at the beginning 1 of the discharge-stroke rests upon the lowest point of the bar, where its curve is nearly parallel with the piston-rod. The rider is carried by the link S around the center S and, as the bar is forced forward with the pistonrod, moves upward around such center, being raised with accelerated velocity as the bar curves gradually at a greater angle to the rod. The parts are shown in Fig. 2 in dotted lines at the extreme of their movement. The rotary power-shaft is thus protected from. the primary shock of the explosion, and a motion which is slow at first and afterward rapidly increased in velocity is imparted to the powershaft by the curved bearing-bar and its rider. The curved bearing-bar and the rider thus form an intermediate mechanism which transmits the violent motion of the piston-rod with gradually-inoreasing velocity to the power-' shaft and avoids the danger of shocks and Such rider is connected by a linkconcussions which would result froma direct connection.

The cap E, when loosened, permits a partial or graduated escape of the air, and the compression of the air in the cushion-cylinder E may thus be regulated by the cap to secure the return of the piston-rod to the proper point within the power-cylinder B, and means is provided to prevent the rebound of therod from such cylinder when thrown into contact with the charging-nipple in the base of the same. Such means consists of a catch a, hinged upon the frame A, to engage the front end of the hub, which connects the bar T to the piston-rod when such rod is in the bottom of the power-cylinder. Alever g is pivoted to the frame adjacent to a pin 0 upon the setting-lever and is extended over a lug a upon the end of the catch a. When the setting-lever is depressed by the forward movement of the pin K, the catch-springs upward, as indicated by dotted lines a in Fig. 2, to look the piston-rod'in the cylinder B; but when the setting-lever is reversed by the auxiliary actuating-spring L as indicated in Fig. 2, the pin 0 operates upon the lever g to retract the catch, as shown in full lines a in Fig. 2. The'piston-rod is thus unlocked prior to the explosion and is free to move forward, as required.

The hollow shield C before the power-cylinder serves, with the guide 0, adjacent thereto, to intercept the products of the explosion and to prevent the fouling of the mechanism beyond such shield.

In practical operation the firing of the charge sets and locks the slide I and the needle-carrier U and opens the plug-valve e. The expansion of the auxiliary actuatingspring L controlled by the fluid m first retracts the stop 8 from the slide I by means of the cam g, (see Figs. 5 and 6,) thus turning the powder-carrier F and depositing a charge in the duct d. The locking-pin h, when the slide moves forward, is pressed upward by the spring 3, (see Fig. 6,) and thus arrests the motion of the carrier at the proper point by springing into the latch hole 3 The ratchet-pin, having beveled end 0", (see Fig. 7,) is forced downward by the forward rotation of the carrier and by its automatic e11- gagement with the succeeding hole prevents any reaction of the carrier; The valve 6 is next closed and the latch a depressed, as shown in Fig. 2, and finally the collar L engages the toe n upon the lever N, thus releasing the needle and permitting it to fire the charge. The forward movement of the piston-rod produces the same effects upon the setting-lever, and the rapidity of the charges is regulated by adjusting the valve 1% by the screw m The impulses of the piston-rod are transmitted successively to the rotary powershaft, which is shown in Fig. 1 provided with a fly-wheel V to maintain the motion between such impulses. The cross-head of the pistonrod is preferably provided with a spring or air-cushion, asclaimed in United States Patent No. l97,246, dated May 9, 1893,'bywhich,. in conjunction with the curved tangential bar and its rider, power may be generated with very great economy from gunpowder and a continuous rotary motion obtained without shock or jar. The fluid which is forced past the valve m by the piston beneath the spring Z operates as a brake upon thereactionmovement of the spring, and it is obviously immaterial what form of brake be used to perform this function.
