Application August 17, 1944, SerialNm 549,866
This invention, relate to projectors and more particularly to asling-type projector adapted for propelling an object through the air by the useof resilient means.
A primary object of this invention is. the provision of an improved sling-type. projector adapted for the hurling of weights or the, like to a relatively great distance.
An additional object of the invention is the provision of such a projector embodying a plurality of resilient means, such as springs, to effect a multiplication of the propulsive force thereof.
A still further object is the provision of such a device so constructed and arranged as to be readily mobile.
Astill further object is the provision of a projector adapted for the hurling of weights, grenades, rockets, or the like, a a weapon, which will be comparatively noiseless in operation, and hence difficult of detection.
Still further objects reside in the combinations of elements, arrangements of parts, and features of construction, all as will be more fully pointed out hereinafter and shown in the accompanying drawing, wherein there is disclosed a preferred embodiment of this inventive concept.
In the drawing- Figure 1 is a front elevational view ofa slin type projector constructed in accordance with this invention, and
Figure 2 is a top plan view of the device shown in Figure 1,
Like reference numerals refer to like parts throughout the several views of the drawing.
In the drawing, a supporting base or platform generally indicated at [0, is comprised of a relatively flat urface ll, of considerable cross-sectional area, on which is adapted to be mounted a supporting frame generally indicated at l2, the balance of platform ll providing a space for the support of projectiles, adapted to be hurled by the device in a manner to be described hereinafter.
From the lower side of platform I 1 frame members l3 extend downwardly and inwardly and support at a point adjacent their lower extremities an axle I l on which is mounted a wheel I5, members I 3 and axle l4 being secured in related assembly in any desired manner. Suitable sup ports l6 are provided adjacent opposite rear corners of platform I 1 whereby the same when positioned for operation may be in substantially level alignment with the ground or other supporting surface therefor. Suitable handles I! extend 6 Claims. (Cl. 124-46) rearwardly fromsupporting platform Ill, whereby the device may bezreadily movedas desired.
Frame I2; is, comprised. of; a. base, member 20 secured in any suitable; manneras by bolts or rivets 2| adjacent the; forward ed e of platform H, vertical portions 22 extending upwardly a substantial distance above base portion 20 and U-shaped portions 23 extending horizontally at substantially-right angles to vertical portions 22. Suitable apertures 24 are cut at spaced intervals through U-shaped members 23,, and. are adapted to have secured thereintheends oftension springs 25, which springs extend inwardly. with respect to the U-shapedportions 2.3. Secured to'the free ends of each. of springsI 26- except. those, 26a, positioned most nearlyv adjacent the central portion of U-shaped members23, is a pulley 21.
Secured to the free end of. one of springs 26a is, an end, of, a cord, strap, or similar flexible member 28;, the intermediate portion of which is passed alternately through pulleys 21' secured to opposite legs of portions 23, of the frame,,the opposite end after such passage being secured to the inner end' of" the other of springs 26a.
It may here be pointed out that the legs of U-shaped members 23, which may be constructed of relatively resilient trip metal or the like, terminate at points substantially in alignment with vertical portions 22; thus forming a centrally disposed channel with respect to U-shaped portions 23.
From the foregoing the operation of the device should now be readily understandable. A projectile 30 which may comprise any suitable missile is engaged with cord 28 at a point intermediate thereof between the innermost pulleys 21 in the channel formed between the upright vertical members 22. As the weight 30 and the associated cord 28 are drawn rearwardly in the direction indicated by the arrow in Figure 2, all of springs 26 and 2611 are tensioned, and simultaneously the relatively resilient legs of portions 23 are drawn inwardly with respect to each other. Obviously, upon release of weight 30 the tension of all the springs as well as that of U-shaped portions 23 will be simultaneously released and the weight hurled forwardly through the channel formed between vertical portions 22, by the action of cord 28 thereupon. It will also be seen that due to the resiliency of springs 26, weight 3|] may be positioned at an angle with respect to the horizontal plane of portions 23 and accordingly its direction of flight, in a vertical plane, controlled. Thus, there is herein provided a slingtype projector accomplishing all the object of 3 this invention and others including many advantages of practical utility.
Obviously, the device may be made in any desired size, adapted to hurl missiles of various weights to various ranges, for any desired purpose.
As many embodiments may be made of this inventive concept and as many modifications may be made in the embodiment hereinbefore described and shown in the accompanying drawing, it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a.
limiting sense.
I claim:
1.
