Hqzrs A-Dou91qs IN VLNTOK rmWz/w AT T0 KNLTS Patented Feb. 9, 1937 UNITED STATES PATENT OFFICE Application September 26, 1934, Serial No. 745,552 Renewed July 2, 1936 16 Claims.

This invention relates to missile projecting devices, and has for an object the provision of a new and improved device of this character.

In the drawing accompanying this specification and forming a part of this application, I have shown, for purposes of illustration, one embodiment which my invention may assume, and in the drawing:

Figure 1 is a side elevational view of a missile projecting device constructed according to the invention;

Figure 2 is a fragmentary enlarged vertical sectional view of the device shown in Figure l, disclosing the operative parts in a normal position of rest;

Figure 3 is a view similar to Figure 2, and disclosing the operative parts in position to discharge the missile;

Figure 4 is an enlarged fragmentary perspective view of one end of the bow, and showing the manner in which the bow string is attached thereto, while Figure 5 is a fragmentary vertical sectional view of the projecting device, showing another 5 embodiment of the invention.

As shown in the drawing, the invention comprises a missile projecting device, including a bow 6 of suitable resilient material, to the ends of which is secured a bow string 1 looped and knotted as best shown at 8 in Figure 4.

The bow 6 is perforated at a central point, as indicated at 3, and extending through the perforation 9 is a combined cylinder and barrel member, the cylinder It being of substantial diameter,

open at one end, as indicated at H, and the opposite end l2 snugly fitted into'the perforation 9 in the bow 6, the cylinder H) being provided with an exterior annular flange l3 which abuts the inner surface of the bow 6, and being further provided with an annular flange l4 closely fitting against the opposite surface of the bow B, the latter flange being formed from an initially cylindrical projection, indicated in dotted lines in Figure 3, which is upset by a suitable operation subsequent to insertion through the perforation 9, resulting in the bow 6 being firmly clamped between the flanges l3 and M.

The cylinder H) has a bore l5 tapered at its inner end and further reduced, as indicated at I6, and immediately in advance of the reduced bore l6, there is provided a rounded seat I! for accommodation of a ball missile l8, and the rounded seat i1 merges with the cylindrical bore 19 formed in the barrel 2b. The barrel 20 projects forwardly of the bow 5a considerable distance and is preferably formed integrally with the cylinder member H]; in fact the cylinder l0 and barrel 20 may be bored from one casting resulting in a strong and accurately furnished con- 7 struction. A piston 2| is reciprocably mounted 5 in the bore I5 of the cylinder ID and is provided with a rod 22 having a perforation 23 in its end through which the bow string freely passes.

In Figure 5 there is shown a slightly different embodiment of the missile projecting device; in 10 this embodiment the bow 25, cylinder 26,

flanges

21 and 28, barrel 29 and piston 30 correspond to the parts 6, I0, 13, M, 20, and 2| heretofore referred to, and a bow string, not shown, similar to the bow string l is also used. The interior con- 15 struction of the cylinder 26 and barrel 29 differs, however, in order to accommodate a different type of missile, such as a dart 3|, the bore 32 of the barrel 29 being of a size to snugly accommodate the shaft of the dart 3|, and the passage 33 is 20 made smaller than the diameter of the dart shaft, and communicates with the bore of the cylinder 26 in the same manner as before described,

In operation a ball I8 is inserted into the bore I9 of the barrel 20 so as to rest against the seat 5 I1, the bow 6 being then grasped and supported by one hand of the user, and the'stringl pulled back to bend the bow 6 and retract the piston 2|;

when the string 1 is released air is compressed within the cylinder l0, and ejects the ball l8 from 30 the barrel 20. The construction shown in Figure 5 operates in a similar manner.

It will be appreciated that the device is manipulable exactly in the manner of an ordinary bow, yet is more powerful and accurate in its shoot- 35 ing qualities than the ordinary bow and arrow, and by reason of its construction is ideally suitable for use as a toy, though equally suitable in large size as an effective weapon.

Under these circumstances it will be apparent ,40 to those skilled in the art that I have accomplished at least the principal object of my invention. On the other hand, it also will be apparent to those skilled in the art that the disclosure herein is illustrative only, and may be various- 1,5 ly and extensively modified, while still retaining part or all of the advantages of my invention, and without departing from my invention, and that my invention in no sense is limited to this or any specific embodiment or disclosure. 5,0
