SPEAR.

Specification of Letters Patent.

Patented Nov. 5, 1918.

Application filed January 10, 1918. Serial No. 211,258.

To all whom it may concern;

Be it known that I, ABRAHAM MAX HOLTZ- MAN, a citizen of the United States, and resident of the borough of Brooklyn, county of Kings, city and State of NewYork, have invented certain new and useful Improvements in Spears, of which the following is a specification.

The device the subject of this invention ed for'the purpose of capturing and training wild animals, although from the description which follows, it will probably be appreciated that the device may be used for aggression or protection under almost any conditions.

The device proper is a spear having all of the advantages of the ordinary spear,

- and in addition thereto, certain additional mechanisms for definite purposes that will be fully described in the specification which follows.

The following is what I consider a good means for carrying out my invention, and the accompanying drawings should be referred to for a complete understanding of the specification whlch follows.

In the drawings:

Figure 1 is an elevation partly in section, and shows a complete device.

Fig. 2 is a view taken at right-angles to Fig. 1.

Fig. 3 shows a part removed, and

Fig. 4. shows a clamping device.

Figs. 3 and 4: are on an enlarged scale.

Similar reference numerals indicate like parts in all of the figures where they appear.

My spear, like ordinary spears, is provided with a shaft and a spear-head.

The spear-head may be of any size or design, but in the figures of the drawings, I have shown what is termed a knife-blade spear, a long, pointed knife-blade 1, pivoted to a shaft and capable of moving upward or downward relative to the line of the shaft.

The knife-blade 1 is received in a hilt, and the hilt is formed with a plurality of jaws 2 and 3, and a pivot 4 secures the knife 1 between the jaws 2 and 3, and allows the knife 1 to rock, or partly revolve to a slight extent between the jaws and upon the pivot 4, and formed integral with, or secured to the knife 1, is a projection 5 for a purpose that shall appear later.

Y the shaft, I arrange a plurality of cells of a strip 13 of insulating material such asmica or any other suitable insulation.

Wires from the coil 13 and from the vibrator 14 are connected one to each portion of the knife.

Low down, and upon the shaft 6 I secure a plate having a plurality of sectors 1e and 15 and in each sector I arrange a revoluble clamping ring 16 and in each clamping ring I secure a gun or revolver 17 and 18, and in the drawings, I have shown so-called automatic guns secured in the clamps.

Extending parallel with the shaft 6 and supported and secured thereto is a rod 19, the upper end of which is more or less closely adjacent to the projection 5, before referred to. An adjusting sleeve 20 on the rod 19 allows the relative position of the upper end of the rod and the projection5 to be varied at will and a spring 21 upon the rod 19 and the bearing upon a block 22 secured to the shaft 6 urges the rod 19 upward.

The lower endof the rod 19 is pivotally connected to the partially rotating levers 23 and 24, and the free end of each of these levers is arranged adjacent to and in operative relation with the trig er of one of the guns 17 and 18, and a ownward movement of the rod 19 will cause the levers 23 and 24 to depress the triggers and discharge the guns. As the guns may be revolved in their sectors, the levers 23 and 24 are formed in the shape of arcs so that they will be operative egardless of the direction in which the guns are pointed.

A rod 25 extends downward parallel with the handle 26 of the shaft 6, and this rod 25 is preferably located in a groove. in the handle and is provided with a projecting button 27 The rod 25 has a cross-arm 28 at its upper end and connected to the cross-arm are movable semi-circular levers or guides 29 and 30, each connected with one of the guns 17 and 18, and by means of the longitudinal movement of the rod 25, the direction or aim of the guns 17 and 18 is changed at will.

I provide a strap 31 for my spear, this strap serving "the ordinary functions of the straps usually employed with spears.

The operation of my device is probably well understood from the foregoing description. I will, however, call attention to the general operation so that the relationeof the parts may be more fully ,understood- It is well lmown that most animals are particularly sensitive to electric shocks, the reason usually assigned to this super-sensitiveness is the surprise of the shock, and instances are recorded where evenjlarge animals have been rendered apparently unconscious by an electric shock of smallcapacity. I'utilize this characteristic of animals by the employment of a particularly powerful Ruhmkorfl coil and a plurality of cells which insure the delivery of a vibratory current of considerable strength, and I may provide means, as an ordinary switch, for connecting and disconnecting the coil from the battery sothat its use may be regulated.

The spear is used for ordinary purposes,

and, when, for instance, in close engagement, when it is not desired to kill the beast or animal attacked, the coil and battery are connected, and when the point of the spear pierces the hide of the beast, the shock de-' livered will, in my belief, so'affect the beast that it will discourage further attack. I

adjust the position of the upper'end of the rod 19 and should the spear fail to stop the onrushing animal, the rod 19 will be pressed backward and both of,the guns 17 and 18 will be discharged. It is not, however, my purpose to utilize the guns unless it be found absolutely necessary, and therefore. I am tightening the pivot 4 to such an extent that it will require a direct and intentional a movement of the shaft 6 out of the line of thrust to cause a discharge of the guns.

Were my spear to be used in warfare, and particularly when fighting a line of close formation, ability to change the angle of the guns would be of great advantage.

It is quite obvious that modifications may be made in the construction or in the opera- 'tion of my device, but I prefer thewhole as shown and described. I Having carefully and fully described my .invention, what I claim and desire to secure by Letters Patent is:

1. Aspear, the blade of which is adapted to be nioved independently of the shaft and a plurality of fire-arms adapted to be discharged by movement of said blade.

2;A spear having a blade in two parts in- Qsulated from each other,-a battery and coil in-the shaft of said spear, and connected to said blade. 7

3 A spear, a sector mounted thereon, and a gun rotatable 1n sald sector, and means eX- tending adjacent .to the blade of said spear for discharging said gun.

4. A spear having a plurality of guns rotatably mounted thereon, means for changing the angles of said guns, and means connected with said guns, and extending adjacent to the blade of said spear for discharging both said guns simultaneously.

Signed at New York city, county and State .of New York this 22nd day of December, 1917 ABRAHAM MAX HoL'rz MAN.
