l Claims. l

This invention relates to a missile and more particularly to improvements in darts, arrows or the like, and has as its primary object to provide a simple yet effective tip for such type of missiles.

Darts and arrows are generally alike in that they each consist of a shank or body having a pointed leading end and a finned trailing end, the main difference being in the length of the shank or body. The present invention contemplates providing darts or arrows with a tip which may be applied during manufacture or which may be sold separately for application to the dart or arrow by the person who desires to use the same.

One object of the present invention is to provide a dart or arrow tip embodying a moveable element adapted to be effected by momentum, upon impact of the tip against an object, for continued movement forwardly 0f the tip.

Another object is to provide a guard for the leading end of a dart or arrow for preventing injury of the user by the pointed forward end of the same.

Another object is to provide a dart or arrow tip which may be made at a minimum of cost so that its destruction, upon use, will amply satisfy the need of the user.

A further object is te provide an arrow tip in which a plurality of momentum actuated elements can be arranged in tandem for adapting the tip for Various uses with equal effectiveness.

Other objects and advantages of the present invention will appear more fully from a reading of the following specification in the lightY of the accompanying drawings in which:

Fig. l is a longitudinal section through a missile tip embodying the present invention.

Fig. 2 is a view similar to that of Fig. l.

3 is a view of the tip of Figs. l and. 2 employed on a dart.

Fig. 4 is similar to that of Fig. 3.

Fig. 5 is a fragmentary section of a tip having another type of missile associated therewith.

Fig. 5 shows a modification of the tip shown in Fig. 3.

Fig. '7 is another view of the tip shown in Fig. 6.

Fig. 8 is an illustration of different manner of using the tip of Fig. 6.

Fig. 9 shows a modified form of tip; and

Fig. l0 is a perspective view of the tip shown in Fig. 9.

'The present invention generally comprises a sleeve-like cap or cover It adapted to be applied to the leading end of a missile such as a dart or an arrow which is to be hurled through the air. The simple form of cap I shown in the drawings consists of an elongated, preferably tubular body I I having a tapered leading end I2 provided with a passage I3 of substantially smaller diameter than the inner bore I 4 of the tubular member I I.

The passage is of any size suitable for receiving a piercing instrumentality so as to permit movement of the latter through the passage I3 and while the passage may be of a fixed dimension, it is preferably formed to receive interchangeable sleeves, such as the insert I5 provided with a passage I3, to suit the particular form of piercing instrumentality it is desired to employ.

Referring now to Figs. 1 to 5 it will be noted that the inner bore I4 of the tubular body II is adapted to receive the pointed end of an arrow 2i). The arrow 2i)y ts more or less snugly with respect to the inner bore I4 so that the tip will stay on the arrow shaft during flight, but is sufliciently loose with respect to the bore Id as to permit its sliding within the bore when the leading end of the body hits an obstruction. Consequently, when the arrow is shot from a bow against a target T the shaft of the arrow 20 will remain juxtaposed with respect to the body II, but will continue to move forwardly under its own mom-entum when the tip is obstructed by target T.

In Fig. 1, the piercing instrumentality is in the form of a nail or pin 2| having its pointed end 22 arranged for sliding movement in the passage I3' of the insert I 5 in the passage I3 of the body II. The head 23 of the pin 2| is disposed within the inner bore It of the body and is adapted to abut against the pointed end of the arrow 2U. If desired, a coil spring 2li is arranged on the pin, i. e. between the head 23 of the pin and the forward wall of the bore I4, so'as to maintainV the pin in' a retracted position with respect to the leading end of the tip. In this manner the pointed end of the pin 2| is heldback in the passage I3 where it will not ybe likely to catch onto a persons clothing while the tip vis carried in ones pocket and moreover will not scratch or otherwise injure the person handling the tip.

When the arrow 20 of Fig. 1 is shot at the target T in' the. manner as explained above, and the tip is obstructed by the target, the arrow constitutes a hammer which continues to move forward under its own momentum, forcing the pin ZI forwardly against the action of the spring 2d thereby driving the pointed end 22 of the pin 2| out of the passage I3 and into the target T. Consequently, the pointed end of the pin pierces the target and will remain in the same, as illustrated in Fig. 2.

From the foregoing it will be appreciated that during competitive archery each contestant may be supplied with tips of a distinct color so that even though the arrows may rebound from and become detached from the tip, the latter will remain stuck in the target to indicate the hits made by each particular contestant. In the event the tips are made of material which will be broken upon impact with the target, the pins can be colored so that despite the destruction of the tip, the pin remaining in the target will indicate the hits and will enable proper identication of the pin with the persen scoring the hit.

Moreover, from the foregoing it is apparent that the target need not be the conventional straw filled type usually required in order to prevent breakage of the arrows. In other words, the tip acts as a shock absorber and therefore the full impact of the arrow against the target is lessened so that damage to the arrow is improbable. Therefore it is not essential that a regulation target be used, since any wooden wall Such as a fence or the side of a barn may serve as a target. Being able to use boards or logs for targets is advantageous especially during informal hikes and outings.

The tip being suitable for adapting the missile for projection against a wooden wall or the like is particularly advantageous when the tip is employed with a dart 3Q in the manner as shown in Figs. 3 and 4. In such event the dart 35 may be a weighted body having fins 3l at its trailing end and a piercing point 3B at its leading end for movement through the passage I3 in the sleeve I5 of the body II.

yIhe dart 33 ts into the bore I4 in the same manner as did the shaft of the arrow 23 so that the pointed end of the pin 32 is maintained well within the passage I3'. In this manner the dart with tip attached may be carried in the pocket of ones clothing without danger of the pin 32 injuring the person carrying the dart.

The sleeve I5, when withdrawn from the tip body I I leaves the passage I3 clear for the reception of a bullet 35, such as a .22 calibre cartridge, see Figs. 5, 8 and 9. The tip of Fig. 5 may be employed with either a dart or an arrow in the manner illustrated in Figs. 3 and l, respectively, and it will be noted that the leading end of the dart or arrow provides a firing pin or hammer adapted to strike the cap of the cartridge to detonate the same. In this adaptation of the present invention, upon impact of the tip with an obstruction, the momentum of the body behind the firing pin causes the latter to fire the cartridge whereupon the bullet is shot from the passage i3 directly into the object struck by the tip. Should the cartridge 35 be of the rim-lire type, the firing pin may be offset as shown at 36 in Fig. 5 so as to properly detonate the rim-nre cap in the cartridge.

The modification shown in Figs. 6 and '7 illustrate the tip of the present invention in use with an ampule of drug. The ampule 4I? has its neck inserted in the passage I 3 and its main body disposed in the bore Iii just in advance of the momentum actuated member associated with the tip. It is apparent that either the dar-t or the arrow may be employed as a momentum actuated member in a tip loaded with an ampule. However, n Figs. 6 and 7 the form of momentum actuated member is in principle, similar to the types hereinbefore explained, except that it constitutes a self contained unit 45. This unit comprises 1an elongated hollow body 46 having an opening 41 in its leading end and a plug 48 threaded into its opposite end. The body 46 ts in the bore I4 as did the dart and arrow, and may carry the fins or the ns may be secured Ato the body II. A piercing pin 49 is disposed in the hollow of the body 46 with its pointed end in the opening 4'I and its headed end within the hollow body 46. A weight in the form of a ball 5I) is also disposed in the hollow body 45 in back of the headed end of the pin 4S for exerting a force lagainst the pin due to momentum when the tip meets an obstruction during flight. Upon impact of the tip against an object the ball 5I) exerts a sudden forward thrust against the pin 43 and the pin 49 is thereby driven through the ampule 4U. The ampule 40 is therefore broken and the pin 49 wet with the drug as it advances through the passage I3 and enters the object struck by lthe tip.

The foregoing is especially useful as a missile for inoculating animals to render lthem temporarily insensible for a sufcient lapse of time as to permit the capture and transfer of such animals to a cage.

Fig. 8 illustrates a variation of the present invention in which the momentum uni-t 45 of Fig. 6 is shown in use With the bullet 35 of Fig. 5 instead of the ampule 4i). The same arrangement as above explained lis embodied in the modification of Fig. 9. In this structure the momentum device 45 carries the ns and a sleeve-like outer shell 52 is slidably mounted on the body I I. The forward end of the shell 52 is provided with pointed tines 53 adapted to pierce the object or target T so as to secure the tip thereagainst upon impacting with the same and incident to the discharge of the cartridge 35. It is apparent that if the tip is made up with the insert I5 in .the passage I3 and with the pin 2| of Fig. 2 disposed in the passage I3', the device of Fig. 9 operates in the same manner as explained above except that the pin 2I will enter the target T as do the tines 53.

I desire that it be understood that the various elements herein described may be interchanged with each other in numerous ways other than the specic examples mentioned and that while I have described these elements in detail it will be appreciated by those lskilled in the art that the same may be altered and/or varied in construction without departing from the spirit of this invention. I therefore desire to avail myself of all variations, modifications and alterations in construction as come within the purview of the appended claims.
