Specification Accepted, 18th May, 1889 -
I, FRANOIS SINNATT, of 53 Everton Road, Liverpool, Manager, do hereby declare
the nature of this invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The improvements relate to toys of the arrow or dart kind, and have for object the
rendering of the same capable of exploding a detonator on striking any resisting
object or the earth.
To accomplish this, and to effect my improvements, I form the head of the dart or
arrow, by preference, with a projecting thin metal or other tube or cylinder attached
thereto in any suitable manner.
Within this cylinder, a piston is free to slide loosely.
Near the end of the arrow or dart shaft, a small slot is cut, through which the
detonator, by preference the toy detonators as at present used for toy pistols and
the like is inserted. The toy arrow or dart is then ready for either throwing by
hand, or propulsion from an ordinary or cross bow, or from a toy gun.
On the end of the piston striking a resisting object, or the ground, the piston is
driven with sufficient force on to the detonator, to explode the same.
Any convenient means may be employed for securing the piston from falling out of
the tube or cylinder, and the ends of the arrow or dart may be covered or not with a
metallic plate which may be part of the tube or casing forining the head of the dart
or arrow, or otherwise.
A modification of the invention may be made by forming a head to the arrow or
dart which may be temporarily held in position by means of an elastic band or other
spring, between which head, and the end of the arrow or dart the detonator may
be placed.
But that the improvements may be better understood, I will, by the aid of the
accompanying drawings proceed more fully to describe means employed by me.

page_text: Figs. 3 and 4 shew two views at right angles to each other of the modification
herein named.
A is the dart or arrow shaft ; B is the cylinder or tube attached to the end, which
in this case is by means of the small indentations in the tube as shewn at E E.
C is the piston which slides loosely in the tube B, and in the case shewn is
prevented from falling out by indentations made in the tube taking into a groove
in the piston, but other means may be employed both for securing the tube to the
shaft A and for preventing the falling out of the piston C.
D is the slot for the insertion of the detonator paper or cap, and H are strips of
paper or card, or it may be feathers as commonly used in darts or arrows.
In the modification, F is the head, in lieu of the piston, which is held in position by
means of the elastic band G.
Variations in form and detail may be made, both in the arrows or darts themselves,
and in their heads, together with the mode of their use as toys without departing
from the peculiar character of the invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. Arrows or darts, employed as toys, having heads formed with movable pistons
for the purpose of exploding detonators when such arrows or darts strike a resisting
object or fall to the ground, in manner substantially as herein shewn & described.
2. Arrows or darts, employed as toys, baving movable heads for the purpose of
exploding detonators when such arrows or darts strike a resisting object or fall to the
ground, in manner substantially as herein shewn and described.
