Title: Improvements in Grenades or Explosive Missiles.
Inventor: RAGSDALE EARL JAMES WILSON
IPC: F42C14/02
Filed: 1917-02-01
Abstract: 126,668. Ragsdale, E. J. W. Feb. 1, 1917. Projectiles; projectile fuses.-Relates to grenades, and consists in providing (1) a safety-device for locking the firing-mechanism, which device is adapted to be released by a dragging movement applied by the hand in throwing, and (2) spring firing-mechanism comprising an inertia ring carrying a part which normally holds the firing-spring cocked, the ring being supported, before the grenade is thrown, by a number of sectors. The drawings show a percussion hand grenade. A spring- actuated striker 14 is normally held cocked by a transverse key 21 mounted eccentrically in an inertia ring 22. Sectors 24 are loosely seated under the ring, and held in place by a spring-pressed cover 25, which is itself locked by a resilient external catch C, Fig. 2. The catch is retained in the safety position by means of a detent D slidably mounted thereon and engaging with an eye 33, passing through a slot in the catch. In use, a split pin 39 is first withdrawn and the piece D is forced to the releasing position as the grenade is gripped. On throwing, the fore-finger applied to the end 30 of the catch C, disengages the catch from the cover 25, which flies off, allowing the sectors 24 to fall away. The grenade is thus armed, and when impact in any direction occurs, the striker 14 ignites a delay-action train 19 leading to the detonator 16. The safety-catch device is applicable also to time-fuse grenades.

[Also in Divisions A3 and E2] A releasable fastening comprises a bcdy, a latch 16 pivotally mounted on the body, and spring means 18 acting between the body and the latch urging the latch away from a first position towards a second position, the body having a hook portion 22 defining a recess facing in one direction, the latch having a hook portion 24 defining a recess facing, when the latch is in the second position, in a direction substantially opposite to said one direction, the recess combining in said second position of the latch to form a bounded opening 25 and the latch also having a projection 35 which upon movement of the latch from the second to the first position, passes over the recess in the body from the closed end thereof to the open end thereof, the arrangement being such that for attaching the fastening to a member 7 having a portion 23 which can engage in the opening, the latch is moved from the second to the first position against the action of the spring means enabling the portion 23 to be positioned between the recesses with the projection between the portion 23 and the recess in the body and the latch is then released whereby the spring means turns the latch to bring the recesses together to form the opening which encloses the portion 23, and the arrangement being such that for releasing the portion 23 the latch is rotated from the second position to the first position, during which movement the projection forces the portion 23 out of the recess of the body. The body comprises two plates fastened together by means of rivets, the plates being shaped to form the hook portion 22 at one end. The latch 16 is mounted between the plates on a pivot pin 17 and the spring means 18 which biases the latch to the fastening position is a leaf spring. The projection 35 is arranged opposite the hook portion 24 and in addition to ejecting the portion 23 from the hook portion 22 it also, so long as the latch is in the unfastening position, blocks the recess of the hook portion. The two plates 12, 13 are provided with apertures and the latch has a smaller aperture to enable it to be moved to the unfastening position. The curvature of the hook portion 24 of the latch and its relation to the pivot pin 17 is such that forces acting between the fastening and the member 7 do not tend to move the latch to its unfastening position. The plates 12, 13 are provided with aligned elongated apertures 42 through which a belt is passed; a curved plate 44 also passes through the apertures and engages the belt. The plate 44 has a tongue 47 by which the fastener can be attached to a vehicle when the belt is not in use. The member 7 which is engaged by the fastening is attachable to the floor of the vehicle so that it can pivot by means of a member 11 and nuts and bolts.

Patent GB-419908-A (GB)
Title: Improvements in or relating to automatic binding machines
IPC: A01D39/00
Filed: 1934-01-20
Abstract: 419,908. Binding apparatus. TREMOUROUX, C., DenÚe, Namur, Belgium. Jan. 20, 1934, Nos. 2064 and 2065. Convention dates, Jan. 21, 1933 and June 10, 1933. [Class 6 (iii).] A binding machine in which the binding mechanism is set in operation when the machine encounters heaps of material resting on the ground comprises an inverted U-shaped frame 2, 3, 4 of which an upright 2 is pivotally carried by a shaft 7 mounted in the bifurcated end of an adjusting lever adapted to pivot about the axle 9 of a carrying wheel 10 ; the other upright 3 is adjustably supported on a wheel 71 by a screwthreaded sleeve 73. Motion is transmitted through chain and sprocket gear from the axle 9 to the shaft 7 and thence to a shaft 19 in the upper part of the frame that carries a bevel wheel 20 driving a gear 21 idle on a vertical shaft 23 and integral with a ratchet wheel 22. A crank member 24, keyed to the shaft 23, is attached by a bolt 60 to a cam member 59 encircling the ratchet wheel 22 and is provided with guides for a spring catch 25 adapted to lock the crank member to the ratchet wheel but maintained out of such locking engagement when a bell crank lever 27 is engaged by a stop piece 29. This stop piece is retracted, to permit the binding mechanism to be actuated, by a strap 29a being engaged by an eccentric member 35b connected by a chain 34 to a nose piece 33 keyed to a vertical shaft 32 this shaft carrying a resilient blade 31 that is engaged by and pressed backwards when a heap of material to be bound is encountered. The retraction of the stop is effected against the pressure of a spring 36 which causes the tripping blade 31 and associated mechanism to return to their original positions after the heap of material has been bound. The rotation of the crank 24 oscillates a gear 37 mounted freely on a shaft 38 and meshing with gears 39, 45: the gear 39 is connected by a rod 41 to a crank arm 42 keyed to the shaft 38. A vertical shaft 44 mounted on an extension of the crank arm 42 and a similar arm 43 keyed to the shaft 38 carries the gear 45 at its upper end and a needle 46 at its lower end. As the gear 37 oscillates, the needle 46, in addition to its usual rotary movement, is swung about the axis of the shaft 38. The shaft 32 is likewise carried by the arms 42, 43, the movement thus acquired preventing excessive movement of the stop 29. The needle compresses the material against a retaining blade 50 and a guide plate 48. The blade 50 is carried by a vertical shaft 54 provided with a crank 55 connected by a link 56 with an arm bearing against the cam member 59: the cam member has a recess that permits the blade 50 to move out of the way when the sheaf has been bound. The knotter and a discharging arm 70 are actuated by the shaft 23. A bar 61 provided with spikes 62 is given a swinging movement to engage the heap of material and to assist it towards the rear of the machine by a link connection with the crank 24.
