BOW OR ELASTIC DEVICE FOR PROPELLING PROJECTILES SUMMARY OF THE INVENTION A missile launcher having a power means for effecting a launch, and having an adjustable lock for maintaining the missile-launching means in a selected position for launching, and novel triggering means for effecting a launch and for releasing the lock after the missile is launched.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of the device, showing the missile projector locked in a selected position for launching.

FIG. 2 is a perspective view of the device, showing another type of missile mounted in the launching means.

FIG. 3 is an enlarged elevational view, partially in cross section, of the missile pocket and trigger connection.

FIG. 4 is a top plan view of the structure shown in FIG. 3.

FIG. 5 is a top plan view of the forward end of the launching lock housing and the track it is mounted in.

FIG. 6 is a side elevational view, in cross section, of the loci;

and track, taken on the line 6-6 of FIG. 5, and

FIG. 7 is a side elevational view of the missile-launching lock, in cross section, showing the trigger mechanism position immediately after the missile has been launched.

DESCRIPTION OF THE PREFERRED EMBODIMENT In the drawings the numeral 1 designates a base member having a flat upper surface 2 on which the tracks 3, 3 are mounted, such as by anchoring angle irons thereon, the overturned portion of the angle irons extending over said upper surface and being spaced a sufficient distance from said surface to provide a free space for the baseplate 4 of the lock housing 5 to slide. A series of longitudinal axial openings 6, 6 are formed in the surface 2 of the base member, which have their forward end faces vertical and their rearward end faces tapered, and a releasing bar 7 extends rearwardly from the forward end of said base member surface 2.

A power means, such as the rubberbands 8, 8, secured to the upright posts 9, 9 has the missile pocket 10, which may be formed of leather or fabric, one end being a flat vertical wall, and the sidewalls being tapered forwardly. One end of a swivel connector, as 11, is sewed between the several layers of the material of the pocket at the end of the taper of each sidewall, and the other end of the respective swivels receives one end of the respective rubberbands 8, 8. A small bit of fabric, as 12, is faced against the inside wall of the rubberband where it is tied to the swivel to prevent the rubber from creeping, and escaping the tie. A vertical plate 13 is mounted between the layers of material at the other end of the pocket 10, and a threaded shaft 14 extends laterally from the plate 13 to receive the latch 15, which has a threaded chamber in one end for that purpose.

The trigger mechanism consists of a suitable housing 5 in which the mechanism is mounted, and the launching trigger assembly is mounted in the upper half of the housing, and has the spring loaded upper pivotal bar 16 and the spring loaded lower pivotal bar 17. An upstanding pawl 18 is integral with the lower bar 17 and has the laterally extended finger 19 against which one end of the bar 16 bears. The control bar 20 extends through the housing 5 and a laterally projecting stud 21 is in position to bear against one end of the pivotal bar 16 when the bar 20 is depressed, causing the other end of the bar 16 to lift the pawl 18. The lower end of the pawl 18 extends beneath the pivotal bar 17 and engages the latch 15. As the pawl 18 is lifted, the latch is released. A stop 31 limits the downward movement of the bar 17.

A partition 22 divides the upper and lower trigger assemblies, and forms a guide for the latch 20. The lower assembly consists of the upper spring loaded pivotal bar 23, the lower spring loaded pivotal bar 24 and the pawl 25, which is integral with the lower bar 24. A stop 35 limits the lower movement of the bar 23 and the plate 4 limits the lower movement of the bar 24. The pawl 25 has the laterally extended finger 26 against which one end of the upper bar 23 bears. The lower end of the pawl 25 extends below the lower pivotal bar 24 and through an orifice 27 in the baseplate 4 and abuts one end of the respective axial openings 6. The lower end face of the pawl 25 is tapered upwardly rearwardly, so that it will readily slide up the slanted face of the orifice6. The pawl 25 is notched to receive the tapered projection 28 of the spring loaded pivotal latch 29. The lower end of the latch 29 extends through the orifice 27 of the baseplate 4, but does not extend into the openings 6. The pawl 25 has a notch on one longitudinal side face, as 30, positioned to receive the tapered projection 28 when the pawl 27 is lifted out of engagement with the end face of the opening 6. As the bar 20 is depressed, the latch 15 is released first and as the depressing action continues, the bar 23 is pivoted to raise the pawl 25 and as the lower end of the pawl 25 clears the opening 6, releasing the housing for sliding action in the tracks 33, and as the depression of the bar 20 continues, the tapered portion 28 of the latch 29 enters the notch 30 of the pawl 25 and holds the pawl 25 in raised position. When the housings is moved all the way forward in the tracks 3, 3, the bar 7 contacts the lower end of the latch 29 and pivots the same, moving the tapered member 28 out of the notch 30, permitting the bar 24 to return to lowermost position and the pawl 25 to move downwardly into engaging position with the straight end wall of the respective openings 6.

In use the missile may be seated in the pocket 10 and the latch inserted into the upper assembly through the opening 32 until in engagement with the pawl 18 as shown in FIG. 6, and the housing 5 then pulled backwardly, the pawl 25 moving upwardly as the lower end thereof contacts the slanted ends of the openings 6, this upward movement being short of sufficient to engage the latch 29, until the housing 5 is in the desired position, and at which position the pawl 25 will be abutting the vertical face of one of the openings 6.

The rubberbands 8, 8, or the like, may be replaced with the bow 33, the bow 33 being anchored to the posts 9, 9 and the bowstring 34 being secured to the pocket 10 by means of the swivels ll, 11.

Many types of missiles may thus be launched. Solid missiles, such as rocks, balls, or the like, as well as explosives, such as firecrackers, grenades, or the like, as well as arrows in all forms.

What is claimed is:

l. A missile launcher having a baseplate, track guiding said base member means for propelling a missile mounted on said base member, locking means movable mounted on said base member for releasably locking the means for propelling a missile in several positions along said track, a missile pocket mounted on said missile-propelling power means, a latch on said pocket engageable by said locking means, means for manually releasing said latch and said locking means, said last mentioned means being manually reciprocated through said locking means, and said means for releasing said latch comprising a member biased into engagement with said latch, a pivoted lever means disposed to lift said member out of engagement with said latch, and a manually actuable shaft reciprocally mounted rearwardly of said lever means for pivoting said lever means and lifting said member.

2. The device defined in claim 1 wherein said baseplate is slidably guided by a pair of tracks positioned there above, and a base member having longitudinal openings to receive one end of a pawl from said locking means for locking said locking means in a selected position adjacent said track.

3. The device defined in claim 1 wherein said locking means comprises a housing, said means for manually releasing said latch comprising an upper and a lower trigger assembly in said housing, an actuating shaft extending through both of said assemblies for actuating said assemblies in sequence, said shaft first releasing said missile pocket and thereafter releasing said locking means.

4. A missile launcher having a base member, power means for propelling a missile mounted on said base member, locking means movable mounted on said base member for releasably extending threaded stud and a latch member having one end tapered and the other end having an internally threaded chamber to receive said threaded stud.

5. The device defined in claim 1 wherein a latch-actuating means is positioned in the locking means to contact said latch on the pocket and to reset said locking means after a missile has been launched.
